Die vorliegende Erfindung betrifft ein Holztragelement nach dem Oberbegriff von Anspruch 1.The present invention relates to a wooden support member according to the preamble of claim 1.

Solche Holztragelemente sind z.B. aus FR-A-2279900 oder FR-A-1158911 bekannt.Such wooden support elements are e.g. from FR-A-2279900 or FR-A-1158911.

Für das Erstellen von Bauten wird neben anderen Materialien häufig auch Holz eingesetzt. Dabei sind eine Vielzahl von verschiedenen Konstruktionsmöglichkeiten mit Holz bekannt; beispielsweise werden Holzbalken, -bretter oder -latten verwendet, welche miteinander form- und/oder kraftschlüssig verbunden werden, um die Bauten zu erstellen.For the construction of buildings, wood is often used in addition to other materials. There are a variety of different design options with wood known; For example, wooden beams, boards or slats are used, which are positively and / or non-positively connected with each other to create the buildings.

Insbesondere sind auch flächige Tragelemente bekannt, welche modulartig für den Aufbau von grösseren Objekten eingesetzt werden. Herkömmlicherweise sind derartige flächige Tragelemente mehrschichtig aus Balken und/oder Brettern aufgebaut.In particular, flat support elements are known which are used in a modular manner for the construction of larger objects. Conventionally, such flat support elements are constructed of multilayer beams and / or boards.

Wenn solche Tragelemente grössere Dimensionen aufweisen, insbesondere im Querschnitt, so wird der mehrschichtige Aufbau nicht in Vollbauweise mit einem kompakten, ausgefüllten Querschnitt ausgeführt, sondern es werden teilweise hohle Querschnitte gebildet. Diese Querschnittsräume sind herkömmlicherweise in der Regel relativ klein und häufig nicht über die volle Tragelementlänge durchgehend ausgebildet.If such support elements have larger dimensions, in particular in cross section, the multilayer construction is not carried out in full construction with a compact, filled cross section, but it is partially hollow cross sections are formed. These cross-sectional spaces are conventionally usually relatively small and often not continuously formed over the full length of support element.

Die Aufgabe der vorliegenden Erfindung bestand nun darin, ein solches flächiges Tragelement aus Holz zu schaffen, welches einerseits die erforderlichen Festigkeit und Steifigkeit aufweist, daneben aber innerhalb des Tragelementes resp. der durch derartige Tragelemente geschaffenen Struktur Raum für Installationen sowohl in Längs- wie in Querrichtung schafft.The object of the present invention was to provide such a flat support element made of wood, which on the one hand has the required strength and rigidity, but next within the support element, respectively. the structure created by such support members creates space for both longitudinal and transverse installations.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmal von Anspruch 1 gelöst.

Dabei weist beispielsweise eine Seite des Tragelementes eine ebene, durch die Platte gebildete Oberfläche auf, während die gegenüberliegende Seite durch die Verstärkungselemente eine Strukturierung aufweist.The inventive structure a timber component is created which has a very good, adjustable strength in light construction. In this case, for example, one side of the support element on a flat surface formed by the plate, while the opposite side has a structuring by the reinforcing elements.

Diese Strukturierung erlaubt bei der Verwendung als Wand, Boden, Decke oder Dach für ein Gebäude ein vorteilhaftes Ein- resp. Anbringen von Installationsmaterial zwischen dieser strukturierten Seite und einer davon beabstandet anzubringenden Schalung. Weiter kann darin auch eine Isolation angebracht werden. Vorteilhafterweise kann diese Seite aber auch als ästhetisches Element beim Errichten von Bauwerken eingesetzt werden, resp. die Verstärkungselemente können auch beidseitig des Bauelementes angebracht sein.This structuring allows when used as a wall, floor, ceiling or roof for a building an advantageous resp. Attaching installation material between this structured side and a spaced therefrom to be attached formwork. Furthermore, an insulation can also be installed therein. Advantageously, this page can also be used as an aesthetic element in the construction of buildings, resp. the reinforcing elements can also be attached on both sides of the component.

Der trapez- oder dreieckförmige Querschnitt des Hohlraumes der Verstärkungselemente lässt sich besonders einfach durch Leisten realisieren. Insbesondere die dreieckige Querschnittsfläche kann einfach durch entsprechende Anordnung von zwei Leisten erzielt werden.The trapezoidal or triangular cross section of the cavity of the reinforcing elements can be realized particularly easily by strips. In particular, the triangular cross-sectional area can be easily achieved by appropriate arrangement of two strips.

Durch die erfindungsgemäß angebrachten Ausnehmungen an den Verstärkungselementen wird der Zugang zum Hohlraum zur Nutzung für Installationen erheblich erleichtert. Dabei können jegliche Art von Installationen beispielsweise auch in diesen Hohlräumen verlegt werden, wie elektrische oder sanitäre Installationen.The inventively mounted recesses on the reinforcing elements access to the cavity for use for installations is greatly facilitated.

Durch die bevorzugte parallele Anordnung der Verstärkungselemente lassen sich modular einsetzbare Tragelemente herstellen, welche definierte Festigkeitseigenschaften aufweisen und die Dimensionierung für daraus zu bildenden Bauwerke einfach durchzuführen ist.The preferred parallel arrangement of the reinforcing elements makes it possible to produce modularly usable supporting elements which have defined strength properties and the dimensioning for structures to be formed from them can be carried out easily.

Insbesondere lassen sich derartige Module einfach und kostengünstig in Serie herstellen, was zu einer Reduktion der Kosten für die Erstellung der Bauwerke führt.In particular, such modules can be easily and inexpensively produced in series, which leads to a reduction in the cost of creating the structures.

Erfindungsgemäss eignen sich die erfindungsgemässen Tragelemente für das Errichten von geraden oder gekrümmten Wandelementen.

Figur 1 zeigt die Ansicht eines erfindungsgemässen Tragelementes 1 mit der hier aus verleimten Massivholzbrettern aufgebauter Platte 2 und dem aus zwei Leisten 3,4 aufgebauten Verstärkungselement 5. Wie die Platte 2 sind hier auch die Leisten 3,4 beispielsweise aus miteinander verleimten Massivholzplanken gebildet.FIG. 1 shows the view of a support element 1 according to the invention with the plate 2 constructed of solid wood boards and the reinforcing element 5 constructed of two strips 3. Like the plate 2, the strips 3, 4 are formed from solid wood planks glued together, for example.

Die Platte 2 weist vorzugsweise an einer Kante eine Feder 6 und auf der gegenüberliegenden Kante eine Nut 7 auf. Damit lassen sich mehrere solcher Tragelemente 1 miteinander auf einfache und sichere Weise in bekannter Weise verbinden. Selbstverständlich könnten auch an der oberen und unteren Kante der Platte 2 derartige Verbindungselemente vorgesehen sein, so dass mehrere Tragelemente 1 auch in Tragelementlängsrichtung miteinander verbunden werden können.The plate 2 preferably has a spring 6 on one edge and a groove 7 on the opposite edge. Thus, several such support elements 1 can be connected together in a simple and secure manner in a known manner. Of course, could also be at the top and bottom Edge of the plate 2 may be provided such fasteners, so that a plurality of support members 1 can be connected to each other in Tragelementlängsrichtung.

Durch die beiden Leisten 3 und 4 wird auf einfache Weise der vorzugsweise dreieckige Querschnitt des vorzugsweise vorgesehenen Hohlraumes 8 gebildet, wie auch aus der Querschnittsdarstellung von Figur 2 hervorgeht. Dieser Hohlraum 8 ist vorteilhaft durchgehend ausgebildet.By the two strips 3 and 4, the preferably triangular cross-section of the preferably provided cavity 8 is formed in a simple manner, as can be seen from the cross-sectional view of Figure 2. This cavity 8 is advantageously formed continuously.

Die Verbindung der Platte 2 mit den Leisten 3 und 4, sowie die Verbindung der beiden Leisten 3 und 4 kann auf alle herkömmlich bekannten Arten erfolgen. Beispielsweise eignet sich hierfür die Verleimung mit oder ohne Aufrauhung oder Profilierung der Verbindungsflächen oder die Verwendung von zusätzlichen Verbindungselementen wie Dübel, Nägel oder Schrauben.The compound of the plate 2 with the strips 3 and 4, as well as the connection of the two strips 3 and 4 can be done in all conventionally known ways. For example, this is the gluing with or without roughening or profiling of the bonding surfaces or the use of additional fasteners such as dowels, nails or screws.

Vorteilhafterweise können für den Aufbau der Platte 2, wie auch für die Leisten 3 und 4, Holzplanken resp. -latten unterschiedlicher Breite und Stärke eingesetzt werden.Advantageously, for the construction of the plate 2, as well as for the strips 3 and 4, wood planks resp. slats of different width and thickness are used.

In Figur 3 ist nun die Teilansicht eines weiteren erfindungsgemäss aufgebauten Tragelementes 1 dargestellt. Hier wird die Platte 2 durch quer zu den Verstärkungselementen 5 angeordneten und miteinander verleimten Planken gebildet. Ebenfalls sind mehrere, zueinander parallel angeordnete und vorzugsweise einen regelmässigen Abstand aufweisende Verstärkungselemente 5 vorhanden. Diese weisen nun erfindungsgemäß eine Vielzahl von hier kreisförmig ausgestalteten Ausnehmungen 9 auf. Damit wird das Durchführen von Installationseinrichtungen durch den Hohlraum 8 resp. den Ausnehmungen 9 sowie zwischen benachbarten Verstärkungselementen 5 vereinfacht. Die Anzahl, Grösse und Form dieser Ausnehmungen 9 kann entsprechend dem Einsatz der Tragelemente 1 angepasst ausgeführt werden.FIG. 3 shows the partial view of a further support element 1 designed according to the invention. Here, the plate 2 is formed by transverse to the reinforcing elements 5 arranged and glued together planks. Also, a plurality of mutually parallel and preferably a regular spacing having reinforcing elements 5 are present. According to the invention, these have a multiplicity of recesses 9 of circular design here. This is the implementation of installation equipment through the cavity 8, respectively. the recesses 9 and between adjacent reinforcing elements 5 simplified. The number, size and shape of these recesses 9 can be correspondingly be performed adapted to the use of the support elements 1.

Eine weitere Ausführungsvariante eines erfindungsgemässen Tragelementes 1 ist in Figur 4 in der Ansicht dargestellt. Wiederum sind mehrere, zueinander parallel verlaufende Verstärkungselemente 5 auf der Platte 2 angeordnet. Diese bilden hier wiederum im Querschnitt dreieckige Hohlräume 8. Im Bereich eines der Hohlräume 8' ist nun eine parallel zu den Verstärkungselementen 5 verlaufende Nut 10 in der Platte 2 vorgesehen. Diese Nut dient dem Ausgleich des Wachsens und Schwindens der Platte 2, wenn diese an ihren Enden fest verankert wird.A further embodiment variant of a support element 1 according to the invention is shown in FIG. 4 in the view. Again, a plurality of mutually parallel reinforcing elements 5 are arranged on the plate 2. In turn, these form triangular cavities 8 in cross-section. In the region of one of the cavities 8 ', a groove 10 running parallel to the reinforcing elements 5 is now provided in the plate 2. This groove serves to compensate for the growth and shrinkage of the plate 2, when it is firmly anchored at their ends.

Die erfindungsgemässen Tragelemente 1 können in der Grösse und der Anzahl sowie Positionierung der Verstärkungselemente 5 individuell dimensioniert werden, eignen sich aber vorteilhaft auch für den Aufbau von vorbestimmten Modulen mit festen oder abgestuften Dimensionen.The inventive support elements 1 can be individually dimensioned in size and the number and positioning of the reinforcing elements 5, but are also advantageous for the construction of predetermined modules with fixed or stepped dimensions.

Ebenfalls eignen sich schmale erfindungsgemässe Tragelemente 1 insbesondere zum Erstellen von gebogenen Wänden 11, wie in Figur 5 dargestellt. Hierfür sind lediglich beispielsweise die in Figur 1 dargestellten Feder 6 und Nut 7 entsprechend dem Wandradius R in einem Winkel zur Platte 2 anzufertigen. Selbstverständlich können auch andere, herkömmlichen Holzverbindungen eingesetzt werden. Die bevorzugte Ausgestaltung der Verstärkungselemente 5 mit Bildung eines dreieckigen Querschnitts der Hohlräume 8 erlaubt sehr einfach die Bildung von gebogenen Wänden 11 mit kleinem Radius R ohne grossen Aufwand.Also, narrow inventive support elements 1 are particularly suitable for creating curved walls 11, as shown in Figure 5. For this purpose, for example, only the spring 6 and groove 7 shown in Figure 1 according to the wall radius R at an angle to the plate 2 to make. Of course, other conventional wood joints can be used. The preferred embodiment of the reinforcing elements 5 with the formation of a triangular cross section of the cavities 8 very easily allows the formation of curved walls 11 with a small radius R without much effort.

Ein vorzugsweise trapezförmiger Querschnitt des Hohlraums 8 kann beispielsweise durch die Verwendung von drei Leisten 3,4 und 12, wie in Figur 6 dargestellt, einfach realisiert werden. Diese Querschnittsform weist im Gegensatz zur dreieckigen Querschnittsform ein grösseres nutzbares Volumen für die Aufnahme beispielsweise von Installationseinrichtungen bei gleicher Tiefe des Tragelementes 1 auf.A preferably trapezoidal cross-section of the cavity 8, for example, by the use of three strips 3,4 and 12, as shown in Figure 6, easily realized become. This cross-sectional shape, in contrast to the triangular cross-sectional shape on a larger usable volume for receiving, for example, installation equipment at the same depth of the support element 1.

In Figur 7 ist nun noch eine alternative Ausführungsform eines Tragelementes 1 mit einen trapezförmigen Querschnitt aufweisenden Verstärkungselementen 5 ohne Hohlraum 8 dargestellt. Beispielsweise können derartige Tragelemente 1 durch einen in diese Form gepressten resp. extrudierten Holzfaserwerkstoff gebildet werden.FIG. 7 shows an alternative embodiment of a support element 1 with reinforcement elements 5 having a trapezoidal cross-section without a cavity 8. For example, such support elements 1 by a pressed in this form resp. extruded wood fiber material are formed.

In Figur 8 ist nochmals eine weitere alternative Ausführung eines Tragelementes 1 dargestellt. Hier sind auf beiden Seiten der Platte 2 Verstärkungselemente 5 resp. 5' angeordnet. Beispielsweise sind die Verstärkungselemente 5 resp. 5' einander genau gegenüberliegend angeordnet, sie könnten aber auch gegeneinander versetzt angeordnet ausgebildet sein.FIG. 8 once again shows a further alternative embodiment of a support element 1. Here are on both sides of the plate 2 reinforcing elements 5 respectively. 5 'arranged. For example, the reinforcing elements 5 respectively. 5 'arranged opposite each other exactly, but they could also be arranged offset from each other.

In Figur 9 ist nun noch der Querschnitt durch ein Tragelemente 1 dargestellt, bei welchen die beiden äusseren Flanken 5' der beiden äussersten Verstärkungselemente 5 senkrecht zur Platte 2 stehend ausgebildet sind und auch gleichzeitig die seitliche Begrenzung des Tragelementes 1 darstellen. In den Flanken 5' sind auf einer Seite vorteilhaft eine Feder 13 und auf der anderen Seite eine Nut 14 ausgebildet, welche parallel zur Platte 2 verlaufend angeordnet sind.In Figure 9, the cross section is now shown by a supporting elements 1, in which the two outer edges 5 'of the two outermost reinforcing elements 5 are perpendicular to the plate 2 standing and also represent the lateral boundary of the support member 1. In the flanks 5 'are on one side advantageously a spring 13 and formed on the other side a groove 14 which are arranged to extend parallel to the plate 2.

In Figur 10 ist ein analog zur Figur 9 aufgebautes Tragelement 1 dargestellt, welches weniger Verstärkungselemente 5 bei gleichem Abstand aufweist und damit auch eine geringere Gesamtbreite. Solche Tragelemente 1 lassen sich auf einfache Weise zu ganzen Wänden, Böden oder Decken zusammenfügen. Bei Wandkonstruktionen können beispielsweise die Eckbereiche mit entsprechend ausgebildeten Pfosten, welche ebenfalls Nuten und Federn aufweisen, gebildet werden. Diese Pfosten können beispielsweise aus Vollmaterial bestehen oder ebenfalls aus einzelnen Planken zu einem beispielsweise einen quadratischen Querschnitt aufweisenden Hohlkörper aufgebaut sein.FIG. 10 shows a support element 1 constructed analogously to FIG. 9, which has fewer reinforcing elements 5 at the same spacing and thus also a smaller overall width. Such support elements 1 can be combined in a simple manner to form whole walls, floors or ceilings. In wall constructions, for example, the corner areas with correspondingly shaped posts, which also have grooves and springs, are formed. These posts may for example consist of solid material or also be constructed of individual planks to a, for example, a square cross section having hollow body.

Die Tragelemente 1 lassen sich praktisch aus allen beliebigen Holzwerkstoffen aufbauen, wie beispielweise aus Massivholz, aus verleimten Holzplanken, aus mehrschichtigen Holzplatten, aus Spanplatten oder Holzfaserwerkstoffen.The support elements 1 can be practically built from any wood materials, such as solid wood, glued wood planks, multi-layer wood panels, chipboard or wood fiber materials.
