<p>PROBLEM TO BE SOLVED: To resolve a problem that when a concrete wall is pierced with a cable or a synthetic resin pipe for electric construction between partitioned rooms, the synthetic resin pipe is normally embedded in a ceiling body with an end cover, so that not only work efficiency is low due to considerable height in passing wires but piping work in the ceiling body carried out in a limited period is increased. SOLUTION: In a process of the construction of the concrete wall, wall tentative frames are built, and in order to set the distance between both the tentative frames constant and to withstand the load of the concrete in placing, pipe support members 17 each provided with a cover member 14 abutting on the tentative frame, and a pipe fixing part 15 and a support fixing part 16 on the opposite sides are connected to a support bar 11 provided with an adjustment ring 10 having both its ends threaded for adjusting the wall thickness through the synthetic resin pipe 3 and they are fixed with nuts, screws and binding wires.</p> |
