Description
Technical field
The present invention relates to a kind of method for binding reinforcing steel bars, specifically, be a kind of corrosive chemical environments, hot wet corrosion environment,
The epoxy coating column tie-bar binding method of chloride permeating corrosion environment Frame Column Under.
Background technique
Reinforcement corrosion in armored concrete is corrosive chemical environments, hot wet corrosion environment, chloride permeating corrosion environment
The major issue that regional civil engineering, ocean engineering face, reinforcement corrosion can cause the catastrophic failure of engineering.Epoxy resin applies
Layer reinforcing bar is the important method for solving reinforcement in concrete corrosion.Epoxy coating has antioxygen ion, chlorine between reinforcing bar and concrete
Strong binding force between ion and the effect and coating and reinforcing bar of hydrone infiltration, so that the epoxy resin in concrete applies
Layer reinforcing bar has splendid anticorrosive effect, and Epoxy Resin Coated Steel Bars additionally increase compared with naked reinforcing bar because of epoxy coating
Expense, service life 20 years for only accounting for the part of engineering total cost very little, but thus can extending reinforcing bar or more.In corrosive environment
Reinforced concrete structure in using epoxy-coated reinforcement generate economic benefit and social benefit be very huge.But from ring
The requirement of shelter of oxygen reinforcing bar, construction property etc. analysis, if not taking scientific and reasonable construction technology accordingly and special arranging
The defects of applying, and leading to damaged epoxy coating, imperfect, hole, the reinforcing bar of armored concrete still can in corrosive environment
Corrosion, and reinforcing bar of the corrosion diffusion of part often than no epoxy coating is also fast, so that being applied using epoxy resin
The effect of layer reinforcing bar, has a greatly reduced quality, and economic benefit, structure safety etc. cannot be effectively ensured.
Chinese patent CN104559683A discloses a kind of moisture-proof for reinforced concrete structure on April 29th, 2015
