[Industrial applications]

 The present invention relates to a side wall structure of a transportation box such as a van type vehicle or a marine container. More specifically, the main frame is made of aluminum-based members, the side wall skin member is made of thin aluminum-based flat plates, and the frame and flat plates are assembled by riveting. This is related to the improvement of the side wall structure of 5).

[Prior art]

 FIG. 5 is a side view of a van type vehicle in which the present invention is implemented. FIG. 6 is a cross-sectional view taken along the line CC of FIG. 5, showing a connecting structure between the upper frame member 1 and the upper edge of the outer plate 2, and a connecting structure between the lower frame member 3 and the lower edge of the outer plate 2. First, the structure of the upper frame member 1 and the upper edge of the outer plate 2 will be described. The upper edge of the outer plate 2 is overlapped with the inside of the downward vertical flange 1a of the upper frame member 1 and the rivet 4 is used to form the box body. Along the longitudinal direction, one or more threads (two threads in the figure) are fixed at a relatively small pitch. Further, the lower side frame member 3 and the lower edge of the outer plate 2 are connected to each other by stacking the lower edge portion of the outer plate 2 on the outer side of the upward vertical flange 3a of the lower side frame member 3 with the rivet 4 in the longitudinal direction of the box body. There are one or more strips (two strips in the figure) across the two, and they are fixed at a relatively small pitch. As described above, the joining of the relatively thick side frame members 1 and 3 and the thin outer plate 2 with the rivet 4 has a bad influence on the weak, that is, on the thin outer plate 2 side. That is, the distortion generated by the rivet 4's rivets was generated on the thin outer plate 2 side and appeared as undulations (unevenness) on the outer surface of the completed side wall after rivet staking, which significantly impaired the aesthetics of the box.

[Problems to be solved by devising]

 The present invention has been made in view of the above problems, and an object of the present invention is to provide a box body having a beautiful appearance by suppressing the waving phenomenon caused by riveting as much as possible.

[0004]

[Means for Solving the Problems]

 The upper edge of the outer plate 2 and the vertical flange 1a of the upper frame member 1 are overlapped and fixed to each other by the rivet 4, and the lower edge of the outer plate 2 and the vertical flange 3a of the lower frame member 3 are fixed. In the side wall structure of the transport box body in which the two are overlapped with each other and fixed by rivets 4, one or more outward protruding ridges 5 are provided on the vertical flange 1a of the upper side frame member 1 in the longitudinal direction thereof, and A ridge 6 which overlaps the back side groove of the ridge 5 is provided on the upper edge of the plate 2, and the ridge 5 and the ridge 6 are overlapped with each other. Above, the vertical flange 1a and the upper edge of the outer plate are fixed by rivets 4 in the longitudinal direction. Further, one or more ridges 5'are provided in the vertical flange 3a of the lower side frame member 3 in the longitudinal direction, and ridges 6'that overlap with the ridges 5'are provided near the lower edge of the outer plate 2. , The ridge 5'and the ridge 6'are overlapped, and the vertical flange 3a and the lower end edge of the outer plate 2 are rivets 4 in the longitudinal direction below the overlapping portion of the ridges 5'and 6 '. Stuck in. Furthermore, one or more ridges 5 are provided on the vertical flange 1a of the upper frame member 1 in the longitudinal direction, and a ridge 6 is formed near the upper edge of the outer plate 2 so as to overlap with the back side groove of the ridge 5. The ridge 5 and the ridge 6 are overlapped with each other, and the vertical flange 1a and the upper edge portion of the outer plate 2 are fixed to the upper portion of the ridge 5 with a rivet 4 in the longitudinal direction, and further, the lower portion. The vertical flange 3a of the side frame member 3 is provided with one or more ridges 5'in the longitudinal direction, and a ridge 6'which overlaps with the ridge 5'is provided near the lower end edge of the outer plate 2. The ridges 5 ′ and the ridges 6 ′ are overlapped with each other, and the vertical flange 3 a and the lower end edge of the outer plate 2 are fixed to each other with rivets 4 below the ridges 5.

[0005]

[Action]

 The ridges 5 or 5'provided on the frame material vertical flange 1a or 3a and the ridges 6 or 6'provided on the outer plate 2 are superposed on each other. Since the lower side frame material is fixed by riveting below the overlapping part, the overlapping part of the ridge serves as a boundary, and the irregularities that occur during riveting are outside the boundary part. No longer affected.

[0006]

【Example】

 A description will be given based on FIGS. 1 to 4. According to the present invention, in the upper frame member 1, the downward vertical flange 1a of the upper frame member 1 and the upper edge portion of the outer plate 2 are provided with the protrusions 5 and 6, respectively, and these are overlapped with each other. Fixed with rivets 4. In this way, by providing the ridges 5 and 6 on the edge portion on the side of the outer plate 2, even if riveting is performed on the upper portion, the strain does not affect the lower portion below the ridge portion, The waving phenomenon of the outer plate 2 is no longer visible. Also in the lower side frame member 3, in the same manner as above, one or more ridges 5'and 6'are provided on the lower side frame member 3 and the outer plate 2, and these are superposed and joined by the rivet 4. It has a structure. The rivet 4 is struck below the portion where the ridges 5'and 6'are overlapped.

In the illustrated embodiment, the upper and lower frame members 1 and 3 are provided with ridges 5, 6 or 5 ', 6'. As described above, basically, the ridges are basically provided on both the upper side frame member 1 and the lower side frame member 3, but unless the deterioration of the appearance due to the unevenness of either one is a problem, You can use it alone. Further, when the lower side frame member 3 and the lower edge of the outer plate 2 are joined together, the protrusion 6'of the outer plate 2 is made to overlap with the back side concave groove of the protrusion 5'of the lower side frame member 3. 1 (b), that is, the protrusion 5'of the lower frame member 3 is overlapped with the groove on the back side of the protrusion 6'of the outer plate 2 so that the vertical flange 3a is located below the overlapping portion. Of course, the lower end edge of the outer plate 2 may be fixed with the rivet 4 in the longitudinal direction.

[0008]

【effect】

 In the upper side frame member 1, it is above the protruding lines 5 and 6 which are superposed, and in the lower side frame member 3, it is below the protruding lines 5'and 6'which are also superposed. The vertical flange 1a or 3a and the outer plate 2 were riveted to fix them. As a result, the strain generated around the rivet 4 at the time of riveting driving becomes the boundary of the ridge, and the outer plate beyond the ridge is not affected, and the waviness phenomenon that impairs the appearance is eliminated. . As a result, the exterior appearance of the side wall structure of the transport box can be made more beautiful.
