Dübel
Die Erfindung betrifft einen Dübel aus Kunststoff, der durch Verkleben im Dübelloch fixiert ist, wobei der Dübel von der Dübelausnehmung mindestens eine radiale Ausnehmung, z. B. Schlitz, zum Dübelloch aufweist, durch den der Klebstoff durchtritt.
Bei den bisher bekannten Dübeln dieser Art tritt beim Einfüllen des Klebstoffes durch die Dübelausnehmung der Klebstoff hinter das innere Dübelende und schiebt zum Teil den Dübel aus dem Dübelloch heraus.
Um dies zu verhindern, sind gemäss der Erfindung an dem dem Dübelkopf abgewendeten Dübelende zum Verhindern des Austrittes an Klebstoff an dieser Stelle sich gegen die Dübellochwand abstützende, ein Zusammenpressen der geschlitzten Dübelenden bewirkende Sperrzungen angeordnet.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht, u. zw. ist im Mittelschnitt ein im Dübelloch des Mauerwerkes verklebter Dübel dargestellt.
Mit 3 ist der Dübel bezeichnet, der im Dübelloch 4a des Mauerwerkes 4 eingeschoben ist und einen Schlitz 5 aufweist, der vom inneren Dübelende 7 den Dübel zum Teil in bekannter Weise spaltet. Durch die Dübelausnehmung 3a wird mit einer Vorrichtung der Klebstoff 9 durch die Schlitze 5 in das Bohrloch 4a gedrückt. Damit der Dübel dabei nicht aus dem Bohrloch wandert, sind an dem dem Dübelkopf abgewendeten Ende 7 des Dübels 3 Sperrzungen 8 vorgesehen, die sich gegen die Dübellochwand 4a abstützen, so dass die Dübelenden 7 zusammengepresst werden, womit ein Austritt des Klebstoffes 9 an dieser Stelle verhindert wird.
Durch diese Sperrzungen 8 wird gleichzeitig eine zusätzliche Drehsicherung und eine Erhöhung des Anzugswertes erreicht, da die Zungen 8 in Verbindung mit dem verklebten Gesteinsmaterial auszughemmend wirken.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Dowels
The invention relates to a dowel made of plastic which is fixed by gluing in the dowel hole, the dowel from the dowel recess having at least one radial recess, e.g. B. slot, has to the dowel hole through which the adhesive passes.
In the previously known dowels of this type, when the adhesive is filled through the dowel recess, the adhesive occurs behind the inner dowel end and partially pushes the dowel out of the dowel hole.
In order to prevent this, according to the invention, locking tongues which are supported against the wall of the dowel hole and which compress the slotted dowel ends are arranged on the dowel end facing away from the dowel head to prevent the escape of adhesive.
In the drawing, an embodiment of the invention is illustrated, u. Between the middle section, a dowel glued in the dowel hole of the masonry is shown.
3 with the dowel is referred to, which is inserted in the dowel hole 4a of the masonry 4 and has a slot 5 which splits the dowel from the inner dowel end 7 in part in a known manner. Through the dowel recess 3a, the adhesive 9 is pressed through the slots 5 into the drill hole 4a with a device. So that the dowel does not migrate out of the drill hole, locking tongues 8 are provided on the end 7 of the dowel 3 facing away from the dowel head, which are supported against the dowel hole wall 4a, so that the dowel ends 7 are pressed together, whereby an escape of the adhesive 9 at this point is prevented.
By means of these locking tongues 8, an additional anti-rotation device and an increase in the tightening value are achieved at the same time, since the tongues 8 have a pull-out inhibiting effect in connection with the bonded rock material.
