Abstract

See full text

In order to develop a fire-protection rolling door of the type in question such that the fire resistance duration and thermal insulation are improved and increased and in particular heat transfer points extending through the door are avoided, a fire-protection rolling door is proposed which is composed of: —a rolling-door armor of profiled plates which interconnected in an articulated manner; —a sheet-shaped intermediate layer of fire-retardant and thermally insulating material; and—overlapping cover plates, which fire-protection rolling door is held, in the open state, above an opening to be closed in the event of a fire, such that the fire-protection rolling door can be guided in guide rails disposed on both sides, the sheet-shaped intermediate layer having planar carrier segments, which are covered with at least one layer of fire-retardant and thermally insulating material on both sides.
