<p>PROBLEM TO BE SOLVED: To sink a terminal of temporary electric wiring in concrete completely by disposing a space forming means around the temporary electric wiring in the concrete, cutting the temporary electric wiring in the space of the space forming means when the temporary electric wiring becomes unnecessary, and filling the space with mortar. SOLUTION: A slab cap 13 is fitted, as a space forming means, around a temporary electric wiring 12 which is embedded in the concrete 11 of a building. The slab cap 13 is disposed by adjusting the end edge of a skirt part 21 to the end surface of the concrete 11. A seal part 24 comes into close contact with the temporary electric wiring 12 and prevents the concrete 11 from invading into the slab cap 13 at the time of placing the concrete. Ribs 28A, 28B, 29A, and 29B formed inside and outside the skirt part 21 prevent the skirt part 21 from being damaged. If the temporary electric wiring 12 becomes unnecessary, the temporary electric wiring 12 is cut in the space of the skirt part 21, and the space is filled with mortar 14 to sink the terminal of the temporary electric wiring 12.</p> |
