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.

根據(jù)現(xiàn)場需要在防火卷簾門電控箱上設置

在高層建筑中，超級防火帷幕的有效防火分隔區(qū)域的選擇和布局成為超級防火帷幕能否收獲其有效防火功能的關(guān)鍵。

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.

避免影響生活上下兩層連為防火區(qū)

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

需要在不影響正常生活和有效的防火隔離之間取得平衡。一般來說，高層建筑均設有上下連通走廊、開敞樓梯、自動扶梯、傳送帶等開口部分，應將上下兩層連接為防火區(qū)，其硬快速卷簾門允許的較大建筑面積不應超過其建筑等級所規(guī)定的防火區(qū)建筑面積。

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.

當上下開孔設有耐火極限大于3.00h的防火簾或水幕等隔離設施時，面積不得疊加計算。房間與中庭相通的大廳、通道，卷簾門應隔有B類防火門或耐火極限大于3.00h的防火卷簾門。

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.

由此可見，防火卷簾門廠家建議防火卷簾的空間設置需要一定的知識，不能隨便進行設計和安裝。火區(qū)設置的質(zhì)量直接影響到人們的生命財產(chǎn)。

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.
