Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, and in particular to a box-type column. Background Technology
[0002] Traditional box columns are typically composed of 4 plates (or 5 plates including an internal partition). These 4 plates are welded vertically in pairs to form a box column, meaning that the formed box column has 4 main welds. These 4 main welds are designed in two forms, full penetration bevel and partial penetration bevel, depending on the strength requirements.
[0003] Because traditional box-type columns have many welds, a large amount of welding materials are required. During the welding process, a large amount of manpower is needed to support this work, resulting in a significant waste of welding materials and manpower. Moreover, the welds are all located at the corners of the structure. At the corners, defects such as gaps and burrs are easily formed, which accelerates the corrosion of local metals and may even form pinholes and cracks. This type of corrosion is localized corrosion, which affects product quality and product life. Utility Model Content
[0004] In view of the above-mentioned shortcomings, this utility model provides a box-type column, which can greatly reduce the manufacturing process, improve production efficiency, reduce welding difficulty, increase the service life of components, and also enhance structural strength and aesthetics. It has a simple structure, is easy to manufacture and process, and has low cost.
[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:
[0006] A box-shaped column includes a first bent component, a second bent component, a first main weld, and a second main weld. The first bent component and the second bent component are spliced together. The first main weld is located at the splice of the first bent component and the second bent component, and the second main weld is located at another splice of the first bent component and the second bent component.
[0007] According to one aspect of this utility model, both the first bending member and the second bending member are U-shaped.
[0008] According to one aspect of the present invention, both ends of the first bending member and the second bending member are vertically bent, and the bending points are arc-shaped transitions.
[0009] According to one aspect of this utility model, the first bending member and the second bending member have the same structure and are symmetrically spliced together.
[0010] According to one aspect of the present invention, it also includes a transverse partition, which is welded between the first bent member and the second bent member.
[0011] According to one aspect of this utility model, the first bent piece and the second bent piece are joined together to form a rectangle, and the transverse partition is a square plate.
[0012] According to one aspect of this utility model, the first bending member, the second bending member, and the transverse partition are all made of steel.
[0013] The advantages of this invention are as follows: By dividing the traditional box-shaped column into two parts, directional bending after cutting, and then welding, the manufacturing process of the box-shaped column can be greatly reduced. The number of main weld seams has been reduced from four to two, improving production efficiency. Furthermore, the weld seam location has been adjusted from a corrosion-prone corner point to the middle of the structure, reducing welding difficulty, increasing the service life of the component, and enhancing structural strength and aesthetics. This invention has a simple structure, is easy to manufacture and process, and has low cost. Attached Figure Description

[0022] Example 1
[0023] like Figure 2 - Figure 4 As shown, a novel box-type column includes a first bent component 1, a second bent component 2, a first main weld 3, and a second main weld 4. Both the first bent component 1 and the second bent component 2 are U-shaped steel plates, with both ends bent vertically and the bends forming an arc transition. This design, compared to structures where two plates are vertically welded to the ends of a single plate, results in a more aesthetically pleasing structure while maintaining structural strength, avoiding the problem of relatively low structural strength due to stress concentration at fillet welds. After aligning and splicing the first bent component 1 and the second bent component 2, a submerged arc welding machine is used for welding, thus forming the first main weld 3 and the second main weld 4 at the splice of the first bent component 1 and the second bent component 2, ultimately welding them into a box-shaped column. This method, compared to a structure using four plates welded perpendicularly in pairs with four main weld seams, reduces the number of weld seams and welding materials, lowers costs, simplifies the manufacturing process, and allows welding at the structural corners to be replaced with planar welding, reducing welding difficulty, ensuring product quality and lifespan, and also making the structure more aesthetically pleasing. This invention can increase the production output of such components and improve product quality by changing the weld seam positions, thus achieving cost reduction and efficiency improvement for enterprises.
[0024] In this embodiment, the first bent component 1 and the second bent component 2 have identical structures and are symmetrically spliced together. Both are formed by bending a flat plate at both ends using a CNC plate bending machine. After splicing, the first bent component 1 and the second bent component 2 form a rectangle, or in other words, a cuboid steel column.
[0025] In this embodiment, the box-shaped column also includes a diaphragm 5, which is welded between the first bent member 1 and the second bent member 2, or in other words, the diaphragm 5 is welded inside the cuboid steel column formed by the splicing of the first bent member 1 and the second bent member 2. The diaphragm 5 is a square steel plate, and its structural shape is adapted to the structural shape of the spliced first bent member 1 and the second bent member 2; the diaphragm 5 is used to enhance the structural stability.
[0026] The beneficial effects of this embodiment are as follows: By dividing the traditional box-shaped column into two, cutting it into blanks, bending it in a specific direction, and then welding it together, the manufacturing process of the box-shaped column can be greatly reduced. The number of main weld seams has been reduced from four to two, improving production efficiency. Furthermore, the weld seam location has been adjusted from a corrosion-prone corner point to the middle of the structure, reducing welding difficulty, increasing the service life of the component, and enhancing structural strength and aesthetics. This invention has a simple structure, is easy to manufacture and process, and has low cost.
[0027] Example 2
[0028] This embodiment provides a manufacturing process for a box-shaped column, including the following steps:
[0029] The steel plate is cut to a fixed length using a flame cutting machine or similar equipment to form blanks for the first bending part 1 and the second bending part 2.
[0030] The bending process involves using a CNC sheet metal bending machine to bend the two ends of the blanks for the first bending part 1 and the second bending part 2 in a directional manner, thereby forming the first bending part 1 and the second bending part 2.
[0031] Assemble by aligning and joining the two bent pieces, the first bent piece 1 and the second bent piece 2.
[0032] Welding was performed at the joint of the first bent part 1 and the second bent part 2 using a submerged arc automatic welding machine.
[0033] Box-shaped column products were obtained.
[0034] The beneficial effects of this embodiment are as follows: By dividing the traditional box-shaped column into two, cutting it into blanks, bending it in a specific direction, and then welding it together, the manufacturing process of the box-shaped column can be greatly reduced. The number of main weld seams has been reduced from four to two, improving production efficiency. Furthermore, the weld seam location has been adjusted from a corrosion-prone corner point to the middle of the structure, reducing welding difficulty, increasing the service life of the component, and enhancing structural strength and aesthetics. This invention has a simple structure, is easy to manufacture and process, and has low cost.
