Description

Technical Field

[0001] The utility model relates to the technical field of steel components, in particular to a steel component outer-wrapped with a NALC fireproof board. Background Art

[0002] Steel components refer to steel structure composite components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected through connectors. The steel component system has the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Especially with the development of the national economy, the advantages of the seismic performance of the steel structure system and the advantages of flexible space are gradually being applied in residential projects.

[0003] The steel structure itself has poor fire resistance, so fire prevention measures must be taken. However, the traditional fire prevention method for steel components is to spray fire retardant coating on the outside and then cover the gypsum board with the decorative layer. This method also requires the external board processing during the later decorative layer construction. At the same time, after the fire retardant coating is sprayed on the steel component, the surface of the steel component is rough, and the fire retardant coating has poor adhesion performance. Interface treatment and repair are required, resulting in high construction costs and long construction periods. In summary, the existing steel components still have the following problems:
