DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0022] FIG. 1 shows, by way of example and schematically, a large component of a rail vehicle in a sectional representation. A section through a large component 1 in the form of a side wall is represented in a highly abstracted manner, which component is manufactured in a differential construction. This large component 1 is constructed from paneling 4 and a frame of bows 2 and ribs 3, with the section shown extending in the vertical direction between two ribs 3. The bows 2 are formed as planar sheet metal parts and are butt-welded to the paneling 4 via a laser welded seam 6. The ribs 3, vertically oriented in the installation position, are also welded to the paneling 4 (welded seam not shown) and have such a contour that a molding located on the ribs 3 is formed for supporting a C-rail 5. This C-rail 5 is joined to the bows 2 via a laser welded seam 6. There is no direct joint between the bows 2 and the ribs 3. The lower edge of the C-rail 5 is joined to the ribs 3 at their molding for support via a short welded seam 7. Forces acting on the C-rail 5 are thus introduced directly into the ribs 3.

[0023] FIG. 2 shows, by way of example and schematically, is a large component of a rail vehicle in a view onto the carrying structure of bows and ribs. The abstracted example from FIG. 1 is represented in the view from inside onto the large component, with the bows 2 being hidden by the C-rail 5. The bows 2 do not touch the ribs 3 and are not welded to them either. The C-rail 5 is joined to the ribs 3 via a welded seam 7, however. The laser welding method enables exact positioning of such a welded seam with very little spatial extension.

[0024] FIG. 3 shows, by way of example and schematically, a large component of a rail vehicle in an oblique view. A section of a large component 1 of a rail vehicle is represented in an oblique view from inside, which component forms a side wall with two window apertures. The large component 1 comprises a carrying structure of bows 2 and ribs 3, with C-rails being arranged on the bows 2. The ribs 3 are placed more narrowly between the window gaps to reduce the warpage of the side wall. In the exemplary illustrated embodiment, three C-rails 5 are provided below the window apertures, and these can be used, for example, for fixing seats. The same principle that underlies the invention can also be used in a roof, for instance, for fixing cable runs or air-conditioning ducts, or in an end wall.

[0025] FIG. 4 shows, by way of example and schematically, a detail of the large component of a rail vehicle from FIG. 3. The supporting of the C-rail 5 on a rib 3 is represented, with exact support of the C-rail 5 being guaranteed by the shaping of the outer contour of the rib 3. In this way, a welded seam can exactly join to the rib 3.

[0026] Thus, while there have been shown, described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
