Description
Rahmenverbindung für Türen und ähnliche Rahmengebilde mit in Ausnehmungen der Rahmenhölzer liegenden Spreizdübeln Rahmenverbindungen mit in Ausnehmungen der Rahmenhölzer liegenden Spreizdübeln sind bereits bekannt. Hierbei hatten die Ausnehmungen die Form eines Zylinders mit ebenem Grunde. Das genaue Ausarbeiten der scharfen Ecken am Grunde, das für das Einpassen des Dübels erforderlich ist, wär zeitraubend und umständlich; zudem war die Verwendung von Spreizdübeln runden Querschnitts bei schwachen Holzteilen nicht angängig. Die vorliegende Erfindung hilft hier ab, indem die Ausnehmungen rechteckigen Querschnitt mit halbkreisförmiger Abrundung am Grunde erhalten und als Spreizdübel ein Flachdübel verwendet wird, der sich auch mit seinen Abrundungen an den Enden in die Ausnehmungen der Rahmenhölzer satt einlegt. Eine derartige Rahmenverbindung ist leicht und billig herzustellen und insbesondere auch für schwache Rahmenhölzer brauchbar.Frame connection for doors and similar frame structures with recesses the frame timber lying expansion dowels frame connections with recesses in the Expansion dowels lying on frame wood are already known. Here the recesses had the shape of a cylinder with a flat base. The exact elaboration of the sharp Corners at the bottom, which is required for fitting the dowel, would be time consuming and awkward; In addition, the use of expansion dowels with a round cross-section was included weak wooden parts are not acceptable. The present invention remedies this by the recesses have a rectangular cross-section with a semicircular rounding at the bottom obtained and a flat dowel is used as an expansion dowel, which also works with his Fill in the rounding at the ends in the recesses of the timber frame. One Such a frame connection is easy and cheap to manufacture and in particular also usable for weak frame timbers.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigen Abb. i eine Draufsicht auf eine Rahmenverbindung, Abb. a einen Schnitt nach A-B deY Abb. i und Abb. 3 eine Draufsicht auf den Spreizdübel. Der Längsrahmen a mit der Ausnehmung c wird mit dem Querrahmen b mit der Ausnehmung d durch den Spreizdübel e mit den Einschnitten/ und .g und den Keilen h und i in folgender Art verbunden: In die Rahmenhölzer a und b werden, nachdem sie vorher stumpf oder im Gärungsschnitt zusammengepaßt worden sind, z. B. durch einen ,Kettenfräser, die Ausnehmungen c und d eingefräst. Hierauf wird der flache, die Ausnehmungen genau ausfüllende Spreizdübel,e, nachdem vorher in die Keileinschnitte f undg die Keile h und i eingeklemmt und das Ganze in Leim eingetaucht worden ist, mit seinen Enden in die Ausnehmungen c und d der Rahmen a und b eingeschoben, worauf letztere mit starkem Druck gegeneinandergepreßt werden.In the drawing, the invention is shown in an exemplary embodiment, namely Fig. I shows a plan view of a frame connection, Fig. A shows a section according to AB deY Fig. I and Fig. 3 shows a plan view of the expansion dowel. The longitudinal frame a with the recess c is connected to the transverse frame b with the recess d by the expansion dowel e with the incisions / and .g and the wedges h and i in the following way: In the frame timbers a and b after they are butted beforehand or have been matched in the fermentation cut, e.g. B. by a, chain cutter, the recesses c and d milled. Then the flat expansion dowel, e, which exactly fills the recesses, is inserted with its ends into the recesses c and d of the frames a and b after the wedges h and i have previously been clamped into the wedge incisions f and g and the whole has been dipped in glue , whereupon the latter are pressed against each other with strong pressure.
