Anti-deformation solid wood core floor

Abstract

The invention relates to an anti-deformation solid wood core floor. The anti-deformation solid wood core floor comprises a veneer layer at the bottom, a surface layer of an upper surface layer, and a solid wood core material layer between the surface layer and the veneer layer, wherein balance layers are arranged between the surface layer and the solid wood core material layer, and between the veneer layer and the solid wood core material layer; a plurality of vertical anti-deformation saw cutting grooves are uniformly formed in the upper and lower surfaces of the solid wood core material layer along the transverse direction; the plurality of vertical anti-deformation saw cutting grooves in the upper surface of the solid wood core material layer and the plurality of vertical anti-deformation saw cutting grooves in the lower surface of the solid wood core material layer are mutually staggered; end part distances are reserved on the vertical anti-deformation saw cutting grooves in the upper and lower surfaces of the solid wood core material layer along the vertical two end parts of the solid wood core material layer. The anti-deformation solid wood core floor has the characteristics of high strength and strong anti-deformation capability; a phenomenon that a wood edge of a locking part is broken is unlikely to occur; the structure is stable and the locking is firm. A wood strip edge frame does not need to be additionally spliced and the industrial automatic production can be realized; the effect of solid wood floors is met and the anti-deformation solid wood core floor is suitable for mounting a heating floor and woods are saved; the yield is improved and the cost is reduced.

Description

technical field [0001] The invention relates to a deformation-resistant solid wood core floor. Background technique [0002] In the situation of shortage of high-grade solid wood resources, solid wood strips are used as the core material, and the veneer is glued up and down to make a three-layer solid wood floor. [0003] Three-layer solid wood floor (length 900--1880mm, width 122--220mm,) in the middle is the floor core material. In order to improve the anti-deformation ability of the core material, the long strip wood blocks (length 125-230mm, width 25-40mm, thickness 10-18mm) are usually arranged horizontally to make the core material by bonding, and the long wood blocks are arranged horizontally There is a 0.1-1mm gap between them, the purpose of which is to eliminate the deformation stress of the wood when it shrinks or expands, and the gap penetrates to both ends of the core. The surface layer (adhesive with higher-grade veneer and longitudinal grain veneer) and the ...
