The layout position of fireproof rolling shutter doors

According to the process decision, in addition to being installed on the firewall, fire-resistant rolling shutter doors should also be installed between two fire compartments without a firewall. Generally located in the following areas.
(1) Enclosed evacuation stairs leading to walkways; Enclosed elevator room with doors leading to the front room and the hallway.
(2) Inspection doors for vertical pipeline shafts such as cable shafts, pipeline shafts, smoke exhaust ducts, and garbage lanes.
(3) Divide fire zones, control the building area of the zones, and install firewalls and doors on fire partitions. When it is difficult to install firewalls or fire doors in buildings, fire-resistant rolling shutter doors should be used instead, and water curtains should be used for protection.
The main application places of fireproof rolling shutters
Mainly used in public places with fire protection requirements, such as large supermarkets (supermarkets), shopping malls, large professional material markets, large exhibition halls, factories, warehouses, etc. When a fire alarm occurs, the fireproof rolling shutter door is automatically lowered (lowered) according to the pre-set program under the control of the fire central control system, thereby preventing the spread of flames to other areas and buying valuable time for implementing fire extinguishing.
The production requirements for fireproof rolling shutter doors are high, which requires the entire system to withstand a certain period of high temperature test of around 1100 ° C. The fire resistance time of fireproof rolling shutter doors is the main indicator. GB14102-93 General technical conditions for steel fire-resistant rolling shutter doors specify four fire resistance levels for fire resistance time.
