Abstract

PROBLEM TO BE SOLVED: To achieve the simplification of cable laying work and cable support and fixing work and the improvement of work efficiency, even in an outfitting method (preceding outfitting) which is performed when a hull block is on the ground or in a conventional outfitting in the condition with the hull block being set up, when a worker lays a cable for power, communication, etc., to be wired between each electrical apparatus and the other cable equipped mainly within a vessel. SOLUTION: This is a cable way for laying a cable used for the wiring construction of a vessel. In this cable way for laying a cable, slave beams each of which is bent into an S shape tiered in its cross section and in each of which at least two or more pieces of slots vertical to the cross section are opened in top and bottom planes, are arranged at fixed intervals so that the top and bottom planes are horizontal to a master beam. Hereby, cables can be laid and bound firmly on both sides of the topside and the downside of the cable way. Hereby, no matter how the cable way may face the top or bottom, the temporary fixing, etc., at cable laying can be omitted. Moreover, a band can slide through the cut at the flank and bind the cables firmly, in the work of binding the cables firmly with the band by opening one end of a slot in each slave beam of the cable way.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used for supporting and fixing electric wires for electric power, communication and other electric wires to be wired between electric devices installed in a ship. It is about electric circuits.

[0002]

2. Description of the Related Art Conventionally, electric wires in ships are generally laid on the ceiling, and the electric wires are laid manually on this electric line. It was a work that always looked up, and I felt quite tired in my upper arms and neck. Moreover, in order to perform work while raising the line of sight to the height of the electric path, a stepladder or step was required, which meant that the work space was limited and work efficiency was extremely poor.

The above work places a heavy burden on the worker, and the work efficiency is significantly deteriorated. Therefore,
In order to solve these problems, in recent years, with the ceiling surface facing down when the ship was in the block state, the ship block was placed on the ground, and the electric line originally placed on the ceiling was facing downward. An outfitting method (advanced outfitting) for mounting and wiring work is adopted.

The outfitting method (advanced outfitting) is performed on the hull block placed on the ground, and in some cases, the work can be done inside the factory, so that the working environment is good and the efficiency is appropriately increased. It was done.

As a conventional electric wire laying path, the one shown in FIG. 11 is generally used. In the perspective view of FIG. 11, 31 is a parent girder, and 32 is a child girder installed so that the parent girders are orthogonal to each other with a fixed interval. FIG. 12 is a front view, a plan view and a side view of the slave girder. This child girder 32 has a long hole 3 for securing the electric wire.
3 is vacant, and by passing the band through it,
Secure the electric wire to the electric circuit and fix it. The child girders are welded at regular intervals so that the surface of the girders having the elongated holes is parallel to the conduit pipe of the parent girder.

FIG. 13 is a perspective view of the conventional electric wire laying electric path when the electric wire is laid in an actually used state. The electric wire laying electric line is fixed to the ceiling surface of the hull so that it can be hung by the electric line attachment feet 43. An electric wire 44 is provided only above the slave girder 42.
Is laid, and is fastened to the electric path by a fastening band 45. FIG. 14 is a cross-sectional view of the electric circuit mounting foot portion.
At the time of the previous outfitting, it is attached in a state in which FIG. 13 is upside down.

When attempting to perform the above-described outfitting with this conventional electric wire laying electric path, since the horizontal surface of the slave girder having the long hole for fixing the electric wire is only one of the upper sides, the electric wire is provided only above the electric path. Only can be laid. Therefore, in the construction when the hull block on the ground is upside down, the horizontal surface of the child girder with the long holes for wire staking is on the lower side because the electric line is installed upside down. Therefore, it is necessary to lay an electric wire on the lower side of the upside-down electric circuit (upward when the hull block is assembled). Therefore, it was necessary to first temporarily fix the electric wire to the electric wire with a wire or the like, and then to tie the electric wire with a band, which was a double labor. In addition, since the electric wire hangs down due to its own weight, it is necessary to take measures such as increasing the number of child girders and increasing the number of lashing points.

After that, when the electric wire is laid after the hull block is normally rotated and assembled, the electric wire that has been pre-rigged has already been laid on the upper side of the electric path, and when the electric wire has been laid later, the electric wire has been pre-rigged. The tie-down band of the electric circuit was sometimes caught and hindered the work. In addition, depending on the location where the electric wire was tied, the band of the previous outfit was removed and the band was put on again, which was a waste.

[0009]

The problem to be solved is that, in the above outfitting method (preceding outfitting), the conventional ladder type electric circuit is installed on the lower surface of the hull block (that is, when the hull block is normally rotated and assembled to the ceiling. We will fix it by welding on the surface (which will be the surface) and take into account later things when laying the wire (it will be inverted upside down later), and lay the wire so that it hangs under the ladder type electric circuit. First of all, it took a lot of work to tie the electric wire to the electric line.

Further, when the electric wire is laid after the hull block has been normally rotated and assembled, the band tied up at the time of the previous outfitting is caught, resulting in an injury of promptly laying the electric wire. When it is necessary to stake the newly added wire at the same place as the band that was shackled at the time of previous outfitting, remove the band that was once shackled and stake it again. There was a waste. By eliminating these wastes, the number of work steps can be shortened and the cost can be reduced.

[0011]
