耐火窗的性能及存在的问题与建议

Performance and problems of the fire-proof windows and suggestions

近年来外墙外保温火灾事故频繁发生,给国家和人民带来了巨大的损失。2015年5月1日,我国实施了GB 50016—2014《建筑设计防火规范》,对不同类型、不同高度建筑保温材料的燃烧性能提出严格要求,并对建筑外窗的耐火完整性做出了严格规定。主要介绍耐火窗的分类、耐火完整性试验设备,并对试验中遇到的一些问题进行探讨,以期为耐火窗的国标制定和企业生产提供有效帮助。

In recent years, exterior wall insulation fire accidents have occurred frequently,which have caused great losses to the country and the people. On May 1,2015,our country implemented the GB 50016---2014 ＂Code for fire protection design of building＂, which made strict requirements for the burning performance of the building insulation materials with different types and different heights, and made strict rules for integrity of the windows on the exterior wall of buildings. This paper mainly discusses the classification of the fire-proof windows, fire-resistant integrity test equipment, and some problems encountered in the experiment,hoping to provide effective help for the national standard formulation and enterprise production of the fire-proof windows.
