Description
Technical field
The present invention relates to technical field of fire control, and in particular to a kind of fire of high-rise building Quick rescue equipment and rescue party
Method.
Background technique
Increasingly complicated, height with skyscraper function is continuously increased, and the safe escape problem faced is also cured
Add sternness.Tradition evacuation escape of especially skyscraper when by emergency events such as fire, the attacks of terrorism, based on stair
Mode basically can not quickly and safely evacuate all personnel in building to safety zone, moreover, disabled person, old man
Stair are also difficult with limited crowds of ability to act such as pregnant woman to evacuate rapidly.
There is very big potential exploitation value in terms of vertical evacuation with its speed advantage, convenience and operability in elevator
Value, but when the case where fire occurs in building, the safety guard of elevator is easy to happen malfunction due to heated.And
The power supply line of elevator, signal transmission line are easy to be burned, will be out of service after elevator faults.If passenger is stranded sedan-chair at this time
Compartment, if rescue personnel cannot reach in time computer room, stop of suing and labouring, after fire spreading, flue gas pours in elevator shaft easily on the scene of a fire
It causes " stack effect ", people can be smoked in elevator by dense smoke poison gas at any time to choke and death by suffocation.Even if passenger can withdraw elevator
Hall is reached, if exit passageway cannot be reached by resident room in time, scene of fire can not be also detached from, still will lead to and be buried
The tragedy in the scene of a fire.Even fireman's elevator, according to " EN81-72 " fireman's elevator " ", " EN81-73 " elevator under fire condition
Performance " ", " ISO/PDTR 25743 " and about elevator be used for emergency evacuation research " ", " BS5588-part8-1988 " disability
Personnel escape's mode code fo practice " " etc. standard requirements, be all that there is fire-fighting cup with elevator, and fire-fighting cup cannot be on fire
Premised on, it is " not preventing fires " mostly, " non-watertight " design cannot achieve and occur to answer when fire as evacuation escape elevator
With.
Therefore, find new evacuation strategy, break through the limitation of existing evacuation, improve the safe escape ability of skyscraper at
For current problem in the urgent need to address.
