<p>PCT No. PCT/DE97/00102 Sec. 371 Date Jul. 24, 1998 Sec. 102(e) Date Jul. 24, 1998 PCT Filed Jan. 15, 1997 PCT Pub. No. WO97/30247 PCT Pub. Date Aug. 21, 1997A composite floor structure comprises a mortar layer set by a mineral agent and a carrier plate adjoining the lower surface of the mortar layer. The carrier plate has upwardly projecting structural members extending into the mortar. The dimensions of the mortar coating over the structural members are so low that the structures created in the mortar by the structural members represent weak areas. When stresses arise in the mortar layer, joint face assemblies connecting weak areas are formed to reduce stress in a uniform manner. By forming different joint face assemblies, a joint face structure is produced, wherein to reduce stress, the stress causing the mortar to fracture only results in a low level of longitudinal change in each individual joint face. Consequently, each individual joint face only takes the form of a microcrack.</p> |
