Description

Die Erfindung betrifft ein Pflasterelement aus Kunststoff zur Befestigung von Bodenflächen, das in einer bevorzugten Ausgestaltung eine durchgehende obere Wandfläche hat.The invention relates to a plaster element made of plastic for fastening Floor surfaces, which in a preferred embodiment is a continuous upper Has wall surface.

Das Pflasterelement dient typischerweise zur Befestigung von Bodenflächen, die aus Erde, Sand, Kies oder dergleichen bestehen und die dauerhaft oder vorübergehend befahren oder begangen werden sollen. Das Pflasterelement kann aber auch zur Markierung von Bodenflächen, beispielsweise zur Kenntlichmachung von Parkplätzen eingesetzt werden.The paving element is typically used to attach floor surfaces consist of earth, sand, gravel or the like and which are permanent or to be driven on or committed temporarily. The patch element can but also for marking floor areas, for example for identification purposes from parking lots.

Das Pflasterelement besteht aus Kunststoff, wobei bevorzugt, jedoch nicht ausschließlich Recyclingmaterial verwendet werden kann.The plaster element is made of plastic, preferably, but not only recycling material can be used.

Anstelle der früher üblichen Pflastersteine sind bereits Pflasterelemente bekannt geworden, die aus Kunststoff bestehen und - aus Gründen der Festigkeit - einen Vollquerschnitt haben. Diese Pflasterelemente benötigen demnach große Mengen Kunststoffmaterial zu ihrer Herstellung, was sich in verhältnismäßig hohen Herstellungskosten niederschlägt. Außerdem werden diese vorbekannten Pflasterkunststoffelemente wie die herkömmlichen Pflastersteine in einem Mörtelbett aneinandergereiht, damit eine (weitgehend) ebene Fahr- oder Trittfläche entsteht, was mit einem beträchtlichen Bearbeitungsaufwand verbunden ist.Instead of the previously used paving stones, paving elements are already known that are made of plastic and - for reasons of strength - one Have full cross-section. These pavement elements therefore require large quantities Plastic material for their manufacture, which can be found in relatively high Manufacturing costs. In addition, these are known Plastics elements like the conventional paving stones in one Mortar bed lined up, so that a (largely) flat driving or treading surface arises, which is associated with a considerable amount of processing.

Die FR-A-2 550 247 offenbart ein Pflasterelement aus Kunststoff, das eine durchgehende obere Wandfläche hat, an deren Unterseite zahlreiche nebeneinanderliegende, miteinander verbundene, unten offene Zellen angeformt sind. FR-A-2 550 247 discloses a plaster element made of plastic, the one has continuous top wall surface, numerous on the underside Adjacent, interconnected, open cells formed at the bottom are.

Die EP-A-0 400 158 offenbart eine Rasengitterplatte mit in Wabenstruktur angeordneten sechseckigen Zellen, bei der am Umfang zwischen den Randzellen Zwischenräume frei bleiben, in denen Plattenabschnitte vorhanden sind, die als zusätzliches Verbindungselement zwischen zwei zusammengesetzen Rasengitterplatten dienen, wobei im Bereich der Plattenabschnitte die Höhe der Zellen verringert ist.EP-A-0 400 158 discloses a grass panel with a honeycomb structure arranged hexagonal cells, with the circumference between the marginal cells Spaces remain free in which there are plate sections that are as put additional connecting element between two Grass grid panels serve, the height of the in the area of the panel sections Cells is decreased.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein aus Kunststoff bestehendes Pflasterelement zur Befestigung von Bodenflächen mit einer durchgehenden oberen Wandfläche anzugeben, welches mit erheblich geringerem Arbeitsaufwand so zu verlegen ist, daß eine weitestgehend ebene Tritt/Fahrfläche oder Markierungslinie aus einer Vielzahl dieser Pflasterelemente entsteht. Außerdem soll das Pflasterelement bei einem verhältnismäßig geringen Materialeinsatz eine große Festigkeit aufweisen.The present invention has for its object a plastic existing paving element for fastening floor surfaces with a to indicate continuous top wall surface, which with significantly less The workload is to be laid in such a way that a largely level tread / driving surface or marking line from a variety of these patch elements. Moreover the plaster element is a with a relatively small amount of material have great strength.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the characterizing part of claim 1 specified features solved. Advantageous developments of the invention are in marked the subclaims.

Das erfindungsgemäße Pflasterelement enthält mehrere, beispielsweise 10 bis 20 nebeneinanderliegende, miteinander verbundene, unten offene Zellen, die an der Unterseite einer oberen Wand angeformt sind. Am Umfang des Pflasterelementes bleiben bevorzugt dadurch, daß die Zellen versetzt zueinander angeordnet sind - ohne daß die Erfindung hierauf beschränkt ist - Zwischenräume frei, die ganz oder teilweise von Rippen überbrückt werden, die unten an an die Zwischenräume angrenzenden Randzellen angeformt sind. Dabei kann der größte Teil oder der gesamte Zwischenraum (im Grundriß betrachtet) durch eine durchgehende Platte überbrückt bzw. geschlossen sein, wodurch das erfindungsgemäße Pflasterelement eine besonders hohe Stabilität erhält. Die in die Zwischenräume hineinragenden Rippen können jedoch auch jeweils aus einem oder mehreren miteinander verbundenen schmalen Stegen bestehen, wodurch das Pflasterelement ebenfalls erheblich versteift wird. The plaster element according to the invention contains several, for example 10 to 20 juxtaposed, interconnected cells, open at the bottom, which on the Bottom of an upper wall are molded. On the circumference of the pavement element remain preferred because the cells are staggered - without the invention being limited to this - spaces that are entirely or partially bridged by ribs that attach to the gaps below adjacent marginal cells are formed. The largest part or the entire space (viewed in plan) through a continuous plate be bridged or closed, as a result of which the plaster element according to the invention receives a particularly high stability. Those protruding into the gaps However, ribs can also consist of one or more each other connected narrow webs exist, which also the plaster element is significantly stiffened.

Erfindungsgemäß ist ferner vorgesehen, daß an den Zwischenräumen benachbarten Randzellen bereichsweise untere Wandstreifen weggeschnitten bzw. ausgespart sind, wobei diese ausgesparten Wandstreifen beim Zusammensetzen zweier Pflasterelemente das Eintreten der angeformten Rippen des jeweils anderen Pflasterelementes ermöglichen. D.h., daß zumindest auf einer solchen Breite untere Randzellen-Wandstreifen ausgespart sind, die der Breite der unten an den Zwischenräumen angeformten Rippen entspricht.According to the invention it is further provided that at the gaps adjacent edge cells cut away sections of lower wall strips or are recessed, these being recessed Wall strips when putting together two pavement elements Enter the molded ribs of the other paving element enable. That is, at least on one Wide lower marginal cell wall strips are spared that the Width corresponds to the ribs formed on the spaces below.

Die Verbindung einer oberen Wandfläche mit den darunter liegenden Zellen, die bevorzugt so ausgebildet sind, daß aneinander angrenzende Zellen gemeinsame wandflächen haben, bringt bereits eine große Steifigkeit und Stabilität des Pflasterelementes mit sich. Das Pflasterelement hat sowohl eine hohe Biegefestigkeit als auch ein hohes Widerstandsmoment gegen Torsion bzw. Verwindung. Die Stabilität wird zusätzlich dadurch erhöht, daß die am Umfang befindlichen Zwischenräume ganz oder teilweise von Rippen überbrückt werden, die noch zwei zusätzliche Funktionen ausüben.The connection of an upper wall surface with the ones below Cells, which are preferably designed so that one another adjacent cells already have common wall surfaces a great rigidity and stability of the paving element with yourself. The paving element has both a high flexural strength as well as a high moment of resistance to torsion or torsion. The stability is additionally increased in that the All or part of the gaps on the circumference of Ribs are bridged, which have two additional functions exercise.

Zum einen verhindern die Rippen, daß das Pflasterelement zu weit in einen beispielsweise aus Sand bestehenden Untergrund eindringt, indem die Rippen verhältnismäßig großflächige Auflager bilden, was vor allem dann der Fall ist, wenn sie eine Plattenform haben und im wesentlichen die gesamte Fläche der Zwischenräume überbrücken. Wie bereits erwähnt, kann es in Abhängigkeit vom Untergrund jedoch auch vorteilhaft sein, die Rippen als schmale Stege auszuführen, was vor allem dann angebracht sein kann, wenn ein Einsinken der Plasterelemente in den Boden nicht zu befürchten ist. Firstly, the ribs prevent the paving element from becoming too wide penetrates, for example, a subsoil made of sand, by supporting the ribs relatively large area form, which is especially the case if they have a plate shape have and essentially the entire area of the gaps bridge. As mentioned earlier, it can be dependent from the subsurface, however, the ribs can also be advantageous to carry out narrow webs, which is particularly appropriate can if the plaster elements do not sink into the ground is to be feared.

Die am Umfang des Pflasterelementes ausgebildeten Zwischenräume zwischen Randzellen, die dort vorgesehenen Rippen und die Aussparungen am unteren Rand der benachbarten Randzellen ermöglichen es zudem auf einfache Weise, eine Vielzahl von Pflasterelementen gleicher Bauart auf einfache Weise lückenlos zusammen zu setzen, indem jeweils zwei Pflasterelement versetzt zueinander so zusammengefügt werden, daß die Rippen des einen Pflasterelementes in die Aussparungen am unteren Rand der Randzellen des anderen Pflasterelementes eingeführt werden, bis die zwei Pflasterelemente aneinander anliegen. Dadurch daß die Oberseite der Rippen geringfügig höher liegt als die Unterkante der zugeordneten Zellenwände (in der Größenordnung von 10tel Millimeter) entsteht eine Klemmwirkung zwischen den benachbarten Pflasterelementen, so daß diese fest zusammenhalten. Das Einführen der Rippen unter die Randzellen des benachbarten Pflasterelementes kann dadurch erleichtert werden, daß die Oberseite der Rippen sich zum freien Rand hin geringfügig neigt, so daß die Rippen querschnittlich eine leichte Keilform haben und glatt unter die Randzellen eintreten können und erst im Verlaufe des Zusammenschiebens bei beiden Pflasterelementen auf die unteren Randkanten der Zellen auflaufen.The spaces formed on the circumference of the paving element between marginal cells, the ribs provided there and the recesses allow at the bottom of the neighboring marginal cells it also easily a variety of pavement elements same design in a simple way without gaps to be set by staggering two paving elements to each other be assembled so that the ribs of a plaster element into the recesses at the bottom of the marginal cells of the other patch element are inserted until the two Put the patch elements together. Because the top the ribs are slightly higher than the lower edge of the assigned one Cell walls (on the order of 10th millimeters) there is a clamping effect between the adjacent paving elements, so that they stick together. Introducing the ribs under the marginal cells of the adjacent paving element can be facilitated by the fact that the top of the Ribs tends slightly towards the free edge, so that the Ribs have a slight wedge shape in cross section and are smooth can enter under the marginal cells and only in the course of Pushing together the two pavement elements onto the lower ones Border edges of the cells run open.

Dabei kann auch vorgesehen sein, daß die Rippen in der Endposition unter den Randkanten der Randzellen einrasten, wobei die Rippen mit kleinen Rastnuten versehen sein können.It can also be provided that the ribs in the end position engage under the marginal edges of the marginal cells, the Ribs can be provided with small locking grooves.

Die Zellen haben bevorzugt eine sechseckige Form und sind wabenförmig miteinander verbunden, was zu einer besonders hohen Stabilität des Pflasterelementes führt. Die Zellen können jedoch auch eine andere Form, wie die eines Rechtsecks oder Quadrats, haben. The cells preferably have a hexagonal shape and are honeycomb-shaped linked together, resulting in a particularly high Stability of the paving element leads. However, the cells can another shape, like a rectangle or square, to have.

Das Pflasterelement hat in weiterer Ausgestaltung der Erfindung bevorzugt eine langgestreckte, schmale Form, wobei das Verhältnis Länge zu Breite bevorzugt etwa 3 : 1 beträgt. Dabei können zwei Reihen von Zellen vorgesehen sein, wobei in Längsrichtung des Pflasterelementes aufeinanderfolgende Zellen jeweils in Breitenrichtung um eine halbe Zelle zueinander versetzt angeordnet sein können. Bei dieser Ausgestaltung befinden sich an den Längsrändern des Pflasterelementes abwechselnd Zellen und Zwischenräume, die die Form einer halben Zelle haben, was insbesondere dann zweckmäßig ist, wenn die Zellen eine sechseckige Form mit gleichlangen Seiten haben.In a further embodiment of the invention, the paving element has preferably an elongated, narrow shape, the ratio Length to width is preferably about 3: 1. You can two rows of cells may be provided, being longitudinal of the patch element successive cells each in Width direction offset by half a cell to each other could be. In this configuration, the Longitudinal edges of the paving element alternating cells and spaces, which have the shape of a half cell, which in particular then it is useful if the cells have a hexagonal shape with sides of equal length.

An den Stirnflächen des Pflasterelementes befindet sich jeweils ein dreieckiger Zwischenraum, in den auch eine (oder mehrere) Rippen zur Versteifung, als Auflager und zur Befestigung an einem anschließenden Pflasterelement hineinragt.Is located on the end faces of the plaster element a triangular space in which one (or more) Ribs for stiffening, as supports and for fastening a subsequent plaster element protrudes.

Das Pflasterelement wird bevorzugt im Spritzgußverfahren hergestellt. Wenn eine mehrteilige Spritzgußform zur Ausbildung der Zellen verwendet wird, können nicht-benachbarte Zellen zur Erhöhung der Stabilität des Pflasterelementes zum unteren Rand hin eine zunehmende Wandstärke erhalten, was durch Zwangsentformung oder zusammenklappbare Formkerne möglich ist.The paving element is preferably produced by injection molding. If a multi-part injection mold to form the Cells used can be non-adjacent cells Increasing the stability of the paving element towards the lower edge towards an increasing wall thickness, which is due to forced demolding or collapsible mold cores is possible.

Das erfindungsgemäße Pflasterelement benötigt verhältnismäßig wenig Kunststoffmaterial und ist billig herstellbar. Das Pflasterelement ist schnell und einfach bevorzugt mit weiteren identischen Pflasterelementen zusammensetzbar, wobei die Pflasterelemente fest zusammenhalten, so daß auch große Flächen in kurzer Zeit mit geringem Arbeitsaufwand mit den erfindungsgemäßen Pflasterelementen befestigt werden können. Die am Boden der Zwischenräume (am Umfang der Pflasterelemente) angeformten Rippen oder Platten führen zu einer sehr hohen Stabilität und Festigkeit des Pflasterelementes, verhindern dessen unkontrolliertes Eindringen in den Untergrund und dienen der sicheren Befestigung der Pflasterelemente untereinander. The patch element according to the invention requires relatively little plastic material and is cheap to manufacture. The pavement element is quickly and easily preferred with other identical ones Patch elements can be assembled, the patch elements hold tightly together so that even large areas in short time with little work with the invention Pavement elements can be attached. The one at the bottom of the Gaps formed (on the circumference of the pavement elements) Ribs or plates lead to very high stability and Strength of the paving element, prevent its uncontrolled Penetrate underground and serve the safe Fastening the paving elements to each other.

Es wird zunächst auf Fig. 1 Bezug genommen. Das dort etwa zur Hälfte abgebildete Pflasterelement 1 enthält zwei Längsreihen von unten offenen, sechseckigen Zellen 2, die wabenartig miteinander verbunden sind, indem einander benachbarte Zellen gemeinsame Zellenwände (z.B. 3) haben. Die Zellen 2 sind damit in Längsrichtung jeweils um eine halbe Zellenbreite seitlich zueinander versetzt.Reference is first made to FIG. 1. That about there Half of the plaster element 1 shown contains two longitudinal rows from below open, hexagonal cells 2, which are like a honeycomb are connected by adjacent cells have common cell walls (e.g. 3). The cells 2 are so in the longitudinal direction laterally by half a cell width offset from each other.

An ihrer Oberseite sind die Zellen 2 einstückig an eine durchgehende obere Wand (siehe Fig. 2 und 3) angeformt, die im zusammengesetzten Zustand mehrerer Pflasterelemente 1 eine durchgehende Tritt- oder Fahrfläche oder Markierungslinie bildet.At the top, the cells 2 are integral with a continuous one upper wall (see Fig. 2 and 3) formed in the composite State of several paving elements 1 a continuous Stepping or driving surface or marking line forms.

Am Umfang des Pflasterelementes 1 befinden sich im Wechsel mit den Zellen 2 Zwischenräume 5, die die Form und Größe einer halben Zelle 2 haben. In der dargestellten Ausführungsform entstehen diese Zwischenräume durch die seitlich versetzte Anordnung der wabenartigen Zellen 2. In einer alternativen Ausführungsform, die ebenfalls im Rahmen der Erfindung liegt und bei der die Zellen beispielsweise eine quadratische Form haben können, können die am Umfang bzw. Rand des Pflasterelementes vorgesehenen Zwischenräume auch dadurch entstehen, daß einzelne Zellen weggelassen werden.The circumference of the plaster element 1 is alternated with the cells 2 spaces 5, which the shape and size of a have half cell 2. In the illustrated embodiment these gaps arise from the laterally offset Arrangement of the honeycomb cells 2. In an alternative Embodiment, which is also within the scope of the invention and where the cells have a square shape, for example can, the on the circumference or edge of the paving element intended gaps also arise from the fact that individual Cells are omitted.

An den beiden Stirnseiten des Pflasterelementes 1 ist ein dreieckiger Zwischenraum 6 ausgebildet, bedingt durch die Anordnung von zwei nebeneinanderliegenden Reihen von Zellen 2. Es versteht sich, daß bei einer größeren Anzahl von Längsreihen der Zellen 2 entsprechend mehr dreieckige Zwischenräume 6 entstehen.There is a triangular on the two end faces of the plaster element 1 Space 6 formed due to the arrangement of two adjacent rows of cells 2. It understands that with a larger number of longitudinal rows of cells 2 correspondingly more triangular spaces 6 arise.

Die Zwischenräume 5 und 6 sind am Boden des Pflasterelementes 1 größtenteils von plattenförmigen Rippen 7 und 8 überbrückt bzw. geschlossen. Die Rippen 7 und 8 sind am unteren Ende der Zellenwände 9 und 10 der an die Zwischenräume 5 und 6 angrenzenden Zellen 2 angeformt.The spaces 5 and 6 are at the bottom of the paving element 1 mostly bridged by plate-shaped ribs 7 and 8 or closed. The ribs 7 and 8 are at the lower end of the cell walls 9 and 10 of those adjacent to the spaces 5 and 6 Cells 2 molded.

Die Rippen 7 haben eine Sechseckform und erstrecken sich mit ihrer mit den seitlich angrenzenden Zellen verbundenen Kante 11 maximal über die Hälfte einer Seitenwand 12 der Zellen, und zwar aus dem nachstehend erläuterten Grund.The ribs 7 have a hexagonal shape and extend with its edge 11 connected to the laterally adjacent cells at most over half of a side wall 12 of the cells, namely for the reason explained below.

An den an die Zwischenräume 5 angrenzenden Zellen ist der untere Randstreifen der Zellenwand weggeschnitten bzw. ausgespart, und zwar durchgehend von einem Punkt 13 einer Rippe bis zu dem entsprechenden Punkt 14 der nächsten Rippe. Damit ist der unteren Randstreifen auf eine Breite b1 weggeschnitten, die mindestens so groß ist wie die maximale Breite b2 der Rippen 7 (in Längsrichtung des Pflasterelementes 1).At the cells adjacent to the interstices 5 is the lower one Edge strips of the cell wall cut away or cut out, and continuous from a point 13 of a rib to that corresponding point 14 of the next rib. That is the bottom Edge strips cut to a width b1, the minimum is as large as the maximum width b2 of the ribs 7 (in Longitudinal direction of the paving element 1).

Die Rippen 7 und die Aussparungen 15 sind dazu vorgesehen, zwei Pflasterelemente 1 und 1' auf einfache Weise seitlich so zusammen zu setzen, daß ein lückenloser, fester Zusammenhalt gewährleistet ist. Hierzu werden die Pflasterelemente in Längsrichtung so gegeneinander versetzt, daß die Rippen 7 in die Aussparungen 15 (unter den zugehörigen Zellen 2) eintreten, bis die Zellenwände aneinander anliegen.The ribs 7 and the recesses 15 are provided for two Pavement elements 1 and 1 'in a simple way laterally together to set that a complete, solid cohesion is guaranteed. For this purpose, the paving elements in the longitudinal direction so offset against each other that the ribs 7 in the recesses 15 (under the associated cells 2) until the Cell walls lie against each other.

Die Rippen 7 haben eine etwas geneigt verlaufende Oberseite, wie die Figuren 2 und 3 erkennen lassen. An ihrem freien Ende liegt die Oberseite der Rippen 7 geringfügig unterhalb der Unterkante der Zellenwände der Aussparungen 15, so daß die Rippen 7 leicht in die Aussparungen eingeführt werden können. Anschließend steigt die Oberseite der Rippen 7 leicht an, wodurch die Rippen 7 im Querschnitt eine leichte Keilform erhalten. Die Oberseite steigt auf eine Höhe an, die geringfügig oberhalb der Unterkante der Zellenwände im Bereich der Aussparungen 15 liegt.The ribs 7 have a slightly inclined top, such as Figures 2 and 3 can be seen. Is at its free end the top of the ribs 7 slightly below the bottom edge the cell walls of the recesses 15 so that the ribs 7 are light into which recesses can be inserted. Subsequently the top of the ribs 7 rises slightly, causing the ribs 7 obtained a slight wedge shape in cross section. The top rises to a height slightly above the lower edge the cell walls are in the area of the cutouts 15.

Dies bedeutet, daß beim (seitlichen) Zusammensetzen zweier Pflasterelemente 1 und 1' die Unterkanten der Zellenwände an den Aussparungen 15 allmählich auf die Oberseite der Rippen 7 auflaufen, wodurch eine leichte Klemmwirkung entsteht. Im Bereich der Endstellung, in der die Seitenwände der benachbarten Zellen 2 und 2' aneinander anliegen, befindet sich in der Oberseite der Rippen 7 eine sich über die gesamte Breite erstreckende Nut 16, in die die Unterkante der Zellenwand 2' einrastet. Durch geeignete Form der Nutwände kann das Verrasten in der Weise geschehen, daß die so zusammengesetzten Pflastersteine nicht mehr zerstörungsfrei voneinander getrennt werden können. Dies läßt sich dadurch erreichen, daß die dem benachbarten Pflasterelement zugewandte Nutfläche im wesentlichen vertikal verläuft.This means that when (laterally) putting two Patch elements 1 and 1 'the lower edges of the cell walls on the Cutouts 15 gradually onto the top of the ribs 7 run up, which creates a slight clamping effect. In the area the end position in which the side walls of the neighboring Cells 2 and 2 'abut each other, is in the top the ribs 7 an extending over the entire width Groove 16 into which the lower edge of the cell wall 2 'engages. By a suitable shape of the groove walls, the locking in the Way happen that the cobbles so assembled can no longer be separated from one another without destruction. This can be achieved in that the neighboring Groove surface facing plaster element essentially vertically runs.

Es kann aber auch vorgesehen sein, daß die Verrastung zerstörungsfrei lösbar ist, indem die Nut die Form einer flachen Wanner erhält. But it can also be provided that the latching is non-destructive can be solved by making the groove the shape of a flat Wanner receives.

An den Stirnseiten des Pflasterelementes 1 tritt auf entsprechende Weise die Rippe 8 in eine entsprechende Aussparung 17 am unteren Rand der benachbarten Zelle ein. Auch hier hat die Rippe 8 querschnittlich eine leichte Keilform mit einer Rastnut, die in einem kurzen Abstand vor den Zellenwänden 10 liegt.On the end faces of the plaster element 1 occurs on corresponding Way the rib 8 in a corresponding recess 17 on bottom of the neighboring cell. Here too the rib has 8 a slight wedge shape in cross-section with a locking groove is a short distance from the cell walls 10.
