Definitions

  • the invention relates to an all-round shear-resistant three-dimensional welded lattice body, consisting of two parallel, flat lattice mats made of crossing and at the crossing points welded longitudinal and transverse wires and of diagonally running between the lattice mats and keeping them at a predetermined mutual distance, with a wire each of the two wire mesh welded web wires.
  • Lattice bodies of this type are known from DE-A No. 1659144.
  • the webs are formed by continuous, wavy or zigzag-shaped wires in the direction of the longitudinal wires of the lattice mats, which run in pairs in alternately inclined planes such that four webs meet at each point and the edges one on each lattice mat Form pyramid.
  • the webs are welded to one of the two grid mats with a wire crossing point.
  • each bridge wire forms a thermal bridge, by means of which the insulating property of the composite body is reduced.
  • the aim must be to keep the number of thermal bridges as small as possible, which contradicts the seamless stringing together of pyramid-shaped bridge wire groups in the known all-round shear-resistant lattice bodies.
  • the inclined arrangement of the web wires serves the purpose of absorbing shear stresses occurring between the grid mats forming the belt surfaces of the grid body.
  • shear stresses in the case of components loaded transversely to their plane in the support area, i.e. At the edges of the lattice body, the largest, but practically zero in the middle, not only material can be saved, but also the formation of thermal bridges can be reduced by the fact that inclined web wires are only in the support area, whereas in the middle area of the lattice body they run perpendicular to the lattice mats Bridge wires are arranged. Even such designs are not possible with the known shear-resistant lattice bodies on all sides.
  • the invention is now concerned with the task of designing an all-round shear-resistant lattice body of the type specified in the introduction in such a way that it can be easily manufactured and in particular enables the web wires to be welded to the lattice wires with the aid of simple welding tongs.
  • the designer enables the designer to better adapt the lattice body to different static or thermal conditions.
  • This object is achieved in the lattice body according to the invention by the combination of the features that cut straight web wires obliquely to normal planes on the longitudinal wires and either other cut longitudinal wires or the same cut longitudinal wires additionally slant to normal planes on the transverse wires of the two grid mats, the two ends each of these web wires are welded to the two grid mats at a distance from the ends of the other web wires and from the points of intersection of the grid wires.
  • DE-A No. 2657667 discloses a lattice body that is only shear-resistant in the longitudinal direction, the overall structure of which is essentially determined by its manufacturing process; after this will be Supports arranged vertically next to each other, each consisting of two belt wires and parallel web wires running diagonally to them, and produced by strip-shaped cutting of a diagonal grid, with the help of cross wires connecting the upper and lower belts, connected to form a grid body.
  • the obliquely arranged web wires give a similar all-round shear stiffness as in the known lattice bodies with web wires running along the pyramid edges to a wire crossing point, but the combined use of straight straight wires and a displacement of all web wire welding points against one another and against the wire crossing points
  • the mesh mats ensure that only two wires meet at each welding point, so that perfect welding can be achieved using simple welding tongs.
  • the lattice body according to the invention is to be used as a walk-in supporting structure, it is also advisable to cut the web wires to length with the outer sides of the two lattice mats so that they do not protrude beyond the lattice mats.
  • the straight web wires used in the context of the invention already ensure a buckling stiffness which is desirable for rust-like structures, but this can be increased if necessary by designing the web wires with a larger diameter than the grid wires.
  • the accessibility of such structures can be further favored by the fact that the grid wires of at least one of the two grid mats have a profiled surface.
  • a spatial lattice body according to the invention can of course also be used in a conventional manner as a component, a layer of heat-insulating material then being arranged in its central region at a distance from the two lattice mats.
  • Two lattice mats G1 and G2 with aligned longitudinal and transverse wires L11-L1 n and L21-L2n or Q11-Q1n and Q21-Q2n are at a predetermined distance from each other. They are held at this distance by cut straight web wires Sa, Sb or Sc, Sd, of which the former alternately in opposite directions obliquely between aligned longitudinal wires L11, L21 or L13, L23 etc., i.e. obliquely to normal planes on the longitudinal wires, and the latter alternately run in opposite directions obliquely between cross wires Q11, Q21 or Q13, Q23 etc.
  • the lattice body is therefore stiffened both in the direction of the longitudinal wires of the lattice mats and in the direction of the transverse wires thereof and therefore shear-resistant on all sides. As can be seen particularly clearly in FIG.
  • the ends of the bridge wires are at points P1 and P2 is welded to the longitudinal or transverse wires of the lattice mats G1 and G2, which are located at intervals from crossing points K of the lattice wires, so that these points are easily accessible for simple welding tongs.
  • each web wire S runs from a point P2 lying within a longitudinal wire section of the lower lattice mat G2 to a point P1 on a longitudinal wire section of the upper lattice mat, which is offset both by approximately a longitudinal wire pitch and approximately by a transverse wire pitch with respect to the point P1 on the grid mat G1.
  • each web wire S has a stiffening effect both in the longitudinal direction and in the transverse direction of the lattice body.
  • the grid wires of a mat to be walked on can advantageously be profiled, for example ribbed, in order to increase the grip.
  • By increasing the diameter of the bridge wires their buckling stiffness and thus their load-bearing capacity can be reduced of the structure can be increased.
  • Such rust-like structures can be used for work platforms, covers, formwork beams, but also for prefabricated floor, wall and ceiling elements.
  • a spatial lattice body according to the invention is suitable in a conventional manner for the production of prefabricated components, the webs Sa, Sb, Sc and Sd of which in the central region of the lattice body Wear core layer KS made of heat-insulating material, whereby the free-standing lattice mats G1 and G2 can be embedded in concrete and then form wall shells. It can be seen that the inclined webs running in different directions support the core layer and hold it firmly in the central region of the lattice body.
