Description

本発明は、交差する複数の棒状体を連結する交差連結具に関する。   The present invention relates to a cross connector for connecting a plurality of intersecting rod-shaped bodies.

例えば空調機器の室内機や、照明機器、ケーブルラック等の吊設機器は、例えばその四隅にて、第一棒状体を用いて天井スラブ等の構造体から吊設される場合がある。このような場合において、地震等に起因する吊設機器の揺れ動きを抑制するため、注目している1本の第一棒状体から、その両隣に位置する他の第一棒状体に対して交差姿勢で第二棒状体をそれぞれ配設し、これらを相互に連結して補強する場合がある。この場合、第一棒状体とその第一棒状体に対してそれぞれ交差する2本の第二棒状体とを連結する交差連結具が用いられる。   For example, an indoor unit of an air conditioner, a lighting device, a hanging device such as a cable rack may be hung from a structure such as a ceiling slab at the four corners using a first rod-like body. In such a case, in order to suppress the swinging movement of the suspended equipment caused by an earthquake or the like, a crossing posture is taken from one first rod-like body of interest to the other first rod-like bodies located on both sides thereof. In some cases, the second rod-shaped bodies are respectively disposed and connected to each other for reinforcement. In this case, a cross connector that connects the first rod-shaped body and the two second rod-shaped bodies that intersect the first rod-shaped body is used.

このような交差連結具として、例えば特開2014−52014号公報(特許文献1)に記載されたものが知られている(本願の図11も参照)。特許文献1の交差連結具は、吊りボルトPを狭着する狭着体1と、その両端部に連結された一対の斜め支持体3とを備え、斜め支持体3が揺動片3Aと固定片3Bとを有するL字形に屈曲形成されている。そして、吊りボルトPに交差する長ボルトQは、固定片3Bの挿通孔に挿通された状態で一対のナットを用いて両側から締め付けられて固定片3Bに固定されている。   As such a cross-connecting tool, for example, one described in Japanese Patent Application Laid-Open No. 2014-52014 (Patent Document 1) is known (see also FIG. 11 of the present application). The cross connector of Patent Document 1 includes a narrow body 1 for tightly attaching a suspension bolt P and a pair of oblique support bodies 3 connected to both ends thereof, and the oblique support body 3 is fixed to the swing piece 3A. It is bent and formed into an L shape having a piece 3B. And the long volt | bolt Q which cross | intersects the suspension volt | bolt P is clamped from both sides using a pair of nut in the state penetrated by the penetration hole of the fixed piece 3B, and is being fixed to the fixed piece 3B.

特許文献1の交差連結具では、計4ヵ所でナットの締付操作が必要であり、かつ、長ボルトQを固定するのに1本当たり2つのナットの締付操作が必要なので、1本の吊りボルトPと2本の長ボルトQとを連結するのに多くの労力を要する。また、長ボルトQを固定片3Bに固定するには固定片3Bの挿通孔に長ボルトQを挿通させる必要があるところ、例えば長ボルトQが長い場合等にはそのような挿通操作が容易ではない場合もあり、この点からも吊りボルトPと長ボルトQとを連結するのに多くの労力を要する。   In the cross-connecting tool of Patent Document 1, it is necessary to tighten nuts at a total of four locations, and to fasten the long bolt Q, it is necessary to tighten two nuts per one. It takes a lot of labor to connect the suspension bolt P and the two long bolts Q. Further, in order to fix the long bolt Q to the fixing piece 3B, it is necessary to insert the long bolt Q through the insertion hole of the fixing piece 3B. For example, when the long bolt Q is long, such insertion operation is not easy. In some cases, it takes a lot of labor to connect the suspension bolt P and the long bolt Q.

特開2014−52014号公報JP 2014-52014 A

第一棒状体とそれに対して交差する2つの第二棒状体との連結作業を容易に行うことができる交差連結具が望まれる。   There is a demand for a cross connector that can easily perform a connecting operation between the first rod-shaped body and the two second rod-shaped bodies that intersect with the first rod-shaped body.

本発明に係る交差連結具は、
第一棒状体と、前記第一棒状体に対してそれぞれ交差する2本の第二棒状体とを連結する交差連結具であって、
前記第一棒状体を保持する第一保持部と、
前記第一保持部に対して相対変位可能に連結され、かつ、前記第二棒状体のそれぞれの軸方向に沿って対応する第二棒状体を挟み込んで保持する一対の第二保持部と、を備える。
The cross connector according to the present invention is
A cross connector for connecting a first rod-shaped body and two second rod-shaped bodies intersecting the first rod-shaped body,
A first holding part for holding the first rod-like body;
A pair of second holding portions that are connected to the first holding portion so as to be relatively displaceable and hold the corresponding second rod-like bodies sandwiched along the respective axial directions of the second rod-like bodies; Prepare.

この構成によれば、2つの第二保持部がいずれも対応する第二棒状体を挟み込んで保持するので、その保持のための保持操作が容易である。例えば従来仕様の交差連結具のように固定片の孔部に第二棒状体を挿通させる必要がなく、第二棒状体が長い場合であっても
、外周側からその第二棒状体を容易に挟み込んで保持することができる。また、それぞれの第二保持部は、いずれも対応する第二棒状体をその軸方向に沿って挟み込むので、仮保持状態で対応する第二棒状体の軸方向に沿って移動させることができ、各第二保持部の位置調整も容易である。従って、第一棒状体とそれに対して交差する2本の第二棒状体とを相互に連結固定するための連結操作を容易に行うことができる。
According to this configuration, since the two second holding portions sandwich and hold the corresponding second rod-like bodies, the holding operation for the holding is easy. For example, it is not necessary to insert the second rod-like body through the hole of the fixed piece as in the cross connector of the conventional specification, and even if the second rod-like body is long, the second rod-like body can be easily removed from the outer peripheral side. It can be sandwiched and held. In addition, since each second holding portion sandwiches the corresponding second rod-shaped body along its axial direction, it can be moved along the axial direction of the corresponding second rod-shaped body in the temporary holding state, The position adjustment of each second holding part is also easy. Therefore, the connecting operation for connecting and fixing the first rod-shaped body and the two second rod-shaped bodies intersecting with each other can be easily performed.

以下、本発明の好適な態様について説明する。但し、以下に記載する好適な態様例によって、本発明の範囲が限定される訳ではない。   Hereinafter, preferred embodiments of the present invention will be described. However, the scope of the present invention is not limited by the preferred embodiments described below.

1つの態様として、前記第二保持部が、被係止部を有する板状に形成された対象板部と、係止部を有するとともに少なくとも部分的に前記第二棒状体の外周に沿って当該第二棒状体を包囲する包囲部を有する第二保持板部と、前記対象板部の前記被係止部に前記第二保持板部の前記係止部が係止された状態で前記対象板部と前記第二保持板部とを締結固定する第二締結部材と、を有すると好適である。   As one aspect, the second holding portion includes a target plate portion formed in a plate shape having a locked portion, a locking portion, and at least partially along the outer periphery of the second rod-shaped body. A second holding plate having a surrounding portion surrounding the second rod-shaped body; and the target plate in a state where the locking portion of the second holding plate is locked to the locked portion of the target plate. It is preferable to have a second fastening member for fastening and fixing the part and the second holding plate part.

この構成によれば、対象板部と包囲部を有する第二保持板部との間に、第二棒状体の軸方向に沿ってその外周を包囲する状態で第二棒状体を適切に狭着保持することができる。また、対象板部の被係止部と第二保持板部の係止部との係止部位を支点として、単一の第二締結部材を用いて第二棒状体を狭着保持することができ、第二棒状体に対する保持操作自体を、少ない労力でさらに容易に行うことができる。   According to this configuration, the second rod-like body is properly narrowed between the target plate portion and the second holding plate portion having the surrounding portion so as to surround the outer periphery along the axial direction of the second rod-like body. Can be held. Further, the second rod-shaped body can be held tightly using a single second fastening member with the locking portion between the locked portion of the target plate portion and the locking portion of the second holding plate portion as a fulcrum. In addition, the holding operation itself for the second rod-shaped body can be performed more easily with less effort.

1つの態様として、前記第二締結部材が、前記第一保持部と前記第二保持部とを相対変位可能に連結するための枢支連結部材を兼用していると好適である。   As one aspect, it is preferable that the second fastening member also serves as a pivot connecting member for connecting the first holding part and the second holding part so as to be capable of relative displacement.

この構成によれば、部品点数の低減によって低コスト化を図ることができる。また、第二締結部材を不完全に締結させた状態で、第二棒状体の軸方向に沿う第二保持部の移動による位置決めと、第一保持部に対する第二保持部の相対変位による交差角度変更とを、容易に行うことができる。第二保持部の位置決め及び交差角度変更の完了後は、単一の第二締結部材を締結させるだけで、第二保持部による第二棒状体の狭着保持と、交差する2つの棒状体の交差角度の固定とを、一括的に行うことができる。よって、第二棒状体に対する連結作業と2つの棒状体の交差角度変更作業とを、さらに少ない労力で極めて容易に行うことができる。   According to this configuration, the cost can be reduced by reducing the number of parts. In addition, in a state where the second fastening member is incompletely fastened, positioning by movement of the second holding portion along the axial direction of the second rod-shaped body and crossing angle by relative displacement of the second holding portion with respect to the first holding portion Changes can be made easily. After the positioning of the second holding portion and the change of the crossing angle are completed, the second rod-shaped body is held tightly by the second holding portion and the two rod-shaped bodies intersecting each other are simply fastened by a single second fastening member. The intersection angle can be fixed collectively. Therefore, the connecting operation for the second rod-shaped body and the operation for changing the crossing angle of the two rod-shaped bodies can be performed very easily with a smaller amount of labor.

1つの態様として、前記第一保持部が、板状に形成されたベース板部を有し、前記対象板部は、前記ベース板部とは別異の連結板部であり、前記ベース板部の両端部に設けられた取付基部に対して回動自在に連結されていると好適である。   As one aspect, the first holding part has a base plate part formed in a plate shape, the target plate part is a connecting plate part different from the base plate part, and the base plate part It is preferable that it is rotatably connected to attachment bases provided at both ends of the.

Therefore, the connection work can be performed with a high degree of freedom with respect to the work procedure, such as being able to connect the second holding part in a state where the second rod-shaped body is tightly held in advance to the first holding part. In addition, since the mounting base portion of the base plate portion and the connecting plate portion are rotatably connected, the corresponding intersection angle range is relatively wide. In addition, since the second holding unit can be connected to the first holding unit in various relative postures, it is easy to change the posture according to the surrounding environment of the installation site.

1つの態様として、前記第一保持部が、板状に形成されたベース板部を有し、前記対象板部は、前記ベース板部の両端部に設けられた取付基部であり、当該取付基部の前記被係止部が前記第二締結部材の締結位置を中心とする円弧状に形成されていると好適である。   As one aspect, the first holding part has a base plate part formed in a plate shape, and the target plate part is an attachment base part provided at both ends of the base plate part, and the attachment base part It is preferable that the to-be-latched portion is formed in an arc shape centered on the fastening position of the second fastening member.

The first holding portion is disposed along each virtual plane, and the first holding portion surrounds the first rod-shaped body at least partially along the outer periphery of the first rod-shaped body with the base plate portion formed in a plate shape. A first holding plate portion that has an enclosure portion and is fixed to the base plate portion, and a pair of attachment bases provided at both ends of the base plate portion are provided on each of the two virtual planes. It is preferable that the corresponding second holding portion is arranged along the outer surface side of the attachment base portion so as to be capable of relative displacement.

この構成によれば、ベース板部の両端部の取付基部が交差する2つの仮想平面のそれぞれに沿うので、2本の第二棒状体を、2つの仮想平面のそれぞれに沿うように適切に配置することができる。よって、第一棒状体が例えば吊設機器に対する吊部材で、第二棒状体が例えば第一棒状体に対する振止部材であるような構造に、本発明を好適に適用することができる。この場合において、第二保持部が取付基部の外面側(すなわち、仮想平面とは反対側の面側)に連結されるので、取付基部に対する第二保持部の相対変位可能範囲を広く確保することができる。よって、交差する2つの仮想平面の外側領域において2本の第二棒状体が干渉するのを、有効に抑制することができる。   According to this configuration, since the mounting bases at both ends of the base plate part are along the two virtual planes intersecting, the two second rod-shaped bodies are appropriately arranged so as to be along the two virtual planes. can do. Therefore, the present invention can be suitably applied to a structure in which the first rod-shaped body is, for example, a suspension member for a hanging device and the second rod-shaped body is, for example, a bracing member for the first rod-shaped body. In this case, since the second holding portion is connected to the outer surface side of the mounting base portion (that is, the surface side opposite to the imaginary plane), a wide range of relative displacement of the second holding portion with respect to the mounting base portion is ensured. Can do. Therefore, it can suppress effectively that two 2nd rod-shaped bodies interfere in the outer area | region of two crossing virtual planes.

図2〜図5に示すように、第一保持板部40は板状に形成されている。第一保持板部40は、吊りボルト81の軸方向L1に対して略直交する方向に延びる、ベース板部30よりも短い(具体的にはベース本体部31よりもさらに短い)変形帯板状に形成されている。第一保持板部40は、平板状(平坦な板状)に形成された保持本体部41と、この保持本体部41の端部に位置する包囲部44と、この包囲部44における保持本体部41とは反対側の端部に位置する係止片部47とを有する。第一保持板部40を構成する保持本体部41と包囲部44と係止片部47とは、連続して形成されており、言い換えれば、継ぎ目なく一体的に形成されている。   As shown in FIGS. 2-5, the 1st holding | maintenance board part 40 is formed in plate shape. The first holding plate portion 40 is a deformed strip plate shape that is shorter than the base plate portion 30 (specifically, shorter than the base main body portion 31) and extends in a direction substantially orthogonal to the axial direction L1 of the suspension bolt 81. Is formed. The first holding plate portion 40 includes a holding main body portion 41 formed in a flat plate shape (a flat plate shape), a surrounding portion 44 positioned at an end portion of the holding main body portion 41, and a holding main body portion in the surrounding portion 44. 41 has a locking piece 47 located at the end opposite to the end 41. The holding main body portion 41, the surrounding portion 44, and the locking piece portion 47 constituting the first holding plate portion 40 are formed continuously, in other words, they are integrally formed without a seam.

保持本体部41は、当該保持本体部41を板厚方向に貫通する丸穴状(真円状)の挿通孔42を有する。挿通孔42は、保持本体部41の板幅方向(第一保持板部40の延在方向に直交する方向)の中央部に形成されている。この挿通孔42には、第一締結部材39が挿通される。保持本体部41は、その挿通孔42がベース本体部31の挿通孔33と重なる状態で、ベース本体部31に沿って配置される。第一締結部材39の形態次第では、保持本体部41とベース本体部31とが全面的に接する状態で配置されても良い。   The holding main body 41 has a circular hole-like (perfectly circular) insertion hole 42 that penetrates the holding main body 41 in the plate thickness direction. The insertion hole 42 is formed at the center of the holding body 41 in the plate width direction (direction perpendicular to the extending direction of the first holding plate 40). The first fastening member 39 is inserted through the insertion hole 42. The holding main body portion 41 is disposed along the base main body portion 31 with the insertion hole 42 overlapping the insertion hole 33 of the base main body portion 31. Depending on the form of the first fastening member 39, the holding main body portion 41 and the base main body portion 31 may be disposed in a state of being in full contact.

包囲部44は、少なくとも部分的に吊りボルト81の外周に沿って当該吊りボルト81を包囲する。包囲部44は、吊りボルト81の軸方向L1に延びつつ吊りボルト81の周方向の一部(本例では、中心角がおよそ240°の範囲;図3を参照)に沿う、湾曲板状に形成されている。包囲部44は、断面略U字状を呈するように湾曲形成されている。「略U字状」とは、その向きを問わず、U字形状、又は、多少の歪み又は異形部分等があったとしても概略的にはU字とみなすことができる形状を意味する(本明細書において、「略」を用いて表現する他の形状・状態等に関しても同様である)。包囲部44の内面には、位置規制部45が設けられている。位置規制部45は、吊りボルト81の外周面に形成された雄ネジに対して係合可能な、例えば雌ネジや内向き突起等で構成することができる。   The surrounding portion 44 at least partially surrounds the suspension bolt 81 along the outer periphery of the suspension bolt 81. The surrounding portion 44 has a curved plate shape that extends in the axial direction L1 of the suspension bolt 81 and extends along a part of the circumferential direction of the suspension bolt 81 (in this example, the central angle is approximately 240 °; see FIG. 3). Is formed. The surrounding portion 44 is curved so as to exhibit a substantially U-shaped cross section. The “substantially U-shape” means a U-shape, or a shape that can be generally regarded as a U-shape even if there is some distortion or irregular shape, regardless of the orientation (this book). The same applies to other shapes and states expressed using “substantially” in the specification). A position regulating portion 45 is provided on the inner surface of the surrounding portion 44. The position restricting portion 45 can be configured by, for example, a female screw or an inward projection that can be engaged with a male screw formed on the outer peripheral surface of the suspension bolt 81.

係止片部47は、ベース板部30(ベース本体部31)の係止孔32に係止可能な板片
状に形成されている。係止片部47は、保持本体部41及び包囲部44、並びに係止孔32よりも板幅方向の長さが短く形成されている。また、係止片部47は、断面クランク状を呈するように2箇所で屈曲された屈曲片として構成されている。係止片部47は、係止孔32に挿通されて、その先端部がベース本体部31の裏面(保持本体部41及び包囲部44とは反対側の面)に係止される。本実施形態では、係止片部47が第一保持板部40の「係止部」に相当する。
The locking piece portion 47 is formed in a plate piece shape that can be locked in the locking hole 32 of the base plate portion 30 (base body portion 31). The locking piece portion 47 is formed to have a shorter length in the plate width direction than the holding main body portion 41, the surrounding portion 44, and the locking hole 32. Moreover, the latching piece part 47 is comprised as a bending piece bent in two places so that a cross-sectional crank shape may be exhibited. The locking piece portion 47 is inserted into the locking hole 32, and its tip end portion is locked to the back surface of the base main body portion 31 (the surface opposite to the holding main body portion 41 and the surrounding portion 44). In the present embodiment, the locking piece portion 47 corresponds to the “locking portion” of the first holding plate portion 40.

図3及び図4に示すように、第一締結部材39は、互いに螺合される第一ボルト39Aと第一ナット39Bとを有する。本実施形態では、第一ナット39Bとして、かしめナットを用いている。第一ナット39B(かしめナット)を挿通孔33に嵌め込んだ状態で加締め、鍔部と膨出部とでベース板部30(ベース本体部31)を挟み込むことで、第一ナット39Bがベース板部30に固定される。そして、その第一ナット39Bに、挿通孔42に挿通された第一ボルト39Aが締結される。このようにして、第一締結部材39は、ベース板部30の係止孔32に第一保持板部40の係止片部47が係止された状態で、ベース板部30と第一保持板部40とを締結固定する。   As shown in FIGS. 3 and 4, the first fastening member 39 includes a first bolt 39A and a first nut 39B that are screwed together. In the present embodiment, a caulking nut is used as the first nut 39B. The first nut 39B (the caulking nut) is caulked in a state where it is fitted in the insertion hole 33, and the base plate portion 30 (base body portion 31) is sandwiched between the flange portion and the bulging portion, so that the first nut 39B becomes the base. It is fixed to the plate part 30. Then, the first bolt 39A inserted through the insertion hole 42 is fastened to the first nut 39B. In this manner, the first fastening member 39 is connected to the base plate portion 30 and the first holding member in a state where the locking piece portion 47 of the first holding plate portion 40 is locked to the locking hole 32 of the base plate portion 30. The plate part 40 is fastened and fixed.

このように、第一保持部3は、係止孔32を有する板状に形成されたベース板部30と、係止片部47を有するとともに少なくとも部分的に吊りボルト81の外周に沿って当該吊りボルト81を包囲する包囲部44を有する第一保持板部40と、係止孔32に係止片部47が係止された状態でベース板部30と第一保持板部40とを締結固定する第一締結部材39とを備える。この第一保持部3は、吊りボルト81の軸方向L1に沿って、吊りボルト81を容易に挟み込んで狭着保持することができる。本実施形態の第一保持部3は「棒状体保持具2」の一例であり、この場合、ベース板部30が「第一板部」に相当し、第一保持板部40が「第二板部」に相当し、第一締結部材39が「締結部材」に相当する。   As described above, the first holding portion 3 includes the base plate portion 30 formed in a plate shape having the locking holes 32, the locking piece portions 47, and at least partially along the outer periphery of the suspension bolt 81. The first holding plate portion 40 having the surrounding portion 44 surrounding the suspension bolt 81 and the base plate portion 30 and the first holding plate portion 40 are fastened with the locking piece portion 47 locked in the locking hole 32. And a first fastening member 39 to be fixed. The first holding unit 3 can easily sandwich the suspension bolt 81 and hold it tightly along the axial direction L1 of the suspension bolt 81. The first holding part 3 of this embodiment is an example of the “rod-like body holder 2”. In this case, the base plate part 30 corresponds to the “first plate part”, and the first holding plate part 40 is the “second plate part”. The first fastening member 39 corresponds to a “fastening member”.

第一締結部材39の不完全締結状態では、ベース板部30と第一保持板部40とが位置拘束されつつその狭着保持力が十分に発揮されないので、吊りボルト81の軸方向L1に沿って第一保持部3を移動させ、その位置決めを容易に行うことができる。吊りボルト81に対する第一保持部3の位置決めが完了した後は、不完全締結状態にあった第一締結部材39を締め増して完全締結させる。このように、単一の第一締結部材39の締結操作を行うだけで、第一保持部3によるブレースボルト82の狭着保持を容易に行うことができる。   When the first fastening member 39 is in an incompletely fastened state, the base plate portion 30 and the first holding plate portion 40 are restrained in position and the tightly holding force is not sufficiently exhibited. Thus, the first holding part 3 can be moved and positioned easily. After the positioning of the first holding part 3 with respect to the suspension bolt 81 is completed, the first fastening member 39 that has been incompletely fastened is tightened and completely fastened. In this way, the brace bolt 82 can be easily held tightly by the first holding portion 3 only by performing the fastening operation of the single first fastening member 39.

このとき、係止孔32と係止片部47との係止部位は、第一締結部材39と協働して吊りボルト81を狭着保持するための1つの支点となる。よって、吊りボルト81に対する保持操作を、少ない労力で容易に行うことができる。なお、本例では、ベース板部30と第一保持板部40とが締結固定された状態で、第一ナット39Bの鍔部の厚み相当分だけ、ベース板部30のベース本体部31と第一保持板部40の保持本体部41とが微小隙間を隔てて対向配置される。その際、湾曲した包囲部44は、弾性変形によって、保持本体部41をベース本体部31に対する平行姿勢へと容易に変位させるための揺動起点としても機能する(図3を参照)。   At this time, the locking portion between the locking hole 32 and the locking piece portion 47 serves as one fulcrum for tightly holding the suspension bolt 81 in cooperation with the first fastening member 39. Therefore, the holding operation for the suspension bolt 81 can be easily performed with little effort. In this example, in a state where the base plate portion 30 and the first holding plate portion 40 are fastened and fixed, the base body portion 31 and the first main body portion 31 of the base plate portion 30 are equivalent to the thickness of the flange portion of the first nut 39B. The holding main body portion 41 of the one holding plate portion 40 is disposed so as to face the fine gap. At that time, the curved surrounding portion 44 also functions as a swing start point for easily displacing the holding main body portion 41 into a parallel posture with respect to the base main body portion 31 by elastic deformation (see FIG. 3).

図2及び図3に示すように、一対の第二保持部5は、対応するブレースボルト82を保持する。一対の第二保持部5は、第一保持部3に対して相対変位可能に連結され、かつ、2本のブレースボルト82のそれぞれの軸方向L2,L3に沿って対応するブレースボルト82を挟み込んで保持する。本実施形態では、一対の第二保持部5は同一の構成を備えており、以下の説明は、特に明記して区別しない限り、一対の第二保持部5のそれぞれについての言及を意図していることをここに明記する。本実施形態では、第二保持部5は、互いに別異の2つの部材である連結板部50と第二保持板部60とを含むユニットとして
構成されている。第二保持部5は、連結板部50と第二保持板部60とで、ブレースボルト82を挟み込んで狭着保持する。連結板部50と第二保持板部60とは、鉄やステンレス、炭素鋼等の金属材料を用いて構成されており、例えばプレス加工等によって形成することができる。なお、本実施形態では、連結板部50は第一保持部3を構成するベース板部30とは別異の部材であり、この連結板部50が「対象板部」に相当する。
As shown in FIGS. 2 and 3, the pair of second holding portions 5 holds the corresponding brace bolts 82. The pair of second holding portions 5 are connected to the first holding portion 3 so as to be relatively displaceable, and sandwich the corresponding brace bolts 82 along the axial directions L2 and L3 of the two brace bolts 82, respectively. Hold on. In the present embodiment, the pair of second holding portions 5 have the same configuration, and the following description is intended to refer to each of the pair of second holding portions 5 unless otherwise specified. It is clearly stated here. In the present embodiment, the second holding portion 5 is configured as a unit including a connecting plate portion 50 and a second holding plate portion 60 which are two different members.

The connecting plate portion 50 and the second holding plate portion 60 are configured using a metal material such as iron, stainless steel, or carbon steel, and can be formed by, for example, pressing. In the present embodiment, the connecting plate portion 50 is a member different from the base plate portion 30 constituting the first holding portion 3, and the connecting plate portion 50 corresponds to a “target plate portion”.

図2〜図4に示すように、連結板部50は板状に形成されている。連結板部50は、ブレースボルト82の軸方向L2(L3)に対して略略直交する方向に延びる平板状(平坦な板状)の連結本体部51を有する。連結本体部51は、当該連結本体部51を板厚方向に貫通するスリット状の係止孔52を有する。本実施形態では、係止孔52が対象板部としての連結板部30の「被係止部」に相当する。係止孔52は、連結板部50の板幅方向(連結板部50の延在方向に直交する方向であり、本例ではブレースボルト82の軸方向L2(L3)に一致する)に沿って形成されている。この係止孔52には、第二保持板部60の係止片部67が係止される。また、連結本体部51は、当該連結本体部51を板厚方向に貫通する丸穴状(真円状)の挿通孔53を有する。挿通孔53は、連結本体部51の板幅方向の中央部に形成されている。この挿通孔53には、第二締結部材59が挿通される。係止孔52と挿通孔53とは、連結板部50の延在方向の異なる位置に、少なくともブレースボルト82の直径分よりも大きい間隔を隔てて設けられている。また、係止孔52と挿通孔53とは、第二保持部5によって保持されるブレースボルト82の配設位置に対して、両側に分かれて設けられている。   As shown in FIGS. 2-4, the connection board part 50 is formed in plate shape. The connecting plate portion 50 includes a flat plate-like connecting main body portion 51 that extends in a direction substantially orthogonal to the axial direction L2 (L3) of the brace bolt 82. The connection main body 51 has a slit-like locking hole 52 that penetrates the connection main body 51 in the plate thickness direction. In the present embodiment, the locking hole 52 corresponds to the “locked portion” of the connecting plate portion 30 as the target plate portion. The locking hole 52 is along the plate width direction of the connecting plate portion 50 (which is a direction orthogonal to the extending direction of the connecting plate portion 50, and in this example, coincides with the axial direction L2 (L3) of the brace bolt 82). Is formed. The locking piece portion 67 of the second holding plate portion 60 is locked in the locking hole 52. In addition, the connection main body 51 has a round hole (round) insertion hole 53 that penetrates the connection main body 51 in the plate thickness direction. The insertion hole 53 is formed in the central portion of the connection main body 51 in the plate width direction. The second fastening member 59 is inserted through the insertion hole 53.

本実施形態では、第一保持板部40と第二保持板部60とで部品の共通化が図られており、言い換えれば、第二保持板部60は、第一保持部3を構成する第一保持板部40と同一の構成を備えている。以下、第二保持板部60の構成を概略的に説明するが、詳細に関しては第一保持板部40の構成と同様であるものとする。   In the present embodiment, the first holding plate portion 40 and the second holding plate portion 60 share components, in other words, the second holding plate portion 60 is the first holding portion 3 constituting the first holding portion 3. The same structure as the one holding plate 40 is provided. Hereinafter, although the structure of the 2nd holding plate part 60 is demonstrated roughly, it shall be the same as that of the structure of the 1st holding plate part 40 regarding a detail.

図2〜図6に示すように、第二保持板部60は、ブレースボルト82の軸方向L2(L3)に対して略直交する方向に延びる、連結板部50と同程度の長さの変形帯板状に形成されている。第二保持板部60は、一体的に形成された保持本体部61と包囲部64と係止片部67とを有する。保持本体部61は、平板状に形成され、当該保持本体部61を板厚方向に貫通する丸穴状(真円状)の挿通孔62を有する。この挿通孔62には、第二締結部材59が挿通される。保持本体部61は、連結本体部51に対して全面的に接する状態で配置されている。包囲部64は、少なくとも部分的にブレースボルト82の外周に沿って当該ブレースボルト82を包囲するように、略U字状に湾曲形成されている。包囲部64の内面には、雌ネジや内向き突起等からなる位置規制部(図示せず)が設けられている。係止片部67は、連結板部50(連結本体部51)の係止孔52に係止可能な板片状に形成されている。係止片部67は、係止孔52に挿通されて、その先端部が、連結本体部51の裏面(保持本体部61及び包囲部64とは反対側の面)に係止される。本実施形態では、係止片部67が第二保持板部60の「係止部」に相当する。   2-6, the 2nd holding plate part 60 is a deformation | transformation of the length comparable as the connection board part 50 extended in the direction substantially orthogonal to the axial direction L2 (L3) of the brace bolt 82. As shown in FIG. It is formed in a strip shape. The second holding plate portion 60 includes a holding main body portion 61, a surrounding portion 64, and a locking piece portion 67 that are integrally formed. The holding main body portion 61 is formed in a flat plate shape, and has a circular hole-like (perfectly circular) insertion hole 62 that penetrates the holding main body portion 61 in the thickness direction. The second fastening member 59 is inserted through the insertion hole 62. The holding main body portion 61 is disposed in a state of being in full contact with the connection main body portion 51. The surrounding portion 64 is curved and formed in a substantially U shape so as to surround the brace bolt 82 at least partially along the outer periphery of the brace bolt 82. On the inner surface of the surrounding portion 64, a position restricting portion (not shown) made of a female screw, an inward projection or the like is provided. The locking piece portion 67 is formed in a plate piece shape that can be locked in the locking hole 52 of the connecting plate portion 50 (the connecting main body portion 51). The locking piece portion 67 is inserted into the locking hole 52, and its tip end portion is locked to the back surface of the connection main body portion 51 (the surface opposite to the holding main body portion 61 and the surrounding portion 64). In the present embodiment, the locking piece portion 67 corresponds to a “locking portion” of the second holding plate portion 60.

図3及び図4に示すように、第二締結部材59は、互いに螺合される第二ボルト59Aと第二ナット59Bとを有する。本実施形態では、第二ナット59Bとして、第一ナット39Bと同様のかしめナットを用いている。第二締結部材59は、連結板部50の係止孔52に第二保持板部60の係止片部67が係止された状態で、連結板部50と第二保持板部60とを締結固定する。本実施形態では、連結板部50と第二保持板部60とを締結固定するための第二締結部材59が、第一保持部3と第二保持部5とを相対変位可能に連結するための枢支連結部材を兼用している。第二ナット59B(かしめナット)をベース板部30の取付基部35に形成された挿通孔36に嵌め込んだ状態で加締め、鍔部59rと膨出部とで取付基部35を挟み込むことで、第二ナット59Bが取付基部35に固定される。そして、その第二ナット59Bに、第二保持板部60の挿通孔62及び連結板部50
の挿通孔53の両方に挿通された第二ボルト59Aが締結される。これにより、第二締結部材59を用いて、連結板部50と第二保持板部60とを連結しつつ、第一保持部3と第二保持部5とを相対変位可能に連結している。本実施形態では、第二保持部5は、取付基部35の外面35a側に連結されている。
As shown in FIGS. 3 and 4, the second fastening member 59 has a second bolt 59A and a second nut 59B that are screwed together. In the present embodiment, a caulking nut similar to the first nut 39B is used as the second nut 59B. The second fastening member 59 has the connection plate portion 50 and the second holding plate portion 60 in a state where the locking piece portion 67 of the second holding plate portion 60 is locked in the locking hole 52 of the connecting plate portion 50. Fasten and fix. In the present embodiment, the second fastening member 59 for fastening and fixing the connecting plate portion 50 and the second holding plate portion 60 connects the first holding portion 3 and the second holding portion 5 so as to be capable of relative displacement. It also serves as a pivotal connection member. The second nut 59B (caulking nut) is caulked in a state where the second nut 59B (caulking nut) is fitted in the insertion hole 36 formed in the attachment base portion 35 of the base plate portion 30, and the attachment base portion 35 is sandwiched between the flange portion 59r and the bulging portion. The second nut 59B is fixed to the mounting base 35. Then, the insertion hole 62 of the second holding plate portion 60 and the connecting plate portion 50 are provided in the second nut 59B.
The second bolt 59 </ b> A inserted through both of the insertion holes 53 is fastened. Thereby, the 1st holding | maintenance part 3 and the 2nd holding | maintenance part 5 are connected so that relative displacement is possible, connecting the connection board part 50 and the 2nd holding | maintenance board part 60 using the 2nd fastening member 59. FIG. . In the present embodiment, the second holding portion 5 is connected to the outer surface 35 a side of the attachment base portion 35.

このように、第二保持部5は、係止孔52を有する板状に形成された連結板部50と、係止片部67を有するとともに少なくとも部分的にブレースボルト82の外周に沿って当該ブレースボルト82を包囲する包囲部64を有する第二保持板部60と、係止孔52に係止片部67が係止された状態で連結板部50と第二保持板部60とを締結固定する第二締結部材59とを備える。この第二保持部5は、ブレースボルト82の軸方向L2(L3)に沿って、ブレースボルト82を容易に挟み込んで狭着保持することができる。本実施形態の第二保持部5は「棒状体保持具2」の一例であり、この場合、連結板部50が「第一板部」に相当し、第二保持板部60が「第二板部」に相当し、第二締結部材59が「締結部材」に相当する。   As described above, the second holding portion 5 includes the connecting plate portion 50 formed in a plate shape having the locking hole 52 and the locking piece portion 67 and at least partially along the outer periphery of the brace bolt 82. The second holding plate portion 60 having the surrounding portion 64 surrounding the brace bolt 82 and the connecting plate portion 50 and the second holding plate portion 60 are fastened in a state where the locking piece portion 67 is locked in the locking hole 52. And a second fastening member 59 to be fixed. The second holding part 5 can easily sandwich the brace bolt 82 and hold it tightly along the axial direction L2 (L3) of the brace bolt 82. The second holding portion 5 of the present embodiment is an example of the “bar-shaped body holder 2”. In this case, the connecting plate portion 50 corresponds to the “first plate portion”, and the second holding plate portion 60 is the “second plate portion”. The second fastening member 59 corresponds to a “fastening member”.

第二締結部材59の不完全締結状態では、連結板部50と第二保持板部60とが位置拘束されつつその狭着保持力が十分には発揮されないので、ブレースボルト82の軸方向L2(L3)に沿って第二保持部5を移動させ、その位置決めを容易に行うことができる。また、第二締結部材59の不完全締結状態では、第一保持部3と第二保持部5とが位置拘束されつつ非圧接状態に維持されるので、第一保持部3に対して第二保持部5を容易に相対変位させることができる。この第一保持部3に対する第二保持部5の相対変位に伴って、吊りボルト81とブレースボルト82との交差角度変更操作を容易に行うことができる。このように、少なくとも施工の途中段階において位置拘束された状態で相対変位可能なことを含めて、本明細書では「相対変位可能に連結される」と言う。   When the second fastening member 59 is in an incompletely fastened state, the connecting plate portion 50 and the second holding plate portion 60 are restrained in position, but the tightly holding force is not sufficiently exerted, so the axial direction L2 ( The second holding part 5 can be moved along L3) and can be positioned easily. In addition, when the second fastening member 59 is in an incompletely fastened state, the first holding part 3 and the second holding part 5 are maintained in a non-pressure contact state while being restrained in position, so The holding part 5 can be easily displaced relatively. With the relative displacement of the second holding part 5 with respect to the first holding part 3, the crossing angle changing operation of the suspension bolt 81 and the brace bolt 82 can be easily performed. Thus, in this specification, it is said to be “coupled so as to be capable of relative displacement”, including that it can be relatively displaced while being constrained at least in the middle of construction.

ブレースボルト82に対する第二保持部5の位置決めと、吊りボルト81とブレースボルト82との交差角度変更操作が完了した後は、不完全締結状態にあった第二締結部材59を締め増して完全締結させる。このように、単一の第二締結部材59の締結操作を行うだけで、第二保持部5によるブレースボルト82の狭着保持と、吊りボルト81とブレースボルト82の交差角度の固定とを、一括的に行うことができる。   After the positioning of the second holding portion 5 with respect to the brace bolt 82 and the operation of changing the crossing angle between the suspension bolt 81 and the brace bolt 82 are completed, the second fastening member 59 that has been incompletely fastened is tightened to complete fastening. Let In this way, by performing the fastening operation of the single second fastening member 59, the brace bolt 82 is tightly held by the second holding part 5 and the crossing angle of the suspension bolt 81 and the brace bolt 82 is fixed. Can be done in a lump.

このとき、係止孔52と係止片部67との係止部位は、第二締結部材59と協働してブレースボルト82を狭着保持するための1つの支点となる。よって、ブレースボルト82に対する保持操作を、少ない労力で容易に行うことができる。なお、本例では、連結板部50と第二保持板部60とが締結固定された状態で、第二ナット59Bの鍔部59rの厚み相当分だけ、ベース板部30の取付基部35と連結板部50の連結本体部51とが微小隙間Gを隔てて対向配置される(図3を参照)。   At this time, the locking portion between the locking hole 52 and the locking piece 67 serves as one fulcrum for tightly holding the brace bolt 82 in cooperation with the second fastening member 59. Therefore, the holding operation for the brace bolt 82 can be easily performed with little effort. In this example, in a state where the connecting plate portion 50 and the second holding plate portion 60 are fastened and fixed, the connecting portion 35 is connected to the mounting base portion 35 of the base plate portion 30 by an amount corresponding to the thickness of the flange portion 59r of the second nut 59B. The connecting body portion 51 of the plate portion 50 is disposed so as to face the gap G (see FIG. 3).

この微小隙間Gは、係止孔52に係止される係止片部67のうち連結本体部51の裏面側に突出する部分を収納する、突出片部収納空間としても機能する。取付基部35の外面35a側に第二保持部5が連結されていること、及び、上記のような突出片部収納空間(微小隙間G)を有することにより、第二保持部5はベース板部30の両端部の取付基部35に対して全周に亘って回動自在(360°の相対変位が可能)となっている。よって、本実施形態の交差連結具1は、対応可能な交差角度範囲が非常に広く、好都合である。また、第一保持部3に対して様々な相対姿勢で第二保持部5を連結することができるので、設置部位の周囲環境に応じた姿勢変更(例えば、180°の向き変更等)が容易であるという利点がある。   The minute gap G also functions as a protruding piece storage space that stores a portion of the locking piece 67 that is locked to the locking hole 52 that protrudes to the back side of the connecting main body 51. The second holding part 5 is connected to the outer surface 35a side of the mounting base part 35, and the second holding part 5 has the base plate part by having the protruding piece storage space (the minute gap G) as described above. It can be rotated over the entire circumference with respect to the attachment bases 35 at both ends of 30 (relative displacement of 360 ° is possible). Therefore, the cross connector 1 of this embodiment is convenient because the cross angle range that can be handled is very wide. In addition, since the second holding unit 5 can be connected to the first holding unit 3 in various relative postures, it is easy to change the posture according to the surrounding environment of the installation site (for example, 180 ° orientation change). There is an advantage of being.

しかも、第一保持部3に対する第二保持部5の姿勢変更(吊りボルト81とブレースボルト82との交差角度変更を含む)は、第二締結部材59の緩め操作を行って位置及び角
度を調整し、その後、第二締結部材59を締め増して再度完全締結させるだけで良い。従って、本実施形態の交差連結具1によれば、吊りボルト81と2本のブレースボルト82との連結作業、及び、吊りボルト81とブレースボルト82との交差角度変更作業を、非常に容易に行うことができる。そして、4本の吊りボルト81に対して、各スパン84において互いに交差する姿勢で配置される2本のブレースボルト82がそれぞれ交差連結具1で連結されるので、地震等に起因する吊設機器9の揺れ動きを有効に抑制することができる。
Moreover, the posture change of the second holding part 5 with respect to the first holding part 3 (including the change of the crossing angle between the suspension bolt 81 and the brace bolt 82) is performed by loosening the second fastening member 59 to adjust the position and angle. Then, it is only necessary to tighten the second fastening member 59 and completely fasten it again. Therefore, according to the cross connector 1 of the present embodiment, the connection work between the suspension bolt 81 and the two brace bolts 82 and the work for changing the cross angle between the suspension bolt 81 and the brace bolt 82 are very easy. It can be carried out. And, since the two brace bolts 82 arranged in a posture intersecting with each other in each span 84 are connected to the four suspension bolts 81 by the cross connection tool 1, suspension equipment caused by an earthquake or the like 9 can be effectively suppressed.

〔第2の実施形態〕
本発明に係る交差連結具の第2の実施形態について、図面を参照して説明する。本実施形態では、第二保持部5の具体的構成が第1の実施形態とは異なっている。以下、本実施形態の交差連結具1について、主に第1の実施形態との相違点について説明する。なお、特に明記しない点に関しては、第1の実施形態と同様であり、同一の符号を付して詳細な説明は省略する。
[Second Embodiment]
A second embodiment of a cross connector according to the present invention will be described with reference to the drawings. In the present embodiment, the specific configuration of the second holding unit 5 is different from that of the first embodiment. Hereinafter, the difference between the cross connector 1 of the present embodiment and the first embodiment will be mainly described. Note that the points not particularly specified are the same as those in the first embodiment, and the same reference numerals are given and detailed description thereof is omitted.

図7に示すように、本実施形態のベース板部30は、第1の実施形態で説明したベース板部30(図4を参照)に比べて板幅が大きく(幅広に)形成されている。ベース板部30の両端部において当該ベース板部30を屈曲させてなる取付基部35は、略正方形状に形成されている。取付基部35の挿通孔36(この形成位置は、第二締結部材59の締結位置に相当する)は、ベース板部30の延在方向の中心部よりも端縁側に偏倚し、かつ、板幅方向の中心部よりも下方に偏倚した位置に設けられている。   As shown in FIG. 7, the base plate portion 30 of the present embodiment is formed to have a larger plate width (wider) than the base plate portion 30 (see FIG. 4) described in the first embodiment. . The attachment base portion 35 formed by bending the base plate portion 30 at both ends of the base plate portion 30 is formed in a substantially square shape. The insertion hole 36 of the mounting base 35 (this forming position corresponds to the fastening position of the second fastening member 59) is biased to the edge side with respect to the center part in the extending direction of the base plate part 30, and the plate width It is provided at a position biased downward from the center of the direction.

本実施形態では、第一保持部3を構成するベース板部30の取付基部35が、第二保持部5の一部を構成している。より具体的には、取付基部35が、第1の実施形態における連結板部50を兼用しており、ベース板部30の取付基部35と第二保持板部60とを含んで第二保持部5が構成されている。本実施形態では、ベース板部30の取付基部35が「対象板部」に相当する。なお、本実施形態の第二保持部5には第1の実施形態における連結板部50は含まれていない。このような構成では、第一保持部3と第二保持部5とでベース板部30を共有するので、部品点数の低減によって低コスト化を図ることができるという利点がある。   In the present embodiment, the attachment base portion 35 of the base plate portion 30 constituting the first holding portion 3 constitutes a part of the second holding portion 5. More specifically, the mounting base 35 also serves as the connecting plate portion 50 in the first embodiment, and includes the mounting base 35 and the second holding plate 60 of the base plate 30, and the second holding portion. 5 is configured. In the present embodiment, the attachment base portion 35 of the base plate portion 30 corresponds to the “target plate portion”. In addition, the 2nd holding | maintenance part 5 of this embodiment does not include the connection board part 50 in 1st Embodiment. In such a configuration, since the base plate portion 30 is shared by the first holding portion 3 and the second holding portion 5, there is an advantage that the cost can be reduced by reducing the number of parts.

第二保持部5の一部を構成する取付基部35には、円弧状係止孔37が形成されている。円弧状係止孔37は、挿通孔36(第二締結部材59の締結位置)を中心とする円弧状に形成されている。本例では、中心角がおよそ90°の円弧状に形成されている。この円弧状係止孔37には、第二保持板部60の係止片部67が周方向に摺動自在に係止される。そして、第二締結部材59の締結位置を中心とする係止片部67の摺動に伴う第二保持板部60の回動操作によって、吊りボルト81とブレースボルト82との交差角度変更操作を行うことができる。本実施形態の交差連結具1によっても、吊りボルト81と2本のブレースボルト82との連結作業、及び、吊りボルト81とブレースボルト82との交差角度変更作業を、非常に容易に行うことができる。   An arcuate locking hole 37 is formed in the attachment base portion 35 constituting a part of the second holding portion 5. The arc-shaped locking hole 37 is formed in an arc shape centering on the insertion hole 36 (fastening position of the second fastening member 59). In this example, it is formed in an arc shape with a central angle of about 90 °. In the arc-shaped locking hole 37, the locking piece 67 of the second holding plate 60 is locked so as to be slidable in the circumferential direction. Then, the crossing angle changing operation between the suspension bolt 81 and the brace bolt 82 is performed by the turning operation of the second holding plate portion 60 accompanying the sliding of the locking piece portion 67 around the fastening position of the second fastening member 59. It can be carried out. Even with the cross connector 1 of the present embodiment, the connecting work of the suspension bolt 81 and the two brace bolts 82 and the crossing angle changing work of the suspension bolt 81 and the brace bolt 82 can be performed very easily. it can.
