According to the installation sequence and process requirements, the steel components are prefabricated and assembled on the steel platform to ensure the quality of welding production.
The spacing between the flange plate splicing joint and the web splicing joint of the profile steel should be greater than 200㎜. Flange plate splicing length should not be less than 2 times the plate width; The width of the web splicing should not be less than 300㎜, the length should not be less than 600㎜.
In order to facilitate welding and ensure welding quality, try to pair the reinforcement plates, connecting plates, backing plates, lifting beams (beams) on the ground steel platform according to the size of the construction drawing.
In addition to the production and assembly of the steel components prefabricated on the steel platform according to the construction drawings and specifications, the changes in the manufacturability and installation size of the on-site installation should also be considered.
