Abstract

The root-space protection comprises a basic component (1) forming the root space and a cover (9) with a trunk aperture. In order to suit the root-space protection to the biological, technical and aesthetic requirements, the proposal is for a structural insert in which the basic component (1) is subdivided transversely to its vertical axis (2) into at least two parts (3, 4), where the upper part has a recess (5) for the cover.

Description

Bauteilsatz zur Herstellung eines WurzelraumschutzesComponent set for the production of root protection
Die vorliegende Erfindung bezieht sich auf einen Bauteilsatz zur Herstellung eines Wurzelraumschutzes gemäss dem Ober- begriff des Anspruchs 1.The present invention relates to a set of components for producing a root canal protection according to the preamble of claim 1.
Ein Wurzelraumschutz (auch Baumkranz genannt) weist einen in der Erde versenkbaren Fundamentrahmen (auch Basiselement genannt) auf, in den ein Baum mit seiner Wurzel eingepflanzt wird und der die Wurzel schützend umgibt. Im Bereich der den Baum umgebenden Verkehrsfläche ist das Basiselement mit einer Fassung versehen, in die nach dem Pflanzen des Baumes eine mindestens zweiteilige Abdeckung einlegbar ist, die eine den Baumstamm umgebende Öffnung aufweist. Die Abdeckung besteht aus Elementen, die nach Art eines Zusammensetzspiels zusammenfügbar sind. Bei der Abdeckung des in den DE-OS 'n 40 09 612 und 40 09 613 gezeigten Wurzelraumschutzes können die Elemente beim Einlegen in die Fassung unterschiedlich zu¬ sammengefügt oder gegenseitig verdreht und damit die Exzen- trizität der Stammδffnung gewählt werden. Dieser Wurzelraum¬ schutz hat indessen den Nachteil, dass das Basiselement hinsichtlich Grosse, insbesondere hinsichtlich seiner Tiefe fest vorgegebenen ist. Auch die Wurzeldurchtrittsöffnungen in der Wand des Basiselementes sind fest vorgegeben. Dabei ist der damit schützbare Wurzelraum der Wurzelform desA root protection (also called tree wreath) has a foundation frame (also called base element) that can be sunk into the ground, into which a tree is planted with its root and which protects the root. In the area of the traffic area surrounding the tree, the base element is provided with a holder into which, after planting the tree, an at least two-part cover can be inserted, which has an opening surrounding the tree trunk. The cover consists of elements that can be put together in the manner of an assembly game. When covering the root space protection shown in DE-OS 'n 40 09 612 and 40 09 613, the elements can be put together differently when inserted into the socket or rotated relative to one another and thus the eccentricity of the trunk opening can be selected. However, this protection of the root area has the disadvantage that the base element is fixed in terms of size, in particular its depth. The root openings in the wall of the base element are also predefined. The root space that can be protected is the root shape of the
Baumes nicht anpassbar, was dessen Wachstum beeinträchtigt. Ebenso kann die Tiefe des seitlichen Wurzelaustritts aus dem Basiselement nicht den Anforderungen des Strassenbauingen- ieurs angepasst werden, so dass die Gefahr besteht, dass einzelne der Baumwurzeln in zu geringer Tiefe austreten und den Strassenbelag anheben.Tree is not adaptable, which impairs its growth. Likewise, the depth of the lateral root exit from the base element cannot be adapted to the requirements of the road construction engineer, so that there is a risk that some of the tree roots will emerge too little and raise the road surface.
Zur Beseitigung dieser Nachteile ist ein Wurzelraumschutz bekannt geworden, bei dem das Basiselement aus im Quer- schnitt rechteckigen Betonbalken aufgebaut ist. Beim Aufbau werden auf den ebenen Boden einer Grube blockhausartig parallele Balkenpaare um jeweils 90° gedreht aufeinander gelegt, bis das Basiselement die gewünschte Höhe hat. Die offenen Stellen in den vier Wänden des Basiselementes werden dort wo kein Wurzelaustritt erfolgen darf mit etwas kleine¬ ren Balken gleichen Querschnitts verschlossen. Dieses Basis¬ element hat den Nachteil geringer Eigenstabilität und könnte auf Dauer die darauf wirkende Verkehrsbealstung nicht zu¬ reichend aufnehmen. Die Abdeckung wird daher auf einem das Basiselement umgebenden Pfahlfundament abgestützt, wozu auf die Pfähle ein Rahmen mit einer die Abdeckung aufnehmenden Fassung befestigt wird. Weiter ist es bei diesem Wurzelraum- schütz nicht möglich, das Basiselement zur Bildung eines Randsteins über die Verkehrsfläche hinaus vorstehen zu lassen.To eliminate these disadvantages, root protection has become known in which the base element is constructed from concrete beams which are rectangular in cross section. During construction, parallel pairs of beams are placed on top of each other on the flat floor of a pit, rotated by 90 °, until the base element has the desired height. The Open places in the four walls of the base element are closed with somewhat smaller beams of the same cross-section where no root emergence may occur. This basic element has the disadvantage of low intrinsic stability and in the long run could not adequately absorb the traffic congestion acting on it. The cover is therefore supported on a pile foundation surrounding the base element, for which purpose a frame with a holder receiving the cover is fastened to the posts. Furthermore, it is not possible with this root space protection to let the base element protrude beyond the traffic area to form a curb.
Bei allen bekannten Einrichtungen zum Schütze des Wurzel- raumes ist der nach dem Einbau sichtbare Teil nur beschränkt dem Stil der umgebenden Verkehrsfläche anpassbar.In all known devices for protecting the root area, the part visible after installation can only be adapted to a limited extent to the style of the surrounding traffic area.
Die vorliegende Erfindung stellt sich daher die Aufgabe, Mittel zu schaffen, mit denen ein Wurzelraumschutz ohne die genannten Nachteile herstellbar ist und bei dem in einfacher Weise die Neigung des Abdeckung der Neigung der angrenzenden Verkehrsfläche anpassbar ist.The present invention therefore has as its object to provide means with which root canal protection can be produced without the disadvantages mentioned and in which the inclination of the inclination of the inclination of the adjacent traffic area can be adjusted in a simple manner.
Erfindungsgemäss wird diese Aufgabe gelöst durch die kenn- zeichnenden Merkmale des Anspruchs 1.According to the invention, this object is achieved by the characterizing features of claim 1.
Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
Fig. 1 ein aus mehreren Bauteilen zusammengesetztes Basis¬ element, Fig. 2 und 3 verschiedene mit den Bauteilsatz herstellbare1 shows a basic element composed of several components, FIGS. 2 and 3 different ones that can be produced with the component set
Ausführungsformen des Basiselementes, wobei der oberste, die Fassung aufweisende Teil wegge- lassen ist,Embodiments of the base element, the uppermost part having the socket being omitted,
Fig. 4 das Basiselement nach Fig. 1 mit verschiedenen die Fassung aufweisenden Teilen, Fig. 5 weitere Ausführungsformen des die Fassung aufweisen¬ den Teils des Basiselementes mit in die Fassung eingelegter Abdeckung und Fig. 6 weitere Ausführungsformen der Abdeckung.4 shows the base element according to FIG. 1 with various parts having the holder, 5 further embodiments of the part of the base element comprising the holder with the cover inserted into the holder, and FIG. 6 further embodiments of the cover.
Das in Fig. 1 gezeigte Basiselement 1 ist quer zu seiner Vertikalachse 2 in drei Teile 3, 4 geteilt. Die beiden unteren Teile sind gleich, wogegen das oberste Teil 3 in der Form abweicht und mit einer Fassung 5 versehen ist, in die eine Abdeckung (Fig. 6) einlegbar ist. Vier Gewindeschäfte 6 verbinden das oberste Teil 3 mit dem nach unten anschlies- senden Teil 4. Der Abstand zwischen diesen beiden Teilen 3, 4 ist durch nicht sichtbare, auf die Gewindeschäfte 6 auf¬ geschraubte Muttern einstellbar. Durch ein Verstellen dieser Muttern kann die Neigung des obersten Teils 3 mit Bezug auf die Vertikalachse verändert und der Neigung der angrenzenden Verkehrsfläche angepasst werden. Abstandhalter 7 halten die unteren Teile 4 distanziert und bilden Durchtrittsöffnungen 8, durch welche die Wurzeln eines eingepflanzten Baumes in das umgebende Erdreich hindurchwachsen können. Wie Fig. 2 zeigt, können je nach der für das Basiselement 1 gewünschten Tiefe an das oberste Teil 3 nach unten eines oder mehrere der rahmenförmigen Teile 4 anschliessen. Ist über die ganze Tiefe des Wurzelraumschutzes kein seitlicher Wurzelaustritt erwünscht, werden die Teile 4 unmittelbar aufeinander gelegt (Fig. 2b bis 2d) ; andernfalls werden Abstanhalter 7 zwischen die Teile 4 gelegt (Fig. 3). Darf aber nur bis zu einer bestimmten Tiefe unter der Verkehrsfläche kein seitlicher Wurzelaustritt erfolgen (um beispielsweise ein Aufbuckeln der Verkehrsfläche durch die Baumwurzel zu vermeiden), werden die Teile 4 bis in diese Tiefe unmittelbar aufein¬ ander gelegt und erst in grösserer Tiefe mittels der Abstandhalter 7 distanziert.The base element 1 shown in FIG. 1 is divided into three parts 3, 4 transversely to its vertical axis 2. The two lower parts are the same, whereas the uppermost part 3 differs in shape and is provided with a holder 5, into which a cover (FIG. 6) can be inserted. Four threaded shafts 6 connect the uppermost part 3 to the part 4 adjoining at the bottom. The distance between these two parts 3, 4 can be adjusted by nuts (not visible) screwed onto the threaded shafts 6. By adjusting these nuts, the inclination of the uppermost part 3 with respect to the vertical axis can be changed and adapted to the inclination of the adjacent traffic area. Spacers 7 keep the lower parts 4 at a distance and form passage openings 8 through which the roots of a planted tree can grow into the surrounding soil. As shown in FIG. 2, depending on the depth desired for the base element 1, one or more of the frame-shaped parts 4 can be connected to the uppermost part 3 at the bottom. If no lateral root emergence is desired over the entire depth of the root protection, the parts 4 are placed directly on top of one another (FIGS. 2b to 2d); otherwise, standoffs 7 are placed between the parts 4 (FIG. 3). If, however, the roots do not emerge laterally to a certain depth below the traffic area (for example to prevent the traffic area from hunching up due to the tree root), the parts 4 are placed one on top of the other immediately and only at a greater depth using the spacers 7 distanced.
Fig. 4d zeigt das gleiche Basiselement wie Fig. 1. Um dessen Erscheinungsbild stilistisch der Umgebung des Baumes an¬ passen zu können ist das oberste Teil 3 in verschiedenen Ausführungsformen vorhanden. Die Fig. 4a bis 4c zeigen eine acht-, eine sechs- bzw. viereckige Rahmenform für die Ab¬ deckung. Bei allen obersten Teilen 3 sind unabhängig von ihrer Form die Abstände 9 ' der Führungen 9 für die Gewinde- schäfte 6 sowie die Form der Fassungen 5 gleich. Somit können auf die Teile 3 mittels der Gewindeschäfte 6 wahl¬ weise einer der in Fig. 4 gezeigten Teile angebracht werden.FIG. 4d shows the same basic element as FIG. 1. In order to be able to adapt its appearance stylistically to the surroundings of the tree, the uppermost part 3 is available in various embodiments. 4a to 4c show one octagonal, hexagonal or quadrangular frame shape for the covering. For all uppermost parts 3, regardless of their shape, the distances 9 'of the guides 9 for the threaded shafts 6 and the shape of the sockets 5 are the same. Thus, one of the parts shown in FIG. 4 can be attached to the parts 3 by means of the threaded shafts 6.
Die Teile 3 können anstatt in Beton auch in Gusseisen oder in einem anderen Material hergestellt sein und durch die Materialwahl der Umgebung des Baumes angepasst werden. Das gleiche gilt für die Abdeckung 10, die in den Fig. 5a und 5c aus Gusseisen besteht und in Fig. 5b mit einem Pflaster¬ steinbelag verblendet ist.The parts 3 can be made of cast iron or another material instead of concrete and can be adapted to the environment of the tree by the choice of material. The same applies to the cover 10, which consists of cast iron in FIGS. 5a and 5c and is covered with a paving stone covering in FIG. 5b.
Die Fig. 6a bzw. 6b zeigen Abdeckungen aus Gusseisen bzw.6a and 6b show covers made of cast iron or
Beton. Nebst den Abdeckungen 10 sind noch Eckverzierungen 11 gezeigt, die in Verbindung mit dem Teil 3 gemäss Fig. 4c verwendbar sind. Diese Eckverzierungen 11 werden bei jenem Teil (Fig. 4c) in stilistischer Übereinstimmung mit der in der Fassung 5 eingeigten Abdeckung 10 ausgewählt und in ent¬ sprechende Ausnehmungen 12 eingelegt, in denen sie mit der Oberfläche des Basiselementes bündig sind.Concrete. In addition to the covers 10, corner ornaments 11 are also shown, which can be used in connection with part 3 according to FIG. 4c. These corner decorations 11 are selected in that part (FIG. 4c) in a stylistic manner in accordance with the cover 10 which has been integrated in the holder 5 and are inserted in corresponding recesses 12 in which they are flush with the surface of the base element.
Die rahmenförmigen Teile 3 und 4 können aus zwei oder vier zur Vertikalachse 2 radial symmetrischen Segmenten zusammen¬ gesetzt sein. Ebenso die Abdeckung 10, wobei diese aus min¬ destens zwei Segmenten bestehen muss.The frame-shaped parts 3 and 4 can be composed of two or four segments which are radially symmetrical with respect to the vertical axis 2. Likewise, the cover 10, which must consist of at least two segments.
Trotz der vergleichsweise geringen Zahl verschiedener Bau- teile können mit dem beschriebenen Bauteilsatz eine Vielzahl unterschiedlicher Baumkränze hinsichtlich Tiefe, Lage der Wurzelaustrittsöffnungen, des Erscheinungsbildes und der Neigung der Verkehrsfläche angefertigt werden. Der Bauteil¬ satz hat zudem den Vorteil, dass sein Erscheinungsbild Mode bedingten Änderungen des Geschmackes mit wenig Aufwand an¬ passbar ist, indem lediglich die Teile 3 und die Abdeckung 10 einer neuen Modeform angepasst werden müssen. Despite the comparatively small number of different components, the described component set can be used to manufacture a large number of different tree wreaths with regard to depth, position of the root outlet openings, the appearance and the inclination of the traffic area. The component set also has the advantage that its appearance can be adapted to changes in taste due to fashion with little effort, since only parts 3 and cover 10 have to be adapted to a new fashion form.
