Description
Die vorliegende Erfindung bezieht sich auf eine feuerhemmende Sandwichplatte, wie sie im Oberbegriff des unabhängigen Schutzanspruchs 1 definiert ist.The present invention relates to a fire-retardant sandwich panel as defined in the preamble of independent claim 1.
Feuerhemmende Platten werden beispielsweise als Boden- oder Wandplatten in Zug- oder Tramwagons eingesetzt:, wobei unterschiedliche Plattenkonstruktionen bekannt sind. Insbesondere an Bodenplatten werden verschiedene Anforderungen wie gute Feuerhemmung, hohe Druckfestigkeit und Stabilität, niedriges Gewicht und Kostengünstigkeit gestellt, welche von herkömmlichen Platten in ihrer Kombination nur unzureichend erfüllt werden.Fire-retardant panels are used, for example, as floor or wall panels in train or tram wagons, with different panel designs being known. Floor panels in particular have to meet various requirements such as good fire retardancy, high compressive strength and stability, low weight and cost-effectiveness, which are only inadequately met by conventional panels in their combination.
Feuerhemmende, mehrlagige, abgesperrte, d.h. in der Faserrichtung sich kreuzende Holzplatten beispielsweise sind im Normalfall ausreichend druckfest, aber auch relativ schwer.Fire-retardant, multi-layered, sealed wood panels, i.e. panels that cross each other in the direction of the grain, for example, are normally sufficiently pressure-resistant, but are also relatively heavy.
Anderseits existieren auch sogenannte Sandwichplatten, die sich aus Lagen verschiedener Materialien zusammensetzen. Zwischen zwei Deckplatten ist zur Gewichtseinsparung ein wesentlich leichterer Kern angeordnet. Die bekannten Sandwichplatten sind entweder nicht ausreichend druckfest und/oder nicht rundherum feuerhemmend oder weisen einen feuerhemmenden, druckfesten Kern auf, der relativ teuer ist.On the other hand, there are also so-called sandwich panels, which are made up of layers of different materials. A much lighter core is placed between two cover panels to save weight. The known sandwich panels are either not sufficiently pressure-resistant and/or not fire-retardant all around, or have a fire-retardant, pressure-resistant core, which is relatively expensive.
Angesichts der Nachteile der bisher bekannten, oben beschriebenen feuerhemmenden Platten liegt der Erfindung dieIn view of the disadvantages of the previously known fire-retardant panels described above, the invention is based on the
folgende Aufgabe zugrunde. Zu schaffen ist eine feuerhemmende Platte der eingangs erwähnten Art, die gleichzeitig eine gute Feuerhemmung, eine hohe Druckfestigkeit und Stabilität und ein niedriges Gewicht aufweist und zudem kostengünstig ist.The aim is to create a fire-retardant panel of the type mentioned above which simultaneously offers good fire retardancy, high compressive strength and stability, is lightweight and is also cost-effective.
Diese Aufgabe wird durch die erfindungsgemässe feuerhemmende Sandwichplatte gelöst, wie sie im unabhängigen Schutzanspruch l definiert ist. Bevorzugte Ausführungsvarianten ergeben sich aus den abhängigen Schutzansprüchen.This object is achieved by the fire-retardant sandwich panel according to the invention, as defined in independent claim 1. Preferred embodiments emerge from the dependent claims.
Das Wesen der Erfindung besteht darin, dass bei einer feuerhemmenden Sandwichplatte mit einer ersten und einer zweiten Deckplatte, zwischen denen ein wesentlich leichterer Kern angeordnet ist, die Deckplatten jeweils mindestens drei miteinander verleimte, abgesperrte Holzlagen aufweisen und feuerhemmend ausgebildet sind und der Kern von feuerhemmendem Material umschlossen ist.The essence of the invention is that in a fire-retardant sandwich panel with a first and a second cover panel, between which a significantly lighter core is arranged, the cover panels each have at least three glued-together, sealed layers of wood and are fire-retardant and the core is enclosed by fire-retardant material.
Dadurch, dass der Kern von feuerhemmendem Material umschlossen ist, kann darauf verzichtet werden, ihn feuerfest auszubilden. Er kann so je nach gewählter Variante kostengünstiger und/oder mit geringerem Gewicht hergestellt werden. Dass die Deckplatten mindestens drei verleimte, abgesperrte Holzlagen umfassen, stabilisiert die Sandwichplatte und macht sie im Vergleich zu Metallplatten geräuschdämmend. Because the core is surrounded by fire-retardant material, it is not necessary to make it fireproof. Depending on the variant chosen, it can be manufactured more cost-effectively and/or with less weight. The fact that the cover panels comprise at least three glued, sealed layers of wood stabilizes the sandwich panel and makes it sound-insulating compared to metal panels.
Mit Vorteil weist der Kern eine Dichte von maximal 300 kg/m3, vorzugsweise maximal ISO kg/m3 und in senkrechter Richtung zu den Deckplatten einen &Egr;-Modul von mindestensThe core advantageously has a density of maximum 300 kg/m 3 , preferably maximum ISO kg/m 3 and in the perpendicular direction to the cover plates an &Egr;-modulus of at least

1000 N/mm2, vorzugsweise mindestens 4000 N/mm2 auf. Er besteht zu diesem Zweck beispielsweise aus Balsaholz, aus einem Schaum, der z.B. Polyetherimid, Polyurethan oder PVC beinhaltet, oder aus einer Wabenplatte, z.B. aus Aluminium s oder Aramid. Auf diese Weise kann eine hohe Druckfestigkeit bei geringem Gewicht erreicht werden.1000 N/mm 2 , preferably at least 4000 N/mm 2 . For this purpose it consists for example of balsa wood, of a foam containing eg polyetherimide, polyurethane or PVC, or of a honeycomb plate, eg made of aluminum or aramid. In this way, a high compressive strength can be achieved with low weight.
Bei einem bevorzugten Ausführungsbeispiel ist zwischen der ersten und der zweiten Deckplatte um den Kern herum eine Randleiste angeordnet, die mindestens drei miteinander verleimte Holzlagen aufweist und feuerhemmend ausgebildet ist, wobei die Randleiste vorzugsweise mit den beiden Deckplatten verleimt ist. Die ganze Sandwichplatte setzt sich so im wesentlichen nur aus verleimten Holzlagen und dem Kern zusammen. In a preferred embodiment, an edge strip is arranged between the first and second cover panels around the core, which edge strip has at least three wood layers glued together and is designed to be fire-retardant, with the edge strip preferably being glued to the two cover panels. The entire sandwich panel is thus essentially made up of glued wood layers and the core.
Die feuerhemmende Wirkung der Deckplatten und der Randleiste wird vorzugsweise durch Verwendung eines feuerhemmenden Leims, insbesondere Phenolharzleims, erzeugt, wobei hierzu beispielsweise der Leimflotte anorganische, nichtkorrosive Salze zugegeben werden. Alternativ könnten auch die Holzlagen geeignet behandelt werden.The fire-retardant effect of the cover panels and the edge strip is preferably achieved by using a fire-retardant glue, in particular phenolic resin glue, whereby inorganic, non-corrosive salts are added to the glue solution, for example. Alternatively, the wooden layers could also be treated appropriately.
Im folgenden wird die erfindungsgemässe feuerhemmende Sandwichplatte unter Bezugnahme auf die beigefügten Zeichnungen anhand eines Ausführungsbeispiels detaillierter beschrieben. Es zeigen:In the following, the fire-retardant sandwich panel according to the invention is described in more detail using an exemplary embodiment with reference to the accompanying drawings. They show:

Die dargestellte feuerhemmende Sandwichplatte umfasst eine erste Deckplatte 2, eine zweite Deckplatte 3, einen dazwischen angeordneten Kern 1 sowie eine um den Kern 1 herum zwischen der ersten Deckplatte 2 und der zweiten Deckplatte 3 angeordnete Randleiste 4. Die erste Deckplatte 2 besteht aus fünf miteinander verleimten Holzlagen 21-25, während die zweite Deckplatte 3 fünf miteinander verleimte Holzlagen 31-3 5 umfasst. An die sechs miteinander verleimte HoIzlagen 41-46 aufweisende Randleiste 4 ist von oben die Deckplatte 2 und von unten die Deckplatte 3 geleimt. Zwei benachbarte Holzlagen 21-25, 31-35, 41-46 der Deckplatte 2, der Deckplatte 3 und der Randleiste 4 kreuzen sich jeweils in der Faserrichtung des Holzes..The fire-retardant sandwich panel shown comprises a first cover panel 2, a second cover panel 3, a core 1 arranged between them and an edge strip 4 arranged around the core 1 between the first cover panel 2 and the second cover panel 3. The first cover panel 2 consists of five wood layers 21-25 glued together, while the second cover panel 3 comprises five wood layers 31-35 glued together. The cover panel 2 is glued from above to the edge strip 4, which has six wood layers 41-46 glued together, and the cover panel 3 is glued from below. Two adjacent wood layers 21-25, 31-35, 41-46 of the cover panel 2, the cover panel 3 and the edge strip 4 each cross in the direction of the wood grain.
Als Leim wird ein Phenolharzleim verwendet, der feuerhemmend .wirkt. Die Feuerhemmwirkung wird durch der Leimflotte zugegebene anorganische, nichtkorrosive Salze erzeugt.A phenolic resin glue is used as the glue, which has a fire-retardant effect. The fire-retardant effect is created by inorganic, non-corrosive salts added to the glue solution.
Je nach verwendetem Material kann für die ganze Sandwichplatte die Brandklasse S3 oder' sogar die Brandklasse S4 nach DIN 5510, 2. Teil, erreicht werden.Depending on the material used, fire class S3 or even fire class S4 according to DIN 5510, Part 2, can be achieved for the entire sandwich panel.
Der Kern 1 ist von der Deckplatte 2, der Deckplatte 3 und der Randleiste 4 vollständig umschlossen und muss deshalb nicht feuerhemmend ausgestaltet werden. Er besteht im vor-The core 1 is completely enclosed by the cover plate 2, the cover plate 3 and the edge strip 4 and therefore does not need to be designed to be fire-retardant.

Its purpose is to ensure high compressive strength with low weight.
Im vorliegenden Ausführurigsbeispiel ist der Kern 1 zwischen den Deckplatten 2, 3 von der Randleiste 4 aus mehreren Holzlagen 41-46 umschlossen.

In the present embodiment, the core 1 is enclosed between the cover plates 2, 3 by the edge strip 4 made of several layers of wood 41-46. Of course, it is also conceivable to enclose it with another fire-retardant material, such as foam or a thin cover strip.
