Abstract

Eine Demontagevorrichtung Hinterschnittanker besitzt ein hülsenförmiges Abstützteil (2), das an seinem einen, eine Abstützschulter (3) bildenden Ende einen axial abragenden Riegelfortsatz (4) aufweist, der mit Lastangriffsmitteln (5) ausgestattet ist. Die Lastangriffsmittel (5) sind mit korrespondierend ausgebildeten Lastangriffsmitteln am rückwärtigen Ende der Hülse des Dübels in eine zugbelastbare Wirkverbindung bringbar. Das Abstützteil (2) besitzt eine wenigstens bereichsweise mit einem Innengewinde versehene Durchgangsbohrung (6), die sich durch den Riegelfortsatz (4) erstreckt und zur Aufnahme einer mit einem Aussengewinde (8) versehenen Welle (7) dient, die durch Rotation relativ zum Abstützteil (2) axial verstellbar ist. Die Welle (7) besitzt zwei Längsenden (9, 10) mit identisch ausgebildeten Kupplungselementen (11) für ein Adapterstück (12), dessen einer Längsabschnitt (13) einen Aussendurchmesser (a) aufweist, der kleiner ist als der Innendurchmesser (i) der Durchgangsbohrung (6) des Abstützteils (2) und am freien Ende mit einem auf die Kupplungselemente (11) der Welle (7) abgestimmten Anschlussteil (14) ausgestattet ist. Das gegenüberliegende Längsende des Adapterstücks (12) ist als Einsteckende (15) für die Werkzeugaufnahme einer Handwerkzeugmaschine, insbesondere einer Drehbohrmaschine, ausgebildet.

Figure 00000001
A disassembly device for undercut anchors has a sleeve-shaped support part (2), which at its one end, which forms a support shoulder (3), has an axially protruding locking extension (4), which is equipped with load application means (5). The load application means (5) can be brought into a tensile load-bearing operative connection with correspondingly designed load application means at the rear end of the sleeve of the dowel. The support part (2) has a through hole (6), which is at least partially provided with an internal thread, which extends through the bolt extension (4) and serves to receive a shaft (7), which is provided with an external thread (8) and which rotates relative to the support part (2) is axially adjustable. The shaft (7) has two longitudinal ends (9, 10) with identical coupling elements (11) for an adapter piece (12), one longitudinal section (13) of which has an outer diameter (a) that is smaller than the inner diameter (i) of the Through hole (6) of the support part (2) and at the free end is equipped with a connection part (14) matched to the coupling elements (11) of the shaft (7). The opposite longitudinal end of the adapter piece (12) is designed as an insertion end (15) for the tool holder of a handheld power tool, in particular a rotary drill.
