<p>PROBLEM TO BE SOLVED: To facilitate assembling and to simplify the whole structure by fit- fixing a step-wise partitioning member obtained by successively providing rear plates and bottoms plate into a surrounding member consisting of a U-shaped three-side plate and a connecting plate connecting its opening end part and fit-fixing small partitioning plates of the direction orthogonal to it. SOLUTION: A U-shaped three-side plate 10 is formed by fold-bending a rectangular plate. An insertion piece 9c is inserted and connected to gaps at the both end parts of a connecting plate 11 and the triangular piece of the plate 11 is fitted to a step part to rigidly connect the whole of them. The both ends of the plate 11 are connected to the free end of the plate 10 to constitute a surrounding member 12. The fitting grooves of a step-like partitioning member 18 consisting of rear plates and bottom plates are fitted to fitting grooves 8 provided at the double side plates B to stably install the rear plates and the bottom plates to the member 12. The member 18 successively provides the rear plates and the bottom plates following a splice plate and successively connects the splice plate of the plate 11. Then, the fitting grooves of a small partitioning plates 6 are fitted to fitting grooves to fix the plates 6.</p> |
