PROBLEM TO BE SOLVED: To provide a pile head joint technology which dispenses with welding work at a construction site, is easy in construction, and can construct a rigid pile head joint structure.SOLUTION: A pile head joint structure 100 is formed by attaching a pile head joint member 10 to a pile head 1a in a state of being embedded in the ground G and protruded from the ground surface G1. The pile head joint member 10 comprises: a main body part 11 which is inserted into a pile material 1 from an upper-end opening part of the pile material 1; a locking part 12 which is engaged with the upper-end opening part of the pile material 1, and radially extends toward an external peripheral region of the pile head 1a from the main body part 11 in order to hold the main body part 11 at a prescribed position; a disc-plate shape lid body 13 which is arranged at a lower end part of the main body part 11 in order to block the inside of the pile material 1 to a traverse direction; and a reinforcing part 14 which is arranged at a tip of the locking part 12. The main body part 11 and the locking part 12 are formed of flat plate materials having a plurality of penetration holes H, and the reinforcing part 14 is formed of a flat plate material having a plane part in a vertical direction.SELECTED DRAWING: Figure 2 |
