Description
Beschreibung [0001] Gegenstand der Erfindung ist ein vorgefertigtes Bauelement aus Holz gemäss Oberbegriff des Patentanspruchs 1.Description: The invention relates to a prefabricated structural element made of wood according to the preamble of patent claim 1.
[0002] Bei der Erstellung von Bauten, insbesondere Bauten für Schulen, Restaurants oder öffentliche Räume stellt die Akustik ein grosses Problem dar. Insbesondere, wenn die Böden in solchen Gebäuden eine glatte Oberfläche aufweisen, wie beispielsweise Steinplatten oder Holzdielen.In the construction of buildings, especially buildings for schools, restaurants or public spaces, acoustics is a major problem. In particular, when the floors in such buildings have a smooth surface, such as stone slabs or wood flooring.
Aus dem Stand der Technik sind verschiedene Produkte zur Dämmung des Schalls bekannt. Einerseits können unter bestehende Decken Schallschutzplatten aus faserigen Materialien gehängt werden, die meist eine raue Oberfläche aufweisen. Ebenfalls bekannt sind Deckenplatten aus Holz, welche aus parallel nebeneinander liegenden Brettern bestehen, zwischen denen schalldämmende Elemente eingesetzt sind. Eine solche Holzdecke ist aus der DE 10 2014 000 686 A1 bekannt. Bei dieser sogenannten Dübelholzdecke sind die hochkantstehenden Bretter mit seitlichen Nuten versehen, in die die schallschluckenden Elemente eingesetzt sind. Oberhalb der schallschluckenden Elemente liegen die Seitenwangen der Bretter satt aufeinander und werden durch Dübel zusammengehalten. Unterhalb der schallschluckenden Elemente sind die Bretter schmaler ausgebildet, so dass ein von unten offener Schlitz erzeugt wird. Unterhalb der schallschluckenden Elemente ist zudem ein Fliess eingelegt, welches verhindert, dass Fasern aus dem schallschluckenden Element durch den Schlitz nach unten fallen können.Various products for the insulation of the sound are known from the prior art. On the one hand, sound insulation panels made of fibrous materials can be hung under existing ceilings, which usually have a rough surface. Also known are ceiling panels made of wood, which consist of parallel side by side boards, between which sound-absorbing elements are used. Such a wooden ceiling is known from DE 10 2014 000 686 A1. In this so-called dowel wood ceiling, the upright boards are provided with lateral grooves, in which the sound-absorbing elements are used. Above the sound-absorbing elements, the side cheeks of the boards are full of each other and are held together by dowels. Below the sound-absorbing elements, the boards are narrower, so that a slot open from below is produced. Below the sound-absorbing elements, a flow is also inserted, which prevents fibers from the sound-absorbing element from falling down through the slot.
Eine ähnliche Konstruktion, welche als Holzdeckenelement oder als Holzwandelement konzipiert ist, ist aus der EP 2 196 592 B1 bekannt. Bei diesem Element sind analog zur oben bezeichneten Ausführung Holzbretter nebeneinander angeordnet und durch Holzdübel miteinander verbunden. Auch bei dieser Holzdecke sind in seitlichen Nuten an den Brettern Schallschutzelemente eingelegt. Schlitze in den Brettern ermöglichen den Eintritt des Schalls von unten in die Schallschutzelemente, wo der Schall schlussendlich absorbiert wird.A similar construction, which is designed as a wooden ceiling element or as a wooden wall element, is known from EP 2 196 592 B1. In this element, wood boards are arranged side by side analogous to the above-mentioned embodiment and connected by wooden dowels. Even with this wooden ceiling sound insulation elements are inserted in lateral grooves on the boards. Slots in the boards allow the sound to enter from below into the soundproofing elements, where the sound is ultimately absorbed.
In einer weiteren Ausgestaltung eines Holzfertigbauelements gemäss EP 2 080 845 B1 sind zwischen rechteckförmigen Brettern schalldämmende Elemente eingelegt, die sich entweder über die gesamte Höhe der Bretter erstrecken oder nur über einen Teilbereich. In einer Ausführungsform sind einzelne Bretter bezüglich der benachbarten nach oben verschoben und überragen die Oberkanten der benachbarten Bretter und Schalldämmelemente. Unterhalb der jeweils nach oben verschobenen Bretter ergibt sich dadurch eine Nut, die seitlich von Schallschutzelemente gebildet wird. Dadurch sollen die in die Nuten eindringenden Schallwellen gedämmt werden.In a further embodiment of a wood prefabricated element according to EP 2 080 845 B1, sound insulating elements are inserted between rectangular boards, which extend either over the entire height of the boards or only over a partial area. In one embodiment, individual boards are shifted upwardly with respect to the adjacent ones and project beyond the upper edges of the adjacent boards and sound insulation elements. Below the respective upwardly shifted boards, this results in a groove formed laterally by soundproofing elements. This is intended to dampen the sound waves entering the grooves.
Eine befriedigende Lösung des Akustikproblems wird nicht offenbart.A satisfactory solution of the acoustic problem is not revealed.
[0003] Eine Aufgabe der vorliegenden Erfindung ist die Schaffung eines vorgefertigten Bauelements mit einem möglichst hohen Schallabsorptionsgrad. Eine weitere Aufgabe ist die Schaffung eines Bauelements, mit dem zugleich eine tragende Decke erstellt werden kann, d.h. das Bauelement soll nicht nur optimale Schallabsorptionseigenschaften aufweisen, sondern sich direkt als Decke oder tragendes Element für ein darüber liegendes Stockwerk geeignet sein. Eine weitere Aufga.be ist die Schaffung eines Bauelements, das einerseits optimale Schallabsorptionseigenschaften aufweist und andererseits als verlorene Schalung mit statischen Eigenschaften für eine darüber zu erstellende Betondecke geeignet ist.An object of the present invention is to provide a prefabricated device with the highest possible degree of sound absorption. A further object is to provide a component with which a load-bearing ceiling can be created at the same time, ie. The device should not only have optimal sound absorption properties, but be suitable directly as a ceiling or supporting element for a floor above. Another Aufga.be is the creation of a device that on the one hand has optimal sound absorption properties and on the other hand is suitable as a permanent formwork with static properties for a concrete ceiling to create about it.
[0004] Gelöst wird diese Aufgabe durch ein vorgefertigtes Bauelement gemäss den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen des Bauelements sind in den abhängigen Ansprüchen umschrieben.This object is achieved by a prefabricated component according to the features of claim 1. Advantageous embodiments of the device are described in the dependent claims.
[0005] Mit der erfindungsgemässen Anordnung lässt sich ein Akustik-Bauelement mit optimalen Schallschluck- bzw. Schallabsorptionswerten erreichen. Gleichzeitig verfügt das Bauelement über eine hohe Tragfestigkeit bei einer Verwendung direkt als Decke oder als verlorene Schalung für eine Holzbeton-Verbunddecke. Die gewünschte Schallabsorption lässt sich durch das Verhältnis der Breite der Bretter und der Breite der dazwischen liegenden schallabsorbierenden Platten an die jeweiligen Erfordernisse anpassen. Eine weitere Anpassungsmöglichkeit besteht durch die Wahl der Höhenausdehnung der Platten zwischen den Brettern.With the arrangement according to the invention, an acoustic component with optimal sound absorption or sound absorption values can be achieved. At the same time, the component has a high load-bearing capacity when used directly as a ceiling or as a permanent formwork for a wood-concrete composite ceiling. The desired sound absorption can be adapted to the respective requirements by the ratio of the width of the boards and the width of the sound-absorbing panels in between. Another adaptability is through the choice of the vertical extent of the plates between the boards.
Durch die geeignete Wahl der Breite und Höhe der Platten, welche die Absorption von Schallwellen übernehmen, lässt sich das Bauelement an die gegebenen gebäulichen Umstände anpassen. Durch einen zusätzlich zwischen zwei benachbarten Brettern unterhalb der dazwischen liegenden Platte angeordneten porösen Körper, lassen sich weitere Vorteile erzeugen, nämlich von den aus losen Fasern bestehenden Platten durch allfällige Erschütterungen sich ablösende Fasern werden zurückgehalten und können nicht in den Raum gelangen und andererseits kann bereits durch den porösen Körper ein Teil der Schallwellen absorbiert werden. Ein dazwischen liegender Raum verhindert die direkte Übertragung von Schwingungen des porösen Körpers, sofern solche auftreten, an die untere Stirnfläche der Platte.By appropriate choice of the width and height of the plates, which take over the absorption of sound waves, the device can be adapted to the given circling circumstances. By additionally arranged between two adjacent boards below the plate lying therebetween porous body, further advantages can be produced, namely of the loose fibers existing plates by any shocks peeling fibers are retained and can not get into the room and on the other hand can already by Part of the sound waves are absorbed by the porous body. An intervening space prevents the direct transmission of vibrations of the porous body, if any, to the lower face of the plate.
[0006] Anhand illustrierter Ausführungsbeispiele wird die Erfindung näher erläutert. Es zeigen:Based on illustrated embodiments, the invention will be explained in more detail. Show it:
Fig. 1 einen Vertikalschnitt durch ein schmales Bauelement mit drei Brettern; Platte beabstandet zum porösen Abschlusskörper,1 shows a vertical section through a narrow component with three boards. Plate spaced from the porous end body,
Fig. 2 einen Vertikalschnitt durch ein Bauelement mit Platten zwischen den Brettern mit gleicher Breite wie die Bretter und Platten, die auf dem Abschlusskörper aufliegen,2 shows a vertical section through a component with plates between the boards with the same width as the boards and plates, which rest on the closing body,
Fig. 3 einen Vertikalschnitt durch ein weiteres Bauelement, bei dem die Verhältnisse der Höhe zur Breite wesentlich grösser ist als in den Fig. 1 und 2,3 shows a vertical section through a further component in which the ratios of the height to the width is substantially greater than in FIGS. 1 and 2,
