The invention relates to the field of fire safety and is intended for rapid evacuation of citizens from low-altitude (up to two storeys) buildings at fires and other emergencies. Appropriate use of the invention in medical and social institutions with the presence of people with limited mobility.

Fires in the residential sector and public buildings cause significant property damage, result in injury and loss of life. Especially dangerous fires in buildings, where the category of people with disabilities: neurologic clinics, nursing homes, medical hospitals for various purposes. the Main cause of death in this case is the inability of their rapid evacuation from the fire area.

Various methods of evacuation of people from buildings involving the use of various technical rescue devices: devices rescue bag, rope lowering devices, mounted a rescue ladders, rescue ladders (chutes), pneumatic rescue mats, stretch rescue canvases [1] and their improved counterparts: mobile units for evacuation of people from buildings [2], mobile ladder [3], ladders with equipment for evacuation [4], lifts for emergency evacuation [5], cluster set�TBA emergency evacuation [6]. The methods involve the evacuation of people only through the existing openings of the building - Windows, doors, stairs, prove difficult to use for people with disabilities categories of citizens and impossible to use when you cut off the fire escape routes. Implementation of fire safety requirements in buildings intended for social protection of the population, however, does not provide the possibility of evacuation of citizens during set time intervals.

Known window opening for evacuation [7], which is the sash that pivots outward to a horizontal position, and the ropes holding them in a horizontal position and placed on the sash attachment means for vertical evacuation from the valves. The disadvantage of this device is the impossibility of its use for the evacuation of mobility-impaired citizens.

A device for the evacuation of people with physical disabilities the stairs [8], involving the use for this purpose wheeled means of transport, moving down the ramp from the top to the bottom of the stairs. The disadvantage of this device is associated with the need to transport people with disabilities to the stairs, is equipped with a device, and the impossibility of simultaneously�about using the device several evacuees.

The analysis of the prior art did not reveal the closest equivalent, but the famous "taken as a prototype method of increasing safety of buildings through the use of wall for easy discharged panels [9], when the vent panel is lifted a certain part of the outer fence of the building. However, this method is implemented only in the event of overpressure inside the premises and does not allow to use it in a fire.

The relevance of the invention consists in the necessity of fire safety of mobility-impaired citizens.

The object of the invention is to provide a method of rapid evacuation of disabled citizens from low-altitude buildings of social protection of the population without waiting for the arrival of rescuers and simplified access of firefighters into a burning building.

The technical result is to simplify and accelerate the process of evacuating people from a burning home in the building.

Method of evacuation is based on a special fold-out wall sections of the house for the education of emergency descents from the premises of the building, while the sections are arranged by individual actuators (hydraulic, electric, pneumatic, etc.) of the automatic control system, and the team on their unfolding is fed automatically when s�evidenee level of smoke above the set. Folding wall sections are formed as one (for the first floor of the building) or multiple panels folded together (for the second floor of the building), pivotally interconnected and the inner panel is in its lower area with a floor respective floor. The fastening sections can be performed similar fastening legkousvaivaemyh sandwich panels [10] associated with the building frame using a mounting seams with steam insulating and insulating material and waterproofing tapes, wherein wall sections of the first and second floors go down on a prearranged fixed soil cushion, the height is comparable to the level of the surrounding ground surface.

The result of the invention is achieved as follows. In case of fire and you receive the command from the remote control folding wall sections are transformed into evacuation descent from the building. The sequencing of the transformation of sections of the first and second floors (for two-panel sections) shown in Fig.1 and Fig.2, respectively. When using a two-panel folding wall sections of the second floor is the angle of makespace will be α=30° (see Fig.2):

,

and to reduce the angle of the number of panels in the section should be increased.
