The present invention relates to a foldable horizontal smoke removal boundary wall operation device, which is installed horizontally in the lower part of the ceiling surface corresponding to the ceiling extension line, and in the event of a fire, rotates around one side of the boundary wall to form a vertical wall structure. The present invention relates to a convenient and safe horizontal smoke removal boundary wall operating device which is formed to be foldable and can be safely folded along the sliding groove of the side wall as it is folded in a normal and unfolded in case of fire.

Hazardous smoke generated when a fire occurs in a building has a high temperature, so it moves to the ceiling of the building due to convection. Since the building has a closed structure, the smoke cannot be released to the outside, and eventually the ceiling of the building As a result, it spreads rapidly, resulting in overwhelmingly more casualties due to suffocation of toxic smoke than actual burns.

Therefore, it is separated from the firewall that prevents the fire from spreading in the building is equipped with a dehumidification (smoke protection) facility.

The ventilation equipment is installed on the periphery of the ceiling or on the sidewalls to discharge or prevent the diffusion of smoke generated during a fire, and a smoke elimination damper system that absorbs and discharges smoke and a smoke elimination screen or fixed wall that delays the diffusion of the smoke for a certain time. ).

In particular, the smoke screen or the smoke boundary wall is installed inside and outside the ceiling, and serves to delay the spread of smoke along the ceiling at high speed during a fire for a certain time, and of course, a large amount of smoke spreads beyond the screen or boundary wall. It can not be prevented, but in a situation where it is not easy to evacuate quickly by evacuating the field of view and causing difficulty in breathing in a real fire, the function of the smoke barrier is proved to be quite effective, and thus it is widely used in reality.
