The steel structure manufacturer is not only responsible for the design and production of various accessories of steel structure, but also for the overall installation of steel structure. Usually, before the construction of steel structure buildings, it is necessary to carry out convenient measurement and pre installation demonstration to ensure that there is no problem in the construction process. Generally, the key points of steel structure installation mainly include the following:
1. The prefabrication and assembly of steel members shall be carried out on the steel platform according to the installation sequence and process requirements to ensure the welding quality.
2. The distance between the splicing joint of flange plate and web of section steel shall be greater than 200mm. The splicing length of flange plate shall not be less than twice the plate width; the splicing width of web plate shall not be less than 300 mm, and the length shall not be less than 600 mm.
3. In order to facilitate the welding and ensure the welding quality, the stiffener plate, connecting plate, base plate and cantilever beam (beam) on the column and beam shall be assembled and welded on the ground steel platform according to the construction drawing size.
4. The prefabricated steel members on the steel platform shall not only be fabricated and assembled according to the construction drawings and specifications, but also take into account the changes of on-site installation process and installation size.
5. After installation, measure and test all aspects to ensure safety.
