<p>PURPOSE:To effectively utilize the mounting space of a cable rack by arranging cables on both the upper and lower surfaces of a sub-girder. CONSTITUTION:Sub-girders 2 are arranged perpendicularly to main girders 1a and 1b thereby forming a ladder-like structure, and fastening pieces 5 are attached to both the ends of a binding strip and are attached to the upper and lower surfaces of the sub-girder. In laying the cable, the fastening piece 5 is made slightly loose and the binding strip 4 is held to a temporary fastening state, a gap between the upper and lower surface of each sub-girder and each binding strip 4 is widened, and cables 10 are laid between two gaps. When the laying of the cables 10 is completed, fastening pieces 5 are tightened and the cables are fixed.</p> |
