Description

[Technical Field]

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

[0002] A building has a room with an interior space covered by a ceiling. The ceiling described in Patent Document 1 has a first plane and a second plane. The first plane is inclined so that the height increases as it approaches the second plane in the direction in which the first plane and the second plane are aligned in a plan view. The second plane is inclined so that the height increases as it approaches the first plane in the direction in which the first plane and the second plane are aligned in a plan view. The ceiling further has a connecting surface connecting the first plane and the second plane. The connecting surface is a plane extending horizontally. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-149609 Summary of the Invention [Problem to be solved by the invention]

[0004] In such a ceiling, the slope of the ceiling changes discontinuously at the boundary between the first plane and the connecting surface and at the boundary between the second plane and the connecting surface, which impairs the aesthetic appearance of the ceiling. [Means for solving the problem]

[0005] (1) A building that solves the above problem includes a room having an interior space covered by a ceiling, the ceiling having a first plane and a second plane, and when a direction in which the first plane and the second plane are aligned in a plan view is defined as a first direction, the first plane is inclined so that its height increases as it approaches the second plane in the first direction, and the second plane is inclined so that its height increases as it approaches the first plane in the first direction, and the ceiling further has a connection surface that connects the first plane and the second plane, and the connection surface is a curved surface that smoothly connects to an upper end of the first plane and an upper end of the second plane and curves upward, and a first plane portion including the first plane has a first lower surface that is The second plane portion including the second plane is composed of a plurality of second substrates whose second lower surface is a plane that slopes so that the height increases as it approaches the second plane and that are arranged side by side in a second direction that is perpendicular to the first direction in a planar view, and a first ceiling panel that is arranged along the first lower surface.The second plane portion including the second plane is composed of a plurality of second substrates whose second lower surface is a plane that slopes so that the height increases as it approaches the first plane in the first direction and that are arranged side by side in the second direction, and a second ceiling panel that is arranged along the second lower surface.The connection surface portion including the connection surface is composed of a plurality of third substrates whose third lower surface is a curved surface that curves upward and that are arranged side by side in the second direction, and a third ceiling panel that is arranged along the third lower surface.

[0006] According to this configuration, the connecting surface is smoothly connected to the upper end of the first plane and the upper end of the second plane. Furthermore, the connecting surface is a curved surface that curves upward. Therefore, the slope of the ceiling changes continuously in the first direction. This improves the aesthetic appearance of the ceiling. Furthermore, since the connecting planes do not create corners on the ceiling, the ceiling gives a soft impression. Therefore, the interior space has a feeling of being enveloped. Furthermore, light within the interior space can spread freely along the ceiling.

[0007] Furthermore, according to the above configuration, the connection surface portion is composed of a plurality of third substrates and a third ceiling panel. The third lower surface of the third substrate is a curved surface that curves upward. The plurality of third substrates are arranged side by side in the second direction. The third ceiling panel is arranged along the third lower surface of the third substrate. This makes it possible to form a highly accurate curved surface by arranging the third ceiling panel along the third lower surface of the third substrate, without having to prepare a curved third ceiling panel.

[0008] (2) In the building of (1) above, a ridge beam extends in the second direction, and each of the multiple third bases is arranged so that the apex of the third lower surface overlaps the ridge beam in the vertical direction.

[0009] According to this configuration, the ridge beam extends along the second direction. Therefore, by using the ridge beam as a guide to arrange the third bases in the direction in which the ridge beam extends, the third bases are arranged in the second direction. This makes it easier to arrange the third bases.

[0010] Furthermore, each third base is positioned so that the apex of the third lower surface overlaps the ridge beam in the vertical direction. This allows the multiple third bases to be positioned so that the apexes of the third lower surfaces are aligned in a straight line. This makes it possible to suppress misalignment of the third bases in the first direction.

[0011] (3) In the building described in (2) above, the upper end of the first substructure and the upper end of the second substructure each extend toward the ridge beam and are connected to the ridge beam, and in the second direction, the first substructure, the second substructure, and the third substructure are arranged in the same position, and the third substructure is in contact with the first lower surface and the second lower surface. According to this configuration, the third base can be stably disposed.

[0012] (4) In the building of any one of (1) to (3) above, a plastering material layer is provided on the underside of the first ceiling panel, the underside of the second ceiling panel, and the underside of the third ceiling panel.

[0013] According to this configuration, the boundary between the first ceiling panel and the third ceiling panel and the boundary between the second ceiling panel and the third ceiling panel are covered with the plastering material layer, further improving the aesthetic appearance of the ceiling.

[0014] (5) In the building of any one of (1) to (4) above, the connection surface has an arc shape in a side view seen from the second direction. This configuration further improves the aesthetic appearance of the ceiling.

[0015] (6) In any one of the buildings (1) to (5) above, the building has a wall portion extending along the first direction, and the second plane has a main body portion located above the lower end of the first plane and an extension portion located below the lower end of the first plane, the wall portion is located below the first plane, the connection surface, and the main body portion of the second plane, and the interior space has a first region located below the first plane, the connection surface, and the main body portion of the second plane, and a second region located below the extension portion of the second plane.

[0016] According to this configuration, the ceiling has an asymmetric shape with respect to the apex of the ceiling in the first direction. Therefore, the entire interior space is an asymmetric space with respect to the apex of the ceiling in the first direction. On the other hand, the first region is an area that is symmetric with respect to the apex of the ceiling in the first direction. By providing the wall portion in the first region, the wall portion has a symmetric shape with respect to the apex of the ceiling in the first direction, and therefore, when the interior space is viewed from the second direction, the fact that the first region is an area of symmetry is emphasized. By providing a symmetrical area in an asymmetric interior space in this way, the design of the interior space is improved.

[0017] Furthermore, since the ceiling height of the second area is lower than the ceiling height of the first area, people in the indoor space tend to feel a sense of openness when moving from the second area to the first area. [Effects of the Invention]

[0018] According to the building of the present invention, the aesthetic appearance of the ceiling can be improved. [Brief explanation of the drawings]

[0019] [Figure 1] This is a floor plan of part of the second floor of a building. [Figure 2] 2 is a cross-sectional view of the building taken along line 2-2 in FIG. 1. [Figure 3] A cross-sectional view of a ceiling. [Figure 4] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0020] A building 10 of this embodiment will be described with reference to Figures 1 to 4. The building 10 of this embodiment is a two-story detached house. The building 10 has a sloped roof 10b. The sloped roof 10b has a roof skeleton. The roof skeleton is made up of sloped beams (not shown) and a ridge beam 12 that supports the sloped beams. The building 10 has a ceiling 20 that is installed so as to follow the slope of the sloped roof 10b.

[0021] 1, a building 10 includes a room 10a having an interior space 11. The interior space 11 is provided on the second floor of the building 10. The interior space 11 is covered by a ceiling 20.

[0022] <Ceiling> As shown in FIG. 2, the room 10a has a ceiling 20. The interior space 11 is provided below the ceiling 20. The ceiling 20 has a first plane 21 and a second plane 22. In the following description, the direction in which the first plane 21 and the second plane 22 are aligned in a plan view is referred to as a first direction. The first plane 21 is inclined so that its height increases as it approaches the second plane 22 in the first direction. The second plane 22 is inclined so that its height increases as it approaches the first plane 21 in the first direction. That is, the first plane 21 and the second plane 22 are inclined so that they approach each other upward. The inclination angle of the first plane 21 with respect to the vertical direction is the same as the inclination angle of the second plane 22 with respect to the vertical direction. The direction perpendicular to the first direction is referred to as a second direction. In this embodiment, the ridge beam 12 extends along the second direction (see FIG. 3).

[0023] The ceiling 20 further has a connection surface 23 that connects the first plane 21 and the second plane 22. The connection surface 23 smoothly connects to the upper end of the first plane 21 and the upper end of the second plane 22. The connection surface 23 is a curved surface that curves upward. In this embodiment, the connection surface 23 is arc-shaped in a side view seen from the second direction. The vertex 200 of the ceiling 20 is formed by the vertex of the connection surface 23.

[0024] In this embodiment, the second plane 22 is longer than the first plane 21. The second plane 22 has a main body 22a located above the lower end 21a of the first plane 21 and an extension 22b located below the lower end 21a of the first plane 21. Therefore, the ceiling 20 of this embodiment has an asymmetric shape with respect to the vertex 200 of the ceiling 20 in the first direction. Specifically, the ceiling 20 is asymmetric with respect to a vertical line passing through the vertex 200.

[0025] As shown in Fig. 3, the first flat surface portion 20a including the first flat surface 21 is composed of a plurality of first bases 31 and a plurality of first ceiling panels 32. In this embodiment, the first bases 31 are composed of runners extending linearly. In this embodiment, the first ceiling panels 32 are composed of gypsum boards.

[0026] The first lower surface 31a of the first base 31 is a plane that slopes in the first direction so that the height increases as it approaches the second plane 22. In this embodiment, the first base 31 extends to the ridge beam 12. The upper end of the first base 31 is connected to the ridge beam 12.

[0027] 4, the plurality of first bases 31 are arranged side by side in the second direction. In this embodiment, the first bases 31 are arranged side by side in the direction in which the ridge beam 12 extends.

[0028] As shown in FIG. 3 , the first ceiling panel 32 is disposed along the first lower surface 31a of the first base 31. Therefore, the first ceiling panel 32 is inclined so that its height increases in the first direction as it approaches the second plane 22. Note that the first ceiling panel 32 is not disposed on a portion of the first lower surface 31a of the first base 31 that contacts a third base 35 (described later). In this embodiment, the width of the first ceiling panel 32 in the second direction is approximately twice the spacing between the first bases 31 in the second direction. Both end portions and the center portion of the first ceiling panel 32 in the second direction overlap the first base 31 in the up-down direction.

[0029] The second flat surface portion 20b including the second flat surface 22 is composed of a plurality of second bases 33 and a plurality of second ceiling panels 34. In this embodiment, the second bases 33 are composed of runners that extend linearly. In this embodiment, the second ceiling panels 34 are composed of gypsum boards.

[0030] The second lower surface 33a of the second base 33 is a plane that slopes in height in the first direction toward the first plane 21. The second base 33 in this embodiment extends to the ridge beam 12. The upper end of the second base 33 is connected to the ridge beam 12.

[0031] As shown by the dashed dotted line in Fig. 4, the multiple second bases 33 are arranged side by side in the second direction. In this embodiment, the second bases 33 are arranged side by side in the direction in which the ridge beam 12 extends. The intervals at which the second bases 33 are arranged in the second direction are the same as the intervals at which the first bases 31 are arranged in the second direction. The first bases 31 and the second bases 33 are arranged in the same position in the second direction.

[0032] As shown in FIG. 3 , the second ceiling panel 34 is disposed along the second lower surface 33a of the second base 33. Therefore, the second ceiling panel 34 is inclined so that its height increases in the first direction as it approaches the first plane 21. Note that the second ceiling panel 34 is not disposed on a portion of the second lower surface 33a of the second base 33 that contacts a third base 35 (described later). In this embodiment, the width of the second ceiling panel 34 in the second direction is approximately twice the spacing between the second bases 33 in the second direction. Both end portions and the center portion of the second ceiling panel 34 in the second direction overlap the second base 33 in the up-down direction.

[0033] The connection surface portion 20c, including the connection surface 23, is composed of a plurality of third bases 35 and a plurality of third ceiling panels 36. The third base 35 of this embodiment is composed of a wooden or metal member. The third base 35 of this embodiment is approximately triangular. The third lower surface 35a of the third base 35 is a curved surface that curves upward. The third ceiling panel 36 of this embodiment is composed of gypsum board. The gypsum board that constitutes the third ceiling panel 36 is flexible.

[0034] As shown by the dashed lines in Fig. 4, the multiple third bases 35 are arranged side by side in the second direction. In this embodiment, the third bases 35 are arranged side by side in the direction in which the ridge beam 12 extends. The interval at which the third bases 35 are arranged in the second direction is approximately half the interval at which the first bases 31 and the second bases 33 are arranged in the second direction. The third bases 35 are arranged in the same position as the first bases 31 and the second bases 33 in the second direction.

[0035] As shown in FIG. 3 , the third base 35 is located below the first base 31 and the second base 33. The third base 35 is in contact with a portion of the first lower surface 31a of the first base 31 and a portion of the second lower surface 33a of the second base 33. A plurality of grooves 12b are provided on the lower surface 12a of the ridge beam 12. Each groove 12b extends along the first direction. The plurality of grooves 12b are arranged at intervals in the direction in which the ridge beam 12 extends, i.e., in the second direction. The third base 35 is inserted into the grooves 12b of the ridge beam 12. The third base 35 is connected to the ridge beam 12. In this embodiment, the third lower surface 35a of the third base 35 is located below the lower surface 12a of the ridge beam 12.

[0036] In this embodiment, the plurality of third bases 35 are arranged so that the vertices of the third lower surfaces 35a of the respective third bases 35 overlap with the ridge beam 12 in the vertical direction. Therefore, the plurality of third bases 35 are arranged so that the vertices of the third lower surfaces 35a of the respective third bases 35 are aligned in a straight line.

[0037] The third ceiling panel 36 is disposed along the third lower surface 35a of the third base 35. Therefore, the third ceiling panel 36 is curved upward. 4, in this embodiment, the width of the third ceiling panel 36 in the second direction is approximately the same as the spacing between the third bases 35 in the second direction. Both end portions of the third ceiling panel 36 in the second direction overlap the third bases 35 in the vertical direction.

[0038] As shown in Fig. 3, in this embodiment, a plastering material layer 37 is provided on the underside of the first ceiling panel 32, the underside of the second ceiling panel 34, and the underside of the third ceiling panel 36. Note that the plastering material layer 37 is not shown in Fig. 4.

[0039] <First and second areas> As shown in FIGS. 1 and 2, the interior space 11 has a first area 11a and a second area 11b. In this embodiment, the first area 11a is used as a bedroom. The second area 11b is used as a passageway adjacent to the bedroom. The first area 11a is located below the first plane 21, the connecting surface 23, and the main body 22a of the second plane 22 of the ceiling 20. Therefore, the first area 11a is a region symmetrical with respect to the vertex 200 of the ceiling 20 in the first direction. Specifically, the first area 11a is symmetrical with respect to a vertical line passing through the vertex 200. The second area 11b is located below the extension 22b of the second plane 22 of the ceiling 20. The second area 11b is aligned with the first area 11a in the first direction.

[0040] <Wall> The building 10 has a partition wall 13 as a wall portion. The partition wall 13 extends along a first direction. The partition wall 13 divides the interior space 11 in a second direction. The partition wall 13 is provided below the first plane 21, the connecting surface 23, and the main body portion 22a of the second plane 22. The partition wall 13 is not provided below the extension portion 22b of the second plane 22. Therefore, the partition wall 13 is symmetrical with respect to the vertex 200 of the ceiling 20 in the first direction. Specifically, the partition wall 13 is symmetrical with respect to a vertical line passing through the vertex 200. The partition wall 13 is aligned with the first region 11a in the second direction.

[0041] The building 10 includes a first wall portion 14 that is located on the first plane 21 side in the first direction and extends along the second direction. In this embodiment, the first wall portion 14 constitutes an exterior wall on the first plane 21 side in the first direction. A window 14a is provided in an upper portion of the first wall portion 14.

[0042] The building 10 includes a second wall portion 15 that is located on the second plane 22 side in the first direction and extends along the second direction. In this embodiment, the second wall portion 15 forms an exterior wall on the second plane 22 side in the first direction.

[0043] [Operation of this embodiment] The operation of this embodiment will be described. The ceiling 20 has a first plane 21, a second plane 22, and a connecting surface 23 connecting the first plane 21 and the second plane 22. The first plane 21 is inclined so that its height increases as it approaches the second plane 22 in the first direction. The second plane 22 is inclined so that its height increases as it approaches the first plane 21 in the first direction. The connecting surface 23 smoothly connects to the upper end of the first plane 21 and the upper end of the second plane 22. The connecting surface 23 is curved upward.

[0044] According to this configuration, the slope of the ceiling 20 changes continuously in the first direction. This improves the aesthetic appearance of the ceiling 20. Furthermore, since no corners are formed on the ceiling 20 due to the connection of flat surfaces, the ceiling 20 gives a soft impression. Therefore, the interior space 11 becomes an enveloping space. Furthermore, the light within the interior space 11 can spread freely along the ceiling 20. Depending on the light entering the interior space 11 from the window 14a, a gradation of shadows is formed on the ceiling 20.

[0045] The first flat surface portion 20a including the first flat surface 21 is composed of a plurality of first bases 31 and a first ceiling panel 32. The first lower surface 31a of the first base 31 is a plane that slopes so that the height increases as it approaches the second flat surface 22 in the first direction. The plurality of first bases 31 are arranged side by side in the second direction. The first ceiling panel 32 is arranged along the first lower surface 31a of the first base 31.

[0046] The second plane portion 20b, which includes the second plane 22, is composed of a plurality of second bases 33 and a second ceiling panel 34. The second lower surface 33a of the second base 33 is a plane that slopes so that the height increases as it approaches the first plane 21 in the first direction. The plurality of second bases 33 are arranged side by side in the second direction. The second ceiling panel 34 is arranged along the second lower surface 33a of the second base 33.

[0047] The connection surface portion 20c, including the connection surface 23, is composed of a plurality of third bases 35 and a third ceiling panel 36. The third lower surface 35a of the third base 35 is a curved surface that curves upward. The plurality of third bases 35 are arranged side by side in the second direction. The third ceiling panel 36 is arranged along the third lower surface 35a of the third base 35.

[0048] According to this configuration, a highly accurate curved surface can be formed by placing the third ceiling panel 36 along the third lower surface 35a of the third base 35 without having to prepare a curved third ceiling panel 36.

[0049] [Effects of this embodiment] The effects of this embodiment will be described. (1) The ceiling 20 has a first plane 21, a second plane 22, and a connecting surface 23 connecting the first plane 21 and the second plane 22. The connecting surface 23 is smoothly connected to the upper end of the first plane 21 and the upper end of the second plane 22. The connecting surface 23 is a curved surface that curves upward. With this configuration, the slope of the ceiling 20 changes continuously in the first direction. This improves the aesthetic appearance of the ceiling 20. Furthermore, since no corners are created on the ceiling 20 due to the connection between the planes, the ceiling 20 gives a soft impression. Therefore, the interior space 11 becomes a space with a feeling of being enveloped. Furthermore, light within the interior space 11 can spread freely along the ceiling 20.

[0050] The connection surface portion 20c including the connection surface 23 is configured by a third base 35, whose third lower surface 35a is a curved surface that curves upward, and a third ceiling panel 36 that is arranged along the third lower surface 35a of the third base 35. With this configuration, even without preparing a curved third ceiling panel 36, a highly accurate curved surface can be formed by arranging the third ceiling panel 36 along the third lower surface 35a of the third base 35.

[0051] (2) The building 10 has a ridge beam 12 that extends along the second direction. Therefore, by using the ridge beam 12 as a guide and arranging the third bases 35 in the direction in which the ridge beam 12 extends, the third bases 35 are arranged in the second direction. This makes it easier to arrange the third bases 35.

[0052] Furthermore, each third base 35 is arranged so that the apex of the third lower surface 35a overlaps the ridge beam 12 in the vertical direction. This allows the multiple third bases 35 to be arranged so that the apexes of the third lower surfaces 35a are aligned in a straight line. This makes it possible to suppress misalignment of the third bases 35 in the first direction.

[0053] (3) The upper end of the first base 31 and the upper end of the second base 33 each extend toward the ridge beam 12 and are connected to the ridge beam 12. In the second direction, the first base 31, the second base 33, and the third base 35 are arranged in the same position. The third base 35 is in contact with the first lower surface 31a of the first base 31 and the second lower surface 33a of the second base 33. This configuration allows the third base 35 to be stably arranged.

[0054] (4) A plastering material layer 37 is provided on the underside of the first ceiling panel 32, the underside of the second ceiling panel 34, and the underside of the third ceiling panel 36. With this configuration, the boundary between the first ceiling panel 32 and the third ceiling panel 36 and the boundary between the second ceiling panel 34 and the third ceiling panel 36 are covered with the plastering material layer 37, further improving the aesthetic appearance of the ceiling 20.

[0055] (5) The connecting surface 23 has an arc shape in a side view seen from the second direction, which further improves the aesthetic appearance of the ceiling 20. (6) The building 10 has a partition wall 13 extending along the first direction. The second plane 22 has a main body 22a located above the lower end 21a of the first plane 21 and an extension 22b located below the lower end 21a of the first plane 21. The partition wall 13 is located below the first plane 21, the connecting surface 23, and the main body 22a of the second plane 22. The indoor space 11 has a first region 11a located below the first plane 21, the connecting surface 23, and the main body 22a of the second plane 22, and a second region 11b located below the extension 22b of the second plane 22.

[0056] According to this configuration, the ceiling 20 has an asymmetric shape with respect to the vertex 200 of the ceiling 20 in the first direction. Therefore, the entire interior space 11 is an asymmetric space with respect to the vertex 200 of the ceiling 20 in the first direction. On the other hand, the first region 11a is an area that is symmetric with respect to the vertex 200 of the ceiling 20 in the first direction. By providing the partition wall 13 in the first region 11a, the partition wall 13 has a symmetric shape with respect to the vertex 200 of the ceiling 20 in the first direction, which emphasizes that the first region 11a is a symmetrical area when the interior space 11 is viewed from the second direction. By providing the symmetrical first region 11a in the asymmetric interior space 11 in this way, the design of the interior space 11 is improved.

[0057] Furthermore, since the ceiling height of the second area 11b is lower than that of the first area 11a, people in the indoor space 11 tend to feel a sense of openness when moving from the second area 11b to the first area 11a.

[0058] (7) The building 10 has a first wall 14 located on the first plane 21 side in the first direction. A window 14a is provided in the upper part of the first wall 14. This makes it easier for light to enter the interior space 11 through the window 14a. Furthermore, compared to when the window 14a is provided in the second wall 15, the light that enters the interior space 11 is more likely to spread along the ceiling 20.

[0059] <Example of change> The above-described embodiment is an example of a form that the building 10 can take, and is not intended to limit the form. The building 10 can take a form different from the form exemplified in the above-described embodiment. Examples of such a form include a form in which part of the configuration of the embodiment is replaced, modified, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0060] · Building 10 is not limited to a two-story detached house. The indoor space 11 may be provided on the first floor or on the third or higher floor of the building 10. The ridge beam 12 does not have to extend along the second direction. In this case, the third base 35 may be arranged in the second direction using a guide member separate from the ridge beam 12 that extends along the second direction as a guide.

[0061] In the ridge beam 12 of the above embodiment, the portion supporting the gradient beam and the portion having the groove 12b into which the third base 35 is inserted are integral, but the portion supporting the gradient beam and the portion having the groove 12b into which the third base 35 is inserted may be separate.

[0062] The first base 31 and the second base 33 do not have to extend to the ridge beam 12. Each of the multiple third bases 35 does not have to be positioned so that the apex of the third lower surface 35a overlaps with the ridge beam 12 in the vertical direction.

[0063] The first substrate 31, the second substrate 33, and the third substrate 35 do not have to be arranged in the same position in the second direction. If the third substrate 35 is arranged in a different position from the first substrate 31 and the second substrate 33 in the second direction, the third substrate 35 will not contact a part of the first lower surface 31a of the first substrate 31 or a part of the second lower surface 33a of the second substrate 33. This example also achieves at least the effect (1) above.

[0064] The third lower surface 35a of the third base 35 may be continuous with the lower surface 12a of the ridge beam 12. In this case, the third ceiling panel 36 is positioned so as to contact not only the third lower surface 35a of the third base 35 but also the lower surface 12a of the ridge beam 12.

[0065] The first ceiling panel 32, the second ceiling panel 34, and the third ceiling panel 36 may be made of a material other than gypsum board.
