PURPOSE: A structure of a removal nail is provided to remove a removal member and a reinforcing bar easily and to shorten a period of works. CONSTITUTION: The structure of a removal nail comprises a deformed bar composed of a rib and a joint to prevent sliding when adding force on a reinforcing bar in concrete or grout, a removal member for preventing the separation of the deformed bar when a removal nail functions as a stiffener and removing a removal member to secure a space for the deformed bar to be removed when removing the deformed bar, covers and a shrinkable tube(161) for preventing the permeation of grout and transferring force without the grout and the deformed bar are not in contact directly. The removal nail is manufactured by assembling a deformed bar, a removal member and a cover, then putting in a shrinkable tube and spray hot water or adding a hot wind to shrink the shrinkable tube to be adhered closely.
