Steel frame integrated member for concrete core tube structures and assembly method thereof

Abstract

The invention relates to a steel frame integrated member, in particular to a steel frame integrated member for concrete core tube structures and an assembly method thereof, and belongs to the field of steel structures. The steel frame integrated member comprises a core tube, a steel column component and steel beam components. The bottom of the steel column component is fixed to the core tube. Two lateral ends of an upper end of the steel column component are provided with the steel beam components fastened to the steel column component, respectively. The assembly method includes the steps of subjecting parts to setting out and blanking, perforating the parts, reinforcing a steel column, performing assembly and inspecting the member. The steel frame integrated member and the assembly method thereof have the advantages that the structure is compact, ductility of a steel-structure beam-column joint is improved, the ability of the joint to resist earthquakes and dissipate energy is enhanced, and overall seismic capacity of the structure is further improved.

Description

technical field [0001] The invention relates to a steel frame integrated component, in particular to a steel frame integrated component for a concrete core tube structure and an assembly method thereof, belonging to the field of steel structures. Background technique [0002] At present, the joint method between the steel concrete column (the inner steel pipe is steel pipe) and the steel concrete beam is as follows: the steel pipe in the steel pipe concrete column is provided with a ring plate at the upper flange of the steel beam, the steel beam flange in the steel beam is welded to the ring plate, and the steel bar in the steel beam Through section steel, partly bent around the steel pipe. The construction unit of this kind of joint form must open holes for the steel pipes to pass through the steel bars in the processing plant or on site. The opening of the steel pipe caused damage to the column section, and the construction period was long. [0003] In previous engineer...

Problems solved by technology

However, under the action of natural disasters such as earthquakes and hurricanes, the structure enters an elastic-plastic state or a plastic state. At this time, the interaction force between the square steel column and the steel beam is very large, and the traditional connection method is difficult to ensure that the square steel pipe The steel columns and steel beams work together, and once the connection between the square steel tube steel columns and the reinforced steel beams is
