摘　　要：目前,工程中耐火风管只关注耐火极限,缺少抗震、隔热、燃烧性能方面的要求,造成耐火风管的部分性能不符合规范要求。针对此问题,结合规范要求,对耐火极限、抗震性能、隔热性能、燃烧性能对耐火风管的特性进行研究,给出了相应的指标要求。At present,the refacrory duct in the project only pays attention to the fire-resistant limit,and lacks the requirements of seismic performance,heat insulation and combustion performance,resulting in some performance of the refacrory duct not meeting the requirements of the code.In view of this problem,combined with the requirements of the code,the characteristics of the refacroryduct are studied from the fire-resistant limit,seismic performance,heat insulation performance and combustion performance,and the corresponding index requirements are given to provide reference for engineering design and final acceptance of the project.

关 键 词：耐火风管 耐火极限 隔热层 导热系数 燃烧性能
