[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0020] Combination Figure 1-Figure 4A steel structure frame torsion-resistant steel member, comprising a steel structure outer tube 1 and a steel structure inner tube 2, wherein the steel structure outer tube 1 is fixedly connected to one end of the steel structure inner tube 2, and the steel structure outer tube 1 and the steel structure inner tube 2 are both hollow circular tube structures, and the hollow structure can reduce the dead weight of the steel structure outer tube 1 and the steel structure inner tube 2, and the steel structure outer tube 1 is sleeved with the adjacent steel structure inner tube 2, and a two-layer tube structure is provided, which can increase the overall thickness of the steel member and improve the strength of the steel member, and a support frame 3 is provided on the inner wall of the steel structure outer tube 1, and the support frame 3 is against the outer wall of the steel structure inner tube 2, and the inner wall of the steel structure outer tube 1 and the steel structure inner tube 2 adopt a non-direct contact structure, which is convenient for the installation of the steel structure inner tube 2, and at the same time, the support frame 3 is used to support the inner wall of the steel structure outer tube 1, which can improve the strength of the steel structure outer tube 1 and improve the torsion resistance of the steel structure outer tube 1.

[0021] In this embodiment, an annular rib plate 11 is provided on the inner wall of the steel structure outer tube 1 , and the annular rib plate 11 can improve the rigidity and stability of the structure.

[0022] In this embodiment, a slide groove 12 is provided on the inner wall of the outer steel structure tube 1 between the annular ribs 11 , and the slide groove 12 is movably connected to the support frame 3 , and the slide groove 12 is used for the support frame 3 to be telescopically movable.

[0023] When the cam 32 is in the unlock state, the cam 321 is locked and the locking cam 322 is locked.

[0024] In this embodiment, one end of the steel structure inner tube 2 away from the steel structure outer tube 1 is fixedly connected with a plug joint 21, and the plug joint 21 matches the inner diameter of the steel structure inner tube 2. During installation, the steel structure inner tube 2 is inserted into the adjacent steel structure outer tube 1, and the plug joint 21 is inserted into the adjacent steel structure inner tube 2. The plug joint 21 is connected with the steel structure inner tube 2 to fix the steel structure inner tube 2. A conical structure is provided at one end of the plug joint 21, which is convenient for aligning the position when installing the steel structure inner tube 2.

[0025] In this embodiment, an annular groove 22 is provided at one end of the steel structure inner tube 2 close to the steel structure outer tube 1. The annular groove 22 is used to install a high-strength bolt 23. The high-strength bolt 23 penetrates the annular groove 22 and is connected to the plug joint 21. The adjacent steel structure inner tube 2 is fixed by the high-strength bolt 23 to prevent the steel structure inner tube 2 from being separated from the steel structure outer tube 1. The annular groove 22 can hide the nut of the high-strength bolt 23. After the steel structure inner tube 2 is sleeved with the steel structure outer tube 1, the high-strength bolt 23 is hidden inside the steel structure outer tube 1, and the structure is stable.

[0026] Working process: During installation, one end of the steel component provided with the steel structure inner tube 2 is inserted into the steel structure outer tube 1 of the adjacent steel component, and the plug joint 21 gradually moves into the steel structure outer tube 1. After the steel structure inner tube 2 is inserted from the annular rib 11, it contacts the lower end of the support frame 3 and pushes the support frame 3 to shorten. The support frame 3 forms a support between the steel structure inner tube 2 and the steel structure outer tube 1. After the plug joint 21 is inserted into one end of the adjacent steel structure inner tube 2, a high-strength bolt 23 is driven into the annular groove 22 to lock the two adjacent steel components. When in use, the circular cross-section steel structure outer tube 1 has high torsional stiffness because its moment of inertia is large and can better resist torsion. At the same time, the steel structure inner tube 2, the steel structure outer tube 1 and the support frame 3 increase the wall thickness of the entire steel component, which can significantly improve the torsional resistance of the structure.

[0027] To sum up: the utility model is a steel structure frame torsion-resistant steel component, which divides the steel component into multiple sections, each section is connected by a key and fixed by a high-strength bolt 23 to disperse the torque. The steel structure outer tube 1 and the steel structure inner tube 2 both adopt a hollow structure with a circular cross-section, which can reduce the weight while maintaining sufficient torsion resistance. The steel structure outer tube 1 and the steel structure inner tube 2 are sleeved together, which is convenient for installation and increases the wall thickness, which can significantly improve the torsion resistance of the structure. An annular rib 11 and a support frame 3 are arranged inside the steel structure outer tube 1 to improve the rigidity and stability of the structure.
