Prior to the description, the present invention is based on the premise that a high-rise building such as an apartment is used as an evacuation device that can be evacuated in an emergency, but the user may arbitrarily select the installation and use the building regardless of the number of the buildings It is possible. In this case, the basic condition in the process of installing the present invention is that the building floor B on which the present invention is installed should be applied to a building having strength capable of maintaining and supporting the present invention.

The lower frame 10 according to the present invention is provided with a through hole 15 so as to be movable in the center and has a step portion 14 having an outer step 11 and an inner step 13 at a side portion. The lower frame 10 is formed as a pair with the upper lid 20, which will be described later, and is formed as a rectangular thin plate. The lower frame 10 is provided with a through hole 15 through which the lower frame 10 can be moved to the center when viewed in section. The lower end of the lower frame 10 has opposite ends 11, (Not shown).

In other words, the thin plate material is folded to form the step portion 14 constituting the outer step 11 and the inner step 13 with both sides. The outer edge 11 is formed to be slightly longer than the inner edge 13. The reason for this is that the upper edge of the upper edge of the inner edge 13 of the lower frame 10 So as to adjust the height of the lower frame 10 and the upper lid 20 in the combined state.

The present invention is applied to the building floor B so as to hold the same height with the building floor B so that when the upper lid 20 is received on the lower frame 10, The height of the construction should be the same as the height at which the building floor B is installed. The through hole 15 provided at the center of the lower frame 10 is used to prevent a general escape route such as an emergency staircase and an elevator from being used or difficult when a fire or an emergency occurs, Or an emergency passage configured to evacuate to the lower layer.

The upper lid 20 according to the present invention is received on the step portion 14 of the lower frame 10 and has a handle 23 on one side so as to be opened and closed from the lower frame 10. The upper lid 20 has to have a structure in which the upper lid 20 is received and rested on the step portion 14 of the lower frame 10 precisely on the inner edge 13 so that the length of the upper lid 20 is smaller than that of the lower frame 10 . A handle 23 is provided at one side of the upper lid 20 so as to be openable and closable from the lower frame 20 and is provided opposite to the direction of the hinge means 30 described later.
