    专利说明:

    The invention relates to a grid structure, consisting of intersecting longitudinal and transverse elements, such as wires strands, ropes, rods or profiles, which are connected at the intersections with immovable nodes.
    Grid structures of this type are used as components in the form of flat or corrugated supporting or protective gratings, the shear strength of the nodes ensures that the grid undergoes little deformation even at high loads. For connecting the wires in the nodes, welding connections, clamps or additional wire material or the like have hitherto been used.
    A lattice structure of this type is disclosed in AT-PS 409 506 B. It consists of rod-shaped over and under straps, between which connecting rods are welded. On the one hand, these welding points, which form the nodal points, bring about structural changes and, on the other hand, cause a high manufacturing outlay when welding the strap webs together. The latter also applies when using mechanically processed fasteners, which also have a high labor and cost.
    The invention is based on the object to avoid these disadvantages and to provide a lattice structure of the aforementioned type whose nodes have no welds or additional materials and it is efficient and economical to produce.
    This object is achieved according to the features of claim 1.
    This creates between the longitudinal and transverse elements an immovable connection that can be produced without foreign fasteners and with relatively little effort. In addition, a longer lifetime of the lattice structure results because there are no weakening welds or the like at the nodes.
    The inventive grid can be realized in various embodiments. In a first embodiment, the invention provides for the longitudinal and transverse elements of the grid to be provided with loops which are open or closed, untwisted or partially pre-twisted along the elements and perpendicular to the lattice plane, which are twisted together at the points of intersection of the elements and thus form nodes , To facilitate this connection, the loops of the longitudinal wires are arranged in the longitudinal direction of the wires, while the loops of the transverse elements are aligned transversely to the longitudinal direction of the wires. However, it is also readily possible, conversely, to provide the longitudinal wires with loops arranged transversely to the longitudinal direction of the wires, while the transverse elements are provided with loops arranged in the longitudinal direction of the wires.
    In a second embodiment, the invention provides that the grid of at least twice out and performed at the intersection of the wires into each other and composed of self-twisted longitudinal and transverse elements.
    It is expedient, preferably to provide the longitudinal wires, strands, ropes, rods or profiles with along the same distributed passages for receiving the passing through them or passing transverse elements. But it is also possible here, conversely, to provide the passages in the transverse elements and to pass the longitudinal wires through the transverse elements.
    In a variant of this embodiment, it is provided as a further advantage that the doubly guided longitudinal and transverse elements are twisted only in the region of the intersection.
    With regard to the stability of the grid in the loaded state, it is advantageous if the longitudinal and transverse elements lying in a plane are aligned at right angles to each other. However, the formation of the nodes according to the invention is also readily applicable to gratings with other crossing angles.
    It is also advantageous manufacturing technology, if the distances between the nodes of the grid in the longitudinal or transverse direction are uniform.
    Advantageously, the longitudinal and / or transverse elements are at least partially made of high strength steel, preferably with a strength of 700 N / mm <2> to 2800 N / mm <2>.
    Embodiments of the invention are explained below with reference to the drawing. Show it:<Tb> FIG. 1 <SEP> is a perspective schematic representation of a grating structure according to the invention;<Tb> FIG. 2a, 2b <SEP> the longitudinal and transverse elements of the grid according to FIG. 1 before the twisting of the wire loops, in the side view or in perspective,<Tb> FIG. 3a, 3b <SEP> show two schematically illustrated phases of the production process of the lattice structure according to FIG. 1 and FIG. 2 respectively;<Tb> FIG. 4 shows a second embodiment of the grid structure according to the invention in perspective;<Tb> FIG. 5a, 5b <SEP> is a side view of a respective longitudinal or transverse wire of the lattice structure according to FIG. 4;<Tb> FIG. 6a, 6b <SEP> represent a node of a grid structure according to FIG. 4, in two phases of the production process; and<Tb> FIG. 7 shows a further embodiment of a grating structure according to the invention, also in perspective.
    The lattice structure 1 according to FIG. 1 to FIG. 3 consists of longitudinal elements 2 and transverse elements 3 preferably made of steel, which are provided at regular intervals with vertical loops 4 and 5 respectively. These longitudinal and transverse elements are in particular wires strands, ropes, rods or profiles. But it can also be combination products with steel and plastic and / or plastic products and sandwich elements thereof.
    Such a lattice structure 1 is suitable for various applications. So they can be inserted or usable for example for reinforcements in concrete, asphalt, as reinforcement in mining or the like.
    But they can also be used for other purposes, such as embankment protection on earth surfaces of any kind or in protective barriers against avalanches, rockfalls or against other natural hazards.
    In addition, such grating structures for indoor and outdoor applications can be applied to buildings, such as a permanent or mobile separation element, which in high-strength execution u.a. the vandal security increased.
    These gratings are endless and rollable depending on the version, which extends the application possibilities and in particular simplifies transport and installation.
    According to the invention, this grid structure 1 is firmly twisted together at the intersections 6 of the wires and thus form nodes 7, which are shear-resistant under load and withstand deformation of the grid.
    In this lattice structure 1, the longitudinal and transverse elements 2 and 3 are arranged perpendicular to each other in a plane lying, wherein the nodes 7 are removed from each other both in the longitudinal direction and in the transverse direction at equal distances.
    But it is also possible, of course, to provide different distances for both directions. In both cases, the geometry of the grid, for example, comparable to that of welded steel mesh.
    As a further variant, the nodes 7 could not be approximately rectangular, but zigzag-shaped. In practice, however, the rectangular arrangement is to be regarded both manufacturing technology and in terms of their mechanical properties as advantageous.
    For fastening the lattice structure 1, for example, on a comprehensive frame closed anchoring loops 8 are provided at the ends of the longitudinal and transverse elements 2 and 3, which allow without additional means a uniform around the grid attachment.
    2a and 2b show a prepared with loops 4 and 5 longitudinal wire 2 and transverse wire 3 and in turn for their part also prepared for assembly with transverse transversely by loops 5 loops 5 prepared cross-wire.
    Fig. 3a illustrates a prepared for twisting the loops 4 and 5 crossing point 6, wherein the wires 2 and 3 are inserted in accordance with the invention in a defined spaced grooves 9 a mounting plate 9 or the like to a positioning and holding for the To allow twisting of the same. The grooves 9 are arranged at such distances from each other in the mounting plate 9 that they correspond to the mesh sizes of the lattice structure 1.
    Fig. 3b shows the point with mutually twisted loops 4 and 5. They form at this point an immovable shear-resistant node. 7
    The lattice structure 10 of Fig. 4 and Fig. 5a and 5b differ from lattice according to Fig. 1 mainly in that in him the longitudinal and transverse elements 2 and 3 are guided twice and each twisted with itself , wherein the longitudinal wires 2 distributed in the longitudinal direction arranged passages 11, through which the transverse elements 3 are guided.
    Fig. 5a shows a prepared for assembly longitudinal wire 2 with evenly distributed passages 11 for receiving the cross members.
    Fig. 5b illustrates a likewise prepared for assembly transverse wire 3, which is initially twisted only to the first intersection point 6 of the lattice structure 10.
    As can be seen from Fig. 6a and 6b, the transverse wire 3 is inserted through the first passage 11 of the longitudinal wire 2 during assembly of the grid structure 10 and then further twisted until the next pass, where he also in the region of the intersection point 6 is firmly twisted with the longitudinal wire 2. This process is repeated until the transverse wire 3 is completely guided through all the passages 11 of the longitudinal wires 2. If the passages 11 are dimensioned correspondingly large, results in a verschränkbare in a certain angle and thus also rollable structure.
    The lattice structure of Fig. 7 differs from that of Fig. 4 only in that the longitudinal and transverse elements 2 and 3 only in the region of the intersection points 6, in which they form the nodes 7, twisted are. Outside these positions, they remain untwisted as double or multiple wires, which can be provided at the ends with closed anchoring loops 8 for attaching the grid to a comprehensive frame him.
    The embodiments according to FIGS. 1, 4 and 7 can, of course, also be implemented in the inverse of the described arrangement. In the embodiment according to FIG. 1, the longitudinal wires 2 then have loops arranged transversely to the longitudinal direction, while the transverse elements 3 are provided with loops arranged in the longitudinal direction.
    In the embodiments according to FIGS. 4 and 7, the passages 11 are arranged in the transverse elements 3 and 3, respectively, and the longitudinal wires 2 and 2 are formed by the transverse elements 3 and 3, respectively Passed through.
    The longitudinal and / or transverse elements are advantageously made of high-strength steel, preferably with a strength of 700 N / mm 2 to 2800 N / mm 2. Thus, these nodes are still held together after twisting with a higher rigidity. It can also be provided with a lower strength, the longitudinal or transverse elements.
    With this inventive lattice structure, any desired mesh shapes or sizes can be produced. In principle, these longitudinal and transverse elements could not be arranged as shown at right angles to each other, but similar to, for example, in wire mesh, where rhomboid-shaped meshes are formed.
    The longitudinal and / or transverse elements could also be provided with bent by approximately 360 ° loops, through which the transverse or longitudinal elements are guided with or without twisting, as can be seen from the other figures. Advantageously, the knots are comprised of at least one turn of circular 360 ° loops preformed at the intended intersections and formed on the transverse wires during assembly by passing, returning and again passing through the loops of the longitudinal wires. The loops are threaded so that they are positioned with respect to the lattice plane mirror image of the loops of the longitudinal wires.
    It is also possible that not all intersections with a connection resp. Twisted are formed. For example, only every second or after a number of elements crossing points can be provided with connections, while the remaining are arranged adjacent to each other.
