Embodiment
[0034] This embodiment provides a splicing joint between a steel pipe concrete column and a reinforced concrete column, such as Figure 6 As shown, the splicing node includes a lower concrete-filled steel tube column 2 , an upper reinforced concrete column 3 and a splicing component 1 in the middle.
[0035] The splicing part 1 comprises a closed-loop channel steel. Such as Figure 1~3 As shown, the shape of the closed-loop channel steel is square and hollow, and the overall shape is back-shaped. It is formed by welding four pieces of channel steel 11 cut into trapezoidal shapes.
[0036] The upper and lower ends of the splicing part 1 are the surfaces of the flange plates 112 of the closed-loop channel steel, and the upper and lower flange plates 112 are provided with multiple sets of relative through holes 12, and the side surfaces of the splicing part 1 are the outer sides of the web 111 of the closed-loop channel steel.
[0037] Such as Figure 5 As shown, the steel pip...

The invention discloses a steel pipe concrete column and steel bar concrete column splicing joint and a construction method, and relates to the technical field of building structures. The splicing joint comprises a lower steel pipe concrete column, an upper steel bar concrete column and a middle splicing component. The splicing component is connected with the steel pipe concrete column and the steel bar concrete column and comprises a closed-loop steel channel. The upper end face and the lower end face of the splicing component are flange plate surfaces of the closed-loop steel channel. An upper flange plate and a lower flange plate are provided with a plurality of through holes. The steel pipe concrete column comprises a hollow steel pipe, and the steel pipe is welded to the lower end face of the splicing component. The steel bar concrete column comprises a plurality of steel bars, and each steel bar sequentially downwards penetrates through the through holes of the upper flange plateand the lower flange plate and stretches into the interior space of the steel pipe. The boundary dimension of the section of the steel pipe is equal to the boundary dimension of the upper end face and the lower end face of the splicing component. The splicing joint is firm in structure, load transmission between the steel bar concrete column and the steel pipe concrete column can be guaranteed, and meanwhile the joint is simple in structure and convenient to construct.
Description
technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a splicing node of a steel pipe concrete column and a reinforced concrete column and a construction method. Background technique [0002] Concrete-filled steel tube column is a new type of high-efficiency composite member developed in recent years. It can give full play to the material properties of steel and concrete, and has the advantages of high bearing capacity and good seismic performance. Therefore, concrete-filled steel tube column has been widely used in high-rise buildings. more and more widely applied. However, with the increase of the height of the steel tube concrete column in the building, the vertical load on the structure gradually decreases, and it is no longer necessary to continue to use the steel tube concrete column. Therefore, after reaching a certain height, the steel tube concrete column can be replaced with a reinforced concrete c...
