Abstract

Expansion anchor has an expansion sleeve (2) which is fitted between the tapered part (3) and the head (5) of the stud (1) to cover the shank of stud. The head of the stud is inserted in the slot (8) of a washer (7).

Description

Die Erfindung macht sich zur Aufgabe einen preiswerten Spreizdübel für vorwiegend harte Körper wie Beton, Stein, etc. zu schaffen, der durch das bloße Einschlagen in das Dübelloch und ohne Nachspreizen bereits den gewünschten Halt erfährt und bei dem für die Lagerung der Spreizhülse keine Ausnehmung auf dem Bolzen vorgenommen werden muß.The Invention sets itself the task of a cheap expansion dowel for predominantly hard bodies like Concrete, stone, etc. to create, by mere whipping in the dowel hole and without Nachspreizen already experiences the desired stop and at for the storage of the expansion sleeve no recess on the bolt must be made.

Beschreibung:Description:

Auf dem Bolzen 1 sitzt eine Spreizhülse 2, die längs geschlitzt ist und mehrere Schlitze aufweisen kann, von denen sich mindestens einer vom lochseitigen Ende aus nicht bis zum kopfseitigen Ende der Hülse erstreckt, wogegen die Anderen durchgehend angeordnet sein können. Der Bolzen 1 weist einen angestauchten Stumpfkegel 3 mit einem anschließend zyllindrisch angeordneten Zapfen 4 am lochseitigen Ende und einen angestauchten Kopf 5 an der gegenüberliegenden Seite des Bolzens 1 auf. Anstatt des Kopfs 5 kann ein Zapfen mit einem Außen- oder Innengewinde oder ein Flachkopf mit Loch angeordnet sein. Die Spreizlappen 6 der Hülse 2 sind gemäß dem Winkel des Stumpfkegels 3 an dem sie anliegen, abgewinkelt. Zwischen der Hülse 2 und dem Kopf 5 kann eine Scheibe 7 unter Tuchfühlung mit der Hülse 2 und dem Kopf 5, angeordnet sein. Diese Scheibe 7 verfügt über einen Außendurchmesser, der größer ist, als der des Kopfs 5 und eine Bohrung, die größer ist, als der Durchmesser des Bolzens 1. Zudem weist sie einen Schlitz 8 auf, dessen Breite kleiner ist, als ihre Bohrung und kleiner ist, als der Durchmesser des Bolzens 1. Der Schlitz ist so ausgebildet, daß die Scheibe radial federnd über den Bolzen 1 geschoben werden kann und anschließend unverlierbar auf dem Bolzen 1 sitzt.On the bolt 1 sits an expansion sleeve 2 which is longitudinally slotted and may have a plurality of slots, at least one of which extends from the hole-side end not to the head end of the sleeve, whereas the others may be arranged continuously. The bolt 1 has an upset stump cone 3 with a subsequently zylindrisch arranged pin 4 at the hole-side end and an upset head 5 on the opposite side of the bolt 1 on. Instead of the head 5 a pin with an external or internal thread or a flat head with a hole can be arranged. The expansion lobes 6 the sleeve 2 are according to the angle of the truncated cone 3 on which they rest, angled. Between the sleeve 2 and the head 5 can a slice 7 under close contact with the sleeve 2 and the head 5 be arranged. This disc 7 has an outer diameter that is larger than that of the head 5 and a bore that is larger than the diameter of the bolt 1 , It also has a slot 8th on, whose width is smaller than their bore and smaller than the diameter of the bolt 1 , The slot is formed so that the disc is radially resilient over the bolt 1 can be pushed and then captive on the bolt 1 sitting.

Ähnliche Dübel weisen einen Flachkegel auf und dafür verwendete Scheiben haben einen Durchbruch passend zum Profil des Flachkegels derart, daß sie über den Flachkegel bis hin zum Kopf des Dübels geschoben werden können. Der Nachteil dieser Dübel besteht insbesondere darin, daß bei Belastung des Dübels, bedingt durch den Flachkegel, eine schnelle Deformierung des Flachkegels entsteht, was einen bedeutenden Verlust der Haltekraft mit sich bringt. Dieser Flachkegel ist aber erforderlich, weil sonst die Scheibe axial nicht aufgescho, ben werden kann, da sie nur mit geringem Spiel auf dem Bolzen sitzen muß. Eine Scheibe ist aber bei der Gestaltung des Dübels mit einem Kopf erforderlich, weil durch das Anstauchen des Kopfs auf den Schaft des Bolzens nur ein im Durchmesser begrenzter Kopf möglich ist, der für zu befestigende Teile zu klein ist.Similar Dowels point a flat cone on and for that used discs have a breakthrough matching the profile of the Flat cone such that they over the Flat cone can be pushed up to the head of the dowel. Of the Disadvantage of this dowel is in particular that at Load on the dowel, due to the flat cone, a rapid deformation of the flat cone resulting in a significant loss of holding power brings. But this flat cone is required because otherwise the Disc can not be opened axially, as it can only be opened with a small amount Game must sit on the bolt. A disc is required in the design of the anchor with a head, because by upsetting the head on the shaft of the bolt only a diameter limited head is possible, which is to be fastened Parts is too small.
