High-rise residential building emergency lighting design problem analysis

Among fell-runners changchun college of engineering energy power engineering institute abstract: in recent years, building electrical field many specifications are updated, many emergency lighting design scheme of the high-rise residential building is not completely suitable for the new specifications, according to the latest specification, emergency lighting design of the high-rise duplex residential building is put forward some problems that should be paid attention to for reference. Key words: emergency lighting; High-rise residential buildings; Control; The code for fire protection with the development of the society, more and more high-rise buildings, high-rise residential building with a large area, complicated structure, crowded, a large quantity of electricity courage with fire characteristics, in the event of fire, personnel and fire fighting and rescue work is very difficult to escape. High-rise residential building with construction layer, vertical travel distance is long, a longer time needed for evacuation to a safe place. For the majority of high-rise residential buildings ( In addition to the above 100 meters tall building) , there is no corresponding reliable refuge floor, and is essentially a unit is only an evacuation stairs, in the event of fire, it is very difficult to evacuate. Emergency lighting in the role of the fire and other special circumstances occur is no doubt. One, the understanding of high-rise residential buildings divided according to 'code for fire protection design of buildings' ( GB50016- 2014). 5. 1. 1 civil structures according to the height of the building and layer can be divided into single and multi-layer civil buildings and high-rise civil buildings. According to the height of the building, the use function of tall buildings and the construction area of floor can be divided into category and the second class. The classification of the civil construction shall comply with the provisions of the table 1. For residential buildings, 'code for fire protection design of buildings with building height 27 meters as a standard to distinguish the multi-storey and high-rise residential buildings; For high-rise residential buildings, with 54 m divided into category and category. Instead of the original state standard 'code for fire protection design of buildings' GB50016 - In 2006 and 'code for fire protection design of tall buildings' GB50045 - In 1995 according to the classification standard of 9 layer and layer of 18. Personal understanding, with the development of the society, the present model and style of the high-rise duplex residential building is more and more diversified, there are many floors high, Some layer up to 5. 9 meters) And the general residential building height is about 2. 8 meters to 3. 2 meters, so that if reoccupy layers to differentiate the high-rise residential building, will appear the same are 10 high-rise residential building, the building height may vary a lot, if reoccupy layer to differentiate, may cause some residential buildings should belong to the category top, the results according to the original standard do not need to be in accordance with the second kind of high-level design, relevant emergency lighting design also can appear problem. Visible existing building height is used to define the new specification standards of multi-storey and high-rise residential buildings is very personalized. Second, high-rise residential building emergency lighting set up relevant basis 'residential building electrical design code' ( JGJ242 - 2011). 9. 3. Article 1, 9. 3. Article 2, 9. 3. Article 3 set emergency lighting for residential building should be set separately. , high-rise residential, emergency lighting of the three types of common common has the following kinds of emergency lighting mode, as shown in figure 1, lamp 1, 2, 3 lamp, lamp light 4, 5 and 6 respectively represent the different types of emergency lighting lamp lamps and lanterns. : 1 lamp represents a mandatory evacuation instructions to the light type accident time tunnel lighting, commonly used in the stairwell of the high-rise duplex residential building, this kind of light is not lit, at ordinary times time to enforce light in such as fire accident. Lamp 2 representative at ordinary times and do the evacuation passageway of general lighting lighting, commonly used in the stairwell of the high-rise duplex residential building, and can be normally open or closed at ordinary times, when the accident happened, if the lamps and lanterns is in turn on the light a state continues to work to light, how can the lamps and lanterns in the lights-out position through fire signal to light up. Lamp type 3 representative Chang Ming emergency lighting lamps and lanterns, commonly used in high-rise residential building of dark staircase, elevator evacuation instructions of lighting and its former room, the emergency lights, whether normal or emergency condition is always in a state of light. Lamp type 4 representative often dark emergency lighting lamps and lanterns, commonly used in high-rise residential buildings of Ming stairwells, elevator and its former chamber evacuation instructions of lighting, this kind of emergency lights, because have natural light illumination at ordinary times, do not need light, when the accident can be forced to light fire signal. Use induction type lamps and lanterns of emergency lighting lamp 5 representative, this kind of lamps and lanterns is used in the high-rise residential stair, through induction signal light, when the accident occurred, whether induction lighting lamps and lanterns, or in a state of out, can light up. Light 6 on behalf of the evacuation indicator lights of the storage battery, this kind of lamps and lanterns is commonly used in stairwells, elevator and its former chamber evacuation instructions of lighting, its usual has dual power supply, for the battery in the lamp, when an accident, by a circuit breaker control of shunt tripping device, make its lamps and lanterns to light. Four, the conclusion of emergency lighting design is a high-rise residential building electrical design is an important part of this article, according to a new building electrical related specification for the design of a high-rise residential building emergency lighting a few questions.
