Description

Die Erfindung bezieht sich gattungsgemäß auf einen bahnför­migen, vegetationshemmenden Erdbodenbelag, der eine Kunst­stoffolie aus Polyurethan oder vorzugsweise Polyäthylen hoher Dichte aufweist. Solche Kunststoffolien besitzen z. B. eine Dicke von 80 µm oder mehr und eine Bahnbreite von etwa einem Meter. - Derartige vegetationshemmende Erdbodenbeläge werden seit langem in den verschiedensten Gebieten der Landwirt­schaft und Technik eingesetzt.The invention relates generically to a sheet-like, vegetation-inhibiting floor covering that has a plastic film made of polyurethane or preferably high-density polyethylene. Such plastic films have z. B. a thickness of 80 microns or more and a web width of about one meter. - Such vegetation-inhibiting floor coverings have long been used in a wide variety of areas of agriculture and technology.

Insbesondere werden derartige Erdbodenbeläge auch längs Auto­bahnen eingesetzt, z. B. unterhalb der Leitplanken. Die Leit­planken werden von Stützen getragen, die im Abstand von vier Metern angeordnet sind, und die Erdbodenbeläge müssen die Stützen aussparen.In particular, such floor coverings are also used along highways, e.g. B. below the guardrails. The guardrails are supported by supports that are four meters apart, and the floor coverings have to cut out the supports.

Die aus der Praxis bekannten gattungsgemäßen Erdbodenbeläge sind zum Zwecke der Windsicherung zuweilen mit Steinen be­schwert. Nichtsdestoweniger bestehen erhebliche Nachteile. Einerseits beobachtet man im Laufe der Zeit eine Zerstörung der Kunststoffolie durch den Einfluß des Sonnenlichts, insbe­sondere des ultravioletten Anteils im Sonnenlicht, anderer­seits faßt der Wind unter die Bereiche zwischen den nur sin­gulär aufgelegten Steinen. Die Zerstörung von Folien durch ultraviolette Strahlen beruht auf der damit verbundenen star­ken Beschleunigung der Oxidation der Polymerisate, was sich in einem Aufbrechen der Molekülketten auswirkt. Die Intakt­heit der Kunststoffolie ist aber unerläßliche Voraussetzung für die vegetationshemmende Wirkung der gattungsgemäßen Erd­bodenbeläge. Die Resistenz der bekannten Erdbodenbeläge gegen Sonnenlicht und insbesondere Ultraviolettstrahlen sowie deren Windsicherung ist folglich unzureichend, was sich in zu kur­zen Standzeiten äußert.The generic floor coverings known from practice are sometimes weighted with stones for the purpose of wind protection. Nevertheless, there are significant disadvantages. On the one hand, destruction of the plastic film is observed over time due to the influence of sunlight, especially the ultraviolet component in sunlight, on the other hand, the wind reaches under the areas between the stones, which are only singularly placed. The destruction of films by ultraviolet rays is based on the associated strong acceleration of the oxidation of the polymers, which has the effect of breaking the molecular chains. However, the integrity of the plastic film is an essential prerequisite for the vegetation-inhibiting effect of the generic floor coverings. The resistance of the known floor coverings to Sunlight and in particular ultraviolet rays and their wind protection are therefore insufficient, which manifests itself in a short standstill.

Die der Erfindung zugrundeliegende Aufgabe lautet, einen gat­tungsgemäßen Erdbodenbelag so weiter auszubilden, daß er wind­fest und ausreichend resistent gegen Sonnenlicht und insbe­sondere Ultraviolettstrahlen ist.The object underlying the invention is to further develop a generic floor covering so that it is windproof and sufficiently resistant to sunlight and in particular ultraviolet rays.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß auf die Oberfläche der Kunststoffolie eine bituminöse Schutzschicht gegen Sonnenlicht, insbesondere Ultraviolettstrahlen, aufge­bracht ist, die gleichzeitig als Klebschicht ausgebildet ist, und daß durch die Klebschicht außerdem eine Windsicherungs­schicht aus spezifisch schwerem Schüttgut auf der Kunststoff­folie fixiert ist. - Erdbodenbeläge aus mehreren Schichten, bei denen eine oberste Schicht aus schwerem Schüttgut zur Windsicherung besteht sowie das Schüttgut durch ein Binde­mittel fixiert ist, sind an sich bekannt (DE-OS 35 15 144). Allerdings handelt es sich nicht um die bahnförmigen Erdbo­denbeläge mit Kunststoffolie als unterste Lage. Bei der be­kannten Ausführungsform ist die unterste Lage eine Papplage, die mit einem Herbizid imprägniert ist, aber verwittern soll und nach z. B. zwei Vegetationsperioden vom Gras durchwachsen werden soll, welches danach leicht mähbar ist.To achieve this object, the invention teaches that a bituminous protective layer against sunlight, in particular ultraviolet rays, is applied to the surface of the plastic film, which at the same time is designed as an adhesive layer, and that the adhesive layer also fixes a wind protection layer made of specifically heavy bulk material on the plastic film . - Floor coverings of several layers, in which an uppermost layer consists of heavy bulk material for wind protection and the bulk material is fixed by a binder, are known per se (DE-OS 35 15 144). However, it is not the sheet-like floor coverings with plastic film as the bottom layer. In the known embodiment, the bottom layer is a cardboard layer, which is impregnated with a herbicide, but should weather and after z. B. two vegetation periods of grass should grow through, which is then easily mowed.

Die Erfindung beruht auf der Erkenntnis, daß die bituminöse Schutzschicht eine Doppelfunktion ausüben kann. Überraschen­derweise erzielt sie einerseits einen wirksamen Schutz der Kunststoffolie gegen Sonnenlicht, insbesondere gegen ultra­violette Strahlen, sie hält aber andererseits auch eine Wind­sicherungsschicht aus spezifisch schwerem Schüttgut auf der Kunststoffolie fest. Es versteht sich, daß zur Vegetations­hemmung die Kunststoffolie wasserundurchlässig ist. Die Schutz­schicht besteht vorzugsweise aus Straßenbaubitumen, welches sich als Bindemittel im Straßenbau bewährt hat, erfindungs­gemäß aber auch als Schutzschicht funktioniert. Straßenbau­bitumen ist wegen seiner dunklen Farbe vorteilhaft, weil es im Sinne seiner erfindungsgemäßen Schutzfunktion vor Ultra­violettstrahlen als guter Absorber dient. Wenn der Erdboden­belag in Waldgebieten eingesetzt werden soll, empfiehlt es sich, dem Straßenbaubitumen feuerhemmende Stoffe beizugeben. Zur Verbesserung der Bindemittelfunktion der Schutzschicht kann das Straßenbaubitumen mit einem oder mehreren Elasto­meren legiert sein. Zweckmäßigerweise wird die Schutzschicht in beiden Fällen als Emulsion aufgetragen. Sie besitzt im ge­brochenen Zustand vorzugsweise ein Gewicht von etwa 0,4 kg/m². Für die Windsicherungsschicht, die in bevorzugter Ausführungs­form aus steinigem Granulat besteht, ist es ausreichend, daß das Schüttgewicht etwa 5 kg/m² beträgt. Das Granulat kann da­bei Körnungen im Bereich von zwei Millimetern bis zu einigen Zentimetern aufweisen. Die Windsicherungsschicht bewirkt nicht nur eine Windsicherung, sondern auch eine Sicherung gegen Abschwimmen, wenn Wasser unter den Erdbodenbelag ge­langt.The invention is based on the knowledge that the bituminous protective layer can have a double function. Surprisingly, on the one hand it achieves effective protection of the plastic film against sunlight, in particular against ultraviolet rays, but on the other hand it also holds a wind protection layer made of specifically heavy bulk material on the Plastic film firmly. It is understood that the plastic film is impermeable to water to inhibit vegetation. The protective layer preferably consists of road bitumen, which has proven itself as a binder in road construction, but according to the invention also functions as a protective layer. Road construction bitumen is advantageous because of its dark color because it serves as a good absorber in the sense of its protective function against ultraviolet rays according to the invention. If the ground covering is to be used in forest areas, it is advisable to add fire-retardant substances to the road construction bitumen. To improve the binder function of the protective layer, the road bitumen can be alloyed with one or more elastomers. In both cases, the protective layer is expediently applied as an emulsion. When broken, it preferably has a weight of approximately 0.4 kg / m 2. For the wind protection layer, which in a preferred embodiment consists of stony granules, it is sufficient that the bulk density is about 5 kg / m². The granules can have grain sizes in the range from two millimeters to a few centimeters. The wind protection layer not only provides wind protection, but also protection against swimming when water gets under the floor covering.

Eine andere bevorzugte Ausführungsform der Erfindung ist da­durch gekennzeichnet, daß auf die Windsicherungsschicht eine Farbschicht und auf diese eine Abdeckung aus Glaskugeln auf­gebracht ist. Dabei empfiehlt es sich, die Glaskugeln, die einen Durchmesser von etwa 1 mm aufweisen, in dichtester Ku­gelpackung, z. B. aus zumindest zwei Lagen, anzuordnen. Ar­beitet man mit einer Abdeckung aus Glaskugeln, so ergibt sich ein zusätzlicher, beachtlicher Vorteil. Die Glaskugeln tra­gen einerseits zur Windsicherung bei, bewirken aber außerdem nachts eine Lichtreflexion, die im Scheinwerferlicht eines Kraftfahrzeuges die Randstreifen sichtbar macht.Another preferred embodiment of the invention is characterized in that a layer of paint is applied to the wind protection layer and a cover made of glass balls is applied thereon. It is recommended that the glass balls, which have a diameter of about 1 mm, in the densest ball packing, e.g. B. from at least two layers. If you work with a cover made of glass balls, the result is an additional, considerable advantage. The glass balls contribute to wind protection on the one hand, but also cause light reflection at night, which makes the edge strips visible in the headlights of a motor vehicle.

Von besonderem Vorteil ist fernerhin, daß der erfindungsge­mäße Erdbodenbelag auf einfache Weise verlegungstechnisch optimiert werden kann. Zur Vermeidung einer Spaltbildung zwischen nebeneinanderliegenden Bahnen des Erdbodenbelages können deren Längsseiten der Kunststoffolie mit Überlappungs­säumen versehen sein, die zusätzlich Verbindungsausnehmungen enthalten können. Diese Überlappungssäume können durch folien­unterseitiges Umschlagen auch als Randverstärkung eingesetzt sein. Es versteht sich, daß die Kunststoffolie eines erfin­dungsgemäßen Erdbodenbelages auch Querfalten aufweisen kann.It is also particularly advantageous that the floor covering according to the invention can be easily optimized in terms of laying technology. To avoid the formation of a gap between adjacent webs of the floor covering, the long sides of the plastic film can be provided with overlap seams, which can additionally contain connecting recesses. These overlap seams can also be used as edge reinforcement due to the foil underside. It is understood that the plastic film of a floor covering according to the invention can also have transverse folds.

Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert.In the following, the invention will be explained in more detail with reference to a drawing showing only one embodiment.

Die einzige Figur zeigt perspektivisch einen Erdbodenbelag mit steinigem Granulat als Windsicherungsschicht.The only figure shows in perspective a floor covering with stony granules as a wind protection layer.

In der Figur erkennt man einen bahnförmigen, vegetations­hemmenden Erdbodenbelag 1 in perspektivischer Darstellung. Dabei ist auf die Oberfläche 5 der Kunststoffolie 2 eine bituminöse Schutzschicht 3 aufgebracht, die gegen Sonnen­licht, insbesondere Ultraviolettstrahlen schützt. Gleich­zeitig dient diese Schutzschicht 3 als Bindemittelschicht, die eine Windsicherungsschicht 4 aus spezifisch schwerem Schüttgut 6 auf der Kunststoffolie 2 fixiert. Die Schutz­bzw. Bindemittelschicht 3 besteht vorzugsweise aus Straßen­baubitumen oder aus einer Legierung aus Straßenbaubitumen und einem Elastomer. Die darauf fixierte Windsicherungs­schicht 4 besitzt ein Schüttgewicht von etwa 5 kg/m², und be­steht vorzugsweise aus steinigem Granulat 6. Dieses Granulat 6 kann dabei Körnungen im Bereich von zwei Millimetern bis zu einigen Zentimetern aufweisen. - Es versteht sich, daß man zusätzlich in der beschriebenen Weise eine Abdeckung aus Glaskugeln aufbringen kann, die lichtreflektierend wirkt.In the figure, a web-shaped, vegetation-inhibiting floor covering 1 can be seen in a perspective view. A bituminous protective layer 3, which protects against sunlight, in particular ultraviolet rays, is applied to the surface 5 of the plastic film 2. At the same time, this protective layer 3 serves as a binder layer, which fixes a wind protection layer 4 made of specifically heavy bulk material 6 on the plastic film 2. The protection or Binder layer 3 preferably consists of road construction bitumen or of an alloy of road construction bitumen and an elastomer. The wind protection layer 4 fixed thereon has a bulk density of about 5 kg / m 2, and preferably consists of stony granules 6. These granules 6 can have grains in the range from two millimeters to a few centimeters. - It is understood that you can also apply a cover made of glass balls in the manner described, which has a light reflecting effect.
