Description
AT 401 791 BAT 401 791 B
Die Erfindung betrifft eine Verbundplatte mit wenigstens einer Deckschicht aus Holz, die vorzugsweise mit einer Unterschicht aus Holz oder aus einem Holzwerkstoff verklebt ist. Verbundplatten und Mehrschichtplatten sind in den verschiedensten Ausführungsformen bekannt und gebräuchlich. Soweit die Deckschicht derartiger Verbundplatten aus Holz besteht, handelt es sich dabei um Zuschnitte in Richtung der Holzfaser, um eine möglichst geschlossene Oberfläche zu erreichen.The invention relates to a composite panel with at least one top layer made of wood, which is preferably glued to a bottom layer made of wood or a wood-based material. Composite panels and multi-layer panels are known and used in a wide variety of embodiments. Insofar as the cover layer of such composite panels is made of wood, these are cuts in the direction of the wood fiber in order to achieve the most closed surface possible.
In anderen Anwendungsgebieten, wie z.B. bei verleimten Holzkörpern oder bei "Industrieparkett", ist es bekannt, Klötze aus Hirnholzabschnitten zu verkleben oder anderweitig miteinander zu verbinden. Dabei handelt es sich aber nicht um Plattenelemente, sondern um Massivkörper mit paralleler, zur Oberfläche hin gerichteter Faserausrichtung.In other areas of application, such as With glued wooden bodies or with " industrial parquet ", it is known to glue blocks from end grain sections or to connect them to one another in some other way. However, these are not plate elements, but rather solid bodies with a parallel fiber orientation towards the surface.
Aus der DE-34 07 055-A1 ist beispielsweise eine Parkettbodenverlege-Einheit bekannt, welche aus Holzresten kantgleiche Würfel herstellt, welche sodann zu einem Flächengebilde zusammengesetzt werden. Die einzelnen Würfel werden durch den Produktionsprozeß in bunter Folge aneinandergereiht, wodurch sich ein zufälliges Muster von Würfeln mit liegenden Fasern und von Würfeln mit stehenden, Kopfholzmusterung zeigenden Fasern ergibt. Durch diese zufällige Aneinanderreihung der Holzwürfel ergeben sich einerseits optische Nachteile, vor allem lassen sich aber solche Flächengebilde nicht als Platten verwenden, da sie eine geringe Biegefestigkeit aufweisen.From DE-34 07 055-A1, for example, a parquet floor laying unit is known which produces cube-like cubes from wood remnants, which are then assembled to form a flat structure. The individual cubes are lined up in a colorful sequence through the production process, which results in a random pattern of cubes with lying fibers and of cubes with standing fibers showing the pattern of topwood. This random arrangement of the wooden cubes results in optical disadvantages on the one hand, but above all, such flat structures cannot be used as plates, since they have a low flexural strength.
Bei Verbundplatten sind bislang im Deckschichtbereich Hirnholzabschnitte schon deshalb nicht verwendet worden, weil befürchtet wurde, dass sich dabei keine homogenen Deckschichten erzeugen lassen.For composite panels, end grain sections have not been used in the top layer area, because it was feared that it would not be possible to produce homogeneous top layers.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbundplatte zu schaffen, die bei absolut homogener Deckschicht einfach industriell herstellbar ist und dabei höhere mechanische Belastungsfähigkeit der Oberfläche aufweist als herkömmliche Verbundplatten.The invention has for its object to provide a composite panel that is easy to manufacture industrially with an absolutely homogeneous cover layer and thereby has higher mechanical strength of the surface than conventional composite panels.
Erfindungsgemäss wird diese Aufgabe in erster Linie gemäss Kennzeichen der Patentansprüche gelöst.According to the invention, this object is primarily achieved according to the characteristics of the claims.
Durch die Anordnung von Hirnholzabschnitten mit abwechselnd gegenläufiger, schräg zur Unterschicht verlaufender Hauptfaserrichtung wird erreicht, dass die Oberfläche der Hirnholzabschnitte z.B. bei einer Biegebeanspruchung nicht aufreisst, da sich die abwechselnd gegenläufigen Bahnen jeweils gegenseitig stabilisieren. Bewährt haben sich dabei Anordnungen mit einer Hauptfaserrichtung, die einen Winkel zur Ebene der Unterschicht von 15 * bis 75 · für eine Bahn und von 105 * bis 165 * für die entgegengerichtete Bahn aufweisen. Dadurch ergibt sich ein Winkel zwischen den Hauptfaserrichtungen nebeneinanderliegender Bahnen von 30* bis 150*, was zu hervorragender mechanischer Festigkeit führt. Als Nebeneffekt ergibt sich ausserdem durch die schräg geschnittenen Hirnholzabschnitte eine ansprechende Oberfläche, die durch Auswahl der Bahnbreite, Länge der Abschnitte, Wahl des Holzes und Schnittwinkel beeinflusst werden kann.The arrangement of end grain sections with alternating opposite main fiber direction, which runs obliquely to the lower layer, means that the surface of the end grain sections e.g. do not tear open under a bending load, since the alternating opposing paths stabilize each other. Arrangements with a main fiber direction that have an angle to the plane of the lower layer of 15 * to 75 * for a web and from 105 * to 165 * for the opposite web have proven successful. This results in an angle between the main fiber directions of adjacent webs of 30 * to 150 *, which leads to excellent mechanical strength. As a side effect, the diagonally cut end grain sections also result in an attractive surface, which can be influenced by the choice of web width, length of sections, choice of wood and cutting angle.
Derartige Verbundplatten können zwei oder mehrschichtig ausgebildet sein, wobei die Deckschicht z.B. eine Pressplatte, eine Sperrholzplatte oder aber vorteilhafterweise eine Anordnung von quer zur Deckschicht verlaufenden Bahnen aus Holzabschnitten sein kann, deren Hauptfaserrichtung etwa in der Ebene der Unterschicht verläuft. Dies erhöht die Steifigkeit der Gesamtanordnung besonders.Such composite panels can be formed in two or more layers, the cover layer e.g. a press plate, a plywood plate or, advantageously, an arrangement of webs which run transversely to the cover layer and consist of wood sections whose main fiber direction runs approximately in the plane of the lower layer. This particularly increases the rigidity of the overall arrangement.
Je mehr sich die Faserrichtung der Deckschicht einer Senkrechten zur Unterschicht nähert, desto belastbarer wird offensichtlich die Oberfläche. Erfindungsgemäss hat es sich dabei bewährt, bei Verwendung verschiedener Hölzer für die Deckschicht dem jeweils weicheren Holz eine Faserrichtung zu geben, die sich mehr der Senkrechten annähert (also gegen 75* b2w. gegen 105* geht) und härtere Holzschichten mit flacherer Neigung anzuordnen. Durch geschickte Auswahl der Neigungswinkel lässt sich dabei erreichen, dass die Oberflächeneigenschaften von gemischt eingesetzten Hölzern unterschiedlicher Härte derart aneinander angeglichen werden kann, dass die Oberfläche der Deckschicht im Bereich aller Holzarten etwa gleich belastbar ist und auch abgenutzt wird.The closer the fiber direction of the top layer is to a perpendicular to the bottom layer, the more resilient the surface obviously becomes. According to the invention, it has proven useful, when using different woods for the top layer, to give the softer wood a direction of the fibers that approximates the vertical (that is to say 75 * or 2 * and 105 *) and to arrange harder wood layers with a flatter slope. By skilfully selecting the angle of inclination, it can be achieved that the surface properties of mixed wood of different hardness can be matched to one another in such a way that the surface of the top layer is roughly equally resilient in all types of wood and is also worn.
Besonders vorteilhaft ist es, wenn die Bahnen immer abwechselnd jeweils in entgegengesetzter Richtung verlaufen. Es ist aber auch denkbar, jeweils zwei oder drei in die gleiche Richtung verlaufende Bahnen an zwei oder drei in die Gegenrichtung verlaufende Bahnen anstossen zu lassen. Dies ist in erster Linie eine Frage der Breite der Bahnen und der Art des verwendeten Holzes. Wesentlich ist, dass bei einer Gesamtbetrachtung der Deckschicht abwechselnd gegenläufige geneigte Faserrichtungen vorgesehen werden.It is particularly advantageous if the webs always run alternately in opposite directions. However, it is also conceivable for two or three webs running in the same direction to be abutted against two or three webs running in the opposite direction. This is primarily a question of the width of the strips and the type of wood used. It is essential that an overall view of the cover layer alternately provides opposing inclined fiber directions.
Bei Mehrschichtplatten kann selbstverständlich unter der Unterschicht eine oder mehrere weitere Schichten vorgesehen sein, die je nach Anwendungszweck entweder nur zum Gegenzug ausgebildet sind, oder ebenfalls Oberflächencharakter haben.In the case of multi-layer panels, one or more additional layers can of course be provided under the sub-layer, which depending on the application are either designed only as a counter-pull or also have a surface character.
Die neue Verbundplatte lässt sich besonders vorteilhaft im Bodenbereich auch bei starker Belastung einsetzen. Sie erlaubt z.B. die Herstellung von Parkett-Tafeln mit verschiedensten Mustern aus Weichholz mit einer Belastbarkeit, die herkömmlichem Laubholz-Parkett entspricht. Die Verbundplatte kann auch als Tischoberfläche oder Möbeloberfläche oder anderweitig, vor allem im Innenausbau eingesetzt werden. 2The new composite panel can be used particularly advantageously in the floor area even under heavy loads. It allows e.g. the production of parquet boards with a wide variety of patterns made of softwood with a load capacity that corresponds to conventional hardwood parquet. The composite panel can also be used as a table surface or furniture surface or otherwise, especially in interior construction. 2nd
