Description
Die Erfindung betrifft einschlagbare, an beiden Enden offene Dübelhülsen aus Stahlblech zur Befestigung von Schrauben und Stiften.The invention relates to knock-in dowel sleeves made of sheet steel, open at both ends for fastening screws and pins.
Es sind bereits einschlagbare, an beiden Enden offene Dübelhülsen aus Stahlblech mit und ohne Innengewinde wie auch mit inneren Längsrippen versehene Spreizdübel aus Weichmetall, in denen das Gewinde durch eine" ίο Schraube erzeugt wird, bekannt.There are already knock-in dowel sleeves made of sheet steel open at both ends and expansion dowels made of soft metal without internal thread as well as with internal longitudinal ribs, in which the thread is generated by a "ίο screw, known.
Die Erfindung besteht nun darin, daß die Stahlblechhülse innen mit Längsrippen aus weichem Metall versehen ist. Hierdurch wird erreicht, daß Befestigungsschrauben mit be-Bebigem Gewinde verwendet werden können und trotz der Verwendung von weichem Metall die Einschlagfähigkeit des Dübels nicht beeinträchtigt ist.The invention consists in that the sheet steel sleeve is made with longitudinal ribs on the inside soft metal is provided. This ensures that fastening screws with be-Bebigem Threads can be used and despite the use of soft metal the ability of the anchor to be hammered in is not impaired.
Der Dübel vereinigt mithin in sich die Vorzüge der Dübel aus nachgiebigem Stoff mit denjenigen der einschlagbaren, an beiden Enden offenen Dübelhülsen.The dowel therefore combines the advantages of the dowels made of flexible material those of the knock-in dowel sleeves open at both ends.
In der Zeichnung sind AusführungsbeispieleIn the drawing are exemplary embodiments
des Dübels dargestellt, und zwar zeigen die Abb. ι und 3 eine zylindrische und die Abb. 2 und 4 eine sechskantige Stahlblechhülse im Längs- und Querschnitt.of the dowel, namely Figs. ι and 3 show a cylindrical and Fig. 2 and 4 a hexagonal sheet steel sleeve in longitudinal and cross-section.
Die aus Stahlblech hergestellten Dübelhülsen b sind an ihren Innenflächen mit schmalen, gleichmäßig verteilten Längsrippen aus weichem Metall versehen. The dowel sleeves b made of sheet steel are provided on their inner surfaces with narrow, evenly distributed longitudinal ribs made of soft metal.
Die Längsrippen werden im Lötverfahren nach fertiger Bearbeitung und Härtung der Hülse unter Zuhilfenahme eines Doms mit Längsnuten, die dem Profil der Rippen entsprechen, befestigt.The longitudinal ribs are soldered after processing and hardening of the Sleeve with the aid of a dome with longitudinal grooves that correspond to the profile of the ribs, attached.
Die Längsrippen α haben dreieckigen Querschnitt und bestehen aus weichem MetaE oder einem anderen nachgiebigen Stoff. Der Rükken der Rippen« ist gegenüber ihrem breiteren Fuß schmal gehalten, und zwar einerseits, um dem beim Einschlagen durch die Hülse durchfließenden Steinmehl nicht hinderlich zu sein, und andererseits, um dem. Eindringen des Schraubengewindes einen möglichst geringen Widerstand zu bieten. Damit die Hülse leicht in das Mauerwerk eingeschlagen werden kann, ist sie am" inneren Ende angeschärft.The longitudinal ribs α have a triangular cross-section and are made of soft MetaE or another flexible material. The back of the ribs is kept narrow compared to its broader foot, on the one hand so as not to be a hindrance to the stone dust flowing through the sleeve when it is hammered in, and on the other hand to prevent it. Penetration of the screw thread to offer the lowest possible resistance. So that the sleeve can be easily knocked into the masonry, it is sharpened at the "inner end".
Die aus weichem Metall bestehenden Längsrippen ermöglichen die Verwendung von Schrauben mit beliebigem Gewinde und gewähren auch glatten Stiften einen sicheren, Halt.The longitudinal ribs made of soft metal allow the use of Screws with any thread and also guarantee smooth pins a safe, Stop.
