Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer fugenlosen und porösen Granulatdecke nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for producing a jointless and porous granulated blanket according to the preamble of claim 1.

Ein Verfahren dieser Art ist aus der BE 824 809 A bekannt geworden. Das hier offenbarte Granulat weist eine Grösse von 2 und 18 mm und bei einer Dicke der Granulatdecke von 1 bis 3 cm eine Grösse von 4 bis 7 mm auf. Das Granulat ergibt je nach seiner Grösse an der Oberseite des Belages eine Struktur, welche die Rutschfestigkeit des Belages gewährleisten soll.A method of this kind has become known from BE 824 809 A. The granules disclosed herein have a size of 2 and 18 mm and, with a granule cover thickness of 1 to 3 cm, a size of 4 to 7 mm. The granules, depending on their size at the top of the coating, a structure which is to ensure the skid resistance of the coating.

Granulatdecken haben sich als elastische Beläge sowohl für den Breiten- als auch für den Spitzensport an sich bewährt und eine weite Verbreitung gefunden. An diese werden die Anforderung gestellt, dass sie allwetterfest, verschleissfest und als Laufbelag spikefest sind. Poröse Granulatdecken haben den Vorteil, dass sie schneller abtrocknen, als undurchlässige Beläge, die durch gegossene Schichten oder das Verlegen von vulkanisierten Gummimatten hergestellt werden. Bei solchen wasserundurchlässigen Belägen besteht die Gefahr, dass sich durch Dampfdruck Blasen bilden können und der Belag erneuert oder repariert werden muss.Granule ceilings have proven themselves as elastic coverings for both the general and elite sports and have found wide use. These are the requirement that they are all weatherproof, wear resistant and spike resistant tread. Porous granular coverings have the advantage that they dry faster than impermeable coverings produced by cast layers or the laying of vulcanized rubber mats. In the case of such water-impermeable coverings, there is the risk that bubbles may form due to vapor pressure and the covering must be renewed or repaired.

Ein Sportbelag für eine Laufbahn muss an der Oberseite strukturiert sein. Gleichzeitig soll ein solcher Belag verschleissfest und insbesondere spikefest sein. Nach anderen bekannten Verfahren wird auf einem ebenen Untergrund aus Granulat und Bindemittel eine elastische Schicht gebildet. Das Granulat kann für diese elastische Schicht aus schwarzen oder farbigen Granulaten hergestellt werden. Auf diese Schicht wird eine Verschleissschicht aufgespritzt oder gegossen und in die flüssige Schicht Granulat eingestreut. Das an der Oberseite vorstehende Granulat bildet eine strukturierte Oberfläche. Ein schematischer Schnitt durch eine solche Granulatdecke ist in Fig. 6 dargestellt. Das oberflächig vorstehende Granulat ist noch teilweise eingebunden und kann sich bei einer Benutzung lösen. Bei einer Granulatdecke mit gespritzter Verschleissschicht besteht somit die Schwierigkeit, dass die Abnützung vergleichsweise gross ist. Das oberflächige Granulat könnte durch Aufbringen eines Bindemittels verfestigt werden. Dies führt jedoch zu einer vergleichsweise harten Oberfläche und einer verringerten Wasserdurchlässigkeit.A sports surface for a career must be structured at the top. At the same time, such a covering should be wear-resistant and, in particular, resistant to spikes. According to other known methods, an elastic layer is formed on a flat substrate of granules and binder. The granules can be prepared for this elastic layer of black or colored granules. On this layer, a wear layer is sprayed or poured and sprinkled into the liquid layer of granules. The granules projecting at the top form a structured surface. A schematic section through such a granulated cover is shown in FIG. The superficially protruding granules are still partially embedded and can become loose during use. In the case of a granulated cover with sprayed wear layer, there is therefore the difficulty that the wear is comparatively great. The surface granules could be solidified by applying a binder. However, this leads to a comparatively hard surface and a reduced water permeability.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung einer Granulatdecke eines Sportbelages zu schaffen, mit dem eine verschleissfestere und insbesondere spikefestere Granulatdecke hergestellt werden kann, welche gleichzeitig eine strukturierte Oberfläche aufweist. Das Verfahren soll trotzdem einfach und kostengünstig durchführbar sein.The invention has for its object to provide a method for producing a granular cover of a sports covering, with which a more wear-resistant and spiked in particular granular cover can be produced, which at the same time has a textured surface. Nevertheless, the method should be simple and inexpensive to carry out.

Die Erfindung ist gemäss Anspruch 1 gelöst. Mit dem erfindungsgemässen Verfahren kann eine Granulatdecke hergestellt werden, bei welcher das oberseitige Granulat wesentlich fester eingebunden ist als beim Stand der Technik. Die Oberflächenstruktur wird hier nicht durch einzelne Granulatkörner gebildet, sondern durch Vertiefungen, die in die Oberseite der Granulatdecke eingearbeitet wurden. Das Granulat besitzt eine mittlere Korngrösse von 0,1 bis 3 mm, wodurch sich eine hohe Verschleissfestigkeit ergibt.The invention is solved according to claim 1. With the method according to the invention, a granulated cover can be produced, in which the top-side granules are much more firmly integrated than in the prior art. The surface structure is not formed here by individual granules, but by depressions, which were incorporated into the top of the granulated cover. The granules have a mean particle size of 0.1 to 3 mm, resulting in a high wear resistance.

Die FR 80 841 E offenbart zwar eine Walze, die am Umfang vorstehende Nocken aufweist, um in einem Belag als Gleitschutz entsprechende Vertiefungen einzuarbeiten, diese ist aber nur fĂĽr den Einsatz im StraĂźenbau beschrieben.Although FR 80 841 E discloses a roller which has circumferentially projecting cams to incorporate corresponding depressions in a lining as antiskid, but this is only described for use in road construction.

Eine besonders hohe Verschleissfestigkeit ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung das Granulat eine Korngrösse im Bereich von 0,5 bis 1,5 mm aufweist. Die durchschnittliche Korngrösse ist hier wesentlich kleiner als bei den bekannten Granulatdecken. Das Granulat ist oberseitig besonders fest eingebettet und kann bei einer Belastung, beispielsweise durch die Belastung im Laufsport nicht aus dem Verbund gelöst werden. Durch Wahl unterschiedlicher Prägeflächen können im Wesentlichen beliebige Strukturen hergestellt werden. Als besonders vorteilhaft hat sich eine Struktur herausgestellt, die ähnlich ausgebildet ist wie die Aussenseite eines Golfballes. Die Vertiefungen sind jedoch vorteilhafterweise unregelmässig angeordnet.A particularly high resistance to wear results when, according to a development of the invention, the granules have a particle size in the range of 0.5 to 1.5 mm. The average grain size is much smaller than in the known granule blankets. The granules are particularly firmly embedded on the upper side and can not stand up under load, for example due to the stress of running be solved in the composite. By choosing different stamping surfaces essentially any structures can be produced. To be particularly advantageous, a structure has been found that is similar to the outside of a golf ball. However, the depressions are advantageously arranged irregularly.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der verdichtete Belag mit einer Walze strukturiert wird. Die Walze besitzt eine unebene Walzenoberfläche, die komplementär zur Struktur der Granulatdecke ausgebildet ist. Eine solche Walze wird vorzugsweise von Hand geschoben. Durch wechselnde Richtung kann eine unregelmässig strukturierte Oberfläche geschaffen werden. Wesentlich ist, dass der Belag strukturiert wird, solange das Bindemittel noch nicht ausgehärtet ist. Bei einem Bindemittel aus einem Polyurethan stehen hier mehrere Stunden zur Verfügung.According to a development of the invention, it is provided that the compacted covering is structured with a roller. The roller has an uneven roller surface which is complementary to the structure of the granulated cover. Such a roller is preferably pushed by hand. By changing direction, an irregularly structured surface can be created. It is essential that the coating is structured as long as the binder is not cured. With a polyurethane binder there are several hours available.

Das erfindungsgemässe Verfahren ermöglicht die Herstellung einer einschichtigen oder mehrschichtigen Granulatdecke. Das Verfahren ermöglicht somit auch die Herstellung einer zweischichtigen Granulatdecke, bei welcher die untere Schicht aus einem schwarzen oder farbigen Gummigranulat auf der Basis von SBR oder EPDM-Granulat sowie einem Bindemittel besteht. Diese Schicht kann eine höhere Elastizität aufweisen als die obere Verschleissschicht und dient der Verbesserung des Kraftabbaus.The process according to the invention makes it possible to produce a single-layered or multi-layered granulated cover. The process thus also makes it possible to produce a two-layer granulated blanket in which the lower layer consists of a black or colored rubber granulate based on SBR or EPDM granules and a binder. This layer can have a higher elasticity than the upper wear layer and serves to improve the power reduction.

Zur Herstellung einer erfindungsgemässen Granulatdecke, beispielsweise für einen Sportplatz, wird ein ebener Untergrund 7 aus Asphalt hergestellt. Auf die ebene Oberseite 2 des Untergrundes 7 wird mit einem Trichter 8 ein Belag 6 aus einem Granulat 3 und einem Bindemittel 5 aufgebracht. Das Granulat 3 und das Bindemittel 5 werden gemischt in die Einbaumaschine gegeben oder von Hand geschüttet und als Gemisch 9 aufgetragen.To produce a granulated cover according to the invention, for example for a sports field, a flat base 7 is produced from asphalt. On the flat upper side 2 of the substrate 7, a covering 6 made of a granulate 3 and a binder 5 is applied with a funnel 8. The granules 3 and the binder 5 are mixed in the built-in machine or poured by hand and applied as a mixture 9.

Das Granulat 3 ist insbesondere SBR oder EPDM-Granulat mit einer mittleren Korngrösse im Bereich von 0,1 bis 3 mm. Vorzugsweise beträgt die mittlere Korngrösse 0,5 bis 1,5 mm. Das Bindemittel 5 ist ein an sich bekanntes Polyurethan und besitzt eine Aushärtzeit von mehreren Stunden. Der Belag 6 wird in Bahnen aufgetragen, welche vor dem Aushärten des Binders 5 fugenlos miteinander verbunden werden.The granulate 3 is in particular SBR or EPDM granules having an average particle size in the range of 0.1 to 3 mm. Preferably, the mean grain size is 0.5 to 1.5 mm. The binder 5 is a per se known polyurethane and has a curing time of several hours. The coating 6 is applied in webs, which are joined together without joints before curing of the binder 5.

Nach dem Aufbringen des Belages 6 wird dieser gemäss Fig. 2 oberseitig mit einem geheizten Balken 12 geglättet. Der Balken 12 ist ebenfalls an einem hier nicht gezeigten Fahrzeug befestigt und wird in Fig. 2 in Richtung des Pfeiles 13 bewegt. Durch den Balken 12 wird ein verdichteter Belag 15 mit einen ebenen Oberfläche 14 hergestellt. Die unebene Oberfläche 11 des Belages 6 wird somit geglättet, und gleichzeitig wird der Belag 6 verfestigt. Die Dicke des Belages 15 ist überall gleich und beträgt beispielsweise 0,1 bis 3 cm.After application of the coating 6 of this is smoothed on the upper side with a heated beam 12 as shown in FIG. The beam 12 is also attached to a vehicle, not shown here, and is moved in Fig. 2 in the direction of arrow 13. By the beam 12, a compacted coating 15 with a flat surface 14 is produced. The uneven surface 11 of the pad 6 is thus smoothed, and at the same time the pad 6 is solidified. The thickness of the pad 15 is the same everywhere and is for example 0.1 to 3 cm.

Über den verfestigten Belag 15 wird gemäss Fig. 3 eine Walze 16 gestossen, die eine strukturierte Walzenfläche 19 aufweist. In der Fig. 3 dreht die Walze 16 im Uhrzeigersinn um eine Achse 17 und wird in Richtung des Pfeiles 18 von links nach rechts bewegt. Die glatte Oberseite 14 des verdichteten Belages 15 wird durch Fläche 19 geprägt und mit einer strukturierten Oberseite 20 versehen. Die Walze 16 kann mehrmals mit unterschiedlicher oder gleichbleibender Richtung über den verdichteten Belag 15 gefahren werden. Die Oberflächenstruktur wird dann unregelmässig mit Vertiefungen 4, wie die Fig. 4 und 5 zeigen. Die Walze 16 wird über den verdichteten Belag 15 gefahren, solange dieser Belag 15 noch nicht ausgehärtet ist. Nach dem Aufbringen des Belages 6 gemäss Fig. 1 stehen hierzu einige Stunden zur Verfügung. Die Walze 16 kann beheizt sein, um ein Festkleben von Granulat an der Oberfläche 19 zu verhindern. Durch die Walze 16 wird das oberseitige Granulat in den Belag 15 gedrückt und damit eingebettet. Dadurch wird die erwähnte Verschleissfestigkeit verbessert. Die unterschiedliche Einbettung des Granulates an der Oberseite zeigt ein Vergleich der Fig. 5 und 6. Die in Fig. 6 gezeigte Granulatdecke 30 nach dem Stand der Technik weist eine untere elastische Schicht a' und eine Verschleissschicht b' auf. Das Granulat 32 der elastischen Schicht a' ist aus einem Gummigranulat hergestellt. Die Verschleissschicht b' besteht aus einem gespritzten Granulat 31, das eine Oberseite 33 bildet, an welcher einzelne Granulatkörner 31 spitz vorstehen. Bei der Granulatdecke 1 gemäss Fig. 5 besteht die Verschleissschicht b aus einem vergleichsweise feinkörnigen Granulat 3 und weist eine Oberseite 20 auf, die durch Vertiefungen 5 strukturiert ist. Die Vertiefungen 4 wurden wie oben erläutert, durch Prägen mit der Walze 16 hergestellt. Das oberseitige Granulat 3a ist durch diese Walzen verfestigt worden und bildet sehr verschleissfeste Oberfläche.As shown in FIG. 3, a roller 16 which has a structured roller surface 19 is pushed over the solidified coating 15. In Fig. 3, the roller 16 rotates clockwise about an axis 17 and is moved in the direction of the arrow 18 from left to right. The smooth upper side 14 of the compacted covering 15 is embossed by surface 19 and provided with a structured upper side 20. The roller 16 can be driven several times with different or constant direction over the compacted coating 15. The surface structure will then irregularly with depressions 4, as Figs. 4 and 5 show. The roller 16 is moved over the compacted coating 15, as long as this coating 15 is not cured. After application of the covering 6 according to FIG. 1, a few hours are available for this purpose. The roller 16 may be heated to prevent sticking of granules to the surface 19. By the roller 16, the upper-side granules are pressed into the pad 15 and thus embedded. As a result, the aforementioned wear resistance is improved. The different embedding of the granules on the upper side shows a comparison of FIGS. 5 and 6. The prior art granulated cover 30 shown in FIG. 6 has a lower elastic layer a 'and a wear layer b'. The granules 32 of the elastic layer a 'is made of a rubber granules. The wear layer b 'consists of a sprayed granules 31, which forms an upper side 33, on which individual granules 31 protrude pointedly. In the case of the granulated cover 1 according to FIG. 5, the wear layer b consists of a comparatively fine-grained granulate 3 and has an upper side 20, which is structured by depressions 5. The recesses 4 were prepared by embossing with the roller 16 as explained above. The top-side granules 3a has been solidified by these rollers and forms a very wear-resistant surface.

Die Fig. 4 zeigt einen Ausschnitt aus der Granulatdecke 1, wobei ersichtlich ist, dass die Vertiefungen 4 unregelmässig oder regelmässig über die Oberseite 20 verteilt sind.FIG. 4 shows a detail of the granulated cover 1, wherein it can be seen that the depressions 4 are distributed irregularly or regularly over the upper side 20.

Durch die Verwendung einer Walze 16 mit einer ebenen Walzenfläche kann eine Granulatdecke 1 wenigstens bereichsweise so hergestellt werden, dass die Oberseite 20 glatt ist. Die gleiche Granulatdecke 1 kann somit bereichsweise strukturiert und bereichsweise glatt sein. Auf der gleichen Granulatdecke 1 kann somit ein strukturierter Bereich für den Laufsport und gleichzeitig ein Bereich mit einer ebenen Oberfläche beispielsweise für einen Ballsport hergestellt werden. Es können ebenfalls Bereiche mit unterschiedlicher Strukturierung hergestellt werden. Die Granulatdecke 1 ist sowohl bezüglich der Schicht a als auch der Schicht b porös. Wasser kann somit von der Oberseite 20 nach unten abfliessen.By using a roller 16 with a flat roller surface, a granulated cover 1 can be produced, at least in regions, so that the upper side 20 is smooth. The same granular cover 1 can thus be structured in regions and partially smooth. Thus, on the same granulated cover 1, a structured area for running and at the same time an area with a flat surface can be produced, for example for a ball sport. It is also possible to produce areas with different structuring. The granulated cover 1 is porous both with respect to the layer a and the layer b. Water can thus flow down from the top 20.
