Description
Technical field
The utility model is related to a kind of life saving gas cushions, specifically, being one kind for falling from high altitude personnel and jumping out of the building certainly
Kill the lifesaving of self-inflated type air cushion of personnel rescuing.
Background technology
With increasing and depth of building the increasingly increase of skyscraper, the quantity of burst accident is increasingly
More, more stringent requirements are proposed for the lifesaving of falling of lifesaving in danger or the personnel that leap to one's own death to working at height personnel.Lifesaving gas
Pad is a kind of high altitude lifesaving equipment, is fire-fighting suitable for the ground rescue of high-rise building emergency personnel or the personnel that leap to one's own death
The safe life-saving of relief department's indispensability is equipped.Although《Fire control lifesaving air cushion》(GA 631-2006) limits its maximum rescue height
No more than 16 meters, still, in the case of other effective rescue measures, life saving gas cushion, which still be can yet be regarded as, a kind of effectively to be rescued
Nurse has, and in practice, also often there is the report that life saving gas cushion successfully gives first aid to the personnel of jumping out of the building.In general, life saving gas cushion is used with combustion-supporting
The high tensile strength fibrous material of performance is made, and internal charged pressure is slightly larger than the air of an atmospheric pressure, is a kind of closed inflation
Flexible cushion can be effectively prevented from the injures and deaths for the personnel that fall so when falling from high altitude personnel impinge upon on life saving gas cushion.But
Be, with skyscraper increase and the increase of depth of building, existing life saving gas cushion expose following deficiency in use：
(1) it falls the falling a little of personnel, is the range estimation by rescue personnel and is judged and determined, and with falling user's height
Increase, this error in judgement is very big, sometimes even catastrophic；(2) in order to improve rescue effect, life saving gas cushion should have
Sufficiently large size, still, life saving gas cushion size senior general cause inflationtime too long, and fire/jump out of the building field condition generally all
Very critical, often life saving gas cushion, which has little time to use, just has resulted in injures and deaths；(3) after life saving gas cushion inflation, it may appear that drift uses
When, usual air cushion quadrangle needs fire fighter's rope holding, occupies manpower；(4) since personnel's height of falling is higher, to lifesaving
Air cushion generates powerful impact force, which is enough to cause falling user's vertebra and cervical spine injury, meanwhile, powerful impact force can
Falling user air cushion be can be popped up, falling user and ground or other object secondary impacts caused.
