[0002] Elevator shaft climbing formwork refers to the basic frame used to support the lifting mechanism in the elevator shaft. In the construction of high-rise buildings, tower cranes are usually used to unload building materials within the frame. In order to reduce the load on the tower crane, a construction hoist can be installed through an independent elevator shaft climbing formwork to transport equipment such as formwork and supports. Therefore, elevator shaft climbing formwork is becoming more and more common in high-rise building construction.

[0003] At present, the elevator shaft climbing formwork is mainly composed of supporting platforms, columns, aluminum frame formworks, fixtures, positioning boxes and other structures. The supporting platform relies on four supporting claws to obtain support points with the help of concrete walls. During the initial construction, four reserved holes of appropriate sizes need to be reserved on the inner wall of the elevator shaft. First, the overall assembly is carried out. After the concrete is poured, the large formwork is retracted to the minimum position by relying on the four corners of the quickly retractable corner formwork to complete the overall demoulding. The cylinder formwork is gently lifted as a whole using a tower crane, and the entire cylinder formwork is lifted to the next construction layer for continued construction. Although this structure has the advantage of modularization, the overall construction structure is relatively complex and the amount of work is large. Summary of the invention
