Combining structure of a cable tray

The present invention relates to a coupling structure of a cable tray for supporting and fixing a cable wired along a wall or ceiling, and more specifically, to maximize the supporting area by a simple coupling structure between the two side frames of the tray and the hanger between the side frames. And it relates to a coupling structure of the cable tray to maximize the rigidity by minimizing the twist in the inner and outer, front and rear direction.

In general, trays are used to organize cables in places where a large number of cables for power supply or fluid supply are provided.

The cable tray is composed of hangers that are coupled at regular intervals between the left and right side frames and the side frames so that the cables are arranged and arranged above the hangers.

However, in the cable tray, the left and right side frames and the hangers caused torsional defects in the inner and outer sides and the front and rear sides due to the cable load. Therefore, a number of techniques have been disclosed for firmly coupling the left and right side frames and the hangers. .

For example, in Patent Registration No. 0689873, in order to couple the left and right side frames and the hangers, slots are formed on the inner side of the left and right side frames, and the bent pieces formed at both ends of the hangers are inserted up and down. It is configured to combine.

At this time, the embossed portion was formed on both sides of the slot to be in close contact with both sides of the bent piece and to reinforce the torsional strength of the side frame and the hanger.

In addition, the Utility Model Registration No. 436286 is to be coupled to each other in the assembly structure, not the fastening structure by the fastening bolt in the Patent Registration No. 0689873, the coupling protrusion formed in the lower side of the bent piece coupled to the flange formed bent in the lower side frame It is configured to have a structure that is inserted into the groove and mutually coupled.

However, since the cable tray has a limited support area between the left and right side frames and the hangers having a cross-section of the "c" shape, the left and right side frames may be inwardly twisted, or the rigid coupling force between the left and right side frames and the hangers may be reduced. It still lacked the problem of the rigidity limit, which caused both ends of the hanger to twist in the front and rear directions.

The present invention is designed to solve the above problems of the prior art, by maximally supporting the area between the left and right side frame and the side frame of the tray by a simple coupling structure mutually minimize the inner, outer, front and rear torsion Its purpose is to maximize robustness.

This invention,

Both ends of the hanger are connected to each other between the left and right side frames,

The hanger forms the shape of the ordinary light bottom narrow to secure a wide support area of the side,

The support bending piece is formed to be doublely supported by the punching and lowering a predetermined size on the outer upper surface to double support the outer bending piece, and a bending end horizontally bent at the lower end of the supporting bending piece is bent inwardly under the side frame. It is achieved by inserting into the hole of the flange and mutually engaging to be supported in the up and down direction.

The present invention is characterized in that at least one bending support portion for supporting the side frame inward on the side outer end of the hanger.

The present invention simplifies a simple coupling structure between the two side frames of the tray and the side frame, but the side by the bending support formed by forming both sides of the hanger in the upper and lower down light structure and cutting the outer end, bending In addition to maximizing the support area of the support frame, in addition to the bent pieces formed at both ends of the hanger, a double support structure by the bent piece bent into the bent piece and the bent end of the bent piece are supported in the up and down direction. It has the effect of maximizing the firmness by minimizing the torsion in the inner and outer, front and rear direction of the side frame and the hanger.
