A plate member 1A shown in FIG. 10 is, like the plate member 1 described above, a sheet of flat rectangular wood-based material having a thickness of about 90 mm, and is formed of, for example, CLT.

This plate material 1A is cut in parallel to the longitudinal direction and perpendicular to the plate surface 11A at intervals of the same longitudinal length, for example, about 600 mm in short side dimension, and cut into partial plate materials 2A and 3A. Each of the partial plate members 2A and 3A is a horizontally long rectangular plate member having the same shape.

The partial plate 2A is cut diagonally in the lateral direction and perpendicular to the plate surface 11A so that the adjacent cut surfaces face in alternate directions at the three first to third cut surfaces 41A to 43A. As a result, the partial plate member 2A is cut into the first trapezoidal plate member 21A to the fourth trapezoidal plate member 24A.

Similar to the partial plate 2A, the partial plate 3A is cut obliquely in the transverse direction so that the adjacent cut surfaces face alternately at the three cut surfaces 51A to 53A. As a result, the partial plate member 3A is cut into the first trapezoidal plate member 31A to the fourth trapezoidal plate member 34A.

The cut surfaces 41A to 43A and 51A to 53A of the adjacent partial plate members 2A and 3A are configured to be substantially symmetrical with respect to the cut surface in the longitudinal direction. As a result, the first trapezoidal plate member 21A to the fourth trapezoidal plate member 24A have substantially the same shape as the first trapezoidal plate member 31A to the fourth trapezoidal plate member 34A, respectively.

In this first modified example, in addition to the embodiment described above, the first trapezoidal plate member 21A and the first trapezoidal plate member 24A have substantially the same shape, and the second trapezoidal plate member 22A and the third trapezoidal plate member 23A have substantially the same shape. configured as follows.

Each of the partial plate members 2B and 3B is a horizontally elongated rectangular trapezoidal plate member having the same shape.

The partial plate material 2B is cut obliquely in the lateral direction and perpendicular to the plate surface 11B so that the adjacent cut surfaces face in alternate directions at the four first to fourth cut surfaces 41B to 44B. As a result, the partial plate member 2B is cut into the first trapezoidal plate member 21B to the fifth trapezoidal plate member 25B.

Similar to the partial plate 2B, the partial plate 3B is cut obliquely in the short direction so that adjacent cut surfaces face alternate directions at the four first to fourth cut surfaces 51B to 54B. As a result, the partial plate member 3B is cut into the first trapezoidal plate member 31B to the fifth trapezoidal plate member 35B.

The cut surfaces 41B to 44B and 51B to 54B of the adjacent partial plates 2B and 3B are configured to be substantially symmetrical with respect to the cut surface in the longitudinal direction. As a result, the first trapezoidal plate member 21B to the fifth trapezoidal plate member 25B have substantially the same shape as the first trapezoidal plate member 31B to the fifth trapezoidal plate member 35B, respectively.

In the second modified example, unlike the above-described embodiment, the leftmost first trapezoidal plate members 21B and 31B are configured to have a general trapezoidal shape instead of a right-angled trapezoidal shape.

After that, the first trapezoidal plate material 21B to the fifth trapezoidal plate material 25B and the first trapezoidal plate material 31B to the fifth trapezoidal plate material 35B are assembled by a construction method similar to the method described above with reference to FIGS.

Each of the partial plate members 2C and 3C is a horizontally long rectangular plate member having the same shape.

The partial plate 2C is cut diagonally in the lateral direction and perpendicular to the plate surface 11C so that the adjacent cut surfaces face in alternate directions at the four first to fourth cut surfaces 41C to 44C. As a result, the partial plate member 2C is cut into the first trapezoidal plate member 21C to the fifth trapezoidal plate member 25C.

Similar to the partial plate 2C, the partial plate 3C is cut obliquely in the short direction so that adjacent cut surfaces face alternate directions at the four first to fourth cut surfaces 51C to 54C. As a result, the partial plate member 3C is cut into the first trapezoidal plate member 31C to the fifth trapezoidal plate member 35C.

In the adjacent partial plates 2C and 3C, the cut surfaces 41C to 44C and 51C to 54C are configured to be substantially symmetrical with respect to the cut surface in the longitudinal direction.

After that, the first trapezoidal plate 21C to the fifth trapezoidal plate 25C and the first trapezoidal plate 31C to the fifth trapezoidal plate 35C are assembled by a construction method similar to the method described above with reference to FIGS. A building structure 7C as shown in 17 is constructed. Such a building structure 7C is a building structure that is easily built based on a single flat board 1C (see FIG. 16) and that can realize columns, walls and a ceiling.

According to the building structure 7C according to the third modified example, in addition to the features and effects of the above-described embodiment, as shown in FIG. It can be a high structure compared to. This is because the length of the upper and lower sides of the first trapezoidal plate member 21C is longer than the length of the upper and lower sides of the fifth trapezoidal plate member 25C.

Although one embodiment of the present invention has been described above, the above embodiment shows one application example of the present invention, and the purpose of limiting the technical scope of the present invention to the specific configuration of the above embodiment. isn't it.

For example, in the above description, the plate 1 is cut into the partial plates 2 and 3, and the partial plates 2 and 3 are cut into the first to fifth trapezoidal plates 21 to 25 and the first to fifth trapezoidal plates 31 to 35, respectively. In the case of cutting into two, the case of cutting perpendicular to the plate surface 1A has been described as an example, but the present invention is not limited to this case. For example, when cutting along a slanted cut surface with respect to the plate surface 1A and joining each trapezoidal plate material produced as a result of cutting, the end surfaces (cut surfaces) of adjacent trapezoidal plate materials are joined together. good too.

Further, in the above description, the case where the partial plates 2 and 3 are respectively cut by the four first to fourth cut surfaces 41 to 44 and the second to fifth cut surfaces 51 to 54 is taken as an example. Although described, it is not limited to this case. For example, by increasing the number of cut surfaces, it is possible to make the shape more approximate to a curve when viewed from the side as shown in FIGS.

Further, in the above description, the case of constructing a building structure based on a single flat plate-like and rectangular plate material 1 has been described as an example, but the present invention is not limited to this case. For example, a building may be constructed based on a plurality of flat and rectangular plate materials.

Also, in the above description, the case where the plate material 1 and the like is CLT was described as an example, but the material is not limited to CLT. The board 1 may be, for example, a wood board with a conventionally used wooden material as a core or a wood board with a two-by-four material as a core.
