    摘要： A device for joining material by anchoring an insert comprising a first material in a structure comprising a second material is provided. The first material is solid and comprises thermoplastic properties and the second material is solid and is penetrable by the first material when in a liquefied state. The device comprises a vibration device being configured to transmit vibrations to said insert to cause at least partial liquefaction thereof and being arranged to move, relative to said structure, along an insertion direction (ID) to insert said insert at least partly into said structure, a contact sensor being connected to the vibration device and being adapted to move together with the vibration device along the insertion direction (ID), the contact sensor having a sensor body being adapted to detect contact with said structure. A controller is further connected to the contact sensor and adapted for receiving a contact signal from the contact sensor indicating that the sensor body has come into contact with said structure.

    摘要： A method of anchoring a lightweight building element having a first building layer and an interlining layer distally of the first building layer, and possibly a second building layer distally of the interlining layer. For anchoring, the the distal end of a connector element is inserted into a mounting hole in the lightweight building element, and also a sleeve including a thermoplastic material is inserted into the mounting hole, the sleeve enclosing the connector element. Then, a distally facing liquefaction face of the sleeve is caused to be in contact with a proximally facing support face of the connector element. Energy impinges to liquefy at least a flow portion of the thermoplastic material of the sleeve, and the liquefaction face is pressed against the support face to cause at least a fraction of the flow portion to flow radially outward. After the flow portion has re-solidified, it anchors the connector element in the receiving object.

    摘要： A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.
