Fireproof building material for steel structure buildings

Abstract

The invention discloses a fireproof building material for steel structure buildings, which has low construction intensity, simple, convenient, rapid and flexible construction, easy repair and good decoration property. The fireproof building material for steel structure buildings comprises a fireproof base material (1), a fireproof coating layer (2) is coated on the upper surface of the fireproof base material (1), an adhesive layer (3) is arranged on the lower surface of the fireproof base material (1), and a protective layer (4) is coated on the bottom surface of the adhesive layer (3). The invention can be widely applied to the field of fireproofing of the steel structures.

Description

technical field [0001] The invention relates to a fireproof building material for steel structure buildings. Background technique [0002] Steel structure is one of the main building structures. Because of its high strength, light weight, easy manufacture, fast construction speed, good plasticity and toughness, it is widely used in industrial and civil buildings. Steel is a non-combustible building material, which has the characteristics of earthquake resistance, bending resistance and so on. In practical applications, steel can not only increase the load capacity of buildings relatively, but also meet the needs of architectural design aesthetics, and avoid the defects of concrete and other building materials that cannot be bent and stretched. Therefore, steel structures are favored by the construction industry. Single-storey, multi-storey, skyscrapers, factories, warehouses, waiting rooms, waiting halls, etc. are all made of steel. However, as a building material, steel h...

AI Technical Summary

Problems solved by technology

The fireproof coating of steel structure is painted by brushing method, and its construction strength is high. It needs to be painted after the steel structure is installed on site, and it needs a certain period of time to cure. The construction time is long, and the thickness of the coating is difficult to effectively control. The thickness is uneven, and the decoration of the steel structure surface is poor; the spraying method is used to paint the steel structure fireproof coating, which also needs to be painted after the steel structure is installed on site, and it takes a certain period of time to cure. The construction time is long, and the steel structure The decoration of the surface is poor, the color is single, and it is difficult to adjust the color; if it is painted before the installation of the steel structure, the fireproof coating is easy to be damaged during the on-site installation of the steel structure, and it needs to be repainted after construction. troublesome, labor intensive
