Description
Schallschluckender Körper zur Bekleidung von Innenraumflächen Die Erfindung bezieht sich auf einen schallschluckenden, vorzugsweise plattenförmigen Körper aus Schaumstoff mit geschlossenen Poren, insbesondere Schaumpolystyrol, zur Bekleidung von Innenraumflachen.Sound-absorbing body for cladding interior surfaces The invention relates to a sound-absorbing, preferably plate-shaped Body made of foam with closed pores, in particular foam polystyrene, for Cladding of indoor areas.
Es sind bereits schallschluckende Platten aus Schaumkunststoff mit offenen Poren bekannt. Es handelt sich hierbei aber um Platten aus verhältnismäßig weichen Werkstoffen, die in nachteiliger Weise mit Verstrebungen oder anderen Verstärkungen versehen sein müssen, um das Durchbiegen, insbesondere bei ihrer Verwendung als Decken- oder Wandbekleidung, zu verhindern. Diese Verstrebungen beeinträchtigen die schallschluckende Wirkung derartiger Körper wesentlich. Auch bei einer unmittelbaren Befestigung derartiger Platten an der Wand, Decke od. dgl. wird der an sich günstige Schallschluckgrad erheblich erniedrigt.There are already sound-absorbing panels made of foam plastic with known open pores. However, these are plates made of relatively soft materials that are disadvantageous with bracing or other reinforcements must be provided to prevent deflection, especially when used as a Ceiling or wall cladding. These bracing interfere the sound-absorbing effect of such bodies is essential. Even with an immediate Attachment of such plates to the wall, ceiling or the like. The favorable in itself Degree of sound absorption significantly reduced.
Weiterhin sind Schaumkunststoffplatten auf der Basis von Polystyroi bekannt, die härter sind. Diese Platten haben aber den wesentlichen Nachteil, daß sie geschlossene Poren besitzen, so daß die Schallschluckwirkung nicht sehr groß ist.Furthermore, there are foam plastic plates based on polystyrene known to be harder. But these plates have the major disadvantage that they have closed pores, so that the sound-absorbing effect is not very great is.
Aufgabe der Erfindung ist es, das Schallschluckvermögen derartiger, vorzugsweise plattenförmiger Körper zu verbessern.The object of the invention is to improve the sound absorption capacity of such, preferably plate-shaped body to improve.
Dies wird gemäß der Erfindung durch zahlreiche eingestochene feine Löcher erreicht. Am besten reichen die Löcher bis etwa zur Hälfte der Körperdicke.According to the invention, this is illustrated by numerous pierced fine Holes reached. It is best if the holes are about half the thickness of the body.
Es sind zwar schon poröse schallschluckende Platten mit zahlreichen eingestochenen feinen Löchern bekanntgeworden, doch öffnen diese Löcher lediglich eine filmartige Oberflächenschicht, während die Erfindung darauf abzielt, den porösen Werkstoff selbst durch Öffnen zahlreicher seiner geschlossenen Poren für die Aufgabe der Porenschalldämpfung geeignet zu machen.There are already porous sound-absorbing plates with numerous pierced fine holes become known, but these holes only open a film-like surface layer, while the invention aims at the porous Material itself by opening numerous of its closed pores for the task to make the pore sound absorption suitable.
Ein schallschluckender Körper nach der Erfindung weist über die wichtigsten Frequenzen einen hohen Schallschluckgrad auf und ist einfach und billig herzustellen. Er läßt sich in Plattenform ohne Versteifungen bei verhältnismäßig geringer Werkstoffdicke, insbesondere als Wand- und Deckenbekleidung, gut verwenden.A sound-absorbing body according to the invention has the most important Frequencies have a high degree of sound absorption and is easy and cheap to manufacture. It can be used in the form of a plate without stiffening with a relatively small material thickness, Use particularly well as wall and ceiling coverings.
Träger solcher Platten kann die unmittelbare Oberfläche einer Wand oder einer Decke, eine Tapete, z-ine sonstige Papierschicht, eine Platte aus gleichem oder anderem Material, eine Verputzschicht oder eine Holzfläche sein. Die Platten lassen sich durch Ankleben, Ansintern oder Nageln befestigen. Ein schallschluckender Körper nach der Erfindung vereinigt die Vorteile eines verhältnismäßig harten, geschlossene Poren aufweisenden Werkstoffes mit denjenigen eines Werkstoffes, der offene Poren hat. Viele geschlossene Poren sind durchstochen, so daß dadurch Kanäle gebildet sind, die eine hohe schallschluckende Wirkung haben.Such panels can support the immediate surface of a wall or a blanket, wallpaper, another layer of paper, a sheet of the same or another material, a layer of plaster or a wooden surface. The plates can be attached by gluing, sintering or nailing. A sound absorbing one Body according to the invention combines the advantages of a relatively hard, closed Pore-having material with those of a material that has open pores Has. Many closed pores are pierced, so that channels are thereby formed which have a high sound-absorbing effect.
Vorteilhaft ist dabei, daß die Löcher bereits auf geringe Entfernung nach außen nicht mehr sichtbar sind so daß das architektonische Bild, beispielsweise einer Decke, in keiner Weise beeinträchtigt wird.The advantage here is that the holes are already at a short distance are no longer visible to the outside so that the architectural image, for example a ceiling, is not affected in any way.
Platten aus Schaurnpolystyrol sind verhältnismäßig hart und wasserabweisend; sie können mit einer gegebenenfalls feuerhemmenden porösen Farbschicht versehen sein.Sheets made of Schaurnpolystyrol are relatively hard and water-repellent; they can be provided with an optionally fire-retardant porous paint layer be.
