Above the sheet (10) equipped with tufts (11) there lies a load-equalising sheet (13) which supports the fibre pile (16) or the like, anchored in latex or the like, from below with a stiffening interlayer of bitumen (14) or the like. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Fußbodenbelag mit einem in einer Latexschicht o. dgl. verankerten Faserflor o. dgl. als obere Laufschicht mit einer weicheren Unterschicht, bei dem eine untere, mit Noppen aus einer Gewirke- oder Gewebe­bahn gebildeten Platte vorgesehen ist, deren Noppen in Rei­hen mit Abstand voneinander unter Bildung von Kabelkanälen einseitig vorstehen.The invention relates to a floor covering with a fiber web or the like anchored in a latex layer or the like as an upper running layer with a softer underlayer, in which a lower plate is provided, which is formed with knobs from a knitted or woven web, the knobs of which protrude on one side in rows at a distance from each other to form cable ducts.

Eine derartige Platte aus einer Gewirke- oder Gewebebahn, deren Fäden aus mit Kunstharz beschichteten oder impräg­nierten Chemie-oder Naturfaser bestehen, zeigt eine hohe Stabilität bei geringem Gewicht.Such a panel made of a knitted or woven web, the threads of which consist of synthetic resin-coated or impregnated chemical or natural fibers, shows high stability with low weight.

Aufgabe der Erfindung ist es, einen derartigen Fußbodenbe­lag der vorgenannten Gattung dahingehend zu verbessern, daß bei verhältnismäßig einfacher maschineller Herstellung und Bodenverlegung mit Hilfskräften ein auf- und ausroll­barer, aus Einzelbahnen oder Fliesen (Platten) gebildeter Fußbodenbelag geschaffen wird, der neben einem verhältnis­mäßig geringen spezifischen Gewicht eine hohe Trittfestig­ keit und Gewichtsbelastbarkeit aufweist sowie auch Er­schütterungen dämpft. Weiterhin soll der Fußbodenbelag einen geringen elektrischen Durchgangswiderstand bei guter Erdableitungsmöglichkeit aufweisen.The object of the invention is to improve such a floor covering of the aforementioned type in such a way that, with relatively simple mechanical production and floor laying with auxiliary workers, a roll-up and roll-out floor covering formed from individual sheets or tiles (slabs) is created, which in addition to a relatively low specific Weight a high step resistance strength and weight-bearing capacity and also dampens vibrations. Furthermore, the floor covering should have a low electrical volume resistance with a good possibility of ground discharge.

Gemäß der Erfindung wird diese Aufgabe bei einem Fußboden­belag der vorgenannten Gattung dadurch gelöst, daß auf der Unterseite der mit nach oben weisenden Noppen ausgestatteten Platte eine bodenseitige Wirrfaserschicht aus Natur- und/oder Chemiefasern angeordnet ist und daß über der mit Noppen aus­gestatteten Platte eine belastungsausgleichende Platte liegt, die den in Latex o. dgl. verankerten Faserflor mit einer da­runter angeordneten versteifenden Zwischenschicht aus Bitumen o. dgl. trägt.According to the invention, this object is achieved with a floor covering of the aforementioned type in that a bottom-side tangled fiber layer made of natural and / or chemical fibers is arranged on the underside of the plate equipped with upwardly facing knobs and that a load-compensating plate is provided over the plate equipped with knobs lies, which bears the fiber web anchored in latex or the like with a stiffening intermediate layer of bitumen or the like arranged underneath.

Ein derartiger Fußbodenbelag zeigt unter Bildung vorteil­hafter Kanäle für elektrische oder optische Kabel eine ver­hältnismäßig dünne und damit wenig Raum einnehmende Aus­bildung, der einerseits widerstandsfähig bei höheren Be­lastungen ist und andererseits hohe Isolationswerte hat.Such a floor covering shows, with the formation of advantageous channels for electrical or optical cables, a relatively thin and thus occupying little space, which on the one hand is resistant to higher loads and on the other hand has high insulation values.

Ein solcher Fußbodenbelag dämpft insbesondere auch Erschüt­terungen, die einerseits von aufgestellten Maschinen o. dgl. ausgehen oder andererseits von außen an den Fußboden anlaufen können.Such a floor covering in particular also dampens vibrations which, on the one hand, originate from installed machines or the like or, on the other hand, can run up against the floor from the outside.

Bei einer bevorzugten Ausführungsform haftet die bodensei­tige Wirrfaserschicht an einer zunächst weichen, dann sich erhärtenden, in die Noppen eingefüllten Füllmasse, vorzugs­weise aus Faserzement.In a preferred embodiment, the bottom-side tangled fiber layer adheres to an initially soft, then hardening filling compound, preferably made of fiber cement, which is filled into the knobs.

Gemäß eines weiteren Ausführungsbeispiels der Erfindung ist auf der Oberseite der Noppen die belastungsausgleichende Platte aus Metall o dgl. lösbar aufgeklebt, auf welcher der Faserflor o. dgl. mit seiner Schicht aus Latex o. dgl. aufgelegt ist. Unterseitig dieser Latexschicht ist eine festigkeitsverstärkende Schicht aus sich erhärtendem Bitumen o. dgl. gebildet.According to a further exemplary embodiment of the invention, the load-compensating plate made of metal or the like, on which the fiber pile or the like with its layer of latex or the like is placed, is releasably adhered to the top of the knobs. On the underside of this latex layer is one strength-enhancing layer formed from hardening bitumen or the like.

Bis auf die belastungsausgleichenden Platten und Teppich­fliesen sind alle Schichten eines derartigen Fußbodenbe­lages so ausgebildet, daß sie aufgerollt transportiert und gelagert werden können.Except for the load-compensating panels and carpet tiles, all layers of such a floor covering are designed so that they can be rolled up and transported and stored.

Die bodenseitige Wirrfaserschicht ist vliesförmig und elas­tisch und kann aus Chemiefasern wie Polyester, Polypropylen, Polyacryl o. dgl. bestehen.The bottom tangled fiber layer is fleece-shaped and elastic and can consist of synthetic fibers such as polyester, polypropylene, polyacrylic or the like.

Weitere Merkmale ergeben sich aus den Unteransprüchen.Further features emerge from the subclaims.

Der Schutz erstreckt sich nicht nur auf die Einzelmerkmale, sondern auch auf deren Kombination.The protection extends not only to the individual features, but also to their combination.

Auf der Zeichnung sind Ausführungsbeispiele des Fußboden­belages dargestellt. Es zeigen:

  • Fig. 1 einen Querschnitt durch einen Fußbodenbelag mit zwischen Noppen verlaufenden Kabelkanälen mit beidseitigen Abdeckschichten,
  • Fig. 2 eine abgeänderte Ausführung mit zusätzlich zwischen­geschalteter Wirrfaserschicht.

  • Fig. 2 shows a modified version with an additional interposed tangled fiber layer.

Mit (10) ist eine Platte aus einer Gewirke- oder Gewebebahn (mit Maschen) bezeichnet, deren nach oben vorstehende, im Tiefziehverfahren hergestellte Noppen (11) konisch ausge­bildet sind und die bodenseitig auf einer Auflage- bzw. Haftfläche aus Wirrfasern (12) aufliegt und nach oben eine Metallplatte (13) mit unterseitigem Haftkleber haftend aber lösbar trägt.With (10) is a plate made of a knitted or woven web (with stitches), the upstanding protruding knobs (11) are conical and the bottom rests on a support or adhesive surface made of tangled fibers (12) and upwards carries a metal plate (13) with adhesive on the underside, which is adhesive but detachable.

Die Noppen (11) haben eine Höhe von ca. 15 mm bodenseitig und ihr Durchmesser beträgt untenseitig ca. 10 - 24 mm und obenseitig ca. 8 - 12 mm. Bei dieser mit Noppen (11) ausgeprägten Platte (10) hat das Gewebe oder Gewirke eine Dicke von 0,6 - 1,2 mm. Die Weite der Maschen beträgt zwischen 0,8 - 1,2 mm. Die Fäden dieser Gewirke, Gewebe können mit Carbonfäden oder Metallfäden gesponnen sein, die neben ihrer elektrischen Leitfähigkeit auch zur Erhöhung der Festigkeit beitragen.The knobs (11) have a height of approx. 15 mm on the base and their diameter is approx. 10 - 24 mm on the underside and approx. 8 - 12 mm on the top. In this plate (10) with knobs (11), the woven or knitted fabric has a thickness of 0.6-1.2 mm. The width of the mesh is between 0.8 - 1.2 mm. The threads of these knitted fabrics can be spun with carbon threads or metal threads, which in addition to their electrical conductivity also contribute to increasing the strength.

Die Metallplatte (13) kann aus Stahlblech o. dgl. wie aluminiumplattierter oder verzinkter Stahlplatte bestehen. Sie kann als Leichtmetallplatte wie Aluminiumplatte oder auch als faserverstärkte Kunststoffplatte ausgebildet sein. Sie hat eine Dicke von ca. 1 - 1,3 mm. Auf dieser Metall­platte (13) liegt die elastische Laufschicht, die unten­seitig eine sich erhärtende Bitumenschicht (14) hat und dann darüber eine Latexschicht (15), in welcher der oben außenseitige Faserflor (16) in bekannter Weise eingebettet ist. Die drei Schichten (14, 15, 16) der Laufschicht sind unlösbar miteinander bereits herstellungsmäßig verbunden.The metal plate (13) can consist of sheet steel or the like, such as aluminum-plated or galvanized steel plate. It can be designed as a light metal plate such as an aluminum plate or as a fiber-reinforced plastic plate. It has a thickness of approx. 1 - 1.3 mm. The elastic running layer, which has a hardening bitumen layer (14) on the underside, lies on this metal plate (13) then over it a latex layer (15) in which the fibrous web (16) on the outside is embedded in a known manner. The three layers (14, 15, 16) of the overlay are already inextricably linked to one another in terms of manufacture.

Die Noppen (11) sind gefüllt mit einem mit Fasern durch­setzten Zement (Beton) (17), der zunächst weich eingefüllt ist und dann erhärtet. Dabei faßt vorzugsweise diese Füll­masse (17) in die Maschenöffnungen der Noppen (11) ver­stärkend ein.The knobs (11) are filled with a fiber-interspersed cement (concrete) (17), which is first filled in gently and then hardened. This filling compound (17) preferably encloses reinforcingly in the mesh openings of the knobs (11).

Auf die zunächst weiche freie Fläche des faserverstärkten Zements (17) ist ein Wirrfaservlies (12) als Auflageschicht eingedrückt, das bei Erhärtung des Zements an dessen breiter Fläche unverschiebbar anhaftet.On the initially soft free surface of the fiber-reinforced cement (17), a random fiber fleece (12) is pressed as a support layer, which adheres to the wide surface of the cement when the cement hardens.

Diese Wirrfaserschicht (12) besteht ebenfalls aus Chemie­fasern oder Naturfasern und kann eine Dicke von 0,2 - 3 mm, vorzugsweise 0,5 - 2 mm, aufweisen; sie wiegt zwischen 40 und 200 g/m².This tangled fiber layer (12) also consists of man-made fibers or natural fibers and can have a thickness of 0.2-3 mm, preferably 0.5-2 mm; it weighs between 40 and 200 g / m².

Diese Wirrfaserschicht (12) deckt einerseits die nach unten unbedeckten Flächen des Faserzementes (17) ab, welche den Noppen (11) eine hohe Druckfestigkeit verleiht.This tangled fiber layer (12) covers on the one hand the uncovered areas of the fiber cement (17), which gives the knobs (11) a high compressive strength.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel ist zusätzlich zwischen der Stirnseite der Noppen (11) und der Platte (13) eine Wirrfaserschicht (18) eingeschaltet, welche zusätzlich der Schalldämmung dient.In the embodiment shown in Fig. 2, an additional fiber layer (18) is additionally switched between the end face of the knobs (11) and the plate (13), which additionally serves for sound insulation.

Ein erfindungsmäßiger Fußbodenbelag ist gemäß ASTM 648 E oder DIN 4102 schwer entflammbar ausgebildet.A floor covering according to the invention is designed to be flame-retardant in accordance with ASTM 648 E or DIN 4102.

Die in den Noppen (11) weich eingefüllten und sich erhär­tenden Faserzementblöckchen (17) durchdringen die Maschen­öffnungen der Noppen (11).The fiber cement blocks (17), which are softly filled and hardening in the knobs (11), penetrate the mesh openings of the knobs (11).

Die Fäden des Gewirkes (oder Gewebes) sind vorzugsweise mit einem sich erhärtenden Kunststoff beschichtet oder imprägniert. Ausführungsbeispiel.
