Embodiments for Carrying Out the Invention
[0024] First, a building 1 using a panel intersection fitting 11 and an angle adjustment fitting 16 according to an embodiment of the present invention will be described.
[0025] FIG. 1 is a schematic view showing a building 1 using a panel intersection fitting 11 and an angle adjustment fitting 16 according to an embodiment of the present invention. FIG. 2 is a view showing a state in which a wall panel 3 is fastened using a panel intersection fitting type V12 which is a form of the panel intersection fitting 11 according to an embodiment of the present invention.
[0026] The building 1 has, at the upper part of the building 1, a dome structure composed of the upper half of a polyhedron whose bottom surface of the dome structure is a regular polygon. The bottom surface of the dome structure may be a regular decagon, a regular dodecagon, a regular pentadecagon, a regular octadecagon, or a regular icosagon, depending on the size and shape of the building 1. Note that the building 1 is not limited to having a dome structure at the upper part of the building 1, and the dome structure may be directly arranged at the foundation of the building 1.
[0027] The building 1 is not limited to the dome structure, and may have a structure having a dome structure in a part of the building 1, a structure in which at least a part of the building 1 is a part of a polyhedron, or a structure having a curved surface in a part of the outer wall surface of the building 1.
[0028] The dome structure of the building 1 is composed of a wall panel 3, a panel intersection fitting 11, and an angle adjustment fitting 16. The wall panel 3 is a plate-like body of a pentagon (pentagon module 33) or a hexagon (hexagon module 34) formed by combining a plurality of triangular modules 35 having a triangular shape via the panel intersection fitting 11, and the position of the center of gravity of the wall panel 3 protrudes outside the dome structure.
[0029] The triangular module 35 is a plate-like body of a triangle formed by combining a plurality of module panels 32 which are wooden plates. The peripheral portion of the triangular module 35 has a panel frame material 31 extending inward (inside the dome structure). The panel frame material 31 fastens adjacent wall panels 3 to each other via the panel intersection fitting 11 and the angle adjustment fitting 16. Further, the triangular module 35 may optionally have an auxiliary frame material 36 at an arbitrary position inside (inside the dome structure) in addition to the peripheral panel frame material 31 in order to reinforce the strength.
[0030] FIG. 3 is a plan view of type V of the panel intersection fitting 11 according to an embodiment of the present invention, and FIG. 4 is a plan view of type VI of the panel intersection fitting 11 according to an embodiment of the present invention. Further, FIG. 5 is a front view of the panel intersection fitting 11 according to an embodiment of the present invention.
[0031] The panel intersection fitting 11 includes a columnar center hub 14 and a plurality of hub plates 15 that radially extend from the side surface of the center hub 14. There are two types of the panel intersection fitting 11: a panel intersection fitting type V12 having five hub plates 15 and a panel intersection fitting type VI13 having six hub plates 15. Hereinafter, the panel intersection fitting type V12 and the panel intersection fitting type VI13 are collectively referred to as the panel intersection fitting 11. The panel intersection fitting type V12 is used for a pentagonal module 33, and the panel intersection fitting type VI13 is used for a hexagonal module 34, respectively.
[0032] The hub plate 15 has a V shape in which a cross section in a direction perpendicular to the extending direction opens to the outside of the dome structure (downward in the drawing). Further, the hub plate 15 extends while being inclined at an angle θ2 toward the inside of the dome structure (upward in the drawing) with respect to a direction perpendicular to the axial direction of the center hub 14. The V-shaped opening angle (inner angle) θ1 of the hub plate 15 and the angle θ2 in the extending direction of the hub plate 15 are equal, and each can take an angle of 0 to 30 degrees depending on the curvature of the dome structure.
[0033] When the outer wall surface of the building 1 is a flat surface, the V-shaped inner angle θ1 of the hub plate 15 and the angle θ2 in the extending direction of the hub plate 15 are 0 degrees. When the outer wall surface of the building 1 has a structure that bends inward (the outer wall surface is a concave surface), the hub plate 15 may have a V shape in which a cross section in a direction perpendicular to the extending direction opens to the inside of the dome structure.
[0034] Next, the angle adjusting fitting 16 will be described. FIG. 6 is a side view (A) and a front view (B) of the angle adjusting fitting 16 according to an embodiment of the present invention.
[0035] The angle adjustment fitting 16 is composed of two plate-like bodies, one end of each plate-like body is connected, and it opens in a V shape on the outside of the dome structure.
[0036] The angle adjustment fitting 16 is arranged at a position separated from the tip of the hub plate 15 in the extending direction of the hub plate 15 when the panel intersection fitting 11 alone cannot tightly connect the adjacent wall panels 3 with sufficient strength. Therefore, when the panel intersection fitting 11 alone can tightly connect the adjacent wall panels 3 with sufficient strength, the angle adjustment fitting 16 may not be arranged. Also, the V-shaped inner angle θ1 of the hub plate 15, the angle θ2 in the extending direction of the hub plate 15, and the opening angle (inner angle) θ3 of the angle adjustment fitting 16 that opens in a V shape are equal.
[0037] The hub plate 15 and the angle adjustment fitting 16 each have one or more fastening bolt holes 41 for fastening the adjacent wall panel 3 or the triangular module 35 using a fastener 42.
[0038] FIG. 7 is a side view showing a state in which the wall panel 3 is fastened using the panel intersection fitting 11 according to an embodiment of the present invention. Note that the hub plates 15 and the center hub 14 other than the illustrated hub plate 15 are not shown. FIG. 8 is a plan view showing a state of a portion where the wall panel 3 is fastened using the angle adjustment fitting 16 according to an embodiment of the present invention. FIG. 9 is a plan view schematically showing the relationship between one hub plate 15 of the panel intersection fitting 11 according to an embodiment of the present invention, the angle adjustment fitting 16, and the panel frame material 31 of the wall panel 3. Note that the hub plates 15 and the triangular modules 35 other than the illustrated hub plate 15 are not shown.
[0039] The hub plate 15 and the angle adjustment fitting 16 have a fastener 42 that penetrates through the fastening bolt hole 41 and fastens the adjacent wall panel 3 or the triangular module 35 to the hub plate 15 and the angle adjustment fitting 16.
[0040] The fastening tool 42 includes a pair of fastening bolts 43 and fastening nuts 44, and a tapered fitting 45 disposed between the head of the fastening bolt 43 and each of the fastening nuts 44 and the wall panel 3 to ensure that the fastening bolt 43 and the fastening nut 44 can fasten the wall panel 3 to the hub plate 15 and the angle adjusting hardware 16. The tapered fitting 45 has a taper corresponding to the V-shaped opening angle (inner angle) θ1 of the hub plate 15 and the V-shaped opening angle (inner angle) θ3 of the angle adjusting hardware 16 to ensure that the fastening bolt 43 and the fastening nut 44 can fasten the wall panel 3 to the hub plate 15 and the angle adjusting hardware 16.
[0041] Next, a method of assembling the dome-shaped building 1 using the panel intersection hardware 11 will be described.
[0042] First, from the shape and size of the building 1 for which the construction is planned, the panel frame material 31, the module panel 32, and the auxiliary frame material 36 of the triangular module 35 used for the wall panel 3 are designed using CAD. Based on the design, wooden boards and square timbers are dimensioned, cut, and drilled to predetermined dimensions to form the panel frame material 31, the module panel 32, and the auxiliary frame material 36. Next, the panel frame material 31, the module panel 32, and the auxiliary frame material 36 are assembled to form the triangular module 35.
[0043] Thereafter, at the construction site of the building 1, the lowermost triangular module 35 is fastened to the floor (not shown) with a foundation anchor (not shown). Next, the triangular modules 35 are combined using the panel intersection hardware 11 having the V-shaped inner angle θ1 of the hub plate 15 corresponding to the curvature of the outer wall surface of the building 1 to form the pentagonal (pentagonal module) 33 or hexagonal (hexagonal module 34) wall panel 3. If sufficient strength cannot be obtained only with the panel intersection hardware 11, the required strength is obtained using the angle adjusting hardware 16. Then, the wall panels 3 are sequentially incorporated from the lower stage to the upper stage to temporarily assemble the dome-shaped building 1. After all the wall panels 3 are temporarily assembled, the fastening tool 42 is fastened to complete the building 1.
[0044] In addition, by using the panel intersection fittings 11, the wall panels 3 can be joined at any angle. Therefore, it is not limited to regular polygons, and an elliptical or outer wall with a changing curvature can also be formed. Further, the assembly accuracy of the wall panels 3 is improved, the structural study design time and the construction period can be shortened, and as a result, it is expected that the construction cost can be reduced.
[0045] As described above, the present invention has been described using embodiments. However, the technical scope of the present invention is not limited to the scope described in the above embodiments. It is obvious to those skilled in the art that various changes or improvements can be made to the above embodiments. It is clear from the description of the claims that forms with such changes or improvements can also be included in the technical scope of the present invention.
