[0002] The concrete-filled steel tubular column combines the tensile strength of the steel pipe and the compressive strength of the concrete, and is a high-efficiency composite structure; the concrete-filled steel tubular column can not only improve the bearing capacity of the column, but also enhance the stability and durability of the structure.

[0003] With the increasing demand for sustainable building materials, concrete-filled steel tubes, as a recyclable material, conform to the concept of green buildings. However, most of the existing concrete-filled steel tubular columns adopt an integral structure, and during construction, processes such as installing and supporting formwork, curing, and removing formwork are required. The process is cumbersome, the construction efficiency is low, and a large amount of construction waste will be generated during construction, which is likely to cause pollution to the surrounding environment.

[0004] In addition, the existing assembled concrete-filled steel tubular columns can reduce the construction steps and improve the construction efficiency, but they cannot be combined and assembled according to the needs of the construction site. The existing assembled concrete-filled steel tubular columns need to prefabricate fittings with different specifications according to the needs of the construction site to meet the requirements of the construction site, which will increase the assembly difficulty of the assembled concrete-filled steel tubular columns and affect the assembly efficiency of the assembled concrete-filled steel tubular columns.

[0008] Furthermore, the steel plate is provided with a cylindrical hole passing through the cuboid column and matching with the concrete-filled steel tubular column; circular positioning holes are arranged at the four corners of the side of the steel plate, and elliptical fixing holes are symmetrically arranged on the four sides of the side of the steel plate.

[0009] Furthermore, the cuboid column is provided with two pairs of connection holes with clearance fit, and the axes of each pair of connection holes are perpendicular to each other; the support plate includes a support rod connecting adjacent cuboid columns, and support connecting plates connected with the cuboid column are symmetrically arranged at both ends of the support rod.

[0010] Furthermore, there are two reserved holes on the concrete-filled steel tube column, the center lines of which are perpendicular to each other and are matched with the connection holes. The reserved holes are matched with the connection bolts respectively arranged in a pair of connection holes.

[0011] Furthermore, the axes of the reserved holes are respectively arranged at one-third and two-thirds of the longitudinal direction of the concrete-filled steel tube column.

[0012] Furthermore, the diameter of the concrete-filled steel tube column is smaller than the diameter of the cylindrical hole.

[0013] Furthermore, triangular support plates matched with the rectangular column are arranged at the four corners on the side of the steel plate close to the rectangular column, and one side of the triangular support plate is connected to the edge of the rectangular column.

[0014] Furthermore, the number of the rectangular columns is four.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The present utility model connects the concrete-filled steel tube column and the assembled sleeve component by an assembly method, which can significantly improve the disassembly, assembly and construction efficiency of the concrete-filled steel tube column and the assembled sleeve component, and can shorten the construction period; the assembled sleeve component connects the steel plates through four rectangular columns to form a stable vertical support structure, thereby significantly improving the vertical bearing capacity of the assembled concrete-filled steel tube lattice column structure; the assembled sleeve component of the present utility model is assembled by prefabricated plates, which is convenient for quickly connecting and assembling according to needs, and is convenient for quickly disassembling after use.
