Enlarged cross-section reinforcemen

Enlarged cross-section reinforcement method; enlarged cross-section method is a reinforcement method that uses the same material as the original structure to increase the cross-sectional area of ​​the component, thereby improving the performance of the component. It can not only improve the bearing capacity of the reinforced member, increase its section rigidity, but also improve the ductility of the member through the treatment of the seismic zone.This method is widely used to reinforce general members such as beams, slabs, columns, and walls in concrete members, columns, roof truss, and brick walls and brick columns in steel structures.Its reinforcement effect is directly related to factors such as the stress level, material performance, construction process, joint surface treatment and whether to unload and reinforce the original structure during reinforcement. The utility model has the advantages of simple process and wide application area, and can be widely used for strengthening beams, columns, slabs, walls and other components in concrete structures. The disadvantage is that the workload of on-site wet work is large, the use space is reduced, and the structure's own weight is greatly increased.
