Concrete filled steel tube transfer joint structure and construction method thereof

Abstract

The invention discloses a concrete filled steel tube transfer joint structure and a construction method thereof. The concrete filled steel tube transfer joint structure comprises a strut, a batter post and a socket frame; the batter post is fixedly connected to the socket frame; the socket frame is fixedly arranged inside the strut and located at a top end of the strut; the socket frame comprises a vertical inner ribbed plate; the batter post is provided with a section including a cross section; a shape of the vertical rib ribbed plate corresponds to a shape of the cross section and a connecting ribbed plate extends out of the vertical inner ribbed plate; the connecting ribbed plate extending out is fixedly connected to an inner wall of the strut; the batter post is fixed on the vertical inner ribbed plate through the section. The concrete filled steel tube transfer joint structure is integrated with the advantages of a concrete-filled steel tube and a battery post transfer structure, and has the advantages of direct force transfer, high bearing capacity, small sectional dimension of the component, good utilization of building space, no need for support formwork, small field welding workload, guaranteed construction quality and the like. Two batter posts and a beam system form a triangular force transfer mode, and meanwhile, excellent side force resisting capability is realized.

Description

technical field [0001] The invention relates to a building transfer node structure and a construction method thereof, in particular to a steel pipe concrete transfer node structure and a construction method thereof. Background technique [0002] As the functions and forms of high-rise and super high-rise buildings continue to diversify, the application of transfer floors is becoming more and more extensive. The inclined column transfer structure has transfer members, which mainly bear the axial load, has the characteristics of short force transmission path and small cross-sectional size of the transfer members, which is beneficial to the use of architectural space, so it has a wide application prospect. In addition, because the transition member mainly bears axial load, it is suitable to adopt the CFST member. The size of steel pipe concrete members is smaller than that of traditional reinforced concrete members, and it saves formwork and does not need to bind steel bars. T...

AI Technical Summary

Problems solved by technology

The bearing capacity of reinforced concrete members is low. In order to meet the safety requirements, the cross-sectional size of the inclined column and the volume of the joints are large, which will reduce the use of space in the transfer floor building and inconvenience the passage of pipelines.

[0007] (2) Node construction is difficult

However, the upper and lower inner partitions are installed in the core area of ​​the joint, and the welding workload is relatively large. When the cross-sectional size of the pillar is small, the welding construction and concrete pouring are difficult, and the construction quality is difficult to guarantee
