Prefabricated assembled type steel-concrete combined beam connected through bolt nails
The invention provides a prefabricated assembled type steel-concrete combined beam connected through studs. The prefabricated assembled type steel-concrete combined beam connected through studs comprises an H-shaped steel beam which is formed by welding steel sheets, and shear bolt nails are welded to the upper wing edge of the steel beam; the prefabricated assembled type steel-concrete combined beam further comprises a prefabricated reinforced concrete floor, and through holes corresponding to the steel beam in position are reserved in the floor. After the steel beam and the prefabricated reinforced concrete floor are hoisted and docked, non-shrinkage self-compacting high-intensity concrete filler is poured into the holes, and integrated connection between the steel steam and the reinforced concrete floor is achieved. Good adhesion between the non-shrinkage self-compacting high-intensity concrete filler and the bolt nails is achieved, the bolt nails can have good horizontal shear resistance and drawing force resistance, and meanwhile the whole structure has good ductility and anti-seismic property. According to the prefabricated assembled type steel-concrete combined beam connected through studs, all components are prefabricated in a factory, assembling and connection are conducted at a construction site, site wet operation is reduced, project quality is guaranteed, the construction cycle is shortened, the assembling efficiency of building industrialization is improved, and social and economic benefits are good.
