Description

The brake apparatus of high-rise building rapidly descending escape system escape apparatus

Technical field

The utility model relates to a kind of safety self-saving product, relates in particular to a kind of brake apparatus of the high-rise building rapidly descending escape system escape apparatus of fast-escape can be in danger on high-rise building time.

Background technology

Along with the development of economic society, more and more for the skyscraper of living or handling official business, make population inhabitation and working environment intensive year by year.More and more exceed 50 meters in the face of in present city, once the dangerous situation of the residential building of 100 meters, office building breaking out of fire and so on, fire-fighting can only be leaned on the extinguishing ability in building self substantially, saving oneself also substantially will be on one's own account, especially in the time that dangerous situation occurs in higher floor, aerial ladder has been difficult to be used to carry out personnel's evacuation again.In current medium or flourishing city, be equipped with according to the news that to exceed the aerial ladder of 50 meters be all very limited.In the time there is fire or other dangerous situations, the people that live or be operated in skyscraper are brought to very large danger, often cause mass casualties.

The fire risk of skyscraper, is mainly reflected in four aspects:

1.1 latent fire hazards are many, probability is large

The high-building construction cycle is long, and job site temporary fir is many, and power consumption is large, deposit inflammable, combustible material is many; And use in highrise building fundus annex mostly be the commercial function districts such as market, food and drink, amusement, main building is house, office or hotel etc., the scale of construction is large, function complexity, electrical equipment is various, and combustible is many, fire load density is large, management of fire safety is not tight, and utmost point fire hazardous, causes serious consequence.

1.2 fire spreading approach are many, speed is fast

In skyscraper, the vertical hoistway such as bad staircase, elevator, cable shaft, piping shaft, garbage chute is processed in fire separation, the airduct of ventilation, air-conditioning, smoke evacuation system and insulation material thereof, movement joint and construction reserving hole, courtyard, corridor, furred ceiling, window and the frangible glass curtain wall etc. that is heated, it is the main channel of fire spreading, under the impact of air pressure and wind speed, easily form stack effect, flue gas is spread rapidly.A building that 100 m are high, in unobstructed situation, flue gas 30 s just can be diffused into top layer along vertical pipe well.

1.3 evacuating personnel difficulties, easy injures and deaths

The skyscraper number of plies is many, and vertical range is long, internal structure complexity, and evacuating personnel is long to comparatively safe region required times such as refuge stories in ground or building, and flow of flue gas speed than evacuating personnel speed fast more than 100 times; When breaking out of fire, conventional lift power-off shuts down, and evacuating personnel is mainly that flue gas is scurried into staircase with the stream of people, has a strong impact on safe escape by stair, and because personnel concentrate, crowded trampling easily occurs; The expansion of the intensity of a fire will make emergency lighting and emergency broadcase system be paralysed because control circuit burns, and bring great difficulty to evacuation.

1.4 equipment Requirements are high, the difficulty of putting out a fire to save life and property

Skyscraper is hundreds of rice even up to tens meters; the ability of ascending a height of fire fighting truck, water supply capacity do not reach required height; helicopter relief has been subject to many-sided restrictions such as dense smoke, dust, thermal current, flight space, stopping spot, examination & approval link, relief experience; therefore when breaking out of fire, skyscraper mainly rely on inner fire fighting device and trapped personnel rationally effectively escape save oneself.On the other hand; the indoor fire-fighting water consumption of skyscraper is technology, the level of economic development current according to China; arrange by the needs of the general scale fire of putting out a fire to save life and property; obviously not enough in the time of intensity of a fire expansion, formation large area fire; need to utilize fire fighting truck to carry out supply from outdoor, but the compressive resistance of water supply equipment usually cannot meet the demands.In addition, if Fire lift is not installed in building, fire fighter can not arrive fire bed fast, and fire-fighting equipment can not supplement in time, and the impact of bungling the chance of winning a battle is puted out a fire to save life and property.The glass curtain wall fragmentation of being heated scatters, and easily causes the damage of rescue personnel's injures and deaths and fire-fighting equipment.And construction in skyscraper, owing to there is no fire separation facility, on construction material, scaffold, bamboo raft or springboard, protection network etc. are combustible, fire-fighting system facility is not yet open-minded, and lacks fire water supply, fire attack difficulty is larger.

At present, utilize the survival equipment of rope to have much for high level, and have much commercialization.But the current people of solution for high-rise building can not be satisfactory.I am coming right away below lifts several representational products, for example slow volume production of this descending lifeline of escape apparatus (JSH-100/20) of falling, and its advantage is, can Reusability, also relatively cheap in price, at present thousand yuan of left and right; But defect is decrease speed slowly can't control only have at the uniform velocity 0.16-1.5m/s(according to load-carrying 20-100 kilogram variation) too low for high-rise building escape efficiency.Because be to provide rope for oneself, so also restricted to the length of rope, generally the highest use is highly 200 meters at present again.The for example 65 years old old man in Shanghai designs its advantage of high-rise escape apparatus and is again, with low cost, can reuse equally; But defect is to be also that the highest decrease speed only has 1.5m/s because decrease speed is uncontrollable, need to use manpower to reclaim when Reusability, many people use escape efficiency low, also because provide rope for oneself, so maxi-mum height is limited.For example research and development " self-rescue escape device " maxi-mum height in Sichuan is more than 400 meter again, is that domestic state-of-the-art its advantage of skyscraper life saving system is that single escape number is many at present, and maxi-mum height is high, is 30 years service life; But defect is high cost, expensive want 300,000 yuan of left and right, cheap also wanting, is not suitable for general resident or residential building and buys 30,000 yuan of left and right.

On market, there is in a large number the series products of saving oneself of escaping, can be that this series products uses limitation a lot, for example have slow, the each single use of downhill race speed, not easy to operate, equipment cost is too high, escape efficiency is low, security reliability can not ensure etc. many defects, these are also that survival equipment is difficult to universal obstacle.
