  • the invention proposes to form a clay building panel having a cell structure with a multiplicity of cells arranged next to one another, wherein the cells are constructed in such a way that the cell walls extend at least in the thickness direction of the clay building panel. Due to the three-dimensional cell structure, which can be designed in particular as a honeycomb structure, the clay building board is given good mechanical stability and strength, and at the same time it is achieved that the shrinkage of the clay building material is limited to the local areas of the cells during drying, so that problems arise to avoid major global shrinkage. Accordingly, it is also possible to use compositions of clay building materials which otherwise can not be used due to the shrinkage problem.
  • the cells of the cell structure may be provided in the form of tubes extending along the thickness direction of the clay building panel, the cells being open at their ends, i. that on the main surfaces of the clay building board, which are spanned by the length and the width, no cell wall of the cell structure is present, but is present in the cells filled clay building material.
  • the cells of the cell structure may also be formed as cups, in which one end of the cells is closed in the thickness direction, so that the cell structure forms a major surface of the Lehmbauplatte.

Combinations of these materials are conceivable. Particularly advantageous are cell structures that are formed from natural fibers such as linen, hemp, cotton, jute or bamboo and paper or cardboard or wood. With these materials, simple disposal of the clay building board after its use by composting is possible. In addition, a reuse by processing the clay building material is possible.

  • the cell structure may be formed as a self-supporting structure, which is arranged during manufacture, for example, on a flat surface, in order to then be filled with the clay building material.
  • cell structures are conceivable that are not self-supporting and must be kept in the appropriate form by an auxiliary structure when filling with clay building material.
  • the clay building material is filled during filling with some excess, which corresponds to the degree of compaction during pressing or rolling.
  • the clay building material can be used as a humid clay building material.
  • the compacting of a soil-moist clay building material has, inter alia, the advantage that immediately after compacting, a solid structure is present and after a short drying high hardness and strength is given, so that the production times are greatly reduced.
