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 member 10 comprises: a main body part 11 which is inserted into a pile material 1 from an upper-end opening part 1b of the pile material 1; a lower lid body 12 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 an upper lid body 13 which is engaged with an upper part of the upper-end opening part 1b of the pile material 1 in a flange shape, and arranged at an upper end part of the main body part 11 in order to hold the main body part 11 at a prescribed position. The main body part 11 is formed of a cylindrical body having a plurality of penetration holes H, the lower lid body 12 is formed of a disc-plate shape plate material, and a plurality of reinforcing parts 14 which are formed of flat plate materials having a plurality of penetration holes H are erected on an upper surface of the upper lid body 13. The pile head joint member 10 is attached to a pile head 1a being a head part of the pile material 1 in a state of being embedded in the ground and protruded from the ground surface, and a pile head joint structure is constructed.SELECTED DRAWING: Figure 1 |
