Description

Technisches Gebiet:Technical area:

Die Erfindung betrifft ein Holzdeckenelement oder Holzwandelement bestehend aus längs aneinander gefügten Holzbrettern, zwischen denen jeweils Isolierkörper angeordnet sind, wobei auf der Sichtseite des Elements zwischen benachbarten Holzbrettern längs verlaufende Fugen ausgebildet sind, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a wooden ceiling element or wooden wall element consisting of longitudinally joined wooden boards, between which each insulating body are arranged, being formed on the visible side of the element between adjacent wooden boards longitudinal joints, according to the preamble of claim 1.

Stand der Technik:State of the art:

Es sind Holzbrettsperrholzprodukte als tragende Bauelemente für Wände, Decken, Dächer und Fassaden sowie als nicht tragende Elemente beim Innenausbau bekannt. Diese Holzbrettsperrholzprodukte sind nach dem Holzbrettsperrholzprinzip aufgebaut, wobei Schichten aus Nadelholz kreuzweise verklebt werden, so dass Holzbrettlagen auf Abstand angeordnet sind. Dadurch können zwischen den aus einzelnen Holzbrettern aus Nadelholz bestehenden Schichten längs verlaufende Hohlräume für die Aufnahme von Installationen, Dämmungen oder Akustikabsorber gebildet werden, wobei die Hohlräume derart gestaltet sein können, dass auf der Sichtseite des Bauelements zwischen den Schichten Sichtfugen verbleiben. Die Herstellung derartiger Bauelemente ist allerdings aufwendig, da sämtliche Schichten kreuzweise verklebt werden müssen.There are wooden board plywood products known as load-bearing components for walls, ceilings, roofs and facades as well as non-structural elements in interior design. These wooden board plywood products are constructed according to the wood-block plywood principle, wherein layers of softwood are cross-glued, so that wooden board layers are arranged at a distance. As a result, longitudinally extending cavities for receiving installations, insulation or acoustic absorbers can be formed between the layers consisting of individual wooden boards made of softwood, wherein the cavities can be designed in such a way that visible joints remain on the visible side of the component between the layers. However, the production of such components is expensive, since all layers must be glued crosswise.

Durch die DE 201 07 152 U1 ist ein tragendes, raumhohes Holzwandelement mit auf Abstand verbundenen Wandteilen bekannt geworden, bei welchem Scharen von Längslatten mit quer zu diesen mit gegenseitigem Vertikalabstand angeordneten Querstegen verleimt sind und in den Hohlräumen zwischen den Längslatten und den Querstegen Dämmmaterial angeordnet ist. Die Scharen von Latten sind dergestalt angeordnet, dass zumindest auf einer Hauptoberfläche des Holzwandelements, nämlich die Sichtseite, Fugen zwischen den einzelnen Latten vorhanden sind. Die vertikalen, tragenden Längslatten einer Schar haben einen gegenseitigen Abstand, der größer gewählt ist als der Durchmesser eines Installationsrohres von Rohverrohrungen. Als Dämmmaterial sind in die Hohlräume Holzweichfasern, Flachs, Hanf oder Steinwolle eingebracht. Aufgrund seines hohen Gewichts ist dieses Wandelement jedoch nur als solches einzusetzen, wie es auch aufwändig in seinem Aufbau und damit in seiner Herstellung ist.By the DE 201 07 152 U1 is a load-bearing, room-high wooden wall element known with distance connected wall parts, in which flocks of longitudinal slats are glued with transverse to these arranged with mutual vertical spacing transverse webs and in the cavities between the longitudinal slats and the transverse webs insulating material is arranged. The flocks of slats are arranged such that, at least on a main surface of the wooden wall element, namely the visible side, joints between the individual slats are present. The vertical, supporting longitudinal slats of a crowd have a mutual distance, which is chosen larger than the diameter of an installation pipe of Rohleitrohrungen. As insulation material wood soft fibers, flax, hemp or rock wool are introduced into the cavities. Because of his high weight, however, this wall element is used only as such, as it is also complex in its construction and thus in its production.

Des Weiteren ist durch die DE 203 15 506 U1 eine vorgefertigte Baustruktur, insbesondere eine Holzdecke, mit einer Decklage, bevorzugt aus Holzmaterial und mehreren Balkenträgern, insbesondere aus Holz, bekannt geworden, wobei mehrere Durchführungen für Rohre, Kabel o. dgl. vorgesehen sind und wobei die Durchführungen quer zur Hauptrichtung der Balkenträger der Baustruktur im Bereich der neutralen Faser angeordnet sind.Furthermore, by the DE 203 15 506 U1 a prefabricated building structure, in particular a wooden ceiling, with a cover layer, preferably made of wood material and several beam supports, in particular made of wood, known, with several bushings for pipes, cables o. The like. Are provided and wherein the bushings transversely to the main direction of the beam support the building structure are arranged in the region of the neutral fiber.

Jedes einzelne Holzbrett 2 ist dergestalt geformt, dass es im Querschnitt auf zwei sich planparallel gegenüber liegenden Seiten je eine längs des Holzbretts 2 verlaufende Aussparung 6, 6' aufweist, welche zur längs verlaufenden Mittelebene 15 des Holzbretts oder der -lamelle sowie der beiden sich planparallel gegenüber liegenden Seiten symmetrisch sind, wobei das Holzbrett 2 im Querschnitt, im Wesentlichen, Doppel-T-förmig gestaltet ist, wie es aus Figur 1 hervorgeht. Durch die Aussparungen 6, 6' wird jeweils wenigstens eine seitliche, längs verlaufende Begrenzungsfläche ausgebildet. Bevorzugt sind durch jede der Aussparungen 6, 6' drei seitliche Begrenzungsflächen 8, 9, 10 ausgebildet, welche auf der gegenüberliegenden Seite des Holzbrettes 2 spiegelsymmetrisch zur Mittelebene 15 ebenfalls vorhanden sind. Ebenso sind die Begrenzungsflächen 7 und 11 eines oberen Querteils 4 und eines unteren Querteils 5 des Holzbretts 2 auf der gegenüberliegenden Seite des Holzbrettes 2 spiegelsymmetrisch zur Mittelebene 15 ebenfalls vorhanden. Bevorzugt verläuft die Begrenzungsfläche 9 der Aussparungen 6, 6' parallel zur Mittelebene 15, die Begrenzungsflächen 8 und 10 der Aussparungen 6, 6' verlaufen senkrecht zur Mittelebene 15, wie es der Figur 1 zu entnehmen ist. Normalerweise ist die Höhe h des Holzbrettes 2 größer als seine ursprüngliche Breite a. Die Aussparungen 6, 6' selbst können auch bombiert oder konkav ausgeführt sein.The FIG. 1 shows a cross section through five longitudinally joined wooden boards or slats 2, which form in their composite a wooden ceiling element 1 or a wooden wall element. Each individual wooden board 2 is shaped in such a way that it has in cross section on two sides parallel to one another along the wooden board 2 extending recess 6, 6 ', which to the longitudinal center plane 15 of the wooden board or the lamella and the two are plane-parallel opposite sides are symmetrical, wherein the wooden board 2 is designed in cross-section, essentially, double-T-shaped, as is made FIG. 1 evident. Through the recesses 6, 6 'in each case at least one lateral, longitudinal boundary surface is formed.
