Composite wood floor

Abstract

The invention discloses a solid wood composite floor with high rigidity, especially the solid wood composite floor with high longitudinal strength and strong deformability prevention, comprising core layer 1, two balance layers 2, surface layer 3 and bottom layer 4. Five layers of floor are arranged in cross according to wood fiber trend and rigidity on long and wide directions is ensured. The core layer 1 is the assembly of multiple rectangle wood strips with the entire or extending length and the same thickness in longitudinal direction. The rest are single plate. Because multiple rectangle wood strips with the entire or extending length and the same thickness are arranged in longitudinal direction, internal stress can be eliminated effectively so as to prevent deformation. Furthermore, static bending strength and elastic modulus of floor in length direction is ensured effectively. In addition, the comb structure 5 of core layer 1 can absorb transverse expansion and furthermore the stability of floor is strengthened.

Description

technical field [0001] The invention relates to a solid wood compound floor structure with strong anti-deformation ability, belonging to the technical field of solid wood compound floor. Background technique [0002] At present, solid wood flooring has been recognized by the majority of users due to its environmental protection and closeness to nature. However, in the absence of resources in our country, especially the lack of rare wood, it will inevitably lead to the rise of solid wood composite flooring, because the core layer of solid wood composite flooring can be Made of ordinary natural wood. The solid wood composite floor in the prior art can be divided into three-layer solid wood composite floor and multi-layer solid wood composite floor. The single block is arranged longitudinally, and the core layer is arranged horizontally, that is, the surface layer is made of high-quality broad-leaved wood planks inlaid with jigsaw panels; the core layer is composed of ordinary...

AI Technical Summary

Problems solved by technology

Since the core layer is arranged horizontally, the lateral strength of the floor is guaranteed. However, since the longitudinal structure only has two layers of veneers, the surface layer and the bottom layer, its longitudinal strength is not enough. In the case of no large-area support under the floor, it is easy to break under force
