PURPOSE: A linear type removable anchor head is provided to enable retightening of a PC strand by hitting the exposed part of the PC strand after releasing the PC strand. CONSTITUTION: A linear type removable anchor head able to be reinstalled by hitting comprises a cylinder(10), a split wedge(20), a pulling unit(30), a spring(40), and a cylinder cap(50). The pulling unit pulls the split wedge by moving along a ring-shaped guide groove(510). The spring is located between the other end of the pulling unit and one side of the cylinder cap and provides an elastic force for the pulling unit not to retract naturally. The cylinder cap is formed in a cylinder shape with one side open and the other closed and is coupled with the cylinder to form an exterior shape of the anchor head. |
