Description

Technical Field

[0002] During the design and construction of reinforced concrete structures in construction projects, in order to eliminate problems such as structural cracking caused by shrinkage and deformation during the hardening process of concrete, expansion joints and post-poured concrete belts are set at certain lengths in the reinforced concrete structures. Pre-embedded steel bars are often required at the joints to ensure the integrity of the concrete structure. The time that the pre-embedded steel bars in the expansion joints are exposed to the air is determined according to the deformation requirements of the structural concrete and the construction process. It is generally 30 to 90 days, and some are even longer, with an interval of more than one year. These exposed steel bars will quickly rust in the air, and as time goes by, they will rust, weakening the cross-section of the steel bars. As a result, after the concrete construction at the joints, the overall structure will form a weak link at the joints, and even cause structural damage accidents.
