Description

本発明は、例えばトンネルの壁面に電力や通信用のケーブルを懸架支持するのに好適に用いられるケーブル支持具に関するものである。 The present invention relates to a cable support suitably used for suspending and supporting a power or communication cable on a wall surface of a tunnel, for example.

この種のケーブル支持具として、例えば特許文献１にて開示されているトンネル用ケーブル支持具がある。このトンネル用ケーブル支持具は、トンネル壁面に立掛け状に固定される支持金具と、ケーブルを支持する受け皿とを備えている。
支持金具には、中心線状に沿ってスリットが設けられ、このスリットに対応する係止部が受け皿に設けられている。
そして、支持金具のスリットに受け皿の係止部を挿入して受け皿を９０°回転させることにより、スリットの縁部に係止部が係止されて、支持金具に受け皿が組み付けられるようになっている。 As this type of cable support, for example, there is a tunnel cable support disclosed in Patent Document 1. The cable support for a tunnel includes a support fitting fixed to the tunnel wall surface in a standing manner and a tray for supporting the cable.
The support metal fitting is provided with a slit along the center line, and a catching portion corresponding to the slit is provided on the tray.
Then, by inserting the latching portion of the tray into the slit of the support bracket and rotating the tray by 90 °, the latching portion is latched at the edge of the slit, and the tray is assembled to the support bracket. Yes.

しかし、この特許文献１に係るトンネル用ケーブル支持具では、支持金具に対し受け皿を単に回転させることで組み付けられる構成とされているため、例えばケーブルなどの荷重が受け皿に不均衡に負荷されると、受け皿が容易に回転して受け皿の組付け状態が不安定になる恐れがある。かかる回転防止のために、複数の受け皿を多段的に連続配置して、上下の受け皿同士を互いに掛け止め合う構成とされているが、使用しない受け皿でも組み付ける必要があり、無駄な組み付け作業と無駄な受け皿が生じることになる。つまり、複数段階の高さ位置のうちの所望の高さ位置に所要の受け皿を連続的・間欠的を問わずに組み付けるという組付けの自由度が小さいという問題点がある。 However, since the tunnel cable support according to Patent Document 1 is configured to be assembled by simply rotating the tray with respect to the support bracket, for example, when a load such as a cable is unbalanced on the tray. There is a possibility that the receiving tray rotates easily and the mounting state of the receiving tray becomes unstable. In order to prevent such rotation, a plurality of trays are continuously arranged in multiple stages, and the upper and lower trays are configured to be hooked together. A new saucer will be created. That is, there is a problem in that the degree of freedom of assembly in which a required tray is assembled at a desired height position among a plurality of height positions regardless of whether it is continuous or intermittent.

このような問題点を解決し得るものとして、例えば特許文献２にて提案されているケーブル受金具がある。 As a device that can solve such a problem, there is a cable bracket proposed in Patent Document 2, for example.

図９（ａ）に示されるように、前記特許文献２に係るケーブル受金具１０１は、トンネル壁面Ｔに立掛け状に固定される支持基枠１０２と、ケーブルＫを支持する支持受１０３とを備えている。
図９（ｂ）に示されるように、支持基枠１０２の前面板部１０２ａには、縦方向に所定間隔を存して複数の組付け部１０４が設けられ、これら組付け部１０４を利用することにより、複数段階の高さ位置のうちの所望の高さ位置に所要の支持受１０３を組み付けることができるようになっている。 As shown in FIG. 9A, the cable bracket 101 according to Patent Document 2 includes a support base frame 102 that is fixed to the tunnel wall surface T in a standing manner, and a support bracket 103 that supports the cable K. I have.
As shown in FIG. 9B, the front plate portion 102 a of the support base frame 102 is provided with a plurality of assembly portions 104 at predetermined intervals in the vertical direction, and these assembly portions 104 are used. Thus, the required support receiver 103 can be assembled at a desired height position among the plurality of stages of height positions.

組付け部１０４は、前面板部１０２ａの縦方向に沿う中央に設けられる第一組付孔１０５と、この組付孔１０５よりも下方位置で前面板部１０２ａの左右両側部に設けられる一対の第二組付孔１０６，１０６とにより構成されている。
第一組付孔１０５は、前面板部１０２ａの一部を背面方向に切り起こして設けたもので、下方側の両側部分を切欠き状にして部分的な幅広部１０５ａを備えた縦長方形状を呈するものである。ここで、この第一組付孔１０５の上辺部には、切り起こし片１０７が連設されており、この切り起こし片１０７は、第一組付孔１０５を形成するために切り起こされた前面板部１０２ａの一部で構成されるもので、第一組付孔１０５の長さよりも後述する係止部片１０８のほぼ板厚分だけ短い長方形状に形成されている。
第二組付孔１０６は、第一組付孔１０５よりも小さい縦長の撥形状を呈するものである。 The assembly portion 104 includes a first assembly hole 105 provided in the center along the longitudinal direction of the front plate portion 102 a and a pair of left and right side portions of the front plate portion 102 a at a position below the assembly hole 105. It is comprised by the 2nd assembly hole 106,106.
The first assembly hole 105 is provided by cutting and raising a part of the front plate portion 102a in the back direction, and has a vertical rectangular shape with partial wide portions 105a with both side portions on the lower side cut out. It presents. Here, a cut-and-raised piece 107 is connected to the upper side portion of the first assembly hole 105, and the cut-and-raised piece 107 is formed before the first assembly hole 105 is cut and raised. It is configured by a part of the face plate portion 102a, and is formed in a rectangular shape shorter than the length of the first assembly hole 105 by approximately the plate thickness of a locking portion piece 108 to be described later.
The second assembly hole 106 has a vertically long repellent shape smaller than that of the first assembly hole 105.

図９（ｃ）に示されるように、支持受１０３は、前後方向に長い長方形状の受部片１０３ａの両側に側部片１０３ｂが連設されてなり、受部片１０３の基端部には、頸部とその頸部よりも幅広い係止部とからなる係止部片１０８が突設され、側部片１０３ｂの基端部には、掛止部と先部とかなる鉤形状の掛止部片１０９が突設されている。 As shown in FIG. 9 (c), the support receiver 103 is formed by connecting side pieces 103 b on both sides of a rectangular receiving piece 103 a that is long in the front-rear direction, and at the base end of the receiving piece 103. A locking part piece 108 having a neck part and a wider locking part than the neck part is projected, and a hook-shaped hooking part that is a hook part and a tip part is formed on the base end part of the side piece 103b. A stop piece 109 is projected.

このケーブル受金具１０１においては、係止部片１０８を第一組付孔１０５に幅広部１０５ａを通して挿通させ、第一組付孔１０５に沿って降下させて頸部を幅広部１０５ａ以外の部分に係合させることにより、係止部の両側部が第一組付孔１０５の両縁に係止して支持受１０３の支持基枠１０２との組付け状態が保持される。また、掛止部片１０９を第二組付孔１０６に挿通させて降下させると、掛止部が第二組付孔１０６の下縁に掛止される。
そして、この状態で切り起こし片１０７を第一組付孔１０５に嵌め込むように叩打または押圧させると、切り起こし片１０７の先端部が係止部片１０８に当接して係止部片１０８の第一組付孔１０５からの離脱を防止し、支持基枠１０２との組付け状態を確実に保持することができるようになっている。 In this cable bracket 101, the locking piece 108 is inserted into the first assembly hole 105 through the wide portion 105a, and lowered along the first assembly hole 105 to make the neck portion other than the wide portion 105a. By engaging, both side portions of the locking portion are locked to both edges of the first assembly hole 105 and the assembled state of the support receiver 103 with the support base frame 102 is maintained. Further, when the latching piece 109 is inserted into the second assembly hole 106 and lowered, the latching part is latched on the lower edge of the second assembly hole 106.
In this state, when the cut and raised piece 107 is struck or pressed so as to be fitted into the first assembly hole 105, the tip of the cut and raised piece 107 comes into contact with the locking piece 108 and the locking piece 108 is The detachment from the first assembly hole 105 is prevented, and the assembly state with the support base frame 102 can be reliably maintained.

しかしながら、上記のケーブル受金具１０１では、支持基枠１０２に支持受１０３を組み付ける際に、係止部片１０８を第一組付孔１０５に係止する作業と掛止部片１０９を第二組付孔１０６に掛止する作業とに加えて、切り起こし片１０７を第一組付孔１０５に嵌め込むように叩打または押圧させる作業が必要で手間がかかるため、組付作業性が悪いという問題点がある。
また、ケーブル受金具１０１をトンネル壁面Ｔに取り付け終えた後に支持受１０３の高さ位置を変更したいなどの理由で、既にトンネル壁面Ｔに固定された支持基枠１０２に対して支持受１０３を組み付け直す場合、支持基枠１０２の背面側はトンネル壁面Ｔで塞がれているため、切り起こし片１０７を第一組付孔１０５に嵌め込むように叩打または押圧させることが極めて困難な作業となる。このため、トンネル壁面Ｔに固定された支持基枠１０２を一旦外してからでないと、支持受１０３を組み付け直すことができない。つまり、このケーブル受金具１０１では、ケーブルＫの支持高さ位置の変更を容易に行うことができないという問題点がある。 However, in the cable bracket 101 described above, when the support receiver 103 is assembled to the support base frame 102, the operation of locking the locking portion 108 in the first mounting hole 105 and the hooking piece 109 are set in the second group. In addition to the operation of engaging with the attaching hole 106, the work of striking or pressing the cut and raised piece 107 so as to be fitted into the first attaching hole 105 is necessary and takes time, so that the assembling workability is poor. There is a point.
Further, the support receiver 103 is assembled to the support base frame 102 already fixed to the tunnel wall surface T for the purpose of changing the height position of the support receiver 103 after the cable bracket 101 is attached to the tunnel wall surface T. When repairing, since the back side of the support base frame 102 is closed by the tunnel wall surface T, it is extremely difficult to hit or press the cut and raised piece 107 so as to fit into the first assembly hole 105. . For this reason, the support receiver 103 cannot be reassembled unless the support base frame 102 fixed to the tunnel wall surface T is once removed. That is, the cable bracket 101 has a problem that the support height position of the cable K cannot be easily changed.

本発明は、前述のような問題点に鑑みてなされたもので、組付作業性に優れるとともに、不均衡な負荷や高負荷が作用したとしても組付け状態を安定的に保持することができ、しかもケーブルの支持高さ位置を容易に変更することができるケーブル支持具を提供することを目的とするものである。 The present invention has been made in view of the above-described problems, and is excellent in assembling workability and can stably maintain an assembled state even when an unbalanced load or a high load is applied. And it aims at providing the cable support tool which can change the support height position of a cable easily.

In a cable support comprising a cable stand fixed to a wall surface and a cable receiver that can be assembled to the cable stand at a plurality of height positions and receive the cable,
In the cable receiver, a holding member that supports the cable so as to hold the cable from the lower side and a reinforcing member that supports the holding member are connected to each other so as to generate an elastic repulsive force against a bending operation. ,
Protruding a first locking part piece at the proximal end of the holding member, and projecting a second locking part piece at the proximal end of the reinforcing member,
The cable stand corresponds to a plurality of first openings provided at predetermined intervals in the length direction corresponding to the first locking piece and the second locking piece. A plurality of second openings provided at predetermined intervals in the length direction,
After the first locking portion piece is inserted into the first opening, when the cable receptacle is rotated around the insertion direction, the first locking portion is formed on the side edge of the first opening. The piece is locked,
When the second locking portion piece is inserted into the second opening while the reinforcing member is bent toward the holding member, the first repulsive force of the reinforcing member against the holding member causes the first The second locking piece is locked to the side edge of the second opening (first invention).

本発明において、
前記第１の係止部片は、頸部とその頸部よりも幅広い係止部とからなり、
前記第２の係止部片は、頸部とその頸部よりも幅広い係止部とからなり、かつ前記第１の係止部片と相似形状で一回り小さく形成され、

The first locking part piece comprises a neck part and a locking part wider than the neck part,
The second locking part piece is composed of a neck part and a locking part wider than the neck part, and is formed to be slightly smaller in shape similar to the first locking part piece,
An assembly opening that doubles as the function of the first opening and the second opening is provided,
The assembly opening includes a pair of side portions sandwiching the neck portion of the first locking portion piece and locking both side portions of the locking portion of the first locking portion piece, It is preferable to have a pair of side portions that sandwich the neck portion of the second locking portion piece and lock both side portions of the second locking portion piece (second invention).

本発明において、
前記補強部材の基端部に、前記ケーブル立物の側面に当接可能な横荷重受止部片が突設されるのが好ましい（第３発明）。 In the present invention,
It is preferable that a lateral load receiving piece that can come into contact with the side surface of the cable stand protrudes from the proximal end portion of the reinforcing member (third invention).

本発明においては、ケーブル立物の第１の開口部にケーブル受物の第１の係止部片を挿入後その挿入方向回りにケーブル受物を回動操作することで、第１の開口部の側縁に第１の係止部片が係止される。次いで、ケーブル受物の補強部材を抱持部材に向けて折り曲げ操作しつつケーブル受物の第２の係止部片をケーブル立物の第２の開口部に挿入することにより、抱持部材に対する補強部材の弾性反発力にて第２の開口部の側縁に第２の係止部片が係止される。
第２の開口部の側縁への第２の係止部片の係止状態は、抱持部材に対する補強部材の弾性反発力にて強固に保持される。この第２の開口部の側縁への第２の係止部片の係止状態が解除されない限り、ケーブル受物は回動されないので、第１の開口部からの第１の係止部片の離脱が防止され、ケーブル立物に対するケーブル受物の組付け状態が確実に保持される。
このように、ケーブル受物の第１の係止部片をケーブル立物の第１の開口部に係止する作業と、ケーブル受物の第２の係止部片をケーブル立物の第２の開口部に係止する作業とを実施するだけで、ケーブル立物にケーブル受物を容易に組み付けることができるので、組付作業性に優れるという効果を奏する。 In the present invention, the first opening is obtained by rotating the cable receiver around its insertion direction after inserting the first locking piece of the cable receiver into the first opening of the cable stand. The first locking piece is locked to the side edge. Next, by inserting the second locking portion piece of the cable receptacle into the second opening of the cable stand while bending the reinforcing member of the cable receptacle toward the holding member, The second locking piece is locked to the side edge of the second opening by the elastic repulsive force of the reinforcing member.
The locked state of the second locking piece on the side edge of the second opening is firmly held by the elastic repulsion of the reinforcing member with respect to the holding member. Since the cable receiver is not rotated unless the locking state of the second locking portion piece to the side edge of the second opening is released, the first locking portion piece from the first opening portion is not rotated. Is prevented from being detached, and the assembled state of the cable receiver with respect to the cable stand is reliably maintained.
In this way, the operation of locking the first locking portion of the cable receptacle to the first opening of the cable stand, and the second locking piece of the cable receptacle to the second of the cable stand. Since the cable receptacle can be easily assembled to the cable stand simply by performing the operation of locking in the opening portion, there is an effect that the assembly workability is excellent.

また、例えばケーブルなどの荷重がケーブル受物に不均衡に負荷されたとしても、ケーブル立物の第２の開口部への第２の係止部片の係止状態が解除されない限り、ケーブル受物は回動されないので、ケーブル立物の第１の開口部への第１の係止部片の係止状態が保持されることになり、ケーブル立物に対するケーブル受物の組付け状態を確実に保持することができる。
さらに、ケーブル受物は、ケーブルを直接的に受け止める抱持部材が補強部材によって下側から支えられて補強される構成とされているので、たとえケーブル受物に高負荷が作用したとしても、ケーブル立物に対するケーブル受物の組付け状態を確実に保持することができる。 In addition, even when a load such as a cable is applied to the cable receptacle in an unbalanced manner, the cable receiving portion is not limited as long as the locking state of the second locking portion piece to the second opening of the cable stand is not released. Since the object is not rotated, the locked state of the first locking portion piece to the first opening of the cable stand is maintained, and the assembled state of the cable receiver to the cable stand is ensured. Can be held in.
Furthermore, the cable receiver is configured such that the holding member that directly receives the cable is supported and reinforced by the reinforcing member from below, so even if a high load acts on the cable receiver, the cable receiver The assembled state of the cable receiver with respect to the standing object can be reliably maintained.

また、ケーブル立物を壁面に取り付け終えた後にケーブル受物の高さ位置を変更したいなどの理由で、既に壁面に固定されたケーブル立物に対してケーブル受物を組み付け直す場合、ケーブル受物における補強部材を抱持部材に向けて折り曲げ操作しつつ第２の開口部から第２の係止部片を引き出して第２の開口部に対する第２の係止部片の係止状態を解除し、次いでケーブル受物の回動操作により第１の開口部に対する第１の係止部片の係止状態を解除して第１の開口部から第１の係止部片を引き出すことで、ケーブル立物からケーブル受物を容易に取り外すことができる。
そして、取り外したケーブル受物をケーブル立物に対し所望の高さ位置に配して、第１の係止部片を第１の開口部に係止する作業と、第２の係止部片を第２の開口部に係止する作業とを実施するだけで、ケーブル立物に対するケーブル受物の高さ位置を変更して容易に組み付け直すことができ、ケーブルの支持高さ位置を容易に変更することができる。 Also, if you want to change the height of the cable receptacle after it has been attached to the wall surface, or if you want to reassemble the cable receptacle to the cable stand that has already been fixed to the wall surface, The second locking portion piece is pulled out from the second opening portion while bending the reinforcing member toward the holding member in order to release the locking state of the second locking portion piece with respect to the second opening portion. Then, by releasing the locking state of the first locking portion piece with respect to the first opening by rotating the cable receiver, the first locking portion piece is pulled out from the first opening, The cable receptacle can be easily removed from the standing object.
And the operation | work which distributes the removed cable receptacle in the desired height position with respect to a cable stand, and latches a 1st latching | locking part piece to a 1st opening part, and a 2nd latching | locking part piece By simply performing the operation of locking the cable to the second opening, the height position of the cable receptacle relative to the cable stand can be changed and reassembled easily, and the cable support height position can be easily Can be changed.

第２発明の構成を採用することにより、同一形状の組付用開口部を所要個数、所要ピッチで配置すればよく、第１の係止部片および第２の係止部片のそれぞれに対応させて特別に形状の異なる開口部を設ける必要がなくなり、構造の簡素化を図ることができる。 By adopting the configuration of the second invention, it suffices to arrange the required number of assembly openings of the same shape at the required pitch, corresponding to each of the first locking piece and the second locking piece. Thus, there is no need to provide openings having different shapes, and the structure can be simplified.

第３発明の構成を採用することにより、ケーブル立物に対するケーブル受物の横方向のがたつきを確実に抑えることができる。 By adopting the configuration of the third aspect of the invention, it is possible to reliably suppress the rattling of the cable receptacle relative to the cable stand.

次に、本発明によるケーブル支持具の具体的な実施の形態について、図面を参照しつつ説明する。 Next, specific embodiments of the cable support according to the present invention will be described with reference to the drawings.

〔第１の実施形態〕
図１には、本発明の第１の実施形態に係るケーブル支持具の正面図（ａ）および側面図（ｂ）がそれぞれ示されている。 [First Embodiment]
FIG. 1 shows a front view (a) and a side view (b) of a cable support according to the first embodiment of the present invention.

＜ケーブル支持具の概略構成説明＞
図１（ａ）（ｂ）に示されるケーブル支持具１は、例えばトンネルの内側壁面において水平面と直角を成すトンネル鉛直壁面Ｔに立掛け状に固定されるケーブル立物２と、このケーブル立物２に複数段階の高さ位置に組付可能で例えば電力や通信用のケーブルＫを受け止めるケーブル受物３とを備えている。 <Description of schematic configuration of cable support>
