Abstract

Zum Entfernen eines im Innenraum einer Ankerschiene befindlichen Füllkörpers nach dem Abbinden des Betons ist in die Ankerschiene ebenfalls eine reißfeste Einlage eingelegt. Nach dem Abbinden des Betons kann durch Herausreißen dieser Einlage der Füllkörper zerstört werden und dessen Bruchteile aus dem Innenraum der Ankerschiene entfernt werden. In Anpassung an den individuellen Querschnitt der Ankerschiene und das Materiel des Füllkörpers sind verschiedene konstruktive Realisierungen der Einlage und des Füllkörpers denkbar, die im Endergebnis zu einer vollständigen Entfernung des Füllkörpers durch das Herausreißen der Einlage führen.To remove a filler located in the interior of an anchor channel after the concrete has set, a tear-resistant insert is also inserted into the anchor channel. After the concrete has set, the packing can be destroyed by tearing out this insert and its fragments removed from the interior of the anchor channel. In adaptation to the individual cross-section of the anchor channel and the material of the filler, various constructive realizations of the insert and the filler are conceivable, which in the end result in a complete removal of the filler by tearing out the insert.

Description

Die Erfindung betrifft eine Ankerschiene für die Bautechnik, die in einem Betonteil eingelassen wird und deren Innenraum von einem Füllkörper ausgefüllt ist, der nach dem Abbinden des umgebenden Betons entfernt wird.The invention relates to an anchor rail for construction technology, which is embedded in a concrete part and the interior of which is filled with a filler which is removed after the surrounding concrete has set.

Derartige Ankerschienen sind in verbreitetem Einsatz, sie dienen beispielsweise zur Aufnahme von Tragelementen, die die Ankerschiene hintergreifen. Oft sollen diese Tragelemente in der Ankerschiene verschiebbar sein, was voraussetzt, daß das Innere der Ankerschiene beim Einbringen des umgebenden Betons von Verschmutzungen frei bleibt. Aus diesem Grunde ist die Ankerschiene beim Einbetonieren mit einem Füllkörper versehen, der den Innenraum der Ankerschiene vor Verschmutzungen schützt. Dieser Füllkörper wird dann nach dem Abbinden des Betons entfernt, wozu man in der Regel mit irgendeinem Werkzeug diesen zerstört, so daß dessen Bruchteile aus der Ankerschiene entfernbar sind. Dieses Verfahren ist relativ zeitaufwendig und man benötigt ein geeignetes Werkzeug dazu.Such anchor channels are in widespread use, they are used, for example, to accommodate support elements which engage behind the anchor channel. Often, these support elements should be displaceable in the anchor rail, which presupposes that the inside of the anchor rail remains free of dirt when the surrounding concrete is introduced. For this reason, the anchor rail is provided with a filler during concreting, which protects the interior of the anchor rail from dirt. This filler is then removed after the concrete has set, for which purpose it is usually destroyed with some tool, so that its fragments can be removed from the anchor channel. This process is relatively time-consuming and a suitable tool is required.

Aufgabe der Erfindung ist es, eine Ankerschiene mit einem Füllkörper derart weiterzubilden, daß das Entfernen des Füllkörpers schneller und ohn Werkzeug erfolgen kann.The object of the invention is to develop an anchor rail with a filler body in such a way that the filler body can be removed more quickly and without tools.

Dies wird erfindungsgemäß dadurch gelöst, daß zum Entfernen des Füllkörpers eine reißfeste Einlage in den Innenraum der Ankerschiene eingebracht ist, die zumindest auf einer Seite die Ankerschiene überragt.This is achieved according to the invention in that a tear-resistant insert is inserted into the interior of the anchor rail to remove the filler body, which protrudes beyond the anchor rail at least on one side.

Das überragende Ende steht nach dem Einbetonieren auch aus der Betonoberfläche hervor, so daß durch das Herausreißen der Einlage auch der Füllkörper aus dem Inneren der Ankerschiene entfernt wird.The protruding end also protrudes from the concrete surface after concreting, so that the filler is also removed from the interior of the anchor channel by tearing out the insert.

Für die konstruktive Ausgestaltung des Zusammenwirkens zwischen Füllkörper einerseits und Einlage andererseits gibt es verschiene Möglichkeiten, so kann beispielsweise die Einlage als Klebeband ausgestaltet sein, das an der inneren Unterseite der Ankerschiene befestigt ist und den Füllkörper untergreift. Entscheidend ist, daß Einlage und Füllkörper so auf den Querschnitt der jeweiligen Ankerschiene angepaßt sind, daß beim Herausreißen der Einlage der Füllkörper möglichst in einer Form zerstört wird, daß die Bruchteile ohne zusätzliche Anstrengungen aus dem Innenraum der Ankerschiene herausfallen.There are various possibilities for the constructive design of the interaction between the filler body on the one hand and the insert on the other hand, for example the insert can be designed as an adhesive tape which is fastened to the inner underside of the anchor rail and engages under the filler body. It is crucial that the insert and filler are adapted to the cross-section of the respective anchor rail in such a way that when the insert is torn out, the filler is destroyed in such a way that the fractions fall out of the interior of the anchor rail without additional effort.

Vorteilhafterweise ist die Einlage parallel zur Ankerschiene eingebracht.The insert is advantageously introduced parallel to the anchor rail.

Ein Ausführungsbeispiel wird anhand der Zeichnung noch kurz erläutert:An exemplary embodiment is explained briefly using the drawing:

In ein Betonteil 30 ist eine Ankerschiene 10 mit einem Füllkörper 11 in ihrem Innenraum eingebettet. Zwischen dem Füllkörper 11 und der inneren Unterseite der Ankerschiene 10 liegt eine Einlage 12, die im dargestellten Ausführungsbeispiel aus einem mit Reißfäden verstärkten bandförmigen Gewebe besteht. An beiden Enden steht die Einlage 12 so weit über das Ende der Ankerschiene 10 über, daß nach dem Umgießen der Ankerschiene mit Beton ein ausreichendes Stück aus der Betonebene herausragt. Durch Ziehen in Pfeilrichtung an dem herausstehenden Ende der Einlage 12 wird der Füllkörper 11 zerstört, beispielsweise in Längsrichtung geteilt, so daß die beiden Hälften dann ohne zusätzliche Kraftanstrengung oder Werkzeug aus dem Innenraum der Ankerschiene 10 entfernt werden können.An anchor rail 10 with a filler 11 is embedded in its interior in a concrete part 30. Between the filler 11 and the inner underside of the anchor rail 10 there is an insert 12 which, in the exemplary embodiment shown, consists of a band-shaped fabric reinforced with tear threads. At both ends, the insert 12 projects so far beyond the end of the anchor rail 10 that a sufficient piece protrudes from the concrete level after the concrete has been cast around the anchor rail. By pulling in the direction of the arrow at the protruding end of the insert 12, the filler 11 is destroyed, for example divided in the longitudinal direction, so that the two halves can then be removed from the interior of the anchor rail 10 without additional effort or tools.

Die Ausgestaltung von Füllkörper 11 und Einlage 12 hängt vom konkreten Querschnitt der Ankerschiene einerseits und einer möglichst einfachen Fertigung dieser Einheit beim Ankerschienen-Hersteller ab. Hierbei ist es auch möglich, beispielsweise eine faden- oder schnurförmige Einlage 12 in das Innere eines Füllkörpers 11 bereits einzubetten, gegebenenfalls den Füllkörper auch noch mit Profilierungen in Form von Nuten oder Rillen zu versehen, so daß beim Herausreißen der Einlage 12 eine möglichst vollständige Zerstörung des Füllkörpers 11 erfolgt, wobei im optimalen Falle die Bruchteile derart geformt sind, daß sie ohne zusätzliche Werkzeuge aus der Ankerschiene 10 entnehmbar sind. Der Füllkörper kann beispielsweise aus vorgefertigten Hartschaumteilen bestehen, kann aber auch durch Anschäumen z.B. mit PU-Schaum, erzeugt werden. Die konkrete Realisierung bzw. Abstimmung der Eigenschaften des Füllkörpers und der Einlage sind durch Versuche anhand konkreter Ausführungsformen von Ankerschienen vom Fachmann ermittelbar und brauchen somit nicht näher erläutert zu werden.The design of filler 11 and insert 12 depends on the specific cross section of the anchor rail on the one hand and the simplest possible manufacture of this unit at the anchor rail manufacturer. Here, it is also possible, for example, to already embed a filament-shaped or cord-shaped insert 12 into the interior of a filler 11, optionally also to provide the filler with profiles in the form of grooves or grooves, so that when insert 12 is torn out, it is destroyed as completely as possible of the filler 11 takes place, the fractions being shaped in the optimal case such that they can be removed from the anchor rail 10 without additional tools. The packing can consist of prefabricated rigid foam parts, for example, but can also be made by foaming e.g. with PU foam. The concrete realization or coordination of the properties of the packing and the insert can be determined by a person skilled in the art by tests using concrete embodiments of anchor channels and therefore do not need to be explained in more detail.
