Description

Die Erfindung bezieht sich auf ein akustisch wirksames Bauelement aus einer gelochten oder geschlitzten Tafel.The invention relates to an acoustically effective component made from a perforated or slotted panel.

Seit langem bekannt sind Bauelemente, die aus gelochten oder geschlitzten Platten aus dünnwandigen Blechen oder ähnlichen Materialien bestehen und als schallschluckende Montagedecke im Innenausbau mit Filzmatten aus Glas- oder Steinwolle hinterfüttert werden.Components made of perforated or slotted have long been known Plates made of thin-walled sheet metal or similar materials and used as a sound-absorbing mounting ceiling in the Interior fittings can be back-lined with felt mats made of glass or rock wool.

Die Schallschluckwirkung solcher Bauelemente hängt von verschiedenen Umständen ab und zwar besonders von dem sogenannten freien Querschnitt der Platten, also dem Verhältnis der Lochanteile zur gesamten Plattenfläche, der Stärke der eingebrachten Schallschluckfilze und vom Abstand zwischen der schallschluckenden Montagedecke und der schallharten Rohdecke des Bauwerkes.The sound-absorbing effect of such components depends on various Circumstances depend on the so-called free cross-section of the plates, i.e. the ratio of the hole proportions the entire panel surface, the thickness of the sound-absorbing felts and the distance between the sound-absorbing ceiling and the reverberant raw ceiling of the building.

Die aus Glas- oder Steinwolle bestehenden Schallschluckeinlagen sind nicht billig, und die auf den Baustellen auszuführenden Montagearbeiten zur Einbringung der Schallschluckfilze in die Decke sind vergleichsweise hoch, weil bekanntlich die Löhne der Bauarbeiter zu den höchsten gezählt werden müssen.The sound-absorbing inserts made of glass or rock wool are not cheap, and those to be carried out on the construction site Installation work to introduce the sound-absorbing felts into the ceiling is comparatively high because, as is well known, the wages of the Construction workers must be counted among the highest.

Die Verarbeitung der Schallschluckfilze ist außerdem insofern unangenehm und unter Umständen auch gesundheitsschädlich, als die kleinen Glasfasern der Glas- oder Steinwolle sehr brüchig sind und sich leicht bei der Verarbeitung in die Haut der Hände festsetzen und dort zu Geschwürsbidlungen führen können. Außerdem verursachen sie auch Reizerscheinungen in Nase, Mund und Rachen.The processing of the sound-absorbing felts is also uncomfortable in this respect and possibly also harmful to health, as the small glass fibers of the glass or rock wool are very brittle and can easily get stuck in the skin of the hands during processing and lead to ulcer formation there. aside from that they also cause irritation in the nose, mouth and throat.

Weiterhin müssen zur Herstellung der verschiedenen Schallschluckfilze die Grundmaterialien mit hohem Energieaufwand geschmolzen und in komplizierten Verfahren zu dünnen Fasern verarbeitet werden.You also need to manufacture the various sound-absorbing felts the basic materials are melted with a high expenditure of energy and processed into thin fibers in complex processes.

BAD ORIGINALBATH ORIGINAL

Der Erfindung liegt die Aufgabe zugrunde, ein akustisch wirksames Bauelement aus einer gelochten oder geschlitzten Tafel zu schaffen, bei dem die vorgenannten Nachteile vermieden werden.The invention is based on the object of creating an acoustically effective component from a perforated or slotted panel, in which the aforementioned disadvantages are avoided.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of claim 1.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen. Further features of the invention emerge from the subclaims.

Aufgrund von bisher wenig beachteter physikalischer Gesetze kann der Strömungswiderstand der bisher üblichen Schallschluckfilze beim Gegenstand der Erfindung dadurch erreicht und auf die bauseitig erforderlichen Wirkungsgrade eingestellt werden, indem dünnwandige gelochte Tafeln, vorzugsweise aus Blech, so mit porösen Stoffen, wie z.B. Papier, Vliesen oder Textilien, verbunden werden, daß im Bereich der Lochungen der Tafeln diese Stoffe trommelfellartig gespannt sind. Der hierdurch entstehende definierbare Strömungswiderstand kann durch Aufbringen von Füllstoffen auf das Vlies in beliebiger Weise manipuliert werden.Due to physical laws that have so far been neglected, the flow resistance of the previously customary sound absorbing felts achieved in the subject matter of the invention and on the Efficiency required on site can be set by thin-walled perforated boards, preferably made of sheet metal, connected to porous materials such as paper, fleece or textiles be that in the area of the perforations of the panels, these fabrics are stretched like a drumhead. The resulting definable Flow resistance can be manipulated in any way by applying fillers to the fleece.

Eine wesentliche Senkung der Herstellungskosten der erfindungsgemäßen Bauelemente entsteht dadurch, daß diese Bauelemente bereits im industriellen Produktionsablauf in jenen akustischen wirksamen Zustand versetzt werden, wie er bei der Verarbeitung auf der Baustelle nötig ist.A significant reduction in the manufacturing costs of the invention Components are created by the fact that these components already have an acoustic effect in the industrial production process State, as it is necessary for processing on the construction site.

Die Schallschluckwirkung des Bauelementes nach der Erfindung wird dadurch erreicht, daß im Bereich der Lochungen, die mit einem Faservlies trommelfeil artig überspannt sind, ein definierbarer Strömungswiderstand entsteht, der in akustisch/mathematischer Definier barkeit den störenden Schall in bestimmbarem Umfang vernichtet. Die Lochungen in der Tafel haben eine Düsenwirkung, dieThe sound-absorbing effect of the component according to the invention is achieved in that in the area of the perforations with a Fiber fleece are spanned like a drum file, a definable flow resistance arises, which in acoustic / mathematical Definability destroys the disturbing sound to a determinable extent. The perforations in the board have a nozzle effect that

durch das aufgebrachte Faservlies noch verstärkt wird. Das Faservlies verdichtet die Lochung der Tafel. Diese Düsenwirkung steht also im direkten Zusammenhang mit der Senkung des Lärmpegels im Raum.is reinforced by the applied fiber fleece. The fiber fleece compacts the perforation of the board. This nozzle effect is therefore directly related to the reduction in the noise level in the room.

Durch sinnvolle Manipulation des trommelfellartig gespannten Faservlieses kann der Strömungswiderstand erhöht und damit die Schallschluckwirkung (Schallabsorptionsgrad) in bestimmten Frequenzbereichen verändert werden.Sensible manipulation of the drumhead-like stretched fiber fleece can increase the flow resistance and thus the Sound absorption (sound absorption level) can be changed in certain frequency ranges.

Diese Manipulation kann z. B. durch Aufsprühen dichtender Stoffe auf das Faservlies erreicht werden. Diese dichtenden Stoffe verengen die Zwischenräume zwischen den Fasern des Vlieses und reduzieren dadurch den Strömungsfluß.This manipulation can e.g. B. can be achieved by spraying sealing substances on the nonwoven fabric. These sealing substances narrow the spaces between the fibers of the fleece and thereby reduce the flow of flow.

Durch Veränderung des freien Querschnitts der Lochungen des Bauelementes und einer entsprechenden Behandlung des über den Lochungen verspannten Faservlieses, kann mit Leichtigkeit die Schallschluckwirkung der bisher üblichen Akustikeinlage aus Steinoder Glaswolle in einer Stärke von 30mm erreicht werden. Das Bauelement nach der Erfindung hat vorzugsweise eine Stärke von unter lmm, jedoch die gleiche Wirkung bzw. besser als eine übliche Schallschluckplatte mit einer 30mm starken Schallschluckmatte aus Stein- oder Glaswolle.By changing the free cross section of the perforations of the component and a corresponding treatment of the Perforations of tensioned fiber fleece can easily reduce the sound-absorbing effect of the previously common acoustic insert made of stone or Glass wool with a thickness of 30mm can be achieved. The component according to the invention preferably has a thickness of less than 1mm, but the same effect or better than a usual one Sound absorbing plate with a 30mm thick sound absorbing mat made of rock or glass wool.
