When passing through the emergency exit 114, the evacuee (person) pushes at least one of the left first emergency door 130a and the right first emergency door 130b of the first emergency door 130 to the left and right to exit. (114). For example, when the evacuee pushes the left first emergency door 130a to the left, the length of the connecting wire 132 provided at the upper portion of the right first emergency door 130b increases and the escape space in the emergency exit 114 increases. This occurs, and after the evacuee passes through the emergency exit 114 through the escape space, the length of the connecting wire 132 provided on the upper portion of the first emergency exit 130b on the right decreases, and the first emergency exit 130a on the left decreases. By moving to the right, the emergency exit 114 is closed. When the evacuee pushes the right first emergency door 130b to the right, it operates in reverse.

In addition, in some cases, the evacuee may escape by pushing both the left first emergency door 130a and the right first emergency door 130b of the first emergency door 130 with both hands, in this case, the first emergency door The opening and closing operations of the left first emergency door 130a and the right first emergency door 130b are the same as described above.

For reference, after opening the second emergency door 120, the first emergency door 130, and the third emergency door 140 in turn and evacuating to a safe area at the fire site, the opening / closing portion 131 of the first emergency door 130 ), The second emergency door 120, the first emergency door (120) automatically by the second weight member 126 of the second emergency door 120 and the third weight member 146 of the third emergency door 140 130) and the third emergency door 140 may return to the original position to block the emergency exit 114 in three.

Fire screen shutter 100 according to an embodiment of the present invention by the above configuration is the first emergency door 130, the second emergency door 120, the third emergency door blocking the emergency exit 114 As it is composed of three layers of 130, the gap between the emergency exit 114 and the main screen 110 is prevented from leaking fire or smoke generated at the fire site toward the evacuation direction.
