At least one joint system having engagements is provided for thread-forming screws as fastening elements for particularly cost-effective manufacture of such type of constructional systems, and for simple assembly as well as for ensuring effective EMC screening in accordance with the invention between horizontally and vertically arranged components, in particular between side parts and a top part and a base part having multi-folded horizontal struts and/or vertical struts. Lug joints as second joint zones are preferably provided as an addition to the first joint system having joint zones accessible from the end faces and, third joint zones, for example, for sub-racks or equipment cabinets and which enable, for example, a fixing of printed circuit boards and the like by means of formed, threaded holes.
