Description

[Detailed description of the invention] This invention relates to cable racks, and is particularly concerned with the improvement of cable racks used when piping and wiring wiring materials such as conduits and cables to buildings, station buildings, and other structures. This is intended to prevent the wiring material being wired from sagging and to strengthen its robustness.

In other words, the gist of this invention is to provide a pair of band-shaped master girder members, each of which has a mounting step along its inner lower part and a reinforcing part as appropriate, and an opening with a protruding engaging edge. A sub-girder member is installed between the main girder members in a state perpendicular to the main girder members, and has a substantially C-shaped cross section with the section open along its longitudinal direction, and a child girder member that is installed perpendicularly to the main girder members, and a The present invention consists of a bottom plate member on which the edge is placed, which is fixed to the child girder member and which is laid between the parent girder members.Hereinafter, embodiments of this invention will be described with reference to the drawings. Then, it is as follows.

Reference numeral 1 shown in the figure is a strip-shaped main girder member, which has a mounting step portion 2 along its inner lower portion and a reinforcing portion 3 as appropriate. The mounting step portion 2 is set at a height approximately equal to the thickness of the bottom plate member 7, which will be described later, and is obtained by bending the lower edge of the main girder member 1 into an L-shape. The reinforcing part 3 has an L-shaped cross section, a T-shaped cross section, etc. on the upper and lower edges of the main girder member 1 itself, so as to effectively prevent the main girder member 1 itself from being bent or distorted in the longitudinal direction. It is formed by protruding into an appropriate shape, or by protruding in a U-shape halfway in the height direction toward the outside and inside.

A plurality of child girder members 4 are installed in parallel between the parent girder members 1 so as to be orthogonal to the parent girder members 1.
Approximate cross-sectional angle C opened along its own longitudinal direction
It is formed into a letter shape. The construction of the child spar member 4 is carried out by fitting and welding the ends of the child spar member 4 into the connection recess 1A obtained by forming a groove-shaped bend in the inner lower part of the parent spar member 1. .

Further, as shown in FIGS. 1 and 3, the child spar members 4 are arranged in parallel orthogonally to the longitudinal direction of the main spar member 1, with the openings 6 thereof facing upward and downward. By this, the downward child beam member 4
is used for fixing to the bottom plate member 7 disposed below this 4, and the upward child beam member 4 is used to secure wiring materials W such as conduits and cables to be passed on the child beam member 4. This is useful for engaging the clip C that fixes the clip.

Reference numeral 7 denotes a bottom plate member, whose both side edges are placed on the above-mentioned stage mounting portion 2, fixed to the child spar member 4, and laid between the main spar members 1, and if necessary, breathable. A large number of through holes are sometimes drilled to reduce weight and to connect and fix various parts.

At this time, the bottom plate member 7 is fixed to the child spar member 4 and has a substantially parallelogram shape in plan view having a width smaller than the width of the gap between the engaging edges 5 at the opening 6 of the child spar member 4 and a longitudinal width larger than the width. The locking plate 8 is inserted into the opening 6 from the gap between the engaging edges 5, while,
The fixing screws 9 passed through the bottom plate member 7 are screwed into the locking plate 8 and rotated to abut and engage with the inner surface of the engagement edge 5, thereby fixing the child beam member 4 and the bottom plate member 7. (See Figures 2 to 4).

In addition, in the figure, S is a separator member having a substantially hat-shaped cross section, and is mounted on the sub-spar member 4 with mounting screws 10 passed through the bottom plate member 7 or the sub-spar member 4, and is used for control purposes, electric power, etc. The wiring materials W are classified according to type.

This invention is constructed as described above, and its assembly will be explained below.A pair of band-shaped main beam members 1 are arranged in parallel to face each other, and a bottom plate member 7 is placed between them.
, by placing and engaging both side edges with the mounting step part 2, and with the opening 6 facing downward, and depending on the location, facing upward, both ends are welded to the inner lower part of the main girder member 1. By other coupling means, the child spar member 4
and furthermore, the bottom plate member 7 is constructed under the sub-girder member 4.
8, 9. In addition, the bottom plate member 7
may be laid by sliding and inserting the main spar member 1 from the length direction of the main spar member 1 after assembling both the main spar member 1 and the child spar member 4.

Therefore, since the bottom plate member 7 is fixed to the child girder member 4 and laid between the parent girder members 1, the wired wiring material W is securely placed on the child girder member 4 or the bottom plate member 7. The rack will not hang downward, the wiring material W will not be exposed, and the appearance will be good.

Since it is basically ladder-shaped, it has enough robustness to withstand the load of the wiring material W, and furthermore, the bottom plate member 7 is fixed to the child beam member 4, increasing the overall robustness. In addition, it is extremely effective in preventing distortion. Not only that, but
Since the bottom plate member 7 is placed in the mounting step 2 along the inner lower part of the main girder member 1, the connection during assembly is stable. is formed, and the cross section of the child spar member 4 itself is approximately C-shaped, and the child spar member 4
Because the increase in its own mechanical strength is taken into account,
For this reason, there is no risk of deformation after assembly or disassembly due to external shocks or vibrations.

As explained above, according to this invention, since it is assembled from the parent girder member, child girder member, and bottom plate member, the connection between them is tight and stable, and is not easily deformed, and the wiring material for passing the wires is This has extremely beneficial effects in practical terms, such as preventing the material from sagging and improving the appearance by not exposing the material.
