Description

[Technical Field]

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

[0002] BACKGROUND ART A known example of a conventional building is the building shown in Patent Document 1. Such a building has an open-ceiling living space with a sloped ceiling inside. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-104977 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the living space of the building described above has no pillars and is an open-ceiling structure with a sloped ceiling, so it gives a sense of openness but does not give a sense of closure. Therefore, a living space that can give both a sense of openness and a sense of closure is desired. [Means for solving the problem]

[0005] (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, wherein the room comprises a first room that has an open-ceiling structure that extends up to the first roof and has a first ceiling surface that follows the first inclined portion, and a second room that is connected to the first room and has a low ceiling surface that is lower than the first ceiling surface.

[0006] With this configuration, the room is constructed by connecting a first room with a relatively large open-ceiling structure that gives it an open feeling, and a second room with a relatively small space and a lower ceiling than the first room that gives it a closed-in feeling, creating a space that gives it both an open feeling and a closed-in feeling.

[0007] (2) In the building described in (1) above, the low ceiling surface is configured flat. This configuration makes the second room a more secluded and relaxing space.

[0008] (3) In the building of (1) or (2) above, the first roof has a second inclined portion that slopes downward toward the opposite side to the first inclined portion, the exterior wall has a first exterior wall that intersects with the first inclined portion and a second exterior wall that intersects with the second inclined portion and faces the first exterior wall, the room is arranged between the first exterior wall and the second exterior wall, the second exterior wall has a third exterior wall and a fourth exterior wall that is arranged closer to the first exterior wall than the third exterior wall, and the second room is arranged between the first exterior wall and the fourth exterior wall.

[0009] With this configuration, the width of the second chamber in the opposing direction between the first outer wall and the second outer wall is narrower than the width of the first chamber in the opposing direction between the first outer wall and the second outer wall, thereby further enhancing the sense of enclosure in the second chamber.

[0010] (4) In the building of (3) above, a shielding portion protruding from the inner surface of the first outer wall is provided near the boundary between the first room and the second room on the inner surface of the first outer wall. According to this configuration, the shielding portion can hide part of the second chamber.

[0011] (5) In the building described in (4) above, the first exterior wall has a first window portion provided in the first room and a second window portion provided in the second room, and the shielding portion is positioned so that the second window portion of the second room cannot be seen from the first room.

[0012] With this configuration, when looking at the second room from the first room, the second window of the second room cannot be seen, but the light shining into the second room from the second window can be seen. This makes it possible to more symbolically display the light shining into the second room from the second window.

[0013] (6) In the building of (4) or (5) above, the first exterior wall has a recess that is recessed outward, and the recess is positioned adjacent to the shielding portion in the first room.

[0014] With this configuration, the recess has light-blocking properties, so the area adjacent to the shielding part in the first room can be darkened. Therefore, in the first room, the darkened area adjacent to the shielding part and the area where light entering through the first window reaches can be perceived as light and dark. In addition, shelves or the like can be placed in the recess.

[0015] (7) In any one of the buildings (3) to (6) 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 boundary line between the first inclined portion and the second inclined portion. 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.

[0016] (8) In the building described in (7) above, the first roof has a first truss provided above the second room and a sloped structural section provided above the first room, the second roof has a second truss, and the sloped structural section is arranged between the first truss and the second truss and is connected to the first truss and the second truss. According to this configuration, the inclined structural portion, which has a relatively low strength, can be reinforced by the first and second trusses, which have a relatively high strength.

[0017] (9) In the building of (8) above, the inclined structural portion has a plurality of cross members extending horizontally in a direction intersecting the inclination direction of the first inclined portion, the plurality of cross members being connected to each other by inclined connecting members extending in the inclination direction of the first inclined portion and being supported by columns at only both ends, the second truss has a plurality of beams extending vertically and horizontal connecting members extending horizontally to connect the plurality of beams, and the number of the cross members per unit length in the inclination direction of the first inclined portion of the first roof is greater than the number of the horizontal connecting members per unit length in the inclination direction of the third inclined portion of the second roof.

[0018] According to this configuration, the density of the cross members is greater than the density of the horizontal connecting members, so the strength of the first roof, which is weaker than the second roof, can be made closer to the strength of the second roof. [Effects of the Invention]

[0019] The building of the present disclosure can create a space that gives both a sense of openness and a sense of seclusion. [Brief explanation of the drawings]

[0021] Hereinafter, an embodiment of a building will be described with reference to the drawings. <Building 11> As shown in Figures 1 and 2, building 11 is, for example, a one-story house built on the ground. Building 11 includes a box-shaped main body 12 having multiple side walls, and a first roof 13 and a second roof 14 disposed on main body 12. Main body 12 has a substantially rectangular shape in a plan view. As an example, first roof 13 and second roof 14 are both gable roofs. In the following description, the long side direction of main body 12 is defined as the X direction, and the short side direction of main body 12 is defined as the Y direction.

[0022] <Main body 12> 1 and 2, the main body 12 includes a first main body 15 that forms one side in the X direction and a second main body 16 that forms 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.

[0023] The side walls on both sides of the first main body portion 15 in the Y direction are outer walls 17. Of the two outer walls 17 of the first main body portion 15, one is a first outer wall 18 and the other is a second outer wall 19. The first outer wall 18 and the second outer wall 19 face each other in the Y direction.

[0024] The second outer wall 19 of the first main body portion 15 is located more inward in the Y direction than the side wall of the second main body portion 16 on the same side as the second outer wall 19 in the Y direction. A rectangular plate-shaped wall member 20 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.

[0025] A flat roof 21 extending substantially horizontally outward in the Y direction is provided on the upper part of the second outer wall 19 of the first main body portion 15. The flat roof 21 is provided on the entire second outer wall 19 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 20. The flat roof 21 is substantially L-shaped in a plan view.

[0026] <First Roof 13> As shown in Figures 1 to 3, first roof 13 is provided on first main body portion 15. First roof 13 has a first inclined portion 22 that slopes downward toward first outer wall 18, and a second inclined portion 23 that slopes downward toward second outer wall 19 at the same angle as first inclined portion 22. Second inclined portion 23 slopes downward toward the opposite side to first inclined portion 22. The upper ends of first inclined portion 22 and second inclined portion 23 are connected to each other.

[0027] The first inclined portion 22 intersects with the first outer wall 18. The second inclined portion 23 intersects with the second outer wall 19. A boundary line 24 between the first inclined portion 22 and the second inclined portion 23 extends in the X direction. Therefore, the ridge of the first roof 13 extends in the X direction. The second inclined portion 23 has a shorter length in the inclination direction than the first inclined portion 22. The lower ends of the first inclined portion 22 and the second inclined portion 23 protrude outward in the Y direction beyond the first main body portion 15.

[0028] <Second Roof 14> As shown in FIGS. 1 to 3, second roof 14 is provided on second main body portion 16. Second roof 14 has third inclined portion 25 inclined along first inclined portion 22 and fourth inclined portion 26 inclined along second inclined portion 23. Second roof 14 is disposed at a position offset from first roof 13 in a direction along boundary line 24. In other words, second roof 14 is disposed adjacent to first roof 13 in the X direction.

[0029] The upper ends of the third inclined portion 25 and the fourth inclined portion 26 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 21 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 25 and the fourth inclined portion 26 protrude outward in the Y direction beyond the second main body portion 16. The third inclined portion 25 is connected to the first inclined portion 22 so as to be continuous in the X direction.

[0030] <Internal structure of Building 11> As shown in Figures 3 to 5, a room 27 is provided inside the first main body portion 15 below the first roof 13. The room 27 is arranged between the first outer wall 18 and the second outer wall 19. The room 27 includes a first room 28 having an open-ceiling structure extending up to the first roof 13, and a second room 29 adjacent to and connected to the first room 28 on the side opposite to the second main body portion 16 side. The second room 29 is smaller than the first room 28.

[0031] The first chamber 28 has a first ceiling surface 30 that follows the first inclined portion 22 and a second ceiling surface 31 that follows the second inclined portion 23. The first ceiling surface 30 is inclined so as to descend toward the first outer wall 18. The second ceiling surface 31 is inclined at an angle equal to that of the first ceiling surface 30 so as to descend toward the side opposite the first outer wall 18. In other words, the second ceiling surface 31 is inclined so as to descend toward the second outer wall 19.

[0032] The upper ends of the first ceiling surface 30 and the second ceiling surface 31 are connected to each other. A boundary line 32 between the first ceiling surface 30 and the second ceiling surface 31 extends in the X direction. The boundary line 32 is parallel to a boundary line 24 between the first inclined portion 22 and the second inclined portion 23. The height position of the boundary line 32 is located between the boundary line 24 and the lower end of the first inclined portion 22.

[0033] Boundary line 24 is located closer to second outer wall 19 in the Y direction than boundary line 32. That is, boundary line 24 and boundary line 32 are located at different positions in the Y direction so that they do not overlap each other in the vertical direction. Second chamber 29 has a low ceiling surface 33 that is lower than first ceiling surface 30 and second ceiling surface 31. Low ceiling surface 33 is configured to be horizontal and flat.

[0034] As shown in Figures 4 and 5, the second outer wall 19 has a third outer wall 34 and a fourth outer wall 35 that is located closer to the first outer wall 18 in the Y direction than the third outer wall 34. The third outer wall 34 and the fourth outer wall 35 are connected by a connecting wall 36 that extends in the Y direction in a plan view. The length of the fourth outer wall 35 in the X direction is shorter than that of the third outer wall 34. The length of the fourth outer wall 35 in the X direction is set to, for example, about one-third of that of the third outer wall 34. The second chamber 29 is located between the first outer wall 18 and the fourth outer wall 35.

[0035] The first outer wall 18 has a first window portion 37 provided in the first chamber 28 and a second window portion 38 provided in the second chamber 29. The second window portion 38 is arranged at the innermost position of the second chamber 29 in the first outer wall 18. A shielding portion 39 protruding from the inner surface of the first outer wall 18 is provided near the boundary between the first chamber 28 and the second chamber 29 on the inner surface of the first outer wall 18. The shielding portion 39 in this embodiment is arranged so as to be adjacent to the second window portion 38 in the second chamber 29, for example.

[0036] That is, the shielding portion 39 is arranged so that the second window portion 38 of the second room 29 cannot be seen from the first room 28 in the X direction. The shielding portion 39 is formed, for example, by a fireplace, a bookshelf, a chest of drawers, a thin wall, a thick wall, or the like. A recess 40 is provided in the first outer wall 18 at a position between the first window portion 37 and the shielding portion 39, so as to be recessed outward in the Y direction. That is, the recess 40 is arranged so as to be adjacent to both the first window portion 37 and the shielding portion 39 in the first room 28. The recess 40 accommodates, for example, a bookshelf 41.

[0037] <Structure of the 11 buildings> 5 and 6, the first roof 13 has a first truss 42 provided above the second room 29 and a sloped structural section 43 provided above the first room 28. The second roof 14 has a second truss 44. The first truss 42 has a plurality of beams 45 extending vertically and spaced apart in the Y direction, and a plurality of horizontal members 46 connected to each of the beams 45, extending in the X direction, and spaced apart in the Y direction.

[0038] The second truss member 44 has a plurality of beams 47 extending vertically and a plurality of horizontal connecting members 48 extending horizontally to connect the plurality of beams 47. The plurality of horizontal connecting members 48 are arranged at intervals in the inclination direction of the third inclined section 25. The inclined structural section 43 is arranged between the first truss member 42 and the second truss member 44, and is connected to both the first truss member 42 and the second truss member 44.

[0039] The inclined structural portion 43 has a plurality of cross members 49 extending horizontally in the X direction, which is a direction perpendicular to (intersecting with) the inclination direction of the first inclined portion 22. The plurality of cross members 49 are arranged at intervals in the inclination direction of the first inclined portion 22. The plurality of cross members 49 are connected to one another by a plurality of gradient connecting members 50 extending in the inclination direction of the first inclined portion 22, and are supported at only both ends by columns 51 extending in the vertical direction.

[0040] The number of cross members 49 per unit length in the inclination direction of the first inclined portion 22 of the first roof 13 is greater than the number of horizontal connecting members 48 per unit length in the inclination direction of the third inclined portion 25 of the second roof 14.

[0041] <Operation of the embodiment> Room 27 in building 11 has a structure in which a first room 28 with a sloped ceiling and an open-ceiling structure that reaches up to first roof 13 and a second room 29 with a flat ceiling that is smaller and lower than first room 28 are connected adjacently in the X direction. In other words, room 27 has a structure in which first room 28, which has a relatively large space and an open feeling, and second room 29, which has a relatively small space and an enclosed feeling, are connected.

[0042] This creates a space that gives both a sense of openness and a sense of seclusion in room 27. Therefore, while first room 28 gives the feeling of a large, spacious open space, second room 29 gives the feeling of being enclosed by walls, making life richer.

[0043] 4 and 5, when the second room 29 is viewed in the X direction from the first room 28 in the room 27, the second window 38 of the second room 29 is hidden by the shielding portion 39 and cannot be seen, but the light H that shines into the second room 29 from the second window 38 can be seen. For this reason, the light H creates a light pool in the second room 29. Therefore, the light H that shines into the second room 29 from the second window 38 can be made to look more symbolic. Examples of light H include sunlight, moonlight, and light from an outdoor lamp.

[0044] Furthermore, a recess 40 is formed in the first outer wall 18 so as to be adjacent to the shielding portion 39 in the first room 28, and a bookshelf 41 is housed in the recess 40. The recess 40 housing the bookshelf 41 functions as a light-blocking wall, so the area adjacent to the shielding portion 39 in the first room 28 is darkened. Therefore, in the first room 28, the darkened area adjacent to the shielding portion 39 and the area that is reached by the light H that enters through the first window portion 37 create a contrast between light and dark, creating an appealing atmosphere.

[0045] <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 22 that slopes downward toward exterior wall 17, and a room 27 provided below first roof 13. Room 27 comprises a first room 28 that has an open-ceiling structure extending up to first roof 13 and has a first ceiling surface 30 that follows first inclined portion 22, and a second room 29 that is connected to first room 28 and has a low ceiling surface 33 that is lower than first ceiling surface 30.

[0046] According to this configuration, room 27 has a structure in which first room 28, which has a relatively large open-ceiling structure and gives an open feeling, is connected to second room 29, which has a relatively small space with a lower ceiling than first room 28 and gives an enclosed feeling. This makes it possible to create a space that gives both an open feeling and an enclosed feeling.

[0047] (2) In the building 11, the low ceiling surface 33 is configured flat. According to this configuration, the second chamber 29 can be made into a space that gives a feeling of closure and relaxation.

[0048] (3) In the building 11, the first roof 13 has a second inclined portion 23 that slopes downward toward the side opposite the first inclined portion 22. The exterior wall 17 has a first exterior wall 18 that intersects with the first inclined portion 22 and a second exterior wall 19 that intersects with the second inclined portion 23 and faces the first exterior wall 18. A room 27 is disposed between the first exterior wall 18 and the second exterior wall 19. The second exterior wall 19 has a third exterior wall 34 and a fourth exterior wall 35 that is disposed closer to the first exterior wall 18 than the third exterior wall 34. The second room 29 is disposed between the first exterior wall 18 and the fourth exterior wall 35.

[0049] According to this configuration, the width of the second chamber 29 in the opposing direction between the first outer wall 18 and the second outer wall 19 is narrower than the width of the first chamber 28 in the opposing direction between the first outer wall 18 and the second outer wall 19, thereby further enhancing the sense of enclosure in the second chamber 29.

[0050] (4) In the building 11, a shielding portion 39 protruding from the inner surface of the first outer wall 18 is provided near the boundary between the first room 28 and the second room 29 on the inner surface of the first outer wall 18. According to this configuration, the shielding portion 39 can hide a part of the second chamber 29.

[0051] (5) In the building 11, the first exterior wall 18 has a first window portion 37 provided in the first room 28 and a second window portion 38 provided in the second room 29. The shielding portion 39 is positioned so that the second window portion 38 of the second room 29 cannot be seen from the first room 28.

[0052] According to this configuration, when the second chamber 29 is viewed from the first chamber 28, the second window portion 38 of the second chamber 29 cannot be seen, but the light H shining into the second chamber 29 from the second window portion 38 can be seen. Therefore, the light H shining into the second chamber 29 from the second window portion 38 can be more symbolically displayed.

[0053] (6) In the building 11, a recess 40 is provided in the first exterior wall 18 so as to be recessed outward. The recess 40 is disposed adjacent to the shielding portion 39 in the first room .

[0054] According to this configuration, recess 40 has a light-blocking property, and therefore can darken the area adjacent to shielding portion 39 in first chamber 28. Therefore, in first chamber 28, a sense of light and darkness can be perceived between the darkened area adjacent to shielding portion 39 and the area that receives light H entering through first window portion 37. Also, a bookshelf 41, for example, can be placed in recess 40.

[0055] (7) The building 11 has a second roof 14 having a third inclined portion 25 inclined along the first inclined portion 22 and a fourth inclined portion 26 inclined along the second inclined portion 23. The second roof 14 is positioned offset from the first roof 13 in a direction along the boundary line 24 between the first inclined portion 22 and the second inclined portion 23. According to this configuration, the first roof 13 and the second roof 14 are aligned in a direction along the ridge of the first roof 13, which contributes to improving the design.

[0056] (8) In the building 11, the first roof 13 has a first truss 42 provided above the second room 29 and a sloped structural section 43 provided above the first room 28. The second roof 14 has a second truss 44. The sloped structural section 43 is disposed between the first truss 42 and the second truss 44 and is connected to the first truss 42 and the second truss 44. According to this configuration, the inclined structural portion 43, which has a relatively low strength, can be reinforced by the first truss 42 and the second truss 44, which have a relatively high strength.

[0057] (9) In the building 11, the inclined structural portion 43 has a plurality of cross members 49 extending horizontally in a direction intersecting the inclination direction of the first inclined portion 22. The plurality of cross members 49 are connected to one another by inclined connecting members 50 extending in the inclination direction of the first inclined portion 22, and are supported by columns 51 at only both ends. The second truss 44 has a plurality of beams 47 extending vertically and horizontal connecting members 48 extending horizontally to connect the plurality of beams 47. The number of cross members 49 per unit length in the inclination direction of the first inclined portion 22 of the first roof 13 is greater than the number of horizontal connecting members 48 per unit length in the inclination direction of the third inclined portion 25 of the second roof 14.

[0058] With this configuration, the density of the cross members 49 is greater than the density of the horizontal connecting members 48, so the strength of the first roof 13, which has lower strength than the second roof 14, can be brought closer to the strength of the second roof 14.

[0059] <Modification> The above-described 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-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] The number of cross members 49 per unit length in the inclination direction of the first inclined portion 22 of the first roof 13 does not necessarily have to be greater than the number of horizontal connecting members 48 per unit length in the inclination direction of the third inclined portion 25 of the second roof 14.

[0061] The inclined structural portion 43 does not necessarily have to be disposed between the first truss 42 and the second truss 44 and connected to the first truss 42 and the second truss 44 . 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 boundary line 24 between the first inclined portion 22 and the second inclined portion 23 .

[0062] The recess 40 does not necessarily have to be recessed outward in the first outer wall 18. In other words, the recess 40 may be omitted. The recess 40 does not necessarily have to be disposed adjacent to the shielding portion 39 in the first chamber 28 .

[0063] The shielding portion 39 does not necessarily have to be positioned so that the second window portion 38 of the second chamber 29 cannot be seen from the first chamber 28. The shielding portion 39 may be omitted.

[0064] The second outer wall 19 does not necessarily have to have the third outer wall 34 and the fourth outer wall 35 disposed closer to the first outer wall 18 than the third outer wall 34 . The low ceiling surface 33 does not necessarily have to be flat. That is, the low ceiling surface 33 may be inclined with respect to the horizontal plane. That is, the second room 29 may have a sloped ceiling.

[0065] The first roof 13 may be configured as, for example, a shed roof. In this case, either the first inclined portion 22 or the second inclined portion 23 of the first roof 13 is omitted. The second roof 14 and the second main body portion 16 may be omitted.
