BEFESTIGUNGSELEMENT ZUM BEFESTIGEN VON ISOLATIONSPLATTEN

摘要

A member (1) for securing insulation panels (7) to a structural component (8) is formed of an annular head (2) and an axially extending hollow shaft (3) extending from the head. The hollow shaft (3) is arranged to receive a nail (9) for fixing the member to the structural component (8). An axially extending section (4) is positioned within the hollow shaft (3) and has an abutment (5) at its end closer to the head (2). When the nail (9) is driven into the structural component (8) its head (2) contacts the abutment (5) and at least an axially extending part (4) of the section is collapsible to compensate for excess driving energy supplied to the nail whereby it is inserted for variable depths into the structural component (8). The collapsible part (4) of the section prevents compressive forces from exercising any damaging effect on the insulation panels (7).
