Cold-formed thin-walled ribbed U-shaped steel-encased concrete laminated slab composite beam
The invention discloses a cold-formed thin-walled ribbed U-shaped steel-encased concrete laminated slab composite beam, and belongs to a composite beam, for solving the problems that lots of formworks are needed, the construction period is long, and the production is difficult to realize industrialization in cast-in-place reinforced concrete beams and slabs. The cold-formed thin-walled ribbed U-shaped steel-encased concrete laminated slab composite beam comprises a cold-formed thin-walled ribbed U-shaped steel beam on a lower part, a precast concrete slab, a continuous longitudinal reinforcement cage, a broken-line type tie bar and concrete, wherein the cold-formed thin-walled ribbed U-shaped steel beam is provided with a bottom plate, two web plates and two internally-rolled flange plates, and exhaust holes are designed in each flange plate; and a concrete precast bottom plate is arranged on the upper flange of the ribbed U-shaped steel beam, and the concrete is poured on the surface layer of the concrete precast bottom plate, in strip-shaped through holes in end parts, and in the ribbed U-shaped steel beam. The cold-formed thin-walled ribbed U-shaped steel-encased concrete laminated slab composite beam disclosed by the invention is simple in structure, good in fire-resistant performance and overall stability, high in combination action, convenient and fast in construction, capable of realizing industrialized production, remarkable in economic benefits, and capable of being used in floor structures of civil engineering buildings.
