Necessary conditions for installation of steel structures

It is an indispensable part of the steel structure construction project. Its works can be found everywhere, in many factories, stadiums, high-rise buildings and other places. However, it is also very strict. So what are the working conditions for steel structure installation?

Compile the organization design of steel structure installation and construction. After approval, the steel structure installation procedure shall ensure the stability of the structure and not cause deformation. Obtain qualified materials of inspection, installation support or foundation acceptance of the supervision unit and the general project contract. Prior to installation of steel structures, the incoming components shall be inspected according to the component list. Check quality documents and design change documents; Site assembly of large factory-installed components shall be carried out according to the pre-assembly conformance record. The necessary technical data and pre-assembled layout of large components should be complete, and the following points should be paid attention to:

The components shall meet the design requirements and specifications. Major components should be rechecked. Components should be protected from coating damage during transportation and installation. Before installation, remove dust, snow, oil, dirt and other debris attached to the surface. Steel structural components shall be supplied in a complete set according to the installation procedures, and the site stacking site can meet the needs of site assembly and sequential installation. Roof truss shall be assembled in sections, worktables shall be ready for site assembly, and components shall be classified and stacked. The component with higher stiffness can be stacked horizontally with mat wood, and the roof frame should be erected, close to the column and tied firmly. Quality requirements for hole making, assembly, lamp connection, riveting, coating, etc. The placement of components on the construction site shall comply with relevant regulations. Check parts for damage or deformation during loading, unloading, transportation and stacking. Damaged and DEFORMED parts SHALL be CORRECTED or reworked, and damaged anticorROsive primers SHALL be reapplied and re-inspected and accepted. Check and record components for external geometry, holing, assembly, lamp connections and friction surfaces.
