Composite board of solid wood or bark-peeled single baseboard with grooves

Abstract

The invention discloses a composite board of a solid wood or bark-peeled single baseboard with grooves. The solid wood or bark-peeled single baseboard of the composite board has longitudinal wood grains, a gluing surface of the solid wood or bark-peeled single baseboard is provided with a plurality of grooves, one side of a horizontal bark-peeled single board is glued to the gluing surface of the solid wood or bark-peeled single baseboard, and a longitudinal face plate is glued to the other side of the horizontal bark-peeled single board. By means of the grooves arranged on the gluing surface of the solid wood or bark-peeled single baseboard of the composite board, stress inside the wood can be moderately and effectively adjusted, adjusting space for wood expansion or retraction can be provided in moisture or dry environments, flatness of the surface of the composite board and stability of the board can be well guaranteed, and manufacturing costs and formaldehyde contents can be substantially reduced; and simultaneously, the horizontal bark-peeled single board is arranged on the upper surface of the solid wood or bark-peeled single baseboard, and retraction and expansion directions of wood grain fibers of the baseboard are different from those of the horizontal bark-peeled single board, the wood grain fibers are mutually restrained, and tile-shaped deformation can be prevented even if the composite board is affected with damp in hot and humid seasons.

Description

technical field [0001] The present invention relates to a composite plate of solid wood or veneer veneer bottom plate with grooves, especially refers to a kind of solid wood or veneer veneer bottom plate with grooves on the bonding surface, and affixed on the bonding surface. A horizontal veneer is provided, and a composite plate made of a longitudinal panel is pasted on the other side of the horizontal veneer. Background technique [0002] Solid wood composite panels have been used in the field of interior decoration and furniture for quite a long time, especially in the field of wood flooring. Based on the economy of material acquisition and use, the wood panels currently used in the market, in addition to traditional solid wood panels, Based on its low cost and small deformation, solid wood multi-layer composite boards are also widely used by consumers. The multi-layer composite board substrate, and then the vertical panel made of high-grade wood is pasted on the surface...
