Patentbesehreibungt Patent description t

Die Verwendung von Befestigungsdübela nimmt, in der Bauindustrie und im Haushalt, immer grosser en Umfang an. Datei kann man feststellen} dass sich das Angebot an Spreizdübel in allen Variationen auf ein Prinzip stützt. Durch Ausspreizung eines Hülsenankers wird •in Konus hergestellt, der auf Zug belastbar ist.The use of fixing dowels is increasing in the construction industry and in the household, increasingly large. File can be determined} that the range of expansion dowels in all variations is based on one principle. By spreading out a sleeve anchor • Manufactured in a cone that can withstand tension.

Diese, von mir zu Patent angemeldete Erfindung weicht dadurch grundsätzlich von diesen Prinzip ab, dass derThis invention, for which I have applied for a patent, fundamentally gives way from this principle that the

sowohl auf Zug, wie auf Druck belastet werden kann. Die Dübelhülse ist zweiteilig gearbeitet und erhält im Teil B ein Innengewinde. Der Teil A ist in der lichten leite so groß gehalten, dass er die Zugschraube aufnehmen kann. Seil A und feil B sind krallenartig ausgebildet. Diese Krallen liegen im Normalzustand flach an. Sobald der Dübel im passenden Bübelloch eingssetzt ist, wird die Zugsahraube angezogen· Dabei schieben sich die beiden Hülsenteile A gegen B und die Krallen werden durch die schräg gefrästen Gleitbahnen nach aussen geleitet und krallen sich im Mauerwerk fest« Je nach Länge der Krallen stechen dieselben ins Mauerwerk ein oder si· rollen sich auf, ao&&sa die Dübelhülse in beiden Zugrichtungen fest, fixiert ist.can be loaded on both train and pressure. The dowel sleeve is made in two parts and has an internal thread in part B. Part A is kept so large in the clear line that it has the Can accommodate lag screw. Rope A and Feil B are claw-like educated. These claws lie flat in the normal state. As soon the dowel is inserted in the matching girder hole, the Pulling hood tightened · The two parts of the sleeve A slide against B and the claws move through the diagonally milled slideways directed to the outside and cling to the masonry " Depending on the length of the claws, they pierce or pierce the masonry si · roll up, ao && sa the dowel sleeve in both directions of pull firmly, is fixed.

Als weiteren Verteil ergibt sich dabei, dass die Position der Zugschraube während des Befestigung*vorganges unverändert bleibt, sodas s ein Vorsetzten der Schraube nicht mehr erforderlich ist. Die Zugschraube kann jederzeit gelöst und neu angezogen werden, weil der „ Doppelkrallen&preizdübel" nach der Montage seine feste Verankerung in Mauerwerk nicht mehr verliert,Another distribution is that the position of the tension screw remains unchanged during the fastening process, so that s it is no longer necessary to advance the screw. the The lag screw can be loosened and retightened at any time because the "double claws & preizdübel" is firmly anchored after assembly no longer loses in masonry,
