Description

Bisher bekannten einschlagbaren Wanddübelhülsen haftet der Nachteil an, daß 'eine Spreizung der kurzen Spitzen am inneren Ende der Hülse nicht möglich ist, so daß das gezackte Ende lediglich eine Sicherung gegen Verdrehung bietet. Bei anderen bekannten massiven Einschlagdübeln wird eine Spreizung des geschlitzten Endes durch eine unter der weichen Putzschicht liegende Hartsteinschicht bewirkt. Diese Dübelarten sind daher für ausgesprochen weiche Wände aus Lehm, weichem Gips, Kalkmörtel o. dgl. wenig geeignet. Previously known knock-in wall dowel sleeves have the disadvantage that 'a Spreading of the short tips at the inner end of the sleeve is not possible, so that the serrated end merely provides a safeguard against twisting. With other well-known massive drive-in dowels will spread the slotted end through an under the hard stone layer lying on the soft plaster layer. These types of dowels are therefore Not very suitable for extremely soft walls made of clay, soft plaster, lime mortar or the like.

Die Erfindung besteht darin, daß das innere Ende der rohrförmigen Dübelhülse aus spitzen, schlanken, dünnwandigen Zacken besteht, die sich beim Einschlagen der Hülse in weichen Wandbaustoff, wie Kalkputz, weichen Gips, Lehm o. dgl., in Richtung der Hülsenhalbmesser krallenförmig umbiegen. Die spitzen, schlanken Zacken der Hülse sind zweckmäßig schwach kegelförmig gespreizt. Auf der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt, und zwar zeigen dieThe invention consists in that the inner end of the tubular dowel sleeve consists of pointed, slender, thin-walled spikes that appear when the sleeve is hammered in in soft wall building material, such as lime plaster, soft plaster, clay o. The like., In the direction of Bend the sleeve radius like a claw. The pointed, slender prongs of the sleeve are expediently slightly conically spread. An exemplary embodiment is shown in the drawing of the subject matter of the invention, namely show the

Abb. 3 die in die Wand eingeschlagene Dübelhülse im Längsschnitt. Die rohrförmige metallene Dübelhülse e (Abb. 1) ist am inneren Ende mit spitzen, dünnwandigen, schlanken Zacken α versehen, die schwach kegelförmig gespreizt sind. Wird diese Hülse in einen weichen Wandputz aus Gips, Kalkmörtel, Lehm o. dgl. eingeschlagen, so spreizen sich die Spitzen α innerhalb des Wandbaustoffes d stark auseinander und biegen sich in Richtung des Hülsenhalbmessers krallenförmig um (Abb. 3), wobei der zwischen den spitzen Zacken zusammengedrängte Teil δ des Wandbaustoffes nicht nur fördernd auf das Umbiegen der Zacken 'einwirkt, sondern außerdem noch einen äußerst festen Sitz der spitzen Zacken« sichert. Die Dübelhülse ist damit nicht nur gegen Verdrehung, sondern auch zugleich gegen Herausziehen gesichert. Die Innenwandung der Dübelhülse <e kann in bekannter Weise mit Befestigungsmitteln für Schrauben, Haken, Ösen o. dgl., z. B. mit Gewinde, versehen sein. Die nach dem Einsqhlagen der Hülse vorhandene, starke Spreizung der Zackenspitzen hat zur Folge, daß dem Eindrehen der Schrauben ein erheblicher Widerstand entgegengesetzt wird, wodurch die Schrauben fest angezogen werden können.Fig. 3 the dowel sleeve driven into the wall in a longitudinal section. The tubular metal dowel sleeve e (Fig. 1) is provided at the inner end with pointed, thin-walled, slender prongs α , which are spread slightly cone-shaped. If this sleeve is hammered into a soft wall plaster made of gypsum, lime mortar, clay or the like, the tips α spread apart greatly within the wall building material d and bend claw-shaped in the direction of the sleeve radius (Fig. 3), with the between the pointed prongs pressed together part δ of the wall building material not only has a promoting effect on the bending of the prongs, but also ensures an extremely tight fit of the pointed prongs. The dowel sleeve is thus not only secured against rotation, but also at the same time against being pulled out. The inner wall of the dowel sleeve <e may in a known manner with attachment means for screws, hooks, eyelets o. The like., For example. B. threaded. The strong spreading of the prong tips that occurs after the sleeve has been inserted has the consequence that the screwing in of the screws is opposed to a considerable resistance, whereby the screws can be tightened firmly.
