Grooved solid wood middle plate and composite board with same

Abstract

The invention relates to a groove type solid wood medium plate and a composite plate with the same. Grooves which have inclination angle of 30-90 DEG with a surface and are cut by a saw are distributed on the upper surface and the lower surface of a solid wood medium plate; inside stress of material can be damaged according to the density, the rigidity and the deformability of medium plate materials with different purposes, inside stress of a wood material can be properly and effectively adjusted, and a space for adjusting the expansion or contraction of the wood material is remained during the wood material is wet or dry, so that the smoothness of the surface of the composite plate is better ensured, and the submission with a contact surface is greatly improved; meanwhile, a buffering function when the composite plate is pressed is provided, so that the composite plate has soft and elastic texture when being pressed. The solid wood medium plate provided by the invention can be matched with an upper veneer and a panel on the upper surface and a lower veneer and a veneer or dampproof bottom layer on the lower surface. Both surfaces of a solid wood medium plate with longitudinal wood grains are provided with veneers with cross grains, wood grain fibers can interact due to different constriction and expansion directions, thus, tile-shaped deformation generated on the surface of the composite plate can also be avoided even if the composite plate is affected with damp in seasons with high temperature and high humidity.

Description

Technical field: [0001] The invention relates to the technical field of solid wood composite boards, in particular to a grooved solid wood composite board which is anti-deformation and has a buffering effect. Background technique: [0002] Solid wood composite panels have been used in the field of interior decoration and furniture for a long time, especially in the field of wooden flooring. Based on the economy of material acquisition and use, the wooden floors currently used in the market are generally tongue-and-groove flooring. Among them, the solid wood multi-layer composite floor is gradually selected by consumers due to its low cost and small deformation. The growth direction of wood fibers and the hardness and density distribution of the wood body are uneven. When the dry humidity in the atmosphere changes greatly, the floor will expand due to moisture absorption, so that the assembled floor boards push each other, forming a depression in the middle of the floor surfa...

AI Technical Summary

Problems solved by technology

[0007] The problem to be solved by the present invention is to overcome some deficiencies in the prior art that the internal stress of the solid wood multi-layer composite board causes deformation of the composite board and poor cushioning effect when the surface of the composite board is pressed.
