Description

[Technical Field]

[0001] The present invention relates to buildings. [Background technology]

[0002] For example, as disclosed in Patent Document 1, a conventional building is known that includes a hipped roof with multiple roof sections and an upright section such as an exterior wall erected on the roof section. In this type of building, it is necessary to install a structure at the boundary between the roof section and the upright section to prevent water such as rainwater from seeping in from the boundary section to the upright section.

[0003] In the technology disclosed in Patent Document 1, the boundary between the roof portion and the standing portion is located at the top of the roof portion, and a structure including a flashing cover is installed at the boundary portion. In this case, because the boundary between the roof portion and the standing portion is located at the top of the roof portion, water around the boundary portion flows down along the roof portion via the flashing cover.

[0004] A hip roof has a ridge that forms the top of the hip roof, and protruding parts such as corner ridges that extend downward from the ridge and protrude upward from the top surface of the roof. The boundary between the roof and the vertical part may be located below the ridge and intersect with the protruding part. In this case, water on the roof will flow along the roof toward the boundary between the roof and the vertical part. Water that reaches the boundary between the roof and the vertical part may accumulate in the area between the roof, the vertical part, and the protruding part.

[0010] Hereinafter, a building according to an embodiment of the present invention will be described with reference to the drawings.

[0011] [Building composition] 1 to 6, the building 1 according to this embodiment has a structure in which a building main body having a hip roof 2 and a building main body having exterior wall portions 3 connected to the hip roof 2 are connected horizontally. Furthermore, the building 1 is provided with water guides 4 that guide water such as rainwater flowing along the hip roof 2 to the side of the exterior wall portions 3.

[0012] <About hip roofs> The hip roof 2 has a first roof section 21 and a second roof section 22 that are horizontally adjacent to each other, a corner ridge section 23, and a ridge section 24. The ridge section 24 is a ridge that extends horizontally at the top of the hip roof 2. The ridge section 24 forms the uppermost part of the first roof section 21.

[0013] The first roof section 21 and the second roof section 22 are roof sections that slope downward relative to the ridge section 24. The first roof section 21 has a first sheathing board 211 that slopes downward relative to the ridge section 24, a roofing material 71 that covers the upper surface of the first sheathing board 211 to waterproof the first sheathing board 211, and a first ground tile 212 that is arranged on the roofing material 71 so as to be hooked onto a first tile beam 213. As shown in FIG. 5 , the first ground tile 212 is fixed to the first sheathing board 211 with a fixing member 8 such as a nail. The first ground tile 212, which is located lowest on the first sheathing board 211, is supported from below by a ground tile support member 73. Similarly, the second roof portion 22 has a second sheathing board 221 that slopes downwardly relative to the ridge portion 24, a roofing material 71 that covers the upper surface of the second sheathing board 221 to waterproof the second sheathing board 221, and a second base tile 222 that is arranged on the roofing material 71 so as to be hooked onto a second tile batten 223.

[0014] The corner ridge portion 23 is a ridge provided at the boundary between the first roof portion 21 and the second roof portion 22 so as to extend downward from the ridge portion 24. As shown in Fig. 3, the corner ridge portion 23 is an example of a protruding portion that protrudes upward from the roof upper surface 2121 of the first roof portion 21, which is formed by the upper surface of the first ground tile 212. The protruding portion is not limited to the corner ridge portion 23, as long as it protrudes upward from the roof upper surface 2121 of the first roof portion 21.

[0015] The corner ridge section 23 includes a corner ridge base 231 installed at the boundary between the first sheathing board 211 and the second sheathing board 221, a waterproofing material 72 covering the corner ridge base 231, and a corner ridge tile 232 fixed to the corner ridge base 231 via the waterproofing material 72 with fixing members 8 such as nails. Note that a roofing material 71 covering the first sheathing board 211 and the second sheathing board 221 is inserted between the corner ridge base 231 and the waterproofing material 72. The corner ridge base 231 is an example of a protrusion main body provided at the boundary between the first roof section 21 and the second roof section 22. The corner ridge tile 232 is an example of a covering member attached to the upper surface of the protrusion main body while covering the protrusion main body and the first roof section 21 from above.

[0016] <About the exterior walls> The outer wall 3 is a wall having an erected portion 31 erected on the first roof portion 21. The erected portion 31 is a wall connected to the first roof portion 21 and has a first wall 311 that extends in the horizontal and vertical directions and faces the ridge portion 24, and a pair of second walls 312A, 312B that extend from one horizontal end and the other horizontal end of the first wall 311 in a direction away from the ridge portion 24.

[0017] The first wall 311 is connected to the first roof portion 21 and the second roof portion 22 so that one horizontal end is located closer to the second roof portion 22 than the corner ridge portion 23 and the other horizontal end is located on the first roof portion 21. As shown in FIGS. 2 and 5 , the first wall 311 extends from a portion of the corner ridge portion 23 below the ridge portion 24 toward the first roof portion 21, opposite the second roof portion 22, and has a side surface 311A ​​facing the ridge portion 24. In other words, the side surface 311A ​​of the first wall 311 is a wall surface that extends horizontally and vertically toward the ridge portion 24. One horizontal end of the side surface 311A ​​of the first wall 311 is connected to a portion of the corner ridge portion 23 below the ridge portion 24, and the other horizontal end extends horizontally so as to be away from the corner ridge portion 23. In this embodiment, the side surface 311A ​​of the first wall 311 extends horizontally in parallel with the ridge portion 24.

[0018] The first wall 311 also has a first wall panel 3111 connected to the first sheathing board 211 of the first roof portion 21 and defining the side surface 311A, a first siding material 3112 attached to cover the first wall panel 3111, and a waterproofing material 72 arranged between the first wall panel 3111 and the first siding material 3112. A roofing material 71 covering the first sheathing board 211 is inserted between the first wall panel 3111 and the first siding material 3112. The first wall 311 also has a wall flashing material 5 for preventing water from entering a region of the first wall panel 3111 below the lower end of the first siding material 3112. The wall flashing material 5 is fixed to the first wall panel 3111 with fixing members 8 such as nails.

[0019] Of the pair of second walls 312A, 312B, the second wall 312A extends from one horizontal end of the first wall 311 in a direction away from the ridge portion 24. On the other hand, the second wall 312B extends from the other horizontal end of the first wall 311 in a direction away from the ridge portion 24.

[0020] As shown in FIG. 6 , the pair of second walls 312A, 312B includes a second wall panel 3121 connected to the first sheathing board 211 of the first roof section 21, a second siding material 3122 attached to cover the second wall panel 3121, and a waterproofing material 72 disposed between the second wall panel 3121 and the second siding material 3122. A roofing material 71 covering the first sheathing board 211 is inserted between the second wall panel 3121 and the second siding material 3122. The pair of second walls 312A, 312B also includes a wall flashing material 5 for preventing water from entering the area of ​​the second wall panel 3121 below the lower end of the second siding material 3122. The wall flashing material 5 is fixed to the second wall panel 3121 with a fixing member 8 such as a nail.

[0021] <About water derivatives> The water guide 4 will be described with reference to Figures 7 and 8 in addition to Figures 1 to 6. Water on the first roof section 21, which is inclined downward relative to the ridge section 24, flows along the roof upper surface 2121 toward the first wall 311 of the standing section 31 that is erected on the first roof section 21. The water guide 4 is provided across the first roof section 21 and the side surface 311A ​​of the first wall 311 so as to guide the water flowing along the roof upper surface 2121 of the first roof section 21 to the side of the first wall 311.

[0022] Moreover, the water guide 4 is connected to the corner ridge portion 23 that protrudes upward from the roof upper surface 2121 of the first roof portion 21, and has a shape that prevents water from accumulating in the area between the corner ridge portion 23, the first roof portion 21, and the side surface 311A ​​of the first wall 311. Based on such a shape of the water guide 4, it is possible to prevent water flowing along the first roof portion 21 from accumulating in the area between the corner ridge portion 23, the first roof portion 21, and the side surface 311A ​​of the first wall 311.

[0023] The water guide base 4 has a water guide base 41 and a water guide plate 42. The water guide base 41 forms the base of the water guide base 4 and is provided across the first roof portion 21 and the side surface 311A ​​of the first wall 311 so as to cover the boundary portion between the first roof portion 21 and the first wall 311 from above. The water guide base 41 is connected to each of the first roof portion 21, the first wall 311, and the corner ridge portion 23. Specifically, as shown in FIGS. 4 and 5 , the water guide base 41 has a covering plate 410 provided across the first roof portion 21 and the side surface 311A ​​of the first wall 311 so as to cover the upper surface of the first sheathing board 211 of the first roof portion 21, and a plurality of support plates 414 that support the covering plate 410 from below. On its underside opposite to the upward-facing upper surface 41A, the covering board 410 has a roof connecting edge 411 connected to the first sheathing board 211 of the first roof section 21, a wall connecting edge 412 connected to the first wall panel material 3111 (side surface 311A) of the first wall 311, and a corner ridge side edge 413 including an area portion connected to the corner ridge base 231 of the corner ridge section 23.

[0024] In this embodiment, as shown in FIG. 5 , in the covering plate 410, the roof connecting edge 411 and the wall connecting edge 412 are at the same height in a cross-sectional view taken along a plane perpendicular to the side surface 311A ​​of the first wall 311 and the horizontal direction. That is, the upper surface 41A of the covering plate 410 is perpendicular to the side surface 311A ​​of the first wall 311. The upper surface 41A of the covering plate 410 slopes downward with increasing distance from the corner ridge portion 23. Also, as shown in FIG. 2 , in a plan view of the water guide base 41 seen from vertically above, the roof connecting edge 411 extends from the corner ridge portion 23 to the other horizontal end of the side surface 311A ​​of the first wall 311. Moreover, in a front view of the water guide base 41 seen from a direction perpendicular to the side surface 311A ​​of the first wall 311, the roof connecting edge 411 slopes downward with increasing distance from the corner ridge portion 23. The wall connecting edge 412 extends along the side surface 311A ​​from the corner ridge portion 23 to the other horizontal end of the side surface 311A ​​of the first wall 311.

[0025] Also, as shown in Figure 4, in the covering plate 410, the corner ridge side edge 413 is located closer to the first roof section 21 than the ridge core 23A of the corner ridge section 23 along the boundary between the first roof section 21 and the second roof section 22.

[0026] The multiple support plates 414 are arranged at predetermined intervals in the horizontal direction parallel to the side surface 311A ​​of the first wall 311 and support the covering plate 410 from below. As shown in FIG. 4 , a specific support plate 414A of the multiple support plates 414 located closest to the corner ridge portion 23 is connected to the side of the corner ridge base 231 facing the first roof portion 21. The surface 414AA of the specific support plate 414A connected to the corner ridge base 231 extends from the corner ridge-side edge 413 of the covering plate 410 to the upper surface of the first sheathing board 211. Therefore, the specific support plate 414A is located closer to the first roof portion 21 than the ridge line 23A of the corner ridge portion 23 along the boundary between the first roof portion 21 and the second roof portion 22.

[0027] The water guide plate 42 is a plate-like member that is disposed on the upper surface 41A of the covering plate 410 of the water guide base 41 and is provided across the first roof portion 21 and the side surface 311A ​​of the first wall 311. A roofing material 71 that covers the first sheathing board 211 is inserted between the water guide base 41 and the water guide plate 42.

[0028] As shown in FIGS. 2, 4 to 7, the water guide plate 42 has a water receiving portion 421, an eaves guide portion 422, a roof covering portion 423, a corner ridge covering portion 424, and a wall covering portion 425.

[0029] The water receiving portion 421 is the portion of the water guide plate 42 that is placed on the upper surface 41A of the covering plate 410. The water receiving portion 421 faces upward and has a water receiving surface 4211 that receives water flowing along the first roof portion 21. The water receiving portion 421 covers the upper surface 41A of the covering plate 410 while being placed on the upper surface 41A. The water receiving portion 421 has a water receiving roof-side edge 4212 that is located on the roof connecting edge 411 of the covering plate 410, a water receiving wall-side edge 4214 that is located on the wall connecting edge 412 of the covering plate 410, and a water receiving corner-ridge-side edge 4213 that is located on the corner-ridge-side edge 413 of the covering plate 410.

[0030] In this embodiment, as shown in Fig. 5, the water receiving portion 421 has a water receiving surface 4211 that receives water flowing along the first roof portion 21 and is parallel to the upper surface 41A of the covering plate 410. The water receiving roof-side edge 4212 and the water receiving wall-side edge 4214 are at the same height in a cross-sectional view taken along a plane perpendicular to the side surface 311A ​​of the first wall 311 and the horizontal direction. In other words, the water receiving surface 4211 of the water receiving portion 421 is perpendicular to the side surface 311A ​​of the first wall 311, just like the upper surface 41A of the covering plate 410. The water receiving surface 4211 of the water receiving portion 421 slopes downward as it moves away from the corner ridge portion 23. This allows the water received by the water receiving surface 4211 to flow away from the corner ridge portion 23. Therefore, water can be more reliably prevented from pooling in the area between the corner ridge portion 23, the first roof portion 21, and the side surface 311A ​​of the first wall 311.

[0031] 2, in a plan view of the water receiving portion 421 seen from vertically above, the water receiving roof-side edge 4212 extends from the corner ridge portion 23 to the other horizontal end of the side surface 311A ​​of the first wall 311, similar to the roof connecting edge 411 of the covering plate 410. Moreover, in a front view of the water receiving portion 421 seen from a direction perpendicular to the side surface 311A ​​of the first wall 311, the water receiving roof-side edge 4212 slopes downward as it moves away from the corner ridge portion 23, similar to the roof connecting edge 411 of the covering plate 410. This allows water that flows along the first roof portion 21 and reaches the water receiving roof-side edge 4212 of the water receiving portion 421 to flow along the water receiving roof-side edge 4212 and away from the corner ridge portion 23. This more reliably prevents water from accumulating in the area between the corner ridge portion 23, the first roof portion 21, and the side surface 311A ​​of the first wall 311.

[0032] Like the wall connecting edge 412 of the covering plate 410, the water-receiving wall-side edge 4214 extends from the corner ridge portion 23 to the other horizontal end of the side surface 311A ​​of the first wall 311, along the side surface 311A.

[0033] 4 and 8, the water-receiving corner ridge-side edge 4213 of the water-receiving portion 421, like the corner ridge-side edge 413 of the covering plate 410, is located closer to the first roof portion 21 than the ridge core 23A of the corner ridge portion 23. In the corner ridge portion 23, the corner ridge tile 232 has a notch 2321 (FIG. 8) provided on the first roof portion 21 side with respect to the attachment position (ridge core 23A) to the corner ridge substrate 231 as a reference, so as to form a space for receiving the water-receiving corner ridge-side edge 4213 of the water-receiving portion 421. This allows the corner ridge tile 232 to cover the first roof portion 21 in areas other than the area where the water conductor 4 is provided, while allowing the water conductor 4 to be positioned adjacent to the corner ridge portion 23. The notch 2321 of the corner ridge tile 232 has a shape that is cut out, leaving the core portion located on the ridge core 23A. Because the corner ridge side edge 4213 of the water receiving portion 421, the corner ridge side edge 413 of the covering plate 410, and the specific support plate 414A are located closer to the first roof portion 21 than the ridge core 23A of the corner ridge portion 23, by providing a corner ridge tile 232 with a cutout portion 2321, the cutout portion 2321 can receive the water guide base 41 and the water receiving portion 421. This prevents the corner ridge tile 232 from being divided by the water guide 4, and allows the corner ridge tile 232 to be provided along the entire boundary between the first roof portion 21 and the second roof portion 22.

[0034] As shown in FIG. 2, the eaves guide portion 422 is a portion of the water guide plate 42 that extends from a portion of the water receiving portion 421 corresponding to the other horizontal end of the side surface 311A ​​of the first wall 311, along the second wall 312B, to the eaves edge of the first roof portion 21. As shown in FIG. 6, the eaves guide portion 422 has a water receiving connection portion 4221 that is connected to the water receiving portion 421, and a wall covering connection portion 4222 that is connected to the wall covering portion 425 described below. The eaves guide portion 422 guides water flowing on the water receiving surface 4211 of the water receiving portion 421 and away from the corner ridge portion 23, to the eaves edge of the first roof portion 21. This allows water flowing along the first roof portion 21 to be guided to the eaves edge of the first roof portion 21 via the water receiving portion 421 and the eaves guide portion 422.

[0035] 5 and 7, the roof covering portion 423 is a portion of the water guide plate 42 that extends from the water receiving roof side edge 4212 of the water receiving portion 421 toward the ridge portion 24 so as to cover the first sheathing board 211 of the first roof portion 21 from above. The roof covering portion 423 has an upper surface whose tip opposite the water receiving roof side edge 4212 positioned below the ground tile support material 73 on the first sheathing board 211 so that a covering upper surface 4231 constituting the upper surface is positioned below the roof upper surface 2121 of the first roof portion 21. The covering upper surface 4231 of the roof covering portion 423 is connected to the water receiving surface 4211 of the water receiving portion 421 via the water receiving roof side edge 4212. The roof covering portion 423 transfers water that has flowed along the roof upper surface 2121 of the first roof portion 21 and reached the covering upper surface 4231 to the water receiving surface 4211 via the water receiving roof side edge 4212.

[0036] 4 and 7, corner ridge covering portion 424 is a portion of water guide plate 42 that covers corner ridge substrate 231. Corner ridge covering portion 424 has a hanging portion 4241 that extends downward from a region above corner ridge substrate 231 at water receiving corner ridge-side edge 4213 of water receiving portion 421 to cover a specific support plate 414A from the side, and a covering portion 4242 that extends horizontally from the lower end of hanging portion 4241. Covering portion 4242 of corner ridge covering portion 424 is an example of a covering portion that covers corner ridge substrate 231 (protruding portion main body) from above in water guide plate 42 and is provided so as to overlap corner ridge tile 232 (covering member) vertically. With the covered portion 4242 of the corner ridge covering part 424 covering the corner ridge substrate 231 from above, the corner ridge tile 232 is attached to the corner ridge substrate 231 so as to overlap the covered portion 4242. As a result, the corner ridge tile 232 and the covered portion 4242 overlap vertically with the covered portion 4242 positioned below the corner ridge tile 232 above the corner ridge substrate 231. Because the corner ridge tile 232 and the covered portion 4242 overlap vertically, it is possible to prevent water from entering the connection portion between the corner ridge part 23 and the water guide 4.

[0037] 5 and 7, the wall covering portion 425 is a portion of the water guide plate 42 that extends upward from the water receiving wall-side edge 4214 of the water receiving portion 421 along the side surface 311A ​​of the first wall 311 to cover the side surface 311A. The wall covering portion 425 prevents water on the water receiving surface 4211 of the water receiving portion 421 from reaching the side surface 311A ​​of the first wall 311.

[0038] As described above, in the building 1 of this embodiment, the water guide 4 provided across the first roof portion 21 and the side surface 311A ​​of the first wall 311 can prevent water flowing along the roof top surface 2121 of the first roof portion 21 from accumulating in the area between the corner ridge portion 23, the first roof portion 21, and the first wall 311.

[0039] [Building construction procedure] Next, the construction procedure for the building 1 will be described with reference to FIGS. 9 to 16 in addition to FIGS.

[0040] First, the framework of the hip roof 2 and the exterior wall sections 3 is installed. Specifically, for the hip roof 2, the first sheathing board 211 of the first roof section 21 and the second sheathing board 221 of the second roof section 22 are installed. For the exterior wall sections 3, the first wall panel 3111 of the first wall 311 that constitutes the standing section 31 and the second wall panel 3121 that constitutes the pair of second walls 312A, 312B are installed. In this state, as shown in FIG. 9 , the corner ridge base 231 of the corner ridge section 23 is installed. At this time, the corner ridge base 231 is fixed in place by abutting against the first wall panel 3111 and the second wall panel 3121 at the boundary between the first sheathing board 211 and the second sheathing board 221.

[0041] 9, the water guide base 41 is installed so as to cover from above the boundary portion between the first sheathing board 211 and the first wall board 3111. At this time, the water guide base 41 is installed so as to be connected to the first sheathing board 211 and the first wall board 3111, and also to the corner ridge base 231.

[0042] 10, roofing material 71 is placed so as to cover the upper surfaces of the first sheathing board 211 and the second sheathing board 221.

In addition, a corner ridge tile 232 is fixed onto the corner ridge base 231 via the waterproofing material 72.

[0051] Through construction in accordance with the above construction procedure, a building 1 can be constructed that includes a hip roof 2 with a corner ridge portion 23, an exterior wall portion 3 with an upright portion 31 erected on a first roof portion 21 of the hip roof 2, and a water guide 4 for guiding water flowing along the first roof portion 21 to the side of the upright portion 31. As described above, in the building 1, the water guide 4 can prevent water flowing along the first roof portion 21 from accumulating in the area between the corner ridge portion 23, the first roof portion 21, and the side surface 311A ​​of the first wall 311 at the upright portion 31.

[0052] [About modified embodiments of the building] Although the building 1 according to the embodiment of the present invention has been described above, the present invention is not limited to this, and for example, the following modified embodiments can be adopted.

[0053] In the above embodiment, the water guide base 41 and water guide plate 42 that constitute the water guide 4 are configured such that the roof connecting edge 411 and the wall connecting edge 412 of the covering plate 410 are at the same height position when viewed in cross section from the side surface 311A ​​of the first wall 311 and a plane perpendicular to the horizontal direction, and the water receiving roof side edge 4212 and the water receiving wall side edge 4214 of the water receiving portion 421 of the water guide plate 42 are at the same height position when viewed in cross section from the side surface 311A ​​of the first wall 311 and a plane perpendicular to the horizontal direction, but this is not limited to this.

[0054] As shown in FIG. 17 , in the covering plate 410 of the water guide base 41, the wall connecting edge 412 may be located higher than the roof connecting edge 411 in a cross-sectional view taken along a plane perpendicular to the side surface 311A ​​of the first wall 311 and the horizontal direction. In this case, the upper surface 41A of the covering plate 410 is inclined upward toward the side surface 311A ​​of the first wall 311. The upper surface 41A of the covering plate 410 is inclined downward with increasing distance from the corner ridge portion 23. In addition, the roof connecting edge 411 extends from the corner ridge portion 23 to the other horizontal end of the side surface 311A ​​of the first wall 311 in a plan view of the water guide base 41 seen from vertically above. Moreover, the roof connecting edge 411 is inclined downward with increasing distance from the corner ridge portion 23 in a front view of the water guide base 41 seen from a direction perpendicular to the side surface 311A ​​of the first wall 311.

[0055] In a configuration in which the upper surface 41A of the covering plate 410 is inclined upward toward the side surface 311A ​​of the first wall 311, in the water receiving portion 421 of the water guide plate 42, the water receiving wall-side edge 4214 is located higher than the water receiving roof-side edge 4212 in a cross-sectional view taken along a plane perpendicular to the side surface 311A ​​of the first wall 311 and the horizontal direction. In other words, the water receiving surface 4211 of the water receiving portion 421, which is a plane parallel to the upper surface 41A of the covering plate 410, is inclined upward toward the side surface 311A ​​of the first wall 311, similar to the upper surface 41A of the covering plate 410. The water receiving surface 4211 of the water receiving portion 421 is inclined downward as it moves away from the corner ridge portion 23.

[0056] Furthermore, in a plan view of the water receiving portion 421 seen from vertically above, the water receiving roof side edge 4212 extends from the corner ridge portion 23 to the other horizontal end of the side surface 311A ​​of the first wall 311, similar to the roof connecting edge 411 of the covering plate 410. Moreover, in a front view of the water receiving portion 421 seen from a direction perpendicular to the side surface 311A ​​of the first wall 311, the water receiving roof side edge 4212 slopes downward as it moves away from the corner ridge portion 23, similar to the roof connecting edge 411 of the covering plate 410.

[0057] With this configuration of the water receiving section 421, the water receiving surface 4211 is inclined upward toward the side surface 311A ​​of the first wall 311, so that water received by the water receiving surface 4211 by flowing along the first roof section 21 is returned to the water receiving roof side edge 4212. Because this water receiving roof side edge 4212 is inclined downward as it moves away from the corner ridge section 23, the water returned to the water receiving roof side edge 4212 can be made to flow along the water receiving roof side edge 4212, away from the corner ridge section 23. This makes it possible to more reliably prevent water from accumulating in the area between the corner ridge section 23, the first roof section 21, and the side surface 311A ​​of the first wall 311.

[0058] In the above embodiment, the water receiving portion 421 of the water guide plate 42 is configured such that the water receiving roof side edge 4212 located on the roof connecting edge 411 of the covering plate 410 and the water receiving surface 4211 are each inclined downward with increasing distance from the corner ridge portion 23, but this is not limiting. In the water receiving portion 421, it is sufficient that at least one of the water receiving surface 4211 and the water receiving roof side edge 4212 is inclined downward with increasing distance from the corner ridge portion 23.

[0059] In the above embodiment, the corner ridge portion 23 was described as an example of a protruding portion that protrudes upward from the roof upper surface 2121 of the first roof portion 21 in the hip roof 2, but this is not limiting. The protruding portion is not limited to the corner ridge portion 23 as long as it protrudes upward from the roof upper surface 2121 of the first roof portion 21.

[0060] The above-described specific embodiments mainly include inventions having the following configurations.

[0061] A building according to one aspect of the present invention comprises a hipped roof having first and second roof sections horizontally adjacent to each other, a protruding section provided at the boundary between the first and second roof sections and protruding upward from the upper surface of the first roof section, an upright section provided on the first roof section, extending from a portion of the protruding section below the top of the first roof section to the opposite side from the second roof section and having a side surface facing the top of the first roof section, and a water conductor provided across the first roof section and the side surface of the upright section to direct water flowing along the first roof section to the side of the upright section. The water conductor is connected to the protruding section and has a shape to prevent water from accumulating in the area between the protruding section, the first roof section, and the upright section.

[0062] According to this building, water on the first roof section flows along the first roof section toward the side of the standing section erected on the first roof section. Because a water guide is provided between the first roof section and the side of the standing section, water flowing along the first roof section can be guided to the side of the standing section by the water guide. Moreover, the water guide is connected to a protruding section that protrudes upward from the top surface of the first roof section, and has a shape that prevents water from accumulating in the area between the protruding section, the first roof section, and the standing section. Based on this shape of the water guide, water flowing along the first roof section can be prevented from accumulating in the area between the protruding section, the first roof section, and the standing section.

[0063] In the above building, the water guide may face upward and include a water receiving surface that receives water flowing along the first roof portion, and the water receiving surface may be configured to slope downward as it moves away from the protruding portion.

[0064] In this embodiment, the water receiving surface of the water guide receives water flowing along the first roof portion. Because this water receiving surface slopes downward as it moves away from the protruding portion, the water received by the water receiving surface can flow away from the protruding portion. This more reliably prevents water from accumulating in the area between the protruding portion, the first roof portion, and the standing portion.

[0065] In the above-described building, the connecting edge of the water guide connected to the first roof portion may be configured to slope downward as it moves away from the protruding portion.

[0066] In this embodiment, the connecting edge of the water conductor that connects to the first roof portion slopes downward as it moves away from the protruding portion, so that water that flows along the first roof portion and reaches the connecting edge of the water conductor can flow along the connecting edge away from the protruding portion, thereby more reliably preventing water from accumulating in the area between the protruding portion, the first roof portion, and the standing portion.

[0067] In the above-mentioned building, the protrusion has a protrusion main body provided at the boundary between the first roof portion and the second roof portion, and a covering member attached to the upper surface of the protrusion main body while covering the protrusion main body and the first roof portion from above, and the covering member may be configured to have a cutout portion provided at a position on the first roof portion side based on the attachment position relative to the protrusion main body so as to form a space for receiving the protrusion-side end of the water derivative.

[0068] In this embodiment, the water conductor can be disposed adjacent to the protruding portion while the covering member covers the first roof portion in an area other than the area where the water conductor is provided. Furthermore, by providing the covering member with a cutout portion, the covering member can be prevented from being divided by the water conductor, and therefore the covering member can be provided over the entire boundary between the first and second roof portions.

[0069] In the above-described building, the water guide may have a covering portion that covers the protrusion main body from above and is arranged to overlap the covering member vertically.

[0070] In this embodiment, the covering member of the protrusion and the covering portion of the water conductor are vertically overlapped, so that it is possible to prevent water from entering the connecting portion between the protrusion and the water conductor.

[0071] As described above, according to the present invention, a building can be provided that can prevent water flowing along the first roof portion from accumulating in the area between the protruding portion, the first roof portion, and the standing portion.
