Abstract: A supporting structure with two intersecting profile parts is provided. Both profile parts are each designed as a Z-profile with a web and two flanges bent out of a plane of the web along bending lines, and, at an intersecting point, have corresponding recesses for a plug-in connection of the profile parts. A first profile part has, in a lower flange, a substantially right-angled recess which is adjoined by a vertically running slot in the web. A second profile part has a recess which extends from the upper flange of the second profile part into the web and ends at a distance from the bending line between the web and the lower flange of the second profile part. The distance is matched to the vertical extent of the slot of the first profile part such that a sliding fit is formed between the first and the second profile part.

Abstract: The modules for the coach body are divided into module sections and individual pre-assembled sub-assemblies, whereby the modules are produced by joining the individual pre-assembled sub-assemblies to provide module sections and by subsequent joining of the module sections. The joining of the individual pre-assembled sub-assemblies to provide module sections or modules, the joining of the module sections to provide modules and the joining of modules to provide the complete coach body is carried out by cold joining with rapid connector elements (e.g. cold mountable connection elements) and/or specially produced connector components.
