Description
Vorliegende Erfindung bezieht sich auf eine schalldämpfende Wand- und Deckenbekleidung. Das Wesen der Erfindung wird darin erblickt, einen tonaufsaugenden Wand- oder Deckenputz aus mineralischen oder organischen Fasern, einem Klebemittel und Wasser herzustellen und mit einem innig mit dem tonaufsaugenden Baustoff in Verbindung zu bringenden Ueberzug zu versehen, der aus einer nicht absorbierenden, jedoch perforierten Masse aus Papier, Textilstoff, Metall, Holz, Kunststoff, Lacken oder dergl. besteht. Naturgemäss können auch aus Glaswolle, einem Bindemittel etc. hergestellte Bauplatten schon bei ihrer Herstellung mit unlösbaren, perforierten Ueberzügen aus einer nicht schalldämpfenden Masse versehen werden.The present invention relates to sound-absorbing wall and ceiling coverings. The essence of the invention is seen in the production of a clay-absorbing wall or ceiling plaster from mineral or organic fibers, an adhesive and water and to provide it with a coating that is intimately connected with the clay-absorbing building material, which consists of a non-absorbent, but perforated mass Made of paper, textile, metal, wood, plastic, paints or the like. Consists. Naturally, building boards made of glass wool, a binding agent, etc. can be provided with permanent, perforated coatings made of a non-sound-absorbing compound during their production.
Es sind bereits schalldämpfende Wand- und Deckenbekleidungen bekannt geworden, bei denen als Verkleidung der schalldämpfenden Schicht eine dünne, den Schall nicht absorbierende, metallische Platte benutzt wird, die Lochungen aufweist, deren Durchmesser grösser sind, als die Stärke der Platte beträgt. Im Zuge der praktischen Weiterentwicklung und Erfahrungen dieser einschlägigen Technik ist man jedoch von der Anordnung solcher von der schallabsorbierenden WandSound-absorbing wall and ceiling coverings have already become known in which a thin, sound-absorbing metallic plate is used as cladding of the sound-absorbing layer, which has holes whose diameter is larger than the thickness of the plate. In the course of practical further development and experience of this relevant technology, however, one is of the arrangement of such from the sound-absorbing wall
Abstand aufweisender, selbständiger Isolierplatten abgerückt, da deren Wirkungsgrad keineswegs befriedigend war. Aufgrund einer Reihe von Versuchen ist man zu der eigentlich nicht zu erwartenden und somit überraschenden Kenntnis gekommen, dass die Absorptionswirkung ganz wesentlich erhöht wird, wenn man schalldämpfende Wandoberflächen beispielsweise aus einem porösen Mörtelputz mit perforierten, flächenförmigen Gebilden aus Papier, Textilien, Metallfolien, Holzplatten, Kunstharzmasse oder dergl. derart versieht, dass beide Teile eine innige körperliche Verbindung miteinander erhalten. Eine solche innige Verbindung kann z.B. dadurch erzielt werden, dass man auf den Glaswoll- oder dergl. Putz perforierte Papierbahnen aufklebt, man kann aber auch eine nicht schalldämpfende Ueberzugsschicht so auf dem Glaswollputz oberflächenartig erzeugen, indem man diesen unter Zwischenschaltung einer entsprechend perforierten Schablone mit einem filmbildenden Lack bzw. einer Kunstharzlösung streicht oder überspritzt.Separate, independent insulating panels moved away because their efficiency was by no means satisfactory. As a result of a series of experiments, the unexpected and therefore surprising knowledge came about that the absorption effect is significantly increased if sound-absorbing wall surfaces are made of, for example, a porous mortar plaster with perforated, sheet-like structures made of paper, textiles, metal foils, wooden panels, Synthetic resin compound or the like. Provides such that both parts receive an intimate physical connection with each other. Such an intimate connection can be achieved, for example, by gluing perforated paper webs onto the glass wool or similar plaster, but you can also create a non-sound-absorbing coating layer on the glass wool plaster like a surface by interposing a correspondingly perforated stencil with a film-forming lacquer or a synthetic resin solution is painted or sprayed over.
Die Praxis hat gelehrt, dass eine lose Verbindung zwischen einem tonaufsaugenden Stoff und einem nicht tonaufsaugenden Ueberzug sogar eine Verminderung der angestrebten Schallabsorptionswirkung nach sich zieht, und dass nur durch eine feste körperliche Verbindung beider, schalltechnisch verschieden wirkender Stoffe der erfindungsbedingte Effekt erzielt wird, der darin besteht, eine ausgezeichnete und gleichmässige Absorptionswirkung für Frequenzen auf breitester Basis zu erzielen. Die Grösse, die Anordnung und die Anzahl der schalldurchlässigen Perforationen kann von Fall zu Fall anhand vonPractice has taught that a loose connection between a sound-absorbing substance and a non-sound-absorbing cover even leads to a reduction in the desired sound absorption effect, and that the effect of the invention is only achieved through a firm physical connection between the two substances, which have different acoustic effects exists to achieve an excellent and even absorption effect for frequencies on the broadest basis. The size, the arrangement and the number of the sound-permeable perforations can be based on from case to case
Versuchen und Messungen bestimmt werden. Durch das geringe spezifische Gewicht der erfindungsgemässen Ueberzüge können dieselben in allen Fällen, wie z.B. bei freitragenden Decken usw. ohne Komplikationen Anwendung finden. Die Ueberzugsstoffe können natürlich beliebig gefärbt bzw. gemustert werden und verleihen dadurch dem porösen Verputz ein schönes Aussehen.Trials and measurements are determined. Due to the low specific weight of the coatings according to the invention, they can be used without complications in all cases, such as with self-supporting ceilings, etc. The covering materials can of course be colored or patterned as desired and thereby give the porous plaster a beautiful appearance.
