Abstract

A method for folding a pallet support, which uses multiple recessed folding lines arranged respectively on top and bottom surfaces of a board to form area blocks, and uses the area blocks and folding steps to form the pallet support with a trapezoidal cross section and a large flat binding surface on a top surface, wherein the folding steps attach the area blocks to corresponding area blocks in coordination with adjacent recessed folding lines. The structure of the pallet support is light in weight and resistant to bending and flexing, improves the stress strength, and enhances an object bearing capability and practicability for transportation work.

Description

Stacking method of pallet support

Technical field

The invention relates to a folding method for a pallet support member, in particular to a structure which is lightweight and can effectively resist bending, flexing, low cost, easy assembly, and has the capability of increasing the strength and carrying weight. A trapezoidal section pallet support forming method. Background technique

The traditional packaging structure for transporting goods uses the styrofoam floor. However, the styrofoam structure is not easily decomposed in nature, and the combustion generates harmful gases, so the damage to the environment is quite serious. For this reason, the styrofoam Disabling has become a common policy in all countries of the world.

The current load-bearing structure uses a wooden or metal frame. This wooden or metal frame structure is stable and can carry extremely heavy objects, but it has a relatively high weight, which affects the transportation and transportation costs. The recycling of wooden or metal frames is difficult, and any disposal is still a major concern for environmental protection.

To this end, the adoption of a lightweight, recyclable pallet structure is a common trend in modern packaging structures, and has also led to the development of modular pallet structures. However, the existing combined pallet structure is composed of a single pallet support member, which often causes the strength of the bending and flexing resistance to be insufficient due to the structural factors of the pallet support itself, thereby leading to the bearing capacity. Insufficient, unable to effectively carry the problem of heavier objects.

The existing solution is nothing more than increasing the thickness of the sheet to increase the strength of the sheet or using a complicated structure. However, in order to increase the thickness of the sheet, it is necessary to bond a plurality of sheets, and then open a slot for bonding, so that it is bound to Increasing the complexity of the technology, increasing the weight of the pallet, increasing the cost of transportation, and the tools that affect transportation, ultimately cannot meet the goal of lightweight and recyclable pallets. Summary of the invention

The object of the present invention is to enable the pallet support formed into a trapezoidal section to effectively resist bending, flexing, and increase the strength of the force by means of a special folding manner, thereby achieving weight bearing to strengthen the object. The planting capacity and the practicality of the transportation work; the invention can eliminate the process of bonding and processing multiple sheets by a single plate setting, and can greatly increase the strength and lightness of the load without increasing the cost. Quantitative purpose. The technical means for achieving the above object of the invention is as follows: firstly, a plurality of groove fold lines are respectively formed on the upper and lower surfaces of the plate, so that the plate surface is divided into a plurality of blocks of equal width and unequal width; The block is folded along the adjacent groove fold line to the central surface of the plate to be bound to the corresponding block surface to respectively fold a first thickness; the two first thicknesses are along the same Adjacent groove folding lines are folded toward the center of the other side of the plate to be attached to the corresponding blocks to respectively fold a second thickness; the second thickness is along the adjacent groove fold line, Folding and affixing to the corresponding block surface in a central direction of the plate to fold a third thickness respectively; and folding the second thickness along the adjacent groove fold line to the central direction of the plate Having the two third thickness sides abut against the corresponding block faces; finally, simultaneously, the two third thicknesses and the blocks against which they are abutted are along the adjacent groove fold lines, toward the plate After folding in the center direction, the sides of the second thickness are made Adjacent to the block in the center of the sheet, and by bending the groove fold line adjacent to the central block, the two corresponding sides of the second thickness are attached to each other, that is, the section is formed A pallet support having a trapezoidal and top surface having a relatively large flat surface.
