Prepare the organization design of the steel structure installation and construction. Implemented and implemented after approval, steel structure installation procedures must ensure the stability of the structure and not cause permanent deformation.
Obtain qualified data after the inspection by the supervision unit, the general contractor of the project, the installation of the support or the basic acceptance.
Before installing the steel structure, check the incoming components according to the component list. Check the quality certificate and design change documents; when large-scale components installed at the factory are assembled on-site, they should be based on the pre-assembly qualification records. The technical data necessary for component delivery and the pre-assembly layout drawings of large components should be available. point.
① The components shall meet the design requirements and specifications. The main components (pillars, crane beams, roof trusses, etc.) should be re-inspected.

② The components shall be protected from coating damage during transportation and installation.

③ Remove dust, ice, snow, oil, and dirt from the surface before installing the steel structure.

Steel structure components should be supplied in complete sets according to the installation procedures. The site stacking site can meet the needs of on-site assembly and sequential installation. The stiffer components can be stacked horizontally, and the roof truss should be placed upright, close to the column, and tied tightly.
The quality requirements of the components for making holes, assembling, lighting and riveting, and coating on the construction site shall comply with relevant regulations.
Check whether the components are damaged or deformed during loading, unloading, transportation, and stacking. Damaged and deformed components shall be corrected or reprocessed. The damaged anticorrosive primer shall be reapplied and re-inspected for acceptance.
Record and record the geometrical dimensions of the component, holes, assembly, light connection, friction surface, etc.
