Definitions

  • the invention relates to composite components made of a metal wire mesh and a plastic cover, which is rigidly connected to the metal wire mesh at the crossing points by means of connecting clamps.
  • Composite components of this type are known from DE-PS 22 47 358. They obtain their static rigidity from the fact that they are barrel-shaped and the plate-shaped plastic cover is arranged at a distance from the metal wire mesh.
  • torques occur at the connection points between the crossing points of the metal wire mesh and the plastic cover. The greater the distance between the metal wire mesh and the plastic cover, the greater these moments.
  • the connection points must be attached to the crossing points of the metal wire mesh as free of torque as possible, which leads to a complex design of the connection clamps, particularly when larger areas are to be covered with the composite components.
  • the invention has for its object to improve the known composite components in terms of their rigidity without torques occurring at the connection points between the metal wire mesh and the plastic cover or complex connection clamps for receiving such torques are required.
  • the task is solved by composite components according to the patent claims.
  • the new composite components are based on the lattice girder principle, but in a flat design.
  • Two plastic covers (1) and (2) form the upper and lower chord of the lattice structure.
  • the support grid (3) formed from metal wires or rods takes over the function of the supporting web between the upper and lower chord. In case of low load or high own stiffness of the support grid can be flat, such as a conventional structural steel mat. If a higher static rigidity is required, a three-dimensional lattice is used.
  • the metal wires or rods approximately perpendicular to the plane of the plastic covers bent periodically and at the vertices (4) with the respective adjacent art 'fabric cover rigidly connected.
  • the grille consists of metal bars running at right angles to one another.
  • the metal bars In order to achieve the required rigidity, it may be sufficient to periodically bend the metal bars in one of the lattice directions in the sense described.
  • the metal rods are preferably bent in this way in both grating directions.
  • the periodic bending increases the distance between the upper and lower chord of the lattice structure, thereby increasing its static rigidity.
  • the plastic covers In order to largely exclude torques that act on the plastic covers, the plastic covers are fastened as close as possible to the metal bars or the apexes of the metal bars.
  • Fig. 3 shows a detailed solution in which this connection is realized with a small distance between the plastic cover and the metal bar grille.
  • Adjacent metal rods running in the same direction are preferably each curved in opposite directions, so that their apexes are offset from one another by half a period length P.
  • the metal rods are preferably curved in opposite directions in both lattice directions and at the respective vertices Crossing points connected to each other. With this design, a high and a low-lying crossing point follow each other for each metal rod.
  • the metal bars can be welded at the crossing points.
  • a connection clamp (10) which also serves for connection to the plastic cover, is more expedient.
  • the metal rods are preferably bent approximately in the form of a sine curve, as shown in FIG. 1. However, they can also be curved in a zigzag, trapezoidal or rectangular shape with small radii of curvature at the vertices; see. Fig. 2.
  • the bending of the metal bars is the same in every period and preferably every period P long.
  • This design is suitable for large flat or barrel-shaped curved composite components.
  • a slight inclination of the plastic covers (5) and (5 ') can be more advantageous.
  • the lengths of the individual bending periods (P 1 , P 2 , P 3 %) of the metal bars can also become smaller with decreasing overall thickness, as shown in FIG. 2.
  • the new composite components not only have an increased static rigidity, but also ensure the presence of two spaced-apart plastics covers at the same time increased heat and sound insulation. They are therefore suitable for the erection of self-supporting, large-area structures or parts thereof, such as light walls, soundproof walls, light roofs, greenhouses, soundproofing tunnels for roads and railways, factory halls, etc.
  • both the plastic covers and the metal rods can be made from small ones Individual elements can be strung together.
  • the rigidity and load-bearing capacity of the entire component is not adversely affected, provided that the joints between the individual sub-elements in the total area of the component are offset from one another.
  • connection point can be subjected to tension.
  • ends of abutting metal rods can be connected to one another by loosely attached tubular sleeves.
  • the edges of neighboring plastic cover elements can be connected using suitable clamping profiles.
  • the plastic covers and the metal bars must be dimensioned according to the traffic loads to be absorbed.
  • the support grid is preferably made of steel bars, but bars made of aluminum or other metals can also be used. Depending on the size of the entire structure and the traffic loads that occur, steel bars of, for example, 5-20 mm in diameter can be considered.
  • the steel rods are preferably galvanized or coated in a corrosion-resistant manner.
  • connection clamps for the crossing points of the support grid are preferably also made of metal and can be made, for example, by die casting from aluminum.
  • a design according to FIG. 3 is expedient, in which the metal bars (6), (7) are pushed into slots (8) arranged in a crosswise manner and are immovably clamped by a threaded ring (9).
  • the plastic cover (1) is attached to the same connecting clamp (10).
  • it carries a threaded shaft (11) which leads through a corresponding hole in the plastic cover.
  • the threaded shaft (11) can also be covered with an elastic material.
  • Hollow chamber panels or solid profile panels which can be flat or corrugated, are suitable as plastic covers.
  • Hollow chamber sheets for example extruded double-wall sheets, have the advantage of high inherent rigidity with low weight.
  • Suitable plastics are polycarbonates, polymethyl methacrylate, polyvinyl chloride, glass fiber reinforced polyesters or polyolefins. When using hollow chamber profiles, extruded double-wall sheets made of polycarbonate are preferred.
  • Solid profile panels can be used with a thickness of 2 - 8 mm, for example. Suitable hollow chamber profiles can have a thickness of 8 - 40 mm.
  • the top and bottom covers can be made of the same or different plastic material.
