PROBLEM TO BE SOLVED: To provide a construction method in which a worker does not have to get into a clearance to perform removal work. SOLUTION: When placing a concrete form 2 on a foundation 9 in constructing a concrete floor 1, posts 5 tapered toward the tips are erected on the foundation 9, placing the tapered tips on the top side, and sleepers 4 and joists 3 are placed thereon for erection. Before placing the concrete form 2 on the joists 3, the joists 3, the sleepers 4 and the posts 5 are tied with cords 10 or the like, and ends 10a of the cords are put outside from a partially cutout open part of a foundation peripheral cover 11. When the concrete floor 1 is horizontally moved by a jack 12 or the like after the completion of a building, the posts 5 incline, and the joists 3 and the sleepers 4 are displaced sideways and fall. The removal of the posts 5, joists 3 and sleepers 4 that have fallen on the foundation from under the floor is performed by pulling the cords 10a tied in construction. COPYRIGHT: (C)2006,JPO&NCIPI
