Description

Die Erfindung bezieht sich gattungsgemäß auf einen Bodenbelag, insbesondere für Freiflächen und Hallenböden, mit einem Unterbau aus einem aushärtbaren oder abbindefähigen Material sowie metallischen Abdeckplatten.The invention relates generically to a floor covering, in particular for open spaces and hall floors, with a substructure made of a hardenable or settable material and metallic cover plates.

Der aus der Praxis bekannte gattungsgemäße Bodenbelag weist unterseitig ebene Abdeckplatten auf. Die Verankerung der Abdeckplatten mit dem Unterbau ist verbesserungsbedürftig. Auch können Verschiebungen der Abdeckplatten relativ zueinander auftreten.The generic floor covering known from practice has flat cover plates on the underside. The anchoring of the cover plates to the substructure is in need of improvement. Shifts in the cover plates can also occur relative to one another.

Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Bodenbelag so weiter auszubilden, daß die Abdeckplatten miteinander verkettet sowie mit dem Unterbau sicher verbunden sind.The invention has for its object to further develop the generic floor covering so that the cover plates are chained together and securely connected to the substructure.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Abdeckplatten umfangsseitig angeformte Verankerungselemente aufweisen, die zahnförmig ineinandergreifen und unter einem spitzen Winkel nach unten abgekantet sind, wobei sie in dem ausgehärteten oder abgebundenen Unterbau verankert sind. Die Verankerungselemente haben erfindungsgemäß eine Doppelfunktion. Zum einen sichern sie Formschluß zwischen den Abdeckplatten und zum anderen stellen sie eine gute Verbindung mit dem Unterbau her. Durch die zahnförmig ineinandergreifenden Verankerungselemente ist ferner eine gleichmäßige Anordnung der Abdeckplatten bei der Verlegung des Bodenbelages gewährleistet.To achieve this object, the invention teaches that the cover plates have circumferentially formed anchoring elements which engage in a tooth-like manner and are folded down at an acute angle, being anchored in the hardened or set substructure. According to the invention, the anchoring elements have a double function. On the one hand, they ensure positive locking between the cover plates and, on the other hand, they establish a good connection with the substructure. The toothed interlocking anchoring elements also ensure a uniform arrangement of the cover plates when laying the floor covering.

Wenn der Bodenbelag große Beanspruchung aufnehmen muß, empfiehlt die Erfindung, daß der Unterbau eine gitterförmige Einlage aus Streckmetall aufweist und daß die Verankerungselemente in die Gittermaschen der Einlage eingreifen. Eine weitere Verbesserung kann dadurch erreicht werden, daß die Einlage und die Abdeckplatten durch Punktverschweißung miteinander verbunden sind. Die Verlegung des Bodenbelages ist auf einfache Weise möglich, indem die Einlage mit aufgeschweißten Abdeckplatten auf einen noch nicht ausgehärteten oder abgebundenen Unterbau aufgelegt und anschließend festgewalzt wird. Die Arbeiten stellen keine besonderen Anforderungen an das Personal.If the flooring has to take up heavy loads, the invention recommends that the substructure is a Has grid-shaped insert made of expanded metal and that the anchoring elements engage in the mesh mesh of the insert. A further improvement can be achieved in that the insert and the cover plates are connected to one another by spot welding. The floor covering can be laid in a simple manner by placing the insert with welded-on cover plates on a not yet hardened or set substructure and then rolling it down. The work places no special demands on the personnel.

Der Unterbau besteht vorzugsweise aus Teermakadam oder Beton. Ein solcher Unterbau, insbesondere aus Teermakadam, bildet eine wirksame Sperre für Umweltgifte, beispielsweise PCB. Der Unterbau verhindert, daß derartige Umweltgifte ins Erdreich oder Grundwasser gelangen. Im Rahmen der Erfindung liegt es, den Bodenbelag nach der Verlegung durch öl- oder säurebeständige Auftragungen zu versiegeln.The substructure is preferably made of tar macaque or concrete. Such a substructure, in particular made of tar macaque, forms an effective barrier for environmental toxins, for example PCBs. The substructure prevents such environmental toxins from reaching the ground or groundwater. It is within the scope of the invention to seal the floor covering after laying by oil or acid-resistant applications.

Soll der Bodenbelag hohe Kräfte aufnehmen, so ist es ferner vorteilhaft, wenn die Abdeckplatten oberseitig vorspringende Verstärkungssicken aufweisen. Derartige Verstärkungssicken erhöhen die Verwindungssteifigkeit der Abdeckplatten und tragen im übrigen zu einer Verbesserung der Rutschfestigkeit bei. Eine derartige Ausführungsform ist insbesondere als Bodenbelag für Fabrikationshallen geeignet. Für viele Anwendungsfälle ist es auch vorteilhaft, wenn nach einer weiteren bevorzugten Ausführungsform der Erfindung die Abdeckplatten eine rutschfeste Lauffläche aus Kunststoff oder Gummi aufweisen. Zur Herstellung derartiger Beschichtungen können gegebenenfalls auch Gummiabfälle, beispielsweise aus Shredderanlagen, verwendet werden.If the floor covering is to absorb high forces, it is also advantageous if the cover plates have projecting reinforcing beads on the top. Such reinforcing beads increase the torsional rigidity of the cover plates and also contribute to an improvement in the slip resistance. Such an embodiment is particularly suitable as a floor covering for manufacturing halls. For many applications it is also advantageous if, according to a further preferred embodiment of the invention, the cover plates have a non-slip tread made of plastic or rubber. Rubber wastes, for example from shredder systems, can optionally also be used to produce such coatings.

Der erfindungsgemäße Bodenbelag ist für sämtliche Freiflächen und Hallenböden geeignet, ebenso für Auffahrten, Zufahrten, Abstellplätze und Parkplätze. Der erfindungsgemäße Bodenbelag kann große Beanspruchungen aufnehmen. Er zeichnet sich aus durch eine gute Haftung zwischen den metallischen Abdeckplatten und dem Unterbau. Ferner sind die Abdeckplatten sicher gegeneinander verzahnt.The floor covering according to the invention is suitable for all open spaces and hall floors, as well as for driveways, driveways, parking spaces and parking spaces. The floor covering according to the invention can absorb large loads. It is characterized by good adhesion between the metallic cover plates and the substructure. Furthermore, the cover plates are securely interlocked.

In the following, the invention is explained in detail with reference to a drawing that shows only one exemplary embodiment. They show a schematic representation

Der in den Figuren dargestellte Bodenbelag ist insbesondere für Freiflächen und Hallenböden bestimmt. Freiflächen meint dabei auch Auffahrten, Zufahrten, Abstellplätze und Parkplätze. Der Bodenbelag weist einen Unterbau 1 aus einem aushärtbaren oder abbindefähigen Material sowie metallische Abdeckplatten 2 auf. Der Unterbau 1 besteht vorzugsweise aus Teermakadam oder Beton. Einer vergleichenden Betrachtung der Figuren 1 und 2 entnimmt man, daß die Abdeckplatten 2 umfangsseitig angeformte Verankerungselemente 3 aufweisen, die zahnförmig ineinandergreifen und unter einem spitzen Winkel α nach unten abgekantet sowie in dem ausgehärteten oder abgebundenen Unterbau 1 verankert sind. Der Winkel α, unter dem die Verankerungselemente 3 abgekantet sind, liegt zweckmäßigerweise im Bereich zwischen 30° und 60°. Vorzugsweise beträgt der Winkel α 45°. Bei der in Figur 2 dargestellten bevorzugten Ausführungsform weist der Unterbau 1 eine gitterförmige Einlage 4 aus Streckmetall auf. Man erkennt, daß die Verankerungselemente 3 dabei in die Gittermaschen der Einlage 4 eingreifen. Die gitterförmige Einlage 4 aus Streckmetall verbessert die Belastbarkeit des Bodenbelages. Eine weitere Verbesserung, insbesondere eine größere Verwindungssteifigkeit, ist noch erreichbar, wenn die Einlage 4 und die Abdeckplatten 2 durch Punktverschweißung miteinander verbunden sind. Der Figur 2 entnimmt man ferner, daß die Abdeckplatten 2 oberseitig vorspringende Verstärkungssicken 5 aufweisen. Die Verstärkungssicken 5 haben zwei Funktionen. Durch die Verstärkungssicken 5 wird die Biegesteifigkeit der Abdeckplatten 2 verbessert. Ferner führen die in großer Zahl, dicht an dicht angeordneten vorzugsweise noppenförmig ausgebildeten Verstärkungssicken 5 zu einer Verbesserung der Rutschfestigkeit des Bodenbelages. Dies ist vor allem für Bodenbeläge in Fabrikhallen von Wichtigkeit. Für viele Anwendungsfälle kann es auch zweckmäßig sein, die Abdeckplatten 2 mit einer rutschfesten Lauffläche aus Kunststoff oder Gummi zu versehen.The floor covering shown in the figures is intended in particular for open spaces and hall floors. Open space also means driveways, driveways, parking spaces and parking spaces. The floor covering has a substructure 1 made of a hardenable or setable material as well as metallic cover plates 2. The substructure 1 is preferably made of tar macaque or concrete. A comparative view of Figures 1 and 2 reveals that the cover plates 2 have anchoring elements 3 formed on the circumference, which engage in a tooth-like manner and are bent downwards at an acute angle α and are anchored in the hardened or set substructure 1. The angle α, at which the anchoring elements 3 are folded, is expediently in the range between 30 ° and 60 °. The angle α is preferably 45 °. In the preferred shown in Figure 2 In one embodiment, the substructure 1 has a lattice-shaped insert 4 made of expanded metal. It can be seen that the anchoring elements 3 engage in the mesh of the insert 4. The grid-shaped insert 4 made of expanded metal improves the resilience of the floor covering. A further improvement, in particular greater torsional rigidity, can still be achieved if the insert 4 and the cover plates 2 are connected to one another by spot welding. It can also be seen from FIG. 2 that the cover plates 2 have reinforcing beads 5 projecting on the upper side. The reinforcing beads 5 have two functions. The bending stiffness of the cover plates 2 is improved by the reinforcing beads 5. Furthermore, the large number of reinforcing beads 5, which are arranged close to one another and are preferably knob-shaped, lead to an improvement in the slip resistance of the floor covering. This is particularly important for floor coverings in factory halls. For many applications, it may also be appropriate to provide the cover plates 2 with a non-slip tread made of plastic or rubber.

Im Ausführungsbeispiel sind die Verankerungselemente 3 als Laschen mit rechteckiger Gestalt ausgebildet. Sie sind in gleichen Abständen s zueinander regelmäßig am Umfang der Abdeckplatten 2 angeordnet. Der Figur 1 entnimmt man, daß jeweils eine Lücke 6 zwischen den Verankerungselementen mit einem Verankerungselement 3' an der gegenüberliegenden Seitenkante korrespondiert. Im Ausführungsbeispiel sind die Abdeckplatten 2 quadratisch und weisen an jeder Seitenkante zwei laschenförmige Verankerungselemente 3 auf.In the exemplary embodiment, the anchoring elements 3 are designed as tabs with a rectangular shape. They are regularly arranged at the same distance s from one another on the circumference of the cover plates 2. It can be seen from FIG. 1 that in each case a gap 6 between the anchoring elements corresponds to an anchoring element 3 'on the opposite side edge. In the exemplary embodiment, the cover plates 2 are square and have two tab-shaped anchoring elements 3 on each side edge.

Die Verlegung des Bodenbelages ist auf einfache Weise möglich. Zunächst wird der Unterbau 1, vorzugsweise aus Teermakadam oder Beton, hergestellt. Bevor der Unterbau ausgehärtet oder abgebunden ist, wird die Einlage 4 aus Streckmetall aufgelegt und die Abdeckplatten 2 darüber angeordnet. Gegebenenfalls werden bei der Verlegung die Abdeckplatten 2 mit der Einlage 4 punktverschweißt. Bei der Verlegung ist darauf zu achten, daß die Gittermaschen der Einlage 4 und die Abdeckplatten 2 parallel zueinander ausgerichtet sind. Bevor der Unterbau 1 ausgehärtet oder abgebunden ist, wird die Auflage, bestehend aus der Streckmetalleinlage 4 und den Abdeckplatten 2, festgewalzt. Nach Aushärtung bzw. vollständiger Abbindung des Unterbaus 1 sind die Einlage 4 sowie die Abdeckplatten 2 durch die nach unten abgekanteten Verankerungselemente 3 in dem Unterbau 1 fest verankert. Der Bodenbelag ist nunmehr befahrbar. Der fertigverlegte Bodenbelag kann schließlich noch durch öl- oder säurebeständige Beschichtung versiegelt werden.It is easy to lay the floor covering. First, the substructure 1 is preferably made of Tar macaque or concrete. Before the substructure has hardened or set, the insert 4 made of expanded metal is placed on top and the cover plates 2 are arranged above it. If necessary, the cover plates 2 are spot welded to the insert 4 during installation. When laying, make sure that the mesh of the insert 4 and the cover plates 2 are aligned parallel to each other. Before the substructure 1 has hardened or set, the support, consisting of the expanded metal insert 4 and the cover plates 2, is rolled down. After the substructure 1 has hardened or completely set, the insert 4 and the cover plates 2 are firmly anchored in the substructure 1 by the anchoring elements 3 which are bent downward. The floor covering can now be driven on. The finished floor covering can finally be sealed with an oil or acid resistant coating.
