ANCHOR PILE, BUILDING FOUNDATION STRUCTURE, AND CONSTRUCTION METHOD OF BUILDING FOUNDATION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an anchor pile that is devised to enhance shearing performance, while suppressing an increase of weight.SOLUTION: An anchor pile 1 is buried in the ground from a lower end by rotating about a shaft center, and having an upper end side connected to a supporting member for supporting a building. The anchor pile includes: a buried part 11 buried in the ground; a head 13 provided above the buried part 11; an excavation blade 14 helically provided toward the shaft center direction along which the shaft center extends, on the lower end side of the buried part 11; and a resistance blade 15 helically provided toward the shaft center direction between the excavation blade 14 and the head 13. The resistance blade 15 includes cutout parts 151 that are cut out to the side of the buried part 11 at intervals in the helical revolving direction, and an attitude stabilizing part 152 sandwiched between the cutout parts 151 adjacent to each other in the revolving direction.
