Abstract
Description
Die Erfindung betrifft eine Einrichtung zum Erstellen von vorzugsweise begrünbaren Böschungen nach dem Oberbegriff des Anspruches 1.The invention relates to a device for creating preferably plantable embankments according to the preamble of
Solche Einrichtungen dienen dazu, beispielsweise im Straßenbau Böschungen zu sichern bzw. zu erstellen. Die Einrichtungen werden mit Bodenmaterial gefüllt, das verdichtet wird. Vor dem Verfüllen der Einrichtung mit dem Bodenmaterial wird auf das Bodengitter ein Geogitter lose aufgelegt oder alternativ kraft- und formschlüssig mit dem Bodengitter verbunden. Beim Auffüllen mit Bodenmaterial kann das nur kraftschlüssig mit dem Bodengitter verbundene Geogitter verrutschen.Such devices serve, for example, to secure or create embankments in road construction. The facilities are filled with soil material that is compacted. Before filling the device with the soil material, a geogrid is placed loosely on the floor grid or alternatively positively and positively connected to the floor grid. When filling with soil material, the geogrid, which is only frictionally connected to the floor grid, can slip.
Es ist bekannt, aus diesem Grunde das Geogitter mit einer stabförmigen Steckschließe am Bodengitter zu befestigen. Die Steckschließe muss von einem Rand des Geogitters so eingefädelt werden, dass senkrecht zur Steckrichtung verlaufende Geogitterdrähte/stäbe abwechselnd oberhalb und unterhalb der Steckschließe verlaufen. Dieser Steckvorgang ist umständlich und zeitaufwändig, insbesondere wenn das Geogitter lang ist. Darum sind in der Regel zwei Personen erforderlich, um das Geogitter zu montieren. Am Bodengitter müssen zudem Halterungsteile, in der Regel Ösen, zum Durchstecken der Steckschließe vorgesehen sein.It is known, for this reason, to attach the geogrid with a rod-shaped plug buckle on the floor grid. The plug-in buckle must be threaded from one edge of the geogrid so that geogrid wires / bars running perpendicular to the direction of insertion run alternately above and below the plug-in buckle. This mating process is cumbersome and time consuming, especially if the geogrid is long. That's why two people are usually required to assemble the geogrid. At the bottom grid also support parts, usually eyelets must be provided for inserting the plug-in buckle.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Einrichtung so auszubilden, dass sie einfach, mit geringem Zeitaufwand und kostengünstig errichtet werden kann.The invention has the object of providing the generic device in such a way that it can be easily, inexpensively and with little expenditure of time.
Diese Aufgabe wird bei der gattungsgemäßen Einrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic device according to the invention with the characterizing features of
Bei der erfindungsgemäßen Einrichtung ist das Bodengitter an seinem vom Frontgitter abgewandten Rand mit Haken versehen. Sie dienen als Formschlussmittel zur Befestigung des Geogitters. Die Haken des Bodengitters umgreifen einen der Geogitterdrähte/stäbe des Geogitters. Der Einhakvorgang lässt sich einfach, innerhalb kürzester Zeit und mit nur einer Person problemlos durchführen. Dadurch können die erfindungsgemäßen Einrichtungen innerhalb kürzester Zeit kostengünstig erstellt werden.In the device according to the invention, the floor grid is provided at its edge facing away from the front edge with hooks. They serve as positive locking means for attaching the geogrid. The hooks of the floor grid surround one of the geogrid wires / bars of the geogrid. The hooking process is simple and can be done easily within a very short time and with just one person. As a result, the inventive devices can be created inexpensively within a very short time.
Vorteilhaft sind die Haken durch umgebogene Enden zumindest eines Teils der Gitterdrähte/stäbe des Bodengitters gebildet.Advantageously, the hooks are formed by bent ends of at least part of the grid wires / bars of the floor grid.
Damit der erforderliche Böschungswinkel, den das Bodengitter und das Frontgitter einschließen, beim Auffüllen mit Bodenmaterial nicht verändert wird, sind vorteilhaft das Bodengitter und das Frontgitter durch wenigstens ein Stützelement aneinander abgestützt.So that the required slope angle, which include the floor grid and the front grille, is not changed during filling with soil material, the bottom grid and the front grille are supported by at least one support element to each other advantageous.
Bei einer Ausführungsform sind das Bodengitter und das Frongitter einstückig miteinander ausgebildet. Das Frontgitter wird entsprechend dem Böschungswinkel gegenüber dem Bodengitter gebogen.In one embodiment, the floor grid and the fritter are formed integrally with each other. The front grille is bent according to the slope angle with respect to the floor grid.
Bei einer besonders vorteilhaften Ausführungsform sind das Bodengitter und das Frontgitter getrennte Bauteile, die längs eines Randes gelenkig miteinander verbunden sind. Die getrennten Bauteile können sehr platzsparend zum Einbauort transportiert werden, da sie für den Transport aufeinandergelegt werden können. Am Einbauort lässt sich das Frontgitter in einfacher Weise in die gewünschte Lage relativ zum Bodengitter einstellen. Infolge der gelenkigen Verbindung zwischen dem Bodengitter und dem Frontgitter kann jeder Böschungswinkel problemlos am Einbauort eingestellt werden. Das Bodengitter und das Frontgitter sind ausreichend biegesteif ausgebildet, so dass unzulässige Verformungen in der Einbaulage nicht auftreten.In a particularly advantageous embodiment, the floor grid and the front grille are separate components which are hinged together along one edge. The separate components can be transported very space-saving to the installation site, since they can be stacked for transport. At the installation site, the front grille can be easily adjusted to the desired position relative to the floor grille. As a result of the articulated connection between the floor grid and the front grille, each slope angle can be easily adjusted at the installation site. The floor grid and the front grille are sufficiently rigid, so that inadmissible deformations in the installation position do not occur.
Das Bodengitter oder das Frontgitter sind an ihren benachbarten Rändern mit Einhängehaken versehen. Sie umgreifen einen endseitigen Gitterdraht/stab des Frontgitters oder des Bodengitters. Dadurch lassen sich das Bodengitter und das Frontgitter durch einen einfachen Einhakvorgang gelenkig miteinander verbinden. Selbst wenn diese Gitter lang sind, kann dieser Einhakvorgang von einer Person durchgeführt werden.The floor grille or the front grille are provided with hooks on their adjacent edges. They embrace a terminal grid wire / rod of the front grille or the floor grille. As a result, the floor grid and the front grille can be connected to one another by a simple hooking operation. Even if these grids are long, this hooking operation can be performed by one person.
Vorteilhaft sind das Bodengitter und auch das Frontgitter an ihrer einen Schmalseite mit weiteren Haken versehen, so dass ein weiteres Bodengitter und ein weiteres Frontgitter angeschlossen werden können. Diese weiteren Haken umgreifen wiederum einen endseitigen Gitterdraht/stab des weiteren benachbarten Bodengitters bzw. Frontgitters.Advantageously, the floor grid and the front grille are provided on one narrow side with further hooks, so that a further floor grid and another front grille can be connected. These further hooks in turn encompass an end grid wire / bar of the further adjacent floor grid or front grid.
Es ist von Vorteil, wenn das Bodengitter und das Frontgitter unterschiedlich große Maschenöffnungen aufweisen. Durch Wahl der entsprechenden Maschenöffnungen kann den Einbaugegebenheiten Rechnung getragen werden.It is advantageous if the bottom grid and the front grid have different sized mesh openings. By choosing the appropriate mesh openings, the installation conditions can be taken into account.
So können die Maschenöffnungen des Frontgitters kleiner sein als die Maschenöffnungen des Bodengitters.Thus, the mesh openings of the front grid can be smaller than the mesh openings of the floor grid.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention will become apparent from the other claims, the description and the drawings.

Die Enden der Gitterdrähte 4' sind auf den endseitigen Gitterdrähten 3' befestigt und stehen nicht über diese vor.The grid wires 3 'have at their one end the hook 6', via which an adjacent front grille can be connected. The grid wires 4 ', however, are formed without hooks. The ends of the grid wires 4 'are mounted on the end grid wires 3' and do not project beyond them.
Zur Bildung der Einrichtung wird das Frontgitter 2 mit seinem einen endseitigen Gitterdraht 3' in die Haken 7 der einen Längsseite des Bodengitters 1 eingehängt. Aufgrund der gelenkigen Verbindung von Bodengitter 1 und Frontgitter 2 lässt sich jeder gewünschte Böschungswinkel sehr einfach einstellen. Es ist nur noch notwendig, die Stützelemente 4 (
In die vom Frontgitter 2 entfernt liegenden Haken 7 lässt sich das Geogitter 16 in der beschriebenen Weise problemlos einhängen, so dass es formschlüssig mit dem Bodengitter 1 verbunden ist.
Bei den beschriebenen Ausführungsformen kann in die an der freien Längsseite des Bodengitters 1 befindlichen Haken 7 außer dem Geogitter 16 auch noch ein nächstes Bodengitter eingehängt werden. Das Bodengitter 1 lässt sich auf diese Weise sehr einfach verlängern, wenn dies die Einbaugegebenheiten erfordern.In the described embodiments, in addition to the
Die zweiteilige Ausbildung und gelenkige Verbindung von Bodengitter 1 und Frontgitter 2 macht es in einfacher Weise möglich, die Einrichtung optimal an die Einbaugegebenheiten anzupassen. So können, wie das Ausführungsbeispiel nach den
Das Bodengitter 1 hingegen kann weitmaschig ausgebildet sein, d.h. die Maschenöffnungen 5 haben beispielsweise eine Größe von 10 auf 10 cm, von 10 auf 20 cm oder gar 20 auf 20 cm. Dabei können für das Boden- und das Frontgitter 1, 2 auch unterschiedliche Materialien eingesetzt werden. Die zweiteilige Ausbildung der Einrichtung hat außerdem den Vorteil, dass die Einrichtung erst am Einbauort zusammengesetzt wird. Die Gitter 1, 2 können dadurch einfach und platzsparend transportiert werden. Da das Boden- und das Frontgitter 1, 2 über die Haken 7 gelenkig miteinander verbunden werden, ist eine einfache Koppelung der beiden Gitter 1, 2 möglich. Das Frontgitter 2 lässt sich auch bei größeren Längen von nur einer Person einfach in die Haken 7 des Bodengitters 1 einhängen.The
Bei der Ausführungsform gemäß den
Die zum Einhängen des Frontgitters 2 vorgesehenen Haken 7 des Bodengitters 1 sind so geformt, dass das Frontgitter 1 nicht ohne weiteres aus den Haken 7 herausrutschen kann. Zu diesem Zweck sind die freien Enden der Haken 7 verhältnismäßig lang ausgebildet, so dass der endseitige Gitterdraht 3' des Frontgitters 2 um ein größeres Maß verschoben werden müsste, um von den Haken 7 des Bodengitters 1 freizukommen. Sobald die Stützelemente 4 in das Boden- und in das Frontgitter 1, 2 eingehängt sind, sind die beiden Gitter 1, 2 sicher miteinander so verbunden, dass sie sich nicht unbeabsichtigt voneinander lösen können.The measures provided for attaching the
