建筑外墙外保温材料防火安全的选型设计探讨

摘要

近年来,我国因建筑外墙外保温材料防火安全问题而导致特大火灾事故频发,尤其是上海胶州路教师公寓火灾、沈阳皇朝万鑫大厦火灾和北京央视大楼火灾,造成重大人员伤亡和财产损失,使得建筑外墙外保温材料防火安全成为人们关注的焦点.该文针对目前建筑外墙外保温材料选型设计中不注重防火安全的实际问题,分析了各种建筑外墙外保温材料防火性能,探讨其不同的使用局限性和优缺点,为建筑外墙外保温材料的选型设计提供参考.%In recent years the thermal insulation materials covering on the exterior wall for building fire safety problems caused the serious fire accidents, especially in the teacher apartment fire at Jiaozhou Road in Shanghai, the Dynasty wan Xin building fire in Shenyang and the CCTV building fire in Beijing, which caused the heavy casualties and the property losses, Therefore, the fire safety of the thermal insulation materials covering on the exterior wall has been a focus of attention.For solving the problem of the current moterials selection not paying attention to fire safety design, This paper analyzes the various fire performances of thermal insulation material covering on exterior wall, and their advantages and disadvantages, as a reference of selecting the thermal insulation material in the fire safety design.
