Abstract

The invention relates to protective devices, especially for sound protection in the form of embankments or slopes. Structures consisting of transverse wall elements and longitudinal wall parts and to be filled with a filler, especially earth, are used. To reduce sound reflections by the longitudinal wall parts, these are given a profile shape differing from a straight line. <IMAGE>

Description

Es ist (DE-PS 25 32 52o) eine solche Schutzvorrichtung bekannt, bestehend aus vorgefertigten Querwandelementen und Längswandteilen aus Kunststoff, Beton oder dergleichen, wobei die Anordnung zur Aufnahme von Füllmaterial dient und wobei die Querwandelemente als Stützkörper mit von unten nach oben stufenförmig versetzten Aufnahmen für die im wesentlichen plattenförmigen Längswandteile ausgebildet sind. Diese bekannte Vorrichtung hat den Vorteil, daß, obwohl als Füllmaterial Erdreich verwendet wird, sich erheblich steilere Böschungswinkel erzielen lassen, als dies bei Erdwällen der Fall war. Hierdurch läßt sich der Flächenbedarf für die Schutzvorrichtungen erheblich vermindern, ohne daß auf das besonders kostengünstige und schalldämpfungswirksame Erdreich zu Gunsten anderer Baumaterialien verzichtet werden müßte.Such a protective device is known (DE-PS 25 32 52o), consisting of prefabricated transverse wall elements and longitudinal wall parts made of plastic, concrete or the like, the arrangement serving to accommodate filler material and the transverse wall elements as a support body with receptacles staggered from bottom to top are formed for the substantially plate-shaped longitudinal wall parts. This known device has the advantage that, although soil is used as the filling material, considerably steeper slope angles can be achieved than was the case with earth walls. As a result, the space requirement for the protective devices can be reduced considerably without having to do without the particularly inexpensive and sound-absorbing soil in favor of other building materials.

Bei der bekannten Vorrichtung müssen jedoch die plattenförmig ausgebildeten Längswandteile, um das Hinausrieseln des Erdreiches zu verhindern, verhältnismäßig steil zur Bodenebene angeordnet werden, also mit einem nur kleinen Winkel gegen die Senkrechte. Dies wiederum hat zur Folge, daß die Schutzvorrichtung verhältnismäßig große außenliegende Flächen der Längswandteile aufweist, die, üblicherweise, aus Beton, Kunststein oder einem ähnlichen Material hergestellt, schallreflektierend wirken. Diese Schallreflektion führt zu einer unerwünschten Erhöhung des Geräuschpegels in dem Bereich, in dem der Schall entsteht, also etwa auf derivon der Schutzvorrichtung umgebenen Straße, aber schließlich auch zu einer Geräuschbelastung der jenseits der Schutzvorrichtung befindlichen Umgebung.In the known device, however, the plate-shaped longitudinal wall parts have to trickle out to prevent the soil from being arranged relatively steeply to the ground level, that is to say with only a small angle to the vertical. This in turn has the consequence that the protective device has relatively large outer surfaces of the longitudinal wall parts, which, usually made of concrete, artificial stone or a similar material, have a sound-reflecting effect. This sound reflection leads to an undesirable increase in the noise level in the area in which the sound is generated, that is to say, for example, on the road surrounded by the protective device, but ultimately also to a noise pollution in the environment located beyond the protective device.

Man könnte zwar die schallreflektierenden Flächen der Längswandteile mit schallabsorbierenden Beschichtungen versehen, um diese Nachteile zu verringern. Hierzu müßten jedoch beträchtliche Kosten aufgewendet werden, da schon Beschichtungen mit verhältnismäßig geringer Wirksamkeit etwa die Hälfte der Herstellungskosten unbeschichteter Längswandteile betragen würden.It is true that the sound-reflecting surfaces of the longitudinal wall parts could be provided with sound-absorbing coatings in order to reduce these disadvantages. To do this, however, considerable costs would have to be incurred since even coatings with a relatively low effectiveness would amount to about half the production costs of uncoated longitudinal wall parts.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Schutzvorrichtung in ihrer schallabsorbierenden Wirkung zu verbessern, ihre Herstellung zu verbilligen und für die Schallabsorption größere Flächen an Erdreich zur Verfügung zu stellen, wobei diese Flächen, wenn bepflanzt, die ästhetische Wirkung des Bauwerkes verbessern können.The invention has for its object to improve the protective device mentioned in its sound-absorbing effect, to make it cheaper and to make larger areas of soil available for sound absorption, these areas, when planted, can improve the aesthetic effect of the building.

Gegenstand der Erfindung ist eine Schutzvorrichtung, insbesondere Schallschutzeinrichtung und Böschungsbefestigung, insbesondere für Straßen, bestehend aus vorgefertigten Querwandelementen und Längswandteilen aus,Kunststein, Beton oder dergleichen zur Aufnahme von Füllmaterial, wobei die Querwandelemente als Stützkörper mit von unten nach oben stufenförmig versetzten Aufnahmen für die im wesentlichen plattenförmigen Längswandteile ausgebildet sind, die dadurch gekennzeichnet ist, daß die Längswandteile ein Querschnittsprofil,aufweisen, das aus einer Hauptplatte und einer in einem Winkel zur Ebene der Hauptplatte verlaufenden und mit dieser verbundenen Schürze besteht.The invention relates to a protective device, in particular soundproofing device and embankment attachment, in particular for roads, consisting of prefabricated transverse wall elements and longitudinal wall parts made of, artificial stone, concrete or The like for receiving filler material, the transverse wall elements being designed as support bodies with receptacles which are staggered from bottom to top for the essentially plate-shaped longitudinal wall parts, which is characterized in that the longitudinal wall parts have a cross-sectional profile consisting of a main plate and one at an angle to the level of the main plate extending and connected to this apron.

Bei der Vorrichtung gemäß der Erfindung dient das gesamte Längswandteil zu einer gegenüber dem Stand der Technik verbesserten Stützung des Erdreiches oder anderen Füllmaterials, während nur ein kleiner Teil der Fläche des Längswandteiles schallreflektierend wirkt, wobei auch noch der Vorteil entsteht, daß ein Teil des reflektierten Schalles auf schallabsorbierendes Erdreich gelenkt wird.In the device according to the invention, the entire longitudinal wall part is used to support the soil or other filler material compared to the prior art, while only a small part of the surface of the longitudinal wall part has a sound-reflecting effect, with the additional advantage that part of the reflected sound is directed onto sound-absorbing soil.

Um hierbei bestmögliche Ergebnisse zu erzielen, ist es zweckmäßig, daß der Winkel zwischen Hauptplatte und Schürze stumpf ist, beispielsweise etwa 12o Grad beträgt, weiterhin daß im Querschnii gesehen, die Schürze kürzer ist als die Hauptplatte, wobei vorzugsweise das Längenverhältnis etwa 1 zu 2,6 beträgt.In order to achieve the best possible results, it is expedient that the angle between the main plate and the apron is obtuse, for example, is approximately 120 degrees, and furthermore that, viewed in cross section, the apron is shorter than the main plate, the aspect ratio preferably being about 1 to 2, 6 is.

Um Schallreflektionen weiterhin zu vermindern, kann die der Hauptplatte abgewandte Fläche der Schürze mit einer schallabsorbierenden Beschichtung versehen sein. Da diese Fläche klein ist, entstehen hierfür nur geringe Kosten um eine nahezu vollständige Schallabsorption zu erreichen.In order to further reduce sound reflections, the surface of the apron facing away from the main plate can be provided with a sound-absorbing coating. Since this area is small, there are only low costs to achieve almost complete sound absorption.

Die Hauptplatte des Längswandteiles kann an ihrem der Schürze gegenüberliegenden Ende mit einem etwa rechtwinklig zu ihr verlaufenden Ansatz versehen sein. Dieser Ansatz wirkt mit dem Auflager des Längswandteiles auf dem Querwandelement zusammen und verhindert das Hinausschieben des Längswandteiles aus dem Querwandelement unter dem Druck des Erdreiches.The main plate of the longitudinal wall part can be provided at its end opposite the skirt with an approximately perpendicular extension to it. This approach operates with the support of the County swandteiles g on the transverse wall member together and prevents the pushing out of the longitudinal wall part from the transverse wall member under the pressure of the soil.

Besonders zweckmäßig ist es, das Längswandteil auf dem Querwandelement so aufliegen zu lassen, daß seine Hauptplatte in Richtung auf die Schürze ansteigend in einem Winkel zur Ebene verläuft, wodurch ebenfalls das Hinausschieben des Längswandteiles aus dem Querwandelement vermieden wird. Dieser Winkel kann zweckmäßig etwa 12 Grad betragen.It is particularly expedient to let the longitudinal wall part rest on the transverse wall element in such a way that its main plate rises towards the apron at an angle to the plane, which also prevents the longitudinal wall part from being pushed out of the transverse wall element. This angle can usefully be about 12 degrees.

Weiterhin kann der Höhenabstand zweier aufeinanderfolgender Längswandteile größer sein als die projizierte Länge des Querschnittes der Längswandteile, wobei dieses Verhältnis etwa 1,17 zu 1 betragen kann. Hierdurch wird in der Vorrichtung eine besonders große Fläche an Füllmaterial dargeboten, ohne daß das Füllmaterial hinausrieseln könnte.Furthermore, the height distance between two successive longitudinal wall parts can be greater than the projected length of the cross section of the longitudinal wall parts, this ratio being approximately 1.17 to 1. As a result, a particularly large area of filling material is presented in the device without the filling material being able to trickle out.

Ein Ausführungsbeispiel der Vorrichtung gemäß der Erfindung ist im folgenden anhand der Zeichnung beschrieben, in der

  • Figur 1 einen Querschnitt durch die Vorrichtung,
  • Figur 2 eine Seitenansicht der Vorrichtung und
  • Figur 3 in vergrößertem Maßstab einen Ausschnitt aus Figur 1 zeigt.
An embodiment of the device according to the invention is described below with reference to the drawing, in which
  • FIG. 1 shows a cross section through the device,
  • Figure 2 is a side view of the device and
  • FIG. 3 shows a detail from FIG. 1 on an enlarged scale.

Im Ausführungsbeispiel ist die Erfindung anhand einer einseitig wirkenden Schallschutzvorrichtung dargestellt, wobei es sich um eine Böschungsbefestigung handeln kann. Das Querwandelement ist in Figur 1 in seiner Gesamtheit mit 11 bezeichnet. Es besteht aus einem zur Aufnahme der Längswandteile 12 dienenden Stützbalken 13, sowie einem weiteren rückwärtigen Stützbalken 14. Die Stützbalken 13 und 14 ruhen mit Füßen 15 und 16 auf einem Fundamentblock 17. Zwischen den Stützbalken 13 und 14 sind Querbalken 18 angeordnet.In the exemplary embodiment, the invention is illustrated on the basis of a one-sided soundproofing device, which can be an embankment attachment. The transverse wall element is designated 11 in its entirety in FIG. It consists of a support beam 13 for receiving the longitudinal wall parts 12, as well as a further rear support beam 14. The support beams 13 and 14 rest with feet 15 and 16 on a foundation block 17. Cross beams 18 are arranged between the support beams 13 and 14.

Die in Figur 1 dargestellte Ausführungsform kann, wenn eine beiderseitig wirksame Lärmschutzwand erforderlich ist, auch dahingehed abgeändert werden, daß der Stützbalken 14 in gleicher Weise wie der Stützbalken 13 ausgebildet ist und ebenso Längswandteile 12 trägt. Bei einer einseitigen Lärmschutzwand kann bei definierten Lagerpunkten für das obere und das untere Ende des Stützbalkens 13 der Stützbalken 14 entfallen.The embodiment shown in FIG. 1 can, if a mutually effective noise barrier is required, also be modified such that the support bar 14 is designed in the same way as the support bar 13 and also carries longitudinal wall parts 12. In the case of a noise barrier on one side, the support beam 14 can be omitted at defined bearing points for the upper and the lower end of the support beam 13.

Die Ausbildung und Anordnung der Längswandteile sind besonders deutlich aus Figur 3 zu entnehmen, einem vergrößerten Ausschnitt aus Figur 1. Die Längswandteile bestehen aus einer Hauptplatte 19 und einer damit verbundenen Schürze 20. Die Schürze 2o ist mit der Hauptplatte 19 einstückig ausgeführt und verläuft in einem stumpfen Winkel zur Hauptplatte, vorzugsweise in einem Winkel von 12o Grad. Die Hauptplatte 19 liegt auf einer mit dem Stützbalken 13 verbundenen Konsole 21 auf. Die Oberfläche des als Füllmaterials dienenden Erdreiches ist mit 22 bezeichnet.The design and arrangement of County g swandteile are shown particularly clearly in Figure 3, an enlarged detail of Figure 1. The longitudinal wall parts consist of a main plate 19 and an associated skirt 2 0th The apron 2o is made in one piece with the main plate 19 and extends at an obtuse angle to the main plate, preferably at an angle of 12o degrees. The main plate 19 rests on a bracket 21 connected to the support beam 13. The surface of the soil serving as filler material is designated by 22.

In Figur 3 ist unten ein weiteres Ausführungsbeispiel eines Längswandteiles dargestellt, bei dem sich an die Hauptplatte 19 etwa rechtwinklig ein Ansatz 22 anschließt, der mit der Konsole 21 derart zusammenwirkt, daß das Hinausschieben des Längswandteiles 12 aus dem Stützbalken 13 verhindert wird. Um zu verhindern, daß durch die außenliegenden Flächen der Schürzen 2o eine Schallreflektion auf die Schallquelle stattfindet, können diese verhältnismäßig kleinen Flächen mit einer schallabsorbierenden Beschichtung 23 versehen werden, es sei denn, daß der Bewuchs auf der Hauptplatte 19 der Schürze 2o zur überdeckung der freiliegenden Fläche der Schürze 2o führt.In Figure 3, another embodiment of a longitudinal wall part is shown below, in which an approximately 22 adjoins the main plate 19 approximately at right angles, which interacts with the bracket 21 in such a way that the longitudinal wall part 12 is prevented from being pushed out of the support beam 13. In order to prevent sound reflection from occurring on the sound source through the outer surfaces of the aprons 2o, these relatively small areas can be provided with a sound-absorbing coating 23, unless the vegetation on the main plate 19 of the apron 2o to cover the exposed ones Surface of the apron 2o leads.

In Figur 2 sind die sichtbaren Flächen 2o bzw. die Beschichtungen 23 der Schürzen zu erkennen sowie die Erdreichoberflächen 22. Die Stützbalken 13 sowie die Konsolen 21 sind nur schematisch dargestellt.In Figure 2, the visible surfaces 20 and the coatings 23 of the aprons can be seen as well as the soil surfaces 22. The support beams 13 and the brackets 21 are only shown schematically.
