IMPLEMENTATION OF A USEFUL MODEL

As shown in FIG. 1-4, a tray for mounting and stacking electrical cables, contains:

spars, which are bent metal profiles of box-shaped cross-section, having a neck and at least two shelves, while the said spars are parallel to each other at a distance from each other, and

rungs located essentially perpendicular to said spars, wherein each of said rungs has an end provided with bends oriented substantially in the plane of the neck of said runners;

wherein:

the neck of said spars is provided with pockets having slots, while

said bends of the crossbars are connected to said spars in such a way that said bends are installed inside said pockets through said slots.

Each element of the ladder-type tray for power lines and / or communication lines contains perforated spars 1, 5 made of a metal strip with connecting nodes 2 and perforated crossbars 4. Spars 1 and 5 (conventionally left and right) are interconnected by means of the said crossbars 4.

The connecting unit 2 contains two stamped elements 3, forming a pocket and located mirror-image relative to each other.

Element 3 is a part of the spar 1, displaced in the inner direction parallel to forming the surfaces of the spar 1 at a distance of 1.0 to 3.3 mm, while when joining the elements of the ladder-type tray for power lines and / or communication lines, the bends of the crossbars 4 closely adjacent to the inner surface of the pocket 3.

When assembling the tray from the finished side members and crossbars, the end of the crossbar is connected to the side member in essentially one movement - by setting the bends at the end of the crossbar in two suitably located pockets.

After this, the connection can be further strengthened by known methods: welding, clinching, rivets, etc.
