CONSTRUCTION METHOD FOR ANCHOR

PURPOSE:To easily pull an anchor out of an object being constructed. CONSTITUTION:In the case where a locking part 4 divided into an upper half part 2 and a lower half part 3, which is bounded by a cut part 1 cut at an acute angle, is allowed to shift laterally in a hole 5 formed on an object to be constructed, the upper and lower half parts 2, 3 are allowed to shift within the range of a lateral movement clearance J formed between inner surf aces 2c, 3c of the upper and lower half parts 2, 3 and the outer surface 6a of a bolt part 6 passed through inside them when the longitudinal movement of the upper and lower half parts 2, 3 is stopped. On the other hand, when force applied to the upper half part 2 is released, the upper and lower parts 2, 3 return from the state of lateral movement to the former state, and the bolt part 6 and the locking part 4 can be removed from the hole 5.
