Description

Technical Field

[0001] The invention relates to the technical field of fireproof steel structures, and in particular to a green building energy-saving fireproof steel structure and a preparation method thereof. Background Art

[0002] Green buildings refer to saving resources, protecting the environment, reducing pollution, and providing people with healthy, applicable, and efficient use spaces throughout their entire life cycle. Steel structures, as green buildings, are structures made of steel materials and are one of the main types of building structures. With the improvement of safety awareness, fireproof steel structures are becoming more and more popular. They have good high temperature resistance and reduce deformation caused by high temperatures.

[0003] In the prior art, although steel structure pillars have good supporting strength when used, the fire resistance of steel structures is extremely poor. When encountering a fire, they are easily deformed due to high temperature, which makes the building where the fire occurs easily collapse. Secondly, most of the existing steel structures are one-piece molded structures. During use, they have poor adjustability and cannot be adjusted in size according to the fire protection range.
