Description

[Detailed description of the invention] This invention relates to a cable distribution shelf, which is used to bundle and guide various cables when wiring them in buildings, factories, and other architectural structures, and the cables themselves are By taking into account the deflection caused by the wire, it will have an appropriate shape when the wire is drawn in, and will have good support stability, load resistance, robustness, and ease of connection with suspension rod members such as suspension bolts. This relates to an improved cable distribution shelf.

As one of the conventionally provided wiring shelves of this type, as shown in FIG. There was one that was integrally formed into the shape.

In this type, the main girder part 11 is perpendicular to the installation surface, and the child girder part 12 is horizontal, and the former part 11 is arranged vertically from both sides of the latter part 120, which is formed horizontally. It is manufactured by bending the plate material, integrally forming it by extrusion molding means, and further extruding synthetic resin.

However, with such conventional products, when the cable W is drawn in after being installed in a building, factory, or other architectural structure by suspending, supporting, connecting, etc., the load causes The girder portions 12 were bent, and the parent girder portions 11 were sometimes tilted inwardly relative to each other.

Therefore, the wiring shelf lacks support stability, load resistance, and robustness, and there is a risk that the wiring shelf itself may fall off when it is connected and supported by a hanging rod member such as a hanging bolt at the main girder portion 11.

Therefore, this idea was created in consideration of the existing drawbacks as mentioned above.
This problem was successfully solved by expanding and tilting the main girder part outward by that angle in response to the collapse angle of the main girder part due to the load of the cable being led in. Embodiments of this invention will be described below with reference to the drawings.

Reference numeral 1 shown in the figure is a master beam part located on both sides and facing each other, which is connected to both sides of a child beam part 20 located at the bottom, and both 1 and 2 are integrally formed. The cross-sectional shape of is approximately groove-shaped.

Further, it is usually manufactured by bending a plate material having an appropriate thickness, integrally forming it by extrusion molding means, or further extruding a synthetic resin.

The main girder part 1 is expanded and tilted outward by the angle corresponding to the inclination angle of the main girder part 1 itself when the whole body is bent due to the load of the cable W being led through.

In other words, the load of the cable W that has been led in is
When the main girder parts 1, which are vertically connected to the child girder parts 2, collapse inwardly as the child girder part 2 bends in a bulging manner in the load direction, the installation surface It is inclined outwardly by an angle corresponding to the inclination angle with respect to the original position if it had been formed perpendicularly to the original position.

Therefore, it is desirable that the main girder part 1 itself be appropriately reinforced, for example by bending its upper edge in a folded manner as shown in FIG. 5, or by bending its upper edge as shown in FIG. It can be bent outward in a cross-sectional shape, its upper edge can be bent inward in a cross-sectional shape as shown in Figure 7, or its upper edge can be bent in an outward direction as shown in Figure 8. A reinforcing edge 3 is provided by bending the reinforcing edge 3 into a U-shaped cross section, or by bending its upper edge inward to have a U-shaped cross section as shown in FIG.

In addition, if necessary, the base of the main girder part 10, that is, the continuous part with the child girder part 2, is formed into an arcuate cross section and a reinforcing part 4 that bulges outward to more effectively exhibit the lodging and inclination function. It also becomes possible to increase the reinforcement of this region.

Next, to explain its use, it is laid by suspending, supporting, and connecting it to a building structure in accordance with the usual method, and then the cable W can be led onto the sub-girder section 2.

At this time, when the cable W load is applied to the child girder part 2, the child girder part 2 itself bends due to this load, and the parent girder parts 1 correspondingly collapse and incline toward the inside of the parent girder part 2. The girder portion 1 is positioned substantially perpendicular to the installation surface.

(See Figure 4). Therefore, when the cable W load is applied, the entire body assumes an appropriate shape, and in particular, since the main girder part 1 is positioned approximately perpendicular to the installation surface, a suspension rod member such as a suspension bolt can be attached via this part 1. When suspended or connected, it has excellent support stability, load resistance, and robustness, and has the advantage of being easy to connect.

This is because the main girder portion 1 is expanded and tilted outward by the angle corresponding to the lodging angle accompanying the load of the cable W being led in, and as a result, the cable W is This is because by leading the wires through, the shape becomes suitable for supporting the load, and the wiring shelf itself becomes extremely stable without the risk of falling off.

In addition, the fact that the main girder part 1 is expanded outwardly and tilted allows the wiring shelves themselves to be stacked so as to be fitted in the height direction, and it is extremely easy to transport and store since it does not take up much space. In addition to being convenient, it can also be manufactured at a low cost since it can be manufactured using conventional means and no special manufacturing process is required.

As explained above, according to this invention, when storing and wiring cables in a building structure, the wiring shelf itself assumes an appropriate shape when the cable is led through, thereby improving support stability and load capacity. , it has good robustness and ease of connection, reliably supports the cable load without falling off, is not bulky even when stacked, is convenient for transportation and storage, and is easy to manufacture and can be provided at low cost. Above all, it has extremely beneficial effects.
