Description

Die Erfindung betrifft eine Betonstruktur, die sich zum kathodischen Korrosionsschutz bei gleichzeitiger Verstärkung von Bauwerken eignet und insbesondere im Rahmen von Sanierungsverfahren verwendet werden kann.The invention relates to a concrete structure that is cathodic Corrosion protection with simultaneous reinforcement of buildings is suitable and can be used especially in the context of renovation processes.

Der kathodische Korrsionsschutz ist ein an sich bekanntes Verfahren zum Schutz von Eisen. Zur Verhinderung der Korrosion wird nach dem Stand der Technik häufig eine Opferanode eingesetzt, die aufgrund ihrer gegenüber dem zu schützenden Metall grösseren Elektropositivität allmählich oxidiert wird und in Lösung geht. Eine weitere Möglichkeit ist in der Literaturstelle "Betoninstandsetzung mit System", IP Bau 1993, ISBN 3-905234-71-8, Kapitel 3.2 beschrieben, wo ein Titannetz mit daran angelegtem, äusseren Potential für den kathodischen Korrosionsschutz vorgeschlagen wird. Allerdings weist Titan ein beträchtliches Gewicht auf und ist ausserdem sehr teuer und somit unwirtschaftlich. Zudem wird dadurch mit wirtschaftlich vertretbarem Aufwand keine substantielle Verstärkung der Betonstruktur in mechanischer Hinsicht erreicht.Cathodic protection against corrosion is a known method to protect iron. To prevent corrosion, according to the state technology often used a sacrificial anode, due to its opposite the metal to be protected with greater electropositivity is gradually oxidized and goes into solution. Another possibility is in the literature "Concrete repair with a system", IP Bau 1993, ISBN 3-905234-71-8, chapter 3.2 describes where a titanium mesh with external potential attached to it is proposed for cathodic corrosion protection. However, points Titanium has a considerable weight and is also very expensive and therefore uneconomical. It also makes it economically justifiable no substantial reinforcement of the concrete structure in mechanical terms reached.

Auch andere, bekannte Systeme zum Schutz, bzw. zur mechanischen Verstärkung von Betonstrukturen weisen jedoch verschiedene schwerwiegende Nachteile auf. In der Praxis ist es beispielsweise üblich, Betonstrukturen des Standes der Technik durch Einbettung von Stahlplatten zu verstärken. Auch diese weisen indes ein erhebliches Gewicht auf und sind daher schwierig zu handhaben und zu applizieren. Zudem lässt sich dadurch die Armierung in keiner Weise gegen Korrosion schützen. Other known systems for protection or mechanical Reinforcing concrete structures, however, have several serious disadvantages. In practice, for example, it is common Prior art concrete structures by embedding steel plates strengthen. However, these also have a considerable weight and are therefore difficult to handle and apply. In addition, do not protect the reinforcement against corrosion in any way.

Aufgabe und LösungTask and solution

Es ist daher Aufgabe der vorliegenden Erfindung, die Nachteile des bestehenden Standes der Technik zu überwinden und eine Betonstruktur zur Verfügung zu stellen, die sowohl die vorhandene Armierung wirksam gegen Korrosion schützt, als auch gleichzeitig eine Verstärkung des Betons bewirkt. Mit Hilfe einer erfindungsgemässen Betonstruktur wird insbesondere eine praktische und wirtschaftliche Möglichkeit zur Verfügung gestellt, um sowohl die Anforderungen eines präventiven Korrosionsschutzes, als auch die Möglichkeit zur nachträglichen Sanierung von bereits angegriffenen Bauwerken wirkungsvoll in einer einzigen Massnahme zu kombinieren. Zudem kann man auch mit Hilfe einer erfindungsgemässen Betonstruktur die Belastbarkeit eines bestehenden Bauwerks nachträglich den möglicherweise gestiegenen Anforderungen Rechnung tragen, ohne dass ein Abriss, bzw. eine völlige Neukonstruktion erforderlich wird.It is therefore an object of the present invention to overcome the disadvantages of to overcome existing state of the art and a concrete structure for To provide effective against both the existing reinforcement Corrosion protects and at the same time reinforces the concrete. With the help of a concrete structure according to the invention, a practical and economical way provided to both the requirements of preventive corrosion protection, as well as the Possibility to retrofit already attacked ones Combining buildings effectively in a single measure. In addition, the concrete structure according to the invention can also be used Resilience of an existing building may be retroactive take increased requirements into account, without a demolition or complete redesign is required.
