Description
Technical Field
The utility model belongs to the technical field of the fire prevention rolling slats door, especially, relate to a vertical lift fire prevention rolling slats door.
Background
The fire-proof rolling curtain is a building fire-proof product developed for further implementing a fire-fighting policy of 'mainly preventing and eliminating fire' and is an indispensable fire-proof facility in modern high-rise buildings. The fire-proof and smoke-proof fire-proof door has the special functions of fire prevention, smoke insulation, fire spread inhibition and personnel evacuation protection, and is widely applied to occasions with dense personnel, such as high-rise buildings, large-scale shopping malls, warehouses, factory buildings, underground garages, restaurants and the like.
The fire-proof rolling curtain and the fire-proof smoke-proof rolling curtain are necessary products for fire prevention and smoke prevention in a large opening or a large area shared space, and cannot be replaced by a common flat-open fire-proof door. The width and height of the size which can be provided by the domestic manufacturer can reach 15m, the smoke detector can be concealed in a suspended ceiling at ordinary times and matched with a temperature-sensing detector and a smoke-sensing detector, and the standard that a smoke-sensing signal comes temporarily and a door is lowered to 1.8 m away from the ground can be achieved, so that a smoke blocking groove is formed in an area, and smoke is prevented from diffusing to other subareas. When the temperature signal comes temporarily, the door body falls to the ground after the disaster is confirmed, the fire source is cut off, and meanwhile, the sound and light alarm is sent out to guide people to evacuate rapidly. If people are still not evacuated in time in the disaster area, the door can be lifted to the height of 1.8 meters from the ground by the buttons on the two sides of the door, and the door is closed in a delayed manner after people escape, so that fire smoke is prevented from escaping outwards.
In general, a large building is provided with a fire protection centralized control system according to the regulations of the national fire protection act. When a fire disaster occurs, a smoke detector (smoke detector for short) arranged on the roof receives a smoke signal and gives an alarm to a central control system at the same time, and the fire-fighting central control system switches on a power supply of a fire-fighting rolling door in the area of the fire disaster after identification so as to enable the fire-fighting rolling door in the area of the fire disaster to descend at a certain speed. When the roller shutter descends to a position about 1.5 meters away from the ground, the descending is stopped, so that the evacuation and evacuation of people are facilitated. And after the fire-proof rolling door stays in the middle for a certain time, the rolling door continues to move downwards until the rolling door is closed. The down speed and the intermediate stay time of the fire door can be adjusted during installation.
In addition, aiming at the problem that the rolling door can not play a role under the condition of no power supply, related units have developed a 'fire-proof rolling door fusing release placement' which can open the speed reduction clutch by temperature fusing under the condition of no power supply or power supply cut-off, so that the fire-proof rolling door can be closed at a constant speed by self weight, and the fire condition is isolated, and the fire-proof rolling door can still play a due role under the condition of no power supply and no person. In some passage openings and staircases with large flow, the standard design is that one side or two sides of a fireproof rolling door are provided with a fixed single-leaf flat-open fireproof door.
The existing fireproof rolling doors in the market are mainly classified into horizontal fireproof rolling doors, vertical lifting rolling doors, side-rolling fireproof rolling doors and the like, the rolling doors are made of special steel structures and composite steel structures, and the operation mode of the rolling doors is generally controlled by an electric motor.
The domestic fireproof rolling shutter door mainly makes innovation breakthrough from the aspect of manufacturing materials, the inorganic cloth-based fireproof rolling shutter door which is researched and developed at present is a bold innovation of new materials in the field of rolling shutter door fire prevention, the rolling shutter door made of the materials has stronger fire prevention and heat insulation effects, the weight of the rolling shutter door is reduced, the running burden of a motor and the fatigue loss of elements are reduced, and meanwhile, the rolling shutter door is more convenient to manufacture and has good adaptability to various door opening sizes. The inorganic fabric-based roller shutter door is mainly made of expanded ceramic fibers subjected to fire resistance testing, and connecting lines on the surface of the roller shutter door are fixed by galvanized plates or stainless steel materials, so that the toughness and the pressure bearing capacity of the roller shutter door are improved, and the roller shutter door is light and attractive. The rolling door support is made of an aluminum alloy support, the whole weight of the rolling door is light, and the bearing strength of the aluminum alloy is completely acceptable, so that the thickness of the rolling door is greatly reduced, the thickness of the fireproof rolling door produced by the latest process is only 2mm at present, and in addition, the aluminum alloy support has a strong abrasion resistance effect, so that the phenomenon that the rolling door is blocked due to long-term non-use or corrosion of a humid environment is prevented.
The control system of the domestic roller shutter door is continuously innovated and upgraded, and the novel automatic control system starts to use a hydraulic telescopic technology to replace the prior method of largely using gears and chains to carry out transmission type operation. In the research and development of the automatic alarm system of the fireproof rolling door, a remote controllable data receiving system is adopted, the regulation is not carried out by depending on a single temperature sensing chip any more, the comprehensive analysis of a fire scene and the evacuation aspect of personnel is carried out by a remote computer, the closing time of the rolling door can be accurately grasped, and the evacuation of the personnel is guaranteed.
In the aspect of research and development of future fireproof rolling doors, the improvement of fireproof effect of the rolling doors can be emphasized, the mechanical reliability is enhanced, and a control system is more humanized and intelligent in transformation and upgrading.
Therefore, there is a need for a vertical lift fire-proof rolling shutter door, which is insensitive to start when avoiding fire, and which can effectively block fire flow and prevent further spread of fire for personnel to have an escape time.
