In the case of a fire due to the nature of such high-rise buildings, there is no difficulty in evacuating most of them by trying to escape through the door or emergency exit during the initial fire. However, if an evacuation route cannot be secured due to a large fire, a fall accident in which a person jumps over the railing from the veranda to avoid a fire occurs frequently.

In order to avoid fire and prevent the fall of the veranda, a brace was installed on the exterior wall of the veranda to deal with a fire, but it is difficult for ordinary people to operate it. And even if it was operated, there was a great fear of entrusting the body with one rope, and there was a problem of falling due to inexperience in operation.

Accordingly, Patent Documents 1 and 2 having a ladder structure that can quickly evacuate a large number of people to the lower floor in order to prevent an accident from falling during fire evacuation have been proposed.

Patent Document 2 is a frame box coupled to the evacuation hole of the ceiling slab of a building; an upper cover hinged to open and close the upper part of the frame box; a lower cover hinged to open and close the lower portion of the frame box; a link assembly in which the upper cover and the lower cover open or close the frame box at the same time; One end of the frame box is supported and it is folded to be built into the frame box, and when the upper cover and lower cover open the frame box, the folding ladder stretches out to the floor slab side. However, in the case of the floor fixing part installed on the floor of the lower floor in response to the folding ladder, it is very inconvenient for the occupants who usually live on the lower floor, and there is a problem that the installation and production costs are increased accordingly. .

And, for reuse, one person folds the ladder on the lower floor, and then another person receives the folded ladder from the upper floor and installs it inside the frame.
