Abstract: A combined frame for an electromechanical box has eight transversal beams, eight major connectors and four longitudinal columns. Each transversal beam has a body, two side covers and two fasteners. The side covers are securely mounted on the body and each has a fastening hole. The fasteners are respectively connected to the fastening holes of the side covers. Each major connector is connected to two adjacent transversal beams and has an internal surface, an external surface, a bottom, a top, an abutting wall, two through holes and a mounting hole. The longitudinal columns are connected to the major connectors between the transversal beams and each longitudinal column has a body, two minor connectors and two fixing elements. The minor connectors are respectively and securely mounted in the body and are respectively connected to the major connectors.
