Abstract

Translucent construction element for rigid roofing which is based on the generally known cavity plates, in particular double-web plates. These are coated with a non-combustible fabric, in particular a fabric made from glass fibres, and meet the requirements stipulated for testing in accordance with DIN 4102, parts 7 "rigid roofing" with respect to resistance to aircraft fire and radiant heat.

Description

Die Erfindung betrifft ein lichtdurchlässiges Bauteil für die harte Bedachung, das auf den allgemein bekannten Hohlkammerplatten, insbesondere Doppelstegplatten, aufbaut.The invention relates to a translucent component for hard roofing, which is based on the generally known twin-wall sheets, in particular double-wall sheets.

In den Laddesbauordnungen und in den Richtlinien für die Verwendung von brennbaren Baustoffen, wird vorge­schrieben, daß die Dachhaut gegen Flugfeuer und strahlende Wärme widerstandsfähig sein muß. Werden diese Bedingungen erfüllt, liegt eine sogenannte harte Bedachung vor.The Laddes building regulations and the guidelines for the use of flammable building materials stipulate that the roof skin must be resistant to flying flames and radiant heat. If these conditions are met, there is a so-called hard roof.

Der Einbau einer Dachhaut, die keinen ausreichenden Schutz gegen Flugfeuer und strahlende Wärme bietet, wird auf bestimmte Flächenmaße beschränkt.The installation of a roof skin that does not provide adequate protection against flying flames and radiant heat is restricted to certain area dimensions.

So darf z. B. bei Einbau von Lichtkuppeln aus Kunststoff der Anteil an der Dachfläche 20 % und bei der Kombination von Lichtbändern und Lichtkuppeln deren Gesamtanteil 30 % nicht übersteigen.So z. B. when installing plastic skylights, the share of the roof area 20% and in the combination of skylights and skylights their total share does not exceed 30%.

Wünschenswert wäre es, auch größere Dachflächen z. B. von Werkhallen mit lichtdurchlässigen Bauteilen abdecken zu können.It would be desirable to have larger roof areas such. B. of workshops with translucent components.

Bislang ist jedoch kein Bauteil (Baustoff) bekannt, das folgende Eigenschaften in sich vereint:
- beständig gegen Flugfeuer und strahlende Wärme nach DIN 4102, Teil 7 "Harte Bedachung".
- Lichtdurchlässig,τ > 40 %
- Wärmedämmend, k-Werte von 2,8 W/m²K und besser, je nach Plattengeometrie
- Großflächig verlegbar. Formate von 1,2 x 10 m sind noch problemlos zu fertigen. Größere Formate können hergestellt werden.
- je nach verwendetem Werkstoff (Kunststoff) kalt einbiegbar oder auch thermoplastisch verformbar.
- Witterungsbeständig
- Bei Bränden im Inneren des Gebäudes öffnet sich die mit diesen Elementen eingedeckte Dachfläche und ermöglicht einen Rauchabzug.So far, however, no component (building material) is known that combines the following properties:
- Resistant to flight fire and radiant heat according to DIN 4102, part 7 "hard roofing".
- Translucent, τ> 40%
- Thermal insulation, k values of 2.8 W / m²K and better, depending on the plate geometry
- Can be laid over a large area. Formats of 1.2 x 10 m can still be easily produced. Larger formats can be produced.
- Depending on the material (plastic) used, it can be cold bent or thermoplastic formed.
- Weatherproof
- In the event of a fire inside the building, the roof area covered with these elements opens and allows smoke to be extracted.

Aufgabe der Erfindung sind Bauteile, die möglichst viele dieser Eigenschaften aufweisen.The object of the invention is components which have as many of these properties as possible.

Gegenstand der Anmeldung ist ein lichtdurchlässiges Bauteil für die harte Bedachung, bestehend aus einer Hohlkammerplatte aus Kunststoff, die an der Oberseite mit einem nichtbrennbaren Gewebe, Gewirke, Gewirre oder Vlies beschichtet ist.The subject of the application is a translucent component for the hard roofing, consisting of a hollow sheet made of plastic, which is coated on the top with a non-flammable fabric, knitted fabric, knitted fabric or fleece.

Diese bestehen vorzugsweise aus Glasfasern und weisen vorteilhafterweise ein Flächengewicht von 40 bis 600 g/m², bevorzugt 80 bis 220 g/m²(Fasergewicht)auf.These preferably consist of glass fibers and advantageously have a basis weight of 40 to 600 g / m², preferably 80 to 220 g / m² (fiber weight).

Als vorteilhaft hat es sich erwiesen, dicht geschlagene Gewebe zu verwenden.
Außer aus Glasfasern kann das Gewebe, Gewirke, Gewirre oder Vlies auch aus anderen Materialien, wie z. B. Asbest, Mineralfaser und Metallen bestehen.It has proven to be advantageous to use tightly knitted fabrics.
In addition to glass fibers, the woven, knitted, crocheted or fleece can also be made of other materials, such as. B. asbestos, mineral fiber and metals exist.

Ausschlaggebend für ihre Verwendbarkeit ist, daß sie unbrennbar sind und die Lichtdurchlässigkeit der zu beschichtenden Platten nicht vollständig beseitigen.The decisive factor for their usability is that they are non-flammable and do not completely eliminate the translucency of the panels to be coated.

Als solche setzt man bevorzugt handelsübliche Hohlkammer­platten aus Polymethylmethacrylat (PMMA), Polycarbonat oder PVC ein, die gemäß DIN 4102 in die Brandklassen B1 oder B2 einzustufen sind.As such, preference is given to using commercially available twin-wall sheets made of polymethyl methacrylate (PMMA), polycarbonate or PVC, which are to be classified in fire classes B1 or B2 according to DIN 4102.

Die Gewebe, Gewirke, Gewirre oder Vliese sind vorteil­hafterweise zumindest auf der Seite, mit der sie auf den als Grundstrukturelement dienenden Hohlkammerplatten haften sollen, mit einer Schicht aus thermoplastischem Kunststoff, insbesondere Acrylat oder PVC überzogen oder aber durchtränkt.
An der dem Bauteile abgewandten Seite ist bevorzugt eine allgemein als wetterfest bekannte Folie, insbesondere PTFE oder PVF, auf das Gewebe, Gewirke, Gewirre oder Vlies aufkaschiert.
Die Beschichtung des Bauteils kann vorteilhaft auch flammenhemmende Substanzen enthalten.The woven fabrics, knitted fabrics, knitted fabrics or nonwovens are advantageously covered or impregnated with a layer of thermoplastic, in particular acrylate or PVC, at least on the side with which they are intended to adhere to the hollow chamber panels serving as the basic structural element.
On the side facing away from the component, a film generally known as weatherproof, in particular PTFE or PVF, is preferably laminated onto the woven fabric, knitted fabric, knitted fabric or fleece.
The coating of the component can advantageously also contain flame-retardant substances.

Gegenstand der Erfindung ist ebenfalls ein Verfahren zur Herstellung der Bauteile.The invention also relates to a method for producing the components.

Bevorzugt geht man so vor, daß man das nicht brennbare Gewebe, Gewirke, Gewirre oder Vlies, das insbesondere aus Glasfasern besteht, während der Herstellung der Hohlkammerplatten, die auf allgemein bekannte Weise erfolgt, in die Kalibrierung einlaufen läßt und auf der Oberseite der Platten zum Haften bringt.It is preferred to proceed in such a way that the non-combustible fabric, knitted fabric, knitted fabric or fleece, which consists in particular of glass fibers, is run into the calibration during the manufacture of the hollow chamber panels, which is carried out in a generally known manner, and on the top of the panels Sticking brings.

Dabei kommen natürlich die oben beschriebenen verschiedenen Gewebe, Gewirke, Gewirre oder Vliese zur Verwendung. Gegebenenfalls verwendet man zur Befestigung einen zusätzlichen Kleber, z. B. einen Acrylatkleber.
Der Verbund kann aber auch nach allgemein bekannten Verfahren nach der Herstellung der Hohlkammer­platte, z. B. durch Aufkleben der beschichteten Gewebe etc. mit einem Acrylat-Kleber (z. B. Agovit (R): kalthärtender Reaktionsklebstoff auf Acrylatbasis). erfolgen.Of course, the various fabrics, knitted fabrics, knitted fabrics or nonwovens described above are used. If necessary, an additional adhesive, e.g. B. an acrylate adhesive.
The composite can also by generally known methods after the manufacture of the twin-wall sheet, z. B. by sticking the coated fabric etc. with an acrylate adhesive (e.g. Agovit (R) : cold-curing reactive adhesive based on acrylate). respectively.

Die oben beschriebenen einfachen Maßnahmen führen dazu, daß die als Grundelement der erfindungsgemäßen Bauteile eingesetzten Hohlkammerplatten (Stegdoppelplatte) jetzt die Prüfung nach DIN 4102, Teil 7 "Harte Bedachung" bestehen.The simple measures described above mean that the twin-wall sheets (double-wall sheet) used as the basic element of the components according to the invention now pass the test according to DIN 4102, Part 7 "hard roofing".

Bei dieser Prüfung entzündet man eine definierte Holz­wollemenge auf der beschichteten Oberseite der Platte. Das Gewebe verhindert ein Ausbreiten des Brandes nach unten. Gleichzeitig wird der unter dem Brandherd liegende Teil der Hohlkammerplatte plastisch. Es verformt sich nach unten und entfernt sich dadurch vom Brandgeschehen. Flammen treten an der Unterseite nicht auf, brennende Teile tropfen nicht ab und die Dachfläche bleibt geschlossen. Die Forderungen gemäß DIN 4102 werden also erfüllt.This test ignites a defined amount of wood wool on the coated top of the panel. The fabric prevents the fire from spreading downwards. At the same time, the part of the twin-wall sheet under the source of the fire becomes plastic. It deforms downwards and thereby moves away from the fire. Flames do not appear on the underside, burning parts do not drip off and the roof area remains closed. The requirements according to DIN 4102 are therefore met.

Gleichzeitig vereint das neue Bauteil alle sonstigen Eigenschaften, wie sie in der Beschreibung als wünschens­wert aufgezählt werden.At the same time, the new component combines all the other properties as listed in the description as desirable.

Konstruktionen, die bislang nicht zulässig oder möglich waren, können nun ausgeführt werden.Constructions that were previously not permitted or possible can now be carried out.

Der Einbau der erfindungsgemäßen Bauteile erfolgt nach allgemein bekannten Verfahren. Dabei werden sie mit der beschichteten Seite nach außen angebracht.The components according to the invention are installed using generally known methods. They are attached with the coated side to the outside.

Eine Einschränkung auf bestimmte Geometrien ist bei dem erfindungsgemäßen Bauteil nicht vorhanden.The component according to the invention is not restricted to certain geometries.
