Description

Die Erfindung bezieht sich auf eine Lärmschutzwand mit einer massiven Wandschale und einer nachgiebigen Vorsatzschale.The invention relates to a noise barrier with a solid wall shell and a flexible front shell.

Lärmschutzwände gibt es in verschiedensten Ausführungs­formen, wobei bisher an Ort und Stelle aufgebaute Mauern und Wälle großer Dicke und Masse die besten Wirkungen zeigen. Um aber die damit verbundenen hohen Herstellungskosten und langen Errichtungszeiten zu verringern, wurde auch schon vorgeschlagen, zwei- oder mehrschalige Lärmschutzwände aus Fertigteilen aufzustellen, und es ist auch bereits bekannt, massive Wandschalen, beispielsweise aus Blech, mit einer nach­giebigen Vorsatzschale aus einer Mineralwollauflage zu kombinieren. Diese Lärmschutzwände können aber weder hinsichtlich ihrer Schutzfunktion, noch hinsicht­lich des Herstellungsaufwandes befriedigen.Noise protection walls are available in a wide variety of designs, with walls and walls of great thickness and mass that have hitherto been built in place having the best effects. However, in order to reduce the associated high manufacturing costs and long erection times, it has also been proposed to install double or multi-layered noise barriers made from prefabricated parts, and it is also known to combine solid wall shells, for example made of sheet metal, with a flexible front shell made from a mineral wool pad . However, these noise barriers can neither satisfy with regard to their protective function, nor with regard to the manufacturing effort.

Gemäß der DE-A 25 39 087 wurde auch schon vorge­schlagen, als Schallabsorber für schalltote Räume Rohrschalen aus Schallschluckmaterial zu verwenden, die in unterschiedlichen Lagen vor einer Wand angeord­net werden. Diese Rohrschalen mit ihren zentimeter­dicken Wandstärken sind vergleichsweise große Einzel­elemente, die sich zur speziellen Auskleidung begrenz­ter Räumlichkeiten eignen mögen, zur Herstellung weit­läufiger Lärmschutzwände entlang von Straßen od.dgl. aber wegen der Umständlichkeit und Kosten ihrer notwen­digen Einzelfertigung und Einzelmontage vollkommen unbrauchbar sind.According to DE-A 25 39 087, it has also already been proposed to use pipe shells made of sound-absorbing material as sound absorbers for anechoic rooms, which are arranged in different positions in front of a wall. These pipe shells with their centimeter-thick walls are comparatively large individual elements, which may be suitable for the special lining of limited spaces, for the production of extensive noise barriers along streets or the like. but are completely unusable because of the complexity and costs of their individual manufacture and assembly.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Lärmschutzwand der eingangs geschilderten Art zu schaffen, die rationell und aufwandsarm errichtet werden kann und sich durch ihren besonders guten Schallschluckeffekt auszeichnet.The invention is therefore based on the object of providing a noise barrier of the type described at the outset which can be erected efficiently and with little effort and is distinguished by its particularly good sound absorption effect.

Die Erfindung löst diese Aufgabe dadurch, daß die vorzugsweise mit Abstand vor der Wandschale verlaufende Vorsatzschale aus Kunststoffhalmbahnen besteht. Die dicht aneinandergereihten Halme dieser Bahnen verur­sachen eine vielfache Brechung der Schallwellen beim Durchdringen der Vorsatzschale und die Nachgiebigkeit und Vibrationsfähigkeit der Halmbahnen führt zu einer entsprechenden Vernichtung der Schallenergie. Zusammen mit der nachgeordneten massiven Wandschale und gege­benenfalls dem zwischen den Schalen verbleibenden Zwischenraum, der zusätzlich mit Dämmaterial gefüllt sein kann, kommt es zu einer hohen Schallschluckwirkung und es werden außerdem unangenehme Schallreflexionen verhindert. Da die massive Wandschale, die vor allem ein hohes Flächengewicht besitzen soll, aus geeigneten Fertigteilen, beispielsweise Beton- oder Asbestzement­platten, Blechtafeln, Kunststoffelementen, sandgefüllte Hohlelemente od.dgl., zusammengesetzt werden kann und sich die Kunststoffhalmbahnen geschickt und ohne großen Aufwand aufziehen lassen, ist ein schnelles, rationelles Errichten der Schallschutzwand möglich. Die Kunststoffhalmbahnen sind darüber hinaus wirt­schaftlich als Massenware zu fertigen und vermitteln durch ihr stroh- oder schilfähnliches Aussehen auch der Schallschutzwand ein natürliches, sich an die Landschaft anpassendes Erscheinungsbild, wozu noch kommt, daß diese Halmbahnen einen guten Untergrund für einen natürlichen Bewuchs ergeben. Wegen der ein­fachen Montage und der guten Wirkung können die Kunst­stoffhalmbahnen auch bestens als schallschluckende Fassaden- oder Dachverkleidungen genützt werden, wobei dann die Gebäudewände und Dachabdeckungen selbst die massive Wandschale bilden.The invention solves this problem in that the facing shell, which preferably runs at a distance from the wall shell, is made of plastic straw sheets. The closely arranged stalks of these webs cause the sound waves to refract multiple times when penetrating the facing shell, and the resilience and vibration ability of the stalk webs leads to a corresponding destruction of the sound energy. Together with the subsequent massive wall shell and, if necessary, the space remaining between the shells, which can also be filled with insulating material, the sound absorption effect is high and unpleasant sound reflections are also prevented. Since the solid wall shell, which is supposed to have a high basis weight, can be assembled from suitable prefabricated parts, for example concrete or asbestos cement slabs, metal sheets, plastic elements, sand-filled hollow elements or the like, and the plastic straw strips can be sent skillfully and without large effort, a quick, efficient erection of the soundproof wall is possible. The plastic stalks are also economically mass-produced and convey a natural, adapting appearance to the soundproofing wall due to their straw or reed-like appearance, which also means that these stalks provide a good surface for natural growth. Because of the simple assembly and the good effect, the plastic straw sheets can also be used as sound-absorbing facade or roof cladding, in which case the building walls and roof covers themselves form the massive wall shell.

Besonders vorteilhaft ist es, wenn die Kunststoffhalm­bahnen an Träger-Drähten, vorzugsweise einem Draht­gitter od.dgl. befestigt sind. Diese Drähte bzw. Gitter bieten den Halmbahnen eine schwingungsfähige elastische Abstützung und verstärken damit die Schutzwirkung. Außerdem können die Kunststoffhalmbahnen über die Drähte oder Gitter einfach und rasch montiert und als Vorsatzschale einer beliebigen Wandschale vor­gehängt werden.It when the plastic straw webs on carrier wires, preferably a wire mesh or the like, is particularly advantageous. are attached. These wires or grids provide the stalks with an elastic support that can vibrate and thus reinforce the protective effect. In addition, the plastic straw strips can be easily and quickly installed over the wires or grids and hung as a facing shell of any wall shell.

Weisen die Kunststoffhalmbahnen eine gelochte Träger­folie für die Kunststoffhalme auf, kann mit der Träger­folie die Festigkeit und Widerstandsfähigkeit der Halmbahnen erhöht und gleichzeitig durch die Per­forierung auch die Schallschutzwirkung verstärkt werden.If the plastic straw sheets have a perforated backing sheet for the plastic straws, the strength and resistance of the straw sheets can be increased with the backing sheet and the soundproofing effect can also be increased by the perforation.

In the drawing, the subject matter of the invention is shown purely schematically in one embodiment, namely show
  • Fig. 1 shows a part of a noise barrier according to the invention in a front view and the
  • 2 and 3 this noise barrier in vertical section and in horizontal section.

Um rationell eine hochwirksame Lärmschutzwand errichten zu können, ist eine zweischalige Wand 1 vorgesehen, die sich aus einer massiven Wandschale 2 und einer nachgiebigen Wandschale 3 zusammensetzt. Die massive Wandschale 2 ist aus vorgefertigten Platten, beispiels­weise Kunststofftafeln 2a, aufgebaut und an Stehern 4 abgestützt. Die nachgiebige Vorsatzschale 3 besteht aus Kunststoffhalmbahnen 3a, die auf einem Drahtgitter 3b aufgezogen und zusammen mit diesem Drahtgitter 3b der Wandschale 2 vorgehängt sind. Drahtgitter 3b und Kunststoffhalmbahnen 3a werden dabei an den Stehern 4 aufgespannt, die auch als Abstandhalter dienen, so daß zwischen Wandschale 2 und Vorsatzschale 3 ein Zwischenraum 5 verbleibt.In order to be able to rationally erect a highly effective noise protection wall, a double-walled wall 1 is provided, which is composed of a solid wall shell 2 and a flexible wall shell 3. The massive wall shell 2 is constructed from prefabricated panels, for example plastic panels 2a, and is supported on uprights 4. The resilient facing shell 3 consists of plastic straw sheets 3a, which are mounted on a wire mesh 3b and are hung together with this wire mesh 3b of the wall shell 2. Wire mesh 3b and plastic straw sheets 3a are stretched on the uprights 4, which also serve as spacers, so that a space 5 remains between the wall shell 2 and the facing shell 3.

Die Kunststoffhalmbahnen 3a sind Bahnen aus dicht nebeneinandergereihten schilf- oder strohähnlichen Kunststoffhalmen, die miteinander vernäht oder ver­schweißt und vorzugsweise mit einer gegebenenfalls gelochten Trägerfolie verbunden sind. Die Bahnen können kontinuierlich hergestellt werden und lassen sich, in gut verlegbare Stücke abgelängt, ohne Schwierig­keiten am Drahtgitter 3b befestigen und an den Stehern 4 montieren. Es entsteht eine schwingungsfähige Vor­satzschale 3, die wesentlich zum Brechen der Schall­wellen und zum Vernichten der Schallenergie beiträgt, so daß es zusammen mit der massiven Wandschale 2 und dem Zwischenraum 5, der gegebenenfalls ein Schall­schluckmaterial wie Schaumstoff, Mineralwolle od.dgl. aufnimmt, insgesamt zu einem hochwirksamen Schallschutz kommt. Dabei bleibt der Bau- und Herstellungsaufwand gering und durch den schilf- oder strohähnlichen Ein­durch der Kunststoffhalmbahnen zeichnet sich die er­richtete Lärmschutzwand 1 vor allem auch durch ihr gefälliges, an die Landschaft angpaßbares Äußeres aus.The plastic straw sheets 3 a are sheets of reed or straw-like plastic straws which are tightly lined up, which are sewn or welded to one another and are preferably connected to an optionally perforated carrier film. The sheets can be produced continuously and, cut into pieces that can be easily laid, can be easily attached to the wire mesh 3b and mounted on the uprights 4. There is a vibratory facing 3, which contributes significantly to the breaking of the sound waves and the destruction of the sound energy, so that it together with the solid wall shell 2 and the space 5, which may be a sound absorbing material such as foam, mineral wool or the like. records, overall comes to a highly effective sound insulation. The construction and manufacturing costs remain low and the built-in noise barrier 1 is characterized above all by its pleasant exterior, which can be adapted to the landscape, due to the reed- or straw-like indentation of the plastic stalks.
