  • the extension 50 can come to rest in one of the receptacle widenings 83, 85. By protruding the extension 50 into the receptacle 82 of the underlying second brick 100, a positive connection between the first brick 10 and the second brick 100 can be provided.
  • first brick 10 experiences a movement perpendicular to the plane of the wall 1 due to external influences, it can be stabilized by the extension 50 which comes to rest on an edge of the receptacle 82.
  • a corresponding wall can withstand a much higher level of mechanical loads of a thermal or seismic type.
  • a plurality of first and second bricks 10, 100 bricked up in layers lying one above the other can contribute to the formation of a wall between beams 96 of a building.
  • a wall pane which is structurally stabilized according to the present invention or a corresponding brick lining
  • the proportion of bricks that are designed either with anchoring or with a receptacle for an extension should be at least 5% of the wall area be.
  • Preferably 6 to 8% of the wall area is formed by first or second masonry stones in the sense of the present disclosure.
  • first and the second bricks are given a freely selectable coloring by using appropriate additives in the casting compound.
  • the bricks 10, 100 provided here and equipped with an anchoring 20 or with a receptacle 82 and formed from a hardenable casting compound can be color-matched to other, conventional bricks 200.
  • the first and / or the second bricks in the sense of the present disclosure are provided with different textures or surfaces.
  • the textures and surface can be created by using appropriate matrices in a formwork to form the bodies 12, 112.
  • the bodies 12, 112 of the bricks 10, 100 formed by a hardenable casting compound can thus also be adapted to the other bricks 200 of a wall 1 with regard to their outer contour and texture.
