CONSTRUCTION SYSTEM CONSISTING OF COLD-FORMED SECTIONS WITH EDGES CORRUGATED AT A CONSTANT INTERVAL, AND CONNECTING AND FIXING DEVICES ENGAGING WITH THESE

摘要

Two or more elementary sections are permanently assembled together to form continuous longitudinal slots with their longitudinal edges (25) facing inwards and each inclined towards the opposite edge so that they converge inwardly; fixing devices (31, 35) comprise a receiving matrix or plate (31) forming a channel with walls (31A) inclined in the same way as the said edges (25) and one or more locking plugs or plates (35) which also have lateral walls inclined in the same way as the said edges; the devices may be fixed along the slots to grip the edges (25) by screw means between matrices (31) and plugs (35); the said longitudinal edges (25) of the elementary sections have corrugations corresponding to corrugations which are present in the walls (31A) of the matrices (31) and in the lateral walls of the plugs (35).
