Where are the fireproof rolling shutter doors generally installed

Henan fire rolling shutter door is determined according to the process. In addition to being set in the firewall, fire rolling shutter door shall also be set if there is no firewall between two fire compartments. It is generally located at the following parts. (1) Close the evacuation staircase to the walkway; Enclose the elevator hall, the door leading to the front room and the front room leading to the walkway. (2) Divide the fire compartment and control the fire wall and the door on the fire partition in the building area of the compartment. When it is difficult to set firewall or fire door in the building, fire rolling shutter door shall be used instead, and water curtain shall be used for protection. (3) Code (such as GB50045-95 Code for Fire Protection Design of High rise Civil Buildings) or partition door with special requirements for fire and smoke prevention. For example, the partition doors of equipment rooms (cylinder rooms, foam stations, etc.) attached with fixed fire extinguishing devices in high-rise civil buildings, ventilation, air conditioning rooms, etc. should be Class A fireproof doors; The door on the partition wall of the basement room where people often stay or there are many combustibles shall be Class A fireproof door; Due to limited conditions, it is necessary to arrange oil fired and gas-fired boilers, oil immersed power transformers, high voltage capacitors and switches filled with oil, etc. in high-rise buildings. The doors on the partition walls of special rooms should be Class A fireproof doors. There are also household doors with special requirements that must be fireproof, such as fire control command center, archives room, valuables warehouse, etc., which usually use Class A or Class B fireproof doors.

Restricted area of super fireproof rolling shutter

In the use of super fireproof roller shutter, because it is mainly used in the rapid formation of fire separation area, and is mostly set up in applications with large space, as a visible fire separation device, generally in the production of fireproof roller shutter, the fireproof roller shutter will be painted with a more striking color, It can not only make the fireproof rolling shutter have a better decorative effect after being folded, but also can remind people of the escape route in fire accidents through eye-catching and penetrating colors in the fire compartment, so as to buy time for effective escape.

In addition to the fire separation device used in fire accidents, the fire rolling shutter door in the setting of super grade fire rolling shutter shall be closed at ordinary times to ensure that the normal life of people is not affected as much as possible. Therefore, in high-rise buildings, the selection and layout of the effective fire separation area of the super grade fire shutter has become the key to whether the super grade fire shutter can harvest its effective fire prevention function. Therefore, it is necessary to strike a balance between not affecting normal life and effective fire separation. Generally speaking, when there are corridors connecting the upper and lower floors, open stairs, escalators, conveyor belts and other openings in high-rise buildings, the upper and lower connecting floors should be regarded as a fire compartment, and the sum of the allowable large building area should not exceed the building area of the fire compartment set by its building grade. When the upper and lower openings are equipped with partition facilities such as fire rolling curtains or water curtains with a fire resistance limit of more than 3.00h, the area can be calculated without superposition. The hall and passageway connecting the room and the atrium shall be separated by Class B fireproof doors or fireproof rolling shutters with a fire resistance limit of more than 3.00h.

It can be seen that the super fireproof roller shutter can play a good role in fire separation, but it is not that more can be set at will, but it needs to be designed and installed according to scientific calculation and building use area.
