Description

High-toughness plywood

Technical Field

The utility model relates to a panel field especially relates to a high tenacity plywood.

Background

The plywood is a plate-shaped structure formed by rotationally cutting wood sections into veneers or cutting wood sections into thin wood (veneers/slabs) through a square plane and gluing multiple layers of veneers.

The plywood of the prior art is generally 3, 5, 9, 12, 15, 18mm and the like. The toughness and the compressive resistance of the plywood are improved through the structure of the tree species and the wood grain direction (grain direction), the toughness is strong when the plywood is thick, but the plywood is thick in size, heavy in quality and heavy in weight, so that the coating and decoration are limited or inconvenient.

Therefore, those skilled in the art should consider the development of plywood that is effective in achieving low weight and high toughness.

It can be seen that, the utility model discloses a high tenacity plywood is made by core, fibre web, metal mesh, and the line direction through board and net forms fan-shaped, forms the netted handing-over of horizontal direction by fan-shaped line direction, and rethread glue is sufficient in the impressed watermark of adjacent expanded metal and two cores, realizes fore-and-aft fixed, and the vertical and horizontal direction is gone up and is buckled each other like the chain to increase toughness. The metal mesh is used to the medium plate position of this plywood, uses the fibre web in the metal mesh both sides, can effectively increase toughness, can stably glue metal mesh and core simultaneously. Because this plywood only uses 5 layers of structures except panel and backplate, consequently can realize thin and the high characteristics of toughness, does benefit to and uses and promotes.
