[0052] The concrete aluminum alloy formwork system refers to a complete structural system that includes the formwork for forming the newly poured concrete and the bracket that supports the formwork. The function of the formwork is to form the shape and geometric dimensions required for the concrete component, and the bracket is used to maintain the designed position of the formwork.

[0053] In the related art, aluminum alloy formwork or plastic formwork is usually used for the construction of cast-in-place concrete structural walls. In the internal corners between walls or between walls and buildings, aluminum alloy formwork or plastic formwork is usually fixed by means of a combination of C-groove connectors and steel pipe fasteners and other mounting parts. However, the internal corners are narrow and difficult to operate. In particular, there is a risk of slippage failure of the fasteners, which can easily cause the formwork joints at the internal corners to deform and the internal corners to be not square. Especially for plain concrete, problems such as slurry leakage and mold expansion are prone to occur, and workers are required to trim the internal corners, which is laborious and time-consuming, and affects the surface quality. Therefore, there is an urgent need for an aluminum alloy formwork system to improve the construction efficiency of multiple internal corners.
