Abstract

A frame for a switch cabinet, having vertical profiled frame parts, a floor frame and a cover frame. The floor frame and the cover frame are configured as punched, bent parts made of a steel-sheet blank and have a horizontal floor facing the switch cabinet interior on which floor the vertical profiled frame parts are fixed. The floor has a reinforced edge which is bent away from the switch cabinet interior. To be able to assemble this type of frame simply and rapidly, four plug-in protuberances are fixed to the floor of the floor frame and the cover frame, which each have at least one threaded recess. The vertical profiled frame parts have plug-in recesses by which they are inserted onto the plug-in protuberances. The vertical profiled frame parts also have screw holes which are arranged such that they align with the threaded recesses of the plug-in protuberance and fixing screws are threaded into the screw holes and screwed into the threaded recesses.
