Abstract
A walk-through type fire-limiting screen arrangement separates an interior space of a building and prevents fire from propagating and assists refugees to escape from the fire. A non-combustible or fire-proof screen droops from a ceiling or a beam. At least one slit extends vertically down to a lower end of the screen to define a refugee path. A predetermined width of a closure flap is associated with the at least one slit for closing the slit with a predetermined overlap between the at least one slit and the closure flap. A main weight bar is horizontally fixed along the lower end of the screen except for the closure flap, and a sub-weight bar is horizontally fixed along the lower end of the closure flap.
