Composite plate structure and box structure thereof

Abstract

Provided are a composite plate structure and a box structure thereof. The structural performance of a plate is improved through perforated holes and pits under the condition of greatly reducing the material and manufacturing cost, the bending strength of the plate is improved, and therefore existing corrugated paper and other plates can be replaced; the composite plate structure is applied to boxes and other structures, and the existing plates and box structures can be replaced under the condition of greatly reducing the material and manufacturing cost; and meanwhile the composite plate structure can be repeatedly utilized and greatly contributes to environmental protection benefits and related industries.

Description

technical field [0001] The invention relates to a board structure, in particular to a board that can greatly save material and achieve high bending and twisting strength. Background technique [0002] At present, most of the materials used in existing boxes and boxes are paper materials, roughly two types: corrugated cardboard and honeycomb cardboard. Corrugated paper is composed of at least three layers of paper. The upper and lower sides are flat paper, and the center is wavy. The three-layer structure provides enough strength to form a common box structure; however, because of its innate structural relationship, the wavy strip structure can only provide lateral resistance, and the straight direction The resistance to bending is rather weak, so it is easily damaged by external forces in this direction. [0003] The honeycomb cardboard roughly imitates the hexagonal structure of the honeycomb to replace the corrugated strip structure of the existing conventional corrugated...

Problems solved by technology

[0002] At present, most of the materials used in existing boxes and boxes are paper materials, roughly two types: corrugated cardboard and honeycomb cardboard. Corrugated paper is composed of at least three layers of paper. The upper and lower sides are flat paper, and the center is wavy. The three-layer structure provides enough strength to form a common box structure; however, because of its innate structural relationship, the wavy strip structure can only provide lateral resistance, and the straight direction Relatively weak resistance to bending and therefore vulnerable to damage from external forces in this direction

[0003] The honeycomb cardboard roughly imitates the hexagonal structure of the honeycomb to replace the corrugated strip structure of the existing conventional corrugated paper, and can provide resistance in all directions and greatly improve the structural strength of the overall box; Complicated, and the amount of materials used has not decreased, so the existing cardboard boxes on the market are still mostly made of corrugated paper

[0004] Furthermore, corrugated paper cannot be waterproof, and the box is also very weak against moisture (whether it is external moisture or moisture generated by internal storage items, etc.), so there will be differences in the storage environment or the transported items. limit

In recent years, the awareness of environmental protection has risen, because the manufacture of corrugated paper is quite energy-consuming and polluting, so the reuse of boxes has always been the goal of efforts from all walks of life; but due to the aforementioned restrictions, and the corrugated boxes are easily deformed by external force collisions, And after repeated use several times, its state and strength will be significantly reduced, thus reducing the chance of people to reuse
