Description

Inflatable escape device for high-rise building

Technical Field

The utility model relates to an escape facility technical field, concretely relates to aerify escape device for high-rise building.

Background

In cities, high-rise buildings and super high-rise buildings are more and more, and once a fire disaster happens, the danger coefficient is particularly high. At present, after fire disaster happens to a high-rise, the escape mode is very limited, and the escape can be realized only through a safety passage, namely a stair escape passage under the common condition.

The escape from the stair passage cannot be realized quickly, so the evacuation is very slow. In addition, a large amount of toxic gas is generated in a fire disaster, confusion is easily caused, and high-rise fire disasters are often accompanied by the occurrence of trampling events, so that multiple injuries are caused. In addition, the worst case is that once the stair passage is blocked, a large number of people are trapped and can only wait for rescue at the window. The ladder of the large aerial ladder fire truck can rise to more than 50 meters, but the load is limited, only two or three persons can be rescued at a time, and the aerial ladder needs time to lift, so that the rescue efficiency is very low.

In order to solve the problems, the application number is CN201220092865.1, and discloses a high-altitude escape airbag type spiral channel; application number CN200710066780.X discloses an escape device for high-rise buildings; application number CN201810215730.1 discloses an inflatable high-rise escape way. The basic escape modes of the three escape facilities adopt spiral inflatable air bags for escape, so that the defects of the existing stair escape passage are overcome, and the survival probability is greatly improved. However, the above three escape facilities still have the following disadvantages:

1. the gasbag needs bearing mechanism to be fixed in high building or other places, and bearing mechanism is fixed in the high building, and it is very complicated to be fixed in the high building existence structure, can increase other structures of building simultaneously, causes the building of building to be with high costs, and the feasibility of implementation is low. The carrying mechanism can also be temporarily assembled, but the assembly requires a lot of time, greatly prolonging the rescue time.

2. The air bag is made of elastic plastic, and because the inner cavity of the air bag is communicated, if the air bag is punctured or is burnt by flame, the whole air bag can quickly deflate, and rescue cannot be performed.

3. The occurrence of fire is random and cannot be predicted. The escape facility has extremely poor flexibility and cannot adapt to random fire conditions.
