Definitions

  • the invention relates to a lattice, in particular a flat lattice (lattice mat) made of metal (such as expanded metal), paper, cardboard or plastic, with lattice nodes, from which lattice webs run to adjacent lattice nodes.
  • a lattice in particular a flat lattice (lattice mat) made of metal (such as expanded metal), paper, cardboard or plastic, with lattice nodes, from which lattice webs run to adjacent lattice nodes.
  • Expanded metal with meshes is known, which e.g. are diamond-shaped or square-shaped. Due to this geometry, longitudinal expansion and transverse contraction are inevitably coupled. This known property results in a relatively low formability of expanded metal on spatially strongly curved surfaces. This limitation is overcome with difficulty by denomination or folding or cutting and double material.
  • the object of the invention is to create a grid which can be adapted to a wide variety of geometrical, in particular also curved, structures. Due to its geometry, the lattice to be created should advantageously have a significantly improved formability to any spatial shape and be suitable for a very wide range of needs, such as Shaping of vehicle body parts, stucco and vault reinforcement, seat shells, sculptural and architectural objects, packaging, inserts in highly moldable sealing sheets etc.
  • a lattice according to the invention can be obtained in a particularly simple manner in that ma offset from row of ashes to row of stitches - in each case two lattice knots are cut transversely and preferably perpendicularly to the conventional ionic "extended cut".
  • the grids according to the invention can be filled or coated with hardening or thermally polymerizing or drying substances or materials and can therefore be used, for example, as a plaster base and as in the roofing area products known in the market known as "lead replacement". Further possible uses are:
  • the presented designs of the grids according to the invention are preferably punched or joined or glued and shaped from homogeneous sheet or strip semifinished products and, analogous to the known expanded metal, they do not have precisely defined flow, bending joints or nodes. In this case, there is even no need to fix the nodes or crossing points if the loosely placed grid strips or wires are held in place by immediately embedding or pressing them into a rigid or elastically hardening mass. As an essential common feature, these grids have a high plastic formability and low elastic springback.
  • FIG. 1 is a perspective view of a grid according to a first embodiment of the invention, with grid bars bent in the grid plane,
  • FIG. 2 shows a top view of a conventional expanded metal grid with individual severed grid nodes
  • FIG. 3 is a plan view of a grid made of wavy bends
  • FIG. 4 is a perspective view of a grid according to a further embodiment of the invention, with grid webs which are bent out of the grid plane in a triangular manner,
  • FIG. 5 is a perspective view of a grating according to a further embodiment of the invention, with grating webs bent out of the grating plane in a trapezoidal shape,
  • FIG. 6 shows a perspective view of a grating according to a further embodiment of the invention, with grating webs having a “positive coupling” that are bent out of the grating plane,
  • FIG. 7 is a perspective view of a grid according to a further embodiment of the invention, with grid webs which are stiffened by folded triangular surfaces.
  • the grid shown in FIG. 1 corresponds to an expanded metal grid.
  • the lattice webs 2, which extend in the lattice plane, x, y plane, in the form of a beam between lattice nodes 1, are bent out in a zigzag shape, so that the distance between the nodes can be increased or reduced with relatively small external forces applied from outside. This shape already results in a considerably improved formability of the lattice on spatial shapes of all kinds.
  • the lattice shown in FIG. 2 is a normal expanded metal lattice, in which two lattice nodes 1 a are separated only staggered from row of stitches to row of stitches by a separating cut 1 c perpendicular to the actual “drawn cut” ld.
  • Such a grid is characterized on the one hand by light adjustability and on the other hand characterized by excellent formability.
  • FIGS. 3 (a) and (b) A corresponding grid is shown in FIGS. 3 (a) and (b), the grid bars here not being formed from a metal sheet as in FIG. 2, but from metal wires.
  • Fig. 3 (a) zigzag or wavy wires 5, 6 are lined up in a parallel orientation, so that there are bellies 7 and contact points 8 between them.
  • the wires 5, 6 are in turn staggered from stitch row to stitch row, clamped to one another at every third contact point, welded, soldered, etc., while the intermediate contact points are loose.
  • 3 (b) is of basically the same structure, only the wires 5 'intersecting the wires 6 1 at an angle ⁇ , as a result of which intersection points 8' now result instead of contact points 8.
  • the bracket is the same as in the embodiment of Fig. 3 (a).
  • the angle ⁇ is preferably ⁇ 90 °, optimally 30 ° ⁇ ⁇ 60 °, which results in particularly good stretching and compression behavior.
  • this grid offers a particularly good ability to be glued or coated on both sides with foils or the like.
  • This two-sided, flat gluing can be done either in the flat position of the grille or after molding to almost any room contour, which enables a particularly light and rigid sandwich or shell construction.
  • the lattice webs 2 are in turn connected to one another at the buckling points in the form of a platform 3 by correspondingly bent lattice webs 2 '.
  • the buckling of the bars 2 ' is usually opposite to the buckling direction of the bars 2, so that the platforms 3' of the bars 2 'lie in the same plane as the bars 1.
  • Fig. E If one considers the grid according to FIG. 6 as "deep-drawn from a perforated square plate", the grid according to FIG. 7 results directly if the perforated fields are not punched out, but rather only slotted and in the appropriate diagonal then included in the deep-drawing shaping in such a way that the alternating up and down ge of the nodes, combined with a 45 ° inclination of the webs, automatically results in a vertical position of the folded triangular surfaces 4.
  • This shape brings about an extraordinary stiffening of the webs 2, 2 'against kinking failure under external load. If certain deviations from this ideal geometry are permitted, then this lattice is still considerably more spatially formable than expanded metal.
  • the grids according to FIGS. 4 to 7 can be glued on one or both sides, either continuously or partially, either before or after molding.
  • the plates and shells constructed in this way which due to their design are “closed-pore”, that is to say non-aerated, have excellent “aeration”.
  • the grids according to FIGS. 4 to 7 thus also enable a particularly light and rigid, and also particularly flat, also integrally formed, that is to say spatially curved, construction of built-in tanks and storage containers. If such containers with a grid type according to FIG. 7 are stiffened, the folding triangles 4, which function excellently as baffles, must however have through openings, since otherwise "closed pores” result.

Abstract

Dans un treillis, notamment un treillis plat (grillage), en métal (tel que du métal déployé), en papier, en carton ou en plastique, les noeuds (1) du treillis sont reliés par des traverses (2) qui s'étendent en étoile entre des noeuds adjacents du treillis. Les traverses (2) sont ondulées ou pliées en zigzag entre les noeuds (1) du treillis, de sorte qu'en appliquant des forces extérieures on peut augmenter ou réduire l'écartement entre les noeuds (1).
