Description

Floor-mounted evacuation ladder unit with improved ladder {EVACUATION DEVICE HAVING IMPROVED COLLAPSIBLE LADDER}

The present invention relates to a floor-mounted evacuation ladder device installed on the balcony floor of a high-rise building such as an apartment to quickly evacuate to the lower floor in case of a fire such as fire.

The development of industry and the increase of population have led to the emergence of many high-rise buildings in residential culture. If a fire or other emergency situation occurs in such a high-rise building, it is necessary to evacuate through the emergency stairway. This emergency stairway is a passage of flames in case of fire, and thus it is difficult to evacuate, causing many casualties. For this purpose, the law stipulates that a mandatory escaping means must be provided for escaping in case of a crisis.

Conventionally, as a means of emergency escape, a steel bar descending along an outer wall of a building depending on a wire rope is widely used. However, these stumbling blocks are extremely difficult and dangerous for the general public to use, and they are rarely used because of their slow escape speed. Therefore, as a way of escaping in case of a fire, such as a fire from a high-rise apartment or high-rise building, it still depends on the fire ladder or rescue helicopter. However, the high-rise ladder for firefighting has a limit on the height does not develop more than a certain height, the rescue helicopter had a problem of poor accessibility.

In order to solve the above-mentioned conventional problems, recently, a floor-mounted emergency escape means, that is, a floor-mounted evacuation ladder device, is provided to provide an evacuation route so as to evacuate from a fired floor to a lower floor.
