Definitions
- the invention relates to a building element according to the preamble of claim 1.
- Building elements are used to construct buildings, and are basic components of, for example, walls, ceilings, floors or roofs. Building elements are either transported in a prefabricated state from a production site to a construction site, or manufactured directly at the site of, or in the vicinity of, the site and then assembled into a building. Prefabricated building elements are usually referred to as "prefabricated parts” and buildings constructed from these as “precast constructions". The construction of buildings from building elements differs from conventional construction methods for buildings mainly in that the construction time of the building, for example, compared to brick structures, greatly reduced. Furthermore, prefabricated building elements according to the current state of the art are usually produced partially or fully automatically, whereby a further reduction of the construction costs and the construction time, or the production time of the building elements, can be achieved.
- the document AT 13952 U1 discloses a wall element of juxtaposed solid wood rods which extend over the entire height of the wall element.
- the solid wood rods have Lekssfräsungen on, with the individual solid wood rods interlock by means of longitudinal milling.
- Such building elements according to the prior art have the disadvantage that their production requires a large amount of high-quality solid wood.
- Another disadvantage is that high quality solid wood is available on the market only to a limited extent and at high prices, which increases the cost of building elements according to the prior art.
- Another disadvantage is that the use of solid solid wood elements results in constraining the design freedom for the building elements produced in this way. For example, a wall thickness of one using the in AT 13952 U1 wall produced wall element shown a multiple of a diameter of the solid wood rods, even if such a wall thickness is not necessary in a specific use case. This also results in an increased consumption of resources in anyway expensive and poorly available high-quality solid wood.
- the object is achieved by a building element having the features of claim 1.
- the embodiment of the building element according to the invention provides a core layer which comprises at least two core layer layers.
- the core layer layers extend substantially over an element length, each core layer layer having an inner surface and an outer surface opposite the inner surface.

It is particularly advantageous that in this way, for example, plywood, or even softwood or other inexpensive and readily available wood elements can be used as core layer layers.
- the cross-connection elements can also be made of wood, whereby a building element according to the invention is produced, which consists exclusively of wood.
- Another advantage is that is dispensed with in the production of the building element on additional connecting means such as glue, glue, or screw. As a result, the environmental impact of the building element is further increased.
- the building element is suitable for use in regions in which modern fasteners, tools and construction machines are not or only to a limited extent available.
- the modular structure of the core layer allows an adaptation of the device to the requirements of different locations. For example, the requirement for increased mechanical stability or thermal insulation can be easily met by adding additional core layer layers without increasing the complexity of the design.

Description
Die Erfindung betrifft ein Gebäudeelement gemäß dem Oberbegriff von Anspruch 1.The invention relates to a building element according to the preamble of
Gebäudeelemente werden zur Errichtung von Gebäuden verwendet, und stellen Grundbestandteile von beispielsweise Wänden, Decken, Böden oder Dächern dar. Gebäudeelemente werden entweder in einem vorgefertigten Zustand von einer Produktionsstätte zu einer Baustelle transportiert, oder direkt am Ort der Baustelle, oder in deren Nähe, hergestellt und anschließend zu einem Gebäude zusammengefügt. Vorgefertigte Gebäudeelemente werden in der Regel als "Fertigteile" und aus diesen errichtete Gebäude als "Fertigteilkonstruktionen" bezeichnet. Die Herstellung von Gebäuden aus Gebäudeelementen unterscheidet sich von herkömmlichen Errichtungsverfahren für Gebäude im Wesentlichen dadurch, dass die Errichtungszeit des Gebäudes beispielsweise im Vergleich zu Ziegelkonstruktionen, stark reduziert wird. Des Weiteren werden vorgefertigte Gebäudeelemente nach dem aktuellen Stand der Technik in der Regel teil- oder vollautomatisiert hergestellt, wodurch eine weitere Reduktion der Errichtungskosten und der Errichtungszeit, beziehungsweise der Herstellungszeit der Gebäudeelemente, erreicht werden kann.Building elements are used to construct buildings, and are basic components of, for example, walls, ceilings, floors or roofs. Building elements are either transported in a prefabricated state from a production site to a construction site, or manufactured directly at the site of, or in the vicinity of, the site and then assembled into a building. Prefabricated building elements are usually referred to as "prefabricated parts" and buildings constructed from these as "precast constructions". The construction of buildings from building elements differs from conventional construction methods for buildings mainly in that the construction time of the building, for example, compared to brick structures, greatly reduced. Furthermore, prefabricated building elements according to the current state of the art are usually produced partially or fully automatically, whereby a further reduction of the construction costs and the construction time, or the production time of the building elements, can be achieved.
Ein weiterer wichtiger Aspekt der Bautechnik liegt in der Nachhaltigkeit und der Umweltverträglichkeit der verwendeten Baumaterialien. Aus diesem Grund besteht in letzter Zeit ein erhöhter Bedarf an aus Holz gefertigte Gebäudeteilen. Herkömmlicherweise werden für moderne Holzkonstruktionen Bauteile aus Brettschichtholz verwendet, welche aus mehreren vorverleimten Holzschichten bestehen. Es sind auch Systeme am Markt verfügbar, welche es erlauben Holzbauteile ohne die Verwendung von Leim oder Metallverbindern wie Bolzen oder Schrauben zu fertigen. Diese weisen eine besonders hohe Umweltverträglichkeit und Nachhaltigkeit auf.Another important aspect of construction technology is the sustainability and environmental compatibility of the building materials used. For this reason, there has recently been an increased demand for wooden building parts. Conventionally, for modern wooden structures components made of glued laminated timber are used, which consist of several pre-glued layers of wood. Systems are also available on the market which allow wood components to be manufactured without the use of glue or metal connectors such as bolts or screws. These have a particularly high environmental impact and sustainability.

Derartige Gebäudeelemente gemäß dem Stand der Technik weisen den Nachteil auf, dass deren Herstellung eine große Menge an qualitativ hochwertigem Vollholz erfordert. Ein weiterer Nachteil besteht darin, dass hochqualitatives Vollholz am Markt nur in eingeschränktem Umfang und zu hohen Preisen zur Verfügung steht, wodurch die Kosten der Gebäudeelemente gemäß dem Stand der Technik erhöht werden. Ein weiterer Nachteil besteht darin, dass die Verwendung von massiven Vollholzelementen dazu führt, dass der Gestaltungsspielraum für die auf diese Weise hergestellte Gebäudeelemente eingeschränkt wird.

Die erfindungsgemäße Ausführung des Gebäudeelements sieht eine Kernschicht vor, welche zumindest zwei Kemschichtlagen umfasst. Die Kemschichtlagen erstrecken sich im Wesentlichen über eine Elementlänge, wobei jede Kernschichtlage eine Innenfläche und eine der Innenfläche gegenüberliegende Außenfläche aufweist. Die Innenfläche und die Außenfläche weisen jeweils eine Quernut auf. Die Quernut kann in die Innenfläche beziehungsweise die Außenfläche beispielsweise eingefräst sein. Die Quernuten verlaufen in einer Querrichtung entlang des Gebäudeelements, welche im Wesentlichen normal auf die Elementlänge orientiert ist. In der Quernut einer Innenfläche und in der Quernut einer an diese Innenfläche angrenzenden Außenfläche ist des Weiteren ein Querverbindungselement angeordnet. Das Querverbindungselement verbindet die beiden Kernschichtlagen zu der Kernschicht. Hierdurch wird der Vorteil erreicht, dass ein Gebäudeelement eine Kernschicht aufweist, welche aus mehreren Kernschichtlagen gefertigt ist, wobei die einzelnen Kernschichtlagen keine erhöhten Anforderungen hinsichtlich Belastbarkeit oder struktureller Stabilität zu erfüllen haben. Besonders vorteilhaft ist, dass hierdurch beispielsweise Sperrholz, oder sogar Weichholz beziehungsweise sonstige kostengünstige und leicht verfügbare Holzelemente als Kernschichtlagen eingesetzt werden können. Die Querverbindungselemente können des Weiteren ebenfalls aus Holz gefertigt sein, wodurch ein erfindungsgemäßes Gebäudeelement erzeugt wird, welches ausschließlich aus Holz besteht. Ein weiterer Vorteil besteht darin, dass bei der Herstellung des Gebäudeelements auf zusätzliche Verbindungsmittel wie beispielsweise Leim, Klebstoff, oder Schraubverbindungen verzichtet wird. Hierdurch wird die Umweltverträglichkeit des Gebäudeelements weiter gesteigert. Des Weiteren eignet sich das Gebäudeelement zum Einsatz in Regionen, in welchen moderne Verbindungsmittel, Werkzeuge und Baumaschinen nicht oder nur in eingeschränktem Umfang zur Verfügung stehen. Besonders vorteilhaft ist, dass der modulare Aufbau der Kernschicht eine Adaption des Bauelements an die Anforderungen unterschiedlicher Standorte ermöglicht. Beispielsweise kann die Anforderung nach einer erhöhten mechanischen Stabilität oder Wärmedämmung durch das Hinzufügen zusätzlicher Kernschichtlagen auf einfache Weise erfüllt werden, ohne die Komplexität der Konstruktion zu erhöhen.The embodiment of the building element according to the invention provides a core layer which comprises at least two core layer layers.

The transverse grooves extend in a transverse direction along the building element, which is oriented substantially normal to the element length. Furthermore, a transverse connecting element is arranged in the transverse groove of an inner surface and in the transverse groove of an outer surface adjoining this inner surface. The cross-connection element connects the two core layer layers to the core layer. In this way, the advantage is achieved that a building element has a core layer, which is made of several core layer layers, wherein the individual core layer layers do not have to meet increased requirements in terms of resilience or structural stability.

Gemäß der bevorzugten Ausführungsform des erfindungsgemäßen Gebäudeelements 1 weist das Querverbindungselement 7 eine Länge auf, welche im Wesentlichen einer halben Ausdehnung eines der Kemschichtsegmente 9 in der Querrichtung Q des Gebäudeelements 1 entspricht. Hierdurch wird der Vorteil erreicht, dass die Querverbindungselemente 7 die Stöße der Kernschichtsegmente in der Querrichtung Q überlappen und somit erhöhte Stabilität erreicht wird. Des Weiteren können mehrere Kernschichtsegmente 9 angrenzender Kernschichtlagen 3 versetzt zueinander angeordnet und mit einem Querverbindungselement 7 verbunden werden. Hierdurch wird der Vorteil erreicht, dass die Kemschichtsegmente 9 verschiedener Kernschichtlagen 3 mechanisch belastbar verbunden werden und die Kernschicht 2 eine erhöhte mechanische Stabilität aufweist.According to the preferred embodiment of the
Besonders vorteilhaft ist, das Querverbindungselement 7 in den Quernuten 6 von zwei in der Querrichtung Q aufeinanderfolgend angeordneten Kemschichtsegmenten 9 anzuordnen. Hierdurch wird der Vorteil erreicht, dass die mechanische Stabilität der Kernschicht 2 weiter erhöht wird.It is particularly advantageous to arrange the transverse connecting
Gemäß der bevorzugten Ausführungsform der Erfindung weist das erfindungsgemäße Gebäudeelement 1 zumindest eine durch die Kernschicht 2 verlaufende Kernschichtnut 10 auf. Die Kernschichtnut 10 ist an einer Position eines Stoßes aufeinanderfolgender Kemschichtsegmente 9 ausgebildet. Die Kernschichtnut 10 umfasst zwei Hälften, wobei jeweils eine Hälfte in einem von den zwei aufeinanderfolgenden Kernschichtsegmenten 9 ausgebildet ist. Beim Zusammenfügen der aufeinanderfolgenden Kemschichtsegmente 9 zu einer Kernschichtlage 3 werden die beiden Hälften an dem Stoß zu einer vollständigen Kernschichtnut 10 zusammengefügt. Das erfindungsgemäße Gebäudeelement 1 umfasst zumindest ein in der Kernschichtnut 10 angeordnetes Kemverbindungselement 11. Das Kemverbindungselement 11 stellt in Verbindung mit der Kernschichtnut 10 eine mechanisch stabile Verbindung der aufeinanderfolgenden Kemschichtsegmente 9 bereit. Hierdurch wird der Vorteil erreicht, dass die Kernschichtsegmente 9 entlang der Querrichtung Q mechanisch stabil fixiert werden, und ein auseinanderdriften der aufeinanderfolgenden Kernschichtsegmente 9 unter Last verhindert wird. Der in
Besonders vorteilhaft ist, das Kemverbindungselement 11, wie in
Das Gebäudeelement 1 umfasst des Weiteren in der bevorzugten Ausführungsform eine Innenabdeckung 12, welche sich im Wesentlichen über die Elementlänge L erstreckt. Die Innenabdeckung 12 ist an einer von der Innenfläche 4 einer der Kernschichtlagen 3 gebildeten Seite der Kernschicht 2 angeordnet. Die Innenabdeckung 12 weist zumindest eine in der Querrichtung Q verlaufende Innennut 13 auf. Das Gebäudeelement 1 weist ein Halteelement 14 auf, welches an der an die Innenabdeckung 12 anschließenden Innenfläche 4 befestigt, und in der Innennut 13 angeordnet ist. Wie in
Das in
Des Weiteren umfasst die Außenabdeckung 15 in der bevorzugten Ausführungsform des Gebäudeelements 1 in der Querrichtung Q aufeinanderfolgend angeordnete Außensegmente 18. Hierdurch wird, analog wie bei der segmentierten Innenabdeckung 12, der Vorteil erreicht, dass die Außenabdeckung 15 nicht aus einem Stück gefertigt werden muss und somit kostengünstiger herzustellen ist. Des Weiteren ergeben sich ähnliche Vorteile in Bezug auf die Einfachheit des Zusammenbaus des erfindungsgemäßen Gebäudesegments 1, sowie hinsichtlich der optischen Gestaltungsmöglichkeiten.Furthermore, in the preferred embodiment of the
Wie in
Des Weiteren ist in dem Stoß der aufeinanderfolgenden Außensegmente 18 ein Stoßdichtelement 21 angeordnet. Das Stoßdichtelement 21 kann beispielsweise als Dichtschnur ausgebildet sein, welche in einer zwischen den aufeinanderfolgenden Außensegmenten 18 ausgebildeten Nut angeordnet ist. Die Dichtschnur kann unter Anderem aus Hanf bestehen und kann beispielsweise mit einem organischen Dichtmittel wie Teer oder Fett durchsetzt sein. Die Dichtschnur kann beispielsweise mittels einer auf dem Gebiet des Bootsbaus bekannten Technik unter Verwendung eines Hammers und eines Kalfateisens in den Stoß geschlagen werden. Hierdurch wird der Vorteil erreicht, dass der Stoß aufeinanderfolgender Außensegmente 18 zusätzlich abgedichtet wird. In dem in
Die Kernschichtlagen 3 mit den Kernschichtsegmenten 9, die Querverbindungselemente 7, und die Kemverbindungselemente 11 des erfindungsgemäßen Gebäudeelements 1 sind gemäß einer Ausführungsvariante vollständig aus Holz gefertigt. Das Gebäudeelement 1 ist dieser Ausführungsvariante ohne Innenabdeckung 12 und Außenabdeckung 15 ausgeführt und besteht ausschließlich aus Holz. Gemäß einer weiteren Ausführungsvariante besteht zumindest eines aus den Kemschichtsegmenten 9, den Querverbindungselementen 7, und den Kernverbindungselementen 11 aus Holz.The
Gemäß einer weiteren Ausführungsvariante besteht das Gebäudeelement 1 bis auf zumindest einem aus der Innenabdeckung 12, der Außenabdeckung 15, den Halteelementen 14 und den Außendichtelementen 19 aus Holz. Alternativ können die Außendichtelemente 19 ebenfalls auch Holz bestehen.According to a further embodiment, the
Des Weiteren kann das Stoßdichtelement 21 aus einem von Holz verschiedenen Material bestehen. Das Stoßdichtelement 21 kann beispielsweise wie zuvor beschrieben aus Hanf bestehen. Hierdurch wird der Vorteil erreicht, dass ein im Wesentlichen vollständig aus Holz gefertigtes Gebäudeelement 1 bereitgestellt wird, welches eine besonders hohe Umweltverträglichkeit aufweist und zu einer nachhaltigen Ressourcennutzung beiträgt.Furthermore, the
Es kann erwähnt werden, dass Kernschichtsegmente 9 um ein oder mehrere Kernschichtlagen 3 versetzt zueinander untereinander verbunden werden können, um eine Stufe oder Schräge in dem Gebäudeelement zu realisieren, wie dies in
