PROBLEM TO BE SOLVED: To anchor a prestress introducing steel material of a Y-shaped prestressed concrete pressure receiving plate in a substantially central part of an end part cross section of the pressure receiving plate. SOLUTION: PC steel stranded wires 21, 22 and 23 are used as the prestress introducing steel material of the Y-shaped pressure receiving plate 1, and are arranged in a U turn curvedly arranged in a V shape. Since curved arrangement can be performed, the PC steel stranded wires is anchored in the substantially central part of the end part cross sections 31, 32 and 33 of a leg. Thus, the end surface cross-sectional area is not required to be enlarged, and a cover is sufficiently taken without increasing weight. COPYRIGHT: (C)2008,JPO&INPIT
