METHOD AND COMPOUNDS FOR ANCHORING OF FASTENING MEMBERS IN DRILLED HOLES Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: this relates to anchoring of screws, nails, bolts, etc. by means of double-component glues and metal shells. According to method, drilled holes are cleaned and degreased if needed and filled approximately in half or three quarters with mixture liable to compaction. Mixture is made up of highly wear-resistant fibres or chips of metals, polymers and/or ceramics with average length of particles less than half of hole diameter. Then, thickening agent is added if necessary and after that both components of glue are brought into hole simultaneously or one after another. Finally, remaining part of hole is filled with required amount of metal chips, fastening members are inserted into hole and secured if necessary. Low-molecular fungicide can be added to double-component glue for sanitation of part of base adjoining hole made of wood, stone or concrete. EFFECT: high efficiency. 9 cl
