Abstract
Description
Die Erfindung betrifft eine Verbundmatte zur Auskleidung von Betonwänden gemäß dem Oberbegriff des Patentanspruchs 1. The invention relates to a composite mat for lining concrete walls according to the preamble of
Derartige Verbundmatten werden zur Abdichtung von aus Beton gegossenen Strukturen insbesondere der Agrartechnik, z.B. Stallungen, Silos, Güllebehälter verwendet, damit Flüssigkeiten und Gase die Betonwände nicht angreifen können. Die synthetische Schutzfolie ist eine meist 0,5 bis 2,5 mm dicke Kunststofffolie, die vollständig wasserdicht und gasdicht ausgebildet ist und die gegen die Flüssigkeiten und Gase, mit denen sie in Kontakt tritt, chemisch beständig ist. Beispielsweise hat sich Polypropylen und Polyethylen zur Herstellung der Schutzfolie bewehrt. Such composite mats are used to seal concrete cast structures, in particular agricultural machinery, e.g. Stables, silos, manure tanks used so that liquids and gases can not attack the concrete walls. The synthetic protective film is usually a 0.5 to 2.5 mm thick plastic film, which is completely waterproof and gas-tight and which is chemically resistant to the liquids and gases with which it comes into contact. For example, polypropylene and polyethylene has been used to make the protective film.
Derartige Verbundmatten sind z.B. aus der Druckschrift
Das deutsche Gebrauchsmuster beschreibt eine derartige Verbundmatte, bei der zwischen der Textilschicht mit Schlingen und der Schutzfolie eine Schaumschicht aus synthetischem Material angeordnet ist, welche eine dämpfende Eigenschaft hat und die Kraftübertragung zwischen Beton und Schutzfolie abfedert. Die Schaumschicht kann mit der Textilschicht und mit der Schutzfolie vollflächig verklebt sein. The German utility model describes such a composite mat, in which between the textile layer with loops and the protective film, a foam layer of synthetic material is arranged, which has a damping property and absorbs the power transmission between concrete and protective film. The foam layer can be glued to the textile layer and the protective film over the entire surface.
Aufgabe der Erfindung ist es, eine kostengünstige Verbundmatte zu schaffen, welche eine vollflächige und feste Anbindung der Schutzfolie an dem Beton ermöglicht. The object of the invention is to provide an inexpensive composite mat, which allows a full-surface and fixed connection of the protective film to the concrete.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das textile Flächengebilde ein Abstandsgewirke ist, dessen Polfäden die Schlingen oder Schlaufen bilden. This object is achieved in that the fabric is a spacer fabric whose pile threads form the loops or loops.
Abstandsgewirke sind doppelflächige Textilien, bei denen in zwei zueinander im Wesentlichen parallelen Ebenen befindliche Warenflächen durch abstandshaltende Verbindungsfäden, sogenannte Polfäden, miteinander verbunden sind und auf Distanz gehalten werden. Abstandsgewirke sind Maschenwaren, die auf Doppelraschelmaschinen mit zwei Nadelbarren in einem Arbeitsgang hergestellt werden. Abstandsgewirke werden zu vielfältigen Zwecken verwendet, beispielsweise als Polstermaterial für Matratzen oder zur dämmenden Auskleidung von Wänden. Im vorliegenden Fall werden nicht die dämpfenden und luftdurchlässigen Eigenschaften eines Abstandsgewirkes verwendet. Vielmehr wird bei der vorgeschlagenen Verbundmatte die Tatsache berücksichtigt, dass die Polfäden des Abstandsgewirkes, die sich zwischen den zwei Warenflächen erstrecken, offen dreidimensionale Schlingen oder Schlaufen bilden, welche in den Beton eingebettet werden können und mit diesem verkrallen. Die Polfäden eines Abstandsgewirkes sind sehr viel gleichmäßiger verteilt, als die Schlingen oder Schlaufen eines handelsüblichen Schlingengewebes. Auf diese Weise wird eine Verbundmatte mit einem Abstandsgewirke über ihre gesamte Fläche sehr homogen mit der auszukleidenden Betonwand verbunden. Die Verwendung eines Abstandsgewirkes ist außerdem preislich vorteilhaft, da Abstandsgewirke in großen Mengen günstig maschinell herstellbar sind. Spacer fabrics are double-surface textiles in which goods areas located in two mutually substantially parallel planes are connected to one another by spacing connecting threads, so-called pile threads, and are kept at a distance. Spacer fabrics are knitwear made on double raschel machines with two needle bars in a single operation. Spacer fabrics are used for a variety of purposes, such as upholstery for mattresses or for insulating lining of walls. In the present case, the damping and air-permeable properties of a spacer knit are not used. Rather, in the proposed composite mat, the fact is taken into account that the pile threads of the spacer knit extending between the two fabric surfaces form open three-dimensional loops or loops which can be embedded in the concrete and dig into it. The pile threads of a knitted fabric are distributed much more evenly than the loops or loops of a commercially available loop fabric. In this way, a composite mat with a spacer knitted fabric over its entire surface is very homogeneously connected to the concrete wall to be lined. The use of a spacer knitted fabric is also advantageous in terms of cost, because spacer knitted fabrics can be produced by machine in large quantities.
In der Praxis kann die von der Schutzfolie entfernte zweite Warenfläche des Abstandsgewirkes eine offene Struktur aufweisen. Insbesondere kann die zweite Warenfläche im Wesentlichen aus zueinander parallel verlaufenden und im Abstand von mehreren Millimetern oder Zentimetern zueinander befindlichen Maschenreihen bestehen, die durch die Polfäden mit der ersten Warenfläche verbunden sind. In einer praktischen Ausführungsform weisen die Maschenreihen einen Abstand von 4 bis 8 mm zueinander auf. Die Polfäden, die sich zwischen der ersten und der zweiten Warenfläche erstrecken, können zu benachbarten Polfäden einen Abstand von mehreren Millimetern (3 bis 8 mm) aufweisen. Gleiches gilt für zusätzliche Fäden, die zwischen zwei benachbarten Maschenreihen der zweiten Warenfläche verlaufen. So ist es gewährleistet, dass der fließfähige Beton zuverlässig in die Zwischenräume zwischen den von den Polfäden gebildeten Schlingen oder Schlaufen der Verbundmatte eindringen kann und die Verbundmatte homogen und vollflächig an die Betonschicht gebunden ist. In practice, the second fabric surface of the spacer fabric removed from the protective film may have an open structure. In particular, the second fabric surface may essentially consist of mutually parallel stitches which are located at a distance of several millimeters or centimeters from each other and which are connected to the first fabric surface by the pile threads. In a practical embodiment, the courses have a distance of 4 to 8 mm from one another. The pile threads extending between the first and second fabric surfaces may be spaced several millimeters (3 to 8 mm) from adjacent pile threads. The same applies to additional threads that run between two adjacent courses of the second fabric area. Thus, it is ensured that the flowable concrete can reliably penetrate into the spaces between the loops or loops of the composite mat formed by the pile threads and the composite mat is homogeneously and fully bonded to the concrete layer.
Der Begriff "Schlingen oder Schlaufen" beschreibt jede geschlossene Anordnung von Fäden oder Fadengruppen, die fest mit der Schutzfolie verbunden sind und in die Betonschicht eingebettet werden können. The term "loops or loops" describes any closed arrangement of threads or groups of threads which are firmly connected to the protective film and can be embedded in the concrete layer.
In der Praxis kann die nahe der Schutzfolie liegende erste Warenfläche des Abstandsgewirkes eine dichte Struktur aufweisen. Mit anderen Worten können die Fäden des Abstandsgewirkes in der ersten Warenfläche feine und eng nebeneinander liegende Maschen bilden, welche eine vollflächige Verbindung mit der Schutzfolie eingehen. In practice, the first fabric surface of the spacer knit fabric located near the protective film may have a dense structure. In other words, the threads of the spacer knitted fabric can form fine and closely adjacent stitches in the first fabric surface, which form a full-surface connection with the protective film.
Die erste Warenfläche des Abstandsgewirkes kann durch ein Heißverbundverfahren mit der Schutzfolie verbunden werden. Dabei wird die erste Warenfläche gegen das erhitzte, noch nicht vollständig erstarrte Material der Schutzfolie gedrückt, sodass die Fäden dieser ersten Warenfläche an dem synthetischen Material der Schutzfolie anhaften. Die Fäden können zumindest teilweise in das synthetische Material der Schutzfolie eindringen. The first fabric surface of the spacer knitted fabric can be connected to the protective film by a hot-bonding process. In this case, the first product surface is pressed against the heated, not yet completely solidified material of the protective film, so that the threads of this first product surface adhere to the synthetic material of the protective film. The threads can at least partially penetrate into the synthetic material of the protective film.
Es ist auch möglich, zwischen der ersten Warenfläche des Abstandsgewirkes und der Schutzfolie mindestens eine Klebeverbindung anzuordnen, welche das Abstandsgewirke mit der Schutzfolie verbindet. It is also possible to arrange between the first fabric surface of the spacer knitted fabric and the protective film at least one adhesive bond, which connects the spacer knitted fabric with the protective film.
Ferner kann zwischen der ersten Warenfläche des Abstandsgewirkes und der Schutzfolie eine Dämpfungsschicht angeordnet werden, welche eine hohe Porosität und dämpfende Eigenschaften aufweist und welche die Kraftübertragung aus dem Beton auf die Schutzfolie abfedert. Diese Dämpfungsschicht kann beispielsweise eine dünne Schicht flexiblen Kunststoffschaums oder ein dünnes textiles Faservlies sein. Furthermore, a damping layer can be arranged between the first fabric surface of the spacer knitted fabric and the protective film, which has a high porosity and damping properties and which absorbs the force transmission from the concrete to the protective film. This damping layer can be, for example, a thin layer of flexible plastic foam or a thin textile non-woven fabric.
Die Dämpfungsschicht kann mit dem Abstandsgewirke und/oder mit der Schutzfolie vollflächig verklebt werden. Bei einem Verkleben der Schutzfolie kann diese zuvor derart behandelt sein, dass ihre Benetzbarkeit mit Klebstoff gesteigert ist. Beispielsweise eignet sich eine sogenannte Koronabehandlung der aus Kunststoff bestehenden Schutzfolie dazu, ihre Benetzbarkeit mit Klebstoff zu steigern. The damping layer can be glued to the spacer fabric and / or the protective film over the entire surface. If the protective film sticks together, it may be previously treated in such a way that its wettability with adhesive is increased. For example, a so-called corona treatment of the plastic protective film is suitable for increasing its wettability with adhesive.
In der Praxis können die Polfäden des Abstandsgewirkes aus monofilen Kunststofffäden bestehen. Monofile Fäden haben eine hohe Steifigkeit und Formbeständigkeit. Nach einem Zusammendrücken des Abstandsgewirkes der Verbundmatte, beispielsweise durch Andrücken an die Schutzfolie beim Herstellungsvorgang oder durch Aufbringen des Betons, entspannen sich die monofilen Polfäden, sodass sich das Abstandsgewirke wieder aufrichtet und sich der ursprüngliche Abstand zwischen den zwei Warenflächen des Abstandsgewirkes einstellt. Bei diesem Aufrichten nach dem Auftragen der Betonschicht dringen die Polfäden in die Betonschicht ein und stellen auf diese Weise ein zuverlässiges Verankern der Verbundmatte in der Betonschicht sicher. In practice, the pile threads of the spacer knitted fabric may consist of monofilament plastic threads. Monofilament threads have a high stiffness and dimensional stability. After compressing the spacer fabric of the composite mat, for example by pressing against the protective film in the manufacturing process or by applying the concrete, the monofilament pile threads relax, so that the spacer fabric straightens again and adjusts the original distance between the two fabric surfaces of the spacer fabric. During this erection after the application of the concrete layer, the pile threads penetrate into the concrete layer and thus ensure a reliable anchoring of the composite mat in the concrete layer.
Die Verbundmatte wird nachfolgend unter Bezugnahme auf die beigefügten Zeichnungen erläutert. The composite mat will be explained below with reference to the accompanying drawings.
