Abstract
Description
Die Erfindung bezieht sich auf einen in Betonschalungen anzuordnenden und einzubetonierenden, aus Kunststoff bestehenden Einsatzkörper, wie namentlich Abstandhalter für Bewehrungen, Distanzelement, Spreize, Rohr, Abdeckleiste, Befestigungsteil u.dgl., der wenigstens auf einem Teil seiner Oberfläche mit einer die Verbindung zwischen ihm und dem ihn umgebenden Beton fördernden, Kunststoff enthaltenden Beschichtung versehen ist, die einen Anschluß für den Beton bildet.The invention relates to an insert body to be arranged in concrete formwork and to be concreted in, consisting of plastic, such as, in particular, spacers for reinforcements, spacer element, struts, pipe, cover strip, fastening part and the like, which connects the connection between it at least on part of its surface and the surrounding concrete-promoting, plastic-containing coating is provided, which forms a connection for the concrete.
Bei der Errichtung von Betonschalungen werden im Inneren der Schalung außer einer Bewehrung verschiedene andere Körper vorgesehen, die nach dem Gießen des Betons in diesem verbleiben. Dabei handelt es sich in erster Linie um Abstandhalter für Bewehrungen, sei es für vertikale Bewehrungen, Matten u.dgl. Die Abstandhalter können dabei unterschiedliche Formen aufweisen, die sich vielfach nach dem Ort der Anbringung bzw. dem jeweiligen Zweck richten. Von besonderem Vorteil sind längliche Abstandhalter, besonders in Form von leistenartigen, nach unten offenen Hohlprofilen, wie sie beispielsweise aus dem DE-U-77 30 442 und dem DE-U-82 24 733 hervorgehen.When erecting concrete formwork, various other bodies are provided inside the formwork in addition to reinforcement, which remain in the concrete after pouring. These are primarily spacers for reinforcements, be it for vertical reinforcements, mats and the like. The spacers can have different shapes, which often depend on the location of the attachment or the respective purpose. Elongated spacers are particularly advantageous, particularly in the form of strip-like hollow profiles which are open at the bottom, as can be seen, for example, from DE-U-77 30 442 and DE-U-82 24 733.
Außer Abstandhaltern gibt es noch zahlreiche andere Körper, die in einer Schalung vor dem Betonieren angebracht werden, z.B. Distanzleisten zum Ausrichten und Ansetzen von Schalungsteilen, Distanzspreizen für ähnliche Zwecke, rohrförmige Elemente, die in Verbindung mit Spannvorrichtungen für Betonschalungen verwendet werden und andere mit dem Aufbau und Zusammenhalt von Schalungsteilen benutzte Elemente.In addition to spacers, there are numerous other bodies that are installed in a formwork before concreting, for example spacer bars for aligning and attaching formwork parts, spacing brackets for similar Purposes, tubular elements used in connection with tensioning devices for concrete formwork and other elements used in the construction and cohesion of formwork parts.
In der überwiegenden Zahl aller Fälle bestehen solche Teile der verschiedensten Art, die hier allgemein unter dem Begriff der Einsatzkörper behandelt werden sollen, aus Kunststoff. Hier liegt ein Problem darin, daß eine möglichst gute Verbindung zwischen dem betreffenden Einsatzkörper und dem zu gießenden Beton zustande kommt. Schwierigkeiten können sich besonders bei glatten Kunststoffteilen ergeben.In the vast majority of all cases, such parts of the most varied types, which are to be dealt with generally here under the term insert bodies, are made of plastic. One problem here is that the best possible connection between the insert body in question and the concrete to be cast is achieved. Difficulties can arise especially with smooth plastic parts.
Aus der DE-A-1 646 509 ist eine sog. Kunststoffmauerstärke bekannt, deren Außenseite mit einer Mischung aus Zement, Kunststoffdispersion und evtl. Asbest bzw. andere Füller überzogen ist oder mit einer Mischung aus Epoxykleber und Zement und andere Füller überzogen ist. Es handelt sich also immer um eine Mischung, die Zement und Füllstoffe enthält. Die vorgeschlagenen Kunstoff-Dispersionen wirken als Klebstoffe, um den Überzug an der Mauerstärke anhaften zu lassen.A so-called plastic wall thickness is known from DE-A-1 646 509, the outside of which is coated with a mixture of cement, plastic dispersion and possibly asbestos or other fillers or is coated with a mixture of epoxy adhesive and cement and other fillers. So it is always a mixture that contains cement and fillers. The proposed plastic dispersions act as adhesives to adhere the coating to the wall thickness.
Aufgabe der Erfindung ist es, einen Einsatzkörper der genannten Gattung zu schaffen, bei dem die Haftungsverhältnisse zwischen ihm und dem Beton verbessert sind und der den Forderungen hinsichtlich einer guten Verbindung zwischen ihm und dem Beton in besonderem Maße gerecht wird. Es ist dabei auch an eine hohe Dichtheit gedacht. Die Erfindung richtet sich grundsätzlich auf alle Einsatzkörper, bei denen es auf eine derartige Verbindung ankommt. Solche Teile sind weiter oben in einer nicht vollständigen Aufzählung genannt. Mit alledem zusammenhängende weitere Probleme, mit denen sich die Erfindung befaßt, ergeben sich aus der jeweiligen Erläuterung der aufgezeigten Lösung.The object of the invention is to provide an insert body of the type mentioned, in which the liability conditions between it and the concrete are improved and which particularly meets the requirements for a good connection between it and the concrete. A high level of tightness is also considered. The invention is basically directed to all insert bodies in which such a connection is important. Such parts are mentioned above in an incomplete list. Related to all of these other problems that the Invention concerns arise from the respective explanation of the solution shown.
Gemäß der Erfindung ist für die Beschichtung des Einsatzkörpers ein Polyurethan-Kunststoff vorgesehen, der mit dem Material des Einsatzkörpers an dessen Oberfläche durch chemische Wirkung verbunden ist und gute Anbindungseigenschaften für den Beton hat.According to the invention, a polyurethane plastic is provided for the coating of the insert body, which is connected to the material of the insert body on its surface by chemical action and has good binding properties for the concrete.
Damit ist über bekannte Maßnahmen hinaus eine besonders intensive Verbindung zwischen dem Einsatzkörper und seiner Beschichtung erzielt. Durch den chemisch bewirkten Zusammenhalt erhält der Einsatzkörper, und zwar gerade auch ein ursprünglich glatter Einsatzkörper, praktisch eine neue Oberfläche, die sich von ihm nicht mehr trennen läßt und die ihrerseits die feste Verbindung mit dem Beton vermittelt.In addition to known measures, a particularly intensive connection is thus achieved between the insert body and its coating. Due to the chemically induced cohesion, the insert body, and in particular an originally smooth insert body, is given a practically new surface which can no longer be separated from it and which in turn provides the firm connection with the concrete.
Für die Beschichtung kommt auch ein Zweikomponenten-System in Betracht.A two-component system can also be used for the coating.
Die Beschichtung kann ein zusätzliches Material enthalten, das kein Kunststoff ist, aber seinerseits noch einen Beitrag für die intensive Verbindung mit dem Beton liefert. Dafür kommt insbesondere ein Material in Betracht, welches dem Beton oder seinen Bestandteilen verwandt ist.The coating can contain an additional material that is not plastic, but in turn also contributes to the intensive connection with the concrete. A material that is related to the concrete or its components is particularly suitable.
Das Aufbringen des Kunststoffes kann durch Aufstreichen, Aufsprühen oder durch einen Tauchvorgang erfolgen. Insbesondere wird zumindest ein Teil der Beschichtung kontinuierlich auf den bzw. die Einsatzkörper aufgebracht.The plastic can be applied by brushing, spraying or by dipping. In particular, at least part of the coating is applied continuously to the insert body (s).
