【発明の詳細な説明】
本発明は、接続部を有する複数本のケーブルをトラフ内
に布設する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for laying a plurality of cables with connections in a trough.
一般に、ケーブルの接続部は導体の圧縮時に伸びが生ず
るのでこのような伸びはケーブルのオフセットを取って
吸収しなげればならなＬ・。Generally, cable connections will stretch when the conductor is compressed, so this stretch must be absorbed by offseting the cable.
このため、従来ケーブルをトラフ内に布設する場合その
接続部の前後にオフセット部を形成してＬ・た。For this reason, conventionally, when a cable is laid in a trough, offset portions are formed before and after the connection portion.
しかし、接続部とその前後のオフセット部を含む全長は
通常６０ｍ程度と著しく長く、オフセットを取る作業が
面倒で作業性が低℃・欠点があった。However, the total length including the connecting portion and the offset portions before and after the connecting portion is usually extremely long, about 60 m, and the work to remove the offset is troublesome and the workability is low.
本発明の目的は、短（・長さの中で接続部の伸びを吸収
しつつ接続部を含むケーブル全体をトラフ内に布設する
ことができる方法を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a method in which the entire cable, including the connection part, can be laid in a trough while absorbing the elongation of the connection part within a short length.
本発明の実施例を図面を参照してのべると、第１図は本
発明に係る方法を概略的に示す。Embodiments of the invention will now be described with reference to the drawings, in which FIG. 1 schematically shows a method according to the invention.
本発明の方法では複数本のケーブルＡ、Ｂ、Ｃを図示し

ーブルはその引込時に図示のようにその接続部ａ、ｂ、
ｃが縦方向にずれるようにし、且つこの接続部を含む部
分で転移するように撚られて引込まれる。In the method of the present invention, a plurality of cables A, B, and C are sequentially drawn into a U trough (not shown) and laid.
c is shifted in the longitudinal direction, and is twisted and drawn in such a way that it transfers at the part that includes this connection.
このようにすると、各ケーブルは第２図Ａ乃至りに示す
ようにその断面位置が順次時計方向に回転するように転
移する。In this way, the cross-sectional positions of each cable are sequentially rotated clockwise as shown in FIGS. 2A to 2A.
このため、各ケーブルはそれぞれ短い距離の中で相応す
る接続部の伸びを吸収するようにスネーク状にオフセッ
トが取られる。For this purpose, each cable is offset in a snake-like manner so as to accommodate the elongation of the corresponding connection within a short distance.

った。In one embodiment of the present invention, the length tl of the transition portion of the cable is 2284 mm, the length t2 of the straight portion including the connection portion is 4600 mm, and the total length L is 22936 mm.
8 (approximately 23 m), it was possible to remove the offset of all cables A, B, and C, which was significantly shorter than the conventional 60 m.
本発明によれば、上記のように、トラフ内に布設される
複数本のケーブルを撚合せてスネーク状のオフセットを
取りながら布設するのでオフセット部分は短かくてよ（
・から作業性がよく、且つ接続部は順次縦方向にずらせ
であるのでトラフ内のケーブル収納断面積は小さくてよ
く接続部を含めてトラフ内に収納することカーできる実
益がある。According to the present invention, as described above, a plurality of cables laid in a trough are twisted together and laid while taking a snake-shaped offset, so that the offset portion is short (
- Workability is good, and since the connecting parts are sequentially shifted in the vertical direction, the cross-sectional area for storing cables in the trough is small, and it is practical to store the cables including the connecting parts in the trough.
