Description

Die Erfindung betrifft eine Lärmschutzwand, aufweisend wenigstens ein drahtgitterartiges Wandkörper-Element, das wenigstens teilweise mit einem schallabsorbierenden, begrünungsfähigen und biologisch abbaubaren Füllmaterial gefüllt ist und aus zwei parallel zueinander angeordneten und in einem Abstand voneinander aufgestellten Drahtgitter-Zaunelementen besteht.The invention relates to a noise barrier, comprising at least one wire-grid-like wall body element which is at least partially filled with a sound-absorbing, begrünungsfähigen and biodegradable filling material and consists of two mutually parallel and spaced apart wire mesh fence elements.

Eine solche Lärmschutzwand ist aus DE 89 11 878 U1 bekannt. Sie wird aus Bauelementen hergestellt, die im Wesentlichen aus beabstandeten Stützprofilen bestehen, die im Boden verankert werden. Zwischen den Stützprofilen können Wandflächen angeordnet werden, die gitterförmig oder vollwandig sind. Die zusammengesetzten Bauelemente ergeben Zwischenräume, die mit Erdreich ausgefüllt und begrünt werden können.Such a noise barrier is off DE 89 11 878 U1 known. It is made of components consisting essentially of spaced support profiles that are anchored in the ground. Between the support profiles wall surfaces can be arranged, which are lattice-shaped or full-walled. The composite components result in spaces that can be filled with soil and landscaped.

Diese Art der Begrünung von Lärmschutzwänden erfordert viel Nacharbeit nach dem Aufstellen der Stützprofile, wobei nicht ausgeschlossen werden kann, dass zumindest zu Anfang des Bewachsens das Erdreich ausgewaschen und fortgespült wird.This type of greening of noise barriers requires a lot of rework after setting up the support profiles, which can not be ruled out that at least at the beginning of the growth, the soil is washed out and washed away.

Eine andere Lärmschutzwand ist aus der DE 35 35 343 C2 bekannt. Bei dieser bestehen die einzelnen, etwa trapezförmigen Wandkörper-Elemente jeweils aus U-förmigen Rahmenteilen, deren U-Schenkel an einem starren Fußgestell angebracht sind. Mit dem Fußgestell ist eine engmaschige, metallene Bodenmatte gegen das Herausfallen des Füllmaterials beim Transport verbunden. Das Wandkörper-Element zeichnet sich durch einen komplizierten Aufbau und ein erhebliches Gesamtgewicht aus und erfordert eine entsprechend tragfähige Hebeeinrichtung. Dies erhöht die Transport-, Lager- und Montagekosten.Another noise barrier is from the DE 35 35 343 C2 known. In this case, there are the individual, about trapezoidal Wall body elements each of U-shaped frame parts, the U-legs are mounted on a rigid pedestal. With the pedestal a closely meshed metal floor mat is connected against falling out of the filling material during transport. The wall body element is characterized by a complicated structure and a considerable overall weight and requires a correspondingly viable lifting device. This increases the transport, storage and assembly costs.

Es stellt sich die Aufgabe, die Begrünung der Lärmschutzwände durch einfache, durch Witterungseinflüsse praktisch nicht zu beschädigende Maßnahmen einzuleiten, wobei der Aufbau der Lärmschutzwand und das Begrünen derselben montagefreundlich und ohne großen Aufwand an Hebeeinrichtungen durchgeführt werden können.It has as its object to initiate the greening of the noise barriers by simple, by weather conditions practically not to be damaged measures, the structure of the noise barrier and the greening of the same easy to install and can be performed without much effort on lifting equipment.

Diese Aufgabe wird bei einer Lärmschutzwand der eingangs genannten Art dadurch gelöst, dass das Füllmaterial aus mehreren Lagen einer gewebe- oder vliesartigen, flüssigkeitssaugfähigen, aus nachwachsenden Rohstoffen hergestellten Matte besteht, die aufeinander gelegt oder zusammengefaltet sind, wobei die Matte von einer biologisch abbaubaren, verrottbaren, perforierten Folie auf Stärkebasis oder von einem verrottbaren Gewebe umhüllt ist.
Als Füllmaterialien kommen unterschiedliche, vorzugsweise biologisch abbaubare Stoffe in Frage, beispielsweise Kokosfaser-, Leinen-, Hanf- oder Strohmatten, die sich aufeinanderlegen oder zusammenfalten lassen. Die einzelnen Matten oder das gesamte sich im Raum befindende Füllmaterial können umhüllt sein, beispielsweise von einem Jutegewebe oder von einer biologisch abbaubaren, verrottbaren, perforierten Folie auf Stärkebasis.This object is achieved in a noise barrier of the type mentioned above in that the filler consists of several layers of a fabric or fleece-like, liquid-absorbent, made of renewable raw mat, which are placed on each other or folded, the mat of a biodegradable, decomposable perforated starch-based film or wrapped in a decomposable tissue.
As filling materials are different, preferably biodegradable substances in question, for example, coconut fiber, linen, hemp or straw mats that can be folded or folded. The individual mats or all of the filling material in the room may be wrapped, for example, a jute fabric or a biodegradable, degradable, perforated starch-based film.

In den besagten Raum kann auch ein bereits mit Düngemittel angereichertes Füllmaterial eingelegt sein, das nach Befeuchtung und Besamung durchwurzelt wird und nach relativ kurzer Zeit einen begrünten Lärmschutzwall ergibt.In the said space may also be an already enriched with fertilizer filler inserted, which is rooted by moistening and insemination and results in a green noise barrier after a relatively short time.

Zum Aufbau der Wandkörper-Elemente und damit der ganzen Lärmschutzwand können an sich bekannte Drahtgitter-Zaunelemente verwendet werden.For the construction of the wall body elements and thus the entire noise barrier can be used per se known wire mesh fence elements.

Der Begriff "Drahtgitter-Zaunelement" bezieht sich auf marktübliche Zaunelemente, die aus Draht, Stäben oder Profilen gefertigt sind. Die Zaunelemente können auch aus einem kunststoffummantelten und entsprechend verstärktem Maschendrahtgeflecht oder aus einem dekorativen Drahtgitter gefertigt sein.The term "wire mesh fence element" refers to commercially available fence elements made of wire, rods or profiles. The fence elements can also be made of a plastic-coated and correspondingly reinforced wire mesh or of a decorative wire mesh.

Die Drahtgitter-Zaunelemente können fest oder abnehmbar mit den Zaunpfosten verbunden sein. Bevorzugt wird eine einfache Aufhängung und/oder Verschraubung.The wire mesh fence elements may be fixed or detachable connected to the fence posts. Preferred is a simple suspension and / or screw.

Als Material zur Herstellung von Drahtgitter-Zaunelementen eignen sich unterschiedliche Metalle oder deren Legierungen, insbesondere verzinkter Stahl. Es ist aber auch möglich, die Zaunelemente aus schlagfestem und witterungsbeständigem Kunststoff herzustellen.As a material for the production of wire mesh fence elements are different metals or their alloys, in particular galvanized steel. But it is also possible to produce the fence elements made of impact-resistant and weather-resistant plastic.

Die Zaunelemente sind in ihrer bevorzugten Ausführungsform rechteckig, d.h. sie weisen ein rechteckiges Zaunfeld auf. Sie können aber nach Bedarf in Trapezform oder in Form eines schrägen Parallelogramms gefertigt sein. Die oberen, freien Längsstäbe der Drahtgitter-Zaunelemente können geradlinig oder gewölbt sein.The fence elements are rectangular in their preferred embodiment, ie they have a rectangular fence panel. But they can be made as required in trapezoidal shape or in the form of an oblique parallelogram. The upper, free longitudinal bars of the wire mesh fence elements may be rectilinear or curved.

In den Figuren 2 bis 4 ist eine Lärmschutzwand 100 schematisch dargestellt, die sich aus mehreren geradlinig hintereinander (vgl. Fig. 4) aufgestellten Wandkörper-Elementen 1.1, 1.2,....1.n zusammensetzt.In the FIGS. 2 to 4 is a noise barrier 100 shown schematically, which consists of several straight behind each other (see. Fig. 4 ) erected wall body elements 1.1, 1.2, .... 1.n composed.

Das Wandkörper-Element 1.1...1.n ist detailliert in Fig. 1 gezeigt. Es besteht aus zwei parallel zueinander angeordneten und in einem Abstand A = 40 cm voneinander aufgestellten Drahtgitter-Zaunelementen 10.1, 10.2 aus verzinktem Stahl, deren beide Enden 4.1, 4.2 jeweils an einem bereits im Erdreich 5 einbetonierten Zaunpfosten 2.1, 2.2; 2.3, 2.4 abnehmbar befestigt sind. So entsteht ein Raum 8, definiert durch den Abstand A, eine Höhe H und die jeweilige Länge des Drahtgitter-Zaunelementes bzw. der Drahtgitter-Zaunelemente. Die Enden 4.1, 4.2 der Drahtgitter-Zaunelemente 10.1, 10.2 weisen Flacheisen 9 auf, die mit entsprechenden Bohrungen 11 für die Verschraubung mit den Zaunpfosten versehen sind.The wall body element 1.1 ... 1.n is detailed in Fig. 1 shown. It consists of two wire mesh fence elements 10.1, 10.2 of galvanized steel arranged parallel to one another and spaced at a distance A = 40 cm from each other, both ends 4.1, 4.2 of which are each fastened to a fence post 2.1, 2.2; 2.3, 2.4 are detachably attached. This creates a space 8, defined by the distance A, a height H and the respective length of the wire mesh fence element or the wire mesh fence elements. The ends 4.1, 4.2 of the wire mesh fence elements 10.1, 10.2 have flat iron 9, which are provided with corresponding holes 11 for screwing with the fence posts.

Die Zaunpfosten 2.1, 2.2; 2.3, 2.4 sind beispielsweise Viereckrohre 80 x 40 mm, die in vorbestimmten Abständen voneinander tief in die frostbeständigen, einzelnen Fundamente 7 gesetzt worden sind.The fence posts 2.1, 2.2; 2.3, 2.4 are, for example, square tubes 80 x 40 mm, which have been set at predetermined intervals from each other deep into the frost-resistant, individual foundations 7.

Ferner zeigt die Fig. 1 ein in den Raum 8 plaziertes, schallabsorbierendes Füllmaterial 6 aus nachwachsenden Rohrstoffen. Das Füllmaterial 6 besteht im vorliegenden Fall aus mehreren Lagen 16.1....16.n einer Kokosfasermatte 16, die mit einer granulatartigen Mischung aus Torf und Düngemittel durchsetzt ist.Furthermore, the shows Fig. 1 a placed in the space 8, sound-absorbing filler 6 made of renewable materials. The filler 6 is made in the present case several layers 16.1 .... 16.n of a coconut fiber mat 16, which is interspersed with a granular mixture of peat and fertilizer.

Aus der Fig. 3 ist ersichtlich, daß die zwei ein Wandkörper-Element bildenden Drahtgitter-Zaunelemente unterschiedliche Höhen aufweisen, so daß die Höhe der Füllmaterial-Packung den oberen Rand des niedrigeren Zaunelementes nicht überschreiten kann. Eine solche Ausführungsform der Lärmschutzwand eignet sich insbesondere zum Einzäunen von Schulhöfen oder Sportplätzen innerhalb von Siedlungen.From the Fig. 3 It can be seen that the two wire mesh fencing elements forming a wall member element have different heights, so that the height of the filler packing can not exceed the upper edge of the lower fence element. Such an embodiment of the noise barrier is particularly suitable for fencing schoolyards or sports grounds within settlements.

Die Lärmschutzwand gemäß der Erfindung kann waagerecht auf einem ebenen Boden oder am Hang treppenartig aufgestellt sein, wie in Fig. 5 dargestellt.The noise barrier according to the invention may be placed horizontally on a flat floor or on a slope staircase, as in Fig. 5 shown.

Zum Erstellen der Lärmschutzwand 100 gemäß Fig.4 werden zuerst die Zaunpfosten 2.1, 2.2,...2.n im Erdreich in vorbestimmten Abständen voneinander einbetoniert. Danach werden die vorgefertigten Zaunfelder an den entlang einer Linie L1 (vgl. Fig. 4) verlaufenden Zaunpfosten angeschraubt und die Matten 16 des Füllmaterials bis zur gewünschten Höhe eingeschichtet. Durch das Anschrauben und Fixieren der Zaunfelder auf der gegenüberliegenden Seite (Linie L2) werden die Matten 16 komprimiert. Die Stabilität der Lärmschutzwand verbessern die in den Figuren 2 und 3 gezeigten Querstreben 3, die die sich gegenüberliegenden Zaunfelder miteinander verbinden. Zur Begrünung der Lärmschutzwall wird das Füllmaterial befeuchtet und besamt.To create the noise barrier 100 according to Figure 4 first the fence posts 2.1, 2.2, ... 2.n are embedded in the ground at predetermined distances from each other. Thereafter, the prefabricated fence panels at along a line L 1 (see. Fig. 4 ) running fence post screwed and the mats 16 of the filling material layered to the desired height. By screwing and fixing the fence panels on the opposite side (line L 2 ), the mats 16 are compressed. The stability of the noise barrier improve in the FIGS. 2 and 3 shown cross struts 3, which connect the opposing fence panels together. To green the noise barrier, the filling material is moistened and inseminated.
