Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a box-type structure with built-in well-shaped nodes. Background Technology

[0002] Traditional box-type components only have transverse diaphragms in the node area, and the diaphragms are aligned with the flanges of the cantilever beam. This structure is prone to stress concentration in the node area, especially under high loads or dynamic loads (such as earthquakes and wind loads), which may lead to local buckling or fatigue failure.

[0003] Traditional column-beam connections mainly rely on welding or bolting. The flanges of the cantilever beam are aligned with the transverse diaphragms inside the box column, but the web of the cantilever beam often lacks sufficient support at the connection with the box, resulting in insufficient node stiffness and affecting the stability and load-bearing capacity of the overall structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a box-type structure with built-in grid-shaped nodes. The structural strength of the box-type main body can be enhanced by welding and fixing the grid-shaped partitions with the horizontal partitions. The alignment between the box-type brackets and the grid-shaped partitions can achieve torque transmission, further enhancing the shear and bending resistance of the nodes.

[0005] This utility model is achieved through the following technical solution:

[0006] A box-shaped structure with built-in grid-like partitions is provided, including a box-shaped main body and box-shaped brackets connected to the outer side of the box-shaped main body. Horizontal partitions are arranged vertically within the inner cavity of the box-shaped main body, and a vertical partition is connected between the two horizontal partitions. The two horizontal partitions are aligned with the upper and lower flanges of the box-shaped brackets and welded to the inner wall of the inner cavity of the box-shaped main body. The vertical partition includes two vertically parallel and spaced-apart through partitions. Two parallel and spaced-apart inner partitions are vertically welded between the two through partitions opposite each other. External partitions located on the same plane as the inner partitions are welded to the back-to-back sides of the two through partitions. The external partitions, inner partitions, and through partitions are spliced ​​together to form a grid-like partition. The two external partitions or two through partitions at each end of the grid-like partition are aligned with the two side webs of the box-shaped brackets and welded to the inner wall of the inner cavity of the box-shaped main body.

[0007] Furthermore, the heights of the outer partition, inner partition, and through partition are all kept consistent.

[0008] The outer partition, inner partition, and through partition are all at the same height, which allows them to be connected and fixed to the transverse partition, ensuring connection strength and stability.

[0009] Furthermore, both the outer and inner partitions have 45° chamfers at their four corners.

[0010] Furthermore, the four corners of the through partition are each chamfered at 45°.

[0011] Preferably, the box-shaped body is formed by welding four steel plates sequentially along its length, with steel gaskets provided at the weld seams of adjacent steel plates.

[0012] Furthermore, a column top plate is welded to the open end of the box-shaped main body, and lifting lugs are provided on the column top plate.

[0013] The top open end of the box-shaped main body is fixed by welding the column top plate. The lifting lugs on the column top plate can be used for on-site hoisting to straighten and fix the box-shaped main body, which facilitates the connection and installation of the cross beams and longitudinal beams.

[0014] The beneficial effects of this utility model are:

[0015] This invention welds and fixes a grid-like partition, composed of through partitions, outer partitions, and inner partitions, into the inner cavity of the box-type main body. By controlling the alignment and welding of the two outer partitions or two through partitions at the ends of the grid-like partitions with the two side webs of the box-type bracket, the force of the box-type bracket can be transferred to the grid-like partitions in the inner cavity of the box-type main body. The grid-like partitions can distribute the load more evenly, avoid excessive local stress, thereby improving the fatigue life and seismic performance of the structure. It not only enhances the connection strength of the box-type main body but also improves the stability of the nodes, enhances the overall structural strength, ensures the horizontal force transmission of the box-type steel beam, and makes the overall structure more stable and safer.

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] Example 1:

[0025] like Figures 1-3 As shown, a box-shaped structure with built-in well-shaped nodes is installed at the top of a column, including a box-shaped main body 1 and a box-shaped bracket 2 connected to the outer side of the top of the column of the box-shaped main body 1, as shown. Figure 1 As shown, box-shaped brackets 2 are provided on all four sides of the box-shaped main body 1. The box-shaped main body 1 is formed by welding four steel plates sequentially along its length, and steel gaskets 7 are provided at the weld seams of adjacent steel plates. A column top plate 5 is welded to the open end of the top of the box-shaped main body 1, and lifting lugs 6 are provided on the column top plate 5.

[0026] A horizontal partition 11, parallel to and below the column top plate 5, is installed in the inner cavity of the column top of the box-shaped main body 1. A vertical partition connects the column top plate 5 and the horizontal partition 11. The column top plate 5 and the horizontal partition 11 are aligned with and welded to the upper and lower flange plates 4 of the box-shaped bracket 2, respectively, and fixed to the inner wall of the inner cavity of the box-shaped main body 1. The vertical partition includes two vertically parallel and spaced through partitions 8. Two parallel and spaced inner partitions 10 are vertically welded between the two through partitions 8. External partitions 9, located on the same plane as the inner partitions 10, are welded to the back-to-back sides of the two through partitions 8. The external partitions 9, inner partitions 10, and through partitions 8 are spliced ​​together to form a grid-like partition. The heights of the external partitions 9, inner partitions 10, and through partitions 8 are all consistent. The four corners of the external partitions 9 and inner partitions 10 are all chamfered at 45°. The four corners of the through partitions 8 are also chamfered at 45°.

[0027] The two outer partitions 9 or two through partitions 8 at each end of the grid partition are aligned with the two side webs 3 of the box-shaped bracket 2 and welded to the inner wall of the box-shaped body 1.

[0028] During installation, the upper and lower flanges 4 of the box-shaped brackets 2 on the outer side wall of the box-shaped main body 1 are aligned with the column top plate 5 of the box-shaped main body 1 and the transverse partition 11 in the inner cavity. The two side webs 3 of the box-shaped brackets 2 are aligned with the vertical partitions in the inner cavity of the box-shaped main body 1. The vertical partitions are set as grid partitions, and their four ends are respectively aligned with and welded to the box-shaped brackets 2 on the four sides of the box-shaped main body 1.

[0029] The vertical diaphragms and the wall panels of the box-type main body 1 must form an integral structure to ensure the horizontal force transmission of the box-type steel beams. Before assembling the column top plate 5, the horizontal diaphragms 11 and the grid diaphragms are first welded and fixed to the inner wall of the box-type main body 1. Then, the column top plate 5 is welded to the top of the box-type main body 1. The area of ​​the column top plate 5 is slightly larger than the cross-section of the box-type main body 1. When welding the column top plate 5, the middle of the bottom surface of the column top plate 5 is welded to the end face of the box-type main body 1. The bottom surfaces of the four sides of the column top plate 5 are welded and fixed to the upper flange plates 4 of the corresponding box-type brackets 2. Finally, the external box-type brackets 2 are assembled, completing the welding of the box-type brackets 2 to the box-type main body 1 and the box-type brackets 2 to the column top plate 5. The lifting lugs 6 on the column top plate 5 facilitate on-site hoisting, allowing the welded box-type structure to be erected and upright as a whole, so that the box-type crossbeams can be welded and fixed on the box-type brackets 2.

[0030] Example 2:

[0031] A box-type structure with built-in well-shaped nodes, its installation position is below the top of the box-type main body 1, such as... Figures 4-5 As shown, it includes a box-shaped main body 1 and a box-shaped bracket 2 connected to the outer side of the column top of the box-shaped main body 1, as follows. Figure 4 As shown, box-shaped brackets 2 are provided on all four sides of the box-shaped body 1. The box-shaped body 1 is formed by welding four steel plates in sequence along the length direction, and steel gaskets 7 are provided at the weld seams of two adjacent steel plates.

[0032] Two horizontal partitions 11 are arranged vertically within the inner cavity of the box-shaped main body 1, and a vertical partition is connected between the two horizontal partitions 11. The two horizontal partitions 11 are aligned with the upper and lower flanges 4 of the box-shaped bracket 2 and welded to the inner wall of the inner cavity of the box-shaped main body 1. The vertical partition includes two vertically parallel and spaced through partitions 8. Two parallel and spaced inner partitions 10 are vertically welded between the two through partitions 8. Outer partitions 9, located on the same plane as the inner partitions 10, are welded to the back-to-back sides of the two through partitions 8. The outer partitions 9, inner partitions 10, and through partitions 8 are spliced ​​together to form a grid-like partition. The heights of the outer partitions 9, inner partitions 10, and through partitions 8 are all consistent. The four corners of the outer partitions 9 and inner partitions 10 are all chamfered at 45°. The four corners of the through partitions 8 are also chamfered at 45°.

[0033] The two outer partitions 9 or two through partitions 8 at each end of the grid partition are aligned with the two side webs 3 of the box-shaped bracket 2 and welded to the inner wall of the box-shaped body 1.

[0034] By welding and fixing a grid-like partition formed by splicing through partitions 8, outer partitions 9, and inner partitions 10 into the inner cavity of the box-type main body 1, and by controlling the two outer partitions 9 or the two through partitions 8 at the ends of the grid-like partitions to be aligned with and welded to the two side webs of the box-type corbel 2, the force of the box-type corbel 2 can be transferred to the grid-like partition in the inner cavity of the box-type main body 1. The grid-like partition can distribute the load more evenly, avoid excessive local stress, thereby improving the fatigue life and seismic performance of the structure. It not only enhances the connection strength of the box-type main body 1, but also improves the node stability, enhances the overall structural strength, ensures the horizontal force transmission of the box-type steel beam, and makes the overall structure more stable and safe.
