PRECAST CONCRETE FOUNDATION BLOCK AND JOINT STRUCTURE FOR THE SAME
To provide a precast concrete foundation block and joint structure for the same in which a position of a screwed flange is freely adjusted with respect to joint main reinforcements, and that can easily establish a desired position relationship between the screwed flange and a hollow joint member that connects right and left joint main reinforcements.SOLUTION: A precast concrete foundation block 10 forms the raised section of a foundation. Part of a top reinforcement 11 and a vertical reinforcement 13, which are arranged in the foundation extending direction, are embedded in concrete 15. On an end 16 of the precast concrete foundation block 10 in the extending direction, a first recess 17 is provided in a position corresponding to the top reinforcement 11. One end of a joint main reinforcement 20, which overlaps the top reinforcement 11 in the concrete 15 by the length of an overlap joint, protrudes toward the first recess 17, and an end of the joint main reinforcement 20 is provided with a screw groove 21 and a screwed flange 30 is screwed to the screw groove 21.SELECTED DRAWING: Figure 1
【課題】継手主筋に対して被螺合フランジの位置調整が自在となり、左右の継手主筋を繋ぐ中空の接合部材と被螺合フランジの間における所望の位置関係を容易に形成することができるプレキャストコンクリート基礎ブロックとその接合構造を提供すること。【解決手段】基礎の立ち上り部を形成するプレキャストコンクリート基礎ブロック１０であり、基礎の延設方向に延びる上端筋１１と縦筋１３の一部がコンクリート５に埋設され、プレキャストコンクリート基礎ブロック１０の延設方向の端部１６のうち、上端筋１１に対応する位置に第一凹部１７が設けられ、コンクリート１５内において上端筋１１に重ね継手長さラップしている継手主筋２０の一端が第一凹部１７に突出し、継手主筋２０の一端には螺子溝２１が設けられ、螺子溝２１に被螺合フランジ３０が螺合している。【選択図】図１
