Abstract

PURPOSE:To raise the drawing resistance and frictional force of an anchor by a method in which an anchor whose periphery is provided with plural notches and openings is driven into banking, etc., and an expandible agent is injected into the upper end opening of the anchor to expand the peripheral portions of the notches. CONSTITUTION:An anchor A with a driving head 5 is driven into a banking 8 through a hole 7, and an expandible agent 9 is injected into the upper end opening of the anchor A until it reaches a position where notches 2 and 3 are present. Whereupon, the expandible agent 9 expands and hardens and ?-shaped tongue pieces 4 are erected by the expanding pressure of the expandible agent 9 to give a drawing resistance to the anchor A and also the peripheral portion of the cylinder 1 is expanded as the notch 3 expands to give a frictional force to the anchor A. After the end of the expansion, a closing metal is attached to the upper end opening of the anchor A projected from a retaining wall 6, and a tension is also given to the anchor A by a clamping means, e.g., nuts, etc.
