Description

[Technical field]

[0001] The present invention relates to a wall plate. [Background technology]

[0002] 2. Description of the Related Art Wooden walls constructed by connecting a plurality of wooden wall panels are known (see, for example, Patent Documents 1 to 3).

[0003] The board wall disclosed in Patent Document 1 includes a plurality of wooden wall boards (single boards) arranged in the vertical direction between adjacent pillars, and a plurality of bars connecting the wooden wall boards. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2000-192574 A [Patent Document 2] JP 2012-052324 A [Patent Document 3] JP 2017-218793 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the wooden wall disclosed in Patent Document 1, multiple wooden wall panels connected by multiple bars are installed between adjacent pillars during construction. In this case, gaps are formed between the pillars and the wooden wall panels to absorb construction errors, etc. Therefore, during an earthquake, the wooden wall panels are likely to rattle between the adjacent pillars, and the initial rigidity of the wooden wall may decrease.

[0006] One possible solution to this problem is to install wooden wall panels between adjacent pillars without leaving any gaps, but this requires a lot of work to install the wooden wall panels.

[0007] In consideration of the above-mentioned facts, the present invention aims to suppress a decrease in the initial rigidity of a board wall while improving workability. [Means for solving the problem]

[0008] The board wall described in claim 1 comprises a plurality of first wooden wall boards arranged in the vertical direction between a pair of adjacent pillars, a plurality of second wooden wall boards arranged in the vertical direction between the pair of pillars and adjacent to each of the plurality of first wooden wall boards in the wall width direction, a connecting wall board arranged in notches formed in one end sides of the adjacent first wooden wall boards and second wooden wall boards, respectively, and spanning the plurality of first wooden wall boards and second wooden wall boards arranged in the vertical direction, and a plurality of connecting members penetrating the connecting wall board in the wall thickness direction and connecting the one end sides of the first wooden wall boards and the second wooden wall boards to the connecting wall board, respectively.

[0009] According to the board wall of claim 1, the first wooden wall boards are arranged vertically between a pair of adjacent columns, and the second wooden wall boards are arranged vertically between a pair of adjacent columns and are adjacent to each of the first wooden wall boards in the wall width direction.

[0010] A notch is formed on one end of each of the adjacent first and second wooden wall panels. A connecting wall panel is disposed in the notch. The connecting wall panel spans the first and second wooden wall panels arranged in the vertical direction. The connecting wall panel and the first and second wooden wall panels are connected by a connecting member that penetrates the connecting wall panel in the wall thickness direction.

[0011] In this way, in the present invention, the first and second wooden wall panels adjacent to each other in the wall width direction are connected via a connecting wall panel. Therefore, for example, by adjusting the connection positions of the first and second wooden wall panels and the connecting wall panel, it is possible to eliminate or reduce the gap between the pair of columns and the first and second wooden wall panels. Therefore, rattling of the board wall during an earthquake is suppressed, and a decrease in the initial rigidity of the board wall is suppressed.

[0012] In addition, after arranging a plurality of first and second wooden wall panels between a pair of columns, these first and second wooden wall panels can be connected via a connecting wall panel, so that a wooden wall can be easily installed between the pair of columns, thereby improving the workability of the wooden wall.

[0013] In this way, the present invention can improve workability while suppressing a decrease in the initial rigidity of the board wall.

[0014] The board wall described in claim 2 is the board wall described in claim 1, wherein the one end sides of the adjacent first wooden wall board and the adjacent second wooden wall board are formed as a notched joint that sandwiches the connecting wall board from both sides in the wall thickness direction.

[0015] According to the board wall of claim 2, one end side of the adjacent first wooden wall board and second wooden wall board is a notched joint that sandwiches the connecting wall board from both sides in the wall thickness direction. This allows the connecting wall board to be covered and hidden by one end side of the adjacent first wooden wall board and second wooden wall board. This improves the design of the board wall.

[0016] A board wall according to a third aspect of the present invention is the board wall according to the first or second aspect, wherein the first wooden wall board and the second wooden wall board adjacent to each other in a width direction of the wall extend over side surfaces of a pair of the pillars.

[0017] According to the board wall of claim 3, the first and second wooden wall boards adjacent to each other in the width direction of the wall extend over the side surfaces of a pair of columns. In other words, in the present invention, the other ends of the first and second wooden wall boards are in contact with the side surfaces of the pair of columns. This further suppresses the rattling of the board wall during an earthquake. Therefore, the decrease in the initial rigidity of the board wall is further suppressed. Effect of the Invention

[0018] As described above, according to the present invention, it is possible to improve workability while suppressing a decrease in the initial rigidity of a board wall. [Brief description of the drawings]

[Figure 6] 4 is a cross-sectional view corresponding to FIG. 2 and showing a modified example of a plate wall according to one embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, a board wall according to one embodiment will be described with reference to the drawings.

[0021] (frame) 1 shows a frame 10 provided with a plank wall 20 according to this embodiment. The frame 10 is, as an example, a wooden frame. The frame 10 has a pair of adjacent columns 12 and upper and lower beams 16 erected on the pair of columns 12.

[0022] The pair of pillars 12 and the upper and lower beams 16 are made of wood or wood material. The pair of pillars 12 are formed with a rectangular cross section (prism-like shape) and are arranged with their respective side surfaces 12S facing each other. Grooves 14 are formed in the side surfaces (opposing surfaces) 12S of the pair of pillars 12, respectively.

[0023] The pair of grooves 14 face each other in the wall width direction (arrow W direction) of the board wall 20. Each groove 14 extends in the vertical direction along the side surface 12S of the pillar 12, spanning the upper and lower beams 16. The other ends 30E, 40E of a first wooden wall board 30 and a second wooden wall board 40, which will be described later, are fitted into the pair of grooves 14.

[0024] The upper and lower beams 16 are formed in a rectangular cross section and are erected on a pair of columns 12 with a gap between them in the height direction (vertical direction) of the board wall 20. The board wall 20 is provided within the structural surface of the frame 10 configured in this manner.

[0025] (Wallboard) As shown in Fig. 2, the plank wall 20 is, for example, an earthquake-resistant wall or a load-bearing wall. This plank wall 20 has a plurality of first wooden wall panels 30, a plurality of second wooden wall panels 40, a connecting wall panel 50, and a plurality of connecting pins 60. Note that the plank wall 20 is not limited to an earthquake-resistant wall or a load-bearing wall, and may be a miscellaneous wall such as a partition wall. Also, the connecting pin 60 is an example of a connecting member.

[0026] (Daiichi wooden wall board) The first wooden wall boards 30 are made of wood or wood material, and are arranged between a pair of pillars 12. The first wooden wall boards 30 are formed into board shapes with the wall width direction (arrow W direction) of the board wall 20 as the longitudinal direction. These first wooden wall boards 30 are arranged with the wall thickness direction (board thickness direction) of the board wall 20 as the wall thickness direction.

[0027] The first wooden wall boards 30 are stacked and arranged in the vertical direction. The first wooden wall boards 30 are arranged close to one of the pair of columns 12. One end side 30A of each of the first wooden wall boards 30 is connected to one end side 40A of the second wooden wall board 40 via a connecting wall board 50 described later. Meanwhile, the other end side 30E of each of the first wooden wall boards 30 is fitted into a groove 14 formed in a side surface 12S of one of the columns 12.

[0028] (Second wooden wall board) The second wooden wall boards 40 are formed from wood or wood material, and are arranged between a pair of pillars 12. The second wooden wall boards 40 are formed in a plate shape with the wall width direction (arrow W direction) of the board wall 20 as the longitudinal direction. These second wooden wall boards 40 are arranged with the wall thickness direction of the board wall 20 as the wall thickness direction.

[0029] The second wooden wall boards 40 are stacked and arranged in the vertical direction. The second wooden wall boards 40 are arranged toward the other of the pair of columns 12. The other ends 40E of the second wooden wall boards 40 are fitted into the grooves 14 formed in the side surface 12S of the other column 12.

[0030] Here, the multiple first wooden wall boards 30 and the multiple second wooden wall boards 40 are arranged adjacent to each other in the wall width direction of the board wall 20. The adjacent first wooden wall boards 30 and the adjacent second wooden wall boards 40 have one end sides 30A, 40A that form a half-length joint and are connected via a connecting wall board 50 described later.

[0031] Specifically, notches 32, 42 are formed on one end sides 30A, 40A of the adjacent first wooden wall board 30 and second wooden wall board 40, respectively, in which the one end sides 30A, 40A of the other are disposed. The notches 32, 42 are formed on the surfaces (opposing surfaces) of the opposing first wooden wall board 30 and second wooden wall board 40, respectively. These notches 32, 42 make the wall thicknesses of the one end sides 30A, 40A of the first wooden wall board 30 and second wooden wall board 40 thinner than the wall thicknesses of the other end sides 30B, 40B.

[0032] A plurality of connecting holes 34 are formed on one end side 30A of the first wooden wall board 30. The plurality of connecting holes 34 are circular through-holes that penetrate one end side 30A of the first wooden wall board 30 in the wall thickness direction. These connecting holes 34 are arranged at intervals in the wall width direction and height direction of the board wall 20.

[0033] Similarly, a plurality of connecting holes 44 are formed on one end side 40A of the second wooden wallboard 40. The plurality of connecting holes 44 are circular through-holes that penetrate one end side 40A of the second wooden wallboard 40 in the wall thickness direction. These connecting holes 44 are spaced apart in the wall width and height directions of the board wall 20, and face the plurality of connecting holes 34 formed on one end side 30A of the first wooden wallboard 30, respectively.

[0034] (Connected wall plate) A connecting wall panel 50 is disposed between one end sides 30A, 40A of the first wooden wall panel 30 and the second wooden wall panel 40. The connecting wall panel 50 is formed, for example, from a steel plate or CLT (Cross Laminated Timber) and has higher rigidity than the first wooden wall panel 30 and the second wooden wall panel 40.

[0035] The connecting wallboard 50 is not limited to being made of steel plate or CLT, and may be made of other metal plate or wood material such as LVL (Laminated Veneer Lumber), laminated lumber, plywood, etc. The rigidity of the connecting wallboard 50 may be the same as that of the first wooden wallboard 30 and the second wooden wallboard 40, or may be lower than that of the first wooden wallboard 30 and the second wooden wallboard 40.

[0036] The connecting wall board 50 is sandwiched between one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 with its wall thickness direction being the wall thickness direction of the board wall 20. In addition, the connecting wall board 50 has a height (vertical width) greater than the first wooden wall board 30 and the second wooden wall board 40.

[0037] The connecting wall panel 50 is disposed across a plurality of first wooden wall panels 30 arranged in the vertical direction, and is also disposed across a plurality of second wooden wall panels 40 arranged in the vertical direction. The connecting wall panel 50 is also disposed across the upper and lower beams 16.

[0038] A plurality of connecting holes 54 are formed in the connecting wall panel 50. The connecting holes 54 are circular through-holes that penetrate the connecting wall panel 50 in the wall thickness direction. The connecting holes 54 are spaced apart in the wall width and height directions of the board wall 20, and communicate with a plurality of connecting holes 34, 44 formed in the one end sides 30A, 40A of the first wooden wall panel 30 and the second wooden wall panel 40, respectively. Connecting pins 60 are fitted into these connecting holes 34, 44, 54.

[0039] (Connecting pin) The multiple connecting pins 60 are, for example, rod-shaped members such as drift pins or round steel bars. The connecting pins 60 may be wooden members such as wooden dowels. The connecting pins 60 are driven into connecting holes 34, 44, 54 formed in one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40, and the connecting wall board 50. These connecting pins 60 connect the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 to each other via the connecting wall board 50.

[0040] The first wooden wall board 30 and the second wooden wall board 40 are arranged across the side surfaces 12S of the pair of columns 12, while being connected via the connecting wall board 50. More specifically, the first wooden wall board 30 and the second wooden wall board 40 are connected via the connecting wall board 50, and the other ends 30E, 40E of each of them are in contact with the bottom surfaces 14A of the grooves 14 formed in the side surfaces 12S of the pair of columns 12.

[0041] (How to construct wooden walls) Next, an example of a method for constructing the board wall 20 according to this embodiment will be described.

[0042] 3, first, a first wooden wall board 30 is placed between a pair of columns 12 from the out-of-plane direction of the frame 10, and the other end 30E of the first wooden wall board 30 is fitted into a groove 14 formed in a side surface of one of the columns 12. This procedure is repeated to stack and arrange a plurality of first wooden wall boards 30 in the vertical direction.

[0043] Next, the connecting wall panel 50 is placed between the pair of columns 12 from the out-of-plane direction of the frame 10, and the connecting wall panel 50 is placed in the notch 32 formed in one end side 30A of the plurality of first wooden wall panels 30. In this way, the connecting wall panel 50 is placed across the plurality of first wooden wall panels 30 arranged in the vertical direction.

[0044] Next, a second wooden wall panel 40 is placed between a pair of columns 12 from the out-of-plane direction of the frame 10, and one end side 40A of the second wooden wall panel 40 is overlapped with the connecting wall panel 50 while the other end portion 40E of the second wooden wall panel 40 is fitted into the groove 14 formed in the side surface 12S of the other column 12, as shown by the arrow.

[0045] As a result, as shown in Figure 4, the connecting wall panel 50 is placed in the notch 42 formed in one end side 40A of the second wooden wall panel 40, and the connecting wall panel 50 is sandwiched between one end side 40A of the second wooden wall panel 40 and one end side 30A of the first wooden wall panel 30.

[0046] This procedure is repeated to stack and vertically arrange a plurality of second wooden wall boards 40. In this way, the connecting wall board 50 is arranged across the plurality of second wooden wall boards 40 arranged in the vertical direction.

[0047] Next, connecting pins 60 are driven into the connecting holes 34, 44, 54 formed in the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 and the connecting wall board 50. This connects the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 to each other via the connecting wall board 50, and the board wall 20 is formed.

[0048] The above construction procedure can be modified as appropriate. For example, the connecting wall board 50 may be placed between a pair of columns 12 first, and then the first wooden wall board 30 and the second wooden wall board 40 may be stacked on both sides of the connecting wall board 50 in order. Also, for example, a pair of the first wooden wall board 30 and the second wooden wall board 40 adjacent to each other in the wall width direction of the board wall 20 may be stacked while being connected to the connecting wall board 50 in order by the connecting pin 60. Also, for example, a plurality of first wooden wall boards 30 and connecting wall boards 50 previously connected by a plurality of connecting pins 60 may be placed between a pair of columns 12, and then a plurality of second wooden wall boards 40 may be stacked and placed between the pair of columns 12.

[0049] (action) Next, the operation of this embodiment will be described.

[0050] According to this embodiment, the multiple first wooden wall boards 30 are arranged in the vertical direction between a pair of adjacent columns 12. The multiple second wooden wall boards 40 are arranged in the vertical direction between a pair of adjacent columns 12, and are adjacent to each of the multiple first wooden wall boards 30 in the wall width direction.

[0051] Notches 32, 42 are formed in one end sides 30A, 40A of the adjacent first wooden wall board 30 and second wooden wall board 40. A connecting wall board 50 is disposed in these notches 32, 42.

[0052] The connecting wall panel 50 is disposed across the plurality of first wooden wall panels 30 and second wooden wall panels 40 arranged in the vertical direction. The connecting wall panel 50 and the plurality of first wooden wall panels 30 and second wooden wall panels 40 are connected by connecting pins 60 that penetrate the connecting wall panel 50 in the wall thickness direction.

[0053] In this manner, in this embodiment, the first wooden wall board 30 and the second wooden wall board 40 adjacent in the wall width direction are connected via the connecting wall board 50. Therefore, for example, by adjusting the connection positions of the first wooden wall board 30 and the second wooden wall board 40 and the connecting wall board 50, it is possible to eliminate or reduce the gap between the pair of columns 12 and the first wooden wall board 30 and the second wooden wall board 40. Therefore, rattling of the board wall 20 during an earthquake is suppressed, and a decrease in the initial rigidity of the board wall 20 is suppressed.

[0054] In addition, after arranging a plurality of first wooden wall boards 30 and second wooden wall boards 40 between a pair of columns 12, these first wooden wall boards 30 and second wooden wall boards 40 are connected via the connecting wall boards 50, so that the board wall 20 can be easily installed between the pair of columns 12. Therefore, the workability of the board wall 20 is improved.

[0055] In this manner, in this embodiment, it is possible to improve workability while suppressing a decrease in the initial rigidity of the board wall 20.

[0056] In addition, in this embodiment, the first wooden wall board 30 and the second wooden wall board 40 can be disposed between the pair of columns 12 from the out-of-plane direction of the frame 10. Therefore, the workability of the board wall 20 is further improved.

[0057] Furthermore, the one end sides 30A, 40A of the adjacent first wooden wall board 30 and second wooden wall board 40 are configured as a notched joint that sandwiches the connecting wall board 50 from both sides in the wall thickness direction. As a result, the one end sides 30A, 40A of the adjacent first wooden wall board 30 and second wooden wall board 40 cover and conceal the connecting wall board 50. This improves the design of the board wall 20.

[0058] In addition, the first wooden wall board 30 and the second wooden wall board 40 adjacent to each other in the width direction of the plank wall 20 are arranged across the side surfaces 12S of the pair of columns 12. That is, in this embodiment, the other ends 30E, 40E of the first wooden wall board 30 and the second wooden wall board 40 are in contact with the side surfaces 12S of the pair of columns 12, respectively. This further suppresses the rattling of the plank wall 20 during an earthquake. Therefore, the decrease in the initial rigidity of the plank wall 20 is further suppressed.

[0059] (Modification) Next, a modification of the above embodiment will be described.

[0060] In the above embodiment, the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 are configured as half-slit joints that sandwich the connecting wall board 50 from both sides. However, the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 are not limited to the above half-slit joints.

[0061] 5, one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40 may be arranged on one side of the connecting wall board 50, with the end faces of the one end sides 30A, 40A facing each other. This makes it possible to install the first wooden wall board 30 and the second wooden wall board 40 on the connecting wall board 50 from one side, for example, improving workability.

[0062] In the above embodiment, the other ends 30E, 40E of the first wooden wall board 30 and the second wooden wall board 40 are inserted into the grooves 14 formed in the side surfaces 12S of the pair of columns 12. However, for example, as in a modified example shown in Fig. 6, the other ends 30E, 40E of the first wooden wall board 30 and the second wooden wall board 40 may be brought into contact with the side surfaces 12S of the pair of columns 12 without forming grooves in the side surfaces 12S. In this case, for example, a pair of holding members 70 are provided on the side surfaces 12S of the pair of columns 12 to sandwich the other ends 30E, 40E of the first wooden wall board 30 and the second wooden wall board 40 from both sides.

[0063] In the above embodiment, the connection holes 34, 44, 54 are formed in advance in the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40, and in the connecting wall board 50. However, for example, after the first wooden wall board 30, the second wooden wall board 40, and the connecting wall board 50 are arranged between a pair of columns 12, the connection holes 34, 44, 54 may be formed on-site in the one end sides 30A, 40A of the first wooden wall board 30 and the second wooden wall board 40, and in the connecting wall board 50. This makes it possible to more reliably eliminate gaps between the pair of columns 12 and the other ends 30E, 40E of the first wooden wall board 30 and the second wooden wall board 40.

[0064] Also, in the above embodiment, the connecting hole 34 penetrates the one end 30A of the first wooden wallboard 30. However, the connecting hole 34 may be a bottomed hole without penetrating the one end 30A of the first wooden wallboard 30. Similarly, in the above embodiment, the connecting hole 44 penetrates the one end 40A of the second wooden wallboard 40. However, the connecting hole 44 may be a bottomed hole without penetrating the one end 40A of the second wooden wallboard 40.

[0065] In the above embodiment, the connecting member connecting the one end sides 30A, 40A of the first and second wooden wall boards 30, 40 and the connecting wall board 50 is the connecting pin 60. However, the connecting member is not limited to the connecting pin 60 and may be, for example, a screw member such as a screw screwed into the one end sides 30A, 40A of the first and second wooden wall boards 30, 40 and the connecting wall board 50. In this case, the connecting holes 34, 44, 54 of the one end sides 30A, 40A of the first and second wooden wall boards 30, 40 and the connecting wall board 50 can be omitted, so that the manufacturability of the first wooden wall board 30, the second wooden wall board 40 and the connecting wall board 50 is improved.

[0066] 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.
