[0002] In recent years, high-rise buildings have become one of the main models of urban buildings today. They are of great significance for saving limited resources and achieving reasonable space allocation. The core tube combined with the frame structure plays an important role in improving the structural and functional properties of high-rise buildings. This structural system has become the main structural type of many commercial buildings, and related technologies have also become mature, actively promoting the development trend of building diversification.
[0003] With the development of high-rise building industry, the application of climbing formwork and top formwork platform construction technology is becoming more and more common.
