Description

Technical Field

[0001] The present invention relates to the technical field of indoor fire alarm isolation, in particular to a high-rise indoor fire alarm isolation device. Background Art

[0002] Fire refers to a disaster caused by combustion that is out of control in time or space. The new standard defines fire as combustion that is out of control in time or space.

[0003] When a fire occurs in a high-rise building, escape and rescue are more difficult due to the high floors. Isolation is usually used to control the fire. Fire walls are set inside the passages on the floor. When a fire occurs, the fire walls drop to block the entrances to the passages on the floor, controlling the fire on the current floor to prevent the fire from spreading. People on the floor escape through dedicated escape passages. The floor isolation method can only prevent the fire from spreading to other floors. When a high-rise building catches fire, it can only rely on indoor fire extinguishers to control the indoor fire. It is difficult to isolate the indoor fire, and using doors and windows for isolation makes it inconvenient for indoor people to enter and escape.

[0004] Therefore, a high-rise indoor fire alarm isolation device has been developed that can isolate the indoor fire area from the outside world in the first time through flame retardant cloth and facilitate the escape of indoor personnel during isolation. Summary of the Invention
