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.
A fire-protection rolling door composed of a rolling door armor of profiled plates which are interconnected in an articulated manner, a sheet-shaped intermediate layer of fire-retardant and thermally insulating material, and overlapping cover plates, the rolling door armor being guided in guide rails on both sides and held in an open state above an opening to be closed in the event of fire, wherein the sheet-shaped intermediate layer comprises plate-shaped support segments, each of the plate-shaped support segments being covered on both sides thereof with at least one layer of fire-retardant and thermally insulating material, wherein the plate-shaped support segments are connected to the profiled plates by means of first connecting elements and to the cover plates by means of second connecting elements, wherein the first and the second connecting elements are pin-shaped and wherein the first and the second connecting elements are offset from each other.
