Description

Technical Field

[0001] This utility model relates to the technical field of plywood, specifically to a high-toughness and high-strength plywood. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with their fiber directions perpendicular to each other.

[0003] Traditional plywood has a relatively simple structure, consisting of several boards glued together. Therefore, its functionality is also relatively limited. When used in specific environments, such as under long-term pressure, plywood is prone to deformation or even breakage due to its low toughness and frequent external pressure. This makes plywood unsuitable for use in specific environments and limits its application. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem this utility model aims to solve is that traditional plywood, due to its relatively simple structure consisting of several boards glued together, has limited functionality. When used in specific environments, such as under long-term pressure, the plywood's low toughness makes it prone to deformation or even breakage under frequent external pressure, rendering it unusable in those conditions and limiting its application.

The base layer B is disposed at the lower part of the base layer A, the connecting layer A is disposed at the upper part of the base layer A, the connecting layer B is disposed at the lower part of the base layer B, the pressure-bearing layer A is disposed at the upper part of the connecting layer A, the pressure-bearing layer B is disposed at the lower part of the connecting layer B, the high-toughness layer A is disposed at the upper part of the pressure-bearing layer A, and the high-toughness layer B is disposed at the lower part of the pressure-bearing layer B.

[0008] Furthermore, the connecting plate layer A also includes a triangular plate body one and a triangular plate body two, which are connected by splicing, and there are several triangular plate bodies one and two.

[0009] Furthermore, the pressure-bearing layer A also includes a top plate, a bottom plate, a toughening strip A, and a toughening strip B. The bottom plate is disposed below the top plate, the toughening strip A and the toughening strip B are disposed between the top plate and the bottom plate, and the toughening strip A is disposed above the toughening strip B.

[0010] Furthermore, the high-toughness layer A and the high-toughness layer B are made of ash wood.

[0011] Furthermore, the connecting plate layer A and the connecting plate layer B have the same specifications and structure.

[0012] Furthermore, the pressure-bearing layer A has the same specifications and structure as the pressure-bearing layer B.

[0013] Furthermore, the first and second triangular plates are made of ebony.

[0014] Furthermore, both the toughness strip A and the toughness strip B are made of ebony.

[0015] (III) Beneficial Effects

[0016] This invention provides a high-toughness, high-strength plywood with the following advantages: its novel structure makes the plywood more tough and stronger overall, enabling it to be used in specific environments, such as under long-term stress. Due to its higher toughness and strength, the plywood will not easily deform or break even under frequent stress, thus improving its service life and safety factor. Attached Figure Description
