Description

本発明は、吊りボルト用固定金具及び該金具を用いた構造物に関する。 The present invention relates to a fixing bracket for a hanging bolt and a structure using the bracket.

ビルなどの鉄筋コンクリート製の構造物では、天井面から間隔を開けて室内の天井面を構成する化粧パネルが取り付けられている。天井面と化粧パネルとの間の天井裏空間には、電気・通信用のケーブルや、空調用のダクト、空調設備や照明設備などが配設されている。これらケーブルやダクト、設備などは、コンクリート製の天井面から吊り下げられた吊りボルトを多数設け、吊りボルトと吊りボルトとの間を張り渡している。新設の構造物の場合は、天井用の化粧パネルが貼られていない場合があるが、脚立足場での高所作業となる。既設の構造物の場合は、天井用の化粧パネルが貼られているため、コンクリート造の天井面と化粧パネルとの間の狭い天井裏空間での作業となる。このため、吊りボルトにワンタッチで取り付けられる金具が望まれていた。 In reinforced concrete structures such as buildings, decorative panels that make up the ceiling surface of the room are attached at intervals from the ceiling surface. In the attic space between the ceiling surface and the decorative panel, cables for electricity and communication, ducts for air conditioning, air conditioning equipment, lighting equipment, etc. are arranged. For these cables, ducts, equipment, etc., a large number of hanging bolts suspended from the concrete ceiling surface are provided, and the hanging bolts are stretched between the hanging bolts. In the case of a new structure, the decorative panel for the ceiling may not be attached, but it will be aerial work on the stepladder scaffolding. In the case of an existing structure, since a decorative panel for the ceiling is attached, the work is performed in a narrow space behind the ceiling between the concrete ceiling surface and the decorative panel. Therefore, a metal fitting that can be attached to a hanging bolt with one touch has been desired.

実用新案登録第３１３５３８５号公報Utility Model Registration No. 3135385 Gazette

そこで鋭意研究を重ねた結果、着想を得て図１１に示す試作品の金具２００を製作した。この金具２００は、支持部材２０と、支持部材２０に固定された対をなす螺合部材１２２ａ、１２２ｂと、吊り下げ治具２６とから構成されている。螺合部材１２２ａ、１２２ｂの内面には、吊りボルト１４の軸部１６に形成された雄ネジ１８と螺合させられる雌ネジ２８が形成されている。また、支持部材２０の側面に吊り下げ治具２６を設けている。この金具２００は、吊りボルト１４に対して斜めにして、螺合部材１２２ａと螺合部材１２２ｂとの隙間に吊りボルト１４の軸部１６を通した後、金具２００を吊りボルト１４の軸部１６に沿うように垂直方向に戻して、螺合部材１２２ａ、１２２ｂの雌ネジ２８と吊りボルト１４の雄ネジ１８とを螺合させて、両者を螺着させる。吊り下げ治具２６にワイヤーなどを用いてダクトなどを吊り下げることにより、金具２００に吊りボルト１４に対して反転力（螺合部材１２２ａ、１２２ｂがそれぞれ吊りボルト１４の軸部１６を押圧する方向の力）が加わり、螺合が緊密になる。 Therefore, as a result of repeated diligent research, the prototype metal fitting 200 shown in FIG. 11 was produced based on an idea. The metal fitting 200 is composed of a support member 20, a pair of screwing members 122a and 122b fixed to the support member 20, and a hanging jig 26. On the inner surface of the screwing members 122a and 122b, a female screw 28 to be screwed with the male screw 18 formed on the shaft portion 16 of the hanging bolt 14 is formed. Further, a hanging jig 26 is provided on the side surface of the support member 20. The metal fitting 200 is slanted with respect to the suspension bolt 14, and after passing the shaft portion 16 of the suspension bolt 14 through the gap between the screwing member 122a and the screwing member 122b, the metal fitting 200 is passed through the shaft portion 16 of the suspension bolt 14. The female screw 28 of the screwing members 122a and 122b and the male screw 18 of the hanging bolt 14 are screwed together so as to be screwed together. By suspending a duct or the like on the suspension jig 26 using a wire or the like, a reversing force is applied to the metal fitting 200 against the suspension bolt 14 (directions in which the screwing members 122a and 122b each press the shaft portion 16 of the suspension bolt 14). The force of) is applied, and the screw becomes tight.

ところが、金具２００にダクトなどを吊り下げる作業をしている時、吊り下げ治具２６に下から上方向への力が作用すると、金具２００が吊りボルト１４に対して斜めになり、螺合部材１２２ａ、１２２ｂの雌ネジ２８と吊りボルト１４の雄ネジ１８との螺合が外れてしまい、金具２００が吊りボルト１４から脱落してしまうという問題があることに気が付いた。金具２００を作業者の落下防止に使用している時に、金具２００が突然外れるのは非常に危険である。また、金具２００をダクトや配管・配線の設置のために使用している時に、不意に外れると、作業のやり直しになるという問題があった。そこで、吊りボルト１４に金具２００を取り付けた後は、作業者が故意に外す動作をしない限り外れないようにするために、更に研究を重ねた本発明を想到した。 However, when a duct or the like is suspended from the metal fitting 200 and a force is applied to the hanging jig 26 from the bottom to the top, the metal fitting 200 becomes slanted with respect to the suspension bolt 14 and the screwing member. I noticed that there is a problem that the female screw 28 of 122a and 122b and the male screw 18 of the hanging bolt 14 are disengaged and the metal fitting 200 falls off from the hanging bolt 14. It is very dangerous for the metal fitting 200 to suddenly come off when the metal fitting 200 is used to prevent the operator from falling. Further, when the metal fitting 200 is used for installing ducts, pipes, and wiring, if it is unexpectedly removed, there is a problem that the work must be redone. Therefore, after attaching the metal fitting 200 to the hanging bolt 14, the present invention has been further studied in order to prevent the metal fitting 200 from being removed unless the operator intentionally removes the metal fitting 200.

なお、本願発明者が出願にあたり先願調査をしたところ、特許文献１を見出した。この特許文献１の図1及び図2に示す実施態様は、上記金具２００と基本構成はほぼ同じと言い得るものであるが、本発明者が課題とするところは何ら解決するものではなかった。 In addition, when the inventor of the present application conducted a prior application search before filing an application, Patent Document 1 was found. It can be said that the embodiment shown in FIGS. 1 and 2 of Patent Document 1 has substantially the same basic configuration as the metal fitting 200, but the problem of the present inventor has not been solved at all.

本発明の課題は、吊りボルトにワンタッチで取り付けられ、容易に吊りボルトから脱落し得ない吊りボルト用固定金具を提供することにある。 An object of the present invention is to provide a fixing bracket for a hanging bolt that can be attached to the hanging bolt with one touch and cannot be easily removed from the hanging bolt.

The metal fitting is provided with a support member having a longitudinal direction along the suspension bolt and an inner surface at a position separated from the support member in the longitudinal direction along the male screw formed on the shaft portion of the suspension bolt. A contact member that is arranged in a direction in which the inner surfaces face each other and is arranged at a position that is spaced apart from the diameter of the hanging bolt, and has a female screw that can be screwed with the male screw on either or both of the inner surfaces. The support member is provided with a lock mechanism for locking the suspension bolts arranged between the facing inner surfaces of the contact members so as not to be slanted.

かかる吊りボルト用固定金具において、前記ロック機構は、前記吊りボルトの軸部の進入を許容してロックし、外力によるロックを解除することによって該吊りボルトの軸部を排出できることにある。 In such a fixing bracket for a hanging bolt, the locking mechanism allows the shaft portion of the hanging bolt to enter and locks the fitting, and the shaft portion of the hanging bolt can be discharged by releasing the lock by an external force.

また、かかる吊りボルト用固定金具において、前記ロック機構は、前記吊りボルトを導く並行部と該吊りボルトを定置する底部を備えたＪ字状部材と、該Ｊ字状部材に垂直に形成された回動軸部と、該回動軸部を中心に回動し得て、該吊りボルトを前記並行部に導く傾斜端面と該Ｊ字状部材の底部に位置する吊りボルトと係合する係合端部とを備えた回動部材と、前記回動軸部を中心に該回動部材を付勢する付勢手段とを備えることにある。 Further, in the fixing bracket for the suspension bolt, the lock mechanism is formed vertically to the J-shaped member and a J-shaped member having a parallel portion for guiding the suspension bolt and a bottom portion on which the suspension bolt is placed. Engagement between a rotating shaft portion, an inclined end surface that can rotate around the rotating shaft portion and guides the hanging bolt to the parallel portion, and a hanging bolt located at the bottom of the J-shaped member. A rotating member having an end portion and an urging means for urging the rotating member around the rotating shaft portion are provided.

また、かかる吊りボルト用固定金具において、前記ロック機構は、全部又は一部がバネ性を有する部材から形成され、吊りボルトの軸部により押し広げて収納する傾斜部と収納部とを備えることにある。 Further, in the fixing bracket for the suspension bolt, the lock mechanism is formed of a member having a spring property in whole or in part, and includes an inclined portion and a storage portion which are expanded and stored by the shaft portion of the suspension bolt. is there.

更に、かかる吊りボルト用固定金具において、前記ロック機構は、少なくとも一方の前記当接部材の内面に向き合う位置であって、前記支持部材の裏面から突出し得て、且つ外力により該裏面側に戻す突起体を備えることにある。 Further, in the hanging bolt fixing bracket, the locking mechanism is at a position facing the inner surface of at least one of the contact members, and is a protrusion that can protrude from the back surface of the support member and returns to the back surface side by an external force. To prepare the body.

上記いずれかに記載の吊りボルト用固定金具を用いた構造物であることにある。 It is a structure using the fixing bracket for hanging bolts described in any of the above.

本発明に係る吊りボルト用固定金具によれば、少なくとも一方の内面に雌ネジが形成された当接部材がその内面を向き合うように軸方向（長手方向）に位置をずらせて支持部材に配置されている。２個の当接部材は吊りボルトの軸部が少なくとも通過し得る幅（距離）を開けて配置されているため、吊りボルトの軸部に対して斜めにして２個の当接部材の間に軸部を通させた後、吊りボルト用固定金具を吊りボルトに並行するように垂直方向に引き起こす。この動作によって吊りボルトの雄ネジと当接部材の雌ネジとが螺合させられるが、更に吊りボルトの軸部がロック機構によってロックされ、吊りボルト用固定金具が吊りボルトに対して斜めになることはない。したがって、吊りボルト用固定金具が吊りボルトから不用意に外れることはないため、天井裏などの狭所でのダクトや配管・配線などのための作業を安心して行うことができ、作業性が飛躍的に向上する。しかも、吊りボルト用固定金具をワンタッチで吊りボルトに固定できるため、一層作業性が向上する。 According to the fixing bracket for hanging bolts according to the present invention, the contact member having the female screw formed on at least one inner surface is arranged on the support member by shifting the position in the axial direction (longitudinal direction) so as to face the inner surface. ing. Since the two contact members are arranged so as to have at least a width (distance) through which the shaft portion of the suspension bolt can pass, they are beveled between the two contact members at an angle with respect to the shaft portion of the suspension bolt. After passing the shaft, raise the hanging bolt fixing bracket vertically so as to be parallel to the hanging bolt. By this operation, the male screw of the hanging bolt and the female screw of the contact member are screwed together, but the shaft of the hanging bolt is further locked by the lock mechanism, and the fixing bracket for the hanging bolt becomes slanted with respect to the hanging bolt. There is no such thing. Therefore, since the fixing bracket for the hanging bolt does not come off carelessly from the hanging bolt, work for ducts, piping, wiring, etc. in narrow places such as the ceiling can be performed with confidence, and workability is dramatically improved. Improve. Moreover, since the fixing bracket for the hanging bolt can be fixed to the hanging bolt with one touch, the workability is further improved.

（吊りボルト）
本発明に係る吊りボルト用固定金具（以下「本金具」という。）１０は、図１及び図2に示すように、構造物１２に吊り下げられた吊りボルト１４の任意の箇所に取り付けられる。構造物１２は、ビルやトンネルなどの鉄筋コンクリート製の建造物であることが多いが、これらに限定されるものではない。吊りボルト１４は、軸部１６の表面全体に雄ネジ１８が形成されている。吊りボルト１４の有効径は、吊り下げられる対象物の重量に応じて設定される。吊りボルト１４の材質は、湿度の高い環境で用いられる場合は、ステンレススチールやメッキや防錆処理が施された鋼が選定され、通常は鋼材が使用される。吊りボルト１４は、一端がU字状やL字状に曲げられてコンクリートに埋設固定され、他端が下方に吊り下げられる。 (Hanging bolt)
As shown in FIGS. 1 and 2, the hanging bolt fixing metal fitting (hereinafter referred to as “the main metal fitting”) 10 according to the present invention is attached to an arbitrary position of the hanging bolt 14 suspended from the structure 12. The structure 12 is often a reinforced concrete structure such as a building or a tunnel, but the structure 12 is not limited thereto. The hanging bolt 14 has a male screw 18 formed on the entire surface of the shaft portion 16. The effective diameter of the suspension bolt 14 is set according to the weight of the object to be suspended. When the suspension bolt 14 is used in a high humidity environment, stainless steel or steel with plating or rust prevention treatment is selected, and a steel material is usually used. One end of the hanging bolt 14 is bent into a U-shape or an L-shape to be embedded and fixed in concrete, and the other end is hung downward.

（吊りボルト用固定金具）
本金具１０は、支持部材２０と、対をなす当接部材２２ａ，２２ｂと、ロック機構２４及び吊り下げ治具２６を備えて構成されている。 (Fixing bracket for hanging bolts)
The metal fitting 10 includes a support member 20, a pair of contact members 22a and 22b, a lock mechanism 24, and a hanging jig 26.

（支持部材・当接部材）
支持部材２０は、平面視U字形状をしている。支持部材２０のU字形状の内径寸法は、対をなす半円筒形状の当接部材２２ａ，２２ｂが吊りボルト１４を間に挟んで向き合うように配設されたとき、その当接部材２２ａ，２２ｂが収納できる幅で、その当接部材２２ａ，２２ｂが長手方向に間隔を開けて配設できる長さに設定される。 (Support member / contact member)
The support member 20 has a U-shape in a plan view. The U-shaped inner diameter of the support member 20 is such that when the paired semi-cylindrical contact members 22a and 22b are arranged so as to face each other with the suspension bolt 14 sandwiched between them, the contact members 22a and 22b The contact members 22a and 22b are set to a width that can be accommodated and a length that allows the contact members 22a and 22b to be arranged at intervals in the longitudinal direction.

当接部材２２ａ，２２ｂは、吊りボルト１４の軸部１６と当接する半円筒状の内面には雌ネジ２８が形成されていて、吊りボルト１４の雄ネジ１８と螺合させられる。当接部材２２ａ，２２ｂは支持部材２０の一側端と他側端に雌ネジ２８が形成された内面が向き合う方向に配設されていて、当接部材２２ａと当接部材２２ｂとは軸方向に隙間３０を開けて配設されている。当接部材２２ａの雌ネジ２８と、当接部材２２ｂの雌ネジ２８とはいずれも吊りボルト１４の雄ネジ１８に螺合し得るように、隙間３０の調節がされる。当接部材２２ａ，２２ｂと支持部材２０とは溶接により接合されていて、相応の荷重が負荷されても分離しないようにされている。 The contact members 22a and 22b have a female screw 28 formed on the semi-cylindrical inner surface that comes into contact with the shaft portion 16 of the suspension bolt 14, and are screwed with the male screw 18 of the suspension bolt 14. The abutting members 22a and 22b are arranged in a direction in which the inner surfaces of the support member 20 having female screws 28 formed on one side end and the other side end face each other, and the abutting member 22a and the abutting member 22b are in the axial direction. It is arranged with a gap 30 in between. The gap 30 is adjusted so that the female screw 28 of the abutting member 22a and the female screw 28 of the abutting member 22b can both be screwed into the male screw 18 of the hanging bolt 14. The contact members 22a and 22b and the support member 20 are joined by welding so that they do not separate even when a corresponding load is applied.

当接部材２２ａと当接部材２２ｂとの隙間３０は、図１（ａ）に斜め方向に吊りボルト１４を示すように、吊りボルト１４の軸部１６が通過し得る幅に設定される。ただし、当接部材２２ａ，２２ｂの角部を面取り３２して両当接部材２２ａ，２２ｂを接近させて配置し、本金具１０を全体としてコンパクトにするのが好ましい。当接部材２２ａと当接部材２２ｂとの隙間３０に吊りボルト１４の軸部１６が斜め方向に配置（本金具１０が吊りボルト１４に対して斜めに配置）された後、当接部材２２ａ，２２ｂの雌ネジ２８と吊りボルト１４の軸部１６の雄ネジ１８とが螺合させられるように本金具１０が時計方向に回転させられる。このとき、吊りボルト１４の軸部１６が、支持部材２０の側面と干渉しないように段差３４が形成されている。 The gap 30 between the abutting member 22a and the abutting member 22b is set to a width through which the shaft portion 16 of the hanging bolt 14 can pass, as shown in FIG. 1A in the oblique direction. However, it is preferable that the corners of the contact members 22a and 22b are chamfered 32 and the contact members 22a and 22b are arranged close to each other to make the metal fitting 10 compact as a whole. After the shaft portion 16 of the suspension bolt 14 is diagonally arranged in the gap 30 between the contact member 22a and the contact member 22b (the metal fitting 10 is diagonally arranged with respect to the suspension bolt 14), the contact member 22a, The metal fitting 10 is rotated clockwise so that the female screw 28 of 22b and the male screw 18 of the shaft portion 16 of the hanging bolt 14 are screwed together. At this time, a step 34 is formed so that the shaft portion 16 of the suspension bolt 14 does not interfere with the side surface of the support member 20.

（ロック機構）
支持部材２０の下端部にはロック機構２４が設けられている。ロック機構２４はJ字状部材３６と、そのJ字状部材３６の一端に垂直に形成された軸部３８と、その軸部３８の周りを回動する回動部材４０と、回動部材４０を付勢する付勢手段４２とを備えて構成されている。J字状部材３６は、支持部材２０とその支持部材２０に固定された当接部材２２とに溶接などにより固定されている。図１（ｂ）及び図２（ｂ）に示すように、J字状部材３６は吊りボルト１４の軸部１６を導く並行部４４と並行部４４により導かれてきた軸部１６を定置させる半円弧状の底部４６を備える。したがって、吊りボルト１４の軸部１６はJ字状部材３６の並行部４４に導かれるように両サイドへの動きを規制されて内部へ進入し、底部４６に達して停止する。なお、底部４６の形状は当接部材２２ｂの雌ネジ２８の径よりも大きく形成されている。 (Lock mechanism)
A lock mechanism 24 is provided at the lower end of the support member 20. The lock mechanism 24 includes a J-shaped member 36, a shaft portion 38 formed perpendicularly to one end of the J-shaped member 36, a rotating member 40 that rotates around the shaft portion 38, and a rotating member 40. It is configured to include an urging means 42 for urging. The J-shaped member 36 is fixed to the support member 20 and the abutting member 22 fixed to the support member 20 by welding or the like. As shown in FIGS. 1 (b) and 2 (b), the J-shaped member 36 emplaces the parallel portion 44 that guides the shaft portion 16 of the suspension bolt 14 and the shaft portion 16 that has been guided by the parallel portion 44. It has an arcuate bottom 46. Therefore, the shaft portion 16 of the suspension bolt 14 is restricted from moving to both sides so as to be guided by the parallel portion 44 of the J-shaped member 36, enters the inside, reaches the bottom portion 46, and stops. The shape of the bottom portion 46 is formed to be larger than the diameter of the female screw 28 of the contact member 22b.

J字状部材３６に設けられた回動軸部３８を中心に回動する回動部材４０は、並行部４４を塞ぐように形成された傾斜端部４８と、底部４６に定置させられる吊りボルト１４の軸部１６と係合させられる係合端部５０と、作業者が手で回動させる把手５２とを備える。回動部材４０は、図２（ｂ）において、付勢手段４２により時計回りの方向に回動するように付勢されていて、J字状部材３６の一部と当接して停止させられている。したがって、吊りボルト１４の軸部１６が回動部材４０の傾斜端部４８に当接されて押されると、回動部材４０が付勢手段４２に抗して反時計方向に回動させられる。吊りボルト１４の軸部１６が底部４６に達して停止したとき、回動部材４０の傾斜端部４８は吊りボルト１４の軸部１６との係合から外れ、付勢手段４２により元の位置にまで回動させられ、係合端部５０が吊りボルト１４の軸部１６と係合させられる。次いで、回動部材４０は、作業者が把手５２に指をかけて反時計方向に回動させると、係合端部５０は吊りボルト１４の軸部との係合が解除され、本金具１０は吊りボルト１４に対して斜め方向に動かすことができ、除去できる。なお、J字状部材３６に形成されている窪み５４は、回動部材４０の回動させられる角度を大きくするために形成されている。 The rotating member 40 that rotates around the rotating shaft portion 38 provided on the J-shaped member 36 has an inclined end portion 48 formed so as to close the parallel portion 44 and a hanging bolt that is stationary on the bottom portion 46. It includes an engaging end portion 50 that is engaged with the shaft portion 16 of 14, and a handle 52 that is manually rotated by an operator. In FIG. 2B, the rotating member 40 is urged by the urging means 42 so as to rotate in the clockwise direction, and is stopped by contacting a part of the J-shaped member 36. There is. Therefore, when the shaft portion 16 of the suspension bolt 14 is brought into contact with the inclined end portion 48 of the rotating member 40 and pushed, the rotating member 40 is rotated counterclockwise against the urging means 42. When the shaft portion 16 of the suspension bolt 14 reaches the bottom portion 46 and stops, the inclined end portion 48 of the rotating member 40 is disengaged from the engagement with the shaft portion 16 of the suspension bolt 14, and is returned to the original position by the urging means 42. The engagement end 50 is engaged with the shaft 16 of the suspension bolt 14. Next, when the operator puts a finger on the handle 52 and rotates the rotating member 40 counterclockwise, the engaging end portion 50 is disengaged from the shaft portion of the hanging bolt 14, and the metal fitting 10 is disengaged. Can be moved diagonally with respect to the hanging bolt 14 and can be removed. The recess 54 formed in the J-shaped member 36 is formed to increase the angle at which the rotating member 40 can be rotated.

図１（ａ）に示すように、支持部材２０の側面には、吊り下げ治具２６が溶接などにより固定されている。本実施例における吊り下げ治具２６は、大きく形成された開口部５６にワイヤーなどを通して、ダクトや配線などを吊り下げるために用いられる。吊り下げ治具２６は、その吊り下げ治具２６に荷重が負荷されたとき、当接部材２２ａと当接部材２２ｂがそれぞれ吊りボルト１４の軸部１６に押し付けられる位置に設けられていて、当接部材２２ａ，２２ｂの雌ネジ２８と吊りボルト１４の軸部１６の雄ネジ１８との螺合が一層確実なものとなる。 (Hanging jig)
As shown in FIG. 1A, a hanging jig 26 is fixed to the side surface of the support member 20 by welding or the like. The hanging jig 26 in this embodiment is used for suspending a duct, wiring, or the like by passing a wire or the like through a large opening 56. The hanging jig 26 is provided at a position where the abutting member 22a and the abutting member 22b are respectively pressed against the shaft portion 16 of the hanging bolt 14 when a load is applied to the hanging jig 26. The screwing between the female screw 28 of the contact members 22a and 22b and the male screw 18 of the shaft portion 16 of the suspension bolt 14 becomes more reliable.

（本金具の使用方法）
以上の構成に係る本金具１０は、予め天井などに設置されている吊りボルト１４に取り付けられる。本金具１０を取り付けるべき吊りボルト１４の所定位置に持って行き、本金具１０を斜めにして吊りボルト１４の軸部１６にあてがう。このとき、本金具１０の当接部材２２ａと当接部材２２ｂとの隙間３０に吊りボルト１４の軸部１６が入るように傾ける角度を調節しながら押し込む。吊りボルト１４の軸部１６が隙間３０に入ったのを確認した後、本金具１０を吊りボルト１４の軸部１６に沿うように垂直方向に回転させる。この動作により、吊りボルト１４の軸部１６と本金具１０のロック機構２４の傾斜端部４８とが当接し、回動部材４０が回動させられ、吊りボルト１４の軸部１６がJ字状部材３６の底部４６に達する。このとき、本金具１０の当接部材２２ａ、２２ｂの雌ネジ２８と吊りボルト１４の軸部１６の雄ネジ１８とは螺合させられ、更に吊りボルト１４の軸部１６はロック機構２４における回動部材４０の係合端部５０と係合されて、ロックされる。したがって、本金具１０にあらゆる方向から力を加えても、ロックが解除されて吊りボルト１４から脱落することはない。なお、本金具１０の位置を若干上下させたい場合は、本金具１０を吊りボルト１４に対して回転させることにより、上下させることができる。また、大きく位置を変えたい場合や取り外したい場合は、ロック機構２４における回動部材４０に形成された把手５２を持ち上げるように回動させて、係合端部５０と吊りボルト１４の軸部１６との係合を解除することにより、直ちに本金具１０を吊りボルト１４から外すことができる。 (How to use this metal fitting)
The metal fitting 10 according to the above configuration is attached to a hanging bolt 14 previously installed on the ceiling or the like. Bring the metal fitting 10 to a predetermined position of the hanging bolt 14 to which the metal fitting 10 is to be attached, and apply the metal fitting 10 to the shaft portion 16 of the suspension bolt 14 at an angle. At this time, the shaft portion 16 of the suspension bolt 14 is pushed into the gap 30 between the contact member 22a and the contact member 22b of the metal fitting 10 while adjusting the tilt angle. After confirming that the shaft portion 16 of the suspension bolt 14 has entered the gap 30, the metal fitting 10 is rotated in the vertical direction along the shaft portion 16 of the suspension bolt 14. By this operation, the shaft portion 16 of the suspension bolt 14 and the inclined end portion 48 of the lock mechanism 24 of the metal fitting 10 come into contact with each other, the rotating member 40 is rotated, and the shaft portion 16 of the suspension bolt 14 has a J shape. It reaches the bottom 46 of the member 36. At this time, the female screw 28 of the contact members 22a and 22b of the metal fitting 10 and the male screw 18 of the shaft portion 16 of the suspension bolt 14 are screwed together, and the shaft portion 16 of the suspension bolt 14 is rotated by the lock mechanism 24. It is engaged and locked with the engaging end 50 of the moving member 40. Therefore, even if a force is applied to the metal fitting 10 from all directions, the lock is released and the metal fitting 10 is not dropped from the hanging bolt 14. If the position of the metal fitting 10 is to be slightly moved up and down, the metal fitting 10 can be moved up and down by rotating the metal fitting 10 with respect to the hanging bolt 14. Further, when it is desired to change the position significantly or to remove it, the handle 52 formed on the rotating member 40 of the lock mechanism 24 is rotated so as to be lifted, and the engaging end portion 50 and the shaft portion 16 of the suspension bolt 14 are rotated. By disengaging the engagement with the metal fitting 10, the metal fitting 10 can be immediately removed from the suspension bolt 14.

（効果）
この操作は、片手でのワンタッチでできるので、天井裏などの狭小空間であっても、作業性が大幅に向上する。 (effect)
Since this operation can be performed with one touch with one hand, workability is greatly improved even in a narrow space such as the ceiling.

（他の実施態様）
次に、本発明に係る他の実施態様を説明する。以下の説明において、上記実施態様と同様の構成については、同じ符号を付すことにとって説明を省略する場合がある。 (Other embodiments)
Next, another embodiment according to the present invention will be described. In the following description, the same configurations as those in the above embodiment may be omitted by the same reference numerals.

（他の実施態様１）
図３に示すように、本金具５８は、支持部材６０、当接部材６２ａ、６２ｂ及び吊り下げ治具６４を一体的に形成しても良い。この場合、本金具５８は金属のブロックを切り出して、当接部材６２ａ、６２ｂとなる部分に下穴を形成した後、その下穴に雌ネジをネジきりする。その後、隙間６６となる箇所と、当接部材６２ａ、６２ｂとなるように雌ネジの部分を切削で切り開く。また、吊り下げ治具６４についても、切削により一体的に形成する。また、ロック機構として、本金具５８を吊りボルト１４に取り付けたとき、吊りボルト１４の軸部１６に接する支持部材６０の位置に、換言すると当接部材６２ｂの内面に当接するように配設された軸部１６を間に挟んだ支持部材６０の位置に雄ネジ６８を挿通させる。すなわち、本金具５８の当接部材６２ａ、６２ｂに吊りボルト１４を螺合させた後、雄ネジ（突起体）６８をねじ込み、雄ネジ６８の軸部６９で吊りボルト１４の軸部１６がその軸と直角方向に動かないように抑え込む。吊りボルト１４から本金具５８を取り外すときは、雄ネジ６８を支持部材６０から突出しないように、引っ込めることにより、容易に行うことができる。 (Other Embodiment 1)
As shown in FIG. 3, the metal fitting 58 may integrally form the support member 60, the contact members 62a and 62b, and the hanging jig 64. In this case, the metal fitting 58 cuts out a metal block to form a pilot hole in the portion to be the contact members 62a and 62b, and then screw a female screw into the pilot hole. After that, the portion where the gap 66 is formed and the portion of the female screw are cut open so as to be the contact members 62a and 62b. Further, the hanging jig 64 is also integrally formed by cutting. Further, as a locking mechanism, when the metal fitting 58 is attached to the suspension bolt 14, it is arranged at the position of the support member 60 in contact with the shaft portion 16 of the suspension bolt 14, in other words, so as to abut on the inner surface of the contact member 62b. A male screw 68 is inserted at the position of the support member 60 sandwiching the shaft portion 16 in between. That is, after the suspension bolt 14 is screwed into the contact members 62a and 62b of the metal fitting 58, the male screw (projection) 68 is screwed in, and the shaft portion 16 of the suspension bolt 14 is screwed into the shaft portion 69 of the male screw 68. Hold it down so that it does not move in the direction perpendicular to the axis. The metal fitting 58 can be easily removed from the hanging bolt 14 by retracting the male screw 68 so as not to protrude from the support member 60.

かかる実施態様において、ロック機構である雄ネジ６８をスライド部材（突起体）とし、このスライド部材と支持部材６０との接触部にゴムや樹脂などからなる抵抗部材を設けても良い。すなわち、吊りボルト１４に本金具５８を取り付けたとき、スライド部材を抵抗部材の抵抗力に抗して押し込み、スライド部材の軸部と本金具５８の当接部材６２ｂとの間に吊りボルト１４の軸部１６を挟みこんで固定する。また、吊りボルト１４から本金具５８を取り除くときは、スライド部材を支持部材から突出しないように引き抜くことで行うことができる。 In such an embodiment, the male screw 68, which is a locking mechanism, may be used as a slide member (projection), and a resistance member made of rubber, resin, or the like may be provided at a contact portion between the slide member and the support member 60. That is, when the metal fitting 58 is attached to the suspension bolt 14, the slide member is pushed against the resistance force of the resistance member, and the suspension bolt 14 is placed between the shaft portion of the slide member and the contact member 62b of the metal fitting 58. The shaft portion 16 is sandwiched and fixed. Further, when removing the metal fitting 58 from the suspension bolt 14, the slide member can be pulled out so as not to protrude from the support member.

この本金具５８は、切削等の加工に時間が掛かるが、当接部材６２ａの雌ネジと、当接部材６２ｂの雌ネジとがピッチが合うように、支持部材６０に当接部材６２ａ、６２ｂを接合する手間がなくなる。 Although it takes time to perform processing such as cutting, the metal fitting 58 is attached to the support member 60 so that the female screw of the contact member 62a and the female screw of the contact member 62b are aligned with each other. Eliminates the hassle of joining.

（他の実施態様２）
次に、図４に示すように、本金具８６は、支持部材８８と吊り下げ治具２６とを鋼板をレーザー加工や打ち抜き加工などにより同時に一体的に形成し、支持部材８８部分に当接部材９０ａ、９０ｂ及びロック機構２４を溶接により固着することによって構成しても良い。当接部材９０ａ、９０ｂは、４角柱の金属ブロックに下穴をあけた後、吊りボルト１４の雄ネジ１８に螺合し得る雌ネジ２８にタップを立て、次いで雌ネジ２８の軸心を含む平面で切断して、製造される。得られた当接部材９０ａ、９０ｂは、支持部材８８の所定の位置に配置して、溶接して固定される。また、ロック機構２４は図１及び図２に示すものと同じ構成のものを予め組み立てておき、支持部材８８に溶接などにより固定される。 (Other Embodiment 2)
Next, as shown in FIG. 4, in the metal fitting 86, the support member 88 and the hanging jig 26 are integrally formed of the steel plate by laser machining, punching, etc. at the same time, and the support member 88 is contacted with the contact member. The 90a, 90b and the lock mechanism 24 may be fixed by welding. The abutting members 90a and 90b include a pilot hole in a metal block of a quadrangular prism, tapped on a female screw 28 that can be screwed into a male screw 18 of a hanging bolt 14, and then include an axial center of the female screw 28. Manufactured by cutting on a flat surface. The obtained contact members 90a and 90b are arranged at predetermined positions of the support member 88 and welded and fixed. Further, the lock mechanism 24 has the same configuration as that shown in FIGS. 1 and 2 and is assembled in advance and fixed to the support member 88 by welding or the like.

このようにして得られた本金具８６は、上記図１等に示す実施態様と比較して部品点数と加工工数が少なく、安価に得られる。ただし、本金具８６の作用効果は上記実施態様と全く同じである。 The metal fitting 86 thus obtained has a smaller number of parts and man-hours for processing as compared with the embodiment shown in FIG. 1 and the like, and can be obtained at low cost. However, the action and effect of the metal fitting 86 is exactly the same as that of the above embodiment.

（他の実施態様３）
また、図５に示すように、吊り下げ治具としてフック９２を利用することも可能である。フック９２の側面に本金具９４の支持部材を溶接などにより固着しても良く、あるいはフック９２の側面を支持部材として直接、当接部材９０ａ、９０ｂとロック機構２４を固着しても良い。フック９２には、図示しないチェーンブロックが設けられているのが好ましい。この場合、フック９２をひっかける金具がなく、吊りボルト１４しかない場合は、本金具９４を用いて吊りボルト１４にチェーンブロックを取り付けることができる。なお、フック９２に限定されるものではなく、たとえばＣカンなどの側面に本金具９４を形成しても良い。 (Other Embodiment 3)
Further, as shown in FIG. 5, it is also possible to use the hook 92 as a hanging jig. The support member of the metal fitting 94 may be fixed to the side surface of the hook 92 by welding or the like, or the contact members 90a and 90b and the lock mechanism 24 may be directly fixed to the side surface of the hook 92 as the support member. The hook 92 is preferably provided with a chain block (not shown). In this case, if there is no metal fitting for hooking the hook 92 and there is only a hanging bolt 14, the chain block can be attached to the hanging bolt 14 by using the metal fitting 94. The metal fitting 94 is not limited to the hook 92, and the metal fitting 94 may be formed on the side surface of, for example, a C-can.

（他の実施態様４）
更に、本金具に取り付けられる吊り下げ治具は図１等に示す形状のものに限定されるものではない。たとえば、図６に示すように、吊り下げ治具８０はロック機構２４のJ字状部材３６と一体的に形成された金属プレート８１にボルト孔を設け、そのボルト孔にボルト８２を通してナット８４で螺着した構成とする。ボルト８２の下端部にダクトや配管などを取り付け、高さ調節はナット８４を緩めて、上下方向の調節を行う。 (Other Embodiment 4)
Further, the hanging jig attached to the metal fitting is not limited to the shape shown in FIG. 1 and the like. For example, as shown in FIG. 6, the hanging jig 80 is provided with a bolt hole in a metal plate 81 integrally formed with a J-shaped member 36 of the lock mechanism 24, and a bolt 82 is passed through the bolt hole with a nut 84. It shall be a screwed configuration. A duct, piping, or the like is attached to the lower end of the bolt 82, and the height is adjusted by loosening the nut 84 and adjusting in the vertical direction.

（他の実施態様５）
更に、図７及び図８に示すように、本金具９６の支持部材としてＬ字鋼９８を用いることができる。Ｌ字鋼９８の一端には当接部材９０ａ、９０ｂが固定され、その他端にはロック機構１００が設けられる。ロック機構１００は、吊りボルト１４の軸部１６を受ける半円形の内面１０２を備えた受台１０４と、その受台１０４を貫通する孔に一端に雄ネジ１０６、他端にＪ字状に曲げられた押さえ部１０８が形成された押さえ部材１１０を備えている。受台１０４の内面１０２には、雌ネジが形成されていても良い。 (Other Embodiment 5)
Further, as shown in FIGS. 7 and 8, L-shaped steel 98 can be used as a support member for the metal fitting 96. Contact members 90a and 90b are fixed to one end of the L-shaped steel 98, and a lock mechanism 100 is provided at the other end. The lock mechanism 100 has a pedestal 104 having a semi-circular inner surface 102 that receives the shaft portion 16 of the suspension bolt 14, and a male screw 106 at one end and a J-shape at the other end in a hole penetrating the pedestal 104. A pressing member 110 on which the pressed pressing portion 108 is formed is provided. A female screw may be formed on the inner surface 102 of the cradle 104.

本金具９６は、吊りボルト１４に対して斜めにして当接部材９０ａと当接部材９０ｂとの間の隙間１１２に吊りボルト１４を通した後、Ｌ字鋼（支持部材）９８を吊りボルト１４の方向にすることにより、当接部材９０ａと当接部材９０ｂとの間に吊りボルト１４を挟みこむようにする。次いで、吊りボルト１４の先端側をロック機構１００の受台１０４の上に移動させ、内面１０２に吊りボルト１４の軸部１６を載せる。その後、押さえ部材１１０の押さえ部１０８により、吊りボルト１４の軸部１６を雄ネジ１０６に設けられたナット１１２を締め付けて内面１０２に押さえ込む。これにより、本金具９６はナット１１２を緩めないかぎり、吊りボルト１４から外れることはない。 The metal fitting 96 passes the suspension bolt 14 through the gap 112 between the contact member 90a and the contact member 90b at an angle with respect to the suspension bolt 14, and then passes the L-shaped steel (support member) 98 through the suspension bolt 14. The suspension bolt 14 is sandwiched between the abutting member 90a and the abutting member 90b. Next, the tip end side of the suspension bolt 14 is moved onto the pedestal 104 of the lock mechanism 100, and the shaft portion 16 of the suspension bolt 14 is placed on the inner surface 102. After that, the shaft portion 16 of the suspension bolt 14 is pressed against the inner surface 102 by tightening the nut 112 provided on the male screw 106 by the pressing portion 108 of the pressing member 110. As a result, the metal fitting 96 does not come off from the hanging bolt 14 unless the nut 112 is loosened.

本金具９６のＬ字鋼（支持部材）９８には、図７に示すようなフック形状を備えた部材１１４や、図８に示すようなＵ字状の金具１１６を設け、複数の配管あるいは配線を併設することができる。 The L-shaped steel (support member) 98 of the metal fitting 96 is provided with a member 114 having a hook shape as shown in FIG. 7 and a U-shaped metal fitting 116 as shown in FIG. 8, and a plurality of pipes or wirings are provided. Can be added.

（他の実施態様６）
次に、図９に示すように、本金具７０は、当接部材７２ａ、７２ｂのうちたとえば当接部材７２ａにのみ雌ネジ２８を形成し、当接部材７２ｂには雌ネジを形成しない構成とすることも可能である。上述の実施態様は重量物を吊り下げるために、当接部材２２ａ，２２ｂのいずれにも雌ネジ２８を形成していたが、軽量物である場合には一方の当接部材７２ａに雌ネジを形成するだけでも良い。本金具７０は、吊りボルト１４の雄ネジ１８と当接部材７２ａの雌ネジ２８とが螺合する面（螺合面）のせん断力で吊り下げ力が定まる。すなわち、半円筒状の螺合面の面積が大きければ、そのせん断力は大きくなり、吊り下げ力も大きくなる。本金具７０で吊り下げるダクトや配管などの重量が小さい場合は、たとえば当接部材７２ａにのみ雌ネジ２８を形成する構成で、充分に吊り下げ力に耐えうる。このように、たとえば当接部材７２ａにのみ雌ネジ２８を形成し、当接部材７２ｂには雌ネジを形成しない構成とすることにより、当接部材７２ｂは、当接部材７２ａの雌ネジ２８のピッチと合わせる必要がなくなり、本金具７０の製造コストを下げることが可能となる。 (Other Embodiment 6)
Next, as shown in FIG. 9, the metal fitting 70 has a configuration in which the female screw 28 is formed only on, for example, the contact member 72a of the contact members 72a and 72b, and the female screw is not formed on the contact member 72b. It is also possible to do. In the above-described embodiment, the female screw 28 is formed on each of the contact members 22a and 22b in order to suspend a heavy object, but in the case of a lightweight object, a female screw is formed on one of the contact members 72a. It may just be formed. The hanging force of the metal fitting 70 is determined by the shearing force of the surface (screwed surface) where the male screw 18 of the hanging bolt 14 and the female screw 28 of the contact member 72a are screwed together. That is, if the area of the semi-cylindrical screw surface is large, the shearing force is large and the hanging force is also large. When the weight of the duct or pipe suspended by the metal fitting 70 is small, for example, the female screw 28 is formed only on the contact member 72a, so that the suspension force can be sufficiently withstood. In this way, for example, by forming the female screw 28 only on the contact member 72a and not forming the female screw on the contact member 72b, the contact member 72b can be formed on the female screw 28 of the contact member 72a. It is not necessary to match the pitch, and the manufacturing cost of the metal fitting 70 can be reduced.

本金具７０において、当接部材７２ａの長さを長くする、すなわち当接部材７２ａの雌ネジ２８の長さを長くすることにより、吊り下げ力を大きくすることが可能となる。また、雌ネジを形成していない当接部材７２ｂは、吊りボルト１４の軸部１６を押さえる作用をするだけであるため、長さは短くても良い。吊りボルト１４の軸部１６を当接部材７２ａ、当接部材７２ｂ及びロック機構２４の係合端部５０の３点で支持して、吊りボルト１４の軸心に対して直角方向に本金具７０が動かないようになっていれば当接部材７２ｂの長さは問題にならない。更に、当接部材７２ａには雌ネジを形成しないで、当接部材７２ｂに雌ネジを設ける構成としても良い。 In the metal fitting 70, the hanging force can be increased by increasing the length of the contact member 72a, that is, increasing the length of the female screw 28 of the contact member 72a. Further, since the contact member 72b on which the female screw is not formed only acts to press the shaft portion 16 of the suspension bolt 14, the length may be short. The shaft portion 16 of the suspension bolt 14 is supported by the contact member 72a, the contact member 72b, and the engaging end portion 50 of the lock mechanism 24, and the metal fitting 70 is perpendicular to the axis of the suspension bolt 14. The length of the contact member 72b does not matter as long as it does not move. Further, the female screw may be provided on the contact member 72b without forming the female screw on the contact member 72a.

（他の実施態様７）
ロック機構は吊りボルト１４の軸部１６に２か所の当接部材をそれぞれ向き合う方向に当接させたとき、同時にロック機構により軸部１６をロックして、交互に3点で支持できれば良い。ロック機構は上述の実施態様に限定されるものではなく、たとえば図１０に示す構成でも良い。すなわち、支持部材２０の一端にバネ鋼からなる把持部材７４でロック機構を構成することができる。把持部材７４は、吊りボルト１４の軸部１６を把持する把持部７５と、その把持部７５に軸部１６を導き、把持部７５を押し広げる傾斜部７６と、一体的に形成された把持部７５と傾斜部７６とを支持部材２０に固定する固定部７７を備えて構成される。固定部７７は支持部材２０に溶接で固定するのが好ましい。把持部７５が吊りボルト１４の軸部１６を把持した後、容易に把持部７５から軸部１６が出ないようにするのが好ましい。図示を省略するが、たとえば２つの傾斜部７６をワイヤーなどで連結して拡がらないようにしたり、傾斜部７６と固定部７７との連結部に孔を開け、ワイヤーを通して締結しておくのが好ましい。 (Other Embodiment 7)
As for the lock mechanism, when two contact members are brought into contact with the shaft portion 16 of the suspension bolt 14 in the directions facing each other, the shaft portion 16 may be locked by the lock mechanism at the same time and can be alternately supported at three points. The locking mechanism is not limited to the above-described embodiment, and may be configured as shown in FIG. 10, for example. That is, the lock mechanism can be configured by a grip member 74 made of spring steel at one end of the support member 20. The grip member 74 is integrally formed with a grip portion 75 that grips the shaft portion 16 of the suspension bolt 14, and an inclined portion 76 that guides the shaft portion 16 to the grip portion 75 and spreads the grip portion 75. It is configured to include a fixing portion 77 for fixing the 75 and the inclined portion 76 to the support member 20. The fixing portion 77 is preferably fixed to the support member 20 by welding. It is preferable that the shaft portion 16 does not easily come out from the grip portion 75 after the grip portion 75 grips the shaft portion 16 of the suspension bolt 14. Although not shown, for example, it is possible to connect the two inclined portions 76 with a wire or the like to prevent them from expanding, or to make a hole in the connecting portion between the inclined portion 76 and the fixing portion 77 and fasten them through the wire. preferable.

A structure can be made by using the above-mentioned various metal fittings. That is, it is possible to lay ducts, wirings, pipes, etc. arranged on each floor of a building or tunnels of various sizes. By using this metal fitting, the work efficiency of the laying work can be improved, the work schedule can be shortened, and the cost associated with the construction of the structure can be reduced as a whole.
