Assembling type concrete-filled steel pipe combined column node area connection structure

Abstract

The invention relates to the field of architectural structure members and discloses an assembling type concrete-filled steel pipe combined column node area connection structure. The assembling type concrete-filled steel pipe combined column node area connection structure comprises a central square steel pipe, end square steel pipes, H-type steel beams, connecting plates and stiffening plates. The central square steel pipe and the end square steel pipes are connected through two parallel connecting plates. The H-type steel beams are perpendicularly fixed to the end square steel pipes. Two side edges of flange plates of the H-type steel beams and the inner and outer side faces of the end square steel pipes are in the same horizontal plane. The stiffening plates are fixedly arranged on the inner sides and the outer sides of the end square steel pipes. The two ends of the stiffening plates are fixedly connected with the connecting plates and the flange plates of the H-type steel beams respectively. According to the assembling type concrete-filled steel pipe combined column node area connection structure, anti-seismic requirements for strong columns and weak beams and strong nodes and weak members can be satisfied; structural integrity is good; structural rigidity is high; node stress is more reasonable; it is guaranteed each branch column can work cooperatively and bear the stress together; and the whole machining process is all completed in a factory, only installation is needed to be conducted on site, the construction period is shortened greatly, and the project cost is saved.

Description

technical field [0001] The invention relates to the field of building structural components, in particular to an assembled steel pipe concrete composite column node area connection structure. Background technique [0002] Concrete-filled steel tube composite columns are mainly used in multi-storey and small high-rise residences. Compared with the steel plate shear walls commonly used in high-rise steel structure residences, there are problems such as complex manufacturing procedures, difficult processing and installation, and poor controllability of the processing and manufacturing quality of joint areas. , which has the advantages of small cross-sectional size, flexible cross-sectional form, and equal width between columns and walls to avoid indoor convex corners caused by excessive column cross-sections, which improves the usable area of ​​the house, room layout and occupancy experience of the owners. [0003] The steel tube concrete composite column structure is connected...
