摘　　要：分析了国内外防火隔离带的设置要求,开展实体火灾试验,对比设置防火隔离带和未设置防火隔离带的外墙薄抹灰保温系统火灾蔓延情况,记录了不同位置的温度。结果表明,设置防火隔离带的试验中燃烧室上方5m处保温系统表面最高温度仅为300℃,防火隔离带能明显抑制初期火焰传播。The setting requirements of fire barrier in and abroad were analyzed,fire test was carried,fire spread of external thin plaster insulation system with and without fire barrier was compared and temperature at different sites were tested.The result showed with fire barrier the top surface temperature five meters up combustion room was 300 ℃ and fire barrier can significantly inhibit early fire spread.
