Description

[Technical field]

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

[0002] 2. Description of the Related Art A conventionally known building is a house shown in, for example, Patent Document 1. This type of house has a gabled roof. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-57557 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, if you want to deepen the eaves of a house like the one described above, you can simply extend the gable roof. However, because a gable roof is inclined, if it is extended too long, the eaves height becomes too low, so there is a limit to the eaves height. For this reason, the gable roof cannot be extended too long, so there is a problem that the eaves cannot be made too deep.

[0005] Furthermore, these problems are not limited to buildings with gabled roofs, but are also common to buildings with sloped roofs other than gabled roofs. [Means for solving the problem]

[0006] (1) A building that solves the above problem comprises an exterior wall, a first roof having a first inclined portion that slopes downward toward the exterior wall, and a room provided below the first roof and having a first ceiling surface that slopes downward toward the exterior wall, wherein the exterior wall is provided with a flat roof that extends outward, and the flat roof is positioned at a height equal to or higher than the lower end of the first ceiling surface of the exterior wall.

[0007] Normally, to deepen the eaves, it is sufficient to extend the first inclined portion of the first roof. However, if the first inclined portion is extended too far, the eaves height becomes too low, so there is a limit to the eaves height. For this reason, the first inclined portion cannot be extended too far, and the eaves cannot be made too deep. In this regard, with this configuration, since the flat roof extends outward from the exterior wall, the eaves height changes very little even if the extension length of the flat roof is increased. Therefore, the eaves can be made sufficiently deep.

[0008] (2) In the building described in (1) above, the flat roof is positioned so as to be adjacent to the lower end of the first ceiling surface of the exterior wall. With this configuration, the underside of the flat roof and the first ceiling surface are connected in a nearly continuous state, which allows for a natural connection between the space under the eaves of the flat roof and the space inside the room.

[0009] (3) In the building of (1) or (2) above, the first roof has a second inclined portion that slopes downward toward the opposite side of the first inclined portion at an angle equal to that of the first inclined portion, the first inclined portion has a shorter length in the inclination direction than the second inclined portion, and the flat roof partially overlaps with the first inclined portion in a plan view. According to this configuration, an eaves space of the first inclined portion is formed above the flat roof, which is narrower than the eaves space of the flat roof, thereby contributing to improving the design of the exterior.

[0010] (4) In the building described in (3) above, the room has a first ceiling surface that runs along the first inclined portion and a second ceiling surface that runs along the second inclined portion, a first boundary line that is the boundary between the first ceiling surface and the second ceiling surface is parallel to a second boundary line that is the boundary between the first inclined portion and the second inclined portion, and a height position is located between the second boundary line and the lower end of the second inclined portion. This configuration creates a sloped ceiling in the room, making the space feel larger and more open.

[0011] (5) In the building of (4) above, the extension length of the flat roof from the exterior wall is longer than half the length from the first boundary line to the lower end of the first ceiling surface. With this configuration, the extension length of the flat roof from the exterior wall is ensured sufficiently, so that sufficient space under the eaves of the flat roof can be secured.

[0012] (6) In the building of (4) or (5) above, a second roof is provided having a third inclined portion inclined along the first inclined portion and a fourth inclined portion inclined along the second inclined portion, and the second roof is positioned at a position offset from the first roof in a direction along the second boundary line. With this configuration, the first roof and the second roof are aligned in a direction along the ridge of the first roof, which contributes to improving the design.

[0013] (7) In the building of (6) above, the fourth inclined portion is connected so as to be continuous with the second inclined portion.

[0014] According to this configuration, the fourth inclined portion is connected so as to be continuous with the second inclined portion, which can contribute to improving the design. Effect of the Invention

[0015] The buildings of the present disclosure can have sufficiently deep eaves. [Brief description of the drawings]

[0017] Hereinafter, one embodiment of a building will be described with reference to the drawings. <Building 11> As shown in Figs. 1 to 3, the building 11 is, for example, a one-story house built on the ground. The building 11 includes a box-shaped main body 12 having a plurality of side walls, and a first roof 13 and a second roof 14 arranged on the main body 12. The main body 12 has a substantially rectangular shape in a plan view. As an example, both the first roof 13 and the second roof 14 are gable roofs. In the following description, the long side direction of the main body 12 is defined as the X direction, and the short side direction of the main body 12 is defined as the Y direction.

[0018] <Main body 12> 1 to 3, the main body 12 includes a first main body 15 constituting one side in the X direction and a second main body 16 constituting the other side in the X direction. The first main body 15 and the second main body 16 are disposed adjacent to each other in the X direction and are connected so that their interiors communicate with each other. The width of the second main body 16 in the Y direction is wider than the width of the first main body 15 in the Y direction.

[0019] One side wall in the Y direction of the first main body portion 15 is an outer wall 17. The outer wall 17 of the first main body portion 15 is located more inward in the Y direction than one side wall in the Y direction of the second main body portion 16. A rectangular plate-shaped wall member 18 is erected at an adjacent position on the opposite side of the first main body portion 15 from the second main body portion 16 side so as to face the first main body portion 15 in the X direction.

[0020] 1 and 3, a sliding sash 19 is provided on the outer wall 17 of the first main body portion 15. A flat roof 20 extending almost horizontally outward in the Y direction is provided at a position above the sash 19 on the outer wall 17 of the first main body portion 15. The flat roof 20 is provided on the entire outer wall 17 of the first main body portion 15 in the X direction and on a part of the side surface of the first main body portion 15 facing the wall member 18. The flat roof 20 is approximately L-shaped in a plan view.

[0021] <First Roof 13> As shown in Figs. 1 to 3, the first roof 13 is provided on the first main body portion 15. The first roof 13 has a first inclined portion 21 that is inclined downward toward the outer wall 17, and a second inclined portion 22 that is inclined downward toward the opposite side of the first inclined portion 21 in the Y direction at an angle equal to that of the first inclined portion 21. The upper ends of the first inclined portion 21 and the second inclined portion 22 are connected to each other. The boundary between the first inclined portion 21 and the second inclined portion 22 is a second boundary line 23 that extends in the X direction. Therefore, the ridge of the first roof 13 extends in the X direction.

[0022] The first inclined portion 21 has a shorter length in the inclination direction than the second inclined portion 22. The lower end portions of the first inclined portion 21 and the second inclined portion 22 protrude outward in the Y direction beyond the first main body portion 15. The lower end portion of the first inclined portion 21 overlaps with a portion of the flat roof 20 in a plan view. That is, the flat roof 20 partially overlaps with the first inclined portion 21 in a plan view.

[0023] <Second Roof 14> As shown in Figs. 1 to 3, the second roof 14 is provided on the second main body portion 16. The second roof 14 has a third inclined portion 24 inclined along the first inclined portion 21, and a fourth inclined portion 25 inclined along the second inclined portion 22. The second roof 14 is disposed at a position shifted from the first roof 13 in the direction along the second boundary line 23. In other words, the second roof 14 is disposed adjacent to the first roof 13 in the X direction.

[0024] The upper ends of the third inclined portion 24 and the fourth inclined portion 25 are connected to each other. The ridge of the second roof 14 extends in the X direction. The ridge of the second roof 14 is located closer to the flat roof 20 than the ridge of the first roof 13 in the Y direction, and is located at a higher position than the ridge of the first roof 13. The lower ends of the third inclined portion 24 and the fourth inclined portion 25 protrude outward from the second main body portion 16 in the Y direction. The fourth inclined portion 25 is connected to the second inclined portion 22 so as to be continuous in the X direction.

[0025] <Internal structure of Building 11> As shown in Figures 4 and 5, a room 26 is provided inside the first main body portion 15 below the first roof 13. The room 26 has an open-ceiling structure that reaches up to the first roof 13. The room 26 has a first ceiling surface 27 along the first inclined portion 21 and a second ceiling surface 28 along the second inclined portion 22. The first ceiling surface 27 is inclined so as to descend toward the exterior wall 17. The second ceiling surface 28 is inclined at an angle equal to that of the first ceiling surface 27 so as to descend toward the opposite side to the exterior wall 17 side.

[0026] The upper ends of the first ceiling surface 27 and the second ceiling surface 28 are connected to each other. The boundary between the first ceiling surface 27 and the second ceiling surface 28 is a first boundary line 29 extending in the X direction. The first boundary line 29 is parallel to the second boundary line 23 which is the boundary between the first inclined portion 21 and the second inclined portion 22. The height position of the first boundary line 29 is located between the second boundary line 23 and the lower end of the second inclined portion 22.

[0027] The second boundary line 23 is located at a position closer to the outer wall 17 in the Y direction than the first boundary line 29. That is, the first boundary line 29 and the second boundary line 23 are located at different positions in the Y direction so as not to overlap each other in the vertical direction.

[0028] <Flat Roof 20> 5 and 6, the flat roof 20 is disposed at a position equal to or higher than the lower end of the first ceiling surface 27 of the exterior wall 17. As an example, the flat roof 20 of this embodiment is disposed so as to be adjacent to the lower end of the first ceiling surface 27 of the exterior wall 17. In other words, the flat roof 20 is disposed so that its lower surface is slightly higher than the lower end of the first ceiling surface 27. The extension length A of the flat roof 20 from the exterior wall 17 in the Y direction is longer than half the length B from the first boundary line 29 to the lower end of the first ceiling surface 27.

[0029] A step surface 30, which is a vertical surface, is formed between the underside of the flat roof 20 and the first ceiling surface 27. The sash 19 provided on the exterior wall 17 includes a sash frame 31 and a glass screen 32. The glass screen 32 is slidably supported by the sash frame 31. An upper portion of a screen frame 33 of the glass screen 32 faces the step surface 30 in the Y direction. For this reason, the upper portion of the screen frame 33 of the glass screen 32 is difficult to see from inside the room 26.

[0030] <Operation of the embodiment> In the building 11, the flat roof 20 allows the eaves to be deep enough while still ensuring sufficient eaves height. This creates an intermediate area between the indoors and outdoors, as the room 26 (indoor space) with an open-feeling sloped ceiling is continuous with the deep eaves space created by the flat roof 20. This allows outdoor life scenes to extend indoors, while indoor life scenes to the outdoors. As a result, it becomes possible to realize a variety of rich lifestyles.

[0031] <Effects of the embodiment> According to the embodiment described above in detail, the following effects are achieved. (1) Building 11 comprises an exterior wall 17, a first roof 13 having a first inclined portion 21 that slopes downward toward exterior wall 17, and a room 26 provided below first roof 13 and having a first ceiling surface 27 that slopes downward toward exterior wall 17. A flat roof 20 extending outward is provided on exterior wall 17. Flat roof 20 is positioned at a height equal to or higher than the lower end of first ceiling surface 27 on exterior wall 17.

[0032] Normally, to deepen the eaves, it is sufficient to extend the first inclined portion 21 of the first roof 13. However, if the first inclined portion 21 is extended too far, the eaves height becomes too low, so there is a limit to the eaves height. For this reason, the first inclined portion 21 cannot be extended too far, and the eaves cannot be made too deep. In this regard, with this configuration, since the flat roof 20 extends outward from the exterior wall 17, even if the extension length A of the flat roof 20 is increased, there is almost no change in the eaves height. Therefore, the eaves can be made sufficiently deep.

[0033] (2) In the building 11, the flat roof 20 is positioned so as to be adjacent to the lower end of the first ceiling surface 27 of the exterior wall 17. According to this configuration, the underside of the flat roof 20 and the first ceiling surface 27 are connected in a nearly continuous state. Therefore, the space under the eaves of the flat roof 20 and the space inside the room 26 can be connected in a natural way.

[0034] (3) In the building 11, the first roof 13 has a second inclined portion 22 that slopes downward toward the opposite side to the first inclined portion 21 at an angle equal to that of the first inclined portion 21. The first inclined portion 21 has a shorter length in the inclination direction than the second inclined portion 22. The flat roof 20 partially overlaps with the first inclined portion 21 in a plan view.

[0035] According to this configuration, an eaves space of the first inclined portion 21 that is narrower than the eaves space of the flat roof 20 is formed above the flat roof 20, which contributes to improving the design of the exterior. (4) In the building 11, the room 26 has a first ceiling surface 27 along the first inclined portion 21 and a second ceiling surface 28 along the second inclined portion 22. A first boundary line 29, which is the boundary between the first ceiling surface 27 and the second ceiling surface 28, is parallel to a second boundary line 23, which is the boundary between the first inclined portion 21 and the second inclined portion 22, and is located at a height position between the second boundary line 23 and the lower end of the second inclined portion 22.

[0036] With this configuration, the ceiling of room 26 becomes a sloped ceiling, making the space feel larger, creating a more open feeling. (5) In the building 11 , the extension length A of the flat roof 20 from the exterior wall 17 is longer than half the length B from the first boundary line 29 to the lower end of the first ceiling surface 27 .

[0037] According to this configuration, the extension length A of the flat roof 20 from the exterior wall 17 is sufficiently secured, so that the eaves space under the flat roof 20 can be sufficiently secured. (6) Building 11 has second roof 14 having third inclined portion 24 inclined along first inclined portion 21 and fourth inclined portion 25 inclined along second inclined portion 22. Second roof 14 is positioned offset from first roof 13 in a direction along second boundary line 23.

[0038] With this configuration, first roof 13 and second roof 14 are aligned in a direction along the ridge of first roof 13, which contributes to improving the design. (7) In the building 11, the fourth inclined portion 25 is connected so as to be continuous with the second inclined portion 22.

[0039] According to this configuration, the fourth inclined portion 25 is connected to the second inclined portion 22 so as to be continuous therewith, which can contribute to improving the design. <Modification> The above embodiment is an example of a form that the building 11 can take, and is not intended to limit the form. The building 11 can take a form different from the form exemplified in the above embodiment. Examples of such a form include a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0040] 7, the first roof 13 may be configured as, for example, a sloping roof. In this case, the first roof 13 has a first inclined portion 21 and does not have a second inclined portion 22. As shown in FIG. 7, the second ceiling surface 28 may be a horizontal surface.

[0041] By omitting the step surface 30, the lower surface of the flat roof 20 and the first ceiling surface 27 may be connected so as to be continuous. The fourth inclined portion 25 does not necessarily have to be connected to the second inclined portion 22 so as to be continuous therewith.

[0042] The second roof 14 and the second main body portion 16 may be omitted. The second roof 14 does not necessarily have to be positioned at a position offset from the first roof 13 in the direction along the second boundary line 23 .

[0043] The extension length A of the flat roof 20 from the exterior wall 17 does not necessarily have to be longer than half the length B from the first boundary line 29 to the lower end of the first ceiling surface 27. The first boundary line 29 does not necessarily have to be parallel to the second boundary line 23 .

[0044] The height position of the first boundary line 29 does not necessarily have to be located between the second boundary line 23 and the lower end of the second inclined portion 22 . The first inclined portion 21 does not necessarily have to be shorter in length in the inclined direction than the second inclined portion 22 .

[0045] The flat roof 20 does not necessarily have to partially overlap with the first inclined portion 21 in a plan view. In other words, the first inclined portion 21 does not necessarily have to protrude outward beyond the exterior wall 17 in the Y direction.

[0046] The flat roof 20 does not necessarily have to be positioned adjacent to the lower end of the first ceiling surface 27 of the exterior wall 17. The height at which the flat roof 20 is placed may be changed as appropriate, so long as it is placed at a position equal to or higher than the height of the lower end of the first ceiling surface 27 of the exterior wall 17. In this case, it is preferable to place the flat roof 20 so as not to come into contact with the first roof 13.
