Definitions

  • the invention relates to inclined multi-wall sheets, in particular multi-wall sheets made of aromatic polycarbonates or multi-wall sheets in general. These consist of at least two plates arranged parallel to one another, which are connected to one another by webs running in certain arrangements.
  • the most common embodiment is the web double plate, in which the webs run at regular intervals from one another perpendicularly to the plane of the plate, so that the cross-section results in the image of rows of rectangular chambers.
  • other geometries such as, for example, PMMA (polymethyl methacrylate) products have been used.
  • B. developed the so-called truss geometry (Degussa, Vedril).
  • the webs form an angle of approx. 45 ° C with the plates, which leads to lower stresses and higher rigidity with a similar weight per unit area due to the improved transmission of transverse forces.
  • additional support spacing of the load-bearing elements can be selected when installing these products, which reduces the material expenditure for the support structure and the time required for installation.
  • a structure corresponding to the PMMA lattice geometries has not yet been implemented for polycarbonate multi-wall sheets. Only a so-called X-plate of 16 mm thickness is known, in which, in addition to the vertical webs, two 45 ° webs per chamber are integrated into the geometry. Due to the additional inclined webs, this panel has a weight per unit area of 3.3 kg / m2, which is significantly higher than that of standard 16 mm PC wall panels (approx. 2.7 to 3.0 kg / m2). Due to the different material properties (e.g. modulus of elasticity), it is not possible to simply transfer geometries to polycarbonates, as they have proven themselves in the production of PMMA sheets. If the load capacity is sufficient, the plate will buckle before the maximum load is reached.
  • modulus of elasticity Due to the different material properties (e.g. modulus of elasticity), it is not possible to simply transfer geometries to polycarbonates, as they have proven themselves in the production of PMMA sheets. If the load capacity is sufficient, the plate
  • inclined web multiple plates made of aromatic polycarbonates (PC), consisting of at least two plates arranged parallel to one another at a predetermined distance, which are connected to one another by webs arranged in between, the one part of the webs - seen in cross section - upper and lower
  • the zigzag plate connects, while the other part attaches to the upper or lower plate in the nodes of the sloping webs and runs perpendicular to the opposite plate, have a sufficient load capacity, since the buckling is shifted beyond the maximum load.
  • a special embodiment of the invention are multi-slanting web plates, in particular double wall plates, which are characterized in that, with a thickness of approximately 0.7 mm for the two parallel plates, the sloping webs form an angle of approximately 45 ° with the plates and their thickness is approximately 0.4 cm, while the thickness of the perpendicular webs is approximately 0.2 mm.
  • the spacing of the latter webs is approximately 16 mm, as is the thickness of the web double plates.
  • the end web delimiting the plate on the right and left is preferably about 0.4 mm thick. With the specified dimensions, the basis weight is approx. 2.7 kg / m2.
  • Fig. 1 shows an image of the preferred embodiment.
  • the inclined web multiple plates according to the invention are produced by the known methods by extrusion.
  • suitable coatings for further reinforcement, for improved flame retardancy, etc. can be used according to the known methods, for. B. by coextrusion or lamination.
  • the plates according to the invention are used in the same fields as the known double wall plates.
