Abstract
Description
Die Erfindung betrifft einen Bewehrungsstab, der insbesondere zur wärmegedämmten Kraftübertragung zwischen zwei vorzugsweise aus Beton hergestellten Bauteilen dient, wobei der Bewehrungsstab aus faserverstärktem Kunststoff besteht. Bewehrungsstäbe werden beispielsweise zusammen mit einem von den Bewehrungsstäben durchquerten Isolierkörper in Bauteilfugen eingesetzt, um neben einer Kraftübertragung auch eine ausreichende Wärmedämmung zu erzielen.The invention relates to a reinforcement bar, in particular for thermal insulation Power transmission between two components, preferably made of concrete serves, the reinforcement bar consists of fiber-reinforced plastic. Reinforcement bars are, for example, together with one of the reinforcing bars traversed insulator used in component joints in addition to a power transmission to achieve adequate thermal insulation.
Bezüglich derartiger Kunststoffbewehrungsstäbe wurden in der Vergangenheit verstärkt Untersuchungen angestellt, um für bestimmte Anwendungsfälle eine Alternative neben den herkömmlichen aus Betonstahl oder Edelstahl bestehenden Metallstäben zu schaffen. Ein wesentlicher Anreiz für Versuche mit Kunststoffbewehrungsstäben liegt in der geringeren Wärmeleitfähigkeit bestimmter Kunststoffe (etwa Polyester, Vinylester etc.); auch lassen sich durch verschiedene Fasertypen wie etwa Glas-, Aramid- und andere Fasern die Zugfestigkeit und somit die Stabilität des Bewehrungsstabs sehr genau dem jeweiligen Anwendungsfall anpassen.Regarding such plastic reinforcement bars, reinforcements have been made in the past Investigations carried out to find an alternative for certain applications in addition to the conventional metal bars made of reinforcing steel or stainless steel to accomplish. A major incentive for tests with plastic reinforcement bars lies in the lower thermal conductivity of certain plastics (e.g. polyester, Vinyl esters etc.); different types of fibers such as glass, Aramid and other fibers the tensile strength and thus the stability of the reinforcing bar adapt very precisely to the respective application.
Ein wesentliches Problem der bekannten Kunststoffstäbe liegt jedoch darin, daß diese zwar im Fugenbereich zwischen zwei Betonbauteilen entsprechend den üblicherweise dort eingebauten Edelstahlstäben korrosionsbeständig sind, allerdings werden die verwendeten Fasern in den vom Beton beaufschlagten Bereichen durch das dort vorherrschende alkalische Milieu angegriffen, so daß sie hierdurch ihre kraftübertragende Funktion nicht mehr vollständig ausführen können. Verursacht wird dies dadurch, daß die als Hartmatrix der Zugstäbe verwendeten Kunststoffe in der Regel ein gewisses Potential an Mikrorissen aufweist, welche sich bei zusätzlicher Zugbeanspruchung zu Makrorissen entwickeln. Durch diese Makrorisse verliert die Hartmatrix gegenüber den Verstärkungsfasern ihre Schutzfunktion, so daß beispielsweise im Beton vorhandene alkalische Wässer Zugang zur Faseroberfläche haben und dort zerstörend bzw. korrodierend wirken können. Dies ist der wesentliche Grund dafür, daß Bewehrungsstäbe mit Verstärkungsfasern aus E-Glas und Aramid bis jetzt im Bauwesen noch keine nennenswerte Anwendung gefunden haben.A major problem of the known plastic rods, however, is that they are in the joint area between two concrete components according to the usual stainless steel rods installed there are corrosion-resistant, however the fibers used in the areas impacted by the concrete through there prevailing alkaline milieu attacked, so that it thereby their power-transmitting Can no longer perform the function completely. This is caused by that the plastics used as the hard matrix of the tension rods are usually a has a certain potential for microcracks, which can occur with additional tensile stress develop into macro cracks. The hard matrix loses due to these macro cracks against the reinforcing fibers their protective function, so that, for example, in Alkaline water present in concrete has access to the fiber surface and there can have a destructive or corrosive effect. This is the main reason that reinforcement bars with reinforcing fibers made of E-glass and aramid are still in use Construction have not yet found any significant application.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Bewehrungsstab aus Kunststoffmaterial zur Verfügung zu stellen, der sich durch verstärkte Resistenz gegenüber in Beton und Mörtel vorherrschende alkalischen Medien auszeichnet.Proceeding from this, the present invention is based on the object To provide reinforcement bar made of plastic material, which is reinforced by Resistance to alkaline media found in concrete and mortar distinguished.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Bewehrungsstab auf seiner Außenseite eine metallische Umhüllung aufweist, die geschlossen über die Außenseite umläuft und den faserverstärkten Kunststoff gegenüber der Umgebung diffusionsdicht abschirmt. Somit fungiert die metallische Umhüllung als Schutzschicht, so daß der faserverstärkte Kunststoff hinsichtlich seiner statischen und Wärmedämmeigenschaften ausgewählt werden kann, ohne hierbei die chemische Widerstandsfähigkeit in den Vordergrund zu stellen.This object is achieved in that the reinforcement bar has a metallic sheathing on the outside, which is closed over the Outside and the fiber-reinforced plastic compared to the environment shields against diffusion. So the metallic covering acts as a protective layer, so that the fiber-reinforced plastic in terms of its static and Thermal insulation properties can be selected without changing the chemical To put resilience in the foreground.
Diese metallische Umhüllung kann beispielsweise aus einer Metallfolie und insbesondere aus einer Edelstahlfolie bestehen, wobei schon geringste Foliendicken ausreichen können, um das Eindringen alkalischer Medien zu verhindern, wodurch gleichzeitig auch aufgrund der geringen Folienstärke die Wärmeleitfähigkeit nicht wesentlich ins Gewicht fällt bzw. bei einer Edelstahlfolie ohnehin recht gute Werte aufweist.This metallic envelope can for example consist of a metal foil and in particular consist of a stainless steel foil, whereby even the smallest foil thicknesses are sufficient can to prevent the penetration of alkaline media, which at the same time, due to the low film thickness, the thermal conductivity is not essential is significant or already has very good values for a stainless steel foil.
Der wesentliche Vorteil einer metallischen Umhüllung kommt dann zum Tragen, wenn
die metallische Umhüllung eine verlorene Form bildet, die bei der Herstellung des
Bewehrungsstabes verwendet wird, die also beispielsweise vor dem Gießen des Bewehrungsstabes
in die Form gegeben, anschließend mit dem faserverstärkten Kunststoffmaterial
gefüllt und hierbei gleich durchgängig mit diesem verbunden wird. Die
metallische Umhüllung kann auch während eines Pultrusionsprozesses als formgebende
Umhüllung bzw. Form oder Schalung dienen. Der Vorteil solcher Verfahren
liegt darin, daß quasi 
Um die insbesondere aus einem streifenförmigen Platten- oder Folienmaterial hergestellte metallische Umhüllung in die geforderte dem Stabquerschnitt angepaßte Rohr- bzw. Schlauchform zu bringen, kann das Platten- bzw. Folienmaterial an seinen Längsrändern miteinander verbunden sein, insbesondere durch Umfalzen, Prägen, Kleben, Schweißen und ähnliche Verbindungsarten.To those made in particular from a strip-like plate or film material metallic sheathing in the required pipe or pipe cross-section Bringing the shape of a tube can be the plate or film material on his Longitudinal edges must be connected to one another, in particular by folding, embossing, Gluing, welding and similar types of connections.
Darüber hinaus ist es natürlich auch möglich, daß die metallische Umhüllung aus einer Beschichtung besteht, die entweder die Gießform für den faserverstärkten Kunststoff beaufschlagt und nach dem Vergießen an der Außenseite des Bewehrungsstabes festgelegt wird, oder die den Kunststoffbewehrungsstab nach dessen Herstellung beaufschlagt.In addition, it is of course also possible that the metallic casing from a Coating exists which is either the mold for the fiber reinforced plastic acted upon and after grouting on the outside of the reinforcing bar is set, or the plastic reinforcement bar after its manufacture acted upon.
Unabhängig von der Art der Aufbringung der Umhüllung ist es aber wesentlich, daß die Umhüllung aus einem metallischen Material mit geringer Wärmeleitfähigkeit, insbesondere aus Edelstahl hergestellt ist. Hierdurch ist sichergestellt, daß der in der geringen Wärmeleitfähigkeit liegende Vorteil der Kunststoffbewehrungsstäbe nicht wesentlich beeinträchtigt wird, da man ansonsten gleich auch vollständig aus Metall hergestellte Stäbe verwenden könnte. Außerdem sollte die Umhüllung aus einem korrosionsbeständigen Material bestehen, um den Kunststoffbewehrungsstab dauerhaft gegenüber dem alkalischen Milieu des Betons schützen zu können.Regardless of the type of application of the covering, it is essential that the covering made of a metallic material with low thermal conductivity, in particular is made of stainless steel. This ensures that the Low thermal conductivity is not an advantage of the plastic reinforcement bars is significantly impaired, since otherwise it is also made entirely of metal could use manufactured rods. The wrapper should also be made of a corrosion resistant Material are made to make the plastic rebar permanent to protect against the alkaline environment of the concrete.
Was die Form der Umhüllung betrifft, so empfiehlt es sich, dieser eine strukturierte Außen- und/oder Innenfläche zu geben, welche beispielsweise durch Prägen oder ähnliche Verfahren hergestellt wird, um hierdurch den Formschluß mit dem Beton einerseits und mit dem Kunststoffmaterial andererseits zu verbessern, was gleichzeitig auch die Verbundeigenschaften des Bewehrungsstabes im Beton oder Mörtel verbessert. Insgesamt empfiehlt es sich entsprechend der Ausführungsform bei gerippten Metallstäben, daß auch der erfindungsgemäße Kunststoffbewehrungsstab auf seiner Außenseite gerippt ausgeführt ist, wobei zweckmäßigerweise auch Fasern oder andere geeignete Füllstoffe mit in die Rippen verlagert sind, um die dort auftretenden Scherbeanspruchungen sicher und dauerhaft abfangen zu können. Was die Form der Rippen betrifft, so läßt sich diese bei erfindungsgemäß hergestellten Stäben problemlos optimieren und den jeweiligen Einsatz-Gegebenheiten anpassen. As far as the shape of the wrapping is concerned, it is advisable to use a structured one To give outer and / or inner surface, for example by embossing or Similar process is made to thereby form fit with the concrete on the one hand and with the plastic material on the other hand to improve what at the same time also improved the composite properties of the reinforcing bar in concrete or mortar. Overall, it is recommended according to the embodiment with ribbed Metal bars that the plastic reinforcement bar according to the invention is ribbed on the outside, expediently also fibers or other suitable fillers are also shifted into the ribs in order to avoid those that occur there To be able to safely and permanently absorb shear stresses. What the Concerning the shape of the ribs, this can be the case with rods produced according to the invention optimize easily and adapt to the respective application conditions.
Bei Verwendung von Edelstahlfolie als metallisches Umhüllungsmaterial läßt sich sowohl eine Diffusionsdichtigkeit gegenüber alkalischen Medien als auch eine Korrosionsbeständigkeit für nicht vom Beton umgebene Stabbereiche erzielen. Werden jedoch anstelle von Edelstahl andere Metalle eingesetzt, wozu sich aufgrund der sehr geringen Kosten beispielsweise herkömmliches Dosenblech empfiehlt, so besitzen diese Metalle zwar die erforderliche Difussionsdichtigkeit, jedoch fehlt Ihnen in der Regel die gewünschte Korrosionsbeständigkeit. Eine solche Korrosionsbeständigkeit läßt sich jedoch ohne großen Aufwand dadurch erreichen, daß man den Bewehrungsstab mit metallischer Umhüllung beschichtet, wozu sich beispielsweise Epoxidharze anbieten.When using stainless steel foil as a metallic wrapping material, both diffusion tightness against alkaline media as well as corrosion resistance for rod areas not surrounded by concrete. However other metals are used instead of stainless steel low cost, for example, recommends conventional canned sheet, so own it these metals have the required diffusion tightness, but they are missing in the Usually the desired corrosion resistance. Such corrosion resistance can be achieved without great effort, however, by using the reinforcement bar coated with a metallic coating, for example epoxy resins to offer.
Ein vorteilhaftes Beschichtungsverfahren besteht darin, den Bewehrungsstab elektrostatisch aufzuladen und durch eine Pulververwirbelungskammer zu führen, wobei sich durch die elektrostatische Aufladung die Epoxidharzpulverpartikel an der Staboberfläche ablagern können. Anschließend werden die so aufgeladenen Stäbe durch eine Ofenstrecke geführt, und die Epoxidharzpartikel werden durch Wärmezufuhr von außen nach innen aufgeschmolzen. Besonders vorteilhaft ist in diesem Zusammenhang, daß erst die metallische Umhüllung die elektrostatische Aufladung ermöglicht, wohingegen der Faserkunststoff nicht leitend ist und demnach auch nicht direkt elektrostatisch aufgeladen werden kann.An advantageous coating method is to make the reinforcement bar electrostatic charge and pass through a powder swirl chamber, taking due to the electrostatic charge, the epoxy resin powder particles on the rod surface can deposit. Then the bars are charged by a Oven section, and the epoxy resin particles are caused by heat from the outside melted inside. In this context, it is particularly advantageous that only the metallic coating enables electrostatic charging, whereas the fiber plastic is not conductive and therefore not directly electrostatic can be charged.

Es sei noch angemerkt, daß anstelle einer längsnahtfreien rohr- bzw. schlauchförmigen Umhüllung und anstelle einer Umfalzung zweier aus Folienmaterial hergestellter Umhüllungshälften natürlich auch andere Herstellungsarten möglich sind, um eine geschlossene Umhüllung zu erzielen, beispielsweise eine Längsnahtschweißung, aber auch ein schraubengangförmiges Wickeln eines Folienmaterials unter Verfalzung bzw. Verschweißung benachbarter Wicklungsränder.It should also be noted that instead of a longitudinally tubular or tubular Wrapping and instead of crimping two made of foil material Wrapping halves of course other types of manufacture are possible to make a to achieve closed cladding, for example a longitudinal seam weld, but also a helical winding of a film material with interlocking or welding of adjacent winding edges.
Zusammenfassend bietet die vorliegende Erfindung den Vorteil, daß bei gleichbleibenden mechanischen Eigenschaften bekannter Kunststoffbewehrungsstäbe eine sichere Dichtigkeit gegenüber alkalischen Medien hergestellt werden kann, wodurch die demgemäß umhüllten Bewehrungsstäbe auch dauerhaft in Betonbauteile eingebaut werden können.In summary, the present invention offers the advantage that with the same mechanical properties of known plastic reinforcement bars a safe Tightness against alkaline media can be created, which the accordingly covered reinforcing bars are also permanently installed in concrete components can be.
