Abstract
A building board made of OSB (oriented strand board) which can be laid on beams, which are spaced apart parallel to one another, in order to form a subfloor in a residential or commercial building and which has two mutually opposite longitudinal edges and two mutually opposite transverse edges running at right angles to the longitudinal edges. One longitudinal edge and one transverse edge in each case has a tongue and the opposite longitudinal edge and transverse edge has a groove corresponding to the tongue, via which a plurality of building boards can be connected to one another and locked in the vertical direction in relation to one another. The tongue and the groove on the longitudinal edge are designed such that two boards which are connected to one another at the longitudinal edges are also locked in a horizontal direction in relation to one another.
