Description

Zur Befestigung von Schrauben in Wänden aus Ziegelmauerwerk, Beton und ähnlichen Stoffen dienen sog. Dübel aus Holz oder Faserstoffen. Bekannt sind auch bereits-Dübel, die durch Anzug von Schrauben in dem vorgebohrten Wandloch gespreizt werden.For fastening screws in walls made of brickwork, concrete and similar materials, so-called dowels made of wood or fiber are used. Are known also already dowels, which are spread by tightening screws in the pre-drilled wall hole will.

Der Dübel gemäß der Erfindung ist jedoch einfacher. Er besteht aus einem Metallkonus, der eine gegebenenfalls mit Gewinde versehene zentrische Bohrung zur Aufnahme eines Befestigungsmittels besitzt, auf den sich ein Hohlzylinder aufsetzt, dessen Hohlraum an einem Ende derart konisch erweitert ist, daß sich der Hohlzylinder beim Eintreiben über den Metallkonus aufweitet und diesen gegen die Wand des Dübelloches verkeilt: In der Zeichnung ist ein Ausführungsbeispiel des neuen Dübels im Längsschnitt dargestellt, wobei der Hohlzylinder aus Weichmetall lose auf den in dem Loch zu befestigenden Metallkonus aufgesetzt gezeichnet ist.However, the dowel according to the invention is simpler. It consists of a metal cone that has a central bore, optionally provided with a thread has to accommodate a fastener on which a hollow cylinder is placed, the cavity of which is widened conically at one end in such a way that the hollow cylinder when driving in over the metal cone expands and this against the wall of the dowel hole Wedged: In the drawing, an embodiment of the new anchor is in longitudinal section shown, with the hollow cylinder made of soft metal loosely towards the in the hole attaching metal cone is drawn.

Der Dübelkörper besteht aus einem zylinderförmigen Schaft, der an dem Ende, das zuerst in das in der Wand vorgebohrte Loch eingeführt wird, sich konisch verbreitert und eine axiale Bohrung c zur Aufnahme eines beliebigen Befestigungsmittels, z. B. eines Nagels oder Hakens, besitzt. Die Bohrung c kann auch mit Gewinde versehen sein, so daß Schrauben darin befestigt werden können. In den ringförmigen Zwischenraum z-,vischen Schaft bz«-. Konus b und Mauer d wird ein Hohlzylinder a aus Weichmetall, z. B. Blei eingesetzt, dessen 1=lohlrauin an einem Ende ebenfalls entsprechend der Neigung des Metallkonus b sich konisch erweitert. Durch Hammerschläge wird der Hohlzylinder a über den Metallkonus b getrieben und ausgeweitet, so daß das Weichmetall des Hohlzylinders a in alle Unebenheiten der Wandung des yMauerloches eindringt und den Hohlraum zwischen Dübelkörper und Mauer satt ausfüllt. Durch Aufsetzen eines ringförmigen Werkzeuges, z. B. eines Stahlrohrs, kann das Weichmetall, auch wenn der Hohlzylinder a nicht mehr aus dem Loch herausragt, verstemmt werden, so daß der Dübelkörper sicher in dem Mauerloch festgehalten wird.The dowel body consists of a cylindrical shaft which, at the end that is first inserted into the hole pre-drilled in the wall, widens conically and has an axial bore c for receiving any fastening means, e.g. B. a nail or hook has. The bore c can also be threaded so that screws can be fastened therein. In the annular space z-, vischen shaft bz «-. Cone b and wall d becomes a hollow cylinder a made of soft metal, e.g. B. lead used, whose 1 = lohlrauin at one end also expands conically according to the inclination of the metal cone b. The hollow cylinder a is driven by hammer blows over the metal cone b and expanded so that the soft metal of the hollow cylinder a penetrates into all unevenness of the wall of the wall hole and fully fills the cavity between the dowel body and the wall. By placing an annular tool, e.g. B. a steel pipe, the soft metal, even if the hollow cylinder a no longer protrudes from the hole, caulked, so that the anchor body is securely held in the wall hole.
