本発明によれば、施工作業が迅速に行えると共に、施工作業コストを安価にしうるケーブルトラフの施工構造を提供出来るとの効果を奏する。
According to the present invention, it is possible to provide a construction structure of a cable trough that can perform construction work quickly and can reduce construction work costs.

以下本発明を図に示す実施例に基づいて説明する。
図１に本発明によるケーブルトラフの施工構造を示す。 Hereinafter, the present invention will be described based on embodiments shown in the drawings.
FIG. 1 shows a construction structure of a cable trough according to the present invention.

図１において、符号１は高架橋型の鉄道用線路を示し、当該高架型鉄道用線路１の幅方向両端部には各種複数のケーブル２・・・が収納されたケーブルトラフ３が前記高架型鉄道用線路１の長手方向に向かって敷設される。 In FIG. 1, reference numeral 1 denotes a viaduct type railway line, and a cable trough 3 in which various cables 2... Are accommodated at both ends in the width direction of the elevated railway line 1 is the elevated railway. It is laid in the longitudinal direction of the service line 1.

なお、本発明において、高架型の鉄道線路に限定されるものではなく、一般道路などの交通路でも構わない。 In the present invention, the present invention is not limited to an elevated railway track, and may be a traffic road such as a general road.

符号４は鉄道用線路１の高欄であり、該鉄道用線路１の長手方向に向かって側壁状に設置されている。 Reference numeral 4 denotes a rail of the railroad track 1, which is installed in a side wall shape in the longitudinal direction of the railroad track 1.

該高欄４は防音壁、遮音壁の機能をも果たすものであり、いわゆるＣＦＲＰ製、すなわち炭素繊維強化プラスチック製で形成されることが近年数多く見られる。 当該炭素繊維強化プラスチック製で形成される近年の高欄４は、従来製品の高欄４と比較すると、従来品の５分の１乃至１０分の１の重量にすることが出来、超軽量化をはかることができる。また、施工作業性に優れており、高欄施工の工期を大幅に短縮出来る。 The balustrade 4 also functions as a sound barrier and a sound barrier, and in recent years it is often seen that it is made of so-called CFRP, that is, made of carbon fiber reinforced plastic. The recent rail 4 made of the carbon fiber reinforced plastic can be made one-fifth to one-tenth the weight of the conventional product compared to the conventional product 4 and can be super lightweight. be able to. Moreover, it is excellent in workability and can significantly shorten the work period of the railing work.

さらに、防音特性、謝恩特性にも優れ、前記の超軽量化の効果も相まって、軽量化と防音性、遮音性を両立できるものとされている。 Furthermore, it is excellent in soundproofing characteristics and gratitude characteristics, and combined with the effect of ultra-lightening, it is possible to achieve both weight reduction, soundproofing and sound insulation.

また、従来製品に比して、高強度、高剛性であり、しかも腐食せず、小片剥落がないため耐久性、安全性がきわめて高いものとなっている。 In addition, compared with conventional products, it has high strength and high rigidity, does not corrode, and does not peel off small pieces, so it has extremely high durability and safety.

一般に、本発明による高欄４は、図から理解されるように、発泡体などにより構成された所定の厚みを有する平板状のコア材５と、該コア材５を被覆するスキン層６とにより構成されている。そして、前記スキン層６が炭素繊維、合成樹脂などの樹脂で構成される。 In general, the balustrade 4 according to the present invention is constituted by a flat core material 5 having a predetermined thickness made of foam or the like, and a skin layer 6 covering the core material 5 as understood from the drawing. Has been. The skin layer 6 is made of a resin such as carbon fiber or synthetic resin.

ここで、前記高欄４は、線路幅方向両端部から、あるいは一方側の端部から上方に向かい立ち上がって形成され、かつ線路の長手方向に向かって長尺に連続して設けられている。 Here, the rail 4 is formed so as to rise upward from both ends in the line width direction or from an end on one side, and is provided continuously in a long direction in the longitudinal direction of the line.

しかして、本発明では、ケーブルトラフ３の施工に際し、前記高欄４などをケーブルトラフ３の一方側の側壁として利用するものとした。 Therefore, in the present invention, when the cable trough 3 is constructed, the rail 4 or the like is used as a side wall on one side of the cable trough 3.

次いで、符号７は、底壁部８及び該底壁部８の幅方向一端から略垂直に立ち上る他方側側壁部９とによって断面略Ｌ字状をなして形成されたケーブルトラフ本体を示す。 Next, reference numeral 7 denotes a cable trough main body formed in a substantially L-shaped cross section by the bottom wall portion 8 and the other side wall portion 9 rising substantially vertically from one end in the width direction of the bottom wall portion 8.

ここで、該ケーブルトラフ本体７は、あらかじめ工場でプレキャストコンクリート製品として形成される。このように、ケーブルトラフ３を形成するために大部分の時間が費やされるケーブルトラフ本体７の部分をあらかじめプレキャストコンクリート製品としておくと、このプレキャスト製品化したケーブルトラフ本体７・・・を製造して製造工場に大量にストックしておき、その後必要に応じて大量に施工現場（高架型鉄道用線路１内）へ運搬できる。 Here, the cable trough body 7 is formed in advance as a precast concrete product in a factory. As described above, when the portion of the cable trough body 7 that takes most of the time to form the cable trough 3 is precast concrete product, the cable trough body 7. A large amount can be stocked in the manufacturing factory, and then transported to the construction site (inside the elevated railway line 1) in large quantities as necessary.

施工現場では、これらケーブルトラフ本体７・・・を線路長手方向に順次接続してケーブルトラフ３を敷設するのみですみ、大幅に施工時間が短縮でき、施工コストも安価にすることが出来る。しかも従来に比して大幅に品質も向上させることが出来るとのメリットがある。 At the construction site, it is only necessary to connect the cable trough bodies 7... Sequentially in the longitudinal direction of the track and to lay the cable trough 3, so that the construction time can be greatly shortened and the construction cost can be reduced. Moreover, there is a merit that the quality can be greatly improved as compared with the prior art.

ここで、前記ケーブルトラフ本体７の底壁部８には、道路あるいは線路の路面上に打設されるモルタル１５と一体化させる連結アンカー１６の施工用穴１０が設けられていると共に、長手方向略中央には吊り上げ運搬用の吊り上げナット穴１１が設けられている。 Here, the bottom wall portion 8 of the cable trough body 7 is provided with a construction hole 10 for a connecting anchor 16 that is integrated with a mortar 15 placed on the road surface of a road or a track, and in the longitudinal direction. A lifting nut hole 11 for lifting and transporting is provided substantially at the center.

この連結アンカー１６の施工用穴１０及び吊り上げ運搬用の吊り上げナット穴１１の形成個数については何ら制限されるものではなく、それぞれ２個以上の複数個設けても構わないものである。
図７に示す具体例では、連結アンカー１６の施工用穴１０は底壁部８の長手方向端部側に１個ずつ、また吊り上げナット穴１１は１個の合計３個形成してある。 The numbers of the construction holes 10 and the lifting nut holes 11 for lifting and transporting the connecting anchor 16 are not limited at all, and two or more of them may be provided.
In the specific example shown in FIG. 7, the construction holes 10 of the connection anchor 16 are formed one by one on the longitudinal direction end side of the bottom wall portion 8, and the lifting nut holes 11 are formed in total of three.

さらに、ケーブルトラフ本体７の長手方向両端面の底壁部８及び他方側側壁部９との境目部には水抜き穴形成用切り欠き１２が半円状に切り欠かれて設けられおり、前記ケーブルトラフ本体７がその長手方向に接続されたとき、略円状の水抜き穴が形成されることになる。 Further, a drain hole forming notch 12 is provided in a semicircular shape at the boundary between the bottom wall portion 8 and the other side wall portion 9 on both end surfaces in the longitudinal direction of the cable trough body 7, When the cable trough body 7 is connected in the longitudinal direction, a substantially circular drain hole is formed.

ところで、前記ケーブルトラフ本体７における他方側側壁部９の上端内側には略Ｌ字状に凹んで形成されたトラフ蓋載置用段つき部１３が設けられている。 Incidentally, a trough lid mounting stepped portion 13 formed in a substantially L-shape is provided on the inner side of the upper end of the other side wall portion 9 in the cable trough main body 7.

また、ケーブルトラフ本体７の他方側側壁部９と対向する、例えば線路などの高欄４あるいは側壁の一方側側壁部内側においても略Ｌ字状に凹んで形成されたトラフ蓋載置用段つき部１３が設けられる。 Also, a stepped portion for placing a trough lid facing the other side wall portion 9 of the cable trough body 7 and formed in a substantially L-shape, for example, inside the rail 4 or the inner side wall portion of the side wall. 13 is provided.

例えば、線路などの高欄４あるいは側壁の内側において、略Ｌ字状に凹んで形成されたトラフ蓋載置用段つき部１３があらかじめ設けられていることもあるが、このようなトラフ蓋載置用段つき部１３があらかじめ設けられていないときは、施工現場において新たに高欄４や側壁の内側に前記トラフ蓋載置用段つき部１３を形成する必要がある。しかし、この形成作業は決して困難なものではなく、例えば長尺の角棒状部材を線路などの高欄４あるいは側壁の内側に水平方向へ延出させて取り付ければよいのである。 For example, there is a case where a trough lid mounting stepped portion 13 formed in a substantially L-shape is provided in advance in the rail 4 or the inside of the side wall. When the stepped portion 13 is not provided in advance, it is necessary to newly form the stepped portion 13 for placing the trough lid on the inside of the rail 4 or the side wall at the construction site. However, this forming operation is never difficult. For example, a long square bar-like member may be attached to the rail 4 or the inside of the side wall so as to extend horizontally.

このような取り付け作業により、固定した角棒状部材の上面と、線路などの高欄４あるいは側壁の内側面とによりトラフ蓋載置用段つき部１３が容易に形成できることとなる。 By such an attaching operation, the trough lid mounting stepped portion 13 can be easily formed by the upper surface of the fixed rectangular bar-like member and the rail 4 or the inner side surface of the side wall.

そして、これら略Ｌ字状に凹んで形成されたトラフ蓋載置段つき部１３，１３間にケーブルトラフ蓋１４が載置される。 Then, the cable trough lid 14 is placed between the trough lid placing stepped portions 13 and 13 formed to be recessed in a substantially L shape.

次に、本発明によるケーブルトラフ３の施工につき説明する。 Next, the construction of the cable trough 3 according to the present invention will be described.

まず鉄道の線路あるいは高速道路あるいはトンネルの路面幅方向端部に図に示すようにモルタル１５を打設する。ついでケーブルトラフ本体７を前記鉄道の線路あるいは高速道路あるいはトンネルの路面幅方向端部に敷設する。 First, a mortar 15 is placed as shown in the figure at the end in the width direction of a railway track, expressway or tunnel. Next, the cable trough main body 7 is laid on the end of the railroad track, the expressway or the tunnel in the road surface width direction.

ここで、ケーブルトラフ本体７の吊り上げ運搬作業及び敷設作業は、前記した吊り上げナット穴１１が利用される。 Here, the lifting nut hole 11 is used for lifting and carrying work and laying work of the cable trough body 7.

すなわち、ケーブルトラフ本体７を構成する他方側側壁部９の長手方向両上端部を所定の把持部材で把持すると共に、前記の吊り上げナット穴１１にボルト状吊り上げ棒を螺合し、いわゆる３点吊りの状態にして吊り上げ、かつ運搬し、所定位置に載置するのである。 That is, both upper ends in the longitudinal direction of the other side wall portion 9 constituting the cable trough body 7 are gripped by a predetermined gripping member, and a bolt-shaped lifting rod is screwed into the lifting nut hole 11 so as to suspend the so-called three-point suspension. In this state, it is lifted, transported, and placed at a predetermined position.

ところで、ケーブルトラフ本体７の敷設箇所には、あらかじめ棒状の連結アンカー１６、１６が突設されて仮設されている。よって、吊り上げられているケーブルトラフ本体７の前記連結アンカー１６の施工用穴１０、１０に前記突設された連結アンカー１６が遊嵌するように降下させれば、簡単に位置決めできて所定箇所にケーブルトラフ本体７を敷設できるものとなる。 By the way, rod-like connecting anchors 16 and 16 are provided in a projecting manner in advance at the laying position of the cable trough body 7. Therefore, if the projecting connection anchor 16 is lowered so that the projecting connection anchor 16 is loosely fitted in the construction holes 10 and 10 of the connection anchor 16 of the cable trough body 7 that is being lifted, the positioning can be easily performed. The cable trough body 7 can be laid.

これによりケーブルトラフ本体７の迅速、確実な敷設が確保できるとの効果が得られる。 Thereby, the effect that quick and reliable laying of the cable trough main body 7 is securable is acquired.

しかして、前記ケーブルトラフ本体７の敷設により、鉄道の線路あるいは高速道路あるいはトンネルの路面幅方向端部には、高欄４や側壁の内側側壁と略Ｌ字状をなすケーブルトラフ本体７とにより断面凹状をなすケーブルトラフ３の収納庫が形成できる。 Thus, by laying the cable trough main body 7, the cross section of the railroad track or the highway or tunnel in the road surface width direction is cut by the rail trough 4 and the cable trough main body 7 having an approximately L shape with the inner side wall of the side wall. A storage for the concave cable trough 3 can be formed.

なお、連結アンカー１６の施工用穴１０からは例えば固定用モルタル１５を打設して、ケーブルトラフ本体７を前記モルタル１５に固定するものとする。 Note that, for example, a fixing mortar 15 is driven from the construction hole 10 of the connection anchor 16 to fix the cable trough body 7 to the mortar 15.

かかる敷設作業を、路面の長手方向に向かってケーブルトラフ本体７を繋げながら行う。 Such laying work is performed while connecting the cable trough body 7 in the longitudinal direction of the road surface.

そして、最終的には、ケーブルトラフ３内に各種のケーブル２・・・を収納した後、対向するトラフ蓋載置用段つき部１３，１３間にケーブルトラフ蓋１４を載置してケーブルトラフの施工終了となる。
Finally, after the various cables 2... Are stored in the cable trough 3, the cable trough lid 14 is placed between the facing trough lid mounting stepped portions 13, 13. This is the end of construction.
