Abstract
PURPOSE: To provide an anchor so constituted that it exhibits an assured supporting effect during its use and it can be removed easily after use.
CONSTITUTION: During use as an anchor, a fixing portion 1 has a wave-shaped spiral coil 4 in its core and the surrounding part is covered with a flexible cover film 8 for preventing the adhesion of mortar 11. Steel tension members 3 of an anchor are arranged around the cover film 8 and the coil contraction portion 6 are reduced in diameter by fasteners 9. Since the shape of the fixing portion 1 is maintained by the fasteners 9, the anchor exhibits a sufficient fixing effect. After use as an anchor, the coil straight-portion 7 is pulled to pull out the coil 4, and then the steel tension members 3 are applied with a tensile force to break the adhesion portion of the mortar 11 and to remove the steel tension members 3.
