Description

Technical Field

[0001] This utility model relates to a building construction structure, and in particular to a fireproof steel column construction structure suitable for modular buildings. Background Technology

[0002] Steel columns are a common structural element in building construction. Steel column structures typically require fireproofing during construction. Current methods generally involve coating the outer surface of the steel columns with fire-retardant paint. However, this method has drawbacks such as poor fire resistance, easy peeling of the fire-retardant paint, and insufficient stability of fire resistance, making it unsuitable for high fire performance requirements. Furthermore, modular buildings often require the fireproofing of steel columns to be completed in the factory. Transporting the modular units to the construction site makes it inconvenient to apply fire-retardant paint, affecting construction efficiency and quality.

[0003] Therefore, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content
