Earth-Anchor Apparatus for Slope-Reinforcement-Construction

摘要

In the present design in the earth anchor structure for ground reinforcement steel construction or structural support, it is inserted into the hole by being extended to the inner circumference sufficient coupling rigidity of the expansion anchor and the anchor body to aid the fixation of the tension member in the ground, and more conveniently extended portion extended in the hole, the construction is simple earth anchor structure is disclosed by.; Between the subject innovation for this is the tapered cone 12, the uiha steel wire 10, is provided an anchor cap 16 to the front end of the anchor body 14 can be combined with the anchor cap 16 and the anchor body 10 expansion anchor (20) is radially protruded into the elastic force of the spring 18 is installed, and so that the support body in which the anchor cap supporting the expansion anchor (20) for the tension of the steel wire, the inner end of the expansion anchor (20) There is a locking opening (22) to allow the radially projecting installed is inserted into the anchor body 10 to disable it with a box for holding the inserted state.; In one embodiment, the expansion anchor 20 is installed so as to project rotated by the torsion spring the bolt shaft (24) for engagement of an anchor cap (16) and the anchor body 20 in the rotary shaft, extended in other embodiments anchor 20 includes a guide groove 26 that provides a straight path for projecting the expansion anchor 20 into the anchor body 14 is formed, with soon as the expansion anchor 20 is inserted here above with the front end opening expansion anchor (20) protrudes so that the elastic spring-loaded and expansion anchor 20 is provided that is formed a locking projection (28) that works with the elastic spring.
