The invention relates to a system for laying and mechanically joining building panels, especially thin, hard, floating floors. Adjacent joint edges ( 3, 4 ) of two panels ( 1, 2 ) engage each other to provide a first mechanical connection locking the joint edges ( 3, 4 ) in a first direction (D 1 ) perpendicular to the principal plane of the panels. In each joint, there is further provided a strip ( 6 ) which is integrated with one joint edge ( 3 ) and which projects behind the other joint edge ( 4 ). The strip ( 6 ) has an upwardly protruding locking element ( 8 ) engaging in a locking groove ( 14 ) in the rear side ( 16 ) of the other joint edge ( 4 ) to form a second mechanical connection locking the panels ( 1, 2 ) in a second direction (D 2 ) parallel to the principal plane of the panels and at right angles to the joint. Both the first and the second mechanical connection allow mutual displacement of joined panels ( 1, 2 ) in the direction of the joint.
