Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a cable along a cable laying route in a wall or ceiling structure of a structure such as a ship or a building, and a cable support used in the method. .

[0002]

2. Description of the Related Art Conventionally, various types of cable laying methods and cable supports of this kind have been proposed. For example, Japanese Unexamined Patent Publication (Kokai) No. 59-129517 discloses an electric circuit leg at a predetermined mounting position on a structure. A circuit construction method is disclosed, which comprises mounting a pre-assembled circuit hanger on a mounted circuit path leg and fixing the circuit hanger with a fastener such as a bolt.

Japanese Patent Laid-Open Publication No. Sho 60-141111 discloses a stud bolt which is welded to a structure and a flat bar which is mounted on the stud bolt with a bolt. Discloses a stud-welded feeder that is shaped so as not to damage the wires.

Japanese Utility Model Publication No. 5-21926 discloses a hull in which a stud pin is welded to a rod-shaped or flat bar-shaped body for supporting an electric wire at a substantially central portion thereof, and a stud welding projection is provided at a base of the stud pin. A mounting hardware is disclosed.

[0005]

As described above, both the conventional cable laying method and the conventional cable support device attach the support leg of the electric circuit to a predetermined mounting position of the structure by a stud welding method. The structure of the cable support body itself that supports it is complicated, the manufacturing cost is high, and the bolts etc. are used to attach the cable support body to the support legs of the electric circuit, so the assembly work is troublesome. There was a problem.

[0006] In order to solve such a problem, a single bar is bent into a T shape and both free ends are bent into a loop.
A U-shaped cable support has been proposed (see EP 0 728 975). This has the advantage that it can be easily manufactured and that the installation is not troublesome.

However, in actual cable laying, it is common to design variously according to the requirements such as the number of cables and the outer diameter and the laying scale. Therefore, it is necessary to prepare cable supports of various sizes in advance so as to be able to meet such requirements. In the single T-shaped cable support as described above, the support leg may need to be short and may need to be long depending on the situation at the installation site. Therefore, in order to meet such a demand, it is necessary to prepare various support legs having different lengths. Therefore, even though such a simple T-shaped cable support has a simple structure and advantages in terms of manufacturing cost and ease of installation, from the viewpoint of actual work at the cable installation site, cables of various sizes are used. It is necessary to prepare a support tool for each size, which is rather expensive. In addition, since it is bulky, it becomes obstructive especially at a site where the working environment is narrow, and the workability is reduced.

Accordingly, the present invention solves such problems associated with the conventional cable laying, can greatly improve the cable laying work efficiency, and can easily cope with the situation of the cable laying site on site.
