Steel beam inserted type steel-concrete combined section construction of composite beam
The invention discloses a steel beam inserted type steel-concrete combined section construction of a composite beam. The construction comprises a concrete beam-composite beam connecting structure connected between a concrete beam and the composite beam, and the composite beam comprises multiple steel beams and concrete bridge deck slabs. Each steel beam is a steel plate beam and comprises an upper flange plate, a lower flange plate and a web plate. The concrete beam-composite beam connecting structure comprises a front bearing plate, multiple rear bearing plates, multiple upper transverse penetrating steel bars, multiple lower transverse penetrating steel bars and multiple combined shearing resistant connecting structures located on the joint of the concrete beam and the composite beam. Each combined shearing resistant connecting structure comprises two upper rigid transition stiffening ribs, two lower rigid transition stiffening ribs, two upper longitudinal stiffening ribs and two lower longitudinal stiffening ribs. Shear nails are arranged on the sections, inserted into the concrete beam, of the upper flange plates and the lower flange plates. The steel beam inserted type steel-concrete combined section construction of the composite beam is simple in structure, reasonable in design, easy and convenient to construct and good in using effect, the connecting effect for constructing and forming steel-concrete joint parts is good, and stress is reasonable.
