ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a car bodies and, in particular to railway vehicle bodies.
2. Brief Description of the Prior Art
A similar car body of the prior art (DE 1900649 U1) consists of a body framework that has continuous top and bottom horizontal longitudinal beams, each of which is firmly connected to the other in the vicinity of the side walls, the roof and the floor structure by frames that run perpendicular to the four longitudinal beams. The individual open body framework fields that are formed between the frames and the longitudinal beams are thereby covered by means of partial side wall elements. The partial side wall elements that are adjacent to one another are tightly connected to one another along their outside edges. The partial side wall elements can be equipped on their insides with the conventional equipment for compartments, namely with fixed or folding seats.
The object of the invention, is to indicate measures that make possible a simple assembly operation and an efficient utilization of the space between the lateral frames of the car body framework.
SUMMARY OF THE INVENTION
When a car body is constructed as claimed by the invention, fully pre-assembled partial side wall elements, which can be provided as necessary with fixtures and equipment elements such as seats etc. and the finished interior wall covering can be inserted from outside into the respective open car body framework field. The respective partial side wall element thereby projects at least partly in particular into the area in the space between the frames, in which a thermal or acoustical insulation layer is inserted between the outside wall surface and the inside wall lining. The individual partial side wall elements are fastened to the vertical frames by means of an adhesive compound that at least in the area of the vertical side edges overlaps the entire length between the frame and the side edge when the parts are assembled. The partial side wall element is thereby stepped back in particular on its vertical side edges step-wise in the depth direction, so that its exposed outer edge areas have a segment that has a lower wall thickness than the segments between them in the longitudinal direction of the car body. As a result of this stepped configuration, the outer segment that has the lower wall thickness projects in front of the outer surface of the corresponding frame. Partial side wall elements that are adjacent to one another are therefore in contact with one another in a plane that is flush with their outer surfaces. The adhesive connection of the partial side wall elements to the corresponding frames is preferably accomplished by applying a continuous bead of adhesive to the outside of the corresponding frame, on which the inside of the related segment that has the lower wall thickness of the corresponding partial side wall element is placed. The respective segment that has the lower wall thickness thereby extends approximately to the center of the corresponding frame, so that between the adjacent partial side wall elements there remains a gap that is filled with jointing compound. A tight seal between the partial side wall elements is thereby achieved. In the depth direction, for example toward the center of the car body, it becomes possible as a result of the stepping of the respective partial side wall element not only to utilize the space between the frames, but to make the wall thickness large enough that the interior lining of the partial side wall element projects beyond the inside of the corresponding frame. The vertical frames are thereby protected by their location between neighboring partial side wall elements, whereby the neighboring partial side wall elements can be connected with one another by means of a lining that connects their interior surfaces and straddles the inside of the corresponding frame. The frames are thereby lined all around and do not present any hazardous surfaces either on the inside or the outside. The respective partial side wall element can be connected with the floor structure or with the corresponding bottom longitudinal beam by shaping a tongue on the lower horizontal inboard longitudinal edges of the partial side wall element in question, which tongue fits into a matching groove of a groove strip provided in the vicinity of the corresponding longitudinal beam, which groove strip is fixed in the space between the frames.
