Description

K onua s] ß. r e 1 z dL b, 8, l Gegenstand der Erfindung betrifft einen Konusspreizdübel zum \ Befestigen von Gegenständen im Mauerwerk od. dgl. Konusspreiizdubel, die zum Befestigen von Gegenständen im Mauer- werk dienen, die aus einer Befestigungsschraube, einer aus thermoplastischen Kunststoff hergestellten, mit Längsnuten versehenen Spreizhülse und einer ans Metall oder auch aus Kunststoff hergestellten konischen Mutter, die beim Anziehen der Befestigungsschraube zugleich die Funktion eines Spreizmittels Obernimmt, wodurch die Oberfläche der Spreizhülse fest an die Lochwandung des Mauerwerks angepresst wird, besteht, sind bereits bekannt. Bei höheren Umgebungstemperaturen des Konusspreizdübels ist es auch schon bekannt, die Spreizhülse aus härtbarem Kunststoff herzustellen. K onua s] ß. re 1 z dL b, 8, l The invention relates to a cone expansion anchor for \ Fixing objects in the masonry or the like. Conical dowels, which are used to fasten objects in the wall work, which consist of a fastening screw, an expansion sleeve made of thermoplastic material, provided with longitudinal grooves and a conical nut made of metal or plastic, which when tightening the fastening screw also takes on the function of an expansion means, whereby the surface of the expansion sleeve is firmly attached to the Hole wall of the masonry is pressed, exists, are already known. At higher ambient temperatures of the conical expansion anchor, it is already known to produce the expansion sleeve from hardenable plastic.

Um jedoch den Konusspreizdübel rationeller herzustellen und preislich günstiger auf den Markt zu bringen, wird erfindungsgemäss vorgeschlagen, das aus Kunststoff hergestellte Spreizmittel mit der Spreizhülse aus einem Stück bzw, aus dem gleichen Material in einem Arbeitsgang in der Weise herzustellen, als die Spreizhülse und das Spreizmittel durch eine dünne Haut miteinander verbunden werden, die, beim Anziehen der Befestigungsschraube abreisst und das Spreizmittel von der Befestigungsschraube in die Spreizhülse hineingezogen wird, so dass die Oberfläche derselben fest an die Lothwandung des Mauerwerks angepresst wird. Damit das konische Spreizmittel beim Anziehen der Befestigungsschraube sich nicht mitdrehen kanne erhält das Spreizmittel an seiner Oberfläche zwei oder mehrere Rippen, die in die Längsschlite der Spreizhülse eingreifen. Dadurch, dass das konische Spreizmittel aus Kunststoff, wie die Spreizhülse selbst, hergestellt wird, ist es möglich, dass dasselbe wahlweise als Mutter mit gewinde zum Einschrauben von Befestigungsschrauben aller Art vorgesehen wird. In der Zeichnung ist ein Ausführungobeispiel des Erfindungs- gegenstandes dargestellt.However, in order to produce the conical expansion dowel more efficiently and to bring it to the market at a lower price, the invention proposes that the expansion means made of plastic with the expansion sleeve be made from one piece or from the same material in one operation in the same way as the expansion sleeve and the expansion means are connected to each other by a thin skin, which tears off when the fastening screw is tightened and the expansion means is drawn into the expansion sleeve by the fastening screw, so that the surface of the same is pressed firmly against the solder wall of the masonry. So that the conical expansion means cannot rotate when the fastening screw is tightened, the expansion means has two or more ribs on its surface which engage in the longitudinal slides of the expansion sleeve. Because the conical expansion means is made of plastic, like the expansion sleeve itself, it is possible that it is optionally provided as a nut with a thread for screwing in fastening screws of all kinds. In the drawing is an exemplary embodiment of the invention object shown.

Abb. 1 zeigt die Vorderansicht der aus einem Stück und in eine. Arbeitsgang hergestellten Spreizhülse und dem darunter liegenden und mit ihr durch eine liaut verbundenen Spreizmittel Abb. 2 den Längsschnitt A-B anch Abb. 1 und Abb. 3 die Vorderansicht von Spreizhülse und Spreizmittel, wobei letzteres mit Gewinde für Holzschrauben versehen ist.Fig. 1 shows the front view of the one-piece and in a. Operation produced expansion sleeve and the one below and with her by a liaut associated spreading means Fig. 2 the longitudinal section AB and Fig. 1 and Fig. 3 the front view of the expansion sleeve and expansion means, the latter being provided with a thread for wood screws.

Das unter der Spreizhülse liegende mit Rippen 5 versehene Spreizmittel 1 ist durch die dünne Haut 2 mit der Spreizhülse 3, die mit Längsschlitzen 4 versehen ist, verrunden, Nach Abb. 3 ist das Spreizmittel 1 mit Gewinde für Holzschrauben versehen, in welches die holzschraube 6, die zum Befestigen des Gegenstandes 7 am Mauerwerk dient, eingeschraubt sit, die Haut 2 also schon abgerissen, das Spreizmittel 1 in die Sprezhülse 3 durch die Befestigungssehraube hineingezogen, wodurch das untere Ende der Spreizhülse 3 auseinandergespreizt wird. Die Rippen 5 bewegen sich in den Schlitzen 4, wodurch ein Drehen des Spreizmittels 1 unmöglich istThe expansion means provided with ribs 5 under the expansion sleeve 1 is through the thin skin 2 with the expansion sleeve 3, which is provided with longitudinal slots 4 is, round, According to Fig. 3, the expansion means 1 is threaded for wood screws provided, in which the wood screw 6, which is used to attach the object 7 to the Masonry is used, screwed in, so the skin 2 has already been torn off, the expanding agent 1 pulled into the sprez sleeve 3 through the fastening tube, whereby the the lower end of the expansion sleeve 3 is spread apart. The ribs 5 move in the slots 4, whereby a rotation of the expansion means 1 is impossible
