CONSTITUTION: A screen type fireproof shutter comprises a heat preventing seat, a heat preventing object, an exit(110), an emergency door(120), and a lower bar(130). In the heat preventing seat, spaces are formed at an interval. The heat preventing object is filled in the internal space of the heat preventing seat. The exit forms an opening in the heat preventing seat filled with the heat preventing object. In the cross section of the opening, a hanging protrusion is formed. The emergency door is inserted into the upper part of the exit. The lower bar is combined with the bottom of the heat preventing seat.
