摘要
在商业建筑设计中,大型商场疏散楼梯宽度以及借用通向相邻防火分区的防火门作为辅助疏散出口的问题比较突出.应根据大型商场的经营性质确定其人员换算系数,选取“纯营业厅和为顾客服务用房面积”作为基础面积计算疏散楼梯宽度;地上建筑可适当借用通向相邻防火分区的防火门作为其辅助疏散出口,以减少楼梯数量.
In the design of commercial buildings,the widths of fire-escape stairs and the fire-resisting doors to adjoining fire departments served as auxiliary exits in large emporia become quite conspicuous problems.We need to define the conversion coefficients of customers and employees according to the operating characters of large department stores,and calculate the widths of escape stairs by applying 'pure shopping halls and room areas for customer service' as the cardinal areas.Ground buildings may also appropriately use the fire-resisting doors to adjoining fire departments as the auxiliary exits,so as to reduce the number of stairs.
