Abstract
Connection of two longitudinal sections (10, 22) that are at an angle to each other, each longitudinal section (10, 22) having two connecting sides (12) and two wall sides (14), where at least one connecting side (12) of each section (10, 22) exhibits a groove (24) that is undercut on both sides and on both sides of the undercut groove (24) an integral longitudinal flange (30). The first longitudinal section (10) exhibits a transversely cut section face, the end face (16) of the first longitudinal section (10) which is secured at an angle to a connecting side (12) of the second longitudinal section (22). The first longitudinal section (10) exhibits a recess (18) at its end (16) in which a connecting element (60), introduced into the groove-like recess (34) between the longitudinal flanges (30) in the second longitudinal section (22), engages--as a result of which the connecting element (60) forms a mechanical joint by virtue of fit with the end recess (10). A connecting mass (54) for sealing the joint or to achieve an exact fit mechanical joint may be provided between the connecting element (60) and the end recess (18) of the first longitudinal section (10) and/or between the connecting element (60) and the longitudinal flange (30) of the second longitudinal section (22). The connection is particularly suitable for assembly of frame-type structures of longitudinal sections (10, 22) for the superstructures of road and railway vehicles.
