Abstract

An anchor is provided whose number of processes of work at the time of performance of installation work can be reduced and which can selectively fix a plurality of types of fixing targets. An anchor 10 includes: a shaft 22 to be buried in a ground; a head 24 into which a propulsive force for propelling the shaft 22 in the ground is inputted, the head 24 being provided on an upper end portion 22a of the shaft 22; and a sleeve 26 having a tubular peripheral wall portion 42 placed around the head 24. An outer diameter of the head 24 is specified to be greater than an outer diameter of the shaft 22. Consequently, an undersurface 32a is secured on an outer peripheral portion 32 of the head 24. The peripheral wall portion 42 is provided in an upper end portion 42a with an opening portion 44 in which a first fixing target 12c, 12d, or 12f is fitted as needed. The peripheral wall portion 42 is provided in a lower end portion 42b with a retainer 46 including an opposing surface 48 facing the outer peripheral portion 32 (the undersurface 32a) of the head 24 from below, and a retaining surface 50 to be pressed against a second fixing target 12a or 12b from above as needed.

Dependent claims

An anchor that fixes a fixing target on a ground surface, comprising:

a rod-like shaft to be buried in a ground;
a head into which a propulsive force for propelling the shaft in the ground is inputted, the head being provided, coaxially and integrally with the shaft, on an upper end portion of the shaft;
and
a sleeve including a tubular peripheral wall portion placed around the head, wherein
in plan view, a diameter of a first circumcircle circumscribing the head is specified to be greater than a diameter of a second circumcircle circumscribing the shaft, an undersurface facing downward being formed on an outer peripheral portion of the head,
the peripheral wall portion is provided in an upper end portion thereof with an opening portion into which a first fixing target is to be fitted above the head,
the peripheral wall portion is provided in a lower end portion thereof with a retainer including an opposing surface facing the undersurface formed on the outer peripheral portion of the head from below, and a retaining surface to be pressed against a second fixing target from above, the second fixing target to be fixed on the ground surface, and
an inner peripheral surface of the retainer comprises a hole through which the shaft is inserted, and the hole and the opening portion form a through-hole.
