Description
[Technical Field]
[0001] The present invention relates to a wooden panel formed by laminating a plurality of sliced veneers and bonding them together with an adhesive, and to a wooden structure using this wooden panel. [Background technology]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-159251 [Patent Document 2] Japanese Patent Publication No. 2020-079545 Summary of the Invention [Problem to be solved by the invention]
[0005] An object of the present invention is to provide a wooden panel that is easily deformed by bending, twisting, and the like, and a wooden structure that uses this wooden panel. [Means for solving the problem]
[0006] The inventors came up with the idea that by stacking three to twelve sheets of veneer with a thickness of 0.2 mm to 4 mm as a wood surface material, with adhesive tape or adhesive sheet sandwiched between them, it is possible to ensure a large adhesive area between the joining surfaces of the veneers, thereby improving adhesive strength and preventing separation of the veneers from each other, and this is what led to the present invention. The wood panel material of the first invention is a wood panel material (e.g., wood panel material 30 described below) formed by stacking multiple veneers (e.g., veneer 31 described below) and adhering them to each other with an adhesive (e.g., adhesive material 32 described below), characterized in that the veneers are thin plates carved out of wood to a thickness of 0.2 mm to 4 mm, the adhesive is an adhesive tape or adhesive sheet coated with an acrylic adhesive, and 3 to 12 sheets of the veneers are stacked and pressure-bonded to each other with the adhesive.
[0007] The minimum number of veneers was set at three to ensure structural strength, with one veneer layered above and below each other. Based on knowledge gained from research and development into wood surface materials, the maximum number of veneers was set at 12 to minimize variations in structural strength. According to this invention, a wooden panel is formed by laminating three to twelve slices of veneer with a thickness of 0.2 mm to 4 mm, and then bonding these slices together with an adhesive. Because thin, flexible sheets that are easy to bend are used as the slices, the wooden panel made by laminating multiple slices of veneer can be easily deformed by bending and twisting, making it possible to create complex shapes and curved surfaces using the wooden panel.
[0008] Furthermore, because many veneers are layered and joined together with adhesive, the wood panel has many adhesive layers. Therefore, when a shear force is applied to the wood panel in the longitudinal direction, the shear force is borne by each adhesive layer, allowing the wood panel to accommodate large shear deformation. Furthermore, since the multiple sliced veneers are pressure-bonded together with an adhesive, the bonding area between the joining surfaces of the sliced veneers is increased, improving the adhesive strength and preventing the sliced veneers from separating from each other. The number of veneers used was between 3 and 12. By stacking a certain number of veneers in this way, it is possible to reduce variations in the quality of each veneer and each adhesive layer, resulting in a wood surface material with approximately uniform quality.
[0009] The wood panel material of the second invention is characterized in that at least one of the plurality of veneer panels is arranged with its fiber direction substantially perpendicular to that of the remaining veneer panels.
[0010] According to this invention, at least one of the multiple veneer panels is arranged so that its fiber direction is approximately perpendicular to the remaining veneer panels. This improves strength and rigidity compared to when all the veneer panels are arranged so that their fiber directions are approximately parallel, making it possible to apply the veneer to a wider range of wooden structures.
[0011] The wooden structure of the third invention is a wooden structure (for example, wooden structures 1, 1A, 1C described below) constructed by combining a plurality of wooden shaft members (for example, column members 21, 21C and beam members 22, 22A, 22C described below) with a plurality of the above-mentioned wooden surface members, characterized in that the wooden shaft members extend in a predetermined direction and are arranged side by side approximately parallel to each other, and the wooden surface members extend in a direction intersecting the wooden shaft members within the plane formed by the wooden shaft members and are attached to the wooden shaft members so as to pass alternately on the front and back sides of the arranged wooden shaft members.
[0012] According to this invention, by arranging a plurality of wooden shafts side by side and attaching wooden face materials to the wooden shafts so that they alternately pass over the front and back sides of the wooden shafts, a planar truss structure can be formed with the wooden shafts and wooden face materials. Therefore, by combining the wooden shafts and wooden face materials, a wooden structure with excellent strength and rigidity can be realized, and a load-bearing wall can be constructed. Furthermore, since the wooden face materials are attached to the wooden shaft material so as to pass alternately on the front and back sides of the wooden shaft material, the wooden face materials are integrated with the wooden shaft material, improving the strength and rigidity of the wooden structure.
[0013] The wooden structure of the fourth invention is a wooden structure (for example, wooden structure 1B described below) constructed by combining a pair of wooden shaft members (for example, wooden shaft member 24 described below) and a plurality of the above-mentioned wooden surface members, characterized in that the wooden shaft members extend in a predetermined direction and are arranged approximately parallel to each other, the wooden surface members extend in a mesh-like pattern in directions that intersect with each other within the plane formed by the wooden shaft members, and both ends of the wooden surface members are attached to the wooden shaft members.
[0014] According to this invention, the wooden surface materials are arranged in a mesh pattern in a direction intersecting each other, thereby realizing a wooden structure with excellent strength and rigidity, and enabling the construction of a bearing wall. Furthermore, since both ends of the wooden face material are attached to the wooden structure, the wooden face material is integrated with the wooden shaft material, improving the strength and rigidity of the wooden structure.
[0015] The wooden structure of the fifth invention is a wooden structure (for example, wooden structure 1D described below) constructed by combining a plurality of wooden shaft members (for example, column members 21 and beam members 22 described below) and the above-mentioned wooden surface members, characterized in that the wooden shaft members extend in a predetermined direction and are arranged approximately parallel to each other, and the wooden surface members extend in a direction intersecting the wooden shaft members within the plane formed by the wooden shaft members and are attached to the wooden shaft members so as to pass continuously along the front or back sides of some adjacent wooden shaft members.
[0016] According to this invention, by arranging a plurality of wooden shafts side by side and attaching wooden face materials to the wooden shafts so that they run continuously along the front or back sides of the wooden shafts, the wooden face materials can be used as resistance elements for in-plane shear forces. Therefore, by combining the wooden shafts and wooden face materials, a wooden structure with excellent strength and rigidity can be realized, and a shear wall can be constructed. Furthermore, since the wooden face material is attached to the wooden shaft material so as to pass continuously along the front and back sides of the wooden shaft material, the wooden face material is integrated with the wooden shaft material, improving the strength and rigidity of the wooden structure. [Effects of the Invention]
[0017] According to the present invention, it is possible to provide a wooden panel that is easily deformed by bending, twisting, and the like, and a wooden structure that uses this wooden panel. [Brief explanation of the drawings]

[0019] The present invention relates to a wooden surface material made by laminating three to twelve layers of veneer having a thickness of 0.2 mm to 4 mm with adhesive tape or adhesive sheet sandwiched between them, and to a wooden structure constructed from the wooden surface material and a wooden shaft material.Specific forms of wooden structures using the wooden surface material include wooden structures (first and second embodiments) in which the wooden surface material is used as a component of a truss structure or arch structure to prevent bending stress from acting on the wooden surface material, and wooden structures (third and fifth embodiments) in which the wooden surface material is used as a resisting element for in-plane shear force. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the embodiments, the same components will be denoted by the same reference numerals, and the description thereof will be omitted or simplified. [First embodiment] Fig. 1 is a side view of a wooden structure 1 according to a first embodiment of the present invention. Fig. 2 is an AA cross-sectional view of the wooden structure 1 in Fig. 1. Fig. 3(a) is a BB cross-sectional view of the wooden structure 1 in Fig. 1, and Fig. 3(b) is a CC cross-sectional view of the wooden structure 1 in Fig. 1. Fig. 4 is a side view of a portal frame 20 of the wooden structure 1. Fig. 5 is a perspective view of a portion surrounded by a dashed line D of the portal frame 20 in Fig. 4. The wooden structure 1 of the first embodiment forms a planar frame structure by alternately curving adjacent wooden surface materials 30 sandwiching the column members 21 and beam members 22 between multiple wooden shaft members 21 and beam members 22.
[0020] The wooden structure 1 comprises a plurality of foundation blocks 10 arranged in two rows in the girder direction on the ground surface 4, a plurality of portal frames 20 erected on the foundation blocks 10, and a plurality of long wooden surface materials 30 connecting the portal frames 20 together. The foundation block 10 is made of reinforced concrete and has anchor bolts 11 buried in it. The portal frame 20 comprises a pair of column members 21 as wooden shaft members, and beam members 22 as wooden shaft members that connect the column capitals of these column members 21. The column members 21 extending vertically are arranged side by side in the girder direction, thereby forming the side surface 2 of the wooden structure 1. The beam members 22 extending between the beams are also arranged side by side in the girder direction, thereby forming the top surface 3 of the wooden structure 1.
[0021] Each of the pillar member 21 and the beam member 22 includes two flat plate members 40 that are substantially parallel to each other, and a base 41 that connects these two flat plate members 40. The flat plate members 40 have a rectangular cross section and are solid wood formed by cutting wood. The base 41 is provided on the portion of the pillar member 21 and the beam member 22 to which the wooden surface material 30 is attached. The flat plate material 40 of the pillar member 21 is joined to the anchor bolt 11 of the foundation block 10. At the joint between the column head of the column member 21 and both ends of the beam member 22, one of the two flat plate materials 40 of the column member 21 is sandwiched between two flat plate materials 40 of the beam member 22, and one of the two flat plate materials 40 of the beam member 22 is sandwiched between two flat plate materials 40 of the column member 21, and these four flat plate materials 40 are joined together with four drift pins 42.
[0022] On the side surface 2 of the wooden structure 1, the wooden panel materials 30 extend in the girder direction intersecting the column members 21 within the side surface 2 formed by the multiple column members 21, and are arranged in a row in the vertical direction. Each wooden panel material 30 is flexible and is attached by bending it in a wave shape so that it passes alternately over the front and back sides of the column members 21 arranged side by side. In other words, for adjacent column members 21, it passes over the front side of one column member 21 and then over the back side of the other column member 21. Furthermore, for each pillar member 21, the wooden surface materials 30 arranged in the vertical direction are arranged so as to pass alternately on the front side or the back side of this pillar member 21.
[0023] Similarly, on the top surface 3 of the wooden structure 1, the wooden panel materials 30 extend in the longitudinal direction intersecting the beam members 22 within the top surface 3 formed by the multiple beam members 22, and are arranged side by side in the span direction. Each wooden panel material 30 is flexible and is attached by bending it in a wave shape so that it passes alternately above or below the beam members 22 arranged side by side. In other words, for adjacent beam members 22, it passes above one beam member 22 and then below the other beam member 22. Furthermore, for each beam member 22, the wooden surface materials 30 arranged in the inter-beam direction are arranged so as to pass alternately above or below this beam member 22.
[0024] 6(a) is a front view of the base 41 of the portal frame 20, and FIG. 6(b) is a cross-sectional view of the base 41 of the portal frame 20. As shown in FIG. The base 41 is fixed to the flat plate material 40 of the pillar member 21 and the beam member 22 with screws 43. The outer surface 41A of the base 41 is curved to match the shape of the wooden surface material 30, and the wooden surface material 30 is fixed to this outer surface 41A with screws 44. Fig. 7(a) is an enlarged view of a portion of the wooden structure 1 in Fig. 1 surrounded by a dashed line E. Fig. 7(b) is a cross-sectional view taken along line FF of Fig. 7(a). 7, a pair of wedges 45A and 45B extending in the vertical direction are provided facing each other at the intersections of the vertically aligned wooden panel panels 30. These wedges 45A and 45B are attached to the wooden panel panels 30 with screws 46.
[0025] Fig. 8 is a perspective view of the wooden panel material 30. Fig. 9(a) is a schematic cross-sectional view of the wooden panel material 30. The wood surface material 30 is formed by stacking multiple veneers 31 and adhering them to each other with adhesive material 32. The veneers 31 are carved from cedar or oak wood to a thickness of 0.2 mm to 4 mm, and are stacked in layers of 3 to 12 sheets, which are pressure-bonded to each other with adhesive material 32. All of the veneers 31 are arranged so that their fiber directions are approximately parallel. For example, the fiber direction of all of the veneers 31 is set to be the length direction of the veneers 31. The adhesive material 32 is an adhesive tape or an adhesive sheet coated with an acrylic adhesive.
[0026] Specifically, for example, the wood panel 30 is made by laminating seven slices of veneer 31 and forming six layers of adhesive material 32, and is 1800 mm long, 300 mm wide, and 9 mm thick. The slices 31 are carved out of cedar wood to a thickness of 1 mm. The adhesive material 32 is Nitoms' Handycut multi-purpose strong double-sided tape 50 x 10 (product number J1340). As shown in FIG. 9( b ), when a shear force P acts on the wooden panel 30 in the longitudinal direction, the adhesive layer made of the adhesive material 32 deforms and follows the shear deformation of the wooden panel 30 .
[0027] The procedure for constructing the wooden structure 1 will be described below with reference to the flowchart of FIG. In step S1, as shown in FIG. 11, a foundation block 10 is placed on the ground surface 4. In step S2, as shown in Fig. 12, each portal frame 20 is assembled on the ground surface 4, and the assembled portal frames 20 are lifted by a crane or the like (not shown) and placed on the foundation blocks 10. At this time, the portal frames 20 are temporarily fixed to each other by temporary braces 23 or the like. In step S3, the wooden panel 30 is attached to the portal frame 20.
[0028] According to this embodiment, the following effects are obtained. (1) Three to twelve sheets of veneer 31, each having a thickness of 0.2 mm to 4 mm and carved from cedar or oak, are laminated together, and these veneers 31 are pressure-bonded together with adhesive 32 to form a wooden panel 30. Because thin, flexible boards that are easy to bend are used as the veneers 31, the wooden panel 30, which is made by laminating multiple sheets of veneer 31, is easily deformed by bending and twisting, making it possible to construct complex shapes and curved surfaces using the wooden panel 30. In other words, the wooden panel 30 is made by bonding thin wooden panels 31 together with sheet-like adhesive 32, and the adhesive layers between the veneers 31 allow for large shear deformation, so the wooden panel 30 can be easily bent and twisted. Furthermore, since many veneers 31 are stacked and joined together with adhesive material 32, many adhesive layers are formed on the wood panel 30. Therefore, when a shear force is applied to the wood panel 30 in the length direction, the shear force is borne by each adhesive layer, allowing the wood panel 30 to accommodate large shear deformation. Furthermore, since the plurality of veneer sheets 31 are pressure-bonded together with the adhesive material 32, the bonding area is increased, the bonding strength between the bonding surfaces of the veneer sheets 31 is improved, and separation of the veneer sheets 31 from each other can be prevented. In addition, three to twelve veneer boards 31 were used. By stacking a relatively large number of veneer boards 31 in this way, it is possible to reduce variations in the quality of each veneer board 31 and each adhesive layer, and to form a wood surface material 30 with approximately uniform quality.
[0029] (2) The wooden panel 30 alone is flexible and easy to bend, but has low rigidity and strength, and therefore has not been used as a structural member. However, by arranging multiple column members 21 and beam members 22 side by side and attaching the wooden panel 30 so that it passes alternately on the front and back sides of these column members 21 and beam members 22, a wooden structure 1 with excellent strength and rigidity can be realized, and a load-bearing wall can be constructed. Furthermore, since the wooden surface material 30 is attached so as to pass through the front and back sides of the column members 21 and beam members 22, the wooden surface material 30 is integrated with the column members 21 and beam members 22, improving the strength and rigidity of the wooden structure 1.
[0030] Second Embodiment Fig. 13 is a side view of a portal frame 20A of a wooden structure 1A according to a second embodiment of the present invention, Fig. 14 is a perspective view of a portion of the portal frame 20A in Fig. 13 surrounded by a dashed line G. In this embodiment, the configuration of a beam member 22A of a portal frame 20A is different from that of the first embodiment. That is, the beam member 22A includes a single flat plate material 40 and a base 41 provided on this flat plate material 40. 15 is a cross-sectional view of a base 41 attached to a beam member 22A. In this embodiment, the base 41 is fixed to a single flat plate material 40 of the beam member 22 with a screw 43, as shown in FIG. According to this embodiment, the same effects as those of (1) and (2) above are obtained.
[0031] Third Embodiment Fig. 16 is a partially enlarged view of the side surface 2 or the top surface 3 of a wooden structure 1B according to a third embodiment of the present invention, and Fig. 17 is a cross-sectional view of the wooden structure 1B of Fig. 16 taken along line HH. In this embodiment, the arrangement of the wood panel 30 differs from that of the second embodiment. That is, the side surface 2 or the top surface 3 of the wooden structure 1B is constructed by combining a pair of wooden shaft members 24 and a plurality of wooden surface members 30. The wooden shafts 24 extend in a predetermined direction and are arranged side by side substantially parallel to one another. The wooden face materials 30 are woven in a mesh-like pattern extending in directions intersecting each other within the plane of the wooden shaft material 24, and both ends of these wooden face materials 30 are attached to the wooden shaft material 24. The wooden structure 1B (wooden shear wall) of the third embodiment has a structure in which multiple wooden face materials 30 are woven into the front and back of the wooden shaft 24, so that the wooden face materials are scattered on both sides of the shear wall. Therefore, the wooden face materials 30 are alternately crossed between a pair of wooden shafts 24 to form a shear wall that is a planar frame. Therefore, in this shear wall, the wooden face materials 30 serve as shear resistance elements. According to this embodiment, in addition to the above-mentioned effect (1), the following effect is obtained.
[0032] (3) The wooden face panels 30 are arranged in a mesh pattern in a direction intersecting each other, so that the wooden structure 1B has excellent strength and rigidity, and a bearing wall can be constructed. Furthermore, since both ends of the wooden surface material 30 are attached to the wooden structure 1B, the wooden surface material 30 is integrated with the wooden shaft material 24, improving the strength and rigidity of the wooden structure 1B.
[0033] [Fourth embodiment] Fig. 18 is a side view of a portal frame 20C of a wooden structure 1C according to a fourth embodiment of the present invention. Fig. 19 is a cross-sectional view taken along line II of the portal frame 20C in Fig. 18. Fig. 20 is a perspective view of a portion of the portal frame 20C in Fig. 18 surrounded by a dashed line J. The base is not shown in Fig. 19. In this embodiment, the configuration of a portal frame 20C is different from that of the first embodiment. That is, the portal frame 20C includes a pair of pillar members 21C and beam members 22C that connect the column capitals of these pillar members 21C. The column bases of the pillar members 21C of the portal frame 20C are connected to each other by floor beams 60, and the column capitals of the pillar members 21C of the portal frame 20C are connected to each other by beam members 61.
[0034] The pillar member 21C and the beam member 22C are configured to include four long shaft members 50 and connecting members 51 interposed between the four shaft members 50 to join the shaft members 50 together. At the joint between the column head of column member 21C and both ends of beam member 22C, the two shaft members 50 of column member 21C are sandwiched between the four shaft members 50 of beam member 22C, and the two shaft members 50 of beam member 22C are sandwiched between the four shaft members 50 of column member 21C. The floor beams 60 and the girder members 61 are sandwiched between the four shaft members 50 of the column members 21C. According to this embodiment, the same effects as those of (1) and (2) above are obtained.
[0035] Fifth Embodiment Fig. 21 is a side view of a wooden structure 1D according to a fifth embodiment of the present invention. Fig. 22 is a KK cross-sectional view and an LL cross-sectional view of the wooden structure 1D in Fig. 21. Fig. 23 is an enlarged view and a cross-sectional view of a part surrounded by a dashed line M in the wooden structure 1D in Fig. 21. This embodiment differs from the first embodiment in that the wooden panel 30 passes continuously along the front or back sides of some of the adjacent column members 21.
[0036] That is, in the first embodiment, the wooden surface materials 30 are attached so as to pass alternately over the front or back sides of the column members 21 arranged side by side, but in this embodiment, for some adjacent column members 21, the wooden surface materials 30 are attached so as to pass continuously over the front or back sides of the column members 21. In other words, some of the wooden surface materials 30 are not curved, but form straight portions 33 that extend in a straight line (shown by diagonal lines in Figure 21). Furthermore, in this embodiment, the pillar member 21 is not provided with a base 41 as in the first embodiment, and the wooden surface material 30 is directly fixed to the flat plate material 40 of the pillar member 21 and the beam member 22 with screws 43. The curved portion of the wooden surface material 30 is fixed to the flat plate material 40 with two screws 43, and the straight portion 33 of the wooden surface material 30 is fixed to the flat plate material 40 with six screws 43. According to this embodiment, in addition to the above-mentioned effect (1), the following effect is obtained.
[0037] (4) By arranging a plurality of column members 21 and beam members 22 side by side and attaching the wooden panel 30 so that it runs continuously along the front or back sides of these column members 21 and beam members 22, the wooden panel 30 can be used as a resistance element for in-plane shear forces. Therefore, by combining the column members 21 and beam members 22 with the wooden panel 30, a wooden structure 1D with excellent strength and rigidity can be realized, and a load-bearing wall can be constructed. Furthermore, since the wooden surface material 30 is attached so as to pass continuously along the front and back sides of the column members 21 and beam members 22, the wooden surface material 30 is integrated with the column members 21 and beam members 22, improving the strength and rigidity of the wooden structure 1D.
[0038] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. For example, in each of the above-described embodiments, the veneer is carved from cedar or oak, but this is not limiting, and the type of wood from which the veneer is carved is not limited. For example, the veneer may be carved from softwood such as cypress or Japanese cypress, or hardwood such as beech, birch, or chestnut. In the above-described embodiments, all of the veneers 31 are arranged so that their fiber directions are substantially parallel. However, this is not limiting. At least one of the multiple veneers 31 constituting the wood panel 30 may be arranged so that its fiber direction is perpendicular to that of the remaining veneers 31. For example, as shown in FIG. 24 , the fiber directions of the second-highest and second-lowest veneers 31A are arranged so that they are substantially perpendicular to the fiber direction of the remaining veneer 31B. In other words, the fiber direction of veneer 31B is the length direction of veneer 31B, and the fiber direction of veneer 31A is the width direction of veneer 31A. This arrangement improves strength and rigidity compared to when all of the veneers 31 are arranged so that their fiber directions are substantially parallel, making it applicable to a wider range of wooden structures.
[0039] In each of the above-described embodiments, the wooden surface material 30 is arranged on the side surface 2 and the top surface 3 of the wooden structure 1, but this is not limited to this, and the wooden surface material 30 may be arranged only on the side surface 2 of the wooden structure 1 or only on the top surface 3 of the wooden structure 1. In addition, in each embodiment, solid wood cut from wood is used as the flat plate material 40 that constitutes the wooden shaft material (21, 21C, 22, 22A, 22C, 24), but this is not limited to this, and the flat plate material may also be medium-density fiberboard (MDF), which is formed by cutting wood plywood or wood into small pieces and chemically bonding them with an adhesive.
