Firefighting spray apparatus for protecting air-supported structure bottom film

Abstract

The invention discloses a firefighting spray apparatus for protecting an air-supported structure bottom film. The apparatus comprises a water main installed at the base of an air-supported structure, and a branch pipe guiding fire water of the water main to spray heads, and the spray heads rightly face the interior surface of the air-supported structure body, and spray along a normal direction of the interior surface of the air-supported structure body. The firefighting spray apparatus for protecting the air-supported structure bottom film can timely spray water when a fire hazard appears and form a water film on the interior surface of the air-supported structure body, so the air-supported structure body is protected, holes obtained through burning are avoided, the whole burnout of the air-supported structure body is avoided, and the long-period normal use of the air-supported structure is guaranteed, thereby the economy and the security of the air-supported structure are guaranteed; and the apparatus is especially suitable for air-supported structure warehouses for stacking inflammable articles, and crowded air-supported structure stadiums and museums.

Description

technical field [0001] The invention relates to an auxiliary equipment of an air-film building, in particular to a fire-fighting sprinkler device for protecting the bottom film of an air-film building. Background technique [0002] The air film building is a kind of building structure system that uses special architectural membrane materials as the shell, and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air film building and support the main body of the building. Due to its own structural characteristics, air film buildings have sufficient safety, and compared with existing ordinary buildings, they have better economy, environmental protection, comfort and construction convenience. Therefore, they are more and more popular in the construction field. attention and get more practical applications. [0003] Air film buildings are different from ordinary buildings; in case of fire, the membrane materials of air fi...

Problems solved by technology

[0003] Air film buildings are different from ordinary buildings; in case of fire, the membrane materials of air film buildings will be burned at high temperature, forming holes, resulting in a large amount of gas leakage, resulting in insufficient gas supply from the gas supply equipment to maintain the air film buildings. structure, so that the remaining pressure in the building is not enough to support the air film building body, resulting in the collapse of the air film building, the air film building after the collapse is unable to extinguish the fire inside and the air film building body is burned, resulting in an extreme waste of cost; At the same time, safety cannot be guaranteed, especially in large stadiums, resulting in serious safety hazards
