2, fire shutter is a kind of fire separation facilities, usually used for fire partition, when a fire occurs, it can automatically fall, like a wall, to prevent the fire from spreading.
3. The fire-resistant time of fire curtain is much shorter than that of fire shutter.
Fire shutter is a kind of fire-proof and heat-insulating facility suitable for building entrance. The product adopts the design of built-in reel, which has the characteristics of reasonable and compact structure.
The curtain surface of the fire shutter can be lifted by the transmission device and the control system. It plays the role of fire prevention and isolation, and the product has smooth and beautiful appearance, novel shape and strong rigidity. Fire shutter doors are widely used in fire zones 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. Generally, it is rolled in the rotating shaft box at the top of doors and windows, and it is put down when it catches fire to prevent the fire from spreading from doors and windows. Fire shutter is an essential facility for fire prevention in modern buildings, which has been included 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 horizontal steel fire shutter. Widely used in high-end hotels, restaurants, libraries, theaters, 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, and is especially suitable for drought, water shortage and water avoidance places.
In the early 1980s, steel fire doors, steel fire shutter doors, steel fire shutter doors and steel composite fire shutter doors were gradually popularized and applied in China buildings. It has played a very good role in building fire prevention, and has now formed industrial production in the country. The Code for Fire Protection Design of High-rise Civil Buildings (hereinafter referred to as the "High Code") clearly stipulates the separation area of fire protection zone and smoke prevention zone of buildings. In this paper, the building materials used in the partition and the fire rating and types of the doors used are discussed in detail, which is of great guiding significance to the engineering design of designers and the engineering audit of fire control construction auditors.
