Description

Die Erfindung bezieht sich auf einen mit Rasen bepflanzbaren Pflasterstein zum Aufnehmen von Verkehrslasten, bestehend aus einem Formkörper mit einer wenigstens eine Füllöffnung für Erde umschließenden, bodenlosen Wandung, die um den Umfang verteilte Abschnitte mit abstehenden, die Wandungsabschnitte begrenzenden Wandstegen zum Anschluß gleichartiger Pflastersteine bildet, wobei in den Wandungsabschnitten und den Wandstegen gegen den Boden offene Durchtrittsöffnungen vorgesehen sind, die im Bereich der Wandstege gegen deren Anschlußflächen hin offen sind.The invention relates to a paving stone that can be planted with lawn for taking up traffic loads, consisting of a molded body with a bottomless one that encloses at least one filling opening for soil Wall, the sections distributed around the circumference with protruding, the wall sections delimiting wall bars for connecting similar paving stones forms, being in the wall sections and the wall webs through openings open to the floor are provided in the area the wall webs are open towards their connecting surfaces.

Es ist bekannt (EP 0 668 399 A2), bepflanzbare Pflastersteine auf einem befestigten, allfällige Verkehrslasten abtragenden Untergrund zu verlegen, bevor in die Füllöffnungen Erde eingebracht wird, die dann beispielsweise mit einem Rasen bepflanzt werden kann. Aufgrund der der Höhe nicht bepflanzbarer Pflastersteine angepaßten Wandungshöhe der bepflanzbaren Pflastersteine ergibt sich allerdings ein vergleichsweise dünnes Erdbett für die Bepflanzung, die dadurch beeinträchtigt wird. Das Verlegen der bepflanzbaren Pflastersteine auf einem vorbereiteten Erdbett, das sich mit der in die Füllöffnungen der Pflastersteine eingefüllten Erde verbinden kann, verbietet sich jedoch im allgemeinen, weil ein für das Durchwachsen ausreichend aufgelockertes Erdreich keine hinlängliche Druckfestigkeit zur Aufnahme von Verkehrslasten mit sich bringt. Dazu kommt, daß das in die Füllöffnung der Pflastersteine eingefüllte Erdreich wegen der geringen, auf die Steinhöhe beschränkten Fließstrecken kaum eine Filterwirkung auf umweltbelastende Leckflüssigkeiten, wie Öle oder Benzin, ausüben kann, womit bei Verkehrsflächen gerechnet werden muß, so daß die Gefahr besteht, daß diese Leckflüssigkeiten im wesentlichen ungefiltert bis zum Grundwasser durchsickern können.It is known (EP 0 668 399 A2) that paving stones can be planted on a before laying any paved subsurface that can carry off traffic loads earth is introduced into the filling openings, which is then, for example, with a Lawn can be planted. Because of the height of the paving stones that cannot be planted adjusted wall height of the plantable paving stones However, there is a comparatively thin bed of soil for planting, which results from this is affected. Laying the plantable paving stones on a prepared bed of earth that fits into the fill openings of the paving stones connected earth, but generally prohibits because a soil that is sufficiently loosened for growing through is not sufficient Compressive strength for absorbing traffic loads. To comes that the filled in the filling opening of the paving stones because of the small flow distances, limited to the stone height, hardly any filter effect exercise on polluting liquids such as oils or petrol can, what must be expected in traffic areas, so that the danger is that these drainage liquids are essentially unfiltered down to the groundwater can leak.

Zur Befestigung von mechanisch hoch beanspruchten Sportplatzrasenflächen ist es bekannt (DE 31 40 701 A1), Gitterkörper aus einander kreuzenden Stegteilen zu versetzen, die zwischen sich Kammern zur Aufnahme von mit Rasen bepflanzbarem Erdreich bilden. Die Durchwachsbarkeit dieses Gitterkörpers wird durch Durchtrittsöffnungen zwischen den einzelnen Kammern unterstützt. Solche bekannte Rasenbewehrungen eignen sich jedoch nicht zum Aufnehmen von Verkehrslasten, zumal sie aus einem flexiblen, gummiartigen Material bestehen.For fastening mechanically highly stressed sports field lawns it is known (DE 31 40 701 A1), lattice bodies crossing from one another To move web parts, the chambers between them for receiving with Form lawn that can be planted with. The tractability of this lattice body is supported by openings between the individual chambers. However, such known lawn reinforcements are not suitable for picking up of traffic loads, especially since they are made of a flexible, rubber-like material consist.

Schließlich ist es bekannt (DE 86 00 430 U), zur Befestigung befahrbarer Flächen Gitterplatten aus einander kreuzenden Gitterwänden einzusetzen, bei denen für einen sich möglichst über die Gitterwände hinweg erstreckenden Rasenbewuchs dadurch gesorgt werden soll, daß in den je eine Kammer bildenden Wandungsabschnitten zwischen den Kreuzungsstellen und den über diese Wandungsabschnitte vorstehenden Stegen sowohl an der Ober- als auch an der Unterseite halbkreisförmige Ausnehmungen vorgesehen werden. Während die oberen Ausnehmungen für das Zusammenwachsen der Rasenabschnitte über die Gitterwände sorgen sollen, dienen die unteren Ausnehmungen sowohl zur Gewichtsreduzierung als auch zur verbesserten Drainage der einzelnen Kammern. Eine Filterwirkung für umweltschädliche Leckagen ist jedoch bei solchen Gitterplatten nicht möglich.Finally, it is known (DE 86 00 430 U) that can be driven over for fastening To use surfaces of grid plates made of crossing grid walls at those for a lawn covering that extends as far as possible across the grid walls should be ensured that in each forming a chamber Wall sections between the crossing points and those over these wall sections protruding webs on both the top and the Bottom semi-circular recesses are provided. While the upper recesses for the growing together of the lawn sections over the lattice walls are intended to serve, the lower recesses serve both Weight reduction as well as improved drainage of the individual chambers. However, there is a filter effect for environmentally harmful leaks Grid plates not possible.

Der Erfindung liegt somit die Aufgabe zugrunde, einen mit Rasen bepflanzbaren Pflasterstein der eingangs geschilderten Art so zu verbessern, daß nicht nur vorteilhafte Bepflanzungsbedingungen geschaffen, sondern auch gute Voraussetzungen zum Ausnützen der Filterwirkung des in die Pflastersteine gefüllten Erdreiches auf umweltbelastende Leckflüssigkeiten sichergestellt werden können. The invention is therefore based on the object of being plantable with lawn To improve paving stone of the type described above so that not only created advantageous planting conditions, but also good ones Requirements to take advantage of the filter effect of the in the paving stones filled soil to ensure that polluting liquids are not harmful to the environment can.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Durchtrittsöffnungen durch sich über ein Drittel der Wandungshöhe erstreckende Schlitze gebildet sind und unterhalb des Hauptwurzelungsbereiches des bepflanzbaren Rasens enden.The invention solves the problem in that the passage openings through slots extending over a third of the wall height are formed and below the main root area of the plantable Lawn ends.

Durch diese Maßnahmen wird zunächst eine ausreichende Erdfüllung unterhalb des Wurzelungsbereiches eines gepflanzten Rasens für eine gute Filterwirkung sichergestellt, weil vor allem in diesem unterhalb des Wurzelungsbereiches befindlichen Erdreich die angestrebte Filterwirkung auftritt. Die dadurch bedingte Höhe des Pflastersteins ist jedoch nicht hinreichend, weil die einzelnen Füllöffnungen vertikale Strömungskanäle bilden, die einer Verteilung der zu filternden Flüssigkeit über eine möglichst große Fläche entgegenstehen. Deshalb sind in den Wandungsabschnitten und Wandstegen vom Boden aufragende Schlitze vorgesehen, die unterhalb des Wurzelungsbereiches enden und sich über ein Drittel der Wandungshöhe erstrecken, was einerseits für die Festigkeitsanforderungen und anderseits für die Filterwirkung vorteilhafte Verhältnisse schafft. Diese Schlitze müssen sich auch im Bereich der Anschlußflächen der Wandstege ergeben, damit nicht die aneinanderliegenden Anschlußflächen zweier benachbarter Pflastersteine einen über die Wandungshöhe durchgehenden Spalt für das ungefilterte Versickern von zu filtrierender Flüssigkeit bilden können.Through these measures, there is initially sufficient soil filling below the root area of a planted lawn for a good one Filter effect ensured, especially in this below the root area the desired filter effect occurs. The result conditional height of the paving stone is not sufficient, however, because the individual Filling openings form vertical flow channels that allow for a distribution of the oppose filtering liquid over as large an area as possible. Therefore are protruding from the floor in the wall sections and wall bridges Slits are provided that end below the root area and themselves extend over a third of the wall height, which on the one hand for strength requirements and on the other hand conditions advantageous for the filter effect creates. These slots must also be in the area of the pads Wall bars result, so that not the adjoining connection surfaces two adjacent paving stones one continuous over the wall height Form a gap for the unfiltered infiltration of liquid to be filtered can.

Die Anzahl und Anordnung der von der Wandung für den Füllraum abstehenden Wandstege kann an sich in Abhängigkeit von der Querschnittsform des Füllraumes bzw. der ihn umschließenden Wandung den jeweiligen Anforderungen entsprechend gewählt werden. Insbesondere bei rechtwinkeligen Wandungen der Formkörper für die Pflastersteine ergeben sich jedoch vorteilhafte Konstruktionsverhältnisse, wenn die Wandungsabschnitte über die Eckbereiche der Wandung verlängert sind und mit ihren Verlängerungen die die jeweils benachbarten Wandabschnitte begrenzenden Wandstege bilden. Bei einer solchen Ausführungsform können von den abstehenden Wandstegen dem Querschnitt der Füllräume entsprechende Zwischenräume zwischen den Pflastersteinen begrenzt werden, so daß sich eine über die gesamte Pflasterfläche gleichmäßige Erdverteilung ergibt. Für den Fall, daß die abstehenden Wandstege zumindest zweier Wandungsabschnitte rotationssymmetrisch angeordnet sind, verlaufen die Teilungsebenen zwischen den Pflastersteinen zu diesen symmetrisch, wobei sehr einfache Versetzungsverhältnisse geschaffen werden.The number and arrangement of those protruding from the wall for the filling space Wall bars can in themselves depend on the cross-sectional shape the filling space or the wall surrounding it the respective requirements be chosen accordingly. Especially with right-angled walls however, the shaped bodies for the paving stones are advantageous Construction relationships if the wall sections over the corner areas the wall are extended and with their extensions the neighboring ones Form wall sections delimiting wall sections. With one Embodiment can cross-section of the protruding wall webs corresponding spaces between the paving stones of the filling spaces be limited so that there is a uniform over the entire paved area Earth distribution results. In the event that the protruding wall webs at least two wall sections are arranged rotationally symmetrical, the run Partition planes between the paving stones symmetrical to these, whereby very simple transfer relationships can be created.

Der Pflasterstein gemäß dem dargestellten Ausführungsbeispiel besteht aus einem aus Beton gegossenen Formkörper mit einer im Grundriß quadratischen Wandung 1, die eine im Querschnitt ebenfalls quadratische Füllöffnung 2 umschließt. Die die Füllöffnung 2 umschließenden Wandungsabschnitte sind mit 3 bezeichnet. Im unteren Drittel der Wandungsabschnitte 3 sind Durchtrittsöffnungen 4 vorgesehen, die in Form von vom Wandungsboden ausgehenden Schlitzen ausgebildet sind. Diese Durchtrittsöffnungen 4 erstrecken sich unterhalb des Hauptwurzelungsbereiches üblicher Rasenpflanzen, so daß die Wandungshöhe erheblich größer als bei herkömmlichen Pflastersteinen ausfällt Damit ergeben sich bezüglich der Dicke des Erdbettes vorteilhafte Bedingungen für eine Bepflanzung, ohne die Nachteile in Kauf nehmen zu müssen, die sich sonst zufolge des begrenzten Aufnahmevolumens der Füllöffnungen 2 einstellen.The paving stone according to the illustrated embodiment is from a molded body made of concrete with a square plan Wall 1, which has a filling opening 2 that is also square in cross section encloses. The wall sections surrounding the filling opening 2 are included 3 designated. In the lower third of the wall sections 3 are through openings 4 provided, in the form of outgoing from the wall floor Slots are formed. These through openings 4 extend below the main rooting area of common lawn plants, so that the wall height is considerably larger than with conventional paving stones This results in advantageous conditions with regard to the thickness of the earth bed for a planting without having to accept the disadvantages that arise otherwise set due to the limited receiving volume of the filling openings 2.

Die Wandung 1 ist jeweils über den Eckbereich hinaus zu Wandstegen 5 verlängert, deren von der Wandung 1 abgekehrte Stirnseiten Anschlußflächen 6 für benachbarte gleichartige Pflastersteine bilden. Die Wandstege 5 weisen entsprechend den Wandungsabschnitten 3 Durchtrittsöffnungen 7 auf, die jedoch zu den Anschlußflächen 6 hin offen und nur halb so breit wie die Durchtrittsöffnungen 4 in den Wandungsabschnitten 3 sind. Da außerdem die Breite b der Wandstege 5 der halben Länge I der Wandungsabschnitte 3 entspricht, ergibt sich zwischen aneinandergesetzten gleichartigen Pflastersteinen ein Zwischenraum 8, der der Füllöffnung 2 innerhalb der Wandung 1 entspricht und mit dieser über die Durchtrittsöffnung 4 in Verbindung steht, wie auch die Zwischenräume 8 untereinander über die Durchtrittsöffnungen 7 verbunden sind, die sich im Bereich der aneinanderstoßenden Wandstege 4 zu einer gemeinsamen, den Durchtrittsöffnungen in den Wandungsabschnitten 3 entsprechenden Öffnung ergänzen. Aus den Fig. 2 und 3 ist dieser Zusammenhang ohne weiteres ersichtlich. Es ergibt sich somit auch zwischen den einzelnen Pflastersteinen eine Erdbefüllung, die eine Filterwirkung für auf die Bepflasterung ausfließende Leckflüssigkeit mit sich bringt. Über die Durchtrittsöffnungen 4 und 7 wird eine erdbefüllte Verbindung zwischen den Füllöffnungen 2 benachbarter Pflastersteine über die ebenfalls erdbefüllten Zwischenräume 8 geschaffen, was einen Feuchtigkeitsund Nährstoffausgleich über die gesamte bepflasterte Fläche ermöglicht. Außerdem werden nicht nur größere vertikale, sondern vor allem auch große, zur bepflasterten Fläche parallele Fließstrecken erreicht, die eine gute Filterwirkung für Leckflüssigkeiten mit sich bringen.The wall 1 is in each case beyond the corner area to wall webs 5 extended, the end faces facing away from the wall 1, connecting surfaces 6 form for adjacent similar paving stones. The wall webs 5 have corresponding to the wall sections 3 through openings 7, however open towards the connecting surfaces 6 and only half as wide as the passage openings 4 are in the wall sections 3. Since also the width b of Wall webs 5 corresponds to half the length I of the wall sections 3 there is a space between similar paving stones 8, which corresponds to the filling opening 2 within the wall 1 and with this is connected via the passage opening 4, as are the interspaces 8 are connected to each other via the passage openings 7, which are in the area the abutting wall webs 4 to a common, the Through openings in the wall sections 3 corresponding opening complete. This relationship is readily apparent from FIGS. 2 and 3. So there is also an earth filling between the individual paving stones, which has a filter effect for leakage liquid flowing onto the paving brings with it. An earth-filled is through the openings 4 and 7 Connection between the filling openings 2 of adjacent paving stones via the also earth-filled spaces 8 created, which a moisture and Nutrient balance over the entire paved area enables. Moreover not only become larger vertical ones, but especially large ones, too Surface parallel flow sections reached, which has a good filter effect for Bring leak fluids with them.

Die Erfindung ist selbstverständlich nicht auf das dargestellte Ausführungsbeispiel beschränkt, weil es vor allem auf die unterhalb des Hauptwurzelungsbereiches von Rasenpflanzen vorgesehenen Durchtrittsöffnungen 4 in den Wandungsabschnitten 3 und den Durchtrittsöffnungen 7 in den Wandstegen 5 ankommt. So kann die Grundrißform der Füllöffnung 2 von der Grundrißform der Wandung 1 abweichen. Es können auch Pflastersteine zum Einsatz kommen, die zwei oder mehrere Füllöffnungen aufweisen, wenn sichergestellt ist, daß die Füllöffnungen eines Pflastersteines über entsprechende Durchtrittsöffnungen 4 bzw. 7 miteinander in Verbindung stehen.The invention is of course not based on the illustrated embodiment limited because it is mainly to those below the main root area provided by lawn plants through openings 4 in the Wall sections 3 and the passage openings 7 in the wall webs 5 arrives. So the outline of the filling opening 2 from the outline of the Wall 1 deviate. Paving stones can also be used have two or more filling openings if it is ensured that the Filling openings of a paving stone via corresponding passage openings 4 or 7 are connected.
