Description

Die Erfindung betrifft einen Dübel für eine Wand aus porösem Material wie z.B. Gasbeton, bestehend aus zwei U-förmigen Schalen, die mittels eines unter Gewindezugkraft in die beiden Schalen einziehbaren Spreizkörpers aufspreizbar sind, wobei die Schenkel der beiden U-förmigen Schalen vom vorderen Dübelende ausgehend nach dem hinteren, bis zu ihren parallel zur Dübelachse verlaufenden freien Längskanten mit einer Abschrägung versehen sind, auf der und gegegenenialls auf den Längskanten der an dem vorderen Dübelende unverlierbar angeordnete Spreizkörper beim Einziehen gleitet.The invention relates to a dowel for a wall made of porous material such as aerated concrete, consisting of two U-shaped shells that are held by means of a threaded pull in the two shells retractable expansion body are expandable, the legs of the two U-shaped shells, starting from the front end of the dowel towards the rear, up to their parallel to the dowel axis running free longitudinal edges are provided with a bevel, on the and Gegegenialls on the longitudinal edges of the expanding body, which is captively arranged at the front end of the dowel Pulling in slides.

Der Dübel für eine Wand aus porösem Material nach dem Hauptpatent erfährt durch Einziehen eines Spreizkörpers in die beiden Schalen eine über das bekannte Maß wesentlich hinausgehende Aufspreizung. Das Mindestmaß der Aufspreizung ergibt sich aus dem DurchmesserThe dowel for a wall made of porous material according to the main patent learns by pulling in an expansion body in the two shells a spread that goes far beyond the known extent. The minimum the spread results from the diameter

des Spreizkörpers und der doppelton Tiefe der U-förmigen Schalen. Da aber durch die U-Form der beiden Halbschalen ein Umbiegen hinter dem Spreizkörper nahezu ausgeschlossen ist, ist in Wirklichkeit die Auf spreizung v;eitaus größer. Beim Einziehen gleitet der Spreizkörper auf den beiden U-förmigen Schalen, die vom vorderen Dübelende ausgehend nach dem hinteren bis zu ihren parallel zur Dübelachse verlaufenden freien Längskanten mit einer Abschrägung versehen sind. Das im Anfangsstadium der Aufspreizung nahezu im rechten Winkel zur Längsache nach außen gerichtete Kraftmoment nähert sich mit zunehmender Aufspreizung immer mehr der Längsachse des Dübels. Dadurch verringert sich mit zunehmender Aufspreizung der Hebelarm und damit auch das die Aufspreizung bewirkende Kraftmoment. An dem Punkt, an dem die Kraftrichtung durch den Gelenkpunkt verläuft, wird der Wert des Kraftmomentes zu Null. Wird der Gelenkpunkt sogar unterschritten, kehrt sich die Drehrichtung des Kraftmomentes um und bewirkt eine Verringerung des bis dahin erreichten Aufspreizwinkels. Der Dübel nach dem Hauptpatent kann somit nicht vollständig aufgespreizt werden. Dennoch ist ein Aufspreizwinkel zwischen den beiden Halbschalen von etwa 90 möglich, der noch weit über dem liegt, was bisher mit den bekannten Dübeln erreicht werden konnte.of the expansion body and the double depth of the U-shaped shells. But because of the U-shape of the bending behind the expansion body is almost impossible for both half-shells, is in reality the spread much larger. When pulling in, the spreader slides on both of them U-shaped shells that run from the front end of the dowel towards the rear up to their parallel to the dowel axis running free longitudinal edges are provided with a bevel. That in the initial stage of the spreading almost at right angles The moment of force directed outwards towards the longitudinal axis approaches more and more with increasing spread the longitudinal axis of the anchor. As a result, the lever arm and thus decreases with increasing spread also the moment of force causing the expansion. At the point where the direction of force passes through the Joint point, the value of the moment of force becomes zero. If the hinge point is even undershot, the direction of rotation of the moment of force is reversed and causes a reduction in what has been achieved up to that point Spreading angle. The anchor according to the main patent can therefore not be fully expanded. Nevertheless, there is an angle of spread between the two Half-shells of around 90 are possible, which is far above what has been achieved with the known dowels could be.

Dem Zusatzpatent liegt daher die Aufgabe zugrunde, das Hauptpatent in dieser Hinsicht zu verbessernThe additional patent is therefore based on the task of improving the main patent in this regard

und einen noch größeren Aufspreizwinkel des Dübels möglich zu machen.and to make an even larger spreading angle of the anchor possible.

Erfindungsgeir.äß wird dies dadurch erreicht, daß die freien Schenkel von dem Punkt ab, an dem 4as die Aufspreizung bewirkende Kraftmoment für eine weitere Aufspreizung zu gering ist, gegen die als Gelenkpunkte dienenden Stege hin abgeschrägt sind.According to the invention, this is achieved in that the free leg from the point at which 4as the force moment causing the expansion for another Spreading is too small, against which webs serving as hinge points are beveled.

Durch die gegen die als Gelenkpunkte dienenden Stege gerichtete Abschrägungen der freien Schenkel wird der von der Kraftrichtung und der Längsachse des Dübels eingeschlossene Winkel wieder vergrößert, wodurch gleichzeitig auch der Hebelarm und damit das die Aufspreizung bewirkende Kraftmoment vergrößert wird. Damit kann durch die erfindungsgemäße Lösung der Aufspreizwinkel bis nahezu 180 gesteigert werden. Durch die größere Menge des von den stärker aufgespreizten Schenkeln hintergriffenen Materials wird I somit eine Erhöhung des Ausziehwiderstandes des Dübels erreicht.Due to the bevels of the free legs directed against the webs serving as hinge points, the from the direction of force and the longitudinal axis of the anchor included angles increased again, whereby at the same time the lever arm and thus the force moment causing the spreading is increased. With the solution according to the invention, the spread angle can thus be increased to almost 180. Due to the larger amount of the more widely spread The legs of the material engaged behind will thus increase the pull-out resistance of the Dübels reached.

Der durch das Zusatzpatent verbesserte Dübel macht durch seinen nahezu 180 erreichbaren Aufspreizwinkel auch einen Einsatz des Dübels möglich, bei dem dieser nicht in der Wand verankert, sondernThe dowel, which has been improved by the additional patent, makes it possible to achieve a spreading angle of almost 180 It is also possible to use the dowel in which it is not anchored in the wall, but

Nach einem w.eiteren Merkmal der Erfindung können die Eckpunkte der abgeschrägten freien Schenkel abgerundet sein. Damit wird ein plötzlicher Wechsel der Kraftrichtung vermieden, der zu einer Spannungsspitze und damit unter Umständen zum Bruch des Befestigungselementes führen könnte.According to a further feature of the invention, the corner points of the beveled free legs be rounded. This avoids a sudden change in the direction of force leading to a stress peak and thus could lead to breakage of the fastening element under certain circumstances.
