Description

Die Erfindung bezieht sich auf einen Betonformstein zur Begrenzung eines mit einem Kunstrasen versehenen Spielfeldes, mit einem sich über die gesamte Steinlänge erstreckenden Schlitz zur Festlegung eines Randstreifens des Kunstrasens durch in den Schlitz eingeführte Verankerungselemente, wobei der Schlitz mit einem Wasserablauf verbunden ist.The invention relates to a concrete block for delimiting a playing field provided with an artificial turf, with a slot extending over the entire length of the stone for fixing an edge strip of the artificial turf through anchoring elements inserted into the slot, the slot being connected to a water drain.

Es ist ein Betonformstein dieser Art bekannt (DE-A 2656300), bei dem der Randstreifen des Kunstrasens auf einer oberen horizontalen Randfläche aufliegt, die gegenüber der jenseits des durchgehenden Schlitzes liegenden oberen horizontalen Fläche des Betonformsteins nach unten versetzt angeordnet ist. Dieser Randstreifen wird an dem Betonformstein durch ein mehrteiliges Randprofil festgelegt, das sich an den Randstreifen abstützt, in den Schlitz eingreifende Zapfen und in Abstand voneinander angeordnete Lagerklötze aufweist, die einen Durchlass für das Regenwasser zur Ablaufrinne begrenzen. Eine sichere Halterung des Randstreifens des Kunstrasens bei einer zum Spielfeld gerichteten Zugbelastung ist bei dieser Ausführung nicht gegeben. Es kommt hinzu, dass dasden Randstreifen abdekkende Randprofil in seinem Aufbau relativ kompliziert ist.A concrete block of this type is known (DE-A 2656300), in which the edge strip of the artificial turf rests on an upper horizontal edge surface which is offset downwards from the upper horizontal surface of the concrete block lying beyond the continuous slot. This edge strip is fixed to the concrete block by a multi-part edge profile, which is supported on the edge strip, has spigots engaging in the slot and spaced-apart bearing blocks that limit a passage for the rainwater to the gutter. This design does not provide secure support for the edge strip of the artificial turf when the tensile load is directed towards the playing field. In addition, the structure of the edge profile covering the edge strip is relatively complicated.

Der Erfindung liegt die Aufgabe zugrunde, einen Betonformstein zur Begrenzung eines Kunstrasenspieifeldes so zu gestalten, dass der Randstreifen des Kunstrasens mit geringem konstruktiven Aufwand festgespannt, das Oberflächenwasser zwischen den Spannelementen abgeführt werden kann und ein Nachspannen des Kunstrasens möglich ist.The invention has for its object to design a concrete block to delimit an artificial turf field so that the edge strip of the artificial turf is clamped with little design effort, the surface water can be removed between the clamping elements and retensioning of the artificial turf is possible.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Schlitz keilförmig ausgebildet ist, an einer Seite eine unterschnittene Fläche aufweist und dass als Verankerungselemente in dem Schlitz zum Festspannen des Randstreifens gegen die unterschnittene Seite des Schlitzes in Abstand voneinander Keile mit jeweils einer der Unterschneidung zugeordneten Stufe angeordnet sind.This object is achieved according to the invention in that the slot is wedge-shaped, has an undercut surface on one side and that as anchoring elements in the slot for tightening the edge strip against the undercut side of the slot, wedges are spaced apart from one another, each associated with the undercut Stage are arranged.

Die Keile bilden stirnseitige Begrenzungsflächen für im Bereich des keilförmigen Schlitzes vorgesehene Entwässerungskanäle, die, da der Abstand der Keile wesentlich grössersein kann als die Länge der einzelnen Keile, einen relativ grossen Querschnitt aufweisen können. Durch diese Entwässerungskanäle kann im Randbereich des Spielfeldes somit eine intensive Entwässerung vorgenommen werden. Durch die Anordnung einer unterschnittenen Fläche in dem Wandbereich des keilförmigen Schlitzes, an der der Randstreifen des Kunstrasens angelegt und dann mittels der Keile festgespannt wird, und durch die Ausrüstung der Keile mit einer Stufe, die der Unterschneidung zugeordnet ist, wird für die Festlegung des Randstreifens des Kunstrasens nicht nur ein dem Keilanzug entsprechender Kraftschluss, sondern auch ein Formschluss erzeugt. Dieser gewährleistet, dass auch bei einer Zugbeanspruchung der Kunstrasenbahn zum Spielfeld hin ein Lösen der Verspannung nicht auftreten kann und die Keile ihre Höhenlage im Schlitz beibehalten.The wedges form end faces for drainage channels provided in the area of the wedge-shaped slot, which, since the distance between the wedges can be considerably larger than the length of the individual wedges, can have a relatively large cross-section. Through these drainage channels, an intensive drainage can be carried out in the edge area of the playing field. By arranging an undercut surface in the wall area of the wedge-shaped slot, on which the edge strip of the artificial turf is applied and then tightened by means of the wedges, and by equipping the wedges with a step which is assigned to the undercut, the edge strip is fixed the artificial turf not only creates a positive connection corresponding to the wedge suit, but also a positive fit. This ensures that even when the artificial turf is subjected to tensile loads towards the playing field, the tension cannot be released and the wedges maintain their height in the slot.

Die Unterschneidung in einer Wand des Schlitzes bildet für den anliegenden Randstreifen des Kunstrasens zu der oberen Begrenzungskante des Schlitzes eine zweite Spannkante. Um diese zweite Spannkante wird der Randstreifen auch zwischen zwei benachbarten Keilen gezogen, so dass die Gefahr einer Faltenbildung in der Kunstrasenbahn gering ist.The undercut in a wall of the slot forms a second tensioning edge for the adjoining edge strip of the artificial turf to the upper boundary edge of the slot. The edge strip is also drawn between two adjacent wedges around this second tensioning edge, so that the risk of wrinkling in the artificial turf track is low.

Sofern ein Nachspannen eines verlegten Kunstrasens erforderlich sein sollte, da im Kunstrasen durch unterschiedliche Temperaturen Beulen aufgetreten sind, können die mit Hammerschlägen in den keilförmigen Schlitz des Betonformsteins eingetriebenen Keile mit einem Spezialwerkzeug in einfacher Weise gelöst werden. Durch dieses Spezialwerkzeug werden die Keile ausgehebelt.If it is necessary to retension an installed artificial turf, as bumps have occurred in the artificial turf due to different temperatures, the wedges driven into the wedge-shaped slot of the concrete block with hammer blows can be easily removed with a special tool. The wedges are levered out by this special tool.

Das Ableiten des Oberflächenwassers erfolgt durch die zwischen den Keilen vorgesehenen Entwässerungskanäle in darunter verlaufende Rinnenkanäle oder über Abflussrohre in die unterirdischen Dränage.The surface water is drained off through the drainage channels provided between the wedges into gutter channels running underneath or via drain pipes into the underground drainage.

Im folgenden wird der Gegenstand der Erfindung anhand der Zeichnungen I bis III in Ausführungsbeispielen näher beschrieben.The subject matter of the invention is described in more detail below with reference to drawings I to III in exemplary embodiments.

Die Zeichnung I stellt einen Betonformstein dar, der z.B. aus einem Kunststoffbeton hergestellt ist. Die Fig. 1 zeigt diesen Betonformstein im Querschnitt. im Bereich eines Wasserablaufrohres 5. In der Fig. 2 ist ein Längsschnitt nach der Linie C- D in der Fig. 1 dargestellt, die einen Schnitt nach der Linie A-B der Fig. 2 bitdet.Drawing I represents a concrete block that e.g. is made of a plastic concrete. Fig. 1 shows this concrete block in cross section. in the area of a water drain pipe 5. FIG. 2 shows a longitudinal section along the line C-D in FIG. 1, which includes a section along the line A-B of FIG. 2.

Der Betonformstein ist konstruktiv so gestattet, dass er wie ein normaler Kantenstein versetzt werden kann. Die seitlichen Ausnehmungen 9 und der verbreiterte Fuss 10 dienen zugleich als Gewichts-und Materialeinsparung und zur guten Verankerung im Beton.The shaped concrete block is structurally permitted so that it can be moved like a normal edge stone. The lateral recesses 9 and the widened foot 10 also serve to save weight and material and for good anchoring in the concrete.

In der Fig. 1 ist die neben der Rasenfläche liegende Oberkante des Betonformsteins etwas tiefer ausgebildet, so dass z.B. ein angrenzender Kunststoffbelag 12 (eine Laufbahn) bis an den Schlitz 2 des Betonformsteins herangeführt werden kann. Es entsteht somit, ähnlich wie bei dem Ausführungsbeispiel nach der Fig. 3, eine weiche, einer Verletzungsgefahr entgegenwirkende Oberkante.In Fig. 1, the upper edge of the concrete block lying next to the lawn is formed somewhat lower, so that e.g. an adjacent plastic covering 12 (a track) can be brought up to the slot 2 of the concrete block. This results, similar to the exemplary embodiment according to FIG. 3, in a soft upper edge which counteracts the risk of injury.

Die Zeichnung 11, in der die Fig. 4 einen Schnitt nach der Linie E-F in der Fig. 5 und die Fig. 5 eine Draufsicht zu der Fig. 4 darstellt, zeigt einen zweiteiligen Betonformstein, bei dem das Unterteil mit einem Rinnenkanal 4 versehen ist, während das Oberteil mit dem Schlitz 2 ausgerüstet ist und eine Abdeckung für den Rinnenkanal 4 bildet. Dieser Betonformstein wird vornehmlich dort eingebaut, wo neben dem Rasenspielfeld eine tiefer liegende Laufbahn vorgesehen ist, die oberflächig entwässert werden muss. Der Wassereinlauf ist mittels Pfeilen dargestellt. Er verläuft über die Einlaufschlitze 11 zum Rinnenkanal 4. Die Fig. 5 zeigt in der Draufsicht zur Fig. 4 den durchlaufenden Schlitz 2 und die Anordnung der in den Schlitz 2 durch Hammerschläge eingetriebenen Keile 3, deren Abstand voneinander gewählt werden kann. In der Zeichnung 111 ist ein weiteres Ausführungsbeispiel für den Keil 3 dargestellt, der aus einem Kunststoffmaterial hergestellt werden kann. Die Fig. 7 zeigt eine perspektivische Darstellung, in der die beidseitige Verzahnung 6 und die einseitig ausgebildete Stufe 3a sichtbar sind. Die Fig. 8 zeigt einen Querschnitt mit einer Darstellung des Randstreifens des Kunstrasens 1. Hierbei erkennt man, wie sich der elastische Kunstrasen 1 durch die einseitig ausgebildete Stufe 3a des Keils 3 an die unterschnittene Fläche 2a drückt und somit sicher festgehalten wird.Drawing 11, in which FIG. 4 shows a section along the line EF in FIG. 5 and FIG. 5 shows a plan view of FIG. 4, shows a two-part concrete block in which the lower part is provided with a channel 4 , while the upper part is equipped with the slot 2 and forms a cover for the channel 4. This concrete block is mainly installed where there is a lower-lying track next to the grass field, which must be drained on the surface. The water inlet is shown by arrows. It runs through the inlet slots 11 to the channel channel 4. FIG. 5 shows a top view of FIG. 4, the continuous slot 2 and the arrangement of the wedges 3 driven into the slot 2 by hammer blows, the spacing of which can be selected from one another. In the drawing 111 another embodiment of the wedge 3 is shown, which can be made of a plastic material. FIG. 7 shows a perspective illustration in which the toothing 6 on both sides and the step 3a formed on one side are visible. 8 shows a cross section with an illustration of the edge strip of the artificial turf 1. Here one can see how the elastic synthetic turf 1 presses against the undercut surface 2a through the step 3a of the wedge 3 formed on one side and is thus securely held.
