Prefabricated assembled steel-concrete composite beam connected by adopting high-strength bolt
The invention discloses a prefabricated assembled steel-concrete composite beam connected by adopting a high-strength bolt. The composite beam main comprises a steel beam, a prefabricated reinforced concrete slab and a shearing resistant bolt connection pair, wherein reasonable structural measures are reserved on the steel beam and the prefabricated concrete slab, and the shearing resistant bolt connection pair is adopted to connect the steel beam with the prefabricated concrete slab, so that compared with a situation that the beam-slab connection part is in rigid connection and the shear capacity is not substantially reduced, strong ductility and deformability can be obtained. When a prefabricated slab needs to be replaced, by detaching the nut of the shearing resistant bolt, the prefabricated slab is separated from the steel beam, so as to realize detaching and replacement of the prefabricated slab. All components adopted in the invention are assembled and connected on site, so that field welding work and template engineering can be reduced, the industrial assembly efficiency of buildings is improved, the function of detaching, separating and replacement of the beam-slab main body structure of the assembled composite structure can be achieved, and the novel architectural concept of capability of detachment and energy conservation and environment protection of building components can be embodied.
