This method is a reinforcement meth

This method is a reinforcement method with a section steel wrapped around the component. It can be divided into a wet-type steel reinforcement method and a dry-type steel reinforcement method. Generally used for the reinforcement of concrete columns, beams, roof trusses, especially large structures and large span structures.It is suitable for strengthening reinforced concrete beams, columns and brick columns, brick chimneys, etc., but the reinforcement process for round and curved members is relatively complicated. It has the advantages of convenient construction, less on-site workload, and can effectively improve the seismic performance of components. Its advantages are convenient construction, less on-site workload, and reliable stress. The disadvantage is that the amount of steel used is large, and the cost of reinforcement and maintenance is high. When chemical grouting is used to reinforce steel, the surface temperature of the section steel should not exceed sixty degrees; when the environment has corrosive media, there should be reliable protective measures.
