A set of retaining wall elements for the construction of a plantable retaining wall, wherein each element (1, 7, 13, 15, 18) has an essentially rectangular form with framelike walls, at least one (3) of said walls being raised as compared with the surface of the other walls, characterized in that the walls (2, 3 ; 9, 10 ; 19, 20) of the elements (1, 7, 13, 15, 18) having a through opening are convex and that at a standard element (1, 18) the two walls (2) adjacent the raised wall (3) comprise each at the surface a locking cam (4).

Description

Die vorliegende Erfindung bezieht sich auf einen Satz von Stützmauerelementen zur Erstellung einer bepflanzten Stützmauer, wobei jedes Element eine im wesentlichen rechteckige Form mit rahmenförmigen Wänden aufweist, von denen mindestens eine Wand gegenüber der Oberseite der übrigen Wände hochgezogen ist.The present invention relates to a set of retaining wall elements for creating a planted retaining wall, each element having a substantially rectangular shape with frame-shaped walls, at least one wall of which is raised opposite the top of the other walls.

Es sind eine Vielzahl von Böschungssteinen und Elementen für das Errichten von Stützmauern bekannt, jedoch sind diese entweder nicht mit einer durchgehenden Öffnung versehen (FR-A 2 285 494), so dass gerade auf die untersten Reihen ein sehr grosser Druck von den darüberliegenden Böschungssteinen und von der Erde und vom Humus ausgeübt wird, und sie gestatten es nur unter grosser Mühe, auch schwierige Böschungen zu folgen oder es sind offene, langgestreckte Elemente (DE-A-2 809 892), die nur beschränkt die Bildung von gekrümmten Stützmauern zulassen. Ausserdem ist die gegenseitige Verankerung der einzelnen Elemente im wesentlichen nur in der Längsrichtung wirksam.A large number of embankment stones and elements for the erection of retaining walls are known, but these are either not provided with a continuous opening (FR-A 2 285 494), so that especially on the bottom rows there is very great pressure from the embankment stones and above is exercised by the earth and by the humus, and they only permit great difficulty to follow difficult embankments or they are open, elongated elements (DE-A-2 809 892) which only permit the formation of curved retaining walls to a limited extent. In addition, the mutual anchoring of the individual elements is essentially only effective in the longitudinal direction.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung, einen Satz von Stützmauerelementen zu schaffen, der es gestattet, in einfacher und ästhetisch vorteilhafterer Art den Krümmungen einer Böschung zu folgen und der eine bessere Verankerung auch in seitlicher Richtung ermöglicht.In contrast, it is an object of the present invention to provide a set of retaining wall elements which makes it possible to follow the curvatures of an embankment in a simple and aesthetically more advantageous manner and which also enables better anchoring in the lateral direction.

Diese Aufgabe wird dadurch gelöst, dass die Wände der eine durchgehende Öffnung aufweisenden Elemente nach aussen ausgebaucht sind und dass bei einem ganzen Normalelement jeweils eine Wand hochgezogen ist und die beiden angrenzenden Wände je einen Haltenocken aufweisen. Vorteilhafte Ausgestaltungen dieser Elemente sind Gegenstand der Ansprüche 2-8.This object is achieved in that the walls of the elements having a continuous opening are bulged outwards and that in the case of a whole normal element, one wall is raised and the two adjacent walls each have a retaining cam. Advantageous embodiments of these elements are the subject of claims 2-8.

Ferner betrifft die Erfindung die Verwendung derartiger Elemente zum Hochziehen einer lotrechten Mauer, wonach auf jede Lage mit längsliegenden Elementen eine Lage mit querliegenden Elementen folgt.Furthermore, the invention relates to the use of such elements for raising a vertical wall, after which each layer with longitudinal elements is followed by a layer with transverse elements.

Die Erfindung wird nun anhand einer Zeichnung von Ausführungsbeispielen näher erläutert werden. Es zeigen:

  • Fig. 1 in perspektivischer Sicht ein ganzes Element,
  • Fig. in Draufsicht ein unter zwei anderen Elementen liegendes Element,
  • Fig. 3 in perspektivischer Sicht und in verkleinertem Massstab mehrere aufeinanderliegende Elemente,
  • Fig.4 drei aufeinanderliegende Elemente im Schnitt,
  • Fig. 5 in perspektivischer Sicht und in verkleinertem Massstab. mehrere Lagen von Elementen an einer Böschung,
  • Fig. 6 in perspektivischer Sicht und in verkleinertem Massstab senkrecht als Stützmauer aufeinanderliegende Elemente,
  • Fig. 7 in Draufsicht mehrere aufeinanderliegende Elemente, und
  • Fig. 8 im Schnitt ein zweites Ausführungsbeispiel eines Elementes mit Bodeneinsatz.
The invention will now be explained in more detail with reference to a drawing of exemplary embodiments. Show it:
  • 1 is a perspective view of an entire element,
  • FIG. 1 shows a top view of an element lying under two other elements,
  • 3 in a perspective view and on a reduced scale several superimposed elements,
  • 4 shows three superimposed elements in section,
  • Fig. 5 in a perspective view and on a reduced scale. several layers of elements on an embankment,
  • 6 is a perspective view and on a reduced scale vertically superimposed elements as a retaining wall,
  • Fig. 7 in plan view several superimposed elements, and
  • Fig. 8 in section a second embodiment of an element with a bottom insert.

In Fig. 1 erkennt man ein ganzes Normalelement 1, das im wesentlichen rechteckig ist und zwei ausgebauchte längere Seitenwände 2 und zwei ausgebauchte kürzere Seitenwände 3 aufweist. Das Element wird, wie in der Zeichnung, liegend auf den Boden oder auf der Böschung verlegt, so dass die beiden Haltenocken 4 an den Längsseiten 2 und die sich über eine ganze Querseite 3 erstreckende Halteschulter 5 oben zu liegen kommen. Auf der Unterseite, im vorliegenden Beispiel an den Längsseiten 2, sind je eine Aussparung 6 angebracht, um das Element 1 unterfassen und hochheben zu können. Diese Aussparungen 6 können selbstverständlich auch an den Querseiten oder an allen vier Seiten angeordnet sein.1 shows an entire normal element 1, which is essentially rectangular and has two bulged longer side walls 2 and two bulged shorter side walls 3. As in the drawing, the element is laid horizontally on the ground or on the embankment, so that the two holding cams 4 on the long sides 2 and the holding shoulder 5 extending over an entire transverse side 3 come to lie at the top. On the underside, in the present example on the long sides 2, a recess 6 is made in each case in order to be able to grasp the element 1 and lift it up. These recesses 6 can of course also be arranged on the transverse sides or on all four sides.

In Fig. 2 erkennt man zwei Lagen von ganzen Normalelementen, wobei die obere Lage strichpunktiert eingezeichnet ist. Man erkennt deutlich, dass insbesondere durch die seitlichen Haltenokken 4 eine Verankerung in der Querrichtung möglich ist, und dass durch die Ausbauchung der Wände eine sehr grosse Freiheit bezüglich einer Krümmung vorhanden ist. Auch ist ersichtlich, dass sich die Querwände 3' der oberen Lage gegen die ausgebauchten Innenflächen 5' der Halteschulter 5 der unteren Lage abstützen. In den Fig. 3 und 4 erkennt man den Aufbau einer Stützmauer an einer Böschung, wobei insbesondere auch die Verzahnung an der Halteschulter 5 der Vorderwand 3 ersichtlich ist.2 shows two layers of whole normal elements, the upper layer being shown in dash-dot lines. It can clearly be seen that anchoring in the transverse direction is possible, in particular, by the lateral holding cams 4, and that there is a great deal of freedom in terms of curvature due to the bulging of the walls. It can also be seen that the transverse walls 3 'of the upper layer are supported against the bulged inner surfaces 5' of the holding shoulder 5 of the lower layer. 3 and 4, the construction of a retaining wall on an embankment can be seen, in particular the toothing on the holding shoulder 5 of the front wall 3 can also be seen.

In Fig. 5 erkennt man eine Anordnung der Elemente, worin einerseits ganze Eckelemente 7 verwendet werden, die nur zwei Halteschultern in Form von hochgezogenen Wänden 9, 10 aufweisen und anderseits Halbelemente 13, deren Länge der Breite von ganzen Elementen 1 entspricht. Im vorliegenden Beispiel weisen die Halbelemente 13 eine Halteschulter 14 auf. Aus Fig. 5 wird besonders deutlich, dass durch die Verwendung eines Satzes von Elementen, der ganze und halbe und ganze Eckelemente enthält, eine sehr grosse Anpassungsfähigkeit vorhanden ist, wobei die Elemente in einer ästhetisch gefälligen Form und vor allem untereinander in allen Richtungen verankert angeordnet sind. Da es sich um rahmenförmige Elemente handelt, ist die Möglichkeit gegeben, diese mit Erdreich, Kies und Humus auszufüllen und zu bepflanzen, wodurch eine Erhöhung der Festigkeit und Verankerung und eine Verschönerung der Böschung erreicht wird.5 shows an arrangement of the elements, in which on the one hand whole corner elements 7 are used which only have two holding shoulders in the form of raised walls 9, 10 and on the other hand half elements 13, the length of which corresponds to the width of entire elements 1. In the present example, the half-elements 13 have a holding shoulder 14. From Fig. 5 it is particularly clear that the use of a set of elements, which contains whole and half and whole corner elements, provides a very high degree of adaptability, the elements being arranged in an aesthetically pleasing form and above all anchored in all directions are. Since the elements are frame-shaped, it is possible to fill them with soil, gravel and humus and plant them, which increases the strength and anchorage and improves the embankment.

In Fig. 6 ist dargestellt, wie mittels der Elemente 1, 13 eine Stützmauer lotrecht nach oben gezogen werden kann. Zu diesem Zweck wird die nachfolgende Lage jeweils um 90° gedreht quer auf die erste Lage gelegt, wobei die seitlichen Abschlüsse der querliegenden Lagen jeweils durch Halbelemente 13 gebildet werden.FIG. 6 shows how a retaining wall can be pulled vertically upwards by means of the elements 1, 13. For this purpose, the subsequent layer is rotated 90 ° and placed transversely on the first layer, the lateral ends of the transverse layers each being formed by half elements 13.

In Fig. 7 ist die Verwendung von Halbelementen 15 mit einer Halteschulter 16 und zwei Haltenokken 17 an den entgegengesetzten Ecken dargestellt. Beim Vergleich dieser Halbelemente 15 mit dem ganzen Element 1 gemäss Fig. 2 ist ersichtlich, dass diese Halbelemente 15 durch Verwendung der gleichen Giessform, mit einer Trennwand, hergestellt werden können. Solche Halbelemente 15 können beispielsweise für die Bildung von Ecken, wie in Fig. 7 dargestellt, verwendet werden, wobei ein Teil eines Haltenockens 4' eines ganzen Elementes 1 weggeschlagen werden muss. Auch in dieser Fig. 7 ist die Längs- und Querverankerung der Elemente 1, 15 klar ersichtlich. Vergleicht man das Halbelement 15 mit dem ganzen Element 1, ersieht man, dass das Halbelement 15 in das Element 1 gestellt werden kann. Da in der Regel viel weniger Halbelemente 15 als ganze Elemente 1 verwendet werden, ist beim Versand der Elemente eine erhebliche Volumeneinsparung möglich, da es in den meisten Fällen genügt, die oberste Lage mit Halbelementen 15 auszufüllen.7 shows the use of half elements 15 with a holding shoulder 16 and two holding elements ken 17 shown at the opposite corners. When comparing these half elements 15 with the entire element 1 according to FIG. 2, it can be seen that these half elements 15 can be produced by using the same mold, with a partition. Such half elements 15 can be used, for example, for the formation of corners, as shown in FIG. 7, wherein part of a holding cam 4 'of an entire element 1 has to be knocked away. 7, the longitudinal and transverse anchoring of the elements 1, 15 is clearly visible. If you compare the half element 15 with the whole element 1, you can see that the half element 15 can be placed in the element 1. Since, as a rule, much fewer half elements 15 are used than whole elements 1, considerable savings in volume are possible when the elements are shipped, since in most cases it is sufficient to fill the top layer with half elements 15.

In Fig. 8 ist ein bevorzugtes Ausführungsbeispiel der ganzen Elemente gezeigt, wobei das Element 18 Querwände 19 und 20 aufweist, die unten eine nach einwärts weisende Verdickung 21 aufweisen und abgerundet sind. Dabei hat die Rundung an der vorderen hochgezogenen Wand 20 einerseits die Aufgabe, den Schüttwinkel S, der durch die gestrichelte und strichpunktierte Gerade angedeutet ist, siehe auch Fig. 4, zu verkleinern und anderseits zusammen mit der Rundung mit der anderen Wand das Einlegen einer Schale 22 zu ermöglichen. Durch das Einlegen solcher Schalen ist es möglich, das Versickern von Wasser zu verhindern und somit an trockenen Stellen eine bessere Befeuchtung des Pflanzgutes zu erzielen.FIG. 8 shows a preferred exemplary embodiment of the entire elements, the element 18 having transverse walls 19 and 20 which have an inward-facing thickening 21 at the bottom and are rounded. The rounding on the front raised wall 20 on the one hand has the task of reducing the angle of repose S, which is indicated by the dashed and dash-dotted straight line, see also FIG. 4, and on the other hand, together with the rounding with the other wall, the insertion of a bowl 22 to enable. By inserting such trays, it is possible to prevent water from seeping away and thus achieve better moistening of the plant material in dry places.

Der Aufbau einer Stützmauer kann selbstverständlich auf die verschiedenste Art und Weise variiert werden, da die angegebenen Elemente eine grosse Vielfalt von Anwendungsmöglichkeiten bieten. Insbesondere können auch die Halbelemente als oberer Abschluss verwendet werden, ausserdem besteht die Möglichkeit, die Elemente durch zusätzliche Verankerungspfähle zu befestigen, falls die Böschung und die Beschaffenheit der Unterlage dies erfordert.The structure of a retaining wall can of course be varied in a wide variety of ways, since the specified elements offer a wide variety of possible uses. In particular, the half-elements can also be used as an upper end, and there is also the option of fastening the elements with additional anchoring piles if the slope and the nature of the underlay require it.
