[0002] In the middle of the outer side of the beam at some high-rise buildings, a double waistline of concrete pouring is designed to increase the beauty of the pouring object; these double waistlines are cast by setting up concrete wooden formwork. The erection of double waistline concrete formwork is time-consuming and labor-intensive, and there is a defect of large material loss. In particular, the upper waistline wooden formwork is supported on the lower waistline wooden formwork, which can easily lead to uneven force on the lower waistline wooden formwork. After pouring concrete, it is easy to cause leakage and waistline deformation, which cannot meet the design requirements. How to scientifically and reasonably set up the double waistline formwork system has become a technical problem that needs to be solved on site. . Summary of the invention
