<p>This invention relates to a framework for a switchboard cabinet, comprising at least twelve interlocking frame sections of an identical hollow rectangular structure, in which the hollow rectangular structure has rows of holes and forms an outer corner at the junction of two perpendicular side sections. Opposite the outer corner, the hollow rectangular structure has two side sections, each extending parallel to an opposite side forming the outer corner. The outer corners of all frame sections are aligned correspondingly and face the interior of the framework. Due to the special construction and arrangement of the frame sections, a framework is produced which is expandable with positive sealing on all sides, and in which interconnecting transverse struts, support rails, structural elements and the like, may be installed on all frame sections.</p> |
