防火卷帘门是一种适用于建筑物较大洞口处的防火、隔热设施，以下是关于防火卷帘门的详细介绍：

Fireproof rolling shutter door is a fireproof and thermal insulation facility suitable for large openings in buildings. The following is a detailed introduction about fireproof rolling shutter door:

主要特点

main features 

结构合理：防火卷帘门采用了卷轴内藏的特点，使得整体结构合理紧凑。

Reasonable structure: The fireproof rolling shutter door adopts the feature of concealed scroll, making the overall structure reasonable and compact.

外观美观：产品外形平整美观，造型新颖，具有刚性强。

Beautiful appearance: The product has a flat and beautiful appearance, a novel shape, and strong rigidity.

防火性能：能在火灾发生时迅速反应并封锁门窗洞口，有效隔离并阻止火势的进一步蔓延，起到防火、隔火、隔烟的重要作用。

Fireproof performance: It can quickly respond and block door and window openings in the event of a fire, effectively isolate and prevent the further spread of the fire, and play an important role in fire prevention, fire isolation, and smoke isolation.

防火卷帘门广泛应用于工业与民用建筑的防火隔断区，具体包括：

Fireproof rolling shutter doors are widely used in fire-resistant partition areas of industrial and civil buildings, including:

中庭防火分隔：当中庭与周围连通空间需要防火分隔时，可以采用防火卷帘。其耐火极限不应低于3.00小时，并符合规范规定。

Fire separation in the atrium: When fire separation is required between the atrium and surrounding connected spaces, fire-resistant rolling shutters can be used. Its fire resistance limit should not be less than 3.00 hours and comply with the specifications.

民用建筑防火分区：在民用建筑中，防火分区之间应采用防火墙分隔。如果确有困难，可以采用防火卷帘等防火分隔设施。

Fire compartments in civil buildings: In civil buildings, fire compartments should be separated by firewalls. If there are indeed difficulties, fire separation facilities such as fireproof rolling shutters can be used.

厂房防火分区：厂房防火分区之间应采用防火墙分隔。除甲类厂房外的一、二级耐火等级厂房，当其防火分区的建筑面积大于规范规定，且设置防火墙确有困难时，可采用防火卷帘或防火分隔水幕。

Factory fire compartments: Fire walls should be used to separate the fire compartments of the factory. When the building area of the fire compartment of a first or second level fire-resistant factory building, except for Class A factory buildings, exceeds the standard requirements and it is difficult to install firewalls, fire-resistant rolling shutters or fire-resistant partition water curtains can be used.

仓库防火分区：仓库内的防火分区之间采用防火墙分隔。甲、乙类仓库内防火分区之间的防火墙不应开设门、窗、洞口。对于丙、丁、戊类仓库，在实际使用中确因物流等使用需要开口的部位，需采用与防火墙等效的措施进行分隔，如防火门、防火卷帘。开口部位的宽度一般控制在不大于6.0米，高度尽量控制在4.0米以下。

Warehouse fire compartments: Fire compartments within the warehouse are separated by firewalls. The firewalls between fire compartments in Class A and Class B warehouses should not have doors, windows, or openings. For Class C, D, and E warehouses, in actual use, if there are openings required for logistics and other purposes, measures equivalent to firewalls should be taken to separate them, such as fire doors and fire shutters. The width of the opening is generally controlled to be no more than 6.0 meters, and the height should be controlled as low as 4.0 meters.

特殊部位防火分隔：建筑内的部分特殊部位应采用耐火极限不低于2.00小时的防火隔墙与其他部位分隔，墙上的门、窗应采用乙级防火门、窗。这些特殊部位包括甲、乙类生产部位和建筑内使用丙类液体的部位，厂房内有明火和高温的部位，甲、乙、丙类厂房（仓库）内布置有不同火灾危险性类别的房间，民用建筑内的附属库房、剧场后台的辅助用房，除居住建筑中套内的厨房外，宿舍、公寓建筑中的公共厨房和其他建筑内的厨房，以及附设在住宅建筑内的机动车库。

Fire separation in special areas: Some special areas within the building should be separated from other areas by fire-resistant partitions with a fire resistance limit of not less than 2.00 hours. Doors and windows on the walls should use Class B fire-resistant doors and windows. These special areas include Class A and B production areas, areas where Class C liquids are used in buildings, areas with open flames and high temperatures in factories, rooms with different fire hazard categories arranged in Class A, B, and C factories (warehouses), auxiliary warehouses in civil buildings, theater backstage auxiliary rooms, public kitchens in dormitories and apartment buildings, kitchens in other buildings, and motor vehicle garages attached to residential buildings, in addition to kitchens in residential buildings.

此外，防火卷帘通常被安装在电梯厅、自动扶梯周围的中庭与楼层走道、过厅相通的开口处，以及生产车间中大面积的工艺洞口等位置。在设置防火墙存在困难的区域，也可以考虑安装防火卷帘，以确保建筑物的消防安全。

In addition, fire-resistant rolling shutters are usually installed in elevator lobbies, atrium and floor walkways around escalators, openings that connect to hallways, and large process openings in production workshops. In areas where setting up firewalls is difficult, installing fire-resistant rolling shutters can also be considered to ensure the fire safety of buildings.
