[0002] Steel structure assembly is a complex and delicate process, involving multiple links and professional techniques. First, according to the design drawing, the steel material needs to be accurately measured and cut to ensure the size of each material is accurate. Then, through welding, bolt connection or riveting, etc., the cut steel parts are assembled one by one to form the basic frame of the steel structure. In this process, the welding quality and connection accuracy need to be strictly controlled to ensure the stability and safety of the entire structure. After assembly, necessary inspection and testing, such as weld flaw detection and size review, are required to verify the reliability and compliance of the steel structure with the design requirements. When the steel structure is assembled, in order to avoid displacement of the steel structure and affect the assembly accuracy of the steel structure, a clamp is often used to fix the steel structure. At the same time, when the steel structure is assembled, it needs to be moved slightly to adjust the position. Some larger steel structures are heavy, so it is laborious to move and adjust the position by manpower, which increases the workload of the workers and affects the assembly efficiency of the steel structure. Therefore, a clamp for steel structure assembly is needed to solve the above problems. SUMMARY
