摘要
本文结合工作实际,综合考虑现有建筑外墙保温系统的保温材料,分析保温系统的火灾风险、防火安全系统影响因素,提出防火隔离带、挡火梁、防火分仓、满粘做法、增加保护层厚度等建筑构造措施,提高保温系统的防火性能,并对其防火分级、发展趋势提出自己的建议。
Considering insulation materials of the existing building＇s exterior wall system based on the practical working experience,fire risks of the insulation system and the factors influencing fire safety coefficient are analyzed.Some details of constructions to improve the performance of insulation systems are presented,including the fire barrier,the block firewall,the fire sub-compartment,full bonding practices,increasing the protective layer thickness.The fire rating and the trends of development are proposed.
