Description

Technical Field

[0001] The invention belongs to the field of assembled steel structure construction, and in particular relates to an automatic rapid installation and correction method for steel columns. Background Art

[0002] In recent years, with the increasing popularity of the concept of green engineering and the vigorous promotion and application of prefabricated buildings across the country, steel structures, as a typical form of prefabricated structures, have also been increasingly used and promoted.

[0003] Compared with precast concrete components, steel structural components have considerable advantages in terms of self-weight, strength, and especially processing and manufacturing conditions and technology. Steel structural components are flexible to process, have high precision requirements, and are formed in a variety of ways. Components can be processed in the factory or on site. Component disassembly is relatively flexible, and assembly can be done by welding and bolting.

[0004] At present, the installation and correction of steel columns in prefabricated steel structures all use ear plates in combination with temporary fixing bolts and the installation of cables and wind ropes. This method will use a lot of existing site space in the construction of group columns because the installation of cables and wind ropes in multiple directions will cause difficulties in construction site layout and transportation. The multiple personnel deployment during the correction process also increases the labor cost of correction, while making the steel column correction efficiency low. The installation of cables and wind ropes everywhere will also cause certain safety hazards and increase the cost of accessories and materials. In addition, the method of temporarily fixing the upper and lower sections of steel columns using ear plates in combination with temporary fixing bolts will add ear plates and other similar connection structures during the component processing process. After the upper and lower sections of the columns are welded and connected, the ear plates will be cut off, which increases the cost of component production and causes a waste of resources. Summary of the invention

[0005] The present invention aims to invent an automated and rapid installation and correction method for steel columns, which eliminates the need for temporary connection ear plates and temporary fixing bolts used in welding and butting steel columns, replaces the guy ropes used in steel column correction, and reduces the investment in manpower and mechanical equipment during installation and correction, thereby achieving the purpose of optimizing the operation during steel column installation and correction, improving construction efficiency, and reducing processing and construction costs.
