Description

Es ist bekannt, daß die Schalldämmung von Trennwänden in erster Linie von der Masse der Trennwand pro Flächeneinheit abhängt. Diese Massenwirkung wird durch die Steifigkeit der Trennwände, die physikalisch als Platten anzusehen sind, verringert, wenn Schallwellen schräg auf sie auffallen. Um diesen sogenannten Koinzidenzeffekt zu vermeiden oder wenigstens herabzusetzen, wurden verschiedene Vorschläge gemacht, die darauf hinauslaufen, das Verhältnis der Steife zur Masse pro Flächeneinheit entweder groß, z. B. durch Aufsetzen von Leisten oder ähnlichen Profilen, oder klein zu machen, also die Masse zu erhöhen. Diese Massenerhöhung erfolgte in allen Fällen dadurch, daß zusätzlich beschwerende Massen in Form von Einzelkörpern entweder auf die Platte aufgesetzt oder in das Plattenmaterial eingearbeitet wurden. Dabei blieb die ursprüngliche Steife der Platte erhalten, und nur ihre Masse wurde erhöht. Außerdem wurde auch schon vorgeschlagen, außer der Massenerhöhung die Platte selbst aus biegeweichem Werkstoff, d. h. aus einem Werkstoff mit niedrigem Elastizitätsmodul, herzustellen.It is known that the sound insulation of partition walls depends primarily on the mass of the partition wall per unit area. This mass effect is due to the rigidity of the partition walls, which are physically are to be regarded as plates, reduced if sound waves strike them at an angle. To this one Various proposals have been made to avoid or at least reduce the so-called coincidence effect which boils down to the ratio of stiffness to mass per unit area either large, e.g. B. by putting on strips or similar profiles, or to make small, so the Increase mass. This increase in mass took place in all cases by additionally burdening Masses in the form of individual bodies either placed on the plate or incorporated into the plate material became. The original stiffness of the plate was retained and only its mass was increased elevated. In addition, it has also already been suggested, in addition to increasing the mass, the plate itself flexible material, d. H. from a material with a low modulus of elasticity.

Die bekannten Platten sind im allgemeinen reichlich mühsam und kostspielig herzustellen und haben als Bauteil oft ein unschönes Aussehen, da eine regelmäßige Anordnung der beschwerenden Einzelmassen wegen Spurwellen, Resonanzen und Gitterwirkungen aus akustischen Gründen vermieden werden muß.The known panels are generally quite laborious and expensive to manufacture and have as a component, it often looks unattractive because of the regular arrangement of the weighting individual masses must be avoided because of track waves, resonances and grid effects for acoustic reasons.

Außerdem werden die zu erwartenden Dämmwerte bei den bekannten Platten nicht erreicht, wenn die beschwerenden Einzelmassen Lücken offenlassen, in denen das Wandmaterial ungehindert schwingen kann, und dadurch in bestimmten Frequenzbereichen Einbrüche in der Dämmkurve entstehen.In addition, the expected insulation values are not achieved with the known panels if the Weighing individual masses leave gaps open in which the wall material can vibrate unhindered This can result in drops in the insulation curve in certain frequency ranges.

Der Erfindung liegt die Aufgabe zugrunde, die Mängel der bekannten Platten bezüglich der Luftschalldämmung zu überwinden und eine optimale Luftschalldämmung zu erreichen.The invention is based on the problem of the shortcomings of the known panels with regard to airborne sound insulation to overcome and achieve optimal airborne sound insulation.

Die Erfindung besteht in der Anwendung eines biegeweich erstarrten, einen beschwerenden Werkstoff in feiner Verteilung enthaltenden, vorzugsweise folien- oder mattenartigen Flächenmaterials für die Luftschalldämmung. Ein solches Material war bisher nur als Entdröhnungsmittel bekannt. Es handelt sich dabei um eine auf die Innenwandungen eines Fahrzeuges in festem oder flüssigem Zustand oder als Folie oder Bahn aufgebrachte Schicht zum Dämpfen der von den selbstschwingenden Wandungen erzeugten Geräusche, die als Grundstoff Polymerisationskunststoffe mit großer Dehnungsfestigkeit und Zusätze von Füllstoffen mit hohem spezifischem Gewicht enthält, z.B. inForm von getrocknetemEisenoxydschlamm.The invention consists in the use of a flexurally soft solidified, a weighting material in a fine distribution containing, preferably sheet or mat-like sheet material for the Airborne sound insulation. Such a material was previously only known as an anti-drumming agent. It is about one on the inner walls of a vehicle layer applied in solid or liquid state or as a film or sheet for damping purposes the noises generated by the self-oscillating walls, the polymerisation plastics with high tensile strength and additives as a base material of fillers with high specific gravity, e.g. in the form of dried iron oxide sludge.

Besondere Vorteile bieten sich in der praktischen Anwendung des Flächenmaterials als schalldämmende Matte im Hochbau, z. B. bei der akustischen Abkapselung oder Trennung von Maschinen- oder Motorenständen von deren Bedienungsständen, auch in Kranen und Baggern, bei denen seither Motor- und Bedienungsstand in einem Haus untergebracht waren. Man kann in diesen und ähnlichen Fällen die beschriebene Matte als abschirmenden Vorhang zwischen Maschinisten und Motor aufhängen. Insbesondere kann in solchen Fällen die Matte als aufwickelbarer Vorhang ausgebildet werden.There are particular advantages in the practical use of the sheet material as a sound-absorbing material Mat in building construction, e.g. B. in the acoustic encapsulation or separation of machine or Engine stands from their control stations, also in cranes and excavators, where since then engine and Control station were housed in a house. In these and similar cases, the described Hang up the mat as a shielding curtain between the machinist and the engine. In particular In such cases, the mat can be designed as a roll-up curtain.

Während bei Platten Koinzidenzen grundsätzlich immer auftreten, können sie bei Membranen von vornherein auf einfache Weise vermieden werden.While coincidences always occur in the case of plates, they can occur in the case of membranes of can be avoided from the outset in a simple manner.

Der Koinzidenzeffekt läßt sich völlig vermeiden, wenn das schwere, biegeweiche Flächenmaterial als Membran in einen Rahmen eingespannt wird. Die Membranenspannung soll möglichst gering sein. Der Rahmen kann unter Umständen längs oder quer in beiden Richtungen unterteilt sein.The coincidence effect can be completely avoided if the heavy, flexible sheet material as Membrane is clamped in a frame. The membrane tension should be as low as possible. Of the Under certain circumstances, the frame can be divided longitudinally or transversely in both directions.

Wird es insbesondere notwendig, das hier beschriebene Flächenmaterial zur Verbesserung der Luftschalldämmwirkung einer bereits bestehenden Wand zu benutzen, so geschieht dies erfindungsgemäß derart, daß, sofern die bereits bestehende Wand leicht ist, das Material direkt auf die bestehende Wand aufgeklebt wird und, sofern die bereits bestehende Wand schwer ist, das Material unter Belassung eines Abstandes vor der Wand angeordnet wird. Dabei kann der entstehende Hohlraum entweder frei bleiben oder mit einer federnden Schicht, z. B. aus Filz, Schaumstoff, Mineralwolle oder ähnlichem, ausgefüllt werden.It is particularly necessary to use the sheet material described here to improve the airborne sound insulation effect to use an existing wall, this is done according to the invention in such a way that that, if the existing wall is light, the material is glued directly onto the existing wall and, if the existing wall is heavy, the material leaving a gap is placed in front of the wall. The resulting cavity can either remain free or with a resilient layer, e.g. B. made of felt, foam, mineral wool or the like, are filled.

Diese federnde Schicht kann auch mit dem schalldämmenden Material zu einer Einheit verbunden sein, die als Matte hergestellt und eingebaut wird.This resilient layer can also be connected to the sound-absorbing material to form a unit, which is manufactured and installed as a mat.

Außerdem ist es für viele Anwendungsfälle zweckmäßig, das schalldämmende Flächenmaterial auf eine Trägermatte oder -folie von hoher Zerreißfestigkeit aufzubringen. Dies kann bereits bei der Herstellung geschehen, indem der mit den schweren Substanzen gemischte pastenförmige Stoff auf die zerreißfeste Trägerfolie, die z. B. aus einer Kunststoffolie oder einem Textilgewebe bestehen kann, aufgebracht wird, beispielsweise durch Aufspritzen, Aufspachteln, Streichen oder Walzen.In addition, it is useful for many applications, the sound-absorbing sheet material on a To apply carrier mat or film of high tensile strength. This can be done during manufacture done by placing the paste-like substance mixed with the heavy substances on the tear-resistant Carrier film, the z. B. can consist of a plastic film or a textile fabric is applied, for example by spraying, troweling, brushing or rolling.

Als beschwerender Werkstoff für das luftschalldämmende Flächenmaterial kommen z. B. handeisübliche Pulver von Schwermetallen, wie Wismut oder Blei, in Frage, die unter anderem auch als Abfall anfallen. Außerdem können Pulver von schweren Mineralien verwendet werden, z. B. solche von Schwerspat oder Zinnober.As a weighting material for the airborne sound insulating Sheet material come z. B. commercial powder of heavy metals such as bismuth or Lead, which is also incurred as waste, among other things. Also, powder can be heavy Minerals are used, e.g. B. those of barite or cinnabar.

Als biegeweiche Werkstoffe, die als Träger für die beschwerenden Materialien wirken, können hochpolymere Kunststoffe, verwendet werden, die entweder trocknen, z. B. Kunststoffdispersionen oder -lösungen, oder anderweitig aushärten, wie z. B. Polyester.As flexible materials that act as a carrier for the weighting materials, high polymer Plastics, are used that either dry, e.g. B. plastic dispersions or solutions, or otherwise harden, such as. B. polyester.

Unter Umständen können statt hochpolymerer Kunst- oder Naturstoffe, wie z. B. Kautschuk, auch Bitumen, bitumenähnliche Stoffe wie Asphalt oder Pech verwendet werden.Under certain circumstances, instead of high-polymer plastics or natural materials, such as. B. rubber, too Bitumen, bitumen-like substances such as asphalt or pitch can be used.

Die beschwerenden Pulver können durch Rühren oder Walzen in einem pastenartigen Stoff homogen verteilt werden, z. B. so, daß die Pulver in einer Kunststoffdispersion oder -lösung eingerührt oder in eine Kautschukmatte eingewalzt werden.The weighting powders can be made homogeneous in a paste-like substance by stirring or rolling be distributed, e.g. B. so that the powder is stirred into a plastic dispersion or solution or in a rubber mat can be rolled in.

So kann man z. B. 80 g Bleipulver und 20 g Kunststoffemulsion sämig verrühren und auf eine Trägerfolie aufspritzen und anschließend trocknen lassen.So you can z. B. 80 g of lead powder and 20 g of plastic emulsion stir until creamy and pour on a Spray on the carrier film and then let it dry.

Eine weitere Möglichkeit zur Herstellung des schalldämmenden Flächenmaterials besteht darin, daß in einem Verdünnungsmittel, z. B. einer Kunststoffdispersion, lösliche Schwermetallverbindungen, z. B. Bleizucker, gelöst werden. In diesem Falle nimmt die homogene Verteilung die feinstmögliche Verteilungsform an, nämlich eine gleichmäßige molekulare Ver- teilung" des schweren Stoffes über die ganze Hache. Diese Lösung läßt man trocknen, so daß dann eine schwere biegeweiche Kunststoffmatte oder -folie entsteht.Another possibility for producing the sound-absorbing sheet material is that in a diluent, e.g. B. a plastic dispersion, soluble heavy metal compounds, e.g. B. Lead sugar, to be dissolved. In this case, the homogeneous distribution takes on the finest possible distribution form, namely a uniform molecular distribution division "of the heavy material over the whole Hache. This solution is allowed to dry, so that then a heavy pliable plastic mat or sheet arises.

In allen diesen Fällen wird angestrebt, eine biegeweiche Matte oder Folie herzustellen, die ein möglichst großes Gewicht je Flächeneinheit hat.In all of these cases, the aim is to produce a pliable mat or film that is as flexible as possible has great weight per unit area.
