Method for reinforcing a building component

摘要

A method for reinforcing a part of a building comprises the step of adhesively bonding a textile to the surface of the part of a building by means of an adhesive. The invention relates further to such a reinforced part of a building and to the use of a textile in combination with an adhesive for reinforcing a part of a building, wherein the textile is adhesively bonded to the surface of the part of a building by means of an adhesive.

1. Method for reinforcing a part of a building, comprising the step of adhesively bonding a textile to the surface of the part of the building by means of an adhesive,
wherein the textile before the adhesive bonding has a ductility of ≧1.0, the adhesive in the cured state has a ductility of ≧1.5 and the part of a building after the adhesive bonding has a ductility of ≧2, wherein the ductility is in each case determined as the ratio of the value of the total elastic and plastic deformation to the value of the elastic deformation, and wherein the adhesive comprises an aqueous polyurethane dispersion comprising a polyurethane dispersed in water, wherein the polyurethane is the reaction product of the following components: A1) polyisocyanates, A2) polymeric polyols and/or polyamines having weight-average molar weights of from ≧400 g/mol to ≦8000 g/mol, A4) at least one compound selected from compounds which have at least one ionic or potentially ionic group, and A5) non-ionically hydrophilised compounds.
