[0002] High-strength steel components refer to structural parts made of high-strength steel. These steels usually have high yield strength and tensile strength and can withstand large loads and deformations.

[0019] A high-strength steel member, as shown in FIGS. 1 to 3, includes a steel body 1, and the outer surface of the steel body 1

[0020] is fixedly installed with a plurality of reinforcing ribs 2. The steel body 1 is arranged in a square frame shape, and the inner cavity of the steel body 1 is fixedly installed

[0021]

[0022] It is equipped with several supporting steel plates 3, and the supporting steel plates 3 are arranged in a herringbone shape. On both the left and right sides of the inner cavity of the steel body 1, several supporting columns 4 are fixedly installed. On both the left and right parts of the steel body 1, two fixing plates 5 are fixedly installed. The reinforcing rib 2 and the fixing plate 5 maintain a parallel positional relationship. By arranging several connected herringbone supporting steel plates 3 inside the steel body 1

[0023] The herringbone supporting steel plates 3 form a stable internal framework, providing

[0024] extra support for the steel body 1 and increasing its ability to resist buckling deformation. The herringbone supporting steel plates 3 can effectively

[0025] disperse the axial pressure and bending moment inside the steel body 1, making the stress distribution more uniform and reducing the phenomenon of local stress concentration. By arranging the supporting columns 4 on both the left and right sides of the inner cavity of the steel body 1, the overall stiffness of the steel body 1 can be significantly enhanced, making it less likely to deform when subjected to external forces. The supporting columns 4 can also provide extra support in the local stress area to prevent buckling instability caused by excessive local stress. By arranging the reinforcing rib 2 on the outer surface of the steel body 1, the strength and stiffness of the outer surface of the component can be increased, further improving its ability to resist buckling deformation.

[0026] Two through holes 6 are opened at the right end of the fixing plate 5, and positioning bolts 7 are arranged inside the through holes 6. The fixing plate 5

[0027] As a connecting piece, it can firmly connect the steel body 1 with other components or the foundation, forming

[0028] a stable overall structure. It tightly fixes each part together through the positioning bolts 7 to ensure the stability and integrity of the structure.

[0029] Working principle: By arranging several connected herringbone supporting steel plates 3 inside the steel body 1, the herringbone supporting steel plates 3 form a stable internal framework, providing extra support for the steel body 1 and increasing

[0030] its ability to resist buckling deformation. The herringbone supporting steel plates 3 can effectively disperse the axial pressure and bending moment inside the steel body 1, making the stress distribution more uniform and reducing the phenomenon of local stress concentration. By arranging the supporting columns 4 on both the left and right sides of the inner cavity of the steel body 1, the overall stiffness of the steel body 1 can be significantly enhanced, making it

[0031] less likely to deform when subjected to external forces. The supporting columns 4 can also provide extra

[0032] To provide support and prevent buckling instability caused by excessive local stress, reinforcing ribs 2 are provided on the outer surface of the steel body 1 to increase the strength and rigidity of the outer surface of the component and further improve its ability to resist buckling deformation. In summary, by providing a number of connected herringbone support steel plates 3 inside the steel body 1, and providing support columns 4 on the left and right sides of the inner cavity of the steel body 1, and providing reinforcing ribs 2 on the outer surface of the steel body 1, these measures can significantly improve the buckling stability and anti-instability ability of the hollow steel component when subjected to axial pressure, bending moment and local force.
