Abstract

Rotation of the external nut causes spreading of a sleeve under the inward pressure of cones at each end of the dowel shank. On the outer end of the dowel under the nut and associated washer is fitted a readily deformable pot-shaped spacer which upon insertion of the dowel provides a definite clearance between the nut and washer and the face of the material through which the dowel passes. Sleeve has diverging tapered ends, and pot shaped washer is very thin.

" Parallelste izdübel""Parallel most izdowels"

Unter Parallelspreizdübel versteht man Dübel bei denen die Dübelsegmente oder die Dübelhülse nicht nur am unteren Ende an die Bohrlochwandung sondern auf der ganzen Länge gepresst wird. Die Erfindung betrifft einen Dübel, bei dem eine Konusmutter am Bohrlochende und eine Konushülse am Lochanfang angeordnet ist. Beim Anziehen zieht sich die Konusmutter in die DUbel-hülse und um eine parallele Spreizung zu erzielen, muß sich die Konushülse genausoweit in die Dübelhülse ziehen. Dies kann jedoch nur erfolgen, wenn der Dübel beim Spreizbeginn um ein gewisses Maß aus dem zu befestigenden Teil und zwar je nach Dübelgröße heraussteht. Man hat sich bisher damit geholfen, daß der erforderliche Abstand geschätzt wurde, oder daß man Maßsteine unter die Unterlagscheibe legte, wobei das erste sehr ungenau ist und das zweite sehr umständlich ist. Es ist auch ein Dübel bekannt, bei dem die Unterlagscheibe gewölbt ist. Insofern als diese Unterlagscheiben von der Konstruktion her sehr stark sein müssen, kann eine allzu hohe Wölbung nicht erzielt werden. Wie in Abbildung 1 ersichtlich, wird dadurch auch nur eine Distanz vom Maß A erzielt, was bei der Dübelgröße M 12 zum BeispielParallel expansion dowels are dowels in which the dowel segments or the dowel sleeve is not only pressed against the borehole wall at the lower end but along its entire length. The invention relates to a dowel in which a conical nut on Borehole end and a conical sleeve is arranged at the beginning of the hole. When tightening, the conical nut pulls into the DUbel sleeve and in order to achieve a parallel expansion, the conical sleeve must pull itself into the dowel sleeve to the same extent. However, this can only take place if the dowel is a certain amount out of the part to be fastened at the start of expansion, depending on the dowel size stands out. So far one has helped that the required distance was estimated, or that one under measuring stones put the washer, the first being very imprecise and the second very cumbersome. It is also known a dowel, in which the washer is curved. Inasmuch as these washers are very strong by design too high a curvature cannot be achieved. As can be seen in Figure 1, this also only adds a distance from dimension A, which is the case with dowel size M 12, for example

Die Erfindung betrifft einen Dübel entsprechend der Abbildung 2. Unter der Unterlagsscheibe;1 ist eine sehr dünne und aua leicht verformbarem Material hergestellte Tellerscheibe 2 angeordnet,
deren Höhe entsprechend dem geforderten Abstandsmaß gewählt ist. Beim Anziehen des Dübels drückt sich diese Tellerscheibe 2

the height of which is selected according to the required spacing. When the dowel is tightened, this washer 2 is pressed
flat and presses with the washer 1 on the part to be fastened.
