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.
