An adjustable-height post (10) for construction formwork, which is preferably made of aluminum, consists of an outer tube (12) to which a threaded nut is fastened in a lossproof manner, and an inner tube (11) that has thread segments (13, 14) on the outer surface. The segments (13, 13', 13'', 13''') project into recesses (19, 19', 19'', 19''') of the outer tube (12). This embodiment produces a robust post (10) whose inner tube (11) is nonrotatably supported and guided in the outer tube (12). The inner tube (11) can more easily be manufactured with the threads (14) according to the invention; at the same time, material can be saved in the manufacture of the post (10).
