A kind of anti-deformation solid wood core floor

Abstract

The invention relates to an anti-deformation solid wood core floor, which comprises a veneer layer at the bottom, a surface layer on the upper surface, a solid wood core layer between the surface layer and the veneer layer, a solid wood core layer between the surface layer and the solid wood core layer, and a veneer layer and the solid wood layer. A balance layer is set between the core material layers, and the upper and lower surfaces of the solid wood core material layer are respectively distributed with multiple longitudinal anti-deformation sawing grooves along the horizontal direction, and the multiple longitudinal deformation-resistant sawing grooves on the upper surface of the solid wood core material layer are connected with the lower surface. Multiple longitudinal anti-deformation sawing grooves on the surface are staggered with each other, and the anti-deformation sawing grooves on the upper and lower surfaces of the solid wood core material layer respectively leave end distances along the longitudinal two ends of the solid wood core material layer. The invention has the characteristics of high strength and strong anti-deformation ability, is not easy to break the wooden edge of the locking part, has a stable structure, and the locking is firm. There is no need for additional bonding to make wooden strip frames, which can realize industrialized automatic production and meet the effect of solid wood flooring. It is suitable for floor heating installation, saves wood, increases production capacity, and reduces costs.

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 ...
