Square steel pipe fabricated column-prefabricated superposed beam integrally-fabricated frame and construction method
The invention discloses a square steel pipe fabricated column-prefabricated superposed beam integrally-fabricated frame and a construction method. The frame comprises a square steel pipe with inner and outer ribs, a square steel pipe casing with connecting wing plates and a prefabricated superposed beam. The square steel pipe is formed by rolling once, a thin centrifugally-produced concrete protective wall is arranged inside the square steel pipe, and high-performance concrete wraps the square steel pipe, so that a square steel pipe fabricated column is formed. The square steel pipe casing with the connecting wing plates is used for vertical connection between one upper square steel pipe fabricated column and one lower square steel pipe fabricated column as well as connection between the prefabricated superposed beam and the square steel pipe fabricated column. Short I-beams are arranged at the ends of the prefabricated superposed beam, and the prefabricated superposed beam is connected with the connecting wing plates on the square steel pipe casing through high-strength bolts. An engineered cementitious composite or fiber reinforced cement composite is poured in beam-column joint connection areas. The concrete fabricated superposed beam is connected with prefabricated floor slabs as well as the prefabricated floor slabs are connected both through fiber reinforced composite plastic boards. A prefabricated house has the advantages of reasonable stress, convenience in construction, high joint ductility, good endurance and anti-seismic performance and the like.
