[0002] In the fields of nuclear power and so on, the upper reinforcement module needs to be hoisted and then connected to the lower reinforcement module in response to the modularization requirements of reinforcement. At present, most nuclear power reinforcement modules are four-layer reinforcement structures, with the layout of transverse reinforcement + longitudinal reinforcement + transverse reinforcement + longitudinal reinforcement. They are tied with steel wire and then hoisted. However, due to the insufficient strength of the steel wire bundling, the upper reinforcement module is very easy to deform during the hoisting process. When connected with the lower reinforcement module, there will be different degrees of height difference between the upper and lower reinforcements, which exceeds the design range, making it difficult to mechanically connect the upper and lower reinforcements and requires adjustment.
