摘要

PROBLEM TO BE SOLVED: To provide a structure for joining a PHC (Prestressed High-strength Concrete) pile and a foundation together, which can improve performance of transferring a load to the PHC pile from filling concrete.;SOLUTION: In a structure 10 for joining a PHC (Prestressed High-strength Concrete) pile 20 and a foundation 1 together, filling concrete 24 is placed inside at least a head of the PHC pile 20. The structure 10 includes a small-diameter portion 30 which is provided to be housed on the inside-diameter side of the PHC pile 20, which joins the filling concrete 24 and the foundation 1 together and which has a diameter smaller than the inside diameter of the PHC pile 20, and a deformed bar 14 which serves as displacement prevention means for preventing displacement between the PHC pile 20 and the filling concrete 24.;COPYRIGHT: (C)2012,JPO&INPIT
