PROBLEM TO BE SOLVED: To provide a housing of a switchboard which requires no skilled welding worker and requires only a small space for painting and is not bulky during transportation and storage. SOLUTION: A housing 14 of a switchboard consists of longitudinal beams 11, transverse beams 12, depth beams 13, and corner members. The corner member 18A is integrally formed from a vertical member with L-shaped cross section 15, a depth horizontal member with L-shaped cross section 16, a width horizontal member with L-shaped cross section 17. The corner member 18A and the other corner members are installed inside of each corner of the longitudinal beams 11, the transverse beams 12, and the depth beams 13 which constitute the housing 14 so as to prevent members for tightening the corner members and the beams from projecting outside. |
