Description
Technical field
The present invention relates to a fire fighting device, particularly relate to a kind of fireproof isolation belt for high-rise building.
Background technology
According to " high-rise civil building design fire protection regulation ", high-rise civil building refers to residential building (comprising the house that the first floor arranges commerce services site) and the public building of building height more than 24 meters of more than ten layers and ten layers, along with national economy and social development, urbanization process is also come faster, increasing people pours into city, original built-up city, building covers higher and higher, suddenly, in the 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, while bringing people's amenities of life and Economization on land, and also under cover huge fire safety evaluating hidden danger." urban skyscraper continues to bring out, and for fire-fighting work, 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, current highrise building has building more than 18000, and the super highrise building highly more than hundred meters reaches Building more than 40.Shanghai has had all kinds of highrise building building more than 4000 at present, and wherein, super highrise building building more than 200 of more than 200 meter, becomes one of city that highrise building quantity is maximum in the world.According to the data that the Fire-Fighting Bureau under the Ministry of Public Security provides, at present, the whole nation total highrise building 19.18 more than ten thousand building, wherein highrise building 2154 building of more than 200 meters, and in quick growth.But annual national highrise building catches fire and causes direct economic loss to reach surprising nearly 10,000,000,000 yuans, what major issue was compared in impact in these several years just has " CCTV Xin Tai location BeiPeiLou fire ", " Shanghai apartment building fire ", " the large Ha fire in Jiahe, Mong Kok, Hong Kong " etc., but also causes great personnel casualty accidents.According to China's actual conditions, in fact, it is all by saving oneself that domestic construction has been caught fire substantially more than more than 20 layers buildings, and existing fire protection is nearly all helpless.When accident there occurs, the measure that we always introspect external rescue is inadequate, and never considers that the construction of " immunity " to fire of building self is not enough, does not just consider especially to the precautionary measures of outdoor naked light at all.
People summed up the fire risk of highrise building in the past, were mainly reflected in four aspects:
1. fire spreading is fast.The vertical hoistway such as staircase, elevator shaft, piping shaft, cable shaft of highrise building, if fire separation or fire prevention process bad, just looks like many towering chimneys during breaking out of fire, becomes 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 per second along staircase or other vertical pipe well diffusion velocity.As the building of 200 meters high, in unobstructed situation, about nearly half a minute, flue gas just can be diffused into top layer along vertical pipe well.
2. evacuate difficulty.Conventional lift is when breaking out of fire because the reason such as to cut off the electricity supply shuts down, and most high-rise building safe evacuation mainly by stair, and once scurry into flue gas in staircase, will have a strong impact on evacuation.
3. difficulty of putting out a fire to save life and property is large.Highrise building is even hundreds of rice up to tens meters, quite difficulty of carrying out outdoor during breaking out of fire putting out a fire to save life and property.Such as: the fire consumption of highrise building is the economic and technique level current according to China, consider by general fire scale, when forming large area fire, its fire consumption is obviously not enough, need to utilize fire fighting truck to building water supply, if do not install fire lift in building, fire fighter can not arrive fire bed in time and put out a fire to save life and property, fire-fighting equipment can not supplement at any time, all can affect and put out a fire to save life and property.
4. latent fire hazard is many.The building of some high-level synthesis, function is complicated, and combustible is many, and management of fire safety is not tight.If any building be provided with business business hall, flammable warehouse, dining room etc.; Some office buildings, hire out and use to many units, safety management disunity, once on fire, easily cause large area fire.
Cause the reason of this situation of highrise building massive losses a lot, above reason is no doubt important, forefathers sum up rear and still also have a large amount of high-rise fire event to occur after trying out, we find that there is an important phenomenon by a large amount of domestic analysis of cases: most fire is all first to scurry out building external from an inner room window, the intensity of a fire spreads fast along building external and rapidly to arrive roof, then by way of layer to ignite by the window building interior, or originally ignite in outside, and be not burn top from inside always.To trace it to its cause discovery, as the domestic high-rise civil building of inhabitation, resident always likes the combustibles objects such as waste and old no thing or packing case to stack on balcony, or be used as the highrise building of hotel or office building to pursue appearance effect, often exterior wall adopts curtain wall architecture to go along with sb. to guard him, the aluminium-plastic panel of Curtain Wall inside, structure glue, the components such as sealing joint strip are all the materials that can burn, also has the standard exactly in order to reach building energy conservation, and the product of the heat insulating material present stage of exterior wall is almost not incombustible, also a large amount of toxic gas can be produced when common polyphenyl or polyurethane material burning, substance combustion needs a large amount of comburant oxygen in addition, outdoor provides enough oxygen, sometimes wind is also had, encourage flame to wreak havoc, and outside not stop, alter outside Here it is flare and burn rapidly the place of the basic reason in Zheng Dong building.For this reality, we find present stage highrise building interior fire protection measure do not have at all Zheng Dong building fire-retardant, fire prevention, reduce loss effect, the super highrise building that frequent discovery is one more than 200 meter ten minutes less than, building top has just been burnt from firing point, the phenomenon that fire fighting truck is not also arrived in often occurs, not at all surprising.We know that ancient times, formula building in emblem had high " seal wall ", play exactly and prevent the house fire to ignite a whole courtyard, and play and prevent from one to catch fire bringing disaster to the phenomenon in full village; We also know that, when forest fire except putting out the scene of a fire, the place also do not arrived at fire is published trees and done one fire barrier.If we vertically do some isolation strip as construction measure on highrise building equally, necessary stop is carried out to the flare intensity of a fire risen, flame is controlled in the region of certain floor, for we win the time of a large amount of abundant fire extinguishing disaster relief, Evacuation, transfer property as far as possible.
