DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. The present utility model is described in detail using structure schematic diagrams, etc. The schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein.

[0026] Please refer to Figures 1 to 4 , a high-strength torsion-resistant steel column, which includes a column top plate 1, a column body 2, and a column bottom plate 6 connected in sequence from top to bottom. The column body 2 includes a first vertical plate 2a and a second vertical plate 2b that are parallel to each other. The first vertical plate 2a and the second vertical plate 2b are connected by a third vertical plate 2c. The third vertical plate 2c is perpendicular to the first vertical plate 2a and the second vertical plate 2b. Therefore, the cross-section of the column body 2 is in an "H" shape, with a reasonable cross-sectional shape, which can give full play to the mechanical properties of the steel, withstand greater pressure, tension, and bending moment, and provide reliable support for the building structure. The column top plate 1 and the column bottom plate 6 are parallel to each other and both are provided with assembly holes that penetrate up and down.

[0027] In order to improve the resistance to torque, support ribs 2d are provided on the opposite surfaces of the first vertical plate 2a and the second vertical plate 2b at relative positions. The support ribs 2d are connected to the first vertical plate 2a and the second vertical plate 2b by welding. The welding process undergoes strict quality control to ensure firm and reliable connection. All the support ribs 2d are at equal distances from the third vertical plate 2c. The support ribs 2d provided on the first vertical plate 2a and the support ribs 2d provided on the second vertical plate 2b are connected by a number of adjustable diagonal bracing bars 3. Longitudinal grooves 2d-1 are provided on the support ribs 2d. The diagonal bracing bars 3 are connected to the longitudinal grooves 2d-1 by high-strength bolts. The diagonal bracing bars 3 completed in connection with the longitudinal grooves 2d-1 are in contact with both the first vertical plate 2a and the second vertical plate 2b. The inclination directions of adjacent two diagonal bracing bars 3 are opposite, and the included angle α is 45° - 75°. The bolt connection method makes the diagonal bracing bars 3 convenient for installation and disassembly. The setting density of the diagonal bracing bars 3 can be adjusted according to the requirements of torsional strength, based on the convenient movement of the longitudinal grooves 2d-1.

[0028] At the same time, diagonal bracing plates 4 are provided between the support ribs 2d and the third vertical plate 2c. On each of the two surfaces of the diagonal bracing plates 4 in contact with the third vertical plate 2c, a pressing plate 5 is provided. The two pressing plates 5 are connected by high-strength bolts passing through the third vertical plate 2c. A space for one end of the diagonal bracing plate 4 to be inserted is provided between the pressing plate 5 and the third vertical plate 2c. The cross-section of the pressing plate 5 is an isosceles trapezoid. One pressing plate 5 is connected to two symmetrically arranged diagonal bracing plates 4. By tightening the bolts, the two pressing plates 5 approach each other and tightly press one end of the diagonal bracing plate 4. The other end of the diagonal bracing plate 4 tightly abuts the connection angle between the support rib 2d and the column body 2. The diagonal bracing plates 4 and the column body 2 form a plurality of stable triangular structures.

[0029] All parts of the high-strength torsion-resistant steel column of the present utility model cooperate with each other. The arrangement of the supporting ribs 2d, the diagonal bracing bars 3 and the diagonal bracing plates 4 greatly improves the strength and torsion resistance of the steel column, enabling it to withstand greater external forces, ensuring the stability and reliability of the steel column in practical applications. Anti-rust and corrosion-resistant coatings are applied to the surfaces of all components of the steel column. By comprehensively applying the above technical measures, the torsion resistance and service life of the steel column can be significantly improved, effectively solving the deficiency of the traditional steel column in torsional resistance and ensuring the safety and stability of the structure.

[0030] In actual building construction, according to the requirements of the building design, select high-strength torsion-resistant steel columns of appropriate specifications. After transporting the steel columns to the construction site, connect them to other building structure components through connectors. During the connection process, strictly operate in accordance with the installation process requirements to ensure firm and reliable connection. During the use of the steel column, regularly inspect and maintain it, and promptly discover and handle possible problems to ensure the performance and safety of the steel column.

[0031] In summary, the high-strength torsion-resistant steel column of the present invention has the advantages of high strength, good torsion resistance, corrosion resistance, and convenient installation, can meet the high-performance requirements of modern buildings for steel columns, and has broad market application prospects.

[0032] As mentioned above, it is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be pointed out that for those skilled in the art, without departing from the concept of the present utility model, changes, modifications or additions should all fall within the protection scope of the present utility model.
