Description

Evacuation and rescue platform and method for refuge layers of high-rise buildings

Technical Field

The invention belongs to the technical field of evacuation and rescue, and particularly relates to an evacuation and rescue platform and method for an evacuation layer of a high-rise building.

Background

Urban land is increasingly stressed along with the continuous advancement of urban and modern processes, and the number and the height of high-rise buildings in the cities are continuously increased. In case of fire accident, high-rise buildings have a higher risk of fire due to more personnel and electric heater devices than ordinary buildings. When a fire disaster occurs in a high-rise building, the vertical evacuation distance is too long, the danger is high in the downward evacuation process of trapped people above the fire layer, and people are generally selected to be evacuated to the refuge layer to wait for rescue. However, as the fire progresses, the refuge layer remains unsafe.

At present, several main evacuation modes in high-rise buildings are as follows:

evacuation by stairs: when a fire disaster occurs, except that the firefighting elevator with the special line power supply system can still be used, the rest elevators should stop running. At this time, evacuation by stairs becomes a main evacuation method. In the fire-proof design requirements of high-rise buildings, the types of stairs are divided into four types of open stairs, closed stairs, smoke-proof stairs and outdoor hanging stairs. When fire or emergency occurs in high-rise buildings, the closed stairs and the smoke-proof stairs can only be used as evacuation stairs, the number of the evacuation stairs is effective, the evacuation time is long, and crowding and trampling are easy to occur.

Emergency evacuation with helicopter: helicopter platforms are the facilities used for rescue and berthing of helicopters in the event of fire. The building with the height of more than one hundred meters can be provided with an airplane platform, especially some large hospitals, and meanwhile, public buildings with the standard building surface of more than 1000 square meters, such as public building roofs of hotels, office buildings, comprehensive buildings and the like, are provided with helicopter parking apron or helicopter rescue facilities, but the cost for evacuation by adopting helicopters is high, required basic conditions and technical conditions are high, the evacuation capacity is limited, and the helicopter has no universality.

Emergency evacuation using fire elevators: in high-rise building fires, it is not common to use elevators for emergency evacuation, and in order to prevent the sustained spread of fires on electrical lines and equipment, non-fire electricity needs to be cut off, and none of them can be used except for fire elevators. Meanwhile, the elevator shaft can generate a chimney effect, so that the smoke in the elevator shaft can be diffused, and the casualties in the elevator shaft can be caused. Compared with a common elevator, the fire-fighting elevator which can still be used in the fire disaster has the advantages that the safety is reliable, but the fire-fighting elevator has the function of being convenient for firefighters to put out the fire disaster, and the fire-fighting elevator is used for evacuation blindly, so that the efficiency of fire rescue and personnel evacuation is greatly reduced.

Auxiliary evacuation by using self-rescue escape equipment: along with the development of scientific technology, a plurality of evacuation devices different from the traditional evacuation mode appear at home and abroad. Such as life-saving slides, unpowered circulation life-saving ladders, descending devices and the like, which are suitable for accidents that cannot be evacuated through conventional evacuation channels such as stairs and the like. However, due to the limitations of the range of use, these evacuation devices are not suitable for the evacuation of persons from high-rise building fires.

Detailed Description

The following detailed description of preferred embodiments of the invention is made in connection with the accompanying drawings, which form a part hereof, and together with the description of the embodiments of the invention, are used to explain the principles of the invention and are not intended to limit the scope of the invention.

For high-rise buildings, more people are needed, and when a fire disaster occurs, the people can be evacuated for a long time, so that the people can be evacuated safely in a short time. In order to avoid casualties, when the public building height exceeds 100 meters, a refuge layer and a refuge space should be arranged. The evacuation floor is a temporary evacuation floor adopted by personnel in the building when the high-rise building breaks out of fire and is used for meeting the requirement of temporary evacuation of evacuated personnel and waiting for fire extinguishing rescue. Therefore, for high-rise buildings, the existence of the refuge layer can strive for a great deal of time for fire-fighting and rescue, but in the traditional high-rise buildings, the refuge layer is used as a temporary refuge method, so that the rescue time of people can be only increased, and the life safety of the people cannot be guaranteed not to be threatened.
