Abstract
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.
Aus der FR-A-1403655 ist eine sogenannte lichtdurchlässige "Sandwich"-Platte bekannt, deren Kern aus zueinander parallel ausgerichteten Hohlfasern aus thermoplastischem Kunststoff besteht. Senkrecht dazu ausgerichtet deckt eine dünne Folie die oberen und unteren offenen Enden der Fasern ab. Für die Festigkeit des Bauelements sorgt dann eine weitere auf dieser Folie befindliche Schicht, bestehend aus einem Gemisch von Kunststoffmaterial und Glasfasern.From FR-A-1403655 a so-called translucent "sandwich" plate is known, the core of which consists of mutually parallel hollow fibers made of thermoplastic material. Aligned vertically, a thin film covers the top and bottom open ends of the fibers. A further layer on this film, consisting of a mixture of plastic material and glass fibers, then ensures the strength of the component.
In der EP-A-0109388 wird eine Stegplatte aus Kunststoff beschrieben, bei der auf mindestens einer ihrer beiden Seiten eine Verfestigungsschicht aus einem vom Kunststoffmaterial der Stegplatte unterschiedlichem Kunststoff mit Hilfe einer Ausgleichsschicht angebracht ist.EP-A-0109388 describes a multi-wall sheet made of plastic, in which, on at least one of its two sides, a strengthening layer made of a plastic different from the plastic material of the multi-wall sheet is applied with the aid of a compensating layer.
Von keinem dieser Bauteile ist jedoch die Eignung als "harte Bedachung" bekannt, die im folgenden Text näher definiert wird.However, none of these components is known to be suitable as a "hard roof", which is defined in more detail in the text below.
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 limited 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.For example, When installing plastic skylights, the share of the roof area is 20% and when combining skylights and skylights, the 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 also have larger roof areas e.g. 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 × 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.
- - Resistant to 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 × 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 stegplatte aus Kunststoff, dadurch gekennzeichnet daß sie an der Oberseite mit einem nichtbrennbaren gegen Flugfener und Strahlungswärme beständigen gewebe beschichtet ist.The subject of the application is a translucent component for the hard roof, consisting of a multi-wall sheet made of plastic, characterized in that it is coated on the upper side with a non-flammable fabric that is resistant to flight windows and radiant heat.
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.It has proven to be advantageous to use tightly knitted fabrics.
Außer aus Glasfasern kann das Gewebe auch aus anderen Materialien, wie z.B. Asbest, Mineralfaser und Metallen bestehen.In addition to glass fibers, the fabric can also consist of other materials such as asbestos, mineral fiber and metals.
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 stegplatten 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 multi-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 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.The fabrics 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.
An der dem Bauteile abgewandten Seite ist bevorzugt eine allgemein als wetterfest bekannte Folie, insbesondere PTFE oder PVF, auf das Gewebe aufkaschiert.On the side facing away from the component, a film generally known as weatherproof, in particular PTFE or PVF, is preferably laminated onto the fabric.
Die Beschichtung des Bauteils kann vorteilhaft auch flammenhemmende Substanzen enthalten.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 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, 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 is adhered to the top of the panels.
Dabei kommen natürlich die oben beschriebenen verschiedenen Gewebe zur Verwendung. Gegebenenfalls verwendet man zur Befestigung einen zusätzlichen Kleber, z.B. einen Acrylatkleber.Of course, the various fabrics described above are used. If necessary, an additional adhesive, e.g. an acrylic adhesive.
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.However, the composite can also be produced according to generally known methods after the manufacture of the twin-wall sheet, for example by gluing the coated fabric etc. with an acrylate adhesive (for example Agovit (R) : cold-curing reaction 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 sheets) 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 plate. 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.
Auf eine Deglas-Stegdoppelplatte 16 mm, farblos wird Glasgewebe (Leinenbindung, 44 g/m²) mit 400 g Agovit 1900 aufkaschiert.Glass fabric (linen weave, 44 g / m²) with 400 g Agovit 1900 is laminated onto a 16 mm, double-layer Deglas, colorless sheet.
Darauf wird eine Deckschicht von 400 g/m² Agovit 1900 aufgebracht. Dem Agovit wurden 10% Flammschutzmittel Fyrol CEF [Tris(β-chlorethyl)phosphat] zugesetzt.A 400 g / m² Agovit 1900 top layer is applied. 10% flame retardant Fyrol CEF [tris (β-chloroethyl) phosphate] was added to the Agovit.
Wie Beispiel 1, jedoch mit Glasgewebe, Leinenbildung, von 270 g/m²As example 1, but with glass fabric, linen formation, of 270 g / m²
Wie Beispiel 1, jedoch mit Gläsgewebe, Leinenbildung, von 600 g/m²Like example 1, but with glass fabric, linen formation, of 600 g / m²
Bei der Herstellung einer Stegdoppelplatte 16 mm wird ein acrylatbeschichtetes Glasgewebe, Gesamtgewicht 270 g/m², in die Kalibrierung eingeführt und dadurch auf der Oberfläche der Stegplatte zum Haften gebracht. Haftung 2 kg/5 cm.In the manufacture of a 16 mm double-wall sheet, an acrylate-coated glass fabric, total weight 270 g / m², is introduced into the calibration and is thereby adhered to the surface of the multi-wall sheet. Adhesion 2 kg / 5 cm.
Bei der Kalibrierung handelt es sich um eine allgemein bekannte Vorrichtung, in der die noch plastische Stegplatte unter Formzuang abgekühlt wird und dadurch ihre endgültige Form erhält.Calibration is a generally known device in which the still plastic multi-wall sheet is cooled with access to the mold and thereby obtains its final shape.
Wie Beispiel 4. Es wird jedoch ein PVC beschichtetes Glasgewebe, Gesamtgewicht 770 g/m², eingeführt. Das beidseitig beschichtete Gewebe ist auf der Oberseite mit einer PVF-Folie von 25 µ Dicke kaschiert. Die Haftung auf der Stegplatte beträgt 17 kg/5 cm.As example 4. However, a PVC coated glass fabric, total weight 770 g / m², is introduced. The fabric coated on both sides is laminated on the top with a PVF film 25 µm thick. The adhesion to the multi-wall sheet is 17 kg / 5 cm.
Alle wie in den Beispielen beschreiben hergestellten Bauteile erfüllendie Anforderungen gemäß DIN 4102, Teil 7, und besitzten die weiteren in der Aufgabenstellung als wünschenswert aufgeführten Eigenschaften.All components manufactured as described in the examples meet the requirements of DIN 4102, Part 7, and have the other properties listed as desirable in the task.
