[0002] Solid wood flooring, a common decorative material for both home and industrial use, is increasingly being used in everyday life and production. Solid wood flooring offers the advantages of warmth, softness, and comfort. Primarily composed of solid wood and a surface covering, it provides a pleasant user experience when laid on the floor. To achieve the desired effect of solid wood flooring, minimize the use of adhesives in homes, and create a healthy and comfortable living environment, manufacturers are actively using solid wood. The more solid wood, the greater the comfort and the more comfortable it is to walk on. However, solid wood has the disadvantage of being easily deformed, so greater effort must be put into controlling this deformation and achieving a more stable structure, making the flooring more reliable and reliable. Wood flooring is widely used because it maintains its overall shape, even through the changing seasons of spring, summer, autumn, and winter, and in environments with heating systems such as floor heating.

[0003] In existing technology, wood flooring includes solid wood flooring, engineered wood flooring, and laminate flooring. Laminate flooring's core is made of pressed wood chips and adhesive, typically containing more adhesive than solid wood flooring. Therefore, solid wood flooring is often preferred in decorative applications. However, the core structure of solid wood flooring is often composed of essentially spliced ​​panels, which can deform over time and is less durable than laminate and engineered wood flooring. Designing solid wood flooring to resist deformation has become a challenge we must address and one of the challenges in promoting solid wood flooring. Summary of the Invention

[0005] In order to achieve the above-mentioned invention purpose, the technical solution provided by this utility model patent is as follows:

[0006] The utility model first provides a deformation-resistant solid wood core board structure, which includes a radially cut block combination and a side board. A side board is provided on each side of the radially cut block combination. The radially cut block combination includes at least four radially cut blocks spliced ​​together in pairs. A plurality of parallel sawn seams are opened on the radially cut block. The direction of the sawn seams is parallel to the growth direction of plant fibers. The direction of the plant fibers on the radially cut block is parallel to the upper and lower surfaces. The direction of the plant fibers on the side board is parallel to the upper and lower surfaces.

[0007] On each radially cut block, as a structural type, the sawing seams appear in pairs in opposite directions, and the relative sawing seams are equal in length so as to be connected by a blank space in the middle of the radially cut block.

The sawing seams on the same side are arranged in alternating lengths, and two blank strips are provided in the middle of the sawing block.

[0009] In the anti-deformation solid wood core board structure of the present invention, when the quarter-cut blocks are arranged in combination, the sawn seams are parallel to each other and perpendicular to the side boards, so that the fiber direction of the quarter-cut blocks is perpendicular to the fiber direction of the side boards.

[0014] The utility model also provides a wooden floor, which includes a surface board and a solid wood core board. The solid wood core board is located in the middle of the surface board. The solid wood core board is the above-mentioned anti-deformation solid wood core board structure. The solid wood core board structure includes a radially cut block combination and a side board. A side board is provided on each side of the radially cut block combination. The radially cut block combination includes at least four radially cut blocks spliced ​​together in pairs.

[0027] Below we further explain the present invention in detail with reference to the accompanying drawings and specific embodiments, which include a deformation-resistant solid wood core board structure and a wooden floor containing the solid wood core board, in order to provide a clearer understanding of its structural composition and application methods. However, this does not limit the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figure 1 The present embodiment provides a deformation-resistant solid wood core board structure, which includes a radially cut block combination and a side board 2. A side board 2 is provided on each side of the radially cut block combination. The radially cut block combination includes at least four radially cut blocks 1 spliced ​​together in pairs. A plurality of parallel sawn seams 3 are opened on the radially cut block 1. The direction of the sawn seams 3 is parallel to the growth direction of the plant fibers. The direction of the plant fibers on the radially cut block 1 is parallel to the upper and lower surfaces, and the direction of the plant fibers on the side board 2 is parallel to the upper and lower surfaces.

[0030] On each radially cut block, as a structural type, the sawing seams 3 appear in pairs in opposite directions, and the relative sawing seams 3 are equal in length so as to be connected by leaving a blank space in the middle of the radially cut block. Multiple groups of parallel sawing seams 3 are provided with a blank space in the middle of the sawing block.

[0031] On each radially cut block, as another structural type, the sawing seams 3 appear in pairs in opposite directions, and the relative sawing seams are of different lengths and are connected by a blank space in the middle of the radially cut block. The sawing seams 3 on the same side are arranged in alternating lengths, and two blank strips are provided in the middle of the sawing block.

[0032] When the quarter-sawn blocks are arranged in combination, the sawn seams 3 are parallel to each other and perpendicular to the side panels 2 , so that the fiber direction of the quarter-sawn block 1 is perpendicular to the fiber direction of the side panels 2 .

[0033] As another structural type, when the radially cut blocks are arranged in combination, some of the sawn seams 3 are parallel to each other and perpendicular to the side panels 2, and some of the sawn seams 3 are perpendicular to each other.

[0034] like Figure 1 and Figure 6 As shown, a clamping bar 4 is provided in the middle of the radially-sawn block assembly, oriented parallel to the side panels 2. The clamping bar 4 serves to separate two adjacent radially-sawn blocks 1, creating an inner sandwich structure between the radially-sawn blocks 1 and the clamping bar 4, which in turn forms an outer sandwich structure with the two side panels 2. This significantly enhances overall stability.

[0035] like Figure 6 As shown, to increase overall stability, end panels are provided at the ends of the solid wood core panels, with the fiber direction of the end panels perpendicular to the fiber direction of the side panels. The end panels can be on one side or on two opposite sides to form a more stable structure.

[0036] Below we combine actual production use to explain the production process and form presentation of solid wood core board:

[0037] The first step is to dry the logs and then cut them radially to form multiple blocks of wood of the same size. The growth direction of the plant fibers in the blocks is consistent with the length of the blocks, thus ensuring the stability of the wood.

[0038] The second step is to splice multiple wood pieces together side by side so that their fiber directions are parallel to each other, and apply adhesive to form a large board, such as Figure 2 As shown;

[0039] The third step, such as Figure 2 and Figure 3 As shown, a large board is sawn along the cross section to form a plurality of long strips, each of which comprises a plurality of spliced ​​wooden square columns, wherein the fiber growth direction of the wooden square columns is perpendicular to the direction of the long strips;

[0040] The fourth step is to process the sawing seams on each long strip relative to each other. The sawing seams are located on the end faces of the wooden square columns and are arranged along the plant growth fibers. When processing the sawing seams, the long and short seams are arranged alternately, and the long and short seams are kept on both sides to form a seamed strip with deformation absorption, such as Figure 3 As shown, the saw cuts in the figure can have multiple forms, only one of which is shown in the figure, and other arrangements are also possible;

[0041] The fifth step is to saw the strips of slits to form equal length boards 6. Each equal length board has the same length and has a sawing seam. The direction of the sawing seam is the same as the length direction. There are multiple sets of corresponding sawing seams and blank strips connected by blanks on the end surface, such as Figure 3 As shown;

[0042] Step 6: Figure 4 As shown, the sawn seams are omitted in the figure. The equal-length boards 6 with sawn seams are further combined. First, a side board 2 is placed at the bottom, and the equal-length boards 6 are stacked on the side boards 2 so that the equal-length boards are stacked perpendicular to the side boards. The sawn seams on the multiple arranged equal-length boards 6 are usually kept parallel so that the sawn seams are perpendicular to the side boards. In order to further increase stability, a plywood can be laid on the equal-length boards, and then another layer of equal-length boards can be laid. Finally, another side board is laid on top of the equal-length boards and connected and fixed by adhesive to form a stable intermediate structure.

[0043] Step 7: Lay the middle structure flat at 90 degrees to form a narrow plate structure with side plates. To stabilize the ends, you can also add end plates to form a more stable enclosure structure.

[0044] Step 8: Figure 5 and Figure 6 As shown, according to the specification requirements of the floor core board, the narrow board structure or the enclosed structure is layered and processed to form a core board structure with the required thickness. The core board structure has the following structural composition: the solid wood core board structure includes a radially cut block combination and a side board, and a side board is provided on each side of the radially cut block combination. The radially cut block combination includes at least four radially cut blocks spliced ​​together in pairs, and a plurality of parallel sawn seams are opened on the radially cut block. The direction of the sawn seams is parallel to the growth direction of the plant fibers, the direction of the plant fibers on the radially cut block is parallel to the upper and lower surfaces, and the direction of the plant fibers on the side boards is parallel to the upper and lower surfaces.

[0045] Example 2

[0046] The present embodiment provides a wooden floor, which includes a surface board and a solid wood core board. The solid wood core board is located in the middle of the surface board. The solid wood core board is the above-mentioned anti-deformation solid wood core board structure. The solid wood core board structure includes a radially cut block combination and a side board. A side board is provided on each side of the radially cut block combination. The radially cut block combination includes at least four radially cut blocks spliced ​​together in pairs. A plurality of parallel sawn seams are opened on the radially cut block. The direction of the sawn seams is parallel to the growth direction of the plant fibers. The direction of the plant fibers on the radially cut block is parallel to the upper and lower surfaces. The direction of the plant fibers on the side boards is parallel to the upper and lower surfaces.

[0047] Example 3

[0048] This embodiment provides another form of deformation-resistant solid wood core board structure, which includes a radially cut block combination, wherein the radially cut block combination includes at least four radially cut blocks spliced ​​together in pairs, with multiple parallel sawn seams on the radially cut blocks, the direction of the sawn seams being parallel to the growth direction of the plant fibers, and the direction of the plant fibers on the radially cut blocks being parallel to the upper and lower surfaces, that is, the purpose of deformation resistance can be achieved only by the combination of radially cut blocks. When used in the core board of the floor, stability can be achieved by clamping the panels on the upper and lower surfaces of the floor, and deformation absorption can be achieved by adding the forward sawn seams, so that the entire floor structure is stable and deformation-resistant. As for the sawn seams, the edges of the radially cut blocks can be processed with depressions, but their essence is still the existence of sawn seams, and their purpose is still to absorb the deformation of the radially cut edges.

[0049] Based on this embodiment, the sawing seams can also have multiple directions, as long as the growth direction of the plant fibers is ensured to be parallel to the upper and lower surfaces.

[0050] Undoubtedly, the above are only a few optimal implementation forms of the present invention and do not represent all implementation forms of the core board and floor of the present invention. In short, the scope of protection of the present invention also includes other structural changes and substitutions that are obvious to those skilled in the art.
