JP 2012-192938 A

  In the conventional box pallet as described above, among the side wall members formed by fusing the inner half and the outer half, the half on which the fitting convex portion is formed is formed thick, The half body in which the fitting convex part is not formed is formed thin.

  As described above, the half body on which the fitting convex portion is formed is formed to be thick, and the half body formed to be thick has a high rib height, so Due to the difference in wall thickness, deformation occurs. On the other hand, a thin half body has little such warpage deformation.

  When the side wall member is formed by welding the thick half body and the thin half body as described above, the thin half body with less warpage deformation is affected by the thick half body with large warpage deformation. However, there has been a problem that warp deformation remains in the side wall member.

  When the side wall member is deformed, there has been a problem in that the box pallet composed of the pallet member and the side wall member is hindered in the assembling work and the folding work.

  An object of the present invention is to solve the problems of the above-described conventional box pallet.

  In order to achieve the above-described object, the present invention includes a pallet member having a facing high bank portion and a facing low bank portion, a facing side wall member, and a facing other side wall member. In the box pallet, the side wall member is formed by welding two halves made of plate material divided into two perpendicular to the thickness direction, and the thickness of the central region of one half is The thickness of the central region of the other half is formed to be substantially the same.

  In a box pallet including a pallet member having an opposing high bank portion and an opposing low bank portion, one opposing side wall member, and the other opposing side wall member, the side wall member extends in the thickness direction. It is formed by welding two halves made of vertically divided plate materials, and the thickness of the central region of one half and the thickness of the central region of the other half Since the warp deformation of the two halves is prevented, the warp deformation of the side wall member formed by welding the two halves can be suppressed, Therefore, the assembling operation and the folding operation of the box pallet composed of the pallet member and the side wall member can be performed quickly and easily.

FIG. 1 is a perspective view of a box pallet according to the present invention. FIG. 2 is an exploded perspective view of a side wall member constituting the box pallet of the present invention.
