Description

Die Erfindung betrifft eine Vorrichtung zur druckbelastbaren Abdeckung des von einem Baum durchwurzelten Erdreichs mit einem den Baum umgebenden Tragwerk mit Rahmensegmenten, das mit Abstützungsfüßen versehen ist, die in Richtung auf das sie stützende Erdreich verlaufen.The invention relates to a device for pressure-resistant covering of the soil rooted by a tree with a framework surrounding the tree with frame segments, which is provided with support feet that extend in the direction of the supporting soil.

Derartige Vorrichtungen zur befestigten Abdeckung des von einem Baum durchwurzelten Erdreichs dienen dazu, Baumscheiben in Wege- und Platzflächen so auszubilden, daß sie begangen und befahren werden können, ohne das durchwurzelte Erdreich zu verdichten und die Wurzeln dadurch zu schädigen. Hierzu sind Wurzelkammern aus Betonfertigteilen vorbekannt, die mit Boden verfüllt und einer belastbaren Betonplatte mit einer Öffnung für den Baumstamm versehen abgedeckt werden. Die Nachteile liegen in der konstruktiv notwendig massiven Bauweise, die das freie Auswachsen der Baumwurzeln nach allen Richtungen behindert. Ein weiterer Nachteil liegt in der massiven Abdeckung mit einer Stahlbetonplatte, bei der die Durchlässigkeit für Wasser und Luft auch im besten Fall nur auf einige kleine Aussparungen begrenzt bleiben muß.Such devices for the fixed covering of the soil rooted by a tree are used to form tree disks in pathways and squares so that they can be walked on and driven on without compacting the rooted soil and thereby damaging the roots. For this purpose, root chambers made of precast concrete are known, which are filled with soil and covered with a load-bearing concrete slab with an opening for the tree trunk. The disadvantages lie in the solid construction that is necessary in terms of construction, which prevents the tree roots from growing freely in all directions. Another disadvantage is the massive cover with a reinforced concrete slab, in which the permeability to water and air only has to be limited to a few small recesses in the best case.

Aus dem Europapatent E 027 31 55 ist ein Unterflurbaumrost in Profilstahlkonstruktion vorbekannt, der die Nachteile der Wurzelkammern aus Betonfertigteilen vermeidet, der jedoch durch seine statische Abstützkonstruktion den Wurzelballen und das freie Erdreich um den Stammfuß des Baumes so eng umfaßt, daß er nur während der Pflanzarbeit mit dem Baum bzw. Wurzelballen zusammen eingebaut werden kann oder daß alternativ nur sehr junge Bäume mit sehr kleinen Wurzelballen bei eingebautem Unterflurbaumrost nachträglich gepflanzt werden können. Auch ein nachträgliches Verpflanzen bzw. Herausnehmen eines abgestorbenen Baumes ist nicht möglich, ohne die ganze Konstruktion aus dem Boden auszugraben und beim Wiederbepflanzen neu einzubauen. Ein weiterer Nachteil besteht darin, daß der vorbekannte Unterflurbaumrost auf Bäume mit großen Wurzelballen nicht angepaßt bzw. nicht angewendet werden kann, weil bei Vergrößerung des abstützungsfreien Innenraumes, der für das Einsetzen eines größeren Wurzelballens notwendig wäre, sich gleichzeitig die nicht belastbare Baumscheibenoberfläche vergrößert und damit dem Verdichtungsschutz entzogen wird.From the European patent E 027 31 55 an underfloor grate in profile steel construction is known, which avoids the disadvantages of the root chambers made of prefabricated concrete parts, but which, due to its static support construction, encompasses the root ball and the free soil around the base of the tree so closely that it can only be used during planting can be installed together with the tree or root ball or that alternatively only very young trees with very small root balls when installed Underfloor grate can be planted subsequently. It is also not possible to transplant or remove a dead tree without digging the whole structure out of the ground and reinstalling it when replanted. Another disadvantage is that the previously known underfloor grate cannot be adapted or used on trees with large root balls, because when the support-free interior space that would be necessary for the insertion of a larger root ball is enlarged, the non-resilient tree disc surface increases and thus is removed from the compression protection.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art zu schaffen, die es ermöglicht, den druckgeschützten Wurzelraum durch das Haupttragwerk des Unterflurbaumrostes herzustellen und danach zu beliebiger Zeit Bäume mit beliebig großen Wurzelballen einzupflanzen oder zu verpflanzen, um dann nach erfolgtem Pflanzvorgang den druckschützenden Baumrostbereich, der über dem Wurzelballen liegen muß, so aufzubringen, daß Belastungsdruck durch Begehen und Befahren gleichwohl unter den Wurzelraum bzw. Wurzelballen in das nicht durchwurzelte Erdreich abgeleitet wird.The object of the present invention is therefore to provide a device of the type mentioned at the outset, which makes it possible to produce the pressure-protected root space through the main supporting structure of the underfloor grating and then to plant or transplant trees with root balls of any size at any time, and then after the planting process has taken place to apply the pressure-protecting tree grate area, which must lie above the root ball, in such a way that the pressure of loading through walking and driving is derived under the root area or root ball into the non-rooted soil.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Tragwerk einen äußeren Tragrostrahmen und einen diesem konzentrisch verlaufenden inneren Tragrostrahmen aufweist. Dies hat den Vorteil, daß das Raumtragwerk, das den Wurzelraum des Baumes umfaßt und die Auflast auf der Baumrostfläche in das Erdreich unter dem Wurzelraum ableitet, aus zwei Funktionsteilen besteht. Dabei wird das ringförmige Tragwerk fest eingebaut, das an seiner Oberseite den äußeren Tragrostrahmen trägt und das über Abstützfüße die Kräfte in das Erdreich unterhalb des durchwurzelten Erdreiches ableitet. Ein konzentrisch zum äußeren Tragrostrahmen verlaufender innerer Tragrostrahmen kann als zweiter Funktionsteil unabhängig ein- und ausgebaut werden und stützt sich ebenfalls auf den Abstützungsfüßen ab, so daß er in gleicher Weise belastbar ist wie der äußere Tragrostrahmen.This object is achieved in that the structure has an outer support frame and a concentric inner support frame. This has the advantage that the space structure, which includes the root space of the tree and the load on the tree grate surface in the soil under the root space, consists of two functional parts. The ring-shaped structure is firmly installed, which carries the outer support frame on its top and over Support feet divert the forces into the soil below the rooted soil. An inner support frame that runs concentrically to the outer support frame can be installed and removed independently as a second functional part and is also supported on the support feet, so that it can be loaded in the same way as the outer support frame.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausführlichen Beschreibung mit den beigefügten Zeichnungen, in denen eine bevorzugte Ausführungsform der Erfindung beispielsweise veranschaulicht ist.Further details of the invention will become apparent from the following detailed description with the accompanying drawings, in which a preferred embodiment of the invention is illustrated for example.

Eine erfindungsgemäße Vorrichtung besteht im wesentlichen aus einem Tragwerk 1, welches einen zu umschließenden freien Raum 2 bildet, dessen obere Öffnung 3 von einem äußeren Tragrostrahmen 4 umschlossen wird und in den ein innerer Tragrostrahmen 15 dann eingesetzt wird, wenn das Tragwerk 1 standfest in eine Baumgrube 5 eingebaut ist, die Baumgrube 5 mit Pflanzerde 6 verfüllt und der Baum 7 mit seinem Wurzelballen 8 gepfanzt ist.A device according to the invention essentially consists of a supporting structure 1, which forms a free space 2 to be enclosed, the upper opening 3 of which is enclosed by an outer supporting frame 4 and into which an inner supporting frame 15 is inserted when the supporting structure 1 is stable in a tree pit 5 is installed, the tree pit 5 is filled with planting soil 6 and the tree 7 is planted with its root ball 8.

Das Tragwerk 1 trägt den im wesentlichen horizontal verlaufenden ringförmigen äußeren Tragrostrahmen 4, der mit nach unten weisenden Abstützungsfüßen 9 verbunden ist. Die Abstützungsfüße 9 sind mit ihren unteren Enden 10 auf Fußschienen 11 befestigt. Die Fußschienen 11 verlängern sich in zentralen Richtungen über Aufnahmen der Abstützungsfüße 9 in Richtung auf eine Mittelachse des Tragwerkes 1 bzw. des inneren freien Raumes 2 und tragen an ihren inneren Enden 12 je eine Aufnahmevorrichtung 13 für einen Abstützungsstab 14 zur Abstützung des inneren Tragrostrahmens 15. Jede Fußschiene 11 ruht in eingebautem Zustand auf einem schmalen Betonfundament 16.The supporting structure 1 carries the essentially horizontally running, annular outer supporting frame 4, which is connected to support feet 9 pointing downward. The support feet 9 are fastened with their lower ends 10 on foot rails 11. The foot rails 11 extend in central directions via receptacles of the support feet 9 in the direction of a central axis of the supporting structure 1 or of the inner free space 2, and each carry at their inner ends 12 a holding device 13 for a support rod 14 for supporting the inner support frame 15. In the installed state, each foot rail 11 rests on a narrow concrete foundation 16.

In den ringförmigen äußeren Tragrostrahmen 4 werden Tragroste 17 eingesetzt, die wiederum mit einem feinmaschigen Gitterwerk 18 abgedeckt werden.In the annular outer support frames 4, support gratings 17 are used, which in turn are covered with a fine-mesh latticework 18.

Das Tragwerk 1 umschließt somit einen zu schützenden Wurzelraum 19 und bildet an seiner Oberseite 20 die große Öffnung 3 aus, durch die der Baum 7 mit seinen Wurzelballen 8 gepfanzt und auch wieder verpflanzt werden kann.The supporting structure 1 thus encloses a root space 19 to be protected and forms on its upper side 20 the large opening 3 through which the tree 7 with its root balls 8 can be planted and also transplanted again.

Um den Wurzelraum 19 auch im Bereich der Öffnung 3 nach oben hin gegen Auflastdruck und Verdichtung zu schützen, wird nach der Pflanzarbeit von oben der innere Tragrostrahmen 15 eingesetzt, in den wiederum Tragroste 21 eingefügt sind, die wiederum mit den feinmaschigen Gitterwerk 18 abgedeckt werden.In order to protect the root space 19 in the area of the opening 3 upwards against load pressure and compression, the inner support frame 15 is inserted after the planting work, into which support grids 21 are inserted, which in turn are covered with the fine-mesh lattice work 18.

Der innere Tragrostrahmen 15 besteht aus zwei oder mehreren miteinander verbundenen bzw. verschraubten Segmenten 22, die für den Baumstamm 23 eine Öffnung 24 bilden, die groß genug für das ungestörte Dickenwachstum des Baumstammes 23 ist.The inner support frame 15 consists of two or more segments 22 which are connected or screwed together and which form an opening 24 for the tree trunk 23 which is large enough for the undisturbed growth of the tree trunk 23.

Der innere Tragrostrahmen 15 wird nach innen mit den Abstützungsstäben 14 gegen Auflast abgestützt. Das Einfügen der Abstützungsstäbe 14 erfolgt erst, wenn die Pflanzarbeit beendet ist, d.h. wenn der gesamte Wurzelraum 19 bis zur Oberkannte der Tragrostrahmen 4 und 15 mit Pflanzerde 6 verfüllt ist.The inner support frame 15 is supported on the inside with the support rods 14 against load. The support rods 14 are not inserted until the planting work has ended, i.e. when the entire root area 19 up to the upper edge of the support frames 4 and 15 is filled with planting soil 6.

Die Segemente des inneren Tragrostrahmens 15 weisen Führungsmanschetten 25 für die Abstützungsstäbe 14 auf, wobei die Führungsmanschetten 25 der Mittelachse des Tragwerkes 1 parallellaufen und an Streben 31 der Segmente 22 angeordnet sind, die auf die Mittelachse ausgerichtet sind. Das Einfügen der Abstützungsstäbe 14 erfolgt in der Weise, daß jeder Abstützungsstab 14 durch die Führungsmanschette 25 richtungsgenau so durch die Pflanzerde 6, ggf. bei Großbaumverpflanzung durch den Rand des Wurzelballens 8 gepreßt wird, daß das untere Ende 26 des Abstützungsstabes 14 paßgenau auf die Aufnahmevorrichtung 13 am inneren Ende 12 der Fußschiene 11 trifft. Der Abstützungsstab 14 wird an seinem oberen Ende 27 mit dem inneren Tragrostrahmen 15 im Bereich der Führungsmanschette 25 verschraubt.The segments of the inner supporting frame 15 have guide sleeves 25 for the support rods 14, the guide sleeves 25 running parallel to the central axis of the supporting structure 1 and being arranged on struts 31 of the segments 22 which are aligned with the central axis. The insertion of the support rods 14 is carried out in such a way that each support rod 14 is pressed by the guide sleeve 25 in the correct direction through the potting soil 6, possibly in the case of large tree transplantation through the edge of the root ball 8, that the lower end 26 of the support rod 14 fits snugly on the receiving device 13 meets at the inner end 12 of the foot rail 11. The support rod 14 is screwed at its upper end 27 to the inner support frame 15 in the region of the guide sleeve 25.

Damit das untere Ende 26 des Abstützungsstabes 14 trotz Einbautoleranzen und unkontrollierbaren Seitendrücken durch unterschiedliche Bodendichten oder Wurzeln genau im statisch vorbestimmten Punkt der Aufnahmevorrichtung 13 eintrifft und damit dann die statisch notwendige Krafteinleitung herstellen kann, ist die Aufnahmevorrichtung 13 in der Weise ausgeformt, daß ein trichterförmiger Aufnahmeteller den an seinem unteren Ende 26 analog abgeschrägten Abstützungsstab 14 aufnimmt, auch wenn dieser beim Einpressen etwas schräg ankommt. Dann wird er durch die Trichterform auf den statisch vorbestimmten Punkt zentriert.So that the lower end 26 of the support rod 14, despite installation tolerances and uncontrollable side pressures due to different soil densities or roots, arrives exactly at the statically predetermined point of the receiving device 13 and can then produce the statically necessary introduction of force, the receiving device 13 is shaped in such a way that a funnel-shaped receiving plate which receives at its lower end 26 angled support rod 14, even if it arrives somewhat obliquely when pressed in. Then it is centered on the statically predetermined point by the funnel shape.

Der Vorrichtung kann ferner mit einer Bewässerungseinrichtung 28 und einem Baumschutzgitter 29 versehen werden, das den Baumstamm 23 vor Beschädigungen schützt.The device can also be provided with an irrigation device 28 and a tree guard 29 which protects the tree trunk 23 from damage.

Auf die Vorrichtung kann dann das in den Einsatzbereichen häufig verwendete Kleinpflaster 30 aufgelegt werden.The small plaster 30 frequently used in the fields of application can then be placed on the device.
