  • the molding box can be used to form the edge sections (folds) for example with vertically movable sliders be trained. With the help of these sliders can Pour the matrix material into the molding box Defined edge zones are kept free of backing material so that the (tapered) edge sections in these zones the building board is molded in one operation (manufactured) to make a total of to get monolithic plate.
  • the matrix material is in one embodiment from a tied hydraulic and / or latent hydraulic binders (the latter always together with a usual stimulator).
  • the offset may additionally contain fibers, so that the matrix of the set plate at least in sections with fibers is reinforced, which increases the strength of the building board can be increased in sections or in total.
  • the Fiber reinforcement can be applied to the lower and / or area upper cover layer (main surface) of the building board be limited; alternatively, the fibers can be homogeneous in the entire building board body.
  • the fibers can be from at least one of the following groups consist of: alkali-stabilized glass fibers, polyacrylonitrile fibers, Carbon fibers, polyester fibers, polyamide fibers, Polypropylene fibers, paper fibers, animal Natural fibers, vegetable natural fibers, ceramic fibers.
  • Recycled fibers can for example fibers from carpets or Be waste paper fibers.
  • the fiber length depends on the specific application. As a rule, the Fiber length for plastic fibers ⁇ 12 mm and for paper fibers ⁇ 5 mm.
  • the fiber content, based on the Total mass (the offset) can be between 0.5 and 15 Mass% fluctuate.
  • the matrix can be one Contain aggregate, for example a lightweight aggregate, for example a substance from the group: expanded pearlite, expanded vermiculite, foam glass, Pumice, expanded clay, expanded slate, lava. Processing a such offset can be done so that the light supplement also not destroyed during the pressing process becomes. In this way, a plate with good Establish thermal insulation.
  • the aggregate can but also be sand, slag or the like. The Aggregate can be used to increase weight accordingly or serve weight reduction.
  • An exemplary offset from which the matrix is formed can be comprised, 50 to 80 mass% at least one hydraulic, latent hydraulic or pozzolana Binder, 0.5 to 15% by mass of fibers and 5 to 45 Mass% aggregates.
  • the offset can also contain other components, for example liquid or solid substances for hydrophobing the building board, for example silanes, silicones, Waxes, oleates, stearates, individually or in combination.
  • Chemical additives can also be used, which delay or accelerate the hydraulic reaction or reduce the water requirement. Further Chemical additives like starch can offset be mixed in, for example, the springback of the to reduce the molded part after the pressing process.
  • the building board can with a fabric insert in at least be formed on a main surface.
  • a fabric insert can be made in the molding box during manufacture submitted or placed on the bulk material are, if necessary after a first pressing process and before a second pressing process.
  • Such a fabric insert can consist of at least one Fabrics of the following groups exist: plastic-coated Glass fiber fabrics, carbon fiber fabrics, ceramic Fabrics, fabrics made from animal or vegetable fibers.
  • the edge sections of the plate can with a wedge to trapezoidal profile are formed.
  • a sloping setting surface becomes the putting on / sliding on an adjacent plate (with its inverse shaped edge sections) optimized during installation.
  • This embodiment creates the possibility that the Core of the plate subsequent folding section in a Form thickness greater than half of the total plate is. This gives the fold increased stability, especially bending tensile strength.
  • edge reinforcement can be a modified press device can be done by clicking on the mentioned last is dispensed with.
  • offset the matrix material
  • the marginal areas accordingly have a higher density than the core of the Plate on, core except the entire plate the fold-like edge areas means.
  • the specific edge formation of the plate looks an embodiment that the edge sections, starting from the one with the corresponding main surface aligned base a first, substantially perpendicular have an outer edge running to the base, to which the seating area connects and from which a butt edge runs to the other main surface.
  • the transition from adjacent surface sections can be rounded to avoid a notch effect.
  • the corner area between inversely arranged edge sections be cut out.
  • Adjacent edge sections with aligned base areas can be in the corner / connection area at an angle of 45 ° to the respective outer edge merge.
  • the butt edge can be at an angle> 90 ° to corresponding main surface, whereby Notch effects can be prevented.
  • Both the butt edge and the outer edge can be one Have height, each less than half the thickness the building board is. This makes it possible to use the seating area to form an appealing inclination, which means that it is postponed adjacent slabs easier when laying becomes.
  • a top layer can, for example, exclusively from hydraulic and / or pozzolanic (e.g. an ash from Fluidized bed furnaces) and / or latent hydraulic Binders (for example, blastfurnace slag) exist.
