Description
Die vorliegende Erfindung betrifft ein schallabsorbierendes Bausystem, insbesondere mit Paneelen.The present invention relates to a sound-absorbing building system, in particular with panels.
In Gebäuden, insbesondere in Hallen, Büros, Freiflächen, Schulen und dergleichen, sind schallabsorbierende und/oder schalldämpfende Wände oder Bauelemente erforderlich, um eine Geräuschkulisse zu vermeiden, die den Unterricht, die Arbeit, Konferenzen und dergleichen stört.In buildings, especially in halls, offices, open spaces, schools and the like, sound-absorbing and/or sound-damping walls or building elements are required in order to avoid background noise that disturbs lessons, work, conferences and the like.
Es ist eine Vielzahl von schallabsorbierenden/schallreduzierenden Bauelementen bekannt.A large number of sound-absorbing/sound-reducing components are known.

In
Alle in diesen Veröffentlichungen beschriebenen Elemente absorbieren ein bestimmtes, sehr begrenztes Spektrum akustischer Wellen, und insbesondere tiefe Frequenzen werden nicht absorbiert.All elements described in these publications absorb a certain, very limited spectrum of acoustic waves, and especially low frequencies are not absorbed.
Das
Bei dieser Veröffentlichung stellt sich das Problem, dass zwei verschiedene Paneeltypen nebeneinander angeordnet werden müssen, insbesondere mit unterschiedlicher Dicke, was bei der Planung auf der Baustelle auch eine komplizierte Demontage nach der Montage erfordert.The problem with this publication is that two different types of panels have to be arranged side by side, in particular with different thicknesses, which also requires complicated disassembly after assembly when planning on site.
Darüber hinaus haben die bisher beschriebenen Paneele und Systeme eine relativ hohe Dichte und entsprechende Abmessungen, was zu einer Belastung der Konstruktion und auch zu einem Verlust an Innenraum führt, was zu einer Verschlechterung des Raumklimas o.ä. führen kann.In addition, the panels and systems described so far have a relatively high density and corresponding dimensions, which leads to a load on the structure and also to a loss of internal space, which can lead to a deterioration in the indoor climate or the like.
Ziel der vorliegenden Erfindung ist es, ein schallabsorbierendes System zu realisieren, das die verschiedenen Frequenzen absorbiert, eine einheitliche Oberfläche aufweist und vor Ort leicht installiert werden kann, ohne dass das System an die baulichen Gegebenheiten angepasst werden muss, und das ein geringeres Gewicht und eine geringere Größe, insbesondere eine geringere Dicke, aufweist.The aim of the present invention is to realize a sound-absorbing system that absorbs different frequencies, has a uniform surface, can be easily installed on site without the need to adapt the system to the structural conditions, and is lighter in weight and size, especially in thickness.
Dieses Ziel wird durch ein System gemäß dem kennzeichnenden Teil von Anspruch 1 erreicht.This object is achieved by a system according to the characterizing part of claim 1.

Diese Beschichtung wird aus einer Mischung von 300-700 g Baumwollmischung und 4-6 Litern Wasser pro m2 hergestellt, wobei die Baumwollmischung aus 80-95% Baumwollfasern oder einer Mischung aus Baumwolle und Holzfasern 80-95% und 5-18% Zellulose mit einer Faserlänge von 0,2-4 mm besteht.The system according to the invention consists of a support frame made of a metal profile, which is preferably arranged on a surface, an inner surface of a building.

This coating is made from a mixture of 300-700 g cotton blend and 4-6 liters of water per m 2 , the cotton blend being 80-95% cotton fibers or a blend of cotton and wood fibers 80-95% and 5-18% cellulose with a fiber length of 0.2-4 mm.

Die Paneele werden an einem Tragrahmen, z. B. einem profilierten Metall- oder Holzrahmen, befestigt. Der Abstand zwischen den Querträgern beträgt 40 bis 75 cm. Dadurch kann sich das beschichtete Paneel biegen und vibrieren, um den Schall besser zu absorbieren.The panels are attached to a support frame, e.g. B. a profiled metal or wooden frame attached. The distance between the crossbeams is 40 to 75 cm. This allows the coated panel to flex and vibrate to better absorb sound.
Mit Hilfe der Querträger werden die Paneele von der Oberfläche des Gebäudes beabstandet. Auf diese Weise entsteht zwischen den Querträgern jeweils eine Kammer, die teilweise mit Polyesterfaserpaneelen, Glasfaserpaneelen oder Holzfaserpaneelen ausgefüllt werden kann.With the help of the cross beams, the panels are spaced from the surface of the building. In this way, a chamber is created between the crossbeams, which can be partially filled with polyester fiber panels, glass fiber panels or wood fiber panels.
Der Tragrahmen welcher das System bildet kann Teil der Zwischendecke sein.The support frame that forms the system can be part of the false ceiling.
