Definitions

  • the invention relates to a lightweight board according to the preamble of claim 1.
  • the known lightweight board it is provided to arrange two intermediate layers in such a way that the two pyramids are directed towards one another, but are somewhat offset in the plane with respect to one another, so that the projections of the upper intermediate layer point downward and plunge into the spaces which are located between the upward projections of the lower intermediate layer.
  • a lightweight board which is capable of absorbing high shear forces and which has a high bending strength with a low weight.
  • the invention has for its object to improve a generic lightweight board in such a way that it can be produced with the cheapest possible means in almost any plate thickness.
  • the invention proposes to create an adapter plate which has pyramid-shaped projections on both sides of the plate, so that further construction into the space is possible on both sides of the plate.
  • any combination of adapter plates and the single-layer interlayer plates, which have protrusions on only one side, can achieve plate thicknesses of almost any desired value.
  • the adapter plate can be produced particularly inexpensively by connecting two of the usual interlayer plates to form the hollow double pyramids of the adapter plate. Mechanical connections, such as screw connections or rivets or the like, are fundamentally possible. However, the adapter plate can absorb particularly high forces if the two plates are connected to one another by gluing, cold welding or thermal or ultrasonic welding.
  • the designation that the projections are “hollow” means that the projections are predominantly filled with gas, for example with ambient air, since the weight of the lightweight building board can advantageously be kept low by such a gas filling.
  • the cavity can also be provided not to release completely within the ledge, but to fill it with a foam, for example, in order to achieve particularly high strength values for the lightweight board. Since such a foam or other as light as possible filling materials for the pyramid-shaped projections have a large proportion of voids, projections filled with such filling materials are also referred to as “hollow” in the sense of the present invention.
  • Particularly small steps in the gradation of the plate thicknesses that can be produced can be achieved by plugging two intermediate layers into one another, i. H. that the projections of the upper intermediate layer are directed downwards and immerse in the projections of the lower intermediate layer which are also directed downwards.
  • the good mechanical load-bearing capacities can in particular serve to also fasten shear-resistant layers to the other components of the lightweight board.
  • cover layers made of wood-based materials, for example MDF or chipboard or the like, or also plasterboard, or carpets or other floor coverings, all of which can be provided with projections which are designed either as continuous ribs or as individual pyramids, so that a similar toothing effect can be achieved between the cover plate and the closest adapter or intermediate layer plate as between the individual intermediate layer plates.
  • the oblique edges of the pyramid-like projections do not extend to the plate level of the respective plate, but instead provide a kind of “base” for the pyramid-like projection, in which The four corner edges run approximately parallel to each other.
  • a design with such bases ensures that there is always free space between two plates with any arrangement of the individual plates with respect to one another, so that a fluid can be passed through these free spaces.
  • Lightweight construction panels constructed in this way can be used, for example, in the area of room air conditioning as floor, ceiling or wall elements, a cooling or heating medium then being able to be guided through these intermediate spaces of the lightweight construction panels in a manner known per se.
  • This can be a closed cooling or heating medium circuit, for example with water as the heat transfer medium, or it can be an open system in which, for example, air drawn in by a fan is passed through the cavities of the lightweight building boards.
  • a non-planar shape of the lightweight panels can be brought about, for example curved surfaces for the production of vehicle roofs, e.g. B. truck trailers or railway wagons, or it can be curved curves in the area of interior design with partitions or counter devices or the like.
  • curved surfaces for the production of vehicle roofs, e.g. B. truck trailers or railway wagons, or it can be curved curves in the area of interior design with partitions or counter devices or the like.
  • the arched surfaces are characterized by their prestressing with a particularly high vibration resistance.
  • each double pyramid Room volume which can have an overpressure or underpressure compared to the ambient pressure if the corresponding climatic changes are present in the ambient atmosphere.
  • it can therefore advantageously be provided to provide each of these double pyramids with ventilation openings.
  • FIG. 1, 1 generally designates a lightweight building board which has a schematically indicated first covering layer 2, an upper intermediate layer 3, an adapter plate 4, a lower intermediate layer 5 and a second, lower covering layer 6.
  • the first cover layer 2 has downwardly directed pyramid-shaped projections 7 and 7a
  • the adapter plate 4 has similar projections 7b on both sides
  • the lower intermediate layer 5 is identical to the upper cover layer 3 and also has projections 7a.
  • the adapter plate 4 is made of two intermediate layers 3 or 2 which are glued or welded together.
  • the entire lightweight board 1 has a high strength even with regard to shear or bending forces.
  • the individual components are in each case glued to one another at the tip of the projections 7, for this purpose the projections not tapering to a point-like tip, but rather forming a flattened tip with a corresponding adhesive surface or welding surface.
  • the inclined edges of the projections 7 are also not quite pointed, but instead are provided with a phase so that the projections touch each other along such phases and create larger connecting surfaces there, which provide a particularly intensive connection between the individual plates or enable layers from which the lightweight board 1 is composed.
  • An upper intermediate layer 3 is provided under the upper cover layer 2, which can consist, for example, of the same plate as the upper intermediate layer 3 of FIG. 1.
  • the upper half of an adapter plate 4 is shown next to the upper intermediate layer 3, with the projections 7b of the adapter plate 4 do not run conically to the plate surface, but instead form a base 8 towards the plate surface if the pyramid-shaped projections 7 have, for example, four oblique edges.
  • the corresponding four corner edges on the base 8 run parallel to one another, with two
  • Projections 7b on the adapter plate 4 are spaced apart from one another, so that there are free spaces 9 between the bases 8, through which a fluid can be passed, for example. Since the free spaces 9 communicate with one another over the entire surface of the lightweight building board 1, the entire space can be used
  • Plate surface a thermal effect for heating or cooling, for example, by using an appropriate heat transfer medium as a fluid.
  • FIG. 3 shows the design of the adapter plate 4 from FIG. 1 on the basis of a cross section through two projections 7b.
  • FIG. 4 shows the design of an adapter plate 4 based on the cross section through two projections 7b, the lower plate being designed as the intermediate layers 3 or 5 of FIG. 1, as is also used to form an adapter plate 4 according to FIG. 1 or FIG 3 can be used.
  • the upper projections 7b are provided with a base 8, so that on the one hand - as seen from the corresponding adapter plate 4 - there is the possibility of a fluid guide, while on the other hand such a fluid guide is not provided.
  • both projections 7b are each provided with a base 8, so that using such an adapter plate 4 results in the possibility of the adapter plate on both sides seen to carry a fluid and thus allow a particularly intensive flow through the lightweight board 1.
  • an adapter plate for thermal separation, individual intermediate layers or also an adapter plate can be provided with an insulating material, for example with an insulating foam, so that the corresponding projections 7a and 7b are filled with such an insulating material. It can even be provided in a weight-saving manner not to use the actual plates and to fill their projections with such an insulating material, but to use only the insulating material without the actual plate material and to design the pyramid-like projections for this insulating material, as they have the intermediate layers or adapter plates, so that the corresponding toothing and the corresponding spatial expansion is possible by attaching further adapter plates or further intermediate layers to this insulating material plate.
  • an insulating material for example with an insulating foam
  • the adapter plates and the intermediate layers are preferably made from deep-drawn plastic, for example from foils of approximately 0.5 to 1 mm in thickness, although other materials, for example sheets, can also be used.
