<p>PROBLEM TO BE SOLVED: To easily connect supports with each other and easily establish electrical continuity between the supports. SOLUTION: A coupling device for the supports for wiring and piping materials comprises a main beam member 2 installed along an installation path of a cable C; the support 1 made of a metallic material attached to the main beam member 2 and provided with a cross-arm member 5 forming the installation path of the cable C; and a coupling member 11 made of a metallic material for coupling the supports 1 with each other. Grooves 2a into which screws 12 are forcedly driven are formed in the main beam member 2 in the direction of the length. The screws 12 are forcedly driven into the grooves 2a via the coupling members 11 in between, and the supports 1 are thereby coupled with each other.</p> |
