The present invention relates to a prefabricated plastic pallet, and more particularly, by dividing the pallet into several sections so that they can be assembled to each other, the investment cost can be greatly reduced and the size can be varied according to the assembly.

As is well known, pallets are used for transporting a specific item in a certain stacking unit, and a rectangular panel in which the item is placed is formed, and a fork of the forklift is inserted in the lower left, right and front and rear directions of the panel. As the respective inlet is formed to load the goods on the top of the panel, then the fork of the forklift truck can be inserted into one side of the inlet to lift and carry the panel.

Such pallets are usually manufactured using wood or plastic. Since pallets made of wood are relatively heavy, they are not easy to use during transportation and manufacturing, and each wood is connected to each other through fastening means such as nails. Because of the connection structure, the strength of the joints is lower than that of other parts, and the nails may stick out, causing damage to the product, and it is easy to be damaged by impact depending on the material characteristic of wood. In addition to restrictions on use in domestic and international trade, there are also problems in disposal after use.

In the case of plastic pallets, it is possible to mold them integrally, so there are no joints like wooden pallets.However, in order to integrally mold injection molding, the investment cost increases due to the investment cost depending on the size of the mold. It takes a lot, and is lighter than a wooden pallet, but its weight is also considerable, which makes it difficult to handle and dangerous.

The present invention has been proposed in view of such a point, and the pallet is divided into at least three zones, but by forming a fastening protrusion and a fastening groove corresponding to each other at the contacting portions of each zone so as to be fastened to each other to manufacture and easy to manufacture, It is to provide a prefabricated plastic pallet that takes up less space for installation and requires less installation cost.
