Wood board

Abstract

The invention provides a wood board. The wood board comprises two surface layers and an inner layer clamped between the two surface layers, wherein the surface layers comprise a plurality of first wood bars; the inner layer comprises a plurality of second wood bars; annual rings of the first wood bars and the second wood bars are arranged in a staggered mode; and a straight line on which the first wood bars are located is perpendicular to a straight line on which the second wood bars are located. Compared with the prior art, the wood board has the beneficial effects that: the plurality of the wood bars are spliced to the form inner layer; the plurality of the wood bars and the wood bars of the inner layer are perpendicularly spliced to form surface layers; the inner layer is clamped between the two surface layers and is boned and formed, and the annular rings of the wood bars of the inner layer are arranged in the staggered mode; in a wood self-deformation stress process caused by temperature or humidity changes, stress between the wood bars is balanced out; and by virtue of this arrangement mode, the integral strength and the stability of the wood board are improved. On the other hand, the two surface layers and the inner layer are made of the same material, so that the integral deformation rate and the cracking rate of the wood board are greatly reduced.

Description

technical field [0001] The invention relates to the field of construction and home decoration, and in particular to a wooden board used as a wooden board and a cabinet body board. Background technique [0002] Door panels or wooden panels are commonplace in people's daily life and play the role of wind and anti-theft. On the other hand, wooden panels are also widely used on cabinets. With the improvement of social productivity and technological level, on the one hand, the technical level of wood boards has been improved, and on the other hand, the requirements for the strength and deformation resistance of wood boards have also been continuously improved. [0003] In the prior art, the boards made of solid wood are generally made of multi-layer solid wood splicing, such as the common three-layer solid wood boards in the prior art, including three layers of solid wood boards with different materials, and the three-layer solid wood boards are spliced ​​in the same direction ....

AI Technical Summary

Problems solved by technology

In actual use, on the one hand, the three-layer boards are spliced ​​in the same direction. When the wood itself is deformed due to temperature or humidity changes, the three-layer boards are prone to bending and folding, and the strength of the boards cannot be guaranteed. On the other hand, due to the different materials of the three-layer wood boards, different materials have different volume change curves and stress conditions when subjected to strong external forces, which affects the deformation rate of the wood boards to a greater extent. and crack rate
