[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail. FIGS. 1 to 4 show a pallet 1 according to an embodiment of the present invention and its constituent legs 10, a middle plate 20, and a rectangular top plate 30. FIG. The pallet 1 shown in FIG. 1 has, for example, three leg pieces 11 protruding at an interval on one side and three embedding recesses 13 provided on the other side opposite to the leg pieces 11, for example. Each leg 10 is made of reinforced corrugated cardboard (for example, three pieces) and has a planar shape as shown in FIG. 2. For example, three substantially rectangular planar shapes made of corrugated cardboard form a reinforcing plate that forms a flat portion together with the other side end face, and the middle plate portion 20 shown in FIG. A planar top plate 30 made of reinforced corrugated cardboard fixed to a flat portion formed by the plate portion 20 with an adhesive has a rectangular top plate 30 as shown in FIG. The three middle plate portions 20 and the rectangular top plate 30 have both ends 20a, 30a in a direction orthogonal to the leg portions 10 outside the respective leg portions 10, 10 located at both ends (both sides). It is structured to protrude. As shown in FIG. 9, as a material 50 of the reinforced corrugated cardboard forming the leg portion 10, the middle plate portion 20 or the top plate 30, a paper sandwiched between the front and back layers 51 and 52 made of paper as shown in FIG. The inner member 53 having a single corrugated layer (upper column in FIG. 9), the inner member 53 having two corrugated layers (the middle column in FIG. 9), and the inner member 53 having three corrugated layers. (Fig. 9, lower column) can be used. Next, a manufacturing process of the pallet 1 of the present embodiment will be described with reference to FIGS. First, a material 50 of reinforced cardboard is prepared and, though not shown, the material 50 is cut into a shape as shown in FIG. 2 which constitutes the pallet 1 by a cutter device or a press (cutting machine) controlled by a computer. This is used as a leg 10 and, for example, three legs 10 are prepared. The leg portion 10 has a shape in which, for example, three leg pieces 11 protrude at an interval on one side and three embedded recesses 13 are provided on the other side opposite to the leg piece 11. I have. Next, a reinforced cardboard material 50 is prepared, punched out with, for example, a cardboard press or an automatic cutting machine, and processed into a shape as shown in FIG. For example, three units 20 are prepared. The middle plate portion 20 has a fitting portion 21 into the recess 13 of the leg portion 10 and is formed in a flat shape as a whole. Further, a reinforced cardboard material 50 is prepared, punched out with a cardboard press, for example, and processed into a rectangular shape as shown in FIG. After preparing each leg portion 10, each middle plate portion 20 and the top plate 30 in this way, as shown in FIGS. 5 and 6, the three middle plate portions 20 are connected to the respective leg portions 10 and The fitting portions 21 are fitted into the respective recessed recesses 13 while fixing the respective joining surfaces using an adhesive, and the other side end surfaces of the three leg portions 10 are formed by the three middle plate portions 20. At the same time, a flat portion (flat surface) for fixing the top plate 30 is formed on the side opposite to the leg pieces 11. The pallet 1 shown in FIG. 1 is manufactured by fixing a rectangular top plate 30 made of reinforced corrugated cardboard to the flat portion formed by the legs 10 and the middle plate portions 20 using an adhesive. . The pallet 1 of the present embodiment having such a configuration uses reinforced corrugated cardboard as each of the legs 10, each of the middle plate portions 20 and the top plate 30, and has a combined structure of these. It has been confirmed that the strength is dramatically improved compared to conventional products against external forces from the direction, and that it can withstand a weight of about 20 tons. Also, the left and right ends 20a of the respective middle plate portions 20 orthogonal to the leg portions 10 are respectively exposed to the outside of the leg portions 10 and correspond to the left and right end 20a of the middle plate portion 20. Since the left and right ends 30a also protrude outward, a large loading area for luggage and the like on the top plate 30 can be obtained. The number and size of the legs 10 and the intermediate plates 20 can be freely changed according to the load-bearing design values. Furthermore, depending on the difference in the weight and type of the load, depending on the load capacity, the pallet 1 is composed of a single material 50 made of reinforced cardboard, and any number of sheets such as 2, 3, 4, etc. are stacked. Thus, the pallet 1 can be configured. Also, when one type of pallet is formed, it is needless to say that the pallet can be formed using a plurality of types of laminated materials 50. The type of paper cardboard used for manufacturing the pallet 1 can be either reinforced cardboard or normal cardboard. A plurality of the materials 50 are laminated and used on a portion of the pallet 1 where the claw 101 of the forklift 100 contacts, and a portion of the pallet 1 that does not require much strength is used as a material. A structure in which 50 is used alone may be adopted. Further, as shown in FIG. 8, a reinforcing plate 60 (indicated by a dotted line in FIG. 8) made of the material 50 is fixed to the protruding end face of each leg 2 of each leg 10 of the pallet 1 using an adhesive. An additional structure is also possible. The pallet 1 according to the present embodiment has the following effects. The manufacturing cost of the pallet 1 of the present embodiment is lower than that of a conventional wooden pallet made of synthetic resin. The pallet 1 of the present embodiment is lightweight and has excellent handleability. The pallet 1 of the present embodiment can be reused as long as it is not wet with water. If the pallet 1 of this embodiment becomes unusable due to damage or the like, it can be easily collected and recycled using the same means as ordinary cartons made of cardboard, and the resources can be reused to reduce environmental impact. Is good.

[Effect of the invention]

 According to the present invention described in detail above, the weight is light, the handleability is excellent, the pressure resistance as a pallet for heavy objects is sufficient, and it can be sufficiently used as a substitute for a wooden pallet or a resin pallet. Pallets that are easy to recycle, are environmentally friendly, and because the pallets themselves are lightweight, consequently contribute to reducing the load weight of luggage, etc., and contribute to reducing transportation costs. can do.
