Process and agent for anchoring securing elements in drill holes

Abstract

The process for anchoring securing elements in drill holes, particularly screws, nails, anchors, clamp irons, and bolts, by using two-component adhesives and metal additives, is such that a) the drill holes optionally rebored, cleaned and degreased in advance are filled up to from half to three quarters with a compressible mixture of highly wear-resistant fibers or chips made of metals, polymers and/or ceramics with an average length smaller than half the drill hole diameter, subsequently, a blocker is optionally added, then both adhesive components are introduced successively or simultaneously, and then the residual portion of the required amount of fibers or chips is filled in, or b) a kneadable mixture is prepared from a compressible mixture of highly wear-resistant fibers or chips with an average length smaller than half the drill hole diameter and both adhesive components, and the mass is forced into the drill holes, and subsequently, the securing elements are inserted and optionally secured. A low molecular weight fungicide may be added to the two-component adhesive to renovate the part of the support adjacent to the drill hole, which support is made of wood, brickwork or concrete.
