Description

[0002] As people have higher requirements for the aesthetics of buildings, arcs are used more and more in buildings. The arcs are integrated into the appearance of buildings, giving people a round and soft feeling. Figure 4 As shown, some buildings feature double-layered, fan-shaped structures at the four corners of their facades. These structures consist of two layers of fan-shaped surfaces connected by tie beams. Traditional wooden formwork and steel pipe supports are commonly used for these double-layered concrete structures. This requires re-measuring and re-setting the vertical poles for each layer, a continuous cycle of formwork configuration and removal. Furthermore, the narrow interior space of the double-layered fan-shaped surfaces makes installation and reinforcement of the upper fan-shaped formwork extremely difficult. Currently, there is no reasonable solution to this problem. Utility Model Content

[0064] The eighth step is pouring concrete, and the specific pouring method is the existing technology.

[0065] Step 9: After the concrete structure strength meets the requirements, remove the formwork.

[0066] The tenth step is to install and pour the material for rotation when needed on the upper floor.
