PROBLEM TO BE SOLVED: To surely and easily joint mutual full PCa floorboards. SOLUTION: A tip part of a main reinforcement 12 is projected as an anchoring reinforcement 13 on a side end surface of both full PCa floorboards 11 to be jointed, and an anchoring leg part 14 bent at a right angle is formed in its tip part. Both anchoring reinforcements are oppositely arranged between mutual stirrups 7 projecting in an upper part of a half PCa beams 1, and a U-shaped anchoring reinforcement 16 is arranged along these reinforcements so as to straddle between these reinforcements. An anchoring leg part 17 of its U-shaped anchoring reinforcement is respectively opposed at a predetermined interval to the anchoring leg part 14 of both anchoring reinforcements, and main reinforcement stress is transmitted via concrete interposed between the anchoring leg parts. Both the anchoring reinforcement and the U-shaped anchoring reinforcement are preferably locked on a beam main reinforcement 8. Both mutual anchoring reinforcements may be directly lapped without using the U-shaped anchoring reinforcement. COPYRIGHT: (C)2006,JPO&NCIPI
