Description

Flüssigkeitsdurchlässiger Belag Liquid-permeable covering
Die Erfindung betrifft einen flüssigkeitsdurchlässigen Be¬ lag für begeh- und befahrbare Böden u.dgl. Es ist bekannt, zur Abdeckung von Böden u.dgl. Flächenbe¬ festigungselemente einzusetzen, die flüssigkeitsdurchlässig sind, damit Oberflächenwässer u.dgl. abgeleitet werden können. Derartige Elemente werden z.B. aus Kunststein hergestellt und im Verband verlegt. Dies erfordert relativ aufwendige Formungs- Vorgänge für die Elemente und einen beträchtlichen Arbeitsein¬ satz bei deren Verlegung mit entsprechend hohen Kosten. Außer¬ dem erschwert das Gewicht der Elemente deren Handhabung und Transport.The invention relates to a liquid-permeable covering for floors that can be walked on and driven over and the like. It is known to cover floors and the like. To use surface fastening elements which are permeable to liquids, so that surface water and the like. can be derived. Such elements are e.g. made of artificial stone and laid in a bandage. This requires relatively complex shaping processes for the elements and a considerable amount of work when laying them with correspondingly high costs. In addition, the weight of the elements complicates their handling and transportation.
Die vorliegende Erfindung zielt darauf ab, einen als Fil- ter wirksamen flüssigkeitsdurchlässigen Belag zu schaffen, der kostengünstig hergestellt sowie auf einfache Weise und rasch verlegt werden kann. Der Belag soll zugleich eine einwandfreie Flüssigkeitsableitung sicherstellen.The aim of the present invention is to create a liquid-permeable covering which acts as a filter and which can be produced inexpensively and laid quickly and easily. The covering is also intended to ensure proper fluid drainage.
Der erfindungsgemäße Belag zeichnet sich durch die Kombination der Merkmale aus, daß er aus zumindest zwei miteinander flächig, vorzugsweise durch Klebung verbundenen La¬ gen aus zelligem elastischem Kunststoff gebildet ist, wobei jede bodenseitige Lage wesentlich dicker als jede oberflächenseitige Lage ist, welche vorzugsweise wesentlich kleinere Zellen als die bodenseitige Lage hat, daß auf der den Boden berührenden Belagseite in der zugeordneten Lage mit gegenseitigem Abstand parallel zueinander verlaufende, vorzugs¬ weise auch einander kreuzende Flüssigkeitsableitkanäle ausge¬ bildet sind, daß sich von den Flüssigkeitsableitkanälen in gegenseitigen Abständen weitere Kanäle durch die bzw. jede bodenseitige Lage hindurch erstrecken, wobei die weiteren Kanä¬ le in der bzw. jeder bodenseitigen Lage in diese eingeschnitten oder eingeformt sind und sich vorzugsweise konisch oder stufen¬ förmig nach unten öffnen. Diese Ausbildung sichert bei an sich beliebig großer Aus¬ bildung und relativ geringem Gewicht sowie elastischer Verform¬ barkeit des Belages eine optimale Filterung und Flüssigkeitsab¬ leitung. Erfindungsgemäß wird bei geringem Verschleiß eine hohe Standzeit erreicht und sichergestellt, daß die Drainagekanäle und Materialzellen nicht versiegeln.The covering according to the invention is characterized by the combination of the features that it is formed from at least two layers of cellular elastic plastic which are connected to one another, preferably by adhesive bonding, each bottom-side layer being substantially thicker than each surface-side layer, which is preferably much smaller Cells as the bottom layer has that liquid discharge channels running parallel to one another, preferably also crossing each other, are formed on the covering side touching the floor in the assigned position with a mutual spacing, so that further channels are formed from the liquid discharge channels through the or extend through each bottom-side layer, the further channels in the or each bottom-side layer being cut or molded into it and preferably opening downwards in a conical or step-like manner. This design ensures optimum filtering and liquid drainage with an arbitrarily large design and relatively low weight and elastic deformability of the covering. According to the invention, high wear is low Service life achieved and ensured that the drainage channels and material cells do not seal.
Gemäß einer bevorzugten Ausführungsform der Erfindung sind in der bzw. jeder oberflächenseitigen Lage Durchtrittsöffnungen ausgebildet, die in die sich durch die bzw. jede bodenseitige Lage hindurch erstreckenden Kanäle münden. Hiedurch wird sichergestellt, daß bei Durchbiegung der oberflächenseitigen Lage unter Belastung sich die Durchtrittsöffnungen nach unten zu erweitern und jegliche Verstopfung vermieden wird. Gemäß einer weiteren bevorzugten Ausführungsform der Er¬ findung ist der Belag in Form einer aufrollbaren Bahn ausgebil¬ det, was ein Aufrollen des Belages und einen einfachen Trans¬ port sowie ein rasches Verlegen desselben ermöglicht.According to a preferred embodiment of the invention, passage openings are formed in the or each surface-side layer which open into the channels extending through the or each bottom-side layer. This ensures that when the surface-side layer bends under load, the passage openings widen downward and any blockage is avoided. According to a further preferred embodiment of the invention, the covering is designed in the form of a roll that can be rolled up, which enables the covering to be rolled up and easy to transport and to be laid quickly.
Nach einem weiteren Merkmal der Erfindung sind die Lagen des Belages aus einem zelligen Elastomer gebildet, wie einem Polyurethan (Polyätherurethan, z.B. einem Sylomer®) . Derartige Elastomere können z.B. eine Dichte von 150 kg/m3 bis 680 kg/m3 haben und gewährleisten eine vollflächige Kraftübertragung. Da¬ neben zeigen sie ein besonders gutes Verhalten unter dynami- sehen Belastungen, wobei sie zunehmend steifer werden. Die ge¬ nannten Elastomere sind gegen Wasser, öl, Fett usw. beständig.According to a further feature of the invention, the layers of the covering are formed from a cellular elastomer, such as a polyurethane (polyether urethane, for example a Sylomer® ) . Such elastomers can have a density of 150 kg / m 3 to 680 kg / m 3 , for example, and ensure full-area power transmission. In addition, they show particularly good behavior under dynamic loads, whereby they become increasingly stiffer. The mentioned elastomers are resistant to water, oil, fat, etc.
Im Rahmen der Erfindung kann der Belag natürlich auch aus einzelnen Elementen beliebiger Größe aufgebaut werden, die ge¬ gebenenfalls im Verband verlegt werden. Die als Belagoberfläche dienende dünne oberflächenseitige Lage wird, wie schon erwähnt, zweckmäßig durch Klebung mit der darunterliegenden bodenseitigen Lage verbunden. Es können im Rahmen der Erfindung aber auch mehrere dünne Lagen bzw. mehr als eine bodenseitige Lage vorgesehen werden und zweckmäßig un- tereinander durch Klebung verbunden sein.In the context of the invention, the covering can of course also be built up from individual elements of any size, which may be installed in the association. The thin surface layer serving as covering surface is, as already mentioned, expediently connected to the underlying layer on the bottom by gluing. Within the scope of the invention, however, a plurality of thin layers or more than one bottom layer can also be provided and expediently connected to one another by adhesive bonding.
Die zur Flüssigkeitsableitung dienenden Kanäle können durch Formung, z.B. beim Gießen des Belages, oder auf mechani¬ schem Wege, z.B. mittels eines Wasserstrahles, ausgebildet wer¬ den. Erfindungsgemäß wird durch das elastische Verhalten des Belages beim Begehen oder Befahren durch "Quetschvorgänge" der Drainageeffekt und die Selbstreinigung zusätzlich begünstigt. Insbesondere wird durch Formänderungsvorgänge sichergestellt, daß in die Abflußöffnungen eindringende Partikel weitertrans¬ portiert werden. Ein Versiegeln ist daher auszuschließen.The channels used to drain the liquid can be formed by shaping, for example when pouring the covering, or by mechanical means, for example by means of a water jet. According to the invention, the drainage effect and self-cleaning are additionally promoted by the elastic behavior of the covering when walking or driving through “squeezing processes”. In particular, by means of deformation processes, it is ensured that particles penetrating into the discharge openings are transported further. Sealing must therefore be ruled out.
Zur Begünstigung der Verformung wie auch der Wasserablei¬ tung tragen die Flüssigkeitsableitkanäle an der Unterseite des Belages bei. Diese Kanäle können, wie erwähnt, auch in kreuzen¬ der Richtung verlaufen, so daß ein Netz von Kanälen vorhanden ist.The liquid drainage channels on the underside of the covering contribute to favoring the deformation and the water drainage. As mentioned, these channels can also run in a cross direction, so that a network of channels is present.
Weitere Merkmale der Erfindung werden nachfolgend an Aus¬ führungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert, in welchen dieFurther features of the invention are explained in more detail below using exemplary embodiments with reference to the drawings, in which the
Fig. 1 und 2 bahnförmig ausgebildete Beläge gemäß der Erfindung im Schnitt zeigen.Fig. 1 and 2 web-shaped coverings according to the invention show in section.
Jeder der gezeigten Beläge hat eine bodenseitige Filter¬ körperlage 1 und eine mit dieser vollflächig, z.B. durch Kle- bung, verbundene oberflächenseitige Filterkörperlage 2, die erheblich dünner als die bodenseitige läge 1 ist. Beide Lagen 1, 2 sind aus einem hochabriebfesten zelligen Elastomer, z.B. einem Polyurethan, gebildet, das flüssigkeitsdurchlässig ist. Die dünnere, oberflächenseitige Lage 2 hat bei den Ausführungs- formen nach Fig. 1 wesentlich kleinere Zellen als die dickere bodenseitige Lage 1. Bei der Ausführungsform nach Fig. 2 be¬ stehen beide Lagen aus dem gleichen zelligen Material.Each of the coverings shown has a filter body layer 1 on the bottom side and one with this over the entire surface, e.g. by gluing, connected surface-side filter body layer 2, which is considerably thinner than the bottom-side layer 1. Both layers 1, 2 are made of a highly abrasion-resistant cellular elastomer, e.g. a polyurethane, which is permeable to liquids. 1 has much smaller cells than the thicker bottom layer 1. In the embodiment according to FIG. 2, both layers are made of the same cellular material.
Wie die Fig. 1 und 2 zeigen, sind in der den Boden berüh¬ renden Belagseite bzw. in der Unterseite der Lage 1 parallel zueinander verlaufende Kanäle 3 ausgebildet, die die Verform¬ barkeit des Belages begünstigen und zur Flüssigkeitsableitung dienen. Bei den dargestellten Ausführungsformen kann auch eine kreuzende Schar von parallelen Kanälen 3' vorgesehen sein, so daß ein Netz von Kanälen entsteht. Von den Kanälen 3 bzw. 3' können sich mit gegenseitigem Abstand weitere Kanäle 4 durch die bodenseitige Lage 1 hindurch erstrecken, wie Fig. 2 zeigt. Die Flüssigkeitsableitkanäle 3 bzw. 3' und die weiteren Kanäle 4 können durch Formung, z.B. beim Gießen des Belages, oder auf mechanischem Wege, z.B. mittels eines Wasserstrahles oder durch Stanzen ausgebildet werden. Die Kanäle 4 können sich auch ko¬ nisch oder stufenförmig nach unten öffnen. In der oberflächenseitigen Lage 2 sind Durchtrittsöffnun¬ gen 5 ausgebildet, die in die sich durch die bzw. jede boden¬ seitige Lage hindurch erstreckenden Kanäle münden.As shown in FIGS. 1 and 2, channels 3 which run parallel to one another are formed in the covering side touching the floor or in the underside of the layer 1, which favor the deformability of the covering and serve for liquid drainage. In the illustrated embodiments, a crossing set of parallel channels 3 'can also be provided, so that a network of channels is created. From the channels 3 and 3 ', further channels 4 can extend at a mutual distance through the bottom layer 1, as shown in FIG. 2. The liquid discharge channels 3 or 3 'and the further channels 4 can be formed by shaping, for example when pouring the covering, or by mechanical means, for example by means of a water jet or by punching. The channels 4 can also open downwards in a conical or step-like manner. Passage openings 5 are formed in the surface-side layer 2, which open into the channels extending through the or each floor-side layer.
Der dargestellte Belag kann als Bahn oder als Einzelele- ment ausgebildet sein, die bzw. das aufgerollt werden kann. Im Rahmen der Erfindung sind verschiedene Abwandlungen des erläu¬ terten Ausführungsbeispieles möglich, insbesondere was die ver¬ wendeten Materialien und die Anzahl der Lagen betrifft. So kann eine Mehrzahl von bodenseitigen bzw. oberflächenseitigen Lagen vorgesehen werden, die alle gleich große Zellen haben, oder bei denen die Zellengröße in jeder der aufeinanderfolgenden Lagen von oben nach unten zunimmt.The covering shown can be designed as a web or as an individual element that can be rolled up. Various modifications of the exemplary embodiment explained are possible within the scope of the invention, in particular as regards the materials used and the number of layers. Thus, a plurality of layers on the bottom or surface can be provided, all of which have cells of the same size, or in which the cell size increases in each of the successive layers from top to bottom.
Der erfindungsgemäße Belag bzw. Teile desselben kann im Rahmen der Erfindung auch zum Ausfüllen von stabilen rahmen- artigen Bodenbefestigungselementen, Flüssigkeitsablaufgittern u.dgl. verwendet werden. The covering according to the invention or parts thereof can also be used within the scope of the invention for filling stable frame-like floor fastening elements, liquid drain grids and the like. be used.
