Description

Aus Schaumkeramik bestehender Baukörper und Verfahren zu seiner Herstellung.Structure made of foam ceramics and process for its manufacture.

Die Erfindung betrifft einen aus Schaumkeramik bestehenden Baukörper, vorzugsweise in Form einer großformatigen Bauplatte, und richtet sich ferner auf ein Verfahren zur Herstellung eines solchen Baukörpers.The invention relates to a structure consisting of foam ceramic, preferably in the form of a large-format building board, and also straightens up a method for producing such a structure.

Aus Schaumkeramik bestehende Baukörper bieten sich insbesondere wegen ihres vergleichsweise geringen Gewichtes an. Sie weisen jedoch den Nachteil auf, daß sie eine nur geringe Schlagfestigkeit besitzen. Sie müssen infolgedessen im allgemeinen durch Uusätzliche Maßnahmen an den Außenflächen geschützt werden. Das Aufbringen von Materialien anderer Art als Keramik oder das Abdecken durch Verkleidungselemente erfordert grundsätzlich wenigstens zusatzliche Arbeitsgänge und verteuert damit die Herstellung des entsprechenden Bauelementes.Structures made of foam ceramics are particularly useful because of their comparatively low weight. However, they have the disadvantage that they have only a low impact resistance. As a result, you have to im generally be protected by additional measures on the external surfaces. That Application of materials other than ceramic or covering with cladding elements basically requires at least additional work steps and thus makes it more expensive the production of the corresponding component.

Aufgabe der Erfindung ist die Schaffung eines aus Schaumkeramik bestehenden Baukörpers, der vollständig aus keramischem Material besteht, jedoch so ausgebildet ist, daß die Schlagfestigkeit des Baukörpers gegenüber schaumkeramischen Baukörpern erheblich verbessert ist.The object of the invention is to create a foam ceramic Structure made entirely of ceramic Material exists, however is designed so that the impact resistance of the structure compared to foam ceramic Structures is significantly improved.

Außerdem soll durch die Erfindung ein aus Schauinkeramik bestehender Baukörper geschaffen werden, der keinerlei weiterer Nachbearbeitung und im allgemeinen auf keinerlei weiterer Beschichtung bedarf, es sei denn die entsprechende Wandfläche stellt eine Innenwand dar, bei der man es vorzieht, einen Anstrich oder eine Tapezierung vorzusehen.In addition, the invention is intended to provide a display ceramic Buildings are created that do not require any further post-processing and in general no further coating is required, unless the corresponding wall surface represents an interior wall that is preferred to be painted or wallpapered to be provided.

Die der Erfindung zugrunde liegende Aufgabe wird bei einem aus Schaumkeramik bestehenden EiiausWrper, vorzugsweise in Form einer großformatigen Bauplatte e7;zst durch einen wenigstens einseitig mit normaler Keramik beschichteten Schalmkeramik körper.The object on which the invention is based is achieved in the case of a foam ceramic existing egg body, preferably in the form of a large-format building panel e7; zst by a scarf ceramic coated at least on one side with normal ceramic body.

Vorzugsweise ist der Schaumkeramikkörper beidseitig mit normaler Keramik beschichtet.The foam ceramic body is preferably made of normal ceramic on both sides coated.

Das erfindungsgemäße Verfahren zur Herstellung eines solchen Baukörpers ist dadurch gekennzeichnet, daß auf eine beliebig dicke Schicht normaler Keramik eine beliebig dicke Schicht aus einer schäumbaren Keramikmasse aufgetragen und diese Schicht gegebenenfalls mit einer beliebig dicken Schicht aus normaler Keramik abgedeckt wird, worauf dieser Verbundkörper bei einer Schäume und Brenntemperatur gebrannt wird, bei welcher die Mistelscnicht aufschäumt und sich zusammen mit den Außenschichten verfestigt.The method according to the invention for producing such a structure is characterized in that on an arbitrarily thick layer of normal ceramic an arbitrarily thick layer of a foamable ceramic mass is applied and this Layer optionally covered with a layer of normal ceramic of any thickness whereupon this composite body is fired at a foaming and firing temperature in which the mistletoe does not foam and melts together with the outer layers solidified.

Vorzugsweise wird das Verfahren so geführt, daß die einzelnen Schichten im Zuge ihrer Herstellung auf ihren späteren Eontaktflächen mit aufeinander abgestimmten schwalbenschwanzförmigen Querschnitt aufweisenden Verankerungsvor- bzw. -rucksprungen versehen werden. Beim Zusammenlegen der verschiedenen Schichten aus normaler Keramik und Schaunkeramik verzahnen sich diese Vor- bzw. Rücksprünge, wodurch die gegenseitige Haftung der Schichten erheblich verbessert werden kann.The method is preferably carried out in such a way that the individual layers in the course of their production on their later contact surfaces with coordinated Anchoring projections or anchoring protrusions with dovetail-shaped cross-section be provided. When putting the different layers of normal ceramic together and Schaunkeramik interlock these projections and recesses, whereby the mutual Adhesion of the layers can be improved considerably.

Gegebenenfalls kann in weiterer Ausbildung der Erfindung auf einer unteren Schicht aus normaler Keramikmasse die Schaumkeramikmasse in parallel zueinander verlaufenden, einen Abstand aufweisenden Strängen ausgelegt werden. Bei einem derart gestalteten Verbundkörper befinden sich also zwischen den beiden Deckschichten aus normaler keramischer Masse parallel zueinanderverlaufende Stege. Erhitzt man einen solchen Körper auf die Schäum- und Verfestigungstemperatur, dann füllt die Schaumkeramikmasse die vorhandenen Zwischenräume zwischen den Stegen aus.Optionally, in a further embodiment of the invention on a lower layer of normal ceramic mass the foam ceramic mass in parallel to each other running, spaced strands are laid out. With one like that designed composite bodies are therefore located between the two cover layers normal ceramic mass webs running parallel to each other. If you heat one up such body to the foaming and solidification temperature, then fills the foam ceramic mass the existing gaps between the webs.

In weiterer Ausbildung der Erfindung wird die über der Schaumkeramikmasse verlegte Deckschicht aus normaler keramischer es Masse breiter als die unterste Schicht ausgelegt und werden ihre überstehenden Ränder nach unten auf die Kanten der.In a further embodiment of the invention, the above the foam ceramic mass laid top layer of normal ceramic es mass wider than the bottom Layer laid out and be their protruding edges down onto the edges the.

untersten Schicht umgebogen. Mit dieser Maßnahme ist es möglich, die Schaumkeramikmasse in die Zwischenräume zwischen die Stege zu bringen, ohne daß sich die Außenabmessungen des derart fertiggestellten Körpers beim Brennen verändern. Damit können schon beim Pressen die späteren Fertigmaße voll berück sichtigt werden.bottom layer bent over. With this measure it is possible to reduce the Bring foam ceramic mass into the spaces between the webs without the outer dimensions of the finished body in this way change during firing. This means that the finished dimensions can be fully taken into account during the pressing process.

Eine Variante dazu besteht darin, die unterste Schicht aus normaler Keramik trogförmig auszulegen und die Trogränder mit der obersten Deckschicht zu verbinden.A variation on this is to make the bottom layer out of normal Lay ceramic trough-shaped and close the trough edges with the top layer associate.

Vorzugsweise wird die Herstellung des Verbundkörpers so durchgeführt, daß unter Verwendung zweier Strangpressen in der einen die Schaumkeramikmasse und in der anderen die Normalkeramikmasse geführt werden und letztere vor Erreichen des Mundstückaustrittes in zwei Massenstränge zerlegt wird, zwischen die der Schaumkeramikstrang eingeschoben wird.The production of the composite body is preferably carried out in such a way that that using two extrusions in one the foam ceramic mass and in the other the normal ceramic mass are guided and the latter before reaching of the mouthpiece outlet is broken down into two mass strands, between which the foam ceramic strand is inserted.

Brennt man die durch Zertrennen des endlosen Stranges entstandenen Abschnitte liegend beispielsweise in einem Tunnelofen auf einem Brennwagen,so ist es möglich, die von der Brennwagenfläche abgelegene Seite mit einer Glasur, oder einer sonstigen Dekorschicht zu versehen. Beim stehenden Brennen läßt sich eine solche Dekorschicht auf beiden Flächen des Verbundkörpers vorsehen. Im allgemeinen genügen jedoch die nach dem Brennen des Baukörpers entstandenen Außenflächen allen Anforderungen, S daß eine weitere Nachbearbeitung nicht erforderlich ist und insbesondere auf eine weitere Beschichtung verzichtet werden kann. Lediglich für den Fall, daß die eine Wandfläche des Baukörpers die Innenwand beispielsweise eines Gebäudes darstellt, kann gewünschtenfalls ein Anstrich vorgenommen oder eine Tapete aufgebracht werden.If you fire the ones created by cutting the endless strand Sections lying in a tunnel kiln on a kiln car, for example it is possible to apply a glaze, or one other decorative layer to be provided. When burning such a decorative layer can be provided on both surfaces of the composite body. In general, however, the outer surfaces created after the building was fired are sufficient all requirements, S that further post-processing is not necessary and in particular, a further coating can be dispensed with. Only for the case that one wall surface of the structure is the inner wall, for example one The building can, if desired, be painted or wallpapered be applied.

Die Zeichnungen zeigen in Fig. 1 einen Baukörper gemäß der Erfindung; Fig. 2 einen Vorformling für die Herstellung eines Baukörpers gemäß der Erfindung, bei dem bereits beim Pressen die späteren Fertigmaße voll berücksichtigt werden können; Fig. 3 eine weitere Ausführungsform eines Baukörpers gemäß der Erfindung.The drawings show in Fig. 1 a structure according to the invention; 2 shows a preform for the production of a structural body according to the invention, in which the later finished dimensions are fully taken into account during the pressing can; 3 shows a further embodiment of a structure according to the invention.

In Fig. 1 ist mit 1 eine aufgeschäumte Keramikschicht bezeichnet, die durch die obere Deckschicht 2 und die untere Deckschicht 3 begrenzt wird.In Fig. 1, 1 denotes a foamed ceramic layer, which is delimited by the upper cover layer 2 and the lower cover layer 3.

Bei dem Ausführungsbeispiel nach teig. 2 ist die untere Deckschicht 4 trogförmig ausgebildet. Der Trog ist mit Stegen 5 aus schäumbarer keramischen Masse besetzt und durch die Deckschicht 6 abgedeckt. Bei der Führung dieses Vorformlings durch den Brennofen, beispielsweise auf der Plattform eines Brennwagens, der einen Tunnelofen durchfährt, schäumt die keramische Masse, aus denen die Stege 5 hergestellt sind, in die freien zwischen den Stegen verbliebenen Räume 7, so daß diese Räume, wenn das Produkt den Ofen verläßt' mit schaumiger Keramikmasse vollgeschäumt sind.In the embodiment after dough. 2 is the lower cover layer 4 trough-shaped. The trough is made of foamable ceramic with webs 5 Mass occupied and covered by the cover layer 6. When guiding this preform through the kiln, for example on the platform of a kiln car, the one Passes through the tunnel furnace, the ceramic mass from which the webs 5 are made foams are, in the free spaces 7 remaining between the webs, so that these spaces, when the product leaves the oven are fully foamed with foamy ceramic mass.

In Fig. 3 ist ein Ausführungsbeispiel wiedergegeben, bei dem die beiden Deckschichten 8 und 9, zwischen denen die aus Schaumkeramik bestehende Mittelschicht eingeschlossen ist, mit schwalbenschwanzförmigen Vorsprüngen 11 versehen sind, denen entsprechende Rücksprünge in der Schaumkeramikmasse 10 entsprechen. Die bessere Verankerung ist ohne Schwierigkeiten zu erkennen.In Fig. 3, an embodiment is shown in which the two Cover layers 8 and 9, between which the foam ceramic middle layer is included, are provided with dovetail-shaped projections 11, which corresponding recesses in the ceramic foam mass 10 correspond. The better one Anchoring can be seen without difficulty.
