Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur
Verminderung von Schallpegeln in Gebäuden nach dem
Oberbegriff des Patentanspruches 1.The invention relates to a device for
Reduction of noise levels in buildings after
Preamble of
In der DE 44 37 196 C1 wird ein schallabsorbierendes Kunstglasbauteil beschrieben, welches aus wenigstens zwei gelochten Kunststoffplatten besteht, zwischen denen zum Beispiel Papierstreifen oder Folien aus einem anderen Werkstoff als Abstandhalter angeordnet sind, und deren Lochungen nicht in gegenseitiger Überdeckung liegen. Die Wirkung solcher Vorrichtungen zur Schallabsorption beruht nach den Darlegungen im Text dieser Druckschrift darauf, daß in einer Vielzahl von durch die Lochungen gebildeten Hohlräumen eine Absorption von Schallwellen vor einer schallharten Begrenzungswand im hörbaren Frequenzbereich stattfindet.DE 44 37 196 C1 is a sound absorbing Artificial glass component described, which consists of at least two perforated plastic plates, between which to Example paper strips or foils from another Material are arranged as spacers, and their Perforations are not mutually overlapping. The Effect of such devices for sound absorption is based according to the explanations in the text of this document, that in a variety of formed by the perforations Cavities an absorption of sound waves in front of a reverberant boundary wall in the audible frequency range takes place.
Aus der DE 43 15 759 C1 sind auch mikroperforierte Platten mit kleinen Durchmessern der Lochungen für den Aufbau einer Vorrichtung zur Schallabsorption bekannt.DE 43 15 759 C1 are also micro-perforated Slabs with small diameters for the holes Structure of a device for sound absorption is known.
Die DE 44 08 782 A1 offenbart einen sogenannten Folienabsorber, bei dem mehrere Folien lagenweise übereinander gespannt sind. Dieses Folienpaket ist seinerseits vor eine schallharte Wand gespannt. Jede Folie bildet mit der hinter ihr angeordneten Luft ein Feder-Masse-System, welches Schall im Bereich seiner Resonazfrequenz absorbiert. Um eine möglichst breitbandige Schallabsorption zu erhalten, sind viele Lagen luftundurchlässiger Folien erforderlich.DE 44 08 782 A1 discloses a so-called Foil absorber, in which several foils in layers are stretched over each other. This foil package is in turn stretched against a reverberant wall. Each Foil forms with the air behind it Spring mass system, which sound in the area of its Resonance frequency absorbed. To one if possible There are many to obtain broadband sound absorption Layers of airtight foils are required.
Durch die DE 42 20 434 A1 wird eine Schallschutzvorrichtung für Gebäude offenbart, welche aus einer schallabsorbierenden Folie besteht, die an ihren Seitenkanten von Dichtlippen eines Profilrahmens eingefaßt ist, welcher zur Schallisolierung dicht vor einer Fenster- oder Türöffnung eines Gebäudes angeordnet wird.DE 42 20 434 A1 is a Soundproofing device for buildings disclosed which a sound absorbing film, which is attached to their Side edges of sealing lips of a profile frame is bordered, which is close to the sound insulation a window or door opening of a building becomes.
Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstig herstellbare und vielseitig einsetzbare Vorrichtung zur Schalldämmung in Räumen eines Gebäudes zu gestalten, die möglichst leicht an sich ändernde Bedarfsfälle angepaßt werden kann und eine breitbandige Schallabsorption gewährleistet.The invention has for its object a inexpensive to manufacture and versatile Device for sound insulation in rooms of a building too design that changing as easily as possible Needs can be adjusted and a broadband Sound absorption guaranteed.
Erfindungsgemäß wird zur Lösung dieser Aufgabe eine
Ausbildung mit den Merkmalen nach dem Patentanspruch 1
vorgeschlagen. According to the invention a solution to this problem
Training with the features of
Mit diesen Ausbildungsmerkmalen lassen sich unter Vermeidung von Mineralwolle für die Schallabsorption beliebig figurierte Schalldämpfungselemente gestalten, die in Räumen an Wänden oder Decken mit Abständen voneinander befestigt werden. Diese Befestigung erfolgt vorzugsweise im Überkopfbereich der sich in dem Raum aufhaltenden Personen durch Aufhängung an der Decke oder anderweitige Befestigung an einer Wand oder Einbauten des Gebäuderaumes. Die Schallabsorption beruht hier auf dem Schwingen der Luft in den Löchern der Microperforation. Für den Fachmann überraschend schwingt die Luft dabei in den dünnen Folien (Dicke bis 1 mm) ohne Abriß. Eine eventuelle Luftdurchspülung bei in mehreren Lagen angeordneten Folien ist auf die Schallabsorption ohne Einfluß. Der Schallabsorptionseffekt ist vom Material der Folie unabhängig. Es eignen sich Kunststoffolien genauso wie Metallfolien. Die Folien können gespannt sein oder lose hängen bzw. flexibel bleiben. Auf die Schallabsorption hat die Spannung bzw. Flexibilität der Folie keinen Einfluß. Vorzugsweise geeignet sind Vorrichtungen zur Verminderung von Schallpegeln mit den Erfindungsmerkmalen zur Anwendung in Schwimmbädern oder in Werkhallen, in denen Nachhallzeiten reduziert werden sollen. Möglich ist auch die Kombination von Licht- und Schallschutz mit Vorrichtungen gemäß der Erfindung.With these training features can be under Avoidance of mineral wool for sound absorption design soundproofing elements in any shape, those in rooms on walls or ceilings with intervals be attached from each other. This attachment is done preferably in the overhead area of the room people by hanging from the ceiling or otherwise attached to a wall or internals of the Building room. The sound absorption here is based on the Swinging air in the holes of the microperforation. Surprisingly for the expert, the air swings in the thin foils (thickness up to 1 mm) without tearing. A possible air purging in several layers arranged foils is without the sound absorption Influence. The sound absorption effect is from the material of the Slide independently. Plastic films are also suitable like metal foils. The foils can be stretched or hang loose or stay flexible. On the Sound absorption has the tension or flexibility of Slide no influence. Are preferably suitable Devices for reducing sound levels with the Features of the invention for use in swimming pools or in workshops where reverberation times are reduced should. It is also possible to combine light and Soundproofing with devices according to the invention.
Vorzugsweise werden zwei oder mehr mikroperforierte Folien mit einem Abstand voneinander und parallel zueinander in einem oberen Träger aus einem biegesteifen Werkstoff und einem unteren, ebenfalls aus einem biegesteifen Werkstoff bestehenden Träger gespannt, so daß die Folien durch das Gewicht des unteren Trägers belastet sind. Mehrere perforierte Folien können mit einem Abstand voneinander paketweise zwischen einem gemeinsamen oberen Träger und einem gemeinsamen unteren Träger angeordnet sein. Preferably two or more are micro-perforated Foils spaced apart and parallel to each other in an upper beam made of a rigid Material and a lower one, also from one rigid material existing carrier tensioned, so that the slides by the weight of the lower beam are burdened. Several perforated foils can be used a distance from each other in packets between one common upper beam and a common lower one Carrier be arranged.
Aus Sicherheitsgründen sollten zwischen dem oberen Träger und dem unteren Träger zugfeste Sicherungsglieder vorgesehen sein, um bei einem eventuellen Bruch der Folien, zum Beispiel infolge unsachgemäßer Behandlung, das Herabstürzen des unteren Trägers zu verhindern. Vorrichtungen zur Schalldämpfung mit den Erfindungsmerkmalen werden entweder einzeln oder zu mehreren hintereinander schürzenartig im Überkopfbereich eines Raumes hängend oder an Einbauten befestigt.For security reasons, should be between the top bracket and the lower beam tensile securing members to be provided in the event of a possible breakage of the Foils, for example as a result of improper handling, to prevent the lower beam from falling. Soundproofing devices with the Invention features are either individually or too several in a row like aprons in the overhead area hanging in a room or attached to fixtures.
Eine weitere Ausgestaltung der Erfindungsmerkmale sieht vor, daß die Befestigung der mikroperforierten Folien in dem oberen Träger jeweils an einer verdrehbaren Rolle erfolgt, so daß die Folien teilweise oder ganz auf diese Rolle aufgewickelt werden können, um dadurch einerseits die Einstellung optimaler schalldämpfender Wirkungen zu erreichen und andererseits Anpassungen an nutzungsbedingte Freiräume in dem Raum zu ermöglichen.Another embodiment of the features of the invention provides before attaching the microperforated sheets in the upper beam on a rotatable roller takes place so that the films partially or entirely on this Roll can be wound up to make one hand the setting of optimal sound absorbing effects achieve and on the other hand adaptations allow usage-related free spaces in the room.
Weitere Merkmale beziehen sich auf die Ausgestaltung der Folie.Other features relate to the design of the Foil.

Die Vorrichtung zur Verminderung von Schallpegeln in
Gebäuden oder dergleichen besteht aus einem oder aus
mehreren in Nachbarschaft zueinander angeordneten
Schalldämpfungselementen 1. Jedes Schalldämpfungselement
1 ist aus paketweise angeordneten Folien 2 mit einer
Mikroperforation aufgebaut, wobei zwei oder mehr
mikroperforierte Folien 2 parallel zueinander und mit
einem Abstand voneinander zwischen einem oberen Träger 3
aus einem biegesteifen Werkstoff, zum Beispiel Metall,
Kunststoff oder auch Holz, und einem unteren Träger 4,
welcher ebenfalls aus einem biegesteifen Werkstoff
besteht, gespannt sind. Die Folien 2 eines
Schalldämpfungselementes 1 weisen somit einen gemeinsamen
oberen Träger 3 und einen gemeinsamen unteren Träger 4
auf. Der Abstand der Folien 2 voneinander in horizontaler
Richtung kann durch Zwischenlagen der Träger 3 und 4
erreicht werden, wie es in der Zeichnung dargestellt ist.
Aus Sicherheitsgründen ist der untere Träger 4 mit dem
oberen Träger 3 eines jeden Schalldämpfungselementes 1
durch ein zugfestes Sicherungsglied 5, beispielsweise
durch in Abständen angeordnete Drahtseile, miteinander
verbunden.The device for reducing sound levels in
Buildings or the like consists of or
several arranged in proximity to each
Das Beispiel in der Figur 1 zeigt die hängende
Befestigung mehrerer Schalldämmelemente 1 in
unmittelbarer Nachbarschaft zueinander und in
schürzenartiger Anordnung. Der obere Träger 3 jedes
Schalldämpfungselementes 1 ist mittels U-förmiger
Tragbügel 6 an Hängeseilen 7, Ketten oder Laschen
befestigt. Die Figur 2 veranschaulicht die starre
Befestigung eines Schalldämpfungselementes 1 an einer
Wand, einem Deckenvorsprung oder an einem anderen festen
Bauteil innerhalb eines Gebäuderaumes, zum Beispiel
mittels abgeknickter Befestigungsschellen 8, welche mit
der Gebäudewand 9 oder dergleichen verschraubt sind.The example in Figure 1 shows the hanging
Attachment of
Die Figur 4 veranschaulicht schematisch die Anordnung von
Wickelrollen 10 innerhalb des oberen Trägers 3, wobei
jede mikroperforierte Folie 2 mit ihrem oberen Ende auf
eine solche Wickelrolle 10 aufläuft, so daß die
herabhängende und somit wirksame Folienlänge verändert
werden kann, wie es zuvor bereits erläutert wurde.
Gegebenenfalls kann auch das zugfeste Sicherungsglied 5
mit einer entsprechenden Aufwickelvorrichtung kombiniert
sein.Figure 4 schematically illustrates the arrangement of
Die Folien 2 weisen bei allen Ausführungsbeispielen eine
Dicke bis zu (kleiner/gleich) 1 mm auf. Die
Microperforation ist durch Löcher mit einem Durchmesser
von 0,1 bis 0,4 mm gebildet. Der freie Querschnitt, also
die Summe aller Lochquerschnitte, beträgt 0,7 bis 1,5 %.
Dabei gilt, daß mit steigender Foliendicke auch der
Lochdurchmesser steigen kann. Je kleiner also die
Foliendicke ist, desto kleiner sollte auch der
Lochdurchmesser gewählt werden, um gute
Absorptionsergebnisse zu erzielen. Die oben genannte
Obergrenze für den Lochdurchmesser von 0,4 mm gilt
demnach für Folien mit einer Dicke von nahezu 1 mm. Der
freie Querschnitt kann unabhängig von der Foliendicke
gewählt werden.The
Einen konkreten Anwendungsfall zeigt Fig. 5. Zwei Lagen von microperforierten Folien 2.1 und 2.2 sind vor einer schallharten Wand 9 oder einem Fenster angeordnet. Der Abstand der ersten Folienlage 2.1 zur Wand 9 bzw. dem Fenster beträgt 100 mm. Der Abstand der beiden Folienlagen 2.1 und 2.2 zueinander beträgt 30 mm.Fig. 5 shows a specific application. Two layers of microperforated foils 2.1 and 2.2 are in front of one hard wall 9 or a window arranged. Of the Distance of the first film layer 2.1 to the wall 9 or the Window is 100 mm. The distance between the two Foil layers 2.1 and 2.2 to each other is 30 mm.
Für die Folien selbst wurden unterschiedliche
Ausgestaltungen getestet, ohne daß nennenswerte
Unterschiede in der Schallabsorptionkurve festgestellt
werden konnten. Getestet wurden Polyesterfolien und
Polycarbonatfolien mit einer Dicke von 0,1 mm und
Polyehtylenfolien mit einer Dicke von 0,2 mm. Bei den
Versuchen hat sich ferner gezeigt, daß das Folienmaterial
ohne meßbaren Einfluß auf die Schallabsorption ist. Auch
ist die Spannung der Folie 2 ohne Einfluß auf die
Absorption. Die Folien 2 können straff gespannt sein oder
lose hängen bzw. flexibel bleiben.For the foils themselves there were different ones
Refinements tested without any significant
Differences in the sound absorption curve found
could become. Polyester films and
Polycarbonate films with a thickness of 0.1 mm and
Polyethylene films with a thickness of 0.2 mm. Both
Experiments have also shown that the film material
has no measurable influence on sound absorption. Also
is the tension of the
Die in Fig. 6 wiedergegebene Absorptionskurve beruht auf einem Test mit der in Fig. 5 gezeigten Anordung. Die Folien 2.1, 2.2 wiesen bei diesem Test eine Dicke von 0,105 mm auf. Der Lochdurchmesser für die Microperforation betrug 0,21 mm bei einem Lochabstand von 0,2 mm, entsprechend einem freien Querschnitt von 1 %. Auf der Abszisse ist die Schallfrequenz (in logarithmischem Maßstab) und auf der Ordinate der Absorptionsgrad aufgetragen. The absorption curve shown in FIG. 6 is based on a test with the arrangement shown in Fig. 5. The Foils 2.1, 2.2 had a thickness of 0.105 mm. The hole diameter for the Microperforation was 0.21 mm with a hole spacing of 0.2 mm, corresponding to a free cross section of 1%.
