[0002] In the assembly construction of bridge reinforcement projects, steel mesh is one of the important prefabricated steel component combinations. It is often processed in the construction site and then transported to the construction site for rapid assembly to improve the efficiency of the in-situ reinforcement construction of the project. The existing steel mesh is usually formed in the construction site as follows: first, the steel unit components required for the steel block are processed on the general steel equipment, and then the steel unit components are hoisted to the special steel mesh frame. Finally, the steel unit components are manually assembled into a steel mesh in the frame and tied or welded into shape. The formation of steel mesh requires tying or welding, especially welding, which requires high skills of industrial workers. Workers have problems such as difficulty in ensuring welding quality when working for a long time.
