Definitions

  • the present invention relates to a textile grid with two groups in groups of mutually crossing directional lattice structure threads. Such a textile grid becomes practical
  • the intersecting lattice structure threads of high strength.
  • the invention is based on improving the reinforcing effect essentially by direct contact between the lattice structural threads, which ultimately bear the load and the adjacent tar layers of the substructure or superstructure of the road by direct adhesion to the boundary layers, even if in particular the substrate, on which the textile grid is to be placed first, has a ripple, which so far only under a considerable thick layer of bituminous adhesion promoter can be overcome.
  • the adhesion-improving surface elements can thus follow the short-wave and long-wave ripples in the substrate and in this way draw the relatively rigid lattice structure fibers toward the substrate, so that the adhesion-promoting hot bitumen layer, which is ultimately the textile lattice before the application of the tar coating layer holds on the ground, only relatively thin is needed and the reinforcing effect of the directional lattice structure threads with respect to the composite material road "only requires a small matrix volume.
  • the reinforcement is therefore achieved mainly by the virtually direct contact between the adjacent tar layers, so that the micro-movement of the adjacent tar layers remains low and is not affected by material-fatiguing long-term movements.
  • this grid internal dimension represents the distance between adjacent individual or bundled lattice structure threads. According to the invention, this grid internal dimension is always slightly smaller than the length of the flat elements laid in this direction, so that they can be placed close to the substrate, following the long or short waviness of the substrate, thus avoiding a lattice structure element in the air as it were ,
  • the lattice structural element is then pulled by the surface element flooded with hot bituminous material in the direction of the substrate, in particular also because the flat elements are only slightly longer than the respective internal grid dimension.
  • the oversize of the surface elements results practically from the amplitude of the waviness and, taking into account the grating structure elements, can also be approximately calculated.
  • the flat elements act because they are inundated or impregnated by the hot bituminous bonding agent, depending on the material and porosity of the flat elements, in the sense of a holding layer that holds the textile grid in spite of the necessary grid rigidity in the direction of the ground.
  • the textile grid is made so that it is opened as a role.
  • This offers the advantage that the roll material practically in the longitudinal direction of the substrate - here the road - can be handled immediately before the upper tar layer is applied.
  • the roll width is on the order of between about 1 and about 5 meters, but can also be significantly wider when it comes to the use of such textiles grid for highways.
  • This measure makes use of previously applied hot bituminous materials on the road surface for an immediate material-bound connection between the road surface and textile grid by the corresponding adhesive properties of the hot bituminous layer on the one hand and the bituminous coating of the textile grid on the other hand.
  • the permeability of the flat elements in the normal direction to the textile grid is necessary so that the hot-bituminous bonding agent can flood the laid on him textile grid. Therefore, the permeability is of considerable importance.
  • the permeability points can then also be reinforced along the entire length of the lattice structure threads in their respective installation direction. with the exception of those points that are required by the other group of lattice structural threads.
  • the flat elements can be formed by Lunten, preferably Glasmaschinelunten.
  • Lunten can be introduced between two adjacent groups of the lattice structure threads. These Lunten have however in each case a larger one
  • the flat elements can also be long strips or foils or comparable nonwoven material having a width which is smaller than the grid internal dimension, so that laterally of these flat elements also sufficiently large and long permeability sites form, which are necessary for flooding the flat elements in the laying of the textile grid are.
  • Long belts / films or similar nonwoven materials can be caused in particular by exploiting the shrinkage effect.
  • the material of these long strips, etc. in the width direction should be compared to the material of the grid Structural threads in the same direction have the greater shrinkage behavior.
  • the excess length of the flat elements in relation to the length of the running in this direction lattice structural threads can be achieved in various ways.
  • the excess length of the flat elements can be realized, for example, by an increased feed speed of the flat elements in relation to the speed of the lattice structure threads laid in the direction of the flat elements.
  • the increase in the feed rate is in one part per thousand to one-digit percentage range and can possibly be optimized by experiment. On the other hand, it can also make sense to provide the flat elements of a material with predetermined shrinkage behavior, while the running in the laying direction lattice structure threads then have a relation to this shrinkage behavior increased shrinkage behavior.
  • the excess length of the flat elements can be treated by simple temperature treatment of the pre-fabricated textile grid with a temperature corresponding to the shrinkage temperature of the directional lattice structural threads. It will then use a shrinkage of these lattice structural threads, which is stronger than any shrinkage of the flat elements, so that in the finished fabric grid after shrinking the flat elements ultimately run with an excess length in their individual lattice free surfaces.
  • the textile grid essentially consists of the direction-giving and the tensile strength-providing lattice structure threads and the flat elements used as laying optimizers.
  • the direction-giving lattice structure threads can therefore be designed in the form of a tissue or a lamina bound at their intersections.
  • the bond between the directional lattice structure threads can, except by interweaving at this point readily be performed as a bond.
  • the lattice structural threads at least the
  • the invention relates to a device for producing one of the two embodiments of the textile grid according to the invention.
  • This device is advantageously equipped with band WebMften, which are provided for guiding the wide-extending long belts or the like.
  • the yarn eyes required for this purpose also have broad guiding properties and are either configured as wide-lying elliptical, oval thread eyes or have laterally open cross-sections, from which the long objects fed via the thread eyes can project laterally.
  • roller pairs into consideration which are either free-spinning or rotationally driven at conveying speed.
  • the flat elements are supplied individually coming from a feed gate or they come from a tree and must be cut before the individual laying in the lattice open areas on a slitter in narrower long bands before they are then fed to the band-WebCften.
  • the width of the tree from which the Langgutmaterial is subtracted less than the width of the warp beam, since naturally the respective widths of the individual Kettfäden of the Langgutmaterial may not be occupied.
  • FIG. 1 shows a first embodiment of the invention in top view
  • the figures show a textile grid according to this invention.
  • Such textile grid consists of two groups of groups mutually crossing directional lattice structure threads 2; 3. This creates a large-meshed grid, which is formed by ckende grid clearing surfaces and in which at the intersections 4 of the grid 1, the respective groups are routed together.
  • a large-meshed grid which is formed by ckende grid clearing surfaces and in which at the intersections 4 of the grid 1, the respective groups are routed together.
  • This invention therefore has the advantage that the lattice ter Jardine laid on the one hand without additional excess on the substrate to be reinforced, while on the other hand, the flat elements of the predetermined between the individual lattice structural thread contour of the ground due to their excess length can easily follow and in this way outside the Reinforcement points provided by the lattice structural threads can contribute their positive contribution to the reinforcement as an intermediate layer.
  • Fig.la shows the longitudinal view of the textile grid according to the invention and there in particular also the respective excess with which the individual flat elements within the grid, which is spanned by the lattice structure threads, are laid. It is not a limitation of the invention if the oversize of the flat elements is present not only in a single direction within the textile grid, but also in the direction transverse thereto, as a result of a preformed curvature, as shown for example in FIG. so that the flat elements can then also insert into corresponding depressions of the substrate as soon as they are glued there, for example over bitumen-hot material.
  • the laying direction is here by the presentation of the textile grid as a role (see Fig.2a), the longitudinal direction of the role, so that there are relatively long textile mesh, which can be easily easily laid even on large areas.
  • the present invention is characterized in that the flat elements 7 are long strips or foils or a comparable nonwoven material, the width is smaller is as the grid internal dimension and of which in each case one in the longitudinal direction of the grille between two adjacent longitudinally extending lattice structure threads 2; 3 is integrated.
  • the flat elements 7 can be introduced into the textile grid in various ways.
  • Films or comparable nonwoven material in the width direction relative to the material of the lattice structural yarns 2,3 in the same direction have the greater shrinkage behavior.
  • This variant offers the advantage that, in a downstream coating and heating process, the shrinkage behavior of the flat elements in the transverse direction without further measures leads to the fact that the grating flanks form out.
  • the excess length of the flat elements 7 is achieved by pushing them into the production process at a predetermined conveying speed, so that the excess length of the flat elements 7 is proportional to a feed rate of the feed line, which is higher than the speed of the lattice structure threads laid in this direction Flat elements is, so corresponds to the excess of the differential speed between the speed of the flat elements 7 and the speed of the lattice structure threads.
  • Another possibility for producing the excess length of the flat elements results from the fact that the lattice structure threads in the direction of laying of the flat elements 7 have a predetermined shrinkage behavior and that after the Laying and the production of the finished textile grid, the excess length of the flat elements 7 is proportional to a temperature after the laying of the flat elements 7 shrinkage of the laid in this direction shrinkable lattice structural threads.
  • the lattice structure threads 3 extending in the transverse direction are of strong shrinkage behavior compared with the flat elements 7 laid in the same direction.
  • the textile grid according to FIG. 5 is here more shrinkable in the transverse direction than in the longitudinal direction.
  • the flat elements are formed in contrast to the embodiment of Figures 1 to 3 from a flattened sliver, which are introduced several times in the respective lattice structure threads.
  • the flat elements are formed by a film, ribbon or similar nonwoven material whose width in the finished textile grid is smaller than the grid internal dimension.
  • this flat material can be pulled off a roll 20 whose width is practically smaller than the width of the finished textile grid.
  • the width of the roll 20 of the flat material corresponds to the width of the finished textile grid minus the running in the same direction total width of all lattice structural threads.
  • the flat material withdrawn from the roll must then be cut into individual strips via corresponding longitudinal cutting devices 21, which are then to be inserted into the respective inner grid dimension.
  • the direction-giving lattice structure threads 2, 3 can be designed in the form of a fabric or a lamina bound at the intersections 4.
  • the lattice structure threads 2, 3 of at least one of the two groups of a shrinkable material here the lattice structure threads with the reference numeral 12th
  • the shrinkable material may preferably be polymeric plastic material, for example polyester, polyamide or comparable plastic material.
  • FIG. 4 also shows, in relation to the representation 4a, which gives a view from above onto the ground, before the textile grid is laid on it, that the textile grid 1 according to the invention is in excellent condition to the contour of the ground consequences.
  • the lying between the lattice structural yarns 2 flat elements 7 are full on the ground, which, according to Fig.4a, for example, may consist of a milled tar ground.
