Abstract
Description
Lärmschutzwandelemente, wie sie neben Straßen oder Bahnstrecken zu sehen sind, bestehen aus Tragbeton mit lärmdämmender Vorsatzschale oder aus einem Metallkasten (meistens Aluminium) mit lärmdämmender Füllung, in dessen Außenhaut Löcher für den Schalleintritt vorhanden sind. Die Außenhaut solcher metallischer Lärmschutzwandelemente ist aus zwei Halbschalen zusammengesetzt.
Lärmschutzwandelemente mit metallischer Außenhaut, besonders solche aus Leichtmetall wie Aluminium, sind deutlich leichter und damit auch besser zu installieren (auch manuell handhabbar) als ihre Gegenstücke aus Beton. Sie sind jedoch deutlich teurer und waren bislang auch nicht so beständig gegen Witterung sowie gegen Vögel und Insekten, die dem im Inneren befindlichen Lärmschutzmaterial zusetzen.Noise protection wall elements, as can be seen next to roads or railway lines, consist of load-bearing concrete with noise-damping facing shell or of a metal box (mostly aluminum) with noise-damping filling, in the outer skin holes for the sound entry are available. The outer skin of such metallic noise barrier elements is composed of two half-shells.
Noise protection wall elements with a metallic outer skin, especially those made of light metal such as aluminum, are significantly lighter and thus also easier to install (also manageable) than their counterparts made of concrete. However, they are much more expensive and have so far not been so resistant to weather as well as to birds and insects that clog the inside noise control material.
Aufgabe der Erfindung ist es, eine Konstruktion für ein Lärmschutzwandelement mit metallischer Außenhaut, bevorzugt aus einem Leichtmetall wie Aluminium, anzugeben, das beständig und kostengünstig ist.The object of the invention is to provide a construction for a noise barrier wall element with metallic outer skin, preferably made of a light metal such as aluminum, which is durable and inexpensive.
Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Die Erfindung sieht hierzu vor, die gesamte Außenhaut nicht aus zwei Halbschalen zusammenzusetzen, sondern ein günstig zu fertigendes, nach vier Seiten geschlossenes, einstückiges Strangpreßprofil (1) zu verwenden.The object is solved by the features specified in the characterizing part of claim 1. The invention provides for this purpose, not to assemble the entire outer skin of two half-shells, but to use a low-to-manufacture, four-sided closed, one-piece extruded profile (1).
Dieses Strangpreßprofil (1) weist an der dem Lärm zugewandten Seite (3) Ausnehmungen/Löcher auf, die mehr als 25% dieser Fläche ausmachen. Die Ausnehmungen/Löcher können viele mögliche Formen aufweisen, z.B. rund, schlitz- oder bienenwabenförmig (sechseckig).This extruded profile (1) has on the side facing the noise (3) recesses / holes, which make up more than 25% of this area. The recesses / holes may have many possible shapes, e.g. round, slotted or honeycomb-shaped (hexagonal).
Im Inneren des Kastens (1, 3, 4) befindet sich, parallel und mit etwas Abstand zur lärmzugewandten Außenwand (3), schallabsorbierendes Material (2). Der Abstand zur Metallaußenhaut (3, 4) ermöglicht die Ausbildung eines Resonatorraumes zwischen schallabsorbierendem Material (2) und Außenhaut (3, 4) und verhindert gleichzeitig, daß Vögel mit ihren Schnäbeln schallabsorbierendes Material durch die Ausnehmungen/Löcher herauspicken können.Inside the box (1, 3, 4) is located, parallel and slightly spaced from the noise-facing outer wall (3), sound-absorbing material (2). Of the Distance to the metal outer skin (3, 4) allows the formation of a resonator space between sound absorbing material (2) and outer skin (3, 4) and prevents at the same time that birds with their beaks can pick out sound absorbing material through the recesses / holes.
Das schallabsorbierende Material (2) ist bevorzugt formbeständig, so das es auch bei Nässe nicht in sich zusammensackt (Lärmschutzplatten).The sound-absorbing material (2) is preferably dimensionally stable, so that it does not collapse in wet conditions (noise protection plates).
Beim schallabsorbierenden Material (2) kann es sich zum Beispiel um Mineralwolle handeln, die durch entsprechende Ausrüstung (textile Einlagen oder Verharzung/Mineralisierung auch bei Nässe formstabil gehalten wird (Mineralwollplatten).The sound-absorbing material (2) may, for example, be mineral wool, which is kept dimensionally stable by means of appropriate equipment (textile deposits or resinification / mineralization even in the wet (mineral wool boards).
Das Lärmschutzmaterial (2) wird seitlich in das Strangpreßprofil (1) eingeschoben, bevorzugt gehaltert und geführt durch Haltebacken (7), die ebenfalls schon Teil des einstückigen Strangpreßprofils (1) sind.The noise protection material (2) is laterally inserted into the extruded profile (1), preferably supported and guided by holding jaws (7), which are also already part of the one-piece extruded section (1).
Nach dem Einführen des Lärmschutzmaterials (2) können die seitlichen Öffnungen vorne und hinten mit Kappen oder Stopfen verschlossen werden.After inserting the noise protection material (2), the side openings can be closed at the front and back with caps or plugs.
Eine Lärmschutzwand wird aus den erfindungsgemäßen Lärmschutzwandelementen auf übliche Weise zusammengebaut. Hierzu werden die erfindungsgemäßen Lärmschutzwandelemente bis zur gewünschten Höhe der Lärmschutzwand übereinander gestapelt.A noise barrier is assembled from the noise barrier elements according to the invention in the usual way. For this purpose, the noise protection wall elements according to the invention are stacked one above the other to the desired height of the noise protection wall.
Zum besseren Verbund der Lärmschutzwandelemente untereinander weisen diese bevorzugt an ihrer Ober- und Unterseite ein Nut-/Federprofil (5, 6) auf. Dadurch werden die einzelnen Elemente zwischen den Lärmschutzwandpfosten zu einer Gesamtwand verbunden und führen keine eigenständigen Bewegungen gegeneinander aus.To better composite the noise barrier elements with each other, these preferably have on their top and bottom a tongue / groove profile (5, 6). As a result, the individual elements between the noise protection wall posts are connected to a total wall and perform no independent movements against each other.
Um das Ablaufen von Regenwasser zu ermöglichen, weisen die Lärmschutzwandelemente vorzugsweise an ihren tiefsten Punkten, an denen sich ansonsten Wasser stauen könnte, Öffnungen auf.In order to allow drainage of rainwater, the noise barrier elements preferably have openings at their lowest points where water could otherwise accumulate.
Die Figuren zeigen eine mögliche Ausführung der Erfindung. Das beschriebene Lärmschutzwandelement weist in diesem Fall an seiner lärmzugewandten Seite (3) Ausnehmungen/Löcher auf und ist an der lärmabgewandten Seite (4) geschlossen. Eine Mineralwollplatte (2) erstreckt sich im Inneren des Strangpreßprofils (1) von einer unteren Nut (5) bis zu einer oberen Feder (6). Im gezeigten Beispiel weist die Mineralwollplatte (2) auch zur geschlossenen Seite (4) des Lärmschutzwandelementes hin einen Abstand auf. Dieser kann aber auch entfallen.The figures show a possible embodiment of the invention. The described noise protection wall element has in this case on its noise-facing side (3) recesses / holes and is closed on the side facing away from noise (4). A mineral wool plate (2) extends inside the extruded section (1) from a lower groove (5) to an upper spring (6). In the example shown, the mineral wool plate (2) also at the closed side (4) of the noise protection wall element towards a distance. This can also be omitted.
Fig. 1 zeigt einen Querschnitt durch ein erfindungsgemäßes Lärmschutzwandelement mit Nut (5) und Feder (6) zum Übereinanderstapeln. Die Lärmschutzplatte (2) ist durch Haltebacken (7) mit Abstand von den Außenwandungen (3, 4) gehaltert. Die Haltebacken (7) sind Teil des Strangpreßprofils (1).Fig. 1 shows a cross section through an inventive noise barrier wall element with groove (5) and spring (6) for stacking. The noise protection plate (2) is held by holding jaws (7) at a distance from the outer walls (3, 4). The holding jaws (7) are part of the extruded profile (1).
Ein solches Lärmschutzwandelement weist typischerweise eine Länge auf, die dem Abstand der Pfosten der Lärmschutzwand entspricht (mehrere Meter), eine Höhe von ungefähr 25 cm und eine Dicke von ungefähr 12 cm. Abweichungen um den Faktor 2 sind üblich.Such a noise barrier member typically has a length corresponding to the distance of the posts of the noise barrier (several meters), a height of about 25 cm and a thickness of about 12 cm. Deviations by a factor of 2 are common.
Wenn die Versteifungen (9) des Strangpreßprofiles (1) auf der Seite der gelochten Metallfläche (3) entfallen oder schräg nach vorne hin abfallen, verbessert sich das Absorbtionsvermögen des Lärmschutzwandelements etwas, weil sich dadurch die Schalleintrittsfläche des Lärmschutzwandelements vergrößert.If the stiffeners (9) of the extruded section (1) on the side of the perforated metal surface (3) omitted or sloping obliquely forward, the Absorbtionsvermögen the noise protection wall element improves slightly because it increases the sound incidence surface of the noise barrier element.
Fig. 2 zeigt im Querschnitt ein Lärmschutzelement größerer Höhe, das zur Erhöhung der Steifigkeit einen Zwischenboden (8) aufweist. Durch Einfügen weiterer Zwischenböden (8) kann die Höhe der Lärmschutzwandelemente weiter gesteigert werden.Fig. 2 shows in cross section a noise protection element of greater height, which has an intermediate bottom (8) to increase the rigidity. By inserting additional shelves (8), the height of the noise barrier elements can be further increased.
