Our workers assemble steel beam with high strength bolt for the steel structure workshop.
Limited to transportation conditions, beams are made into sections in factories, and then joined into a whole at the site, which is called site joining. Because of the insufficient size of steel, the splicing of each component of the beam in the manufacturing plant is called factory splicing. At the joint, the strength of the beam should not be weakened and the continuity of deformation should be ensured. The joint of flange plate and web plate should be dispersed at different sections in the factory splicing of composite beams. In order to facilitate transportation, the joints of flange plate and web plate in site splicing can be set on the same section, but should be located in the less stressed part. Generally, groove butt weld joint is used in splicing method, which can save labor and material. But for heavy beam splicing in site, splicing plate high strength bolt connection can also be used to improve splicing quality and dynamic performance of beam.
