Since the mating portion 56 of the side panel 50 and the overlapping portion 88 of the end panel 80 that are sandwiched between 8a and 8a overlap and are in close contact with each other, the steel box 3 passes through between the mating portion 56 and the overlapping portion 88.
It is possible to prevent water from submersing in 0, and the steel box 30
Can improve the waterproofness.

In addition, the high waterproofness of the steel box 30 is such that the side lower frame 46 of the side member 40 and the end lower frame 76 of the end member 70 are respectively the long frame 108 and the short frame of the bottom member 100. After being assembled to each of the side recesses 110, the end projecting frames 78 are fitted into the side recesses 48e, the contents are stored and the lid 34 is covered, and then the bolt holes provided near the upper ends of the side recessed frames 48 and the end projecting frames 78 respectively. Since it can be realized by a simple operation of screwing bolts into 48d, 84, in the conventional storage box (Fig. 6), the extending portion 20 is bent and then the side pillar 12 and the metal plate 16 are bolted. It is possible to reduce the time and effort required for the assembling work as compared with the case of joining by tightening or nailing.

In the steel box 30, as described above,
In the side member 40 and the end member 70, the side panel 50 and the end panel 80 having the bent groove 54 and the groove 86, respectively, are used, and these groove 54 and 86 are used for the support 18 of the conventional storage box. Works the same as. Therefore, since the grooves 54 and 86 have the function of increasing the strength of the side panel 50 and the end panel 80, it is possible to withstand a load such as when a plurality of steel boxes 30 are stacked.
The steel box 30 is functionally inferior to the conventional storage box.

In the steel box 30 having the grooves 54 and 86, the conventional support 18 is not required, so that the number of parts is reduced, the parts are easily assembled and managed, and the parts cost is reduced. Can be reduced. Furthermore, since the side panels 50 and 80 in which the grooves 54 and 86 are formed by bending can be easily produced by press working, compared to the case where the support 18 is produced and attached in the conventional storage box, the parts are manufactured and assembled. It is possible to reduce productivity and improve productivity.

In addition, the grooves 54 and 86 are provided on the side panel 50 and the end panel 8 by adjusting the feed amount of the press machine.
It is possible to change the position and the number of zeros formed,

Since the size and shape of the grooved grooves 54 and 86 formed in the end panel 80 can be changed to desired ones, it is easy to change the strength of the side member 40 and the end member 70 by these changes. For example, the formation interval of each of the grooves 54, 86 may be narrowed, the number of the grooves 54, 86 formed may be increased, or the grooves 54, 86 may be widened or deepened to form a side member. It is easy to increase the strength of 40 and the end member 70.

Further, in this embodiment, almost all the constituent members of the side member 40, the end member 70 and the bottom member 100, that is, the side upper frame 44, the side panel 50, the end lower frame 76, the leg frame 104, the long frame. Since 108 and the like are produced by cutting and bending the plate-shaped material, the yield can be improved as compared with the case where the hollow square bars are used for the side columns 12 and the columns 18 of the conventional storage box. Therefore, productivity can be improved.

In this embodiment, the case where the side member 40 and the end member 70 are assembled in the rectangular parallelepiped steel box 30 has been described, but instead, the side wall member for the storage box according to the present invention is assembled. It is also possible to apply the mechanism to, for example, assembling both ends of one rectangular thin material forming the side of the hollow cylindrical body to each other, and in that case, high waterproofness similar to that of this embodiment is realized. can do. In that case, the overlapping portion and the mating portion are respectively provided in the vicinity of both side edges of the one rectangular thin plate, the female frame member is attached to one of the both side edges, and the male frame member is attached to the other. Then, for example, the side wall member is curved and erected around the disc-shaped bottom plate, and the male part of the male frame member is housed in the female part of the female frame member on both sides thereof, and such a female part is formed. The overlapping portion and the mating portion are overlapped and brought into close contact between the portion and the male portion accommodated therein.

In the present embodiment, the male part and the female part according to the present invention are the side concave portion 48e of the side concave frame 48 and the end convex frame 7.
The end projection 78a of No. 8 is not limited to such a shape, but the end projections 78a are formed so as to be able to be housed in each other so that the overlapping portion and the mating portion can be brought into close contact with each other when stored. As long as it has any shape, it may have any shape. In this embodiment, the mating portion 56 is previously formed on the side recessed frame 48 before the side members 40 and the end members 70 are assembled.
The overlapping portion 88 is overlapped with the end convex piece 78a of the end convex frame 78, but the mating portion and the overlapping portion are preliminarily attached to the female frame member or the male frame member instead. Instead, the mating portion may be superposed on the inner side surface of the female frame member only when the one side edge and the other side edge of the side wall member are assembled. For example, in the present embodiment, the side concave frame 48 and the end convex frame 78 are separately and independently separated from the other members until the side member 40 and the end member 70 are assembled. ,
The side concave frames 48 may be attached to both sides of the side panel 50, and the end convex frames 78 may be attached to both sides of the end panel 80.

The cross-sectional shape of the groove does not have to be a substantially rectangular shape as in this embodiment, and may be, for example, a groove having a triangular or semi-circular cross section. Further, the groove may be formed from one side of the pair of opposing sides of the rectangular thin plate member to the other side, and the side panel 50 of the present embodiment.
It is not essential to be formed vertically on the upper side and the lower side like the end panel 80. For example, a plurality of groove grooves may be formed in parallel and obliquely from the upper side to the lower side of the rectangular thin plate material, or may extend from the midpoint of the upper side to both ends of the lower side. There may be a mode in which the two grooves and the lower side form a triangle, and the grooves 18 in those modes also support the support 18 of the conventional storage box.
Since it functions similarly to, the number of parts can be reduced and productivity can be improved as in the present embodiment.

In this embodiment, the mating portion 56 and the overlapping portion 8
Although the case where 8 overlaps with each of the base piece 48a and the end convex piece 78a has been described, further, for example, the side panel 50 and the end panel 80 of this embodiment are extended in the longitudinal direction, and Both sides reach the inner surface of the narrow piece 48c, and both sides of the end panel 80 have the wide end pieces 78c.
May extend to the outer surface of. By thus expanding the overlapping portion and the joining portion, respectively, the narrow piece 4
Since the portion in close contact between 8c and the wide end piece 78c expands, it is possible to further improve waterproofness.
