Assembly type circular steel pipe column joint connecting device and assembly method

Abstract

The invention discloses an assembly type circular steel pipe column joint connecting device and an assembly method. The assembly type circular steel pipe column joint connecting device comprises a steel pipe column, connecting pieces and steel beams, a plurality of steel beams are arranged on the outer side of the steel pipe column in an annular array mode, the steel beams and the steel pipe column are connected through the connecting pieces, and a plurality of outer ribs are arranged on the lower portion of the steel pipe column in the annular array mode; the connecting pieces are correspondingly installed at the tops of the outer ribs, each connecting piece comprises a steel body, a plurality of clamping grooves are formed in each steel body in the annular array mode, and steel plates are connected into the clamping grooves and connected with the steel beams. According to the assembly type circular steel pipe column joint connecting device and the assembly method, the problem that welding between an existing circular steel pipe column and a profile steel beam is poor can be solved, and the space occupancy rate is small; the rigidity and the bearing capacity of a joint are improved to a great extent by overlapping and sleeving the connecting pieces such as annular thin steel plates, and meanwhile, the joint also has better integrity and stability; the assembly type circular steel pipe column joint connecting device has more mobility in a bolt penetrating hole fixing mode, connection between materials is reinforced, and the assembly type circular steel pipe column joint connecting device further has the advantages of being convenient to mount and dismount, large in application range and the like.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to an assembled circular steel pipe column node connection device and an assembly method. Background technique [0002] The prefabricated steel structure connection node device meets the development needs of construction industrialization, and its advantages such as easy installation and disassembly, and wide application range are more and more popular among people, and it is in line with the concept of green buildings. [0003] At present, most of the beam-column joints of fabricated steel structures are connections between square columns and steel beams. For circular steel pipe columns, less is involved. The effect of direct welding between existing circular steel pipe columns and steel beams is compared. Poor, and the way of node connection is too simple, resulting in the structure does not have strong node stiffness and bearing capacity. In the traditional fully ...
