  • Grooves encircling the face of the stove tile enable a tile structure of high stability to be built up quickly by means of so-called gussets inserted into the grooves as connecting elements, the grooves being filled with clay mortar.
  • a disadvantage of such stove tiles is the edge formation in a tile structure and the insufficient stability in stove ceilings formed with such stove tiles and in the area of an operating opening.
  • a plate-like element for producing the outer structure of a tiled stove or a fireplace is also known, in which at least a portion of each of the peripheral edge regions has a shape for receiving detachable connecting links, these receptacles also being formed by pocket-shaped grooves which are formed at least in one section or grooves extending over the entire length of the end faces. Connectors with a press fit can be inserted into these grooves, thus achieving a high resistance to wall dressings.

  • the taper of the recesses also simplifies a molding process of the building blocks, be it in the casting process or a dry pressing process, and a complicated structure of molds and tools is avoided.
  • the formation of the recesses is designed so that excess connecting means introduced into the recesses, e.g. Glue, mortar, etc., can be pressed out when inserting the connecting elements to produce a positive fit.
  • Formations according to claims 12 to 15 are also advantageous because they are high Strength of the building blocks is achieved and cracking or destruction of the building blocks under the high temperature load to which these building blocks are exposed is avoided.
