Method used

In the present invention, components such as circular hollow interlayer splicing column splicing parts are standardized in factories, and the quality is more guaranteed than on-site production. When transported to the scene, they can be directly installed, and the construction process does not need to wait, which saves time and cost; The circular hollow interlayer splicing column in the present invention has a built-in circular hollow interlayer which can not only increase the rigidity of the column wall in the joint area, facilitate the transmission of force in the joint area, enhance the bearing capacity and anti-seismic performance...

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.

Example Embodiment

[0039] Example 1:

[0040] Such as figure 1 with figure 2 As shown, the circular hollow sandwich splicing column of the present invention includes an outer tubular column 1 formed by vertical insertion and fixing of at least two skeleton units, and an inner tubular column member fixed in the outer tubular column 1, and The inner wall of the outer tube string 1 is welded with at least one anti-drop groove 5; the inner tube string component includes an inner tube string 2 arranged concentrically with the outer tube string 1, and a number of vertically welded along the outer wall of the inner tube string 2. Blocks of equal-length steel partitions 3, the steel partitions 3 are spaced apart from each other, and the ends are provided with anti-dropping heads 8 matching with the anti-dropping grooves 5; the inner circular pipe string 2 is inserted through the anti-dropping heads 8 of the steel partition 3 The anti-drop groove 5 connected to the outer cylindrical column 1 is fixed; the frame units on the left and right sides of the bottom layer are not uniform in vertical height and are arranged staggered up and down.

[0041] A rubber ring 6 is installed between the upper and lower frame units.

[0042] The cross section of the inner circular pipe column member is ¤-shaped, and the steel partitions 3 are arranged at 90° intervals.

[0043] Concrete 4 is filled between the outer tubular column 1 and the inner tubular column member.

[0044] Four anti-drop grooves 5 are provided on the inner wall of the outer tube string 1, and the anti-drop grooves 5 are arranged at 90° intervals along the inner wall.

Example Embodiment

[0045] Example 2:

[0046] The cross section of the skeleton unit of the present invention can be varied, and the outer cylindrical pipe string 1 can also be formed by splicing multiple skeleton units.

[0047] For example, as shown in Fig. 3(a), the cross section of the skeleton unit is a 90° sector. Such as figure 1 with figure 2 As shown, the outer tubular column 1 is formed by splicing four frame units with a cross section of a 90° sector.

[0048] As shown in Figure 3(b), the cross-section of the skeleton unit is a 180° sector. Such as Image 6 with Figure 7 As shown, the outer tube string 1 is formed by splicing two frame units with a 180° sector shape in cross section.

[0049] As shown in Figure 3(c), the cross-section of the skeleton unit is 270° sector-shaped. Such as Figure 8 with Picture 9 As shown, the outer cylindrical column 1 is formed by splicing a frame unit with a 90° sector shape in cross section and a frame unit with a 270° sector shape in cross section.

Example Embodiment

[0050] Example 3:

[0051] In the framework unit of the present invention, the vertical height dimensions on the left and right sides are not consistent.

[0052] For example, such as figure 1 There are multiple skeleton units in the three-dimensional view shown. Among the skeleton units in the lower layer, the vertical height dimensions of the leftmost and rightmost skeleton units are both smaller than the vertical height dimensions of the middle side skeleton unit; similarly, the upper layer Among the skeleton units, the vertical height dimensions of the leftmost and rightmost skeleton units are larger than the vertical height of the middle skeleton unit. As a result, the lower layer and the upper layer skeleton units cooperate to form a complete outer cylindrical column 1.

[0053] Such as Image 6 There are multiple skeleton units in the three-dimensional view shown. Among the skeleton units of the lower layer, the vertical height of the left side is greater than the vertical height of the right side of the skeleton unit; in the same way, in the upper layer of the skeleton unit, the left vertical The height dimension is smaller than the vertical height dimension of the skeleton unit on the right. As a result, the lower layer and the upper layer skeleton units cooperate to form a complete outer cylindrical column 1.

[0054] Such as Figure 8 There are multiple skeleton units in the three-dimensional view shown. Among the skeleton units in the lower layer, the vertical height of the left side is smaller than that of the right skeleton unit; in the same way, in the upper skeleton unit, the left vertical The height dimension is greater than the vertical height dimension of the skeleton unit on the right. As a result, the lower layer and the upper layer skeleton units cooperate to form a complete outer cylindrical column 1.
