Anchoring in a construction model

A method of anchoring an anchoring element in an object of construction material with the aid of mechanical vibrations, wherein the anchoring element comprises a coupling-in face suitable for transmission of mechanical vibrations, and which anchoring element further comprises a thermoplastic material, which forms at least a part of the surface of the anchoring element, the method comprising the steps of:

• positioning the anchoring element on the object in such a way that areas of the anchoring element comprising the thermoplastic material are in contact with the object;
• coupling a force and mechanical vibration via the coupling-in face into the positioned anchoring element, whereby the thermoplastic material is at least partly liquefied from a solid to a liquid state by the mechanical vibration where in contact with the object and pressed into the object to form a form-fit connection with the object after re-solidification,
• wherein the force and the mechanical vibrations are coupled into the anchoring element from a tool, into which the mechanical vibrations are coupled on a proximal side and which comprises a coupling-out face on a distal side, across which the mechanical vibrations are coupled into the anchoring element, and wherein either the force being coupled into the tool is a tensile force or a counter-element is provided for exerting a counterforce opposed to said force, wherein said counterforce is coupled as a tensile force into the counter-element.

A method for anchoring an anchoring element in an object with the aid of mechanical vibrations, which anchoring element comprises an axis and a thermoplastic material, which forms at least a part of the surface of the anchoring element, the method comprising the steps of:

• providing a bore in the object;
• positioning the anchoring element in the bore;
• providing a tool having a proximal portion and a distal end portion;
• positioning the tool in contact with to the anchoring element;
• coupling the mechanical vibrations into the tool and simultaneously moving the tool relative to the anchoring element in axial direction, a portion of the tool moving in an interior of the anchoring element, and thereby expanding the anchoring element and pressing the anchoring element at least locally against lateral walls of the bore and, due to the expansion and the effect of mechanical vibrations coupled into the anchoring element from the tool, liquefying the thermoplastic material at least partly, from a solid to a liquid state, where in contact with the wall of the bore to yield liquefied thermoplastic material, and pressing the thermoplastic material into the construction material in order to form a positive-fit connection with the wall after re-solidification.
