FIREPROOF SHUTTER THAT OPENS AND CLOSES WITHOUT POWER
The present disclosure provides a non-powered open/close fireproof shutter including a shutter, a shutter track which is disposed in a horizontal direction and guides both end portions of the shutter in a width direction, a coil box in which a winding shaft for winding the shutter is installed to store the shutter in a coil form, a winding motor which rotates the winding shaft, and a weight which is connected to the shutter and deploys the shutter stored in the coil box along the shutter track. The non-powered open/close fireproof shutter according to the present disclosure can significantly reduce initial facility investment and maintenance costs, prevents malfunction of the fireproof shutter, which may occur when power is lost due to a loss of an emergency power source, in advance, and can secure reliability of a fire blocking function.
