It addresses the problem of internal stress causing deformation in box-type steel structure columns when subjected to external loads, temperature changes, welding, and other factors. The invention includes a mounting plate with four circumferentially distributed main steel plates welded to its top surface. Corner steel plates are welded to the corners where the four main steel plates meet. Multiple sets of uniformly distributed stress relief units are provided on the inner walls of the four main steel plates.

Description

Technical Field

[0001] This utility model relates to the field of box column technology, specifically a box-type steel structure support column with an internal stress relief structure. Background Technology

[0002] Box-type steel structure columns, also known as box columns, are a type of steel structure component widely used in building construction. They have a closed rectangular or square cross-section and high load-bearing capacity.

[0003] In existing technologies, when a support column is subjected to external loads, temperature changes, welding and other factors, stress concentration will occur inside the support column. If it is under stress concentration for a long time, the support column is prone to deformation, cracking and other problems, which seriously affect its service life and safety.

[0004] Therefore, a box-type steel structure column with an internal stress relief structure is needed to solve the problem that existing box-type steel structure columns will deform due to internal stress caused by external loads, temperature changes, welding and other factors. Utility Model Content

[0005] The purpose of this utility model is to provide a box-type steel structure support column with an internal stress relief structure, so as to solve the problem that the box-type steel structure support column in the prior art will generate internal stress and cause the support column to deform when it is affected by external loads, temperature changes, welding and other factors.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a box-type steel structure support column with an internal stress relief structure, comprising an mounting plate and four main steel plates welded to the top surface of the mounting plate in a circular arrangement, wherein corner steel plates are welded to the corners where the four main steel plates meet, and multiple sets of stress relief units are provided on the inner walls of the four main steel plates in a uniform arrangement.

[0007] Each stress relief unit includes two symmetrically distributed connecting plates mounted on the main steel plate and an arc-shaped elastic plate mounted between the two connecting plates, wherein the inner concave surface of the arc-shaped elastic plate is away from the corresponding main steel plate.

[0008] It should be noted in the plan that three evenly distributed reinforcing steel plates are welded between each two adjacent end angle steel plates, and X-shaped reinforcing ribs are welded between each two adjacent reinforcing steel plates.

[0009] It is worth noting that a reinforcing plate is welded between the top surface of the mounting plate and the outer surface of each end angle steel plate.

[0010] It should be further noted that each of the aforementioned arc-shaped elastic plates is spaced apart from the corresponding main steel plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The curved elastic plate absorbs the stress generated by the box-type steel structure column, and the connecting plate transfers the stress to other parts of the column body, thereby avoiding stress concentration in local areas. The combination of the reinforcing steel plate, X-shaped stiffener and reinforcing plate prevents the column from deforming during use, effectively avoiding the problem of internal stress and column deformation caused by external loads and temperature changes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a technical solution, including an installation plate 1 and four main steel plates 2 arranged in a circular pattern welded to the top surface of the installation plate 1. An end corner steel plate 3 is welded to the corners where the four main steel plates 2 meet. Multiple sets of stress relief units 4 are arranged in a uniform pattern on the inner wall of the four main steel plates 2.

[0020] Each stress relief unit 4 includes two symmetrically distributed connecting plates 41 installed on the main steel plate 2 and an arc-shaped elastic plate 42 installed between the two connecting plates 41. The inner arc concave surface of the arc-shaped elastic plate 42 is away from the corresponding main steel plate 2.

[0021] Specifically, the arc-shaped elastic plate 42 is made of high-elasticity steel, with its concave surface facing the inside of the box-type steel structure column. When the box-type steel structure column is subjected to external loads, it will deform and be stressed. At this time, the arc-shaped elastic plate 42 will bend elastically, absorb some of the stress, and transfer the stress to the connecting plate 41 and other parts of the column body, thereby avoiding stress concentration in local areas and ensuring the stability and safety of the column.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that three evenly distributed reinforcing steel plates 5 are welded between each of the two adjacent corner steel plates 3, and X-shaped reinforcing ribs 6 are welded between each of the two adjacent reinforcing steel plates 5.

[0023] Specifically, with the cooperation of the reinforcing steel plate 5 and the X-shaped reinforcing rib 6, the main steel plate 2 is reinforced to prevent deformation, thereby further reinforcing the box-type steel structure support and improving its stability and anti-deformation ability.

[0024] Further as Figure 1 As shown, it is worth noting that a reinforcing plate 7 is welded between the top surface of the mounting plate 1 and the outer surface of each end angle steel plate 3.

[0025] Specifically, a reinforcing plate 7 is installed between the mounting plate 1 and the end angle steel plate 3 to improve the stability of the connection between the mounting plate 1 and the overall box-type steel structure support.

[0026] Further as Figure 3 As shown, it is worth noting that each arc-shaped elastic plate 42 is spaced apart from the corresponding main steel plate 2.

[0027] Specifically, each arc-shaped elastic plate 42 is spaced apart from the corresponding main steel plate 2 to provide space for the deformation of the arc-shaped elastic plate 42.

[0028] In summary: During use, when the box-type steel structure support is subjected to external loads, it will deform and experience stress. At this time, the arc-shaped elastic plate 42 will undergo elastic bending, absorbing part of the stress and transferring it to the connecting plate 41 and other parts of the support body, thereby preventing stress concentration in local areas. When there are large temperature changes, due to the thermal expansion and contraction of steel, stress will also be generated inside the support. The arc-shaped elastic plate 42 can also release these stresses through elastic deformation. Combined with the reinforcing steel plate 5, X-shaped reinforcing ribs 6, and reinforcing plate 7 set on the outside of the support, the support is prevented from deforming during use, ensuring the stability and safety of the support. This effectively avoids the problem of internal stress causing deformation of the box-type steel structure support when it is affected by external loads, temperature changes, welding, and other factors.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
