<p>Column base consisting of a downwards tapering lower part (11) sinkable into the ground and a barrel-shaped upper part (5) in which the column is mounted, said upper (5) and lower (11) parts being separate components. The upper and lower parts are provided with curved thrust elements. Moreover, the curved thrust elements of the upper and lower parts are provided with holes placed at mutually corresponding locations, the hole in the upper thrust element being larger than the hole in the lower thrust element, said upper and lower parts being joined together by their thrust elements by means of a barlike threaded part going through the holes, onwhich at least one tightening element (9) provided with an internal thread corresponding to the thread of the treaded part can be screwed, permitting the required adjustement of inclination in a vertical plane and of rotation relative to the vertical axis.</p> |
