Description
Technical field
The present invention relates to a fire fighting device, relate in particular to a kind of fire prevention to high buildings isolation strip.
Background technology
According to " high-rise civil building design fire protection regulation ", high-rise civil building is meant that residential building (comprising that the first floor is provided with the dwelling house of commerce services site) and the building height more than ten layers and ten layers surpasses 24 meters public building, development along with national economy and society, urbanization process is also come fast more, increasing people pours into the city, original built-up city, building covers higher and higher, suddenly, in big and medium-sized cities such as Beijing, Shanghai, a flickering high building is rised sheer from level ground like the mushrooms after rain.Profile new master fits up luxurious highrise building, when bringing people's amenities of life and saving the soil, and also under cover huge fire safety evaluating hidden danger." urban skyscraper continues to bring out, and for fire-fighting work, the fire extinguishing difficulty is increasing, and problem can not be ignored." Li Xiaodong chief fire marshal Tan Lin peak says in this way.In Beijing, present highrise building has building more than 18000, building surplus highly the super highrise building above hundred meters reaches 40.Shanghai has had all kinds of highrise buildings building more than 4000 at present, and wherein, more than 200 meter super highrise building building more than 200 becomes one of city that highrise building quantity is maximum in the world.The data that provide according to the Fire-Fighting Bureau under the Ministry of Public Security, at present, building surplus the total highrise building 19.18 ten thousand in the whole nation, Building 2154 of the highrise building more than 200 meters wherein, and in quick growth.Yet annual national highrise building catches fire and causes direct economic loss to reach surprising nearly 10,000,000,000 yuans, influence in these several years relatively major issue " CCTV's Xin Tai location BeiPeiLou fire ", " Shanghai apartment building fire ", " the big Ha fire in Jiahe, Mong Kok, Hong Kong " etc. are just arranged, but also cause great personnel casualty accidents.According to China's actual conditions, in fact, it all is by saving oneself that domestic construction surpasses more than 20 layers that building caught fire basically, and existing fire protection nearly all is powerless.When accident has taken place, it is not enough that we always introspect the measure of external rescue, and never consider the construction deficiency to " immunity " of fire of architecture-self, especially to the precautionary measures of outdoor naked light basic just do not consider.
People summed up the fire risk of highrise building in the past, were mainly reflected in four aspects:
1. fire spreading is fast.Vertical hoistway such as the staircase of highrise building, elevator shaft, piping shaft, cable shaft, bad if fire separation or fire prevention are handled, during breaking out of fire many towering chimneys, become the approach of The fire spreads quickly.According to surveying and determination, in the incipient fire stage, because of cross-ventilation, flue gas is 3 to 4 meters of per seconds along staircase or other vertical pipe well diffusion velocity.As 200 meters high buildings, under unobstructed situation, about nearly half a minute, flue gas just can be diffused into top layer along vertical pipe well.
2. evacuate difficulty.Owing to reason such as cut off the electricity supply shuts down, most high-rise building safe evacuations mainly are by stair to conventional lift when breaking out of fire, and in the staircase in case scurry into flue gas, will have a strong impact on evacuation.
3. the difficulty of putting out a fire to save life and property is big.Highrise building is up to tens meters even hundreds of rice, during breaking out of fire from the outdoor quite difficulty of putting out a fire to save life and property.For example: the fire consumption of highrise building is the economic and technique level present according to China, consider by general fire scale, when forming the large tracts of land fire, its fire consumption is obviously not enough, need utilize fire fighting truck to building water supply, if in the building fire lift is not installed, the fire fighter can not in time arrive fire bed and put out a fire to save life and property, fire-fighting equipment can not replenish at any time, all can influence and put out a fire to save life and property.
4. fire hidden danger is many.The building of some high-level synthesis, the function complexity, combustible is many, and management of fire safety is not tight.If any building be provided with commercial business hall, flammable warehouse, dining room etc.; The office building that has is hired out and is used for many units, the safety management disunity, in case on fire, cause the large tracts of land fire easily.
Cause the reason of this situation of highrise building massive losses a lot, above reason is no doubt important, still also have a large amount of high-rise fire event to occur after forefathers sum up and after trying out, we find to have an important phenomenon by a large amount of domestic analyses of cases: most fire all are room window building externals of scurrying out internally earlier, the intensity of a fire spreads fast and arrives the roof rapidly along building external, by way of the layer building interior that ignites by the window then, perhaps be exactly to ignite in the outside originally, and be not to burn the top internally always.The discovery of tracing it to its cause, domestic high-rise civil building as inhabitation usefulness, the resident always likes combustibles objects such as waste and old no thing or packing case are stacked on balcony, perhaps be used as the highrise building of hotel or office building in order to pursue appearance effect, often exterior wall employing curtain wall architecture is done and is gone along with sb. to guard him, the aluminium-plastic panel of curtain wall system inside, structure glue, members such as sealing joint strip all are the materials that can burn, also have is exactly in order to reach the standard of building energy conservation, and the product of heat insulating material present stage of exterior wall does not almost have incombustible, also can produce a large amount of toxic gases when common polyphenyl or polyurethane material burning, substance combustion needs a large amount of comburant oxygens in addition, outdoorly provide enough oxygen, sometimes also have wind, having encouraged flame wreaks havoc, and the outside do not stop, the place of flare scurries outward and burn the rapidly basic reason in whole building that Here it is.At this reality, we find that present stage highrise building interior fire protection measure does not have fire-retardant, the effect preventing fires, reduce to lose in whole building at all, often find one more than 200 meter super highrise building ten minutes less than, just burnt building top from firing point, the phenomenon that fire fighting truck is not also arrived in often takes place, and is not at all surprising.We know that ancient times, emblem formula building all had high " head of the horse wall ", play exactly to prevent a house whole courtyard that ignites that catches fire, and play and prevent that a family catches fire and bring disaster to the phenomenon in full village; We also know when forest fire except putting out the scene of a fire, also publish trees in the place that fire does not have to arrive and do the fire barrier one.If we are vertically doing some isolation strip as construction measure on the highrise building equally, the flare intensity of a fire that rises is carried out necessary stopping, flame is controlled in the zone of certain floor as far as possible, has won the time of a large amount of abundant fire extinguishing disaster relief, evacuation crowd, transfer property for us.
