Abstract

The invention relates to a connection joint between a prefabricated reinforced concrete superposed beam and a steel pipe column and a construction method thereof, and belongs to the field of buildingstructures. The joint is composed of a prefabricated steel pipe column, the prefabricated reinforced concrete superposed beam, a U-shaped steel sleeve, a connecting region and superposed board cast-in-place concrete; the prefabricated steel pipe column comprises the steel pipe column and a reserved H-shaped steel end head welded to the outer wall of the steel pipe column; the prefabricated reinforced concrete superposed beam comprises an upper load-bearing bar, a lower load-bearing bar, stirrups, a T-shaped connecting piece and precast concrete, wherein the T-shaped connecting piece is composed of a flange steel plate, a web steel plate and toggle pins welded to a web; the U-shaped steel sleeve comprises a U-shaped steel groove turning outward and connecting steel bars.

Description

technical field [0001] The invention relates to a connection node between a prefabricated reinforced concrete composite beam and a steel pipe column, belonging to the field of building structures. Background technique [0002] The steel pipe column is a vertical load-bearing member of a composite structure formed by pouring concrete into the steel pipe. It has high bearing capacity, good ductility, and convenient construction. It has been widely used in engineering. At present, the reinforced concrete beams connected with steel pipe columns are mostly cast-in-place construction, and the construction of the joints is cumbersome, and the workload on site is huge, which cannot meet the development needs of prefabricated buildings. Therefore, with the rapid development of prefabricated buildings, it is urgent to realize prefabrication Effective connection of reinforced concrete beams to steel pipe columns. Contents of the invention [0003] The object of the present invention...
