Definitions

  • the invention relates to a drainage unit with the features of the preamble of claim 1.
  • a drainage unit is, for example, from DE 10 2009 044 412 A1 famous.
  • trench systems have trench bodies whose boundary walls are water-permeable.
  • the stability of the trench system is determined by the columns or pylons arranged inside the trench body, which connect the base plates of the trench body to one another.
  • trench bodies are stacked one on top of the other in order to achieve a sufficient drainage depth. It is important that the trench bodies stacked on top of each other give the system sufficient stability overall.
  • Trench units with stackable and pluggable trench bodies are also available EP 2 495 373 A2 , WO 2011/004508 A1 and U.S. 2015/017384 A1 famous.
  • the invention is based on the object of specifying a trench unit that is sufficiently stable even with larger dimensions of the trench unit, i.e. with at least two trench bodies stacked one on top of the other.
  • the object is achieved by a trench unit with at least two trench bodies, each of which has an upper base plate, a lower base plate and hollow columns.
  • the hollow columns are arranged vertically between the base plates and form column openings in the base plates.
  • the lower base plate of one trench body and the upper base plate of the other trench body rest on one another in such a way that the column openings of the two base plates lying on them are arranged concentrically.
  • the trench bodies are connected by at least one insert having a bearing surface and two male profiles arranged on either side of the bearing surface and connected thereto.
  • the support surface is arranged between the overlying base plates.
  • the plug-in profiles are inserted into two concentrically arranged column openings in the base plates.
  • the invention has the advantage that the stability of the trench unit is improved. This makes it possible to stack almost any number of trench bodies on top of one another without the risk of the trench bodies slipping relative to one another.
  • the invention provides anti-slip protection so that the transverse forces acting on the trench unit are safely dissipated without the trench body slipping. It is thus possible to vary the height of the trench unit in order to increase the drainage capacity of the trench unit.
  • the plug-in profiles can thus be plugged into the column openings in a form-fitting manner.
  • the plug-in profiles can be designed at least partially symmetrically, in particular completely symmetrically. On the one hand, this simplifies production. On the other hand, the plug-in profiles can be used in both directions. Incorrect installation of the plug-in profile is thus practically impossible, since both sides of the insert fit into both the upper and the lower base plate.
  • the plug-in profiles each have a plurality of plug-in blocks.
  • the plug blocks can be oriented in different directions in order to achieve a corresponding support effect in these directions.
  • the arrangement of the plug-in blocks is arbitrary, as long as the result is a plug-in profile that can be positively connected to the concentrically arranged column openings of the base plates.
  • the plug blocks are preferably arranged in a cross shape. This increases the stability of the trench unit in the main load directions.
  • the plug blocks can each have reinforcing ribs which are arranged in a cross shape.

  • the plug-in profiles each have contact surfaces that adjoin the inside of the hollow columns to form the form-fitting connection, the contour of the contact surfaces being adapted to the contour of the inside of the hollow columns. In this way, area forces can be transmitted to the hollow columns via the inserts, which improves the application of force and thus the stability of the trench unit.
  • the contour of the contact surfaces is wave-shaped. It has been shown that this achieves a particularly stable hold with a correspondingly wavy inner profile of the hollow columns.

  • the plug-in blocks are preferably connected to the ring and thus fixed in the radial direction.
  • the plug blocks can be connected to one another both in the radial and in the axial direction of the insert piece, which increases the stability of the insert piece.
  • a plurality of inserts are connected to one another, with the position of the inserts corresponding to the position of the column openings.
  • the insert piece for the trench unit with at least two trench bodies is also disclosed on its own, i.e. independently of the trench unit.
  • a trench unit with a trench body is disclosed and claimed, in which a further insert piece covers at least one column opening in the upper base plate to form a continuously accessible surface.
  • the above-mentioned insert piece is not provided for connecting two trench bodies, but for covering a column opening. Accordingly, the top of the insert is flat to allow unimpeded access to the top of the trench body.
  • the insert piece has only a single male profile, which is inserted into the column opening and has cross-shaped arranged male blocks, which are aligned with main ribs of the upper base plate in at least 2 mutually perpendicular directions.
  • the aligned arrangement has the advantage that forces introduced into the reinforcing ribs are optimally introduced into the main ribs of the upper base plate. The same applies vice versa. The stability of the trench body is thus improved by the insert.

Description

Die Erfindung betrifft eine Rigoleneinheit mit den Merkmalen des Oberbegriffs des Anspruchs 1. Eine derartige Rigoleneinheit ist beispielsweise aus DE 10 2009 044 412 A1 bekannt.The invention relates to a drainage unit with the features of the preamble of claim 1. Such a drainage unit is, for example, from DE 10 2009 044 412 A1 famous.

Es ist bekannt, Rigolensysteme zum Entwässern von Oberflächen einzusetzen, wobei das abzuführende Wasser durch die Oberfläche in das Rigolensystem gelangt und von dort abgeführt wird, beispielsweise in eine Kläranlage. Dazu weisen Rigolensysteme Rigolenkörper auf, deren Begrenzungswände wasserdurchlässig sind. Die Stabilität der Rigolensysteme wird durch die im Inneren der Rigolenkörper angeordneten Säulen bzw. Pylonen bestimmt, die die Grundplatten des Rigolenkörpers miteinander verbinden. In der Praxis werden Rigolenkörper übereinandergestapelt, um eine ausreichende Entwässerungstiefe zu erreichen. Dabei kommt es darauf an, dass die übereinander gestapelten Rigolenkörper dem System insgesamt eine ausreichende Stabilität verleihen.It is known to use infiltration systems for draining surfaces, with the water to be discharged passing through the surface into the infiltration system and being discharged from there, for example into a sewage treatment plant. For this purpose, trench systems have trench bodies whose boundary walls are water-permeable. The stability of the trench system is determined by the columns or pylons arranged inside the trench body, which connect the base plates of the trench body to one another. In practice, trench bodies are stacked one on top of the other in order to achieve a sufficient drainage depth. It is important that the trench bodies stacked on top of each other give the system sufficient stability overall.

Rigoleneinheiten mit stapelbaren und steckverbindbaren Rigolenkörpern sind außerdem aus EP 2 495 373 A2 , WO 2011/004508 A1 und US 2015/017384 A1 bekannt.Trench units with stackable and pluggable trench bodies are also available EP 2 495 373 A2 , WO 2011/004508 A1 and U.S. 2015/017384 A1 famous.

Der Erfindung liegt die Aufgabe zu Grunde, eine Rigoleneinheit anzugeben, die auch bei größeren Dimensionen der Rigoleneinheit, d.h. bei wenigstens zwei übereinander gestapelten Rigolenkörpern, ausreichend stabil ist.The invention is based on the object of specifying a trench unit that is sufficiently stable even with larger dimensions of the trench unit, i.e. with at least two trench bodies stacked one on top of the other.

Erfindungsgemäß wird diese Aufgabe durch die Rigoleneinheit nach Anspruch 1 gelöst.According to the invention, this object is achieved by the trench unit according to claim 1.

Insbesondere wird die Aufgabe durch eine Rigoleneinheit mit wenigstens zwei Rigolenkörpern gelöst, die jeweils eine obere Grundplatte, eine untere Grundplatte und Hohlsäulen aufweisen. Die Hohlsäulen sind zwischen den Grundplatten senkrecht angeordnet und bilden Säulenöffnungen in den Grundplatten. Die untere Grundplatte des einen Rigolenkörpers und die obere Grundplatte des anderen Rigolenkörpers liegen derart aufeinander auf, dass die Säulenöffnungen der beiden aufliegenden Grundplatten konzentrisch angeordnet sind. Die Rigolenkörper sind durch wenigstens ein Einsatzstück verbunden, das eine Auflagefläche und zwei Einsteckprofile aufweist, die auf beiden Seiten der Auflagefläche angeordnet und mit dieser verbunden sind. Die Auflagefläche ist zwischen den aufliegenden Grundplatten angeordnet. Die Einsteckprofile sind in zwei konzentrisch angeordnete Säulenöffnungen der aufliegenden Grundplatten eingesteckt.In particular, the object is achieved by a trench unit with at least two trench bodies, each of which has an upper base plate, a lower base plate and hollow columns. The hollow columns are arranged vertically between the base plates and form column openings in the base plates. The lower base plate of one trench body and the upper base plate of the other trench body rest on one another in such a way that the column openings of the two base plates lying on them are arranged concentrically. The trench bodies are connected by at least one insert having a bearing surface and two male profiles arranged on either side of the bearing surface and connected thereto. The support surface is arranged between the overlying base plates. The plug-in profiles are inserted into two concentrically arranged column openings in the base plates.

Die Erfindung hat den Vorteil, dass die Stabilität der Rigoleneinheit verbessert wird. Damit ist es möglich, eine nahezu beliebige Anzahl von Rigolenkörper an übereinander zu stapeln, ohne dass die Gefahr besteht, dass die Rigolenkörper relativ zueinander verrutschen. Die Erfindung bildet eine Verrutschsicherung, sodass die auf die Rigoleneinheit wirkenden Querkräfte sicher abgeleitet werden, ohne dass die Rigolenkörper verrutschen. Es ist damit möglich, die Höhe der Rigoleneinheit zu variieren, um die Entwässerungsleistung der Rigoleneinheit zu erhöhen.The invention has the advantage that the stability of the trench unit is improved. This makes it possible to stack almost any number of trench bodies on top of one another without the risk of the trench bodies slipping relative to one another. The invention provides anti-slip protection so that the transverse forces acting on the trench unit are safely dissipated without the trench body slipping. It is thus possible to vary the height of the trench unit in order to increase the drainage capacity of the trench unit.

Bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Preferred embodiments of the invention are given in the subclaims.

So können die Einsteckprofile in die Säulenöffnungen formschlüssig eingesteckt sein.The plug-in profiles can thus be plugged into the column openings in a form-fitting manner.

Die Einsteckprofile können zumindest teilweise symmetrisch, insbesondere vollständig symmetrisch ausgebildet sein. Dadurch wird einerseits die Herstellung vereinfacht. Andererseits können die Einsteckprofile in beiden Richtungen verwendet werden. Ein fehlerhafter Einbau der Einsteckprofile ist damit praktisch ausgeschlossen, da beide Seiten des Einsatzstückes sowohl in die obere als auch in die untere Grundplatte passen.The plug-in profiles can be designed at least partially symmetrically, in particular completely symmetrically. On the one hand, this simplifies production. On the other hand, the plug-in profiles can be used in both directions. Incorrect installation of the plug-in profile is thus practically impossible, since both sides of the insert fit into both the upper and the lower base plate.

Bei einer bevorzugten Ausführungsform weisen die Einsteckprofile jeweils mehrere Steckblöcke auf. Die Steckblöcke können in unterschiedlichen Richtungen orientiert sein, um eine entsprechende Stützwirkung in diesen Richtungen zu erzielen. Die Anordnung der Steckblöcke ist beliebig, solange sich ein Einsteckprofil ergibt, das formschlüssig mit den konzentrisch angeordneten Säulenöffnungen der aufliegenden Grundplatten verbunden werden kann.In a preferred embodiment, the plug-in profiles each have a plurality of plug-in blocks. The plug blocks can be oriented in different directions in order to achieve a corresponding support effect in these directions. The arrangement of the plug-in blocks is arbitrary, as long as the result is a plug-in profile that can be positively connected to the concentrically arranged column openings of the base plates.

Vorzugsweise sind die Steckblöcke kreuzförmig angeordnet. Damit wird die Stabilität der Rigoleneinheit in den Hauptbelastungsrichtungen erhöht.The plug blocks are preferably arranged in a cross shape. This increases the stability of the trench unit in the main load directions.

Die Steckblöcke können jeweils Verstärkungsrippen aufweisen, die kreuzförmig angeordnet sind. Durch die Kombination mit den kreuzförmig angeordneten Steckblöcken ergibt sich eine doppelt kreuzförmige Konfiguration, wodurch die Stabilität der Rigoleneinheit weiter erhöht wird.The plug blocks can each have reinforcing ribs which are arranged in a cross shape. The combination with the cross-shaped plug-in blocks results in a double cross-shaped configuration, which further increases the stability of the trench unit.

Bei einer bevorzugten Ausführung weisen die Einsteckprofile jeweils Anlageflächen auf, die an die Innenseite der Hohlsäulen zur Bildung der formschlüssigen Verbindung angrenzen, wobei die Kontur der Anlageflächen an die Kontur der Innenseite der Hohlsäulen angepasst ist. Auf diese Weise können über die Einsatzstücke Flächenkräfte auf die Hohlsäulen übertragen werden, wodurch die Krafteinleitung und damit die Stabilität der Rigoleneinheit verbessert wird.In a preferred embodiment, the plug-in profiles each have contact surfaces that adjoin the inside of the hollow columns to form the form-fitting connection, the contour of the contact surfaces being adapted to the contour of the inside of the hollow columns. In this way, area forces can be transmitted to the hollow columns via the inserts, which improves the application of force and thus the stability of the trench unit.

Vorzugsweise ist die Kontur der Anlageflächen wellenförmig ausgebildet. Es hat sich gezeigt, dass dadurch ein besonders stabiler Halt bei entsprechend wellenförmigen Innenprofil der Hohlsäulen erreicht wird.Preferably, the contour of the contact surfaces is wave-shaped. It has been shown that this achieves a particularly stable hold with a correspondingly wavy inner profile of the hollow columns.

Die Auflagefläche des Einsatzstückes kann im Wesentlichen in der Form eines Ringes ausgebildet sein, dessen Außendurchmesser größer als der Durchmesser der Säulenöffnungen ist. Diese Ausgestaltung hat den Vorteil, dass das Einsatzstück durch die Gewichtskraft des oberen Rigolenkörper fixiert wird.The bearing surface of the insert can be essentially in the form of a ring, the outside diameter of which is larger than the diameter of the column openings. This configuration has the advantage that the insert is fixed by the weight of the upper trench body.

Vorzugsweise sind die Steckblöcke mit dem Ring verbunden und damit in radialer Richtung fixiert. Zusätzlich können die Steckblöcke miteinander verbunden sein und zwar sowohl in radialer als auch in axialer Richtung des Einsatzstückes, wodurch die Stabilität des Einsatzstückes erhöht wird.The plug-in blocks are preferably connected to the ring and thus fixed in the radial direction. In addition, the plug blocks can be connected to one another both in the radial and in the axial direction of the insert piece, which increases the stability of the insert piece.

Bei einer weiteren bevorzugten Ausführung sind mehrere Einsatzstücke miteinander verbunden, wobei die Position der Einsatzstücke der Lage der Säulenöffnungen entspricht. Diese Ausführung verbessert die Handhabbarkeit der Einsatzstücke, weil mehrere Einzelstücke gleichzeitig mit verschiedenen Säulenöffnungen verbunden werden können. Es ist also nicht notwendig, die einzelnen Einsatzstücke auszurichten und mit einzelnen Säulenöffnungen gesondert zu verbinden.In a further preferred embodiment, a plurality of inserts are connected to one another, with the position of the inserts corresponding to the position of the column openings. This design improves the handling of the inserts because several individual pieces can be connected to different column openings at the same time. It is therefore not necessary to align the individual inserts and connect them separately to individual column openings.

Im Rahmen der Erfindung wird das Einsatzstück für die Rigoleneinheit mit wenigstens zwei Rigolenkörper auch für sich genommen, d.h. unabhängig von der Rigoleneinheit offenbart. Außerdem wird im Rahmen einer bevorzugten Ausführungsform der Erfindung eine Rigoleneinheit mit einem Rigolenkörper offenbart und beansprucht, bei dem ein weiteres Einsatzstück wenigstens eine Säulenöffnung in der oberen Grundplatte zur Bildung einer durchgängig begehbaren Fläche abdeckt.Within the scope of the invention, the insert piece for the trench unit with at least two trench bodies is also disclosed on its own, i.e. independently of the trench unit. In addition, within the scope of a preferred embodiment of the invention, a trench unit with a trench body is disclosed and claimed, in which a further insert piece covers at least one column opening in the upper base plate to form a continuously accessible surface.

Im Unterschied zur dem Einsatzstück mit den auf beiden Seiten der Auflagefläche angeordneten Einsteckprofile ist das vorstehend genannte Einsatzstück nicht zum Verbinden zweier Rigolenkörper vorgesehen, sondern zum Abdecken einer Säulenöffnung. Dementsprechend ist die Oberseite des Einsatzstückes flach, um eine ungehinderte Begehung der Oberseite des Rigolenkörper zu ermöglichen. Dazu weist das Einsatzstück nur ein einziges Einsteckprofil auf, das in die Säulenöffnung eingesteckt ist und kreuzförmig angeordnete Steckblöcke aufweist, die mit Hauptrippen der oberen Grundplatte in wenigstens 2 senkrecht zu einander verlaufenden Richtungen fluchten.In contrast to the insert piece with the plug-in profiles arranged on both sides of the support surface, the above-mentioned insert piece is not provided for connecting two trench bodies, but for covering a column opening. Accordingly, the top of the insert is flat to allow unimpeded access to the top of the trench body. For this purpose, the insert piece has only a single male profile, which is inserted into the column opening and has cross-shaped arranged male blocks, which are aligned with main ribs of the upper base plate in at least 2 mutually perpendicular directions.

Die fluchtende Anordnung hat den Vorteil, dass in die Verstärkungsrippen eingeleitete Kräfte optimal in die Hauptrippen der oberen Grundplatte eingeleitet werden. Umgekehrt gilt dasselbe. Damit wird die Stabilität des Rigolenkörpers durch das Einsatzstück verbessert. Die vorstehend genannte fluchtende Anordnung der Steckblöcke wird auch im Zusammenhang mit dem Einsatzstück zur Verbindung zweier Rigolenkörper offenbart und beansprucht.The aligned arrangement has the advantage that forces introduced into the reinforcing ribs are optimally introduced into the main ribs of the upper base plate. The same applies vice versa. The stability of the trench body is thus improved by the insert. The aforementioned aligned Arrangement of the plug-in blocks is also disclosed and claimed in connection with the insert for connecting two trench bodies.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Bezug auf die beigefügten Figuren mit weiteren Einzelheiten näher erläutert.The invention is explained in more detail below using exemplary embodiments with reference to the accompanying figures.

Die in den Figuren 1, 2 dargestellten Grundplatten 11, 12 bilden die Basiselemente eines Rigolenkörpers. Bei dem Rigolenkörper handelt es sich um einen kastenförmigen Körper mit gitterartigen Begrenzungsflächen, durch die Wasser in den Rigolenkörper fließen kann. Der Rigolenkörper kann in bekannter Weise mit einem Geotextil umwickelt werden, um das Eindringen von Sedimenten in das Rigolensystem zu verhindern.The in the Figures 1, 2 illustrated base plates 11, 12 form the basic elements of a trench body. The trench body is a box-shaped body with grid-like boundary surfaces through which water can flow into the trench body. The trench body can be wrapped in a known manner with a geotextile in order to prevent the penetration of sediments into the trench system.

Ein aus derartigen Rigolenkörpern zusammengesetztes Rigolensystem dient zum einen als Blockspeicher für Niederschlagswasser und zum anderen als Blockversickerung von Niederschlagswasser. Die Basis dieses Systems sind die Figuren 1, 2 dargestellten, identischen Grundplatten, die auf unterschiedliche Weise miteinander kombiniert werden können. Die obere Grundplatte 11 ist im verlegten Zustand des Rigolensystems oben und die untere Grundplatte 12 unten angeordnet. Die Grundplatten weisen jeweils Hohlsäulen 13a, 13b auf, die sich senkrecht zu den Grundplatten 11, 12 erstrecken und mit diesen verbunden sind. Die Hohlsäulen 13a, 13b bilden Abstandshalter, die den Abstand der Grundplatten 11, 12 zueinander festlegen. Dazu werden die Hohlsäulen 13a, 13b mit ihren freien Enden aufeinander aufgesteckt. Die Hohlsäulen 13a, 13b, auch Pylonen genannt, sind konusartig ausgebildet, wobei die kleinere Querschnittsöffnung das freie Ende und die größere Querschnittsöffnung das mit der jeweiligen Grundplatte 11, 12 verbundene Ende der jeweiligen Hohlsäule 13a, 13b bilden. Die Hohlsäulen 13a, 13b bilden Säulenöffnungen 14 in der jeweiligen Grundplatte 11, 12, wie in Fig. 2 gut zu sehen.A trench system composed of such trench bodies serves on the one hand as block storage for rainwater and on the other as block infiltration of rainwater. The basis of this system are the Figures 1, 2 illustrated, identical base plates, which can be combined in different ways. In the laid state of the trench system, the upper base plate 11 is arranged at the top and the lower base plate 12 is arranged at the bottom. The base plates each have hollow columns 13a, 13b which extend perpendicularly to the base plates 11, 12 and are connected to them. The hollow columns 13a, 13b form spacers which determine the spacing of the base plates 11, 12 from one another. For this purpose, the hollow columns 13a, 13b are plugged onto one another with their free ends. The hollow columns 13a, 13b, also called pylons, are cone-shaped, with the smaller cross-sectional opening forming the free end and the larger cross-sectional opening forming the end of the respective hollow column 13a, 13b connected to the respective base plate 11, 12. The hollow columns 13a, 13b form column openings 14 in the respective base plate 11, 12, as in FIG 2 good to see.

Um die Höhe des Rigolensystem zur vergrößern, ist es üblich, dass mehrere Lagen aus Rigolenkörpern 10a, 10b an aufeinander gestapelt werden (s. Fig. 5). Dabei kommt eine untere Grundplatte 12 des oberen Rigolenkörpers 10a mit einer oberen Grundplatte 11 des darunterliegenden Rigolenkörpers 10b in Anlage.In order to increase the height of the trench system, it is common for several layers of trench bodies 10a, 10b to be stacked on top of each other (see Fig. figure 5 ). A lower base plate 12 of the upper trench body 10a comes into contact with an upper base plate 11 of the underlying trench body 10b.

An dieser Stelle setzt die Erfindung ein, die, wie anhand des Ausführungsbeispiels gemäß Fig. 3 gezeigt, die Verbindung zwischen den übereinandergestapelten Rigolenkörpern 10a, 10b verbessert.This is where the invention comes in, which, as shown in the exemplary embodiment 3 shown, improves the connection between the stacked trench bodies 10a, 10b.

Dazu ist ein Einsatzstück 15 vorgesehen, das in den Figuren 3, 4 dargestellt ist. Das Einsatzstück 15 weist eine Auflagefläche 16 und zwei Einsteckprofile 17a, 17b auf. Wie in den Figuren 3 und 5 gut zu erkennen, sind die Einsteckprofile 17a, 17b auf beiden Seiten der Auflagefläche 16 angeordnet. Mit anderen Worten befindet sich die Auflagefläche 16 zwischen dem oberen Einsteckprofil 17a und dem unteren Einsteckprofil 17b. Die Einsteckprofile 17a, 17b sind dazu ausgebildet, die auftretenden Horizontallasten in den (Haupt)richtungen parallel zu den Grundflächen der Grundkörpern 11, 12 aufzunehmen. Dazu weisen sie eine kreuzförmige Struktur mit Rippen auf, die den entsprechenden Rippen der Grundplatten 11, 12 folgt. Die Auflagefläche 16 erstreckt sich in Umfangsrichtung zwischen den Einsteckprofilen 17a, 17b. Außerdem ragt die Auflagefläche 16 radial über die Einsteckprofile 17a, 17b vor. Dadurch ist es möglich, dass die Auflagefläche 16 auf der Oberseite der jeweiligen Grundplatte 11, 12 aufliegt und die durch den oberen Rigolenkörper durch dessen Gewicht fixiert wird.For this purpose, an insert 15 is provided in the Figures 3, 4 is shown. The insert 15 has a bearing surface 16 and two plug-in profiles 17a, 17b. As in the Figures 3 and 5 clearly visible, the plug-in profiles 17a, 17b are arranged on both sides of the bearing surface 16. In other words the bearing surface 16 is located between the upper plug-in profile 17a and the lower plug-in profile 17b. The plug-in profiles 17a, 17b are designed to absorb the horizontal loads that occur in the (main) directions parallel to the base surfaces of the base bodies 11, 12. For this purpose they have a cruciform structure with ribs which follows the corresponding ribs of the base plates 11,12. The bearing surface 16 extends in the circumferential direction between the plug-in profiles 17a, 17b. In addition, the bearing surface 16 protrudes radially beyond the plug-in profiles 17a, 17b. This makes it possible for the bearing surface 16 to rest on the upper side of the respective base plate 11, 12 and to be fixed by the weight of the upper trench body.

Die Einsteckprofile 17a, 17b sind symmetrisch ausgebildet und weisen jeweils mehrere Steckblöcke 18 auf. Die Steckblöcke 18 dienen dazu, die formschlüssige Verbindung zu den Hohlsäulen 13a, 13b bzw. Säulenöffnungen 14 herzustellen. Die Steckblöcke 18 weisen jeweils Wände 23 auf, die die Steckblöcke 18 seitlich begrenzen. Wie in Fig. 4 dargestellt, sind die Steckblöcke 18 kreuzförmig angeordnet, wobei vier Steckblöcke 18 um einen mittigen Steckblock 18 herum angeordnet sind. Andere Anordnungen der Steckblöcke 18 sind möglich. Die Steckblöcke 18 sind im wesentlichen quaderförmig ausgebildet. Andere Geometrie der einzelnen Steckblöcke 18 sind möglich.The plug-in profiles 17a, 17b are symmetrical and each have a plurality of plug-in blocks 18. The plug-in blocks 18 serve to establish the positive connection to the hollow columns 13a, 13b or column openings 14. The plug-in blocks 18 each have walls 23 which delimit the plug-in blocks 18 laterally. As in 4 As shown, the sub-blocks 18 are arranged in a cross-shape, with four sub-blocks 18 being arranged around a central sub-block 18 . Other arrangements of the plug blocks 18 are possible. The plug-in blocks 18 are essentially cuboid. Other geometries of the individual plug-in blocks 18 are possible.

Die Stirnflächen der Steckblöcke 18, d.h. die freien Enden der Steckblöcke 18 weisen jeweils eine Anlagefläche 20 auf, die im eingebauten Zustand an der Innenwand bzw. an der Innenseite 21 der jeweiligen Hohlsäule 13a, 13b anliegt (siehe Fig. 5). Konkret sind die Anlageflächen 20 wellenförmig ausgebildet. Auch hier sind andere Geometrie möglich. Vorteilhafterweise erstrecken sich die Anlageflächen 20 über die Steckblöcke 18 hinaus, damit eine Flächenpressung im Bereich zwischen den Anlageflächen 20 und der Innenseiten 21 der Hohlsäulen 13a, 13b verringert werden kann. Auf diese Weise können die auftretenden Horizontalkräfte als Flächenlast anstatt als Linienlast übertragen werden. Durch die Übergabe der horiziontalen Kräfte als Flächenlast anstatt als Linienlast können größere Kräfte übertragen werden.The end faces of the plug-in blocks 18, ie the free ends of the plug-in blocks 18 each have a contact surface 20 which, in the installed state, rests against the inner wall or the inside 21 of the respective hollow column 13a, 13b (see Fig figure 5 ). Specifically, the contact surfaces 20 are formed in a wave shape. Other geometries are also possible here. The contact surfaces 20 advantageously extend beyond the plug-in blocks 18 so that a surface pressure in the area between the contact surfaces 20 and the inner sides 21 of the hollow columns 13a, 13b can be reduced. In this way, the horizontal forces that occur can be transferred as a surface load instead of as a line load. Larger forces can be transmitted by transferring the horizontal forces as a distributed load instead of as a line load.

Zwischen den Wänden 23 der Steckblöcke 18 sind erste und zweite Verstärkungsrippen 19a, 19b kreuzförmig angeordnet.Between the walls 23 of the plug blocks 18, first and second reinforcing ribs 19a, 19b are arranged in a cross shape.

Die Auflagefläche 16 ist bei dem Ausführungsbeispiel gemäß Figuren 3, 4 als Ring 22 ausgebildet, dessen Außendurchmesser etwas größer ist als der Durchmesser der Säulenöffnungen 14. Dadurch wird erreicht, dass die Auflagefläche 16 auf der jeweiligen Grundplatte 11, 12 aufliegen kann, wenn das Einsatzstück 15 in die Öffnung 14 eingesteckt ist. Die ringförmige Auflagefläche 16 kann eine oder mehrere Ausnehmungen aufweisen, um beim Verpacken, z.B. auf einer Pallette, Führungen für Verpackungsbänder bereitzustellen. Die Rippen der Einsteckprofile weisen komplementäre Ausnehmungen bzw Erhöhungen auf, um eine vereinfachte Stapelbarkeit mehrerer Einsatzstücke 15 zu ermöglichen.The bearing surface 16 is in accordance with the embodiment Figures 3, 4 designed as a ring 22 whose outer diameter is slightly larger than the diameter of the column openings 14. This ensures that the bearing surface 16 can rest on the respective base plate 11, 12 when the insert 15 is inserted into the opening 14. The ring-shaped support surface 16 can have one or more recesses in order to provide guides for packaging tapes during packaging, for example on a pallet. The ribs of the plug-in profiles have complementary recesses or elevations in order to make it easier for several insert pieces 15 to be stacked.

Der Innendurchmesser des Rings 22 entspricht in etwa dem Innendurchmesser der Hohlsäulen 13a, 13b.The inner diameter of the ring 22 corresponds approximately to the inner diameter of the hollow columns 13a, 13b.

Wie in Fig. 3 gezeigt, sind vier identische Einsatzstücke 15 zu einem zusammenhängenden Verbund zusammengefasst, wobei die Einsatzstücke 15 durch Stege miteinander verbunden sind. Der Verbund kann einheitlich montiert werden. Die einzelnen Einsatzstücke 15 sind dabei elastisch miteinander verbunden, um eventuelle Toleranzen der Grundkörper als solche bzw. der Grundkörper in der Einbausituation ausgleichen zu können.As in 3 shown, four identical inserts 15 are combined to form a coherent composite, with the inserts 15 being connected to one another by webs. The composite can be mounted uniformly. The individual inserts 15 are elastically connected to one another in order to be able to compensate for any tolerances in the base body as such or the base body in the installation situation.

In Fig. 5 ist gut zu erkennen, dass die untere Grundplatte 12 des oberen Rigolenkörpers 10a mit der oberen Grundplatte 11 des unteren Rigolenkörper 10b verbunden ist. Die Verbindung erfolgt durch das vorstehend beschriebene Einsatzstück 15, das in der Säulenöffnung 14 angeordnet ist. Dabei liegt die Anlagefläche 20 des Steckblocks 18 an der Innenwand 21 der unteren Hohlsäule 13b an. Die beiden Grundplatten 11, 12 sind lagefixiert und können aufgrund des Einsatzstücks 15 nicht verrutschen. Über die Höhe des Einsatzstücks 15 kann der Eingriffsgrad mit den jeweiligen Hohlsäulen 13a, 13b variiert werden, wobei bei zunehmender Höhe der Konizität der Hohlsäulen 13a, 13b Rechnung zu tragen ist.In figure 5 It is easy to see that the lower base plate 12 of the upper trench body 10a is connected to the upper base plate 11 of the lower trench body 10b. The connection is made through the insert piece 15 described above, which is arranged in the column opening 14 . The contact surface 20 of the plug-in block 18 rests against the inner wall 21 of the lower hollow column 13b. The two base plates 11, 12 are fixed in position and cannot slip due to the insert 15. The degree of engagement with the respective hollow columns 13a, 13b can be varied via the height of the insert piece 15, with the conicity of the hollow columns 13a, 13b having to be taken into account as the height increases.

Wie in Fig. 6 dargestellt, werden vor dem Verbinden der Rigolenkörper die Einsatzstücke 15 in die Säulenöffnungen 14 eingesteckt, sodass die Einsteckprofile 17a mit den Säulenöffnungen 14 bzw. den Hohlsäulen 13a in Eingriff kommen (linke Darstellung in Fig. 6). Dann wird eine weitere Grundplatte, im Beispiel gemäß Fig. 6 die untere Grundplatte 12 des oberen Rigolenkörpers 10a auf die die Einsatzstücke 15 aufgesetzt. Dazu werden die Säulenöffnungen 14 der beiden Grundplatten 11, 12 konzentrisch zueinander ausgerichtet. Die Gesamtausrichtung der beiden Grundplatten 11, 12 wird durch die Lage der Einsatzstücke 15 präzise und sicher festgelegt.As in 6 shown, before the trench bodies are connected, the inserts 15 are inserted into the column openings 14, so that the plug-in profiles 17a engage with the column openings 14 or the hollow columns 13a (left-hand illustration in 6 ). Then another base plate, according to the example 6 the lower base plate 12 of the upper trench body 10a on which the inserts 15 are placed. For this purpose, the column openings 14 of the two base plates 11, 12 are aligned concentrically with one another. the The overall alignment of the two base plates 11, 12 is defined precisely and securely by the position of the inserts 15.

In Fig. 7 ist eine Alternative zur dem als Verbindungsstück fungierenden Einsatzstück 15 dargestellt. Bei diesem Einsatzstück 15 handelt es sich um eine Abdeckung, bei der das Einsatzstück 15 nur ein einziges Einsteckprofil 17a mit Steckblöcken 18 auf dessen Unterseite aufweist. Die Seitenwände 23 der Steckblöcke 18 fluchten mit den Hauptrippen 24 der Grundplatte (siehe Fig. 8). Konkret fluchten die Wände 23 in zwei senkrecht zueinander verlaufenden Richtungen, sodass sich eine maximale Stabilität in den Hauptbelastungsrichtungen ergibt. Die Anordnung der Wände 23 ist sowohl bei dem Beispiel gemäß Fig. 7 als auch bei dem Beispiel gemäß Figuren 3 bis 6 möglich.In 7 an alternative to the insert piece 15 acting as a connecting piece is shown. This insert piece 15 is a cover in which the insert piece 15 has only a single plug-in profile 17a with plug-in blocks 18 on its underside. The side walls 23 of the plug-in blocks 18 are flush with the main ribs 24 of the base plate (see Fig 8 ). Specifically, the walls 23 are aligned in two mutually perpendicular directions, resulting in maximum stability in the main load directions. The arrangement of the walls 23 is according to both the example 7 as well as according to the example Figures 3 to 6 possible.

Die fluchtende Anordnung ist in Fig. 8 dargestellt, in die virtuelle Linien entlang der Hauptrippen 24 eingezeichnet sind. Daraus ergibt sich, dass die Wände 23 mit den Hauptrippen 24 in beiden Hauptrichtungen der Grundplatte 11 fluchten.The aligned arrangement is in 8 shown, in which virtual lines along the main ribs 24 are drawn. The result of this is that the walls 23 are aligned with the main ribs 24 in both main directions of the base plate 11 .
