<p>PURPOSE:To increase safety of fitting works of handrails in an opening curing. CONSTITUTION:A setting piece 5 is provided at the upper end of an insert 7 and fixed at a mold 3 so that the insert 7 turns upward. And then, concrete is placed and the handrail 11 is connected to the insert 7. The joint metal 17 of the insert 7 and the handrail 11 is constituted by jointing a protruded piece 15 fitted to a handrail pipe 11 at the upper end of a bolt 9 or the like. The setting piece 5 bent to form an L-shape in time section is easily handled. Since the bending stress of the protruded piece 15 is received on the concrete face, if a collar 13 is provided at the bottom edge of protruded piece 15, the strength is increased.</p> |
