<p>The present invention relates to a fireproof screen shutter driven to prevent drooping of a shaft and to prevent overlapping of a screen to prevent fire from diffusing from an ignition point by previously blocking hazards such as flames, smokes, and toxic gases such that a fire does not spread throughout an entire building in case of a fire. The fireproof screen shutter driven to prevent drooping of a shaft and to prevent overlapping of a screen comprises: a support frame installed under a ceiling of a building; a guide frame fixated onto the support frame, moves in a lower direction from the support frame in the case of a fire in a building, partitions the inside of the building wherein the fire occurs; and a screen shutter which is provided on the support frame, inserted to the guide frame in case of fire, and moves in a downward direction. With such a configuration, the fireproof screen shutter driven to prevent drooping of a shaft and to prevent overlapping of a screen in accordance to the present invention has an effect of improving the effects of blocking heat which blocks a fire from entering an area, and prevents fire based on a spreading of high heat.</p> |
