The present invention relates to a foldable fireproof screen shutter and, more specifically, to a foldable fireproof screen shutter capable of stably keeping a screen without entanglement by enabling the screen to be alternately folded forward and backward during the rise and fall of the screen. The foldable fireproof screen shutter according to the present invention comprises: a winding drum for winding a wire; a screen; front surface bars fixed at regular intervals to the front surface of the screen in a vertical direction; a wire having one end wound around the winding drum, having the other end penetrating the front surface bars, and fixed to the front bar at the lowest stage or the lower end of the screen; and rear surface bars fixed to the rear surface of the screen and placed between the front surface bars. Owing to the structure, as described above, a winding roller is not necessary, parts are not modified and a screen can be unfolded smoothly and rapidly as the screen is kept in a shutter box after being alternately folded forward and backward. Also, the screen can be installed in the shape of a closed circle when seen from the upper side and can be folded and unfolded smoothly despite installation in a circular shape. |
