Prestressed ribbed beam and slab combined structure system
A prestressed rib beam plate composite structure system comprises a steel pipe concrete column, a U-shaped composite steel main beam, a steel secondary frame beam and a double-beam plate composite floor slab, the steel pipe concrete column is composed of an outer steel pipe and inner pouring concrete, the U-shaped steel main beam comprises double webs, an upper flange, a bottom plate and concrete, the U-shaped steel main beam is connected with the steel pipe concrete column in a welded mode, and the steel secondary frame beam is connected with the steel pipe concrete column in a welded mode. The double-beam plate composite floor slab comprises a double-beam prefabricated plate and post-cast reinforced concrete, the two ends of the double-beam prefabricated plate are fixedly connected with the U-shaped steel main beam respectively, and the steel secondary frame beam is connected with the steel pipe concrete column in a welded mode and arranged in the direction parallel to the span direction of the double-beam prefabricated plate. The double-beam prefabricated slab, the U-shaped steel main beam and the steel secondary beam are poured into a whole through the post-poured reinforced concrete and the concrete in the U-shaped steel main beam. The double-beam plate and the secondary frame beam used in the large-span direction are variable cross-section beams, the beam height in the large-span direction is small, the floor height can be reduced, the main body of the double-beam plate combined structure system is mainly of a steel structure, the allowable deformation is large, and the column cross section can be reduced.
一种预应力肋梁板组合结构体系，包括钢管砼柱、U形组合钢主梁、钢次框梁和双梁板叠合楼板，所述钢管砼柱由外钢管和内灌砼组成，所述U形钢主梁包括双腹板、上翼缘、底板和砼，所述U形钢主梁于所述钢管砼柱焊接联结，所述双梁板叠合楼板包括双梁预制板和后浇钢筋砼，所述双梁预制板两端分别与所述U形钢主梁固定联结，所述钢次框梁与所述钢管砼柱焊接联结，且平行于所述双梁预制板跨度方向布置，所述双梁预制板、所述U形钢主梁、所述钢次梁通过所述后浇钢筋砼和所述U型钢主梁内的所述砼浇筑为一体。大跨方向用双梁板，次框梁为变截面梁，大跨方向梁高小，有利于降低层高，且双梁板组合结构体系主体以钢结构为主，容许变形大，可减小柱截面。
