《建筑设计防火规范》(TJ16-74)规定,有爆炸危险的甲、乙类生产厂房,其外围结构应设泄压面积,泄压设施宜采用轻质屋盖或易于泄压的门、窗、墙,泄压面积与厂房体积之比一般采用0.05～0.1(对其爆炸介质的爆炸下限较低或爆炸压力较强以及体积较小的厂房,还应尽量加大);其内部布置宜采用不致产生火花的地面,不应设置办公室、休息室。这些虽仅为部分要求,却已给建筑设计带来许多困难。危险等级的分类又较笼统,同属一个类中的各不同情况可能相差很悬殊。这就往往促成不进一步区别、不作深入分析地一律对待,在难以完全满足高要求的情况下尽量加大门窗面积、采用 The “Building Design Fire Protection Code” (TJ16-74) stipulates that there are Class A and Class B production plants with explosion hazards, and the surrounding structure should be provided with pressure relief area. Pressure relief facilities should use lightweight roof or doors and windows that are easy to release pressure. The ratio of the pressure relief area to the volume of the factory building is generally 0.05 to 0.1 (the plant whose explosion medium has a lower lower explosion limit or a stronger explosion pressure and smaller volume should be enlarged as much as possible); its internal layout should be adopted Grounds that do not generate sparks should not have offices or lounges. Although these are only part of the requirements, they have brought many difficulties to the architectural design. The classification of danger levels is more general, and the different situations in the same class may be very different. This often leads to no further differentiation and no in-depth analysis. If it is difficult to fully meet the high requirements, the area of ​​windows and doors should be increased as much as possible.
