Abstract
Description
Der Erfindung liegt die Aufgabe zugrunde einen Dübel für harte Körper wie Beton Stein etc. zu schaffen, der sich selbst im Bohrlochgrund eine konische Ausnehmung gräbt, um so bei auftretenden Rissen im gesetzten Material noch einen Halt zu garantieren. Derartige Dübel sind bekannt.The invention has for its object a dowel for hard bodies like concrete, stone, etc., which creates a hole in the bottom of the borehole tapered recess digs so as to occur when cracks occur in the Material still guarantee a hold. Such dowels are known.
Sie haben aber den Nachteil, daß sie nur sehr aufwendig hergestellt werden können. Entweder weisen sie eine Schneidhülse oder einen Schneidring auf.However, they have the disadvantage that they are produced only with great effort can. They either have a cutting sleeve or a cutting ring on.
Der erfundene Dübel braucht diese zusätzlichen Schneidvorrichtungen nicht. Sein Material ist im Bereich der Schneidkanten 1 und 2 derart gehärtet, daß es beim Überstülpen des Dübels 3 über den Flachkonus 4 sich im zu befestigenden Material die gewünschte Ausnehmung leicht schafft. Der übrige Teil des Dübels 3 bleibt zumindest im Gewindebereich 5 und Schlitz bereich 6 so elastisch, daß das Gewinde eine Biegung und der Dübel im Schlitzbereich eine Aufbiegung aushält ohne zu brechen, was nicht der Fall wäre, wenn der Dübel überall so hart wäre, wie es an den Schneidkanten notwendig ist, damit der Dübel sich konisch in den Untergrund eingräbt.The invented dowel does not need these additional cutting devices. Its material is hardened in the area of the cutting edges 1 and 2 in such a way that when the dowel 3 is slipped over the flat cone 4 , the desired recess is easily created in the material to be fastened. The remaining part of the dowel 3 remains at least in the threaded area 5 and slot area 6 so elastic that the thread can withstand a bend and the dowel in the slot area can bend without breaking, which would not be the case if the dowel were everywhere as hard as it is necessary at the cutting edges so that the dowel digs conically into the ground.
Der Flachkonus 4 verfügt über zwei Lappen 7, die in den Schlitz 8 ein greifen, wodurch verhindert wird, daß sich der Konus verdreht, er bleibt somit arretiert und garantiert die Aufspreizung. Der zylindrische Ansatz 9 des Flachkonus 4 greift in die Bohrung 10 des Dübels 3 unter Spannung, wodurch eine Zentrierung beim Eintreiben erreicht wird. Die Breite B des Flachkonus ist so bemessen, daß sie weniger als ein Drittel des Außen durchmessers des Dübels 3 ausmacht. Dadurch wird gewährleistet, daß das anfallende Mehl des Untergrunds beim Aufspreizen leicht abfließen kann. Deshalb kann die Breite A des Flachkonus fast den Durchmesser des Dübels 3 erreichen, wodurch eine maximale Aufspreizung möglich ist.The flat cone 4 has two tabs 7 which engage in the slot 8 , thereby preventing the cone from twisting, so it remains locked and guarantees spreading. The cylindrical extension 9 of the flat cone 4 engages in the bore 10 of the dowel 3 under tension, whereby centering is achieved when driving in. The width B of the flat cone is such that it makes up less than a third of the outer diameter of the dowel 3 . This ensures that the flour of the substrate can easily drain off when spreading. Therefore, the width A of the flat cone can almost reach the diameter of the dowel 3 , whereby a maximum spreading is possible.
Die Fig. II zeigt einen Dübel, der im Gegensatz zu dem in der Fig. I gezeigten ein Innengewinde aufweist. Im übrigen ist dieser Dübel genau so aufgebaut, wie der unter Fig. I. Allerdings kann der Dübel unter der Fig. II nicht nur aus Vollmaterial hergestellt sein, sondern, auch wie das Bild es zeigt, aus gerilltem Band gefertigt werden, das an der Kante 11 zusammenstößt. Dieser Stoß bildet dann etwas aufgeweitet im Spreizbe reich einen Teil des Gesamtschlitzes 8. FIG. II shows a dowel which, in contrast to the one shown in FIG. I, has an internal thread. Otherwise, this dowel is constructed exactly as that under Fig. I. However, the dowel under Fig. II can not only be made of solid material, but also, as the picture shows, made of grooved tape attached to the Edge 11 collides. This joint then forms somewhat expanded in the Spreizbe rich part of the total slot 8th
