親桁は、車両進行方向に沿って延びるように設置部上に複数設けてあり、それぞれの端部どうしをボルトや連結板を介して連結していた。例えば親桁どうしの連結をボルトによって行う場合は、通常、一対の親桁における片側の親桁につき２本のボルトで連結していた。即ち、一対の親桁どうしを連結する際には４本のボルトを使用することとなる。また、この場合、ボルトに応じた数のナットやワッシャを使用することとなる。トンネル内で親桁どうしの連結をボルトで行う施工時には、１本ずつボルトを締結する作業を行うため、煩雑であった。 A plurality of master girders were provided on the installation portion so as to extend along the vehicle traveling direction, and the ends of the master girders were connected to each other via bolts or connecting plates. For example, when connecting the master girders with bolts, usually, one master girder in a pair of master girders is connected with two bolts. That is, four bolts are used when connecting a pair of master girders to each other. Further, in this case, the number of nuts and washers corresponding to the bolts will be used. At the time of construction in which the main girders are connected with bolts in the tunnel, the work of fastening the bolts one by one is complicated.

以下、本発明の実施形態を図面に基づいて説明する。
本発明のケーブルラックは、トンネル内に敷設され、各種ケーブルを保持する。
図１に示したように、本発明のケーブルラックＸは、長尺状の一本の親桁１０と、当該親桁１０の長手方向に間隔をあけた複数個所に配設してケーブルを保持可能な子桁１１と、を備える。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The cable rack of the present invention is laid in a tunnel and holds various cables.
As shown in FIG. 1, the cable rack X of the present invention is arranged in a long main girder 10 and a plurality of places spaced apart from each other in the longitudinal direction of the main girder 10 to hold cables. It comprises a possible child girder 11.

親桁１０および子桁１１において、材質は何れも金属製とすればよいがこれに限定されるものではなく、樹脂等を使用してもよい。親桁１０は、例えば角柱状の態様とし、親桁１０の上面に短寸の子桁１１を略等間隔で配設した場合について説明するが、このような態様に限定されるものではない。子桁１１はケーブルを保持可能な態様であればその形状は特に限定されるものではない。本実施形態では、子桁１１の両端にケーブルの落下を防止するケーブル止め部１１ａを設けて断面がコ字状を呈する態様とした場合について説明する。本実施形態では、当該子桁１１は、親桁１０にボルト６１で固定する場合について説明するが、この態様に限定されるものではない。当該ボルトは例えば六角ボルトや、皿ボルト等を使用するとよい。 The master girder 10 and the child girder 11 may be made of metal, but the material is not limited to this, and resin or the like may be used. The master girder 10 has, for example, a prismatic aspect, and a case where short child girders 11 are arranged on the upper surface of the master girder 10 at substantially equal intervals will be described, but the present invention is not limited to such an embodiment. The shape of the child girder 11 is not particularly limited as long as it can hold the cable. In the present embodiment, a case will be described in which cable stoppers 11a for preventing the cable from falling are provided at both ends of the child girder 11 so that the cross section has a U-shape. In the present embodiment, the case where the child girder 11 is fixed to the master girder 10 with a bolt 61 will be described, but the present invention is not limited to this embodiment. For the bolt, for example, a hexagon bolt, a countersunk bolt, or the like may be used.

本構成によれば、親桁１０が一本だけで構成してあるため、簡便な構造のケーブルラックＸとすることができる。また、親桁１０が一本だけで構成してあるため、親桁１０どうしを連結する際には、一本の親桁１０だけを連結すればよいため、施工性が向上する。 According to this configuration, since the main girder 10 is composed of only one, the cable rack X having a simple structure can be obtained. Further, since the master girder 10 is composed of only one, when connecting the master girders 10 to each other, only one master girder 10 needs to be connected, so that the workability is improved.

親桁１０は、親桁１０の長手方向に直交する断面視において、子桁１１を載置する上面載置部１０Ａと、当該上面載置部１０Ａの両端から下垂する一対の側方部１０Ｂと、当該側方部１０Ｂの下端部から内側に屈曲し、間隔を開けて互いに対向するように設けられた一対の下フランジ部１０Ｃと、を備えるように構成してある。 The master girder 10 includes an upper surface mounting portion 10A on which the child girder 11 is placed and a pair of side portions 10B hanging from both ends of the upper surface mounting portion 10A in a cross-sectional view orthogonal to the longitudinal direction of the master girder 10. A pair of lower flange portions 10C, which are bent inward from the lower end portion of the side portion 10B and are provided so as to face each other at intervals, are provided.

親桁１０は、トンネル内の車両進行方向に沿って延びるように、ケーブルラックＸを設置する設置部１上に複数設けてある。当該設置部１は、トンネルの側壁にて車両進行方向に沿って略等間隔に複数設けられた支持部材２に亘って、ケーブルラックＸを略水平な状態で設置できるようにしてある。本発明のケーブルラックＸは、設置部１とケーブルラックＸとを固定する固定具２０を備える（図２～４）。 A plurality of master girders 10 are provided on the installation portion 1 in which the cable rack X is installed so as to extend along the vehicle traveling direction in the tunnel. The installation portion 1 allows the cable rack X to be installed in a substantially horizontal state over a plurality of support members 2 provided at substantially equal intervals along the vehicle traveling direction on the side wall of the tunnel. The cable rack X of the present invention includes a fixture 20 for fixing the installation portion 1 and the cable rack X (FIGS. 2 to 4).

固定具２０は、一対の下フランジ部１０Ｃの間をスライド移動可能な固定具板状部材２１と、当該固定具板状部材２１を貫通する固定具ボルト部材２２と、当該固定具ボルト部材２２に螺合する固定具ナット部材２３と、を備える。 The fixture 20 includes a fixture plate-shaped member 21 that can slide and move between the pair of lower flange portions 10C, a fixture bolt member 22 that penetrates the fixture plate-shaped member 21, and the fixture bolt member 22. A fixture nut member 23 to be screwed is provided.

固定具ボルト部材２２は、固定具板状部材２１に形成したボルト穴２１ａを貫通している。固定具板状部材２１において、材質は金属製とすればよいがこれに限定されるものではなく、樹脂等を使用してもよい。本実施形態では、固定具板状部材２１において、設置部１の位置ズレを防止する設置部位置ズレ防止部２１ｂと、親桁１０の位置ズレを防止する親桁位置ズレ防止部２１ｃと、を備えた場合について説明する。設置部位置ズレ防止部２１ｂは固定具板状部材２１に対して下側に折り曲げた状態の一対のフランジ部とし、親桁位置ズレ防止部２１ｃは固定具板状部材２１に対して上側に折り曲げた状態の一対のフランジ部とするのがよいが、このような態様に限定されるものではない。 The fixture bolt member 22 penetrates the bolt hole 21a formed in the fixture plate-shaped member 21. In the fixture plate-shaped member 21, the material may be made of metal, but the material is not limited to this, and resin or the like may be used. In the present embodiment, in the fixture plate-shaped member 21, the installation portion position shift prevention portion 21b for preventing the position shift of the installation portion 1 and the master girder position shift prevention portion 21c for preventing the position shift of the master girder 10 are provided. The case of preparing for it will be described. The installation portion position deviation prevention portion 21b is a pair of flange portions bent downward with respect to the fixture plate-shaped member 21, and the master girder position deviation prevention portion 21c is bent upward with respect to the fixture plate-shaped member 21. It is preferable to use a pair of flange portions in a free state, but the present invention is not limited to this aspect.

固定具２０によってケーブルラックＸと設置部１とを固定する手順は以下の通りである。まず、固定具２０を、親桁１０の端部から一対の下フランジ部１０Ｃの間をスライドさせるようにして親桁１０の内部空間に侵入させる（図２～３）。このとき、固定具板状部材２１の下面の一部が下フランジ部１０Ｃの上面をスライドすることとなる。設置部１に形成してあるＬ字状の溝１ａに固定具ボルト部材２２を係入し、設置部位置ズレ防止部２１ｂである一対のフランジ部によって設置部１を挟持する（図４（ａ））。このとき、親桁位置ズレ防止部２１ｃである一対のフランジ部は、親桁１０の側方部１０Ｂの内側に近接或いは当接した状態となっている（図４（ｂ））。この状態で固定具ボルト部材２２に対して固定具ナット部材２３を螺入させると、固定具板状部材２１の下面の一部と下フランジ部１０Ｃの上面とが密接し、かつ下フランジ部１０Ｃの下面と設置部１の上面とが密接し、さらに固定具ナット部材２３によって設置部１の下面を締め上げることとなる（図４（ｂ））。このようにボルトを締結することで、１つの固定具２０によって設置部１とケーブルラックＸとを固定することができる。 The procedure for fixing the cable rack X and the installation portion 1 with the fixture 20 is as follows. First, the fixture 20 is made to enter the internal space of the master girder 10 by sliding between the end portion of the master girder 10 and the pair of lower flange portions 10C (FIGS. 2 to 3). At this time, a part of the lower surface of the fixture plate-shaped member 21 slides on the upper surface of the lower flange portion 10C. The fixture bolt member 22 is engaged in the L-shaped groove 1a formed in the installation portion 1, and the installation portion 1 is sandwiched by a pair of flange portions which are the installation portion position deviation prevention portions 21b (FIG. 4 (a). )). At this time, the pair of flange portions, which are the master girder position deviation prevention portions 21c, are in a state of being close to or in contact with the inside of the side portion 10B of the master girder 10 (FIG. 4B). When the fixture nut member 23 is screwed into the fixture bolt member 22 in this state, a part of the lower surface of the fixture plate-shaped member 21 and the upper surface of the lower flange portion 10C are in close contact with each other, and the lower flange portion 10C The lower surface of the installation portion 1 and the upper surface of the installation portion 1 are in close contact with each other, and the lower surface of the installation portion 1 is further tightened by the fixture nut member 23 (FIG. 4B). By fastening the bolts in this way, the installation portion 1 and the cable rack X can be fixed by one fixing tool 20.

固定具ボルト部材２２の先端は固定具ナット部材２３が螺合した状態で潰した状態としてもよい。固定具ボルト部材２２の先端を潰すことで当該先端の直径を大きくする等の変形を施すことができ、固定具ナット部材２３がトンネル内の振動等で緩んだとしてもこの変形部分が固定具ナット部材２３の抜け止めとなり、固定具ナット部材２３が固定具ボルト部材２２から抜け落ちるのを未然に防止することができる。 The tip of the fixative bolt member 22 may be crushed with the fixture nut member 23 screwed. By crushing the tip of the fixture bolt member 22, deformation such as increasing the diameter of the tip can be applied, and even if the fixture nut member 23 loosens due to vibration in the tunnel or the like, this deformed portion is the fixture nut. The member 23 is prevented from coming off, and the fixative nut member 23 can be prevented from coming off from the fixture bolt member 22.

本発明のケーブルラックＸは、隣接する親桁１０どうしを接続する接続具３０を備える（図５～７）。当該接続具３０は、一方の親桁１０の端部および他方の親桁１０’の端部を包持する接続具本体３０Ａと、一方の親桁１０の端部および接続具本体３０Ａを貫通し、或いは他方の親桁１０’の端部および接続具本体３０Ａを貫通する少なくとも二本の接続具ボルト部材３３と、当該接続具ボルト部材３３に螺合する少なくとも二つの接続具ナット部材３４と、を備える。 The cable rack X of the present invention includes a connector 30 for connecting adjacent master girders 10 to each other (FIGS. 5 to 7). The connector 30 penetrates the connector body 30A that encloses the end of one master girder 10 and the end of the other master girder 10', and the end of one master girder 10 and the connector body 30A. Or at least two fitting bolt members 33 penetrating the end of the other master girder 10'and the fitting body 30A, and at least two fitting nut members 34 screwed into the fitting bolt member 33. To prepare for.

接続具ボルト部材３３は、一方の親桁１０の端部および接続具本体３０Ａを貫通する少なくとも一本の接続具ボルト部材３３と、他方の親桁１０’の端部および接続具本体３０Ａを貫通する少なくとも一本の接続具ボルト部材３３とを設けるようにすればよい。そのため、接続具ボルト部材３３の数は二本以上であればよい。接続具ナット部材３４の数は接続具ボルト部材３３の数に合わせればよい。 The connector bolt member 33 penetrates at least one connector bolt member 33 that penetrates the end of one master girder 10 and the connector body 30A, and the end of the other master girder 10'and the connector body 30A. At least one connector bolt member 33 may be provided. Therefore, the number of connector bolt members 33 may be two or more. The number of fitting nut members 34 may be adjusted to match the number of fitting bolt members 33.

接続具本体３０Ａは、親桁１０の上面載置部１０Ａと対面する接続具本体上面部３０ａと、親桁１０の側方部１０Ｂと対面する一対の接続具本体側面部３０ｂと、親桁１０の下フランジ部１０Ｃと対面する一対の接続具本体下フランジ部３０ｃと、を備えるように構成してある。このように接続具本体３０Ａは、親桁１０を包むように親桁１０を保持して隣接する親桁どうしを接続することができる態様となっている。 The connector main body 30A includes a connector main body upper surface portion 30a facing the upper surface mounting portion 10A of the master girder 10, a pair of connector main body side surface portions 30b facing the side portion 10B of the master girder 10, and a master girder 10. It is configured to include a pair of connecting tool main body lower flange portions 30c facing the lower flange portion 10C. In this way, the connector main body 30A is in a mode in which the master girder 10 can be held so as to wrap the master girder 10 and the adjacent master girders can be connected to each other.

接続具本体３０Ａは金属製とすればよいがこれに限定されるものではなく、樹脂等を使用してもよい。接続具ボルト部材３３は、親桁１０および接続具本体３０Ａのそれぞれに形成したボルト穴１０α，３０αを貫通している。本実施形態では、２本の接続具ボルト部材３３を使用する態様について説明するが、この態様に限定されるものではない。 The connector body 30A may be made of metal, but the present invention is not limited to this, and resin or the like may be used.

Lighting device connecting members 50A are attached to both ends of the lighting device 50. The illuminating device connecting member 50A includes a connecting plate-shaped portion 50a that comes into surface contact with the illuminating device fixture 40. The connection plate-shaped portion 50a can be provided so as to face the end portion of the lighting device 50, but is not limited to such an embodiment. The locking plate portion 41 can be penetrated into the internal space of the main girder 10 from between the pair of lower flange portions 10C, and can be engaged by the pair of lower flange portions 10C by changing to a posture different from that at the time of the penetration. The shape is not particularly limited as long as it can be stopped. The locking plate portion 41 of the present embodiment has a rectangular plate shape, the length of the locking plate portion 41 is longer than the dimension between the pair of lower flange portions 10C, and the short dimension of the locking plate portion 41 is A case where the dimension of the locking plate portion 41 is set to be shorter than the dimension between the pair of lower flange portions 10C will be described. When the locking plate portion 41 is configured in this way, when the lighting device fixture 40 is changed to a posture different from that at the time of the intrusion, both ends of the locking plate portion 41 on the long side are paired with lower flange portions. Since it can be locked to the 10C, the locking plate portion 41 can be locked by the pair of lower flange portions 10C.
