Knowledge of installation of fire shutter doors

Generally speaking, the setting occasions of fire shutter doors require clear regulations on their design and use, especially the partition door with special requirements for fire prevention and smoke prevention. For example, the partition doors of the equipment room with fixed fire extinguishing device, ventilation and air conditioning machine room attached to high-rise civil buildings should adopt Class A fire doors; The door on the partition wall of the basement room where people often stay or there are many combustibles should adopt Class A fire doors; Due to the restriction of conditions, it is necessary to arrange oil-fired and gas-fired boilers, oil-immersed power transformers filled with oil, high-voltage capacitors and switches filled with oil, etc. in high-rise buildings, and the doors on the partition walls of special rooms should adopt Class A fire doors. There are also sub-doors with special requirements for fire prevention, such as sub-doors of fire control command center, file reference room, valuables warehouse, etc., and Class A or Class B fire doors are usually selected. Fire-proof security doors are often used for the household doors of high-rise residential buildings.


In addition, in order to strengthen the practicability of fire shutter doors, it is necessary to correctly divide fire partitions in applicable occasions and control the doors on the firewalls and fire partitions set up in the construction area of the partitions.
