摘要

建筑幕墙外保温系统火灾事故频发

火灾危险性大

其防火安全性能已成为社会关注的焦点问题。利用FDS软件模拟了不同宽度、不同位置防火封堵下幕墙保温系统的火灾蔓延情况

讨论了防火措施抑制火焰传播的有效性和可行性

并提出了最优的防火构造组合。模拟结果表明

当防火封堵的宽度达到100mm

防火隔离带的宽度为300mm时

系统已具有较好的防火性能。可将其设为防火构造设计的基准参数

供综合考虑实际工程的应用性和经济性参考。

Abstract

This paper simulates the fire prevention performance of external insulation system with curtain wall based on FDS method.The effect to control flame spread of fire-barrier belt and fire separating element with different widths is discussed.The characteristics of temperature distribution on interior

exterior and intermediate cavity of external insulation system are analyzed and the variability of heat release rate is found.The results prove that fire-barrier belt and fire separating element could effectively inhibit flame spread and growth.The fire prevention performance of external insulation system is enhanced with increasing of width.When the width of fire separating element is 100 mm and fire-barrier belt width is 300 mm

the whole external insulation system has high fire prevention performance

which can be set as basic parameters for the design of fire protection construction considering the applicability and economical efficiency of actual engineering.
