Description
Gegenstand der Erfindung ist ein durch Außenbewehrung versteifter Faserstoffstrangdübel, der einerseits nicht seitlich ausbauchen kann, andererseits billig herzustellen ist. Beim Einführen des Befestigungsmittels (Nagel, Schraube) wird der Faserstoffstrang in seiner Längsrichtung zusammengeschoben. Dabei biegt er die außenliegenden Versteifungsschienen auseinander. Leisten diese dem Drucke The subject of the invention is a fiber rod dowel stiffened by external reinforcement, which on the one hand cannot bulge out laterally, on the other hand it is cheap to manufacture. When inserting the fastener (nail, screw), the fiber strand is in pushed together in its longitudinal direction. In doing so, he bends the outer stiffening rails apart. Do this to the pressure
ίο ungleichmäßig Widerstand, so quillt die Faserstoffmasse einseitig heraus, und das Befestigungsmittel weicht von der beabsichtigten Mittellage ab. Man hat einen gleichmäßigen Widerstand bereits dadurch erzielt, daß man 'einen U-förmigen Blechstreifen um den Strang der Länge nach legt. Die Verbindung der beiden Schenkel am Ende des Dübels gab hierbei den Schienen den erforderlichen Halt. Diese Ausführungsform ist jedoch in der Herstellung teuer.ίο uneven resistance, the pulp mass swells out on one side, and the fastening means deviates from the intended central position. You have a steady one Resistance already achieved by 'a U-shaped sheet metal strip around the strand lays lengthwise. The connection of the two legs at the end of the dowel gave the Rails the necessary support. However, this embodiment is under construction expensive.
Man hat nun die Kosten dadurch herabgesetzt, daß man, statt einen Blechstreifen der Länge nach U-förmig um den Dübel zu legen, einen Blechstreifen seitlich um den Strang her-The cost has now been reduced by using the Place a U-shaped length around the dowel, put a metal strip around the side of the strand.
2,5 umrollte, der dabei einen offenen Längsschlitz behielt. Die Faserstoffüllung zeigte dabei das Bestreben, nach der Seite des Schlitzes auszubauchen. Rolldübel dieser Art waren deshalb zwar billiger in der Herstellung, jedoch in der Wirkungsweise den U-förmigen Dübeln unterlegen. 2.5 rolled, which kept an open longitudinal slit. The fiber filling showed the tendency to bulge towards the side of the slot. Rolling dowels of this type were therefore cheaper to manufacture, but inferior to U-shaped dowels in terms of their mode of action.
Nach der Erfindung wird nun ein gleichmäßiger Aufweitungswiderstand der Dübelhülle dadurch erzielt, daß zwei Blechstreifen den Faserstoffstrang umhüllen, die so breit gewählt sind, daß sie sich gegenseitig symmetrisch überlappen. Die Überlappung gibt dem Faserstoff den erforderlichen Halt zum Einführen, sie hält den Strang während des Dübelvorganges selbst und bietet einen gleichmäßigen Aufweitungswiderstand dadurch, daß beim Auftauchen des Stranges die übereinandergreifenden Blechhüllen an den Überlappungsstellen auf der ganzen Länge des Dübels gleichmäßig aufgeweitet werden müssen.According to the invention, there is now a uniform expansion resistance of the anchor sleeve achieved in that two metal strips envelop the fiber strand, which is chosen as wide are that they overlap each other symmetrically. The overlap gives the pulp the necessary hold for insertion, it holds the strand itself during the dowelling process and offers a uniform expansion resistance in that when the surface of the Strands the overlapping sheet metal sleeves at the overlap points on the must be widened evenly over the entire length of the dowel.
Dübel nach der Erfindung besitzen aber besonders den Vorteil, daß gleichzeitig die beiden Blechstreifen mit dem Faserstorfstrang zusammen zwangsweise durch eine Düse gezogen werden können, so daß sie in einem einzigen Arbeitsgang endlos und kalibriert wie Röhren nach dem an sich bekannten Ziehverfahren hergestellt werden können.Dowels according to the invention have the particular advantage that the two at the same time Sheet metal strips are forcibly pulled together with the fiber strand through a nozzle so that they are endless and calibrated like tubes in a single operation can be produced by the drawing process known per se.
In der Zeichnung bedeuten a1 und a- die äußere und die innere Blechhülle, welche den Faserstoffstrang b in sich gegenseitig gleichmäßig überlappender Weise umhüllen. Beim axialen Zusammentreiben des Faserstoffstranges b muß die Dübelhülle sich gleichmäßig aufweiten, so daß der Faserstoffstrang nicht nach einer Seite ausbauchen kann.In the drawing, a 1 and a- denote the outer and inner sheet-metal casing, which envelop the fiber strand b in a mutually uniformly overlapping manner. When the fiber strand b is axially driven together, the dowel casing must expand evenly so that the fiber strand cannot bulge out to one side.
Es sind auch andere Ausführungsmöglichkeiten vorhanden. Das Wesen der Erfindung besteht stets darin, daß zwei Blechstreifen einen Faserstoffstrang dadurch halten, stützen, versteifen und gleichmäßig aufweitbar sind, daß sie sich der Länge nach symmetrisch um den Faserstoffstrang überlappen.There are also other design options available. The essence of the invention always consists in the fact that two metal strips hold, support and stiffen a fiber strand and are evenly expandable so that they are symmetrically about the length Overlap the fiber strand.
