Description

Technical Field

[0001] The utility model relates to the technical field of plywood, in particular to a high-strength pressure-resistant and deformation-resistant plywood. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them together with adhesive. It is usually made with an odd number of veneers, with the fibers of adjacent layers of veneers glued perpendicular to each other.

[0003] Most of the existing plywood is directly composed of multiple thin wood boards glued together. Due to the lack of effective constraints in this composition structure, the plywood is prone to deformation such as bending, warping, expansion or contraction when subjected to humidity, temperature changes and external forces, resulting in dimensional instability, affecting its performance and appearance. Therefore, it is necessary to provide a structure that can effectively constrain the internal structure of the plywood to improve the strength and deformation resistance of the plywood.
