Steel fire shutter: It refers to the use of steel material of the curtain plate, rails, base plates, lintels, box, etc., and with a volume control box door and composed shutter can meet the requirements of fire integrity.
Inorganic fiber composite fire shutter: It refers to inorganic fiber material of curtain surface material made with steel cleats, rails, base plates, lintels, box, etc., and with a volume control box door and composed shutter can meet the requirements of fire integrity.
Super fire shutter: It refers to the use of steel material or an inorganic fiber material of curtain surface material used to make steel rails, seat board, plywood, lintel, box, etc., and with a volume control box door and composed can meet fire integrity, every heat and smoke of the area calculation fire shutter door area calculation should be performed according to national construction engineering fields standard is calculated as: (fire shutter door opening height + 600mm) * (shutter door opening width + 200mm) Notes: (hole height under the beam to wool ground, rails need embedded) pack boxes and lintel area is calculated as: (hole width) * (bottom surface + facade) Expand calculate the 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.
