Description

Technical Field

[0001] The present invention relates to the technical field of environment-friendly solid wood composite floors, and in particular to an environment-friendly solid wood composite floor. Background Art

[0002] Existing solid wood composite boards are mostly three-layer composite structures. By combining different woods, they achieve solid wood boards with stable structures, which are naturally environmentally friendly:

[0003] Solid wood boards are made from natural wood. During the processing, not too much glue or chemical substances are added, basically maintaining the natural properties of the wood. Therefore, the content of harmful substances such as formaldehyde is low, the environmental protection performance is excellent, and it is friendly to human health and the indoor environment.

[0004] Excellent texture:

[0005] Beautiful texture: It has natural wood textures, which are natural, beautiful and unique. It can add a natural and warm atmosphere to the home environment and is suitable for various decoration styles, whether it is simple modern style or classical Chinese style.

[0006] Comfortable touch: Its surface texture is warm and moist, and it feels comfortable to touch, giving people a feeling of getting close to nature.

[0007] Good performance:

[0008] High strength: The structure is compact, with high compressive, bending and seismic resistance. It can bear a large weight and pressure and is durable.

[0009] Good stability: After reasonable drying and processing, the dry shrinkage and wet expansion rate of solid wood boards are relatively low, the dimensional stability is good, and it is not easy to deform or crack.

[0010] Good hygroscopicity and air permeability: It can automatically adjust according to the humidity change of the environment, absorb or release moisture, which helps to maintain the humidity balance of the indoor air and create a comfortable living environment.

[0011] Easy to process: Solid wood boards are easy to be processed such as cutting, punching, carving, etc. It can be customized according to the design requirements and actual use conditions to meet the personalized needs of different consumers.

[0012] However, existing environment-friendly glues still produce a certain amount of formaldehyde, and after cracking, it is difficult to remove the glue, so it cannot be recycled more efficiently.

[0013] This case is proposed to solve or improve the disadvantages or deficiencies of the existing technology. Summary of the Invention

[0014] The present invention is achieved by adopting the following technical solutions:

[0015] An environment-friendly solid wood composite floor includes a first-layer solid wood board, a second-layer solid wood board, and a third-layer solid wood board. The second-layer solid wood board includes several composite solid wood boards. A vertical fitting groove is provided at the bottom of the first-layer solid wood board. A flange insert is fixedly provided on the composite solid wood board. The flange insert and the vertical fitting groove are fitted and are in an interference fit connection after fitting.

[0016] A horizontal fitting groove is provided at the bottom of the composite solid wood board. A horizontal fitting rib is provided at the upper end of the third-layer solid wood board. The horizontal fitting rib and the horizontal fitting groove are in an interference fit after fitting.

[0017] In a preferred embodiment, the moisture content of the flange insert on the side of the fitting surface adjacent to the first-layer solid wood board and the composite solid wood board should be controlled at %-% before assembly. After assembly, the flange insert and the vertical fitting groove are in a clearance fit. Then, the flange insert is humidified through a pinhole fogging device so that its moisture content reaches at least % or more, making the fit between the flange insert and the vertical fitting groove an interference fit.

[0018] In a preferred embodiment, the adjacent spacing of the flange inserts is ten to fifteen times the thickness of the first-layer solid wood board.

[0019] In a preferred embodiment, the gap between two adjacent horizontal fitting ribs is more than one time and less than two times the width of the composite solid wood board.

[0020] In a preferred embodiment, the thickness of the second-layer solid wood board is less than the thickness of the third-layer solid wood board, and the thickness of the third-layer solid wood board is less than the thickness of the first-layer solid wood board.

[0021] In a preferred embodiment, a silicone film is sprayed and formed in the vertical fitting groove, effectively reducing the probability of subsequent abnormal noises.

[0022] In a preferred embodiment, a silicone film is sprayed and formed in the horizontal fitting groove, effectively reducing the probability of subsequent abnormal noises.

[0023] In a preferred embodiment, a gap is left between two adjacent independent composite solid wood boards.

[0024] The advantages and positive effects of the present invention are:

[0025] 1. Compared with the prior art, the solid wood composite floor of the present application adopts a unique assembly process. After drying, the assembly structure shrinks, and then water is used to improve the bite at the joints after assembly, effectively improving the consistency and stability of the wood.

[0026] 2. Press the three-layer boards together through mechanical pressing, and use a silicone cushion layer to prevent abnormal noises caused by wear between the boards. BRIEF DESCRIPTION OF THE DRAWINGS
