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.

At present, in the construction of super high-rise core tube structures, the top formwork system is mostly welded and bolted. In order to improve the versatility, convenience and economy of the top formwork system, a top formwork platform composed of Bailey frame assembly has been formed. However, the conventional Bailey frame can only be welded and bolted, which cannot meet the assembly requirements of the top mold platform.
