Description

Die Erfindung betrifft den in der Spannbetontechnik, Abspanntechnik oder zur Armierung von Beton verwendeten Spannstahl, Spanndraht oder Armierungsstahl.The invention relates to that in prestressed concrete technology, guy technology or prestressing steel, tension wire or reinforcing steel used to reinforce concrete.

Im Spannbetonbau wird Spannstahl beispielsweise zur Vorspannung von Trägern, Platten, Schalen oder Gewerken aus Beton für den Bau von Brücken, Hallen, Fundamenten sowie für den allgemeinen Hochbau verwendet.In prestressed concrete construction, prestressing steel is used, for example, for prestressing Beams, plates, shells or trades made of concrete for the construction of Bridges, halls, foundations and used for general building construction.

Im Stand der Technik ist es bekannt, den Spannstahl, der in Form eines Einzelstabes, in Form von Einzeldrähten oder auch in Form von Litzen vorliegen kann, in ein Hüllrohr bzw. Spannkanal einzubringen.It is known in the prior art to use prestressing steel in the form of a Single rod, in the form of individual wires or in the form of strands can be inserted into a cladding tube or tensioning channel.

Nach dem Vorspannen wird der Spannstahl durch Verpressen mit Injektionsmörtel gegen Korrosion geschützt.After prestressing, the prestressing steel is injected with grout protected against corrosion.

Durch den festen Verbund sind Nachspannarbeiten und eventueller Austausch der Spannstähle nicht möglich bzw. nur unter sehr hohem Aufwand.Due to the firm bond, re-tensioning work and possible exchange are possible prestressing steels not possible or only with great effort.

Aufgabe der Erfindung ist es, einen Spannstahl oder Armierungsstahl vorzusehen, der langlebig ist und ein Auswechseln auf einfache Weise ermöglicht.The object of the invention is to provide a prestressing steel or reinforcing steel, which is durable and enables replacement in a simple manner.

Gelöst wird die Aufgabe erfindungsgemäß durch Vorsehen eines Spann- bzw. Armierungsstahls mit den Merkmalen des Hauptanspruchs 1, dessen vorteilhafte Weiterbildungen in den Unteransprüchen angegeben sind. According to the invention, the object is achieved by providing a clamping or reinforcing steel with the features of main claim 1, the advantageous developments are specified in the subclaims.

So besteht der erfindungswesentliche Gedanke darin, den Spann- oder Armierungsstahl mit mindestens zwei Ummantelungen zu versehen, um eine Relativbewegung zwischen zumindest zwei Ummantelungen ohne größere Krafteinleitung zu ermöglichen. Die beiden relativ zueinander verschiebbaren Ummantelungen weisen keinen zwischenliegenden Verbund auf, so daß sie sich ohne größere Gewalteinleitung verschieben lassen.So the idea essential to the invention is the tension or Reinforcing steel with at least two jackets to a relative movement between at least two jackets without major To allow force introduction. The two slidable relative to each other Sheaths have no intermediate bond on so that they can be moved without major violence.

Unter Spann- oder Armierungsstahl ist hierbei jede marktübliche Form zur Abspannung oder Armierung von Beton zu verstehen. Damit sind sowohl Spannstahldraht, Spannstahllitzen oder Armiergestänge mit einbezogen. Ein Versehen des Spannstahls mit einer Ummantelung bedeutet dabei, daß der Spannstahl im Querschnitt über seinen Außenumfang von der Ummantelung im wesentlichen umschlossen ist. Der Spannstahl ist diesbezüglich nicht an eine bestimmte Querschnittsform gebunden und kann rund, ovalförmig oder andersartig mit beispielsweise einer Profilierung ausgebildet sein.Any shape customary on the market is used for prestressing or reinforcing steel Understanding bracing or reinforcement of concrete. So that are both Prestressing steel wire, prestressing steel strands or reinforcing rods included. On Providing the prestressing steel with a jacket means that the Prestressing steel in cross-section over its outer circumference from the casing is essentially enclosed. The prestressing steel is in this regard not tied to a specific cross-sectional shape and can be round, oval-shaped or formed differently with, for example, a profiling his.

Durch das Vorsehen eines Spannstahls mit beispielsweise zwei Ummantelungen, d.h. einer äußeren Ummantelung und einer inneren Ummantelung, die eine Relativbewegung zueinander zulassen, kann der Spannstahl leichter ausgewechselt werden. Da ein Verbund zum einen lediglich zwischen der äußeren Ummantelung und dem Einpreßmörtel und zum anderen zwischen der inneren Ummantelung und dem Stahl vorliegt, kann aufgrund der möglichen Relativbewegung zwischen den Ummantelungen der Spannstahl zusammen mit der inneren Ummantelung leicht aus der äußeren Ummantelung und damit aus dem Hüllrohr gezogen werden. Mit anderen Worten bilden die zwei zueinander verschiebbaren Ummantelungen jeweils Rohre, wobei sich das eine innere Rohr in dem anderen äußeren Rohr verschieben läßt. Nach Entfernen des Spannstahls mit dem inneren Rohr kann ein neuer Spannstahl mit innerem Rohr eingeschoben werden. By providing a prestressing steel with, for example, two jackets, i.e. an outer casing and an inner casing, the prestressing steel can allow a relative movement to each other be replaced more easily. Because a network on the one hand only between the outer casing and the grout and the other between the inner casing and the steel can be due to the possible relative movement between the sheathing of the prestressing steel together with the inner jacket easily from the outer Jacket and thus pulled out of the cladding tube. With others Words form the two mutually displaceable casings Pipes, with one inner pipe moving in the other outer pipe leaves. After removing the prestressing steel with the inner tube a new prestressing steel with an inner tube can be inserted.

Gemäß einer vorteilhaften Ausführungsform wird zwischen dem Spannstahl und der ersten Ummantelung eine Korrosionsschutzschicht auf die Metalloberfläche des Spannstahls aufgebracht. Das Benetzen des Spannstahls mit Korrosionsschutz kann dabei durch Tauchen, Streichen, Gießen, Rollen oder Sprühen erfolgen.According to an advantageous embodiment, between the prestressing steel and the first casing has a corrosion protection layer on the metal surface of prestressing steel applied. Wetting the prestressing steel with corrosion protection can be done by dipping, painting, pouring, rolling or spraying.

Auf diesen Korrosionsschutz wird sodann die erste Ummantelung aufgebracht. Diese Ummantelung ist vorteilhafterweise aus thermoplastischem Kunststoff, wie beispielsweise Polyethylen oder Polypropylen. Der Kunststoffmantel kann in Form eines nahtlosen Schlauchs durch Extrudieren unter Verwendung einer ringförmigen Düse, durch die der Spannstahl hindurchgeführt wird, aufgebracht oder die Kunststoffummantelung in Form eines Folienbandes schraubenlinienförmig um den Spannstahlkern gewickelt werden. Der Mantel kann als Rohr oder mit Litzenkontur ausgeführt werden.The first casing is then applied to this corrosion protection. This sheathing is advantageously made of thermoplastic Plastic, such as polyethylene or polypropylene. The plastic jacket can be extruded in the form of a seamless tube using an annular nozzle through which the prestressing steel passes is applied or the plastic coating in the form of a foil strip helically around the prestressing steel core be wrapped. The sheath can be designed as a tube or with a strand contour become.

Auf die bereits aufgebrachte Ummantelung wird darauffolgend eine weitere, im vorliegenden Fall zweite Ummantelung aufgebracht. Das erfolgt derart, daß zwischen der bereits aufgebrachten ersten Ummantelung und der zweiten Ummantelung kein Verbund entsteht. So ist darauf zu achten, daß die beiden Ummantelungen nicht miteinander verkleben können. Demgemäß muß die erste Ummantelung vor dem Aufbringen der zweiten Ummantelung getrocknet bzw. ausgehärtet sein. Die zweite, äußere Ummantelung kann dabei wiederum aus einem thermoplastischen Kunststoff bestehen und kann rohrförmig oder wendelförmig entsprechend der ersteren Ummantelung aufgebracht werden.A further, in the present case applied a second casing. This is done in such a way that between the already applied first casing and the second sheathing does not create a bond. It is important to ensure that the two jackets cannot stick together. Accordingly, must the first casing before applying the second casing be dried or cured. The second, outer casing can in turn consist of a thermoplastic and can be tubular or helical according to the former casing be applied.

Um eine Relativbewegung zwischen den aufgebrachten Ummantelungen zu verbessern, ist in einer vorteilhaften Ausführungsform der Erfindung zwischen diesen Ummantelungen eine Gleitschicht vorgesehen. Diese kann vor dem Vorsehen der äußeren Ummantelung auf den Außenumfang der ersten Ummantelung aufgesprüht, aufgestrichen, oder durch Eintauchen in diese angebracht werden.To a relative movement between the applied sheaths too improve, is in an advantageous embodiment of the invention between a sliding layer is provided for these casings. This can be done before the provision of the outer jacket on the outer circumference of the first Jacket sprayed on, spread on, or by immersion in it be attached.

Als Basis für das Gleitmittel eignet sich Wachs, Fett sowie aber auch andere Schmiermittel.Wax, grease and others are suitable as the basis for the lubricant Lubricant.

Im folgenden wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels des näheren erläutert.The following is based on an embodiment shown in the drawing explained in more detail.

In der Zeichnung zeigen:

Fig. 2
2 shows a cross section of the prestressing steel strand according to FIG. 1.

Die Figur zeigt eine Ausführungsform der Erfindung mit insgesamt zwei Ummantelungen einer Spannstahllitze 1. Die Spannstahllitze 1 weist sieben Litzenadern 3 auf. Auf die Litzenadern 3 ist eine Korrosionsschutzschicht 5 aufgebracht. Die erste Ummantelung 7 ist durch eine auf die Spannstahllitze aufgebrachte Polyethylenschicht vorgesehen, die einen Mantel in Form eines Rohres bildet. Die erste Ummantelung 7 bildet dabei zusammen mit der Spannstahllitze einen festen Verbund. Auf diese, erste Ummantelung 7 ist eine Gleitschicht 9 in Form von Schmierfett aufgebracht. Sie bildet das Zwischenglied zwischen der ersten Ummantelung 7 und der auf der Gleitschicht aufgebrachten zweiten Ummantelung 11.The figure shows an embodiment of the invention with a total of two Sheathing of a prestressing steel strand 1. The prestressing steel strand 1 has seven Strand wires 3 on. A corrosion protection layer 5 is on the stranded wires 3 applied. The first sheath 7 is through a on the prestressing steel strand Applied polyethylene layer is provided, which is a jacket in shape of a pipe. The first casing 7 forms together with the prestressing steel strand a firm bond. On this, first casing 7 a sliding layer 9 is applied in the form of grease. It forms that Intermediate link between the first casing 7 and that on the sliding layer applied second casing 11.

Damit ist es möglich, die Spannstahllitze 1 zusammen mit der ersten Ummantelung 7 in dem Außenrohr, d.h. der äußeren Ummantelung 11 zu verschieben. Ein Auswechseln der Spannstahllitze in dem Betonwerk ist dadurch vereinfacht, da ein Verbund lediglich zwischen dem Betonwerk, d.h. dem Einpreßmörtel in dem Hüllrohr und der äußeren Ummantelung sowie zwischen der inneren, ersten Ummantelung 7 und der Spannstahllitze 1, nicht jedoch zwischen den Ummantelungen 7, 11 selbst gebildet ist und sich die Spannstahllitze damit leicht aus dem Betonwerk bzw. dem Hüllrohr herausziehen läßt.This makes it possible to use the prestressing steel strand 1 together with the first Jacket 7 in the outer tube, i.e. the outer casing 11 to move. There is a replacement of the prestressing steel strand in the concrete plant simplified because a bond only between the concrete plant, i.e. the grout in the cladding tube and the outer casing and between the inner, first casing 7 and the prestressing steel strand 1, not however is formed between the sheaths 7, 11 and itself Use this to pull the prestressing steel wire slightly out of the concrete plant or the cladding tube leaves.
