Abstract (en)

[origin: DE19810039A1] Panels (1) are mounted on or via a bolt (2). A large pressure force (F1) is applied by a hydraulic unit (30) to clamp the panels together and a clamping nut (4) is screwed to bolt. Nut is turned in direction of and only enough force is applied to move the nut along bolt until it engages on stacked panels. Not counter/clamping forces are applied to the nut. A hollow body (31) is fitted over the nut to transmit hydraulic force to panels. Body supports itself via hydraulic unit on a coaxial counter bearing (20) and moved axially with the boot, when the force is switched off
