Technical Field

[0001] The utility model relates to the technical field of insect-proof multi-layer plywood, in particular to an insect-proof multi-layer plywood. Background Art

[0002] Plywood is a board-like structure made by peeling wood segments into veneers or planing wood blocks into thin wood (veneers / board embryos), and gluing multiple layers of veneers together.

[0003] After searching, a Chinese patent with publication number CN213137115U discloses an insect-proof multi-layer plywood, which can reduce the oxidation rate of plywood and reduce the entry of external moisture, effectively ensuring the dryness inside the plywood and improving the overall insect-proof effect. The aluminum foil edge protector can effectively ensure the working strength of the side of the plywood while achieving a good isolation effect, maximally reducing the entry and gnawing of external insects, and can also reduce the fuzzing of the side, thereby increasing the service life of the plywood.

[0004] However, this device cannot reinforce the moth-proof board. In the process of installing the moth-proof board on the plywood, the traditional process is just to glue it to the plywood. Such a structure can easily cause the connection between the moth-proof board and the plywood to be disconnected during long-term use, resulting in a weakening of the moth-proofing effect.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
