Area Calculation

Fire shutter doors area calculation should be performed according to the national building engineering fields standard is calculated as: (fire shutter door opening height + 600mm) * (shutter door opening width + 200mm) Notes: (hole height under the beam to the hair surface, rails need embedded ) pack boxes and lintel area is calculated as: (hole width) * (bottom surface elevation +) to expand the computing area.

The arrangement position

Based on the decision process, in addition to setting fire shutter doors outside the firewall between the two fireproof partitions without a firewall should also be set up fire shutter is generally located in the following parts (1) closed staircases, leading to the walkway;.. Closed elevator , through the forward compartment and the walkway leading to the door of the front room. (2) Cable wells, tube wells, flue, garbage Road tube wells and other vertical inspection door. (3) into the fire district, controlling the construction area of ​​the partition Let firewalls and fire doors on the wall. When building a firewall or fire doors have difficulty, use fire shutter doors replaced, while the water curtain to be protected. The main application areas are mainly used for fire shutter supermarkets (hypermarkets) , shopping malls, large specialty materials market, a large exhibition hall, factories, warehouses and other public places have fire protection requirements. When the fire broke out, fire shutter doors fire under control of the central control system, according to pre-set the program to automatically drop (downlink ), so as to prevent the flames from spreading to other areas of action for the implementation of fire protection for valuable time high production requirements of fire shutter doors, which requires the entire system can withstand about 1100 ° high temperature test, fire shutter doors of fire resistance for some time It is the main indicator .GB14102-93 steel fire shutter door general technical conditions of fire shutter doors refractory time specifies the four fire rating.
