防火卷簾門經常在一些高層建筑中使用，能夠在遇到險情時起到良好的防火的作用，能夠及時阻攔火災的蔓延，優勢明顯。它的使用具有一定的消防作用，在使用時也有一些要點也需要格外注意，接下來就為大家具體介紹一下防火卷簾門在使用過程中的要點。

Fire shutter door is often used in some high-rise buildings, which can play a good role in fire prevention in case of danger, and can stop the spread of fire in time. It has a certain role in the use of fire protection, there are also some points need to pay special attention to when using, next for you to specifically introduce the key points of the fire shutter door in the use process.

(1)門扇對疏散寬度的影響

(1) Influence of door leaf on evacuation width

防火卷簾門一般位于疏散路線上(如樓梯間、前室、走道等)。建筑平面細部設計稍有不慎，可能導致門扇遮擋疏散路線，開啟后有效寬度減小，違反疏散基本要求。這種現象在疏散路線和高層居住建筑的轉折處尤為突出，應引起重視和避免。

The fire shutter door is generally located on the evacuation route (such as staircase, antechamber, aisle, etc.). A slight carelessness in the detailed design of the building plane may cause the door leaf to block the evacuation route, reduce the effective width after opening, and violate the basic requirements of evacuation. This phenomenon is particularly prominent at the turning point of evacuation routes and high-rise residential buildings, which should be paid attention to and avoided.
                              

(2)通向相鄰分區的疏散口

(2) Evacuation exits leading to adjacent zones

在一定條件下，當有防火卷簾門通向相鄰防火分區時，高層建筑的每個分區只允許有一個出口。需要注意的是，由于防火卷簾門只能向一個方向開啟，如果相鄰兩個分區只有一個出口，則應在防火墻上設置兩個防火卷簾門，分別向兩側開啟，以滿足兩個分區之間相互疏散的需要。

Under certain conditions, when there is a fire shutter door leading to the adjacent fire compartment, each compartment of a high-rise building is only allowed to have one exit. It should be noted that since the fire shutter door can only be opened in one direction, if there is only one emergency exit in two adjacent zones, two fire shutter doors should be set on the firewall to open to both sides to meet the needs of mutual evacuation between the two zones.

(3)啟閉模式的選擇

(3) Selection of opening and closing mode

比較常用的是常閉式防火卷簾門，其門扇始終處于關閉狀態，人經過時手動開啟，通過門扇后自動關閉;如果安裝了推栓硬件，會更有利于加快疏散速度。但位于公共通道的常閉式防火卷簾門存在影響通風采光、遮擋視線、不方便通行等缺點。例如，由于管理不善，閉門器和啟閉的硬件經常被破壞和失效，造成隱患。近年來，常開防火卷簾門恰好了上述問題。平時其門扇由門固定器固定在開啟位置，遇火自動釋放，恢復正常關閉防火卷簾門的功能。

Normally closed fire shutter door is commonly used. Its door leaf is always closed, which can be opened manually when people pass by and closed automatically after passing through the door leaf. If the bolt pushing hardware is installed, it will be more conducive to accelerating the evacuation speed. But the normally closed fire shutter door in the public passage has some disadvantages, such as affecting the ventilation and lighting, blocking the line of sight, inconvenient traffic and so on. For example, due to poor management, the hardware of the door closer and the door opener is often damaged and failed, resulting in security risks. In recent years, often open fire shutter door just solved the above problems. At ordinary times, the door leaf is fixed in the open position by the door holder, which will automatically release in case of fire and restore the function of normally closing the fireproof rolling shutter door.
