Description

Technical Field

[0001] This utility model relates to the field of steel structures, and in particular to a steel structure cross column that prevents deformation. Background Technology

[0002] Steel structures are structures mainly composed of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Cross columns are cross-shaped welded building materials based on steel structures. They are lightweight and have good seismic performance. At present, more and more high-rise buildings use steel structures as their main structure, and cross columns are widely used in high-rise buildings.

[0003] Steel cross-shaped columns, due to their unique cross-shaped structure, are widely used in construction projects, especially in large-span, high-rise buildings where structural load-bearing capacity is crucial. However, traditional steel cross-shaped columns are prone to problems such as localized deformation and poor overall stability under load. Due to unreasonable structural design, stress concentration easily occurs at the connection between H-shaped and T-shaped steel columns under large axial pressure, bending moment, or shear force, leading to weld cracking, component deformation, and compromised safety. Therefore, we propose a deformation-preventing steel cross-shaped column to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a steel structure cross column that prevents deformation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A deformation-resistant steel cross-shaped column includes a cross-shaped column body composed of an H-shaped steel column and two T-shaped steel columns. The outer surface of each T-shaped steel column is welded to the outer surface of the H-shaped steel column. Multiple internal reinforcing plates are fixedly connected to the outer surface of each T-shaped steel column. The end of each internal reinforcing plate away from the T-shaped steel column is fixedly connected to the outer surface of the H-shaped steel column. A reinforcing frame is fixedly connected to the outer surface of each internal reinforcing plate. The outer surface of each reinforcing frame is fixedly connected to the outer surfaces of both the H-shaped steel column and the T-shaped steel column.

[0007] In a further embodiment, each of the T-shaped steel columns has multiple angular stiffening ribs fixedly connected to its outer surface, and each group of angular stiffening ribs has a connecting strip fixedly connected to its outer surface.

[0008] In a further embodiment, each of the T-shaped steel columns has multiple external connecting rods fixedly connected to its outer surface, and the outer surface of each external connecting rod is fixedly connected to the outer surface of the internal reinforcing plate. Each group of external connecting rods has long connecting bars fixedly connected to its outer surface.

[0009] In a further embodiment, a connecting plate with an opening is fixedly connected to the outer surface of the cross-shaped column, and a plurality of equally spaced studs are fixedly connected to the outer surface of the cross-shaped column.

[0010] In a further embodiment, the outer surface of the cross-shaped column is fixedly connected with a plurality of perforated connecting plates.

[0011] In a further embodiment, one end of the H-shaped steel column and one end of the two T-shaped steel columns are fixedly connected to a plurality of external reinforcing plates, and the outer surfaces of the plurality of external reinforcing plates are fixedly connected to a cross protrusion, and the outer surface of the cross protrusion is provided with a plurality of lifting ports.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device effectively disperses stress and enhances the overall rigidity of the cross-shaped column through multiple reinforcement structures such as internal reinforcing plates, reinforcing frames, and angular stiffening ribs. Compared with traditional cross-shaped columns, its resistance to deformation is increased by more than 90%, allowing it to withstand greater loads without deformation. Moreover, the external reinforcing plates and cross protrusions enhance the strength of the column ends. The hoisting port facilitates installation without affecting the structural strength. Connection structures such as studs, connecting plates with openings, and connecting plates with holes ensure a firm connection between the cross-shaped column and other components, ensuring the overall stability of the building structure, reducing stress concentration and local deformation, reducing component fatigue damage, effectively dispersing stress, preventing column deformation, and greatly extending the service life of the steel structure cross-shaped column, thus reducing later maintenance costs.

[0021] 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.

[0022] Please see Figure 1-4In this utility model, a steel structure cross column for preventing deformation includes a cross column body 1, which is composed of an H-shaped steel column 2 and two T-shaped steel columns 3. The outer surface of each T-shaped steel column 3 is welded to the outer surface of the H-shaped steel column 2. Multiple internal reinforcing plates 10 are fixedly connected to the outer surface of each T-shaped steel column 3. The end of each internal reinforcing plate 10 away from the T-shaped steel column 3 is fixedly connected to the outer surface of the H-shaped steel column 2. A reinforcing frame 11 is fixedly connected to the outer surface of each internal reinforcing plate 10. The outer surfaces of each reinforcing frame 11 are fixedly connected to the outer surfaces of the H-shaped steel column 2 and the T-shaped steel column 3. The H-shaped steel column 2 and the T-shaped steel column 3 are welded to form a cross-shaped column body. The internal reinforcing plate 10 connects the H-shaped steel column 2 and the T-shaped steel column 3 to enhance the strength of the connection. The reinforcing frame 11 further strengthens the structure, forming a stable spatial structure, effectively dispersing stress and preventing column deformation. After the H-shaped steel column 2 and the T-shaped steel column 3 are welded together, the internal reinforcing plate 10 and the reinforcing frame 11 are installed, effectively ensuring the safety of the building structure.

[0023] Each T-shaped steel column 3 has multiple angular stiffening ribs 14 fixedly connected to its outer surface. Each set of angular stiffening ribs 14 has a connecting strip 15 fixedly connected to its outer surface. The angular stiffening ribs 14 increase the local stiffness of the T-shaped steel column 3 and prevent local buckling of the T-shaped steel column 3 under stress. The connecting strip 15 connects multiple sets of angular stiffening ribs 14 into a whole, enhances the synergistic effect, and further improves the stability of the cross column. Each T-shaped steel column 3 has multiple external connecting rods 12 fixedly connected to its outer surface. The outer surface of each external connecting rod 12 is fixedly connected to the outer surface of the internal hoop plate 10. Each set of external connecting rods 12 has a long connecting bar 13 fixedly connected to its outer surface. The external connecting rods 12 and the long connecting bar 13 tightly connect the internal hoop plate 10 and the T-shaped steel column 3 to form a spatial force system, which enhances the overall torsional and bending resistance of the cross column and keeps the column stable under complex stress conditions.

[0024] The outer surface of the cross column 1 is fixedly connected with a connecting plate 7 with openings, and multiple equidistant studs 9 are also fixedly connected to the outer surface of the cross column 1. The connecting plate 7 with openings facilitates quick connection of the cross column with other components via bolts or welding. The studs 9 increase the bond strength between the cross column and materials such as concrete, enabling the steel structure to work in tandem with other structures, improving the overall integrity of the building structure, and effectively enhancing the overall performance of the building structure. The outer surface of the cross column 1 is fixedly connected with multiple connecting plates 8 with holes, providing more connection nodes. According to actual engineering needs, it can be connected with different types of components, increasing the flexibility of the cross column application. One end of the H-shaped steel column 2 and one end of the two T-shaped steel columns 3 are jointly fixedly connected with multiple external reinforcing plates 4. The outer surfaces of the multiple external reinforcing plates 4 are jointly fixedly connected with cross protrusions 5. The outer surfaces of the cross protrusions 5 have multiple lifting ports 6. The external reinforcing plates 4 and cross protrusions 5 enhance the strength and rigidity of the ends of the cross column 1, improving the column's load-bearing capacity. The lifting ports 6 facilitate the lifting and positioning of the cross column, improving construction efficiency without affecting the structural strength of the column.

[0025] The working principle of this utility model is as follows:

[0026] The cross-shaped column 1 is welded from H-shaped steel columns 2 and T-shaped steel columns 3 to form a basic frame. An internal stiffening plate 10 connects one end to the T-shaped steel column 3 and the other end to the H-shaped steel column 2. When the cross-shaped column bears a load, the stress generated by the load is transferred through the T-shaped steel column 3 to the internal stiffening plate 10, and then dispersed by the internal stiffening plate 10 to the H-shaped steel column 2, preventing stress concentration at the weld joint. The reinforcing frame 11 further strengthens the connection, forming a stable triangular load-bearing structure together with the internal stiffening plate 10. Angle-shaped stiffening ribs 1... 4. To increase the local stiffness of the T-shaped steel column 3 and prevent it from buckling under stress, the connecting strip 15 connects multiple sets of angular stiffening ribs 14, so that they work together to resist external forces. The outer connecting rod 12 and the long connecting bar 13 connect the internal reinforcing plate 10 and the T-shaped steel column 3 to form a spatial force system, which evenly distributes the stress to the entire cross column 1 and improves the overall stiffness. For example, in the construction of high-rise office buildings, when the building is subjected to wind or gravity loads, the stress is dispersed through this structure, so that the column remains stable.
