Description
Metallstreifen zur Herstellung von in Mauerwerklöchern einsetzbaren Dübeln Die vorliecende Erfindung betrifft einen biegsamen MetallstreUen zur Herstellung von in MauerwerkWehern einsetzbaren Dübeln, weleher dadurch gekennzeichnet ist, dass er ein Flaehrillenprofil. aufweist, dessen konkave Innenseite mit rippenförmigen Erhöhungen \-ersehen ist, und dass er in regelmässigen<B>Ab-</B> ständen geloeht ist,
wobei auf der konvexen Aussenseite die Löcher von kragenförmigen Erhöhun,gen umgeben sind.
Ausführun-s- und Anwendungsbeispiele des Erfindungsgegenstandes sind in der Zeich- ilun- dar-estellt. Darin zeigen: ell <B>--</B> F!,-.<B>1-</B> und 2 die Draufsieht auf die kon kave Innenseite<B>je</B> eines Ausführungsbeispiels des 'Metallstreifens zür Herstellung von Dü- beln, F ig. <B>3</B> einen Längssehnitt nach der Linie 111-III von Fig. <B>1,
</B> Fig. 4 einen Querschnitt nach der Linie IV-IV von Fig. <B>1,</B> Fig-. <B>5</B> einen Querschnitt nach der Linie V-V von Fig. 2, Fig. <B>6</B> eine erste Anwendungsart und Fig. <B>7</B> eine zweite Anwendungsart des Streifens.
Der bandförmige Metallstreifen<B>1</B> gemäss Fig. <B>1, 3</B> und 4 besteht beispielsweise aus Rein- aluminium, hat ein Flachrillenprofil, und des sen konkave Innenseite ist mit rippenförmigen Erhöhun-en 2 versehen. Die Rippen 2 stehen etwas schräg zur Längsriehtung -und dieser Sehrä-Winkel und die Abstände zwischen die- sen Rippen entsprechen der mittleren Ge windesteigung von Holzschrauben.
In regelmässigen Abständen ist das Band material mit Löchern 4 versehen, die auf der konvexen Aussenseite von kragenförmigen Er höhungen<B>5</B> umgeben sind. Auch auf der Aussenseite des Streifens sind gewindeförmige Erhöhungen<B>9</B> vorgesehen.
Der Streifen gemäss den Fig. 2 und<B>5</B> unterscheidet sieh vom vorigen im wesentlichen dadurch, dass die Erhöhungen<B>3</B> in der Längs- riehtung des Streifens verlaufen.
Zur Herstellung von Mauerdübeln wird der Streifen in Teilstücke zerschnitten, diese an einer Lochstelle umgebogen und nach Fig. <B>6</B> in ein Mauerwerkloch <B>6</B> eingesteckt. Mittels einer eing-esehraubten Holzschraube<B>7,</B> deren Gewinde in den Rippen 2 Halt findet oder sich in die Rippen<B>3</B> (Fig. 2,<B>5)</B> einschneidet, werden diese Stücke aufgespritzt, wobei sich die kragenförmigen Erhöhungen<B>5</B> und die Erhöhungen<B>9</B> in der Wandung des Mauer- werkloches versperren.
In Fig. <B>7</B> ist ein Dübel dargestellt, der aus einem längeren Bandstreifenstilek herge stellt ist, der zuerst an Stelle eines Loches umgebogen wurde und dessen Sehenkelenden dann wieder zurüekgebogen sind. Dabei dienen die Rippen 2 zur Verankerung des Dübels im Mauerwerk.
In beiden Fällen von Fig. <B>6</B> und<B>7</B> dringt die Spitze der Schraube<B>7</B> in das Loch 4 der Hauptbiegestelle ein,
Metal strips for producing dowels that can be used in masonry holes The present invention relates to a flexible metal litter for producing dowels that can be used in masonry holes, which is characterized in that it has a flat groove profile. has, whose concave inside is seen with rib-shaped elevations, and that it is perforated at regular <B> intervals </B>,
whereby on the convex outside the holes are surrounded by collar-shaped elevations.
Embodiments and application examples of the subject matter of the invention are shown in the drawing. It shows: ell <B> - </B> F!, -. <B> 1- </B> and 2, which looks at the concave inside <B> each </B> of an exemplary embodiment of the metal strip Manufacture of dowels, fig. <B> 3 </B> a longitudinal section along the line 111-III from FIG. <B> 1,
FIG. 4 shows a cross section along the line IV-IV from FIG. 1, FIG. 5 shows a cross-section along the line V-V of FIG. 2, FIG. 6 shows a first type of application and FIG. 7 shows a second type of application of the strip.
The band-shaped metal strip <B> 1 </B> according to FIGS. 1, 3 and 4 consists for example of pure aluminum, has a flat groove profile, and its concave inside is provided with rib-shaped elevations 2 . The ribs 2 are slightly oblique to the longitudinal direction - and this visual angle and the distances between these ribs correspond to the mean thread pitch of wood screws.
The tape material is provided with holes 4 at regular intervals, which are surrounded on the convex outside by collar-shaped elevations <B> 5 </B>. Threaded elevations <B> 9 </B> are also provided on the outside of the strip.
The strip according to FIGS. 2 and 5 differs from the previous one essentially in that the elevations 3 run in the longitudinal direction of the strip.
To produce wall dowels, the strip is cut into pieces, bent over at a hole point and inserted into a masonry hole <B> 6 </B> as shown in FIG. 6. By means of a screwed-in wood screw <B> 7 </B> whose thread is held in the ribs 2 or in the ribs <B> 3 </B> (Fig. 2, <B> 5) </B> cuts in, these pieces are sprayed on, with the collar-shaped elevations <B> 5 </B> and the elevations <B> 9 </B> blocking one another in the wall of the masonry hole.
In Fig. 7, a dowel is shown which is made from a longer tape strip style that was first bent over in place of a hole and the ends of which are then bent back again. The ribs 2 are used to anchor the anchor in the masonry.
In both cases of FIGS. 6 and 7 the tip of the screw 7 penetrates into the hole 4 of the main bending point,
