Description

Die Erfindung betrifft ein Dach-, Decken- oder Wandelement aus mehreren aufeinander folgenden Lagen von Holzbrettern, wobei die Holzbretter der aufeinander folgenden Lagen mit ihren Breitseiten aufeinander liegen und die Holzbretter einer Lage mit den Holzbrettern zumindest der angrenzenden Lage durch Halteelemente verbunden sind.The invention relates to a roof, ceiling or wall element of several successive layers of wooden boards, wherein the wooden boards of successive layers lie with their broad sides on each other and the wooden boards are connected to a position with the wooden boards at least the adjacent layer by holding elements.

Ein solches Element ist aus DE 195 37 298 bekannt.Such an element is out DE 195 37 298 known.

Derartige Dach-, Decken- oder Wandelemente sind kostengünstig herstellbar, müssen jedoch für die Erzeugung glatter Sichtflächen vielfach nachbearbeitet werden. Werden z.B. bei der Herstellung derartiger Dach-, Decken- oder Wandelemente Holzbretter verwendet, die an den einander zugewandten Breitseiten ungehobelt sind, können an den Rändern ungleichmäßige Spalte entstehen, die besonders an der Sichtseite unerwünscht sind. Darüber hinaus stehen dann in der Regel an den Rändern Holzfasern oder Holzsplitter vor, die dem Dach-, Decken-oder Wandelement ein unschönes Aussehen verleihen. Um dies zu vermeiden, werden die Bretter vielfach auch an ihren Breitseiten gehobelt, was jedoch einen erheblichen Fertigungsaufwand erfordert. Außerdem führt das Hobeln der Bretter an den Breitseiten zu einem erheblichen Materialverlust.Such roof, ceiling or wall elements are inexpensive to produce, but must be often reworked for the production of smooth visible surfaces. If e.g. used in the production of such roof, ceiling or wall panels wooden boards, which are rude on the broad sides facing each other, uneven gaps may occur at the edges, which are undesirable especially on the visible side. In addition, wood fibers or wood splinters are usually present at the edges, giving the roof, ceiling or wall element an unattractive appearance. To avoid this, the boards are often planed on their broadsides, but this requires a considerable manufacturing effort. In addition, the planing of the boards on the broad sides leads to a considerable loss of material.

Aufgabe der Erfindung ist es, ein Dach-, Decken- oder Wandelement der eingangs genannten Art zu schaffen, das mit geringem Materialverlust aus einfachen Holzbrettern kostengünstig herstellbar ist.The object of the invention is to provide a roof, ceiling or wall element of the type mentioned, which is inexpensive to produce with little loss of material from simple wooden boards.

Diese Aufgabe wird durch ein Dach-, Decken- oder Wandelement mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a roof, ceiling or wall element with the features of claim 1. Advantageous embodiments and advantageous developments of the invention are the subject of the dependent claims.

Da beim erfindungsgemäßen Dach-, Decken oder Wandelement die Holzbretter an den einander zugewandten Breitflächen ungehobelt sind, kann nicht nur der Fertigungsaufwand verringert sondern auch ein durch Hobeln verursachter Materialverlust in der Dickenrichtung verhindert werden. Durch die spezielle Profilierung der Holzbretter an der die Sichtseite des Dach-, Decken- oder Wandelementes bildenden Schmalfläche wird außerdem erreicht, dass die Anlagekanten der aufeinander folgenden Holzbretter und ein aufgrund der Rauhigkeit der ungehobelten Breitflächen dort eventuell vorhandener ungleichmäßiger Spalt nach innen zurückversetzt und damit von außen nicht ohne weiteres sichtbar sind. Auch die an den Anlagekanten zwischen den Holzbrettern üblicherweise vorstehenden Holzfasern bzw. Holzsplitter sind nach innen zurückversetzt und nicht erkennbar. Dadurch kann auch ein großflächiges Dach-, Decken- oder Wandelement mit einer optisch ansprechenden, gleichmäßigen Sichtfläche auf relativ einfache Weise aus aufeinander gestapelten Holzbrettern mit ungehobelten Breitflächen hergestellt werden.Since in the roof, ceiling or wall element according to the invention, the wooden boards on the facing wide surfaces are rough, not only the production cost can be reduced but also caused by planing loss of material in the thickness direction can be prevented. Due to the special profiling of the wooden boards on the visible side of the roof, ceiling or wall element forming narrow surface is also achieved that the abutment edges of the successive wooden boards and a due to the roughness of unplaned broad surfaces there possibly uneven gap existing back inside and thus are not readily visible from the outside. The wood fibers or wood splinters usually protruding at the abutment edges between the wooden boards are set back inwards and can not be seen. As a result, a large-scale roof, ceiling or wall element can be produced with a visually appealing, uniform viewing surface in a relatively simple manner from stacked wooden boards with uncut wide surfaces.

In einer fertigungstechnisch vorteilhaften Ausführung sind die oberen und unteren Falze der Holzbretter an zumindest einer der in Längsrichtung der Holzbretter verlaufenden Schmalflächen als rechteckige Vertiefungen ausgebildet, so dass zwei übereinander liegende Bretter eine nach innen gehende Nut bilden, durch welche die Anlagekanten der Holzbretter nach innen zurückversetzt sind. Die abgestufte glatte Schmalfläche mit den oberen und unteren Falzen kann an einem Holzbrett zweckmäßigerweise durch einen Profilhobel oder Profilfräser in einem Arbeitsgang hergestellt werden.In a production-technically advantageous embodiment, the upper and lower folds of the wooden boards are formed on at least one of the extending in the longitudinal direction of the wooden boards narrow surfaces as rectangular depressions, so that two superimposed boards form an inwardly extending groove through which the abutment edges of the wooden boards set back inside are. The stepped smooth narrow surface with the upper and lower folds can be made on a wooden board expediently by a profile planer or profile cutter in one operation.

Zur Erreichung einer sauberen und gleichmäßigen Sichtfläche haben sich bei Deckenelementen aus 20 bis 25 mm dicken, an den Breitflächen ungehobelten Holzbrettern z.B. eine Nutbreite B von 2 bis 10 mm und eine Nuttiefe T von 3 bis 15 mm als zweckmäßig erwiesen.In order to achieve a clean and uniform viewing surface have in ceiling elements from 20 to 25 mm thick, unplaned on the broad surfaces wooden boards, for. a groove width B of 2 to 10 mm and a groove depth T of 3 to 15 mm proved to be useful.

Das Dach-, Decken- oder Wandelement kann aus gleich breiten Holzbrettern oder aus breiteren und mehreren dazwischen angeordneten schmaleren Holzbrettern aufgebaut sein, so dass zwischen den breiteren Holzbrettern ein Aufnahmeraum für ein Füll- oder Isoliermaterial entsteht. Die Aufnahmeräume können z.B. mit Beton aufgefüllt werden, wodurch ein Verbundbauteil mit guten Trag- und Festigkeitseigenschaften hergestellt werden kann.The roof, ceiling or wall element can be constructed of equal width wooden boards or from wider and more narrow wooden boards arranged therebetween, so that between the wider wooden boards a receiving space for a filling or insulating material is created. The receiving spaces may e.g. be filled with concrete, whereby a composite component with good load and strength properties can be produced.

Bei langen Dach-, Decken- oder Wandelementen sind zweckmäßigerweise innerhalb einer Lage mehrere gleich oder unterschiedlich lange Holzbretter Stoß an Stoß angeordnet. Die einzelnen Lagen können aber auch nur jeweils ein Holzbrett aufweisen.In the case of long roof, ceiling or wall elements, a plurality of wood boards of the same or different lengths are expediently arranged within one layer, butt to joint. The individual layers can also have only one wooden board at a time.

Weitere Besonderheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung. Es zeigen:

a roof, ceiling or wall element made of wooden boards in a front view, side view and top view;
FIG. 2

In den Figuren 1 und 2 ist ein Dach-, Decken- oder Wandelement 1 gezeigt, das aus mehreren aufeinander folgenden Lagen von Holzbrettern 2a bzw. 2b besteht. Die Holzbretter 2a bzw. 2b der aufeinander folgenden Lagen liegen mit ihren einander zugewandten, ungehobelten Breitflächen 3 aufeinander und sind durch z.B. als Rillennägel ausgebildete Halteelemente 4 miteinander verbunden. Bei der in den Figuren 1 und 2 gezeigten Ausführung besteht das Dach- Decken- oder Wandelement 1 aus breiteren Holzbrettern 2a und mehreren dazwischen angeordneten schmaleren Holzbrettern 2b, so dass sich zwischen den breiteren Holzbrettern 2a ein Aufnahmeraum 5 für ein Füll- oder Isoliermaterial 6 gibt. Bei dem gezeigten Ausführungsbeispiel schließen die Holzbretter 2a und 2b z.B. an einer vorderen Sichtseite bündig ab und die an der Rückseite befindlichen Aufnahmeräume 5 zwischen den breiteren Holzbrettern 2a sind mit Beton gefüllt. Dadurch kann ein Verbundbauteil mit guten Festigkeits- und Trageigenschaften hergestellt werden. Das Dach-, Decken- oder Wandelement 1 kann aber auch als reines Holzbauteil aus gleich breiten Holzbrettern 2 gefertigt sein, wie dies in Figur 3 dargestellt ist.In the Figures 1 and 2 a roof, ceiling or wall element 1 is shown, which consists of several successive layers of wooden boards 2a and 2b. The wooden boards 2a and 2b of the successive layers lie with their mutually facing, unpolished broad surfaces 3 on each other and are connected to each other by, for example, designed as a groove nails retaining elements 4. In the in the Figures 1 and 2 As shown, the roof, ceiling or wall element 1 consists of wider wooden boards 2a and a plurality of narrower wooden boards 2b arranged between them, so that there is a receiving space 5 for a filling or insulating material 6 between the wider wooden boards 2a. In the illustrated embodiment, the wooden boards 2a and 2b are flush, for example, on a front visible side, and the receiving spaces 5 located at the rear between the wider wooden boards 2a are filled with concrete. As a result, a composite component with good strength and carrying properties can be produced. The roof, ceiling or wall element 1 can also be made as a pure wood component of the same width wooden boards 2, as in FIG. 3 is shown.

Wie aus Figur 3 hervorgeht, weisen die an den Breitflächen 3 ungehobelten Holzbretter 2 des dort gezeigten Dach-, Decken- oder Wandelements 1 an ihren Längsseiten z.B. durch Hobeln hergestellte glatte Schmalflächen 7 und 8 auf. Die in Figur 3 rechten Schmalflächen 7 der Holzbretter 2 sind gerade, während die eine Sichtseite des Dach-, Decken- oder Wandelements 1 bildenden linken Schmalflächen 8 der Holzbretter 2 an ihren Rändern durch einen oberen und unteren Falz 9 bzw. 10 abgestuft sind. Zweckmäßigerweise werden die Holzbretter 2 an dieser Seite durch einen Profilhobel oder einen Profilfräser bearbeitet, der die abgestufte glatte Schmalfläche 8 mitsamt der als rechteckige Vertiefungen ausgeführten oberen und unteren Falze 9 bzw. 10 in einem Arbeitsgang erzeugt. Die beiden Falze 9 und 10 der aneinander angrenzenden Holzbretter 2 bilden so eine zur Sichtseite offene Nut 11, durch welche die Anlagekanten 12 der Holzbretter 2 und ein dort eventuell vorhandener Spalt nach innen zurückversetzt sind. Ein an den Anlagekanten 12 aufgrund der Rauheit der ungehobelten Breitflächen 3 vorhandener Spalt und dort eventuell vorstehende Holzfasern oder Holzsplitter sind daher von außen nicht erkennbar. Bei 20 bis 25 mm dicken, an den Breitflächen ungehobelten Holzbrettern haben sich z.B. eine Falzbreite b von 3 bis 15 mm und eine Falztiefe t von 1 bis 5 mm als zweckmäßig erwiesen, um bei daraus hergestellten Dach-, Decken- oder Wandelementen eine saubere und einheitliche Sichtfläche zu erreichen. Die durch die Falze 9 und 10 gebildeten Nuten 11 weisen entsprechend eine Nuttiefe T von 3 bis 15 mm und eine Nutbreite B von 2 bis 10 mm auf.How out FIG. 3 As can be seen, have the unclad on the wide surfaces 3 wooden boards 2 of the roof, ceiling or wall element 1 shown there on their long sides, for example, by smooth smooth narrow surfaces 7 and 8 produced. In the FIG. 3 right narrow surfaces 7 of the wooden boards 2 are straight, while the one visible side of the roof, ceiling or wall element 1 forming left narrow surfaces 8 of the wooden boards 2 are graded at their edges by an upper and lower fold 9 and 10 respectively. Conveniently, the wooden boards 2 are processed on this page by a profiled planer or a profile cutter, which generates the stepped smooth narrow surface 8 together with the upper and lower folds 9 and 10, which are designed as rectangular recesses, in one operation. The two folds 9 and 10 of the adjoining wooden boards 2 thus form a groove 11 open to the visible side, through which the abutment edges 12 of the wooden boards 2 and a gap possibly there after are set back inside. A at the abutment edges 12 due to the roughness of the uncouth wide surfaces 3 existing gap and there possibly protruding wood fibers or wood splinters are therefore not visible from the outside. At 20 to 25 mm thick, uncleaned on the broad surfaces wooden boards, for example, have a rebate width b of 3 to 15 mm and a rebate depth t of 1 to 5 mm proved to be useful to clean produced in roof, ceiling or wall elements to achieve a uniform visible surface. The grooves 11 formed by the folds 9 and 10 correspondingly have a groove depth T of 3 to 15 mm and a groove width B of 2 to 10 mm.

In dem vergrößerten Ausschnitt der Figur 2 ist erkennbar, dass die Holzbretter 2 jeweils einer Lage mit den Holzbrettern 2 der darauf folgenden Lage über die Halteelemente 4 verbunden sind. Diese sind gemäß Figur 1 diagonal versetzt und von Lage zu Lage auch in der Längsrichtung der Holzbretter 2 gegeneinander versetzt. Die Halteelemente 4 können dabei nicht nur in die Holzbretter 2 der angrenzenden Lage, sondern zum Teil auch noch in die Holzbretter 2 der darunter liegenden Lage eingreifen. Die Halteelemente 4 bestehen zweckmäßigerweise aus Leichtmetall oder Kunststoff, so dass das Dach-, Decken- oder Wandelement 1 auch ohne Beschädigung der empfindlichen Holzbearbeitungswerkzeuge nachbearbeitet werden kann. Die Halteelemente 4 sind zweckmäßigerweise in Form von Nägeln mit oder ohne Kopf ausgeführt, können aber auch als Klammern, Krampen o.ä. ausgebildet sein. Sie sind z.B. aus einem Aluminiumdraht herstellbar, der auf einer Rolle oder einem Coil aufgewickelt ist. Mit Hilfe einer speziellen Vorrichtung kann der Draht von der Rolle bzw. dem Coil abgewickelt, gestreckt bzw. gerichtet und auf die gewünschte Länge geschnitten werden. Die so hergestellten Halteelemente 4 können dann ohne zusätzlichen maschinellen Aufwand in ein Magazin einer Nagelvorrichtung transportiert und durch diese z.B. mit Hilfe von Druckluft in die Holzbretter 2 eingebracht werden.In the enlarged section of the FIG. 2 It can be seen that the wooden boards 2 are each connected to one layer with the wooden boards 2 of the subsequent layer via the retaining elements 4. These are according to FIG. 1 offset diagonally and offset from location to location in the longitudinal direction of the wooden boards 2 against each other. The holding elements 4 can not only engage in the wooden boards 2 of the adjacent position, but also partially in the wooden boards 2 of the underlying layer. The holding elements 4 are expediently made of light metal or plastic, so that the roof, ceiling or wall element 1 can be reworked without damaging the delicate woodworking tools. The holding elements 4 are expediently designed in the form of nails with or without head, but can also be used as staples, staples or the like. be educated. They are for example made of an aluminum wire wound on a roll or a coil. By means of a special device, the wire can be unwound from the roll or coil, stretched and cut to the desired length. The holding elements 4 thus produced can then be transported without additional mechanical effort into a magazine of a nail device and introduced through this, for example by means of compressed air in the wooden boards 2.

Die Herstellung eines vorstehend beschriebenen Dach-, Decken- oder Wandelements 1 kann dadurch erfolgen, dass auf einen Auflagetisch oder eine Unterlage zunächst eine erste Lage mit einem oder mehreren aneinander stoßenden Holzbrettern 2 aufgelegt wird. Die Holzbretter 2 werden dabei durch eine geeignete Druckvorrichtung mit der zuvor bearbeiteten, die Sichtfläche des Dach-, Decken- oder Wandelements bildenden Schmalfläche 8 an einen Seitenanschlag angedrückt. Anschließend wird auf die erste Lage eine zweite Bretterlage aufgelegt. Sofern die erste Bretterlage aus mehreren hintereinander liegenden Holzbrettern 2 besteht, sind die Stoßflächen der Holzbretter 2 in den aufeinander folgenden Lagen gegeneinander versetzt. Auch die Holzbretter 2 der zweiten Lage werden dann über die Druckvorrichtung an den Seitenanschlag angedrückt, damit die übereinander liegenden Holzbretter 2 mit ihren Schmalflächen 8 fluchten. Durch eine Spannvorrichtung werden dann die die oberen Holzbretter 2 mit ihren Breitseiten 3 auf die unteren Holzbretter 2 angepresst und mit diesen durch die z.B. als Rillennägel ausgeführten Halteelemente 4 verbunden. Die Halteelemente 4 werden z.B. durch eine automatisch gesteuerte Nagelvorrichtung eingebracht. Hierzu werden die Breite der Bretter und deren Lage beim Auflegen durch geeignete Messeinrichtungen erfasst. Aus den so ermittelten Daten kann die genaue Position der Haltestifte 6 bestimmt und die Positionierung der automatischen Nagelvorrichtung derart gesteuert werden, dass sich die unterschiedlichen Lagen eingebrachten Halteelemente nicht treffen. In entsprechender Weise können dann weitere Bretterlagen aufgelegt und über weitere Halteelemente 4 miteinander verbunden werden, bis eine gewünschte Abmessung des Dach-, Decken- oder Wandelements erreicht ist.The preparation of a roof, ceiling or wall element 1 described above can be effected by first placing a first layer with one or more abutting wooden boards 2 on a support table or a base. The wooden boards 2 are pressed by a suitable printing device with the previously processed, the visible surface of the roof, ceiling or wall element forming narrow surface 8 to a side stop. Subsequently, a second layer of boards is placed on the first layer. If the first board layer consists of several consecutive wooden boards 2, the abutting surfaces of the wooden boards 2 in the successive Layered against each other. The wooden boards 2 of the second layer are then pressed on the printing device to the side stop so that the superimposed wooden boards 2 are aligned with their narrow surfaces 8. By a clamping device then the upper wooden boards 2 are pressed with their broadsides 3 on the lower wooden boards 2 and connected to them by the running example as a grooved nails holding elements 4. The holding elements 4 are introduced, for example, by an automatically controlled nail device. For this purpose, the width of the boards and their location when placed by suitable measuring devices are detected. From the data thus determined, the exact position of the retaining pins 6 can be determined and the positioning of the automatic nail device can be controlled so that the different layers introduced holding elements do not meet. In a corresponding manner then further board layers can be placed and connected to each other via further holding elements 4 until a desired dimension of the roof, ceiling or wall element is reached.
