Abstract

The system is used for removing built-in components from concrete, together with the cast material, by turning them like a screw. It enables replacement of anchoring units. Cutout units (2), specially formed, are used for making cutouts in the concrete (3), with surface endowed with a thread shape. Cutout surfaces may be treated with a separating medium such as bitumen, grease, wax or graphite or a specially shaped thin-walled unit, with helical thread, may be screwed into the cutouts as separator. It is made much easier to remove damaged components from concrete.

Description

Verfahren für auswechselbare Verankerungen im Beton vonProcedure for replaceable anchorages in concrete from

Einbauteilen Die Erfindung betrifft auswechselbare Verankerungen von Einbauteilen im Betonkörper. Diese Einbauteile werden in Bauwerken wie Brücken, Stützmauern, Parkhäusern, Einzelfundamenten und Streifenfundamenten usw. eingesetzt in Form von Pfosten für Schutzplanken, Geländern, Lärmschutzwänden und dergleichen, die dem Straßenverkehr direkt ausgesetzt sind und deshalb bei Beschädigung ausgewechselt werden müssen.Built-in parts The invention relates to replaceable anchorages of Built-in parts in the concrete body. These built-in parts are used in structures such as bridges, Retaining walls, parking garages, individual foundations and strip foundations, etc. are used in the form of posts for crash barriers, railings, noise barriers and the like, which are directly exposed to road traffic and are therefore replaced if damaged Need to become.

Diese Einbauteile werden üblicherweise nachträglich versetzt und auf einbetonierte Ankerplatten geschweißt oder geschraubt oder mittels Ankerplatten aufgedübelt oder mittels einbetonierten Gewindestangen verschraubt oder in Betonaussparungen versetzt. Bei diesen vorhandenen Möglichkeiten gibt es Schwierigkeiten sowohl bei der Montage als auch bei der Auswechslung. Werden die Einbauteile mit einbetonierten Ankerplatten oder einbetonierten Gewindestangen verschraubt, so muß von der Baustelle eine hohe Paßgenauigkeit der Ankerplatten oder Gewindestabe verlangt werden, die nur sclllecht zu erreichen ist. Mittels Ankerplatten eingedübelte Einbauteile bringen Nachteile, da bei Anprall von Fahrzeugen die Dübel häufig aus dem Beton herausgerissen werden und Krater und Beschädigungen im Beton hinterlassen. Ansckiießend müssen erneut in den Beton Dübellöcher für die Verankerung gebohrt werden. Ebenso wird beim Arbeiten mit Dübeln und Gewindestanen das Gewinde so beschädigt, da es für die Verschraubung nicht mehr verwendbar ist. Beim Einbetonieren der Einbauteile ist eine Auswechslung nur dadurch möglich, daß sie aus dem Beton gestemmt werden0 Alle vorher genannten Systeme bringen einen großen Aufwand hinsichtlich Gerät und Arbeitsleistung mit sich, was zu Unwirtschaftlichkeit beim Auswechseln der Einbauteile führt Die Erfindung des Verfal rens für auswecllselbare Verankerungen von Einbauteilen in Betonkörpern ist dadurch gekennzeichnet, daß wiedergewinnbare runde Aussparungsschalungen mit Profil, deren Profilierung einer Sclirauhenlinie folgt, in den Beton eingebaut werden. Diese Aussparungsschlalungen mit Gewindeprofil werden nach dem Erhärten des Betons herausgedreht, sodaß auch die Oberflächen des Betons in diesen Aussparungen einer Schraiibenlinie folgen. Eventuell entstandene Felilstellen in den Aussparungen z.B. durch Lufteinschlüsse im Beton werden anschl ießend mit Mörtel, Schnellbinder, Kunststoff oder ähnlichem ausgebessert.These built-in parts are usually moved and on afterwards Concrete anchor plates welded or screwed or by means of anchor plates Doweled or screwed in using threaded rods embedded in concrete or in concrete recesses offset. With these existing options there are difficulties with both assembly as well as replacement. Are the built-in parts with concreted in Anchor plates or screwed-in threaded rods must be provided by the construction site a high accuracy of fit of the anchor plates or threaded rods are required can only be reached badly. Bring in doweled built-in parts using anchor plates Disadvantages, as the dowels are often torn out of the concrete when vehicles hit and leave craters and damage in the concrete. Ultimately, must dowel holes must be drilled into the concrete again for anchoring. Likewise will When working with dowels and threaded rods, the thread is so damaged that it is suitable for the screw connection can no longer be used. When concreting the built-in parts they can only be replaced by prying them out of the concrete0 All of the systems mentioned above involve a great deal of effort in terms of equipment and Labor output with it, resulting in inefficiency when replacing the built-in parts The invention of the procedural method for removable anchoring of built-in parts in concrete bodies is characterized in that recoverable round recess formwork with a profile, the profile of which follows a roughened line, built into the concrete will. These recess formations with a thread profile are after hardening of the concrete turned out so that the surfaces of the concrete in these recesses follow a screw line. Any patches that have arisen in the recesses e.g. due to air inclusions in the concrete, mortar, quick-release binders, Repaired plastic or the like.

Diese so geschaffene Aussparung wird vor dem Einbau mit einem Trennmittel z.B. Bitumen, Kunststofflack, Fett, Wachs, Graphit oder ähnlichem oder einer Kombination vorgenannter Mittel behandelt. Nach dieser Behandlung des Betons werden die Einbauteile in die Aussparungen versetzt und mit Aussparungsbeton, scllwindfreiem Mörtel oder Kunststoff vergossen.This recess created in this way is coated with a release agent before installation e.g. bitumen, plastic paint, grease, wax, graphite or the like or a combination the aforementioned means treated. After this treatment of the concrete, the built-in parts in the recesses offset and with recess concrete, wind-free mortar or plastic shed.

Durcli das Trennmittel wird sichergestellt, daß sich der Vergußbeton nicht mit dem anderen Beton verbindet, jedoch durch die Verzahnullg durch das Schraubengewinde in der Aussparung eine hervorragende Verankerung gegen llerausziellen erhält. Weiterhin kann in den Vergußbeton ein Röhrchen eingebaut werden, das bis zum Boden der Aussparung reicht.The release agent ensures that the grouting concrete does not connect to the other concrete, but through the toothing through the screw thread in the recess an excellent anchorage against extras is obtained. Farther a tube can be built into the grouting concrete that extends to the bottom of the recess enough.

Dieses Röhrchen wird nach dem Einbau der Einbauteile mit einem Deckel versc1ilossen, um ein Eindringen des Wassers zu verhindern.After the installation parts have been installed, this tube is covered with a lid closed to prevent water from entering.

Wenn das Einbauteil durch Gewalteinwirkung bescfiädigt oder zerstört ist, wird das Einbauteil zusammen mit dem abgebundenen Vergußbeton aus dem Beton wie eine Schraube herausgedreht. Das eventuell eingesetzte Röhrchen wird dabei geöffnet, um einen entstehenden Unterdruck am Boden der Aussparung zu verhindern.If the built-in part is damaged or destroyed by force is, the built-in part is removed from the concrete together with the hardened grouting concrete unscrewed like a screw. The inserted tube is opened, in order to prevent a negative pressure from occurring at the bottom of the recess.

Nach dem Ausbau der beschädigten oder zerstörten Einbauteile können nach einer erneuten Behandlung der Aussparung wiederum Einbauteile nach dem vorher beschriebenen Verfahren eingebaut werden0 Die Erfindung des Verfalirens für auswec}lselbare Verankerungen von Einbauteilen im Beton wird in der Zeichnung am Beispiel von Verankerungen von Schutzplankenpfosten in einer Kappe einer Brücke näher dargestellt.After removing the damaged or destroyed built-in parts after a renewed treatment of the recess again built-in parts after the previous one The invention of the procedure for selectable ones Anchoring of built-in parts in concrete is shown in the drawing using the example of anchoring of guard rail posts in a cap of a bridge shown in more detail.
