[0032] This utility model discloses a fatigue-resistant steel structure, such as Figs. 1 to 3 As shown, the structure includes a horizontal beam 1 and a vertical beam 2. Multiple reinforcing ribs 3 are installed between the horizontal beam 1 and the vertical beam 2 to enhance the connection strength between them. The reinforcing ribs 3 are L-shaped and can be thin sheets made of metal plates or composite materials, possessing high rigidity and strength. The number of reinforcing ribs 3 can be adjusted according to actual needs, generally no less than two, evenly distributed between the horizontal beam 1 and the vertical beam 2. For example, a 2mm thick high-strength steel plate can be used as the reinforcing rib 3, or a reinforcing rib 3 made of carbon fiber composite material can be selected to reduce weight while maintaining sufficient strength. A chamfer 6 is provided at the corner of the reinforcing rib 3, and a gap is provided between the chamfer 6 and the horizontal beam 1 and vertical beam 2. This gap is filled with shock-absorbing pads 7 to further improve fatigue resistance. For example, the chamfer 6 can be machined into an R5 rounded transition, with a gap width of approximately 5mm, filled with rubber shock-absorbing pads 7 to provide a buffering effect and reduce stress concentration.

[0033] The reinforcing rib plate 3 is provided with a fixing structure 4, which is used to fixedly connect one end of each reinforcing rib plate 3 to the cross beam 1 and the other end to the vertical beam 2, and mainly comprises a welding point and a bolt hole 41. The welding point is located at the contact surface of the two ends of the reinforcing rib plate 3 with the cross beam 1 and the vertical beam 2, and the reinforcing rib plate 3 is fixedly connected to the cross beam 1 and the vertical beam 2 by high-temperature molten metal. The bolt hole 41 penetrates through the reinforcing rib plate 3 and extends into the cross beam 1 and the vertical beam 2, and the reinforcing rib plate 3 is fixed to the cross beam 1 and the vertical beam 2 by the bolt hole 41. In this way, the reliability of the connection is ensured, and the disassembly and replacement are facilitated. For example, the bolt hole 41 with M10 specification, the bolt with a diameter of 10 mm and a length of 50 mm can be selected to ensure the stability of the connection. The double-fixed structure not only improves the stability of the connection, but also facilitates the later maintenance and replacement.

The elastic structure 5 mainly comprises a damping spring 51 and a spring hook 52. The damping spring 51 is made of high-elastic stainless steel material, and has a long service life and good rebound performance. The spring hook 52 is installed on the reinforcing rib plate 3 and is used to fix the damping spring 51, so that the damping spring 51 can effectively absorb vibration energy when subjected to stress and reduce the influence on the entire structure. In addition, a rubber sleeve can be wrapped around the damping spring 51 to further improve the damping effect.

[0035] The steel structure also comprises a rust-proof coating covering the outer surfaces of the cross beam 1, the vertical beam 2 and the reinforcing rib plate 3. The cross beam 1 and the vertical beam 2 each have a cavity 8 filled with a light foam material 9.

[0036] Working principle: The anti-fatigue steel structure designed by the utility model has stronger anti-fatigue capacity and higher safety by reasonably designing the shape and number of the reinforcing rib plate 3 and adopting multiple fixing modes and the elastic structure 5. Especially, the design of the damping spring 51 can effectively relieve stress when subjected to impact or continuous vibration and prolong the service life of the structure. In addition, the selection of the L-shaped metal plate and the high-strength alloy steel plate also ensures the overall rigidity and durability of the structure, so that the anti-fatigue performance is greatly improved without greatly changing the original structure.
