PILE HEAD JOINT STRUCTURE

Japanese Patent JP2018141356

A

PROBLEM TO BE SOLVED: To provide a pile head joint structure that can efficiently reinforce a joint part of a pile head part of a foundation pile and foundation concrete; and in which reinforcing bars made of materials with poor weldability can be used and the number of the reinforcing bars can be reduced; and that can achieve elimination of overcrowding arrangement of the reinforcing bars above the pile head.SOLUTION: A pile head joint structure 40 joining a foundation pile 44 and foundation concrete 48 integrally includes a plurality of joint members 42 to which lower ends of reinforcing bars 46 are joined. The plurality of joint members 42 are joined to an outer peripheral surface 44b of a pile head 44a such that they are spaced apart, and a length in a direction corresponding to a circumferential direction of the pile head 44a is longer than a length in a direction corresponding to a radial direction of the pile head 44a. Each of the joint members 42 is formed by a single solid member that has an upper surface substantially in parallel with an upper end surface of the pile head 44a and a lateral surface facing the outer peripheral surface 44b. On the upper surface of the joint member 42, a plurality of through holes into which the lower ends of the reinforcing bars 46 can be inserted are formed.SELECTED DRAWING: Figure 1
