VERFAHREN UND MITTEL ZUM VERANKERN VON SCHRAUBEN IN BOHRLOECHERN

摘要

A process for anchoring fastening elements, in particular screws, nails, anchors, clamps and bolts, in boreholes using two-component adhesives and metal inlays comprises the following steps: a) The boreholes, previously drilled, cleaned and degreased if necessary, are approximately one-half to three-quarters filled with a compressible mixture composed of highly wear-resistant metalol, polymer and/or ceramic fibres or chips whose average lengths are less than half the diameter of the borehole; a blocker may then be added if necessary; the two components of the adhesive are introcuced consecutively or simultaneously and the remainder of the necessary quantity of metal chips is then inserted. Or b) a material is prepared from a compressible mixture composed of highly wear-resistant fibres or chips whose average lengths are less than half the borehole diameter and the two components of the adhesive; this material is then pressed into the borehole. The fastening elements are then inserted and secured if necessary. A low-molecular fungicide may be added to the two-component adhesive to decontaminate the portion of the wooden, masonry or concrete backing surrounding the borehole.
