In commercial buildings and large shopping malls, fire-resistant rolling shutter doors are indispensable fire protection facilities, mainly used to isolate larger spaces into fire zones, effectively separating areas on each floor. Fire resistant rolling shutter doors not only can be used as ordinary doors, but also have special functions such as fire prevention, smoke isolation, preventing fire spread, and protecting personnel evacuation. The manufacturer of the rolling shutter door will organize the requirements for the separation and control of the fireproof rolling shutter door for you. Let's talk about it slowly as follows.

在高层建筑中，超级防火帷幕的有效防火分隔区域的选择和布局成为超级防火帷幕能否收获其有效防火功能的关键。

In high-rise buildings, the selection and layout of the effective fire separation area of the super fire curtain becomes the key to whether the super fire curtain can achieve its effective fire prevention function.

避免影响生活上下两层连为防火区

Avoid affecting daily life by connecting the upper and lower floors as a fire zone

需要在不影响正常生活和有效的防火隔离之间取得平衡。一般来说，高层建筑均设有上下连通走廊、开敞楼梯、自动扶梯、传送带等开口部分，应将上下两层连接为防火区，其硬快速卷帘门允许的较大建筑面积不应超过其建筑等级所规定的防火区建筑面积。

A balance needs to be struck between not affecting normal life and effective fire isolation. Generally speaking, high-rise buildings are equipped with openings such as up and down connecting corridors, open stairs, escalators, conveyor belts, etc. The upper and lower floors should be connected to form a fire zone, and the large building area allowed by hard and fast rolling shutter doors should not exceed the fire zone building area specified by their building grade.

当上下开孔设有耐火极限大于3.00h的防火帘或水幕等隔离设施时，面积不得叠加计算。房间与中庭相通的大厅、通道，卷帘门应隔有B类防火门或耐火极限大于3.00h的防火卷帘门。

When the upper and lower openings are equipped with isolation facilities such as fire curtains or water curtains with a fire resistance limit greater than 3.00 hours, the area shall not be calculated by superposition. The lobby, passage, and rolling shutter doors connecting the room and atrium should be separated by Class B fire doors or fire resistant rolling shutter doors with a fire resistance limit greater than 3.00 hours.

由此可见，防火卷帘门厂家建议防火卷帘的空间设置需要一定的知识，不能随便进行设计和安装。火区设置的质量直接影响到人们的生命财产。

From this, it can be seen that the manufacturer of fire resistant rolling shutter doors suggests that the space setting of fire resistant rolling shutter doors requires certain knowledge and cannot be designed and installed casually. The quality of setting up a fire zone directly affects the safety of people's lives and property.
