Abstract

In the case of a ceiling dowel, in which an expansion element can pass through the head of the dowel body, the expansion element encloses the shaft of the dowel body by more than 180@ or in such a manner that an undercut and an expansion can take place in two lines running in opposite directions.

Description

Die Erfindung betrifft einen Dübel, der vorzugsweise in Decken montiert werden kann. Er unterscheidet sich von üblichen Spreizdübeln insofern, als er am Bohrlochende beim Setzen automatisch einen Hinterschnitt schafft.The invention relates to a dowel, which is preferably in Ceilings can be mounted. It differs from usual expansion dowels insofar as it is at the end of the borehole automatically creates an undercut when setting.

Bei der Erfindung dreht es sich um einen nagelförmigen Dübel, wie er an und für sich bekannt ist, und bei dem des Spreizelement durch einen Durchbruch des Kopfes vom Dübelkörper durchtreten kann.The invention is about a nail-shaped one Dowel as it is known in and of itself, and with the of the expansion element by a breakthrough of the head from Can penetrate dowel body.

Bei den derart bisher bekannten Dübeln erfolgt die Spreizung so, daß ein durch den Kopf des Dübelkörpers durchtretender Keil entlang des Dübelschaf­ tes geführt wird und schließlich aufgrund der Keilwirkung sich zwischen die Bohrlochwandung und den Dübelschaft klemmt, wodurch der Halt des Dübels erzielt wird. Dadurch treten aber unerwünschte Querkräfte auf. Nun sind Dübelkonstruktionen bekannt, bei denen auch eine Hinterschneidung erfolgt, wodurch die Querkräfte vermieden werden. Hierbei besteht aber der Dübel zwangsweise aus drei Teilen, nämlich einem Bolzen, einer Hülse und einer Scheibe.In those known so far Dowels are spread so that one through the head wedge passing through the dowel body along the dowel sheep tes and finally due to the wedge effect jams between the borehole wall and the dowel shaft, whereby the dowel is held in place. Step through it but undesirable lateral forces. Now there are dowel constructions known, where there is also an undercut, whereby the lateral forces are avoided. Here there is but the dowel is forcibly made of three parts, namely one Bolt, a sleeve and a washer.

Aufgabe der Erfindung war es aber auch, einen Dübel zu schaffen, der nur noch aus zwei Teilen besteht, wie es solche schon gibt, aber eben mit einer automatischen Hinterschneidung, die die Querkräfte ausschaltet.Object of the invention but it was also to create a dowel that only consists of two parts, as they already exist, but just with an automatic undercut that the Shut off lateral forces.

Der Dübelkörper 1 weist an seinem Kopf 2 einen ringförmigen Durchbruch 3 auf, in den die Hülse 4 gesteckt wird, bis zum Beginn des konischen Auslaufs 5 des Dübelkörpers 1.The dowel body 1 has at its head 2 an annular opening 3 into which the sleeve 4 is inserted until the conical outlet 5 of the dowel body 1 begins.

Beim weiteren Eintreiben der Hülse 4 aus dem Dübelkörper 1 bis zur Planfläche des Kopfes 2 läuft die Hülse wegen ihres Schlitzes 6 konisch auf, wodurch der Hinterschnitt und die spannungslose Spreizung erfolgen.When the sleeve 4 is driven in further from the dowel body 1 up to the flat surface of the head 2 , the sleeve tapered due to its slot 6 , as a result of which the undercut and the tension-free expansion take place.
