Fastening system for connecting plates to concrete - uses projecting fibres which are embedded into liquid concrete

摘要

The arrangement is used for fastening of components such as plates and sheets to concrete. The plates are anchored by a large number of projections on the plate underside. The anchoring elements are embedded into concrete while the latter is still liquid. The connecting components ensure high anchoring strength with low penetration depth and these can be used for panels of very large area. The density of the anchoring projections can be plastics mono-filaments held on a fabric and these filaments can be looped and orientated at random. The thickness of these projections varies between 0.1-1.5 mms and the length of these projections varies between 2-10 mms.
