PROBLEM TO BE SOLVED: To configure a unit enclosure frame body by combining four split frame plates together, and integrate the split frame plates and the unit enclosure frame body together.SOLUTION: Groove constituting parts 2 and 3 are formed along ridge lines formed on a bent part between plate parts 1a and 1b and longitudinal rib parts 1c and 1d, and a bent part between the plate parts 1a and 1b and lateral rib parts 1e and 1f, and 1g and 1h. The longitudinal ribs of a split frame plate 1 butt against each other, and the lateral rib parts of stacked unit enclosure frame bodies A butt against each other. Thus, the pair of groove constituting parts are combined together to constitute a weld groove 4. A metal welding material 5 is melted and infilled into the weld groove 4 to constitute a connection part 7. Each split frame plate 1 and the stacked unit enclosure frame bodies A are connected together by the connection part 7.SELECTED DRAWING: Figure 1 |
