Description

Die Erfindung betrifft ein Belagselement, bestehend aus einer elastischen Matte, die von in Kunstharz eingebettetem Gummigranulat gebildet ist, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a covering element consisting of an elastic mat which is formed by rubber granules embedded in synthetic resin, according to the preamble of patent claim 1.

Aus der DE 39 02 419 A1 ist ein Bodenbelag, bestehend aus einem Gummigranulat bekannt, welches in Kunstharz eingebettet ist. Dieser Bodenbelag ist insbesondere als Reitplatzbelag vorgesehen. Zur Erzielung einer für Pferde angenehmen Oberfläche ist dieser Bodenbelag mit Sägespänen belegt. Diese werden jedoch insbesondere beim Laufen und Springen der Pferde weg gedrückt, so daß die Sägespäne von Zeit zu Zeit eingeebnet werden müssen. Dieser Bodenbelag hat sich in der Praxis gut bewährt und bildet den Ausgangspunkt der vorliegenden Erfindung.From the DE 39 02 419 A1 is a floor covering, consisting of a rubber granules known, which is embedded in synthetic resin. This floor covering is intended in particular as Reitplatzbelag. To achieve a comfortable surface for horses this floor covering is covered with sawdust. However, these are pressed away especially when running and jumping horses, so that the sawdust must be leveled from time to time. This floor covering has proven itself well in practice and forms the starting point of the present invention.

Der Erfindung liegt die Aufgabe zugrunde, ein Belagselement der eingangs genannten Art zu schaffen, welches sich durch eine hohe Abriebfestigkeit bei gleichzeitig hohem Gehkomfort auszeichnet.The invention has for its object to provide a covering element of the type mentioned, which is characterized by a high abrasion resistance at the same time high walking comfort.

Diese Aufgabe wird erfindungsgemäß mit Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with features of claim 1.

Das Belagselement gemäß Anspruch 1 besteht aus einer elastischen Matte, die für den gewünschten angenehmen Gehkomfort sorgt. Diese elastische Matte besteht aus einem in Kunstharz eingebettetem Gummigranulat, welches vorzugsweise von recyceltem Altgummi, insbesondere Autoreifen gebildet wird. Dieses Gummigranulat sorgt für die gewünschte Elastizität der Matte. In Folge der Einbettung des Gummigranulats in das Kunstharz ergeben sich an den Korngrenzen des Gummigranulats erhebliche Dichtegradienten, die für eine günstige, mechanische Dämpfung der Matte sorgen. Die beim Begehen der Matte eingebrachte mechanische Energie wird in Folge dieser Dämpfung größtenteils dissipiert. Zur Erzielung einer ausreichend hohen Abriebfestigkeit sind an der Oberfläche der Matte Steine bzw. mineralische Korngemische als Deckschicht vorgesehen. Diese Deckschicht besitzt eine ausreichend hohe Härte, um die gewünschte Abriebfestigkeit zu erzielen. Außerdem sorgt die Deckschicht für einen günstigen optischen Eindruck des Belagselements, insbesondere bei Verlegung im Freien. Das Belagselement sieht dabei aus wie eine lose Steinschüttung, wobei im Gegensatz zur echten Steinschüttung die Steine bzw. mineralischen Korngemische im Kunstharz der Matte fest verankert sind. Die Deckschicht ist daher unverrückbar, so daß sie beim Begehen des Belagselements nicht verdrängt wird. Auf diese Weise ist sichergestellt, daß im Gehbereich keinerlei Mulden entstehen, die von Zeit zu Zeit ausgeglichen werden müßten. Das Belagselement ist dauerhaft funktionstüchtig und muß bis auf eine ggf. notwendige oberflächliche Reinigung nicht gepflegt werden. Eine oberflächliche Reinigung ist außerdem besonders einfach durchzuführen, da sich die Steine an der Oberfläche des Belagselements nicht bewegen können.The covering element according to claim 1 consists of an elastic mat, which ensures the desired pleasant walking comfort. This elastic mat consists of a resin embedded in rubber granules, which is preferably made of recycled waste rubber, especially car tires. This rubber granulate provides the desired elasticity of the mat. As a result of the embedding of the rubber granules in the resin resulting in the grain boundaries of the rubber granulate considerable density gradients, which provide a favorable, mechanical damping of the mat. The introduced when walking the mat mechanical energy is largely dissipated as a result of this damping. To achieve a sufficiently high abrasion resistance, stones or mineral grain mixtures are provided on the surface of the mat as a cover layer. This cover layer has a sufficiently high hardness to achieve the desired abrasion resistance. In addition, the cover layer provides a favorable visual impression of the covering element, especially when laying outdoors. The flooring element looks like a loose riprap, in contrast to the real riprap stones or mineral grain mixtures are firmly anchored in the resin of the mat. The cover layer is therefore immovable, so that it is not displaced when walking on the covering element. In this way it is ensured that no troughs arise in the walking area, which would have to be compensated from time to time. The flooring element is permanently functional and need not be maintained except for a possibly necessary superficial cleaning. A superficial cleaning is also particularly easy to perform because the stones can not move on the surface of the covering element.

Zur Erzielung einer möglichst guten Elastizität des Belagselements ist es gemäß Anspruch 2 vorteilhaft, wenn die Matte mindestens zwei Siebfraktionen Gummigranulat mit wesentlich verschiedener Korngröße aufweist. Auf diese Weise ergibt sich ein besonders hoher Anteil an Gummigranulat in der Matte, da sich die Gummigranulatteilchen der kleineren Fraktion stets in die Hohlräume zwischen den Körnern der groben Fraktion setzen. Dies führt zu einer Verminderung des Kunstharzanteils, so daß das Bodenbelagselement im wesentlichen von den elastischen Eigenschaften des Gummigranulats bestimmt ist.To achieve the best possible elasticity of the covering element, it is advantageous according to claim 2, if the mat has at least two sieve fractions rubber granules with significantly different particle size. This results in a particularly high proportion of rubber granulate in the mat, since the rubber granulate particles of the smaller fraction always settle in the cavities between the grains of the coarse fraction. This leads to a reduction of the resin content, so that the flooring element is essentially determined by the elastic properties of the rubber granulate.

Zur Erzielung einer besonders hohen Elastizität ist es gemäß Anspruch 3 vorteilhaft, wenn mindestens eine der Siebfraktionen ein Gummimehl ist. Gummimehl ist derart feinkörnig, daß es sich besonders gut in die Lücken zwischen dem groben Gummigranulat setzen kann. Auf diese Weise ergibt sich ein besonders geringer Kunstharzanteil.To achieve a particularly high elasticity, it is advantageous according to claim 3, if at least one of the sieve fractions is a rubber dust. Rubber flour is so fine-grained that it can sit particularly well in the gaps between the coarse rubber granulate. In this way, a particularly low proportion of synthetic resin results.

Für die Deckschicht haben sich gemäß Anspruch 4 Steine aus Kies bzw. Schotter bewährt. Die Wahl der Deckschicht und insbesondere die konkrete mineralische Zusammensetzung der Deckschicht werden in der Regel unter optischen Gesichtspunkten bestimmt, so daß sich das Bodenbelagselement gut in die Umgebung einfügt. Bevorzugt wird deshalb ein Naturstein als Deckschicht eingesetzt.For the top layer stones of gravel or gravel have been proven according to claim 4. The choice of the top layer and in particular the concrete mineral composition of the top layer are usually determined from an optical point of view, so that the flooring element fits well into the environment. Therefore, a natural stone is preferably used as a cover layer.

Alternativ ist es gemäß Anspruch 5 günstig, die mineralischen Korngemische aus Glas, Beton, Ton und/oder Ziegel zu bilden. Dies Materialien können sehr einfach geformt werden, um die gewünschte Oberflächenstruktur zu erzielen. Beispielsweise können diese Korngemische kugelförmig hergestellt werden.Alternatively, it is advantageous according to claim 5, to form the mineral grain mixtures of glass, concrete, clay and / or brick. These materials can be molded very easily to achieve the desired surface texture. For example, these grain mixtures can be made spherical.

Um eine gute Festigkeit der Deckschicht zu erreichen, ist es gemäß Anspruch 6 günstig, wenn diese beim Aushärten des Kunstharzes mit der Matte verpreßt ist. Damit kann das Kunstharz die Deckschicht regelrecht umfließen, so daß sich eine innige Verbindung der Deckschicht mit dem Kunstharz ergibt. Ein späteres Lösen der Deckschicht ist auf diese Weise nicht mehr möglich. Um zu verhindern, daß das Kunstharz auch die Oberfläche der Deckschicht überdeckt und damit das optische Erscheinungsbild des Belagselements negativ beeinflußt, ist insbesondere daran gedacht, in eine Preßform zunächst eine Pufferschicht, insbesondere feinkörnigen Sand zu schütten, auf die dann die Deckschicht gefüllt wird. Anschließend wird das mit dem Kunstharz vermischte Gummigranulat eingefüllt und das gesamte Sandwich anschließend verpreßt. Die vom Sand gebildete Pufferschicht verhindert dabei, daß das Kunstharz über die Deckschicht hinausfließen kann, das Kunstharz wird vielmehr auf Höhe der Deckschicht zurückgehalten. Die Pufferschicht kann selbstverständlich mehrfach genutzt werden. Außerdem ist auch die umgekehrte Anordnung vorstellbar, bei der die Pufferschicht zuletzt eingefüllt wird, gegen die dann ein Stempel drückt.In order to achieve good strength of the cover layer, it is advantageous according to claim 6, if this is pressed during curing of the resin with the mat. Thus, the resin can flow around the cover layer downright, so that there is an intimate connection of the cover layer with the resin. A later release of the cover layer is no longer possible in this way. In order to prevent the synthetic resin also covering the surface of the covering layer and thus negatively influencing the visual appearance of the covering element, it is particularly conceivable first to pour into a pressing mold a buffer layer, in particular fine-grained sand, onto which the covering layer is then filled. Subsequently, the rubber granules mixed with the synthetic resin are filled in and the entire sandwich is then pressed. The one formed by the sand Buffer layer prevents that the synthetic resin can flow beyond the cover layer, the resin is rather retained at the level of the cover layer. Of course, the buffer layer can be used multiple times. In addition, the reverse arrangement is conceivable in which the buffer layer is filled last, against which then presses a stamp.

Zur Erzielung einer effektiven Entwässerung des Belagselements ist es gemäß Anspruch 7 vorteilhaft, wenn das Belagselement wasserdurchlässig ist. Dies kann beispielsweise durch eine großporige Bauweise der Matte realisiert werden, so daß in der Matte viele Gasporen enthalten sind, die sich zu durchgängigen Kanälen verbinden. Diese Kanäle können von Regenwasser sehr einfach durchdrungen werden. Da auf diese Weise eine großflächige Entwässerung des Belagselements möglich ist, kann das Regenwasser direkt im darunterliegenden Boden versickern. Auf diese Weise wird die Fläche, auf der das Bodenbelagselement aufgelegt wird, nicht versiegelt, was sich beispielsweise vorteilhaft auf zu entrichtende Abwassergebühren auswirkt.To achieve an effective drainage of the covering element, it is advantageous according to claim 7, when the covering element is permeable to water. This can be realized for example by a large-pore construction of the mat, so that in the mat many gas pores are included, which connect to continuous channels. These channels can be easily penetrated by rainwater. Since a large-scale drainage of the covering element is possible in this way, the rainwater can seep directly into the underlying soil. In this way, the surface on which the flooring element is placed, not sealed, which, for example, advantageous to pay to wastewater charges.

Alternativ ist es gemäß Anspruch 8 günstig, wenn die elastische Matte wasserundurchlässig ist. Auf diese Weise kann das Bodenbelagselement dazu genutzt werden, eine Fläche bewußt zu versiegeln, um beispielsweise einen darunter liegenden Raum vor Regenwasser zuverlässig zu schützen. Das Bodenbelagselement kann in diesem Fall vorteilhaft als Flachdach eingesetzt werden.Alternatively, it is favorable according to claim 8, when the elastic mat is impermeable to water. In this way, the flooring element can be used to deliberately seal a surface, for example, to reliably protect an underlying space from rainwater. The flooring element can be advantageously used in this case as a flat roof.

Um die Haftung zwischen der Matte und der Deckschicht zu verbessern, ist es gemäß Anspruch 9 vorteilhaft, wenn die Matte Vertiefungen aufweist, in die die Deckschicht eindringt. Auf diese Weise kann die Verbindung zwischen der Deckschicht und der Matte auch größeren Scherkräften problemlos standhalten, die beispielsweise beim Befahren des Belagselements mit einem Kraftfahrzeug auftreten können. Insbesondere bei wasserundurchlässiger Matte ergibt sich in den Vertiefungen ein Wasserreservoir, das die Deckschicht über lange Zeit feucht hält. Diese Maßnahme ist bei bestimmten mineralischen Deckschichten vorteilhaft, die im feuchten Zustand einen besseren optischen Eindruck vermitteln. Vorzugsweise werden die Vertiefungen in diesem Fall derart ausgebildet, daß diese bis auf relativ dünne Stege nahezu die gesamte Fläche des Belagselements ausmachen. Damit ergibt sich eine gleichmäßige Befeuchtung der Deckschicht.In order to improve the adhesion between the mat and the cover layer, it is advantageous according to claim 9, if the mat has recesses into which the cover layer penetrates. In this way, the connection between the cover layer and the mat can easily withstand even greater shearing forces, which can occur, for example, when driving on the covering element with a motor vehicle. Especially with water-impermeable mat results in the wells a water reservoir that keeps the cover layer moist for a long time. This measure is advantageous for certain mineral cover layers, which give a better visual impression in the wet state. Preferably, the recesses are formed in this case such that they make up on relatively thin webs almost the entire surface of the covering element. This results in a uniform moistening of the topcoat.

Schließlich ist es gemäß Anspruch 10 günstig, wenn die elastische Matte unterseitig Noppen bzw. Stege aufweist. Diese Strukturierung der Unterseite der Matte sorgt für einen festen Halt der Matte auf dem Untergrund, auf dem sie aufliegt, wodurch ein Verrutschen des Belagselements zuverlässig verhindert wird.Finally, it is favorable according to claim 10, when the elastic mat has knobs or webs on the underside. This structuring of the underside of the mat ensures a firm hold of the mat on the substrate on which it rests, whereby a slippage of the covering element is reliably prevented.

Figur 1 zeigt eine räumliche Darstellung eines Belagselements 1. Dieses Belagselement 1 besteht aus einer elastischen Matte 2 und einer Deckschicht 3. Die elastische Matte 2 wird von einem Gummigranulat 4 gebildet, welches zwei unterschiedliche Siebfraktionen aufweist. Die grobe Fraktion des Gummigranulats 4 hat eine Korngröße von ca. 5 mm bis 10 mm, während die feine Fraktion ein Gummimehl mit einer Korngröße von unter 1 mm ist. Durch die Mischung der beiden Fraktionen ergibt sich ein besonders hoher Gummianteil in der Matte 2. Das Gummigranulat 4 ist in einem Kunstharz 5 eingebettet, um den gewünschten elastischen Körper zu bilden.1 shows a spatial representation of a covering element 1. This covering element 1 consists of an elastic mat 2 and a cover layer 3. The elastic mat 2 is formed by a rubber granulate 4, which has two different sieve fractions. The coarse fraction of the rubber granules 4 has a grain size of about 5 mm to 10 mm, while the fine fraction is a rubber powder with a grain size of less than 1 mm. The mixture of the two fractions results in a particularly high proportion of rubber in the mat 2. The rubber granulate 4 is embedded in a synthetic resin 5 to form the desired elastic body.

Die Deckschicht 3 besteht aus Steinen, die in das Kunstharz 5 eingebettet sind, dieses jedoch überragen. Auf diese Weise ergibt sich eine kunstharzfreie Deckschicht 3 aus rein mineralischem Material. Von oben betrachtet sieht man im wesentlichen nur die Steine 6 der Deckschicht 3, so daß der darunter liegende Aufbau der Matte 2 dem Betrachter verborgen bleibt.The cover layer 3 consists of stones that are embedded in the synthetic resin 5, but this project beyond. In this way, there is a synthetic resin-free cover layer 3 of pure mineral material. Seen from above, one sees essentially only the stones 6 of the cover layer 3, so that the underlying structure of the mat 2 remains hidden from the viewer.

Die Figur 2 zeigt eine alternative Ausführungsform eines Belagselements 1, wobei die Deckschicht 3 zur besseren Übersichtlichkeit von der elastischen Matte 2 getrennt dargestellt ist. Um die Details der elastischen Matte 2 besser erkennen zu können, ist das Gummigranulat 4 nicht im Detail dargestellt. Die elastische Matte 2 ist unabhängig von dieser Darstellung aus einem Gummigranulat 4 aufgebaut, die in Kunstharz 5 gebunden ist.FIG. 2 shows an alternative embodiment of a covering element 1, the covering layer 3 being shown separated from the elastic mat 2 for better clarity. In order to better recognize the details of the elastic mat 2, the rubber granulate 4 is not shown in detail. The elastic mat 2 is constructed independently of this representation of a rubber granules 4, which is bound in synthetic resin 5.

Die elastische Matte 2 weist oberseitig Vertiefungen 7 auf, die von Stegen 7a voneinander getrennt sind. Die Vertiefungen 7 haben eine quadratische Form, wobei jede andere Form geeignet ist, ohne die technische Wirkung der Vertiefungen 7 zu beeinträchtigen. Die Vertiefungen 7 nehmen gegenüber den Stegen 7a eine wesentlich größere Fläche des Belagselements 1 ein, so daß die elastische Matte 2 - von oben betrachtet - fast nur aus Vertiefungen 7 besteht. Füllen sich diese Vertiefungen 7 mit Wasser, beispielsweise durch Besprengen des Belagselements 1 von oben, so bleibt dieses in den Vertiefungen 7 relativ lange stehen und befeuchtet damit die Deckschicht 3. Da die Stege 7a nur relativ dünn ausgebildet sind, ergibt sich eine gleichmäßige, flächige Benetzung der Deckschicht 3.The elastic mat 2 has recesses 7 on the upper side, which are separated from each other by webs 7a. The recesses 7 have a square shape, with any other shape is suitable without affecting the technical effect of the recesses 7. The recesses 7 occupy a substantially larger area of the covering element 1 with respect to the webs 7 a, so that the elastic mat 2-viewed from above-consists almost exclusively of recesses 7. Fill these wells 7 with water, for example by sprinkling the covering element 1 from above, so this remains in the wells 7 are relatively long and thus moistens the top layer 3. Since the webs 7a are formed only relatively thin, results in a uniform, flat Wetting of the cover layer 3.

Die Figur 3 zeigt das Belagselement 1 gemäß Figur 2 von unten. Aus dieser Darstellung ist zu entnehmen, daß die Unterseite der elastischen Matte 2 eine Strukturierung 8, 9 aufweist. Insbesondere weist die elastische Matte unterseitig eine Anzahl von über die Fläche gleichmäßig verteilter Noppen 8 auf, die durch Stege 9 miteinander verbunden sind. Die Noppen 8 bewirken dabei eine bessere Verbindung der elastischen Matte 2 mit einem Untergrund. Die Stege 9 sind dünner als die Noppen 8 ausgebildet und dienen hauptsächlich der Stabilisierung der Noppen 8. Zusätzlich können die Stege 9 auch eine Verbesserung des Haltes des Belagselements 1 gegen Seitenkräfte bewirken.FIG. 3 shows the covering element 1 according to FIG. 2 from below. From this illustration it can be seen that the bottom of the elastic mat 2 has a structuring 8, 9. In particular, the elastic mat has underside a number of evenly distributed over the surface nubs 8, which are interconnected by webs 9. The knobs 8 cause a better connection of the elastic mat 2 with a substrate. The webs 9 are formed thinner than the knobs 8 and serve mainly to stabilize the knobs 8. In addition, the webs 9 can also improve the holding of the covering element 1 against lateral forces.

Figur 4 zeigt eine Schnittdarstellung durch eine Vorrichtung 10 zur Herstellung des Belagselements 1 gemäß Figur 1. Die Vorrichtung 10 weist eine wannenartige Form 10 auf, deren Innenkontur 12 die Form des Belagselements 1 ergibt. In die Form 11 ist eine Pufferschicht 13 in Form von feinem Sand eingefüllt. Diese Pufferschicht 13 soll verhindern, daß beim späteren Preßvorgang das Kunstharz über die Deckschicht 3 hinweggedrückt wird. Auf die Pufferschicht 13 sind die Steine 6 aufgeschüttet, die die spätere Deckschicht 3 ergeben sollen. Die Steine 3 drükken sich dabei teilweise in die Pufferschicht 13 ein. Auf diese Steinschüttung wird ein Gemisch von Gummigranulat 4 und Kunstharz 5 gefüllt, aus dem sich beim späteren Preßvorgang die elastische Matte 2 bildet. Die unterschiedlichen Siebfraktionen des Gummigranulats 4 sind in der vergrößerten Darstellung gemäß Figur 2 leicht zu erkennen. Die kleinere Siebfraktion wird von einem Gummimehl gebildet.FIG. 4 shows a sectional view through a device 10 for producing the covering element 1 according to FIG. 1. The device 10 has a trough-like shape 10, the inner contour 12 of which gives the shape of the covering element 1. In the mold 11, a buffer layer 13 is filled in the form of fine sand. This buffer layer 13 is intended to prevent the synthetic resin from being pressed over the cover layer 3 during the subsequent pressing process. On the buffer layer 13, the stones 6 are heaped up, which should give the subsequent cover layer 3. The stones 3 thereby partially press into the buffer layer 13. On this riprap a mixture of rubber granules 4 and 5 resin is filled, from which forms the elastic mat 2 during the subsequent pressing process. The different sieve fractions of the rubber granules 4 can be easily recognized in the enlarged view according to FIG. The smaller sieve fraction is formed by a rubber powder.

Nach dem Füllen der Form 11 in der vorbeschriebenen Weise drückt ein Preßstempel 14 mit vordefiniertem Druck in die Form 11, um die vorbeschriebenen Schüttungen zusammen zu pressen. Gleichzeitig werden die Form 11 und der Preßstempel 14 erwärmt, um eine möglichst rasche Aushärtung des Kunstharzes 5 zu erzielen.After filling the mold 11 in the manner described above presses a ram 14 with predefined pressure in the mold 11 to the above-described beds together press. At the same time the mold 11 and the ram 14 are heated to achieve the fastest possible curing of the resin 5.

Nach vollständiger Aushärtung des Kunstharzes 5 wird der Preßstempel 14 zurückgezogen, so daß das fertige Belagselement 1 aus der Form 11 entnommen werden kann.After complete curing of the synthetic resin 5 of the ram 14 is withdrawn, so that the finished covering element 1 can be removed from the mold 11.
