The self-propelled fire escape stair in portion.
Background technique
Oneself is to be small in area but densely populated and land price is increasingly expensive in the city stayed by the current mankind, therefore that city building
Oneself is extremely widespread for high-rise building in layer, also has to have safety grounds according to high-rise building as defined in current fire codes
Survival equipment on the basis of！It always will appear building escape at regular intervals and suddenly do not cause the building fire thing that Casualties are heavy-losses arising from death and wounds
Therefore and cause to cause the main reason for dead and wounded serious mostly escape measure deficiency to be main cause；In addition to because public safety is checked simultaneously
Fail outside thorough implement, the escape measure deficiency in building itself also be can hardly absolve oneself of the blame, and such as betide Jiayi City Carnival building in the recent period
Fire it is unexpected, part victim is i.e. because escape is walked to keep away too late and hastily jump out of the building and die, therefore how in response to various no expections
Disaster such as: fire, earthquake without early warning disaster occur when, the escape problem for inhabiting the lodging personnel of high-storey is obvious
It is the answered emmetrope of occupants of building.With in current general high-storey building survival equipment, what is most generally used is exactly rope
Formula vertical landing equipment and Emergency Ladder, and the equipment Chang Yin of cable type vertical landing is not easy to operate and while hanging because climbing can generate
Rock, people dare not attempt, also not everyone can be applicable in, these devices particularly with elder person, sufferer, action not
It just is even more to be difficult to provide rapid safety escape to walk the guarantee kept away with child；In fact common people escape this kind of vertical drop
