Description

High rigidity cardboard combined structure

The present invention is related to cargo loading, more specifically, it refers to a high-rigidity cardboard composite structure that can be used as a container, or its partition, top plate, and pallet.

A certain amount of goods can be loaded in containers for easy loading and storage. The conventional container is nailed with wooden boards, and the wooden box boards need to be disassembled one by one during unloading, so as to take out the containerized goods therein. Wooden containers use a large number of wooden thick plates, which are made of wood through sawing, planing, milling, and nailing. Therefore, they are heavy and have the problem of excessive logging that damages the green environment and ecology. However, in order to comply with the restrictions of various countries during international transportation operations, additional disinfection and deworming (egg) operations are required, which is quite troublesome. After arriving at the destination, in order to facilitate the removal of the containerized goods, the wooden container needs to be disassembled, and the wooden boards are often destroyed during disassembly, forming a large amount of waste that is difficult to handle, and the reuse rate is extremely high. Low.

In order to solve the above problems, the present invention proposes a high-rigidity cardboard composite structure, which can be assembled into containers instead of wooden boards, or used as partitions, roofs, or pallets in containers.

Technical features of the present invention: a high-rigidity cardboard composite structure, comprising: an inner frame, an outer frame, a first panel and a second panel; both the inner frame and the outer frame are made by folding a strip of cardboard A closed rectangular frame; the inner frame includes a first side plate and a second side plate folded at right angles to the outer edge of the first side plate; the outer frame includes a third side plate and a right angle folded to the of the third side A fourth side plate on the outer edge; the inner frame is combined inside the outer frame, and the fourth side plate is outside the second side plate and closely attached to each other; the third side plate is lined on the second side plate The bottom edge, the first side plate and the third side plate are parallel to each other; the first panel is fixed on the outer surface of the third side plate, and the second outer layer plate is fixed on the outer surface of the first side plate.

Preferably, several lined square tubes are arranged in parallel and extend through the inner frame and the outer frame.

Preferably, the lined square tube has a paper-made inner support component.

Purpose effect of the present invention:

In the present invention, the cardboard is folded into a rectangular frame, and then combined with the first panel and the second panel made of paper to form a full-edge and high-rigidity cardboard structure, which has good overall firmness and can be used as a container board or a partition inside a container. The pallet, the top plate, or the pallet that carries the goods at the bottom has good flexibility and versatility, and has good shock absorption, shock resistance, impact resistance and elastic deformation capacity, and can effectively disperse the external force evenly to achieve shock resistance and shock absorption. The purpose is to provide reliable protection for containerized goods.
