/ Schallabsorbierende Bauplatte ) / Sound-absorbing building board )

Bei der Erstellung von Gebäuden verwendet man zum Schutz von Räumen, wie z.B. Laden-, Schul-, Büro- und anderen Räumen,gegen Geräusche Mineralwolle und/oder Glaswolle enthaltende schallabsorbierende Platten.When creating buildings one uses for protection of rooms such as shops, schools, offices and other rooms, against noise mineral wool and / or glass wool containing sound-absorbing panels.

Das menschliche Ohr ist nicht für alle Geräusche gleich empfindlich. Besonders störend wirken Geräusche mit Frequenzen von 500 bis 5OOO Hz, vorzugsweise von etwa 3OOO Hz, Es gibt auch Platten, die eine verhältnismäßig gute Schalldämpfung bei 1000 bis 2500 Hz aufweisen, deren Absorptionskoeffizient jedoch bei Frequenzen über 25OO Hz stark abnimmt, so daß sie die gestellten Anforderungen nicht erfüllen.The human ear is not equally sensitive to all sounds. Noises with frequencies are particularly annoying from 500 to 500 Hz, preferably from about 300 Hz, There are also plates that have a relatively good sound attenuation at 1000 to 2500 Hz, their absorption coefficient but strong at frequencies above 2500 Hz decreases so that they do not meet the requirements.

7302557 26.08.767302557 08/26/76

Die Neuerung betrifft eine Platte mit beträchtlich verbessertem Absorptionskoeffizienten, die bei Frequenzen zwischen 500 und 7000 Hz einen konstanten hohen Wert aufweisen. Die Neuerung besteht darin, daß Mineralwolle und/oder Glaswolle zu einer Platte' von einem Gewicht von 70 bis 90 kg/m^ und einer Dicke von mindestens 15 1^ zusammengepreßt und ein- oder beidseitig mit einer Glasfaserhaut versehen ist. Die beispielsweise aus von einem organischen Bindemittel zusammengehaltenen Glasfasern bestehende Glasfaserhaut ist vorteilhaft mit einem Oberzug aus Lack versehen, der zweckmäßig nach dem Siebdruckverfahren aufgebracht sein kann. Das Siebdruckverfahren zum Aufbringen des Lacks auf der bereits mit einer Glasfaserhaut versehenen Mineralwoll- oder Glaswollplatte hat gegenüber einem Spritzverfahren den Vorteil, daß mit ihm eine gleichmäßigere Verteilung des Lacks über der Platte entsprechend einem konstanten Muster erzielt wird.The innovation relates to a plate with a considerably improved absorption coefficient, which has a constant high value at frequencies between 500 and 7000 Hz. The innovation consists in the fact that mineral wool and / or glass wool are pressed together to form a plate with a weight of 70 to 90 kg / m ^ and a thickness of at least 15 1 ^ and is provided with a glass fiber skin on one or both sides. The glass fiber skin, for example consisting of glass fibers held together by an organic binder, is advantageously provided with a coating of lacquer, which can expediently be applied by the screen printing process. The screen printing process for applying the lacquer to the mineral wool or glass wool plate already provided with a fiberglass skin has the advantage over a spraying process that it achieves a more even distribution of the lacquer over the plate according to a constant pattern.

Die neuerungsgemäße Platte besitzt vorteilhaft eine mit Lack versehene Faserhaut mit einer Oberfläche, die etwas größer ist als die der Platte und um die Platte herumgeschlagen und auf ihrer Rundfläche vermittels eines auf der Innenseite der Glasfaserhaut angeordneten Streifens aus Metall, z.B. Aluminium, gehaltert ist.The plate according to the innovation advantageously has a fiber skin provided with lacquer with a surface which is slightly larger than that of the plate and wrapped around the plate and mediated on its round surface one arranged on the inside of the fiberglass skin Strip made of metal, e.g. aluminum, is held.

wobei sie zweckmäßig in einem Einlageprofil untergebracht werden, so daß sie ein schönes Ganzes bilden und die Nähte zwischen ihnen nahezu nicht sichtbar sind. Die Glasfaserhaut auf der Mineral- bzw. Glaswollplatte ist zweckmäßig vermittels eines Leimes erfolgt, wozu jeder im Handel befindliche Klebstoff zur Anwendung kommen kann. Vorzugsweise kommen synthetische Klebstoffe in Betracht.where they are conveniently housed in an insert profile so that they form a beautiful whole and the seams between them are almost invisible are. The fiberglass skin on the mineral or glass wool plate is expediently done by means of a glue, for which every commercially available adhesive can be used. Synthetic adhesives are preferred into consideration.

Die mit neuerungsgemäß ausgebildeten Platten erstellten Decken haben eine vorzügliche Schallabsorptionswirkung und besitzen auch gute Feuerschutz- und Wärmeisolierungseigenschaften. Durch ihre Anbringung kann die Geräuschbelästigung in Fabrikhallen, Büros, Läden, Schulen, Krankenhäusern und dgl. weitgehend vermindert oder sogar vollkommen behoben werden.The ceilings made with panels designed according to the new design have an excellent sound absorption effect and also have good fire protection and thermal insulation properties. Attaching them can reduce the noise nuisance in factories, offices, shops, schools, hospitals and the like. Largely reduced or even be completely fixed.

Die neuen Platten sind vorzugsweise zu einer Stärke von etwa 25 mm und zu einem Gewicht von etwa 75 kg/m zusammengepreßt. Die an Deckenplatten dieser Ausbildung, die auf einer Seite mit einer Glasfaserhaut versehen waren, mit einem Luftspalt von etwa 2 cm durchgeführten Messungen der Schallabsorption ergeben die nachfolgenden Werte:The new panels are preferably compressed to a thickness of about 25 mm and a weight of about 75 kg / m. Those on ceiling panels of this design, which were provided with a fiberglass skin on one side, Measurements of sound absorption carried out with an air gap of about 2 cm give the following values:

Aus den aus der Tabelle ersichtlichen Werten ist erkennbar, daß die Platten nach der Neuerung in dem hinderlichen Schallgebiet zwischen 500 und 5000 Hz eins vorzügliche und gleichmäßige Schallabsorption aufweisen und daß insbesondere über 3000 Hz die Schallabsorption zugenommen hat.From the values shown in the table it can be seen that the plates after the innovation in the obstructive Sound area between 500 and 5000 Hz is an excellent one and have uniform sound absorption and that in particular above 3000 Hz the sound absorption increased Has.
