Embodiment 1

[0054] Below the lower veneer 4, a moisture-proof bottom layer 5 made of floor moisture-proof paper, shockproof, moisture-proof and sound-insulating cushion film, elastic material cushion, etc. can be provided, which can effectively isolate the direct contact between the bottom surface of the floor and the ground moisture, and can effectively prevent the floor Moisture deformation, decay and other situations occur, and the floor's moisture-proof, anti-corrosion, sound-absorbing and shock-proof effects are greatly improved. The sawn groove destroys the irregular fiber direction of the floor wood, so as to minimize the internal stress and deformation of the wooden floor. In order to make the floor more flat and obedient without warping, and to improve the moisture inside the floor due to dry climate or high temperature direct sunlight A large amount of loss will cause the separation of the wooden floor and the cracking of the floor surface. Through the vertical and horizontal saw...

Embodiment 2

[0056] The solid wood middle board is made of fir board with a length of 930mm, a width of 135mm, a thickness of 12mm, and a dried moisture content of less than 12%. The longitudinal groove and the second longitudinal groove, the first longitudinal groove and the second longitudinal groove are arranged in opposite directions, and then the first transverse groove and the second transverse groove are sawed respectively on the upper and lower surfaces of the solid wood middle board, The first longitudinal groove and the second longitudinal groove of the solid wood middle plate are arranged at intervals from each other, the groove distance from the (convex) side of the solid wood middle plate to the first groove is 20mm, and the first and second longitudinal grooves The groove spacing is 20mm, and the groove width of the first and second longitudinal grooves is 1mm. The groove depth of the first and second longitudinal grooves is 80% of the thickness of the solid wood middle plate;...

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...
