Abstract

The invention discloses a concrete filled steel tubular column, H-shaped steel beam, steel support and pi type connecting piece combined center column bottom joint and a making method. The joint mainly comprises a light square steel tube recycled concrete column, H-shaped steel beams, a pi type connecting piece, web connecting plates, high-strength bolts, steel supports, I-shaped bench binding steel bars, slab column binding steel bars and a prefabricated recycled concrete floor. Compared with the prior art, the joint is simple in structure and convenient to construct, and has a clear force transferring route and two seismic fortification lines. The novel structures such as the pi type connecting piece, the bench binding steel bars and the slab column binding steel bars are creatively proposed, and integrality of slab-column-joint domain is enhanced; bending resistance, pressure resistance and stability of the joint are effectively improved; reliability of the steel support and the pitype joint connecting structure is further ensured; and the joint is firm in beam-column-support-floor connection, high in integrality and excellent in seismic performance and the key technological support is provided for engineering design of a prefabricated green housing light steel combined structure.

Description

technical field [0001] The invention relates to a joint at the bottom of a central column of a combined type of concrete filled steel pipe column-H-shaped steel beam-steel support-π-shaped connector and a method thereof, belonging to the technical field of structural engineering. Background technique [0002] It has become an inevitable trend to realize the development of housing industrialization based on industrialization. The development of housing industrialization technology is the main means to realize the wide application of prefabricated buildings and achieve the development goals of urban green buildings. [0003] The prefabricated steel structure has the advantages of light weight, high strength, high production efficiency, and high level of assembly. It is an ideal structural system for the industrialization of village and town housing. The prefabricated light steel residential system has high assembly efficiency, low steel consumption, and low construction cost. ...
