防火卷帘门应该设置在哪?
2018-7-11 10:53:55

依据工艺决定的,防火卷帘门除设置在防火墙外,在两个防火分区之间没有防火墙的也应设置防火卷帘。一般设在以下部位。
According to the technology, the fire shutter doors should be installed outside the firewall, and there should be no fire shutters between the two fire zones. It is generally located in the following parts.
(1)封闭疏散楼梯,通向走道;封闭电梯间,通向前室及前室通向走道的门。
(1) close the evacuation staircase to the walkway; close the elevator compartment, leading to the front room and the front room leading to the aisle door.
(2)电缆井、管道井、排烟道、垃圾道等竖向管道井的检查门。
(2) inspection doors for vertical wells, such as cable wells, pipe wells, smoke exhaust roads, garbage roads, etc.
(3)划分防火分区,控制分区建筑面积所设防火墙和防火隔墙上的门。当建筑物设置防火墙或防火门有困难时,要用防火卷帘门代替,同时须用水幕保护。

(3) divide fire prevention zones, control the firewalls and the doors on firewalls. When building a firewall or fire door is difficult, replace it with a fire shutter door and use water curtain to protect it.

(4)规范(如GB50045-95《高层民用建筑设计防火规范》)或设计特别要求防火、防烟的隔墙分户门。例如:附设在高层民用建筑内的固定灭火装置的设备室(钢瓶室、泡沫站等),通风、空气调节机房等的隔墙门应采用甲级防火门;经常有人停留或可燃物较多的地下室房间隔墙上的门,应采用甲级防火门;因受条件限制,必须在高层建筑内布置燃油、燃气的锅炉,可燃油油浸电力变压器,充有可燃油的高压电容器和开关等,专用房间隔墙上的门,都应采用甲级防火门。还有设计有特殊要求的须防火的分户门,如消防监控指挥中心、档案资料室、贵重物品仓库等的分户门,通常选用甲级或乙级防火门。高层高级住宅楼的分户门,常采用防火防盗门。
(4) specifications (such as GB50045 95 "code for fire protection design of high-rise civil buildings") or specially designed fire prevention and smoke prevention partition door. For example, the equipment room attached to the fixed fire extinguishing device in the high-rise civil building (the cylinder room, the foam station, etc.), the partition door of the ventilation and air conditioning room should be a class a fireproof door, and the door on the wall on the wall of the basement room which often stays or more combustible should be used in a class a fireproof door; due to the conditions, it is necessary. Fuel and gas fired boilers should be arranged in the high-rise buildings, oil immersed power transformers, high pressure capacitors and switches which can be filled with fuel, and a class a fire protection gate should be used in the door on the partition wall of the special room. There are also special requirements for fire protection door, such as fire control and command center, file room, valuables warehouse and other door, usually select a Class A or the second class fire door. Fire door is often used in high-rise residential buildings.
主要用于大型超市(大卖场)、大型商场、大型专业材料市场、大型展馆、厂房、仓库等有消防要求的公共场所。当火警发生时,防火卷帘门在消防中央控制系统的控制下,按预先设定的程序自动放下(下行),从而达到阻止火焰向其他范围蔓延的作用,为实施消防灭火争取宝贵的时间。
It is mainly used for large supermarkets, shopping malls, large professional materials markets, large exhibition halls, factories, warehouses and other public places with fire requirements. When the fire alarm occurs, the fire curtain door is controlled by the central control system of the fire control system and is automatically lowered (down) according to the pre set program, thus preventing the flame from spreading to the other range, so as to strive for the precious time for the fire fighting and fire fighting.
在通常情况下,大型建筑根据国家消防法的规定配置了消防中央控制系统。当火灾发生时,安装在房顶的烟感传感器(简称烟感)首先接到烟雾信号,同时向中央控制系统报警,消防中央控制系统通过识别后接通火警所在区域的防火卷帘门电源,使火灾区域的防火卷帘按一定的速度下行。当卷帘下行到离地面约1.5米位置时,停止下行,以利于人员的疏散和撤离。防火卷帘门在中间停留一定时间后,再继续下行,直至关闭。防火卷帘门的下行速度和中间停留时间可在安装时进行调整。
Under normal circumstances, the central control system is installed in large buildings according to the provisions of the National Fire Law. When the fire occurs, the smoke sensor installed on the roof (smoke sense) first receives smoke signals, at the same time, alarm the central control system. The fire control central control system passes the fire curtain door power supply in the area of the fire alarm, so that the fire rolling curtain in the fire area is down at a certain speed. When the shutter is lowered to about 1.5 meters away from the ground, it will stop and descend to facilitate evacuation and evacuation. The fire shutter door stays in the middle for a certain time, then continues downward until it closes. The downstream speed and the n residence time of the fire shutter doors can be adjusted during installation.
在某些场合,建筑内不配备消防中央控制系统,防火卷帘门仅借助于防火卷帘门的消防控制电器箱实现防火卷帘门的防火规定运行程序。在这种情况下,当火警发生时,烟雾传感器接收的火警信号直接传至防火卷帘门的消防控制电器箱。
In some cases, the central control system is not equipped in the building, and the fire curtain door is only used in the fire control electric box of the fire curtain door to implement the fire regulation procedure of the fire curtain door. In this case, when the fire occurs, the smoke signal received by the smoke sensor is directly transmitted to the fire control electrical box of the fire shutter door.
在停电的情况下,只能通过拉动铁链将防火卷帘门放下。防火卷帘门配备的手动,只能单向放下,不能提升。
In the case of power failure, the fire shutter door can only be lowered by pulling the chain. Fire shutter door equipped with manual, can only be put down one way, can not be promoted.
防火卷帘门的制作要求较高,即要求整个系统能经受一定时间的1100°左右高温考验,防火卷帘门的耐火时间是防火卷帘门的主要指标。GB14102-93钢质防火卷帘门通用技术条件中对耐火时间规定了四个防火等级。
The production requirements of the fire curtain door are high, that is, the system requires the whole system to withstand a certain time of 1100 degrees of high temperature test. The fire resistance time of the fire curtain door is the main indicator of the fire curtain door. In the general technical conditions of GB14102-93 steel fire shutter doors, there are four fire protection grades for fire protection time.
