Definitions

  • the invention relates to a grid, in particular a flat one Grid (grid mat), made of metal (like expanded metal) paper, Cardboard or plastic, with lattice knots, one of which is jet-shaped Lattice webs run to neighboring lattice nodes (see e.g. US-A-2 125 583).
  • a grid in particular a flat one Grid (grid mat), made of metal (like expanded metal) paper, Cardboard or plastic, with lattice knots, one of which is jet-shaped Lattice webs run to neighboring lattice nodes (see e.g. US-A-2 125 583).
  • Expanded metal with meshes is known, which e.g. are diamond-shaped or square-shaped. Based on these Geometry is inevitably longitudinal expansion and transverse contraction coupled. This known property results in a relative one low formability of expanded metal on spatially strong curved surfaces. This restriction is due to denominations or folding or cutting and material doubling overcome with difficulty.
  • the invention has for its object to provide a grid the most diverse geometrical, in particular also curved structures is adaptable. This is said to be advantageous creating grids due to its geometry an essential have improved formability to any room shape and are suitable for a very wide range of needs, e.g. Shaping of vehicle body parts, stucco and vault reinforcements, Seat shells, sculpture and architecture objects, Packaging, inlays in highly formable sealing sheets Etc..
  • the first step was a solution found, in which the webs or bars of the grid between the Intersection or nodes in the x, y direction, i.e. in the Lattice plane bent out in a wave, meander or zigzag shape or buckled, so that with relatively little from the outside applied molding forces the distance between the nodes can be enlarged or reduced even further.
  • this shape is already significantly increased Formability.
  • one according to the invention Obtain grids in a particularly simple manner by - offset from row of stitches to row of stitches - two grid knots each through a separating cut across and preferably cut perpendicular to the conventional "stretch cut".
  • the presented designs of the grid according to the invention are preferably made from homogeneous sheet or strip semi-finished products punched or assembled or glued and shaped and they do not quite point analogously to the known expanded metal precisely defined flow, bending joints or nodes.
  • these grids have a high plastic formability and low elastic springback.
  • the grid shown in Fig. 1 corresponds to an expanded metal grid. Which are in the grid plane, x, y plane, radiating there are grid bars 2 extending between grid nodes 1 zigzag bent, so that with relatively small of the distance between the nodes can be enlarged or reduced.
  • This Shaping already achieves significantly improved formability the grid of spatial forms of all kinds.
  • the grid shown in Fig. 2 is a common expanded metal grid, in which only staggered from course to course two grid nodes 1a through a separating cut 1c are cut perpendicular to the actual "stretch cut" 1d.
  • a grid is easy to manufacture and on the other hand, thanks to its excellent malleability out.
  • FIGS. 3 (a) and (b) A corresponding grid is shown in FIGS. 3 (a) and (b), where here the webs are not made of sheet metal as in FIG. 2, but are formed from metal wires.
  • Fig. 3 (a) zigzag or wavy wires 5, 6 in parallel alignment lined up so that between give them bellies 7 and points of contact 8.
  • the wires 5, 6 are in turn offset from course to course brackets every third point of contact, welded, soldered etc. while the in between Points of contact are loose.
  • 3 (b) is from basically the same structure, only the wires here 5 'cut the wires 6' at an angle ⁇ , whereby instead of points of contact 8 now crossing points 8 ' surrender.
  • the bracketing is the same as for the Embodiment according to Fig. 3 (a).
  • the angle ⁇ is preferably ⁇ 90 °, optimally 30 ° ⁇ ⁇ 60 °, from which a particularly good stretching and upsetting behavior also results.
  • a Corrugated cardboard with an intermediate layer according to a grid according to figures has an absolutely identical, defined one Willingness to kink in both directions. This in both directions The same readiness to buckle does not only result in the area of Cardboard manufacturing benefits, but more in the area Reuse of corrugated cardboard by the "on-site one-off production" made-to-measure packaging from well-preserved used material is significantly simplified.
  • the grids according to FIGS. 4 to 7 either one-sided or two-sided, either before or after molding or partially glued over a large area.
  • the so constructed Plates and bowls are in contrast to the widespread Hexagonal honeycomb sandwich components (honey comb sandwiches), due to its design, it is "closed-pore", so it cannot be ventilated are excellent “ventilability”.
  • the grids according to Figures 4 to 7 thus also allow a special light and stiff, as well as particularly flat, also molded, So spatially curved construction of built-in tanks and storage containers. Are such containers with grid type according to FIG. 7 stiffened, so they have to function excellently as baffles Folding triangles 4, however, have openings, otherwise "closed pores” result.
