Smoke prevention and exhaust supporting system for air film building and using method

Abstract

The invention discloses a smoke prevention and exhaust support system for a gas film building and a using method. The smoke prevention and exhaust support system is arranged below a film surface; under the condition of fire, a fire inspection system moves along a circular support ring rail to send a fire behavior to a control room; meanwhile, an emergency lighting device is turned on; when flue gas is gathered below the film surface, a smoke exhaust fan is started, and the high-temperature flue gas is exhausted outdoors; when an internal air pressure drops suddenly, a double-speed air supplementing fan is started, and outdoor fresh air is conveyed indoors; and when the film surface collapses to the inner surface to be in contact with a collapse support ring, a trapped person takes up an axe from storage grids to scratch the film surface, so that self-rescue escape is realized. Under a condition of wind disasters or snow disasters, the film surface is torn by strong wind or crushed by heavy snow, so that the indoor air pressure of the air film building is suddenly reduced, the emergency lighting device is turned on, and the double-speed air supplementing fan is started, so that outdoor fresh air is conveyed indoors; when the film surface collapses to be in contact with the collapse supporting ring and most of the periphery is scattered on the ground, the trapped person takes upthe axe from the storage grids to scratch the film surface, and self-rescue escape is achieved.

Description

technical field [0001] The invention relates to the technical field of building structure disaster prevention and emergency escape under disaster conditions, in particular to an anti-smoke exhaust and anti-collapse device for air-supported membrane structure buildings, especially a smoke-exhaust support system for air-supported membrane structures and Instructions. Background technique [0002] Application number: CN202010098893.3 systematically discusses the forming principle, basic composition, application fields, and professional issues of current technology of air-supported membrane structures, especially the process of membrane surface damage under fire and the personal danger caused by its characteristics. Introduced, pointing out the deficiencies of the current technology in terms of personnel safety under fire and the gaps that need to be filled urgently, and proposed a special air-supported membrane structure product for personnel safety. However, the use requireme...

AI Technical Summary

Problems solved by technology

Analysis of this technology reveals that it is not specialized in fire accidents. In a fire, the following problems can be foreseen: the gas film structure power supply unit cannot work due to power failure caused by the fire; such mechanisms are generally made of metal components, which may be due to the lack of fire protection The protection caused damage and collapse, or the side facade facing the fire source was stuck due to thermal expansion and bending; the membrane material near the roof must have softened due to contact with high-temperature flue gas compared with normal temperature, and was pierced by the supporting cross bar or damaged. The pull of the surrounding overhanging membrane surface tears at the supporting crossbar and accelerates the collapse, thereby reducing the time available for evacuation

[0011] None of them provide air-film buildings with complex escape paths for people in air-film indoor amusement parks and other fires. "Sub-safety zone" and the integrated system of breaking and escaping and the easy-to-use method combined with the function of the place

Moreover, most of them only look at one corner, showing high technical complexity, high cost and low reliability, and even misunderstandings in basic principles
