Abstract

Rubber elastic granules (3) and a binder (5) are mixed and applied to a base (7) to form a sheetlike surfacing (6). The sheetlike surfacing is compacted and smoothed on its upper side (11) prior to curing of binder. The compacted surfacing is provided with a texture on its upper side by being subjected to mechanical pressure using an uneven embossing face. An Independent claim is also included for a granular covering.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer fugenlosen und porösen Granulatdecke, wobei gummielastisches Granulat und ein Bindemittel gemischt und zu einem flächigen Belag auf einen Untergrund aufgebracht werden. 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.The invention relates to a method for producing a seamless and porous granulate cover, with rubber-elastic granules and a binder mixed and to a flat covering be applied to a surface. Have granule ceilings themselves as elastic coverings for both width and top-class sport has proven itself and has been widely used. They are required to be all-weather resistant, are wear-resistant and spike-resistant as a tread. Porous granulate ceilings have the advantage that they dry faster, as impermeable coverings through cast layers or the laying of vulcanized rubber mats become. With such impermeable coverings, there is There is a risk that bubbles can form due to vapor pressure and that Rubber needs to be replaced or repaired.

Ein Sportbelag für eine Laufbahn muss an der Oberseite strukturiert sein. Gleichzeitig soll ein solcher Belag verschleissfest und insbesondere spikefest sein. Nach 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 needs to be textured on the top his. At the same time, such a covering should be wear-resistant and in particular be spike resistant. According to known methods on a flat surface made of granulate and binder elastic layer formed. The granules can be elastic for this Layer made of black or colored granules become. A wear layer is sprayed onto this layer or poured and sprinkled into the liquid layer of granules. The granules protruding from the top form one structured surface. A schematic section through a such a granulate cover is shown in Fig. 6. The superficial the above granulate is still partially integrated and can come loose during use. In the case of a granulate ceiling with sprayed Wear layer there is therefore the difficulty that the wear is comparatively large. The superficial Granules could be solidified by applying a binder become. However, this leads to a comparatively hard surface and reduced water permeability.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der genannten Art zu schaffen, mit dem eine verschleissfestere und insbesondere spikefestere Granulatdecke hergestellt werden kann. Das Verfahren soll trotzdem einfach und kostengünstig durchführbar sein.The invention has for its object a method of the above Way to create a more wear resistant and in particular, spike-resistant granulate cover can be produced. The method should nevertheless be simple and inexpensive to carry out his.

Die Erfindung ist dadurch gelöst, dass der flächige Belag vor dem Aushärten des Bindemittels verdichtet und an seiner Oberseite geglättet wird und dass der verdichtete Belag vor dem Aushärten des Bindemittels an seiner Oberseite mechanisch unter Druck mit einer unebenen Prägefläche mit einer Struktur versehen wird. 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.The invention is achieved in that the flat covering in front the hardening of the binder and compacted on its top is smoothed and that the compacted covering before curing the top of the binder mechanically under pressure is provided with a structure with an uneven embossing surface. With the method according to the invention, a granulate cover can be are produced in which the top-side granules are essential is more firmly integrated than in the prior art. The The surface structure is not created by individual granules formed but by depressions that are in the top the granulate ceiling were incorporated.

Eine besonders hohe Verschleissfestigkeit ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung das Granulat eine Korngrösse im Bereich 0,1 bis 3 mm, vorzugsweise 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 wear resistance results when According to a development of the invention, the granules have a grain size in the range 0.1 to 3 mm, preferably 0.5 to 1.5 mm. The average grain size is essential here smaller than with the known granulate blankets. The granules are particularly firmly embedded on the top and can for example due to the strain in running the network can be solved. By choosing different stamping surfaces can essentially produce any structure become. A structure has proven to be particularly advantageous which is similar to the outside of one Golf ball. However, the depressions are advantageously irregular arranged.

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 that is complementary to Structure of the granulate ceiling is formed. Such a roller is preferably pushed by hand. By changing direction an irregularly structured surface can be created. It is essential that the covering is structured as long as the binder has not yet hardened. With a binder made of a polyurethane are available for several hours.

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 method according to the invention enables the production of a single-layer or multi-layer granulate ceiling. The procedure thus also enables the production of a two-layer granulate cover, where the bottom layer is made of black or colored rubber granules based on SBR or EPDM granules as well as a binder. This layer can be one have higher elasticity than the upper wear layer and serves to improve the loss of power.

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.For the production of a granulate cover according to the invention, for example for a sports field, a level surface 7 made from asphalt. On the flat top 2 of the surface 7 with a funnel 8 is a coating 6 from a granulate 3 and a binder 5 applied. The granules 3 and the binder 5 are mixed into 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 granulate with a average grain size in the range of 0.1 to 3 mm. Preferably the average grain size is 0.5 to 1.5 mm. The binder 5 is a polyurethane known per se and has a curing time of several hours. The covering 6 is applied in strips, which seamlessly together before the binder 5 hardens get connected.

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 the covering 6 has been applied, it becomes as shown in FIG. 2 smoothed on the top with a heated bar 12. The bar 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 is a compacted covering 15 with a flat Surface 14 made. The uneven surface 11 of the covering 6 is thus smoothed, and at the same time the covering 6 is solidified. The thickness of the covering 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.According to FIG. 3, a roller 16 is placed over the solidified covering 15 encountered, which has a structured roller surface 19. In 3 rotates the roller 16 clockwise about an axis 17 and is moved in the direction of arrow 18 from left to right. The smooth top 14 of the compressed covering 15 is characterized by surface 19 and with a structured top 20 provided. The roller 16 can be used several times with different or constant direction over the compacted covering 15 be driven. The surface structure then becomes irregular with depressions 4, as shown in FIGS. 4 and 5. The roller 16 is driven over the compacted surface 15 as long as this surface 15 has not yet hardened. After applying the covering 6 according to FIG. 1 are available for a few hours. The roller 16 may be heated to prevent granules from sticking to prevent on the surface 19. Through the roller 16 that Granules on the upper side pressed into the covering 15 and thus embedded. This improves the wear resistance mentioned. The different embedding of the granules on the Top side shows a comparison of FIGS. 5 and 6. The one in FIG. 6 shown granulate cover 30 according to the prior art has a lower elastic layer a 'and a wear layer b'. The granules 32 of the elastic layer a 'are made of rubber granules manufactured. The wear layer b 'consists of a sprayed granules 31, which forms a top 33 which individual granules 31 protrude pointedly. With the granulate ceiling 1, the wear layer b consists of a comparatively fine-grained granulate 3 and has one Top 20, which is structured by depressions 5. The Wells 4 were as explained above, by embossing with the Roll 16 made. The top granulate 3a is through this Rolls have been solidified and forms 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 section of the granulate cover 1, wherein it can be seen that the depressions 4 are irregular or regular are distributed over the top 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 granulate cover 1 can be produced at least in certain areas be that the top 20 is smooth. The same granulate cover 1 can thus be structured in areas and in areas be smooth. So on the same granule cover 1 a structured area for running and at the same time an area with a flat surface, for example for one Ball sports are made. Areas can also be created with different structuring can be produced. The granulate ceiling 1 is both with respect to layer a and Layer b is porous. Water can thus go down from the top 20 flow away.
