Abstract:
1. An anchoring device, comprising: an anchoring element suitable for being anchored in an object of construction material with the aid of mechanical vibrations, wherein: the anchoring device further comprising a tool with a proximal portion and broadening portion distal of the proximal portion, wherein: whereby the anchoring element is capable of being anchored in the object by mechanical vibrations coupled into the tool while the tool is moved relative to the anchoring element, and, by the effect of the broadening portion expanding the anchoring element, a radially-outer surface of the anchoring element is pressed against a wall of a bore of the object, whereby by the common impact of the vibrations and the expansion at least a part of the thermoplastic material of the anchoring element is liquefied and pressed into structures of the object to form, after re-solidification, a form-fit connection with the object.
