Technical Field
[0001] This utility model relates to the technical field of heavy steel structure box columns, specifically a deformation-resistant heavy steel structure box column. Background Technology
[0002] As the core load-bearing component of modern high-rise buildings, bridges, and large-span spatial structures, heavy steel box columns require a systematic solution to three core issues in their design, manufacturing, and installation: strength, stability, and deformation control. Existing box columns typically require stiffening diaphragms to increase local strength and reduce welding deformation. These stiffening diaphragms are usually made of steel plates, which can easily increase the weight of the box column. Furthermore, the stiffening diaphragms are usually welded to the box column, which can easily increase thermal deformation and thus affect the processing of the box column. Utility Model Content
[0003] To address the above problems, the purpose of this utility model is to provide a deformation-resistant heavy-duty steel box column. This solves the problem that existing box columns usually require stiffening diaphragms to increase local strength and reduce welding deformation. Existing stiffening diaphragms are usually made of steel plates, which can easily increase the weight of the box column. Furthermore, the stiffening diaphragms are usually welded to the box column, which can easily increase thermal deformation and thus affect the processing of the box column.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a deformation-resistant heavy-duty steel structure box column, comprising a box column body, a stiffening partition plate is provided inside the box column body, and a grid rib plate is integrally formed on the outer side of the stiffening partition plate. A wear-resistant cover is welded to the outer side of the stiffening partition plate. Bolts are installed through the box column body, and anti-slip pads are sleeved at the connection between the bolts and the box column body. A cable conduit is welded through the middle part of the stiffening partition plate.
[0005] The beneficial effects of this utility model are as follows: by using bolts in conjunction with anti-slip pads to fix the stiffening partition plate inside the box-shaped column body, the deformation of the box-shaped column body can be effectively reduced. Fixing the stiffening partition plate with bolts can effectively reduce welding, thereby reducing the thermal deformation caused by welding.
[0006] The weight of the box column can be effectively reduced by using the gradually thinning stiffening baffles and hexagonal through holes.
[0007] To increase the structural strength of the stiffening diaphragm:
[0008] As a further improvement to the above technical solution: the stiffening partition plate has a protrusion integrally formed on the side away from the grid rib plate.
[0009] The beneficial effect of this improvement is that the stiffening partition can be easily installed inside the box column body by bolts through the protrusion.
[0010] To facilitate the connection between the bolts and the stiffening plate:
[0011] As a further improvement to the above technical solution: the bolt and the stiffening partition are connected by threads.
[0012] The beneficial effect of this improvement is that the threaded connection makes it easy to fix the stiffening diaphragm inside the box column body with bolts.
[0013] To reduce the weight of the stiffening partition:
[0014] As a further improvement to the above technical solution: hexagonal through holes are equally spaced on the stiffening partition.
[0015] The beneficial effect of this improvement is that the weight of the stiffening partition can be effectively reduced through the through holes.
[0016] As a further improvement to the above technical solution: the thickness of the stiffening baffle is gradually reduced from the end of the box-shaped column body to the middle position of the box-shaped column body.
[0017] The beneficial effect of this improvement is that the weight of the stiffening partition can be effectively reduced while ensuring strength by using a gradually thinning stiffening partition.
[0018] To ensure structural strength:
[0019] As a further improvement to the above technical solution: the stiffening baffle and the end face of the box-shaped column body are arranged parallel to each other.
[0020] The beneficial effect of this improvement is that the parallel arrangement of the stiffening diaphragms makes the reinforcement of the box column body more reliable and accurate.
[0021] To facilitate the fixing of the stiffening partition:
[0022] As a further improvement to the above technical solution: the bolts are symmetrically distributed on the outside of the box-shaped column body.
[0023] The beneficial effect of this improvement is that the symmetrically distributed bolts can reliably and securely install the stiffening diaphragm inside the box column body.
[0024] To ensure the location of the cable conduit:
[0025] As a further improvement to the above technical solution: the wiring conduit and the box-shaped column body are arranged with their centerlines overlapping.
[0026] The beneficial effect of this improvement is that the symmetrically arranged cable trays along the centerline facilitate the passage of the cable harness. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0034] like Figure 1-5As shown, a deformation-resistant heavy-duty steel box-type column includes a box-type column body 1. A stiffening partition 2 is provided inside the box-type column body 1, and a mesh rib 21 is integrally formed on the outer side of the stiffening partition 2. A wear-resistant cover 22 is welded to the outer side of the stiffening partition 2. Bolts 3 are installed through the box-type column body 1, and anti-slip pads 31 are fitted at the connection points between the bolts 3 and the box-type column body 1. A cable conduit 4 is welded through the middle portion of the stiffening partition 2. The bolts 3 and the anti-slip pads are used in conjunction with this design. 31. The stiffening partition 2 is fixed inside the box-shaped column body 1. This method can effectively reduce the deformation of the box-shaped column body 1. Fixing the stiffening partition 2 with bolts 3 can effectively reduce welding, thereby reducing the thermal deformation caused by welding. When using this box-shaped column, the gradually thinning stiffening partition 2 and the hexagonal through holes can effectively reduce the weight of the box-shaped column. The side of the stiffening partition 2 away from the grid rib 21 is integrally formed with a protrusion, which facilitates the installation of the stiffening partition 2 with bolts 3. Inside the box-type column body 1, the bolts 3 and the stiffening baffle 2 are connected by threads. The threaded connection allows the bolts 3 to easily fix the stiffening baffle 2 inside the box-type column body 1. The stiffening baffle 2 has hexagonal through holes at equal intervals, which can effectively reduce the weight of the stiffening baffle 2. The thickness of the stiffening baffle 2 gradually decreases from the end of the box-type column body 1 to the middle position. The gradually thinning stiffening baffle 2 can effectively reduce the weight of the stiffening baffle 2 while ensuring strength. The end faces of the stiffening baffle 2 and the box-type column body 1 are arranged parallel to each other. The parallel arrangement makes the reinforcement of the box-type column body 1 by the stiffening baffle 2 more reliable and accurate. The bolts 3 are symmetrically distributed on the outside of the box-type column body 1. The symmetrically distributed bolts 3 can reliably and firmly install the stiffening baffle 2 inside the box-type column body 1. The cable tray 4 is arranged with its centerline coincident with the box-type column body 1. The symmetrically arranged cable tray 4 with its centerline coincident can facilitate the passage of the cable harness.
[0035] The working principle of this utility model is as follows: When using this device, the stiffening partition 2 is inserted into the interior of the box-shaped column body 1, and then the stiffening partition 2 is fixed inside the box-shaped column body 1 using bolts 3 and anti-slip pads 31. This method can effectively reduce the deformation of the box-shaped column body 1. When using the box-shaped column, the weight of the box-shaped column can be effectively reduced by the gradually thinning stiffening partition 2 and the hexagonal through hole. The wiring conduit 4 can facilitate the passage of wire harnesses inside the box-shaped column. Fixing the stiffening partition 2 with bolts 3 can effectively reduce welding, thereby reducing the thermal deformation caused by welding.
