  • connecting elements are prefabricated separately, which is relatively complex.
  • the EP 2 405 065 B1 The state of the art shown has the same load deformation behavior of the connecting elements, which means that deformation and force transmission are not decoupled from each other. This could result in an uneven distribution of forces along the building wall and possibly an uneven expansion of the cast building wall in its longitudinal direction.
  • the present invention is therefore based on the object of addressing at least one of the above-mentioned problems.

  • the transferable shear forces are determined by the shear stresses in the connection area between the precast brick and the building wall or the floor or ceiling slab, which are greater than 0.5 N/mm 2 in relation to the wall base area. For example, for a 20 cm thick wall and a precast brick of the same width, the calculation 0.5 N/mm 2 * 1000 mm * 200 mm results in a shear force of 100 kN/m.
