Description
Technical field
The utility model relates to Designing of Building Water System technical field, especially relates to a kind of fire-fighting system of utilizing outdoor dry type spray system security fire-fighting and rescue.
Background technology
In city, land used is more and more nervous, and high residential building is more and more, and house is also subject to more and more attention as high fire and the difficult place of evacuating.The fire rescue of skyscraper is an international difficult problem, and it is taken precautions against fire measure and is mainly based at present inner automatic fire-fighting facility and certainly prevents saving oneself.
Civil buildings outer heat preservation system, in energy efficiency, is also to cause one of reason that fire incident takes place frequently.Energy-conservationly to fire-fighting, brought a new problem.CCTV's new address building fire in 2009, Shanghai in 2010 teacher apartment, Jiangzhou road 11.15 big fire, and feudal dynasty Wan Xin hotel, Shenyang in 2011 fire, all because outer insulation is burnt and spread in fire, burning is swift and violent, controls the condition of a fire in the short time again, implements rescue.It is A level incombustible material that Ministry of Public Security's issue in 2011 " about the notice of further clear and definite civil buildings heat insulating material for external fire supervision management relevant requirements " (being called literary composition No. 65) requires civil buildings heat insulating material for external to adopt combustibility.Within 2012, the Ministry of Public Security cancels No. 65 civilian execution, and the Ministry of Public Security is carried out in continuation, house is combined " civil buildings outer heat preservation system and decoration of exterior wall fire prevention temporary provisions " (No. (2009) 46, public logical word, the abbreviation " No. 46 files ") issuing with town and country construction portion.In No. 46 literary compositions, for the outer insulation of residential housing, there is following regulation: 1, be highly more than or equal to the building of 100m, the combustibility of its insulation material should be A level.2, be highly more than or equal to the building that 60m is less than 100m, the combustibility of its insulation material should be lower than B2 level.When adopting B2 level insulation material, every layer should arrange horizontal fire-blocking belt.3, be highly more than or equal to the building that 24m is less than 60m, the combustibility of its insulation material should be lower than B2 level.When adopting B2 level insulation material, often two-layer horizontal fire-blocking belt should be set.4, be highly less than the building of 24m, the combustibility of its insulation material should be lower than B2 level.Wherein, when adopting B2 level insulation material, every three layers should arrange horizontal fire-blocking belt.
For architectural exterior insulation system, A level is incombustible material, mainly contains rock wool and mineral wool, belong to inorganic heat insulation material, the resource-constrained of this type of material own, exterior-wall heat insulation use amount can not meet the needs of China's energy-saving fire proof far away and produce power consumption greatly, large to people's harmfulness.What at present hundred meters of following houses of China were used is all B2 level combustible material, is mainly to take the organic insulation material that polystyrene foam plastics (comprising polystyrene expanded foam plastics EPS plate and extruded polystyrene foamed material XPS plate), polyurethane and acidic phenol urea formaldehyde be representative.Organic material is heat-resisting poor, easily burning, once external wall of high-rise building breaking out of fire, the intensity of a fire will form three-dimensional fire with inside fire along exterior wall rapid spread, to fire-fighting and rescue, brings very big difficulty.In burning, produce toxic gas simultaneously, be unfavorable for trapped personnel and rescue personnel.
Looking back Shanghai " 1115 " wildfire in 2010 can find out, once skin catches fire, because outdoor oxygen is sufficient, fire burning is fierce, and the intensity of a fire rate of propagation is surprising from bottom to top.Common safety glass exterior window can only bear the temperature difference that can bear 250-300 ℃, and after glass explosion, the exterior window of the poison gas of the intensity of a fire and burning by explosion enters indoor immediately, indoorly becomes dangerous space, to trapped personnel, damages.
Yet experience and test show, automatic sprinkler system is by good fire extinguishing effect, and especially cooled flue gas temperature and remove smoke that boundless and indistinct the good results are evident, should actively promote the use of, and guarantees people life property safety.According to current design for fire protection standard " Code for fire protection design of high rise buildings " (version in 2005) GB50045-95 7.6.2 bar, stipulate: building height is no more than first class high storey building and the podium thereof of 100 meters, except swimming pool, rink, construction area be less than 5.00m2 toilet, ordinary residence, establish the indoor application room and the position should not water puted out a fire to save life and property of house of central air conditioning, automatic sprinkler system all should be set.Current standard arranges automatic sprinkler system to high-rise public building as requirements such as hotel, hotel and office buildings.Residential building in host country at present design does not all arrange extinction by automatic sprinkling system by standard.General residential building, high building especially, every layer of inhabitation amount is more, and the old house of recent two decades, and a lot of combustibles may have all been put in aisle, and likely initiation fire or cause fire spread, totally unfavorable to evacuating personnel in fire.Secondly, house resident fire does not have professional Smoke prevention instrument while occurring, and after fire occurs, survivor often just there will be the symptoms such as eyes are shed tears, had a dizzy spell, expiratory dyspnea within short several seconds, even suffocates.And have statistical report to show, in fire, because of anoxia asphyxia be poisoned to death, account for 72.5% of sum.Spray system can effectively stop flue gas to enter personnel space of living at during Initial Stage of Fire, guarantees personnel's safety.
After fire occurs, guarantor's life security is final purpose.The difficulty of rescuing after high residential building catches fire and escaping increases compared with multi-storey building difficulty, and a lot of families are because have old man and child, and evacuation is escaped more difficult, and result can only wait for rescue at home.The refuge of reasonable Arrangement indoor security, a new direction that becomes fire-fighting research and design.
Moreover, fire fighting truck generally arrives scene of fire about 20 minutes, when fire-fighting and rescue and fire extinguishing, the high altitude the most on a large scale of fire fighter's general using motor ladder and curved arm vehicle, first rescue and evacuate trapped personnel, next utilizes fixedly fire water monitor on car the expanding of the intensity of a fire outside control room to greatest extent, now as can not effectively from outside, be controlled, Zheng Dong building will become the column of flame at short notice, and outdoor fire fighting exterior wall vertical passageway rescue passage is caused to difficulty.The aerial ladder of ascending a height had now both been undertaken the task of lifting rescue, utilized again fire-fighting equipment on aerial ladder to exterior wall sprinkling fire simultaneously, therefore in rescue, intermittent fire extinguishing may make again that fire is revivable bungles the chance of winning a battle.
Another person depends merely on mobile fire-fighting equipment and supplies water to fighting position, has both consumed a large amount of manpowers and equipment, and performance difficulty, directly affects completing of combat duty again, and the external wall of high-rise building body fire of putting out a fire to save life and property also must be adhered to the operational principle of " admittedly moving combination ".And structural fire protection fire extinguishing system is all installed in building, during its design and installation, do not consider outside control fire and fire extinguishing needs, therefore helpless to external wall fire, and, therefore in design, design fixedly the fire fighting devices such as fire line is that mobile fire fighting device is created the advantage of putting out a fire.
