Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and more particularly to an acid-resistant and corrosion-resistant steel structure. Background Art

[0002] Support structures made of steel are light in weight and high in strength. They are widely used in various construction industries. Multiple groups of steel structures form a complete support structure to support the building structure and ensure its stability.

[0003] When existing steel structures are in use, adjacent steel structures are fixed by welding. Some steel structures need to be disassembled after use. Therefore, a detachable connection structure is used, which is generally fixed with bolts. However, when fixing with a bolt structure, multiple bolt parts need to be installed, which is cumbersome and inconvenient. In addition, after long-term use, the bolts are easily damaged and have problems, which may cause the connection position of the steel structure to loosen. Moreover, when manufacturing steel structures, a certain amount of acidic gas will be diffused in common factories, and when used outdoors, they may also come into contact with external acidic substances. Generally, steel structures are made of a relatively simple material. After contact with acidic substances, their surfaces are easily corroded, affecting the service life of the steel structure itself. In addition, some steel structures have corner structures in addition to straight shapes. The force-bearing structures at the corners are different, and the structural strength is weaker. After long-term use, they are prone to damage such as bending. Utility Model Content
