Embodiment 1

[0040] Such as figure 1 and figure 2 As shown, the circular hollow interlayer splicing column according to the present invention includes an outer cylindrical column 1 formed by vertical insertion and fixing of at least two skeleton units, and an inner cylindrical column member fixed in the outer cylindrical column 1, The inner wall of the outer cylindrical pipe 1 is welded with at least one anti-slip groove 5; the inner cylindrical pipe member includes an inner cylindrical pipe 2 arranged concentrically with the outer cylindrical pipe 1, and several vertically welded outer walls of the inner cylindrical pipe 2. Steel partitions 3 of equal length, the steel partitions 3 are spaced from each other and the ends are provided with anti-off heads 8 matching with anti-off grooves 5; the inner cylindrical column 2 is inserted through the anti-off heads 8 of the steel partitions The anti-detachment groove 5 connected to the outer cylindrical column 1 is fixed; the vertical heights o...

Embodiment 2

[0046] The cross-sections of the skeleton units in the present invention can be varied, and the outer cylindrical pipe string 1 can also be spliced ​​by various skeleton units.

[0047] For example, as shown in Fig. 3(a), the cross-section of the skeleton unit is 90° fan-shaped. Such as figure 1 and figure 2 As shown, the outer cylindrical pipe string 1 is spliced ​​by four skeleton units whose sections are 90° fan-shaped.

[0048] As shown in Fig. 3(b), the cross-section of the skeleton unit is 180° fan-shaped. Such as Figure 6 and Figure 7 As shown, the outer cylindrical pipe string 1 is spliced ​​by two skeleton units whose sections are 180° fan-shaped.

[0049] As shown in Fig. 3(c), the cross-section of the skeleton unit is 270° fan-shaped. Such as Figure 8 and Figure 9 As shown, the outer cylindrical pipe string 1 is spliced ​​by a skeleton unit with a sector-shaped cross section of 90° and a skeleton unit with a sector-shaped cross-section of 270°.

Embodiment 3

[0051] In the frame unit of the present invention, the vertical height dimensions of the left and right sides are inconsistent.

[0052] For example, if figure 1 There are multiple skeleton units in the perspective view shown, among which, among the skeleton units in the lower layer, the vertical height dimensions of the leftmost and rightmost skeleton units are smaller than the vertical height dimensions of the middle skeleton units; similarly, the upper layer Among the skeletal units of , the vertical height dimensions of the leftmost and rightmost skeletal units are larger than the vertical height dimensions of the middle side skeletal units. In this way, the skeleton units of the lower layer and the upper layer cooperate to form a complete outer cylindrical pipe string 1 .

[0053] Such as Figure 6 There are multiple skeleton units in the perspective view shown, among them, in the skeleton unit of the lower layer, the vertical height dimension of the left side is larger...

Abstract

The invention relates to a circular hollow interlayer splicing column and a construction method thereof, and belongs to the technical field of building steel structure construction. The circular hollow interlayer splicing column comprises an outer circular pipe column formed by vertically inserting and fixing at least two skeleton units, and an inner circular pipe column member fixed in the outercircular pipe column; the inner wall of the outer circular pipe column is welded with at least one anti-drop groove; the inner tubular column member comprises an inner circular pipe column concentrically arranged with the outer circular pipe column, and a plurality of equal length steel partition plates welded perpendicularly along the outer wall of the inner circular pipe column; the steel partition plates are spaced apart from each other and anti-drop heads matched with the anti-drop grooves are arranged at ends of steel partition plates; the inner circular pipe column is fixed by insertingthe anti-drop heads of the steel partition plates into the anti-drop grooves of the outer circular pipe column; and the heights of the skeleton units at the left side and the right side of the bottomlayer is inconsistent in the vertical direction and the two skeleton units are staggered up and down. By adopting the circular hollow interlayer splicing column, the problems that the connection modeof the existing circular hollow interlayer splicing column is inconvenient in on-site construction operation, the connecting member is complicated in design and construction, and pitch points are insufficient in stiffness, and difficult in welding at present are solved.

Description

technical field [0001] The invention relates to a circular hollow interlayer splicing column and a construction method thereof, belonging to the technical field of building steel structure construction. Background technique [0002] In recent years, concrete-filled steel pipe columns have been widely used in practical projects. Compared with pure steel reinforced concrete members, they can significantly reduce the amount of steel used, reduce the cost of structures, and improve the fire resistance of steel members; steel pipes can be used as templates for pouring concrete , eliminating the need for reinforced concrete components formwork and demolition process, significantly improving the construction speed of the structure. [0003] The prefabricated steel structure is in a period of vigorous development, and it is an important way for the development of building industrialization, and the connection between columns occupies a very important position in the prefabricated st...
