The invention relates to a structure consisting of foam ceramic, preferably in the form of a large-format one Building board.

5 · Structures made of foam ceramics are particularly suitable because of their comparatively low weight. However, they have the disadvantage that they only have one have low impact resistance. As a result, you generally have to take additional measures to the External surfaces are protected - The application of materials other than ceramic or covering by cladding elements basically requires at least additional work steps and thus makes it more expensive the production of the corresponding component.

The object of the invention is to create a structure made of foam ceramic that completely made of ceramic material, but designed in this way

is that the impact resistance of the structure compared to foam ceramic structures is significantly improved.

In addition, the invention is intended to create a structure made of foam ceramics that does not have any Further post-processing and, in general, no further coating is required, unless the appropriate Wall surface represents an interior wall that is preferred to be painted or wallpapered to be provided.

The object on which the invention is based is preferably achieved in the case of a structure made of foam ceramic in the form of a large-format building board solved by at least one side with normal ceramic coated foam ceramic body.

The foam ceramic body is preferably coated on both sides with normal ceramic.

In an advantageous embodiment of the invention, the ceramic layers made of normal ceramic have at least on the side facing the foam ceramic part, anchoring projections or recesses with dovetail shaped cross-sections. When putting together the different layers of normal ceramic and Foam ceramics interlock these projections and recesses, which means that the layers adhere to one another can be vastly improved. It is particularly advantageous if these projections and recesses with the normal ceramic layers are in one piece.

In a further embodiment of the invention, the cover layer laid over the ceramic foam mass is made of normal

ceramic mass is laid out wider than the bottom layer and its protruding edges are after bent down onto the edges of the bottom layer. With this measure it is possible to exit to prevent the foam ceramic mass from the building, so that any reworking for There is no need to remove protruding ceramic foam.

A variant of this is to design the bottom layer of normal ceramic trough-shaped and the

To connect the trough edges with the uppermost cover layer.

A method for making one according to the invention The structure is characterized by the fact that any layer of normal ceramic can be placed on any thickness thick Schichx applied from a foamable ceramic mass and this layer if necessary with any thick layer of normal ceramic is covered, whereupon this composite body with a foaming and Firing temperature is fired at which the middle layer foams up and together with the outer layers solidified.

If necessary, it can be made on a lower layer normal ceramic mass, the foam ceramic mass running parallel to one another and having a spacing Strands are laid out. With such a designed Composite bodies are therefore located in parallel between the two cover layers made of normal ceramic material mutually extending webs. If such a body is heated to the foaming and solidification temperature, then the foam ceramic mass fills the existing spaces between the webs.

The production of the composite body is preferred carried out so 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 the mouthpiece outlet in two Mass strands is broken down, between which the foam ceramic strand is inserted.

Fig. 3 shows a further Ausführungsforra one Structure according to the invention.

In Fig. 1, 1 denotes a foamed ceramic layer, which by the upper cover layer 2 and the lower cover layer 3 is limited.

In the embodiment according to FIG. 2, the lower cover layer 4 is trough-shaped. With such a The trough is preformed with webs 5 made of foamable ceramic mass and through the Cover layer 6 covered. When guiding this preform through the kiln, for example the platform of a kiln car driving through a tunnel kiln, the ceramic mass from which it foams the webs 5 are made into the free spaces 7 remaining between the webs, so that these spaces when the product leaves the oven, they are filled with foamy ceramic mass.

In Fig. 3, an embodiment is shown in which the two cover layers 8 and 9, between which include the middle layer made of ceramic foam, with dovetail-shaped protrusions 11 are provided, to which corresponding recesses in the ceramic foam mass 10 correspond. the better anchoring can be seen without difficulty.
