Description

Die Erfindung betrifft eine CLT-Platte, bzw. CLT-Paneele.The invention relates to a CLT board or CLT panels.

CLT-Paneele ("Cross Laminated Timber", auf Deutsch: Brettsperrholz) sind vorgefertigte Holzbauelemente, die aus mehreren übereinanderliegenden Schichten von Massivholzplatten bestehen. Diese Schichten werden kreuzweise zueinander angeordnet und in der Regel durch Verleimen fest miteinander verbunden. Durch diese Kreuzverleimung entstehen großformatige, stabile und vielseitig einsetzbare Platten, die vor allem im Holzbau verwendet werden.CLT panels ("Cross Laminated Timber") are prefabricated timber construction elements consisting of several stacked layers of solid wood panels. These layers are arranged crosswise and are usually firmly bonded together by gluing. This cross-lamination creates large-format, stable, and versatile panels that are primarily used in timber construction.

CLT besteht in der Regel aus Nadelhölzern wie Fichte, Tanne oder Kiefer, die aufgrund ihrer Festigkeit und Verfügbarkeit bevorzugt werden.CLT is usually made of softwoods such as spruce, fir or pine, which are preferred due to their strength and availability.

CLT-Paneele können im Hochbau für Wände, Decken und Dächer verwendet. Sie bieten eine nachhaltige Alternative zu Beton und Stahl und eignen sich sowohl für Einfamilienhäuser als auch für mehrgeschossige Gebäude. CLT-Paneele zeichnen sich durch eine hohe Tragfähigkeit, gute Wärmedämmung und Brandschutzwerte aus. Zudem sind sie aufgrund ihrer Vorfertigung zeitsparend in der Montage und werden in der Regel auf Baustellen als passgenaue Elemente angeliefert.CLT panels can be used in building construction for walls, ceilings, and roofs. They offer a sustainable alternative to concrete and steel and are suitable for both single-family homes and multi-story buildings. CLT panels are characterized by high load-bearing capacity, good thermal insulation, and fire protection values. Furthermore, their prefabrication saves time during assembly and they are usually delivered to construction sites as custom-fit elements.

WO 2012/149634 A1 beschreibt ein CLT-Paneel mit CLT und einer dazwischen verklebten Isolierung. WO 2012/149634 A1 describes a CLT panel with CLT and insulation bonded between them.

Aus der WO 2012/149634 A1 ist ein Grundaufbau eines Paneels bekannt, das Holzplatten und Isolierungsschichten aufweist. Die Paneele sind miteinander steckbar.From the WO 2012/149634 A1 A basic panel structure is known, consisting of wooden panels and insulation layers. The panels can be plugged together.

WO 2020/146210 A1 zeigt ein CLT-Paneel mit einer Führung, die für die Durchführung von Kabeln, aber auch für die Integration von Wasserleitungen nutzbar ist. WO 2020/146210 A1 shows a CLT panel with a guide that can be used for the passage of cables, but also for the integration of water pipes.

WO 2013/1890498 A1 beschreibt ein CLT-Paneel mit Nuten, in denen Verstärkungselemente vorgesehen sind. WO 2013/1890498 A1 describes a CLT panel with grooves in which reinforcement elements are provided.

WO 2020/242809 A1 offenbart ein CLT-Paneel mit Kanälen, die mit Bindermaterial verfüllt werden. WO 2020/242809 A1 reveals a CLT panel with channels filled with binder material.

Problematisch bei den bekannten Paneelen ist, dass es zu Schimmelbildung kommen kann, wenn nicht eine ausreichende Durchlüftung sichergestellt wird und sich Kondenswasser ansammelt.The problem with the well-known panels is that mold can form if sufficient ventilation is not ensured and condensation accumulates.

Aufgabe der Erfindung ist es eine CLT-Platte und hieraus hergestellte CLT-Paneele bereitzustellen, die eine einfache und sichere Montage ermöglicht und die Bildung von Schimmelpilz verhindert.The object of the invention is to provide a CLT board and CLT panels made therefrom which enable simple and safe installation and prevent the formation of mould.

Gelöst wird die Aufgabe durch die Erfindung gemäß des Anspruchs 1. Bevorzugte Ausgestaltungen finden sich in den abhängigen Ansprüchen.The object is achieved by the invention according to claim 1. Preferred embodiments can be found in the dependent claims.

Eine CLT-Platte gemäß der Erfindung weist mehrere Rinnen oder Kanäle auf, die zumindest auf einer Seitenfläche der CLT-Platte vorliegen.A CLT panel according to the invention has a plurality of grooves or channels present on at least one side surface of the CLT panel.

Die CLT-Platte weist Rinnen oder Nuten auf, die beispielsweise eingefräst sein können. Die Rinnen können insbesondere auf der zu einer Isolierung gerichteten Seite der CLT-Platte vorhanden sein. Die Rinnen verlaufen vorzugsweise in etwa schräg und können in unterschiedlichen Winkeln angeordnet sein, beispielsweise 45°, 25° oder 10°, wobei der Winkel je nach einer Verwendung der CLP-Platte anpassbar ist. Vorteilhafterweise können mehrere Rinnen vorgesehen sein, die beispielsweise in einer Art Schachbrettmuster angeordbar sind.The CLT panel has channels or grooves, which can be milled, for example. The channels can be present, in particular, on the side of the CLT panel facing the insulation. The channels preferably run approximately diagonally and can be arranged at different angles, for example, 45°, 25°, or 10°, whereby the angle can be adjusted depending on the use of the CLT panel. Advantageously, several channels can be provided, which can be arranged, for example, in a kind of checkerboard pattern.

Zwischen den Rinnen kann ein Abstand von beispielsweise 10 cm vorliegen. Die Rinnen können halbrohrförmig gestaltet sein, d. h. im Wesentlichen parallele Seitenwände besitzen. Es kann jedoch auch vorgesehen sein, dass die Rinnen konisch verlaufen.The distance between the gutters can be, for example, 10 cm. The gutters can be semi-tubular, i.e., have essentially parallel side walls. However, the gutters can also be conical.

Die Rinnen können sich in einer Ausgestaltung kreuzen. Außerdem können im Wesentlichen horizontal verlaufende Rinnen vorgesehen sein, die auch mehrere schräg laufende Rinnen verbinden und/oder senkrechte Rinnen.The channels may intersect in one configuration. Furthermore, essentially horizontal channels may be provided that also connect several inclined channels and/or vertical channels.

Ferner betrifft die Erfindung eine CLT-Paneele, die mehrere CLT-Platten umfasst. Die CLT-Paneele kann mehrere CLT-Platten umfassen, wobei zwischen Paaren von den CLT-Platten je eine Dämm- oder Isolierschicht vorliegen kann. Die Dämm- oder Isolierschicht kann beispielsweise Holzfaser, Schafwolle, Hanfwolle oder ein sonstiges dem Fachmann bekanntes Dämmmaterial sein. Die Dämm- oder Isolierschicht kann zwischen zwei Platten verpresst sein.The invention further relates to a CLT panel comprising a plurality of CLT boards. The CLT panel may comprise a plurality of CLT boards, wherein an insulating layer may be present between each pair of CLT boards. The insulating layer may be, for example, wood fiber, sheep's wool, hemp wool, or another insulating material known to those skilled in the art. The insulating layer may be pressed between two boards.

Die CLT-Platten können auf die angedachte Verwendung passgenau zugeschnitten werden. Des Weiteren können zwischen zwei Platten in jeweils einer Dämm- oder Isolierschicht Abstandshalter oder Verbinder vorliegen, die beispielsweise als Leisten aus Konstruktionsvollholz vorliegen. Die Abstandshalter können vorzugsweise bei einer mehrschichtigen CLT-Paneele in den beiden Isolierschichten zueinander versetzt angeordnet sein, damit sie keine Kältebrücke bilden. In den Abstandshaltern können Löcher für Gewindestangen vorgesehen sein, über die die CLT-Paneele miteinander verbindbar sind. Außerdem können in einer Isolierschicht Löcher, Durchlässe, Kanäle oder dergleichen für Kabel etc. integriert sein.The CLT panels can be cut to size for their intended use. Furthermore, spacers or connectors, such as strips made of solid structural timber, can be placed between two panels in each insulation layer. Preferably, in a multi-layer CLT panel, the spacers can be offset from one another in the two insulation layers to prevent thermal bridges. Holes for threaded rods can be provided in the spacers, which can be used to connect the CLT panels to one another. Furthermore, holes, passages, channels, or the like for cables, etc., can be integrated into an insulation layer.

Die CLT-Paneele können über eine Nut-Feder-Verbindung miteinander verbindbar sein. Es kann jedoch auch vorgesehen sein, dass die CLT-Paneele endständig Nuten oder Aussparungen aufweisen, so dass in die Nuten zweier zu verbindender CLT-Paneele ein Verbindungsmittel einbringbar ist. Die Nuten zweier CLT-Paneele können einen Kanal bilden, der zwei sich gegenüberstehende Öffnungen aufweist. Das Verbindungsmittel, z. B. eine Leiste, ein Brett oder dergleichen kann aus Richtung einer der Öffnungen in den Kanal eingebracht werden und weist insbesondere die Größe des Kanals auf. Hierdurch können beide CLT-Paneele miteinander verbunden werden.The CLT panels can be connected to each other via a tongue and groove connection. However, it can also be provided that the CLT panels have grooves or recesses at their ends, so that the grooves of two A connecting element can be inserted between the CLT panels to be joined. The grooves of two CLT panels can form a channel with two opposing openings. The connecting element, e.g., a strip, a board, or the like, can be inserted into the channel from the direction of one of the openings and, in particular, has the same size as the channel. This allows both CLT panels to be connected to one another.

Die Herstellung von CLT-Panels ist nicht teuer, es entstehen keine CO2-Emissionen in die Atmosphäre und es sind nur minimale Investitionen in Produktionsausrüstung und Arbeitspersonal erforderlich. Der Transport der Paneele kann auf Europaletten erfolgen und mit kleinen oder großen Fahrzeugen transportiert werden. Der Bau von Häusern von ca. 150 m2 Wohnfläche aus CLT-Paneele kann von 1 bis 3 Personen in bis zu 5 Arbeitstagen aufgebaut werden.The production of CLT panels is inexpensive, produces no CO2 emissions into the atmosphere, and requires minimal investment in production equipment and labor. The panels can be transported on Euro pallets and transported by small or large vehicles. Houses with approximately 150 m² of living space made of CLT panels can be constructed by one to three people in up to five working days.

In den beigefügten Zeichnungen 1-13 wird die Erfindung beispielhaft illustriert.The invention is illustrated by way of example in the accompanying drawings 1-13.

Je nach Bedarf, können die CLT-Paneele mehrere Schichten umfassen, d. h. es können mehrere Isolierschichten 2 mit CLT-Platten 1 vorgesehen sein.The following are examples of the advantages of the invention: The CLT panels comprise CLT boards 1 and can be used as walls, ceilings, or floors of a house. Depending on requirements, the CLT panels can comprise multiple layers, i.e., multiple insulation layers 2 with CLT boards 1 can be provided.

Raumluft kann über entsprechend in einer CLT-Platte 1 vorgesehene Rinnen, Löcher, Kanäle 8 oder dergleichen in die CLT-Paneele diffundieren. Der in der Raumluft vorhandene Wasserdampf kondensiert in den CLT-Paneelen und wird über die Rinnen 8 verteilt. Das in den Rinnen 8 vorhandene Kondensat verdunstet wieder. Überflüssiges Kondensat kann abgeleitet werden. Das Wasser verdunstet gleichmäßig über die Rinnen 8 nach außen. Kondensat verteilt sich gleichmäßig über die Rinnen. Luft bleibt warm oder kalt.Room air can diffuse into the CLT panels via grooves, holes, channels 8, or the like provided in a CLT panel 1. The water vapor present in the room air condenses in the CLT panels and is distributed via the grooves 8. The condensate present in the grooves 8 evaporates again. Excess condensate can be drained away. The water evaporates evenly to the outside via the grooves 8. Condensate is distributed evenly across the grooves. The air remains warm or cold.

Horizontale Rinnen 9, die im Sinne der Erfindung auch als Kanäle bezeichnet werden können, verbinden die vertikalen Rinnen 8 miteinander, sodass das gesamte Kondenswasser gleichmäßig über die Fläche der Platten 1 durch die Rinnen 8 abfließt und nach außen verdunstet. Sofern die CLT-Paneele als Wand, Decke und/oder Boden verwendet werden, befindet sich das Haus in einem trockenen Zustand. Außerdem strömt durch diese Rinnen 8 oder Kanäle warme Luft aus dem Inneren der Räume, die beispielsweise durch menschliche Körpertemperatur entstanden ist, wodurch die Wände lange Zeit warm bleiben. Ferner dringt von außen kalte oder heiße Luft ein, wodurch die Luft für den Körper angenehm ist und die Lufttemperatur im Haus für das menschliche Leben normal bleibt. Hierdurch normalisieren die Wände mit Rinnen oder Kanälen sowohl im Sommer als auch im Winter die Temperatur im Haus. Kanäle 8 können unterschiedliche Breiten, Tiefen und unterschiedliche Grade haben, sie können auch kegelförmig, quadratisch oder rund sein, unterschiedliche Neigungen oder Grade haben, alles hängt von der Region ab. Ecken und Paneele haben die gleiche Funktion. Ein Haus aus solchen Paneelen muss praktisch nicht beheizt werden oder benötigt keine Klimaanlage.Horizontal gutters 9, which can also be referred to as channels within the meaning of the invention, connect the vertical gutters 8 to each other, so that all condensation flows evenly across the surface of the panels 1 through the gutters 8 and evaporates to the outside. If the CLT panels are used as walls, ceilings, and/or floors, the house is kept dry. Furthermore, warm air from the interior of the rooms, generated, for example, by human body temperature, flows through these gutters 8 or channels, keeping the walls warm for a long time. Furthermore, cold or hot air penetrates from outside, making the air comfortable for the body and maintaining a normal air temperature in the house for human life. Thus, walls with gutters or channels normalize the temperature in the house both in summer and winter. Channels 8 can have different widths, depths, and different angles; they can also be conical, square, or round, with different inclinations or angles, all depending on the region. Corners and panels serve the same function. A house made of such panels practically does not need to be heated or air-conditioned.

Häuser, die erfindungsgemäße CLT-Platten 1 oder CLT-Paneele umfassen, sind erdbebensicher, flutsicher und genügen den Brandschutzanforderungen. Die CLT-Paneele verziehen sich nicht mehr und können ohne Weiteres beschichtet werden, z. B. verputzt werden, mit Rigips beschichtet werden oder dergleichen.Houses comprising CLT boards 1 or CLT panels according to the invention are earthquake-proof, flood-proof, and meet fire protection requirements. The CLT panels no longer warp and can be easily coated, e.g., plastered, coated with drywall, or the like.

Des Weiteren kann über die Rinnen eine Trocknung oder Erwärmung eines Hauses erfolgen, indem beispielsweises (erwärmte) Luft in die Rinnen gepumpt wird.Furthermore, the gutters can be used to dry or heat a house, for example by pumping (heated) air into the gutters.

Die Kanäle, Rinnen, Fräsungen 8, dienen der Stabilisierung der Luft nach wissenschaftlichen Erkenntnissen der gebrochenen Luft, die durch die CLT-Platten 1 eindringt, sowie durch die Isolierung 2. Dadurch kommt es nicht auf die Temperatur außerhalb des Hauses an, sondern diese Kanäle gleichen die Temperatur aus und stabilisieren auch die gleiche Lufttemperatur in verschiedene Richtungen. Daher ist es vorteilhaft, wenn sich die Kanäle unabhängig von der Temperatur außerhalb des Hauses zwischen der Isolierung befinden und sich auf der Seite der Isolierung auf den CLT-Platten 1 befinden. Die Temperatur im Haus hängt von der Dicke der Paneele und davon ab, wie viele CLT-Platten 1 mit Kanälen, Fräsungen 8 zwischen der Isolierung 2 angebracht sind. Je mehr CLT-Platten 1 sich dort befinden, wo sich die Kanäle befinden, desto besser wird die Luft stabilisiert. Somit beträgt die Innenlufttemperatur im Haus ungefähr 20-23° Celsius, unabhängig von der Lufttemperatur außerhalb des Hauses. Darüber hinaus hängt die Lufttemperatur im Haus von der Anzahl der Fenster im Haus, ihrer Größe und Verglasung ab. Die Regelung der Lufttemperatur funktioniert insbesondere als Sandwich aus CLT-Platten 1 mit Isolierung. Je dicker das Sandwich, desto besser stabilisiert es die Luft im Haus so dass keine Notwendigkeit besteht, das Haus zu heizen oder klimatisieren.The channels, grooves, and millings (8) serve to stabilize the air according to scientific principles, based on the refracted air that penetrates through the CLT panels (1) and the insulation (2). This means that the temperature outside the house is not affected; instead, these channels equalize the temperature and also stabilize the same air temperature in different directions. Therefore, it is advantageous if the channels are located between the insulation, regardless of the temperature outside the house, and are located on the insulation side of the CLT panels (1). The temperature inside the house depends on the thickness of the panels and the number of CLT panels (1) with channels and millings (8) installed between the insulation (2). The more CLT panels (1) there are where the channels are located, the better the air is stabilized. Thus, the indoor air temperature in the house is approximately 20–23° Celsius, regardless of the air temperature outside. Furthermore, the air temperature inside the house depends on the number of windows in the house, their size, and glazing. The air temperature control works particularly well as a sandwich of CLT 1 panels with insulation. The thicker the sandwich, the better it stabilizes the air in the house, eliminating the need for heating or air conditioning.

Ein weiterer Vorteil CLT-Paneele besteht darin, dass die Paneele über Luftkanäle, Rinnen, Fräsungen 8 verfügen, was bedeutet, die Häuser aus solchen Paneelen sind für Regionen, in denen Erdbeben oder Überschwemmungen häufig vorkommen, sehr stabil errichtet, selbst wenn Wasser in das Haus eindringt. Gerade durch diese miteinander verbundenen Luftkanäle, Rinnen, Fräsungen werden die Wände des Hauses sehr schnell belüftet und trocknen dadurch aus. In einem Erdbebengebiet können die CLT-Paneele in vertikaler Position mit Stahl-Gewindestangen schrittweise zusammen verdreht, oder festverdreht sein.Another advantage of CLT panels is that the panels have air ducts, gutters, millings 8, which means that the houses made of Such panels are very stable in regions where earthquakes or floods are common, even if water penetrates the house. These interconnected air ducts, gutters, and grooves allow the walls of the house to be ventilated very quickly, thus drying out. In an earthquake zone, the CLT panels can be twisted together in a vertical position using steel threaded rods, or they can be tightly twisted.
