防火卷帘门一般设置在哪里
Where is the fireproof rolling shutter door generally set
根据工艺流程,两防火分区之间无防火墙时,除设置防火墙外,还应设置防火卷帘门。它通常位于以下部分。
According to the process flow, if there is no firewall between the two fire compartments, in addition to the firewall, the fire rolling shutter door shall also be set. It is usually located in the following sections.
(1) 通往走道的封闭式疏散楼梯;关闭电梯间、通向前室的门和通向走道的门。
(1) Enclosed escape stairs to walkways; Close the elevator lobby, doors to the front room and doors to the walkway.
(2) 划分防火分区,控制防火分区的建筑面积,在防火分区上设置防火墙和门。当建筑物内难以设置防火墙或防火门时,应改为使用防火卷帘门,并采用水幕进行保护。
(2) Divide the fire compartment, control the building area of the fire compartment, and set up firewalls and doors on the fire compartment. When it is difficult to set firewall or fire door in the building, the fire rolling shutter door shall be used instead and protected by water curtain.
(3) 规范(如GB50045-95《高层民用建筑设计防火规范》)或对防火、防烟有特殊要求的隔墙门。例如:在高层民用建筑(气瓶间、泡沫站等)内设置固定式灭火设备间,通风空调间隔墙门应采用a级防火门。地下室房间隔墙上经常有人居住或可燃物较多的门采用高等级防火门;由于条件限制,需要在高层建筑中安装燃油和燃气锅炉、燃油浸入式电力变压器、燃油填充高压电容器和开关。特殊房间隔墙门采用a级防火门。也有专门设计防火要求的户用门,如消防监控指挥、档案资料室、贵重物品仓库等,一般选用A级或B级防火门。
(3) Codes (such as GB50045-95 code for fire protection design of high rise civil buildings) or partition doors with special requirements for fire and smoke prevention. For example, in the high-rise civil building (gas cylinder, foam station, etc.), there is a fixed fire extinguishing equipment room. High grade fire doors shall be used for doors that are often inhabited or have more combustibles on the partition walls of basement rooms; Due to limited conditions, it is necessary to install oil and gas boilers, oil immersed power transformers, oil filled high-voltage capacitors and switches in high-rise buildings. Class a fire door shall be adopted for partition door of special room. There are also household doors specially designed for fire protection requirements, such as fire monitoring and command, archives and reference room, valuables warehouse, etc. generally, class A or class B fire doors are selected.
防火卷帘门的适用范围:
Application scope of fireproof rolling shutter door:
主要用于大型超市(超市)、大型商场、大型材料市场、大型展厅、工厂、仓库等有消防要求的公共场所。当发生火灾报警时,消防卷帘门在中间消防系统的控制下,按预设程序自动放下(放下),防止火焰蔓延到其他区域,争取宝贵的灭火时间。
It is mainly used in large supermarkets (supermarkets), large shopping malls, large material markets, large exhibition halls, factories, warehouses and other public places with fire protection requirements. In case of fire alarm, the fire rolling shutter door will automatically put down (put down) according to the preset procedure under the control of the intermediate fire protection system to prevent the flame from spreading to other areas and strive for valuable fire extinguishing time.
在正常情况下,根据国家消防法的规定,大型建筑物配备中间消防系统。当火灾发生时,安装在屋顶上的烟雾传感器(以下简称烟雾传感器)首先接收烟雾信号并向中间控制系统发出警报。经识别后,中间消防系统接通火区防火卷帘门电源,使火区防火卷帘以一定速度下降。当卷帘下降到离地1.5m左右时,停止下降,以便于人员疏散。防火卷帘门在中间停留一段时间后,继续关闭直至关闭。防火卷帘门的下降速度和中间停留时间可在安装过程中调节。
Under normal circumstances, according to the provisions of the national fire protection law, large buildings are equipped with intermediate fire protection systems. When a fire occurs, the smoke sensor installed on the roof (hereinafter referred to as the smoke sensor) first receives the smoke signal and sends an alarm to the intermediate control system. After identification, the intermediate fire protection system connects the power supply of the fire rolling shutter door in the fire area, so that the fire rolling shutter in the fire area decreases at a certain speed. When the roller shutter drops to about 1.5m above the ground, stop the descent to facilitate personnel evacuation. After the fireproof rolling shutter door stays in the middle for a period of time, continue to close until it is closed. The falling speed and the median residence time of the fire shutter doors can be adjusted during installation.
在某些情况下,建筑物未配备中间消防系统,消防卷帘门仅借助消防卷帘门的消防电气箱实现消防卷帘门的消防规定操作程序。在这种情况下,当发生火灾报警时,烟雾传感器接收到的火灾报警信号直接传输到防火卷帘门的消防电气箱。
In some cases, the building is not equipped with an intermediate fire-fighting system, and the fire rolling shutter door only realizes the fire-fighting specified operating procedures of the fire rolling shutter door with the help of the fire-fighting electrical box of the fire rolling shutter door. In this case, when a fire alarm occurs, the fire alarm signal received by the smoke sensor is directly transmitted to the fire electrical box of the fire rolling shutter door.
停电时,防火卷帘门只能拉铁链才能放下。防火卷帘门采用手动,只能向一个方向下降,不能提升。
In case of power failure, the fireproof rolling shutter door can only be put down by pulling an iron chain. The fireproof rolling shutter door is manually operated, which can only be lowered in one direction and cannot be lifted.
的制造要求较高,即要求整个系统能经受1100°左右的高温试验一段时间。防火卷帘门的耐火时间是防火卷帘门的主要指标。Gb14102-93《钢制防火卷帘门通用技术条件》规定了耐火时间的四个防火等级。
The manufacturing requirements are high, that is, the whole system is required to withstand a high temperature test of about 1100 ° for a period of time. The fire resistance time of fireproof rolling shutter door is the main index of fireproof rolling shutter door. Gb14102-93 general technical conditions for steel fireproof rolling shutter doors specifies four fire rating of fire resistance time.
