[0002] Steel structure buildings are buildings that use construction steel to form a load-bearing structure. They are usually composed of beams, columns, trusses and other components made of steel and steel plates. Due to their simple construction, steel structure buildings are widely used in large factories, venues, super high-rise buildings and other fields.

[0003] In traditional steel structure buildings, steel box girders are one of the main horizontal structural components. Since steel structures often have large spans and are limited by transportation or installation conditions, box girders need to be manufactured in sections and then assembled on site. At present, when assembling box girders on site, two box girders are usually connected together by on-site welding. However, due to problems with welding quality and construction efficiency, this connection method has some defects, such as welding defects, welding deformation, and weld joint fatigue, which affects the construction speed and quality. Therefore, it is necessary to design and modify the box steel girders to effectively prevent the phenomenon of poor splicing effect. Utility Model Content
