Description

Technical Field

[0001] This utility model relates to the technical field of furniture materials, specifically to solid wood boards that are not easily deformed.

[0002] This utility model claims priority. The earlier application application number is 2024108864617, entitled "Solid Wood Board That Is Not Easily Deformed", with a priority date of July 3, 2024. Background Technology

[0003] Solid wood panels are solid wood materials formed by secondary processing of sawn solid wood. They are often made by splicing together several solid wood strips (narrow boards, short boards) using a certain splicing method. The main types are finger-jointed wood and engineered wood.

[0004] Finger-jointed wood: Solid wood strips (narrow boards, short boards) with parallel grain are glued together in length or width using finger-shaped glue to form a solid wood panel of a certain size.

[0005] Glueed timber: Solid wood strips (narrow boards, short boards) with parallel grain are glued together in length or width (some also require glued layers in thickness) to form boards and squares of a certain size and shape.

[0006] However, the existing solid wood panels (especially furniture doors such as wardrobe doors and cabinet doors) are not ideal in terms of strength and rigidity, and are prone to deformation due to changes in temperature and humidity.

[0007] Analysis of several wood cutting methods and the quality of the resulting boards: Cross-cutting refers to cutting along the main axis of the tree trunk. This method clearly reveals the concentric annual rings, radial rays, and color difference between heartwood and sapwood. The resulting boards are hard and wear-resistant, but easily broken, difficult to plan, and have a relatively low yield.

[0008] Tangential sawing refers to sawing along the main axis of the tree trunk, that is, along the grain of the wood, perpendicular to the radius of the trunk's cross-section. Tangential sawing has the advantages of being simple to operate and inexpensive because it minimizes waste and produces wider boards. Furthermore, tangential sawing can create beautiful wood grain patterns such as "large patterns" and "landscape patterns," making tangentially sawn solid wood boards commonly found on the market. However, tangential sawing also has some disadvantages, such as being prone to warping and having a higher rate of shrinkage and expansion. Its deformation rate is 1.5 to 2 times that of notching or radial sawing methods, easily leading to warping or twisting of the wood.

[0009] Radial cutting refers to the process of cutting a log into four parts and then sawing them. The portion obtained, furthest from the heartwood, is called radial-cut board. Radial-cut board typically exhibits straight grain and is stable. The angle between its cross-section and the growth rings is controlled between 30 and 60 degrees, a characteristic that gives radial-cut board its unique performance and appearance. A significant advantage of radial-cut board is its high stability, thanks to its straight grain. In terms of price, radial-cut board is relatively moderate, making it competitive in the market. However, it also has some drawbacks, such as longer processing time and relatively higher material consumption.

[0010] Slicing refers to the process of evenly cutting wood into four parts, and then finely sawing each part to obtain a board that closely resembles the heartwood. These boards are called sliced ​​boards. The angle between the growth rings and the board surface is usually controlled between 60 and 90 degrees, resulting in a smooth and straight grain that can even display an attractive tiger-stripe pattern.

[0011] The significant advantage of the engraving process lies in its excellent stability, exhibiting minimal deformation compared to other cutting methods. However, this delicate process also brings the problems of time consumption and material consumption; therefore, the price of engraving plates is the highest among the three cutting methods (tangential cutting, radial cutting, and serration).

[0012] When wood dries, its shape changes due to uneven shrinkage in different parts; this is called deformation.

[0013] The expansion and contraction of wood is mainly considered in three directions: longitudinal, radial, and tangential. The measurement unit is a percentage, commonly called the shrinkage rate. This value measures the volume change from a living tree to fully dried wood. This value also represents the maximum possible expansion and contraction of the wood, that is, the maximum change from the wettest (living tree / freshly cut) to the driest (fully dried) state. Of these three directions, the longitudinal change is the smallest, generally around 0.1% to 0.2%, so its impact on the overall wood shrinkage is very small and can be ignored. Relatively stable woods can have radial shrinkage of less than 2%, while some very unstable woods can reach 8%. However, these are extreme cases; most wood species have radial shrinkage between 3% and 5%. The tangential change is the largest of the three directions, with shrinkage variations ranging from 3% to 12%. Except for some extreme cases, most woods have shrinkage between 6% and 10%. The sum of the shrinkage and contraction in all three directions is the overall shrinkage rate of the wood.

[0014] Therefore, a type of solid wood board with better strength and rigidity that is less prone to deformation is urgently needed in the furniture industry (especially for solid wood boards used in furniture doors such as wardrobe doors and cabinet doors). Utility Model Content

[0015] The purpose of this utility model is to design solid wood panels that are not easily deformed. By adopting a small unit splicing mode, it overcomes the shortcomings of existing solid wood panels that are easily deformed, and is especially suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0016] This utility model is achieved through the following technical solution: a solid wood board that is not easily deformed, including a core board layer, the core board layer including multiple reinforcing structures arranged in parallel; adopting a small unit splicing mode to overcome the shortcomings of existing solid wood boards that are easily deformed, and is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0017] To further improve the non-deformable solid wood board of this utility model, the following configuration is adopted: the reinforcing structure includes two core strips and a reinforcing plate sandwiched between the two core strips; the reinforcing plate divides the entire core board layer into multiple small units, thereby changing the water absorption or dehydration area of ​​the core strips from a whole board unit to multiple small units, thereby reducing the possibility of deformation caused by water absorption or dehydration (i.e., moisture release) of the core board layer.

[0018] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the reinforcing plate is made of a material with greater strength than the core strip and less deformation than the core strip, such as high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, carbon fiber, high-strength environmentally friendly chemical board, etc.

[0019] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the core strip is obtained by longitudinal cutting of the board using a radial cutting plate or a slicing plate.

[0020] To further improve the non-deformable solid wood board of this utility model, the following arrangement is specifically adopted: a splicing unit is provided between two adjacent reinforcing structures, and the splicing unit may be composed of multiple wooden square units arranged in a straight line; the reinforcing structure with small deformation and high strength is used to restrain the deformation force of the splicing unit, thereby making the entire board non-deformable; a reinforcing plate is used to isolate the moisture crosstalk between each splicing unit, thereby avoiding deformation problems caused by moisture inside the board; two surface layers can also be glued together on the upper and lower surfaces of the splicing unit using hot pressing or cold pressing technology.

[0021] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: in the direction of the core strip length, the ratio between the core strip length and the length of each wood unit is 300~3600:20~200.

[0022] Preferably, the timber unit is a rectangle with a length-to-width-to-height (thickness) ratio of 20-200:20-200:10-30; more preferably, the ratio between the length, width, and height (thickness) of the timber unit can be 20:20:10, 50:60:15, or 200:200:30, etc., and is not limited thereto. The height of the timber unit is the same as the thickness of the core strip.

[0023] The ratio between the length, width (thickness) and height of the core strip is 300~3600:10~30:10~30; preferably, the ratio between the length, width (thickness) and height of the core strip is 2400:14:14 or 300:10:10 or 3600:30:28, etc., and is not limited to these.

[0024] The ratio of length to width (thickness) and height of the reinforcing plate is generally 300~3600:10~30:0.01~5; if carbon fiber is used, the ratio of length to width (thickness) and height of the reinforcing plate is generally 300~3600:10~30:0.03~0.4; if aluminum is used, the ratio of length to width (thickness) and height of the reinforcing plate is generally 300~3600:10~30:0.04~0.5.

[0025] The ratio between the length, width (thickness) and height of the edge skin is: 300~3600: 10~30: 0.15~5.

[0026] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the positional relationship between the pair of reinforcing structures and splicing units is: core strip - reinforcing plate - core strip - splicing unit - core strip - reinforcing plate - core strip.

[0027] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the wood unit is obtained by cutting the board using a double-cutting method with a radial cut board, a notched board, or a tangential cut board.

[0028] To further improve the non-deformable solid wood board of this utility model, the following configuration is adopted: the splicing unit is composed of multiple reinforcing structures arranged in a straight line. The reinforcing structure includes two core strips and a reinforcing plate sandwiched between the two core strips. The reinforcing plate is made of a material with greater strength than the core strips and less deformation than the core strips. The core strips are obtained by longitudinal cutting of the board using a radial cutting plate or a notched plate.

[0029] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the wood grain of the timber unit intersects the reinforcing structure at an angle of 80° to 90°.

[0030] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: a reinforcing plate is also provided on the periphery of the non-deformable solid wood board.

[0031] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: it also includes a panel layer disposed on both sides of the core board layer.

[0032] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: a reinforcing mesh is provided between the panel layer and the core layer.

[0033] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the reinforcing mesh and the reinforcing plate are arranged perpendicularly.

[0034] To further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the reinforcing mesh is made of a mesh material with a deformation amount less than that of the core strip and a strength greater than that of the core strip, such as glass fiber mesh, aluminum mesh, carbon fiber mesh, GRC reinforcing mesh, etc.

[0035] Compared with the prior art, this utility model has the following advantages and beneficial effects: Because this invention incorporates reinforcing plates between the core strips, which have greater strength and less deformation than the core strips, the entire reinforcing structure remains essentially undeformed under the tension of the reinforcing plates and optimized humidity control.

[0036] This invention incorporates a reinforcing plate within the core board layer, which prevents moisture from merging between the core strips on both sides of the reinforcing plate, thereby avoiding deformation of the entire board due to water absorption or decomposition.

[0037] This invention incorporates reinforcing plates between the core strips of the core board layer, which further increases the strength and rigidity of the core board layer and prevents deformation.

[0038] This utility model is constructed by splicing a reinforced structure with multiple wooden units. The reinforced structure, which has low deformation and high strength, is used to control the deformation force of the splicing units, thereby making the entire board less prone to deformation. Furthermore, compared to other utility models that use only reinforced structures, the cost of the board itself is reduced accordingly, which can meet the needs of customers at different price points.

[0039] This invention utilizes reinforcing plates to isolate moisture crosstalk between splicing units, thereby avoiding deformation caused by moisture within the board material.

[0040] This utility model is composed of a reinforced structure assembled horizontally and vertically, which can minimize the deformation of the board material.

[0041] This utility model adopts a cross-jointing (especially orthogonal jointing) design structure through a reinforced structure and splicing units composed of multiple timber units. The small unit design mode guides the deformation of the splicing units to the reinforced structure, thereby ensuring the optimal stability of the entire board.

[0042] In this invention, the core strip of the reinforcing structure is made of solid wood cut by longitudinal cutting of the board using a radial or serrated plate. The wood square unit is made of solid wood cut by double cutting of the board using a radial, serrated, or tangential plate. When splicing the wood square unit with the reinforcing structure, the grain of the wood square unit intersects the reinforcing structure at an angle of 80° to 90°, thereby minimizing the possibility of deformation of the overall board due to deformation of the wood square unit.

[0043] Due to the cutting method of the wood square units and the arrangement of them between the reinforcing structures (the wood square units are arranged with the grain of the wood intersecting the reinforcing structures at 80°~90°), the greatest possibility of deformation in this invention is deformation in the direction of the reinforcing structures. However, since the reinforcing structures are in a basically undeformed state, they restrain the deformation of the wood square units in the direction of the reinforcing structures, thereby making the entire board less prone to deformation.

[0044] This invention solves the deformation problem of existing solid wood panels by changing the water absorption and release unit of the solid wood panel from a whole panel structure to a multiple small unit structure that are spaced apart from each other, thereby enabling the entire solid wood panel to achieve the least possible deformation.

[0045] This invention incorporates a reinforcing mesh between the core board layer and the face board layer, which enhances the strength of the solid wood board in terms of thickness and prevents deformation of the board due to insufficient strength.

[0046] This invention can enhance the strength and rigidity of the core board layer itself, while also strengthening the strength and rigidity of the entire solid wood board, overcoming the shortcomings of existing solid wood boards that are prone to deformation. It is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors. Attached Figure Description

[0067] Definitions: Cross-cut board: refers to the board material obtained by cutting along the direction perpendicular to the main axis of the tree trunk.

[0068] Tangentially cut boards refer to boards produced by sawing along the main axis of the tree trunk, that is, along the grain of the wood, perpendicular to the radius of the trunk's cross-section.

[0069] Radial sawing involves cutting a log into four parts and then sawing them to obtain boards that are far from the heartwood.

[0080] Example 1: The solid wood board is not easily deformed, including a core layer, which consists of multiple reinforcing structures arranged side by side. It adopts a small unit splicing mode to overcome the shortcomings of existing solid wood boards that are prone to deformation, and is especially suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0081] As a preferred design option, this solid wood board, which is not easily deformed, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a core board layer, which is composed of multiple reinforcing structures 9 arranged in parallel. Adjacent reinforcing structures 9 are bonded together by an adhesive layer using hot or cold pressing technology.

[0082] Example 2: This embodiment is a further optimization based on the above embodiment. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: The reinforcing structure 9 includes two core strips 3 and a reinforcing plate 4 sandwiched between the two core strips 3; the reinforcing plate 4 is used to divide the entire core board layer into multiple small units, so that the water absorption or dehydration area of ​​the core strip 3 is changed from a whole board unit to multiple small units, thereby reducing the possibility of deformation caused by water absorption or dehydration of the core board layer.

[0083] As the preferred design solution, combined with Figure 1 , Figure 2 As shown, the reinforcing structure 9 includes two core strips 3 and a reinforcing plate 4 sandwiched between the two core strips 3. During installation, the core strips 3 and the reinforcing plate 4 are bonded together by hot pressing or cold pressing through an adhesive layer. The reinforcing plate 4 placed between the core strips 3 can increase the strength of the reinforcing structure composed of the core strips 3 alone and change the deformation of the reinforcing structure composed of the core strips 3 alone, thereby avoiding deformation.

[0084] Example 3: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: the reinforcing plate 4 is made of a material with greater strength than the core strip 3 and less deformation than the core strip 3, such as high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, carbon fiber, high-strength environmentally friendly chemical board, etc.

[0085] Combination Figure 1 , Figure 2As shown, as a preferred design, the reinforcing plate 4 is made of a material with greater strength than the core strip 3 and less deformation than the core strip 3, such as carbon fiber, aluminum alloy, high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, high-strength environmentally friendly chemical board, etc., so that the deformation of the entire reinforcing structure 9 is constrained by the reinforcing plate 4, thereby minimizing the deformation of the reinforcing structure 9.

[0086] Example 4: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 1 , Figure 2 As shown, to further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the core strip 3 is solid wood obtained by longitudinal cutting of the board using a radial-cut board or a slit-cut board. Since the radial-cut board or slit-cut board itself is the board with the smallest deformation among several types of boards, the wood obtained by longitudinal cutting will also have a smaller deformation possibility. Furthermore, due to the tensile force of the reinforcing board 4, the deformation of the entire structure becomes smaller, thereby achieving the purpose of being non-deformable.

[0087] Example 5: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: a splicing unit is provided between two adjacent reinforcing structures 9. The splicing unit may be composed of multiple wooden square units 8 arranged in a straight line.

[0088] As the preferred design solution, combined with Figure 1 , Figure 2 As shown, the non-deformable solid wood board includes at least two reinforcing structures 9, and a splicing unit composed of multiple wooden square units 8 arranged in a straight line is provided between the two reinforcing structures 9; an adhesive layer is provided between the reinforcing structures 9 and the splicing unit, and an adhesive layer is provided between the wooden square units 8.

[0089] In this process, the timber units 8 are glued together using hot or cold pressing techniques to form splicing units. The splicing units and the reinforcing structure 9 are also glued together using hot or cold pressing techniques. The splicing units are composed of multiple timber units and a reinforcing structure. The reinforcing structure, which has low deformation and high strength, is used to restrain the deformation force of the splicing units, thereby making the entire board less prone to deformation. Furthermore, the reinforcing board is used to isolate the moisture crosstalk between the splicing units, thereby avoiding deformation problems caused by moisture inside the board.

[0090] On the upper and lower surfaces of the splicing unit, two surface layers can be bonded together using hot or cold pressing techniques with an adhesive layer.

[0091] Example 6: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 1 , Figure 2 , Figure 3 As shown, to further improve the non-deformable solid wood board of this utility model, the following arrangement is specifically adopted: the wood unit 8 is a rectangle with a length-to-width-to-height (thickness) ratio of 20~200:20~200:10~30; more preferably, the ratio between the length, width, and height (thickness) of the wood unit can be 20:20:10, 50:60:15, or 200:200:30, etc., and is not limited to these. This facilitates the splicing of the wood units 8 and effectively ensures that the strength is not affected. The height of the wood unit is the same as the thickness of the core strip.

[0092] Typically, the length of the timber unit 8 can be 20mm, 40mm, 50mm, 60mm, 80mm, 100mm, 120mm, 150mm, 160mm, 180mm, or 200mm; the width of the timber unit can be 20mm, 40mm, 50mm, 60mm, 80mm, 100mm, 120mm, 150mm, 160mm, 180mm, or 200mm; and the height (thickness) of the timber unit 8 can be 30mm, 24mm, 20mm, 16mm, 14mm, 12mm, or 10mm.

[0093] Example 7: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: in the length direction of the core strip 3, the ratio between the length of the core strip 3 and the length of the wood unit 8 is 300~3600:20~200.

[0094] As the preferred design solution, combined with Figure 1 , Figure 2 , Figure 3 As shown, in the length direction of the core strip 3, the ratio between the length of the core strip 3 and the length of the wood unit 8 is 300~3600:20~200. Multiple wood units are glued together to form a splicing unit. Since the wood unit is a small unit structure, the deformation of a single (root or block) will be smaller, and the deformation of the splicing unit formed will also be smaller. Combined with the tensile force of the reinforcing structure, the possibility of deformation of the entire board is reduced.

[0095] In specific settings, the ratio between the length, width (thickness) and height of the core strip 3 is 300~3600:10~30:10~30; preferably, the ratio between the length, width (thickness) and height of the core strip 3 is 2400:14:14 or 300:10:10 or 3600:30:28, etc., and is not limited to these.

[0096] The ratio of length to width (thickness) and height of the reinforcing plate 4 is 300~3600: 10~30: 0.01~5; if carbon fiber is used, the ratio of length to width (thickness) and height of the reinforcing plate is generally 300~3600: 10~30: 0.03~0.4; if aluminum is used, the ratio of length to width (thickness) and height of the reinforcing plate is generally 300~3600: 10~30: 0.04~0.5.

[0102] Example 8: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: the positional relationship between the pair of reinforcing structures 9 and splicing units is: core strip 3-reinforcing plate 4-core strip 3-splicing unit-core strip 3-reinforcing plate 4-core strip 3.

[0103] As the preferred design solution, combined with Figure 1 , Figure 2 As shown, when the two reinforcing structures 9 and the splicing unit are arranged, their positional relationship is: core strip 3 - reinforcing plate 4 - core strip 3 - splicing unit - core strip 3 - reinforcing plate 4 - core strip 3. In the specific setup, an adhesive layer is also provided between the core strip 3 and the reinforcing plate 4, and between the core strip 3 and the splicing unit. Then, hot pressing or cold pressing technology is used to hot press or cold press them together to form the entire board.

[0104] Example 9: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: in the direction of the arrangement of the core strip 3 and the reinforcing plate 4 of the reinforcing structure 9, at least one edge skin 10 is provided that is in contact with the core strip 3 and has a strength ≤ the strength of the reinforcing plate 4, and the deformation of the edge skin 10 is ≤ the deformation of the reinforcing plate 4.

[0105] As the preferred design solution, combined with Figure 1 , Figure 2 , Figure 3As shown, in the direction of the arrangement of the core strip 3 and the reinforcing plate 4 in the reinforcing structure 9, at least one (or block) edge skin 10 is provided that is in contact with the core strip 3 and has a strength ≤ the strength of the reinforcing plate 4. The deformation of the edge skin 10 is ≤ the deformation of the reinforcing plate 4. In the specific arrangement, an adhesive layer is provided between the edge skin 10 and the core strip 3, and an adhesive layer is provided between the edge skin 10 and the reinforcing plate 4. They are then bonded together by hot pressing or cold pressing technology. Since the strength of both the edge skin 10 and the reinforcing plate 4 is better than that of the core strip 3, and their deformation is less than that of the core strip 3, the entire reinforcing structure 9 is less prone to deformation.

[0106] Example 10: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 1 , Figure 2 , Figure 3 As shown, in order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: the wood square unit 8 is obtained by cutting the board by a double cutting method using a radial cutting board, a notched cutting board, or a tangential cutting board.

[0107] In the reinforcing structure 9, the core strip 3 is made of board square (solid wood) cut by longitudinal cutting of the board using radial or serrated boards. The wood square unit 8 is made of board square (solid wood) cut by double cutting of the board using radial, serrated, or tangential boards. When splicing the wood square unit 8 with the reinforcing structure 9, the grain of the wood in the wood square unit 8 intersects the reinforcing structure 9 at an angle of 80° to 90°, thereby minimizing the possibility of deformation of the overall board due to deformation of the wood square unit.

[0108] Example 11: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 1 , Figure 2 , Figure 3 As shown, in order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: the splicing unit is composed of multiple reinforcing structures 9 arranged in a straight line. The reinforcing structure 9 includes two core strips 3 and a reinforcing plate 4 sandwiched between the two core strips 3. The reinforcing plate 4 is made of a material with greater strength than the core strips 3 and less deformation than the core strips 3. The core strips 3 are obtained by longitudinal cutting of the board using a radial cutting plate or a slicing plate.

[0109] As a preferred design, the splicing units can also be constructed using a reinforcing structure 9. This reinforcing structure 9 also employs a structure of two core strips 3 sandwiching a reinforcing plate 4. The reinforcing plate 4 is made of a material with greater strength and less deformation than the core strips 3. The core strips 3 are obtained by longitudinally cutting the board using radially cut or slotted boards. Compared to the solid wood panels constructed using timber unit 8, which are less prone to deformation, although the cost is higher, the strength is higher and the possibility of deformation is lower.

[0110] As a preferred design, the splicing unit can also adopt a combination structure in which the reinforcing structure 9 and the wooden unit 8 are arranged in a straight line: for example, 1 reinforcing structure is adjacent to 1 wooden unit 8, 1 reinforcing structure is adjacent to 2 wooden units 8, etc. When cutting, the reinforcing structure 9 and the wooden unit 8 in the splicing unit have the same size specifications.

[0111] Example 12: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: the wood grain of the wood square unit 8 intersects the reinforcing structure 9 at an angle of 80° to 90°.

[0112] As the preferred design solution, combined with Figure 1 , Figure 2 , Figure 3 As shown, the wood grain of the timber unit 8 intersects the reinforcing structure 9 at an angle of 80° to 90°, such as 80°, 82°, 85°, 88°, or 90°, so that the annual ring surface comes into contact with the reinforcing structure 9. This allows the deformation force of the timber unit 8 in the direction of the reinforcing structure to be restrained by the reinforcing structure, thereby achieving the goal of making the entire board less prone to deformation.

[0113] When the timber unit 8 is a cube or cuboid, it is generally assumed that the grain of the timber and the growth ring face are located on two intersecting planes of the cube or cuboid, and the grain of the timber and the growth ring face are almost perpendicular to each other. Thus, the standard setting of the grain of the timber unit 8 intersecting the reinforcing structure 9 at 80°~90° can be achieved in this paper.

[0114] Example 13: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 1 , Figure 2 , Figure 3 As shown, in order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: the periphery of the non-deformable solid wood board is also provided with a reinforcing plate 4.

[0115] As a preferred design option, a reinforcing board 4 is glued around the perimeter of the solid wood board that is not easily deformed using a hot-pressing or cold-pressing process.

[0116] Example 14: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Furthermore, to better realize the non-deformable solid wood board described in this utility model, such as… Figure 1 , Figure 2 , Figure 3 As shown, the following arrangement is specifically adopted: it also includes a panel layer disposed on both sides of the core board layer, and an adhesive layer is disposed between the panel layer and the core board layer.

[0117] As a preferred design option, to further enhance the strength and rigidity of the entire solid wood board, a veneer layer is glued to both sides of the core board layer using hot or cold pressing technology.

[0118] Example 15: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Furthermore, to better realize the non-deformable solid wood board described in this utility model, such as… Figure 1 , Figure 2 , Figure 3 As shown, the following arrangement is specifically adopted: a reinforcing mesh is provided between the panel layer and the core layer.

[0119] As a preferred design, to further enhance the strength and rigidity of the entire solid wood board, a reinforcing mesh is installed between the veneer layer and the core board layer; the veneer layer and the reinforcing mesh are bonded together with an adhesive layer, and the reinforcing mesh and the core board layer are bonded together with an adhesive layer. During processing and production, hot pressing or cold pressing processes can be used to further compact the veneer layer, reinforcing mesh, and core board layer.

[0120] This invention further fixes the core board layer by using reinforcing plates and reinforcing mesh, so that the core board layer is divided into small units from large units, thereby enhancing the stability of the solid wood board and preventing the solid wood board from deforming due to the absorption and release of moisture by the wood.

[0121] Example 16: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Furthermore, to better realize the non-deformable solid wood board described in this utility model, such as… Figure 1 , Figure 2 , Figure 3 As shown, the following arrangement is specifically adopted: the reinforcing mesh and the reinforcing plate are arranged perpendicularly.

[0122] As a preferred design, the positional relationship between the reinforcing mesh and the reinforcing plate 4 in the solid wood board is as follows: the multi-layer (block) reinforcing plates 4 are arranged in parallel within the space formed by the two reinforcing meshes, so that any layer (block) of reinforcing plate 4 forms an I-shaped structure with the two reinforcing meshes. In this way, the I-shaped structure can better increase the strength of the solid wood board and reduce the amount of deformation.

[0123] Example 17: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 1 , Figure 2 , Figure 3 As shown, to further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the reinforcing mesh is made of a mesh material with a deformation amount less than that of the core strip and a strength greater than that of the core strip, such as glass fiber mesh, aluminum mesh, carbon fiber mesh, GRC reinforcing mesh, etc.

[0124] As a preferred design, both reinforcing meshes are made of mesh materials with a deformation less than that of the core bar 3 and a strength greater than that of the core bar 3, such as glass fiber mesh, aluminum mesh, carbon fiber mesh, GRC reinforcing mesh, etc.

[0125] Preferably, when the entire solid wood board that is not easily deformed uses wood square units 8 as splicing units, the outermost periphery of the entire solid wood board that is not easily deformed is reinforced with a reinforcing structure 9.

[0126] Example 18: This solid wood board is designed to resist deformation. It adopts a small unit splicing mode to overcome the shortcomings of existing solid wood boards that are prone to deformation. It is especially suitable for furniture door panels such as wardrobe doors and cabinet doors. It includes a core board layer, which consists of multiple core strips arranged side by side and reinforcing plates sandwiched between the core strips. The reinforcing plates divide the entire core board layer into multiple small units, thereby changing the water absorption area of ​​the core strips from a whole board unit to multiple small units, thus reducing the possibility of deformation caused by water absorption or decomposition of the core board layer.

[0127] As the preferred design solution, combined with Figure 4 , Figure 5 As shown, the non-deformable solid wood board includes two panel layers, namely panel A1 and panel B6. A core board layer 7 is provided between panel A1 and panel B6. The core board layer 7 includes multiple core strips 3 arranged side by side. To increase the rigidity and strength of the core board layer 7, multiple reinforcing plates 4 (strips or blocks) are provided between the core strips 3. That is, one, two, three, or four strips can be separated into a small unit by a reinforcing plate 4 (strip or block).

[0128] During setup, in order to better bond the core strip 3 and reinforcing plate 4 within the core board layer 7, the core strip 3 and reinforcing plate 4 are bonded together with an adhesive layer. In further processing, hot pressing or cold pressing can be used to firmly bond the adhesive layer to the core strip 3 and reinforcing plate 4, making the entire core board layer 7 more compact.

[0129] To solve the deformation problem of existing solid wood panels, the water absorption and release units of the solid wood panels are changed from a whole board structure to a multiple small unit structure that is spaced apart from each other, so that the entire solid wood panel can achieve the least deformation.

[0130] A reinforcing plate is installed inside the core board layer to prevent moisture from merging between the core strips on both sides of the reinforcing plate, thereby avoiding deformation of the entire board due to water absorption or decomposition.

[0131] Setting reinforcing plates between the core strips in the core board layer can further increase the strength and rigidity of the core board layer and prevent deformation.

[0132] Example 19: This embodiment is a further optimization based on the above embodiment. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: a reinforcing plate is set between two adjacent core strips 3.

[0133] As the preferred design solution, combined with Figure 4 , Figure 5 As shown, a core strip 3 is separated by a reinforcing plate 4.

[0134] Example 20: This embodiment is a further optimization based on embodiment 18 or 19. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: the periphery of the non-deformable solid wood board is also provided with a reinforcing plate 4.

[0135] As the preferred design solution, combined with Figure 4 , Figure 5 As shown, a reinforcing board 4 is glued around the perimeter of the solid wood board that is not easily deformed using a hot or cold pressing process.

[0136] Example 21: This embodiment is a further optimization based on embodiment 18, 19 or 20. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: it also includes a panel layer respectively set on both sides of the core board layer 7, and an adhesive layer is set between the panel layer and the core board layer 7.

[0137] As a preferred design solution, such as Figure 4 , Figure 5 As shown, to further enhance the strength and rigidity of the entire solid wood board, a panel layer A1 and a panel layer B6 are glued to both sides of the core board layer 7 using hot or cold pressing technology.

[0138] Example 22: This embodiment is a further optimization based on embodiment 18, 19, 20 or 21. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: a reinforcing mesh is also provided between the panel layer and the core board layer 7; an adhesive layer is provided between the reinforcing mesh and the core board layer 7, and an adhesive layer is also provided between the reinforcing mesh and the panel layer.

[0139] As a preferred design solution, such as Figure 4 , Figure 5 As shown, to further enhance the strength and rigidity of the entire solid wood board, a reinforcing mesh A2 is provided between the panel A1 and the core board layer 7, and a reinforcing mesh B5 is provided between the core board layer 7 and the panel layer B6.

[0140] Panel A1 and reinforcing mesh A2 are bonded together with an adhesive layer; reinforcing mesh A2 and core board layer 7 are bonded together with an adhesive layer; core board layer 7 and reinforcing mesh B5 are bonded together with an adhesive layer; and reinforcing mesh B5 and panel B6 are bonded together with an adhesive layer. During processing and production, hot pressing or cold pressing processes can be used to further tighten panel A1, reinforcing mesh A2, core board layer 7, reinforcing mesh B5 and panel B6.

[0141] This invention further secures the core board layer by using reinforcing plates and reinforcing mesh, dividing the core board layer into smaller units, thereby enhancing the stability of the solid wood board and preventing deformation caused by the wood absorbing and releasing moisture. Long-term experiments have shown that solid wood boards with added reinforcing plates and mesh exhibit significantly improved resistance to deformation compared to those without, increasing by approximately 3.5 times under the same gravity.

[0142] Example 23: This embodiment is a further optimization based on embodiment 18, 19, 20, 21, or 22. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following arrangement is adopted: the reinforcing mesh and the reinforcing plate 4 are arranged perpendicularly.

[0143] As the preferred design solution, combined with Figure 4 , Figure 5As shown, the positional relationship of reinforcing mesh A2, reinforcing mesh B5 and reinforcing board 4 in solid wood board is as follows: multi-layer (block) reinforcing boards 4 are arranged in parallel within the space formed by reinforcing mesh A2 and reinforcing mesh B5, so that any layer (block) of reinforcing board 4 forms an I-shaped structure with reinforcing mesh A2 and reinforcing mesh B5. In this way, the I-shaped structure can better increase the strength of solid wood board and reduce the amount of deformation.

[0144] Example 24: This embodiment is a further optimization based on embodiments 18, 19, 20, 21, 22, or 23. The similarities with the aforementioned technical solutions will not be repeated here. Figure 4 , Figure 5 As shown, to further improve the non-deformable solid wood board of this utility model, the following arrangement is adopted: the core strip 3 is solid wood obtained by longitudinal cutting of the board using a radial-cut board or a slit-cut board. Since the radial-cut board or slit-cut board itself is the board with the smallest deformation among several types of boards, the wood obtained by longitudinal cutting will also have a smaller deformation possibility. Furthermore, due to the tensile force of the reinforcing board 4, the deformation of the entire structure becomes smaller, thereby achieving the purpose of being non-deformable.

[0145] Example 25: This embodiment is a further optimization based on embodiments 18, 19, 20, 21, 22, 23, or 24. The similarities with the aforementioned technical solutions will not be repeated here. Figure 4 , Figure 5 As shown, in order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: the reinforcing plate 4 is made of a material with greater strength than the core strip 3 and less deformation than the core strip 3, such as high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, high-strength environmentally friendly chemical board, etc.

[0146] As a preferred design, the reinforcing plate 4 is made of a material with greater strength than the core strip 3 and less deformation than the core strip 3, such as carbon fiber, aluminum alloy, high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, high-strength environmentally friendly chemical board, etc. This makes the deformation of a single small unit (core strip 3 + reinforcing plate 4 + core strip 3) constrained by the reinforcing plate 4, thereby minimizing the deformation of the small unit and further preventing the deformation of the entire board.

[0147] Example 26: This embodiment is a further optimization based on embodiments 18, 19, 20, 21, 22, 23, 24, or 25. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the non-deformable solid wood board of this utility model, the following setting method is adopted: the reinforcing mesh is made of a mesh material with a deformation amount less than that of the core strip 3 and a strength greater than that of the core strip 3, such as glass fiber mesh, aluminum mesh, carbon fiber mesh, GRC reinforcing mesh, etc.

[0148] As the preferred design solution, combined with Figure 4 , Figure 5 As shown, both reinforcing mesh A2 and reinforcing mesh B5 use mesh materials with less deformation and greater strength than solid wood, such as fiberglass mesh, aluminum mesh, carbon fiber mesh, and GRC reinforcing mesh.

[0149] Example 27: Solid wood panels that are not easily deformed, combined with Figure 4 , Figure 5 As shown, including the topmost (according to the appendix) Figure 4 , 5 The solid wood board consists of a panel A1, a reinforcing mesh A2, a core board layer 7, a reinforcing mesh B5, and a panel B6 at the bottom. The core board layer 7 is composed of multiple core strips 3 and reinforcing plates 4 sandwiched between the core strips 3. The positional relationship of the reinforcing mesh A2, reinforcing mesh B5, and reinforcing plates 4 in the solid wood board is as follows: multiple layers (blocks) of reinforcing plates 4 are arranged in parallel within the space formed by the reinforcing mesh A2 and reinforcing mesh B5, so that any layer (block) of reinforcing plate 4 forms an I-shaped structure with the reinforcing mesh A2 and reinforcing mesh B5. This I-shaped structure can better increase the strength of the solid wood board and reduce the amount of deformation.

[0150] Because of the reinforcement mesh A2 and reinforcement mesh B5 in terms of thickness, and the reinforcement plate 4 between the core strips 3 in the core board layer 7, the strength and rigidity of the entire solid wood board are greatly improved, thereby avoiding deformation.

[0151] like Figure 6 As shown, the non-deformable solid wood board of this utility model was placed outdoors and remained undeformed for 9 days in summer at a high temperature of 37 degrees Celsius.

[0152] like Figure 7 As shown, the non-deformable solid wood board of this utility model was subjected to alternating hot and cold temperatures, and the data on its thermal shrinkage were measured.

[0153] like Figure 8As shown, when the non-deformable solid wood board of this utility model was soaked in water for comparison with boards from competitors, it was obvious that the boards from competitors showed great deformation, while the boards of this utility model (indicated by the red arrow in the figure) showed no obvious deformation.

[0154] like Figure 9 As shown, the non-deformable solid wood board of this utility model was immersed in water for a water immersion test.

[0155] like Figure 10 As shown, ordinary boards show obvious signs of warping after prolonged exposure to sunlight.

[0156] like Figure 11 As shown, the actual state of the purchased brand solid wood board after 106 days outdoors is compared with that of the non-deformable solid wood board described in this utility model after 146 days outdoors.

[0157] like Figure 12 As shown, the non-deformable solid wood board of this utility model was placed in boiling water for a boiling test.

[0158] like Figure 13 As shown, the purchased solid wood boards are clearly deformed to the naked eye.

[0159] like Figure 14 As shown, the solid wood board that is not easily deformed described in this utility model is obviously very straight to the naked eye and there is no deformation.

[0160] Furthermore, during the research and development phase, corresponding comparative experiments were conducted on this utility model. Table 1 shows the results of high and low temperature cycle tests comparing the moisture absorption and desiccation warping (deformation) of the non-deformable solid wood board described in this utility model with that of ordinary boards on the market.
