Abstract:
A composite floor covering structure with a mortar layer (8, 17, 19) set by a mineral agent and a carrier plate (4, 14, 22) adjoining the lower surface of the mortar layer (8, 17, 19), said carrier plate substantially consisting of a flat base element (5, 16) and upwardly projecting structural elements (6, 15, 23, 24) projecting into the mortar (8, 17, 19) and substantially having the same height, whereby the mortar covering (U) above the projecting structural elements (6, 15, 23, 24) is dimensioned in such a way that the negative structures formed by the structural elements (6, 15, 23, 24) in the mortar (8, 17, 19) represent predefined fracture zones (20, 21) for reducing occurring stresses, characterized in that the structural elements (6, 15, 23, 24) are spaced from each other and arranged according to a regular pattern with respect to the base element (5, 16) and molded on said element, said structural elements (6, 15, 23, 24) forming in the mortar layer (8, 17, 19) negative structures acting like a perforation, so that when stresses develop in the mortar layer (8, 17, 19), the negative structures are starting points for joint face assemblies (10, 11, 20, 21) spreading between said negative structures.
