Abstract

Individual yarns (2 or 4) of a yarn bundle (3 or 5) in one mesh (6) are longer than other yarns of the same bundle. The longer yarns (4') run meanderingly and form at least one open loop or a bulge (7). The open loops protrude upwards and downwards from the fabric plane and the longer yarns are 15-25% longer than the other yarns of the same bundle. An Independent claim is made for manufacturing the lattice.

Description

Beschreibung:Description:
Gittergewebemesh
Die Erfindung bezieht sich auf ein weitmaschiges Gittergewebe, bei dem aus mehreren Kettfäden sich zusammensetzende Kettfadenbündel und aus mehreren Schußfäden sich zusammensetzende Schußfadenbündel die lichten Maschen umgrenzen, wobei an den Kreuzungsstellen der rechtwinklig zueinander verlaufenden Kettfadenbündel und Schußfadenbündel die Kettfä- den mit den Schußfäden verwebt sind.The invention relates to a wide-mesh fabric in which warp thread bundles composed of a plurality of warp threads and weft bundles composed of a plurality of weft threads surround the open stitches, wherein the warp threads are interwoven with the weft threads at the intersections of the warp thread bundles and weft thread bundles extending at right angles.
Mit "Masche" sind in dieser Beschreibung die von dem Kettfadenbündel und Schußfadenbündel gebildeten rechteckigen oder quadratischen Gitteröffnungen bezeichnet."Mesh" in this specification refers to the rectangular or square grid openings formed by the warp bundle and weft bundles.
Gittergewebe dieser Art, die - wenn sie mit einem polymeren Kunststoff imprägniert oder beschichtet sind - insbesondere zum Bewehren von bitumengebundenen Straßendecken oder zum Armieren zement- oder gipsgebundener Mörtelschichten oder als Geogitter zum Bewehren von Böden Anwendung finden, sind bekannt aus den DE 20 00 937; 31 20 661 ; 31 36 026; 41 23 055 und 199 62 441.Lattice fabrics of this type, which - when they are impregnated or coated with a polymeric plastic - in particular for reinforcing bitumen-bound road surfaces or for reinforcing cement or gypsum bonded mortar layers or as geogrids for reinforcing soil application, are known from DE 20 00 937; 31 20 661; 31 36 026; 41 23 055 and 199 62 441.
Die Kettfäden und die Schußfäden bestehen vorzugsweise aus multifilen Synthetikgarnen hoher Zugfestigkeit, insbesondere aus Aramid, Polyester oder dergleichen. Es können auch Glasfilamentgarne zur Anwendung kommen.The warp threads and the weft threads are preferably made of multifilament synthetic yarns of high tensile strength, in particular of aramid, polyester or the like. Glass filament yarns may also be used.
Die Kettfadenbündel und die Schußfadenbündel setzen sich zusammen aus mindestens vier Fäden.The warp strands and the weft bundles are composed of at least four threads.
Als Mittel, welches die Kettfadenbündel, die Schußfadenbündel und deren Kreuzungsstellen umhüllt und damit das Gittergewebe fixiert und gegen chemische und mechanische Beanspruchung schützt, kann je nach dem Verwendungszweck ein PVC-Plastisol, eine Latex-Dispersion oder Dispersionen aus Bitumen, Acrylaten oder entsprechenden Weichkunststoffen sowie Mischlingen davon sein. Unter Gittergewebe sind auch solche Fadengelege zu verstehen, bei denen die Kettfäden und die Schußfäden an den Kreuzungsstellen nicht miteinander verwebt sind, sondern durch andere Techniken, insbesondere durch Rascheltechnik oder auch durch Verkleben oder Verschweißen, miteinander verbun- den sind.As a means, which envelops the warp strands, the weft bundles and their intersection points and thus protects the mesh and protects against chemical and mechanical stress, depending on the intended use, a PVC plastisol, a latex dispersion or dispersions of bitumen, acrylates or corresponding soft plastics and Be of it. Mesh fabrics also include those scrims in which the warp threads and the weft threads are not interwoven at the points of intersection, but are connected to one another by other techniques, in particular by raschel technology or by gluing or welding.
Der Erfindung liegt die Aufgabe zugrunde, ein Gittergewebe zu schaffen, bei dem webtechnisch dem Gittergewebe ein größeres Volumen gegeben wird und bei Verwendung als Geogitter eine bessere Verzahnung mit dem zu bewehren- den Boden erreicht wird.The invention has for its object to provide a mesh fabric, in the weaving the mesh fabric, a larger volume is given and when used as a geogrid better teeth with the soil to be reinforced is achieved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß einzelne Fäden eines Fadenbündels je Masche länger sind als die lichte Weite der Masche und länger sind als andere Fäden des gleichen Fadenbündels, wobei die längeren Fäden wellenförmig verlaufen und je Masche mindestens eine offene Schlinge oder Ausbauchung bilden.This object is achieved in that individual threads of a bundle of fibers per stitch are longer than the inside width of the mesh and are longer than other threads of the same bundle of fibers, the longer threads wavy and each stitch form at least one open loop or bulge.
Dadurch, daß ein Teil der Schuß- oder Kettfäden innerhalb der lichten Weite einer Masche länger sind als ein zweiter Teil der Schuß- oder Kettfäden des gleichen Fadenbündels, bilden die längeren Fäden je Masche Ausbauchungen oder offene Schlingen, die zum größeren Teil aus der Ebene des Gittergewebes nach oben oder unten ragen.The fact that a portion of the weft or warp threads are within the width of a mesh longer than a second part of the weft or warp threads of the same bundle of fibers, form the longer threads per stitch bulges or open loops, the greater part of the plane of the Mesh fabric up or down.
Damit die aus der Ebene des Gittergewebes herausragenden Ausbauchungen oder offene Schleifen nicht in die Ebene des Gittergewebes fallen, wird das Gittergewebe durch Imprägnierung oder durch Beschichtung mit einem polymeren Kunststoff versteift.In order for the bulges or open loops protruding from the plane of the mesh fabric not to fall into the plane of the mesh fabric, the mesh fabric is stiffened by impregnation or by coating with a polymeric plastic.
Die unterschiedliche Länge der Schußfäden oder Kettfäden je Masche kann dadurch erzeugt werden, daß Schußfäden oder Kettfäden zur Anwendung kommen, die beispielsweise bei einer Wärmebehandlung unterschiedlich schrumpfen oder sich unterschiedlich dehnen.The different lengths of the weft threads or warp threads per stitch can be produced by using weft threads or warp threads which, for example, shrink differently during heat treatment or stretch differently.
Bei Fadengelegen können einzelne Kettfäden eines Kettfadenbündels und/oder einzelne Schußfäden eines Schußfadenbündels je Masche aus der Gitterebene herausgehoben werden, bevor das Fadengelege die Stelle passiert, an der die Kettfäden mit den Schußfäden durch Rascheln, Kleben oder Schweißen verbunden werden.When yarn layers individual warp threads of a Kettfadenbündels and / or individual weft threads of a weft bundle per stitch can be lifted out of the lattice plane before the scrim passes the point at which the Warp threads are connected to the weft threads by rustling, gluing or welding.
Für Geotextilien ist ein Gittergewebe nach der DE 199 62 441 AI besonders vorteilhaft. Bei diesem Gittergewebe sind die Kettfadenbündel in eine erste Kettfadengruppe und eine zweite Kettfadengruppe geteilt und die erste Kettfadengruppe überkreuzt die zweite Kettfadengruppe des gleichen Kettfadenbündels nach Art eines Halbdrehers je Masche einmal. Dabei liegt die erste Kettfadengruppe stets oben und die zweite Kettfadengruppe stets unten. An den Kreuzungsstellen von Kettfäden und Schußfäden sind die Fäden einzeln oder gruppenweise miteinander verwebt.For geotextiles, a mesh fabric according to DE 199 62 441 A1 is particularly advantageous. In this mesh fabric, the warp thread bundles are divided into a first warp thread group and a second warp thread group, and the first warp thread group once crosses the second warp thread group of the same warp thread bundle in the manner of a half-turn per stitch. The first warp thread is always at the top and the second warp thread is always at the bottom. At the intersections of warp threads and weft threads, the threads are interwoven individually or in groups.
Durch eine stärkere Zugspannung in Kettrichtung wird erreicht, daß sich die Fäden der beiden im Zickzack verlaufenden und je Masche sich einmal kreuzenden Kettfadengruppen eines Bündels sich insbesondere im Bereich der Kreuzungsstellen enger zusammenschieben, was zur Folge hat, daß das Gittergewebe in Kettrichtung weniger nachgiebig ist und ohne weitere Dehnung große Kräfte aufzunehmen vermag und andererseits, daß ein Teil der Schußfäden die zueinander verschobenen Kettfadengruppen S-förmig um- schlingen, während der in Gegenphase verwebte Teil der Schußfäden die Kreuzungsstelle im wesentlichen gestreckt passieren, so daß dieser Teil der Schußfäden je Masche länger ist als der die lichte Weite der Maschen bestimmende Teil der kürzeren Fäden.By a stronger tension in the warp direction is achieved that the threads of the two running in a zigzag and each stitch once crossing warp thread groups of a bundle push closer together, in particular in the region of the intersections, with the result that the mesh fabric is less yielding in the warp direction and on the other hand, a portion of the weft yarns wrap around the warp yarn groups shifted in an S-shape while the interweaving part of the weft yarns pass substantially intersected so that this part of the weft yarns per stitch is longer is the part of the shorter threads which determines the clear width of the stitches.
Das Gittergewebe nach der Erfindung mit aus der Ebene des Gewebes herausragenden Schlaufen ist für zahlreiche Anwendungen besonders vorteilhaft. Es wird nicht nur eine bessere Verzahnung mit einem zu bewehrenden Erdboden erreicht, sondern das erfindungsgemäße Gittergewebe ist auch vorteilhaft zur Bewehrung erhärtbarer Massen und Erzeugnisse, z. B. Estriche sowie Gips- und Betonerzeugnisse, oder als Trägerbahn bei der Herstellung von abbindenden oder aushärtenden Erzeugnissen aus Kunststoff, Gips oder Betonmörtel, die auf das Trägergewebe aufgespritzt oder aufgeformt sind, so daß die Schlaufen in die erhärteten Erzeugnisse hinein ragen, und die über das Trägergewebe miteinander verbunden bleiben. Ferner ist die mit vorstehenden Schlaufen versehene Gittermatte geeignet, den tragenden Teil einer Draina- gematte zu bilden. Ferner können an den aus der Ebene des Gewebes nach oben, nach unten oder nach oben und unten herausragenden Schlaufen Teile befestigt werden, z. B. Faschinen, oder hindurchgesteckt werden, z.B. Stahlarmierungen oder Drainageröhrchen.The mesh fabric of the invention having loops protruding out of the plane of the fabric is particularly advantageous for many applications. It is not only better toothing achieved with a soil to be reinforced, but the mesh fabric according to the invention is also advantageous for reinforcement hardenable masses and products, eg. As screeds and gypsum and concrete products, or as a carrier web in the production of setting 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 over the carrier fabric remain connected to each other. Furthermore, the lattice mat provided with protruding loops is suitable for forming the load-bearing part of a drain mat. Further, at the loops protruding upward from the plane of the fabric, downwardly or upwardly and downwardly, there may be parts be attached, for. As Faschinen, or are put through, for example Stahlarmierungen or drainage tubes.
Schließlich eignet sich das erfindungsgemäße Gittergewebe zum Erosions- schütz, als Gleitschutzmatte oder als Schneebremse.Finally, the mesh fabric according to the invention is suitable for erosion protection, as anti-slip mat or as snow brake.
Das mit einer elastischen Kunststoffschicht umhüllte Gittergewebe mit vorragenden Schlaufen hat eine sehr große Haftreibung. Als Zwischenlage aufeinander liegender Steinblöcke einer Böschungsmauer kann dieses in der Böschung verankerte Gitter die Mauer mit der Böschung verbinden.The covered with an elastic plastic layer mesh fabric with protruding loops has a very large static friction. As an intermediate layer of stone blocks lying on a slope wall, this grid anchored in the embankment can connect the wall to the embankment.

Gittergewebes gemäß Fig. 3.Grid fabric according to FIG. 3.
Das großmaschige Gittergewebe 1 nach Fig. 1 und 2 wird aus mehreren Kettfäden 2 sich zusammensetzenden Kettfadenbündeln 3 und aus mehreren Schußfäden 4 sich zusammensetzenden Schußfadenbündeln 5 gebildet. Die Kettfadenbündel 3 und die Schußfadenbündel 5 umschließen rechteckige oder quadratische Gitteröffnungen oder Maschen 6. Ein Teil 4' der Schußfäden 4 sind je Masche 6 länger als ein anderer Teil der Schußfäden 4, so daß die längeren Schußfäden Ausbauchungen oder offene Schlingen 7 bilden, die zum großen Teil nach oben und unten aus der Ebene des Gittergewebes 1 herausragen.The large-meshed mesh fabric 1 according to FIGS. 1 and 2 is formed from a plurality of warp threads 2 composed of warp thread bundles 3 and from a plurality of weft threads 4 composed of weft bundles 5. The warp yarn bundles 3 and the weft bundles 5 enclose rectangular or square grid openings or meshes 6. A portion 4 'of the weft yarns 4 per stitch 6 are longer than another part of the weft yarns 4, so that the longer weft yarns form bulges or open loops 7, the protrude large part up and down from the plane of the mesh fabric 1.
Die Schußfäden 4,4' sind an den Kreuzungsstellen 8 einzeln oder gruppenweise mit den Kettfäden 2 der Kettfadcnbündel verwebt. Ferner ist das Gitterge- webe 1 mit seinen offenen Schlingen 7 durch Imprägnieren oder Beschichten mit einem polymeren Kunststoff versteift.The weft threads 4,4 'are individually or in groups interwoven with the warp threads 2 of the Kettfadcnbündel at the intersections. Furthermore, the grid woven fabric 1 with its open loops 7 stiffened by impregnation or coating with a polymeric plastic.
In Fig. 3 ist ein großflächiges Gittergewebe 1 dargestellt, bei dem die Kettfa- denbündel 3 beispielsweise acht Kettfäden 2 und die Schußfadenbündel acht Schußfäden 4,4' aufweisen.FIG. 3 shows a large mesh fabric 1 in which the warp yarn bundles 3 have, for example, eight warp yarns 2 and the weft yarn bundles eight weft yarns 4, 4 '.
Die Kettfadenbündel 3 sind geteilt in eine erste Kettfadengruppe 3' und eine zweite Kettfadengruppe 3". Diese beiden Kettfadengruppen 3' und 3" sind an den Kreuzungsstellen 8 mit den Schußfäden 4 der Schußfadenbündel 5 verwebt. Zwischen zwei Schußfadenbündeln 5, d.h. je Masche 6, überkreuzt eine Kettfadengruppe 3' jeweils die andere Kettfadengruppe 3" eines Kettfadenbündels 3 nach Art eines Halbdrehers.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 interwoven at the crossing points 8 with the weft threads 4 of the weft bundles 5. Between two weft bundles 5, i. per stitch 6, a warp thread group 3 'crosses the other warp thread group 3 "of a warp thread bundle 3 in the manner of a half-turn.
Die Verwebung an den Kreuzungsstellen 8 erfolgt in der Weise, daß ein erster Teil der Schußfäden 4 eines Schußfadenbündels 5 über die Kettfäden 2 der ersten Kettfadengruppe 3' verläuft und ein zweiter Teil 4' der Schußfäden eines Schußfadenbündels 5 unter die Kettfäden 2 der ersten Kettfadengruppe 3' und über die Kettfäden 2 der zweiten Kettfadengruppe 3" verläuft. Dabei verläuft jeder ungeradzahlige Schußfaden über die erste Kettfadengruppe 3' und unter die zweite Kettfadengruppe 3", während jeder geradzahlige Schußfaden unter die erste Kettfadengruppe 3' und dann über die zweite Kettfadengruppe 3" des Kettfadenbündels 3 verläuft.The interweaving at the intersections 8 takes place in such a manner that a first part of the weft threads 4 of a weft thread bundle 5 extends over the warp threads 2 of the first warp thread group 3 'and a second part 4' of the weft threads of a weft thread bundle 5 under the warp threads 2 of the first warp thread group 3 In this case, each odd-numbered weft thread passes over the first warp thread group 3 'and under the second warp thread group 3 ", while each even-numbered weft thread passes under the first warp thread group 3' and then over the second warp thread group 3". of the warp thread bundle 3 runs.
Durch starken Zug an den Kettfadenbündeln 3 strecken sich die im Zickzack verlaufenden Kettfadengruppen 3' und 3", so daß an den Kreuzungsstellen 8 ein Teil der Schußfäden - wie die Fig. 5 zeigt - S-förmig die Kettfadengruppen umschlingen, während ein anderer Teil der Schußfäden die Kreuzungsstelle 8 mir geringerem Längenverlust passiert.By strong train to the Kettfadenbündeln 3 extending in a zigzag Kettfadengruppen 3 'and 3 ", so that at the intersection of 8 a portion of the weft yarns - as shown in FIG. 5 - S-shaped loop around the Kettfadengruppen while another part of the Weft threads the crossing point 8 happened to me less loss of length.
Wie die Fig. 5 zeigt, schieben sich an den Kreuzungsstellen 8 die im Zickzack verlaufenden Kettfadengruppen 3' und 3" näher zusammen, wenn auf die Kettfadenbündel 3 eine Zugkraft ausgeübt wird. Dabei schieben sich die inneren Ränder der Kettfadengruppen 3' und 3" etwas übereinander, so daß ein Teil der Schußfäden an den Kreuzungsstellen 8 einen längeren Weg durchlaufen müssen als der andere Teil des Schtißfadenbiindels 5. Bezugszeichenliste:As shown in Fig. 5, at the crossing points 8, the warp thread groups 3 'and 3 "extending in a zigzag move closer together when a tensile force is exerted on the warp thread bundles 3. The inner edges of the warp thread groups 3' and 3" move slightly one above the other, so that a part of the weft threads at the intersections 8 have to go through a longer path than the other part of the Schtißfadenindelfels. 5 LIST OF REFERENCE NUMBERS
