[0001] The present invention relates to a wooden panel joint structure. [Background technology]

[0002] 2. Description of the Related Art Joining structures for joining wooden panel materials using finger joints are known (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2-38003 [Patent Document 2] JP 2010-214703 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the techniques disclosed in Patent Documents 1 and 2, the edges of the wooden surface material need to be zigzag-shaped, which makes processing the wooden surface material time-consuming. In addition, since large-scale equipment is required, the wooden surface material can only be processed in a factory, and the size of the wooden surface material is limited to the size that can be transported.

[0005] In consideration of the above, the present invention aims to improve the manufacturability of the first wood panel and the second wood panel while enabling them to be joined. [Means for solving the problem]

[0006] According to the first aspectThe wood panel joining structure comprises a first wood panel having a plurality of first long wood boards stacked in the width direction of the panel, a second wood panel having a plurality of second long wood boards stacked in the width direction of the panel, a first uneven portion formed at the end of the first wood panel by shifting the ends of the plurality of first long wood boards in the longitudinal direction, and a second uneven portion formed at the end of the second wood panel by shifting the ends of the plurality of second long wood boards in the longitudinal direction, and joined in a combined state with the first uneven portion.

[0007] First aspect According to the wood panel joining structure, the first wood panel has a plurality of first long wood boards stacked in the width direction of the panel, and the second wood panel has a plurality of second long wood boards stacked in the width direction of the panel.

[0008] A first uneven portion is formed on an end of the first wood panel. A second uneven portion is formed on an end of the second wood panel. The second uneven portion is joined in a combined state with the first uneven portion.

[0009] Here, the first uneven portion is formed by longitudinally shifting the ends of the first long wood boards, and the second uneven portion is formed by longitudinally shifting the ends of the second long wood boards.

[0010] In this way, in the present invention, the ends of the first long wood boards are shifted in the longitudinal direction, so that the first uneven portion can be easily formed on the end of the first wood panel. Similarly, in the present invention, the ends of the second long wood boards are shifted in the longitudinal direction, so that the second uneven portion can be easily formed on the end of the second wood panel. Therefore, the manufacturability of the first wood panel and the second wood panel is improved.

[0011] Furthermore, in the present invention, since no large-scale equipment is required for processing the first uneven portion and the second uneven portion, the first uneven portion and the second uneven portion can be processed on the first wood panel and the second wood panel, respectively, at a work site, for example.

[0012] Therefore, there is no need to consider size restrictions for the transportation of the first and second wooden surface materials. In addition, the present invention makes it possible to join (split board) the first and second wooden surface materials at a factory or on-site that does not have joint equipment.

[0013] According to the second aspect The wooden surface material joint structure is as follows: According to the first aspect The wood panel joining structure includes a wedge-shaped member that fills the gap between the side surfaces of the first uneven portion and the second uneven portion.

[0014] Second aspect According to the above-mentioned wood panel joining structure, the gap between the side surfaces of the first and second uneven portions is filled with a wedge-shaped member, so that the first and second uneven portions can be easily joined together. Also, the efficiency of stress transmission between the first and second uneven portions is improved.

[0015] According to the third aspect The wooden surface material joint structure is as follows: First aspect or According to the second aspect The wood panel joining structure includes a screw for joining the first uneven portion and the second uneven portion.

[0016] Third aspect According to the wood panel joining structure, the first uneven portion and the second uneven portion are joined with screws, so that the first uneven portion and the second uneven portion can be easily joined. Also, the efficiency of stress transmission between the first uneven portion and the second uneven portion is improved. Effect of the Invention

[0019] Hereinafter, a wooden panel joining structure according to one embodiment will be described.

[0020] (Wood panel joint structure) 1, the wood surface material joining structure according to this embodiment includes adjacent first and second wood floor slabs 10A and 10B, and a plurality of wedge-shaped members 60. The first wood floor slab 10A is an example of a first wood surface material, and the second wood floor slab 10B is an example of a second wood surface material.

[0021] The first wood floor slab 10A and the second wood floor slab 10B are formed in a plate shape using nail laminated timber (NLT) and are arranged adjacent to each other. Each of the first wood floor slab 10A and the second wood floor slab 10B has a plurality of long wooden boards 12.

[0022] The first and second wood flooring slabs 10A and 10B may be formed in a plate shape using DLT (Dowel Laminated Timber) instead of NLT. The arrow X shown in each figure indicates the longitudinal direction of the long wood board 12. The arrow Y indicates the width direction (hereinafter referred to as the "surface material width direction") of the first and second wood flooring slabs 10A and 10B.

[0023] The long wooden board 12 is, for example, a standardized wooden board (two-by lumber, one-by lumber, etc.) used in the two-by-four construction method (frame wall construction method) etc. The long wooden board 12 is a long member having a rectangular cross section.

[0024] 2 and 3, the multiple long wooden boards 12 of the first wood flooring 10A are arranged with their respective board thickness directions aligned with the width direction (direction of arrow Y) of the surface material of the first wood flooring 10A. These long wooden boards 12 are joined by multiple nails 14 in a state where they are stacked in the width direction of the surface material of the first wood flooring 10A.

[0025] 4, the multiple long wooden boards 12 of the second wood flooring 10B are arranged with their thickness direction aligned with the width direction of the surface material of the first wood flooring 10A (direction of arrow Y). These long wooden boards 12 are stacked in the width direction of the surface material of the first wood flooring 10A and joined by multiple nails (not shown).

[0026] The long wood board 12 of the first wood flooring 10A is an example of a first long wood board, and the long wood board 12 of the second wood flooring 10B is an example of a second long wood board.

[0027] A first uneven portion 20A is formed at the end (the end in the direction of arrow X) of the first wood flooring 10A. The first uneven portion 20A has convex portions 30 and concave portions 40 that are arranged alternately in the width direction of the surface material of the first wood flooring 10A. This first uneven portion 20A is formed by shifting the longitudinal ends 12E of multiple long wood boards 12 in the longitudinal direction of the long wood boards 12.

[0028] Specifically, the protruding portion 30 is formed in a rectangular shape when viewed from the thickness direction of the first wooden floor slab 10A. This protruding portion 30 is formed by three long wooden boards 12 joined together with their ends 12E aligned, i.e., with their ends 12E positioned in the same position. Note that the phrase "positioning the ends 12E of the long wooden boards 12 in the same position" here is a concept that also includes a configuration in which the ends 12E of the long wooden boards 12 are misaligned due to construction errors, etc.

[0029] The recess 40 is formed in a rectangular shape when viewed from the thickness direction of the first wood flooring 10A by partially recessing the end of the first wood flooring 10A. The recess 40 is formed by shifting the positions of the ends 12E of the three long wood boards 12 in the longitudinal direction relative to the ends 12E of the three long wood boards 12 that form the protrusion 30.

[0030] The first uneven portion 20A may be formed by shifting long wooden boards 12 of the same length in the longitudinal direction, or by combining long wooden boards 12 of different lengths. The number of long wooden boards 12 forming the protrusions 30 and recesses 40 can be changed as appropriate. Furthermore, the protrusions 30 and recesses 40 can be formed by at least one long wooden board 12.

[0031] A second uneven portion 20B is formed at the end of the second wooden flooring 10B. The second uneven portion 20B has convex portions 30 and concave portions 40 that are alternately arranged in the width direction of the surface material of the first wooden flooring 10A. The convex portions 30 and concave portions 40 of this second uneven portion 20B are formed in the opposite phase to the convex portions 30 and concave portions 40 of the first uneven portion 20A. This allows the first uneven portion 20A and the second uneven portion 20B to be combined. In other words, the first uneven portion 20A and the second uneven portion 20B are combined in a state in which one convex portion 30 is fitted into the other concave portion 40 and the other convex portion 30 is fitted into the one concave portion 40.

[0032] The method for forming the convex portions 30 and the concave portions 40 of the second concave-convex portion 20B is similar to that for the convex portions 30 and the concave portions 40 of the first concave-convex portion 20A.

[0033] (Wedge-shaped member) 5, when the first concave-convex portion 20A and the second concave-convex portion 20B are combined, a groove 50 is formed between the side surfaces 30S of adjacent convex portions 30. The groove 50 is formed by combining notches 52 formed in the side surfaces 30S of adjacent convex portions 30. The groove 50 is formed in a triangular cross section with the groove width narrowing toward the bottom of the groove.

[0034] The grooves 50 are formed so as not to reach the undersides of the first wood flooring 10A and the second wood flooring 10B. The grooves 50 are formed only on one side (upper surface) in the thickness direction of the first wood flooring 10A and the second wood flooring 10B. A wedge-shaped member 60 is driven into the grooves 50.

[0035] 6, the wedge-shaped member 60 is formed, for example, from ultra-dried wood material. Ultra-dried wood material is a wood material that is dried by artificial drying or the like so as not to dry and shrink after construction. The moisture content of this ultra-dried wood material is lower than that of general dried wood material (about 20%), and is, for example, 5 to 8%.

[0036] The wedge-shaped member 60 is not limited to being made of ultra-dried wood material, and may be made of, for example, dried wood material. Also, the wedge-shaped member 60 may be made of, for example, metal or resin that does not shrink when dried.

[0037] The wedge-shaped member 60 is formed in a thin plate shape with a triangular cross section. The wedge-shaped member 60 is arranged along a groove 50 formed between adjacent convex portions 30, and is driven into the groove 50 from the side of the pointed tip portion 60T. As a result, the side surfaces 60S on both sides of the wedge-shaped member 60 are pressed against the inner side surfaces 50S of the groove 50, respectively, and the gap between the side surfaces of the first uneven portion 20A and the second uneven portion 20B, i.e., the gap between the side surfaces 30S of the convex portions 30 adjacent in the width direction of the face material, is filled. As a result, the first uneven portion 20A and the second uneven portion 20B are pressed against each other via the wedge-shaped member 60.

[0038] In this embodiment, the wedge-shaped members 60 are driven into both sides of the protrusion 30, but it is also possible to drive the wedge-shaped members 60 into only one side of the protrusion 30. The wedge-shaped members 60 can also be driven into at least one of both sides (upper and lower surfaces) in the thickness direction of the first wood flooring 10A and the second wood flooring 10B. Furthermore, the arrangement and number of the wedge-shaped members can be changed as appropriate.

[0039] In addition, the end 12E opposite to the tip 60T of the wedge-shaped member 60 protrudes from the groove 50. The end 60E of this wedge-shaped member 60 may be embedded in a finishing material such as a self-leveling material provided on the first wood flooring 10A and the second wood flooring 10B, or may be covered and hidden by a double floor formed on the first wood flooring 10A and the second wood flooring 10B. The end 60E of the wedge-shaped member 60 may also be cut off.

[0040] (action) Next, the operation of this embodiment will be described.

[0041] According to the wood floor joint structure of this embodiment, the first wood floor 10A is formed of multiple long wood boards 12 joined together while stacked in the width direction of the surface material. Similarly, the second wood floor 10B is formed of multiple long wood boards 12 joined together while stacked in the width direction of the surface material.

[0042] A first uneven portion 20A is formed at an end of the first wooden floor slab 10A. A second uneven portion 20B is formed at an end of the second wooden floor slab 10B. This second uneven portion 20B is joined in a combined state with the first uneven portion 20A.

[0043] 2 and 3, the first wood flooring 10A and the second wood flooring 10B are formed by stacking a number of long wood boards 12 in the width direction of the surface material and driving a number of nails 14 into the boards. Therefore, for example, the size of the first wood flooring 10A and the second wood flooring 10B can be easily adjusted on-site. Furthermore, by using standardized products such as two-by-one lumber or one-by-one lumber as the long wood boards 12, material costs can be reduced.

[0044] The first uneven portion 20A is formed by shifting the end 12E of the long wood boards 12 in the longitudinal direction when stacking the multiple long wood boards 12. Similarly, the second uneven portion 20B is formed by shifting the end 12E of the long wood boards 12 in the longitudinal direction when stacking the multiple long wood boards 12. This improves the manufacturability of the first wood flooring 10A and the second wood flooring 10B.

[0045] Furthermore, in this embodiment, since no large-scale equipment is required to process the first uneven portion 20A and the second uneven portion 20B, the first uneven portion 20A and the second uneven portion 20B can be easily formed in the first wood floor slab 10A and the second wood floor slab 10B, for example, at an on-site or the like.

[0046] Therefore, there is no need to consider size restrictions for transportation of the first wood floor slab 10A and the second wood floor slab 10B. In addition, in this embodiment, the first wood floor slab 10A and the second wood floor slab 10B can be joined (jointed) at a factory or on-site that does not have joint equipment.

[0047] Furthermore, when the first and second wooden floor slabs 10A and 10B do not bear earthquake forces, the joint positions (board joint positions) of the first and second uneven portions 20A and 20B are not limited to being on beams, etc., and can be freely set, thus improving design freedom.

[0048] 6, in this embodiment, a wedge-shaped member 60 is driven into a groove 50 between the side surfaces 30S of the first uneven portion 20A and the second uneven portion 20B. The wedge-shaped member 60 fills the gap between the side surfaces 30S of the first uneven portion 20A and the second uneven portion 20B, making it possible to easily join the first uneven portion 20A and the second uneven portion 20B.

[0049] Moreover, since stress is transmitted by bearing pressure and friction between the first concave-convex portion 20A and the second concave-convex portion 20B via the wedge-shaped member 60, the efficiency of stress transmission is improved.

[0050] Furthermore, the wedge-shaped members 60 are driven into grooves 50 formed in the upper surfaces of the first wood flooring 10A and the second wood flooring 10B, and do not protrude from the lower surfaces of the first wood flooring 10A and the second wood flooring 10B. This improves the design of the lower surfaces of the first wood flooring 10A and the second wood flooring 10B.

[0051] In this manner, in this embodiment, the first wood flooring 10A and the second wood flooring 10B can be easily joined together while improving the design of the undersides of the first wood flooring 10A and the second wood flooring 10B.

[0052] Furthermore, in this embodiment, the wedge-shaped member 60 is formed of an ultra-dried wood material. This prevents the wedge-shaped member 60 from drying and shrinking after being driven into the groove 50 between the side surfaces 30S of the first uneven portion 20A and the second uneven portion 20B. This prevents the joint strength of the first uneven portion 20A and the second uneven portion 20B from decreasing due to seasonal changes, etc.

[0053] Moreover, by forming the wedge-shaped member 60 from a wooden material (wooden material), for example, on-site processing becomes easy, improving workability.

[0054] (Modification) Next, a modification of the above embodiment will be described.

[0055] 7, protrusions 62 are formed on both side surfaces 60S of a wedge-shaped member 60. The protrusions 62 are driven into the groove 50 while being deformed, for example. This allows the wedge-shaped member 60 to be reliably pressed against the inner side surface 50S of the groove 50.

[0056] In the above embodiment, the first uneven portion 20A and the second uneven portion 20B are joined by the wedge-shaped member 60. However, for example, as in the modified example shown in Fig. 8 and Fig. 9, the first uneven portion 20A and the second uneven portion 20B may be joined by screws 70, 72.

[0057] The screws 70 are screwed obliquely into the convex portions 30 adjacent in the width direction of the surface material from the surface side of the first wood flooring 10A and the second wood flooring 10B. The screws 72 are screwed obliquely into the tops of the opposing convex portions 30 and the bottoms of the concave portions 40 from the surface side of the first wood flooring 10A and the second wood flooring 10B. The first uneven portion 20A and the second uneven portion 20B are joined together by these screws 70, 72.

[0058] By using the screws 70 and 72 in this manner, the first concave-convex portion 20A and the second concave-convex portion 20B can be easily joined together.

[0059] The number and arrangement of the screws 70, 72 can be changed as appropriate. The screws 70, 72 can be screwed in from at least one of the top and bottom surfaces of the first wood floor slab 10A and the second wood floor slab 10B.

[0060] In the above embodiment, the first wooden surface material is the first wooden floor slab 10A, and the second wooden surface material is the second wooden floor slab 10B. However, the first wooden surface material and the second wooden surface material are not limited to wooden floor slabs, and may be, for example, a wooden ceiling material or a wooden wall material.

[0061] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it is of course possible to implement the present invention in various forms without departing from the gist of the present invention.
