Abstract

Dieser Dübel besitzt eine Anpassung für unterschiedliche Schraubengrößen und unterschiedliche Dübellochgrößen.This dowel has an adaptation for different screw sizes and different dowel hole sizes.

Description

Die Erfindung betrifft einen Spreizdübel nach dem Oberbegriff des einzigen Anspruchs.The invention relates to an expansion dowel according to the preamble of the single claim.

Ein derartiger Spreizdübel ist aus der DE-PS 28 10 503 bekanntSuch an expansion dowel is known from DE-PS 28 10 503

Der bei einem derartigen Spreizdübel nach Sprengen der Kapsel austretende Hartschaum neigt dazu, derart an der Schraube anzuhaften, daß ein wiederholtes Ein- und Ausschrauben der Schraube nicht möglich istThe rigid foam emerging from such an expansion dowel after the capsule has been exploded tends to do so to adhere to the screw so that repeated screwing in and screwing out of the screw is not possible

Der Erfindung liegt die Aufgabe zugrunde, einen Spreizdübel der eingangs genannten Art zu schaffen, der für ein wiederholtes Ein- und Ausschrauben der Schraube eine seit ■jtiätige Benetzung der Schraube mit Trennmittel ermöglicht.The invention is based on the object of creating an expansion dowel of the type mentioned above, that for repeated screwing in and screwing out of the screw a previous wetting of the screw with Release agent allows.

Die Erfindung wird in der folgenden Beschreibung anhand einer Zeichnung erläutert, i- der die einzige Figur einen Querschnitt durch einen derartigen Spreizdübel zei"t.The invention is explained in the following description with reference to a drawing, i- the only one Figure shows a cross section through such an expansion dowel.

Der Spreizdübel weist einen hülsenförmigen, durch eine Schraube aufspreizbaren Dübelkörper auf. In dem Dübelkörper ist eine mit einem Hartschaum ausbildenden Verschäumungsmaterial gefüllte Kapsel 42 angeordnet, die bei dem Einschrauben der Schraube durch diese gesprengt wird, wodurch das Verschäumungsmaterial aus der Kapsel 42 austritt und den Dübel in der Wand fest verankert.The expansion dowel has a sleeve-shaped dowel body which can be expanded by a screw. By doing A capsule 42 filled with a foaming material that forms rigid foam is arranged in the dowel body, which is burst when the screw is screwed in, causing the foaming material emerges from the capsule 42 and firmly anchors the dowel in the wall.

Um ein Verkleben der Schraube mit dem ausgetretenen Hartschaum zu vermeiden, ist ein — zeichnerisch nicht dargestellter — mit einem Trennöl getränkter Wattetupfer vorgesehen, durch den die Schraube beim Einschrauben dringt Diese Benetzung der Gewindegänge der Schraube mit dem Trennöl verhindert ein Anhaften des Schaumas an der Schraube und ermöglicht so ein wiederholtes Ein- und Ausschrauben dieser Schraube in den Dübelkörper.To prevent the screw from sticking to the hard foam that has leaked out, it is shown in the drawing not shown - soaked with a release oil provided cotton swab through which the screw when Screwing in penetrates This wetting of the threads of the screw with the release oil prevents penetration Adhesion of the foam to the screw and enables such a repeated screwing and unscrewing of this screw in the anchor body.
