PROBLEM TO BE SOLVED: To provide a pile foundation structure capable of preventing a pile structure from being deformed when it is installed by striking, and of absorbing the construction error in the plane direction and the height direction of the pile structure and a superstructure without increasing labor for construction, and of supporting the superstructure firmly.SOLUTION: A pile foundation structure 7 supports a superstructure 6 by a pile structure 1 of a steel pipe pile 2 installed by striking. The pile foundation structure 7 comprises: a steel pipe pile 2 in which a pile head plate 3 receiving a striking force is mounted on a head 2a; and a plane error absorption material 4 connected to the pile head plate 3. The pile head plate 3 has: a striking force reception part 31 with its top face 31a formed to be nearly flat; and a female screw part 33 provided together with a plate bolt hole 32 penetrating through the striking force reception part 31 and formed. The plane error absorption material 4 has adjustment surface parts 41, 42 in which plane surface adjustment holes 46, 47 are respectively formed and which are movable in the plane direction, and is fixed to the striking force reception part 31 of the pile head plate 3 by coupling a connection bolt 11 with the female screw part 33. |
