Method of repairing joints of panel prefabricated concrete structure at spots of panel joints

摘要

A method of repairing joints panel prefabricated concrete structures at the joints neighboring obvodovýchdílcu a partial internal structure consisting in the drilling of at least one channel through nehožse into the joining injected filling material consisting in that first at joints check degree of pollution and / or after with the impurities and / or the moisture removed by the action of compressed air containing abrasive particles, whereupon místospoje filled filler and subsequently inside vpravív liquid state without pressure two-component polyurethane which is mixed in the inner space of the filler and allowed to vytvrdit.Výplnovou mass for making processes form a two-component polyurethane which one component (a) comprises at least one polyol having a molecular weight in the range from 190 to 6000, preferably from 200 to 2000 being particularly preferred molecular weight range from 400 to 800 and component (B ) which contains the polyisocyanate component, a component having at least two isocyanate groups per molecule, and which is supplemented by preferably one or more additional ingredients such as modifiers of the physical or cure properties of the adhesive system, for example amines, quartz, molecular sieves, speed controllers, curing accelerators and / or fillers, and additionally contains a plasticizer.
