Abstract

The surface line of an expansion dowel exhibits pressed-in portions which are in the form of noses and occupy only a small part of the circumference of the expansion sleeve.

Description

Bei der Anmeldung dreht es sich um einen Spreizdübel, bei dem eine Hülse eingebogene Lappen aufweist, wie dies bereits bekannt ist. Bei der Er­ findung dreht es sich aber nicht um Lappen sondern Nasen, die ein gering­ fügiges Breitenmaß des Mantels am Durchmesser in Anspruch nehmen, wodurch die Hülse größtenteils an der Innenwandung des Bohrlochs in dem der Dübel sitzt, anliegt. Bei bisher bekannten Dübeln dieser Art gingen solche Lappen breitflächig von der Bohrlochwandung weg, wodurch beim Spreizvorgang nur ein Druck dort auf die Bohrlochwandung kam, wo der Knick in der Hülse angeordnet ist. Durch die Erfindung wird ein weit­ gehend ähnlicher Effekt erzielt, wie bei einem Dübel, dessen Spreizhülse aus vollem Material hergestellt ist, was aber einen unglaublichen Kosten­ unterschied zu einer Ausführung gemäß der Erfindung ausmacht.When registering, it is about an expansion dowel with a sleeve has bent lobes, as is already known. At the Er Invention is not about rags but noses that are a little Compliant width dimension of the jacket to take the diameter, whereby the sleeve mostly on the inner wall of the borehole in which the Dowel is seated. With previously known dowels of this type went such lobes over a wide area away from the borehole wall, whereby at Spreading only a pressure on the borehole wall came where the Kink is arranged in the sleeve. The invention is a far effect similar to that achieved with a dowel, the expansion sleeve is made of full material, which is an incredible cost differs from an embodiment according to the invention.

In der Hülse 1 sitzt der Treibbolzen 2, der mit seinem kegelförmigen Ende 3 an den Innenflächen 4 der Nasen 5 anliegt. Der Außendurchmesser der Nasen 5=D 1 entspricht dem Durchmesser D 2 der Hülse 1. Beim Ein­ treiben des Bolzens 2 in die Hülse 1 wird ein Druck über die Naseninnen­ seiten 4 auf die Nasenaußenseiten 6 übertragen, wodurch auf der ganzen Höhe der Nasen eine Kraftübertragung auf die Bohrungsinnenwand statt­ findet. Die Hülse 1 weist einen Längsschlitz 7 auf, der sich über die gesamte Hülsenlänge erstreckt, und einen solchen 8 auf, der sich über die Länge der Nasen erstreckt. Die Schlitze sind symmetrisch zu den Innen­ seiten 4 der Nasen 5 angeordnet.In the sleeve 1 , the driving pin 2 is seated, which rests with its conical end 3 on the inner surfaces 4 of the lugs 5 . The outside diameter of the lugs 5 = D 1 corresponds to the diameter D 2 of the sleeve 1 . When driving the bolt 2 in the sleeve 1 , a pressure on the inside of the nose 4 is transferred to the outside of the nose 6 , whereby a force transmission takes place on the inner wall of the bore on the entire height of the nose. The sleeve 1 has a longitudinal slot 7 , which extends over the entire length of the sleeve, and one 8 , which extends over the length of the lugs. The slots are arranged symmetrically to the inner sides 4 of the lugs 5 .
