Abstract

A wooden panel (1) has at least five layers which are arranged in a sheet-like fashion one above the other in the manner of a grid and the layer elements of which are arranged crosswise or parallel with respect to elements of neighbouring layers. The crosswise arrangement results in high stability and the parallel arrangement results in the wooden panel being sealed in the transverse direction. The design of the wooden panel permits the use of comparatively small-format strips or planks, and thus a cost-effective utilization of left-over wood. The wooden panel (1) can be used as a load-bearing wall element, ceiling element or roofing element. In a pre-mounting position, the wooden panel may also be divided up into a flat side plane, the part-panels then comprising in each case a part of the layers of the wooden panel. The part-panels are mounted at the mounting location, such that they face one another on the flat side, and then, together, form a wooden panel again. This configuration is particularly advantageous when erecting partition walls. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Holzbautafel für Wände, Decken oder Bedachungen und dergleichen, die mehrere, jeweils durch Einzelelemente gebildete, miteinander verbundene Schichten aufweist.The invention relates to a wooden building board for walls, ceilings or roofs and the like, which has a plurality of layers, each of which is formed by individual elements and is interconnected.

Solche Holzbautafeln sind bereits in unterschiedlichen Ausführungsformen bekannt. Sie dienen zur Rationaliserung und zur teilweisen Verlagerung des Herstellungsprozesses von der Baustelle in die Werkstatt.
Aus der EP 0 214 088 kennt man bereits ein Holzbauelement, das kastenförmig mit Außenplanken und diese verbindenden Seitenwänden ausgebildet ist. Die hier verwendeten einzelnen Bauteile sind vergleichsweise aufwendig und teuer, was sich insbesonder bei größerflächigen Formaten nachteilig auswirkt.
Such wooden building boards are already known in different embodiments. They are used for rationalization and for the partial relocation of the manufacturing process from the construction site to the workshop.
From EP 0 214 088 a wooden building element is already known which is box-shaped with outer planks and side walls connecting them. The individual components used here are comparatively complex and expensive, which has a disadvantageous effect particularly in the case of large-area formats.

Weiterhin ist aus der DE-PS 16 59 175 ein Bauelement bekannt, daß in Blockbauweise aus aufeinanderliegenden und außen verbundenen Balken gebildet ist. Dadurch ist ein praktisch massives Bauelement mit entsprechendem Gewicht vorhanden, daß schwer handhabbar ist und einen hohen Materialverbrauch bedingt.Furthermore, from DE-PS 16 59 175 a component is known that is formed in a block construction from superimposed and externally connected beams. As a result, there is a practically solid component with a corresponding weight that is difficult to handle and requires a high amount of material.

Aufgabe der vorliegenden Erfindung ist es, eine Holzbautafel der eingangs erwähnten Art zu schaffen, die gut handhabbar ist, eine hohe Stabilität und Dichtigkeit sowie gute Isolationswerte aufweist und die kostengünstig herstellbar ist. Weiterhin soll ein problemloses Verlegen von Installationsleitungen innerhalb der Holzbautafel möglich sein.The object of the present invention is to provide a wooden construction board of the type mentioned at the outset which is easy to handle, high stability and tightness and good insulation values has and which is inexpensive to manufacture. Furthermore, it should be possible to lay installation lines within the wooden building board without any problems.

Zur Lösung dieser Aufgabe wird erfindungsgemäß insbesondere vorgeschlagen, daß die Holzbautafel wenigstens fünfschichtig mit rostartig angeordneten, kreuzweisen und parallelen Schichtelementen ausgebildet ist, daß sie eine aus zueinander seitlich beabstandeten Leisten, Brettern oder dergleichen Einzelelemten gebildete Mittelschicht aufweist, deren Einzelelemente durch etwa parallele oder kreuzweise dazu angeordnete Einzelelemente beidseitig benachbarter Schichten aus zueinander seitlich beabstandeten Einzelelementen verbunden sind, daß beidseitig der Mittelschicht wenigstens zwei benachbarte Schichten mit zueinander etwa parallelen, sich längsrandseitig überlappenden, beabstandeten Einzelelementen vorgesehen sind und daß die Holzbautafel außenrandseitg eine aus unterschiedlichen Schichten gebildete Anschlußprofilierung aufweist.To solve this problem, the invention proposes, in particular, that the wooden construction board be formed at least five layers with rust-like, crosswise and parallel layer elements, that it has a middle layer formed from strips, boards or similar elements spaced apart from one another, the individual elements of which by approximately parallel or crosswise thereto arranged individual elements on both sides of adjacent layers of mutually laterally spaced individual elements are connected, that on both sides of the middle layer at least two adjacent layers are provided with mutually approximately parallel, spaced individual elements overlapping on the longitudinal edge and that the wooden panel has a connection profile formed from different layers on the outer edge.

Man kennt zwar bereits aus der DE-PS 21 48 585 ein Wandelement, bei dem zwei Mittelschichten aus parallel verlaufenden und sich randseitig teilweise überdeckenden Brettern vorhanden sind, wobei rahmenartig angeordnete Bretter zum zusätzlichen Verbinden dienen.
Solche Wandelemente lassen sich zwar für Zwischenwände bei geringen Anforderungen an Schall- und Wärmeisolation einsetzen, für statisch tragende Wände, insbesondere Außenwände, sind solche Bauelemente jedoch praktisch nicht geeignet.
One already knows from DE-PS 21 48 585 a wall element in which two middle layers of parallel and partially overlapping boards are present, frame-like boards being used for additional connection.
Although such wall elements can be used for partitions with low requirements for sound and heat insulation, such structural elements are practically not suitable for statically load-bearing walls, in particular external walls.

Die erfindungsgemäße Holzbautafel weist einerseits durch die bei einem Teil der Schichten vorgesehenen Kreuzlage der Bretter zu benachbarten Schichten eine hohe Stabilität und auch Schwindfreiheit auf und andererseits ist durch die Schichten mit parallellagigen Brettern beidseitig der Mittelschicht eine gute Abdichtung vorhanden.
Durch die parallellagigen Schichten sind auch Kanäle und Hohlräume für eine Installation bereits vorhanden, wobei diese Hohlräume auch mit zur guten Isolation beitragen.
Die durch die einzelnen Schichten gebildeten Nut- und Federanordnungen ergeben durch die Vielzahl ineinandergreifender Einzelelemente eine dichte und stabile Verbindung benachbarten Holzbautafeln.
On the one hand, the wooden construction board according to the invention has high stability and also no shrinkage due to the crosswise position of the boards in relation to adjacent layers, and on the other hand is due to the layers a good seal is provided on both sides of the middle layer with parallel-layer boards.
Due to the parallel layers, channels and cavities are already available for an installation, whereby these cavities also contribute to good insulation.
The tongue and groove arrangements formed by the individual layers result in a tight and stable connection between adjacent wooden building panels due to the large number of interlocking individual elements.

Bei einer mit fünf Schichten aufgebauten Holzbautafel ergibt sich bereits bei der erfindungsgemäßen Anordnung der Schichten und dem dabei vorgesehenen Aufbau mit den Einzelelemente eine hohe Stabilität und Isolationsfähigkeit; bevorzugt ist jedoch nach einer Weiterbildung der Erfindung vorgesehen, daß die Holzbautafel siebenschichtig mit beidseitig der Mittelschicht angeordneter, quer oder vorzugsweise parallel bezüglich der Einzelelemente angeordneter Zwischenschicht und auf dieser befindlicher, aus zwei Parallellagen bestehenden Doppelschicht ausgebildet ist.
Dadurch sind im Bereich der vorzugsweise durch horizontal verlaufende Bretter oder Leisten gebildeten Mittelschicht sowie beidseitig davon quer verlaufende Kanäle und in den weiter außenliegenden Schichten Vertikalkanäle gebildet, die eine problemlose Verlegung von Installationsleitungen ermöglichen.
Die Stabilität ist bei diesem Aufbau so groß, daß diese Holzbautafeln für die Konstruktion tragender Wände einsetzbar sind.
Trotz der guten, mit einer massiven Blockbauweise vergleichbaren Festigkeit ist eine erhebliche Materialeinsparung und damit auch eine Gewichtsreduzierung vorhanden. Gegenüber einem Mauerwerk ergibt sich bei sonst etwa vergleichbaren Werten eine ganz erhebliche Volumenreduzierung, die dem verfügbaren Raumvolumen zugute kommt.
In the case of a wooden building board constructed with five layers, the arrangement of the layers according to the invention and the structure provided with the individual elements result in high stability and insulation capability; However, according to a further development of the invention, it is preferably provided that the wooden building board is formed in seven layers with an intermediate layer arranged on both sides of the middle layer, transversely or preferably parallel with respect to the individual elements and on this double layer consisting of two parallel layers.
As a result, channels are formed in the area of the middle layer, which is preferably formed by horizontally running boards or strips, as well as channels running transversely on both sides thereof, and vertical channels in the layers lying further outward, which enable installation lines to be laid without problems.
The stability of this structure is so great that these wooden panels can be used for the construction of load-bearing walls.
Despite the good strength, which is comparable to a solid block construction, there is considerable material savings and thus a reduction in weight. Compared to masonry, otherwise comparable values result in a very considerable volume reduction, which benefits the available room volume.

Die Einzelelemente können bevorzugt aus ein bis drei Meter langen Brettern, vorzugsweise sogenannten Kürzungsbrettern bestehen. Dabei können die Bretter für die Einzelelemente eine Dicke von etwa 1 cm bis etwa 4 cm, vorzugsweise etwa 2,4 cm und eine Breite von etwa 6 bis 16 cm, vorzugsweise etwa 12 cm haben.
Die einzelnen Schichten sind somit aus einer Vielzahl vergleichsweise kleinformatiger Einzelelemte aufgebaut, was die Verwendung von kostengünstigem Restholz und damit insgesamt eine kostengünstige Herstellung der Holzbautafel ermöglicht.
The individual elements can preferably consist of one to three meter long boards, preferably so-called shortening boards. The boards for the individual elements can have a thickness of approximately 1 cm to approximately 4 cm, preferably approximately 2.4 cm and a width of approximately 6 to 16 cm, preferably approximately 12 cm.
The individual layers are thus made up of a large number of comparatively small-sized individual elements, which enables the use of inexpensive residual wood and thus an overall cost-effective production of the wooden building board.

Die einzelnen Schichten 2 bis 8 einer Holzbauplatte 1 bestehen jeweils aus zueinander in Parallellage beabstandeten, aus Brettern oder Leisten gebildeten Einzelelementen 9, die jeweils durch Einzelelemente einer benachbarten Schicht verbunden sind. Dies kann beispielsweise durch parallel zu den Einzelelementen der einen Schicht verlaufende Einzelelemente der benachbarten Schicht oder aber durch rechtwinklig dazu verlaufende, kreuzende Einzelelemente erfolgen.
Im Ausführungsbeispiel sind die beiden Außenlagen 2,3 sowie 7,8 mit in Parallellage verlaufenden Einzelelementen 9 versehen, wobei sich die Einzelelmente der benachbarten Schichten jeweils längsrandseitig bereichsweise überlappen. Dies ist besonders gut in Fig. 1 und 4 erkennbar.
Durch die parallellagigen, äußeren Doppelschichten 2,3 und 7,8 ist die Holzbautafel an ihren Außenseiten dicht verschlossen, was Voraussetzung für eine gute Wärme- und Geräuschisolation ist.
The individual layers 2 to 8 of a wooden building board 1 each consist of individual elements 9 spaced apart from one another in parallel, formed from boards or strips, which are each connected by individual elements of an adjacent layer. This can be done, for example, by individual elements of the adjacent layer running parallel to the individual elements of the one layer, or by crossing individual elements running at right angles thereto.
In the exemplary embodiment, the two outer layers 2, 3 and 7, 8 are provided with individual elements 9 running in a parallel position, the individual elements of the adjacent layers overlapping in regions overlap along the longitudinal edges. This can be seen particularly well in FIGS. 1 and 4.
Due to the parallel, outer double layers 2, 3 and 7, 8 the wooden building board is tightly sealed on the outside, which is a prerequisite for good heat and noise insulation.

Die Mittelschicht 5 sowie die beiden benachbarten Zwischenschichten 4 und 6 sind ebenfalls in Parallellage bezüglich ihrer Einzelelemente 9 ausgebildet, wobei hier jedoch die Einzelelemente quer zu denen der äußeren Doppelschichten verlaufen. Durch diesen Kreuzverband ist eine hohe Stabilität vorhanden, die eine zweidimensionale, kreuzweise Kräfteübertragung sowohl für Normal- als auch für Biegekräfte ermöglicht. Es ergibt sich hierbei auch eine hohe Scheibensteifigkeit. Weiterhin wird dadurch ein Verwinden der Holzbautafeln und ein Schwund in der Länge und in der Breite vermieden.
In der schichtweise aufgebrochenen Darstellung gemäß Figur 5 sind die einzelnen Schichten 2 bis 8 und deren Zuordnung zueinander besonders gut erkennbar.
Die aus Brettern bestehenden Einzelelemente 9 für die einzelnen Schichten können bezüglich ihres Querschnittes gleich, oder wie insbesondere in Figur 5 erkennbar, auch unterschiedlich ausgebildet sein.
Stirnseitig ist die Holzbautafel umlaufend mit einem Nut- und Federsystem versehen, wobei jeweils benachbarte Stirnseiten eine Nutausbildung 10 und die anderen beiden Stirnseiten eine Federausbildung 11 aufweisen. Dies ist gut in den Figuren 1 bis 3 erkennbar. Umlaufend sowohl bei der Nutausbildung 10 als auch bei der Federausbildung 11 sind in Faserlängsrichtung auskragende Einzelelemente 9 vorhanden, über die zu koppelnde Kräfte eingeleitet und übertragen werden können.
Durch das Ineinandergreifen benachbarter Holzbautafeln 1 (vgl. auch Fig. 6 und 7) wird eine hohe Verbindungsstabilität erreicht und außerdem ist keine durchgehende Fuge, die sonst zu Kältebrücken führen könnte, vorhanden.
In den Figuren 4 sowie 6 bis 10 ist auch erkennbar, daß die Randausbildung an den Stirnseiten der Holzbautafel in Abweichung z. B. zu Fig. 1 bis 3, variierte werden kann. Wesentlich ist hierbei nur, daß ein verzahnendes, überlappendes Ineinandergreifen der Einzelschichten von benachbart angeordneten Holzbautafeln 1 vorhanden ist. Wie bereits vorerwähnt, trägt dies wesentlich mit zu einem definiert vorgebbaren Wärme- und Schallschutzverhalten bei.
The middle layer 5 and the two adjacent intermediate layers 4 and 6 are also formed in parallel with respect to their individual elements 9, but here the individual elements run transversely to those of the outer double layers. This cross structure ensures a high level of stability, which means a two-dimensional, crosswise transfer of forces Enables both normal and bending forces. This also results in a high disk stiffness. This also prevents twisting of the wooden building panels and shrinking in length and width.
5, the individual layers 2 to 8 and their association with one another can be seen particularly well.
The individual elements 9 made of boards for the individual layers can have the same cross-section or, as can be seen in particular in FIG. 5, also be designed differently.
On the face side, the wooden building board is provided all round with a tongue and groove system, adjacent face ends each having a groove formation 10 and the other two end faces having a tongue formation 11. This can be clearly seen in FIGS. 1 to 3. All around, both in the groove formation 10 and in the tongue formation 11, individual elements 9 projecting in the longitudinal direction of the fibers are present, via which forces to be coupled can be introduced and transmitted.
The interlocking of adjacent wooden building panels 1 (cf. also FIGS. 6 and 7) achieves a high degree of connection stability and, moreover, there is no continuous joint which could otherwise lead to cold bridges.
In Figures 4 and 6 to 10 can also be seen that the edge formation on the end faces of the wooden construction board in deviation z. B. to Fig. 1 to 3, can be varied. It is only important that there is a toothed, overlapping interlocking of the individual layers of adjacent wooden building panels 1. As already mentioned, this contributes significantly to a predeterminable heat and sound insulation behavior.

Die Verbindung benachbarter Holzbautafeln 1 im Nut- und Federbereich kann durch Leimung und/oder Nägel, Schrauben oder dergleichen erfolgen. Die Leimverbindung sorgt außer zur Kraftübertragung auch für eine Dichtigkeit im Anschlußbereich. Bei kombinierter Anwendung von Leim und z. B. Nägeln ergibt sich praktisch eine Preßleimverbindung mit besonders guter Belastbarkeit.The connection of adjacent wooden building panels 1 in the tongue and groove area can be done by gluing and / or nails, screws or the like. The glue connection also provides Power transmission also for tightness in the connection area. When using glue and z. B. nails results in a press glue connection with particularly good resilience.

Bei den einzelnen Schichten sind durch die jeweils beabstandeten Einzelelemente 9 in Längsrichtung oder in Querrichtung durchgehende Kanäle 12 (vgl. Fig. 1 bis 3) gebildet, in denen Installationsleitungen oder Installationsrohre verlegt werden können. Auch ist dadurch die Möglichkeit gegeben, selbst nach dem Fertigstellen einer Gebäudewand und einer gegebenenfalls auf die aus Holzbautafeln 1 bestehende Wand aufgebrachten Beplankung (z. B. Gipskartonplatten), noch Zusatzinstallationen vorzunehmen.
Die vorhandenen Kanäle bilden insgesamt Hohlkammern, durch die eine ganz wesentliche Gewichtseinsparung und auch Materialeinsparung vorhanden ist. Trotzdem ist noch soviel Masse vorhanden, daß gegenüber einer üblichen Ständerbauweise eine wesentlich verbesserte Schalldämmung sowie Wärmespeicherkapazität vorhanden ist.
Durch die gegenseitige, kleinflächige, bzw. kleinstrukturierte Abstützung der Einzelelemente 9 gegeneinander, wird auch ein "Hohlraumeffekt" vermieden, da keine größerflächigen, schwingfähigen Plattenabschnitte vorhanden sind.
Auch ist dadurch das Befestigen von Regalen, Hängeschränken und dergleichen an solchen Wänden an jeder beliebigen Stelle problemlos möglich.
In the individual layers, through the respectively spaced-apart individual elements 9, continuous channels 12 (see FIGS. 1 to 3) are formed in the longitudinal direction or in the transverse direction, in which installation lines or installation pipes can be laid. This also makes it possible to carry out additional installations even after the completion of a building wall and a planking (for example plasterboard), which may have been applied to the wall consisting of wooden building boards 1.
The existing channels form a total of hollow chambers, through which a very substantial weight and material saving is available. Nevertheless, there is still so much mass that a significantly improved sound insulation and heat storage capacity is available compared to a conventional stand construction.
The mutual, small-area or small-structured support of the individual elements 9 against one another also avoids a “cavity effect” since there are no large-area, oscillatable plate sections.
This also enables the attachment of shelves, wall cabinets and the like to such walls at any desired location without any problems.

Die Herstellung der Holzbautafeln 1 erfolgt durch eine industrielle Serienfertigung, die eine hohe Maßgenauigkeit, vorgebbare Festigkeitswerte sowie eine kurze Herstellungszeit ermöglicht.
Die Einzelelemente 9 der Schichten 2 bis 8 werden bevorzugt durch Preßleimung miteinander verbunden, wodurch sich eine hohe Festigkeit ergibt.
The wooden building panels 1 are manufactured by industrial series production, which enables high dimensional accuracy, predeterminable strength values and a short manufacturing time.
The individual elements 9 of the layers 2 to 8 are preferably connected to one another by press gluing, which results in high strength.

Als Material können vergleichsweise kleinformatige Bretter verwendet werden, die beispielsweise eine Breite von 12 cm und eine Dicke von 2,4 cm haben können. Da die Holzbautafeln in handhabbaren Größen und in Anpassung an das vorhandene Mauerwerksraster dimensioniert sind, können sogenannte Kürzungsbretter, die bis zu 3 m lang sein können, verwendet werden. Dadurch ist in besonders vorteilhafter Weise eine Restholzverwertung möglich, die die Materialkosten ganz erheblich reduziert. Der Qualitätsanspruch der Hölzer beschränkt sich dabei auf die Festigkeit, wobei kein optischer Anspruch erforderlich ist.
In Fig. 11 sind in einem Bauwerksabschnitt erkennbar, welche Dimensionen die einzelnen Holzbautafeln 1 haben können. Es ist hieraus auch gut ersichtlich, daß praktisch ein Baukastensysstem vorhanden ist, welches die Montage bzw. das Erstellen von Wänden und Decken ganz erheblich vereinfacht. Außerdem können die Montagekosten durch einen vergleichsweise geringen Zeitaufwand reduziert werden.
Die einzelnen Holzbautafeln 1 können in unterschiedlichen Rastergrößen, wie dies in Fig. 11 gezeigt ist, vorgefertigt werden, so daß sie auch für die unterschiedlichsten Grundrisse und Ausführungen des Bauwerkes passen.
Bei Eckausbildungen und Übergängen zu anderen Bauteilen können unterschiedliche Endprofilstäbe 13 (Fig. 11 sowie Fig.8 bis 10) vorgesehen sein. Solche als Anschlußstücke dienenden Endprofilstäbe 13 sind in den Figuren 8 bis 10 in unterschiedlichen Ausführungsformen gezeigt.
Comparatively small-sized boards can be used as the material, which for example can have a width of 12 cm and a thickness of 2.4 cm. Since the wooden building boards are dimensioned in manageable sizes and in adaptation to the existing masonry grid, so-called shortening boards, which can be up to 3 m long, can be used. As a result, residual wood recycling is possible in a particularly advantageous manner, which considerably reduces the material costs. The quality standards of the woods are limited to the strength, with no visual requirements being required.
11 shows in a building section which dimensions the individual wooden building panels 1 can have. It can also be clearly seen from this that there is practically a modular system which considerably simplifies the assembly or the creation of walls and ceilings. In addition, the assembly costs can be reduced by a comparatively short expenditure of time.
The individual wooden building panels 1 can be prefabricated in different grid sizes, as shown in FIG. 11, so that they also fit for the most varied of layouts and designs of the building.
In the case of corner configurations and transitions to other components, different end profile bars 13 (FIGS. 11 and 8 to 10) can be provided. Such end profile rods 13 serving as connecting pieces are shown in FIGS. 8 to 10 in different embodiments.

Die erfindungsgemäße Holzbautafel läßt sich nicht nur als tragende Konstruktionwand einsetzen, sondern auch als Trennwand, wie dies beispielsweise in Figur 12 gezeigt ist. Zur Montagevereinfachung ist diese Holzbautafel 1a aus zwei Einzelverbundplatten 14, 15 zusammengesetzt, wobei sich hier die Trennebene 16 mittig dazwischen befindet.The wooden construction board according to the invention can be used not only as a load-bearing construction wall, but also as a partition, as is shown, for example, in FIG. To simplify assembly, this wooden construction panel 1a is composed of two individual composite panels 14, 15, with the parting plane 16 being located in the middle in between.

Die Einzelverbundplatten 14, 15 sind in dem gezeigten Ausführungsbeispiel aus jeweils drei kreuzweise zueinander angeordneten Schichten 17 bis 19 gebildet.
Vor der Montage lassen sich diese "halben" Holzbautafeln gut transportieren und handhaben. Der besondere Vorteil liegt aber darin, daß sie sich besonders gut auch zum nachträglichen Einbau von Trennwänden eignen.
Wie in Figur 12 erkennbar, sind am Boden 20 und an der Decke 21, gegebenenfalls auch an den Seitenwänden, Schwellen 22 vorgesehen, an die von beiden Seiten her die Einzelverbundplatten 14, 15 angesetzt und befestigt werden können. Die Art der Befestigung richtet sich hierbei nach der vorgesehenen Belastung der Holzbautafel. Gegebenenfalls können auch die einander zugewandten Flachseiten der Einzelverbundplatten 14,15 miteinander verbunden werden. Außer Schraubverbindungen kommen hier gegebenenfalls auch in Kombination Klebverbindungen in Frage, so daß nach der Montage der Einzelverbundplatten zu einer Holzbautafel eine hohe Stabilität erzielt werden kann.
Zumindest an den unteren und oberen Stirnrändern 23 sind Anschlußprofilierungen zum verdeckten Anbringen an den Schwellen 22 vorgesehen. Dazu weisen die jeweils inneren Schichten 17 einen Rücksprung gegenüber den anderen Schichten 18 und 19 etwa um die Höhe der Schwellen 22 auf. Die Gestaltung dieser Anschlußprofilierung kann entsprechend den jeweiligen Gegebenheiten variiert werden.
Durch die zweiteilige Ausbildung der Holzbautafel 1a und auch durch die vorgesehene Anschlußprofilierung ist eine praktisch verdeckte Befestigung der Holzbautafel ohne von außen sichtbare Befestigungsrahmen oder dergleichen möglich.
In the exemplary embodiment shown, the individual composite panels 14, 15 are each formed from three layers 17 to 19 arranged crosswise to one another.
These "half" wooden building panels can be easily transported and handled before assembly. The particular advantage, however, is that they are particularly well suited for retrofitting partitions.
As can be seen in FIG. 12, sleepers 22 are provided on the floor 20 and on the ceiling 21, optionally also on the side walls, to which the individual composite panels 14, 15 can be attached and fastened from both sides. The type of attachment depends on the intended load on the wooden panel. If necessary, the mutually facing flat sides of the individual composite panels 14, 15 can also be connected to one another. In addition to screw connections, adhesive connections may also be used here in combination, so that high stability can be achieved after assembly of the individual composite panels to form a wooden construction panel.
At least on the lower and upper end edges 23, connection profiles are provided for concealed attachment to the sleepers 22. For this purpose, the respective inner layers 17 have a recess relative to the other layers 18 and 19 by approximately the height of the sleepers 22. The design of this connection profile can be varied according to the respective circumstances.
Due to the two-part design of the wooden building board 1a and also due to the connection profile provided, a practically concealed fastening of the wooden building board is possible without fastening frames or the like which are visible from the outside.

Die Figuren 13 und 14 zeigen Holzbautafeln, die entweder einstückig oder für eine Zwischenwandmontage auch aus zwei Einzelverbundplatten 14, 15 ausgebildet sein können. Die Holzbautafel 1b gemäß Figur 13 weist acht Schichten auf, während die Holzbautafel 1c gemäß Figur 14 sechs Schichten hat. Zur Verwendung als Trennwand, wie anhand Figur 12 beschrieben, könnten die Holzbautafeln 1b und 1c in einer Trennebene 16 auch getrennt zweiteilig ausgebildet sein. Erwähnt sei in diesem Zusammenhang, daß es nicht unbedingt erforderlich ist, die Trennebene 16 in die Mittelebene der Holzbautafel zu legen. Bei einer zum Beispiel siebenschichtigen Holzbautafel besteht ebenfalls die Möglichkeit, diese in zwei Einzelverbundplatten aufzuteilen, wobei eine der Einzelverbundplatten dann aus drei Schichten und die andere aus vier Schichten besteht.
In Abwandlung zu den in Figur 1 bis 5 gezeigten Ausführungsbeispielen einer Holzbautafel 1 sind die Holzbautafeln 1b und 1c hinsichtlich ihrer Außenschichten geändert ausgebildet.
Bei der Holzbautafel 1b weisen die Einzelelemente 9 der Außenschichten 24 keinen oder nur einen geringen Abstand zueinander auf, so daß man praktisch vollflächig durchgehende Außenseiten erhält. Um Rißbildungen zu vermeiden, sind bevorzugt im Stoßbereich der Einzelelemente 9 der Außenschichten 24 geringfügige Abstände von zum Beispiel 1 bis 2 mm vorgesehen. Die Abdichtung der Außenschicht 24 erfolgt durch die nächste, darunter befindliche Schicht mit in gleicher Richtung orientierten und im Stoßbereich der äußeren Einzelelemente 9 angeordneten Einzelelementen.
Wie in Figur 14 gezeigt, besteht aber auch die Möglichkeit, zur Abdichtung anstatt zwei Schichten wie in Figur 13 nur eine Schicht 24a aus Nut- und Federbrettern vorzusehen. Durch das Ineinandergreifen dieser Einzelelemente ergibt sich eine genügende Abdichtung, so daß jeweils eine darunter befindliche Zwischenschicht vermieden werden kann. Je nach Anforderungen hinsichtlich Dichtigkeit, Dicke und/oder Stabilität kann entweder die Holzbautafel 1b oder 1c vorgesehen sein.
Bei der Holzbautafel 1c ist strichliniert noch eine benachbarte, weitere Holzbautafel 1c eingezeichnet. Hier ist deutlich zu erkennen, wie die Anschlußprofilierungen nut- und federartig ineinandergreifen.
FIGS. 13 and 14 show wooden building boards, which can either be made in one piece or, for an intermediate wall installation, from two individual composite panels 14, 15. The wooden construction board 1b according to FIG. 13 has eight layers, while the wooden construction panel 1c according to FIG. 14 has six layers. For use as a dividing wall, as described with reference to FIG. 12, the wooden building panels 1b and 1c could also be formed in two parts in a dividing plane 16. It should be mentioned in this connection that it is not absolutely necessary to place the parting plane 16 in the central plane of the wooden building board. In the case of a seven-layer wooden building panel, for example, there is also the possibility of dividing it into two individual composite panels, one of the individual composite panels then consisting of three layers and the other of four layers.
In a modification of the exemplary embodiments of a wooden building board 1 shown in FIGS. 1 to 5, the wooden building boards 1b and 1c are of different design with regard to their outer layers.
In the wooden construction panel 1b, the individual elements 9 of the outer layers 24 have no or only a small spacing from one another, so that outer sides which are practically full-surface are obtained. In order to avoid cracks, small distances of, for example, 1 to 2 mm are preferably provided in the joint area of the individual elements 9 of the outer layers 24. The outer layer 24 is sealed by the next layer below, with individual elements oriented in the same direction and arranged in the joint area of the outer individual elements 9.
As shown in FIG. 14, it is also possible to provide only one layer 24a of tongue and groove boards for sealing instead of two layers as in FIG. The interlocking of these individual elements results in a sufficient seal, so that an intermediate layer located underneath can be avoided in each case. Depending on the requirements with regard to tightness, thickness and / or stability, either the wooden building board 1b or 1c can be provided.
In the case of the wooden building board 1c, an adjacent, further wooden building board 1c is also shown in broken lines. Here is clearly recognizable how the connection profiles interlock like tongue and groove.

Figur 15 zeigt den Vertikalstoßbereich zwischen zwei aneinandergesetzten Holzbautafeln 1b mit abgewandelten Anschlußprofilierungen. Die Außenschichten 24 sind in diesem Ausführungsbeispiel gegenüber den inneren schichten etwas zurückversetzt und der Stoßbereich 25 wird dann durch äußere Bretter 26 abgedeckt, die zwischen die randseitig zurückversetzten Einzelelemente 9 der Außenschichten 24 eingesetzt sind.FIG. 15 shows the vertical joint area between two wooden building panels 1b placed against one another with modified connection profiles. In this exemplary embodiment, the outer layers 24 are set back somewhat from the inner layers, and the joint region 25 is then covered by outer boards 26 which are inserted between the individual elements 9 of the outer layers 24 set back on the edge.

Figur 16 zeigt den Anschlußbereich zweier rechtwinklig aufeinander stoßender Holzbautafeln 1 und Figur 17 die Ausbildung im Eckbereich zweier Holzbautafeln 1. Die in Figur 16 und 17 jeweils verwendeten Holzbautafeln 1 weisen gleiche Dicken und auch eine gleiche Anzahl von schichten auf.FIG. 16 shows the connection area of two wooden building panels 1 abutting at right angles and FIG. 17 shows the design in the corner area of two wooden building boards 1. The wooden building boards 1 used in FIGS. 16 and 17 each have the same thicknesses and the same number of layers.

Figur 18 zeigt den Anschlußbereich zwischen einer siebenschichtigen Holzbautafel und einer fünfschichtigen, beispielsweise als Trennwand dienenden weiteren Holzbautafel.
Figur 19 und 20 zeigen schließlich den Anschluß beziehungsweise Eckbereich von fünfschichtigen Holzbautafeln.
FIG. 18 shows the connection area between a seven-layer wooden building board and a five-layer further wooden building board, for example serving as a partition.
Figures 19 and 20 finally show the connection or corner area of five-layer wooden building panels.

Als Material für die Einzelelemente 9 wird vorgetrocknetes Holz verwendet, so daß auch dadurch eine Schwindfreiheit in Länge und Breite und damit präzise Abmessungen der fertigen Holzbautafel 1 vorhanden sind. Nach dem Verleimen der einzelnen Schichten wird die Holzbautafel zur Erzielung präziser Abmessungen auf Maß geschnitten und ringsherum umfräst, wobei diese Umfräsung so vorgenommen wird, daß im Nut- und Federsystem evtl. vorhandene Leimreste entfernt werden und gleichzeitig wird auch eine Anfasung der äußeren Kanten vorgenommen, damit das Zusammenstecken benachbarter Holzbautafeln problemlos und schnell möglich ist.Pre-dried wood is used as the material for the individual elements 9, so that there is also a shrinkage in length and width and thus precise dimensions of the finished wooden building board 1. After the individual layers have been glued, the wooden building board is cut to size and milled all around, this milling being carried out in such a way that any glue residues in the tongue and groove system are removed and at the same time chamfering of the outer edges is carried out, so that it is easy and quick to put together adjacent wooden building panels.

Erwähnt sei noch, daß durch die präzise Vorfertigung der Holzbautafeln 1 Wandunebenheiten praktisch ausgeschlossen sind, so daß auf eine Unterkonstruktion (Lattenrost) für eine aufzubringende Beplankung sowohl auf der Gebäudeinnenseite als auch auf der Außenseite verzichtet werden kann.It should also be mentioned that due to the precise prefabrication of the wooden building panels 1 wall unevenness is practically excluded, so that a substructure (slatted frame) can be dispensed with for planking to be applied both on the inside of the building and on the outside.

Kurz zusammengefasst ergeben sich bei der erfindungsgemäßen Holzbautafel 1 bzw. damit hergestellten Wänden, Decken oder Bedachungen folgende Hauptvorteile:
Materialeinsparung bei gleichbleibender Stabilität und gleichbleibendem Wärmeschutz;
Restholzverwertung und damit eine besonders preiswerte Herstellung möglich;
industrielle Serienfertigung im vorgegebenen Rasterformat;
geringe Abbund- und Montagekosten;
präzise Abmessungen;
Winddichtigkeit und atmungsaktiv;
problemlose Verlegung von Installationsleitungen und auch nachträgliche Installationsänderungsmöglichkeit;
Insgesamt sind somit durch die erfindungsgemäße Ausbildung der Holzbautafel 1 eine Vielzahl von Vorteilen in einem einzigen Bauteil vereint.
Es sei noch darauf hingewiesen, daß Variationen bezüglich der Dimensionierung der Einzelelemente 9 sowie der Anzahl und Anordnung der Schichten der Holzbautafel möglich sind. Dies kann in Anpassung an die jeweiligen Festigkeits- und/oder Isolationseigenschaften und dergleichen der Holzbautafel vorgenommen werden.
In brief, the following main advantages result in the wooden construction board 1 according to the invention and the walls, ceilings or roofs produced therewith:
Material savings with constant stability and constant heat protection;
Waste wood recycling and thus a particularly inexpensive production possible;
industrial series production in the specified grid format;
low joinery and assembly costs;
precise dimensions;
Windproof and breathable;
problem-free laying of installation lines and also the possibility of subsequent installation changes;
Overall, the inventive construction of the wooden panel 1 thus combines a large number of advantages in a single component.
It should also be pointed out that variations in the dimensions of the individual elements 9 and the number and arrangement of the layers of the wooden building board are possible. This can be done in adaptation to the respective strength and / or insulation properties and the like of the wooden building board.
