<p>The device (10) has a lower bearing area arranged on underground, and an upper bearing area (14), where a floor area of a scaffolding structure, scaffolding handle or a foot spindle is supported on the upper bearing area. The upper bearing area is variably and adjustably positionable at a surface inclination angle of the upper bearing area relative to the lower bearing area. Plate-like upper and lower bearing units (16, 18) are rotatable to each other around a central rotation axis (20). The adjustable inclination angle lies within range between 0 and 10 degrees. The upper bearing unit and/or the lower bearing unit are made of wood or metal.</p> |
