The connection fittings 10 and 10 having a keyhole-shaped insertion portion 10a at the tip thereof are fixed to each other by rivets. On the other hand, the short side plates 3 and 3'are bent at both sides to form bent portions 11 and 11 which are joined to the long side plates 2 and 2 ', and the corners are also removed at the end and the lower end of the bent portion 11. The folding pieces 12 and 13 are provided, and the upper end 14 of the bending portion 11 is adapted to be fitted into the insertion portion 10a of the connecting metal fitting 10. In addition, folding pieces 15 are also provided at the lower ends of the short side plates 3, 3 '. Further, the bottom plate 4 has rising walls 16, 16 ... Connected to the respective side plates are formed by bending on four sides, and folding pieces 17, 17, 18, 18 are also provided at the upper end of each rising wall 16 and corners are formed. Reinforcing plates 19, 19 ... Are fixed to the portion by rivets. The long side plates 2 and 2 ', the short side plates 3 and 3', and the bottom plate 4 are connected to each other by joints 20a to 20c. These joints, when assembled as shown in FIG. 3, have a cover portion 21 having a width (about 20 mm) slightly larger than the width W of both folded pieces, and an 8 mm wide holding portion 22 folded inward from both ends of the cover portion 21. , 22 respectively. This joint has four joints 20a, 20a ··· that are approximately the same height as the side plates for joining the long side plate and the short side plate, and the length of the long side plate for joining the side plate and the bottom plate. Long joints 20b, 20b having a length including the width of the bent portions of the short side plates at both ends, and short joints 20c, 20c having the same length as the short side plate excluding the bent portions are used, respectively. ing.

To assemble the assembly box configured as described above, first, as shown in FIGS. 1 and 2, the short side plates 3 and 3 ′ are attached to the insertion portions 10 a and 10 a of the connection fittings 10 and 10 of the long side plates 2 and 2 ′. The upper ends 14, 14 of the bent portions 11, 11 are inserted respectively. Then, the long side plate and the short side plate are connected to each other at the upper end portion, and the folded pieces 8 at both ends of the long side plate are adjacent to the folded pieces 12 of the adjacent short side plates. Therefore, the joint 20a is slid from below at four positions of the adjacent folded-back pieces 8 and 12, and the holding portions 22 hold the joint 20a from both sides to connect the folded-back pieces 8 and 12 to each other. Next, when the connected side plates are placed on the bottom plate 4, the folded pieces 9 of the long side plate and the folded pieces 13, 13 of the bent portion 11 of the short side plate are aligned on a straight line as shown in FIG. Then, the two adjacent portions of the folded-back pieces 9, 13, 13 and the folded-back piece 17 of the rising wall 16 of the bottom plate are connected by long joints 20b, 20b. Finally, when the folded piece 15 of the short side plate and the folded piece 18 of the rising wall 16 of the bottom plate are connected to each other at two places by short joints 20c, 20c, the long side plates 2, 2 ', the short side plates 3, 3 are connected. ′ And the bottom plate 4 are firmly connected to each other to form an integral assembly box 1 as shown in FIG. On the contrary, in order to disassemble the assembly box, the side plate and the bottom plate can be easily separated only by sequentially pulling out the joints from 20c, contrary to the above.

In the assembly box of the above-mentioned embodiment, each part such as the side plate is manufactured individually and is a semi-finished product with only the assembly process left, so it is convenient for handling such as transportation, and at the site only simple assembly work is required. I'm done. In addition, the disassembled side plate does not take up space, so it is convenient to store it on its own, and even if it is damaged, only that part can be replaced, so the life of the box is extended and the durability is excellent. .

In the above embodiment, the assembly boxes are joined and disassembled at four positions between the side plates and four positions between the side plates and the bottom plate. However, the positions and the number are not limited to the above embodiments, and the side plates are not limited to these. The design can be changed arbitrarily depending on the use and material of the box, such as providing it at a corner between the two or disassembling only two locations. Also, the shapes of the joint and the folded piece are not limited to those in the above-described embodiment. For example, a curl-shaped folded piece may be joined by a joint having a circular cross section, or a short side may be used instead of the entire side of adjacent side plates as in the above-described embodiment. There is no problem even if they are partially connected with a small size or spot-shaped joint.
