COMPRESSION TYPE PERMANENT ANCHOR

PURPOSE: To surely hold the proper stress transfer state to a bearing body from a PC steel wire and enhance the quality of the whole anchor part. CONSTITUTION: In order to make sure of perpendicularity between a bearing body 3 and a PC steel wire 2, a binding grip 4 of the PC steel wire 2 is stored in a storing space 5 of the bearing body 3 separately. A closing cover 6 is mounted to the storing space 5, and a spring 7 is provided the binding grip 4 and cover 6 to push always the binding grip 4 in the direction of the bearing body 3. In addition, the binding grip 4 is fixed with rust proof grease 9 injected in the storing space 5 from an injection hole 8 of the cover 6. The binding grip 4 is vertically fixed firmly to the bearing body 3, fixing strength between the bearing body 3 and PC steel wire 2 (binding grip) is increased, and even if the bearing body 3 and PC steel wire 2 are roughly treated, the PC steel wire 2 is surely fixed to the bearing body in an unmovable state. The rust on the binding grip 4 and PC steel wire 2 is prevented by the rustproof grease 9 in the storing space 5.
