PROBLEM TO BE SOLVED: To prevent the fall of stacked boxes easily and positively even in case of loading a large number of corrugated cardboard boxes by stacking by inserting sheets, provided with a plurality of spikes sticking into the corrugated cardboard boxes, interposingly between the upper and lower faces of the stacked corrugated cardboard boxes, over the adjacent corrugated cardboard boxes. SOLUTION: Two sheets made of plastic plates formed by molding so as to have conical spikes 3 on one side near four corners of a square, for instance, are integrated being bonded facing oppositely to form a load collapse preventing sheet 1. This sheet 1 is placed on the upper face (the lower face to four boxes in an upper stage) of the corner gathered position of four mutually adjacent corrugated cardboard boxes 10n in each stage of a corrugated cardboard box group formed by aligning four corrugated cardboard boxes 10n longitudinally and laterally without a clearance facing the same direction in one stage and stacking them in ten stages. With such sheets 1 (nine sheets in total) placed between the respective stages, the horizontal position relation of the mutually adjacent boxes of a stack-loaded box group is constrained. |
