Description

High-strength, non-deformable metal steel structure Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to high-strength, non-deformable metal steel structures. Background Technology

[0002] A cruciform steel structure is a type of steel structure with a cruciform cross-section, welded from multiple steel plates. It typically consists of a web and flanges, and its symmetrical cross-section provides excellent torsional resistance and bidirectional load-bearing capacity. In building construction, cruciform steel structures are commonly used in steel frame beam-column joints and wind-resistant columns in high-rise buildings, effectively transferring bidirectional bending moments and shear forces. Due to its large radius of gyration and rational material distribution, it can reduce steel consumption while maintaining strength, offering both economic and mechanical performance advantages. With the development of steel structure technology, cruciform steel structures have further improved structural stability and construction efficiency through optimized welding processes and the use of high-performance steel, demonstrating broad application prospects in large-span spatial structures and heavy industrial plants.

[0003] In existing technologies, the main body of the cross-shaped steel structure is prone to torsion or local buckling deformation when subjected to complex loads. Moreover, traditional reinforced structures are mostly designed with fixed dimensions, making it difficult to quickly adapt to cross-shaped steel structures with different cross-sectional dimensions and flange widths, resulting in poor versatility. In view of this, we propose a high-strength, non-deformable metal steel structure. Summary of the Invention

[0004] The purpose of this invention is to provide a high-strength, non-deformable metal steel structure 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 high-strength, non-deformable metal steel structure includes a cross-shaped steel structure main body. A reinforcing structure is fitted on the outside of the steel structure main body. The reinforcing structure includes four fixing components respectively fixed to the flanges of the steel structure main body, support components installed on the left and right end faces of the fixing components, and an adjustment component disposed between two adjacent support components. The support component includes a base plate fixedly connected to the fixing components and a support seat fixed to the outside of the base plate. Two adjacent support seats are supported by the adjustment component.

[0007] Preferably, the fixing component includes a sleeve, and a cavity is formed on the rear end face of the sleeve, and the sleeve is fitted onto the flange of the steel structure body through the cavity;

[0008] In this configuration, the sleeve fits into the flange of the main steel structure through the sleeve cavity, which facilitates the quick positioning and installation of the fixing components and provides a stable connection foundation for the subsequent support components.

[0009] Preferably, a U-shaped connecting seat is fixed between the base plate and the support base, and the base plate and the support base form a 45° angle.

[0010] In this design, the U-shaped connector enhances the connection strength between the base plate and the support seat, and the 45° angle design allows the support seat to support the main steel structure at an oblique angle, optimizing the load transfer path and improving structural stability.

[0011] Preferably, the adjusting assembly includes a threaded rod passing through the support and a pair of adjusting nuts threaded onto the threaded rod;

[0012] Preferably, a sleeve hole is formed on the end face of the support base, and the end of the threaded rod passes through the sleeve hole;

[0013] Preferably, when the two adjusting nuts on the threaded rod are rotated to move towards the beginning and end of the threaded rod respectively, the two adjusting nuts can abut against the two adjacent support seats respectively;

[0014] Of these three settings, the spacing between adjacent support seats can be adjusted by rotating the adjusting nut, so that the reinforcing structure can be adapted to steel structure bodies of different sizes. At the same time, the adjusting nut forms a pre-tightening force after it abuts against the support seat, which enhances the overall connection rigidity of the structure.

[0015] Preferably, the outer end face of the support base is provided with an annular protruding ring, and a plurality of tightening bolts are threadedly connected to the periphery of the protruding ring. When the adjusting nut is tightened, the end of the tightening bolt can be made to abut against the outer surface of the adjusting nut by tightening the tightening bolt.

[0016] Preferably, the convex ring and the support base are integrally formed, and the axis of the clamping bolt is perpendicular to the axis of the threaded rod to form axial and circumferential fixed constraints.

[0017] In these two configurations, the convex ring provides the mounting base for the clamping bolt. After the clamping bolt is tightened, its end abuts against the outer surface of the adjusting nut, which can prevent the adjusting nut from loosening due to vibration and other factors. The integrally formed convex ring and the support seat have higher connection strength. The axis of the clamping bolt is perpendicular to the axis of the threaded rod, which can form a fixed constraint on the adjusting nut from two orthogonal directions, improving the reliability and deformation resistance of the reinforcement structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This high-strength, non-deformable metal steel structure, through the cooperation of fixing components, supporting components and adjusting components in the reinforcing structure, forms multi-angle support and constraint on the main body of the steel structure, thereby improving the overall resistance to deformation;

[0020] 2. This high-strength, non-deformable metal steel structure, through the threaded rod and adjusting nut set in the adjustment component, allows for flexible adjustment of the support spacing by rotating the adjusting nut to change its position on the threaded rod, enabling the reinforcement structure to adapt to cross-shaped steel structure main bodies of different sizes.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please refer to Figures 1-5. The high-strength, non-deformable metal steel structure includes a cross-shaped steel structure main body 100, with adjacent flanges of the cross-shaped steel structure main body 100 forming a 90° angle. A reinforcing structure 200 is fitted around the outer side of the steel structure main body 100. The reinforcing structure 200 includes four fixing components 210 respectively fixed to the flanges of the steel structure main body 100, support components 220 installed on the left and right end faces of the fixing components 210, and an adjusting component 230 disposed between two adjacent support components 220. The support component 220 includes a base plate 221 fixedly connected to the fixing components 210 and a support seat 222 fixed to the outside of the base plate 221. Two adjacent support seats 222 are supported by the adjusting component 230. The combination of the fixing components 210, support components 220, and adjusting component 230 forms a reinforced constraint structure surrounding the steel structure main body 100, providing support from multiple directions and improving the overall resistance to deformation.

[0031] As shown in Figures 1-3, in this invention, the fixing component 210 includes a sleeve 211. A cavity 212 is formed on the rear end face of the sleeve 211. The sleeve 211 is fitted onto the flange of the steel structure body 100 through the cavity 212. The sleeve 211 is fixedly connected to the flange of the steel structure body 100 using bolts, allowing the sleeve 211 to be fixed to flanges of the steel structure body 100 with different thicknesses. The sleeve 211, through the cavity 212, engages with the flange of the steel structure body 100, enabling rapid positioning of the fixing component 210. The bolt connection method can adapt to the installation requirements of flanges with different thicknesses, improving structural versatility.

[0032] As shown in Figures 1, 2, and 4, specifically, a U-shaped connecting seat 223 is fixed between the base plate 221 and the support seat 222, with the base plate 221 and the support seat 222 forming a 45° angle. The U-shaped connecting seat 223 enhances the connection strength between the base plate 221 and the support seat 222. The 45° angle design allows the support seat 222 to provide oblique support to the steel structure body 100, optimizing the force transmission path. Since the two adjacent flanges of the cross-shaped steel structure body 100 form a 90° angle, the outer end faces of the corresponding two support seats 222 are parallel and aligned, thereby ensuring that the adjustment assembly 230 can provide stable support for both.

[0033] As shown in Figures 1, 2, 4, and 5, the adjusting assembly 230 further includes a threaded rod 231 passing through the support base 222 and a pair of adjusting nuts 232 threadedly connected to the threaded rod 231. A sleeve hole 2221 is provided on the end face of the support base 222, and the end of the threaded rod 231 passes through the sleeve hole 2221. When the two adjusting nuts 232 on the threaded rod 231 are rotated to move towards the beginning and end ends of the threaded rod 231, the two adjusting nuts 232 can respectively abut against the two adjacent support bases 222. After the adjusting nut 232 abuts against the support base 222, the pressure of the threaded rod 231 can cause the two adjusting nuts 232 to support the corresponding support components 220 on the fixed component 210. When installed on steel structure main bodies 100 of different sizes, it is only necessary to adjust the position of the adjusting nut 232 on the threaded rod 231 and then rotate the adjusting nut 232 so that the two adjusting nuts 232 can still abut against the support components 220 at both ends, so that the reinforcing structure 200 can adapt to steel structure main bodies 100 of different sizes, and at the same time enhance the overall structure through pre-tightening force.

[0034] As shown in Figures 2 and 4, the outer end face of the support 222 is provided with an annular protruding ring 224. Several tightening bolts 2241 are threadedly connected to the periphery of the ring 224. When the adjusting nut 232 is tightened, the ends of the tightening bolts 2241 abut against the outer surface of the adjusting nut 232. The ring 224 and the support 222 are integrally formed. The axis of the tightening bolts 2241 is perpendicular to the axis of the threaded rod 231, forming axial and circumferential fixed constraints. The ring 224 and the tightening bolts 2241 cooperate to further lock the adjusting nut 232 in a direction perpendicular to the threaded rod 231 after the adjusting nut 232 is fixed in position, preventing it from loosening due to vibration or other factors, and ensuring the stability of the reinforcing structure 200.

[0035] In this embodiment, the high-strength, non-deformable metal steel structure is used in the following ways: First, four sleeves 211 are respectively fitted onto the flanges around the main body of the steel structure 100 through the sleeve cavity 212. Bolts are used to fix the sleeves 211 to the flanges, completing the installation of the fixing component 210. Then, according to the size of the main body of the steel structure 100, the distance between adjacent support seats 222 is adjusted by rotating the adjusting nut 232 on the threaded rod 231, so that the support component 220 is adapted to the flange width of the main body of the steel structure 100. Next, after the adjusting nut 232 is tightened against the support seat 222, the tightening bolt 2241 on the convex ring 224 is tightened, so that its end abuts against the outer surface of the adjusting nut 232, forming axial and circumferential fixed constraints. Finally, through the synergistic effect of the fixing component 210, the support component 220 and the adjusting component 230, the main body of the steel structure 100 is supported at multiple angles, improving its resistance to deformation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
