[0010] <Embodiment> Referring to the drawings, the dome-shaped building 1 according to the embodiment will be described. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.

[0011] [Configuration of Dome-shaped Building] FIG. 1 is a diagram schematically showing the configuration of the dome-shaped building 1 according to the embodiment. The dome-shaped building 1 includes a dome-shaped outer surface 100. The outer surface 100 has a shape formed by combining a plurality of polygons 300. Therefore, the outer surface 100 includes a plurality of ridge lines 400 and a plurality of vertices 500 formed by the plurality of polygons 300. Among the plurality of vertices 500, the vertex 501 in the inner region of the outer surface 100 is also referred to as the "first vertex". In the present embodiment, each of the plurality of polygons 300 is a triangle. However, it is not limited thereto, and other polygons may be used.

[0012] Hereinafter, for the sake of simplicity, the vertex 501a among the vertices 501 in the inner region will be described. However, the following description is similarly applicable to other vertices among the vertices 501 in the inner region.

[0013] As shown in FIG. 1, six ridge lines 401 to 406 extend from the vertex 501a. Among such a plurality of ridge lines 400, the ridge line extending from the vertex 501 (first vertex) in the inner region is also referred to as the "first ridge line".

[0014] Further, the vertex 501a and the six ridge lines 401 to 406 are formed by polygons 301 to 306. Among such a plurality of polygons 300, the polygon forming the first vertex and the first ridge line is also referred to as the "first polygon".

[0015] FIG. 2 is a diagram schematically showing the configuration around the vertex 501a in the dome-shaped building 1 according to the embodiment. The dome-shaped building 1 includes bars 11 to 16, a connecting member 5, and facing members 21 to 26 around the vertex 501a.

[0016] The rod members 11-16 are positioned to coincide with the ridge lines 401-406. The connecting member 5 is provided at the vertex 501a and connects the multiple rod members 11-16 to each other. The connecting member 5 and the rod members 11-16 are connected using, for example, bolts (not shown).

[0017] Each of the facing materials 21 to 26 has a shape corresponding to polygons 301 to 306. Figure 3 shows an example of the shape of facing material 21 according to this embodiment. The facing material 21 has a corner portion 21a and two side portions 21b extending from the corner portion 21a. In this embodiment, the corner portion 21a has a shape lacking a tip, but is not limited to this, and may have a pointed tip. Also, in this embodiment, all of the facing materials 21 to 26 are plate materials and are made of transparent resin, wood, metal, etc.

[0018] Let's return to Figure 2 for further explanation. The facing materials 21-26 are arranged to coincide with polygons 301-306, respectively. For example, in the case of facing material 21, the two edges 21b coincide with the positions of edges 401 and 406 of polygon 301, respectively, and the corner 21a coincides with the position of vertex 501a of polygons 301-306. As a result, the two edges 21b of facing material 21 coincide with the positions of rods 11 and 16, respectively, and the corner 21a coincides with the position of connecting material 5. The same applies to facing materials 22-26.

[0019] Therefore, among the panel materials 21 to 26, for example, panel materials 21 and 22 are adjacent to each other. Furthermore, the edge 21b of panel material 21 and the edge 22b of panel material 22 face each other. A region P1 in which the edges of two adjacent panel materials face each other will hereafter be referred to as the "first region". In other words, there are six regions P1 in Figure 2. Also, any two adjacent panel materials among panel materials 21 to 26 will hereafter be referred to as the "two first panel materials".

[0020] Furthermore, the corners 21a to 26a of the facing materials 21 to 26 abut each other at the position of the connecting material 5. This part P2 where the corners 21a to 26a of the facing materials 21 to 26 abut each other will henceforth be referred to as the "second part".

[0021] The rod members 11-16, connecting members 5, and surface members 21-26 described above are configured for each of the vertices 500 located within the interior. This forms a dome-shaped outer surface 100 on the dome-shaped building 1.

[0022] It is desirable that such a dome-shaped building 1 be easily dismantled. This would allow the dome-shaped building to be dismantled in a short time, and materials such as the frame and facing materials to be reused. As a result, it is suitable for use as a temporary structure, for example, for events.

[0023] On the other hand, dome-shaped building 1 requires waterproofing performance so that it can be used outdoors. In this case, if the gaps between the rods and connecting members and the facing materials in dome-shaped building 1 are filled with sealant for waterproofing, the facing materials will be firmly bonded. As a result, disassembly will take time, and the facing materials may be damaged and become unusable. For this reason, there is a need for a dome-shaped building that is easy to disassemble while ensuring waterproofing performance.

[0024] In view of these problems, the dome-shaped building 1 according to this embodiment includes a first fixing part 50 that detachably seals and fixes a portion P1 where the edges of two adjacent facing materials meet, and a second fixing part 60 that detachably seals and fixes a portion P2 where the corners of multiple facing materials abut each other. This makes it possible to provide a dome-shaped building 1 that is easy to disassemble while ensuring waterproof performance. This will be described in detail below.

[0025] Figure 4 is a schematic diagram showing the configuration around the apex 501a of a dome-shaped building 1, in which the first fixing part 50 and the second fixing part 60 are provided. As shown in Figure 4, the first fixing part 50 (first fitting 51, described later) is provided at each part P1 where the edges of two adjacent surface materials face each other. In addition, the second fixing part 60 (fourth fitting 64, described later) is provided at the part P2 where the corners 21a to 26a of the surface materials 21 to 26 abut each other.

[0026] Figure 5 is a schematic diagram showing the configuration of the first fixing part 50 according to the embodiment. Figure 5 shows a cross-sectional view of the configuration at part P1 between the facing materials 21 and 22 in Figure 4, as seen from the direction of arrow A.

[0027] The first fixing part 50 includes a first fitting 51, a second fitting 52, and a third fitting 53. The second fitting 52 is, for example, a bent metal plate. Figure 6 shows an example of the cross-sectional shape of the second fitting 52. The second fitting 52 includes a bottom 52a, two side parts 52b and 52c, and two flange parts 52d and 52e. The bottom 52a has a hole h1 (first hole) through which the threaded portion of the screw 53a (described later) of the third fitting 53 passes. The side parts 52b and 52c rise from two positions on the periphery of the bottom 52a that are opposite each other, with the hole h1 in between. The flange parts 52d and 52e protrude outward from the upper ends of the side parts 52b and 52c, respectively.

[0028] Let's return to Figure 5 for further explanation. In this embodiment, the third component 53 is a screw 53a (first screw member). The screw 53a detachably fastens the second component 52 to the rod 11. As the second component 52 is fastened with the screw 53a, the flange portions 52d and 52e of the second component 52 press against the edges 21b and 22b of the face materials 21 and 22 toward the rod 11, respectively. In this way, the second component 52 detachably fixes the face materials 21 and 22 to the rod 11.

[0029] In this embodiment, the first fitting 51 is a rubber tape. Figure 7 is another schematic diagram showing the configuration of the first fixing part 50 according to this embodiment. Figure 7 shows the first fixing part 50 shown in Figure 5 as viewed from the direction of fastening of the third fitting 53. In this embodiment, when the second fitting 52 is pressing down on the edges 21b and 22b of the face materials 21 and 22, the dimensions S2 of the flange portions 52d and 52e in the longitudinal direction of part P1 are both shorter than the longitudinal dimension of part P1 (length of part P1) S1. In this embodiment, the dimensions S2 of the flange portions 52d and 52e are the same, but are not limited to this and may be different.

[0030] As shown in Figure 7, the first component 51 covers the second component 52 and detachably seals portion P1 over a length S1. In this way, the first fixing portion 50 fixes the portion P1 where the facing materials 21 and 22 face each other, while detachably sealing it.

[0031] Figure 8 is a schematic diagram showing the configuration of the second fixing part 60 according to the embodiment. Figure 8 shows a cross-sectional view of the configuration around vertex 501a in Figure 4, viewed from the direction of arrow B.

[0032] The second fixing part 60 includes a fourth fitting 64, a fifth fitting 65, a sixth fitting 66, and a seventh fitting 67. In this embodiment, the fourth fitting 64 is provided on the surface of the face materials 21-26 opposite to the surface facing the rod materials 11-16. The fourth fitting 64 has a main body 64a and an elastic member 64y. The main body 64a is made of, for example, plastic. The elastic member 64y is provided in an annular shape between the main body 64a and the face materials 21-26, surrounding part P2. The elastic member 64y is made of, for example, rubber.

[0033] The fifth component 65 is provided on the surface of the face materials 21-26 opposite to the surface on which the fourth component 64 is provided. In other words, the fifth component 65 is provided so as to sandwich the face materials 21-26 between the fourth component 64. The fifth component 65 is made of, for example, plastic.

[0034] Figure 9 shows an example of the shape of the main body 64a of the fourth component 64. The top of Figure 9 shows a top view of the main body 64a. In this embodiment, the outer shape of the main body 64a is circular. The bottom of Figure 9 shows a cross-sectional view of the main body 64a.

[0035] The main body 64a has a bottom wall 64b (first bottom wall), a side wall 64c, and a flange portion 64d. The bottom wall 64b has a hole h2 (second hole) through which the threaded portion of the bolt 66a (described later) of the sixth fitting 66 passes. The side wall 64c is provided around the bottom wall 64b. The flange portion 64d protrudes in an annular shape from the upper end of the side wall 64c. As shown in Figure 8, an annular elastic member 64y is provided on the lower surface of the flange portion 64d.

[0036] Figure 10 shows an example of the shape of the fifth component 65. The top of Figure 10 shows a top view of the fifth component 65. In this embodiment, the outer shape of the fifth component 65 is circular. The bottom of Figure 10 shows a cross-sectional view of the fifth component 65.

[0037] The fifth component 65 has a bottom wall 65a (second bottom wall) and a projection 65b. The bottom wall 65a has a hole h3 (third hole) through which the threaded portion of the bolt 66a (described later) of the sixth component 66 passes. The projection 65b is provided in an annular shape on the bottom wall 65a so as to surround the hole h3. The diameter of the annular projection 65b is the same as the diameter of the annular elastic member 64y of the fourth component 64. In other words, the annular projection 65b is provided so as to sandwich the face materials 21 to 26 between it and the annular elastic member 64y of the fourth component 64.

[0038] Let's return to Figure 8 for further explanation. The sixth component 66 includes a bolt 66a (second threaded member), a nut 66b, a spacer 66c, and a fitting 66d. Between the bolt 66a and the nut 66b, the fourth component 64, the fifth component 65, the connecting member 5, the spacer 66c, and the fitting 66d are provided in that order. Thus, the bolt 66a and the nut 66b detachably fasten the fourth component 64, the fifth component 65, the connecting member 5, the spacer 66c, and the fitting 66d to each other.

[0039] As a result, the facing materials 21-26 are sandwiched between the fourth fitting 64 and the fifth fitting 65 and detachably fixed to the connecting member 5. At the same time, the annular elastic member 64y is sandwiched between the main body 64a and the facing materials 21-26 and contracts. As a result, the main body 64a and the elastic member 64y of the fourth fitting 64 detachably seal portion P2. In this way, the second fixing part 60 detachably seals and fixes portion P2 where the corners of the facing materials 21-26 abut each other.

[0040] As described above, the dome-shaped building 1 according to this embodiment includes a first fixing part 50 that detachably seals and fixes a portion P1 where the edges of two adjacent facing materials face each other, and a second fixing part 60 that detachably seals and fixes a portion P2 where the corners of multiple facing materials abut each other. This makes it possible to provide a dome-shaped building 1 that is easy to disassemble while ensuring waterproof performance.

[0041] Furthermore, in Figure 8, the seventh component 67 is detachably attached to the main body 64a and seals the head of the bolt 66a together with the main body 64a. The seventh component 67 can be attached, for example, with double-sided tape (not shown). This prevents rust from forming on the head of the bolt 66a.

[0042] <Example 1> In the above embodiment, the case in which the first fixing part 50 is made of rubber tape has been described, but the invention is not limited to this. The first fixing part 51 may be made of aluminum tape. In this case, the first fixing part 51 can have higher waterproof performance and durability.

[0043] <Modification 2> In the above embodiment of the first fixing part 50, the width dimensions S2 of the two flange parts 52d and 52e of the second fitting 52 are both shorter than the length S1 of part P1, and the second fitting 52 is covered by the first fitting 51. However, the invention is not limited to this.

[0044] Figure 11 is a schematic diagram showing the configuration of the first fixing part 50A according to Modification 2. The first fixing part 50A according to Modification 2 includes a first component 51, a second component 52A, and a third component 53A.

[0045] The second component 52A is a metal plate with rust-preventive coating. Figure 12 shows an example of the cross-sectional shape of the second component 52A according to modified example 2. The second component 52A includes an upper wall 52h and two flange portions 52i and 52j. The upper wall 52h has a hole h1 through which the threaded portion of the screw 53a passes. The flange portions 52i and 52j protrude downward from two opposing positions on the periphery of the upper wall 52h, with the hole h1 in between.

[0046] Let's return to Figure 11 for explanation. The third component 53A includes a screw 53a, a collar 53b, and double-sided tape 53c. In terms of assembly order, first, the collar 53b is temporarily fixed to the rod 11 with the double-sided tape 53c. After that, the first component 51 and the second component 52A are attached to part P1 in order. That is, the first component 51 is placed between the two face materials 21, 22 and the second component 52A, and detachably seals part P1.

[0047] Then, the screw 53a passes through the first fitting 51 and detachably fastens the second fitting 52A to the rod 11. As the second fitting 52A is fastened with the screw 53a, the flange portions 52i and 52j of the second fitting 52A press against the edges 21b and 22b of the face materials 21 and 22 toward the rod 11, respectively. In this way, the second fitting 52A covers the first fitting 51 and detachably fixes the face materials 21 and 22 to the rod 11.

[0048] Figure 13 is another diagram schematically showing the configuration of the first fixing part 50A according to Modification 2. In Modification 2, when the second fitting 52A is pressing down on the edges 21b and 22b of the facing materials 21 and 22, the dimensions S3 of the upper wall 52h and flange parts 52i and 52j in the longitudinal direction of part P1 are all greater than or equal to the length S1 of part P1.

[0049] Therefore, the second component 52A can cover the entire length S1 of portion P1. As a result, the second component 52A according to the modified example 2 can fix the edges 21b and 22b of the facing materials 21 and 22 more firmly than the second component 52 according to the embodiment.

[0050] Furthermore, as shown in Figures 11 and 13, in Modification 2, the second component 52A is located on the outer surface of part P1. The second component 52A is a metal plate that has been painted with rust-preventive paint as described above. On the other hand, in the embodiment, the first component 51 is located on the outer surface of part P1, and the first component 51 is a rubber tape. Also, in Modification 1, the first component 51 is located on the outer surface of part P1, and the first component 51 is an aluminum tape. For this reason, the first fixing part 50A according to Modification 2 can have a better appearance than that of the embodiment and Modification 1.

[0051] <Variation 3> In the above embodiment, the case in which the main body portion 64a and the elastic member 64y seal portion P2 has been described, but the invention is not limited to this.

[0052] Figure 14 is a schematic diagram showing the configuration of the second fixing part 60A according to Modification 3. The second fixing part 60A according to Modification 3 includes a fifth fitting 65A and an aluminum tape 68.

[0053] The fifth component 65A has an annular projection 65c located inside the annular projection 65b. The aluminum tape 68 is formed in an annular shape. The inner end 68a of the aluminum tape 68 engages with the projection 65c of the fifth component 65A. On the other hand, the outer end 68b of the aluminum tape 68 engages between the elastic member 64y and the facing materials 21-26. As a result, even if liquid passes through the elastic member 64y, the aluminum tape 68 can stop the liquid at point P2. In this way, the aluminum tape 68 seals point P2. As a result, the waterproofing performance of the second fixing part 60A is further improved.

[0054] <Modification 4> In the dome-shaped building 1 according to the above embodiment, the case in which all of the facing materials 21 to 26 are made of board material has been described, but the invention is not limited to this. At least one of the facing materials 21 to 26 may be made of fabric (for example, fabric used for tents).

[0055] Figure 15 schematically shows the configuration of the first fixing part 50B in a dome-shaped building according to Modification 4. In Figure 15, the facing material 28 is a fabric material, and the facing material 21 is a board material. That is, at part P1, the edge 28b of the fabric facing material 28 and the edge 21b of the board facing material 21 face are opposite each other.

[0056] The first fixing part 50B according to Modification 4 includes a first fitting 51, a second fitting 52B, and a third fitting 53B. Figure 16 shows an example of the cross-sectional shape of the second fitting 52B according to Modification 4. The second fitting 52B includes a bottom portion 52a, a side portion 52b, and a flange portion 52d. The bottom portion 52a has a hole h1 through which the threaded portion of the screw 53a passes. The side portion 52b rises from a part of the periphery of the bottom portion 52a. The flange portion 52d protrudes outward from the upper end of the side portion 52c.

[0057] Let's return to Figure 15 for further explanation. The third component 53B has a screw 53a and a square washer 53d. In terms of assembly order, first the square washer 53d is placed on the face material 28. Then the second component 52B is installed such that its bottom portion 52a is positioned on the square washer 53d and its flange portion 52d is positioned on the face material 21. After that, the screw 53a is screwed into the rod 11, passing through the second component 52, the square washer 53d and the face material 28. In this way, the screw 53a detachably fastens the second component 52, the square washer 53d, the face material 28 and the rod 11 to each other.

[0058] As a result, the bottom portion 52a of the second component 52B presses the edge portion 28b of the face material 28 toward the rod 11 via the corner washer 53d. Also, the flange portion 52d of the second component 52B presses the edge portion 21b of the face material 21 toward the rod 11. In this way, the second component 52B detachably fixes the face materials 21 and 28 to the rod 11. Furthermore, the first component 51 covers the second component 52B and detachably seals portion P1.

[0059] Thus, even when the edge 28b of the fabric facing material 28 and the edge 21b of the board facing material 21 face are facing each other in part P1, the first fixing part 50B can fix part P1 while detachably sealing it.

[0060] Figure 17 is a schematic diagram showing the configuration of the second fixing part 60 in a dome-shaped building according to modified example 4. In Figure 17, the facing material 28 is a fabric material, and the facing material 21 is a board material. In other words, the fabric material is included in the multiple facing materials that form part P2. In this case, the thickness of the elastic member 64y is adjusted to match the thickness of the facing material 28. For example, the thickness of the part of the elastic member 64y that faces the facing material 28 is increased. As a result, the elastic member 64y is compressed by being sandwiched between the main body part 64a and the facing material 28. As a result, even if the multiple facing materials that form part P2 include fabric material, the second fixing part 60 can fix part P2 while detachably sealing it.

[0061] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive.
