Abstract

PURPOSE:To obtain a high drawing resistance, a high bearing force, and a high frictional force by a method in which an expandible material is injected into a cylindrical anchor rod whose peripheral wall is provided with ?-shaped and linear notches in such a way as to erect and expand the notches. CONSTITUTION:The peripheral wall of a cylindrical anchor rod A is provided with ?-shaped notches 21 whose basal portions are turned toward the rear end of the rod A, ?-shaped notches 31 whose basal portions are turned toward the tip of the rod A, and linear notches 4 extending along the longitudinal direction of the rod A. The rod A is driven into a banking 8 through the hole 7 of a retaining wall 6, and then an expandible material 9 is injected into the rear end opening of the rod A, whereupon the expandible material 9 expands and solidifies to erect the ?-shaped tongue pieces 22 and 32 to form an expanded portion 10. Thus, a drawing resistance and a bearing force are given to the rod A by the erected tongue pieces 22 and 23, and a frictional force is also given to the rod A by the expanded portion 10.
