Description

Detailed Description of the Invention The present invention provides a fire evacuation system for high-rise buildings that is configured to allow evacuees to safely evacuate from high places to the ground when an emergency accident such as a fire occurs in a normal business building such as a high-rise building. Regarding equipment.

A variety of fire evacuation devices have been proposed for high-rise buildings, including telescopic descent tubes or pipes, evacuation descent ropes, escape chutes, and folding evacuation ladders. Because there are no proper fire and smoke safety facilities in place, when a fire breaks out, the fire and smoke quickly reach the atmosphere and the appropriate windows or emergency exits, leaving evacuees in confusion, with high heat and thick smoke that threatens to suffocate. Despite enduring this, he made the evacuation equipment available for use through tears.
After putting on safety belts and other auxiliary equipment, you must bravely jump down from the window towards the ground.

Such operations are very time-consuming and require a great deal of courage to jump down, making it difficult even for young people to perform, and even more so for those who cannot do it without the help of others, such as the elderly, children, and the disabled. This was extremely dangerous, and had the drawback that people could suffocate to death by being attacked by smoke while standing next to a window before they were fully prepared. The present invention was proposed in order to eliminate the drawbacks of the conventional evacuation devices as described above, and includes an evacuation room with a fire and dust-proof structure provided on the indoor side of an emergency exit that opens on the outdoor side of a high-rise building, and an evacuation room in the evacuation room. a movable inflatable body provided to be extendable and retractable from the emergency exit toward the outdoor area via a guide track, and provided inside the inflatable body,
To provide an evacuation device for a high-rise building comprising a descending device for safely lowering an evacuee to the ground from an escape port provided at the bottom of a shelf.
