Specific embodiment
Embodiment one:
Please refer to Fig. 1 to Fig. 4, a kind of assembly concrete-filled steel tube coupled column, including concrete filled steel tube prefabricated component 1 and spiral shell
Bar 2.
In the present embodiment, the concrete filled steel tube prefabricated component 1 is enclosed by two steel core concrete columns 11 splices integral, tool
In body structure, the steel core concrete column 11 includes the rectangular steel plates 111 of outer wall and the curved plate 112 of inner wall, encloses splicing
Afterwards, the curved plate 112 constitutes the inner wall of the concrete filled steel tube prefabricated component, and the rectangular steel plates 111 constitute the steel pipe
The outer wall of precast concrete.As shown in Figure 2 and Figure 4, the curved plate of two steel core concrete columns 11 all has two points
One of circumference, after enclosing splicing, the concrete filled steel tube coupled column inner wall section is circle, outside the concrete filled steel tube coupled column
Wall section is square.
