Description

本発明はケーブルを隧道の壁面に沿わせて配線する際に用いる、隧道壁面のケーブル支持装置に関するものである。   The present invention relates to a cable support device for a tunnel wall used when wiring a cable along the wall of the tunnel.

隧道の壁面に所定間隔を存して支持基枠を取付け、該支持基枠の前面板に支持受を着脱自在に取付け、該支持枠にケーブル受支させるようにした構造のものがある（例えば、特許文献１）が、この従来例は、上面が平坦な、支持受の上面に単に載せてケーブルを支持させようとするため、車両の通過によって生じる振動の繰返しによって支持受からケーブルが容易に脱落する虞れがあり、このため、前支持受の上面に凹入部を設け、該凹入部にケーブルを係合して支持枠の基部から先端方向への移動を規制し、脱落に対処したものが提案されている(例えば、特許文献２）。   There is a structure in which a support base frame is attached to a wall surface of a tunnel with a predetermined interval, a support receiver is detachably attached to a front plate of the support base frame, and a cable is supported on the support frame (for example, In this conventional example, the cable has a flat upper surface and is simply placed on the upper surface of the support receiver to support the cable. For this reason, a concave part is provided on the upper surface of the front support receiver, and a cable is engaged with the concave part to restrict the movement of the support frame from the base part to the distal direction, and copes with the dropping. Has been proposed (for example, Patent Document 2).

実開昭６３−６３４号公報Japanese Utility Model Publication No. 63-634 特開２００４−１４０９８５号公報JP 2004-140985 A

前記凹入部を備えた構造のものは、支持受の基部から自由端である先端方向への移動を防ぐという意味では脱落に対処したものであるが、ケーブルに作用する軸線方向の力に対応できず、ケーブルは軸線方向に移動し、支障を来たすことがある。   The structure having the recessed portion copes with dropping in the sense of preventing movement from the base portion of the support support toward the distal end, which is the free end, but can cope with the axial force acting on the cable. First, the cable may move in the axial direction and cause trouble.

本発明は、このような従来例の欠点に着目し、ケーブルの当初の支持状態を確実に保つことのできる装置を提供するために創案したものである。   The present invention has been devised in order to provide an apparatus capable of reliably maintaining the initial support state of the cable, paying attention to the drawbacks of the conventional example.

隧道の内壁面に取付けた支持基枠の前面板に支持受を着脱自在に取付けて突設し、該支持受にケーブルを受止させたケーブル支持装置において、前記前面板と前記支持受の上面板のそれぞれに受止孔を設け、前記前面板側の受止孔に一端の係止片を、前記上面板の受止孔に他の一端の係止片をそれぞれ係離自在に係止した弾性挟持枠の弯曲挟持片に前記ケーブルの一部を係合し、該ケーブルを該弯曲挟持片と前記上面板をそれぞれ圧接させて挟持した構成とするのである。   In a cable support device in which a support receptacle is detachably attached to a front plate of a support base frame attached to an inner wall surface of a tunnel, and a cable is received by the support receptacle, the cable is supported on the front plate and the support receptacle. A receiving hole is provided in each of the face plates, and a locking piece on one end is locked in the receiving hole on the front plate side, and a locking piece on the other end is locked in the receiving hole on the top plate so as to be separable. A part of the cable is engaged with the curved sandwiching piece of the elastic sandwiching frame, and the cable is sandwiched by pressing the curved sandwiching piece and the upper surface plate.

本発明によれば、支持受上にケーブルを載置した状態で弾性挟持枠を、ケーブルを
介して支持基枠と支持受に渡すようにして組付けられるから、ケーブルの支持作業に人手を必要としないことは勿論、ケーブルは支持受と挟持枠とで挟圧されて支持受上に支持されるものであるから、支持受上をケーブルが移動することなく、当初の支持状態を確実に維持できる隧道壁面のケーブル支持装置を提供できる。 According to the present invention, since the elastic holding frame is assembled so as to be passed to the support base frame and the support receiver via the cable in a state where the cable is placed on the support receiver, manpower is required for the cable support operation. Of course, the cable is clamped by the support receiver and the holding frame and is supported on the support receiver, so that the cable is not moved on the support receiver and the initial support state is reliably maintained. It is possible to provide a cable support device for the wall surface of the tunnel.

It is a perspective view which shows the combination relationship of an elastic clamping frame and another member.

図中、１は上下両端の設けた止着部片１ｂ，１ｂにおいてボルトｂで隧道壁面ｗに、横方向に所要間隔を存して固定した支持基枠で、実施例は、金属板を屈曲形成したこの支持基枠１の縦長の前面板１ａに適宜数の取付け部２を上下方向に並べて設け、所望の取付け部２において支持受３と弾性挟持枠４を組付け、ケーブルｃを所要間隔を置いて支持するようにしたものである。   In the figure, reference numeral 1 denotes a support base frame which is fixed to a wall surface w of a tunnel with bolts b at fastening part pieces 1b and 1b provided at both upper and lower ends. In the embodiment, a metal plate is bent. An appropriate number of attachment portions 2 are arranged in the vertical direction on the vertically long front plate 1a of the support base frame 1 formed, and the support receiver 3 and the elastic holding frame 4 are assembled in the desired attachment portion 2, and the cable c is provided at a required interval. It is intended to support by placing.

前記取付け部２は、両端を背面側方向に折曲げて補強部片１ａ´，１ａ´を相対設した前面板１ａに設けた第一乃至第三の各受止孔５，６，７で構成し、前面板１ａの左右方向の中央に第一受止孔５を配してこれに前記弾性挟持枠４の一側に設けた係止片８を係止させるようにし、該第一受止孔５の直下に設けた第二受止孔６には前記支持受３に設けた係止部片９´を係止させるようにし、また、該第二受止孔６の下側の両側に並設した一対の、前記第三受止孔７，７には前記支持受３に設けた掛止部片９´´，９´´を掛止させるようにしたものである。   The mounting portion 2 is composed of first to third receiving holes 5, 6 and 7 provided on the front plate 1a in which both ends are bent in the rear side direction and reinforcing portion pieces 1a 'and 1a' are provided relative to each other. The first receiving hole 5 is arranged at the center in the left-right direction of the front plate 1a so that the locking piece 8 provided on one side of the elastic holding frame 4 is locked to the first receiving hole 5. The second receiving hole 6 provided immediately below the hole 5 is engaged with the engaging piece 9 ′ provided on the support receiver 3, and on both sides below the second receiving hole 6. A pair of juxtaposed third receiving holes 7, 7 are configured to hang engaging pieces 9 ″, 9 ″ provided on the support receiver 3.

支持受３は、金属板を屈曲して成り、前後方向に長い長方形状の上面板９ａの両側に側板９ｂ，９ｂを相対設して構成した主体枠９の前記上面板９ａ（支持受３の上面板でもある）の先端側に、前記弾性挟持枠４の他側に設けた他の係止片１０を係止する受止孔１１を設け、上面板９ａの後端すなわち基端には、ほぼＴ字状の前記係止部片９´を突設し、この係止部片９´の基端縁と基端縁を同面上に位置させた前記掛止部片９´´を、前記側板９ｂの後端すなわち基端に突設して構成し、掛止部片９´´を先部と掛止部とで成る鉤状体としたものである。   The support receiver 3 is formed by bending a metal plate, and the upper surface plate 9a (the support receiver 3 of the support receiver 3) is configured by arranging side plates 9b and 9b on both sides of a rectangular upper surface plate 9a that is long in the front-rear direction. A receiving hole 11 for locking another locking piece 10 provided on the other side of the elastic holding frame 4 is provided on the distal end side of the upper surface plate (which is also an upper surface plate). The latching piece 9 ″ projecting the substantially T-shaped latching piece 9 ′ and having the base edge and the base edge of the latching piece 9 ′ positioned on the same surface, The side plate 9b is configured to project from the rear end or base end of the side plate 9b, and the hooking piece 9 ″ is formed as a bowl-shaped body composed of a tip portion and a hooking portion.

支持受３は、係止部片９´を支持基枠１の取付け部２の第二受止孔６に、掛止部片９´´を第三受止孔７にそれぞれ挿道させ、各部片９´，９´´を各孔６，７に沿って降下させ、各孔６，７の下縁上に載せることにより係止部片９´は第二受止孔６に係止され、係止部片９´´は第三受止孔７に掛止して支持基枠１に取付けられ、その前面板１ａに突設される。   The support receiver 3 is inserted into the second receiving hole 6 of the mounting portion 2 of the supporting base frame 1 and the hooking piece 9 ″ is inserted into the third receiving hole 7 respectively. The pieces 9 ′, 9 ″ are lowered along the holes 6, 7 and placed on the lower edges of the holes 6, 7, so that the locking piece 9 ′ is locked to the second receiving hole 6, The latching piece 9 ″ is hooked on the third receiving hole 7 and attached to the support base frame 1 and protrudes from the front plate 1a.

前記弾性挟持枠４は、上部片４ａと該上部片４ａの先端を折り曲げて連設した前部片４ｂとで成るＬ形枠体で成り、前記上部片４ａの中間部を上方に膨出させて設けた弯曲部１２ａの両端に、上部片４ａを切り起こすようにした円弧状の舌状片１２ｂを延設するようにして設けた弯曲狭持片１２を備え、上部片４ａの自由端すなわち弾性挟持枠４の一端には前記係止片８を、前部片４ｂすなわち弾性挟持枠４の他端には前記係止片１０を設けて構成したものである。   The elastic sandwiching frame 4 is formed of an L-shaped frame composed of an upper piece 4a and a front piece 4b that is formed by bending the tip of the upper piece 4a, and bulges an intermediate portion of the upper piece 4a upward. A curved pinching piece 12 provided so as to extend an arcuate tongue-like piece 12b that cuts and raises the upper piece 4a is provided at both ends of the bent part 12a provided, and the free end of the upper piece 4a, One end of the elastic holding frame 4 is provided with the locking piece 8, and the front piece 4 b, that is, the other end of the elastic holding frame 4 is provided with the locking piece 10.

そして、隧道壁面ｗに固着した前記支持基枠１に片持ち梁状にして支持させた前記支持受３の上面板９ａ上に載せたケーブルｃに弯曲狭持片１２の弯曲部１２ａを係合させるようにして弾性挟持枠４の一方の係止片８を、支持基枠１の前面板１ａに設けた前記第一受止孔５に強制部に挿通させてその縁部において前面板１ａに係止させる一方、弾性挟持枠４の前部片４ｂに突出させた他の後止片１０を弾性変形させて前記受止孔１１に強制部に挿通させてその縁部において、支持受３の上面板９ａに係止させ、ケーブルｃを弯曲挟持片１２と支持受３の上面板９ａとで狭持し、実施例装置を得るのである。   Then, the bent portion 12a of the bent sandwiching piece 12 is engaged with the cable c placed on the upper surface plate 9a of the support receiver 3 supported in a cantilever shape on the support base frame 1 fixed to the wall surface w of the winding path. In this way, one locking piece 8 of the elastic clamping frame 4 is inserted into the first receiving hole 5 provided in the front plate 1a of the support base frame 1 through the forcing portion, and at the edge thereof, the front plate 1a is attached to the front plate 1a. On the other hand, the other back end piece 10 protruded from the front piece 4b of the elastic holding frame 4 is elastically deformed and inserted into the forcible part through the receiving hole 11 at the edge of the support receiver 3 while being locked. The cable c is held between the bent plate 12 and the upper surface plate 9a of the support receiver 3 by being engaged with the upper surface plate 9a to obtain the embodiment device.

尚、弯曲挟持片１２の円弧（弯曲）形と逆方向の円弧（弯曲）形として相対する係合部１３を支持受３の上面板９ａに設けてケーブルｃを係合させてあるが、該係合部１３は支持受３にケーブルｃを載せる際の目印となるもので、本発明の実施する上に必ずしも必要としない。   In addition, although the engaging part 13 provided in the upper surface board 9a of the support receptacle 3 as the circular arc (curved) shape opposite to the circular arc (curved) shape of the curved pinching piece 12 is provided, the cable c is engaged. The engaging portion 13 serves as a mark when the cable c is placed on the support receiver 3 and is not necessarily required for carrying out the present invention.

弯曲挟持片１２の自由端部１２´をケーブルｃから離開する方向に折り曲げてあるのは、弯曲挟持片１２の自由端がケーブルｃにその弾性によって喰い込むのを防ぐためであり、ケーブルｃを挟持枠４の挟持片１２と支持受３の上面板９ａとで挟持枠４側の弾性を利用して長期間挟持させるのであれば、支持片１２の自由端は実施例のような自由端部１２´の形状にしてケーブルｃに圧接させない方が望ましい。   The reason why the free end portion 12 ′ of the bent pinching piece 12 is bent in the direction of separating from the cable c is to prevent the free end of the bent pinching piece 12 from biting into the cable c due to its elasticity. If the holding piece 12 of the holding frame 4 and the upper surface plate 9a of the support receiver 3 are held for a long time using the elasticity of the holding frame 4, the free end of the support piece 12 is a free end portion as in the embodiment. It is desirable that the shape is 12 'and is not pressed against the cable c.
