PILE HEAD JOINT STRUCTURE

PROBLEM TO BE SOLVED: To provide a joint structure between a pile head and a structure side by which the joint part between the pile head and the structure side is minimized by reducing buried lengths of pile head anchors, interference with reinforcing bars, anchor bolts or the like of the surrounding structure is reduced, and freedom in designing the structure is increased, while maintaining joint strength required for the joint structure between the pile head and the structure side. SOLUTION: The buried lengths of the pile head anchors 4 provided on the pile head are set to be shorter so that anchor capacities based on the conical breakag S of concrete caused to be centered in anchor plates 5 provided on the pile head anchors 4 may be smaller than the tensile strength of the pile head anchors 4. Further, the anchor capacities of the pile head anchors 4 are made to be larger than the tensile strength of the pile head anchors 4 by arranging a basket-shaped reinforcement 7 comprising vertical reinforcing bars 8 and horizontal reinforcing bars 9 on at least outer peripheral sides of the pile head anchors 4.
