Combination of successive portions of a cable tray of plastic materials and assembly means of said portions, and procedure for the realization of this combination.

摘要

The method according to the invention consists in placing at least two sections (1) of cable ducting end to end, in engaging a first fish plate (2) obliquely so that its first wing (21) is in contact with the rim (13) of the two sections, the shoulder (21a) of the said wing being in engagement with the internal rib (13a) of the rim of these sections, then in making the fish plate (2) pivot by deforming it elastically so that its bottom comes to bear against the corresponding wing of the sections whereas the free edge (22a) of the second wing (22) of the fish plate (2) comes into abutment against the step (15a) of the bottom (10) of the sections (1), and finally in placing a second fish plate opposite the first one in the same way.
