Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an improvement of a cable rack for installing cables.

[Technical background of the invention and its problems]

At substations, power cables, control cables,
Electrical equipment inside and outside the building is connected by numerous cables such as communication cables. In this case, in order to save space in the building and ensure usable space, the cables are generally installed on cable racks installed inside or outside the building.

FIG. 1 shows an example of the conventional configuration of the above-mentioned cable rack, and shows the distance between the first and second elongated bodies 3A and 3B, which are suspended from the ceiling 1 by the hanging body 2, in the extending direction. It has a structure in which the horizontal frame 4 is installed. In the cable rack having such a configuration, the cable 5 is installed in a substantially U-shaped space formed by the first and second elongated bodies 3A, 3B and the horizontal frame 4.

By the way, in the case of the above-mentioned cable rack, when it becomes necessary to increase the number of cables 5 installed, it is generally done to stack the cables 5 in a plurality of stages. However, when the cables 5 are stacked in multiple stages, the heat dissipation characteristics of the cables 5 deteriorate, and the cables 5
This will damage the insulation. As a result, the original purpose of the cable 5, which is to supply power and transmit signals, may not be carried out satisfactorily in some cases, and there are concerns about insulation failure and fire.

[Purpose of invention]

This invention was made based on the above circumstances,
To provide a cable rack having a simple configuration and capable of erecting a large number of cables.

[Summary of the idea]

In order to achieve the above-mentioned object, the cable rack according to the present invention has a horizontal frame constructed at a distance from each other in the extending direction of the first and second elongated bodies, and one end of which is bent and the other end of the joint. is fixed to the horizontal frame body by a connecting body.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a perspective view showing an embodiment of the cable rack according to the present invention.

In FIG. 2, 6A and 6B are first and second elongated bodies each having a predetermined width dimension and arranged substantially parallel to each other. 7 supports cables (not shown) disposed in the longitudinal direction of the first and second elongated bodies 6A and 6B;
It is a horizontal body that is provided at an appropriate distance in the longitudinal direction and spans the widthwise lower part of each of the first and second elongated bodies 6A and 6B. 8 is a joint formed in a substantially L-shape, one end of this joint 8 is placed on the upper horizontal frame 7, and a bent portion 8A on the other end is connected to the first and second elongated body 6A. , 6B. Reference numeral 9 denotes a connecting body that fixes the horizontal frame 7 and one end side of the joint body 8. This connection body 9
As the details are shown in FIG. 3, a nut 9B is fixed to a piece of the base portion 9A formed in a substantially U-shape,
A bolt 9C is screwed into the nut 9B, and the horizontal frame 7 and the joint 8 are fixed by the tip of the nut 9B. Reference numeral 10 denotes a hanging body that supports the first and second elongated bodies 6A and 6B, respectively, and is hung from the ceiling of a building (not shown).

Next, the operation of this embodiment configured as described above will be described.

That is, according to this embodiment, the first and second elongated bodies 6
A, 6B and the horizontal frame 7 form a substantially U-shaped first space, and a second elongated body 6B and the joint body 8 are formed.
Since a substantially U-shaped second space is formed, a large number of cables can be installed in the first and second spaces, and there is no need to stack cables, so the heat dissipation characteristics are improved. Becomes good.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the shape of each member can be modified in various ways, and the material can be implemented using various materials depending on the type of cable and the number of cables to be installed. It is possible. In addition, various modifications can be made without changing the gist of the present invention.

[Effect of idea]

As described above, according to the present invention, the first and second
A plurality of horizontal frames are provided at appropriate distances in the longitudinal direction of the elongated body, and the other end of the joint body with one end side bent is fixed to the horizontal frame body by a connecting body. Therefore, the cable is placed in the space formed by the first and second elongated bodies and the horizontal frame, and the space formed by the first or second elongated body and the bent portion of the joint body. It is possible to provide a cable rack that can be easily constructed and that can accommodate a large number of cables.
