Attach steel plates to the exterior of concrete components to improve carrying capacity and meet normal use of reinforcement methods.The reinforcement method has the following advantages: the reinforced component is basically undamaged, can give full play to the role of the original component, the outer sticky steel thickness is small, the self-weight increase smaller after reinforcement, the shape of the reinforced component smaller change, the impact on the building function is very small, the construction process is simple.However, the reinforcement effect depends to a large extent on the adhesive process and operation level, in addition, there are few tests on the anti-power performance and anti-fatigue performance of the adhesive steel components, which affects the application of the adhesive steel reinforcement method.
