Bolzendübel für Brett-Querverbindung, insbesondere der Elemente einer Platte Beschreibung Die vorliegende Neuerung betrifft einen Bolzendübel zur Verbindung von Brettern oder Bohlen zu einer Platte.Bolt dowels for board cross-connection, in particular of the elements of a Plate Description The present innovation concerns a bolt dowel for connection from boards or planks to a plate.

Die Neuerung des Bolzendübels besteht darin, daß er aus Hohl-Röllchen oder Hohl-Stäbe gefertigt wird. Der Dübel kann im Querschnitt rechteckige kreisrund, polygon oder oval sein. The innovation of the bolt dowel consists in the fact that it consists of hollow rollers or hollow rods is manufactured. The anchor can be rectangular circular in cross section, be polygon or oval.

Die Hohlstäbe werden seitlich gezahnt, die Hohlrollchen gerillt, wie bereits vorbekannt. The hollow rods are serrated on the side, the hollow rollers are grooved, as previously known.

Vorzüge: Der Vorzug des Hohlmaterials gegenüber Voll-material ist bereits bekannt und zwar hat Hohlmaterial eine unvergleichlich größere Biegefestigkeit als Vollmaterial. (Bei Röhren. wird mit der 4-fachen Festigkeit gegenüber vollmaterial gerechnet).Advantages: The advantage of hollow material over solid material is already known and hollow material has an incomparably greater flexural strength as solid material. (In the case of tubes, with 4 times the strength compared to solid material expected).

Die Wirtschaftlichkeit des Hohl-Dübels ist infolge Gewichts-Einsparung zweifellos gegeben. The economy of the hollow dowel is due to the weight saving undoubtedly given.
