Abstract
Es wird eine Doppelbodenkonstruktion, bestehend aus in vorgegebenen Abständen auf einer tragfähigen Unterkonstruktion aufgestellten Stützen und aus auf diesen Stützen direkt oder indirekt aufgelagerten plattenartigen Bodenelementen, die jeweils durch einen Verbund mehrerer übereinander gelagerter Schichten unterschiedlicher Werkstoffe gebildet sind, vorgeschlagen bei der der Verbund aus einer aus keramischen Material bestehenden Deckplatte, einer aus biegesteifem Material geringen Raumgewichts bestehenden Kernschicht und einer dünnen Unterschicht mit hohen Zugfestigkeitseigenschaften zusammengesetzt ist. Mit dieser Doppelbodenkonstruktion wird die Aufgabe gelöst, daß die einzelnen plattenartigen Bodenelemente hinsichtlich ihrer Abmessungen, insbesondere ihrer Dickenabmessungen optimal gewählt werden können und trotzdem die Aufnahme hoher Traglasten möglich ist. Außerdem wird noch erreicht, daß die Beständigkeit der Oberflächen gegen organische Lösungsmittel und andere Chemikalien gegeben ist. Schließlich benötigen die Bodenbeläge zu ihrer Verbindung mit dem Unterboden keinen Kleber, der hinsichtlich seiner Stabilität bedenklich sein könnte.A double floor construction consisting of supports set up at predetermined intervals on a load-bearing substructure and of plate-like floor elements directly or indirectly supported on these supports, each of which is formed by a composite of several superimposed layers of different materials, is proposed, in which the composite consists of one ceramic material existing cover plate, a core layer consisting of rigid material with a low density and a thin underlayer with high tensile properties. With this double floor construction, the problem is solved that the individual plate-like floor elements can be optimally selected with regard to their dimensions, in particular their thickness dimensions, and nevertheless the absorption of high loads is possible. In addition, the surfaces are resistant to organic solvents and other chemicals. After all, the floor coverings do not need any adhesive for their connection to the subfloor, which could be questionable in terms of their stability.
Description
Die Erfindung betrifft eine Doppelbodenkonstruktion, bestehend aus in vorgegebenen Abständen auf einer tragfähigen Unterkonstruktion aufgestellten Stützen und aus auf diesen Stützen direkt oder indirekt aufgelagerten plattenartigen Bodenelementen, die jeweils durch einen Verbund mehrerer übereinander gelagerter Schichten unterschiedlicher Werkstoffe gebildet sind.The invention relates to a raised floor construction, consisting of supports placed at predetermined intervals on a load-bearing substructure and of plate-like floor elements directly or indirectly supported on these supports, each of which is formed by a combination of several layers of different materials superimposed on one another.
Einer überwiegend angewendeten Gruppe solcher Bodenelementen ist gemeinsam, daß sie aus wannenartigen Gebilden bestehen, die aus Blech oder Stahlrahmen kombiniert mit einem Blechboden hergestellt sind. Die Füllung dieser Wannen besteht aus unterschiedlichen Werkstoffen, wie Gips, Beton, Holzfaserstoffen od. dgl.. Auch die Weiterführung der Wannenummantelung um einen als Füllung dienenden Spanplattenkern findet Anwendung. Eine andere Gruppe solcher Bodenelemente besteht in Stahlrohrprofilen oder Alu-Druckgußplatten.A predominantly used group of such floor elements has in common that they consist of trough-like structures which are made of sheet metal or steel frames combined with a sheet metal base. The filling of these tubs consists of different materials, such as gypsum, concrete, wood fiber materials or the like. The continuation of the tub casing around a chipboard core serving as filling is also used. Another group of such floor elements consists of tubular steel profiles or die-cast aluminum plates.
Beide Gruppen weisen aus obersten Abschluß entweder Teppichboden- oder Hart-PVC-Beläge auf. Sämtliche auftretenden statischen Beanspruchungen müssen also von den Wannenkonstrultionen aufgenommen werden, da die Abschlußbeläge hierzu nichts beitragen können.Both groups have either carpeted or hard PVC coverings at the top. All static loads that occur must therefore be absorbed by the tub controls, since the final coverings cannot contribute to this.
In jüngerer Zeit werden aber Anforderungen an Doppelbodenkonstruktionen gestellt, bei denen bis zu 1000 kg/Element von 60 x 60 cm Abmessungen gefordert werden. Solche Anforderungen erzwingen aber eine erhebliche Vergrößerung der Dickenabmessungen der Elemente, die zu einer Verteuerung der gesamten Konstruktion und Sohierigkeiten bei der Geschoßhöhenbemessung führen können. Außerdem werden solche Elemente dann selbstverständlich erheblich schwerer, was sich auf die Dimensionierung der tragfähigen Unterkonstruktion nachteilig auswirkt.More recently, however, demands have been placed on raised floor constructions, in which up to 1000 kg / element of 60 x 60 cm dimensions are required. However, such requirements force a considerable increase in the thickness dimensions of the elements, which lead to a ver expensive of the entire construction and problems with the floor height can lead. In addition, such elements will of course become considerably heavier, which has a disadvantageous effect on the dimensioning of the load-bearing substructure.
Die Erfindung hat sich die Aufgabe gestellt, eine Doppelbodenkonstruktion zu entwickeln, bei der die einzelnen plattenartigen Bodenelemente hinsichtlich ihrer Abmes- sungen insbesondere ihrer Dickenabmessungen optimal gewählt werden können und trotzdem die Aufnahme hoher Traglasten möglich ist. Außerdem sollte Beständigkeit der Oberfläche gegen organische Lösungsmittel und andere Chemikalien gegeben sein und schließlich sollen die Bodenbeläge zu ihrer Verbindung mit dem Unterboden keine Kleber benötigen, die hinsichtlich ihrer Stabilität bedenklich sind.The invention has the task of developing a double bottom construction in which the individual plate-like floor elements solutions regarding their A bmes- particular their thickness dimensions can be optimally selected while supporting high loads is possible. In addition, the surface should be resistant to organic solvents and other chemicals and, finally, the floor coverings should not require any adhesives for their connection to the sub-floor, which are questionable in terms of their stability.
Diese der Erfindung zugrunde liegende Aufgabe wird dadurch gelöst, daß der Verbund aus einer aus keramischem Material bestehenden Deckplatte, einer aus biegesteifem Material geringen Raumgewichtes bestehenden Kernschicht und einer dünnen Unterschicht mit hohen Zugfestigkeitseigenschaften zusammengesetzt ist. Man erreicht mit einer solchen Konstruktion eine erhebliche Gewichtsreduzierung gegenüber den bekannten Konstruktionen, eine erheblich höhere statische Festigkeit, eine Höheneinsparung der Bodenkonstruktion bei gleichem Zwischenraum oder bei gleicher Höhe einen grösseren Zwischenraum. Außerdem ist kein metallisches Element vorhanden, das gegebenenfalls korrodieren könnte.This object on which the invention is based is achieved in that the composite is composed of a cover plate consisting of ceramic material, a core layer consisting of rigid material having a low density and a thin underlayer with high tensile properties. With such a construction, a considerable weight reduction compared to the known constructions, a considerably higher static strength, a height saving of the floor construction with the same space or with the same height, a larger space are achieved. In addition, there is no metallic element that could possibly corrode.
Vorzugsweise sind die verschiedenen Schichten des Verbundes unter Verwendung eines Klebers, gegebenenfalls unter Druckeinwirkung miteinander verbunden. Besonders zweckmäßig ist es, wenn die Deckplatte aus einer aus plastischem, keramischen Ausgangsmaterial gepreßten, gewalzten und gebrannten Platte hoher Druckfestigkeit besteht, deren Dicke im Verhältnis zur Oberfläche 1:45000 bei einer flächenmäßigen Erstrekkung der Platte annähernd 30 x 30 cm beträgt.The various layers of the composite are preferably connected to one another using an adhesive, if appropriate under the action of pressure. It is particularly expedient if the cover plate consists of a pressed, rolled and fired plate made of plastic, ceramic starting material, the thickness of which in relation to the surface is 1: 45000 with an areal extension of the plate approximately 30 x 30 cm.
Als Kernschicht verwendet man vorteilhaft ein hochporöses Material oder ein wabenartiges Material, wobei im letzteren Fall die Wabenachsen senkrecht zur Deckplatte anzuordnen sind. Auch bei der Kernschicht kann es sich an sich um keramisches Material handeln, das ohne Schwierigkeiten zu einem hochporösen Formkörper oder zu einem Wabenkörper verarbeitbar ist. Die Unterschicht besteht vorzugsweise aus einem Glas-, Mineral-, Kohle- oder Kunststoff-Fasergewebe oder -vlies. Bei Verwendung von keramischem Material für die Kernschicht und/oder Glas-, Mineral- oder Kohlefasern als Material für die Unterschicht erfolgt die Verbindung zweckmäßig durch ein glasurartiges Material, dessen Schmelzpunkt unterhalb des Quarzumwandlungspunktes (573°C) liegt. Die Zeichnung zeigt in einer einzigen Figur einen Schnitt durch ein Bodenelement, wie es zum Aufbau der erfindungsgemäßen Doppelbodenkonstruktion Verwendung finden kann.A highly porous material or a honeycomb-like material is advantageously used as the core layer, in which case the honeycomb axes are to be arranged perpendicular to the cover plate. The core layer can also be a ceramic material per se, which can be processed without difficulty into a highly porous molded body or into a honeycomb body. The lower layer preferably consists of a glass, mineral, carbon or plastic fiber fabric or fleece. When using ceramic material for the core layer and / or glass, mineral or carbon fibers as the material for the underlayer, the connection is expediently made by a glaze-like material whose melting point is below the quartz transformation point (573 ° C.). In a single figure, the drawing shows a section through a floor element, as can be used to construct the raised floor construction according to the invention.
Mit 1 ist dabei allgemein der Verbund bezeichnet, der aus einer aus keramischem Material bestehenden Deckplatte 2, einer aus biegesteifem Material geringen Raumgewichtes bestehenden Kernschicht 3 und einer dünnen Unterschicht 4 mit hohen Zugfestigkeitseigenschaften zusammengesetzt ist.1 generally denotes the composite, which is composed of a
Bei dem gewählten Ausführungsbeispiel besteht die Kernschicht aus einem keramischen Wabenkörper, dessen Wabendurchbrüche mit 5 bezeichnet sind.In the selected embodiment, the core layer consists of a ceramic honeycomb body, the honeycomb breakthroughs are designated 5.
