<p>1. Damper for the absorption of tilting oscillations between foundation (16) and a plate (14) forming the foot part of an appliance, in particular a high-voltage switching device (2) to be set up in regions endangered by earthquakes, with the use of threaded bolts (18), which are anchored in the foundation and penetrate the plate, and of spring elements (38), which are provided for oscillation damping and for limitation of the bending moment in case of oscillations, wherein the spring elements are arranged between the upper side of the plate and upper counterbearings (28, 30), which are mounted at the threaded bolts and surround the threaded bolts concentrically, characterised thereby, that the plate (14) rests on the fixed lower counterbearings (22, 24) mounted at the threaded bolts (18) and that annular springs (38) are provided as spring elements, display a hysteresis adequate for damping and are biassed in such a manner that a force-locking connection between the plate (14) and the foundation exists on a given settable force being fallen below.</p> |
