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 notches in such a way as to erect and expand the notches. CONSTITUTION:The peripheral wall of a cylindrical anchor rod A is provided alternately with ?-shaped notches 2 whose basal portions are turned toward the tip of the rod A and ?-shaped notches 3 whose basal portions are tuned toward the rear end of the rod A. The rod A is driven into a banking 9 through the hole 8 of the retaining wall 7, and then an expandible material 10 is injected into the rear end opening of the rod A, whereupon the expandible material 10 expands and solidifies to erect ?-shaped tongue pieces 4 and 5 and also to expand the pe ripheral portions of the notches 2 and 3. Thus, a drawing resistance is given to the rod A by the tongue piece 5, a bearing force is given by the tongue piece 4, and a frictional force is given by the expanded portion 11.
