Abstract: A stud device for wall constructions, comprising a web (1) and at least one pair of flanges (2, 3, 4, 5) arranged at the longitudinal edges (6, 7) of the web (1) and protruding from the same side of the web (1) substantially parallelly to one another. In order to reduce the number of studs and the amount of work when erecting a right-angled corner, for instance, either facing inwardly or outwardly in the wall, the stud has an angle (&agr;) between the web (1) and the flanges (2, 4) at one of the longitudinal web edges (6) which, in such a right-angled corner, is 45°, and an angle (&bgr;) between the web (1) and the flanges (3, 5) at the opposite longitudinal web edge (7) which, in such a right-angled corner, is 135°.
