Description

Die bekannten im Gehrauch befindlichen, aus zwei Teilen bestehenden Stahldübel mit Gewindebohrung zum Befestigen der Isolatorenrollen für elektrische Leitungen, die sich durch Auftreiben einer gespaltenen Hülse auf einen konischen Teil am Ende des Bolzens selbst befestigen, müssen in entsprechende vorgetriebene Löcher eingedübelt bzw. eingegipst oder einzementiert werden, da die Bolzen verto möge ihrer Beschaffenheit und Gestaltung sich nicht zum direkten Einschlagen in die Wandungen eignen. Anderseits besitzen die beispielsweise bei der Reichspost gebräuchlichen einfachen prismatischen Einschlagdübel wiederum den Nachteil, daß sie nach dem Einschlagen meist nicht festsitzen, sondern sich lockern und herausfallen.The well-known in the ear smoke, consisting of two parts steel dowels with Threaded hole for attaching the insulating rollers for electrical cables that are located by driving a split sleeve onto a conical part at the end of the bolt fasten it yourself, must be dowelled or plastered into the corresponding pre-driven holes or cemented in, since the bolts may verto their nature and design are not suitable for direct hammering into the walls. On the other hand, they own For example, the simple prismatic drive-in dowels commonly used in the Reichspost again the disadvantage that after being hammered in, they are usually not stuck, but loosen up and fall out.

Diese Übelstände werden durch die vorliegende Erfindung vollständig beseitigt, indem durch Kombination der Eigenschaften vorgenannter Dübel ein einschlagbarer, sich selbst befestigender Stahldübel geschaffen wurde, bei welchem ein aus profiliertem, vorn zugespitztem Stahl mit hinten verengtem Schaft bestehender Dübel direkt in die Wandung eingetrieben und sodann eine vom gleichen Profil hergestellte, auf einer Seite mit Einschnitten versehene Überschubhülse aus weicherem Material nachgeschlagen wird, : wobei die aufgeschlitzten Seitenteile an den konischen Übergangsstellen der verdickten Spitze des Stahldübels seitlich auseinander- ! getrieben werden, wodurch Dübel· und Über- '. schubhülse sich von selbst befestigen. !These inconveniences are completely eliminated by the present invention in that a knock-in, self-fastening steel dowel was created by combining the properties of the aforementioned dowels, in which a dowel consisting of profiled, pointed steel with a shank narrowed at the back is driven directly into the wall and then a from the same profile and provided with incisions on one side of a sliding sleeve made of softer material is looked up, with the slit side parts at the conical transition points of the thickened tip of the steel dowel laterally apart! are driven, whereby dowels · and over- '. push sleeve attach by itself. !

Der durch diesen Dübel nicht zu verkennende technische Fortschritt besteht darin, daß das leichte Eintreiben des Dübels in die Wandung mit einer besonders sicheren Befestigung und Sicherung gegen Verdrehung vereinigt wird.The technical progress, which cannot be ignored by this dowel, consists in that the easy driving of the dowel into the wall with a particularly secure fastening and protection against rotation is combined.

Der aus profiliertem Stahl hergestellte Dübel α (Abb. 1) verläuft auf einer Seite konisch in eine verdickte Spitze b aus, auf der anderen Seite ist er in bekannter Weise mit Innengewinde c zur Aufnahme der Befestigungsschraube d versehen. Das Hohlraumprofil e der Überschubhülse f (Abb. 2) paßt genau über das Stahldübelprofil a, und das Außenprofil g dieser Hülse stimmt ebenso mit dem Außenprofil der verdickten Spitze b des Stahldübels überein, so daß, wenn der Stahldübel α in das Mauerwerk eingeschlagen ist, die Überschubhülse f den durch die verdickte Spitze b gebildeten Hohlraum zwischen dem Dübel α und dem umliegenden Mauerwerk gerade ausfüllt (Abb. 3). Da nun die Überschubhülse f auf jener der Dübelspitze b zugekehrten Seite mit Einschnitten h versehen ist, so werden, wenn die Überschubhülse vollends eingeschlagen wird, die eingeschlitzten Seitenteile i an den konisch verlaufenden Übergangsflächen k der Dübelspitze b seitlich auseinandergetrieben, wodurch Dübel und Überschubhülse sich selbst befestigen. The dowel α made of profiled steel (Fig. 1) runs conically on one side into a thickened tip b , on the other side it is provided in a known manner with internal thread c for receiving the fastening screw d. The cavity profile e of the sleeve f (Fig. 2) fits exactly over the steel dowel profile a, and the outer profile g of this sleeve also matches the outer profile of the thickened tip b of the steel dowel, so that when the steel dowel α is hammered into the masonry, the sleeve f just fills the cavity formed by the thickened tip b between the dowel α and the surrounding masonry (Fig. 3). Since the push-on sleeve f is now provided with incisions h on the side facing the dowel tip b , when the push-on sleeve is completely hammered in, the slotted side parts i on the conical transition surfaces k of the dowel tip b are driven apart laterally, causing the dowel and the push-on sleeve to become self-contained attach.
