Prestress loading system for temporary support construction

The utility model provides a prestress loading system for temporary support construction, which comprises an existing building, an assembly surface formed by the existing building and a temporary support, and the temporary support is fixed on the assembly surface of the existing building through a fixing piece to form a fixed structure. The prestress loading assembly is located on the temporary support, and a supporting face is formed on the prestress loading assembly; and the force application assembly is located on the supporting face, the force application assembly applies force in the direction of the existing building, and the force is transmitted to the temporary support through the prestress loading assembly, so that the temporary support is subjected to prestress in the direction of the existing building. And through the force application assembly, prestress abutting against the prestress is generated, and generation of bending moment is avoided. 本实用新型提供了临时支架施工用预应力加载系统，包括，既有建筑，所述既有建筑形成装配面，临时支架，所述临时支架通
