The invention discloses a steel-concrete composite beam connecting structure and a design calculation method. The connecting structure comprises prefabricated concrete floors, an H-shaped steel beam, a rear steel bar frame, rear through longitudinal bars and post-pouring concrete. A longitudinal through groove and a plurality of vertical through grooves are formed in the side surface of the connecting side of the prefabricated concrete floor, connecting steel bars extend out of the vertical through grooves, and hooks are formed at the ends of the connecting steel bars; the prefabricated concrete floors on the two sides are spliced on the upper flanges of the H-shaped steel beams; the rear steel bar frame is arranged in the middle of the vertical through grooves formed by butt joint of the floors on the two sides; the rear through longitudinal bars penetrate through the rear steel bar frame and the hooks at the ends of the connecting steel bars; and the post-pouring concrete is poured in the longitudinal through groove and the multiple vertical through grooves. The technical problems that a hogging moment area of a traditional steel-concrete composite beam is prone to cracking, low in construction efficiency and poor in durability are solved, and the steel-concrete composite beam connecting structure has the advantages of being reliable in performance, simple in structure, convenient to splice in an industrialized production site, high in construction efficiency and the like.
Description
technical field [0001] The invention relates to the technical field of building structure connection structures, in particular to a steel-concrete composite beam connection structure and a design calculation method. Background technique [0002] According to the relevant requirements of the national sustainable development strategy, green and industrialized construction has become the main trend of the development of my country's construction industry. Vigorously promoting prefabricated buildings and continuously improving the assembly rate of construction projects has gradually become the key development direction of my country's civil engineering field. The steel-concrete composite structure can make full use of the performance advantages of steel and concrete materials. It has the advantages of high bearing capacity, high rigidity, good seismic and dynamic performance, small component cross-sectional size, and quick and convenient construction. It has become an important s...
