根据以上材料,回答问题:

对于该办公楼屋顶直升机停机坪有哪些要求?

答案

参考答案:

当建筑某楼层着火导致人员难以向下疏散时,往往需到达上一避难层或屋面等待救援。在超高层建筑的屋面设置屋顶直升机停机坪,可便于直升机从建筑顶部实施救援,是一种可行的救生措施。根据《建筑设计防火规范》(GB 50016--2014)的规定,该塔楼宜设置屋顶直升机停机坪或供直升机救助的设施,并应符合下列规定:

(1)设在屋顶平台上的停机坪,距设备机房、电梯机房、水箱间、共用天线等凸出物的距离,不应小于5m。

(2)出口不应少于两个,每个出口宽度不宜小于0.90m。

(3)在停机坪的适当位置应设置消火栓。

(4)停机坪四周应设置航空障碍灯,并应设置应急照明。
