Description

Technical Field

[0001] The utility model relates to the technical field of decoration boards, in particular to a new type of composite floor. Background Art

[0002] Solid wood boards are made from logs through processing such as cutting and grinding, and can be used as the basic materials for furniture such as cabinets or desks and chairs, or as floors and decorative boards. However, in reality, logs are difficult to obtain and thus expensive, and due to the characteristics of logs, under the influence of various environmental factors, a single log structure is extremely prone to moisture absorption and warping deformation. Therefore, boards composed of multiple layers of wood pressed and compounded are more widely used due to their firm and stable characteristics.

[0003] Composite boards for home decoration generally include three layers, namely the surface board exposed during installation, the core board below the surface board, and the bottom board located in the innermost layer. In order to save costs, the surface board usually uses oak boards with a higher density and harder texture, while the bottom board uses other boards with low costs, which also leads to a large difference in density between the surface board and the bottom board. As a result, there are significant differences in the shrinkage rate, expansion rate, stability, etc. between the surface board and the bottom board, directly affecting the quality of the composite board. In addition, the core board is usually composed of multiple small wood boards joined together. However, due to the gaps between the wood boards, affected by thermal expansion and contraction, it is very difficult to control the gaps between the small wood boards in the core board during summer or winter, thereby affecting the quality of the composite board. The most intuitive example is the composite board used as a floor, which will produce a creaking sound when stepped on in winter and summer, affecting the user experience.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a new technical solution. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of composite floor with higher stability, less affected by temperature, and better user experience.

[0006] To solve the above technical problems, the utility model provides a new type of composite floor, and the specific technical solution is as follows:

[0007] A new type of composite floor includes a surface board and a bottom board arranged up and down. A core board is fixedly connected between the surface board and the bottom board. The core board is formed by splicing and fixing multiple unit boards with the same thickness and the upper and lower surfaces respectively located in the same plane. Flaky cork stoppers are inserted between the core boards; the surface board and the bottom board are made of the same material.

[0008] Preferably, the upper and lower side surfaces of the core board are respectively fixedly glued to the surface board and the bottom board to form a glued layer.

[0009] Preferably, the cork stoppers and the unit boards are fixedly bonded through plant glue.

[0010] Preferably, the surface board, the bottom board and the core board are all square structures. Among the four sides of the core board, two adjacent sides protrude to form protruding parts with the side surfaces of the surface board and the bottom board, and the two sides of the core board opposite to the protruding parts are recessed with the side surfaces of the surface board and the floor to form recessed parts adapted to the protruding parts.

[0011] Preferably, the surface board and the bottom board are made of wooden boards of the same material, specifically oak boards.

[0012] Preferably, the thicknesses of the surface board and the bottom board are both not less than 3 mm, the thickness of the core board is not less than 9 mm, and the total thickness range of the novel composite floor is 15 - 19 mm.

[0013] Preferably, the core board is made of spruce or birch.

[0014] A novel composite floor of the present utility model has the following beneficial effects:

[0015] For the novel composite floor of the present utility model, by combining the surface board and the bottom board made of the same material, the upper and lower stresses during use of the composite board are controlled to be the same, which can ensure that the bottom and surface of the composite board have the same density, thereby ensuring that its elongation rate, expansion rate, etc. are consistent, having high overall stability, not easily generating defects such as bending and warping. At the same time, each unit board constituting the core board is filled with cork, ensuring that there will be no gaps caused by thermal expansion and contraction inside the composite board even under the condition of large temperature changes, thereby reducing the noise generated by the composite board under stress and providing a better user experience;

[0022] Embodiment

[0023] Please refer to Figures 1 to 2 , a new type of composite floor, including a surface board 1 and a bottom board 2 arranged up and down. A core board 3 is fixedly connected between the surface board and the bottom board. The core board is formed by splicing and fixing a plurality of unit boards 31 with the same thickness and the upper and lower surfaces respectively located in the same plane. A sheet-shaped cork 5 is inserted between the core boards; the surface board and the bottom board are made of the same material. The cork is a sheet-shaped board cut from cork similar to the cork of a wine bottle. The density of the cork is less than that of other wood species, and the density and hardness of the cork are moderate, the flexibility and elasticity are good, and it also has certain permeability and viscosity. It can effectively fill the gaps between the unit boards under the state of thermal expansion and contraction, improving the overall stability of the composite board. Especially when the composite board is used as a floor, it will not make a creaking sound like a conventional floor in winter and summer.

[0024] The upper and lower sides of the core board 3 are respectively glued and fixed to the surface board 1 and the bottom board 2 to form a glue layer 4. After applying the adhesive between the surface board, the core board and the bottom board, it is also necessary to press and shape them. Since this is a conventional technical means in the art, it will not be elaborated here.

[0025] The cork 5 and each unit board 31 are fixedly bonded by plant glue. After the cork and the unit board are bonded, it is also necessary to press and shape them. The specific shaping method is similar to the shaping methods of the above-mentioned surface board, core board and bottom board.

[0026] The surface board 1, the bottom board 2 and the core board 3 are all square structures. Among the four sides of the core board, two adjacent sides protrude to form a protruding part 32 with the side surfaces of the surface board and the bottom board, and the two sides of the core board opposite to the protruding part are recessed with the side surfaces of the surface board and the floor to form a recessed part 33 adapted to the protruding part. Each composite board has a protruding part and a recessed part, which is beneficial to the mutual clamping and fixing during installation after batch forming, greatly improving the installation convenience.

[0027] The surface board 1 and the bottom board 2 are made of wooden boards of the same material, specifically oak boards. Since oak boards have better performance and are most commonly used as surface boards in decorative building materials, oak boards are selected as the surface board and the bottom board in this embodiment. In actual use, other boards such as maple wood and eucalyptus wood can also be selected to achieve the purpose of the same stress on the surface and the bottom.

[0028] The thicknesses of the surface board 1 and the bottom board 2 are both not less than 3 mm, the thickness of the core board is not less than 9 mm, and the total thickness range of the novel composite floor is 15 - 19 mm.

[0029] The material of the core board 3 is spruce or birch.

[0030] The beneficial effects of the present utility model are as follows: By combining the surface board and the bottom board made of the same material, the upper and lower stresses during the use of the composite board are controlled to be the same, which can ensure that the bottom and surface of the composite board have the same density, thereby ensuring that its elongation rate, expansion rate, etc. are consistent, having high overall stability, and being not prone to generate defects such as bending and warping. At the same time, the use of cork stoppers to fill each unit board constituting the core board ensures that there will be no gaps caused by thermal expansion and contraction inside the composite board even under the condition of large temperature changes, thereby reducing the noise generated by the composite board under stress and providing a better user experience.

[0031] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, and variations to the above embodiments within the scope of the present utility model.
