PURPOSE:To regulate the head of an anchor in conformity with the conditions of construction site by a method in which a hole for tension member and a coupler are provided for the anchor plate, and an adjust plate with a hole for tension member and a clamp metal are also provided to the plate. CONSTITUTION:A tension member hole 21 and an injection hole 12 are drilled in an anchor plate 1. A tension member hole 21 is also drilled in the center of an adjust plate 2, whose one side is of a tapered groove pitch 23. The adjust plate 2 is lapped on the plate 1 and coupled with a coupler 13, and a tension member is passed through the center of a tube 71 and regulated to keep it almost vertical. The tension member can thus be tensed at the center of the anchor hole and the tube 71, and its angle can be easily adjusted without the needs to slide the adjusting plates. |
