Definitions
- the invention relates to an element for soundproof walls and for cladding of concrete and rock walls according to the preamble of claim 1.
- protective walls are used, for. B. of the type described in DE-OS 35 35 343. They consist of essentially U-shaped frames arranged one behind the other at intervals, which are connected to one another, for example, by means of longitudinal beams, tensioning cables or the like. Relatively close-meshed mats can be applied to the front and side surfaces of the U-shaped frames in order to keep soil material within the protective wall. Rigid frame-forming pedestals are provided for transport, so that a prefabricated protective wall can be loaded onto a truck and brought to the place of use despite the considerable weight by means of a lifting device.
- DE-GM 78 33 360 describes a noise barrier for traffic routes and squares, which has a number of polygonal, elongated frames which are arranged at intervals from one another.
- a scaffold constructed using spacers for the frames has, at least on the sides, walls which are suitable for plant growth and are permeable to water.
- the frame, spacers and walls are made of rotting-resistant material, so that the limited space can be filled with soil and plants used can penetrate the walls.
- this protective wall is somewhat simpler in comparison with the aforementioned construction and therefore cheaper to manufacture, the construction of the individual parts remains complex. Neither the assembly nor the disassembly of this noise barrier can be done in a modular manner. The dimensions are also relatively large and the transport costs are correspondingly high.
- protective walls or cladding should be able to be assembled and disassembled in a modular manner to protect the road or Favorably influence the landscape and living and living conditions.

Abstract
Description
Die Erfindung betrifft eine Element für Schallschutzwände sowie für Verkleidungen von Beton- und Felswänden gemäß dem Oberbegriff von Anspruch 1.The invention relates to an element for soundproof walls and for cladding of concrete and rock walls according to the preamble of
Zur Bekämpfung von Lärm auf Straßen oder Plätzen sowie für deren gärtnerische Gestaltung benutzt man Schutzwände z. B. des in der DE-OS 35 35 343 beschriebenen Typs. Sie bestehen aus in Abständen hintereinander angeordneten, im wesentlichen U-förmigen Rahmen, die beispielsweise über Längstraversen, Spannseile oder dergleichen miteinander verbunden sind. Auf den Stirn- und Seitenflächen der U-förmigen Rahmen können relativ engmaschige Matten aufgebracht werden, um Erdmaterial innerhalb der Schutzwand zu halten. Zum Transport sind starre rahmenbildende Fußgestelle vorgesehen, so daß eine vorgefertigte Schutzwand trotz beachtlichen Gewichts mittels eines Hebezeugs auf einen Lastkraftwagen verladen und zum Einsatzort gebracht werden kann.To combat noise on streets or squares and for their landscaping, protective walls are used, for. B. of the type described in DE-OS 35 35 343. They consist of essentially U-shaped frames arranged one behind the other at intervals, which are connected to one another, for example, by means of longitudinal beams, tensioning cables or the like. Relatively close-meshed mats can be applied to the front and side surfaces of the U-shaped frames in order to keep soil material within the protective wall. Rigid frame-forming pedestals are provided for transport, so that a prefabricated protective wall can be loaded onto a truck and brought to the place of use despite the considerable weight by means of a lifting device.
Die Herstellung und Erichtung solch stabiler Schutzwände erfordert viel Zeit und einen entsprechend hohen Kostenaufwand. Diese gilt auch für die Fertigung und Montage der einzelnen Bauteile, wobei an den Außenseiten eines Gerüstes zunächst Baustahlmatten und gegebenenfalls an der Innenseite der Schutzwand zusätzliche Matten etwa aus Kokosfasern in recht umständlicher Weise anzubringen sind. Nicht selten treten derartige Schutzwände optisch stark in Erscheinung, wodurch das von allgemeiner Industrialisierung ohnehin bereits gestörte Straßen- bzw. Landschaftsbild noch ungünstiger beeinflußt wird.The manufacture and erection of such stable protective walls takes a lot of time and a correspondingly high cost. This also applies to the manufacture and assembly of the individual components, with structural steel mats first being attached to the outside of a scaffold and additional mats made from coconut fibers, for example, made from coconut fibers, in a rather cumbersome manner. It is not uncommon for such protective walls to have a strong visual appearance, as a result of which the street or landscape appearance, which is already disturbed by general industrialization, is influenced even more adversely.
Im DE-GM 78 33 360 ist eine Lärmschutzwand für Verkehrswege und Plätze beschrieben, die eine Anzahl von vieleckigen, länglichen Rahmen aufweist, welche in Abständen zueinander angeordnet werden. Ein mittels Abstandshaltern für die Rahmen aufgebautes Gerüst hat zumindest seitlich Wände, die für Pflanzenbewuchs geeignet und wasserdurchlässig sind. Rahmen, Abstandshalter und Wände bestehen aus gegen Verrottung resistentem Material, so daß der dadurch begrenzte Raum mit Erdreich verfüllbar ist und eingesetzte Pflanzen in die Wände eindringen können. Diese Schutzwand ist zwar im Vergleich mit der vorgenannten Konstruktion etwas einfacher und damit in der Herstellung billiger, doch bleibt der Aufbau der Einzelteile aufwendig. Weder die Montage noch die Demontage dieser Lärmschutzwand kann baukastenartig erfolgen. Auch sind die Abmessungen relativ groß und die Transportkosten entsprechend hoch.DE-GM 78 33 360 describes a noise barrier for traffic routes and squares, which has a number of polygonal, elongated frames which are arranged at intervals from one another. A scaffold constructed using spacers for the frames has, at least on the sides, walls which are suitable for plant growth and are permeable to water. The frame, spacers and walls are made of rotting-resistant material, so that the limited space can be filled with soil and plants used can penetrate the walls. Although this protective wall is somewhat simpler in comparison with the aforementioned construction and therefore cheaper to manufacture, the construction of the individual parts remains complex. Neither the assembly nor the disassembly of this noise barrier can be done in a modular manner. The dimensions are also relatively large and the transport costs are correspondingly high.
Es ist ferner seit längerem üblich, steile Böschungen, Fels-und Betonwände mit Drahtnetzen zu sichern und anschließend zu begrünen, etwa nach dem Hydrosaat-Verfahren oder durch konventionelle Bepflanzung. Letztere kann z. B. aus Gräsern, Büschen, Gehölzen und dergleichen bestehen, denen die Drahtnetze einen Halt bieten. Man ist außerdem bestrebt, den Bereich unterhalb der betreffenden Böschung vor Steinschlag infolge von Erosion zu schützen; diese selbst kann aber herkömmlich nicht nennenswert eingedämmt werden. Meist sind auch Bodenverhältnisse und Standorte wenig vorteilhaft für eine gute, geschlossene Entwicklung der Vegetation.It has also been common practice for some time now to secure steep slopes, rock and concrete walls with wire nets and then to green them, for example using the hydrosowing method or by conventional planting. The latter can e.g. B. consist of grasses, bushes, woody plants and the like, to which the wire nets offer support. Efforts are also being made to protect the area below the slope in question from falling rocks due to erosion; however, this itself cannot be contained significantly. Soil conditions and locations are usually not very advantageous for a good, closed development of the vegetation.
Est ist ein wichtiges Ziel der Erfindung, für Schallschutzwände sowie für Verkleidungen von Beton- und Felswänden ein verbessertes Element zu schaffen, mittels dessen abgegrenzte steile Außenflächen in vielfacher Gestaltung rasch und zuverlässig herstellbar sind. An Ort und Stelle sollen sich damit baukastenartig Schutzwände bzw. Verkleidungen in einfacher Weise auf- und abbauen lassen, die das Straßen- bzw. Landschaftsbild sowie die Lebens- und Wohnbedingungen günstig beeinflussen. Ferner bezweckt die Erfindung die Schaffung eines Elements zum wirksamen Erosionsschutz von übersteilen Böschungen, Betonwänden und dergleichen, die auch dauerhaft begrünbar sein sollen.It is an important aim of the invention to create an improved element for soundproofing walls and for cladding of concrete and rock walls, by means of which delimited steep outer surfaces can be produced quickly and reliably in a variety of designs. On site, protective walls or cladding should be able to be assembled and disassembled in a modular manner to protect the road or Favorably influence the landscape and living and living conditions. Furthermore, the invention aims to provide an element for effective erosion protection of over-steep slopes, concrete walls and the like, which should also be able to be planted permanently.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Ausgestaltungen der Erfindung ergeben sich aus den Ansprüchen 2 bis 20.This object is achieved with the features of
Dank der Erfindung ist es möglich, in besonders vorteilhafter Weise Schutzwände herzustellen, die einen wirksamen Erosionsschutz von übersteilen Böschungen und deren dauerhafte Begrünbarkeit sicherstellen. Die Elemente lassen sich aber genauso zu Rahmen bekannter Art zusammenbauen, um beliebig viele, namentlich stufenförmige Schutzwände selbsttragend zu erstellen, die guten Lärmschutz gewährleisten und überdies mannigfacher gärtnerischer Gestaltung Zugänglich sind. Dabei ist es besonders günstig, daß mittels der Verbindungs- bzw. Verankerungsstreben Zugleich die Neigung des Elements bzw. der Elemente einstellbar ist, wodurch der Aufbau in optimaler Weise den örtlichen Gegebenheiten angepaßt werden kann. Die Schutzwände können aus den erfindungsgemäßen Elementen stufenförmig angeordnet werden, um sogenannte Bermen Zu erhalten, d.h. waagerechte oder schwach geneigte Böschungsabsätze, die sich leicht bepflanzen lassen und Regenwasser auffangen können.Thanks to the invention, it is possible to produce protective walls in a particularly advantageous manner, which ensure effective erosion protection of excessively steep embankments and their permanent greening. However, the elements can also be assembled into frames of a known type in order to create any number of self-supporting, in particular step-like protective walls, which ensure good noise protection and are also accessible to a variety of horticultural design. It is particularly favorable that the inclination of the element or elements can be adjusted at the same time by means of the connecting or anchoring struts, as a result of which the structure can be optimally adapted to the local conditions. The protective walls can be arranged in steps from the elements according to the invention in order to obtain so-called berms, i.e. horizontal or slightly sloping bank heels that are easy to plant and can collect rainwater.
Da die Halteprofile länglich gestaltete Faltkörper mit einer Hohlkehle sind und gemäß Anspruch 2 wenigstens einen nach außen vorstehenden Mittelbereich mit anschließenden Seitenteilen haben, sind derartige Halteelemente vor allem in der Ausgestaltung nach Anspruch 4 von besonders hoher Stabilität. Ihre sehr schmale Stirnfläche tritt optisch nur untergeordnet in Erscheinung, was zu einem vorteilhaften Straßen- bzw. Landschaftsbild beiträgt.Since the holding profiles are elongated folding bodies with a groove and, according to claim 2, have at least one outwardly projecting central region with adjoining side parts, holding elements of this type are above all in the embodiment according to claim 4 of particularly high stability. Its very narrow frontal surface appears only subordinate, which contributes to an advantageous street or landscape picture.
Sehr vorteilhaft ist die Weiterbildung von Anspruch 9, wonach die Halteprofile im Mittelbereich bzw. am Stirnteil mit gestreckten Ausnehmungen versehen sind, welche namentlich laut Anspruch 10 im Rastermaß der Vlies- bzw. Matten-Tragteile angeordnet sind. In die Hohlkehle der Halteprofile lassen sich gemäß Anspruch 11 Stäbe einführen, um die außen vorgeordneten Vliese, Netze, Matten oder dergleichen von innen und mithin unauffällig zu sichern. Zugleich wird dadurch eine Schwächung vermieden, die herkömmlich durch Aufschneiden von Löchern für Pflanzen stattfand. Die Haltekonstruktion gemäß den Ansprüchen 12 bis 14 ist diesbezüglich besonders vorteilhaft.The further development of claim 9 is very advantageous, according to which the holding profiles are provided in the central region or on the end part with elongated recesses which, according to
Zweckmäßige Ausgestaltungen der Anschlüsse zwischen den Streben und den Halteprofilen sind in den Ansprüchen 15 und 16 angegeben.Appropriate configurations of the connections between the struts and the holding profiles are given in
Die Weiterbildungen nach den Ansprüchen 17 bis 19 gestatten einen stabilen Rahmenaufbau für selbsttragende Schutzwände in grundsätzlich beliebig wählbarer Anordnung.The further developments according to claims 17 to 19 permit a stable frame structure for self-supporting protective walls in a basically arbitrary arrangement.
Hohe Festigkeit bei minimalem Materialaufwand und Gewicht stellt die Maßnahme des Anspruches 20 sicher.The measure of

Ein allgemein mit 10 bezeichnetes Element ist ein Halteprofil, das aus einem verzinktem Blechteil gemäß Fig. 1 herstellbar ist. An seinen Mittelbereich schließen beiderseits Seitenteile 14 an, die unten und oben mit Schrägkanten 16 versehen sind. Parallel zu den in Längsrichtung L verlaufenden Seitenkanten sind Befestigungslöcher 18 mit einem vorzugsweise regelmäßigen Lochabstand M vorhanden. Der Mittelteil 12 weist Ausnehmungen 20 auf, die als quer verlaufende, insbesondere rechteckige Ausstanzungen gestaltet und in Längsrichtung L in einem Rastermaß D angeordnet sind. Durch Faltung bzw. Abkantung im Mittelbereich 12 wird ein auswärts gewölbter Stirnteil 22 gebildet, dessen Inneres eine Hohlkehle 60 bildet (vergl. Fig. 2, 6, 7).An element, generally designated 10, is a holding profile which can be produced from a galvanized sheet metal part according to FIG. 1. At its central region,
Wird das erfindungsgemäße Element 10 für Schutzwände an Steilböschungen (Fig. 4), Fels- oder Betonwänden (Fig. 5) oder in Form selbsttragender Rahmen (Fig. 8 bis 10) eingesetzt, so wird ein hinterfülltes Humussubstrat H von einem in Fig. 3 schematisch angedeuteten Vlies 30 gehalten, das auch ein Netz oder Stützgewebe für die sich entwickelnde Vegetation sein kann. Darüber liegen die Halteprofile 10, die mittels Streben 24 am Untergrund U verankerbar sind (Fig. 3 bis 5) oder den Rahmenaufbau ermöglichen (Fig. 6). Die Streben 24 sind bevorzugt als Zugbänder ausgebildet und haben wenigstens einen Anschlußteil 26 mit einem Schraubloch 46 (Fig. 7). Die Anschlußteile 26 werden durch eine weiter unten erörterte Befestigung an den Löchern 18 der Halteprofile 10 festgelegt. Durch geeignete Wahl und Bemessung bestimmen die Streben 24 dabei die Neigung des Halteprofils 10 gegenüber dem Untergrund U.If the
Zur äußeren Sicherung dienen Matten 32, deren Trägerdrähte 34 bis an die Stirnkanten 42 der Ausnehmungen 20 in diese einführbar sind. Zu diesem Zweck ist das Rastermaß D gleich dem Normabstand der Trägerdrähte 34 gewählt. Letztere werden in ihrer Postion durch Stäbe 28 gesichert, die in Längsrichtung L in die Hohlkehle 60 so eingeführt werden, daß sie zwischen den Stirnteilen 22 und den Trägerdrähten 34 beiderseits abgestützt bzw. abstützbar sind.
Man erkennt, daß die Schrägkanten 16 die Anbringung der Halteprofile 10 allgemein erleichtern und auch das Aufstützen an einem Bodenbereich oder an Bermen begünstigen, wie aus Fig. 4 und 5 hervorgeht. Die Verankerung der Streben 24 kann sowohl in felsigem Untergrund als auch an Betonwänden B (Fig. 5) in an sich bekannter Weise erfolgen, so daß mit den erfindungsgemäßen Elementen 10 bewachsene Futtermauern für übersteile Böschungen rasch und zuverlässig herstellbar sind.It can be seen that the
Eine selbsttragende Anordnung ist aus Fig. 6 ersichtlich. Hierbei sind zwei Elementpaare 10a, 10b bzw. 10c, 10d jeweils untereinander durch Streben 24 verbunden, wobei eine mittlere Strebe einen abgewinkelten Übergang ermöglich, Dazu können die einzelnen Elemente 10 in einem Eck- bzw. Randbereich 36 Lochpaare 38 aufweisen, die mit entsprechenden Schraublöchern 46 der mittleren Strebe 24 übereinstimmen. Letztere ist trapezförmig ausgebildet, so daß das untere Elementpaar 10c, 10d über das obere Elementpaar 10a, 10b nach außen vorsteht. Die Länge der untersten Strebe 24 bestimmt die Neigung bzw. den Böschungswinkel der unteren Elemente 10c, 10d. Alle diese Elemente können wiederum hinter (nicht dargestellten) Vliesen mit geeignetem Material gefüllt werden, wobei zur Sicherung Baustahlmatten dienen können, von denen in Fig. 6 lediglich links oben Trägerdrähte 34 angedeutet sind, die wiederum durch in Längsrichtung L eingeschobene Stäbe 28 vor den Hohlkehlen 60 der Stirnteile 22 gehalten sind.A self-supporting arrangement can be seen in FIG. 6. Here, two
Die Schnittansicht der Fig. 7 veranschaulicht eine vorteilhafte Befestigung eines Elements 10, dessen Seitenteile 14 mit einer Strebe 24 über deren Anschlußteil 26 verbunden sind. Wie dargestellt, durchragt der Stirnteil 22 eine doppelte Mattenanordnung 32, deren Trägerdrähte 34 durch angeschweißte Flacheisen 58 gegen Durchrutschen gesichert und zusätzlich mittels Haltedrähten oder -stäben 40 untereinander verfestigt sind. Zur Abspannung dienen die Stäbe 28, die vor den Trägerdrähten 34 in die Hohlkehle 60 eingesteckt sind.The sectional view of FIG. 7 illustrates an advantageous fastening of an
Der Anschlußteil 26 der Strebe 24 ist an dem Halteprofil 10 gemäß Fig. 7 mittels einer Schaftschraube oder eines Bolzens 44 festgelegt, die bzw. der die Befestigungslöcher 18, 46 durchsetzt und mittels Sicherungsscheibe 50 sowie Mutter 52 fest verschraubt ist. Man erkennt, daß mehrere Schraublöcher 18 bzw. 46 in passender Anordnung vorgesehen sein können, um wahlweise optimalen Anschluß der Streben 24 an den Elementen 10 zu bewirken. Günstig ist es, wenn Distanzhülsen 48 dafür sorgen, daß die Seitenteile 14 des Halteprofils an der Anschlußstelle einen vorgewählten Mindestabstand besitzen. Dieser ist mindestens so groß wie die Breite des Stirnteiles 22, wenn das Element 10 als U-oder V-Profil ausgebildet ist.The connecting
In den Fig. 8 bis 10 sind Aufbaubeispiele für Rahmen R nach Art von Fig. 6 dargestellt. Man erkennt, daß diese Rahmen R sich nach oben pyramidenförmig verjüngen können, wobei die Länge der (hier nicht gezeichneten) Streben den Neigungsbzw. Böschungswinkel jedes Paares von Elementen 10 bestimmt. Durch Vliese und Matten 32 wird die Hinterfüllung mit dem Humussubstrat H gesichert, aus dem die Begrünung G wächst.8 to 10 show construction examples for frame R in the manner of FIG. 6. It can be seen that these frames R can taper pyramid-shaped, the length of the struts (not shown here) the inclination or. Slope angle of each pair of
