Prefabrication of steel components
According to the installation sequence and process requirements in the steel platform for the prefabrication and assembly of steel components, to ensure the quality of welding production.
Steel stitching flange plate splicing joints and web splicing joints of the spacing should be greater than 200 mm. Flange plate splicing length should not be less than 2 times the width; web stitching width should not be less than 300 mm, the length should not be less than 600 mm.
In order to facilitate welding, to ensure the quality of welding, as far as possible the columns, beams on the stiffener plate, connecting plate, plate, beam (beam) and so on the ground steel platform according to the size of the construction group for welding.
In addition to the construction drawings and specifications required for the production of steel components in the steel platform, but also should consider the on-site installation of the process and installation size changes.
