Definitions

  • the invention relates to a wide-mesh fabric, in which several warp threads composed of warp strands and several Wefts composing weft bundles clear Limiting mesh, where at the intersection of the right angle mutually extending Kettfadenbündel and weft bundles the warp threads are interwoven with the wefts.
  • Mesh fabric of this type which - when used with a polymeric plastic impregnated or coated - in particular for reinforcing bitumen-bound Road surfaces or for strengthening cement or gypsum bound Mortar layers or as a geogrid for reinforcing soil application find are known from DE 20 00 937; 31 20 661; 31 36 026; 41 23 055 and 199 62 441.
  • the warp threads and the weft threads are preferably made of multifilaments Synthetic yarns of high tensile strength, in particular of aramid, polyester or like. Glass filament yarns may also be used.
  • the warp thread bundles and the weft bundles settle together at least four threads.
  • the Kettfadenbündel As a means which the Kettfadenbündel, the weft bundles and their Wrapped crossing points and thus fixed the mesh and against can protect chemical and mechanical stress, depending on the Intended use a PVC plastisol, a latex dispersion or dispersions from bitumen, acrylates or corresponding soft plastics as well Be mixtures of it.
  • the invention has for its object to provide a mesh fabric at the webtechnisch the mesh fabric is given a larger volume and when used as a geogrid better teeth with the to be reinforced Ground is reached.
  • the different length of the weft threads or warp threads per stitch can be produced by using weft threads or warp threads come, for example, in a heat treatment different shrink or stretch differently.
  • the warp thread bundles are in a first Warp group and a second warp group divided and the first Warp thread group crosses the second warp thread group of the same warp thread bundle in the manner of a half-turn per stitch once. This is the first warp thread always at the top and the second warp thread always at the bottom. At the intersections of warp and weft threads are the threads individually or in groups interwoven.
  • the mesh fabric according to the invention with protruding from the plane of the fabric Loops are particularly advantageous for many applications. It Not only will a better mesh with a soil to be reinforced achieved, but the mesh fabric according to the invention is also advantageous for Reinforcement of hardenable masses and products, eg. B. screeds and gypsum Concrete products, or as a carrier web in the production of bonding or curing products made of plastic, gypsum or concrete mortar, which are sprayed or molded onto the carrier fabric, so that the Loops protrude into the hardened products, and those over the Carrier fabric remain connected to each other. Furthermore, with the above Looped grid mat suitable, the supporting part of a drainage mat to build. Furthermore, it is possible to follow from the plane of the tissue up, down or up and down protruding loops parts be attached, for. As machines, or are inserted through, e.g. Steel reinforcements or drainage tubes.
  • the mesh fabric according to the invention is suitable for erosion protection, as anti-slip mat or as snow brake.
  • the covered with an elastic plastic layer mesh fabric with protruding loops has a very large stiction.
  • the large-mesh fabric 1 will consist of several Warp threads 2 composed of warp strands 3 and several Wefts 4 composed weft bundles 5 formed.
  • the Kettfadenbündel 3 and the weft bundles 5 enclose rectangular or square grid openings or meshes 6.
  • a part 4 'of the weft threads 4 are per stitch 6 longer than another part of the weft threads 4, so that the longer wefts form bulges or open loops 7, the protrude large part up and down from the plane of the mesh fabric 1.
  • a large mesh fabric 1 is shown, in which the warp thread bundles 3, for example, eight warp threads 2 and eight weft bundles Weft threads 4,4 'have.
  • the warp thread bundles 3 are divided into a first warp thread group 3 'and a second warp thread group 3 ". These two warp thread groups 3 'and 3" are on the crossing points 8 with the weft threads 4 of the weft bundles. 5 woven. Between two weft bundles 5, i. per stitch 6, crossed a warp thread group 3 'in each case the other warp thread group 3 "of a warp thread bundle 3 in the manner of a half-turn.
  • the interweaving at the intersections 8 takes place in such a way that a first Part of the weft threads 4 of a weft bundle 5 on the warp threads 2 of the first warp thread group 3 'and a second part 4' of the weft threads a weft bundle 5 under the warp threads 2 of the first warp thread group 3 'and over the warp threads 2 of the second warp thread group 3 " each odd-numbered weft thread runs over the first warp thread group 3 ' and under the second warp group 3 ", while each even weft under the first warp thread group 3 'and then over the second warp thread group 3 "of the warp thread bundle 3 runs.
  • the zigzags move at the intersections 8 extending warp thread groups 3 'and 3 "closer together when on the Kettfadenbiindel 3 a tensile force is applied. This push the inner edges of the warp thread groups 3 'and 3 "slightly above each other, so that a Part of the weft threads at the intersections 8 go through a longer path must as the other part of the weft bundle. 5
