Abstract:
Provided is an anchor with which the number of work steps during construction can be reduced and multiple types of fixed objects can be selectively fixed. An anchor 10 comprises a shaft 22 embedded in the ground, a head 24 that is provided to an upper end 22a of the shaft 22 and that receives input of propulsive force for propelling the shaft 22 underground, and a sleeve 26 having a cylindrical peripheral wall 42 disposed around the periphery of the head 24. The outer diameter of the head 24 is greater than the outer diameter of the shaft 22, which ensures a lower surface 32a in an outer peripheral part 32 of the head 24. An upper end 42a of the peripheral wall 42 is provided with an opening 44 into which first fixed objects 12c, 12d, 12f are fitted as necessary. A lower end 42b of the peripheral wall 42 is provided with a pressing part 46 having an opposing surface 48 that opposes the outer peripheral part 32 (lower surface 32a) of the head 24 from below and a pressing surface 50 that is pressed against second fixed objects 12a, 12b from above as necessary.
