Description

Die Erfindung betrifft einen Zuggurt aus einer hydraulisch abbindenden Masse, der bei Belastung Zugspannungen in einer vorbestimmten Richtung unterliegt und eine Faserbewehrung hat, zu der in die Zugzone eingelegte, zu der Richtung der Zugspannungen parallele Faserbündel sowie in der Zugzone befindliche Kurzfasern gehören. (siehe AT-C-344966).The invention relates to a tension belt made of a hydraulically setting mass, which is subject to tensile stresses in a predetermined direction when loaded and has a fiber reinforcement, to which fiber bundles inserted into the tensile zone, parallel to the direction of the tensile stresses, and short fibers located in the tensile zone belong. (see AT-C-344966).

Platten aus hydraulisch abbindenden Massen sind auf breiter Basis als Baukörper aller Art in Form von Asbestzementplatten und Faserbetonplatten bekannt und wegen ihrer guten Eigenschaften geschätzt. Die Faserbewehrung liegt hier in Form von Kurzfasern vor. Zur Erzielung einer ausreichenden Festigkeit ist eine verhältnismässsig grosse Menge an Fasern erforderlich.Panels made of hydraulically setting compounds are widely known as structures of all kinds in the form of asbestos cement panels and fiber concrete panels and are valued for their good properties. The fiber reinforcement is in the form of short fibers. A relatively large amount of fibers is required to achieve sufficient strength.

Aufgabe der Erfindung ist es, einen Zuggurt aus hydraulisch abbindenden Massen zu schaffen, der mit einem Minimum an Fasern einem plattenförmigen Baukörper eine ausreichende Festigkeit, insbesondere Zugfestigkeit verleiht, die derjenigen der bekannten Asbest- und Faserbetonplatten zumindest gleich ist oder die übertrifft.The object of the invention is to provide a tension belt made of hydraulically setting compositions which, with a minimum of fibers, gives a plate-shaped structure sufficient strength, in particular tensile strength, which is at least the same as that of the known asbestos and fiber concrete slabs or which surpasses them.

Diese Aufgabe wird gelöst durch einen Zuggurt der genannten Art, der dadurch gekennzeichnet ist, daß die hydraulisch abbindenden Masse schwindarm ist und daß die Faserbündel in die Masse hoher Dehnfähigkeit eingelegt sind, die mit Kurzfasern bewehrt ist und die Faserbündel allseits umgibt.This object is achieved by a tension belt of the type mentioned, which is characterized in that the hydraulically setting mass is low-shrinkage and that the fiber bundles are inserted into the mass of high elasticity, which is reinforced with short fibers and surrounds the fiber bundles on all sides.

Zweckmässige Weiterbildungen des Zuggurts sind in den Unteransprüchen gekennzeichnet.Appropriate further developments of the tension belt are characterized in the subclaims.

Zuggurte dieser Art bilden die Aussenschichten von Platten bzw. plattenförrmigen Körpern und verleihen diesen eine hohe Zugfestigkeit, Schlagfestigkeit und Tragfähigkeit. Ein wesentlicher Vorteil der Verwendung solcher Zuggurte besteht u.a. darin, dass weitaus weniger Fasern zur Bewehrung benötigt werden als bei herkömmlichen Faserbetonplatten mit Kurzfasern, um gleiche Eigenschaften, insbesondere gleiche Tragfähigkeit zu erreichen. Dies kann bei mit Zuggurten versehenen Platten schon mit einem auf weniger als die Hälfte verringerten Fasergehalt erzielt werden.Tension belts of this type form the outer layers of plates or plate-shaped bodies and give them high tensile strength, impact resistance and load capacity. One of the main advantages of using such tension belts is: in that far fewer fibers are required for reinforcement than with conventional fiber reinforced concrete slabs with short fibers in order to achieve the same properties, in particular the same load-bearing capacity. In the case of plates provided with tension belts, this can be achieved with a fiber content reduced to less than half.

Bei bekannten, mit künstlichen Kurzfasern bewehrten Platten, wird durchschnittlich ein Faseranteil von etwa 5% benötigt. Es wurde gefunden, dass bei mit erfindungsgemässen Zuggurten bewehrten Platten nur etwa 2,5% Fasern erforderlich sind, um die gleiche Tragfähigkeit und Schlagfestigkeit wie mit 5% Kurzfasern zu erzielen. Gegenüber Asbestzement, dessen Asbestanteil etwa 10% beträgt, ist die Einsparung noch wesentlich gravierender.In the case of known boards reinforced with artificial short fibers, an average fiber content of about 5% is required. It was found that only about 2.5% of fibers are required for panels reinforced with tension belts according to the invention in order to achieve the same load-bearing capacity and impact resistance as with 5% short fibers. Compared to asbestos cement, whose asbestos content is around 10%, the savings are even more serious.

Bei Verwendung von erfindungsgemässen Zuggurten wird bei Platten aus hydraulisch abbindenden Massen praktisch die statische Wirkung eines Sandwichs erreicht. Dabei übernehmen die durch die Zuggurte bewehrten Aussenschichten die Last und der Kern hat die Aufgabe, Schubkräfte zu übertragen. Die Zuggurte führen zu einem hohen Arbeitsvermögen und es erfordert viel Kraft, bis Bruch eintritt.When using tension belts according to the invention, the static effect of a sandwich is practically achieved in the case of plates made of hydraulically setting compositions. The outer layers reinforced by the tension belts take over the load and the core has the task of transmitting thrust forces. The tension belts lead to a high work capacity and it takes a lot of force to break.

Mit Hilfe solchere Zuggurte ist es möglich, verhältnismässig dünne stark beanspruchbare Platten aus hydraulisch abbindenden Massen, beispielsweise Platten mit einer Stärke von 10 mm, herzustellen. Der Zuggurt ist jeweils als Aussenschicht der Platte vorgesehen und die aus in Kraftrichtung orientierten Faserbündeln bestehende Hauptbewehrung befindet sich wenig unterhalb der Oberfläche eingebettet in das Material der hydraulisch abbindenden Masse.With the aid of such tension belts, it is possible to produce relatively thin, heavy-duty panels from hydraulically setting compositions, for example panels with a thickness of 10 mm. The tension belt is provided as the outer layer of the plate and the main reinforcement consisting of fiber bundles oriented in the direction of the force is embedded a little below the surface in the material of the hydraulically setting mass.

Die Faserbündel, insbesondere aus Glas, alkaliwiderstandsfähigem Glas und/oder Kunststoff können in der Fläche einlagig oder mehrlagig eingebettet werden, wobei die Lagen parallel oder im Winkel zueinander verlegt sein können, mit einer bevorzugten Winkellage von 90°.The fiber bundles, in particular made of glass, alkali-resistant glass and / or plastic, can be embedded in the surface in one or more layers, the layers being able to be laid parallel or at an angle to one another, with a preferred angular position of 90 °.

Eine besonders zweckmässige Ausführungsform sind Zuggurte, deren endlose Faserbündel vor dem Verlegen getränkt worden sind. Solche getränkten Faserbündel bringen mehrere Vorteile. So wird das Absaugen von Wasser verhindert, die Faserbündel werden besser verankert, es wird eine bessere Langzeitbeständigkeit erreicht, da eine Versprödung hinausgezögert oder sogar verhindert wird, und schliesslich ist die Verlegung getränkter Fasern einfacher.A particularly useful embodiment is tension belts, the endless fiber bundles of which have been soaked before laying. Such impregnated fiber bundles have several advantages. This prevents water from being sucked off, the fiber bundles are anchored better, better long-term durability is achieved because embrittlement is delayed or even prevented, and finally it is easier to lay soaked fibers.

Mit erfindungsgemässen Zuggurten lassen sich äusserst stabile zug- und schlagfeste Körper aus hydraulisch abbindenden Massen herstellen.With tension belts according to the invention, extremely stable tensile and impact-resistant bodies can be produced from hydraulically setting compositions.

Bei ebenen Platten sind die Zuggurte faserbewehrte Aussenschichten, die durch einen massiven Kern bzw. eine Kernmasse oder durch aus einer solchen Kernmasse bestehenden Stege miteinander schubfest verbunden sind. Die Materialien, aus denen die faserbewehrten Zuggurte und der Kern bzw. die Stege bestehen, können gleich oder verschieden sein. Wesentlich ist, dass an den Grenzschichten zwischen den Zuggurten und dem Kern bzw. den Stegen eine ausreichende schubfeste Bindung vorliegt.In the case of flat panels, the tensioning straps are fiber-reinforced outer layers which are connected to one another in a shear-resistant manner by a solid core or a core mass or by webs consisting of such a core mass. The materials from which the fiber-reinforced tension belts and the core or the webs consist can be the same or different. It is essential that there is sufficient shear-resistant binding at the boundary layers between the tension belts and the core or the webs.

Bei Well- und Trapezplatten befinden sich die Zuggurte in den oberen und unteren Begrenzungsflächen.For corrugated and trapezoidal sheets, the tension belts are located in the upper and lower boundary surfaces.

Sowohl ebene als auch wellige, mit erfindungsgemässen Zuggurten bewehrte Platten können zu verschiedenen Elementen, wie Rohre, Schalen und andere beliebige Raumkörper, geformt sein.Both flat and corrugated panels reinforced with tension belts according to the invention can be formed into various elements, such as pipes, shells and any other spatial body.

Das Verlegen und Einbetten der endlosen Fasern oder Faserbündel kann durch Einbau dünner Vliese, Gewebe oder Gelege erleichtert werden. Diese bilden noch eine zusätzliche Bewehrung und ermöglichen auch eine Vorfertigung der Zuggurtbewehrung.The laying and embedding of the endless fibers or fiber bundles can be facilitated by installing thin fleeces, fabrics or scrims. These form an additional reinforcement and also enable prefabrication of the tension belt reinforcement.
