目前我国现行的防火设计规范中主要的有国家标准《建筑设计防火规范》(GBJ16-87,以下简称《普规》)和《高层民用建筑设计防火规范》(GBJ45-82,以下简称《高规》)这两本规范。无论是《普规》还是《高规》均在其后的附录中,以表格的形式列出了常用建筑材料和构件的燃烧性能和耐火极限数据,供工程技术人员采用。笔者在使 At present, China’s current fire protection design specifications mainly include the national standard “Code for Fire Protection in Architectural Design” (GBJ16-87, hereinafter referred to as “General Regulations”) and “High-rise Civil Building Design Fire Prevention Code” (GBJ45-82, hereinafter referred to as “High Regulations”). )) These two specifications. Both the “General Regulations” and the “High Regulations” are in the subsequent appendices. The combustion performance and fire-resistance limit data of commonly used building materials and components are listed in tabular form for use by engineers and technicians. The author is making
