FIRE-PROTECTION ROLLING DOOR

Abstract

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.

Claims

1. 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, which fire-protection rolling door armor is guided in guide rails on both sides and held in the open state above an opening to be closed in the event of fire, wherein the sheet-shaped intermediate layer comprises plate-shaped support segments that are covered on both sides with in each case 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.

2. The fire-protection rolling door according to claim 1, wherein the plate-shaped support segments are made of metal.

3. The fire-protection rolling door according to claim 1, wherein the plate-shaped support segments substantially extend over the width of the rolling door armor.

4. The fire-protection rolling door according to claim 1, wherein the plate-shaped support segments are adapted in height to the extension of the profiled plates.

5-8. (canceled)

9. The fire-protection rolling door according to claim 1, wherein sealing elements are arranged between mutually facing edges of adjacent plate-shaped support segments.

10. The fire-protection rolling door according to claim 1, wherein the plate-shaped support segments have a U-shaped cross section.

11. The fire-protection rolling door according to claim 1, wherein the cover plates are covered at least on one side with fire-retardant and thermally insulating material.

12. The fire-protection rolling door according to claim 1, wherein a layer of fire-retardant and thermally insulating material is placed on the profiled plates.

13. The fire-protection rolling door according to claim 12, wherein the layer of fire-retardant and thermally insulating material placed on the profiled plates is arranged in a box-shaped housing.

14. The fire-protection rolling door according to claim 1, wherein several plate-shaped support segments which are each covered on both sides with at least one layer of fire-retardant and thermally insulating material are arranged in parallel.

Description

DRAWINGS

[0021] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

[0022] Further advantages and features of the disclosure will be apparent from the following description with reference to the drawing figures wherein it is shown by:

[0023] FIG. 1 a schematic cross-section through a part of the embodiment of a fire protection rolling door according to the disclosure.

DETAILED DESCRIPTION

[0024] Example embodiments will now be described more fully with reference to the accompanying drawing.

[0025] The fire-protection rolling door 1 shown in FIG. 1 has cover plates 2 on one side, which in the embodiment shown are coated with fire-retardant and thermally insulating material 3 on the side facing the door.

[0026] On the opposite surface, profiled plates 4 are arranged which are hinged to each other to allow rolling or winding. In the embodiment shown, the profiled plates 4 on the side facing away from the door are likewise coated with fire-retardant and thermally insulating material 5, which in the embodiment shown is introduced in each case in a box-shaped housing 6.

[0027] Two intermediate layers of fire-retardant and thermally insulating material 7, 8 are arranged in the center. Plate-shaped support elements 9 are positioned between the two. In the embodiment shown, segments are formed in each case which essentially correspond to the height of the profiled plates. Seals 10 are arranged between these segments.

[0028] The profiled plates are fastened to the support element 9 by rivets 11. Rivets 12 are used to fasten the cover plates 2 to the support element 9. As can be seen, the rivets 11 and the rivets 12 are offset from each other.

[0029] The description of the embodiment serves the purpose of explanation and is not limiting.

[0030] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are inter-changeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
