Strapping method for epoxy-resin-coated column hoops of frame columns under corrosive environments

Abstract

The invention discloses a strapping method for epoxy-resin-coated column hoops of frame columns under corrosive environments. The corrosive environments include chemical corrosive environments, hot and humid corrosive environments and chloride permeation corrosive environments. The strapping method is characterized by including the following steps of a, strapping the epoxy-resin-coated column hoops of the frame columns; b, alternately arranging hook overlapping portions of the epoxy-resin-coated column hoops along column epoxy-resin-coated vertical ribs, and strapping the hook overlapping portions tightly; c, ensuring that the tip angles and the straight-portion lengths of the epoxy-resin-coated column hoops meet design regulations and requirements. The strapping method for the epoxy-resin-coated column hoops of the frame columns under the corrosive environments has the advantages that reinforcing bars are constructed scientifically and reasonably, completeness of epoxy resin coatingson the surfaces of the reinforcing bars is guaranteed, corrosion and rust resistance of the epoxy-resin-coated reinforcing bars is well developed through effective strapping measures for the reinforcing bars, and the problem of high breakage rate in construction of the epoxy-resin-coated reinforcing bars is solved.

Description

technical field [0001] The invention relates to a method for binding steel bars, in particular to a method for binding epoxy resin-coated column stirrups of frame columns in chemical corrosion environments, hot and humid corrosion environments, and chloride penetration corrosion environments. Background technique [0002] Steel bar corrosion in reinforced concrete is an important problem faced by civil engineering and marine engineering in chemical corrosion environment, hot and humid corrosion environment, and chloride penetration corrosion environment. Steel bar corrosion will cause catastrophic accidents in the project. Epoxy coated steel bars are an important solution to the corrosion of steel bars in concrete. Epoxy coating has the effect of anti-oxidation ion, chloride ion and water molecule penetration between steel bar and concrete, and the strong bonding force between coating and steel bar, so that the epoxy resin coated steel bar in concrete has excellent resistanc...
