Fire Knowledge: fire shutter doors Classification and scope of use – fireproof m
Fire shutter doors to play the same role with the firewall level fire separation, which consists of curtain panels, seat, guide, support, reel, box, control box, roll door stopper, lintels, manual speed up switch devices , buttons, switches and protective devices such as 13 parts, usually installed in the inconvenient parts separated by a firewall. Such as: open elevator hall, escalators, department store's large business hall, exhibition hall of the exhibition floor, and building a larger hole can not be used Fire doors Window position. Fire shutter doors in the building, to make fire separated by the vast number of applications.
Fire shutter Category: Divided by material: steel, composite, inorganic and so on.
Form of installation: wall, the wall side (or inside, outside of) two.
By opening direction can be divided into: two volumes on the volume and side.
Fire shutter fire performance rating there is no national standard, GB14102 "steel fire shutter General Technology Conditions "will be divided into ordinary steel fire shutter:
1 level, fire-resistant time 1.50h
F2 grade, fire resistant 2.0h
Composite steel fire shutter is divided into:
F3 level, fire-resistant time 2.50h
F4-class, fire-resistant time 3.00h But the national standard GB14102
steel fire shutter doors on the fire resistance rating, were not asked back the fire resistance test measuring surface temperature, surface temperature rise not to fire back as the time to determine the conditions of fire, appeared on the market in recent years steam fog-type steel fire shutter, evaporative steam fog-type steel fire shutter, etc., by "high regulation" requirement, when used as a fire partition separating the components must be to fire back surface temperature rise as the fire resistance of the judge conditions. To determine the difference between these two different conditions of the fire shutter fire resistance of the classification, classification in the fire curtain before the introduction of national standards, "high regulation" management experts recommended that: will be the national standard "door and shutter resistance test method "GB7633 resistance test, to include the back surface temperature fire conditions in the determination of requirements, fire resistance 3.0h, called super fire shutter, all in the fire resistance test is not to fire back surface temperature l determine the conditions referred to as the ordinary fire shutter doors.
Fire shutter doors where the general settings?
Decisions based on technology, fire shutter, apart from setting the firewall, the partitions between the two fire without a firewall should be set to fire shutter. Generally located in the following positions.
(1) closed staircases, leading to the aisles; closed elevator, room and front room to move through the aisle toward the door.
(2) cable wells, tube wells, flue, vertical tube wells and other garbage Road inspection door.
(3) division of fire protection zone, control area established by the firewall and floor area on the fire wall door. When building a firewall or fire door set to have difficulty, use the fire shutter doors instead of at the same time to protect the water curtain.
(4) norms (such as GB50045-95 "Building Energy Standards") or design special request fire, smoke the wall splitting the door. For example: senior civil attached to the fixed fire extinguishing equipment equipment rooms (cylinder chamber, foam stations, etc.) Ventilation , Air-conditioning room partition doors, etc. Class A fire doors should be used; frequent stay or more fuel on the basement door of the room walls, fire doors should be Grade A; due to constraints, must High-rise building Disposition of fuel, gas boiler, fuel oil-immersed power transformers may be, can be filled with fuel and switch high-voltage capacitors, special room wall on the door, fire doors should be adopted class.
