卷帘门在防火分区中的分隔设置

防火卷帘门主要用来分隔大空间形成防火分区，起到很有可见性的分隔作用。防火卷帘门的优势在于既可以让防火卷帘在收起后具有较好的装饰效果，又能够在防火分隔中通过醒目且穿透力较强的颜色提示人们火灾事故中中的逃生路径，为有效的逃生争取时间。硬质快速卷帘门根据现场的需要防火卷电控箱上可以设置一步降和二步降。

Fireproof rolling shutter doors are mainly used to separate large spaces and form fire compartments, playing a highly visible role in separating them. The advantage of fireproof rolling shutter doors is that they can provide good decorative effects after being folded up, and can also indicate people's escape routes in fire accidents through eye-catching and strong penetrating colors in fire compartments, buying time for effective escape. Hard fast rolling shutter doors can be equipped with one-step and two-step lowering on the fire resistant roll control box according to on-site needs.

在高层建筑之中，特级防火卷帘的有效防火分隔区域的选取与布置就成为了能否使特级防火卷帘收获其应有的有效防火功能的关键。

In high-rise buildings, the selection and layout of effective fire separation areas for special grade fire resistant rolling shutters have become the key to enabling them to achieve their expected effective fire protection functions.

所以济南防火卷帘门安装维修人员认为需要在不影响正常的生活与有效防火分隔两者之间取得平衡。一般来讲高层建筑内设有上下层相连通的走廊、敞开楼梯、自动扶梯、传送带等开口部位时，应按上下连通层作为一个防火分区，硬质快速卷帘门其允许Z大建筑面积之和不应超过以其建筑等级所设定的防火分区建筑面积。

So the installation and maintenance personnel of Jinan fire resistant rolling shutter doors believe that it is necessary to strike a balance between not affecting normal life and effective fire separation. Generally speaking, when there are corridors, open stairs, escalators, conveyor belts and other openings connecting the upper and lower floors in high-rise buildings, the upper and lower connecting floors should be considered as a fire compartment. The sum of the allowable Z large building area for hard fast rolling shutter doors should not exceed the fire compartment building area set based on their building level.

当上下开口部位设有耐火极限大于3.00h的防火卷帘或水幕等分隔设施时，其面积可不叠加计算。而房间与中庭相通的过厅、通道等，硬质快速卷帘门应设乙级防火门或耐火极限大于3.00h的防火卷帘分隔。

When there are partition facilities such as fire resistant rolling curtains or water curtains with a fire resistance limit greater than 3.00h at the upper and lower openings, their area may not be calculated by superposition. For corridors and passages connecting the room and the atrium, hard fast rolling shutter doors should be equipped with Class B fire doors or fire resistant rolling shutter partitions with a fire resistance limit greater than 3.00 hours.
