The components include beams, columns, trusses, etc. The surface of the components also needs to be rust-proofed and rust-proofed. The components are usually connected by welds, bolts or rivets. After the steel structure is built, it can have the high strength of steel. At the same time, compared with traditional building materials, it is light in weight and has less pressure on the ground foundation. At the same time, the construction speed is relatively fast. Relying on the development of modern technology, the highly industrialized production environment can better control the quality of steel structures and can be mass-produced.

[0004] The above document can install the steel structure according to the connection direction of the steel structure through various supporting components, which is convenient for customers to install the steel structure and improves the application range and ease of use of the device. However, the structural strength of the components in the above document is low, and the steel structure needs to be subjected to forces in various directions during use, and the above document lacks enhanced anti-torsion function. When subjected to non-downward pressure, the first reinforcing rod and the mounting clips at both ends of it are difficult to withstand structural deformation, which will affect the overall steel structure during long-term use. Therefore, it is difficult to withstand high-intensity use environments. Generally, the vertical support force of the steel structure is sufficient, and it has good resistance to unidirectional forces, but the stability of the overall structure needs to be improved.

[0005] In order to overcome the technical defects of the prior art, the present invention provides a corrosion-resistant and environmentally friendly steel structure, which can provide higher torsional resistance, better provide torsional support for the column components, and make the steel structure as a whole more stable. A protective component is added to the bottom connection of the steel structure, which can protect the connection structure of the column components during use and play a role in isolating corrosion.

[0006] The technical solution adopted by the present invention is: it includes a column member, and the column member is the main load-bearing member, which is arranged along the height direction of the building to play the role of transferring the load. When constructing the steel structure, it is necessary to first set a foundation on the ground of the target building, and choose whether to add embedded parts according to actual needs, and then connect and fix the bottom of the column member and the foundation. In this technical solution, H-shaped steel is used as the column member, and the column member includes an intermediate plate and external plates fixed on both sides of the intermediate plate. The upper side wall of the external plate is fixed with a diagonal brace by upper bolts. The diagonal brace is used to erect beam members, thereby facilitating the erection of a complete steel structure. A clamping mechanism is fixed on the side wall of the external plate below the diagonal brace, and the clamping mechanism is used to assist in fixing and supporting the diagonal brace. An anti-torsion component is provided between the external plates, and the anti-torsion component is used to expand the force range of the column support structure. In the actual use of the steel structure, the column member has a strong resistance to lateral forces. It has good bearing capacity and strong bending resistance, and only needs to specially consider the torsion bearing capacity of the column components. The traditional method is to connect and fix the diagonal rods between the columns, but the structure of the traditional columns is limited, and the fixed diagonal rods are difficult to support at a more appropriate angle. A connecting seat is provided on the lower side wall of the external plate and the anti-torsion component, and an inter-column support structure is provided between adjacent column components. The inter-column support components are fixed in position by the connecting seat.

The connecting seat body is fixed on the side wall of the outer plate. The connecting seat bodies located on both sides of the outer shell can enable the inter-column support structure to obtain a larger force arm when the column member is twisted, thereby better performing anti-torsion support.

Moreover, compared with traditional steel structures, a protective component is added to the bottom connection of the steel structure, which can protect the connection structure of the column components during use and play a role in isolating corrosion.

[0016] When the steel structure is in use, it is usually corroded by liquid intrusion, and the protective component can provide special atmosphere anti-corrosion protection for the connection to prevent the connection structure from being damaged. The ground foundation is made in advance, and embedded parts are set according to needs. Then the column member is suspended on the ground foundation for normal installation. In the present invention, a cover is used to cover the column member and the ground foundation, which first has an isolation effect and does not affect the structure of the column member itself. The high-pressure storage device can isolate the steel structure from gases that do not react with the steel structure or substances that can flow, thereby achieving an anti-corrosion effect. During use, it is necessary to regularly check the filling condition and the working status of the high-pressure storage device, thereby achieving long-term protection. The effect is that when the column component generates twisting, the anti-torsion component located on the upper part of the column component can first stabilize the component structure and reduce the influence of the twisting on the top of the column component, and then transmit the force to the inter-column support structure through the connecting seat on the outer shell. The inter-column support structure includes an end plate component that is fitted with the combining plate, and a stabilizing arm is fixed between the end plates. The stabilizing arm extends from the top of the column component to the bottom of another column component. The stabilizing arm is X-shaped, and a single stabilizing arm is composed of three mutually parallel partitions. In this way, the structural strength of the inter-column support structure can be improved. The inter-column support structure adopts a traditional cross shape to connect the column components on both sides, and the use of multiple parallel partitions on the stabilizing arm can further improve the structural strength.
