Description

Technical Field

[0001] The present invention relates to the technical field of furniture materials, and in particular to a solid wood board that is not easily deformed.

[0002] This invention claims priority. The application number of the prior application is: 2024108864617, the name is: Non-deformable solid wood board, and the priority date is July 3, 2024. Background Art

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

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

[0005] Glued timber: Solid wood strips (narrow boards, short boards) with parallel water-texture are glued together to lengthen or widen them (some also need to be glued and layered in thickness) to form boards of certain specifications and shapes.

[0006] However, the strength and rigidity of existing solid wood panels (especially furniture door panels such as wardrobe doors and cabinet doors) are not very ideal, and there is a possibility of deformation caused by changes in temperature and humidity.

[0007] Analysis of several wood cutting methods and the advantages and disadvantages of the resulting boards: Crosscutting refers to cutting perpendicular to the main axis of the trunk. This method clearly reveals the concentric growth rings, radial rays, and the color difference between the heartwood and sapwood. The resulting lumber is hard and wear-resistant. However, it is prone to breaking, difficult to plan, and has a relatively low yield.

[0008] Tangential sawing refers to sawing along the main axis of the trunk, that is, along the wood grain, perpendicular to the radius of the trunk section. Tangential sawing offers the advantages of ease of operation and low cost, as it minimizes waste and produces wider boards. Tangential sawing also produces beautiful wood grains such as "large patterns" and "landscape patterns," which is why solid tangential sawn boards are commonly seen on the market. However, tangential sawing also has some disadvantages, such as easy deformation and a large shrinkage and expansion rate. The degree of deformation is 1.5 to 2 times that of scoring or quarter sawing, which can easily cause the wood to curl or twist.

[0009] Quarter-sawn lumber is a process in which a timber stump is cut into four sections and then sawn. The sections away from the heartwood are called quarter-sawn lumber. Quarter-sawn lumber typically exhibits straight grain characteristics and is stable. The angle between the cross-section and the annual rings is controlled between 30 and 60 degrees, making it unique in both performance and appearance. A significant advantage of quarter-sawn lumber is its high stability, which is due to its straight grain. Quarter-sawn lumber is also relatively affordable, making it competitive in the market. However, it also has some drawbacks, such as longer processing time and relatively high material consumption.

[0010] Slicing wood is a process where wood is evenly cut into four sections, each section then finely sawn to create a plank close to the heartwood. These planks are called slicing boards. The angle between the growth rings and the board surface is typically controlled between 60 and 90 degrees, resulting in a smooth, straight grain, sometimes even displaying a charming tiger-striped grain.

[0011] The significant advantage of the scoring process is its excellent stability, resulting in minimal deformation compared to other cutting methods. However, this delicate process also brings challenges in terms of time and material consumption. Therefore, the price of the scored board is also the highest among the three cutting methods (tangential cutting, radial cutting, and scoring).

[0012] After wood dries, its shape changes due to uneven shrinkage of different parts, which is called deformation.

[0013] Wood expansion and contraction are primarily considered in three directions: longitudinal, radial, and tangential. These are measured in percentages, often called shrinkage, and represent the volume change from a living tree to a completely dry piece. This value also represents the wood's maximum possible expansion and contraction, that is, the maximum change from its wettest state (live / freshly cut) to its driest state (completely dried). Of the three directions, longitudinal expansion is the smallest, typically ranging from 0.1% to 0.2%, making its contribution to the overall shrinkage of the wood negligible, effectively being ignored. Relatively stable wood can experience radial expansion and contraction of less than 2%, while some very unstable woods can experience changes of up to 8%. However, these are extremes; most wood species experience radial expansion and contraction between 3% and 5%. Tangential expansion is the most variable of the three directions, ranging from 3% to 12%. With some extreme exceptions, most wood species fall between 6% and 10%. The sum of the expansion and contraction in all three directions yields the overall expansion and contraction rate.

[0014] For this reason, a solid wood board with better strength and rigidity and not easy to deform is urgently needed by the furniture industry (especially solid wood boards for furniture door panels such as wardrobe doors and cabinet doors in the furniture industry). Summary of the Invention

[0015] The purpose of the present invention is to design a solid wood board that is not easy to deform, adopt a small unit splicing mode, overcome the shortcomings of existing solid wood boards that are easy to deform, and is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0016] The present invention is achieved through the following technical solutions: a solid wood board that is not easy to deform includes a core board layer, and the core board layer includes multiple reinforcing structures arranged side by side; a small unit splicing mode is adopted to overcome the shortcomings of existing solid wood boards that are easy to deform, and is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0017] In order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the reinforcement structure includes two core strips and a reinforcement plate sandwiched between the two core strips; the reinforcement plate 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 is changed from a whole board unit to multiple small units, thereby reducing the possibility of deformation caused by water absorption or dehydration (i.e., releasing water) of the core board layer.

[0018] In order to further better realize the non-deformable solid wood board material described in the present invention, the following setting method is particularly adopted: the reinforcing plate is made of a material with greater strength than the core bar and less deformation than the core bar, such as high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, carbon fiber, high-strength environmentally friendly chemical board, etc.

[0019] In order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: the core strip is obtained by cutting the quarter-sawn board or the carved board through the longitudinal cutting method of the board.

[0020] In order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: a splicing unit is arranged between two adjacent reinforcing structures, and the splicing unit includes a plurality of wooden square units arranged in a line; a reinforcing structure with small deformation and high strength is used to involve the deformation force of the splicing unit, so that the entire board is not easy to deform; a reinforcing plate is used to isolate the moisture crosstalk between the splicing units, so as to avoid deformation problems caused by the influence of moisture in the board; two surface layers can also be glued on the upper and lower surfaces of the splicing unit by using a glue layer using hot pressing or cold pressing technology.

[0021] In order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: in the length direction of the core strip, the ratio between the length of the core strip and the length of each wooden square unit is 300~3600:20~200.

[0022] Preferably, the wooden square unit is a rectangular body with a length, width, height (thickness) ratio of 20-200:20-200:10-30. Further preferably, the length, width, height (thickness) ratio of the wooden square unit can be 20:20:10, 50:60:15, or 200:200:30, etc., but is not limited thereto. The height of the wooden square 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., but is not limited thereto.

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

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

[0026] In order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the positional relationship between a pair of the reinforcing structures and the splicing units is: core bar-reinforcement board-core bar-splicing unit-core bar-reinforcement board-core bar.

[0027] In order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: the wooden square unit is obtained by cutting the quarter-sawn board or the carved board or the tangentially-sawn board in a double-cutting manner.

[0028] In order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the splicing unit may be composed of multiple reinforcing structures arranged in a line, and the reinforcing structure includes two core bars and a reinforcing plate sandwiched between the two core bars. The reinforcing plate is made of a material with greater strength than the core bar and less deformation than the core bar. The core bar is obtained by cutting the board longitudinally by using a radially cut board or a carved board.

[0029] In order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: the wood grain of the wooden square unit intersects with the reinforcement structure at 80°~90°.

[0030] In order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: a reinforcing plate is also provided on the periphery of the non-deformable solid wood board.

[0031] In order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: it also includes panel layers respectively arranged on both sides of the core board layer.

[0032] In order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: a reinforcing net is arranged between the panel layer and the core board layer.

[0033] In order to further better realize the non-deformable solid wood board of the present invention, the following arrangement is particularly adopted: the reinforcing mesh and the reinforcing board are arranged perpendicularly.

[0034] In order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the reinforcing mesh uses a grid material with a deformation amount smaller than the core bar and a strength greater than the core bar, such as glass fiber grid, aluminum grid, carbon fiber grid, GRC reinforced grid, etc.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects: Since the present invention provides reinforcing plates with greater strength and smaller deformation than the core bars between the core bars, the entire reinforced structure can be kept substantially in a non-deformed state under the pulling of the reinforcing plates and the optimized control of humidity.

[0036] The present invention arranges a reinforcing plate in the core plate layer so as to prevent moisture from converging between the core strips on both sides of the reinforcing plate, thereby avoiding deformation of the entire plate due to water absorption or desorption.

[0037] The present invention provides a reinforcing plate between the core bars of the core plate layer, which can further increase the strength and rigidity of the core plate layer and avoid deformation.

[0038] The present invention adopts a splicing unit composed of a reinforcement structure and multiple wooden units, and uses the reinforcement structure with small deformation and high strength to involve the deformation force of the splicing unit, so that the entire board is not easy to deform; and compared with the present invention that uses all reinforcement structures, the cost of the board itself is also reduced accordingly, which can meet the needs of customers at different price points.

[0039] The present invention utilizes a reinforcing plate to isolate moisture crosstalk between the splicing units, thereby avoiding deformation problems caused by moisture in the plate.

[0040] The present invention adopts the method of combining the reinforced structure horizontally and vertically, which can avoid the deformation of the plate to the greatest extent.

[0041] The present invention adopts a cross-splicing (especially orthogonal splicing) design structure of the splicing unit composed of a reinforcement structure and multiple wooden square units, and adopts a small unit design mode to guide the deformation of the splicing unit to the reinforcement structure, thereby ensuring the optimal stability of the entire board.

[0042] The core strip of the reinforcing structure of the present invention is a board square (solid wood) obtained by cutting a board longitudinally by a quarter-sawn board or a carved board, and the wood square unit is a board square (solid wood) obtained by cutting a board double-cut by a quarter-sawn board or a carved board or a tangentially cut board. When the wood square unit is spliced ​​with the reinforcing structure, the wood grain of the wood square unit intersects with the reinforcing structure at 80°~90°, thereby minimizing the possibility of deformation of the entire board due to deformation of the wood square unit.

[0043] Due to the cutting method of the wooden square units and the arrangement method between the reinforcement structures (the wood of the wooden square units is arranged to intersect the reinforcement structure at 80°~90° along the grain), the most likely deformation is in the direction of the reinforcement structure. However, since the reinforcement structure is in a basically non-deformable state, the deformation of the wooden square units in the direction of the reinforcement structure is involved, thereby making the entire board less likely to deform.

[0044] The present invention solves the deformation problem of existing solid wood boards by changing the water absorption and release units of the solid wood boards from a whole board structure into a plurality of small unit structures spaced apart from each other, thereby making the entire solid wood board as free from deformation as possible.

[0045] The present invention provides a reinforcing net between the core board layer and the panel layer, which can enhance the strength of the solid wood board in thickness and avoid deformation of the board due to insufficient strength.

[0046] The present invention can enhance the strength and rigidity of the core board layer itself while also enhancing the strength and rigidity of the entire solid wood board, thereby overcoming the disadvantage of easy deformation of existing solid wood boards, and is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0067] Glossary: Cross-cut boards: refers to boards obtained by cutting in a direction perpendicular to the main axis of the tree trunk.

[0068] Tangentially sawn boards refer to boards that are sawn along the main axis of the trunk, that is, along the grain of the wood and perpendicular to the radius of the trunk section.

[0069] Quarter-sawn lumber is a lumber produced by sawing a timber pile into four parts, which are then cut into the quarters.

[0070] Carving boards is a process of evenly cutting the wood into four parts and then finely sawing each part to obtain a part of the board close to the heartwood.

[0071] Cross section: One of the three basic sections of wood, this section is perpendicular to the long axis of the trunk. It is also called an end section, cross section, or annual ring section. This section reveals the wood's growth rings, heartwood, sapwood, earlywood and latewood, wood rays, and pores. It is the most important section for identifying wood.

[0072] Radial section: One of the three basic sections of wood, this section is a longitudinal section along the long axis of the trunk, through the pith and parallel to the rays or perpendicular to the growth rings. This section reveals parallel growth rings or growth ring lines, the color of the sapwood and heartwood, the arrangement of vessels or tracheid lines along the grain, and the rays.

[0073] Tangential section: One of the three basic sections of wood, it refers to a longitudinal section along the main axis of the trunk, perpendicular to the rays or parallel to the growth rings. Like the radial section, the tangential section is a longitudinal section, perpendicular to each other. On the tangential section, the growth rings are parabolic, allowing the height and width of the rays to be measured.

[0074] Double cutting method of plates: refers to the reprocessing of various plates by combining the processing methods of cross cutting and longitudinal cutting.

[0077] Wood grain is the expression of the orientation of the axial molecules (such as wood fibers, tracheids, and vessels) within the wood. It can be categorized as straight, oblique, spiral, wavy, and interlaced.

[0078] The annual ring plane refers to the plane on which the wood rings are located.

[0079] The grain of wood refers to the direction in which the wood grows towards the treetop, which is basically perpendicular to the annual rings.

[0080] Example 1: The non-deformable solid wood board comprises a core board layer, wherein the core board layer comprises a plurality of reinforcing structures 9 arranged side by side. The small unit splicing mode is adopted to overcome the defect of the existing solid wood board that is easy to deform, and the board is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors.

[0081] As a preferred design solution, the non-deformable solid wood board, such as Figure 1 、 Figure 2 、 Figure 3As shown, it includes a core plate layer, which is composed of multiple reinforcing structures 9 arranged side by side. Adjacent reinforcing structures 9 are glued together using a glue layer using hot pressing or cold pressing technology.

[0082] Example 2: This embodiment is further optimized on the basis of the above embodiment, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially adopted: the reinforcement structure 9 includes two core strips 3 and a reinforcement plate 4 sandwiched between the two core strips 3; the reinforcement 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 a preferred design solution, combined with Figure 1 、 Figure 2 As shown, the reinforcement structure 9 includes two core bars 3 and a reinforcement plate 4 sandwiched between the two core bars 3. When set, the core bars 3 and the reinforcement plate 4 are glued together through the glue layer using hot pressing or cold pressing technology. The reinforcement plate 4 is set between the core bars 3 and the core bars 3. It can increase the strength of the reinforcement structure formed by the simple core bars 3 and change the deformation of the reinforcement structure formed by the simple core bars 3, thereby avoiding deformation.

[0084] Example 3: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially 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] Combine Figure 1 、 Figure 2 As shown, as a preferred design scheme, the reinforcing plate 4 adopts a material with greater strength than the core bar 3 and less deformation than the core bar 3, such as carbon fiber, aluminum alloy, high-strength environmentally friendly plywood, aluminum plate, multi-layer wood, high-strength environmentally friendly chemical plate, etc., so that the deformation of the entire reinforcing structure 9 is restricted by the reinforcing plate 4, thereby avoiding deformation of the reinforcing structure 9 to the greatest extent.

[0086] Example 4: This embodiment is further optimized based on any of the above embodiments, and the similarities with the above technical solutions are not repeated here. Figure 1 、 Figure 2As shown, in order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the core strip 3 is a solid wood obtained by cutting the quarter-sawn board or the carved board by the longitudinal cutting method of the board. Since the quarter-sawn board or the carved board itself is the board with the smallest deformation among several types of boards, the wood square obtained by cutting it by the longitudinal cutting method will also have a smaller deformation possibility, and due to the pulling force of the reinforcing board 4, the deformation of the entire structure becomes smaller, thereby achieving the purpose of not being easy to deform.

[0087] Example 5: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially adopted: a splicing unit is provided between two adjacent reinforcing structures 9, and the splicing unit includes a plurality of wooden square units 8 arranged in a line.

[0088] As a 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 line is arranged between the two reinforcing structures 9; an adhesive layer is arranged between the reinforcing structure 9 and the splicing unit, and an adhesive layer is arranged between the wooden square units 8.

[0089] Among them, the wooden square units 8 are glued together by hot pressing or cold pressing technology through the glue layer to form a splicing unit, and the splicing unit and the reinforcing structure 9 are also glued together by hot pressing or cold pressing technology through the glue layer. The splicing unit composed of the reinforcing structure and multiple wooden square units is spliced ​​together, and the reinforcing structure with small deformation and high strength is used to involve the deformation force of the splicing unit, so that the entire board is not easy to deform; and the reinforcing plate is also used to isolate the moisture crosstalk between the splicing units, so as to avoid the deformation problem caused by the influence of moisture in the board.

[0090] The two surface layers can be glued together on the upper and lower surfaces of the splicing unit by using a glue layer through hot pressing or cold pressing technology.

[0091] Example 6: This embodiment is further optimized based on any of the above embodiments, and the similarities with the above technical solutions are not repeated here. Figure 1 、 Figure 2 、 Figure 3As shown, to further improve the non-deformable solid wood board of the present invention, the following configuration is particularly adopted: the wooden square unit 8 is a rectangular body with a length, width, height (thickness) ratio of 20-200:20-200:10-30. Furthermore, preferably, the length, width, height (thickness) ratio of the wooden square unit can be 20:20:10, or 50:60:15, or 200:200:30, etc., but not limited to these. This facilitates the splicing of the wooden square units 8 and effectively ensures that the strength is not affected. The height of the wooden square unit is the same as the thickness of the core strip.

[0092] Typically, the length of the wooden square unit 8 can be 20mm, 40mm, 50mm, 60mm, 80mm, 100mm, 120mm, 150mm, 160mm, 180mm, 200mm; the width of the wooden square unit can be 20mm, 40mm, 50mm, 60mm, 80mm, 100mm, 120mm, 150mm, 160mm, 180mm, 200mm; the height (thickness) of the wooden square unit 8 can be 30mm, 24mm, 20mm, 16mm, 14mm, 12mm, 10mm, etc. Example 7: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly 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 wooden square unit 8 is 300~3600:20~200.

[0093] As a 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 wooden square unit 8 is 300~3600:20~200. A plurality of wooden square units are glued together by an adhesive layer to form a splicing unit. Since the wooden square unit is a small unit structure, the deformation of a single (root or block) will be smaller, so the deformation of the splicing unit formed may also become smaller. Combined with the pulling force of the reinforced structure, the deformation possibility of the entire board becomes smaller.

In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially adopted: the positional relationship between a pair of the reinforcing structures 9 and the splicing unit is: core bar 3-reinforcement board 4-core bar 3-splicing unit-core bar 3-reinforcement board 4-core bar 3.

[0101] As a 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 bar 3-reinforcement plate 4-core bar 3-splicing unit-core bar 3-reinforcement plate 4-core bar 3. In the specific arrangement, a glue layer is also provided between the core bar 3 and the reinforcing plate 4, and between the core bar 3 and the splicing unit, and then they are hot-pressed or cold-pressed together using hot-pressing or cold-pressing technology to form the entire plate.

[0102] Example 9: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially adopted: in the direction in which the core strip 3 and the reinforcing plate 4 of the reinforcing structure 9 are arranged, at least one edge skin 10 is provided, which is in contact with the core strip 3 and has a strength ≤ that of the reinforcing plate 4, and the deformation amount of the edge skin 10 ≤ that of the reinforcing plate 4.

[0103] As a preferred design solution, combined with Figure 1 、 Figure 2 、 Figure 3As shown, in the direction in which the core strip 3 and the reinforcing plate 4 of the reinforcing structure 9 are arranged, at least one (or block) of the side skin 10 is in contact with the core strip 3 and has a strength ≤ that of the reinforcing plate 4, and the deformation of the side skin 10 ≤ that of the reinforcing plate 4. In the specific arrangement, an adhesive layer is provided between the side skin 10 and the core strip 3, and an adhesive layer is provided between the side skin 10 and the reinforcing plate 4, and they are hot-pressed or cold-pressed together using hot-pressing or cold-pressing technology; since the strength of the side skin 10 and the reinforcing plate 4 are both better than that of the core strip 3, and the deformation is both smaller than that of the core strip 3, the entire reinforcing structure 9 is less likely to deform.

[0104] Example 10: This embodiment is further optimized based on any of the above embodiments, and the similarities with the above technical solutions are not repeated here. Figure 1 、 Figure 2 、 Figure 3 As shown, in order to better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the wooden square unit 8 is obtained by cutting the quarter-sawn board or the carved board or the tangentially-sawn board using a double-cutting method.

[0105] The core strip 3 in the reinforcing structure 9 is a board (solid wood) obtained by cutting the board longitudinally by using a quarter-sawn board or a carved board, and the wood square unit 8 is a board (solid wood) obtained by cutting the board double-cut by using a quarter-sawn board or a carved board or a tangentially cut board. When the wood square unit 8 is spliced ​​with the reinforcing structure 9, the wood grain of the wood square unit 8 intersects with the reinforcing structure 9 at 80°~90°, thereby minimizing the deformation of the wood square unit that causes deformation of the entire board.

[0106] Example 11: This embodiment is further optimized based on any of the above embodiments, and the similarities with the above technical solutions are not repeated here. Figure 1 、 Figure 2 、 Figure 3 As shown, in order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the splicing unit is composed of multiple reinforcing structures 9 arranged in a line, and 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 strip 3 and less deformation than the core strip 3. The core strip 3 is obtained by cutting the board longitudinally by using a radially cut board or a carved board.

[0107] As a preferred design solution, the splicing units can also be constructed using a reinforcement structure 9. This reinforcement structure 9 also uses a structure consisting of two core strips 3 sandwiching a reinforcement plate 4. The reinforcement plate 4 is made of a material that is stronger than the core strip 3 and less deformable than the core strip 3. The core strip 3 is cut longitudinally from quarter-sawn or scored boards. Compared to the non-deformable solid wood board constructed using the splicing units of the wooden square units 8, while the cost is higher, the strength is higher and the possibility of deformation is reduced.

[0108] As a preferred design scheme, the splicing unit can also adopt a combined structure in which the reinforcing structure 9 and the wooden square unit 8 are arranged in a line: for example, 1 piece (root) of reinforcing structure is adjacent to 1 piece (root) of wooden square unit 8, 1 piece (root) of reinforcing structure is adjacent to 2 pieces (root) of wooden square units 8, etc. When cutting, the reinforcing structure 9 and the wooden square unit 8 in the splicing unit have the same size specifications.

[0109] Example 12: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially adopted: the wood grain of the wooden square unit 8 intersects with the reinforcement structure 9 at 80°~90°.

[0110] As a preferred design solution, combined with Figure 1 、 Figure 2 、 Figure 3 As shown, the wood grain of the wooden square unit 8 is intersected with the reinforcing structure 9 at 80°~90°, for example, at 80°, 82°, 85°, 88°, 90°, etc., so that the annual ring surface is in contact with the reinforcing structure 9, so that the deformation force of the wooden square unit 8 in the direction of the reinforcing structure is restrained by the reinforcing structure, thereby achieving the purpose of preventing the entire board from being easily deformed.

[0111] When the wooden square unit 8 is a cube or a cuboid, it is generally assumed that the wood grain and the annual ring surface are respectively on two intersecting planes of the cube or cuboid, and the wood grain and the annual ring surface are almost in a vertical intersection state, so that the standard setting of the wood grain of the wooden square unit 8 and the reinforcement structure 9 intersecting at 80°~90° can be achieved in this article.

[0112] Example 13: This embodiment is further optimized based on any of the above embodiments, and the similarities with the above technical solutions are not repeated here. Figure 1 、 Figure 2 、 Figure 3 As shown, in order to further better realize the non-deformable solid wood board of the present invention, the following setting method is particularly adopted: a reinforcing plate 4 is also provided on the periphery of the non-deformable solid wood board.

[0113] As a preferred design solution, a circle of reinforcing plate 4 is also glued to the periphery of the non-deformable solid wood board by hot pressing or cold pressing.

[0114] Example 14: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board of the present invention, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the following arrangement is particularly adopted: it also includes panel layers respectively arranged on both sides of the core plate layer, and an adhesive layer is arranged between the panel layer and the core plate layer.

[0115] As a preferred design solution, in order to further enhance the strength and rigidity of the entire solid wood board, panel layers are glued to both sides of the core board layer through adhesive layers using hot pressing or cold pressing technology.

[0116] Example 15: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board of the present invention, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the following arrangement is particularly adopted: a reinforcing mesh is arranged between the face plate layer and the core plate layer.

[0117] As a preferred design scheme, in order to further enhance the strength and rigidity of the entire solid wood board, a reinforcing net is provided between the panel layer and the core board layer; the panel layer and the reinforcing net are bonded with an adhesive layer, and the reinforcing net and the core board layer are bonded with an adhesive layer. During processing and production, the panel layer, the reinforcing net and the core board layer can be further compacted by hot pressing or cold pressing.

[0118] The present invention further fixes the core board layer by reinforcing plates and reinforcing nets, 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 wood absorbing and releasing moisture.

[0119] Example 16: This embodiment is further optimized on the basis of any of the above embodiments, and the similarities with the above technical solutions are not repeated here. In order to better realize the non-deformable solid wood board of the present invention, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the following arrangement is particularly adopted: the reinforcing mesh and the reinforcing plate are arranged vertically.

[0120] As a preferred design scheme, the positional relationship between the reinforcing net and the reinforcing plate 4 in the solid wood board is: the multiple layers (blocks) of reinforcing plates 4 are arranged in parallel in the space formed by the two reinforcing nets, so that any layer (block) of reinforcing plates 4 forms an I-shaped structure with the two reinforcing nets. In this way, the I-shaped structure can better increase the strength of the solid wood board and reduce the deformation.

[0121] Example 17: This embodiment is further optimized based on any of the above embodiments, and the similarities with the above technical solutions are not repeated here. Figure 1 、 Figure 2 、 Figure 3 As shown, in order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the reinforcing mesh adopts a grid material with a deformation amount smaller than the core bar and a strength greater than the core bar, such as glass fiber grid, aluminum grid, carbon fiber grid, GRC reinforced grid, etc.

[0122] As a preferred design solution, both reinforcement meshes are made of mesh materials with a smaller deformation than the core bar 3 and a stronger strength than the core bar 3, such as glass fiber mesh, aluminum mesh, carbon fiber mesh, GRC reinforcement mesh, etc.

[0123] Preferably, when the entire non-deformable solid wood board adopts the wooden square unit 8 as the splicing unit, the outermost periphery of the entire non-deformable solid wood board is the reinforcement structure 9.

[0124] Example 18: The non-deformable solid wood board adopts a small unit splicing mode to overcome the shortcoming of the existing solid wood board that is easy to deform. It is particularly suitable for furniture door panels such as wardrobe doors and cabinet doors. It includes a core board layer. The core board layer includes multiple core strips arranged side by side and reinforcement plates sandwiched between the core strips. The reinforcement plates are used to divide the entire core board layer into multiple small units, so that the water absorption area of ​​the core strip 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.

[0125] As a 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, and a core board layer 7 is arranged between panel A1 and panel B6, wherein the core board layer 7 includes multiple core strips 3 arranged side by side. In order to increase the rigidity and strength of the core board layer 7, multiple (strips or blocks) reinforcing plates 4 are arranged between the core strips 3, that is, one, two, three or four strips can be used as a small unit and separated by a (strip or block) reinforcing plate 4.

[0126] During the setting, in order to make the core strip 3 and the reinforcing plate 4 in the core board layer 7 be better combined together, the core strip 3 and the reinforcing plate 4 are bonded together with an adhesive layer. Further, during processing, a hot pressing or cold pressing process can be used to tightly bond the adhesive layer to the core strip 3 and the reinforcing plate 4, making the entire core board layer 7 tighter.

[0127] To solve the deformation problem of existing solid wood boards, the water absorption and release units of the solid wood boards are changed from a whole board structure to multiple small unit structures spaced apart from each other, so that the entire solid wood board can be as free from deformation as possible.

[0128] A reinforcing plate is provided in the core plate layer so as to prevent moisture from converging between the core strips on both sides of the reinforcing plate, thereby avoiding deformation of the entire plate due to water absorption or desorption.

[0129] Providing reinforcing plates between the core strips of the core plate layer can further increase the strength and rigidity of the core plate layer and avoid deformation.

[0130] Example 19: This embodiment is further optimized on the basis of the above embodiment, and the similarities with the above technical solution are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is specially adopted: a reinforcing plate is set between two adjacent core strips 3.

[0131] As a preferred design solution, combined with Figure 4 、 Figure 5 As shown, a core strip 3 is arranged to be separated by a reinforcing plate 4.

[0132] Example 20: This embodiment is further optimized on the basis of embodiment 18 or 19, and the similarities with the aforementioned technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: a reinforcing plate 4 is also provided on the periphery of the non-deformable solid wood board.

[0133] As a preferred design solution, combined with Figure 4 、 Figure 5 As shown, a circle of reinforcing plate 4 is also glued to the periphery of the non-deformable solid wood board by hot pressing or cold pressing.

[0134] Example 21: This embodiment is further optimized on the basis of embodiment 18, 19 or 20, and the similarities with the aforementioned technical solutions are not repeated here. In order to better realize the non-deformable solid wood board material described in the present invention, the following setting method is particularly adopted: it also includes panel layers respectively arranged on both sides of the core board layer 7, and an adhesive layer is arranged between the panel layer and the core board layer 7.

[0135] As a preferred design solution, Figure 4 、 Figure 5 As shown, in order to further enhance the strength and rigidity of the entire solid wood board, a panel layer A1 and a panel layer B6 are respectively glued to both sides of the core board layer 7 through glue layers using hot pressing or cold pressing technology.

[0136] Example 22: This embodiment is further optimized on the basis of embodiment 18 or 19 or 20 or 21, and the similarities with the aforementioned technical solutions are not repeated here. In order to better realize the non-deformable solid wood board material described in the present invention, the following setting method is specially adopted: a reinforcing net is also provided between the panel layer and the core board layer 7; an adhesive layer is provided between the reinforcing net and the core board layer 7, and an adhesive layer is also provided between the reinforcing net and the panel layer.

[0137] As a preferred design solution, Figure 4 、 Figure 5 As shown, in order to further enhance the strength and rigidity of the entire solid wood board, a reinforcing mesh A2 is provided between the face plate A1 and the core plate layer 7, and a reinforcing mesh B5 is provided between the core plate layer 7 and the face plate layer B6.

[0138] Panel A1 and reinforcing mesh A2 are bonded with an adhesive layer, reinforcing mesh A2 and core board layer 7 are bonded with an adhesive layer, core board layer 7 and reinforcing mesh B5 are bonded with an adhesive layer, and reinforcing mesh B5 and panel B6 are bonded with an adhesive layer. During processing and production, hot pressing or cold pressing technology can be further used to compact panel A1, reinforcing mesh A2, core board layer 7, reinforcing mesh B5 and panel B6.

[0139] The present invention further fixes the core board layer through the reinforcement plate and the reinforcement net, 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 wood absorbing and releasing moisture; after long-term experiments, the solid wood board with the reinforcement plate and the reinforcement net has greatly improved the deformation resistance compared with the solid wood board without the reinforcement plate and the reinforcement net, and under the same gravity, the improvement is about 3.5 times.

[0140] Example 23: This embodiment is further optimized on the basis of embodiment 18 or 19 or 20 or 21 or 22, and the similarities with the aforementioned technical solutions are not repeated here. In order to better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the reinforcing mesh and the reinforcing plate 4 are arranged vertically.

[0141] As a preferred design solution, combined with Figure 4 、 Figure 5As shown, the positional relationship among the reinforcing mesh A2, the reinforcing mesh B5 and the reinforcing plate 4 in the solid wood board is as follows: multiple layers (blocks) of reinforcing plates 4 are arranged in parallel in the space formed by the reinforcing mesh A2 and the reinforcing mesh B5, so that any layer (block) of reinforcing plates 4 forms an I-shaped structure with the reinforcing mesh A2 and the reinforcing mesh B5. In this way, the I-shaped structure can better increase the strength of the solid wood board and reduce the deformation.

[0142] Example 24: This embodiment is further optimized on the basis of embodiment 18 or 19 or 20 or 21 or 22 or 23, and the same points as the above technical solutions are not repeated here. Figure 4 、 Figure 5 As shown, in order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly adopted: the core strip 3 is a solid wood obtained by cutting the quarter-sawn board or the carved board by the longitudinal cutting method of the board. Since the quarter-sawn board or the carved board itself is the board with the smallest deformation among several types of boards, the wood square obtained by cutting it by the longitudinal cutting method will also have a smaller deformation possibility, and due to the pulling force of the reinforcing board 4, the deformation of the entire structure becomes smaller, thereby achieving the purpose of not being easy to deform.

[0143] Example 25: This embodiment is further optimized on the basis of embodiment 18 or 19 or 20 or 21 or 22 or 23 or 24, and the same points as the above technical solutions are not repeated here. Figure 4 、 Figure 5 As shown, in order to further better realize the non-deformable solid wood board described in the present invention, the following setting method is particularly 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.

[0144] As a preferred design scheme, 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 plate, etc., so that the deformation of a single small unit (core strip 3 + reinforcing plate 4 + core strip 3) is restricted by the reinforcing plate 4, thereby minimizing the deformation of the small unit and further avoiding the deformation of the entire plate.

[0145] Example 26: This embodiment is further optimized on the basis of embodiment 18 or 19 or 20 or 21 or 22 or 23 or 24 or 25, and the similarities with the aforementioned technical solutions are not repeated here. In order to better realize the non-deformable solid wood board material described in the present invention, the following setting method is specially adopted: the reinforcing mesh adopts a grid material with a deformation amount smaller than the core bar 3 and a strength greater than the core bar 3, such as a glass fiber grid, an aluminum grid, a carbon fiber grid, a GRC reinforced grid, etc.

[0146] As a preferred design solution, combined with Figure 4 、 Figure 5 As shown, the reinforcing mesh A2 and the reinforcing mesh B5 both use mesh materials with less deformation than solid wood and greater strength than solid wood, such as glass fiber mesh, aluminum mesh, carbon fiber mesh, GRC reinforced mesh, etc.

[0147] Example 27: Solid wood board that is not easy to deform, combined with Figure 4 、 Figure 5 As shown, including the top (according to the attached Figure 4 、 5 The panel A1 of the next layer (viewing angle), the reinforcing mesh A2 of the next layer, the core board layer 7 of the next layer, the reinforcing mesh B5 of the next layer, and the panel B6 of the bottom layer; wherein the core board layer 7 is composed of multiple core strips 3 and reinforcing plates 4 sandwiched between the core strips 3 and the core strips 3. The positional relationship of the reinforcing mesh A2, the reinforcing mesh B5 and the reinforcing plates 4 in the solid wood board is as follows: multiple layers (blocks) of reinforcing plates 4 are arranged in parallel in the space formed by the reinforcing mesh A2 and the reinforcing mesh B5, so that any layer (block) of reinforcing plates 4 forms an I-shaped structure with the reinforcing mesh A2 and the reinforcing mesh B5. In this way, the I-shaped structure can better increase the strength of the solid wood board and reduce the deformation.

[0148] Since reinforcing mesh A2 and reinforcing mesh B5 are provided in the thickness, and reinforcing plates 4 are provided between the core strips 3 of the core board layer 7, the strength and rigidity of the entire solid wood board are greatly improved, thereby avoiding deformation.

[0149] like Figure 6 As shown, the non-deformable solid wood board of the present invention was placed outdoors and remained unchanged for 9 days under the high temperature of 37 degrees in summer.

[0150] like Figure 7 As shown, the non-deformable solid wood board of the present invention is subjected to alternating hot and cold conditions, and then its hot and cold shrinkage data are measured.

[0151] like Figure 8 As shown, the non-deformable solid wood board of the present invention is compared with other boards in the same industry by soaking in water. It is obvious that the other boards in the same industry have great deformation, while the board of the present invention (indicated by the red arrow in the figure) has no obvious deformation.

[0152] like Figure 9 As shown, the non-deformable solid wood board of the present invention is soaked in water to perform a water soaking test.

[0153] like Figure 10 As shown, ordinary boards will obviously warp after being exposed to the sun for a long time.

[0154] like Figure 11 As shown, the actual state of the purchased brand solid wood board after being placed outdoors for 106 days is compared with the real state of the non-deformable solid wood board of the present invention after being placed outdoors for 146 days.
