[0002] With the state's increasing attention to the environment and the increasing improvement of life, people's desire for a better life is increasing. In public buildings, circular column structure is a relatively common structure. In the past construction, reinforcing steel hoop or steel wire is commonly used for reinforcing circular column formwork. In the reinforcing steel hoop reinforcing process, the reinforcing steel and the formwork contact surface are not matched, the reinforcing steel hoop is easy to be tripped off at the reinforcing position, causing the formwork to swell, slurry leakage, etc. Steel wire reinforcement is easy to cause formwork damage and is more troublesome to disassemble, and cannot be recycled.
[0003] The use of reinforcing steel hoop reinforcement has the problems of large material consumption, complicated reinforcement and installation, difficulty in carrying, inability to adjust when the member cross section changes, low turnover efficiency, etc. Steel wire reinforcement has the problems of instability and inability to recycle.

However, they are all customized according to the outer diameter of the concrete column formwork. If the construction of a variable-diameter concrete column is encountered, multiple steel belts of different lengths need to be customized to adapt to different concrete column formworks, which has poor adaptability and increases the use cost
