Description

building

[0001] The present disclosure relates to buildings.

[0002] Patent Document 1 discloses a building structure that creates a connection between an indoor space and an outdoor space at the lower end of a sloped ceiling.

[0003] Japanese Patent Application Laid-Open No. 2022-026421

[0004] There is a need to create a connection between the indoor and outdoor spaces at the top of the sloped ceiling.

[0005] (1) A building that is one aspect of the present disclosure is a building that includes a sloped ceiling, a wall that is located at the upper end of the sloped ceiling in a plan view and has an opening into which a window member is fitted, and a sloped protrusion that is located on the upper end side of the sloped ceiling closer to the outdoors than the wall and extends parallel to the sloped ceiling, and the upper end of the sloped ceiling is located below the upper partition screen that is located at the top of the partition screen that defines the opening.

[0006] The ceiling is then fitted with a cover member that covers the upper end of the sloped ceiling from below, and the cover member has a first panel that extends downward from the upper section screen and a second panel that extends from the first panel toward the cover member, and the cover member is fitted with a cover member that extends from the opening to the part of the wall where the opening is not provided.

[0007] A possible configuration for the border structure between the upper end of a sloped ceiling and a wall is to separately place decorative elements on the opening and the non-opening portion of the wall (hereinafter referred to as the "non-opening portion of the wall"). The decorative elements placed on the opening and the non-opening portion of the wall can be configured as follows, for example: The decorative element placed on the opening has a fascia portion extending downward from the upper section and a border portion covering the upper end of the sloped ceiling from below. The decorative element placed on the non-opening portion of the wall also covers the upper end of the sloped ceiling from below. However, with this configuration, the decorative element is separated at the boundary between the opening and the non-opening portion of the wall, so the butt portion between the decorative element placed on the opening and the non-opening portion of the wall is exposed indoors. This detracts from the design of the border structure. This is particularly true when a difference in level occurs between the decorative element placed on the opening and the non-opening portion of the wall due to construction errors or other factors.

[0008] In contrast, with the above-mentioned configuration, a cover member is provided at the opening, and a trim material is provided from the opening to the non-opening portion of the wall. In this case, there is no abutment of the decorative material at the boundary between the opening and the non-opening portion of the wall. Therefore, the design of the trim structure between the sloped ceiling and the wall at the upper end of the sloped ceiling can be improved.

[0009] (3) In the building of (2) above, when the wall is the first wall, it is provided with a second wall and a third wall that are connected by the first wall and face each other, and the trim extends from the second wall to the third wall.

[0010] With this configuration, the trim material is connected without being divided from the second wall to the third wall, so there is no abutment of the decorative material between the second wall and the third wall. Therefore, the design of the trim structure between the sloped ceiling and the wall at the upper end of the sloped ceiling can be further improved.

[0011] (4) In the building of (2) or (3) above, a frame is provided to be fitted into the opening, the frame including a vertical frame extending in the vertical direction, a portion of the vertical frame being located on the indoor side of the inner surface of the wall, the trim material being positioned in contact with the indoor side surface of the vertical frame, and a spacer being provided between the inner surface of the wall and the trim material.

[0012] When a portion of the vertical frame is located inside the wall and the trim is positioned so that it contacts the indoor surface of the vertical frame, a gap occurs between the wall's inner surface and the trim, which impairs the design. With the above configuration, the spacer can fill the gap between the wall's inner surface and the trim. This improves the design of the trim structure between the sloped ceiling and the wall at the top of the sloped ceiling.

[0013] Furthermore, if the portion of the vertical frame located closer to the interior than the inner wall surface is cut out and a trim is placed in the cutout, no gap will be created between the inner wall surface and the trim, but in this case, the vertical frame will still need to be cut out. Because the frame is located at the top of the sloped ceiling, cutting out the vertical frame requires high-altitude work. When working at high altitudes using scaffolding, workers' feet are more likely to be unstable than when working on the ground. Furthermore, because the sloped ceiling requires cutting out the vertical frame, the work is performed above the worker's head, which makes it difficult for the worker's helmet to interfere with the sloped ceiling, making the work more difficult. Therefore, by providing a spacer between the wall and the trim as in the above configuration, the work of cutting out the frame is unnecessary, improving workability.

[0014] (5) In the building described in (4) above, the frame further includes an upper frame arranged along the upper compartment surface, and the upper end of the sloped ceiling is located below the lower surface of the upper frame.

[0015] The ceiling is formed of a material that is oriented in a vertical direction, and the upper surface of the window panel is inclined to extend parallel to the slope of the ceiling, and the lower ...

[0016] With this configuration, when a person inside the room looks up at the window, part of the underside of the second panel is shaded by the trim, reducing the visible area that is visible to the person inside the room. The trim also hides the abutment between the trim and the second panel, improving the design of the opening.

[0017] (7) In the building of any one of (2) to (6) above, the second curtain board is separate from the first curtain board. With this configuration, the vertical dimension of the first curtain board is set according to the vertical dimension of the upper frame of the window member, making it possible to accommodate multiple types of window members with different vertical dimensions of the upper frame. Therefore, the second curtain board can be standardized regardless of the type of window member.

[0018] The building disclosed herein makes it easier for people inside to feel a connection between the indoors and outdoors.

[0020] A building 10 according to this embodiment will be described with reference to FIGS. 1 to 7. As shown in FIGS. 1 and 2, the building 10 includes a sloped ceiling 11 and a first wall 12. The sloped ceiling 11 constitutes an indoor ceiling. The sloped ceiling 11 includes a rafter 21, a ceiling material 22 fixed to the rafter 21, and a rafter 23 fixed to the ceiling material 22. The ceiling material 22 is made of gypsum board. The rafter 21, the ceiling material 22, and the rafter 23 constitute a ceiling base material. The sloped ceiling 11 also includes a ceiling decorative material 24 fixed to the ceiling base material and a mounting member 25 for attaching the sloped ceiling 11 to the first wall 12. In the following description, if the slope of the sloped ceiling 11 is broken down into a vertical component and a horizontal component, the direction along the horizontal component is referred to as the first direction X. The direction perpendicular to the first direction X and the vertical direction Z is referred to as the second direction Y. The first wall 12 constitutes an exterior wall and is located on the upper end side of the sloped ceiling 11 in a plan view.

[0021] As shown in Fig. 3, the building 10 includes a second wall 13 and a third wall 14. The second wall 13 and the third wall 14 are connected in the second direction Y by the first wall 12. The second wall 13 and the third wall 14 face each other in the second direction Y. Note that the sloped ceiling 11 is not shown in Fig. 3.

[0022] As shown in Figures 1 and 2, the building 10 has a sloped roof 15. The sloped roof 15 in this embodiment is a single-shed roof. The sloped roof 15 extends parallel to the sloped ceiling 11. The sloped roof 15 has eaves 15a as sloped protrusions. The eaves 15a are located on the upper end side of the sloped ceiling 11, closer to the exterior than the first wall 12. The eaves 15a are inclined so that they are positioned higher the further they are from the first wall 12. The eaves 15a extend parallel to the sloped ceiling 11.

[0023] As shown in Figure 4, the first wall 12 has an eaves beam 31 and an opening frame 32. The eaves beam 31 extends in the second direction Y. The opening frame 32 is provided below the eaves beam 31. The opening frame 32 has two vertical shafts 33 extending in the up-down direction Z and two horizontal shafts 34 extending in the second direction Y. Note that Figure 4 shows only the upper horizontal shaft 34 of the two horizontal shafts 34. The upper ends of the two vertical shafts 33 are each connected to the eaves beam 31. The two horizontal shafts 34 each connect two vertical shafts 33.

[0024] The opening 120 is defined by two vertical axes 33 and two horizontal axes 34. Thus, the opening 120 is provided in the first wall 12. Of the partition surfaces defining the opening 120, an upper partition surface 121 located at the top is formed by the lower surface of the upper horizontal axis 34 of the two horizontal axes 34. Of the partition surfaces defining the opening 120, two vertical partition surfaces 122 extending in the up-down direction Z are formed by the opposing surfaces of the two vertical axes 33. Although not shown, of the partition surfaces defining the opening 120, a lower partition surface located at the bottom is formed by the upper surface of the lower horizontal axis 34 of the two horizontal axes 34.

[0025] The first wall 12 includes an upper interior wall material 41, a first lower interior wall material 42, and a second lower interior wall material 43. The upper interior wall material 41, the first lower interior wall material 42, and the second lower interior wall material 43 are each made of gypsum board. The upper interior wall material 41, the first lower interior wall material 42, and the second lower interior wall material 43 are located indoors relative to the eaves beam 31 and the opening frame 32. The indoor surfaces of the upper interior wall material 41, the first lower interior wall material 42, and the second lower interior wall material 43 form the inner surface 12a of the first wall 12. The upper interior wall material 41 extends from the second wall 13 to the third wall 14 in the second direction Y. The upper interior wall material 41 includes a portion located below the upper partition surface 121. The upper inner wall material 41 is fixed to the upper horizontal shaft 34 of the two vertical shafts 33 and two horizontal shafts 34. The first lower inner wall material 42 and the second lower inner wall material 43 are located below the upper inner wall material 41. The first lower inner wall material 42 is located closer to the second wall 13 than the opening 120 in the second direction Y. The second lower inner wall material 43 is located closer to the third wall 14 than the opening 120 in the second direction Y.

[0026] As shown in FIG. 1 , the first wall 12 has a mounting base material 44. The mounting base material 44 is provided to mount several joists 21 of the sloped ceiling 11 to the first wall 12. The mounting base material 44 is positioned in a position corresponding to the opening 120 in the second direction Y. The mounting base material 44 is positioned in the second direction Y between two vertical frames 72 of the frame 17 (described later). The mounting base material 44 includes a portion located below the upper partition surface 121. The mounting member 25 of the sloped ceiling 11 is fixed to a portion of the mounting base material 44 located below the upper partition surface 121. The mounting base material 44 is fixed to the upper interior wall material 41. As described above, the upper interior wall material 41 is fixed to the horizontal shaft 34. Therefore, the sloped ceiling 11 is indirectly fixed to the horizontal shaft 34.

[0027] <Window Member, Frame> The building 10 includes a window member 16 and a rectangular frame 17. The window member 16 and the frame 17 are fitted into the opening 120.

[0028] The window member 16 has a rectangular window frame 61 and a shoji screen 62 fitted into the window frame 61. The shoji screen 62 has a rectangular frame-shaped stile 63 and window glass 64 fitted into the stile 63. The stile 63 includes an upper frame 63a. The upper frame 63a extends in the second direction Y. The upper frame 63a is arranged to fit along the upper section screen 121.

[0029] As shown in Figure 4, the frame 17 has an upper frame 71, a lower frame (not shown), and two vertical frames 72. The upper frame 71 and the lower frame extend in the second direction Y. The upper frame 71 is disposed along the upper partition surface 121. The lower frame is disposed along the lower partition surface.

[0030] 5, the upper frame 71 has a frame body 711 and a window decorative material 712 that covers the frame body 711 from below. The lower surface of the window decorative material 712 forms the lower surface 71a of the upper frame 71. The window decorative material 712 in this embodiment is the same color and made of the same material as the ceiling decorative material 24.

[0031] As shown in Figure 4, the vertical frame 72 extends in the up-down direction Z. The vertical frame 72 is arranged along the vertical partition surface 122. A portion of the vertical frame 72 is located indoors relative to the inner surface 12a of the first wall 12 (see Figure 1). In this embodiment, a notch 41a is provided in the lower surface of the upper inner wall material 41. The vertical frame 72 is arranged within the notch 41a.

[0032] 5, the upper end 11a of the sloped ceiling 11 is located below the upper partition surface 121. In this embodiment, the upper end 11a of the sloped ceiling 11 is located below the lower surface 71a of the upper frame 71 of the frame 17.

[0033] <Edge Structure> The edge structure between the sloped ceiling 11 and the first wall 12 at the upper end side of the sloped ceiling 11 will be described.

[0034] As shown in Figures 3 and 5, the building 10 includes a cover member 18. The cover member 18 is provided in the opening 120. The cover member 18 has a first curtain board portion 81 and a second curtain board portion 82. In this embodiment, the first curtain board portion 81 and the second curtain board portion 82 are separate bodies. In this embodiment, the first curtain board portion 81 is flat. The first curtain board portion 81 extends downward from the upper partition surface 121. In this embodiment, the first curtain board portion 81 extends downward from the lower surface 71a of the upper frame 71 of the frame 17. The first curtain board portion 81 is fixed to a portion of the outdoor surface of the upper interior wall material 41 that is located below the lower surface 71a of the upper frame 71. The second curtain board portion 82 extends from the lower end of the first curtain board portion 81 toward the indoor side. The lower end of the first curtain board 81 is positioned in a notch provided above the outdoor end of the second curtain board 82. The second curtain board 82 is fixed to the lower end of the first curtain board 81 and the underside of the ceiling material 22. The underside 82a of the second curtain board 82 is inclined so that it is positioned lower as it moves from the outdoor side to the indoor side. The underside 82a of the second curtain board 82 extends parallel to the sloped ceiling 11. The underside 82a of the second curtain board 82 is provided on the same plane as the underside 11b of the sloped ceiling 11.

[0035] As shown in Figures 5 and 6, the building 10 is equipped with a trim 19. The trim 19 covers the upper end 11a of the sloped ceiling 11 from below. The trim 19 in this embodiment is the same color and material as the ceiling decorative material 24. The trim 19 is fixed to the underside of the ceiling material 22. The trim 19 in this embodiment is positioned so as to contact the indoor surface of the vertical frame 72 of the frame 17. In the opening 120, the second header panel 82 of the cover member 18 extends from the first header panel 81 toward the trim 19. The tip surface of the second header panel 82 abuts against the outdoor surface of the trim 19. The trim 19 is located between the ceiling decorative material 24 and the second header panel 82.

[0036] The underside 19a of the trim 19 is inclined downward from the outdoor side toward the indoor side. The underside 19a of the trim 19 extends parallel to the sloped ceiling 11. The underside 19a of the trim 19 protrudes downward relative to the underside 11b of the sloped ceiling 11 and the underside 82a of the second fascia panel portion 82.

[0037] 3 and 7 , the trim 19 extends in the second direction Y. The trim 19 is provided in the second direction Y from the opening 120 to a portion of the first wall 12 where the opening 120 is not provided, i.e., the non-opening portion of the first wall 12. The trim 19 of this embodiment extends in the second direction Y from the second wall 13 to the third wall 14.

[0038] As shown in Figures 6 and 7, in the portion where no opening 120 is provided in the second direction Y, a spacer 20 is provided between the inner surface 12a of the first wall 12 and the trim 19. The spacer 20 in this embodiment is the same color and material as the ceiling decorative material 24. The spacer 20 extends in the second direction Y. The lower surface 20a of the spacer 20 is inclined so that it is positioned lower as it moves from the outdoor side to the indoor side. The lower surface 20a of the spacer 20 extends parallel to the sloped ceiling 11. The lower surface 20a of the spacer 20 is provided on the same plane as the lower surface 11b of the sloped ceiling 11. The lower surface 19a of the trim 19 protrudes downward relative to the lower surface 20a of the spacer 20.

[0039] [Operation of this embodiment] The operation of this embodiment will be described. The building 10 includes a sloped ceiling 11, a first wall 12, and a sloped roof 15. The first wall 12 is located at the upper end of the sloped ceiling 11 in a plan view. The first wall 12 has an opening 120 into which a window member 16 is fitted. The sloped roof 15 has eaves 15a located at the upper end of the sloped ceiling 11 and closer to the exterior than the first wall 12. The eaves 15a extend parallel to the sloped ceiling 11. The upper end 11a of the sloped ceiling 11 is located below an upper partition surface 121, which is located at the top of the partition surface that defines the opening 120. This makes it difficult for people indoors to see the upper frame 63a of the window member 16 when looking up at the window, thereby making it easier to feel a connection between the indoors and outdoors. When people indoors look up at the window and can see the eaves 15a, the sloped ceiling 11 and the eaves 15a appear to be continuous.

[0040] [Advantages of this embodiment] The advantages of this embodiment are as follows: (1) The upper end 11a of the sloped ceiling 11 is located below the upper partition wall 121 that defines the opening 120. With this configuration, people inside the building will find it difficult to see the upper frame 63a of the window member 16 when looking up at the window, which makes it easier for them to feel a connection between the indoors and outdoors.

[0041] (2) As a trim structure between the sloped ceiling 11 and the first wall 12 at the upper end side of the sloped ceiling 11, a configuration in which decorative members are individually placed for the opening 120 and the non-opening portion of the first wall 12 is conceivable. The following configurations are conceivable as examples of the configuration of the decorative member placed in the opening 120 and the non-opening portion of the first wall 12. The decorative member placed in the opening 120 has a fascia panel portion extending downward from the upper partition surface 121, like the cover member 18 of this embodiment, and a trim portion covering the upper end portion 11a of the sloped ceiling 11 from below, like the trim member 19 of this embodiment. The decorative member placed in the non-opening portion of the first wall 12 covers the upper end portion 11a of the sloped ceiling 11 from below, like the trim member 19 of this embodiment.

[0042] However, in this configuration, the decorative member is separated at the boundary between the opening 120 and the non-opening portion of the first wall 12, so the abutting portion between the decorative member placed at the opening 120 and the decorative member placed at the non-opening portion of the first wall 12 is exposed indoors. This impairs the design of the trim structure. In particular, if a difference in level occurs between the decorative member placed at the opening 120 and the decorative member placed at the non-opening portion of the first wall 12 due to construction errors or the like, the design of the trim structure is further impaired.

[0043] The building 10 of this embodiment includes a trim 19 that covers the upper end 11a of the sloped ceiling 11 from below, and a cover member 18 provided at the opening 120. The cover member 18 has a first fascia portion 81 that extends downward from an upper partition surface 121, and a second fascia portion 82 that extends from the first fascia portion 81 toward the trim 19. The trim 19 is provided from the opening 120 to the non-opening portion of the first wall 12. In this case, there is no abutment of the decorative members at the boundary between the opening 120 and the non-opening portion of the first wall 12. This improves the design of the trim structure between the sloped ceiling 11 and the first wall 12 at the upper end of the sloped ceiling 11.

[0044] (3) The building 10 includes a second wall 13 and a third wall 14. The second wall 13 and the third wall 14 are connected by the first wall 12 and face each other. The trim 19 extends from the second wall 13 to the third wall 14. With this configuration, the trim 19 is connected without being separated from the second wall 13 to the third wall 14, so there is no abutment of the decorative members between the second wall 13 and the third wall 14. Therefore, the design of the trim structure between the sloped ceiling 11 and the first wall 12 at the upper end side of the sloped ceiling 11 can be further improved.

[0045] (4) The building 10 is provided with a frame 17 that fits into the opening 120. The frame 17 includes a vertical frame 72 that extends in the up-down direction Z. A portion of the vertical frame 72 is located on the indoor side of the inner surface 12a of the first wall 12. The trim 19 is disposed in a position that contacts the indoor side surface of the vertical frame 72. A spacer 20 is provided between the inner surface 12a of the first wall 12 and the trim 19.

[0046] If a portion of the vertical frame 72 protrudes indoors beyond the inner surface 12a of the first wall 12 and the trim 19 is positioned to contact the indoor surface of the vertical frame 72, a gap will form between the inner surface 12a of the first wall 12 and the trim 19. If a gap forms between the inner surface 12a of the first wall 12 and the trim 19, a depression will form between the inner surface 12a of the first wall 12 and the trim 19, or the ceiling material 22 will be exposed indoors through the gap, thereby compromising the design. In contrast, in this embodiment, the spacer 20 can fill the gap that forms between the inner surface 12a of the first wall 12 and the trim 19. Therefore, the design of the trim structure between the sloped ceiling 11 and the first wall 12 at the upper end of the sloped ceiling 11 can be improved.

[0047] If the vertical frame 72 is cut out from the inner surface 12a of the first wall 12 toward the interior side and a trim 19 is placed in the cutout, no gap will be created between the inner surface 12a of the first wall 12 and the trim 19. However, in this case, the work of cutting out the vertical frame 72 is required. Because the frame 17 is located at the upper end of the sloped ceiling 11, cutting out the vertical frame 72 requires high-altitude work. When working at high altitudes using scaffolding, workers' feet are more likely to be unstable than when working on the ground. Furthermore, because of the sloped ceiling 11, cutting out the vertical frame 72 requires the work to be done above the worker's head, which makes it easier for the worker's helmet to interfere with the sloped ceiling 11, resulting in poor workability. Therefore, by providing a spacer 20 between the first wall 12 and the trim 19 as in this embodiment, the work of cutting out the frame 17 is unnecessary, improving workability.

[0048] (5) The frame 17 further includes an upper frame 71 that is arranged along the upper section surface 121. The upper end 11a of the sloped ceiling 11 is located below the lower surface 71a of the upper frame 71. This configuration makes it more difficult for people inside the building to see the upper frame 63a of the window member 16 when they look up at the window, making it easier for them to feel a connection between the indoors and outdoors.

[0049] (6) The underside 19a of the trim 19 and the underside 82a of the second curtain panel 82 each extend parallel to the sloped ceiling 11. The underside 19a of the trim 19 protrudes downward relative to the underside 82a of the second curtain panel 82. With this configuration, when a person inside the room looks up at the window, part of the underside 82a of the second curtain panel 82 is shaded by the trim 19, thereby reducing the visible surface area that is visible to the person inside the room. In addition, the trim 19 hides the abutment portion between the trim 19 and the second curtain panel 82. This improves the design of the opening 120.

[0050] (7) The second curtain panel 82 is separate from the first curtain panel 81. With this configuration, the dimension of the first curtain panel 81 in the up-down direction Z can be set according to the dimension of the upper frame 63a of the window member 16 in the up-down direction Z, thereby making it possible to accommodate multiple types of window members 16 having different dimensions of the upper frame 63a in the up-down direction Z. Therefore, the second curtain panel 82 can be made common regardless of the type of window member 16. Note that in this embodiment, the first curtain panel 81 is a flat panel that is easy to produce, and therefore the first curtain panel 81 can be easily produced even if the dimension of the first curtain panel 81 in the up-down direction Z varies depending on the type of window member 16.

[0051] (8) The upper inner wall material 41 has a notch 41a. The vertical frame 72 of the frame 17 is placed in the notch 41a. In this case, construction is easier than when the vertical frame 72 of the frame 17 is notched and the upper inner wall material 41 is placed in the notch.

[0052] (9) The ceiling decorative material 24, the trim material 19, and the spacer 20 of the sloped ceiling 11 are the same color and material. This improves the sense of unity between the ceiling decorative material 24, the trim material 19, and the spacer 20, thereby improving the design of the trim structure between the sloped ceiling 11 and the first wall 12 at the upper end of the sloped ceiling 11.

[0053] <Modifications> The above-described embodiments are examples of possible forms of the building 10 and are not intended to limit the form. The building 10 may take forms different from those illustrated in the above-described embodiments. Examples include forms in which part of the configuration of the embodiment is replaced, modified, or omitted, or forms in which a new configuration is added to the embodiment. Modifications of the embodiments are shown below.

[0054] In the above embodiment, the sloped protrusion is formed by the eaves 15a of the sloped roof 15, but this is not limited to this. The sloped protrusion may be formed by eaves extending from the first wall 12 to the exterior. The eaves that form the sloped protrusion are inclined so that they are positioned higher the further they are from the first wall 12. The eaves that form the sloped protrusion extend parallel to the sloped ceiling 11.

[0055] As a partition structure between the sloped ceiling 11 and the first wall 12 at the upper end of the sloped ceiling 11, for example, decorative members may be separately placed at the opening 120 and the non-opening portion of the first wall 12. The decorative member placed at the opening 120 has a fascia panel portion extending downward from the upper partition surface 121 and a partition portion covering the upper end 11a of the sloped ceiling 11 from below. The decorative member placed in the non-opening portion of the first wall 12 covers the upper end 11a of the sloped ceiling 11 from below.
