Description

The invention relates to a thermally insulated enclosure of fire glass panes in fire protection windows, fire doors or fire walls.

Sometimes it is necessary that z. As in largely consisting of metallic materials fire doors in which non-combustible and fire-resistant materials are integrated, also the view releasing windows must be provided in the underlying spaces. This may be the case when corridors in buildings, laboratories departments, emergency rooms in tunnels or other fire-prone areas have to be separated.

The enclosures for fire-resistant glass panes must provide as high a fire resistance as possible, as afford the other components of a fire door, a fire protection window or a fire wall. However, this requires special considerations in order to keep the different stressable materials in their combination in function for a long time, if required by the fire.

According to the known prior art, a number of examples have already been proposed, from which reference should be made below.

So is after WO 2010/043 689 A1 called a wing or frame for a fire-resistant window, which is designed on the basis of PVC hollow chamber profiles, a fire protection filling and a fire-resistant glazing. Here, metallic steel angles with a further multiply bent element form a corset for supporting a window frame, wherein a plurality of fire protection plates are integrated in the window frame. The fire-resistant glazing is insulated by thermally separating materials from the bolted together metallic steel angles and is sealed by glazing beads from the outside against the frame. The construction proves to be very complicated.

The DE 78 20 900.4 proposes a fire protection window, a fire door or a fire wall, with a frame infilled with insulating glass. The surrounding the insulating glass frame is designed as a closed, thin-walled hollow profile, made of a material having a high softening point. There is a space in the frame that contains a center seal made of non-combustible material. C-shaped cover profiles form here an interior that is filled by non-combustible material. To the C-shaped cover profiles are on one side of the window glass retaining strips, which hold the insulating glass over thermally separating seals. On the opposite side, this is done via cover profiles in conjunction with non-combustible material and gaskets analog. This construction is also quite complicated.

With DE 88 00 593.3 a fire protection window is shown, which combines elements of a known fire door, a fire wall, a fire window with the requirements of the appearance of a wooden window. Such an embodiment may be required if the form of wooden windows must be maintained in remedial measures, but still a relatively high fire resistance is guaranteed. In the wooden parts of a conventional frame are here angle rails, dimensionally stable intermediate layers and an intumescent strip, the glass pane at its edges, integrated integrated. From the outside and inside, the glass is sealed with a seal.

Then be on DE 102 37 395 A1 which proposes a fire-resistant glazing and a fire-resistant window and a method for producing a fire protection composition and a fire-resistant glazing. The fire-resistant glazing here consists of two successively arranged glass plates between which there is a gap-wide gap, in which a heat radiation preventing Hydrogel is involved. This gel can be a mixture of different organic compounds.

As can be seen from the example given prior art, the named solutions either have a high design effort or they are not or not sufficiently protected against extremely high fire loads, as they are, for. B. can occur in tunnel structures for motor traffic or the railway.

The disadvantages are to be overcome by the simplest possible design measures.

It is therefore an object of the invention to provide a thermally insulated enclosure of fire glass panes in corresponding doors, windows or walls, which provides the simplest possible positive and non-positive connection to the adjoining frame or wall materials, doing a straightforward thermal separation of metallic cover shells and holding elements is given and, wherein a firm but positive connection to multi-layer fire protection material, which is contained in such a door, a wall, etc., to be produced.

The object of the invention is achieved as follows, with respect to the basic inventive idea is made to the protection claim 1.

The further embodiment of the invention is made in the claims 2 to 6.

To explain the invention further references are required.

The fire protection glass is located in its edge areas, held laterally, on the one hand on the inner door leaf in the support to a glass retaining profile, which is angled three times as a metal element in different edge length and on the other in the support on the outer door leaf via an angle stop, with his the fire filling leading leg, analogous to the width of the glass retaining profile on the inside of the fire glass, the fire glass encloses the outside. Between the said elements of the support, which consist of metallic material and the fire-resistant glass pane, there is in each case a cover band and on the outer edges of the fire-resistant glass pane a circumferential, foaming seal. The blind profile is bolted to the glass retaining profile, wherein - the blind profile forming a cavity - with its leading away from the fire glass pane legs parallel installation on the inner door leaf and defined here in case of fire is displaced. Through the aforementioned cavity a screw is covered, which reaches the inner door leaf and fixed an angle stop, are welded to the studs. A between angle stops, which are respectively mounted on the inner and on the outer door leaf and the outer edge of the fire glass pane located composite material consists of two different thickness fire protection plates, the inner stronger fire protection plate via screw with a middle plate of an outwardly z. B. Continuing fire door is firmly connected, with the latter (middle plate) is supported on fire protection panels of the door inner and outer door shell of a fire door.

The screw on the side of the inner door leaf, the studs sit on an angle stop, detects the inner door leaf and the glass retaining profile on the one hand and the screw on the side of the outer door leaf on the other hand, the outer door leaf and an angle stop, here stud bolts are mounted on the outer door leaf ,

The invention will be described below with reference to an embodiment.

This is on the 1 to 7 resorted.

Show it:

1 : Horizontal sectional view through an enclosure according to the invention of a fire-resistant glass pane

2 : A front view of sides of the door inner panel as assembly stage I

The reference numbers used are explained in a separate list of reference numerals.

To 1 the thermally insulated enclosure is shown in horizontal section, so also shown next to metallic components, non-metallic, located on the outer edge of the fire glass 1 and in the interior of a peripherally adjoining, z. B. fire wall or fire door.

On the side of the inner door leaf 2 there are welded stud bolts for a screw connection 12 with an angle stop 5 as shown in the 2 and 3 where the screw connection 12 also alternately for fixing a glass holding profile 7 , according to the 4 and 5 is used.

The bar of the screw connections 12 is by means of a blend profile 8th , which on a short angled leg of the glass retaining profile 7 screwed on, covered. The towards the inner door leaf 2 facing side of the blend profile 8th runs, after repeated bending, in a flat flat so that no firm connection to the surface of the inner door leaf 2 arises. This is shown in particular by the 6 and 7 in a meaningful way.

The fire-resistant glass pane 1 has at its edges on both sides, cover bands 17 and around its outer edges a foaming seal 10 ,

The outer door leaf 3 also carries circumferentially a number of screw connections 18 , in a similar way to the inner door leaf 2 , hereby an angle stop 6 is held, the together with the angle stop 5 a differently sized heat-insulating, in the present case, bivalve composite material 14 in his position. The bivalve composite material 14 learns in the interior of a subsequent, z. B. fire wall, another fixation via screw 11 ,

The outer door leaf 3 and the angle stop 6 support the fire-resistant glass pane 1 at the outside door edge. Flexible seals 9 respectively. 19 seal the fire glass 1 and the metallic components from each other before the passage of flue gases.

• – definierte Beweglichkeit der metallischen Bauelemente gegenüber den nichtmetallischen, z. B. den innenliegenden Brandschutzplatten, ist möglich,
