Description

Die Erfindung bezieht sich auf eine Schallschutzvorrichtung für Schallschutzwände an Straßen oder anderen Lärmquellen, wie insbesondere für Fenster und Türen an Gebäuden.The invention relates to a soundproofing device for soundproof walls on streets or other noise sources, such as in particular for windows and doors on buildings.

Man kennt nach der DE-OS 29 16 478 solche Schallschutzvorrichtungen bestehend aus mindestens zwei Reihen von Deckplatten, insbesondere -Leisten, welche im Abstand hintereinander angeordnet sind und jeweils zueinander versetzte Öffnungen aufweisen. Nach der DE-OS 14 34 235 ist es ferner bekannt bei Doppelrolläden gewölbte Rolladenleisten versetzt hintereinander anzuordnen, um so eine Abdeckung der Rolladenschlitze und damit eine gewisse Lärmdämmung zu erreichen, jedoch ohne einen Luftdruchlaß anzustreben.Such soundproofing devices are known from DE-OS 29 16 478 consisting of at least two rows of cover plates, in particular strips, which are arranged at a distance from one another and each have openings offset from one another. According to DE-OS 14 34 235 it is also known to arrange curved roller shutter slats staggered one behind the other in double roller shutters in order to achieve a covering of the roller shutter slits and thus a certain level of noise insulation, but without striving for air passage.

Aufgabe der Erfindung ist es nun ausgehend von der ersten Anordnung eine optimalere Lärmdämmung bei genügend Lüftungseigenschaften zu erreichen und überdies auch eine Lichtdurchlässigkeit zu ermöglichen, wobei der Schall durch die Eintrittsöffnungen zurückreflektiert werden soll.Based on the first arrangement, the object of the invention is now to achieve more optimal noise insulation with sufficient ventilation properties and, moreover, to enable light transmission, the sound being intended to be reflected back through the inlet openings.

Die Schallschutzvorrichtung nach der Erfindung bestehend aus mindestens zwei Reihen von Deckplatten, insbesondere -Leisten, welche im Abstand hintereinander angeordnet sind und jeweils zueinander versetzte Öffnungen aufweisen, kennzeichnet sich dadurch, daß die Öffnungen an Hinterschneidungen ihrer Öffnungsränder jeweils von im Abstand gehaltenen auf die Öffnungen zentrierte Wölbungsteile überdeckt sind, wobei der Mittelpunkt - Brennpunkt - zumindestens der hinterden ersten Öffnungen liegenden Wölbungsteile insbes. in oder über der ersten Öffnungsmitte liegt. Hierdurch wird eine weitgehende Schallreflektrierung erreicht.The soundproofing device according to the invention consisting of at least two rows of cover plates, ins Special strips, which are arranged at a distance from one another and each have openings offset from one another, are characterized in that the openings at undercuts of their opening edges are each covered by spaced-apart curved parts centered on the openings, the center - focal point - at least the rear first curvature parts lying in particular in or above the first center of the opening. As a result, extensive sound reflection is achieved.

Im einzelnen können auch die Mittelpunkte - Brennpunkte - aller aufeinanderfolgenden Wölbungsteile, welche Kreis-oder Ellipsenform aufweisen, insbes. in oder über der jeweiligen Öffnungsmitte liegen.In particular, the center points - focal points - of all successive curvature parts, which have a circular or elliptical shape, in particular can be located in or above the respective center of the opening.

Hierbei finden vorzugsweise gestaffelt hintereinandergesetzte Deckleisten mit im Querschnitt Doppel-T-Form Verwendung bei entsprechend angeordneten Kanalwölbungen, welche derart ineinandergreifen, daß eine gegenseitige Schlitzabdeckung mit zwischenliegenden Öffnungsschlitzen entsteht. Auch können die Öffnungen als Lochungen ausgebildet sein, zu denen kreisbogenförmige Teller- bzw. Ringkanalwölbungen mit zwischenliegenden Öffnungen folgend angeordnet sind.In this case, staggered cover strips with a double-T shape in cross-section are preferably used with appropriately arranged channel curvatures which interlock in such a way that a mutual slot cover with intervening opening slots is created. The openings can also be designed as perforations, followed by circular arc-shaped plate or ring channel arches with intermediate openings.

Schließlich können zur Bildung von Rolläden bei Verwendung von Deckleisten dieselben mittels Zapfen oder Rollen in seitliche Rolladenführungen greifen, welche am Einzugsende gegeneinander und versetzt abgewinkelt sind. oder aber die Deckleisten sind hängend nach Art von Vorhängen vorziehbar.Finally, when using cover strips, the same can be formed by means of pins or to form roller shutters Grip the rollers in the lateral roller shutter guides, which are angled and offset at the feed end. or the cover strips can be pulled down like curtains.
