Device preferably superficially situated hollow beams (11), e.g. sill beams, contained in a car body (10). The beams are in transverse direction stiffened by means of cross frames (14). The cross frame (14) is constituted by a tubular member (24) arranged transversely to the length axis, which at one end is provided with to this at least partially formed side flanges (30), which are firmly attached to the beam. The length of the tubular member (24) is at least slightly shorter than the distance between the opposite longitudinal sides forming a free space between the other end of the tubular member and one of the longitudinal sides of the beam. |
