[0002] In the renovation and structural reinforcement of old buildings, there are various construction methods for renovating existing non-penetrating secondary beam load-bearing brick walls. There are two commonly used construction methods: one construction method is to directly dismantle the secondary beam and the entire load-bearing brick wall under the original structural beam, and then construct reinforced concrete columns under the secondary beam. This construction method has a high construction safety risk and may cause the original structural beam to break or the building to collapse; the other construction method is to support the existing non-penetrating secondary beam load-bearing brick wall that needs to be renovated and then reinforce it. The support needs to be supported from the foundation to the top floor and from bottom to top, and then the load-bearing brick wall is dismantled from the top floor to the foundation to unload the load, and then new reinforced concrete columns are constructed from the foundation to the top floor. The entire renovation construction process will cause disturbance to the original structure, with a high construction safety risk and slow construction progress. It requires a large amount of manpower, materials, and machinery, which greatly increases the construction cost. Summary of the invention

When reinforced concrete columns 1 and 2 reach the design strength and bear the upper load, the reinforced concrete column 3 is positioned and laid out, and the load-bearing brick wall within the range of the reinforced concrete column 3 is removed; c. Fabricate and install the longitudinal reinforcement and stirrup 2 of reinforced concrete column 3, connect stirrup 2 with reinforced concrete column 1 and reinforced concrete column 2 by planting reinforcement, and connect the longitudinal reinforcement of reinforced concrete column 3 with the original structural beam by planting reinforcement; install the template of reinforced concrete column 3 and pour concrete; d.
