ABSTRACT:
A method and an anchoring element for high strength solid wall anchoring in which a solid plastic plug is inserted in a hole in a solid wall of a porous material such as concrete. The invention provides a high strength compressive bonding between the plastic plug and the wall which simulates high strength chemical bonding. In order to effect the high strength compressive bonding, the plug is inserted into a hole in the wall having nominally the same dimension as the plug. A screw of substantially the same diameter as the plastic plug is inserted into the plug to provide the anchoring. The plastic of the plug is an extrudible material such as polypropylene, high density polyethylene and co-polymers, which is extruded against and into the solid wall of the hole by the rotary insertion of the screw. Continued rotation of the screw causes a very high compression of the plastic between adjacent threads of the screw and a thin, very highly compressed film, which substantially covers the threads. The extrusion and the highly compressed areas of plastic provide phenomenally high resistance to pull-out of the plug from the wall. The plastic plug further contains one or more hairline separations or cleavages which serve to guide the screw into a path in the center of the plug to maximize the extent of the circumferential extrusion.
