(First embodiment)
Hereinafter, a first embodiment of an orthogonal assembly plate and a junction structure for joining orthogonal assembly plates of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of the structure of a wall 1 of a building formed by joining orthogonal laminated plates of the present invention. As shown in FIG. 1, the wall 1 is composed of orthogonal laminated plates 10, 20, and 30 that stand on a floor 2. The orthogonal assembly plates 10, 20, and 30 are joined in a plane or orthogonally. In FIG. 1, the wall 1 and the orthogonal assembly plates 10, 20, and 30 are simplified schematic views. Next, the orthogonal laminated plates 10, 20, and 30 constituting the wall 1 will be described.

  Initially, the orthogonal laminated board 10 is demonstrated using FIG. As shown in FIG. 2, the orthogonal laminated board 10 is a surface material (panel) in which the five layers 11-15 are laminated | stacked. The orthogonal assembly board 10 has a rectangular shape as a whole. Layers 11-15 are bonded between the stacks.

  In the following, the layers 11 and 12 disposed on both outer sides in the stacking direction of the layers 11 to 15 are referred to as “outer layers 11 and 12”, and the layers 13 to 15 disposed on the inner sides of the outer layers 11 and 12 are referred to as “inner layers 13”. ~ 15 ". Further, one of the outer layers 11 and 12 (the one disposed on the upper side in FIG. 2A) is the first outer layer 11, and the other (the one disposed on the lower side in FIG. 2A) is the second outer layer 12. And Further, among the inner layers 13 to 15, the layer 13 bonded to the first outer layer 11 is referred to as “first inner layer 13”, the layer 14 bonded to the first inner layer 13 is referred to as “second inner layer 14”, The layer 15 bonded to the outer layer 12 is referred to as a “third inner layer 15”. In the following, for convenience, the vertical and horizontal directions are set in accordance with the vertical and horizontal directions shown in FIG.

  The first outer layer 11 has a rectangular shape as a whole. The long side direction length of the first outer layer 11 is 3000 mm, the short side direction length is 1000 mm, and the thickness is 30 mm. The first outer layer 11 is composed of five laminas 111. The five laminas 111 are formed in a rectangular shape (strip shape) having the same dimensions. The five laminas 111 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The five laminas 111 are made of cedar ground plates. And the longitudinal direction of the lamina 111 corresponds to the fiber direction of a board. Each lamina 111 is formed to have a length of 3000 mm, a width of 200 mm, and a thickness of 30 mm.

  The overall shape and dimensions of the second outer layer 12 are the same as those of the first outer layer 11. The second outer layer 12 is also composed of five laminas 121. The shape, size, and material of the five laminas 121 are the same as those of the lamina 111. And like the 1st outer layer 11, in the 2nd outer layer 12, five lamina 121 are arranged in the width direction in the state where the both ends of the longitudinal direction were aligned, and predetermined adhesive (for example, for woodworking) Adhesive). The fiber direction of the lamina 121 is parallel to the fiber direction of the lamina 111.

  The overall shape and dimensions of the second inner layer 14 are also the same as those of the first outer layer 11. The second inner layer 14 is also composed of five laminas 141. The shape, size, and material of the five laminas 141 are the same as those of the lamina 111. Similarly to the first outer layer 11, in the second inner layer 14, five laminas 141 are arranged with no gaps in the width direction with both ends in the longitudinal direction aligned, and a predetermined adhesive (for example, woodworking) Adhesive). The fiber direction of the lamina 141 is parallel to the fiber direction of the lamina 111 and the lamina 121.

  The overall shape and dimensions of the first inner layer 13 are also the same as those of the first outer layer 11. However, the first inner layer 13 is composed of 15 laminas 131. Fifteen laminas 131 are formed in a rectangular shape (strip shape) having the same dimensions. The fifteen laminas 131 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The fifteen laminas 131 are made of cedar ground plates. And the longitudinal direction of the lamina 131 corresponds to the fiber direction of the board. Each lamina 131 is formed to have a length of 1000 mm, a width of 200 mm, and a thickness of 30 mm. The fiber direction of the lamina 131 is orthogonal to the fiber directions of the lamina 111, the lamina 121, and the lamina 141.

  The overall shape and dimensions of the third inner layer 15 are the same as those of the first inner layer 13. The third inner layer 15 is also composed of 15 laminaes 151. The shape, size, and material of the 15 lamina 151 are the same as those of the lamina 131. Similarly to the first inner layer 13, in the third inner layer 15, 15 laminas 151 are arranged in the width direction without gaps in a state where both ends in the longitudinal direction are aligned, and a predetermined adhesive (for example, woodworking) Adhesive). The fiber direction of the lamina 151 is parallel to the fiber direction of the lamina 131 and is orthogonal to the fiber directions of the lamina 111, the lamina 121, and the lamina 141.

  By the way, as described above, each of the layers 11 to 15 has a rectangular shape with the same dimensions as a whole. And the layers 11-15 are laminated | stacked in the state in which the both ends of the long side direction are aligned, but the both ends of the short side direction are not aligned. Specifically, both ends in the short side direction of the first outer layer 11 and the second outer layer 12 are aligned, and both ends in the short side direction of the first inner layer 13, the second inner layer 14, and the third inner layer 15 are aligned. Both ends in the short side direction of 11 and 12 and both ends in the short side direction of the inner layers 13 to 15 are not aligned. In other words, the inner layers 13 to 15 are displaced from the outer layers 11 and 12 along the short side direction (the left-right direction in FIGS. 2A and 2C). Therefore, one end of the inner layers 13 to 15 in the short side direction (the right end in FIGS. 2A and 2C) is outside the one end of the outer layers 11 and 12 in the short side direction. The other end portion in the short side direction of the inner layers 13 to 15 (the left end portion in FIGS. 2A and 2C) is more than the other end portion in the short side direction of the outer layers 11 and 12. It is depressed on the center side. As a result, one end in the short side direction of the inner layers 13 to 15 is located outside one end in the short side direction of the outer layers 11 and 12 at one end in the short side direction of the orthogonal laminated plate 10. A projecting portion 16 is formed which is formed of a protruding portion. On the other hand, the other end in the short side direction of the inner layers 13 to 15 is located at the center side of the other end in the short side direction of the outer layers 11 and 12 at the other end in the short side direction of the orthogonal laminated plate 10. A recessed portion 17 made of a depressed portion is formed.

  The convex portion 16 and the concave portion 17 have the same rectangular cross section along the long side direction of the layers 11 to 15, respectively. In FIG. 2, the inner layers 13 to 15 are shifted from the outer layers 11 and 12 by half the width of the lamina 111. That is, the height of the convex portion 16 and the depth of the concave portion 17 (the length in the left-right direction in FIG. 2C) are 100 mm. Further, the width of the convex portion 16 and the width of the concave portion 17 (vertical length in FIG. 2C) correspond to the overall thickness of the inner layers 13 to 15 and are 90 mm.

  Next, the orthogonal assembly board 20 is demonstrated using FIG. As shown in FIG. 3, the orthogonal assembly plate 20 is a face material (panel) in which five layers 21 to 25 are laminated. The orthogonal assembly board 20 has a rectangular shape as a whole. Layers 21-25 are bonded between the stacks.

  In the following, the layers 21 and 22 disposed on both outer sides in the stacking direction of the layers 21 to 25 are referred to as “outer layers 21 and 22”, and the layers 23 to 25 disposed on the inner side of the outer layers 21 and 22 are referred to as “inner layers 23”. ~ 25 ". Also, one of the outer layers 21 and 22 (the one disposed on the upper side in FIG. 3A) is the first outer layer 21, and the other (the one disposed on the lower side in FIG. 3A) is the second outer layer 22. And Further, among the inner layers 23 to 25, the layer 23 bonded to the first outer layer 21 is referred to as a “first inner layer 23”, the layer 24 bonded to the first inner layer 23 is referred to as a “second inner layer 24”, The layer 25 bonded to the outer layer 22 is referred to as a “third inner layer 25”. In the following, for convenience, the vertical and horizontal directions are set in accordance with the vertical and horizontal directions shown in FIG.

  Since the overall shape and dimensions of the first outer layer 21 and the second outer layer 22 are the same as those of the first outer layer 11 of the orthogonal laminated plate 10 and the like, description thereof will be omitted. Further, since the structures of the first outer layer 21 and the second outer layer 22 including the number of laminas 211 and 221 constituting the first outer layer 21 and the second outer layer 22 and the arrangement thereof are the same as those of the first outer layer 11 and the like. Description is omitted. Furthermore, since the shape, dimension, and material of the laminaes 211 and 221 constituting the first outer layer 21 and the second outer layer 22 are the same as those of the lamina 111 and the like, description thereof will be omitted.

  The second inner layer 24 has a rectangular shape as a whole. The long side direction length of the second inner layer 24 is 3000 mm, the short side direction length is 800 mm, and the thickness is 30 mm. The second inner layer 24 is composed of four laminaes 241. The four laminaes 241 are each formed into a rectangular shape (strip shape) having the same dimensions. The four laminaes 241 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The four laminaes 241 are made of cedar ground plates. And the longitudinal direction of the lamina 241 corresponds to the fiber direction of the ground plate. Each lamina 241 has a length of 3000 mm, a width of 200 mm, and a thickness of 30 mm. The fiber direction of the lamina 241 is parallel to the fiber directions of the lamina 211 and the lamina 221.

  The overall shape and dimensions of the first inner layer 23 are the same as those of the second inner layer 24. However, the first inner layer 23 is composed of 15 laminaes 231. The 15 laminaes 231 are formed in a rectangular shape (strip shape) having the same dimensions. The fifteen laminaes 231 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The 15 laminaes 231 are made of cedar ground plates. And the longitudinal direction of the lamina 231 corresponds to the fiber direction of the board. Each lamina 231 has a length of 800 mm, a width of 200 mm, and a thickness of 30 mm. The fiber direction of the lamina 231 is orthogonal to the fiber directions of the lamina 211, the lamina 221, and the lamina 241.

  The overall shape and dimensions of the third inner layer 25 are the same as those of the first inner layer 23. The third inner layer 25 is also composed of 15 laminaes 251. The shape, size, and material of the 15 laminaes 251 are the same as those of the lamina 231. Similarly to the first inner layer 23, in the third inner layer 25, fifteen laminaes 251 are arranged with no gaps in the width direction with both ends in the longitudinal direction aligned, and a predetermined adhesive (for example, woodworking) Adhesive).

  By the way, as described above, the overall shape of the outer layers 21 and 22 and the overall shape of the inner layers 23 to 25 are both rectangular, but their dimensions are different. Specifically, the short side lengths of the outer layers 21 and 22 are longer than the short side lengths of the inner layers 23 to 25. And both ends of the long side direction of the outer layers 21 and 22 and both ends of the long side direction of the inner layers 23 to 25 are aligned, but both ends of the short side direction of the outer layers 21 and 22 and the short sides of the inner layers 23 to 25 are aligned. It is not aligned with both ends of the direction. Specifically, both ends of the inner layers 23 to 25 in the short side direction are closer to the center side in the short side direction than both ends of the outer layers 21 and 22 in the short side direction. That is, both end portions in the short side direction of the inner layers 23 to 25 are depressed more toward the center than both end portions in the short side direction of the outer layers 21 and 22. As a result, at both ends in the short side direction of the orthogonal assembly plate 20, two end portions in the short side direction of the inner layers 23 to 25 are formed inwardly from the both end portions in the short side direction of the outer layers 21 and 22. Recesses 26 and 27 are formed. The recesses 26 and 27 have the same rectangular cross section along the long side direction of the layers 21 to 25, respectively. In FIG. 3, both ends of the inner layers 23 to 25 in the short side direction are the same distance from the both ends in the short side direction of the outer layers 21 and 22 toward the center, specifically, half the width of the lamina 211. That is, the depth of the recesses 26 and 27 (the length in the left-right direction in FIG. 3C) is 100 mm. Further, the width of the recesses 26 and 27 (length in the vertical direction in FIG. 3C) corresponds to the overall thickness of the inner layers 23 to 25, and is 90 mm.

  Next, the orthogonal assembly board 30 is demonstrated using FIG. As shown in FIG. 4, the orthogonal assembly plate 30 is a face material (panel) in which five layers 31 to 35 are laminated. The orthogonal assembly plate 30 has a rectangular shape as a whole. Layers 31-35 are bonded between the stacks.

  In the following, the layers 31 and 32 disposed on both outer sides in the stacking direction of the layers 31 to 35 are referred to as “outer layers 31 and 32”, and the layers 33 to 35 disposed on the inner side of the outer layers 31 and 32 are referred to as “inner layers 33”. ~ 35 ". One of the outer layers 31 and 32 (the one disposed on the upper side in FIG. 4A) is the first outer layer 31, and the other (the one disposed on the lower side in FIG. 4A) is the second outer layer 32. And Further, among the inner layers 33 to 35, the layer 33 bonded to the first outer layer 31 is referred to as a “first inner layer 33”, the layer 34 bonded to the first inner layer 33 is referred to as a “second inner layer 34”, The layer 35 bonded to the outer layer 32 is referred to as a “third inner layer 35”. In the following, for convenience, the vertical and horizontal directions are set in accordance with the vertical and horizontal directions shown in FIG.

  Since the overall shape and dimensions of the first outer layer 31 are the same as those of the first outer layer 11, description thereof is omitted. Further, since the structure of the first outer layer 31 including the number of laminas 311 constituting the first outer layer 31 and the arrangement thereof is the same as that of the first outer layer 11, description thereof is omitted. Furthermore, since the shape, dimensions, and material of the lamina 311 constituting the first outer layer 31 are the same as those of the lamina 111, the description thereof is omitted.

  Since the overall shape and dimensions of the inner layers 33 to 35 are the same as those of the inner layers 13 to 15, description thereof is omitted. Further, the structure of the inner layers 33 to 35 including the number and arrangement of the laminas 331, 341, and 351 constituting the inner layers 33 to 35 is the same as that of the inner layers 13 to 15, and therefore, the description thereof is omitted. Furthermore, since the shapes, dimensions, and materials of 331, 341, and 351 constituting the inner layers 33 to 35 are the same as those of the laminas 131, 141, and 151, description thereof is omitted.

  The second outer layer 32 has a rectangular shape as a whole. The long side direction length of the second outer layer 32 is 3000 mm, the short side direction length is 1045 mm, and the thickness is 30 mm. The second outer layer 32 includes four first laminaes 321 and one second lamina 322. The four first laminaes 321 are each formed into a rectangular shape (strip shape) having the same dimensions. Each first lamina 321 has a length of 3000 mm, a width of 200 mm, and a thickness of 30 mm. The second lamina 322 has a length of 3000 mm, a width of 245 mm, and a thickness of 30 mm. The four first laminaes 321 and the one second lamina 322 are made of cedar ground plates. And the longitudinal direction of the 1st lamina 321 and the 2nd lamina 322 corresponds with the fiber direction of a board. Four first laminaes 321 and one second lamina 322 are aligned with no gaps in the width direction with both ends in the longitudinal direction aligned, and bonded with a predetermined adhesive (for example, an adhesive for woodworking) Has been. In FIG. 4, the second lamina 322 is disposed at the end of one side (left side in FIGS. 4A and 4C) in the short side direction of the second outer layer 32.

  Incidentally, as described above, the overall shape of the first outer layer 31 and the overall shape of the second outer layer 32 are both rectangular, but their dimensions are different. Specifically, the length in the short side direction of the second outer layer 32 is 45 mm longer than the length in the short side direction of the first outer layer 31. In the orthogonal assembly plate 30, both ends of the first outer layer 31 in the long side direction and one end in the short side direction (the right end in FIGS. 4A and 4C) and the long side direction of the second outer layer 32. Although both ends and one end in the short side direction are aligned, the other end in the short side direction of the first outer layer 31 (the left end in FIGS. 4A and 4C) and the short side direction of the second outer layer 32 Is not aligned with the other end. In other words, the other end in the short side direction of the second outer layer 32 is 45 mm outward in the short side direction from the other end in the short side direction of the first outer layer 31, that is, the overall thickness of the inner layers 33 to 35. Half of it is protruding.

  The layers 31 to 35 are stacked in a state where both ends in the long side direction are aligned but both ends in the short side direction are not aligned. Specifically, both ends in the short side direction of the outer layers 31 and 32 are not aligned with both ends in the short side direction of the inner layers 33 to 35. The inner layers 33 to 35 protrude from the end in the short side direction on the side where the outer layers 31 and 32 are aligned (the right side in FIGS. 4A and 4C). Further, the inner layers 33 to 35 are closer to the center side than the ends in the short side direction on the side where the outer layers 31 and 32 are not aligned (the left side in FIGS. 4A and 4C). As a result, one end portion in the short side direction of the inner layers 33 to 35 is formed at one end portion in the short side direction of the orthogonal assembly plate 30 (the right end portion in FIGS. 4A and 4C). A convex portion 36 is formed, which is a portion projecting outward from one end portion in the short side direction of the outer layers 31 and 32. On the other hand, at the other end portion in the short side direction of the orthogonal assembly plate 30, the other end portion in the short side direction of the inner layers 33 to 35 is closer to the center side than the other end portion in the short side direction of the outer layers 31 and 32. A recessed portion 37 made of a depressed portion is formed. The convex portion 36 and the concave portion 37 have the same cross-sectional shape along the long side direction of the layers 31 to 35, respectively. In FIG. 4, the inner layers 33 to 35 are half the width of the lamina 311 from the end in the short side direction on the side where the outer layers 31 and 32 are aligned (the right side in FIGS. 4A and 4C). , Protruding. That is, the height of the convex portion 36 (the length in the left-right direction in FIG. 4C) is 100 mm. Further, the depth of the shallower side of the concave portion 37 (first outer layer 31 side) is 100 mm, and the depth of the deeper side (second outer layer 32 side) is 145 mm. Further, the width of the convex portion 36 and the width of the concave portion 37 (the length in the vertical direction in FIG. 4C) correspond to the overall thickness of the inner layers 33 to 35, and are 90 mm.

  As described above, the orthogonal assembly plate 10 has the convex portion 16 and the concave portion 17. Further, the orthogonal assembly plate 20 has recesses 26 and 27. Further, the orthogonal assembly plate 30 has a convex portion 36 and a concave portion 37. The widths of the convex portions 16 and 36 are the same as the widths of the concave portions 17, 26, 27 and 37. Further, the height of the convex portions 16, 36, the depth of the concave portions 17, 26, 27 and the depth of the shallower concave portion 37 are the same. Here, a joining structure and a method for joining the orthogonal assembled plates 10, 20, and 30 using the convex portions 16 and 36 and the concave portions 17, 26, 27, and 37 will be described.

  First, a structure for joining the orthogonal assembly plate 10 and the orthogonal assembly plate 10 in a planar manner and a joining method thereof will be described. In the following description, a structure that is planarly bonded is also referred to as a “planar bonded structure”. As described above, the width of the convex portion 16 and the width of the concave portion 17 are the same, and the height of the convex portion 16 and the depth of the concave portion 17 are also the same. Therefore, the convex part 16 and the recessed part 17 can be fitted.

  As shown in FIG. 5A, the two orthogonal assembled plates 10 and 10 are arranged apart in the short side direction with both ends in the long side direction aligned. At this time, the convex part 16 of one orthogonal assembly board 10 and the recessed part 17 of the other orthogonal assembly board 10 oppose along a short side direction. Here, a predetermined adhesive (for example, an adhesive for woodworking) is applied to the outer surface of the opposing convex portion 16 and the inner surface of the concave portion 17 (not shown). Then, as shown in FIG. 5 (B), the two orthogonal assembly plates 10 and 10 are flat with the convex portions 16 and the concave portions 17 by fitting the opposing convex portions 16 and the concave portions 17 and curing them. And are firmly integrated.

  Next, a structure for planarly joining the orthogonal assembly plate 10 and the orthogonal assembly plate 20 (planar joint structure of the orthogonal assembly plate 10 and the orthogonal assembly plate 20) and a joining method thereof will be described. As described above, the width of the convex portion 16 and the width of the concave portions 26 and 27 are the same, and the height of the convex portion 16 and the depth of the concave portions 26 and 27 are also the same. Therefore, the convex part 16 and the recessed parts 26 and 27 can be fitted.

  As shown in FIG. 6A, the orthogonal assembly plate 10 and the orthogonal assembly plate 20 are arranged apart in the short side direction with both ends in the long side direction aligned. At this time, the convex part 16 of the orthogonal assembly board 10 and the recessed part 27 of the orthogonal assembly board 20, for example, face each other along the short side direction. Here, a predetermined adhesive (for example, an adhesive for woodworking) is applied to the outer surface of the convex portion 16 and the inner surface of the concave portion 27 (not shown). Then, as shown in FIG. 6 (B), by fitting the opposing convex portion 16 and the concave portion 27 together and curing, the orthogonal assembled plate 10 and the orthogonal assembled plate 20 are formed by the convex portion 16 and the concave portion 27. It is joined flatly and firmly integrated.

  Next, a joining structure and joining method in which one orthogonal assembly plate 10 and two orthogonal assembly plates 30 are joined in a T-shape (an orthogonal three-pronged structure) will be described. As described above, the end of the second outer layer 32 of the orthogonal laminated plate 30 on the side where the second lamina 322 is disposed is shorter than the end of the first outer layer 31, so that the entire inner layers 33 to 35 are arranged. Half the thickness, protruding outward.

  Therefore, as shown in FIG. 7A, the two orthogonal laminated plates 30 are arranged such that the respective second laminas 322 are connected along the short side direction of the second outer layer 32. FIG. 7A is a plan view, and the orthogonal assembly plate 30 stands on the floor 2 so that the long side direction of the two orthogonal assembly plates 30 is orthogonal to the floor 2. Further, the orthogonal assembly plate 10 is made to stand on the floor 2 so that the long side direction of the orthogonal assembly plate 10 is orthogonal to the floor 2. Then, the end portion of the first outer layer 11 on the side where the concave portion 17 of the orthogonal assembly plate 10 is formed is applied to the end portion of the first outer layer 31 on the side where the concave portion 37 of the one orthogonal assembly plate 30 is formed. The end of the second outer layer 12 on the side where the recess 17 of the orthogonal assembly plate 10 is formed is connected to the end of the first outer layer 31 on the side where the recess 37 of the other orthogonal assembly plate 30 is formed. Make contact. Then, the recess 17 of the orthogonal assembly plate 10 and the recess 37 of the two orthogonal assembly plates 30 communicate with each other, in other words, along the inner surface of the recess 17 of the orthogonal assembly plate 10 and the inner surface of the recess 37 of the orthogonal assembly plate 30. Thus, a T-shaped gap 1737 is formed.

  Next, as shown in FIG. 7B, in the gap 1737, a reinforcing bar 18 made of, for example, round steel or a deformed reinforcing bar is installed in parallel with the long side direction of the orthogonal laminated plates 10 and 30. Subsequently, as shown in FIG. 7C, concrete 19 is placed in the gap 1737 in which the reinforcing bars 18 are disposed. Then, as shown in FIG. 7 (D), the concrete 19 is filled in the gap portion 1737 and cured, so that the orthogonal laminated plate 10 and the two orthogonal laminated plates 30 are joined in a T shape with the concrete 19. At the same time, the pillar 3 made of the reinforcing bar 18 and the concrete 19 is formed inside the joined orthogonal assembly plate 10 and the two orthogonal assembly plates 30.

  As described above, the adhesive is applied to the convex portion 16 formed at one end portion in the short side direction of the orthogonal assembly plate 10 and the concave portion 17 formed at the other end portion in the short side direction of the orthogonal assembly plate 10. Can be joined to each other by planar bonding. Both the convex portion 16 and the concave portion 17 are formed in the central portion of the orthogonal assembled plate 10 in the stacking direction, and the joint portion is hidden inside. Therefore, the joint portion can be simplified and the design of the joint portion can be improved. Further, it is possible to reduce the number of parts necessary for the planar joining and to save labor.

  Note that the planar joint structure between the orthogonal assembly plate 10 and the orthogonal assembly plate 20 shown in FIG. 6 also has the same effect as the planar connection structure between the orthogonal assembly plates 10. Further, since the height and width of the convex portion 36 formed on the orthogonal assembly plate 30 is the same as that of the convex portion 16, the orthogonal assembly plate 30 is used instead of the orthogonal assembly plate 10 of FIGS. 5 and 6. The orthogonal assembly plate 30 and the orthogonal assembly plates 10 and 20 can be joined in a planar manner by fitting and bonding the convex portion 36 and the concave portions 17, 26 and 27.

  Further, in the orthogonal laminated plate 10, the overall shape and dimensions of all the layers 11 to 15 are the same, and the convex portions are formed by relatively shifting the short side direction positions of the outer layers 11 and 12 and the inner layers 13 to 15. Since 16 and the recessed part 17 are formed, manufacture of the orthogonal laminated board 10 including the convex part 16 and the recessed part 17 can be facilitated. Here, the outer layers 11 and 12 and the inner layers 13 to 15 have the same length in the short side direction, but the outer layers 11 and 12 and the inner layers 13 to 15 are manufactured so that the lengths in the short side direction are different. The convex portions 16 and the concave portions 17 may be formed by disposing 11 and 12 and the inner layers 13 to 15 so as to be shifted in the short side direction. In this case, the height of the convex portion 16 and the depth of the concave portion 17 are different. Furthermore, in the orthogonal laminated board 20, since the short side direction length of the inner layers 23-25 is shorter than the short side direction length of the outer layers 21 and 22, the weight reduction of the orthogonal laminated board 20 whole can be achieved.

  Moreover, the concrete 19 which has adhesiveness is attached to the T-shaped space | gap part 1737 formed by the recessed part 17 formed in the orthogonal laminated board 10 and the recessed part 37 formed in the orthogonal laminated board 30 communicating. By filling, the orthogonal assembly plate 10 and the two orthogonal assembly plates 30 can be joined in a T-shape and firmly integrated. Here, since the concrete 19 is covered with the outer layers 11, 12, 31, and 32 and is hidden inside, the joint portion can be simplified and the design of the joint portion can be improved. Further, it is possible to reduce the number of parts necessary for the planar joining and to save labor. In addition, the outer layers 11, 12, 31, and 32 that define the gap 1737 function as a formwork for placing the concrete 19, and can be used as part of the wall 1 as it is. It is possible to suppress the operation and improve the work efficiency. Moreover, since the pillar 3 containing the concrete 19 and the reinforcing bar 18 which have rigidity higher than wood is solidified after solidifying, joining the orthogonal laminated board 10 and the orthogonal laminated board 30, it raises the intensity | strength of a building effectively. be able to. In addition, since the concrete 19 before solidification has fluidity, the concrete 19 can be filled according to the shape of the gap portion 1737 regardless of the arrangement accuracy or manufacturing error of the orthogonal laminated plate 10 or the orthogonal laminated plate 30. .

  In addition, since the depth and width of the recesses 26 and 27 formed in the orthogonal assembly plate 20 are the same as those of the recess 17, the orthogonal assembly plate 20 is used instead of the orthogonal assembly plate 10 in FIG. The plate 20 and the two orthogonal assembly plates 30 can be joined in a T-shape.

  Next, the joining structure and joining method for constructing the wall and floor of a building using the orthogonal laminated board of this invention are demonstrated. Here, the walls and floor of the building are constructed by joining the orthogonal laminated plates 40 and 50 together.

  First, the orthogonal assembly plate 40 will be described with reference to FIG. As shown in FIG. 8, the orthogonal assembly plate 40 is a face material (panel) in which five layers 41 to 45 are laminated. The orthogonal assembly plate 40 has a rectangular shape as a whole. Layers 41-45 are bonded between the stacks. Each layer 41 to 45 includes a plurality of laminas 411, 421, 431, 441, and 451.

  In the following, the layers 41 and 42 disposed on both outer sides in the stacking direction of the layers 41 to 45 are referred to as “outer layers 41 and 42”, and the layers 43 to 45 disposed on the inner sides of the outer layers 41 and 42 are referred to as “inner layers 43”. ~ 45 ". One of the outer layers 41 and 42 (the one disposed on the upper side in FIG. 8A) is the first outer layer 41, and the other (the one disposed on the lower side in FIG. 8A) is the second outer layer 42. And Further, among the inner layers 43 to 45, the layer 43 bonded to the first outer layer 41 is referred to as a “first inner layer 43”, the layer 44 bonded to the first inner layer 43 is referred to as a “second inner layer 44”, and The layer 45 bonded to the outer layer 42 is referred to as a “third inner layer 45”.

  The first outer layer 41 has a rectangular shape as a whole. The long side direction length of the first outer layer 41 is 3000 mm, the short side direction length is 1000 mm, and the thickness is 30 mm. The first outer layer 41 is composed of five laminas 411. The five laminas 411 are formed in a rectangular shape (strip shape) having the same dimensions. The five laminas 411 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The five laminas 411 are made of cedar ground plates. And the longitudinal direction of the lamina 411 corresponds with the fiber direction of a board. Each lamina 411 has a length of 3000 mm, a width of 200 mm, and a thickness of 30 mm.

  The overall shape and dimensions of the second outer layer 42 are the same as those of the first outer layer 41. The second outer layer 42 is also composed of five laminaes 421. The shape, size, and material of the five laminaes 421 are the same as those of the lamina 411. And like the 1st outer layer 41, in the 2nd outer layer 42, five sheets of lamina 421 are arranged in the width direction without gap in the state where both ends of the longitudinal direction were aligned, for example, predetermined adhesive (for example, for woodworking) Adhesive). The fiber direction of the lamina 421 is parallel to the fiber direction of the lamina 411.

  The second inner layer 44 has a rectangular shape as a whole. The long side direction length of the second inner layer 44 is 2800 mm, the short side direction length is 1000 mm, and the thickness is 30 mm. The second inner layer 44 is also composed of five laminaes 441. The five laminaes 441 are each formed into a rectangular shape (strip shape) having the same dimensions. The five laminaes 441 are bonded together with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The five laminas 441 are made of cedar ground plates. And the longitudinal direction of the lamina 441 corresponds with the fiber direction of a board. Each lamina 441 is formed to have a length of 2800 mm, a width of 200 mm, and a thickness of 30 mm. The fiber direction of the lamina 441 is parallel to the fiber direction of the lamina 411 and the lamina 421.

  The overall shape and dimensions of the first inner layer 43 are the same as those of the second inner layer 44. However, the first inner layer 43 is composed of 14 laminaes 431. Fourteen laminas 431 are formed in a rectangular shape (strip shape) having the same dimensions. The fourteen laminas 431 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. Fourteen laminas 431 are made of cedar ground plates. And the longitudinal direction of the lamina 431 corresponds with the fiber direction of a board. Each lamina 431 is formed to have a length of 1000 mm, a width of 200 mm, and a thickness of 30 mm. The fiber direction of the lamina 431 is orthogonal to the fiber directions of the lamina 411, the lamina 421, and the lamina 441.

  The overall shape and dimensions of the third inner layer 45 are the same as those of the first inner layer 43. The third inner layer 45 is also composed of 14 laminaes 451. The fourteen laminas 451 have the same shape, dimensions, and materials as the lamina 431. Similarly to the first inner layer 43, in the third inner layer 45, 14 laminas 451 are arranged without gaps in the width direction with both ends in the longitudinal direction aligned, and a predetermined adhesive (for example, woodworking) Adhesive). The fiber direction of the lamina 451 is parallel to the fiber direction of the lamina 431, and is orthogonal to the fiber directions of the lamina 411, lamina 421, and lamina 441.

  As described above, the layers 41 to 45 including the laminas 411, 421, 431, 441, and 451 are laminated to form the orthogonal assembly plate 40. And in the orthogonal assembly board 40, each layer 41-45 is laminated | stacked and bonded in the state which the fiber direction of the board aligned in parallel by the layers 41-45 orthogonally crossed along the lamination direction.

  By the way, as described above, the overall shape of the outer layers 41 and 42 and the overall shape of the inner layers 43 to 45 are both rectangular, but their dimensions are different. Specifically, the short side direction length of the outer layers 41 and 42 is the same as the short side direction length of the inner layers 43 to 45, but the long side direction length of the outer layers 41 and 42 is the long side of the inner layers 43 to 45. Longer than the direction length. And although the both ends of the short side direction of each layer 41-45 and the end of the one side of a long side direction are aligning, the end of the other side of a long side direction is not aligning. Specifically, one end in the long side direction of the outer layers 41 and 42 and one end in the long side direction of the inner layers 42 to 44 are aligned, but the other end in the long side direction of the outer layers 41 and 42 is aligned. The end on the side and the end on the other side in the long side direction of the inner layers 42 to 44 are not aligned. In other words, the end on the other side in the long side direction of the inner layers 42 to 44 is closer to the center in the long side direction than the end on the other side in the long side direction of the outer layers 41, 42. As a result, the other side end in the long side direction of the inner layers 42 to 44 is more central than the other side end in the long side direction of the outer layers 41, 42 at the end portion on the other side in the long side direction of the orthogonal laminated plate 40. A concave portion 46 is formed which is formed by a depressed portion in the middle of the direction. The recessed part 46 becomes the same cross-sectional rectangular shape along the short side direction of the layers 41-45. In FIG. 8, the end on the other side in the long side direction of the inner layers 42 to 44 is longer than the other end in the long side direction of the outer layers 41 and 42 by the width of the lamina 431 and 451. Close to the center in the side direction. That is, the depth of the recess 46 is 200 mm. Moreover, since the width | variety of the recessed part 46 is corresponded to the whole thickness of the inner layers 42-44, it is 90 mm.

  Next, the orthogonal laminated board 50 is demonstrated using FIG. As shown in FIG. 9, the orthogonal assembly plate 50 is a face material (panel) in which five layers 51 to 55 are laminated. The orthogonal assembly board 50 has a rectangular shape as a whole. Layers 51-55 are adhered between the stacks. Each of the layers 51 to 55 includes a plurality of laminas 511, 521, 531, 541, and 551.

  In the following, the layers 51 and 52 disposed on both outer sides in the stacking direction of the layers 51 to 55 are referred to as “outer layers 51 and 52”, and the layers 53 to 55 disposed on the inner side of the outer layers 51 and 52 are referred to as “inner layers 53”. ~ 55 ". One of the outer layers 51 and 52 (the one disposed on the upper side in FIG. 9) is the first outer layer 51, and the other (the one disposed on the lower side in FIG. 9) is the second outer layer 52. Further, among the inner layers 53 to 55, the layer 53 bonded to the first outer layer 51 is referred to as a “first inner layer 53”, the layer 54 bonded to the first inner layer 53 is referred to as a “second inner layer 54”, The layer 55 bonded to the outer layer 52 is referred to as a “third inner layer 55”.

  The outer layers 51 and 52 have a rectangular shape as a whole. The outer layers 51 and 52 have a long side of 3000 mm, a short side of 1000 mm, and a thickness of 30 mm. The outer layers 51 and 52 are each composed of five laminae 511 and 521. The five laminaes 511 and 521 are formed in a rectangular shape (strip shape) having the same dimensions. The five laminaes 511 and 521 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The five laminaes 511 and 521 are composed of cedar ground plates. And the longitudinal direction of lamina 511,521 corresponds with the fiber direction of a board. The fiber direction of the lamina 511 and the fiber direction of the lamina 521 are parallel. Each lamina 511 and 521 is formed to have a length of 3000 mm, a width of 200 mm, and a thickness of 30 mm.

  The overall shape and dimensions of the inner layers 53, 54 and 55 are the same as those of the outer layers 51 and 52. Of the inner layers 53, 54, and 55, the inner layers 53 and 55 disposed on both outer sides are composed of 15 laminaes 531 and 551. The fifteen laminas 531 and 551 are formed in a rectangular shape (strip shape) having the same dimensions. The 15 laminaes 531 and 551 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The 15 laminaes 531 and 551 are made of cedar ground plates. And the longitudinal direction of 15 lamina 531 and 551 corresponds with the fiber direction of a board. The fiber directions of the 15 laminaes 531, 551 are orthogonal to the fiber directions of the laminaes 511, 521. Each lamina 531 and 551 is formed to have a length of 1000 mm, a width of 200 mm, and a thickness of 30 mm.

  Of the inner layers 53, 54 and 55, the inner layer 54 arranged on the inner side is composed of five laminaes 541. The five laminaes 541 are formed in a rectangular shape (strip shape) having the same dimensions as the laminas 511 and 521. The five laminaes 541 are bonded with a predetermined adhesive (for example, an adhesive for woodworking) in a state where both ends in the longitudinal direction are aligned with no gap in the width direction. The five laminas 541 are made of cedar ground plates. And the longitudinal direction of the five lamina 541 corresponds with the fiber direction of a board. The fiber directions of the five laminaes 541 are parallel to the fiber directions of the laminaes 511 and 521 and are orthogonal to the fiber directions of the laminaes 531 and 551. Each lamina 541 has a length of 3000 mm, a width of 200 mm, and a thickness of 30 mm.

  As described above, the layers 51 to 55 including the laminaes 511, 521, 531, 541, and 551 are laminated to constitute the orthogonal assembly plate 50. And in the orthogonal assembly board 50, each layer 51-55 is laminated | stacked and bonded in the state which the fiber direction of the board aligned in parallel by the layers 51-55 orthogonally crossed along the lamination direction. Moreover, each layer 51-55 is exhibiting the rectangular shape of the same dimension as a whole. And both ends of the long side direction and both ends of the short side direction of each layer 51 to 55 are aligned.

  Next, a T-shaped (orthogonal three-pronged) joining structure in which a wall and a floor are constructed using one orthogonal assembly plate 40 and two orthogonal assembly plates 50 will be described. As described above, one end in the long side direction of the orthogonal assembly plate 40 is aligned, while the other end is not aligned, and the recess 46 is formed.

  Therefore, as shown in FIG. 10A, the orthogonal assembly plate 40 is erected vertically on the floor (not shown) so that the recess 46 is disposed on the upper side (opens upward). Then, the orthogonal assembly plate 50 is mounted on each of the ends of the outer layers 41 and 42 on the side where the concave portions 46 are formed so as to be orthogonal to the orthogonal assembly plate 40, and the two orthogonal assembly plates 50 are disposed along the long side direction. The both ends of the short side direction are aligned with the both ends of the orthogonal assembly plate 40 in the short side direction. At this time, the flat side surfaces of the two orthogonal assembled plates 50 face each other along the long side direction. And the end of the long side direction of the opposite side of the orthogonal assembly board 50 is aligned with the inner end of the contacting outer layers 41 and 42 in the stacking direction. As a result, an opening 56 sandwiched between the two orthogonal assembly plates 50 is formed on the recess 46. The opening 56 and the recess 46 communicate with each other. In other words, an I-shaped gap 4656 is formed along the inner surface of the recess 46 of the orthogonal assembly plate 40 and the flat side surface of the orthogonal assembly plate 50.

  Next, as shown in FIG. 10B, a reinforcing bar 48 made of round steel or a deformed reinforcing bar is appropriately installed in the gap 4656 along the short side direction of the orthogonal laminated plate 40. Subsequently, as shown in FIG. 10C, concrete 49 is placed in the gap 4656 in which the reinforcing bars 48 are arranged. Then, as shown in FIG. 10 (D), the concrete portion 49 is filled with concrete 49 and cured so that one orthogonal laminated plate 40 and two orthogonal laminated plates 50 are T-shaped with the concrete 49. To be joined. As a result, a wall 4 composed of orthogonal assembly plates 40 standing perpendicular to the floor and a floor 5 composed of orthogonal assembly plates 50 held horizontally on the wall 4 are constructed and joined together. A beam 6 made of a reinforcing bar 48 and concrete 49 is formed between the orthogonal assembly plate 40 and the two orthogonal assembly plates 50.

  Thus, the concrete having adhesiveness in the gap 4656 formed by the communication between the recess 46 formed in the orthogonal assembly plate 40 and the opening 56 sandwiched between the two orthogonal assembly plates 50. By filling 49, the orthogonal assembly plate 40 and the two orthogonal assembly plates 50 can be joined in a T-shape and firmly integrated. Here, since the concrete 49 is covered with the outer layers 41 and 42 and the orthogonal laminated plate 50 and hidden inside, the joint portion can be simplified and the design of the joint portion can be improved. Further, it is possible to reduce the number of parts necessary for the planar joining and to save labor. Furthermore, since the portion of the outer layers 41 and 42 that define the gap 4656 and the orthogonal laminated plate 50 function as a formwork for placing the concrete 49 and can be used as part of the wall 4 and the floor 5 as it is, The increase in cost can be suppressed and the work efficiency can be improved. In addition, since the beams 6 including the concrete 49 and the reinforcing bars 48 having higher rigidity than wood after the solidification are constructed while joining the orthogonal assembly plate 40 and the orthogonal assembly plate 50, the strength of the building is effectively increased. be able to. In addition, since the concrete 49 before solidification has fluidity, the concrete 49 can be filled in accordance with the shape of the gap 4656 regardless of the arrangement accuracy or manufacturing error of the orthogonal laminated plate 40 or the orthogonal laminated plate 50. .

  In addition, when constructing the beam 6 by placing the concrete 49, there is no problem even if the upper side is opened. Therefore, as in the case of constructing the column 3 with the orthogonal assembly plate 10 and the orthogonal assembly plate 30, It is not necessary to make the outer layer 32 longer than the other outer layer 31 and close the gap 1737 in the circumferential direction. The end of the orthogonal assembly plate 50 on the side where the opening 56 is not formed is flat, and no protrusions or recesses such as the protrusions 16 and the recesses 17 are formed. A convex portion or a concave portion may be formed.

(Other embodiments)
Next, embodiments of the present invention other than the above-described first embodiment will be described.

  The lamina contained in the orthogonal laminated plates 10, 20, 30, 40, 50 (hereinafter referred to as “orthogonal laminated plate 10”) is composed of cedar, but the wood that constitutes the lamina is not limited to cedar, but cypress Another kind of wood (woody material) such as Japanese larch may be used. Moreover, the orthogonal laminated board 10 etc. do not need to be comprised with one type of wood. For example, the type of wood may be different for each layer or ply constituting the orthogonal laminated plate 10 or the like. Moreover, in the same layer, you may vary the kind of wood for every lamina. Furthermore, although the lamina contained in the orthogonal laminated board 10 etc. is comprised with the board, you may replace a part or all of a lamina with the small square material whose cross-sectional shape is a square or a rectangle.

  Further, the overall shape and dimensions of the orthogonal laminated plate 10 and the like are not limited to the above-described example, and may be appropriately changed. For example, the aspect ratio of the rectangular shape in a plan view such as the orthogonal laminated plate 10 may be changed. Furthermore, you may change the whole thickness of the orthogonal laminated board 10 grade | etc.,.

  In addition, the number, shape, and dimensions of the layers constituting the orthogonal laminated plate 10 and the like are not limited to the above-described example, and may be appropriately changed. For example, the number of layers constituting the orthogonal laminated plate 10 may be more or less than five. Moreover, you may change the aspect ratio of the rectangular shape of planar view of the layer which comprises the orthogonal laminated board 10 grade | etc.,. Furthermore, although the thickness of the layer which comprises the orthogonal laminated board 10 etc. is the same, you may vary thickness by layer. By varying the thickness, the thicknesses of the convex portions 16 and 36 and the concave portions 17, 26, 27, 37, 46 and the opening 56 (hereinafter referred to as “the convex portion 16 and the concave portion 17”) can be adjusted. it can.

  Moreover, although all the layers which comprise the orthogonal laminated board 10 etc. are comprised by one ply, you may comprise by several ply. In other words, a layer may be formed by stacking a plurality of laminaes in the stacking direction.

  Furthermore, the fiber direction of the lamina which comprises the orthogonal laminated board 10 etc. is not restricted to the example mentioned above, You may change suitably. For example, the fiber direction of the lamina constituting the layers 11, 12, 14 and the like is made parallel to the short side direction of the orthogonal laminated plate 10 or the like, and the fiber direction of the lamina constituting the inner layers 13 and 15 or the like is the length of the orthogonal laminated plate 10 or the like. It may be parallel to the side direction.

  In addition, in the orthogonal laminated plate 10 and the like, the fiber directions of the lamina constituting the layers are alternately orthogonal along the stacking direction, but are not necessarily orthogonal. For example, the fiber directions of the lamina constituting a part of the layers continuous in the stacking direction may be parallel. Specifically, in the case of the orthogonal laminated plate 10, the fiber direction of the lamina 141 constituting the layer 14 arranged at the center in the stacking direction is made parallel to the short side direction of the orthogonal laminated plate 10, and the other layers 11, The fiber directions of the laminas 111, 121, 131, 151 constituting the 12, 13, 15 may be parallel to the long side direction of the orthogonal laminated plate 10.

  Moreover, although the center of the width direction, such as the convex part 16 and the recessed part 17, is in agreement with the center of thickness direction, such as the orthogonal laminated board 10, it is not necessary to make it correspond. That is, the center in the width direction such as the convex portion 16 and the concave portion 17 may be decentered with respect to the center in the thickness direction such as the orthogonal laminated plate 10. For example, in the case of the orthogonal laminated plate 10, a layer having the same structure as that of the first outer layer 11 is laminated on the surface of the first outer layer 11, and the orthogonal laminated plate 10 has a six-layer structure. In this case, the center in the thickness direction of the orthogonal laminated plate 10 is a contact surface between the third layer (first inner layer 13) and the fourth layer (second inner layer 14) from the upper side. The center in the width direction is the center in the thickness direction of the fourth layer (second inner layer 14) from the upper side.

  Further, in the case of the orthogonal laminated plate 10, both ends in the short side direction of the third inner layer 15 are matched with both ends in the short side direction of the outer layers 11, 12, and the protruding portion of the protruding portion 16 and the recessed portion 17 are depressed. It is assumed that the portion is composed of the first inner layer 13 and the second inner layer 14. In this case, the center of the orthogonal assembly plate 10 in the thickness direction is the center of the second inner layer 14 in the thickness direction, but the centers of the convex portions 16 and the concave portions 17 in the width direction are the first inner layer 13 and the second inner layer 14. It becomes an adhesive surface.

  Moreover, in the orthogonal laminated board 10, although the height of the convex part 16 formed in one side of a short side direction and the depth of the recessed part 17 formed in the other side of a short side direction are the same, it makes them differ. Also good. Similarly, in the orthogonal assembly plate 20, the depth of the concave portion 26 formed on one side in the short side direction is the same as the depth of the concave portion 27 formed on the other side in the short side direction. Also good. For example, in the case of the orthogonal laminated plate 20, the inner layers 23 to 25 may be shifted to the left side in the short side direction when viewed from the front by 50 mm. In this case, the depth of the concave portion 26 formed on one side in the short side direction of the orthogonal assembly plate 20 is 150 mm, and the depth of the concave portion 27 formed on the other side in the short side direction is 50 mm.

  Further, with respect to the orthogonal laminated plate 10 and the like, the width of the lamina constituting each layer is unified to the same size except for the second outer layer 32 of the orthogonal laminated plate 30. However, laminaes having different widths may be mixed in each layer. good. The height of the convex part 16 and the depth of the concave part 17 can be adjusted by mixing laminaes having different widths in one layer. For example, in the case of the orthogonal laminated plate 10, the width of the lamina 141 arranged at the right end in the short side direction of the second inner layer 14 is increased by 50 mm to 250 mm, and the lamina 131 and the third constituting the first inner layer 13 are adjusted accordingly. The length of the lamina 151 constituting the inner layer 15 is increased by 50 mm to 1050 mm. In this case, the height of the convex portion 16 of the orthogonal assembly plate 10 is 150 mm, and the depth of the concave portion 17 is 100 mm.

  In addition, with respect to the orthogonal assembly plate 40, a lamina having a width that is half the width of the lamina 431 and 451 (100 mm) is applied to the end of the first inner layer 43 and the third inner layer 45 on the side where the recess 46 is formed. 431 and 451 and both ends in the longitudinal direction are aligned and the length of the lamina 441 is increased by 100 mm to 2900 mm accordingly. In this case, the depth of the recess 46 is 100 mm.

  As described above, when laminaes having a plurality of types of widths are mixed in one layer, the arrangement of the lamina is not particularly limited. For example, in the case of the orthogonal laminated plate 30, the second lamina 322 may be disposed around the center of the second outer layer 32 in the short side direction.

  Furthermore, when the convex part 16, the recessed part 17, etc. are formed in edge parts, such as the orthogonal assembly board 10, the number is one, However, A plurality may be provided. For example, a plurality of convex portions protruding at one end of the orthogonal assembly plate 10 or the like may be formed. In this case, the height and / or width of the plurality of convex portions may be the same. Furthermore, a plurality of recesses that are depressed at one end of the orthogonal assembly plate 10 or the like may be formed. In this case, the depth and / or width of the plurality of recesses may be the same. In addition, a plurality of protruding protrusions and recessed depressions may be mixed and formed at one end of the orthogonal assembly plate 10 or the like. In this case, the height of the convex portion and the depth of the concave portion may be the same or different. Further, the thickness of the convex portion and the thickness of the concave portion may be the same or different.

  Moreover, in 1st Embodiment, although the reinforcing bars 18 and 38 which consist of a round steel or a deformed reinforcing bar are arrange | positioned as a main reinforcement in the space parts 1737 and 4656, it replaces with all or one part of the reinforcing bars 18 and 38, and carbon fiber. Alternatively, reinforcing fibers made of reinforced fiber plastic, which are produced by impregnating a resin (matrix) into a reinforced fiber such as glass fiber or the like, may be disposed. In this case, it is desirable that the fiber direction of the reinforcing fiber included in the main reinforcement is the axial direction of the main reinforcement. Further, in addition to the main bar, a band bar that is orthogonal to the main bar may be disposed. Furthermore, it is not necessary to arrange the main muscle and the band. The cross-sectional shape, dimensions, and strength of the main bars are not particularly limited, but are desirably set appropriately according to the design strength.

  In addition, in the first embodiment, the orthogonal assembly plate 10 and the orthogonal assembly plate 30 are joined and integrated, or the orthogonal assembly plate 40 and the orthogonal assembly plate 50 are joined and integrated. In order to exert the reinforcing effect as described above, the gaps 1737 and 4656 are filled with concrete 19 and 39. However, the material of the filler to be filled in the gaps 1737 and 4656 is not limited to concrete, and has adhesiveness such as mortar, fluidity before solidification, and higher rigidity than wood after solidification. You may make it the material which has. Further, if the resin has such characteristics, the gaps 1737 and 4656 may be filled with a resin material. Note that the adhesiveness, fluidity, and rigidity of the filler are not particularly limited, but are desirably set as appropriate according to the shape and design strength of the gaps 1737 and 4656.

  Further, in the orthogonal assembly plates 10, 20, 30, and 40, the convex portion 16 and the concave portion 17 are formed at either the short side end portion or the long side direction end portion. Convex portions 16 and concave portions 17 may be formed at the ends in the short side direction and the long side direction of the plates 10, 20, 30, and 40. Furthermore, the combination of the convex portion 16 and the concave portion 17 formed on the orthogonal assembled plate 10 or the like may be changed as appropriate. For example, the concave portion 27 of the orthogonal assembly plate 20 may be constituted by the concave portion 37 of the orthogonal assembly plate 30.

  Further, regarding the orthogonal laminated plate 30, the second lamina 322 is replaced with a lamina 323 having a width of 75 mm wider than the second lamina 322. The orthogonal assembly plate in which the second lamina 322 is replaced with the lamina 323 is referred to as an orthogonal assembly plate 60. Furthermore, it is assumed that a concave portion 67 is formed in the orthogonal assembly plate 60 in place of the concave portion 37. Then, two orthogonal assembly plates 60 can be used to form a corner by joining at right angles, in other words, in an L shape. First, the two orthogonal assembly plates 60 are set on the floor so that the long side direction of the two orthogonal assembly plates 60 is orthogonal to the floor (not shown). Next, as shown in FIG. 11 (A), one (right side in FIG. 11 (A)) side surface of the orthogonal assembly plate 60 along the longitudinal direction of the lamina 323 and the other (left side in FIG. 11) orthogonal assembly. The surface of the outer edge part along the longitudinal direction of the lamina 323 of the board 60 is made to contact | abut. Further, the side surface along the longitudinal direction of the lamina 311 of one orthogonal assembly plate 60 is brought into contact with the surface of the outer edge portion along the longitudinal direction of the lamina 311 of the other orthogonal assembly plate 60. If it does so, the recessed part 67 of one orthogonal assembly board 60 and the recessed part 67 of the other orthogonal assembly board 60 will connect, and the L-shaped space | gap part 6767 will be formed.

  Then, similarly to the case of FIG. 7, when the reinforcing bars 68 are appropriately arranged in the gap 6767 along the long side direction of the orthogonal laminated plate 60 and the concrete 69 is placed, as shown in FIG. Two orthogonal assembly plates 60 are joined orthogonally with concrete 69, and a column 3B made of reinforcing bars 68 and concrete 69 is formed inside the joined two orthogonal assembly plates 60. As in the case of the gaps 1737 and 4656, a reinforcing fiber plastic main bar is arranged instead of the reinforcing bar 68, and instead of the concrete 69, it has adhesiveness and has fluidity before solidification and is solidified. Later, a material having higher rigidity than wood may be filled.

  Moreover, in 1st Embodiment, the convex parts 16 and 36 and the recessed parts 17 and 37 are formed by shifting the outer layers 11-12, 31-32, and the inner layers 13-15, 33-35 in the direction orthogonal to a lamination direction. However, it may be formed by notching (cutting) a part of the lamina of the orthogonal assembly plate which is not originally formed with the convex portions 16 and the concave portions 17.

  For example, FIG. 12 is a front view of the orthogonal assembly plate 70, in which a convex portion 76 is formed on the right side in the long side direction, and a concave portion 77 is formed on the left side. The orthogonal assembly plate 70 is assumed to have the same shape and dimensions as the orthogonal assembly plate 50 before the convex portions 76 and the concave portions 77 are formed.

  The convex portion 76 is formed by cutting the upper end of the right end and the lower end of the right end of the orthogonal assembly plate 50 shown in FIG. 9 along a long side direction with a rectangular cross section having a height of 45 mm and a width of 100 mm. The recess 77 is formed by cutting the center of the left end of the orthogonal assembly plate 50 shown in FIG. 9 along the long side direction with a rectangular cross section having a height of 45 mm and a width of 100 mm. As a result, the height of the convex portion 76 (the length along the short side direction of the orthogonal assembly plate 70) is 100 mm, and the width (the length along the stacking direction of the orthogonal assembly plate 70) is 45 mm. The depth of the recess 77 (the length along the short side direction of the orthogonal assembly plate 70) is 100 mm, and the width (the length along the stacking direction of the orthogonal assembly plate 70) is 45 mm. Thus, a convex part and a recessed part can also be formed by notching (cutting | disconnecting) the orthogonal | multiply laminated | stacked board which was originally not formed with the unevenness | corrugation in the circumferential direction suitably. In FIG. 12, the convex portion 76 is formed at the right end portion of the orthogonal assembly plate 70 and the concave portion 77 is formed at the left end portion, but the combination in which the convex portion 76 and the concave portion 77 are formed is appropriately set. You may do it. For example, the concave portion 77 is not formed, and only the convex portion 76 may be formed at one end portion. On the contrary, the convex part 76 may not be formed and only the concave part 77 may be formed at one end. Furthermore, the convex part 76 may be formed in any end part in the short side direction of the orthogonal assembly board 70. Further, a recess 77 may be formed at any end in the short side direction of the orthogonal assembly plate 70.

  Further, the shapes and dimensions of the gaps 1737, 4656, and 6767 are not limited to the above examples, and may be set as appropriate. Furthermore, the structure for forming the gaps 1737, 4656, and 6767 is not limited to the above example. For example, when the orthogonal assembly plate 10 and the orthogonal assembly plate 30 are joined in a T shape, the orthogonal assembly plate 30 disposed on the right side in FIG. 7 is replaced with the orthogonal assembly plate 10 and the orthogonal assembly plate 30 disposed on the left side. The width of the second lamina 322 may be increased by 45 mm to 90 mm, and the second lamina 322 may be connected to the lamina 111 of the first outer layer 11 of the replaced orthogonal laminated plate 10. Further, the width of the second lamina 322 of one orthogonal assembly plate 30 in FIG. 7 is narrowed, and the width of the second lamina 322 of the other orthogonal assembly plate 30 is increased by the same amount to connect the second laminas 322 to each other. May be.

  Further, the gap 1737 is formed by communicating the recess 17 and the recess 37 having the same width, but the width of the recess 17 and the recess 37 may be different. Similarly, the width of one of the two recesses 67 constituting the gap 6767 may be changed.

  Further, as shown in FIG. 13, the inner layers 13 to 15 can be extended to the left side in the short side direction to form the convex portions 16 and 86 at both ends in the short side direction. For example, the lamina 141 is arranged in the same direction on the left side of the lamina 141 arranged at the left end of the second inner layer 14 shown in FIG. 2 without any gaps, and the left end in the short side direction of the inner layer 14 and the short sides of the inner layers 13 and 15 are arranged. The laminas 131 and 151 constituting the inner layers 13 and 15 are elongated 200 mm to the left in the short side direction so that the left ends in the side direction are aligned. Then, as shown in FIG. 13, a convex portion 86 that is symmetric with respect to the convex portion 16 is formed at the left end of the orthogonal assembly plate 10.
