PROBLEM TO BE SOLVED: To fully fill concrete in joint clearance, in a PC member using a tapered tile having rear edge side on a butt end surface tapered. SOLUTION: A plurality of tiles 2, 2, 2 are arranged on a bed 1 at a prescribed interval with their rear surfaces directed upward, a temporary joint material 4 is filled in between tiles 2, 2, and a highly flowable concrete 3 is casted from above, to integrate the concrete 3 to the tile 2, thereby obtaining a PC plate having the plurality of tiles 2, 2, 2 integrally stuck on the top surface of the concrete 3. Dovetail grooves 2d are provided on the rear surface of tiles 2 to projectingly form dovetail reverse feets 2a, 2a, 2a. The tapered surface 2b is formed on the rear edge side of the butt end surface of each tile 2. COPYRIGHT: (C)2008,JPO&INPIT
