２とで閉断面Ｂを形成する。 In order to integrally connect the floor plate unit 3 and the side wall unit 4, which are formed separately as described above,
The lower end of the lower bent portion 12 is fixed to the lower end folded portion 8c of the reinforcing member 8, and the inner wall of the vertical wall 11 is fixed to the outer surface of the vertical portion 8b. .
2 forms a closed section B.

があつたが、本発明によれば、床板ユニツト３と
側壁ユニツト４とを別個に形成した後、それらを
単に結合すればよいので製作がきわめて簡単にな
るものである。 In the conventional packing boxes for this type of dump truck, the floor plate and side walls were integrally formed in advance, and each reinforcing girder was attached to the outside of them. The reinforcing girders must be joined together by directly abutting each other, and it is difficult to adjust their joining positions.In particular, in order to fix the reinforcing girders to the back of the floorboard, the entire shipping box must be turned over. However, according to the present invention, the floor plate unit 3 and the side wall unit 4 are formed separately and then simply joined together, making the production extremely easy. It is what it is.
また前記床板ユニツト３と側壁ユニツト４との
結合後には閉断面Ａ，Ｂが形成され、従来両ユニ
ツトを単に溶接結合していたものに比べて格段に
強固に一体化することができ、積荷負荷による側
壁の外方への倒れも防止できる。 In addition, closed cross sections A and B are formed after the floor plate unit 3 and side wall unit 4 are connected, making it possible to integrate them much more firmly than in the past where both units were simply connected by welding. It is also possible to prevent the side wall from collapsing outward.
