[0003] At present, the conventional practice for curved curtain walls is to use beams and columns of different sizes to splice and combine them into the keel structure required for the outer curved surface of the curtain wall, and then install the curved panel panels on the keel structure. This structure requires more keels with different sizes, which are difficult to achieve unified processing and the mold opening cost is high. At the same time, during on-site installation, they need to be installed one by one according to the actual curved surface requirements, and the installation efficiency is low. In areas with high wind pressure or frequent earthquakes, the stability and safety of conventional keel structures are also difficult to guarantee, so a new solution is needed to solve this problem.
