ABSTRACT:
An anchoring arrangement kit includes a drilling tool adapted to drill a generally cylindrical anchoring hole in a support structure. The kit further includes a support arrangement which supports the drill for rocking or orbiting motion to thereby enlarge the bottom region of the cylindrical hole, the arrangement including an abutment member which is stationary, and a cover member which rotates with the drilling tool during the undercutting operation, these members having complementary concave and convex contact surfaces for the rocking or orbiting motion of the drilling tool. The kit further includes a plurality of anchoring elements each having an anchoring member and a cap member surrounding the trailing end portion of the anchoring member so as to support the anchoring element at an open end of the hole with a clearance between the anchoring member and the surface bounding the hole. The kit further comprises an arrangement for introducing hardenable material into the clearance through an opening in the leading end of the anchoring member, which includes an injection device of the cylinder-and-piston type, and a shielding sleeve to guide the hardenable material from the injection device toward the opening and into the clearance. Finally, the kit includes a stirrer for mixing the hardenable material which stirrer has an entraining portion which has a receiving passage adapted to at least partly accommodate the drill bit of the drilling tool.
