Background technique

Currently in the period of high-speed development of high-rise buildings, taller and taller buildings continue to emerge, and the application of top formwork systems in the construction of super high-rise concrete structures is becoming more and more popular. The components used in the top formwork system are all steel structures, which are costly and have a low reuse rate. In order to improve the versatility, convenience, light weight and standardization of the steel structure components of the top formwork system, the top formwork similar to the Bailey frame is now generally used. model system. However, the existing steel structure trusses of the top formwork platform are welded with I-beams or other shaped steels with reference to the structure form (stressed form) of the Bailey frame. The steel structure trusses of the top formwork in this form of force need to be customized and processed in the factory , The design and processing cycle is long. Therefore, the use of standard Bailey frame (actually 200 type) is convenient for procurement, turnover and use, which can greatly reduce the use cost of the top formwork system truss, and shorten the design cycle, production cycle and installation cycle. However, the existing topform truss support column connection device cannot be connected with the standard finished Bailey frame, and can only be connected with a special steel structure truss (or a Bailey frame structure made of section steel).
