Description

Die vorliegende Erfindung betrifft einen Bodenaufbau, insbesondere Sportboden, mit einer Vielzahl von Paneelen, die durch ein Extrusionsverfahren hergestellt sind und aus einer Mischung aus Naturfasern und einem Polymerwerkstoff bestehen, wobei die Paneele an einer Unterkonstruktion festgelegt sind, die auf einem Boden verlegbar ist.
Die EP 1 524 385 offenbart einen Bodenbelag mit extrudierten Platten, die aus einer Mischung aus Naturfasern und einem Polymerwerkstoff bestehen. Die Platten weisen eine profilierte rutschhemmende Oberfläche auf und werden an einer Unterkonstruktion festgelegt, beispielsweise für Terrassen und andere begehbare Flächen im Außenbereich. Die dort gezeigte Konstruktion hat sich an sich bewährt, ist allerdings für die Verwendung als Sportboden nicht geeignet.The present invention relates to a floor structure, in particular sports floor, with a plurality of panels, which are produced by an extrusion process and consist of a mixture of natural fibers and a polymer material, wherein the panels are fixed to a substructure, which can be laid on a floor.
The EP 1 524 385 discloses a floor covering with extruded panels made of a blend of natural fibers and a polymeric material. The panels have a profiled anti-slip surface and are fixed to a substructure, for example, for terraces and other outdoor walkways. The construction shown there has proven itself, but is not suitable for use as a sports floor.

Die EP266929 A2 offenbart einen Bodenaufbau mit den Merkmalen des Oberbegriffs des Anspruchs 1. Zudem sind Sportböden aus Sporthallen bekannt, bei denen ein flächenelastischer Sportboden federnd an einer Unterkonstruktion gelagert ist. Der Sportboden umfasst verleimte und beschichtete Hölzer, die eine ebene Oberfläche ausbilden, die für diverse Ballsportarten genutzt werden kann. Ein Einsatz dieser Sportböden aus Holzwerkstoffen im Freien ist jedoch nicht möglich, da die verwendeten Materialien nicht witterungsbeständig sind. Zudem ist der Pflegeaufwand hoch und die Nutzungsdauer gering.
Es ist daher Aufgabe der vorliegenden Erfindung einen Bodenaufbau, insbesondere einen Sportboden, zu schaffen, der auch außerhalb von Hallen einsetzbar und leicht zu verlegen ist.
Diese Aufgabe wird mit einem Bodenaufbau mit den Merkmalen des Anspruches 1 gelöst.
Erfindungsgemäß sind die extrudierten Paneele aus einer Mischung aus Naturfasern und einem Polymerwerkstoff über die Unterkonstruktion federnd elastisch gelagert, sodass der Bodenaufbau auch als Sportboden verwendet werden kann. Die extrudierten Paneele sind dabei witterungsbeständig und können im Außenbereich verlegt werden. Dabei wird der Vorteil genutzt, dass die Paneele aufgrund des eingesetzten Materials aus einer Mischung aus einem Polymer und Naturfasern nicht wesentlich schwinden und die Fugen nach dem Aufbau nicht wesentlich größer werden.The EP266929 A2 discloses a floor structure with the features of the preamble of claim 1. In addition, sports floors from sports halls are known in which a surface elastic sports floor is resiliently mounted on a substructure. The sports floor comprises glued and coated woods, which form a flat surface that can be used for various ball sports. However, it is not possible to use these sports floors made of wood-based materials outdoors because the materials used are not weather-resistant. In addition, the maintenance effort is high and the useful life is low.
It is therefore an object of the present invention to provide a floor structure, in particular a sports floor, which can also be used outside of halls and easy to install.
This object is achieved with a floor structure with the features of claim 1.
According to the extruded panels of a mixture of natural fibers and a polymer material are resiliently mounted on the substructure, so that the floor structure can also be used as a sports floor. The extruded panels are weather-resistant and can be laid outdoors. The advantage is used that the panels due to the material used from a mixture of a Polymer and natural fibers do not shrink significantly and the joints after assembly are not significantly larger.

Vorzugsweise ist der Federweg der Paneele bei einer Belastung von 80 kg mindestens 2 mm, vorzugsweise mindestens 3 mm. Dadurch wird eine ausreichende Elastizität bereitgestellt, um den Bodenaufbau als Sportboden einsetzen zu können, beispielsweise für Ballsportarten, wie Handball, Basketball oder andere Sportarten, die ansonsten nur in Sporthallen stattfinden.Preferably, the travel of the panels at a load of 80 kg is at least 2 mm, preferably at least 3 mm. As a result, a sufficient elasticity is provided in order to use the floor structure as a sports floor, for example, for ball sports, such as handball, basketball or other sports that otherwise take place only in sports halls.

Die Paneele weist vorzugsweise eine ebene Oberfläche auf. Dabei ist der Abstand zwischen zwei Paneelen zumindest an den Längsseiten zwischen 1 und 4 mm, insbesondere 2 bis 3,5 mm groß. Dadurch wird gewährleistet, dass bei Regenfall das Wasser zwischen den Paneelen ablaufen kann und sich keine größeren Pfützen bilden. Der Spalt zwischen den Paneelen ist dabei vorzugsweise auf weniger als 3 mm eingestellt, da dann eine Verletzungsgefahr von eingeklemmten Fingern an den Spalten ausgeschlossen werden kann. Dabei wird der vorteilhafte Effekt genutzt, dass die extrudierten Paneele aus einer Mischung aus Naturfasern und einem Polymerwerkstoff sich nach dem Verlegen durch Aufnahme von Feuchtigkeit allenfalls geringfügig ausdehnen, aber ansonsten formstabil bleiben und nicht aufschüsseln, wie dies bei Holzwerkstoffen der Fall ist.The panels preferably have a flat surface. The distance between two panels is at least on the long sides between 1 and 4 mm, in particular 2 to 3.5 mm in size. This ensures that in the event of rain, the water can drain between the panels and no larger puddles form. The gap between the panels is preferably set to less than 3 mm, since then a risk of injury can be excluded by pinched fingers on the columns. In this case, the advantageous effect is used that the extruded panels of a mixture of natural fibers and a polymer material at most slightly expand after installation by absorbing moisture, but otherwise remain dimensionally stable and not aufschüsseln, as is the case with wood-based materials.

Jedes Paneel weist an den Längsseiten vorzugsweise eine Nut auf, an die mindestens eine Klammer zur Festlegung an die Unterkonstruktion eingefügt ist. Dadurch können die Paneele so verlegt werden, dass keine Befestigungsmittel an der Oberseite hervorstehen.Each panel preferably has a groove on the longitudinal sides, to which at least one clip is inserted for attachment to the substructure. This allows the panels to be laid so that no fasteners protrude from the top.

Für eine stabile Abstützung der Paneele umfasst die Unterkonstruktion Balken. Unter den Balken sind vorzugsweise Dämpfungspads zur Belastung der elastischen Lagerung der Paneele, sodass durch die Dämpfungspads unterhalb der Balken ein flächenelastischer Boden aus den Paneelen bereitgestellt wird. Die Dämpfungspads bestehen vorzugsweise aus einem elastischen Kunststoff, Gummi, Kautschuk oder einer Mischung dieser Materialien. Für die Einstellung der Dämpfungseigenschaften kann die Dicke der Dämpfungspads und/oder die Shore-Härte entsprechend eingestellt werden.For stable support of the panels, the substructure comprises beams. Under the bars are preferably damping pads for loading the elastic mounting of the panels, so that a surface-elastic bottom of the panels is provided by the damping pads below the beams. The damping pads are preferably made of a resilient plastic, rubber, rubber or a mixture of these materials. For adjusting the damping properties, the thickness of the damping pads and / or the Shore hardness can be adjusted accordingly.

Ferner umfasst die Unterkonstruktion vorzugsweise Platten, auf denen die Dämpfungspads aufliegen. Die Platten können dabei aus Stein oder Beton hergestellt sein und ein hohes Eigengewicht aufweisen. Dadurch wird verhindert, dass der Bodenaufbau sich während der Benutzung verschiebt oder absenkt.Furthermore, the substructure preferably comprises plates on which the damping pads rest. The plates can be made of stone or concrete be and have a high dead weight. This prevents the floor structure from shifting or lowering during use.

Vorzugsweise sind die Balken des Bodenaufbaus über mindestens eine Schraube an einer Platte gegen ein Abheben gesichert. Über die Schrauben sind die Balken an den Platten festgelegt, während die Paneele über entsprechende Klammern an den Balken fixiert sind, sodass der Bodenaufbau nach der Montage eine zusammenhängende Einheit ausbildet.Preferably, the beams of the floor structure are secured by at least one screw on a plate against lifting. The screws are used to fix the beams to the panels, while the panels are fixed to the beams by means of appropriate clamps so that the floor structure forms a coherent unit after installation.

Um ein Verschieben der Paneele in horizontaler Richtung zu vermeiden, ist auf den Balken vorzugsweise ein elastisches Element, insbesondere ein Streifen angeordnet, auf dem ein Paneel mit einer Unterseite aufliegt. Als elastische Elemente kommen Streifen aus Gummi, elastischen Kunststoffmaterialien oder anderen Materialien zum Einsatz, die an der Oberseite der Balken eingebettet oder fixiert sind und ein Verrutschen der Paneele in horizontaler Richtung vermeiden.In order to avoid a displacement of the panels in the horizontal direction, an elastic element, in particular a strip is arranged on the beam, preferably, on which a panel rests with a bottom. As elastic elements are strips of rubber, elastic plastic materials or other materials are used, which are embedded or fixed to the top of the beams and prevent slipping of the panels in the horizontal direction.

Die Paneele sind vorzugsweise witterungsbeständig ausgebildet und besitzen einen Anteil an Naturfasern über 50 Prozent, vorzugsweise über 65 Prozent. An Naturfasern können insbesondere Holzfasern, Holzspäne, Stroh, Heu, Reisschalen oder andere faserhaltigen Naturprodukte eingesetzt werden. Die Materialmischung ist dabei so gewählt, dass auch unter Feuchtigkeit keine nennenswerte Ausdehnung oder ein Schwinden der Paneele erfolgt und die Fugen im Wesentlichen konstant bleiben.The panels are preferably weather-resistant and have a proportion of natural fibers over 50 percent, preferably over 65 percent. In particular, wood fibers, wood chips, straw, hay, rice husks or other fibrous natural products can be used on natural fibers. The material mixture is chosen so that even under moisture no appreciable expansion or shrinkage of the panels and the joints remain substantially constant.

Ein Bodenaufbau 1 umfasst eine Vielzahl von Paneelen 2, die in einem Extrusionsverfahren hergestellt sind und aus einer Mischung aus Naturfasern und einem Polymerwerkstoff bestehen. Die Naturfasern können Holzfasern, Holzspäne, Stroh, Heu, Reisschalen oder andere Naturfasern umfassen, während der Polymerwerkstoff aus Polypropylen, Polyethylen oder anderen Polymeren bestehen kann. Zudem können die Paneele auch einen Anteil an Zement oder anderen Zusatzstoffen enthalten. Die Materialmischung ist dabei so gewählt, dass unter Witterungseinflüssen keine wesentliche Formveränderung der Paneele 2 erfolgt. Zur Erhöhung der Rauhigkeit kann die Oberfläche der Paneele 2 gebürstet sein.A floor structure 1 comprises a plurality of panels 2 made by an extrusion process and a mixture of natural fibers and a polymer material. The natural fibers may include wood fibers, wood chips, straw, hay, rice husks or other natural fibers, while the polymeric material may be polypropylene, polyethylene or other polymers. In addition, the panels may also contain a proportion of cement or other additives. The material mixture is chosen so that no significant change in shape of the panels 2 takes place under the influence of weather. To increase the roughness, the surface of the panels 2 may be brushed.

Die Paneele 2 bilden eine ebene Oberfläche aus und sind in einem Abstand zueinander verlegt. An den Längsseiten der Paneele 2 ist ein Spalt 3 ausgebildet, der eine Breite zwischen 1 und 4 mm, vorzugsweise 2 bis 3,5 mm besitzt. An den Stirnseiten ist ebenfalls ein Spalt 4 ausgebildet, der die gleiche Breite besitzen kann wie der Spalt 3.The panels 2 form a flat surface and are spaced apart. On the longitudinal sides of the panels 2, a gap 3 is formed, which has a width between 1 and 4 mm, preferably 2 to 3.5 mm. At the end faces also a gap 4 is formed, which may have the same width as the gap. 3

Die Paneele 2 sind an einer Unterkonstruktion federnd elastisch gelagert, wie dies in Figur 2 gezeigt ist. Die Unterkonstruktion umfasst eine Vielzahl von Balken 7, die im Wesentlichen parallel zueinander ausgerichtet sind und auf welchen die Paneele 2 aufliegen. Die Balken 7 bestehen aus extrudierten Profilen aus einer Mischung aus Naturfasern und einem Polymerwerkstoff und können aus dem gleichen Material hergestellt sein, wie die Paneele 2. Die Balken 7 sind als Hohlprofile ausgebildet und sorgen dafür, dass die Paneele 2 in einem Abstand zu einem Boden 10 angeordnet sind. Die Balken 7 liegen dabei auf Dämpfungspads 8 auf, die für eine elastische Lagerung der Paneele 2 sorgen. Die Dämpfungspads 8 können aus einem elastischen Kunststoff, Gummi, Kautschuk oder einer Mischung dieser Materialien hergestellt sein, wobei die Dämpfungspads eine Dicke von 1 cm bis 5 cm, insbesondere 1,5 cm bis 4 cm aufweisen. Zur Einstellung der Elastizität der Paneele 2 kann die Shore-Härte entsprechend eingestellt werden.The panels 2 are resiliently mounted on a substructure, as in FIG. 2 is shown. The substructure comprises a plurality of beams 7, which are aligned substantially parallel to each other and on which the panels 2 rest. The beams 7 are made of extruded profiles of a mixture of natural fibers and a polymer material and may be made of the same material as the panels 2. The beams 7 are formed as hollow profiles and ensure that the panels 2 at a distance from a floor 10 are arranged. The bars 7 rest on damping pads 8, which provide elastic support of the panels 2. The damping pads 8 may be made of a resilient plastic, rubber, rubber or a mixture of these materials, wherein the damping pads have a thickness of 1 cm to 5 cm, in particular 1.5 cm to 4 cm. To adjust the elasticity of the panels 2, the Shore hardness can be adjusted accordingly.

Die Dämpfungspads 8 liegen auf Platten 9 aus Stein oder Beton auf, sodass gewährleistet ist, dass der Bodenaufbau ein ausreichendes Gewicht besitzt und nicht verrutschen kann. Die Platten 9 sind auf einem Boden 10 abgestützt, der beispielsweise aus einem Kiesbett besteht.The damping pads 8 rest on plates 9 made of stone or concrete, so that it is ensured that the floor structure has a sufficient weight and can not slip. The plates 9 are supported on a floor 10, which consists for example of a gravel bed.

Die Unterkonstruktion aus den Balken 7, den Dämpfungspads 8 und den Platten 9 ist über Schrauben 11 zusammengehalten, die die Balken 7 und die Dämpfungspads 8 durchgreifen und in den Platten 9 fixiert sind. Über die Schrauben 11 wird verhindert, dass die Balken 7 nach oben abgehoben werden. Eine Bewegung der Balken 7 aufgrund der federnden Lagerung durch die Dämpfungspads 8 ist hingegen möglich.The substructure of the beams 7, the damping pads 8 and the plates 9 is held together by screws 11 which pass through the beams 7 and the damping pads 8 and are fixed in the plates 9. About the screws 11 prevents the beams 7 are lifted upwards. A movement of the beams 7 due to the resilient mounting by the damping pads 8, however, is possible.

Auf den Balken 7 sind ferner elastische Elemente, vorzugsweise Streifen 12 aus einem Gummimaterial festgelegt, die an der Oberseite der Balken 7 verklebt oder mit einextrudiert sind. Die Paneele 2 liegen mit einer Unterseite auf den elastischen Elementen 12 auf und sind somit gegen ein Verrutschen in horizontaler Richtung gesichert.Elastic elements, preferably strips 12 of a rubber material, which are glued or extruded on the upper side of the beams 7, are also fastened to the beams 7. The panels 2 rest with an underside on the elastic elements 12 and are thus secured against slipping in the horizontal direction.

Die Paneele 2 weisen ferner an ihren Längsseiten Nuten 5 auf, in die Klammern 6 mit hervorstehenden Armen eingefügt sind. Die Klammern 6 sind mit den Balken 7 verschraubt, sodass keine Befestigungsmittel an der Oberseite der Paneele 2 hervorstehen. Dabei können über die Länge der Paneele 2 verteilt mehrere Klammern 6 zur Fixierung vorgesehen sein. Die Paneele 2 können eine Länge zwischen 15 cm und 3 m aufweisen, vorzugsweise 1 m bis 2 m. Die Breite der Paneele 2 liegt in einem Bereich zwischen 10 cm und 40 cm, insbesondere 15 cm bis 25 cm.The panels 2 also have on their longitudinal sides grooves 5, are inserted into the brackets 6 with protruding arms. The brackets 6 are bolted to the beams 7, so that no fastening means on the top of the panels 2 protrude. In this case, distributed over the length of the panels 2 several brackets 6 may be provided for fixing. The panels 2 may have a length between 15 cm and 3 m, preferably 1 m to 2 m. The width of the panels 2 is in a range between 10 cm and 40 cm, in particular 15 cm to 25 cm.

In Figur 4 ist die Unterkonstruktion mit den Balken 7 und den darauf angeordneten streifenförmigen elastischen Elementen 12 gezeigt. Die Balken 7 liegen auf den senkrecht zu den Balken 7 ausgerichteten Platten 9 auf, die wiederum auf dem Kiesbett 10 aufliegen. Auf dieser Unterkonstruktion können nun die Paneele 2 aufgelegt werden und über die Klammern 6 an den Balken 7 fixiert werden.In FIG. 4 the substructure with the beams 7 and the strip-shaped elastic elements 12 arranged thereon is shown. The bars 7 rest on the perpendicular to the bars 7 aligned plates 9, which in turn rest on the gravel bed 10. The panels 2 can now be placed on this substructure and fixed to the beams 7 via the clamps 6.

In dem dargestellten Ausführungsbeispiel wird die Flächenelastizität des Bodenaufbaus über die Dämpfungspads 8 erhalten, die unter den Balken 7 angeordnet sind. Es ist natürlich auch möglich, mehrere elastische Elemente in der Unterkonstruktion vorzusehen, die zusammen eine flächenelastische Lagerung der Paneele 2 ermöglichen.In the illustrated embodiment, the surface elasticity of the floor structure is obtained via the damping pads 8, which are arranged under the beams 7. Of course, it is also possible to provide a plurality of elastic elements in the substructure, which together allow a surface elastic mounting of the panels 2.

Der gezeigte Bodenaufbau eignet sich insbesondere zur Verlegung im Freien als Sportboden, beispielsweise für Basketballplätze, Handballplätze oder andere Sportarten.The floor construction shown is particularly suitable for outdoor installation as a sports floor, for example, for basketball courts, handball courts or other sports.
