The principle of sticky steel reinforcement is to use steel glue to fix steel plates on the load-bearing structure of the building to form a common force to achieve the role of strengthening the building. Many friends will say that there is now advanced carbon fiber cloth reinforcement. Why is it necessary to use sticky steel for reinforcement, so is carbon fiber reinforcement suitable for all cases? Obviously not. So in what cases do you need to use sticky steel glue for reinforcement?
First of all, we must look at the change in deflection, which is related to the bending stiffness of the beam. The elastic modulus of the steel plate and carbon fiber cloth is relatively close, so the cross-sectional area determines the degree of increase in stiffness. We know that the cross-sectional area of carbon fiber cloth is much smaller than that of steel plates, so the use of sticky steel reinforcement technology to increase the beam stiffness is more suitable than carbon fiber cloth reinforcement technology.
Secondly, considering the impact of the secondary stress, the initial situation of the reinforcement of the building should be analyzed, and the carbon fiber cloth is relatively lagging due to its stress. If the building itself has been deformed, it is not suitable to use the carbon fiber cloth for reinforcement.
Finally, considering the problem that carbon fiber cloth cannot be stacked more, the thickness of carbon fiber cloth reinforcement construction should not be too thick, and the amount of carbon fiber cloth should not exceed 2 layers, and for wet-laid fabrics, it should not exceed 4 layers. If there are more than 4 layers, you can consider using bonded steel reinforcement instead.
Neither bonded steel reinforcement nor carbon fiber cloth reinforcement can strengthen the building's bearing capacity indefinitely, and the limit values are different in different situations. Therefore, when dealing with building reinforcement construction, we must conduct structural appraisal of the building, and select a higher-quality reinforcement plan according to the structure identified by the appraisal office.
