<p>PROBLEM TO BE SOLVED: To cause metal fixtures to have a large surface rigidity which enables sure cable support by providing a square pipe to be fixed to an angle strut, a supporting tray which is formed by pressing a metal board and covers the square pipe, and strong skeleton members formed by bending metal boards into a cubic shape and fixed to the supporting tray. SOLUTION: In the base of a rigid square pipe 1, a slot 2 is formed, and fixing boards 3 are welded to the slot 2, and the fixing boards 3 separated by the thickness of an angle strut B are firmly fixed to the fixing holes of the strut B using fixing bolts 4 and nuts 5. Cable supporting metal fixtures are provided with a supporting tray 6 formed by pressing a thin metal board into a dishlike shape, reinforced with strong skeleton members 7 fixed to the bottom surface of the supporting tray 6 having a small surface rigidity, and fixed to the square pipe 1 through the members 7. Consequently, stable support of a heavy-weight cable becomes feasible.</p> |
