Description

[Technical Field]

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

[0002] Patent Document 1 discloses a house having an upper floor and a lower floor, with an intermediate floor (skip floor) on the upper floor. In the house of Patent Document 1, an upper floor living space such as a bedroom is formed above the intermediate floor, and a storage space is formed below the intermediate floor. In this case, both the upper floor living space and the storage space are low-ceilinged spaces. In addition, windows are provided on the exterior walls of the upper floor living space and the storage space. This makes it possible to introduce outside light into the upper floor living space and storage space through each window. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-144391 Summary of the Invention [Problem to be solved by the invention]

[0004] In the house of Patent Document 1, the windows in the upper floor living space and the storage space are both formed to fit the ceiling height of these low-ceilinged spaces. As a result, the vertical dimensions of these windows are significantly smaller than the other windows on the upper floors. In this case, when the house is viewed from the outside, these windows appear out of balance with the other windows, which could mar the appearance of the house.

[0005] It is also possible to avoid damaging the appearance of the house by not installing windows in the living spaces and storage spaces on the upper floors, but this is undesirable because it would prevent outside light from entering these spaces.

[0006] The present invention was made in consideration of the above circumstances, and its main purpose is to enable light to enter both the lower space and the upper space separated by the skip floor section in a house equipped with a skip floor section, while minimizing damage to the appearance. [Means for solving the problem]

[0007] In order to solve the above problem, the house of the first invention is a house comprising a skip floor section set at a height different from the normal floor height, and a lower space section and an upper space section separated vertically by the skip floor section, wherein the lower space section and the upper space section are adjacent to the outdoors separated by an exterior wall section, and the exterior wall section is provided with a light-transmitting window section that extends vertically across the skip floor section and allows light to enter each of the lower space section and the upper space section.

[0008] According to the first aspect of the present invention, the daylight window extends across the skip floor section from top to bottom, so the size of the daylight window is not limited by the skip floor section. This ensures a balance between the daylight window section and other windows. Furthermore, because the daylight window extends across the skip floor section from top to bottom, it is possible to admit light to both the lower space section and the upper space section. This makes it possible for a house equipped with a skip floor section to admit outside light to both the lower space section and the upper space section while minimizing damage to the exterior appearance.

[0009] The second invention is a house according to the first invention, characterized in that the skip floor section is composed of a ceiling surface material that forms the ceiling surface of the lower space section and a floor surface material that forms the floor surface of the upper space section, and is provided with a cover member that is provided between the light-transmitting window section and the skip floor section and that covers the space between the floor surface material and the ceiling surface material from the light-transmitting window section side.

[0010] In the first aspect of the present invention, in which the skylight section is installed across the skip floor section from above and below, it is possible that the skip floor section may be visible through the skylight section from the outside. Because the skip floor section is composed of a ceiling surface material in the lower space and a floor surface material in the upper space, there is a risk that components such as base materials arranged between the floor surface material and the ceiling surface material may also be visible from the outside. This could significantly impair the appearance of the house by exposing these normally invisible components.

[0011] In view of this, in the second invention, a cover member is provided between the light-receiving window and the skip floor, and this cover member conceals the gap between the floor surface material and the ceiling surface material in the skip floor from the light-receiving window side. This makes it possible to prevent the gap between the floor surface material and the ceiling surface material from being seen from the outside through the light-receiving window, thereby avoiding significant impairment of the appearance of the house.

[0012] The third invention is a house according to the second invention, characterized in that the exterior wall has a window opening in which the light-transmitting window is provided, and the light-transmitting window is positioned closer to the outdoors in the window opening, so that the light-transmitting window and the skip floor are spaced apart, and the cover member has a covering portion that conceals the space between the ceiling surface material and the floor surface material, and an extension portion that extends from the covering portion toward the light-transmitting window.

[0013] Typically, the light-receiving window is positioned closer to the exterior of the window opening. Therefore, in a configuration in which the light-receiving window spans the skip floor vertically, the light-receiving window and the skip floor are spaced apart. This raises the concern that objects in the upper space may fall into the lower space through the gap between the light-receiving window and the skip floor. Therefore, according to the third aspect of the invention, the cover member has a covering portion that conceals the gap between the ceiling surface material and the floor surface material, and an extension portion that extends from the covering portion toward the light-receiving window. In this case, the extension portion covers the gap between the light-receiving window and the skip floor. This prevents objects in the upper space from falling into the lower space.

[0014] A fourth aspect of the present invention is the house of the third aspect, characterized in that the extension portion extends from an upper end of the cover portion.

[0015] In the configuration of the third invention, in which an extension is provided between the light-receiving window and the skip floor, there is a concern that the extension blocks the external light that enters through the light-receiving window, limiting the light that enters the lower space below the extension. In this regard, according to the fourth invention, the extension extends from the upper end of the cover. This prevents the extension from limiting the light that enters the lower space. Therefore, light can be more effectively introduced into the lower space.

[0016] The fifth invention is a house according to the fourth invention, characterized in that the floor material has a floor finishing surface material that forms the floor surface of the upper space portion, and a portion of the floor finishing surface material is placed on the upper surface side of the extension portion, or another floor material adjacent to the floor finishing surface material is placed on the upper surface side of the extension portion.

[0017] According to the fifth invention, the extension portion is covered from above by a part of the floor finishing surface material (or another adjacent floor finishing surface material), thereby preventing the extension portion from spoiling the appearance of the upper space.

[0018] The sixth invention is a house according to the fifth invention, characterized in that the cover member has a rising portion that rises from the end of the extension portion on the light-transmitting window portion side, and the rising portion covers and conceals a part of the floor finishing surface material or another floor finishing surface material placed on the upper surface side of the extension portion from the light-transmitting window portion side.

[0019] According to the sixth aspect of the present invention, even if a floor finishing surface material is placed on the upper surface of the extension portion, the rising portion can obscure the floor finishing surface material from the lighting window side. This makes it possible to prevent the floor finishing surface material from being seen through the lighting window from the outside, more reliably avoiding damage to the appearance of the house.

[0020] The seventh invention is a house according to any one of the second to sixth inventions, characterized in that the exterior wall has a window opening in which the light-transmitting window is provided, a window frame is arranged along the periphery of the window opening, and the light-transmitting window is arranged on the outdoor side of the window frame, and the cover member has a covering portion that is arranged in the middle of the window opening in the indoor / outdoor direction and conceals the space between the ceiling surface material and the floor surface material, and a fixing portion that extends from the side end of the covering portion to the opposite side of the light-transmitting window and is fixed to the window frame.

[0021] According to the seventh aspect of the present invention, the fixing portion extends from the side edge of the cover portion to the side opposite the light-receiving window portion. This makes it possible to make the fixing portion invisible from the outside through the light-receiving window portion, thereby more reliably preventing damage to the appearance of the house.

[0022] The eighth invention of the house is characterized in that, in any of the second to seventh inventions, the floor surface material has a subfloor surface material and a floor finishing surface material that is layered on top of the subfloor surface material to form the floor surface of the upper space, and the cover member has a mounting portion placed on the upper surface of the subfloor surface material, and the mounting portion is arranged in a sandwiched state between the subfloor surface material and the floor finishing surface material.

[0023] According to the eighth aspect of the present invention, the cover member has a mounting portion. The mounting portion is placed on the upper surface of the subfloor surface material. In this case, the height position of the cover member is determined by the mounting portion. This makes it possible to easily align the cover member when fixing it to the skip floor portion. Furthermore, the mounting portion is arranged sandwiched between the subfloor surface material and the floor finishing surface material. As a result, the mounting portion is covered from above by the floor finishing surface material, which prevents the mounting portion from spoiling the appearance of the upper space portion.

[0024] A ninth aspect of the present invention is a house according to any one of the second to eighth aspects of the present invention, characterized in that the surface of the cover member facing the light-receiving window portion is colored a dark color.

[0025] If a cover member is provided between the skylight window and the skip floor, there is a concern that the cover member may be visible through the skylight window from the outside. According to the ninth invention, the surface of the cover member facing the skylight window is colored a dark color. This prevents the cover member from being noticeable through the skylight window, more reliably preventing the appearance of the house from being marred. [Brief explanation of the drawings]

[0027] An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a house is embodied as a two-story modular house. The modular house is constructed by combining a plurality of building units. Figure 1 is a cross-sectional view showing a part of the house.

[0028] As shown in Figure 1, the house 10 has a first floor portion 11, a second floor portion 12, and a roof portion 13 provided above the second floor portion 12. A first floor space 15 is provided in the first floor portion 11, and a second floor space 16 is provided in the second floor portion 12. The first floor space 15 is, for example, a hallway, and the second floor portion 12 is, for example, a living room. The roof portion 13 is a gable roof.

[0029] The floor 17 of the first floor space 15 and the floor 18 of the second floor space 16 are both floors set at the normal height for each floor. In other words, these floors 17, 18 are not so-called skip floors.

[0030] The house 10 has an open-ceiling space 19 that spans the first floor 11 and the second floor 12. The open-ceiling space 19 serves as, for example, a living room. The open-ceiling space 19 has an open-ceiling opening 24 formed at the boundary between the first floor 11 and the second floor 12, and opens from the first floor 11 to the second floor 12 through the open-ceiling opening 24. The open-ceiling space 19 is adjacent to the first floor space 15 on the first floor 11, and is adjacent to the second floor space 16 on the second floor 12. The floor 21 of the open-ceiling space 19 is set at the same height as the floor 17 of the first floor space 15.

[0031] A skip floor section 26 is provided above the atrium space 19. The skip floor section 26 is set at an intermediate height between the floor section 18 and the ceiling section 23 in the second floor space 16. In other words, the skip floor section 26 is provided at a height different from the normal floor height in the second floor section 12.

[0032] In the second floor section 12, a storage space 25 is provided above the skip floor section 26. The storage space 25 is separated from the open-ceiling space 19 by the skip floor section 26. This makes the storage space 25 a low-ceiling space with a low ceiling height. The storage space 25 is capable of storing items. The storage space 25 and the open-ceiling space 19 are adjacent to the outdoors, separated by an exterior wall section 32. The open-ceiling space 19 corresponds to the lower space section, and the storage space 25 corresponds to the upper space section.

[0033] The storage space 25 is adjacent to the second floor space 16. An opening 27 that is open to the second floor space 16 is formed in the storage space 25. The opening 27 faces the exterior wall portion 32 across the storage space 25. Access to the storage space 25 from the second floor space 16 is possible through this opening 27. Although not shown, the second floor portion 12 is provided with a ladder or staircase for ascending and descending between the second floor space 16 and the storage space 25.

[0034] A waist wall portion 28 is provided below the opening 27. The waist wall portion 28 is provided across the skip floor portion 26 and the floor portion 18 of the second floor space 16. The waist wall portion 28 faces the outer wall portion 32 with the open-ceiling space 19 in between.

[0035] As shown in FIG. 2 , second floor portion 12 is provided with second floor living space 33 adjacent to storage space 25 and atrium space 19. Second floor living space 33 is adjacent to the outdoors via exterior wall portion 32. Second floor portion 12 of exterior wall portion 32 is provided with light-receiving windows 34 that allow light to enter second floor living space 33. Second floor portion 12 of exterior wall portion 32 is also provided with light-receiving windows 35 that allow light to enter atrium space 19. The floor of second floor living space 33 is set at the same height as floor portion 18 of second floor space 16, and the ceiling of second floor living space 33 is set at the same height as ceiling portion 23 of second floor space 16.

[0036] As described above, the present house 10 is a modular house constructed by combining multiple rectangular parallelepiped building units. The following describes the construction of building unit 40, which is one of the building units that make up the house 10 and is provided with skip floor section 26.

[0037] 3, the building unit 40 has four pillars 41 arranged at its four corners, and four ceiling girders 42 and four floor girders 43 that connect the upper and lower ends of each pillar 41. The pillars 41, ceiling girders 42, and floor girders 43 form a rectangular parallelepiped frame.

[0038] An intermediate floor beam 47 is spanned between the middle sections of the floor girders 43 on the opposing long sides of the floor section of the building unit 40. An intermediate ceiling beam 48 is spanned between the middle sections of the ceiling girders 42 on the long sides of the ceiling section of the building unit 40. The intermediate ceiling beam 48 is located directly above the intermediate floor beam 47 and faces the intermediate floor beam 47 from above and below.

[0039] Although not shown, multiple ceiling joists are installed at predetermined intervals between opposing ceiling girders 42 on the long sides of the building unit 40, and these ceiling joists support the ceiling surface material of the second floor portion 12. Multiple floor joists are installed at predetermined intervals between opposing floor girders 43 on the long sides of the building unit 40, and these floor joists support the floor surface material of the second floor portion 12. Furthermore, in the floor portion of the building unit 40, no floor joists are installed between the intermediate floor joist 47 and the floor joist 43 on one short side. Therefore, a floor opening 49 is formed in the floor portion of the building unit 40, surrounded by the intermediate floor joist 47, the floor joist 43 on the short side, and each floor joist 43 on the long side. The floor opening 49 constitutes the high-rise opening 24.

[0040] The building unit 40 is provided with center columns 51 and 52. The center column 51 is provided straddling the vertically opposing floor beams 43 and ceiling beams 42. The center column 52 is provided straddling the vertically opposing intermediate floor beams 47 and intermediate ceiling beams 48. The center columns 51 are located on both end sides of the floor beams 43, and the center columns 52 are located on both end sides of the intermediate floor beams 47. In this case, each center column 51 and each center column 52 are located at the same position in the longitudinal direction of the floor beams 43, 45.

[0041] A skip floor section 26 is provided between the center columns 51, 52. The skip floor section 26 is configured to include a floor surface material 53 that forms the floor surface of the storage space 25, a ceiling surface material 61 that forms the ceiling surface of the open-ceiling space 19, and a support frame 57 that is provided between the floor surface material 53 and the ceiling surface material 61 and supports the double-sided materials 53, 61.

[0042] The floor surface material 53 is composed of a subfloor surface material 54 and a floor finishing surface material 55. The subfloor surface material 54 is made of rectangular plywood. The floor finishing surface material 55 is made of flooring and is laid on top of the subfloor surface material 54. The ceiling surface material 61 is made of rectangular gypsum board.

[0043] The support frame 57 has a pair of support beams 58 spanning the middle of the opposing center posts 51, 52, and a number of small beams 59 spanning between each of the support beams 58. Each support beam 58 is fixed to the center posts 51, 52. Each support beam 58 and small beam 59 is made of wooden timber and is connected with nails or the like.

[0044] A floor surface material 53 is placed on the upper surface of the support frame 57. The floor surface material 53 is fixed to the support frame 57 with screws or the like. A ceiling surface material 61 is fixed to the underside of the support frame 57 with screws or the like. In addition to the support frame 57, electrical wiring and the like (not shown) are also provided in the space between the floor surface material 53 (subfloor surface material 54) and the ceiling surface material 61.

[0045] Incidentally, it is conceivable to provide light-receiving windows in exterior wall 32 to allow outside light into storage space 25 and atrium space 19. In this case, it is conceivable to provide separate light-receiving windows in second-floor section 12 of exterior wall 32 for storage space 25 and atrium space 19. However, in this case, the height of the light-receiving windows would be significantly smaller than the height of other light-receiving windows 34 also provided in exterior wall 32. In this case, when house 10 is viewed from the outside, the balance between the light-receiving windows would be poor, which could mar the appearance of house 10.

[0046] Therefore, in the house 10 of this embodiment, a light-receiving window 62 is provided in the second floor portion 12 of the exterior wall portion 32, extending vertically across the skip floor portion 26. The configuration of the light-receiving window 62 will be described below with reference to Figures 1, 2, and 4 as appropriate. Note that Figure 4 is a perspective view of the light-receiving window 62 as seen from the storage space 25 side, and for convenience of explanation, the skip floor portion 26 is not shown.

[0047] As shown in Fig. 4, a window opening 63 is formed in the outer wall portion 32. The window opening 63 is a slit-shaped opening that extends vertically and is provided to connect the indoors and outdoors. The window opening 63 extends across the skip floor portion 26 in the vertical direction.

[0048] A light-receiving window section 62 is provided in the window opening 63. The light-receiving window section 62 is arranged closer to the outdoors in the window opening 63 (see FIG. 1). The light-receiving window section 62 is a fixed slit window, and has a window glass 64 and a window frame sash 65. The window glass 64 is formed in the shape of a rectangular plate. The window frame sash 65 is provided on the periphery of the window opening 63, and the window glass 64 is attached inside the window frame sash 65.

[0049] Frame 66 is provided on the indoor side of light-receiving window portion 62 in window opening 63. Frame 66 is arranged on the periphery of window opening 63. Frame 66 has an upper frame portion extending along the upper edge of window opening 63, a lower frame portion extending along the lower edge of window opening 63, and a pair of side frame portions 66a extending along each side edge of window opening 63. Frame 66 corresponds to a window frame.

[0050] As shown in Figures 2 and 4, multiple (specifically, three) daylighting windows 62 are provided side by side. The height dimension of each daylighting window 62 is the same as the height dimension of daylighting window 34. This ensures a balance between each daylighting window 62 and daylighting window 34. Furthermore, daylighting windows 62 (window glass 64) extend across skip floor 26 from top to bottom. This allows daylight to enter storage space 25 and open-ceiling space 19 through daylighting windows 62. This makes it possible to introduce external light into storage space 25 and open-ceiling space 19 while minimizing damage to the appearance of house 10.

[0051] In the configuration of this embodiment, in which the light-receiving window 62 is provided across the skip floor 26 from above and below, it is expected that the skip floor 26 will be visible from the outdoors through the light-receiving window 62. Because the skip floor 26 is configured to include the floor surface material 53 and the ceiling surface material 61, in this case, there is a risk that components such as the support frame 57 and electrical wiring arranged between the floor surface material 53 and the ceiling surface material 61 will also be visible from the outdoors. If this happens, these components, which are normally invisible, will be visible, and this could significantly impair the appearance of the house 10.

[0052] In view of this, in this embodiment, a cover member 71 is provided between the light-receiving window portion 62 and the skip floor portion 26, and the cover member 71 covers and conceals the space between the floor surface material 53 and the ceiling surface material 61. The cover member 71 will be described below with reference to Figures 5 to 7. For ease of explanation, the cover member 71 is indicated by dot hatching in Figures 6 and 7.

[0053] 5 to 7, cover member 71 is configured to have a main body 72, and a first bracket 83 and a second bracket 85 provided on main body 72. Cover member 71 is provided for each light-receiving window 62, and is disposed between each light-receiving window 62 and skip floor 26.

[0054] The main body 72 is formed by bending a steel plate. The main body 72 is configured to have a cover portion 73, an extension portion 74, and a rising portion 78. The entire surface of the main body 72 is painted (colored) black.

[0055] The covering portion 73 extends in the vertical direction and is disposed between the light-receiving window portion 62 and the skip floor portion 26 in the window opening 63. The covering portion 73 is disposed opposite the light-receiving window portion 62 and covers the space between the ceiling surface material 61 and the floor surface material 53 from the light-receiving window portion 62 side. Specifically, the covering portion 73 covers the area from the underside of the ceiling surface material 61 to the vertical middle portion of the floor surface material 53 (specifically, the subfloor surface material 54). This prevents the space between the ceiling surface material 61 and the floor surface material 53 from being seen through the light-receiving window portion 62 from the outdoors. The covering portion 73 is disposed in the indoor-outdoor direction middle portion of the window opening 63 and extends in the width direction (the same direction as the width direction of the light-receiving window portion 62) across each side frame portion 66a of the frame 66. The widthwise length of the covering portion 73 is the same as the spacing between each side frame portion 66a.

[0056] Extension portion 74 extends horizontally from the upper end of cover portion 73 toward light-receiving window portion 62. Extension portion 74 extends to a position where the end on the light-receiving window portion 62 side is close to light-receiving window portion 62. This makes it possible to prevent objects from falling from storage space 25 into open space 19 through the gap between skip floor portion 26 and light-receiving window portion 62. Furthermore, rising portion 78 rises upward from the end of extension portion 74 on the light-receiving window portion 62 side.

[0057] A long rectangular timber 81 is provided on the plate surface of the cover portion 73 facing the skip floor portion 26. The rectangular timber 81 extends along the upper side of the cover portion 73, and more specifically, extends over the entire upper side. The rectangular timber 81 is fixed to the cover portion 73 with a screw 89. The upper surface of the rectangular timber 81 is flush with the upper surface of the extension portion 74.

[0058] The first bracket 83 is attached to the cover portion 73 of the main body 72 via a square bar 81 (see FIG. 5). That is, the first bracket 83 is attached on the opposite side of the square bar 81 from the cover portion 73. The first bracket 83 is formed in an L-shape from a steel plate and has a pair of plate portions 83a, 83b that are perpendicular to each other. Of the plate portions 83a, 83b, one plate portion 83a is fixed to the surface of the square bar 81 opposite the cover portion 73 with a screw 89. The other plate portion 83b extends from the upper end of the plate portion 83a to the side opposite the light-receiving window portion 62 (see FIG. 6). The other plate portion 83b is located higher than the upper surfaces of the extension portion 74 and the square bar 81. A plurality of first brackets 83 (specifically, two) are provided at intervals in the width direction of the cover portion 73 (see FIG. 7).

[0059] The plate portion 83b of the first bracket 83 is placed on the upper surface of the underfloor surface material 54. A recess 54b is formed in the underfloor surface material 54, in which the plate portion 83b is placed. The recess 54b is open upward and toward the light-receiving window 62. With the plate portion 83b placed in this recess 54b, the upper surface of the plate portion 83b and the upper surface of the underfloor surface material 54 are flush with each other. In addition, a screw hole 83c is formed in the plate portion 83b, penetrating it in the thickness direction. A screw 89 is inserted into the screw hole 83c, and the plate portion 83b is fixed to the underfloor surface material 54 by the screw 89. In this way, the first bracket 83, and therefore the cover member 71, are fixed to the skip floor section 26.

[0060] As described above, the floor finishing surface material 55 is laid on the upper surface of the underfloor surface material 54. The plate portion 83b is arranged in a state sandwiched between the floor finishing surface material 55 and the underfloor surface material 54. This makes it possible to make the plate portion 83b invisible from within the storage space 25. The plate portion 83b corresponds to the placing portion.

[0061] The second brackets 85 are provided on both sides of the covering portion 73 in the width direction. Each second bracket 85 is disposed at the bottom of the covering portion 73. Each second bracket 85 is formed in an L-shape from a steel plate and has a pair of plate portions 85a, 85b that are perpendicular to each other. Of each plate portion 85a, 85b, one plate portion 85a is fixed by welding to the plate surface of the covering portion 73 on the skip floor portion 26 side. The other plate portion 85b extends from the plate portion 85a to the side opposite the light-receiving window portion 62 (see FIG. 6). In this case, each plate portion 85b extends from the end of the covering portion 73 in the width direction, i.e., from the side end of the covering portion 73, to the side opposite the light-receiving window portion 62, and is disposed with its plate surfaces facing each other.

[0062] The outer surface of each plate portion 85b abuts against the inner surface of the side frame portion 66a. In this abutting state, each plate portion 85b is fixed to the side frame portion 66a with a screw 89. More specifically, each plate portion 85b has a screw hole 85c formed therethrough in the plate thickness direction, and a screw 89 is inserted into the screw hole 85c. As a result, for the second bracket 85, the cover member 71 is fixed to the frame 66. The plate portion 85b corresponds to a fixing portion.

[0063] A subfloor surface material 76, separate from the subfloor surface material 54, is placed on the upper surfaces of the extension portion 74 and the square timber 81. The subfloor surface material 76 is made of wooden plywood. The subfloor surface material 76 is arranged across the entire upper surface of the extension portion 74 and the upper surface of the square timber 81. The upper surfaces of the subfloor surface materials 54, 76 are flush with each other. A portion of the floor finishing surface material 55 (hereinafter referred to as floor portion 55a) is overlaid on the upper surface of the subfloor surface material 76. A portion of the floor finishing surface material 55 extends further toward the light-receiving window portion 62 than the subfloor surface material 54, and this extended portion forms the floor portion 55a. The floor portion 55a is overlaid on the entire upper surface of the subfloor surface material 76. This allows the upper surfaces of the extension portion 74 and the square timber 81 to be covered and hidden. For the sake of simplicity, the floor finishing surface material 55, floor portion 55a, and underfloor surface material 76 are omitted from the illustration in Figure 7. The floor portion 55a corresponds to "a part of the floor finishing surface material" in the claims.

[0064] A rising portion 78 of main body 72 is disposed closer to light-receiving window 62 than underfloor surface material 76 and floor portion 55a, which are stacked one above the other. The height of rising portion 78 is approximately the same as the sum of the thicknesses of floor portion 55a and underfloor surface material 76 (see FIG. 6). As a result, rising portion 78 conceals floor portion 55a and underfloor surface material 76 from the light-receiving window 62 side. This makes it possible to prevent floor portion 55a and underfloor surface material 76 from being seen through light-receiving window 62 from the outdoors.

[0065] Moreover, cover member 71 generally covers and conceals the area from the underside of ceiling surface material 61 to the upper surface of floor finishing surface material (floor portion 55a) from the side of light-receiving window 62. This makes it possible to make the entire height of skip floor section 26 invisible through light-receiving window 62 from the outside.

[0066] According to the configuration of this embodiment described above in detail, the following excellent effects can be obtained.

[0067] According to the above embodiment, because the light-receiving window 62 extends across the skip floor 26 in the vertical direction, the size of the light-receiving window 62 is not limited by the skip floor 26. This ensures a balance between the light-receiving window 62 and the other light-receiving window 34. Furthermore, because the light-receiving window 62 extends across the skip floor 26 in the vertical direction, it is possible to admit light into both the open-ceiling space 19 and the storage space 25. This makes it possible to introduce external light into both the open-ceiling space 19 and the storage space 25 in a house 10 equipped with the skip floor 26, while minimizing damage to the appearance.

[0068] In the configuration of the above embodiment, in which the light-receiving window 62 is provided across the skip floor 26 from above and below, it is expected that the skip floor 26 will be visible from the outdoors through the light-receiving window 62. Because the skip floor 26 is configured to include the ceiling surface material 61 of the open-ceiling space 19 and the floor surface material 53 of the storage space 25, in this case, there is a risk that components such as the support frame 57 and electrical wiring arranged between the floor surface material 53 and the ceiling surface material 61 will also be visible from the outdoors. If this happens, these components, which are normally invisible, will become visible, and this could significantly impair the appearance of the house 10.

[0069] In view of this, in the above embodiment, a cover member 71 is provided between the light-receiving window 62 and the skip floor 26, and the cover member 71 covers and conceals the space between the floor surface material 53 and the ceiling surface material 61 in the skip floor 26 from the light-receiving window 62 side. This makes it possible to prevent the space between the floor surface material 53 and the ceiling surface material 61 from being seen from the outdoors through the light-receiving window 62, thereby preventing the appearance of the house 10 from being significantly impaired.

[0070] In the above embodiment, the light-receiving window 62 is positioned closer to the exterior of the window opening 63. Therefore, in a configuration in which the light-receiving window 62 spans the skip floor 26 from top to bottom, the light-receiving window 62 and the skip floor 26 are spaced apart. This raises the concern that items in the storage space 25 may fall into the open-ceiling space 19 through the gap between the light-receiving window 62 and the skip floor 26. Therefore, in the above embodiment, the cover member 71 has a covering portion 73 that conceals the gap between the ceiling surface material 61 and the floor surface material 53, and an extension portion 74 that extends from the covering portion 73 toward the light-receiving window 62. In this case, the extension portion 74 covers the gap between the light-receiving window 62 and the skip floor 26. This prevents items in the storage space 25 from falling into the open-ceiling space 19.

[0071] If extension portion 74 is provided between light-receiving window portion 62 and skip floor portion 26, there is a concern that the external light taken in through light-receiving window portion 62 will be blocked by extension portion 74, limiting the amount of light entering the area below extension portion 74, i.e., open-ceiling space 19. According to the above embodiment, extension portion 74 extends from the upper end of cover portion 73. This makes it possible to prevent the extension portion 74 from limiting the amount of light entering open-ceiling space 19. Therefore, light can be more effectively let into open-ceiling space 19.

[0072] According to the above embodiment, the extension portion 74 is covered from above by a part (floor portion 55a) of the floor finishing surface material 55, which prevents the extension portion 74 from spoiling the appearance of the storage space 25. Furthermore, even if the extension portion 74 becomes hot due to sunlight, the occupant can be prevented from touching the extension portion 74.

[0073] According to the above embodiment, floor portion 55a and underfloor surface material 76 placed on the upper surface side of extension portion 74 can be covered and hidden from the side of light-receiving window portion 62 by rising portion 78. This prevents floor portion 55a and underfloor surface material 76 from being seen through light-receiving window portion 62 from the outside, more reliably avoiding damage to the appearance of house 10.

[0074] Furthermore, the rising portion 78 can prevent the floor portion 55a and the underfloor surface material 76 from shifting.

[0075] According to the above embodiment, second bracket 85 extends from the side end of cover portion 73 to the side opposite to light-receiving window portion 62. This makes it possible to make second bracket 85 invisible from the outdoors through light-receiving window portion 62, thereby more reliably preventing the appearance of house 10 from being marred.

[0076] Furthermore, in window opening 63, frame 66 is disposed on the periphery of window opening 63, and light-receiving window 62 is disposed on the outdoor side of frame 66. In the above embodiment, in such a configuration, covering portion 73 is disposed in the inner region surrounded by frame 66, and more specifically, is disposed in the middle of this inner region in the indoor-outdoor direction. This allows second bracket 85 to be fixed to frame 66 even when second bracket 85 extends from the side end of covering portion 73 on the side opposite to light-receiving window 62.

[0077] According to the above embodiment, the cover member 71 has a first bracket 83. The plate portion 83b of the first bracket 83 is placed on the upper surface of the underfloor surface material 54. In this case, the height position of the cover member 71 is determined by the plate portion 83b. This makes it easy to align the cover member 71 when fixing it to the skip floor portion 26.

[0078] Furthermore, the plate portion 83b is disposed in a state sandwiched between the underfloor surface material 54 and the floor finishing surface material 55. As a result, the plate portion 83b is covered from above by the floor finishing surface material 55, and therefore, the appearance of the storage space 25 can be prevented from being marred by the plate portion 83b.

[0079] If cover member 71 is provided between light-receiving window 62 and skip floor 26, there is a concern that cover member 71 (main body 72) may be visible from the outdoors through light-receiving window 62. According to the above embodiment, main body 72 is entirely painted (colored) black. This prevents cover member 71 from being noticeable through light-receiving window 62, more reliably avoiding damage to the appearance of house 10.

[0080] The present invention is not limited to the above-described embodiment, and may be implemented, for example, as follows.

[0081] (1) In the above embodiment, the lower space is an open-ceiling space 19, but this is not limited to this. In other words, the lower space is not limited to one that spans multiple floors. For example, the floor of the lower space may be set at the same height as the floor 18 of the second-floor space 16.

[0082] (2) In the above embodiment, the upper space is the storage space 25, but is not limited to this. For example, it may be a living room.

[0083] (3) In the above embodiment, the skip floor section 26 is provided on the second floor 12 of the house 10, but this is not limiting. For example, a skip floor section may be provided on the first floor of the house. In this case, the ceiling of the upper space section may be set at the same height as the ceiling of the first floor space 15, making the upper space section a low-ceilinged space, or the ceiling of the upper space section may be set at the same height as the ceiling of the second floor space 16, making the upper space section an open-ceiling space.

[0084] (4) In the above embodiment, the cover member 71 is provided between the light-receiving window portion 62 and the skip floor portion 26, but the cover member 71 is not a required component. However, it is preferable to provide the cover member in order to prevent the skip floor portion from spoiling the appearance of the house.

[0085] (5) In the above embodiment, the light-receiving window 62 is a slit window, but this is not limitative. In other words, the width of the light-receiving window is not particularly limited.

[0086] (6) In the above embodiment, one cover member 71 is provided for one light-receiving window 62, but this is not limiting. For example, multiple cover members may be provided side by side for one light-receiving window. In this case, it is preferable to provide the multiple cover members close to each other to prevent the skip floor section from being visible through the gaps between the multiple cover members.

[0087] (7) In the above embodiment, the cover member 71 is composed of the main body 72, the first bracket 83, the second bracket 85, and the square bar 81, but these components do not need to be separate components. In other words, the entire cover member may be formed as a single component.

[0088] (8) The material of the cover member is not particularly limited as long as it has sufficient strength. For example, it may be made of resin.

[0089] (9) In the above embodiment, the entire surface of the main body 72 is colored (painted) black, but this is not limited to this. The entire surface of the main body 72 does not necessarily have to be colored, as long as at least the surface of the cover member facing the light-receiving window is colored. Furthermore, the color is not limited to black. For example, it may be colored a dark color (dark color) such as dark gray or dark blue. Furthermore, the coloring method is not limited to painting the surface. For example, the cover member may be colored a dark color by adding a coloring agent when manufacturing the material.

[0090] (10) In the above embodiment, the cover member 71 is provided with the extension portion 74, but the extension portion 74 is not an essential component. For example, a blocking member separate from the cover member may be provided between the cover member and the light-receiving window portion.

[0091] (11) In the above embodiment, the cover member 71 is provided with the raised portion 78, but the raised portion 78 is not an essential component. However, when a flooring material or the like is placed on the upper surface of the extension portion, it is preferable to provide the raised portion from the viewpoint of ensuring aesthetics. In addition, it is preferable to set the height dimension of the raised portion so that the flooring material or the like can be completely concealed from the light-receiving window side.

[0092] (12) In the above embodiment, the first bracket 83 is attached to the cover portion 73 via the square beam 81, but the square beam 81 is not an essential component. However, because the position of the cover portion 73 in the indoor / outdoor direction can be adjusted using the square beam 81, it is possible to position the cover portion 73 at the middle of the window opening 63 in the indoor / outdoor direction with a simple configuration.

[0093] (13) In the above embodiment, second bracket 85 extends from cover portion 73 to the side opposite light-receiving window portion 62, but this is not limited to this. The fixing portion may extend from the cover portion toward the light-receiving window portion. However, in this case, there is a risk that the fixing portion may be visible through the light-receiving window portion from the outside, so the configuration of the above embodiment is preferred.

[0094] (14) In the above embodiment, the first bracket 83 and the second bracket 85 are provided, but these are not essential components. For example, the cover portion may be fixed to the underside of the subfloor surface material using an L-shaped angle or the like.

[0095] (15) In the above embodiment, the extension 74 extends from the upper end of the cover 73. However, the position where the extension is provided on the cover is not limited to the upper end. However, from the viewpoint of optimally introducing light into the lower space, the configuration of the above embodiment is preferable.

[0096] (16) In the above embodiment, the floor surface material 53 of the skip floor section 26 is composed of the subfloor surface material 54 and the floor finishing surface material 55, but is not limited to this. The floor surface material of the skip floor section may be composed of a single surface material.

[0097] (17) In the above embodiment, the floor portion 55a placed on the upper surface side of the extension portion 74 is part of the floor finishing surface material 55, but this is not limited to this. A different floor surface material adjacent to the floor surface material constituting the skip floor portion may be placed on the upper surface side of the extension portion.

[0098] (18) In the above embodiment, the house 10 is two-story, but is not limited to this. For example, it may be three-story or one-story. Furthermore, while the above embodiment is applied to a modular house, it may also be applied to houses built using other construction methods, such as a steel frame construction method or a traditional wooden construction method.
