In order to meet the construction quality and construction schedule requirements of the core tube of the super high-rise building structure, the application of the jacking formwork system has gradually become a trend. During the construction of the top formwork system, construction elevators are required as a means of vertical transportation. According to the relevant regulations, the stability of the construction elevator must be guaranteed through the wall-attached device. However, within the height range of the top form, the standard wall attachment device is no longer applicable, and the traditional treatment method is to continue to set the fixing device to attach the construction elevator to the top form. However, every time the top mold is lifted, the attachment device cannot slide up synchronously, so it must be loosened, and other equipment is used as a temporary support, which increases the process, is time-consuming and laborious, and restricts the construction speed, cost and safety. Progress, such as the following shortcomings and deficiencies:

1. Within the height range of the top mold, the construction elevator attachment device cannot rise synchronously with the top mold through sliding, and human intervention is required to increase the top mold jacking process.

2. When the top formwork system is jacking up, it is necessary to temporarily loosen the original attachment device, which increases the risk of the construction elevator overturning.

3. During the jacking process of the top mold system, other equipment needs to be used to increase temporary support, occupying resources and increasing costs.

4. The attachment device cannot be modularized or automated in a standard way. Repeated disassembly and assembly will cause large wear and tear on the components, increasing the unpredictability of the project.
