技術分野  Technical field
[0001] 本発明は、通信ケーブルや電力ケーブル等のケーブル類の敷設に使用されるケ 一ブルトラフに関する。  The present invention relates to a cable trough used for laying cables such as a communication cable and a power cable.
背景技術  Background art
[0002] 鉄道の線路脇に、この線路に沿ってケーブル類を敷設する場合、一般的に、ケー ブル類は導管内に収容されており、そして、この種の導管は多数のケーブルトラフを 一列に並べて構築されて 、る。  [0002] When laying cables alongside a railway track, the cables are generally housed in conduits, and such conduits have a large number of cable troughs arranged in a line. It is built side by side.
[0003] 個々のケーブルトラフは、両端及び上面がそれぞれ開口したトラフボディと、このトラ フボディの上面開口を塞ぐリツドとを含む。通常、トラフボディは 400— 500mm程度 の長さを有し、コンクリートから形成されている。 [0003] Each cable trough includes a trough body having both ends and an upper surface opened, and a lid for closing an upper surface opening of the trough body. Usually, the trough body has a length of about 400-500 mm and is made of concrete.
[0004] し力しながら、コンクリート製のトラフボディは重いため、ケーブル類の敷設作業は容 易ではない。このため、例えば、特開 2000-55240号公報に開示されたトラフボディは プラスチックから形成されて 、る。 [0004] However, since the trough body made of concrete is heavy, it is not easy to lay cables. For this reason, for example, the trough body disclosed in JP-A-2000-55240 is formed of plastic.
[0005] プラスチック製のトラフボディは、敷設作業を容易にする観点力もみてコンクリート製 のトラフボディに比べて優れるが、敷設後、ケーブル類の保守の観点からみたときに はコンクリート製のトラフボディに比べて劣る。 [0005] The plastic trough body is superior to the concrete trough body in view of the power of facilitating the laying work. Inferior compared.
[0006] 即ち、トラフボディは、略 U字形の横断面形状を有するため、安定性に乏しぐしか も、のため、プラスチック製のトラフボディが一部地中に埋めて配置される力、又は、 地表上に直接に配置されている状況にて、トラフボディの側面に外力が加わると、トラ フボディは容易に傾き易い。このようなトラフボディの傾きは、その内部のケーブル類 に捻れを引き起こし、ケーブル類を損傷させる虞がある。  [0006] That is, the trough body has a substantially U-shaped cross-sectional shape, and therefore has little stability. Therefore, a force at which a plastic trough body is partially embedded in the ground, or When the trough body is placed directly on the ground surface and an external force is applied to the side surface of the trough body, the trough body is easily tilted. Such inclination of the trough body may cause twisting of the cables inside the trough body, and may damage the cables.
発明の開示  Disclosure of the invention
[0007] 本発明の目的は、トラフボディが一部地中に埋めて配置される力 又は、地表上に 直接配置される否かに拘わらず、トラフボディを安定して配置することができるケープ ルトラフを提供することにある。 [0008] 上記の目的を達成するため、本発明のケーブルトラフは、両端及び上面にてそれ ぞれ開口し、底壁及び左右の側壁を有したトラフボディと、このトラフボディの上面開 口を閉塞するリツドとを備え、トラフボディは、少なくとも一方の側壁の外面に備えられ 、トラフボディが設置状態を安定させるためのスタビライザを更に含む。 [0007] An object of the present invention is to provide a cape capable of stably arranging a trough body irrespective of whether the trough body is partially buried in the ground or whether the trough body is directly arranged on the ground surface. To provide rut trough. [0008] In order to achieve the above object, a cable trough according to the present invention includes a trough body having a bottom wall and left and right side walls which are opened at both ends and an upper surface, respectively, and a top opening of the trough body. The trough body further includes a stabilizer provided on an outer surface of at least one of the side walls, for stabilizing an installation state of the trough body.
[0009] トラフボディはスタビライザとともにプラスチック力も形成されて!、るのが好ま 、。  [0009] The trough body is formed with plastic power together with the stabilizer! , Prefer to run.
[0010] 具体的には、スタビライザ、側壁から突出し、且つ、トラフボディの軸線方向に延び る少なくとも 1つのフィンを含むことができる。トラフボディが設置されたとき、フィンは 地中に埋められる。トラフボディが側方力も外力を受け、この外力により傾こうとすると き、フィンは、トラフボディの傾動に対する抵抗となり、トラフボディの傾きを阻止する。  [0010] Specifically, the stabilizer may include at least one fin projecting from the side wall and extending in the axial direction of the trough body. When the trough body is installed, the fins are buried underground. When the trough body also receives external force and tries to lean by the external force, the fins provide resistance to the tilting of the trough body and prevent the trough body from tilting.
[0011] 上述したフィンは、トラフボディの一端力も他端に亘つて延びて 、てもよ 、し、また、 複数にフィン要素に分離されて 、てもよ 、。  [0011] The above-described fin may extend at one end of the trough body over the other end, or may be separated into a plurality of fin elements.
[0012] フィンに代えて、スタビライザは側壁力 突出する複数のロッド即ち杭や、側壁の外 面に形成した少なくとも 1個の窪みであってもよい。これら杭及び窪みが地中に埋め られた状態で、トラフボディが設置されたとき、これら杭及び窪みもまた前述のフィンと 同様な機能を発揮する。  [0012] Instead of the fin, the stabilizer may be a plurality of rods or piles protruding from the side wall, or at least one depression formed on the outer surface of the side wall. When the trough body is installed with these piles and depressions buried in the ground, these piles and depressions also perform the same functions as the fins described above.
[0013] フィンは、底壁に対して垂直な垂直部分を有することができる。この場合、トラフボデ ィにその軸線方向力 の外力が加わり、この外力によりトラフボディが軸線方向に移 動しょうとしても、この移動に対してフィンの垂直部分が抵抗となる。従って、トラフボ ディは軸線方向にも容易に移動することがな 、。  [0013] The fin may have a vertical portion perpendicular to the bottom wall. In this case, an external force of the axial force is applied to the trough body, and even if the trough body attempts to move in the axial direction due to the external force, the vertical portion of the fin resists the movement. Therefore, the trough body cannot easily move in the axial direction.
[0014] 本発明のケーブルトラフは、スタビライザと協働してトラフボディを地表上に固定す るための少なくとも 1つのアンカユニットを更に含むことができる。この場合、アンカュ ニットは、スタビライザ、即ち、フィン、杭又は窪みを上方力も押え付ける締結プレート 、即ち、タイプレートを有する。  [0014] The cable trough of the present invention may further include at least one anchor unit for fixing the trough body on the ground surface in cooperation with the stabilizer. In this case, the anchor unit has a stabilizer, ie, a fastening plate, ie, a tie plate, which also holds down the upward force on the fins, piles or depressions.
[0015] 従って、アンカユニットを使用してトラフボディが地表上に設置されたとき、アンカュ ニットのタイプレートはトラフボディのスタビライザを上方力 押さえ付けることができる 。それ故、トラフボディに側方からの外力が加わっても、トラフボディが傾くことはない  [0015] Therefore, when the trough body is installed on the ground surface using the anchor unit, the tie plate of the anchor unit can hold down the stabilizer of the trough body by an upward force. Therefore, even if external force is applied to the trough body from the side, the trough body does not tilt
[0016] 上述したように本発明のトラフボディは地中に埋められた状態で設置される力 又 は、アンカユニットを使用して地表上に設置されても、容易に傾くことがない。この結 果、トラフボディ内に収容されたケーブル類に捻れが発生することもないので、ケー ブル類の損傷は長期に亘つて防止される。 [0016] As described above, the trough body of the present invention is a force installed in a state buried in the ground. Is not easily tilted when placed on the ground using an anchor unit. As a result, the cables housed in the trough body are not twisted, so that the cables are prevented from being damaged for a long time.

[0018] 図 1に示された第 1実施例のケーブルトラフ 2は多数用意され。これらケーブルトラフ 2は一列に配置されて、通信ケーブル又はパワーケーブル等のケーブル類の敷設に 使用される。 [0018] A large number of cable troughs 2 of the first embodiment shown in Fig. 1 are prepared. These cable troughs 2 are arranged in a row and used for laying cables such as communication cables or power cables.
[0019] ケーブルトラフ 2はトラフボディ 4及びリツド 6を含み、これらトラフボディ 4及びリツド 6 は共にプラスチック、好ましくはリサイクルプラスチックカゝら形成されている。トラフボデ ィ 4は略 U字形の横断面形状をなし、底壁 8及び左右の側壁 10を有する。従って、ト ラフボディ 4は両端及び上面にてそれぞれ開口し、リツド 6はトラフボディ 4の上面開口 を開閉可能に閉塞する。トラフボディ 4がリツド 6により閉じられたとき、ケーブルトラフ 2 はケーブル類を収納可能なトンネル状に形成される。  [0019] The cable trough 2 includes a trough body 4 and a rim 6, and the trough body 4 and the rim 6 are both formed of plastic, preferably a recycled plastic car. The trough body 4 has a substantially U-shaped cross section, and has a bottom wall 8 and left and right side walls 10. Accordingly, the trough body 4 opens at both ends and the upper surface, respectively, and the lid 6 closes the upper opening of the trough body 4 so as to be openable and closable. When the trough body 4 is closed by the rim 6, the cable trough 2 is formed in a tunnel shape capable of storing cables.
[0020] 第 1実施例の場合、各側壁 10はその下部にスタビライザとしてのフィン 12をそれぞ れ有する。これらフィン 12は対応する側壁 10に一体に形成され、側壁 10の外面から 水平に突出し、底壁 8の延長部分を形成する。より詳しくは、フィン 12は側壁 10に対 して直交するプレートからなり、トラフボディ 4の軸線に沿い、トラフボディ 4の両端間 に亘つて延びている。 [0021] 図 1のケーブルトラフ 2の場合、トラフボディ 4はその下部、即ち、左右のフィン 12が 地中に埋められた状態で配置されている。なお、図 1中の参照符号 S は地表を表し In the case of the first embodiment, each side wall 10 has a fin 12 as a stabilizer at its lower part. These fins 12 are formed integrally with the corresponding side wall 10 and project horizontally from the outer surface of the side wall 10 to form an extension of the bottom wall 8. More specifically, the fin 12 is formed of a plate orthogonal to the side wall 10 and extends along the axis of the trough body 4 and between both ends of the trough body 4. In the case of the cable trough 2 in FIG. 1, the trough body 4 is disposed at a lower portion thereof, that is, in a state where the left and right fins 12 are buried in the ground. The reference symbol S in Fig. 1 represents the ground surface.

As a result, the cables are not twisted in the trough body 4, and the damage of the cables due to this twist is also reliably prevented.
