Abstract

The plug or dowel has the advantage that it does not rely solely on the tension force between the plug and the side of the hole for its load carrying capability. As the plug is inserted an internal conical hole is bored with a lesser cross section than the cone itself at the end of the hole. The cone forms the spreaders of the plug into a conical shape to form an anchor for the shaft. The cone is connected to the plug shaft when it is in the fully home position.

PATENTBEbCHREIBUNGPATENT DESCRIPTION

Betr.: üelbstbohrender InnenkegeldubelRe: self-drilling inner cone dowel

Bekannt sind selbstbohrende Dübel. Diese Dübel bohren ein zylindrisches Dübelloch. Nach dem Bohren werden diese Dübel mit einem Kegel bestückt und in das Dübelloch eingeschlagen, wobei sich der Dübel in dem zylindrischen Bohrloch festkeilt. Die opannung zwischen dem Dübel und der Lochleibung ist maßgebend für die Belastbarkeit des Dübels.Self-drilling dowels are known. These dowels drill in cylindrical dowel hole. After drilling, these dowels are fitted with a cone and hammered into the dowel hole, wherein the dowel wedges itself into the cylindrical borehole. The tension between the dowel and the embedment is decisive for the load capacity of the anchor.

Bei vorliegender Patentanmeldung handelt es sich um einen Dübel, der in ein zylindrisches Bohrloch eingesetzt wird, und beim Einsetzen sich eine Innenkegellochleibung bildet, wobei der größere Durchmesser der Innenkegelbohrung am Ende der Bohrung entsteht. Die beim Einsetzen des Dübels bohrenden und spreizenden Spannteile werden über einen Führungs- und Spannkegel geführt. Nach der Herstellung des Innenkegels verbindet sich der Führungs- und Spannkegel mit dem Schaft des Dübels durch Verschraubung oder Klemmwirkung. Der Führungs- und Spannkegel erzeugt über die Spreizen des Dübels keinen Druck auf die Lochleibung der Innenkegelbohrung. Der Gesamtkegel des Dübels wird durch das Einbeziehen des Führungs- und Spannungskegels so verformt, daß die Außenflächen des Dübels bündig auf♦Innen- *die kegellochleibung der Dübelbohrung aufliegen und der Dübel als Ganzes ein Anker bildet.The present patent application is a dowel that is inserted into a cylindrical borehole, and When inserting an inner cone hole embedment is formed, the larger diameter of the inner cone hole at the end of the Bore is created. The clamping parts that drill and expand when inserting the dowel are made via a guide and clamping cone guided. After the inner cone has been produced, the guide and clamping cone connects to the shank of the dowel by screwing or clamping effect. The guide and clamping cone does not generate any pressure on the dowel through the expansion Embedment of the inner cone bore. The overall cone of the anchor is created by including the guide and tension cone deformed so that the outer surfaces of the dowel are flush with the ♦ inner * the the conical hole reveal of the dowel hole and the dowel as a whole forms an anchor.

Figur I zeigt einen selbstbohrenden Innenkegeldubel vor dem Einsetzen. Die Bohr- und Spreizteile (1) liegen auf dem spitzen Teil des Führungs- und Spannkegels (2). Der Führungs- und Spannkegel (2) weist an der Spitze ein Gewinde (3) auf. Das Fußende des Führungs- und Spannkegels erhält ein Händel oder ist als Keil (4) ausgebildet. Die Länge der Schraubhülse (5) und der Spreizen (1) ist je nach Verwendung verschieden. Figure I shows a self-drilling inner cone dowel before insertion. The drilling and expanding parts (1) lie on the pointed part of the guiding and clamping cone (2). The guide and clamping cone (2) has a thread (3) at the tip. The foot end of the guiding and clamping cone is handled by a hand or is designed as a wedge (4). The length of the screw sleeve (5) and the spreaders (1) differ depending on the use.

Figur II zeigt einen selbstbohrenden Innenkegeldubel nach den Einsetzen.Fi gur II shows a self-drilling inner cone dowel after the insertion.
