摘　　要：研究钢网架防火保护方法,列举常用建筑钢结构构件防火保护方法,比较不同防火保护方法保护钢网架结构的优缺点,认为屏蔽法适用于钢网架结构的防火保护。结合某场馆钢网架结构采用屏蔽法进行防火保护的工程实例,进行保温隔热材料厚度计算,介绍防火保护吊顶设计,验算钢网架承载力,说明采用屏蔽法对钢网架结构进行防火保护的设计方法,为类似结构的防火保护提供参考依据。In order to research the fire protection method of steel space truss structures, the fire protection methods of steel structures were listed. For steel space truss structures, the advantages and disadvantages of fire protection methods were introduced. The screen method was suitable for fire protection of steel space truss structures. One project of fire protection of steel space truss structure was shown as an example. The thickness of insulation materials was calculated and the design of fire proof ceiling was introduced, the gravity load of steel space truss structure was calculated. The process of screen method was provided for fire protection of steel space truss structures. According to this project, the technology of fire protection of steel space truss structures was enriched. This example could help to deal with fire protection of steel space truss structures.
