Attachment element for fastening insulation board at substrate, has clutch elements connected with each other by rotation of insulating element relative to threaded element around longitudinal axis parallel to rotational axis

摘要

The element (1) has a sleeve-shaped holder shaft (2) and a screw element (6) extended along a longitudinal axis (L). The holder shaft is provided with an insulating material holder (3) and a screwing channel (5) for retaining the screw element. First clutch element is arranged at a threaded element (7). Second clutch element (13) is arranged at an insulating element (8). The clutch elements are torque-proof connected with each other by the rotation of the insulating element relative to the threaded element around the longitudinal axis parallel to a rotational axis (D).
