WEDGE BLOCK FOR RESTRAIN APPARATUS AND CONSTRUCTING METHOD USING THE SAME

摘要

The present invention includes first and second surfaces located opposite to each other, and side surfaces formed in a round shape along the circumference between the first and second surfaces, and any one of the first and second surfaces The outer portion adjacent to the outermost edge and the inner portion compared to the outer portion and concavely stepped against the outer portion to accommodate the anchor head and the inner portion compared to the inner portion and located inside the inner portion Block body having a concave stepped contact plate receiving portion; A plurality of tension line through-holes, which are drilled in the thickness direction so as to penetrate the first and second surfaces of the block body and pass the tension line; A contact plate for wedge compression disposed on the contact plate receiving portion of the block body and capable of contacting a fixed wedge of the anchor head accommodated in the inner portion; And an elastic member that is fastened to the wedge compression contact plate and applies an elastic force to the wedge compression contact plate in a direction to compress the fixed wedge.
