外墙外保温防火技术现状及其问题探讨

本文分析了当前国内外外墙外保温系统防火技术与标准现状,并针对国内建筑特点和外墙外保温系统存在的巨大安全隐患提出:1)开发高耐火性外墙外保温系统;2)建立完善的外墙外保温系统和材料的防火试验方法及标准;3)制订有效并切实可行的外墙外保温防火等级评价和适用建筑范围的标准与规范。以上所讨论内容用于提高当前和今后中国建筑外墙外保温系统的防火安全性,提高国内外墙外保温系统的防火技术水平。

Discussion on Fire-proof Technologies and Problems of Outer-wall External Thermal Insulation System

The paper described the current fire-proof technologies in China and foreign countries,and provided some fire-proof methods for outer-wall external thermal insulation system according to the building characteristics.These methods included three aspects,to develop well fire-proof outer-wall external thermal insulation system,to set up the fire-proof tests and standards for outer-wall external thermal insulation system,and to set up the effective and feasible fire-proof grades for outer-wall external thermal insulation system.These above methods will improve the domestic and foreign fire-proof safety and technologies for outer-wall external thermal insulation system.
