Navigation < It plays the role of fire prevention and fire isolation, and the product has the characteristics of smooth and beautiful appearance, novel shape and strong rigidity. Fire shutter doors are widely used in fire partition areas of industrial and civil buildings, which can effectively prevent the fire from spreading and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. It is a movable fireproof partition, which is generally made of metal plates such as steel plates, and consists of buckles or hinges. It is usually rolled up in the rotating shaft box at the top of doors and windows, and it is put down and unfolded when it catches fire to prevent the fire from spreading from the doors and windows. Fire shutter is a necessary facility for modern building fire prevention, which has been listed in the national code for fire protection design of buildings and other buildings. The main types are vertical steel fire shutter, lateral steel fire shutter and recumbent steel fire shutter. Widely used in advanced hotels, restaurants, libraries, theaters, large shopping malls, stations, underground projects and factories, warehouses, garages and other buildings. Fire shutter is divided into ordinary type and compound type according to the type of shutter. The common type has many functions such as fire prevention, smoke prevention, wind prevention, rain prevention and theft prevention. The compound type has the same function as the ordinary type, but it does not need water curtain protection, which is especially suitable for dry and water-deficient places.
in the early 198s, the Code for Fire Protection of Steel Fire Doors and Steel Fire Shutters (hereinafter referred to as "High Code") clearly defined the separation area of fire protection zones and smoke prevention zones in buildings. This paper discusses in detail the building materials used in the partition and the fire protection grade and type of doors, which is of great guiding significance to the engineering design of designers and the engineering audit of fire control construction auditors.
in p>193, the steel fire shutter appeared, in 1993, the inorganic cloth fire shutter appeared, and in 2, the inorganic super fire shutter appeared (Intel Morgan had an invention patent).
