Die Erfindung betrifft eine gattungsgemässe Platte nach dem Oberbegriff des Sachanspruchs, nämlich eine Platte aus miteinander verbundenen, vorzugsweise verklebten Lagen aus Werkstoffen, mit einer mittleren Lage einer Massivholz aufweisenden Kernschicht aus Hirnholz mit zwei im wesentlichen senkrecht zu deren Holzfasern beziehungsweise Kapillaren sowie zueinander parallelen Plattenebenen, mit zumindest je einer, den äusseren Abschluss der Platte bildenden Aussenschicht beiderseits der die Kernschicht bildenden Lage, die aus einem Leichtholz mit einer Dichte von unter 250 kg/m3 besteht, und mit einer Glasfaserschicht, sowie eine gattungsgemässes Herstellungsverfahren dafür nach dem Oberbegriff des Verfahrensanspruchs, nämlich ein Verfahren zur Herstellung einer Platte aus miteinander verbundenen, vorzugsweise verklebten Lagen aus Werkstoffen, mit einer mittleren Lage einer Massivholz aufweisenden Kernschicht aus Hirnholz mit zwei im wesentlichen senkrecht zu deren Holzfasern beziehungsweise Kapillaren sowie zueinander parallelen Plattenebenen, mit zumindest je einer, den äusseren Abschluss der Platte bildenden Aussenschicht beiderseits der die Kernschicht bildenden Lage, die aus einem Leichtholz mit einer Dichte von unter 250 kg/m3 besteht, und mit einer Glasfaserschicht.The invention relates to a generic plate according to the preamble of the claim, namely a plate of interconnected, preferably bonded layers of materials, with a central layer of a solid wood core layer of end grain with two substantially perpendicular to the wood fibers or capillaries and parallel plate planes, with at least one, the outer end of the plate forming outer layer on both sides of the core layer forming layer, which consists of a light wood with a density of less than 250 kg / m 3 , and with a glass fiber layer, and a generic manufacturing method thereof according to the preamble of the method claim Namely, a method for producing a plate of interconnected, preferably bonded layers of materials, with a central layer of a solid wood core layer of end grain with two substantially perpendicular to the wood fibers bezi capillaries and plate planes parallel to one another, with at least one outer layer forming the outer surface of the plate on both sides of the layer forming the core layer, which consists of a light wood with a density of less than 250 kg / m 3 , and with a glass fiber layer.

Eine solche gattungsgemässe Platte und ein solches gattungsgemässes Herstellungsverfahren gelten als an sich bekannt ( DE 10 2008 009 478 A1 ). Diese Platten weisen nicht nur ein gutes Brandverhalten auf; sie sind überdies stabil.Such a generic plate and such a generic manufacturing method are known per se ( DE 10 2008 009 478 A1 ). These plates not only have good fire behavior; they are also stable.

Allerdings haben sie sich als nicht für den Einsatz als Bodenplatte, insbesondere für Fahrzeugboden-, Industrieboden- od. dgl. Platte geeignet herausgestellt.Indeed did not they prove to be for use as a base plate, especially for vehicle floor, industrial floor od. Like. Plate exposed exposed.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine gattungsgemässe Platte und ein gattungsgemässes Verfahren zu deren Herstellung so zu verbessern, dass die Eignung als Bodenplatte erreicht wird.Of the The invention is therefore based on the object, a generic Plate and a generic method for their preparation to improve so that the suitability is achieved as a base plate.

Diese Aufgabe wird bei einer gattungsgemässen Platte und bei einem gattungsgemässen Verfahren zu deren Herstellung nach dem Oberbegriff des Sachhauptanspruchs sowie dem Oberbegriff des Verfahrenshauptanspruchs durch deren kennzeichnende Merkmale, also bei der Platte dadurch, dass die Aussenschicht aus einem Sperrholz besteht und dass zwischen dieser und den Plattenebenen der Kernschicht eine Glasfaserschicht angeordnet ist, und bei dem Verfahren dadurch gelöst, dass die Kernschicht und die Aussenschichten über das in der Glasfaserschicht enthaltene Kunstharz unter Druck- und Temperatureinwikung miteinander durch Pressen verbunden werden.These Task is in a generic plate and at a generic method for their production after the preamble of the main claim as well as the generic term of the Main method claim by their characterizing features, ie at the plate characterized in that the outer layer of a plywood exists and that between this and the plate planes of the core layer a glass fiber layer is arranged, and in the method thereby solved that over the core layer and the outer layers the resin contained in the glass fiber layer under pressure and Temperatureinwikung be joined together by pressing.

Die Kernschicht der erfindungsgemässen Platte besteht dabei vorzugsweise aus Balsa-Hirnholz, dessen Faserrichtung senkrecht zu den zueinander parallelen Plattenebenen verläuft. Alternativ können hier aber auch Stab- und Stäbchenmittellagen zum Einsatz kommen.The Core layer of the inventive plate consists preferably made of balsa end grain, whose grain is vertical runs to the mutually parallel plate planes. Alternatively you can but here also rod and stick center layers are used come.

Die erfindungsgemässe Platte zeichnet sich durch eine hohe statische und dynamische Widerstandsfähigkeit, auch gegenüber Feuchtigkeit und durch eine hohe Oberflächenbeanspruchung bei vergleichsweise geringen Rohdichten um 315 kg/m3 aus. Ein weiterer Vorzug der Platte liegt in deren hoher Druckstabilität, für die die homogene Glasfaserschicht sowie die – vorzugsweise kreuzweise verleimten Fournierlagen – des Sperrholzes der Aussenschicht in Kombination mit der das vorzugsweise Balsa als Massivholz aufweisenden Kernschicht aus Hirnholz, dessen Holzfasern beziehungsweise Kapillaren im wesentlichen senkrecht zu den zueinander parallelen Plattenebenen verläuft, ursächlich sind. Durch den Einsatz der erfindungsgemässe Platten wird zusätzliche Beladekapazität bereitgestellt sowie teure und schwere Konstruktionen von Werkstoffen und mechanischen Apparaturen eingespart. Die Rohdichte von ca. 315 kg/m3 entspricht einer Gewichteinsparung von ca. 335 kg/m3 gegenüber bisherigen Platten. Die Bruchlast der Platten wurde auf ca. 30.000 N getestet.The inventive plate is characterized by a high static and dynamic resistance, even against moisture and by a high surface stress at relatively low densities around 315 kg / m 3 . Another advantage of the plate is its high pressure stability, for which the homogeneous glass fiber layer and - preferably cross-laminated Fournierlagen - the plywood of the outer layer in combination with the preferably balsa as solid wood having core layer of end grain, the wood fibers or capillaries substantially perpendicular to the mutually parallel plate planes runs, are causal. The use of the plates according to the invention provides additional loading capacity and saves expensive and heavy constructions of materials and mechanical equipment. The density of about 315 kg / m 3 corresponds to a weight saving of about 335 kg / m 3 compared to previous plates. The breaking load of the plates was tested to about 30,000 N.

Deshalb kann die erfindungsgemässe Platte auch mit Vorteil als Bodenplatte in Fahrzeugen, z. B. LKW-Aufliegern, aber auch in anderen Bereichen, wie z. B. Industrieböden, Hebebühnen, Schienenfahrzeuge etc. verwendet und eingesetzt werden.Therefore can the inventive plate also with advantage as Base plate in vehicles, z. As truck semi-trailers, but also in others Areas, such. B. industrial floors, lifting platforms, Rail vehicles etc. are used and used.

Mit Vorteil ist dabei die Glasfaserschicht aus einem mit Kunstharz getränkten Glasfaservlies gebildet.With The advantage here is the glass fiber layer of a soaked with synthetic resin Fiberglass fleece formed.

Wenn überdies die Aussenschicht aus einem viellagigen, kreuzweise verleimten Sperrholz besteht, ergibt sich ein inniger und damit fester Verbund der Schichten, woraus eine statisch sowie dynamisch hochbelastbare Platte resultiert.If moreover the outer layer of a multi-ply, cross-glued plywood there is an intimate and thus solid bond of the layers, resulting in a statically and dynamically heavy-duty plate.

Die Aussenschicht der Platte weist in zweckmässiger Ausgestaltung zwei Deckschichten aus Phenol-Kunstharz auf, wobei die obere der zwei Deckschichten der Aussenschicht mit einer Siebdruckbeschichtung versehen sein kann, wodurch sie besonders rutschfest wird, während die untere Oberfläche glatt sein kann.The Outer layer of the plate has an expedient configuration two cover layers of phenolic resin on, with the upper of the two outer layers of the outer layer with a screen printing coating may be provided, which makes it particularly slip resistant while the bottom surface can be smooth.

Wegen der vorgesehenen Kernschicht aus dem speziell ausgerichteten Hirnholz ist es erst überhaupt nach Lehre der Erfindung möglich, die Kernschicht und die Aussenschichten über das in der Glasfaserschicht enthaltene Kunstharz unter Druck- und Temperatureinwikung miteinander einem starken Pressdruck auszusetzen und damit innig zu verbinden.Because of the intended core layer of specially oriented end grain, it is only possible at all according to the teaching of the invention, the core layer and the outer layers on the resin contained in the glass fiber layer under pressure and Temperaturinwikung a strong Exposure pressing pressure and thus intimately connect.

Mit Vorzug ist bei einem zusätzlichen Leimauftrag, vorzugsweise im Walzenverfahren auf beide Seiten des die Glasfaserschicht bildenden, kunstharzgetränkten Glasfaservlies die Verbindung stets wasserfest ausgeführt, wodurch die Platte jeder Witterung ausgesetzt werden kann.With Preference is given to an additional glue application, preferably Rolling on both sides of the glass fiber layer forming, resin-impregnated glass fiber fleece, the connection always waterproof running, causing the plate exposed to any weather can be.

Es hat sich hierbei als vorteilhaft erwiesen, dass die Temperatur in der Leimfuge mindestens 120°C für einen Zeitraum von 4 min beim Pressen beträgt.It has proved to be advantageous in that the temperature in the glue joint at least 120 ° C for a period of time of 4 minutes during pressing.

Weitere zweckmässige Ausgestaltungen und Weiterbildungen der Erfindung sind in den restlichen Unteransprüchen gekennzeichnet.Further expedient refinements and developments of the invention are marked in the remaining subclaims.

Ein Ausführungsbeispiel für einer Platte wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert, die eine Platte in teilweise abgebrochener, perspektivischer Ansicht zeigt.One Exemplary embodiment of a plate is described below explained in more detail with reference to the drawing, the one plate in a partially broken, perspective view shows.

Die insgesamt vorzugsweise 30 mm dicke Platte 10 aus miteinander verbundenen, vorzugsweise verklebten Lagen aus Werkstoffen, ist mit einer mittleren Lage einer Massivholz aufweisenden Kernschicht 5 aus Hirnholz, insbesondere Balsa mit zwei im wesentlichen senkrecht zu deren Holzfasern beziehungsweise Kapillaren 51 sowie zueinander parallelen Plattenebenen, mit zumindest je einer, den äusseren Abschluss der Platte 10 bildenden Aussenschicht 9 beiderseits der die Kernschicht 5 bildenden Lage, die aus einem Leichtholz mit einer Dichte von unter 250 kg/m3 besteht, und mit einer Glasfaserschicht 6 versehen.The total preferably 30 mm thick plate 10 from interconnected, preferably bonded layers of materials, is having a central layer of a solid wood core layer 5 from end grain, especially balsa with two substantially perpendicular to their wood fibers or capillaries 51 as well as mutually parallel plate planes, with at least one, the outer end of the plate 10 forming outer layer 9 on both sides of the core layer 5 forming layer, which consists of a light wood with a density of less than 250 kg / m 3 , and with a glass fiber layer 6 Mistake.

Dabei besteht die Aussenschicht 9 aus einem viellagigen, kreuzweise verleimten Sperrholz und ist zwischen dieser und den Plattenebenen der Kernschicht 5 eine Glasfaserschicht, die aus einem kunstharzgetränkten Glasfaservlies gebildet ist, angeordnet.There is the outer layer 9 from a multi-ply, cross-glued plywood and is between this and the slab levels of the core layer 5 a glass fiber layer, which is formed of a Kunstharzgetränkten fiberglass mat, arranged.

Die Aussenschicht 9 ist mit zwei Deckschichten aus Phenol-Kunstharz versehen, von denen die obere eine Siebdruckbeschichtung aufweist.The outer layer 9 is provided with two topcoats of phenolic resin, the top of which has a screen-printed coating.

Wegen der vorgesehenen Kernschicht aus dem speziell ausgerichteten Hirnholz ist es erst überhaupt nach Lehre der Erfindung möglich, die Kernschicht und die Aussenschichten über das in der Glasfaserschicht enthaltene Kunstharz unter Druck- und Temperatureinwikung miteinander einem starken Pressdruck auszusetzen und damit innig zu verbinden. Der beim Pressen aufgebrachte Druck beträgt zumindest 1,0 N/mm2 und die Temperatur mindestens 120°C für einen Zeitraum von 4 min beim Pressen.Because of the intended core layer of the specially oriented end grain, it is only ever possible to teach the core layer and the outer layers via the resin contained in the glass fiber layer under pressure and Temperaturinwikung a strong pressing pressure and thus intimately connect. The pressure applied during pressing is at least 1.0 N / mm 2 and the temperature at least 120 ° C for a period of 4 minutes during pressing.

Der erfindungsgemässe Einsatz der Platte ist damit als Boden-, insbesondere für Fahrzeugboden-, Industrieboden- od. dgl. Platte prädestiniert.Of the use according to the invention of the plate is thus as ground, especially for vehicle floor, industrial floor od. Like. Plate predestined.
