Prefabrication of steel components
The prefabrication and assembly of steel components on the steel platform according to the installation sequence and process requirements shall ensure the quality of the welding.
The spacing between the splicing seam of the splicing flange plate of the section steel and the splicing seam of the web shall be greater than 200 mm. The length of the flange plate splicing shall not be less than 2 times the width of the plate; the splicing width of the web shall not be less than 300 mm and the length shall not be less than 600 mm.
In order to facilitate the welding and ensure the welding quality, the reinforcing ribs, connecting plates, backing plates and picking beams (beams) on the columns and beams should be grouped and welded on the ground steel platform according to the construction drawing size.
In addition to the construction drawings and specifications required for the steel components prefabricated on the steel platform, the processability and installation dimensions of the on-site installation should also be considered.
