Abstract: Attachment members (28) are used for securing insulation panels (30) to structural components (31). Each attachment member (28) includes a nail (29) which is driven by a setting tool into the structural component. A connecting region (26a) on guide tube (25) of the setting tool generates a frictional force with a counter-connecting region of a hollow shaft (28b) in the attachment member when the nail (29 is driven. By means of the generated frictional force it is possible to check if the attachment member is properly connected after the setting tool drives the nail. The frictional force between the guide tube (25) and the inside surface of the hollow shaft is greater than the frictional force between the hollow shaft (28b) and the insulation panel (30).

Abstract: A stop (1) for supporting a side of concrete form work (12) includes a deformable section (2) in the form of a collapsible sleeve (2) with an abutment (8). The sleeve is formed monolithically with the stop. A nail (13) with a head (13a) secures the stop (1) to a concrete structure or component (11) and when the nail (13) is driven its head (13a) runs up against the abutment (8). If energy in excess of the amount needed to drive the nail (13) in is present, the nail head (13a) striking the abutment (8) axially collapses the sleeve and damage to the stop (1) is avoided.

Abstract: 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).
