Benefits of technology

This new design improves the strength and durability of wooden flooring products while also making them more resistant against damage from impacts caused during use. It achieves this through adding multiple balancing groovings that help prevent cracks at different points along its length. Additionally, these designs allow for better control over how well the product works when installed without causing any issues like warping due to changes made after installation. Overall, they improve their overall performance and longevity.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durability and appearance quality of solid wooden composites (SLCs) without compromising their environmentally friendly properties such as prevention from decomposition or weather damage caused by rainwater during outdoor activities over time.

Embodiment 1

[0039] Referring to Fig. 1 to Fig. 5, Fig. 9, wherein, surface solid wood board 1 is hard wood such as oak, walnut, teak, merbau, balsam pigeonpea, jatoba, birch, maple, elm, southwest birch, Hard maple and other materials, the core board 2 is made of high-density board or particle board, and the back board 3 is made of soft wood such as pine or eucalyptus or poplar; the surface solid wood board 1 is pasted on the upper surface of the core board 2, The lower surface of the core board 2 is glued to the back board 3; a balance groove 4 is opened on the lower surface of the core board 2.

[0040] The balance grooves are arranged horizontally or vertically or horizontally and vertically.

[0041] In order to maintain the strength of the core board 2 and most effectively improve the performance of the core board 2 against moisture and tile change, the specification of the balance groove is: the length direction of the groove 4 and the length direction of the floor form an angle of ...

Embodiment 2

[0043] Referring to Fig. 2 and Fig. 9, on the basis of embodiment 1 in this embodiment, the core board 2 is a high-density material core board with a thickness of 6 mm, and the length direction of the balance groove 4 is 45 degrees to the length direction of the floor. Angle, width of groove 4 is 2 millimeters, the distance between grooves 4 is 20 millimeters, the bottom of groove 4 is arc shape, and groove 4 depth is 1.2 millimeters.

Embodiment 3

[0045] Referring to Fig. 3 and Fig. 9, on the basis of Embodiment 1, the core board 2 is a particleboard core board 2 with a thickness of 6 mm, and the length direction of the balance groove 4 is 60 degrees from the length direction of the floor. Angle, width of groove 4 is 2 millimeters, and the distance between grooves 4 is 20 millimeters, and the bottom of groove 4 is triangular shape, and groove 4 depth is 2 millimeters.

Abstract

The present invention relates to one kind of three-layer balanced composite wooden floor board and its making process, and relates to building decorating material. The three-layer balanced composite wooden floor board includes one surface wood layer, one core layer with balance notch in the lower surface, and one back layer adhered together. The making process of the three-layer balanced composite wooden floor board includes the following steps: making surface wood board, making core layer board, making back board, combination and pressing, splitting and balancing, and forming. Compared with available technology, the present invention has the advantages of less core board deformation, less cracking, high stability and raised production efficiency.
