<p>The invention relates to a height-adjustable support for a base plate (8) comprising two elements (1, 2) which have complementary effective areas. According to the invention, the height of the support can be altered by changing the mutual relative position of the elements and the elements (1, 2) can be wedge-shaped. Each element has the same wedge angle and can be stepped on a wedge flank (3) thereof, whereby the wedge flanks of both elements are complementary to one another.</p> |
