The raised protrusions 16 are fitted to both end portions of the rungs 6 protruding from the inner surface of the lower concave portion 12 of the side rails 4 and are fastened while reinforcing the supporting force of the rungs 6 by locking. Guide the fasteners 18 to engage through the ball (14).

In addition, a plurality of connection holes 20 are formed side by side at both ends of the bending vertical surface 10 of the side rails 4 so as to connect and fix other cable trays, and one side of the connection hole 20 may be connected to a ground wire. The ground line hole 22 is formed.

Side rail (4) of the present invention configured as described above is smaller than the thickness of the side rail (4) by increasing the tensile force according to the secondary bending forming the vertical surface 10 compared to the simple "c" frame structure of the conventional side rail Even though it can maintain the same strength as the existing equipment standards, it can reduce the production cost due to material savings.

On the other hand, the rung 6 is horizontally installed on both sides of the side rails 4 described above, and is bent into a rectangular tubular body so as to be supported after being caught with the raised protrusions 16 formed on the inner surface of the side rails 4, The opening 24 is formed in the center in the longitudinal direction, and both sides of the opening 24 are formed to have the wings 26.

Both ends of the bent molded rung 6 are fitted with fixing pieces 8 having threaded holes 28 formed therein so that the rung 6 is assembled to the side rails 4 in a prefabricated manner.

That is, the fixing piece 8 to be fixed to the rung 6 is formed to be bent in a "c" shape, but form an assembly piece 30 bent backward on both sides of the body portion, but each of the binding grooves at the upper and lower ends of the assembly piece 30 (32) is formed, and the screw hole 28 is formed in the front part of the main body so that it can be fastened as a nut when screwing with the side rail (4).

And the fixing piece 8 is coupled through the press working to fix to the rung (6). That is, the rear both side assembly pieces 30 of the fixing piece 8 are inserted into the wing parts 26 of the rungs 6 at right angles through both end portions of the rungs 6, and the wing parts 26 of the rungs 6 are provided.
