Abstract
Description
Die Erfindung bezieht sich auf ein Bauelement aus Mehrschichtholz mit zumindest drei kreuzweise miteinander verbundenen Lagen.The The invention relates to a component made of multi-ply wood at least three crosswise interconnected layers.
Es sind bereits Brettschichthölzer bekannt, die aus parallel aufeinander verleimten Brettern bestehen. Entsprechend den statischen Anforderungen wird der Gesamtquerschnitt als statisch tragende Einheit berechnet. Mit Brettschichthölzern lassen sich Tragfähigkeiten erreichen, die mit Vollholz nicht erreichbar sind. Darüber hinaus wird durch den mehrschichtigen Aufbau eine Rissbildung vermieden. Die Verformung dieser Brettschichthölzer quer zur Faser verhält sich jedoch wie Bauschnittholz, wobei Brettschichthölzer in Abhängigkeit von der Holzausgleichsfeuchte schwinden und quellen.It are already glulam timbers known, which consist of parallel glued boards. According to the static requirements, the total cross section calculated as a static unit. With laminated timber can be capacities reach, which are not accessible with solid wood. Furthermore The cracking is avoided by the multilayer structure. The deformation of these glulam sticks across the fiber behaves however, like building timber, with glulam depending on the timber moisture balance dwindle and swell.
Weiterhin kennt man sogenannte Brettsperrhölzer, die wie Brettschichtholz aus einzelnen Brettlagen bestehen, die jedoch nicht parallel sondern kreuzweise miteinander verleimt sind, so dass eine hohe Formstabilität erreicht wird. Die Querlagen beeinträchtigen jedoch die zulässige Biegebeanspruchung, weil sogenannter Rollschub die Tragfähigkeit des Gesamtquerschnitts beeinträchtigt. Durch den Rollschub werden die Schubverformungen der Querlage(n) bei Beanspruchung rechtwinklig zur Plattenebene bestimmt.Farther one knows so-called board plywood, which consist of single board layers like glued laminated timber, the but not parallel but glued together crosswise, allowing a high dimensional stability is reached. The transverse layers, however, impair the permissible bending stress, because so-called roller thrust the carrying capacity of the total cross-section impaired. By the shear thrust the shear deformations of the transverse position (s) determined at stress at right angles to the plate plane.
Hinzu kommt noch eine weitere Beeinträchtigung durch Kriechverformung.in addition there is another impairment by creep deformation.
Aufgabe der vorliegenden Erfindung ist es, ein Holzbauelement zu schaffen, das die Nachteile von Brettschichthölzern und Brettsperrhölzer vermeidet und deren Vorteile vereint.task the present invention is to provide a timber component, which avoids the disadvantages of glulam timber and board plywoods and their advantages united.
Zur Lösung dieser Aufgabe wird vorgeschlagen, dass eine zwischen zwei Längslagen befindliche Querlage beabstandet zueinander angeordnete Querlagenbretter aufweist und dass zwischen benachbarten Querlagenbrettern in Längslagenrichtung orientierte und mit den beiden Längslagen verbundene Zwischenbretter angeordnet sind.to solution This object is proposed that one between two longitudinal layers located transverse position spaced from each other transverse planks and that oriented between adjacent transverse layer boards in the longitudinal direction and with the two longitudinal layers interconnected intermediate boards are arranged.
Mit Hilfe der Zwischenbretter werden die auftretenden Schubkräfte über die Längslagen abgetragen und damit die Rollschubverformung bei den Querlagen eliminiert.With Help the intermediate boards are the thrust forces on the longitudinal layers removed and thus eliminates the roll shear deformation in the transverse layers.
Der Gesamtquerschnitt des erfindungsgemäßen Holzbauelements bleibt so formstabil wie Brettsperrholz. Es ist kein Schwinden und Quellen möglich und auch keine Volumenvergrößerung bei Feuchteaufnahme. Weiterhin tritt keine Rissbildung nach der Heizperiode im Winter durch Feuchteabgabe auf.Of the Overall cross-section of the timber component according to the invention remains As dimensionally stable as cross laminated timber. There is no shrinking and swelling possible and also no increase in volume with moisture absorption. Furthermore, no cracking occurs after the heating season in winter by moisturization on.
Nachteilige Auswirkungen von Rollschub werden vermieden, so dass bei der Berechnung im Biegebereich auch kein Rollschub berücksichtigt werden muss. Dementsprechend sind bei gleicher Festigkeit schlankere Querschnitte möglich, wodurch geringere Kosten entstehen. Außerdem ist keine Berücksichtigung des Abminderungsfaktors bei der Kriechverformung erforderlich. Bei der Betrachtung des Bauteils als Brettschichtholz fungieren die Querlagen auch als Querzugsicherung.Adverse Effects of roller thrust are avoided, so when calculating In the bending area also no roll thrust must be considered. Accordingly With the same strength, slimmer cross-sections are possible, resulting in smaller ones Costs arise. Furthermore is not considered the reduction factor required in the creep deformation. at the consideration of the component as glulam act the Transverse layers also as a cross-train protection.
Die Tragfähigkeit des erfindungsgemäßen Holzbauelements ist im Vergleich zu Brettsperrholz wesentlich erhöht.The Load capacity the timber component according to the invention is significantly increased compared to cross laminated timber.
Das Holzbauelements kann im Bereich der Querlage(n) jeweils zwischen benachbarten Querlagenbrettern wenigstens zwei Zwischenbretter aufweisen, wodurch bereits eine deutliche Stabilisierung vorhanden ist.The Wooden component can be in the area of the transverse position (s) between each adjacent cross-ply boards have at least two intermediate boards, which already provides a significant stabilization.
Es können aber auch auf die Länge der Querlagenbretter verteilt mehrere Zwischenbretter angeordnet sein, wobei die Anzahl und der Abstand der Zwischenbretter zueinander an die Festigkeitsanforderungen angepasst ist.It can but also on the length the transverse layer boards distributed several intermediate boards arranged be, with the number and spacing of the intermediate boards to each other adapted to the strength requirements.
Die Zwischenbretter können auch über die Länge der Querlagenbretter seitlich aneinander liegend angeordnet sein, so dass keine Zwischenräume zwischen den Zwischenbretter vorhanden sind und somit innerhalb des Holzbauelements keine Hohlräume.The Intermediate boards can also over the length the transverse layer boards are arranged side by side, so no gaps between the intermediate boards are present and thus within the timber component no cavities.
Eine optimierte Ausführungsform des Holzbauelements sieht vor, dass die Gesamtfläche der vorgesehenen Zwischenbretter einer Querlage für das Bauelement etwa fünfzig Prozent der Gesamtfläche des Bauelements entspricht.A optimized embodiment of the timber component provides that the total area of the proposed intermediate boards a transverse position for the Component about fifty Percent of the total area of the component corresponds.
Damit wird hinsichtlich der Festigkeit bereits ein Maximum erreicht.In order to In terms of strength is already reached a maximum.
Die einzelnen Lagen des Mehrschichtholz-Bauteils sind miteinander verleimt, um eine qualitativ hochwertige, belastbare Verbindung zu erreichen.The individual layers of the multilayer wood component are glued together, to achieve a high quality, resilient connection.
Nachstehend ist die Erfindung anhand der Zeichnungen näher beschrieben.below the invention is described in more detail with reference to the drawings.
