答案

参考答案:

检查内容:

(1)广场的开敞区域

不同防火分区通向下沉式广场等室外开敞空间的开口最近边缘之间的水平距离不得小于13m。

室外开敞空间除用于人员疏散外不得用于其他商业或供人员通行外的其他用途,其中用于疏散的净面积不得小于169m2。

(2)广场直通地面的疏散楼梯

为保证人员逃生需要,直通地面的疏散楼梯不得少于1部。当连接下沉广场的防火分区需利用下沉广场进行疏散时,该区域通向地面的疏散楼梯要均匀布置,使人员的疏散距离尽量短。疏散楼梯的总净宽度不得小于任一防火分区通向室外开敞空间的设计疏散总净宽度。

(3)广场防风雨棚的设置

防风雨棚不得完全封闭,四周开口部位要均匀布置,开口的面积不得小于室外开敞空间地面面积的25%,开口高度不得小于1.0m;口设置百叶时,百叶的有效排烟面积可按百叶通风口面积的60%设置。
