Description

Technical Field

[0001] This utility model belongs to the field of box column installation technology, specifically relating to a box column elevation adjustment device. Background Technology

[0002] Box columns are widely used in the construction of steel structure buildings, large stadiums, industrial plants, and bridges due to their excellent compressive, bending, and torsional resistance. A box column is typically a hollow rectangular section steel column welded from four steel plates, with a reasonable distribution of cross-sectional material and high structural stability. In actual installation, box columns are often installed section by section using a method of segmented hoisting and on-site docking.

[0003] The existing technology involves hoisting the upper box column and initially placing it on the already installed and fixed lower box column, and then connecting the upper and lower box columns by welding.

[0004] However, a common technical problem exists in this process: due to manufacturing errors and foundation settlement, after the upper box column is initially positioned, its elevation cannot accurately reach the design elevation required by the design. How to adjust the elevation of the upper box column is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a box-type column elevation adjustment device that can accurately adjust the elevation of the first box-type column. At the same time, after the precise adjustment is in place, the cylinder itself can serve as a rigid support point to keep the column body stable, providing a flat and stable interface condition for subsequent high-quality butt welding, effectively ensuring the final welding quality and the installation accuracy of the overall structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A box-shaped column elevation adjustment device includes a first box-shaped column and a second box-shaped column distributed vertically. Its key feature is that it further includes a cylinder; the second box-shaped column has a fixed base welded to it, and the cylinder is fixed to the fixed base; the first box-shaped column has a support base welded to it, and the cylinder supports the support base. By lifting the support base with the cylinder, the first box-shaped column can be moved vertically to a set height.

[0008] Furthermore, it also includes a clamping structure and an adjusting structure. The clamping structure is fixed on the second box-shaped column, and the adjusting structure is fixed on the first box-shaped column. The adjusting structure can make adjustments in the X-axis and Y-axis directions on the plane at the clamping structure and perform limiting to align the first box-shaped column and the second box-shaped column. The adjusting structure adjusts the height for vertical movement of the first box-shaped column.

[0009] Furthermore, the clamping structure includes angle steel one and angle steel two, which are fixed together and clamp the second box-shaped column. Angle steel one is provided with a slot. The adjusting structure includes a connector, a fixing plate, and a clamping plate. The connector is fixed to the first box-shaped column, and the fixing plate is installed on the connector and vertically adjusted on the connector. The bottom of the fixing plate is provided with a threaded post that passes through the slot and through the through hole one of the clamping plate. The bottom of the clamping plate and the fixing plate clamp angle steel one. The threaded post is threadedly connected to a nut one, which is locked onto the clamping plate.

[0010] Furthermore, the connector is made of angle steel three, which has a through hole two. The support seat also has a through hole three. A threaded rod passes through the through hole three and through the through hole two. The angle steel three is tightly attached to the surface of the first box column. The threaded rod is threadedly connected to a nut two, which is locked onto the angle steel three.

[0011] Furthermore, a vertical plate is fixed to the bottom of the connector. The vertical plate has mounting holes. A fixing bolt is installed through the four through holes of the fixing plate. The fixing bolt passes through the mounting holes and moves vertically in the mounting holes. The fixing bolt is threaded with a nut.

[0012] Furthermore, the fixing plate has an opening, which is located on one side of the connection between the first box column and the second box column.

[0013] Furthermore, a reinforcing plate is welded to the fixing plate, and the reinforcing plate has a second opening, the inner wall of which is aligned with the inner wall of the first opening.

[0014] Furthermore, angle steel 2 is welded with a connecting block, the connecting block is welded with a connecting column, angle steel 1 is provided with a through hole 5, the connecting column passes through the through hole 5, the connecting column is threaded with a nut 4, and the nut 4 is locked onto angle steel 1.

[0015] Furthermore, a top plate is fixed to the top of the cylinder, and a bottom plate is fixed to the bottom of the cylinder. The bottom plate is detachably connected to the fixed seat, and the support seat is supported on the top plate.

[0016] Furthermore, mounting bolts are installed on the base plate and the fixed seat, and the mounting bolts are threaded with nuts.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] This utility model has a fixed seat welded to the outside of the second box-shaped column and a support seat welded to the outside of the first box-shaped column, so that the cylinder has sufficient installation space, forming a stable transmission system and improving the safety of the lifting process.

[0019] By extending and retracting the piston rod of the cylinder, the lifting height of the first box-shaped column can be precisely controlled, allowing for accurate adjustment of its elevation.

Detailed Implementation

[0032] like Figures 1 to 10 As shown, this utility model's box-shaped column elevation adjustment device uses a cylinder to adjust the elevation of the upper box-shaped column.

[0033] Example 1,

[0034] This utility model includes a first box-shaped column 12 and a second box-shaped column 4. The second box-shaped column 4 is located below and has been installed and fixed. The first box-shaped column 12 is located above the second box-shaped column 4 and is placed on the second box-shaped column 4 by hoisting. The first box-shaped column 12 and the second box-shaped column 4 have the same structure.

[0035] A fixed seat 5 is welded to the outside of the second box-shaped column 4. A top plate 3 is fixed to the top of the piston rod of cylinder 1, and a bottom plate 2 is fixed to the bottom of the cylinder 1 housing. Mounting bolts 29 pass through the bottom plate 2 and the fixed seat 5, and nuts 30 are threaded onto the mounting bolts 29, so that cylinder 1 is fixed on the fixed seat 5, and cylinder 1 has sufficient installation space. A support seat 13 is welded to the outside of the first box-shaped column 12. When the first box-shaped column 12 is hoisted and initially placed on the second box-shaped column 4, the top plate 3 of cylinder 1 supports the support seat 13, forming a stable transmission system and improving the safety of the lifting process. By extending and retracting the piston rod of cylinder 1, the lifting height of the first box-shaped column 12 can be precisely controlled, and the elevation of the first box-shaped column 12 can be precisely adjusted. Moreover, after the first box-shaped column 12 is precisely adjusted into place, cylinder 1 itself can act as a rigid support point to keep the column body stable, providing a flat and stable interface condition for subsequent high-quality butt welding, effectively ensuring the final welding quality and the installation accuracy of the overall structure.

[0036] Example 2,

[0037] When the first box-shaped column 12 is placed on the second box-shaped column 4, there is a misalignment between the column opening of the second box-shaped column 4 and the column opening of the first box-shaped column 12. Furthermore, the first box-shaped column 12 is supported by its own weight on the cylinder 1. During subsequent welding, or due to external disturbances (such as wind load or collision), the first box-shaped column 12 may experience horizontal displacement or swaying. To address this technical problem, this utility model, based on the structure of Embodiment 1, adds a clamping structure and an adjustment structure.

[0038] The clamping structure includes angle steel 6 and angle steel 8. Angle steel 8 is welded with a connecting block 11, and the connecting block 11 is welded with a connecting column 9. Angle steel 6 has a through hole 5, through which the connecting column 9 passes. The connecting column 9 is threadedly connected to a nut 10, which locks onto angle steel 6, thus fixing angle steel 6 and angle steel 8. Angle steel 6 and angle steel 28 clamp the second box-type column 4. The fixing method of angle steel 6 and angle steel 28 causes less damage to the second box-type column 4, facilitates later disassembly, and allows adjustment of the height of the clamping structure on the second box-type column 4. When the first box-type column 12 is not hoisted, the clamping structure is fixed at the set height of the second box-type column 4.

[0039] The adjustment structure includes a connector, a fixing plate 21, and a clamping plate 32. The connector is made of angle steel 15, which has a through hole 16. The support base 13 has a through hole 14, through which a threaded rod 19 passes. The threaded rod 19 passes through the through hole 16. The angle steel 15 is tightly attached to the surface of the first box-shaped column 12. The threaded rod 19 is threadedly connected to a nut 20, which locks onto the angle steel 15, thus fixing the angle steel 15 in place. Figure 6 As shown. A vertical plate 17 is fixed to the bottom of the connector, and the vertical plate 17 has mounting holes 18. A fixing bolt 23 passes through the through hole 28 of the fixing plate 21. The fixing bolt 23 passes through the mounting hole 18 and moves vertically in the mounting hole 18. The fixing bolt 23 is threadedly connected to a nut 24. When the first box column 12 is not lifted, the nut 24 is in a loose state, such as... Figure 7 As shown. Before hoisting the first box column 12, the connector is fixed to the first box column 12.

[0040] The bottom of the fixed plate 21 is provided with a threaded post 22, and the angle steel 6 is provided with a slot 7. The threaded post 22 passes through the slot 7. The slot 7 provides space for the threaded post 22 to move, but also limits the range of movement of the threaded post 22 to prevent over-adjustment. When the first box-shaped post 12 is hoisted and placed on the second box-shaped post 4, the operator can visually observe the misalignment of the upper and lower post openings. Then, by gently tapping the angle steel 3 15, the operator can make slight horizontal adjustments to the first box-shaped post 12 in the X-axis and Y-axis directions, thereby correcting the positional deviation of the first box-shaped post 12 and ensuring that the post opening of the second box-shaped post 4 is aligned with the post opening of the first box-shaped post 12, thus improving the subsequent welding quality. Figure 9As shown.

[0041] After the horizontal position of the first box-shaped column 12 is adjusted, a clamping plate 32 is installed on the fixing plate 21. The threaded column 22 passes through the through hole of the clamping plate 32, and a nut 31 is threaded onto the threaded column 22. The nut 31 is then locked onto the clamping plate 32, so that the clamping plate 32 and the bottom of the fixing plate 21 firmly clamp the angle steel 6. This "clamping and locking" mechanism forms a stable temporary connection, which can effectively prevent the first box-shaped column 12 from shifting or swaying horizontally during subsequent welding or due to external disturbances (such as wind load or collision), providing safety and stability for high-altitude welding operations.

[0042] When cylinder 1 lifts the support seat 13, the vertical plate 17 moves vertically between the fixed plates 21, precisely adjusting the elevation of the first box-shaped column 12. The first box-shaped column 12 is then moved vertically to the designed height. Finally, nut 24 is tightened, forming interface a between the first box-shaped column 12 and the second box-shaped column 4. Figure 10 As shown. A connecting plate can be welded at interface a, so that the first box column 12 is fixed to the second box column 4 through the connecting plate.

[0043] The fixing plate 21 has an opening 26, which is located on one side of the connection between the first box column 12 and the second box column 4, increasing the welding operation space. The fixing plate 21 is welded with a reinforcing plate 25, which has an opening 27. The inner wall of the opening 27 is aligned with the inner wall of the opening 26. The opening weakens the local rigidity of the fixing plate 21, but the welding of the reinforcing plate 25 can compensate for the rigidity loss.

[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
