Description

本発明は、建物の二重天井に吊り下げられた吊りボルト等のボルト体に配線・配管材、配線ボックス等の配設体を支持させたり、該ボルト体にケーブルラック等の配設体を設置したりするために用いられる、ボルト体への取着体及びナット体に関するものである。   The present invention supports an arrangement body such as a wiring / pipe material, a wiring box or the like on a bolt body such as a suspension bolt suspended from a double ceiling of a building, or an arrangement body such as a cable rack on the bolt body. The present invention relates to an attachment body to a bolt body and a nut body that are used for installation.

従来より、ケーブル等の配線材や給水管等の配管材などの配設体を建物の二重天井空間等に布設するときには、天井から吊り下げられた吊りボルト等のボルト体に支持具等の取着体を取着し、この支持具等にケーブル等を支持させることが行なわれている。   Conventionally, when laying an installation body such as a wiring material such as a cable or a piping material such as a water supply pipe in a double ceiling space or the like of a building, a support member or the like is attached to a bolt body such as a suspension bolt suspended from the ceiling. An attachment body is attached and a cable or the like is supported by the support or the like.

また、ケーブルラック等の配設体を設置するときには、図１９に示すように、天井から垂設された一対の吊りボルト４１，４１の間に断面略Ｌ字形状の鋼材４７を水平状態に配置し、鋼材４７の両端部を吊りボルト４１に螺着された一対のナット５５，５５で上下方向から挟み付けて固定した後、この鋼材４７の上にケーブル４２を支持するケーブルラック４８を載置することが行なわれている。なお、鋼材４７において吊りボルト４１が貫通する部分には貫通孔或いは切欠孔が設けられている。   When installing an installation body such as a cable rack, as shown in FIG. 19, a steel material 47 having a substantially L-shaped cross section is horizontally arranged between a pair of suspension bolts 41, 41 suspended from the ceiling. Then, both ends of the steel material 47 are fixed by being sandwiched and fixed from above and below by a pair of nuts 55, 55 screwed to the suspension bolt 41, and a cable rack 48 that supports the cable 42 is placed on the steel material 47. To be done. Note that a through hole or a notch hole is provided in a portion of the steel material 47 through which the suspension bolt 41 passes.

一方、前者のケーブルを支持する、ボルト体への取着体である支持具としては、例えば、特許文献１に記載のケーブル支持金具が知られている。このケーブル支持金具は、図２０に示すように、弾撥性を有する鈑材からなり略く字状に屈曲形成された金具主鈑５２の長手方向両端近傍部に、切欠部を備えた一対の取付部５３が設けられている。そして、金具主鈑５２の略中央部には、ケーブルを支持するフック状のケーブル抱持杆５４がねじ止めによって取付けられている。   On the other hand, as a support that is an attachment to a bolt body that supports the former cable, for example, a cable support fitting described in Patent Document 1 is known. As shown in FIG. 20, this cable support metal fitting is a pair of notches provided in the vicinity of both ends in the longitudinal direction of a metal main body 52 made of a resilient material made of elastic material and bent into a substantially square shape. A mounting portion 53 is provided. A hook-shaped cable holding rod 54 that supports the cable is attached to the substantially central portion of the metal fixture main rod 52 by screwing.

この支持金具５１は、金具主鈑５２を弾性復帰力に抗して湾曲させて取付部５３にボルト体である吊りボルト４１を貫挿させることにより、金具主鈑５２の弾性復帰力によって取付部５３の周縁５３ａが吊りボルト４１に圧接して固定される。これにより、この支持金具５１を介して吊りボルト４１の軸方向の途中にケーブルを支持させることができる。   The support metal 51 is bent by the elastic main body 52 against the elastic restoring force, and the mounting bolt 53 is inserted into the attachment portion 53 by the elastic bolt of the metal main body 52 so that the mounting portion is attached to the mounting portion. A peripheral edge 53a of 53 is pressed against the suspension bolt 41 and fixed. Thus, the cable can be supported in the middle of the suspension bolt 41 in the axial direction via the support fitting 51.

実開昭５３−１４６０９７号公報Japanese Utility Model Publication No. 53-146097

しかし、前記公報に記載の支持金具５１は、金具主鈑５２の両端の間隔が一般にかなり大きいので、固定の際に片手で両端を把持し難い。また、この支持金具５１は、弾性復帰力により互いに反対向きに突張る状態で金具主鈑５２を湾曲させつつ側方から吊りボルト４１に係止させる構造となっているから、固定が不安定となり易い。そこで、支持金具５１を吊りボルト４１に安定して固定するために、一般に弾性復帰力の相当大きい金具主鈑５２が使用される。その結果、両端を挟圧して金具主鈑５２を湾曲させるには相当大きな力を必要とした。これらのことから、この支持金具５１は、ボルト体に固定するには、金具主鈑５２の両端を把持し、弾性復帰力に抗して相当大きい力で挟圧し湾曲させつつ上下一対の取付部５３にボルト体を貫挿させなければならないから、大変固定し難いものであり、作業性が良くなかった。   However, in the support metal fitting 51 described in the above publication, since the distance between both ends of the metal main body 52 is generally quite large, it is difficult to hold both ends with one hand when fixing. Further, the support metal fitting 51 has a structure in which the metal main body 52 is bent to be engaged with the suspension bolt 41 from the side while being bent in the opposite directions by the elastic restoring force, so that the fixing becomes unstable. easy. Therefore, in order to stably fix the support fitting 51 to the suspension bolt 41, a fitting main rod 52 having a considerably large elastic restoring force is generally used. As a result, a considerable amount of force was required to bend both ends of the metal fitting main rod 52 by clamping the both ends. From these facts, in order to fix the support bracket 51 to the bolt body, a pair of upper and lower mounting portions are held while holding both ends of the bracket main rod 52 and clamping and bending with a considerable force against the elastic restoring force. Since the bolt body had to be inserted through 53, it was very difficult to fix and the workability was not good.

また、この支持金具５１は、金具主鈑５２の上下一対の取付部５３に吊りボルト４１を貫挿させた後、両端を挟圧する力を解放し、弾性復帰力による戻りによって金具主鈑５２を伸張させて吊りボルト４１に係止固定させる構造となっているから、挟圧を開放した際に、吊りボルト４１の軸方向において所望する設定位置からずれて係止されることが多く、所定位置に固定するのは困難であった。そのため、所定間隔毎に垂設された吊りボルト４１への取着高さにばらつきを生じ易く、ケーブルが上下に少し蛇行して布設されることがあった。   In addition, the support metal 51 is configured such that after the suspension bolt 41 is inserted through the pair of upper and lower mounting portions 53 of the metal main body 52, the force that clamps both ends is released, and the metal main body 52 is returned by the elastic return force. Since it is structured to be extended and locked to the suspension bolt 41, when the clamping pressure is released, the suspension bolt is often shifted from a desired set position in the axial direction of the suspension bolt 41, and the predetermined position It was difficult to fix to. For this reason, the attachment height to the suspension bolt 41 suspended at predetermined intervals is likely to vary, and the cable may be laid in a slightly meandering manner.

次に、前述したケーブルラック等の配設体を吊りボルト４１の軸方向の任意位置に設置するために吊りボルト４１にナット５５を螺着するものにおいては、長尺の吊りボルト４１の中間位置にケーブルラック４８を設置するには、一般に、吊りボルト４１の端部から相当距離にわたって回し込まなければならないため、大変面倒な作業を強いられていた。また、図１９において、予め下側の鋼材４７が吊りボルト４１に架設され、後からその上方に鋼材４７を増設するときには、一旦下側の鋼材４７をナット５５とともに取り外さなければならず、同様にその作業は大変面倒で、多大な時間も要した。   Next, in the case where the nut 55 is screwed onto the suspension bolt 41 in order to install the arrangement body such as the cable rack described above at an arbitrary position in the axial direction of the suspension bolt 41, the intermediate position of the long suspension bolt 41 is used. In general, in order to install the cable rack 48, it is necessary to turn the cable rack 48 over a considerable distance from the end of the suspension bolt 41. Therefore, a very troublesome work is required. Further, in FIG. 19, when the lower steel material 47 is installed on the suspension bolt 41 in advance and the steel material 47 is added to the upper side later, the lower steel material 47 must be removed together with the nut 55. The work was very troublesome and took a lot of time.

そこで、本発明は、ボルト体の所定位置に確実かつ正確に、そして大きな力を要することなく簡単に取着することができるボルト体への取着体の提供を課題とするものである。また、ボルト体の軸方向の任意位置に簡単に取着して締付けることができるナット体の提供を課題とするものである。   Therefore, an object of the present invention is to provide an attachment body to a bolt body that can be securely and accurately attached to a predetermined position of the bolt body without requiring a large force. It is another object of the present invention to provide a nut body that can be easily attached and tightened at an arbitrary position in the axial direction of the bolt body.

請求項１のボルト体への取着体は、ボルト体にその側方から取着される取着部を備えたものであって、前記取着部は、両側に配設された一対の側壁のそれぞれから前記ボルト体の反対側まで延出するとともに、いずれも同方向に開口し前記ボルト体がその軸と直交する方向から挿入される切欠開口が設けられ、更に該ボルト体に係止する係止部が設けられた少なくとも一対の挟持片と、取着状態における振れを防止する振れ止め部とを備えている。そして、前記一対の挟持片は、互いに近接し、前記一対の係止部が互いに離間して、前記ボルト体がその軸と直交する方向から前記切欠開口を通過して前記両係止部間に挿入された後、弾性復帰により該係止部が該ボルト体に反対側から係止することによって、該ボルト体を両側方から挟持するよう形成されている。 The attachment body to the bolt body according to claim 1 includes an attachment portion attached to the bolt body from the side thereof, and the attachment portion includes a pair of side walls disposed on both sides. Extending from each of the bolts to the opposite side of the bolt body , each of which is open in the same direction and is provided with a notch opening through which the bolt body is inserted from a direction perpendicular to the axis thereof , and is further locked to the bolt body. At least a pair of clamping pieces provided with a locking part and a steadying part for preventing shaking in the attached state are provided. The pair of sandwiching pieces are close to each other, the pair of locking portions are separated from each other, and the bolt body passes through the notch opening from a direction perpendicular to the axis thereof, and is between the locking portions . after being inserted, by locking portion is locked from the opposite side to the bolt body by elastic return, it is formed so as to hold the said bolt body from both sides.

この構成について付説すれば、一対の挟持片はボルト体の反対側まで延出するとともに、挟持片に設けられた係止部はボルト体の反対側から係止する構成となっているので、一対の挟持片が互いに近接すれば、一対の係止部は逆に互いに離間することとなる。そして、ボルト体が挿入される際には、一対の挟持片は近接する状態となる一方、一対の係止部は逆に互いに離間してその間隔が広がり、ボルト体の挿入が可能となる。前記取着部は、金属板等で形成され、弾性を有し、両係止部間にボルト体が挿入された後は、一対の挟持片は弾性復帰し、係止部は自ずとボルト体に反対側から係止する。   To add to this configuration, the pair of clamping pieces extend to the opposite side of the bolt body, and the locking portion provided on the clamping piece is configured to lock from the opposite side of the bolt body. When the pair of sandwiching pieces are close to each other, the pair of locking portions are separated from each other. When the bolt body is inserted, the pair of clamping pieces are brought close to each other, while the pair of locking portions are spaced apart from each other to increase the distance between them so that the bolt body can be inserted. The attachment portion is formed of a metal plate or the like and has elasticity, and after the bolt body is inserted between the both locking portions, the pair of clamping pieces are elastically restored, and the locking portion is naturally attached to the bolt body. Lock from the opposite side.

この構成により、取着体は、一対の挟持片による両側方からの挟持と振れ止め部による当接とによって、取着後はボルト体に対して振れることなく即ちボルト体の軸に対して傾くことなく一定の垂直姿勢に安定して保持される。   With this configuration, the attachment body does not shake with respect to the bolt body after attachment, that is, with respect to the axis of the bolt body, by the clamping from both sides by the pair of clamping pieces and the contact by the steadying portion. It is stably held in a constant vertical posture without any problems.

ここで、取着体は、ケーブル等の配設体をボルト体に支持させるために使用される支持具や、ボルト体に取着される配線ボックス等の器具、機器類など、広くボルト体に取着されるものが該当する。なお、前者の支持具等の場合では、取着体は、ボルト体に取着される取着部にケーブル等を支持する支持部などが付設された形態をとる。一方、後者の配線ボックス等の器具類などの場合では、本体部分の配線ボックス等に取着部が付設された形態をとる。   Here, the attachment body is widely used in the bolt body, such as a support tool used to support the arrangement body such as a cable on the bolt body, a device such as a wiring box attached to the bolt body, and equipment. Applicable one is attached. In the case of the former support or the like, the attachment body takes a form in which a support portion for supporting a cable or the like is attached to an attachment portion attached to the bolt body. On the other hand, in the case of appliances such as the latter wiring box, an attachment portion is attached to the wiring box or the like of the main body.

請求項２のボルト体への取着体は、固定部が、一対の挟持片に加えて他の挟持片を備えるとともに、ボルト体の軸方向の異なる位置において交互に異なる側からボルト体に係止する少なくとも計３個の切欠係止孔を備え、振れ止め部が、前記他の挟持片の切欠係止孔によって形成されたものである。   In the attachment body to the bolt body according to the second aspect, the fixing portion includes the other clamping pieces in addition to the pair of clamping pieces, and is engaged with the bolt bodies from different sides alternately at different positions in the axial direction of the bolt body. At least three notch locking holes for stopping are provided, and the steadying portion is formed by the notch locking holes of the other holding pieces.

請求項３のボルト体への取着体は、固定部が、一対の挟持片をボルト体の軸方向に複数組備えたものである。この構成において、前記複数組のうちの少なくとも一対の挟持片は、ボルト体を両側方から挟持するものを構成し、複数組のうちの他の組の一対の挟持片は、振れ止め部を構成する。   In the attachment body to the bolt body according to the third aspect, the fixing portion includes a plurality of pairs of clamping pieces in the axial direction of the bolt body. In this configuration, at least one pair of the clamping pieces of the plurality of sets constitutes a clamp body that clamps the bolt body from both sides, and the other pair of clamping pieces of the plurality of sets constitutes a steady-state portion. To do.

請求項４のボルト体への取着体は、挟持片におけるボルト体の挿入空間が、対向する他側の挟持片の挿入空間との間で、一部がボルト体の軸方向から見て互いに重なり合うよう形成されたものである。
これにより、単に側方からボルト体に強制的に押し付けるだけで挟持片相互の間隔は拡開し、両切欠係止孔内にボルト体が収容され係止される。 The attachment body to the bolt body according to claim 4 is such that the insertion space of the bolt body in the sandwiching piece is between the insertion space of the opposing sandwiching piece and a part thereof is seen from the axial direction of the bolt body. It is formed to overlap.
As a result, the space between the clamping pieces is expanded simply by forcibly pressing the bolt body from the side, and the bolt body is housed and locked in both notch locking holes.

請求項５のボルト体への取着体は、取着部が配設体を支持する支持部を備え、その支持部は、取着部において、挟持されたボルト体の軸心を通る側方であって、該ボルト体の挿入方向と直交する側方に取付けられたものである。別言すれば、支持部は、取着部において、挟持されたボルト体の軸心を通り該ボルト体の挿入方向と直交する平面上に取付けられている。この場合、支持部は、取着部の両側方に取付けてもよいし、いずれか一側方のみに取付けてもよい。   The attachment body to the bolt body according to claim 5 is provided with a support portion in which the attachment portion supports the arrangement body, and the support portion is a lateral side passing through the axis of the clamped bolt body in the attachment portion. And it is attached to the side orthogonal to the insertion direction of the bolt body. In other words, the support portion is attached to the attachment portion on a plane that passes through the axis of the clamped bolt body and is orthogonal to the insertion direction of the bolt body. In this case, the support portion may be attached to both sides of the attachment portion, or may be attached to only one side.

これにより、仮に、支持部が取着部において上記以外の箇所に取付けられている場合は、支持される配設体の荷重が大きいと、上下いずれかの係止部とボルト体との当接部を軸として取着体を回動させようとするモーメントが発生し、取着体は回動してボルト体から抜脱する虞がある。しかし、請求項５の支持具は、取着部において、挟持されたボルト体の側方に取付けられているので、配設体の荷重による支持具を回動させようとするモーメントは発生しない。   As a result, if the support part is attached to a place other than the above in the attachment part, if the load of the supported arrangement body is large, the upper and lower locking parts and the bolt body come into contact with each other. There is a possibility that a moment is generated to rotate the attachment body around the part, and the attachment body rotates and is detached from the bolt body. However, since the support tool according to the fifth aspect is attached to the side of the clamped bolt body at the attachment portion, a moment to rotate the support tool due to the load of the arrangement body does not occur.

請求項６のボルト体への取着体は、取着部が配設体を支持する支持部を備え、その支持部は、取着部において、挟持された前記ボルト体の軸心を通る側方であって該ボルト体の挿入方向と直交する側方である位置から該ボルト体の挿入開口側に所定距離離間した位置に取付けられている。即ち、支持部は、請求項５では、取着部においてボルト体の軸心を通る側方に取付けられているのに対して、請求項６では、ボルト体の軸心より挿入開口側にずれた位置に取付けられている。   The attachment body to the bolt body according to claim 6 includes a support portion in which the attachment portion supports the arrangement body, and the support portion is a side passing through an axis of the bolt body sandwiched in the attachment portion. It is attached to a position that is a predetermined distance away from the position that is the side that is orthogonal to the direction in which the bolt body is inserted and that is on the insertion opening side of the bolt body. That is, in the fifth aspect, the support portion is attached to the side passing through the axial center of the bolt body in the attachment portion, whereas in the sixth aspect, the support portion is displaced to the insertion opening side from the axial center of the bolt body. Is installed in a different position.

請求項７のボルト体への取着体は、取着部の側壁に、先端がボルト体の外面に側方から圧接されるビスが取付けられている。この場合、ビスは、取着部の両側壁に取付けてもよいし、いずれか一方の側壁のみに取付けてもよい。   In the attachment body to the bolt body according to the seventh aspect, a screw whose tip is pressed against the outer surface of the bolt body from the side is attached to the side wall of the attachment portion. In this case, the screws may be attached to both side walls of the attachment portion, or may be attached to only one of the side walls.

請求項８乃至請求項１２のナット体は、それぞれ、請求項１乃至請求項４及び請求項７の取着体における取着部と同様に構成されており、係止部がボルト体の螺子溝に係止してボルト体を挟持するとともに、ボルト体に取着された状態でこのボルト体を軸にナット体全体を回転することによってボルト体の軸方向に移動可能なものである。このナット体は、取着体の取着部に相当するものであるが、ボルト等の螺子溝に螺着されるナットとしての締付作用も有することから、取着部に相当するものを独立してナット体として構成したものである。   The nut bodies according to claims 8 to 12 are configured in the same manner as the attachment portions in the attachment bodies according to claims 1 to 4 and 7, respectively, and the locking portions are screw grooves of the bolt bodies. And the bolt body is clamped and moved in the axial direction of the bolt body by rotating the entire nut body around the bolt body while attached to the bolt body. This nut body corresponds to the attachment portion of the attachment body, but also has a tightening action as a nut screwed into a screw groove such as a bolt, so that the one corresponding to the attachment portion is independent. And configured as a nut body.

請求項１乃至請求項３の発明は、取着体が、一対の挟持片でボルト体を両側方から弾性的に挟持し、振れ止め部により取着部の振れが防止されてボルト体に取着されるものであるから、構造上、片手で把持し易い。また、構造上、ボルト体に安定して取着されるから、取着部は大きな弾性力を備える必要がない。これらの結果、大きな力を要することなく取着体を簡単にボルト体に取着することができる。   In the first to third aspects of the present invention, the mounting body elastically clamps the bolt body from both sides with a pair of clamping pieces, and the mounting portion is prevented from swinging by the steadying portion so that the mounting body can be attached to the bolt body. Since it is worn, it is easy to hold with one hand because of its structure. In addition, since the structure is stably attached to the bolt body, the attachment portion does not need to have a large elastic force. As a result, the attachment body can be easily attached to the bolt body without requiring a large force.

また、取着体は、ボルト体の軸方向の所望する位置に配置した後、そのまま側方に移動させて一対の挟持片で挟持し振れ止め部により振れを防止してボルト体に取着することができるから、ボルト体の所定位置に確実かつ正確に取着することができる。   Further, after the mounting body is disposed at a desired position in the axial direction of the bolt body, the mounting body is moved to the side as it is, and is clamped by a pair of clamping pieces, and is prevented from being shaken by the steadying portion and attached to the bolt body. Therefore, the bolt body can be securely and accurately attached to a predetermined position.

請求項４の発明は、取着体を単に側方からボルト体に強制的に押し付けるだけでボルト体に取着することができるから、取着体をボルト体に取着するに際し、挟持片をその弾性力に抗して開閉させる必要がなく、取着体の取着作業を極めて楽にかつ簡単に行なうことができる。   In the invention of claim 4, since the attachment body can be attached to the bolt body simply by forcibly pressing the attachment body from the side, the clamping piece is not attached when attaching the attachment body to the bolt body. It is not necessary to open and close against the elastic force, and the attachment work of the attachment body can be performed very easily and easily.

請求項５の発明は、支持部が、取着部において、挟持されたボルト体の軸心を通る側方であって、該ボルト体の挿入方向と直交する側方に取付けられているから、配設体の荷重による、係止部とボルト体との当接部を軸として取着体を回動させようとするモーメントは発生せず、したがって、支持部で支持される配設体の荷重が大きい場合でも、取着体がボルト体から抜脱するのをより確実に防止することができる。   In the invention of claim 5, the support portion is attached to the side that passes through the axis of the clamped bolt body in the attachment portion and is perpendicular to the insertion direction of the bolt body. No moment is generated by the load of the arrangement body to rotate the attachment body around the contact portion between the locking portion and the bolt body, and therefore the load of the arrangement body supported by the support section Even when is large, it can prevent more reliably that an attachment body removes from a bolt body.

請求項６の発明は、支持部が、取着部において、ボルト体の軸心を通る側方の位置から挿入開口側にずれた位置に取付けられている。これにより、支持部が例えば丸棒からなるフックで形成されている場合において、支持部に配設体の荷重が加わることによりフックの側面がボルト体の外面に当接し押付けられることがあったとしても、その当接箇所はボルト体の軸心を通る中心線からボルト体の挿入開口側に離間した位置にある。したがって、フックは配設体の荷重によってボルト体の外面を挿入開口側とは反対方向に押圧する、即ち離脱側とは反対方向に押圧することになるから、取着体がボルト体から抜脱するのをより確実に防止することができる。   In the invention of claim 6, the support portion is attached to the attachment portion at a position shifted from the side position passing through the axis of the bolt body toward the insertion opening. As a result, when the support portion is formed of a hook made of a round bar, for example, the side surface of the hook may come into contact with and be pressed against the outer surface of the bolt body by applying the load of the arrangement body to the support portion. However, the contact point is at a position spaced from the center line passing through the axis of the bolt body toward the insertion opening side of the bolt body. Therefore, the hook presses the outer surface of the bolt body in the direction opposite to the insertion opening side by the load of the arrangement body, that is, presses it in the direction opposite to the detachment side. It can prevent more reliably.

請求項７の発明は、取着部の側壁にビスが取付けられ、その先端はボルト体の外面に側方から圧接されるから、取着体をボルト体の所定位置に強固に固定することができ、取着体がボルト体の軸心を中心に回動するのを確実に防止できる。また、ビスの先端をボルト体の外面に圧接することにより、取着部の側壁はビスの突張りによる反力を受けて外方に拡開しようとし、つまりは、ボルト体の挿入空間が狭められ、一対の挟持片による挟持力が増すので、ボルト体からの取着体の抜脱防止効果を高めることができる。   According to the seventh aspect of the present invention, since the screw is attached to the side wall of the attachment portion and the tip thereof is pressed against the outer surface of the bolt body from the side, the attachment body can be firmly fixed to a predetermined position of the bolt body. It is possible to reliably prevent the attachment body from rotating about the axis of the bolt body. In addition, by pressing the tip of the screw against the outer surface of the bolt body, the side wall of the mounting part is subjected to reaction force due to the tension of the screw and tries to expand outward, that is, the space for inserting the bolt body is narrowed. Since the clamping force by the pair of clamping pieces is increased, the effect of preventing the attachment body from being detached from the bolt body can be enhanced.

請求項８の発明は、請求項１の取着体と同様に構成され、係止部がボルト体の螺子溝に係止し、ボルト体を軸にナット体を回転することによってボルト体の軸方向に移動可能なものであるから、ナット体をボルト体の軸方向の任意位置に側方からあてがった後ボルト体に対して回転させることにより、簡単にナットとしての締付作業を行なうことができる。したがって、一対のナット体で上下等の両側から鋼板等を挟み込んで締付けることにより、鋼板等をボルト体に取着したりする作業を簡単に行なうことができる。   The invention according to claim 8 is configured in the same manner as the attachment body according to claim 1, wherein the locking portion is locked in the screw groove of the bolt body, and the nut body is rotated about the bolt body as a shaft. Because the nut body can be moved in the direction, it can be easily tightened as a nut by rotating the nut body from the side to an arbitrary position in the axial direction of the bolt body and then rotating it with respect to the bolt body. it can. Therefore, the work of attaching the steel plate or the like to the bolt body can be easily performed by sandwiching and tightening the steel plate or the like from both the upper and lower sides with a pair of nut bodies.

〈ボルト体への取着体〉
以下、まず、本発明の実施形態のボルト体への取着体を図に基づいて説明する。なお、本実施形態の説明において、上下方向とは、図１の吊りボルトの軸方向を意味する。
図１乃至図３において、取着体１は、ボルト体としての吊りボルト４１に取着されるものであり、吊りボルト４１に取着される取着部１１と、取着部１１に取付けられ、ケーブル４２を支持する支持部３１とを備えている。吊りボルト４１は建物の二重天井に垂設されている。取着部１１は、左右両側に配設された一対の側壁１３，１４と、吊りボルト４１の挟持状態における振れを防止する振れ止め部２３とを備えている。更に、一対の側壁１３，１４のそれぞれの上端部及び下端部からは水平方向に挟持片が延設されており、各挟持片には、反対側から吊りボルト４１に当接して係止する係止部１９が設けられている。以下、各構成部材について説明する。 <Attached body to bolt body>
Hereinafter, first, the attachment body to the bolt body of the embodiment of the present invention will be described based on the drawings. In the description of the present embodiment, the vertical direction means the axial direction of the suspension bolt in FIG.
1 to 3, the attachment body 1 is attached to a suspension bolt 41 as a bolt body, and is attached to the attachment portion 11 and the attachment portion 11 attached to the suspension bolt 41. And a support portion 31 that supports the cable 42. The suspension bolt 41 is suspended from the double ceiling of the building. The attachment portion 11 includes a pair of side walls 13 and 14 disposed on both the left and right sides, and a steady stop portion 23 that prevents the suspension bolt 41 from swinging in the clamping state. Furthermore, a holding piece extends horizontally from the upper end and the lower end of each of the pair of side walls 13 and 14, and each holding piece comes into contact with and engages the suspension bolt 41 from the opposite side. A stop 19 is provided. Hereinafter, each component will be described.

前記取着部１１は、所定の弾性を有する鋼材等の金属板材からなり、これをプレス加工等により折曲して、中間の連結板部１５の左右両側それぞれにコ字板部材が一体に形成された形状となっている。このコ字板部材は、具体的には、連結板部１５の左右両側に一対の側壁１３，１４が一体に設けられ、更に、各側壁から水平方向に延出する挟持片が一体に設けられたものとなっている。一対の側壁１３，１４は、前記挟持片を延設させる基板となる部分であるとともに、取着体１を吊りボルト４１に取着した後取り外す際に、左右から挟圧して取り外す操作を行なう部分でもある。左側の側壁１３の上端部からは上側挟持片１６が水平方向に延設され、下端部からは下側挟持片１７が延設されている。また、右側の側壁１４の上端部からは上側挟持片１６が水平方向に延設され、下端部からは下側挟持片１７が延設されている。これらの上側挟持片１６及び下側挟持片１７は、それぞれ、各側壁から吊りボルト４１を超えた反対側まで延びている。左側の側壁１３の高さは右側の側壁１４より小さく形成されている。したがって、側壁１３の上側挟持片１６と側壁１４の上側挟持片１６とは、間隔をおいて上下方向に重なり合った状態にある。同様に、側壁１３の下側挟持片１７と側壁１４の下側挟持片１７とは、間隔をおいて上下方向に重なり合った状態にある。即ち、取着部１１は、左右一対の挟持片を上下に二組備えており、計４個の挟持片は、吊りボルト４１の反対側まで延びていて、互いに高さ方向つまり吊りボルト４１の軸方向において異なる位置に配設されている。   The attachment portion 11 is made of a metal plate material such as a steel material having a predetermined elasticity, and is bent by pressing or the like so that a U-shaped plate member is integrally formed on each of the left and right sides of the intermediate connection plate portion 15. It has become a shape. Specifically, the U-shaped plate member is integrally provided with a pair of side walls 13, 14 on both the left and right sides of the connecting plate portion 15, and is further provided with a holding piece extending horizontally from each side wall. It has become. The pair of side walls 13 and 14 is a portion that becomes a substrate on which the clamping piece is extended, and a portion that performs an operation of squeezing from the left and right when removing the attachment body 1 after attaching it to the suspension bolt 41. But there is. An upper clamping piece 16 extends horizontally from the upper end of the left side wall 13, and a lower clamping piece 17 extends from the lower end. Further, an upper clamping piece 16 extends horizontally from the upper end of the right side wall 14, and a lower clamping piece 17 extends from the lower end. These upper clamping piece 16 and lower clamping piece 17 each extend from each side wall to the opposite side beyond the suspension bolt 41. The height of the left side wall 13 is smaller than that of the right side wall 14. Therefore, the upper clamping piece 16 of the side wall 13 and the upper clamping piece 16 of the side wall 14 are in a state of being overlapped in the vertical direction with a space therebetween. Similarly, the lower holding piece 17 of the side wall 13 and the lower holding piece 17 of the side wall 14 are in a state of being overlapped in the vertical direction with a space therebetween. That is, the attachment portion 11 includes two pairs of left and right clamping pieces, and a total of four clamping pieces extend to the opposite side of the suspension bolt 41, and are in the height direction, that is, the suspension bolt 41. They are arranged at different positions in the axial direction.

更に、上側挟持片１６及び下側挟持片１７には、図３に示すように、吊りボルト４１と対向する側の端縁部２２に切欠孔１８を形成することにより、外部と連通して切欠開口２０から吊りボルト４１が挿入され収容される挿入空間２１が形成されているとともに、切欠孔１８において吊りボルト４１の外面と当接する部分には、吊りボルト４１の螺子溝と係止する係止部１９が形成されている。係止部１９は、吊りボルト４１の反対側から吊りボルト４１に係止する。ここで、取着部１１は鋼板等で形成されているので、係止部１９は吊りボルト４１の螺子溝内に嵌入するとともに、取着体１は吊りボルト４１に対して回転させることにより吊りボルト４１の軸方向に移動させることができる。   Further, as shown in FIG. 3, the upper clamping piece 16 and the lower clamping piece 17 are notched in communication with the outside by forming a notch hole 18 in the end edge portion 22 on the side facing the suspension bolt 41. An insertion space 21 in which the suspension bolt 41 is inserted and accommodated from the opening 20 is formed, and a portion that contacts the outer surface of the suspension bolt 41 in the cutout hole 18 is engaged with a screw groove of the suspension bolt 41. A portion 19 is formed. The locking part 19 is locked to the suspension bolt 41 from the opposite side of the suspension bolt 41. Here, since the attachment portion 11 is formed of a steel plate or the like, the locking portion 19 is fitted into the screw groove of the suspension bolt 41 and the attachment body 1 is suspended by being rotated with respect to the suspension bolt 41. The bolt 41 can be moved in the axial direction.

側壁１３側の挟持片の挿入空間２１と側壁１４側の挟持片の挿入空間２１とは、上下方向即ちボルト体の軸方向から見て、図５(a)に示すように、一部が互いに重なり合っている。図５(a)において、斜線部分は左右両挿入空間２１の重なり部分２１ａを示す。また、一部が重なり合った状態において、側壁１３側の挟持片の挿入空間２１の切欠開口２０及び側壁１４側の挟持片の挿入空間２１の切欠開口２０は外部に連通しているとともに、各切欠開口２０の縁部はアール状または直線状に面取り加工が施されている。この面取り加工部分は吊りボルト４１を挿入空間２１内に導く案内部として機能する。したがって、取着部１１の挿入開口側１２から取着体１を吊りボルト４１に向けて押し付けることにより、吊りボルト４１を前記案内部によって両切欠開口２０に導き、両切欠開口２０から挿入し移動させることができるようになっている。そして、各挟持片は、側壁１３側の挟持片の挿入空間２１と側壁１４側の挟持片の挿入空間２１との重なり部分２１ａを左右に拡張しつつ吊りボルト４１を両挿入空間２１に収容し、両係止部１９を吊りボルト４１の螺子溝に係止させることができるようになっている。なお、図５及び以下の図６、図８乃至図１３においては、支持部３１の図示は省略してある。   As shown in FIG. 5 (a), the insertion space 21 of the sandwiching piece on the side wall 13 side and the insertion space 21 of the clamping piece on the side wall 14 side are viewed from the vertical direction, that is, the axial direction of the bolt body. They are overlapping. In FIG. 5 (a), the hatched portion indicates an overlapping portion 21 a of the left and right insertion spaces 21. Further, in a state where the portions overlap each other, the notch opening 20 in the insertion space 21 for the sandwiching piece on the side of the side wall 13 and the notch opening 20 in the insertion space 21 for the sandwiching piece on the side of the side wall 14 communicate with the outside. The edge of the opening 20 is chamfered in a round shape or a straight shape. This chamfered portion functions as a guide portion that guides the suspension bolt 41 into the insertion space 21. Therefore, by pressing the attachment body 1 toward the suspension bolt 41 from the insertion opening side 12 of the attachment portion 11, the suspension bolt 41 is guided to the both notch openings 20 by the guide portion, and is inserted and moved from both the notch openings 20. It can be made to. Each sandwiching piece accommodates the suspension bolt 41 in both the insertion spaces 21 while extending an overlapping portion 21a between the sandwiching piece insertion space 21 on the side wall 13 side and the insertion space 21 on the side wall 14 side. Both the locking portions 19 can be locked in the screw grooves of the suspension bolt 41. In FIG. 5 and the following FIGS. 6 and 8 to 13, the support portion 31 is not shown.

各係止部１９は、吊りボルト４１の軸方向の異なる位置にあって、吊りボルト４１が挿入空間２１の内部に収容されると、図６に示すように、上から側壁１４の上側挟持片１６の係止部１９、次いで、側壁１３の上側挟持片１６の係止部１９、更に、側壁１３の下側挟持片１７の係止部１９、そして、側壁１４の下側挟持片１７の係止部１９の順に吊りボルト４１の外面に当接するようになっている。つまり、各係止部１９は、吊りボルト４１に対して、上から、左側、右側、右側、左側の順に交互に異なる側から図６の黒丸で示す計４箇所で当接するようになっている。   Each locking portion 19 is located at a different position in the axial direction of the suspension bolt 41, and when the suspension bolt 41 is accommodated in the insertion space 21, as shown in FIG. 16, the locking portion 19 of the upper clamping piece 16 of the side wall 13, the locking portion 19 of the lower clamping piece 17 of the side wall 13, and the lower clamping piece 17 of the side wall 14. It comes to contact | abut to the outer surface of the suspension bolt 41 in order of the stop part 19. As shown in FIG. In other words, each locking portion 19 comes into contact with the suspension bolt 41 at a total of four locations indicated by black circles in FIG. 6 from the sides that are alternately different from the top, the left side, the right side, the right side, and the left side. .

更に、各挟持片において切欠孔１８により形成された挿入空間２１は、上側挟持片１６の挿入空間２１と下側挟持片１７の挿入空間２１とで形状が異なっている。上側挟持片１６の挿入空間２１の周縁２１ｂは、図３(a)に示すように、上側挟持片１６のほぼ中央部に楕円が形成され、その楕円から切欠開口２０に至る一方の周縁２１ｂは直線２１ｃに形成されている。これに対して、下側挟持片１７の挿入空間２１の周縁２１ｂは、図３(d)に示すように、下側挟持片１７のほぼ中央部に円が設けられ、その円から切欠開口２０に至る一方の周縁２１ｂは傾斜線２１ｄに形成されている。このように少なくとも下側挟持片１７の挿入空間２１の周縁２１ｂを上記形状とした理由は後述する。   Furthermore, the insertion space 21 formed by the notch hole 18 in each clamping piece is different in shape between the insertion space 21 of the upper clamping piece 16 and the insertion space 21 of the lower clamping piece 17. As shown in FIG. 3A, the peripheral edge 21b of the insertion space 21 of the upper clamping piece 16 is formed with an ellipse at substantially the center of the upper clamping piece 16, and one peripheral edge 21b extending from the ellipse to the notch opening 20 is It is formed in a straight line 21c. On the other hand, the peripheral edge 21b of the insertion space 21 of the lower holding piece 17 is provided with a circle at substantially the center of the lower holding piece 17, as shown in FIG. One peripheral edge 21b extending to is formed on an inclined line 21d. The reason why at least the peripheral edge 21b of the insertion space 21 of the lower sandwiching piece 17 is thus shaped will be described later.

このような取着部１１の構成において、左側の側壁１３の上側挟持片１６の係止部１９及び右側の側壁１４の上側挟持片１６の係止部１９は、取着部１１の上部側において吊りボルト４１を両側方から弾性的に挟持し、側壁１３の下側挟持片１７の係止部１９及び側壁１４の下側挟持片１７の係止部１９は、取着部１１の下部側において吊りボルト４１を両側方から弾性的に挟持するものであるが、同時に、取着部１１の下部側の下側挟持片１７の係止部１９は、吊りボルト４１に係止することにより、一対の上側挟持片１６，１６による挟持状態において取着部１１の下部側が振れるのを防止する振れ止め部２３としても機能し、また、取着部１１の上部側の上側挟持片１６の係止部１９は、吊りボルト４１に係止することにより、一対の下側挟持片１７，１７による挟持状態において取着部１１の上部側が振れるのを防止する振れ止め部２３としても機能する。   In such a configuration of the attachment part 11, the engagement part 19 of the upper clamping piece 16 of the left side wall 13 and the engagement part 19 of the upper clamping piece 16 of the right side wall 14 are arranged on the upper side of the attachment part 11. The suspension bolt 41 is elastically clamped from both sides, and the locking portion 19 of the lower clamping piece 17 of the side wall 13 and the locking portion 19 of the lower clamping piece 17 of the side wall 14 are located on the lower side of the attachment portion 11. The suspension bolt 41 is elastically clamped from both sides. At the same time, the locking portion 19 of the lower clamping piece 17 on the lower side of the attachment portion 11 is locked to the suspension bolt 41 so that It functions also as a steady stop 23 that prevents the lower side of the attachment portion 11 from swinging in the state of being sandwiched by the upper sandwiching pieces 16, 16, and the locking portion of the upper sandwiching piece 16 on the upper side of the attachment portion 11. 19 is engaged with the suspension bolt 41 so that a pair of Also functions as a stop 23 shake to prevent the upper side of the mounting portion 11 is deflected in the clamped state by the side holding pieces 17, 17.

これについて付説すれば、取着部１１は、上部側の左右一対の上側挟持片１６，１６によって吊りボルト４１を上部側において挟持するが、仮に、この一対の上側挟持片１６，１６のみで挟持するとすれば、下部側において吊りボルト４１に当接、係止する部分がないため、取着部１１は下部側が吊りボルト４１に対して左右に振れて傾いてしまう。しかし、本実施形態の取着部１１の下部側には左右一対の下側挟持片１７，１７が設けられているので、そのうちのいずれか、図６においては右側の側壁１４の下側挟持片１７の係止部１９が吊りボルト４１に係止して前記振れを防止することができる。このことは、上部側の上側挟持片１６の係止部１９を振れ止め部２３とする場合についても同様である。このようなことで、上部側の上側挟持片１６の係止部１９及び下部側の下側挟持片１７の係止部１９は、挟持態様により、請求項の振れ止め部にも該当する。   If it attaches about this, although the attachment part 11 clamps the suspending bolt 41 in the upper part side by the pair of left and right upper clamping pieces 16 and 16 on the upper side, tentatively, only by this pair of upper clamping parts 16 and 16. If it is clamped, there is no portion that contacts and locks the suspension bolt 41 on the lower side, so that the attachment portion 11 is tilted with the lower side swinging left and right with respect to the suspension bolt 41. However, since a pair of left and right lower holding pieces 17, 17 are provided on the lower side of the attachment portion 11 of the present embodiment, one of them, the lower holding piece of the right side wall 14 in FIG. The 17 locking portions 19 can be locked to the suspension bolt 41 to prevent the shake. The same applies to the case where the locking portion 19 of the upper clamping piece 16 on the upper side is used as the steadying portion 23. Thus, the locking portion 19 of the upper holding piece 16 on the upper side and the locking portion 19 of the lower holding piece 17 on the lower side also correspond to the steady portion of the claims depending on the holding mode.

したがって、取着部１１は、一対の挟持片を吊りボルト４１の軸方向に二組備え、そのうちの例えば下側挟持片１７の係止部１９は振れ止め部２３を構成するから、この取着体１は、請求項１、請求項３、請求項８及び請求項１０の態様に相当する。また、取着部１１は、係止部１９が、上から、少なくとも、左側、右側、左側の順に交互に異なる側から３箇所で吊りボルト４１に当接、係止するものでもあり、そのうちの例えば下側挟持片１７の係止部１９は振れ止め部２３を構成するから、この取着体１は、請求項１、請求項２、請求項８及び請求項９の態様にも相当する。   Therefore, the attachment part 11 includes two pairs of clamping pieces in the axial direction of the suspension bolt 41, and for example, the locking part 19 of the lower clamping piece 17 constitutes the steadying part 23. The body 1 corresponds to the aspects of claims 1, 3, 8, and 10. In addition, the attachment portion 11 is also one in which the locking portion 19 abuts and locks the suspension bolt 41 at three locations from the top, which are alternately at least on the left side, the right side, and the left side, from among them. For example, since the locking portion 19 of the lower holding piece 17 constitutes the steadying portion 23, the attachment 1 corresponds to the aspects of the first, second, eighth, and ninth aspects.

次に、ケーブル４２を支持する支持部３１は、図１及び図２に示すように、ケーブル４２の大きさに対応して、上部が開口する略円弧状に形成されている。支持部３１は、図４(a)に示すように、取着部１１の左右両側壁において、挟持された吊りボルト４１の軸心Ｏを通る側方であって、白抜き矢印で示す吊りボルト４１の相対的な挿入方向とは直交する側方に一対取付けられている。別言すれば、支持部３１は、取着部１１の左右両側壁において、挟持された吊りボルト４１の軸心Ｏを横切り、吊りボルト４１の挿入方向と直交する一点鎖線で示す平面Ｐと交わる図４(b)の左右一対の上下方向の交線Ｌ上に取付けられている。この位置に支持部３１を取付けた理由は後述する。なお、図４(a)においては、支持部３１は、取着部１１への取付部分のみを示し、他の部分は図示を省略してある。   Next, as shown in FIG. 1 and FIG. 2, the support portion 31 that supports the cable 42 is formed in a substantially arc shape whose upper portion is open corresponding to the size of the cable 42. As shown in FIG. 4 (a), the support portion 31 is a side that passes through the axial center O of the sandwiched suspension bolt 41 on the left and right side walls of the attachment portion 11, and is a suspension bolt indicated by a white arrow. A pair of 41 is attached to the side orthogonal to the relative insertion direction. In other words, the support portion 31 intersects the plane P indicated by a one-dot chain line orthogonal to the insertion direction of the suspension bolt 41 across the axis O of the sandwiched suspension bolt 41 on the left and right side walls of the attachment portion 11. They are attached on a pair of left and right vertical lines L in FIG. The reason why the support portion 31 is attached at this position will be described later. In FIG. 4 (a), the support portion 31 shows only the attachment portion to the attachment portion 11, and the other portions are not shown.

支持部３１は、丸鋼等を円弧状に湾曲させて形成され、取着部１１への取付部分においては、丸鋼等をプレス加工により偏平化してこの部分にリベット３２を打ち込むことによって取付けられている。円弧状の湾曲部分はリベット３２の取付部分から垂直下方に延出し、ケーブル４２が載置される載置部３３が形成されている。なお、支持部３１は、図２に示すように、吊りボルト４１側の湾曲部が吊りボルト４１に当接する状態に取付けられるのが望ましい。支持部３１がケーブル４２の荷重によって傾いたり、その荷重によって円弧が伸ばされて載置部３３の上部開口が広がるのを吊りボルト４１で支持して防止できるからである。また、図７に基づいて後述するように、支持部３１にケーブル４２の荷重が加わると、吊りボルト４１を軸とする白抜き矢印方向のモーメントが発生し、支持部３１はモーメントの方向に回動しようとする。その結果、一対の下側挟持片１７，１７は矢印のように互いに近接する方向に閉じられ、一対の下側挟持片１７，１７の挿入空間２１の重なり部分２１ａは、左右に拡張しようとするので、その分挟持力は弱まり、取着部１１は吊りボルト４１から抜脱し易くなる。そこで、支持部３１の吊りボルト４１側の湾曲部を吊りボルト４１に当接する状態に取付ければ、ケーブル４２の荷重を吊りボルト４１によって支持させ、支持部３１の回動を抑えて一対の下側挟持片１７，１７の挿入空間２１の重なり部分２１ａの拡張を防ぐことができるからである。   The support portion 31 is formed by curving round steel or the like in an arc shape, and is attached to the attachment portion 11 by flattening the round steel or the like by pressing and driving a rivet 32 into this portion. ing. The arcuate curved portion extends vertically downward from the attachment portion of the rivet 32, and a placement portion 33 on which the cable 42 is placed is formed. As shown in FIG. 2, the support portion 31 is preferably attached so that the curved portion on the suspension bolt 41 side is in contact with the suspension bolt 41. This is because the suspension bolt 41 can support and prevent the support portion 31 from being inclined due to the load of the cable 42 and the arc opening being extended by the load to expand the upper opening of the placement portion 33. As will be described later with reference to FIG. 7, when a load of the cable 42 is applied to the support portion 31, a moment in the direction of a white arrow with the suspension bolt 41 as an axis is generated, and the support portion 31 rotates in the direction of the moment. Try to move. As a result, the pair of lower sandwiching pieces 17 and 17 are closed in directions close to each other as indicated by arrows, and the overlapping portion 21a of the insertion space 21 of the pair of lower sandwiching pieces 17 and 17 tends to expand to the left and right. Therefore, the clamping force is weakened by that amount, and the attachment portion 11 is easily removed from the suspension bolt 41. Therefore, if the curved portion on the side of the suspension bolt 41 of the support portion 31 is attached in a state where it abuts on the suspension bolt 41, the load of the cable 42 is supported by the suspension bolt 41, and the rotation of the support portion 31 is suppressed and a pair of lower This is because it is possible to prevent the overlapping portion 21a of the insertion space 21 of the side clamping pieces 17 and 17 from being expanded.

次に、上記のように構成された取着体１を吊りボルト４１に取着する方法を図５に基づいて説明する。
まず、図５(a)に示すように、各挟持片の切欠開口２０が吊りボルト４１と対峙する状態で取着体１を吊りボルト４１の軸方向の所望する位置に配置する。次いで、取着体１をそのまま水平方向に移動させて、一対の挟持片の切欠開口２０側から吊りボルト４１に向けて強制的に押し込む。このとき、一対の上側挟持片１６，１６等は、図５(b)の矢印で示すように、弾性力に抗して互いに閉じる方向に近接移動する。これに伴い、一対の係止部１９，１９は、反対側から吊りボルト４１に係止するものであるから、逆に一旦は互いに離間し左右に拡開する。そして、一対の挿入空間２１の重なり部分２１ａは左右に拡張し、吊りボルト４１は切欠開口２０を通過可能となる。そこで、吊りボルト４１が切欠開口２０を通過すると、各挟持片は弾性復帰力により上記と反対側に僅かに移動して互いに僅かに離間するとともに、一対の係止部１９，１９は逆に互いに僅かに近接する方向に移動する。そして、吊りボルト４１は、４箇所全ての挿入空間２１内に押し込まれ収容される。収容後は、図１及び図２において、一対の上側挟持片１６，１６は吊りボルト４１を挟持し、一対の下側挟持片１７，１７は吊りボルトを挟持して取着部１１の下部が吊りボルト４１に対して振れて傾くのを防止する振れ止めとして作用し、取着体１の取着は完了する。取着後は図４(a)の状態となる。 Next, a method for attaching the attachment body 1 configured as described above to the suspension bolt 41 will be described with reference to FIG.
First, as shown in FIG. 5A, the attachment body 1 is disposed at a desired position in the axial direction of the suspension bolt 41 with the notch opening 20 of each sandwiching piece facing the suspension bolt 41. Next, the attachment body 1 is moved in the horizontal direction as it is, and is forcedly pushed toward the suspension bolt 41 from the notch opening 20 side of the pair of holding pieces. At this time, the pair of upper clamping pieces 16, 16 and the like move close to each other in the direction of closing each other against the elastic force, as indicated by the arrows in FIG. Accordingly, the pair of locking portions 19 and 19 are locked to the suspension bolt 41 from the opposite side, and conversely, they are once separated from each other and expanded to the left and right. And the overlapping part 21a of a pair of insertion space 21 is extended right and left, and the suspension bolt 41 can pass the notch opening 20. FIG. Therefore, when the suspension bolt 41 passes through the notch opening 20, each clamping piece is slightly moved to the opposite side by the elastic restoring force and slightly separated from each other, and the pair of locking portions 19 and 19 are opposite to each other. Move in a slightly closer direction. Then, the suspension bolt 41 is pushed into and accommodated in all the four insertion spaces 21. 1 and 2, the pair of upper holding pieces 16, 16 holds the suspension bolt 41, and the pair of lower holding pieces 17, 17 holds the suspension bolt so that the lower portion of the attachment portion 11 is It acts as a steady rest that prevents the suspension bolt 41 from swinging and tilting, and the attachment of the attachment 1 is completed. After attachment, the state shown in FIG.

次に、本実施形態の取着体１の作用を説明する。
取着部１１は、両側に配設された一対の側壁１３，１４のそれぞれから吊りボルト４１の反対側まで延出する一対の上側挟持片１６，１６を備え、各上側挟持片１６に吊りボルト４１に係止する係止部１９が設けられており、一対の上側挟持片１６，１６は、互いに近接、縮閉する一方、挿入空間２１の重なり部分２１ａは吊りボルト４１を挿入可能に拡開し、切欠開口２０から吊りボルト４１が挿入された後は、弾性復帰して吊りボルト４１に反対側から係止することにより、吊りボルト４１を両側方から挟持する。更に、取着部１１は、挟持状態における振れを防止する、下側挟持片１７の係止部１９からなる振れ止め部２３を備えている。したがって、取着体１は、一対の上側挟持片１６，１６による両側方からの挟持と下側挟持片１７の振れ止め部２３による振れ止めとにより吊りボルト４１に対して振れることなく一定の垂直姿勢に安定して保持され取着される。 Next, the effect | action of the attachment body 1 of this embodiment is demonstrated.
The attachment portion 11 includes a pair of upper holding pieces 16 and 16 extending from the respective side walls 13 and 14 disposed on both sides to the opposite side of the hanging bolt 41, and the upper holding pieces 16 are provided with a hanging bolt. A pair of upper clamping pieces 16 and 16 are close to each other and contracted while the overlapping portion 21a of the insertion space 21 is expanded so that the suspension bolt 41 can be inserted. Then, after the suspension bolt 41 is inserted from the notch opening 20, the suspension bolt 41 is clamped from both sides by elastic recovery and locking to the suspension bolt 41 from the opposite side. Furthermore, the attachment part 11 is provided with the steadying part 23 which consists of the latching | locking part 19 of the lower side clamping piece 17 which prevents the shaking in a clamping state. Therefore, the attachment body 1 is fixed vertically without swinging with respect to the suspension bolt 41 by the clamping from both sides by the pair of upper clamping pieces 16 and 16 and the steadying by the steadying portion 23 of the lower clamping piece 17. It is stably held and attached to the posture.

そして、特に、取着体１は、左右一対の上側挟持片１６，１６で吊りボルト４１を両側方から弾性的に挟持してこれに取着される構造となっているから、取着の際、片手で把持し易い。また、取着体１は、構造上、吊りボルト４１に安定して取着されるから、取着部１１は大きな弾性力を備える必要はない。これらにより、大きな力を要することなく取着体１を作業性良く簡単にボルト体に取着することができる。   In particular, the attachment body 1 has a structure in which the suspension bolt 41 is elastically clamped from both sides by a pair of left and right upper clamping pieces 16 and 16 and attached thereto. Easy to hold with one hand. Moreover, since the attachment body 1 is structurally attached to the suspension bolt 41, the attachment portion 11 does not need to have a large elastic force. Thus, the attachment body 1 can be easily attached to the bolt body with good workability without requiring a large force.

また、取着体１は、吊りボルト４１の軸方向の所望する位置に配置した後、そのまま側方に移動させて一対の挟持片で挟持するだけで吊りボルト４１に取着されるから、吊りボルト４１の所定位置に簡単に確実かつ正確に取着することができる。   Further, since the attachment body 1 is disposed at a desired position in the axial direction of the suspension bolt 41 and then is moved to the side as it is and is attached to the suspension bolt 41 simply by being sandwiched by a pair of sandwiching pieces, The bolt 41 can be easily and reliably attached to a predetermined position.

更に、各挟持片の挿入空間２１は、対向する他側の挟持片の挿入空間２１との間で、一部が吊りボルト４１の軸方向から見て互いに重なり合っているから、外部に連通している切欠開口２０から吊りボルト４１を挿入するようにして、取着体１を単に側方から吊りボルト４１に強制的に押し込むだけで、一対の係止部１９，１９は拡開し、重なり部分２１ａは拡張して、各係止部１９内に吊りボルト４１を収容させて係止させることができる。したがって、取着体１を吊りボルト４１に取着する際に、一対の係止部１９，１９を取着部１１の弾性力に抗して拡開させつつ吊りボルト４１を挿入する必要がなく、取着体１の取着作業を極めて楽にかつ簡単に行なうことができる。   Further, the insertion space 21 of each clamping piece partially overlaps the insertion space 21 of the other clamping piece on the other side as viewed from the axial direction of the suspension bolt 41, so that it communicates with the outside. When the suspension bolt 41 is inserted through the cutout opening 20 and the attachment body 1 is simply forcedly pushed into the suspension bolt 41 from the side, the pair of locking portions 19 and 19 are expanded, and the overlapping portions 21a can be expanded and the suspension bolts 41 can be accommodated in the locking portions 19 and locked. Therefore, when attaching the attachment body 1 to the suspension bolt 41, there is no need to insert the suspension bolt 41 while expanding the pair of locking portions 19, 19 against the elastic force of the attachment portion 11. The attachment work of the attachment body 1 can be performed very easily and easily.

そして、支持部３１は、取着部１１の側面において、挟持された吊りボルト４１の側方であって、挿入方向と直交する側方に取付けられているから、支持部３１で支持されるケーブル４２の荷重が大きい場合でも、取着体１が吊りボルト４１から抜脱するのをより確実に防止することができる。   And since the support part 31 is attached to the side of the attachment part 11 on the side of the sandwiched suspension bolt 41 and perpendicular to the insertion direction, the cable supported by the support part 31 Even when the load 42 is large, it is possible to more reliably prevent the attachment body 1 from being detached from the suspension bolt 41.

これについて説明すれば、仮に、支持部３１が取着部１１において上記以外の箇所に取付けられている場合、例えば、図４の二点鎖線で示したように、取着部１１の側面であって背面の連結板部１５寄りの箇所に取付けられている場合は、図４(b)に示すように、ケーブル４２の荷重によって取着部１１の下側挟持片１７と吊りボルト４１との当接部Ｔを軸とする白抜き矢印方向のモーメントが発生する。このため、支持されるケーブル４２の荷重が大きいと、取着体１は取着部１１の上部が前記吊りボルト４１との当接部Ｔを軸に図４(b)の二点鎖線矢印の方向に回動して吊りボルト４１から抜脱する虞が生ずる。   For example, if the support portion 31 is attached to a place other than the above in the attachment portion 11, for example, as shown by a two-dot chain line in FIG. 4, it is the side surface of the attachment portion 11. 4B, when the cable is attached to the rear side of the connecting plate portion 15, the contact between the lower holding piece 17 of the attachment portion 11 and the suspension bolt 41 is caused by the load of the cable 42, as shown in FIG. A moment in the direction of a white arrow with the contact portion T as an axis is generated. For this reason, when the load of the cable 42 to be supported is large, the attachment body 1 has an upper portion of the attachment portion 11 as shown by a two-dot chain line arrow in FIG. There is a possibility that the suspension bolt 41 may be removed from the suspension bolt 41 by rotating in the direction.

しかし、本実施形態の支持部３１は、上述のように、取着部１１の側面において、挟持された吊りボルト４１の軸心Ｏの側方に取付けられているので、ケーブル４２の荷重によって吊りボルト４１との当接部Ｔを軸に取着体１を回動させようとするモーメントは発生しない。したがって、支持部３１で支持されるケーブル４２の荷重が大きい場合でも、取着体１が吊りボルト４１から抜脱するのをより確実に防止することができる。   However, since the support portion 31 of the present embodiment is attached to the side of the axis O of the clamped suspension bolt 41 on the side surface of the attachment portion 11 as described above, the support portion 31 is suspended by the load of the cable 42. No moment is generated to rotate the attachment body 1 around the contact portion T with the bolt 41 as an axis. Therefore, even when the load of the cable 42 supported by the support portion 31 is large, the attachment body 1 can be more reliably prevented from being detached from the suspension bolt 41.

加えて、下部側の下側挟持片１７の挿入空間２１の周縁２１ｂは、図３(d)に示すように、中央部の円から切欠開口２０に至る一方が傾斜線２１ｄに形成されている。これにより、下部側の下側挟持片１７の係止部１９は吊りボルト４１との係止が解除され難いものとなっている。   In addition, as shown in FIG. 3D, the peripheral edge 21b of the insertion space 21 of the lower holding piece 17 on the lower side is formed with an inclined line 21d from the circle at the center to the cutout opening 20. . Thereby, the latching | locking part 19 of the lower side clamping piece 17 of the lower side becomes a thing which cannot be easily cancelled | released with the suspension bolt 41. FIG.

これについて説明すれば、図７に示すように、支持部３１にケーブル４２の荷重が加わると、吊りボルト４１を軸とする白抜き矢印方向のモーメントが発生する。このため、取着部１１は両側方から圧縮されて僅かに弾性変形し、一対の下側挟持片１７，１７は矢印のように互いに近接する方向に閉じられようとし、逆に一対の上側挟持片１６，１６は矢印のように互いに離間する方向に拡開しようとする。それに伴い、図示しないが、一対の下側挟持片１７，１７の挿入空間２１の重なり部分２１ａは、左右に拡張しようとするので、その分挟持力は弱まり、取着部１１は吊りボルト４１から抜脱し易くなる。その一方、一対の上側挟持片１６，１６の挿入空間２１の重なり部分２１ａは、逆に、縮小しようとするので、その分挟持力は強まり、取着部１１は吊りボルト４１から抜脱し難くなる。   If this is demonstrated, as shown in FIG. 7, when the load of the cable 42 is added to the support part 31, the moment of the white arrow direction centering on the suspension bolt 41 will generate | occur | produce. For this reason, the attachment part 11 is compressed from both sides and slightly elastically deformed, and the pair of lower clamping pieces 17 and 17 tend to be closed in directions close to each other as indicated by arrows, and conversely, the pair of upper clamping parts The pieces 16 and 16 try to expand in a direction away from each other as shown by arrows. Accordingly, although not shown, since the overlapping portion 21a of the insertion space 21 of the pair of lower holding pieces 17 and 17 tends to expand to the left and right, the holding force is reduced accordingly, and the attachment portion 11 is removed from the suspension bolt 41. It becomes easy to pull out. On the other hand, since the overlapping portion 21a of the insertion space 21 of the pair of upper clamping pieces 16 and 16 tends to shrink, the clamping force is increased accordingly, and the attachment portion 11 is difficult to be removed from the suspension bolt 41. .

そこで、抜脱し易い下側挟持片１７の挿入空間２１の周縁２１ｂについては、一方を傾斜線２１ｄに形成したのである。即ち、傾斜線２１ｄとすれば、吊りボルト４１の外面は傾斜線２１ｄの周縁２１ｂと当接することにより外れ難くなるのである。なお、取着体１を吊りボルト４１から取り外すときは、吊りボルト４１の外面を傾斜線２１ｄの周縁２１ｂに沿うようにして相対的に移動させつつ下側挟持片１７の挿入空間２１から抜き出す。   Therefore, one of the peripheral edges 21b of the insertion space 21 of the lower holding piece 17 that can be easily removed is formed on the inclined line 21d. That is, if the inclined line 21d is used, the outer surface of the suspension bolt 41 is less likely to come off by coming into contact with the peripheral edge 21b of the inclined line 21d. In addition, when removing the attachment body 1 from the suspension bolt 41, the outer surface of the suspension bolt 41 is extracted from the insertion space 21 of the lower clamping piece 17 while relatively moving along the peripheral edge 21b of the inclined line 21d.

一方、上側挟持片１６の係止部１９は、上述のように、下側挟持片１７の挿入空間２１と比較して抜脱する虞は小さいので、吊りボルト４１への押し込み時の作業性を重視して、吊りボルト４１が円滑に挿入空間２１内に導かれるよう、図３(a)に示すように、中央部の楕円から切欠開口２０に至る一方の周縁２１ｂを直線２１ｃに形成している。但し、上側挟持片１６の挿入空間２１の周縁２１ｂについても、下側挟持片１７の係止部１９と同様の形状に形成してもよい。   On the other hand, as described above, the locking portion 19 of the upper clamping piece 16 is less likely to be removed than the insertion space 21 of the lower clamping piece 17, so that the workability at the time of pushing into the suspension bolt 41 is improved. As shown in FIG. 3 (a), one peripheral edge 21b from the center ellipse to the notch opening 20 is formed in a straight line 21c so that the suspension bolt 41 is smoothly guided into the insertion space 21 with importance. Yes. However, the peripheral edge 21b of the insertion space 21 of the upper clamping piece 16 may also be formed in the same shape as the locking portion 19 of the lower clamping piece 17.

ここで、下側挟持片１７の挿入空間２１の周縁２１ｂは、中央部の円から切欠開口２０に至る一方が傾斜線２１ｄに形成されているが、例えば、図８に示すように、中央部の円から切欠開口２０に至る一方を円弧２１ｅに形成してもよく、この場合も同様に、吊りボルト４１に対する下側挟持片１７の係止部１９の係止を解除され難くすることができる。   Here, the peripheral edge 21b of the insertion space 21 of the lower holding piece 17 is formed with an inclined line 21d from the circle at the center to the cutout opening 20. For example, as shown in FIG. One from the circle to the cutout opening 20 may be formed in an arc 21e. In this case as well, the locking of the locking portion 19 of the lower holding piece 17 with respect to the suspension bolt 41 can be made difficult to be released. .

なお、上記実施形態の取着部１１は、図１及び図２では、左側の側壁１３の上側挟持片１６及び右側の側壁１４の上側挟持片１６は、取着部１１の上部側において吊りボルト４１を両側方から弾性的に挟持し、下部側の下側挟持片１７の係止部１９は、振れ止め部２３となっているが、上下逆にして、側壁１３の下側挟持片１７及び側壁１４の下側挟持片１７が、取着部１１の下部側において吊りボルトを両側方から弾性的に挟持し、上部側の上側挟持片１６の係止部１９が、振れ止め部２３となるものとしてもよい。   In FIG. 1 and FIG. 2, the attachment portion 11 of the above embodiment is configured such that the upper holding piece 16 of the left side wall 13 and the upper holding piece 16 of the right side wall 14 are suspended bolts on the upper side of the attachment portion 11. 41 is elastically clamped from both sides, and the locking portion 19 of the lower clamping piece 17 on the lower side is a steady-rest portion 23. However, the lower clamping piece 17 of the side wall 13 and The lower holding piece 17 of the side wall 14 elastically holds the suspension bolt from both sides on the lower side of the attachment portion 11, and the locking portion 19 of the upper holding pin 16 on the upper side becomes the steady portion 23. It may be a thing.

ところで、上記実施形態では、前述のように、ケーブル４２を支持する支持部３１は、図４(a)の平面図に示すように、取着部１１の左右両側壁において、挟持された吊りボルト４１の軸心Ｏを通る側方であって、白抜き矢印で示す吊りボルト４１の相対的な挿入方向とは直交する側方に一対取付けられている。図４(b)の右側面図で示せば、支持部３１は、上下方向の交線Ｌ上に取付けられている。支持部３１をこの位置に取付けたのは、前述のように、ケーブル４２の荷重によって、図４(b)に示す、吊りボルト４１との当接部Ｔを軸に取着体１を回動させようとするモーメントが発生しないようにするためであり、それにより、支持部３１で支持されるケーブル４２の荷重が大きい場合でも、取着体１が吊りボルト４１から抜脱するのをより確実に防止するためである。   By the way, in the said embodiment, as above-mentioned, as shown in the top view of Fig.4 (a), the support part 31 which supports the cable 42 is the suspension bolt clamped in the right-and-left both sides wall of the attachment part 11. FIG. A pair is attached to the side passing through the axis O of 41 and to the side orthogonal to the relative insertion direction of the suspension bolt 41 indicated by the white arrow. If it shows in the right view of FIG.4 (b), the support part 31 is attached on the intersection line L of an up-down direction. As described above, the support portion 31 is attached to this position by rotating the attachment 1 around the contact portion T with the suspension bolt 41 shown in FIG. This is to prevent the moment to be generated from occurring, so that even when the load of the cable 42 supported by the support portion 31 is large, the attachment body 1 can be more reliably removed from the suspension bolt 41. This is to prevent it.

しかし、本発明を実施する場合には、支持部３１は、必ずしも厳密に図４(b)の交線Ｌ上に設置したものにしなくてもよく、交線Ｌから僅かに取着部１１の挿入開口側１２に離間した位置に設けることもできる。具体的には、支持部３１を取着するためのリベット３２は、図９に示すように、吊りボルト４１の軸心を通る側方であって吊りボルト４１の挿入方向と直交する側方である箇所つまり交線Ｌから挿入開口側１２に所定距離離間した位置に取付けてもよい。この場合の離間距離Ｑは約２ｍｍに設定するのが望ましい。   However, when the present invention is carried out, the support portion 31 does not necessarily have to be installed strictly on the intersection line L in FIG. 4B, and the attachment portion 11 slightly extends from the intersection line L. It can also be provided at a position separated from the insertion opening side 12. Specifically, as shown in FIG. 9, the rivet 32 for attaching the support portion 31 is a side passing through the axis of the suspension bolt 41 and a side perpendicular to the insertion direction of the suspension bolt 41. You may attach to the position spaced apart from the certain location, ie, the intersection line L, to the insertion opening side 12 by predetermined distance. In this case, the separation distance Q is preferably set to about 2 mm.

支持部３１を取着部１１の側壁１３、１４において交線Ｌから挿入開口側１２に離間した位置に取付ける理由は次の通りである。即ち、前述したように、支持部３１は、リベット３２の取付部分から垂直下方に延出してケーブル４２の載置部３３が形成され、図２に示すように、吊りボルト４１側の湾曲部は吊りボルト４１に当接する状態に取付けられるのが望ましい。これにより、一つには、ケーブル４２の荷重を吊りボルト４１によって支持させ、支持部３１の回動を抑えて一対の下側挟持片１７，１７の挿入空間２１の重なり部分２１ａが拡張するのを防ぐことができるからである。しかし、支持部３１を取着部１１の側壁１３、１４において交線Ｌ上に取付ければ、リベット３２の取付部分から垂直下方に延出している支持部３１の湾曲部を吊りボルト４１の外面に当接させることはできるものの、その一方で、次の事態が生ずることもある。即ち、丸棒等で形成された支持部３１の湾曲部は吊りボルト４１とはその外面の円弧の頂点において点接触または線接触のやや不安定な状態で当接するから、図１０(a)の説明図に示すように、支持部３１の湾曲部のぶれやケーブル４２の載置状態などによって支持部３１の湾曲部が吊りボルト４１の外面の頂点からいずれかの側の外面に沿って滑って移動することがある。   The reason why the support portion 31 is attached to the side wall 13, 14 of the attachment portion 11 at a position spaced from the intersection line L to the insertion opening side 12 is as follows. That is, as described above, the support portion 31 extends vertically downward from the attachment portion of the rivet 32 to form the placement portion 33 of the cable 42. As shown in FIG. It is desirable to attach to the state where it abuts on the suspension bolt 41. Thereby, for example, the load of the cable 42 is supported by the suspension bolt 41, and the overlapping portion 21 a of the insertion space 21 of the pair of lower holding pieces 17 and 17 is expanded while suppressing the rotation of the support portion 31. It is because it can prevent. However, if the support portion 31 is attached on the intersection line L on the side walls 13 and 14 of the attachment portion 11, the curved portion of the support portion 31 extending vertically downward from the attachment portion of the rivet 32 is used as the outer surface of the suspension bolt 41. However, on the other hand, the following situation may occur. That is, the curved portion of the support portion 31 formed of a round bar or the like abuts the suspension bolt 41 at the apex of the arc of the outer surface in a slightly unstable state of point contact or line contact. As shown in the explanatory diagram, the curved portion of the support portion 31 slips along the outer surface on either side from the apex of the outer surface of the suspension bolt 41 due to the fluctuation of the curved portion of the support portion 31 or the mounting state of the cable 42. May move.

その場合、支持部３１の湾曲部がケーブル４２の荷重によって、図１０(b)に示すように、吊りボルト４１の外面に沿って取着部１１の挿入開口側１２に滑って移動すれば、ケーブル４２の荷重による力は吊りボルト４１を取着部１１の奥側即ち連結板部１５側に押出すことになり、抜脱とは逆方向に作用するので、取着体１が吊りボルト４１から抜脱するのは防止され、格別不具合は生じない。しかし、支持部３１の湾曲部が、ケーブル４２の荷重によって、逆に、図１０(c)に示すように、吊りボルト４１の外面に沿って取着部１１の奥側即ち連結板部１５側に滑って移動すれば、ケーブル４２の荷重による押圧力は吊りボルト４１を取着部１１の挿入開口側１２に押出すことになり、抜脱方向に作用するので、取着体１は吊りボルト４１から抜脱する虞が出てくる。そこで、支持部３１が取着部１１の側壁１３、１４において交線Ｌ上に設けられている場合には、支持部３１の湾曲部はいずれかの側に滑り易い不安定状態にあるところ、予め、支持部３１を取着部１１の側壁１３、１４において交線Ｌから挿入開口側１２に離間した位置に取付け、支持部３１の湾曲部が取着部１１の挿入開口側１２において吊りボルト４１に当接するようにし、もって、吊りボルト４１の外面において取着部１１の奥側に滑って移動するのを確実に防止するようにして、取着体１が吊りボルト４１から抜脱するのを確実に防止するようにしたのである。   In that case, if the curved part of the support part 31 slides and moves to the insertion opening side 12 of the attachment part 11 along the outer surface of the suspension bolt 41 as shown in FIG. The force due to the load of the cable 42 pushes the suspension bolt 41 to the back side of the attachment portion 11, that is, the connecting plate portion 15 side, and acts in the direction opposite to the removal, so that the attachment body 1 is attached to the suspension bolt 41. It is prevented from being pulled out of the box, and no special malfunction occurs. However, the curved portion of the support portion 31 is reversed by the load of the cable 42, as shown in FIG. 10 (c). If it slides and moves, the pressing force due to the load of the cable 42 pushes the suspension bolt 41 to the insertion opening side 12 of the attachment portion 11 and acts in the removal direction. There is a risk that it will be removed from 41. Therefore, when the support portion 31 is provided on the intersection line L in the side walls 13 and 14 of the attachment portion 11, the curved portion of the support portion 31 is in an unstable state that is slidable on either side. The support portion 31 is previously attached to the side wall 13, 14 of the attachment portion 11 at a position spaced from the intersection line L to the insertion opening side 12, and the curved portion of the support portion 31 is suspended from the insertion opening side 12 of the attachment portion 11. 41, so that the attachment body 1 is removed from the suspension bolt 41 so as to surely prevent the outer surface of the suspension bolt 41 from slipping and moving to the back side of the attachment portion 11. This is surely prevented.

なお、このように、支持部３１を取着部１１の側壁１３、１４において交線Ｌから挿入開口側１２に離間した位置に取付けた場合には、ケーブル４２の荷重が加わることによって、取着体１を図４(b)とは反対の反時計方向に回動させようとするモーメントが発生するものの、取着体１は上側挟持片１６の係止部１９が吊りボルト４１の外面に圧接する方向に回動する、即ち抜脱とは逆方向に回動することになるので、吊りボルト４１から抜脱することはない。   In this way, when the support portion 31 is attached to the side wall 13 or 14 of the attachment portion 11 at a position separated from the intersection line L to the insertion opening side 12, the attachment of the attachment portion due to the load of the cable 42 is applied. Although a moment is generated to rotate the body 1 in the counterclockwise direction opposite to that in FIG. 4B, the attachment body 1 has the locking portion 19 of the upper clamping piece 16 pressed against the outer surface of the suspension bolt 41. Since it rotates in the direction opposite to that of the removal, that is, in the direction opposite to the removal, the suspension bolt 41 will not be removed.

次に、吊りボルト４１の側方である箇所即ち交線Ｌからの離間距離Ｑが約２ｍｍの大きさであるのが望ましいのは、離間距離Ｑが２ｍｍより小さ過ぎると、支持部３１の湾曲部が吊りボルト４１の外面に沿って取着部１１の奥側に滑り込むのを確実に防止できるとは限らないからである。また、その一方、離間距離Ｑが２ｍｍより大き過ぎると、外径が通常Ｗ３／８即ちいわゆる３分またはＷ１／２即ちいわゆる４分である吊りボルト４１の外面に支持部３１の湾曲部が当接しなくなるため、前述した吊りボルト４１との当接による効果が得られなくなるからである。即ち、支持部３１がケーブル４２の荷重によって傾いたり、その荷重によって円弧が伸ばされて上部開口が広がるのを吊りボルト４１で支持して防止できるなどの効果が得られなくなるからである。但し、離間距離Ｑは必ずしも約２ｍｍの大きさに限られるものではない。   Next, it is desirable that the distance Q from the part that is the side of the suspension bolt 41, that is, the intersection line L, is about 2 mm. If the distance Q is too small, the curvature of the support portion 31 is increased. This is because it is not always possible to reliably prevent the portion from sliding along the outer surface of the suspension bolt 41 into the back side of the attachment portion 11. On the other hand, if the separation distance Q is too larger than 2 mm, the curved portion of the support portion 31 is not applied to the outer surface of the suspension bolt 41 whose outer diameter is usually W3 / 8, that is, so-called 3 minutes or W1 / 2, that is, so-called 4 minutes. This is because the contact with the suspension bolt 41 described above cannot be obtained because the contact does not occur. In other words, it is impossible to obtain an effect that the support portion 31 can be supported by the suspension bolt 41 to prevent the support portion 31 from being inclined by the load of the cable 42 or the arc from being extended by the load and the upper opening being widened. However, the separation distance Q is not necessarily limited to a size of about 2 mm.

なお、上記実施形態では、取着部１１の側壁における支持部３１の取付部分であるリベット３２の取付部分は、交線Ｌから挿入開口側１２に離間した位置に取付けたものとしているが、図１１の右側面図に示すように、リベット３２の取付部分は交線Ｌ上にあるものの、支持部３１の湾曲部分はリベット３２の取付部分から僅かに傾斜して垂下し、湾曲部における吊りボルト４１との当接部分即ち図１１において×印で示す部分が交線Ｌから所定距離離間しているものとしてもよく、この場合も同様の効果を得ることができる。   In the above embodiment, the attachment portion of the rivet 32 which is the attachment portion of the support portion 31 on the side wall of the attachment portion 11 is attached at a position spaced from the intersection line L to the insertion opening side 12. 11, the attachment portion of the rivet 32 is on the intersection line L, but the curved portion of the support portion 31 hangs slightly from the attachment portion of the rivet 32, and the suspension bolt in the curved portion The contact portion with 41, that is, the portion indicated by x in FIG. 11 may be separated from the intersection line L by a predetermined distance. In this case, the same effect can be obtained.

ところで、互いに対向する一対の挿入空間２１は、図５(a)に示すように、一部が吊りボルト４１の軸方向から見て互いに重なり合うよう形成され、かつ、この重なり部分２１ａは切欠開口２０を介して外部に連通するよう形成されているが、必ずしもこれに限られる必要はない。図１２(a)の取着体１は、一対の上側挟持片１６，１６等の挿入空間２１，２１は、一部が吊りボルト４１の軸方向から見て互いに重なり合うよう形成されているが、この重なり部分２１ａは切欠開口２０を介して外部に連通してはいない。しかし、この取着体１においても、一対の上側挟持片１６，１６等における吊りボルト４１の挿入側の端縁部２２を、図１２(a)に示すような傾斜線に形成して、押し込み時に吊りボルト４１が左右一対の端縁部２２，２２の交差部分に導かれるように形成すれば、取着体１は、同様に、吊りボルト４１に対して押し込むだけで、一対の上側挟持片１６，１６等は弾性復帰力に抗して互いに閉じられる方向に移動し、重なり部分２１ａは左右に拡張して外部と連通するようになる。そこで、吊りボルト４１に対して更に押し込めば、吊りボルト４１を一対の挿入空間２１，２１の重なり部分２１ａの内部に導いて係止させることができ、一対の上側挟持片１６，１６等により弾性的に吊りボルト４１を挟持させて取着体１を取着することができる。   Incidentally, as shown in FIG. 5A, the pair of insertion spaces 21 facing each other are formed so as to partially overlap each other when viewed from the axial direction of the suspension bolt 41, and the overlapping portion 21 a is formed in the notch opening 20. However, the present invention is not necessarily limited to this. In the attachment body 1 in FIG. 12A, the insertion spaces 21 and 21 such as the pair of upper clamping pieces 16 and 16 are partially overlapped when viewed from the axial direction of the suspension bolt 41. The overlapping portion 21 a does not communicate with the outside through the notch opening 20. However, also in this attachment body 1, the end edge 22 on the insertion side of the suspension bolt 41 in the pair of upper clamping pieces 16, 16 is formed in an inclined line as shown in FIG. If the suspension bolt 41 is sometimes formed so as to be guided to the intersection of the pair of left and right end edges 22, 22, the attachment body 1 is similarly simply pushed into the suspension bolt 41 to form a pair of upper clamping pieces. 16, 16 and the like move in a direction to be closed against each other against the elastic restoring force, and the overlapping portion 21a extends left and right to communicate with the outside. Therefore, if the suspension bolt 41 is further pushed into the suspension bolt 41, the suspension bolt 41 can be guided and locked inside the overlapping portion 21a of the pair of insertion spaces 21, 21, and is elasticized by the pair of upper clamping pieces 16, 16 and the like. Thus, the attachment body 1 can be attached by sandwiching the suspension bolt 41.

更には、対向する一対の挿入空間２１，２１は、取着前の状態においては、必ずしも、一部が吊りボルト４１の軸方向から見て互いに重なり合うように形成されていなくてもよい。図１２(b)の取着体１は、対向する一対の挿入空間２１，２１の一部が互いに重なり合うようには形成されていない。但し、図１２(a)の取着体１のように、一対の上側挟持片１６，１６等の挿入側の端縁部２２は、図１２(a)に示すような傾斜線に形成され、押し込み時に吊りボルト４１が左右一対の端縁部２２の交差部分に導かれるように形成されている。したがって、この取着体１の場合も、吊りボルト４１に対して強制的に押し込むことにより、一対の上側挟持片１６，１６等を弾性復帰力に抗して互いに閉じられる方向に移動させて、取着時に、一対の係止部１９，１９に外部と連通する重なり部分２１ａを形成することが可能である。そこで、同様にして、吊りボルト４１に押し込むことにより、吊りボルト４１を対向する一対の挿入空間２１，２１の双方の内部に導いて係止させて取着体１を取着することができる。   Furthermore, the pair of opposed insertion spaces 21 and 21 do not necessarily have to be partially formed so as to overlap each other when viewed from the axial direction of the suspension bolt 41 in a state before attachment. The attachment body 1 in FIG. 12B is not formed so that a part of the pair of insertion spaces 21 and 21 facing each other overlap each other. However, like the attachment body 1 in FIG. 12 (a), the insertion-side end edges 22 of the pair of upper clamping pieces 16, 16 and the like are formed in an inclined line as shown in FIG. 12 (a). The suspension bolt 41 is formed so as to be guided to the intersection of the pair of left and right end edges 22 when pushed. Therefore, also in the case of this attachment body 1, by forcibly pushing into the suspension bolt 41, the pair of upper clamping pieces 16, 16 and the like are moved in a direction to be closed against each other against the elastic restoring force, At the time of attachment, it is possible to form an overlapping portion 21 a communicating with the outside in the pair of locking portions 19, 19. Therefore, by similarly pushing the suspension bolt 41 into the suspension bolt 41, the attachment body 1 can be attached by guiding the suspension bolt 41 to both the opposing insertion spaces 21 and 21 and locking them.

また、上記実施形態においては、切欠係止部１９は、取着部１１全体において、左右一対で上下二組の計４箇所に設けられているが、必ずしもこれに限られるものではない。例えば、図１３に示す取着体１は、左側の側壁１３においては、下側挟持片１７は形成されておらず、係止部１９は上側挟持片１６のみに設けられている。即ち、取着部１１全体として係止部１９は計３個設けられており、吊りボルト４１には、上から、左側、右側、左側の順に、図１３の黒丸で示す３箇所で当接し、挟持するようになっている。この取着体１の場合も、３個の係止部１９は、吊りボルト４１の軸方向の異なる位置に設けられているとともに、交互に異なる側から吊りボルト４１に係止するので、吊りボルト４１に対して傾斜することなく一定の垂直姿勢に安定して保持取着される。ここで、３個の係止部１９のうち、右側の側壁１４の下側挟持片１７の係止部１９は振れ止め部２３となる。なお、この３個の係止部１９を有する取着体１においても、上下逆にして、左右一対の挟持片を下部側に設け、振れ止め部２３を上部側に設けてもよい。   Moreover, in the said embodiment, although the notch latching | locking part 19 is provided in a total of four places of two sets of upper and lower two pairs in the attachment part 11 whole, it is not necessarily restricted to this. For example, in the attachment body 1 shown in FIG. 13, the lower holding piece 17 is not formed on the left side wall 13, and the locking portion 19 is provided only on the upper holding piece 16. That is, a total of three locking portions 19 are provided as the attachment portion 11 as a whole, and the suspension bolt 41 comes into contact with the suspension bolt 41 from the top, the left side, the right side, and the left side in three places indicated by black circles in FIG. It is designed to be pinched. Also in the case of this attachment 1, since the three locking portions 19 are provided at different positions in the axial direction of the suspension bolt 41 and are alternately latched to the suspension bolt 41 from different sides, the suspension bolt It is stably held and attached in a constant vertical posture without being inclined with respect to 41. Here, of the three locking portions 19, the locking portion 19 of the lower holding piece 17 of the right side wall 14 serves as a steady rest portion 23. Even in the attachment body 1 having the three locking portions 19, the pair of left and right clamping pieces may be provided on the lower side and the steadying portion 23 may be provided on the upper side.

次に、本発明の別の取着体を図１４に示す。
図１４(a)、(b)に示す取着体１Ａは、図１等に示す前述の取着体１と比較して、下部側の一対の下側挟持片１７，１７がなく、振れ止め部２３としての下側挟持片１７の係止部１９は設けられていないが、それに替えて、振れ止め部２３が背面側の連結板部１５に突設された振れ止め片２４の切欠係止孔２５で形成されている。振れ止め片２４は、連結板部１５に直交してその下端から紙面の手前側に向けて屈曲し突出する屈曲板により一体に形成されている。ここで、上部側の一対の上側挟持片１６，１６における切欠孔１８の切欠開口２０の開口幅が狭まっていることによって紙面の手前側への振れは防止できるので、振れ止め片２４の切欠係止孔２５は、図１４の左右方向への振れを防止すればよい。そこで、切欠係止孔２５は、吊りボルト４１の外面に対応して略半円形状に切欠形成されたものとなっている。なお、切欠係止孔２５の切欠開口２６の開口幅を僅かに小さく形成して切欠開口２６からの抜脱をより確実に防止するようにしてもよい。また、切欠係止孔２５は、吊りボルト４１と当接することにより取着部１１の振れを防止できるものであれば、その形状は問わず、角形状等に形成してもよい。 Next, another attachment body of the present invention is shown in FIG.
The attachment body 1A shown in FIGS. 14 (a) and 14 (b) does not have a pair of lower holding pieces 17 and 17 on the lower side as compared with the attachment body 1 shown in FIG. The locking part 19 of the lower holding piece 17 as the part 23 is not provided, but instead, the notch locking of the steadying piece 24 in which the steadying part 23 projects from the connecting plate part 15 on the back side is provided. The hole 25 is formed. The steady rest piece 24 is integrally formed by a bent plate that is perpendicular to the connecting plate portion 15 and bends and protrudes from the lower end toward the front side of the drawing. Here, since the opening width of the notch opening 20 of the notch hole 18 in the pair of upper holding pieces 16 and 16 on the upper side is narrowed, it is possible to prevent the paper surface from swinging toward the front side. The stop hole 25 should just prevent the shake | fluctuation to the left-right direction of FIG. Therefore, the notch locking hole 25 is formed in a substantially semicircular shape corresponding to the outer surface of the suspension bolt 41. It should be noted that the opening width of the notch opening 26 of the notch locking hole 25 may be formed to be slightly smaller so as to prevent the removal from the notch opening 26 more reliably. Further, the cutout locking hole 25 may be formed in a square shape or the like as long as it can prevent the attachment portion 11 from swinging by contacting the suspension bolt 41.

ここで、一対の上側挟持片１６，１６の係止部１９，１９及び振れ止め部２３の振れ止め片２４の切欠係止孔２５が吊りボルト４１の軸方向の異なる３箇所において交互に異なる側から吊りボルト４１の外面に当接し係止すれば、取着体１Ａは、吊りボルト４１に対して振れることなく一定の垂直姿勢に安定して保持され取着される。したがって、取着体１Ａは、例えば、図１４(c)に示すように、振れ止め片２４を吊りボルト４１の片側のみに形成し、片側のみが当接して振れ止めるものとしてもよい。
なお、図１４においては、係止部１９及び切欠係止孔２５は、図１４(a)の黒丸で示すように、上から、左側、右側、左側の順で吊りボルト４１に当接している。
また、この取着体の場合も、上下逆にして、左右一対の挟持片を下部側に設け、振れ止め部２３としての振れ止め片２４の切欠係止孔２５を上部側に設けてもよい。 Here, the locking portions 19, 19 of the pair of upper clamping pieces 16, 16 and the notch locking holes 25 of the steadying piece 24 of the steadying portion 23 are alternately different at three different locations in the axial direction of the suspension bolt 41. 1A, the attachment body 1A is stably held and attached in a fixed vertical posture without shaking with respect to the suspension bolt 41. Therefore, for example, as shown in FIG. 14 (c), the attachment body 1 </ b> A may be configured such that the steadying piece 24 is formed only on one side of the suspension bolt 41, and only one side is in contact with the steadying piece.
In FIG. 14, the locking portion 19 and the notch locking hole 25 are in contact with the suspension bolt 41 in order from the top, the left side, the right side, and the left side, as indicated by the black circles in FIG. 14 (a). .
Also in the case of this attachment, the pair of left and right clamping pieces may be provided on the lower side upside down, and the notch locking hole 25 of the steadying piece 24 as the steadying part 23 may be provided on the upper side. .

そして、上記実施形態の支持部３１は、上部が開口する略円弧状に形成されているが、その形状に限られず、細径のケーブル４２を支持する場合は、縦長の略Ｕ字状に形成したり横長の棒状に形成するなどして複数のケーブル４２を支持するものとしてもよい。 By the way, in the said embodiment, although the support part 31 is attached to the side wall of the both sides of the attachment part 11, you may attach to either one or the connection board part 15 of the back side of the attachment part 11 You may attach to.
And although the support part 31 of the said embodiment is formed in the substantially circular arc shape which an upper part opens, it is not restricted to the shape, When supporting the small diameter cable 42, it is formed in the vertically long substantially U shape. It is good also as what supports the some cable 42 by forming in the shape of a horizontally long stick.

加えて、上記実施形態の取着部１１は、各係止部１９が、吊りボルト４１に対して、上から、左側、右側、右側、左側の順に当接しているが、側壁１３の上側挟持片１６、側壁１４の上側挟持片１６、側壁１３の下側挟持片１７及び側壁１４の下側挟持片１７が高さ方向において互い違いに配設され、各係止部１９が、吊りボルト４１に対して、例えば、上から、左側、右側、左側、右側の順に当接するものとしてもよい。   In addition, in the attachment portion 11 of the above-described embodiment, each locking portion 19 is in contact with the suspension bolt 41 from the top to the left, right, right, and left in this order. The pieces 16, the upper holding pieces 16 of the side walls 14, the lower holding pieces 17 of the side walls 13, and the lower holding pieces 17 of the side walls 14 are alternately arranged in the height direction, and each locking portion 19 is attached to the suspension bolt 41. On the other hand, it is good also as what contact | abuts in order of the left side, the right side, the left side, and the right side from the top, for example.

また、上記実施形態の取着部１１は、吊りボルト４１を両側方から弾性的に挟持する一対の挟持片を吊りボルト４１の軸方向に二組備え、うち一組を振れ止め部２３としているが、一対の挟持片を吊りボルト４１の軸方向に三組以上備え、うち二組以上を振れ止め部２３としたものに形成してもよい。   Moreover, the attachment part 11 of the said embodiment is provided with two sets of a pair of clamping pieces which clamp the suspension bolt 41 elastically from both sides in the axial direction of the suspension bolt 41, and one set is used as the steady rest part 23. However, three or more pairs of sandwiching pieces may be provided in the axial direction of the suspension bolt 41, and two or more sets of them may be formed as the steady rests 23.

また、上記実施形態の取着体１は、ケーブル４２を支持する場合に適用しているが、本発明を実施する場合には、これに限られるものではなく、他の配線材や給水管、給湯管等の配管材にも適用することができる。   Moreover, although the attachment body 1 of the said embodiment is applied when supporting the cable 42, when implementing this invention, it is not restricted to this, Other wiring materials, a water supply pipe, It can also be applied to piping materials such as hot water pipes.

更には、上記実施形態の取着体１は、取着部１１を基体としてこれにケーブル４２等の配設体を支持する支持部３１を設けた形態のものであるが、取着体１は、吊りボルト４１に取着される配線ボックスや火災報知器等の器具、機器類などを基体としてこれに取着部１１を取付けた形態のもの、即ち、配線ボックス等の一部に取着部１１を備えた形態のものであってもよい。この取着部１１を備えた配線ボックス等も吊りボルト４１に取着されるものであり、取着体１を構成するものとなる。   Furthermore, the attachment body 1 of the above-described embodiment is a form in which the attachment portion 11 is used as a base and a support portion 31 for supporting an arrangement body such as a cable 42 is provided on the attachment portion 11.

〈ナット体〉
次に、本発明の実施形態のナット体を図１６に基づいて説明する。
図１６に示すナット体２は、前述の取着体１の取着部１１に相当する単体で構成され、この取着部１１と同様の構成となっている。即ち、ナット体２は、左右両側に配設された一対の側壁１３，１４と、吊りボルト４１の挟持状態における振れを防止する振れ止め部２３とを備えている。更に、一対の側壁１３，１４のそれぞれの上端部及び下端部からは水平方向に挟持片が設けられており、各挟持片には、反対側から吊りボルト４１に当接して係止する係止部１９が設けられている。ナット体２は鋼板等で形成されており、係止部１９の縁部は吊りボルト４１の螺子溝内に嵌入して係止するようになっている。そして、ナット体２は吊りボルト４１に対して回転させることにより吊りボルト４１の軸方向に移動させることができるようになっている。即ち、ナット体２は一対の係止部１９，１９が吊りボルト４１を側方から挟持するとともに、通常のナットとしての締付機能をも有している。 <Nut body>
Next, a nut body according to an embodiment of the present invention will be described with reference to FIG.
A nut body 2 shown in FIG. 16 is configured as a single unit corresponding to the mounting portion 11 of the mounting body 1 described above, and has the same configuration as the mounting portion 11. That is, the nut body 2 includes a pair of side walls 13 and 14 disposed on both the left and right sides, and a steady stop portion 23 that prevents the suspension bolt 41 from swinging in a sandwiched state. Further, a holding piece is provided in the horizontal direction from the upper end and the lower end of each of the pair of side walls 13 and 14, and each holding piece is brought into contact with and suspended from the suspension bolt 41 from the opposite side. A part 19 is provided. The nut body 2 is formed of a steel plate or the like, and the edge portion of the locking portion 19 is fitted into the screw groove of the suspension bolt 41 and locked. The nut body 2 can be moved in the axial direction of the suspension bolt 41 by rotating with respect to the suspension bolt 41. That is, the nut body 2 has a pair of locking portions 19, 19 holding the suspension bolt 41 from the side and also has a tightening function as a normal nut.

このナット体２を使用して、例えば、ケーブル４２を支持するケーブルラック４８を天井等に設置するには、図１６に示すように、天井から垂設された一対の吊りボルト４１，４１の間に断面略Ｌ字形状の鋼材４７を水平状態に配置し、鋼材４７の両端部に設けた貫通孔または切欠孔に吊りボルト４１を挿通する。続いて、取着体１と同じ要領で、上下一対のナット体２，２を鋼材４７の上方及び下方において吊りボルト４１に側方から押し込んで取着する。この状態においては、少なくとも一対の係止部１９，１９は吊りボルトを側方から挟持するとともに、振れ止め部２３がナット体２の振れ、傾きを防止する。次いで、各ナット体２を通常のナットの螺着と同じ要領で、スパナやプライヤ等の工具を使用して或いは手で把持して回転し、吊りボルト４１に沿って下方または上方に移動させて鋼材４７に当接させ、締付けることにより、２個のナット体２で鋼材４７を上下両方向から挟み付ける。これにより、鋼材４７の端部は吊りボルト４１に取着固定される。これを両吊りボルト４１について行なえば、鋼材４７は、図１６に示すように、両吊りボルト４１間に水平状態に架設される。そこで、この鋼材４７の上にケーブルラック４８を載置すればよい。その後は、このケーブルラック４８上にケーブル４２を載置し、布設路に沿って布設する。   For example, in order to install the cable rack 48 supporting the cable 42 on the ceiling or the like using the nut body 2, as shown in FIG. 16, between the pair of suspension bolts 41, 41 suspended from the ceiling. A steel material 47 having a substantially L-shaped cross section is horizontally arranged, and the suspension bolt 41 is inserted into a through hole or a notch hole provided at both ends of the steel material 47. Subsequently, in the same manner as the attachment body 1, the pair of upper and lower nut bodies 2, 2 are pushed into the suspension bolt 41 from the side above and below the steel material 47 and attached. In this state, at least the pair of locking portions 19, 19 hold the suspension bolt from the side, and the steadying portion 23 prevents the nut body 2 from swinging and tilting. Next, each nut body 2 is rotated by using a tool such as a wrench or a plier or by gripping it by hand in the same manner as screwing a normal nut, and is moved downward or upward along the suspension bolt 41. By abutting and tightening on the steel material 47, the steel material 47 is sandwiched from both the upper and lower directions by the two nut bodies 2. Thereby, the edge part of the steel material 47 is attached and fixed to the suspension bolt 41. If this is performed for both suspension bolts 41, the steel material 47 is laid horizontally between the suspension bolts 41 as shown in FIG. Therefore, the cable rack 48 may be placed on the steel material 47. Thereafter, the cable 42 is placed on the cable rack 48 and installed along the installation path.

このナット体２によれば、側方から吊りボルト４１に取着することができるので、単にナット体２を吊りボルト４１に側方から押し込んで取着し、僅かに回すだけで、鋼材４７を上下方向から挟み込んで吊りボルト４１の所望する任意位置に簡単に取着し固定することができる。また、側方から取着できることにより、吊りボルト４１に他の部材や取着体等が既に取着されている場合においても、これらの部材や取着体等を取り外すことなくこれらの中間位置などにナット体２を自在に取着し、回転して締付けて鋼材４７等を増設することができる。   According to this nut body 2, since it can be attached to the suspension bolt 41 from the side, the steel body 47 can be attached by simply pushing the nut body 2 into the suspension bolt 41 from the side and attaching it. It can be easily attached and fixed at any desired position of the suspension bolt 41 by being sandwiched from above and below. Further, by being able to attach from the side, even when other members, attachments, etc. are already attached to the suspension bolt 41, these intermediate positions, etc. can be obtained without removing these members, attachments, etc. The nut body 2 can be freely attached to and rotated to tighten the steel member 47 and the like.

ところで、ナット体２を吊りボルト４１に側方から取着した後に、工具などを使用してナット体２を回転させて締付ける際には、ナット体２の側壁１３及び側壁１４を両側から挟み付けながら回すから、その挟み付けによってナット体２の回転操作中に両側壁が押圧されて互いに近接し、係止部１９が逆に互いに離間して、吊りボルト４１の係止ががたついたり、吊りボルト４１が切欠開口２０から抜け外れてしまう虞があったりして、円滑にナット体２の締付作業を行なえないことがある。そこで、ナット体２を吊りボルト４１に側方から取着した後であってナット体２を回転する直前に、工具等による両側からの押圧によって側壁１３と側壁１４とが互いに近接し、一対の係止部１９，１９が互いに離間するのを防止する措置を講じておくのが望ましい。   By the way, when the nut body 2 is attached to the suspension bolt 41 from the side and then tightened by rotating the nut body 2 using a tool or the like, the side wall 13 and the side wall 14 of the nut body 2 are sandwiched from both sides. Since the nut body 2 is rotated while being turned, both side walls are pressed and come close to each other during the rotation operation of the nut body 2, the locking portions 19 are separated from each other, and the suspension bolt 41 is locked. There is a possibility that the suspension bolt 41 may come off from the notch opening 20, and the nut body 2 may not be tightened smoothly. Therefore, after the nut body 2 is attached to the suspension bolt 41 from the side and immediately before the nut body 2 is rotated, the side wall 13 and the side wall 14 come close to each other by pressing from both sides with a tool or the like, and a pair of It is desirable to take measures to prevent the locking portions 19 from being separated from each other.

具体的には、例えば、図１７に示すように、側壁１４の上側挟持片１６に螺子孔１６ａを設け、ナット体２を回転する直前に、前記螺子孔１６ａにビス４９を螺着してその螺子溝と側壁１３の上側挟持片１６の先端とを螺合状態に係合させることが考えられる。これによれば、側壁１３の上側挟持片１６の先端がビス４９の螺子部外面に当接して移動が規制され、側壁１３と側壁１４とが互いに近接するのが防止され、一対の係止部１９，１９が互いに離間するのが防止される。また、図示しないが、ナット体２を回転する直前に、両側壁間につっかい棒やつっかい板を水平状態に介挿して側壁１３と側壁１４とが互いに近接するのを防止するようにしてもよい。或いは、側壁１４の上側挟持片１６の切欠孔１８において、吊りボルト４１の貫通後に形成される隙間、即ち図１７に示す隙間Ｓ内に吊りボルト４１が水平方向に移動するのを規制する詰め部材を挿着して、両側壁が互いに近接するのを防止するようにしてもよい。その他、両側壁同士が近接するのを防止する各種手段を採り得る。   Specifically, for example, as shown in FIG. 17, a screw hole 16a is provided in the upper clamping piece 16 of the side wall 14, and a screw 49 is screwed into the screw hole 16a immediately before the nut body 2 is rotated. It is conceivable to engage the screw groove and the tip of the upper clamping piece 16 of the side wall 13 in a screwed state. According to this, the tip of the upper clamping piece 16 of the side wall 13 abuts against the outer surface of the screw part of the screw 49, the movement is restricted, the side wall 13 and the side wall 14 are prevented from approaching each other, and a pair of locking parts 19 and 19 are prevented from being separated from each other. Although not shown, immediately before the nut body 2 is rotated, a side bar 13 and side wall 14 are prevented from approaching each other by inserting a horizontal bar or a horizontal plate between both side walls in a horizontal state. Also good. Alternatively, in the cutout hole 18 of the upper clamping piece 16 of the side wall 14, a packing member that restricts the suspension bolt 41 from moving in the gap formed after the suspension bolt 41 passes, that is, the gap S shown in FIG. May be inserted to prevent the side walls from approaching each other. In addition, various means for preventing the side walls from approaching each other can be adopted.

なお、吊りボルト４１にナット体２を取着したときに、前述の両側壁が互いに近接するのを防止する措置を講じておけば、上下一対のナット体２，２を回転し締付けて吊りボルト４１に鋼材４７を固定した後に、何らかの拍子に両側壁が挟圧されて係止部１９相互が離間し締付強度が低下してしまうのを確実に防止することもできる。   In addition, when the nut body 2 is attached to the suspension bolt 41, if measures are taken to prevent the above-mentioned side walls from coming close to each other, the pair of upper and lower nut bodies 2, 2 are rotated and tightened to form the suspension bolt. After fixing the steel material 47 to 41, it can also be surely prevented that both side walls are pinched by some kind of time and the locking portions 19 are separated from each other and the tightening strength is lowered.

ところで、上記各実施形態の取着体及びナット体２においては、取着部１１の側壁１３及び側壁１４のいずれか一方または双方に、先端が吊りボルト４１の外面に側方から圧接されるビスを取付けてもよい。図１８において、取着部１１の側壁１３及び側壁１４には、上記各実施形態の支持部３１を取付けるためのリベット３２が打ち込まれる位置にねじ孔が設けられ、そのねじ孔には外方からビス３４が螺着されている。ビス３４の先端は吊りボルト４１の外面に側方から当接し、圧接されるようになっている。ここで、ビス３４の先端形状が比較的大きい平面に形成されている場合は、ビス３４の先端は吊りボルト４１のねじ山の頂点と圧接し、先細りの尖った形状に形成されている場合は、吊りボルト４１のねじ溝内に食い込む。なお、ビス３４をリベット３２の打込位置に取着したのは、ビス３４の先端を吊りボルト４１の外面に圧接するためであり、また、ビス３４を使用して支持部３１を取着部１１の側壁に取着するためである。但し、ビス３４は必ずしも支持部３１の取着を兼ねるものでなくてもよく、吊りボルト４１への固定専用のものであってもよい。   By the way, in the attachment body and nut body 2 of each of the embodiments described above, a screw whose tip is pressed against the outer surface of the suspension bolt 41 from one or both of the side wall 13 and the side wall 14 of the attachment portion 11. May be attached. In FIG. 18, the side wall 13 and the side wall 14 of the attachment part 11 are provided with screw holes at positions where rivets 32 for attaching the support parts 31 of the above-described embodiments are driven. Screws 34 are screwed. The tip of the screw 34 is in contact with the outer surface of the suspension bolt 41 from the side and is pressed. Here, when the tip of the screw 34 is formed on a relatively large plane, the tip of the screw 34 is in pressure contact with the apex of the thread of the suspension bolt 41 and is formed in a tapered shape. Then, it bites into the thread groove of the suspension bolt 41. The reason why the screw 34 is attached to the driving position of the rivet 32 is that the tip of the screw 34 is pressed against the outer surface of the suspension bolt 41, and the support portion 31 is attached using the screw 34. It is for attaching to 11 side walls. However, the screw 34 does not necessarily serve to attach the support portion 31, and may be dedicated for fixing to the suspension bolt 41.

このビス３４を取付けることにより、ビス３４の先端は吊りボルト４１の外面に側方から圧接されるため、取着体及びナット体２を吊りボルト４１の所定位置に強固に固定することができ、取着体及びナット体２が吊りボルト４１の軸心を中心に回動するのを確実に防止し、取着体及びナット体２が螺進して吊りボルト４１への取着位置が変動するのを確実に防止することができる。   By attaching the screw 34, the tip of the screw 34 is pressed against the outer surface of the suspension bolt 41 from the side, so that the attachment body and the nut body 2 can be firmly fixed to a predetermined position of the suspension bolt 41. The attachment body and the nut body 2 are reliably prevented from rotating around the axis of the suspension bolt 41, and the attachment body and the nut body 2 are screwed to change the attachment position to the suspension bolt 41. Can be surely prevented.

また、ビス３４の先端を吊りボルト４１の外面に圧接することにより、図１８の矢印で示すように、取着部１１の側壁はビス３４の突張りによる反力を受けて外方に拡開しようとし、それに伴って、吊りボルト４１の挿入空間２１は逆に狭められようとするので、一対の挟持片による挟持力が増し、吊りボルト４１からの取着体の抜脱をより確実に防止することができる。この効果は、ナット体２についても同様である。   Further, by pressing the tip of the screw 34 against the outer surface of the suspension bolt 41, the side wall of the attachment portion 11 expands outward by receiving the reaction force caused by the tension of the screw 34, as shown by the arrow in FIG. 18. In connection with this, the insertion space 21 of the suspension bolt 41 tends to be narrowed conversely, so that the clamping force by the pair of clamping pieces increases, and the attachment body can be more reliably prevented from being detached from the suspension bolt 41. can do. This effect is the same for the nut body 2.

なお、前述したように、取着体の場合は、支持部３１の湾曲部が吊りボルト４１と当接し、ケーブル４２の荷重により吊りボルト４１が取着部１１の挿入開口側１２に押出されて取着体が抜脱するのを防止すべく、支持部３１は取着部１１の側壁において吊りボルト４１の軸心Ｏを通る側方つまり図４(b)の交線Ｌから挿入開口側１２に所定距離離間した位置に取付けるのが望ましい。しかし、ナット体２の場合は、支持部３１を備えていないのであるから、支持部３１の湾曲部が吊りボルト４１と当接することによって抜脱する虞が生ずるという事態は起こらない。また、ビス３４の先端は、吊りボルト４１の軸心Ｏを通る外面の中央に圧接させれば、ナット体２を吊りボルト４１に安定して強固に固定することができる。したがって、これらのことから、ナット体２については、ビス３４は、取着部１１の側壁において、図４(b)の交線Ｌから挿入開口側１２に所定距離離間した位置ではなく、先端が吊りボルト４１の前記中央で圧接することとなる位置で螺着するのが望ましい。   As described above, in the case of the attachment body, the curved portion of the support portion 31 contacts the suspension bolt 41, and the suspension bolt 41 is pushed out to the insertion opening side 12 of the attachment portion 11 by the load of the cable 42. In order to prevent the attachment body from being pulled out, the support portion 31 is located on the side of the attachment portion 11 that passes through the axis O of the suspension bolt 41, that is, from the intersection line L in FIG. It is desirable to attach to a position separated by a predetermined distance. However, in the case of the nut body 2, since the support portion 31 is not provided, there is no possibility that the bending portion of the support portion 31 may come out of contact with the suspension bolt 41. Further, if the tip of the screw 34 is brought into pressure contact with the center of the outer surface passing through the axis O of the suspension bolt 41, the nut body 2 can be stably and firmly fixed to the suspension bolt 41. Therefore, for these nuts 2, the screw 34 is not positioned at a predetermined distance from the intersection line L in FIG. 4 (b) to the insertion opening side 12 on the side wall of the attachment portion 11. It is desirable to screw at the position where the suspension bolt 41 is pressed at the center.

なお、上記各実施形態の取着体１等及びナット体２は、ボルト体として建物の二重天井に垂設された吊りボルト４１に取着するものを示しているが、他に、二重床に立設された高さ調整ボルト等のボルト体にも適用することができる。二重床の高さ調整ボルトの場合、取着体１或いはナット体２をこのボルトの任意の高さに側方から取着し、支持部３１にケーブル４２等を支持させることによりケーブル４２等を二重床の空間内に布設することができる。   In addition, although the attachment body 1 grade | etc., And the nut body 2 of said each embodiment have shown what is attached to the suspending bolt 41 suspended from the double ceiling of a building as a bolt body, The present invention can also be applied to a bolt body such as a height adjusting bolt standing on the floor. In the case of a double floor height adjustment bolt, the attachment body 1 or the nut body 2 is attached to an arbitrary height of the bolt from the side, and the cable 42 and the like are supported by the support portion 31 and the cable 42 and the like Can be laid in a double floor space.
