Painting Construction Method For Surface Repair And Reinforcement Of Bridge Structures

摘要

The present invention relates to a painting construction method for surface repair and reinforcement of a bridge structure, and more specifically, the present invention, a painting construction method for surface repair and reinforcement of a bridge structure, prevents dust scattering generated when constructing a place where the repair and reinforcement construction method is to be performed, and A maintenance step of installing a dust blocking and protective film to block dust; A surface cleaning step of removing the paint layer with a damaged film through chemical surface treatment or mechanical treatment and cleaning the surface of the removed structure by high-pressure washing with water or wiping with a dry cloth and then cleaning with an alcohol-based solvent or enamel thinner; forming an undercoat layer with an epoxy-based paint, wherein the undercoat layer is coated on the surface of the structure from which the existing paint has been removed, and the coating thickness is performed to a height corresponding to the height of the existing paint layer forming step; Forming an intermediate layer with an epoxy-based paint; and a topcoat layer forming step of forming a topcoat layer with a water-soluble fluororesin paint.
