[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-20736 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the building structure in Patent Document 1 does not describe the positional relationship between openings such as windows and curtain boxes. In recent years, it has become necessary to provide large-opening ceiling-high sashes around openings to create a connection between indoor and outdoor spaces and make indoor spaces more comfortable. On the other hand, curtain boxes form a visual boundary on the ceiling, which tends to give the impression that the indoor and outdoor spaces are separated.

[0005] Therefore, the object of the present invention is to provide a building structure having a sloped ceiling with a grooved portion such as a ceiling-embedded curtain box, which can give the impression that the lower end of the sloped ceiling is open to the outside, and can create a connection between the indoor space and the outdoor space. [Means for solving the problem]

[0006] The building structure of the present invention comprises an exterior wall provided on the lower side of a sloped ceiling in the slope direction, an opening formed in the exterior wall, a box-shaped groove portion formed at the lower end of the sloped ceiling along the exterior wall and having a lower opening that opens downward, and a mounting portion provided inside the groove portion to which an upper end of a light shielding material that blocks light entering the opening is attached, the groove portion being of a ceiling embedded type that is embedded in the sloped ceiling, and the lower end of the side panel on the opposite side to the opening of the groove portion is lower than the height of the lower surface of the frame on the upper side of the opening. The exterior wall is provided with eaves on the exterior side, and the eaves backing of the eaves is provided with a fire-resistant surface material on the upper side of the decorative eaves backing material, and is parallel to the sloped ceiling, and the end of the eaves backing on the exterior wall side is located at a position higher than the lower end of the sloped ceiling. A shutter box is provided above the opening on the exterior side of the exterior wall, and the upper surface of the shutter box is formed with the same slope as the eaves backing, and the end of the fire-resistant surface material abuts against the side of the shutter box. It is characterized by the following.

[0007] In the building structure of the present invention, the groove portion extends from the lower end of the side panel opposite to the opening toward the lower side of the groove portion. Extend A cover body is formed to cover a portion of the lower opening of the groove, the cover body being flat and having an underside with the same slope as the sloped ceiling.

[0008] The building structure of the present invention is characterized in that the opening has a light-transmitting portion within a rectangular frame, and an upper end of the light-transmitting portion is higher than a lower end of the cover body.

[0009] The building structure of the present invention is characterized in that the cover body is formed of the same material and in the same color as the ceiling material that forms the sloped ceiling.

[0010] In the building structure of the present invention, the cover body forms the sloped ceiling on its base end side. Ceiling material The present invention is characterized in that a parting portion is formed to cover the end surface and part of the bottom surface.

[0011] In the building structure of the present invention, the sloped ceiling is formed by attaching decorative cloth to a base surface formed by a ceiling base material, the groove portion has a pair of side base plates and a top base plate that connects the upper ends of the side base plates, and the groove portion has the same decorative cloth as the sloped ceiling attached to the inner surfaces of the side base plate on the opening side and the top base plate, and the side base plate on the opposite side to the opening forms the sloped ceiling. The ceiling underlayment It is characterized in that it is covered by a decorative side panel that has a parting portion that covers the end surface and part of the bottom surface. Effect of the Invention

[0013] According to the building structure of the present invention, the lower end of the side panel opposite the opening in the groove is formed lower than the height of the underside of the frame above the opening, so that when viewed from inside the building, the opening appears to be located just below the bottom end of the sloped ceiling, and the outdoors can be seen through the opening, giving the impression that the sloped ceiling and the outdoors are connected.

[0014] According to the building structure of the present invention, the groove is formed from the lower end of the side panel opposite the opening toward below the groove, and a cover body is formed to cover part of the downward opening of the groove.The cover body has the same slope as the sloped ceiling, so it can be viewed as an extension of the sloped ceiling.When viewed from the indoor side, the downward opening of the groove is difficult to see, and the opening is viewed as being located just below the tip of the cover body.The outdoors can be seen through the opening, giving the impression that the sloped ceiling is connected to the outdoors.

[0015] According to the building structure of the present invention, since the upper end of the light-transmitting portion of the opening is higher than the lower end of the cover body, the light-transmitting portion can be seen just below the lower end of the cover body, and it appears as if the light-transmitting portion is located just below the cover body extended from the sloped ceiling. The outdoor side can be seen from the tip of the cover body, creating the impression that the sloped ceiling and the outdoors are connected.

[0016] According to the building structure of the present invention, the cover body is made of the same material and is formed in the same color as the ceiling material that forms the sloped ceiling, so that the sloped ceiling and the cover body are seen as a more integrated unit and the tip of the cover body is seen as an extension of the sloped ceiling, giving the impression that the sloped ceiling is more connected to the outdoors.

[0017] According to the building structure of the present invention, a parting portion is formed on the base end side of the cover body that covers the end surface and part of the underside of the ceiling material that forms the sloped ceiling, so that the cover body can also serve as a parting material, thereby improving the design compared to when the cover body is butted against the end surface of the ceiling material.

[0018] According to the building structure of the present invention, the same decorative wallpaper as that of the sloped ceiling is attached to the inside surfaces of the side base plate on the opening side of the groove and the top base plate of the groove, so that the same decorative wallpaper is attached in all positions that are easily visible from the indoor side, and the sloped ceiling and the groove are integrated, thereby maintaining continuity with the outdoors. Also, the decorative upper plate that covers the side base plate on the opposite side of the opening has a parting that covers the end surface and part of the underside of the ceiling material that forms the sloped ceiling, so that a parting is formed without providing cloth in the part where the sloped ceiling and the side plate form an acute angle, and it is possible to prevent the cloth from coming off.

[0019] According to the building structure of the present invention, the eaves underside of the eaves formed on the outdoor side of the exterior wall is arranged parallel with the same gradient as the sloped ceiling, and the end of the eaves underside on the exterior wall side is arranged at a higher position than the lower end of the sloped ceiling, so that the indoor and outdoor can be more unified when viewed from the indoor side. Also, the fireproof surface material arranged on the upper side of the decorative eaves backing material provided on the eaves underside forms a fireproof line by abutting against the side of the shutter box, and at the position where the shutter box ends, the upper surface of the shutter box is formed with the same gradient as the eaves underside, so that the side edge of the fireproof surface material abuts against the side of the shutter box to form a fireproof line.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] First Embodiment The building structure 1a of the first embodiment will be described below with reference to FIG. 1 to FIG. 3. The building structure 1a of the present embodiment is, for example, a two-story wooden detached house. The building structure 1a of the present invention is not limited to wooden construction, and may be a building structure 1a used in buildings made of steel frame or reinforced concrete. The building structure 1a of the present invention is not limited to detached houses, and may be an apartment building or a building other than a house. The building structure 1a is not limited to two-story buildings, and may be a one-story building or a building with three or more stories. The building structure 1a of the present embodiment includes an indoor sloped ceiling 2, eaves 3 whose eaves 4 slopes parallel to the sloped ceiling 2, and an exterior wall 6 formed at the boundary between the sloped ceiling 2 and the eaves 4 and having an opening 5. In this embodiment, the sloped ceiling 2 and the opening 5 are formed on the second floor, which is the top floor of the building, and the eaves 3 are arranged continuously from the roof (not shown). The sloped ceiling 2 and the opening 5 are not necessarily limited to those formed on the top floor. The eaves 3 are not limited to being arranged continuously from the roof, but may be arranged to protrude from the exterior wall 6 of a floor lower than the top floor. The sloped ceiling 2 and the opening 5 of the building structure 1a may be installed on any floor other than the top floor.

[0022] As shown in Figure 1, the sloped ceiling 2 is formed as follows. First, a rafter support (not shown) is hung from the slope beam 7, and a steel rafter 8 is fixed parallel to the slope of the sloped ceiling 2. Then, a ceiling base plate 9 consisting of two gypsum boards is attached to the steel rafter 8. After that, a horizontally extending rafter 10 is attached to the ceiling base plate 9, and a wooden ceiling material 11 is attached underneath, forming the sloped ceiling 2. The slope beam 7 is installed between a ridge beam (not shown) and an eaves beam 12 that is located inside the exterior wall 6 and above the opening 5.

[0023] In addition, rafters 13 are fixed to the upper surface of the slope beams 7, and sheathing boards, roofing materials, and roof materials (not shown) are placed on top of the rafters 13 to form the roof of the building.

[0024] An outer wall 6 is formed on the lower side of the slope direction of the sloped ceiling 2, and an opening 5 is formed in the outer wall 6. A box-shaped groove 15 having a lower opening 14 that opens downward is formed at the lower end of the sloped ceiling 2 along the outer wall 6 at the position where the opening 5 is formed. An attachment part 17 for fixing the upper end of the roll screen 16 is formed inside the groove 15. The roll screen 16 has a sheet-like screen body, a winding part that can wind and pull out the screen body, and an attachment part 17 for attaching the winding part to the decorative upper plate 20 of the groove 15. The roll screen 16 is a light shielding material that is arranged on the indoor side of the opening 5 and blocks external light and lines of sight entering from the opening 5. The light shielding material of the present invention is not limited to the roll screen 16, and may be other light shielding materials such as curtains and blinds.

[0025] The groove portion 15 is formed as a base groove by a pair of side base boards 18 made of gypsum boards and an upper surface base board 19 connecting the upper ends of the pair of side base boards 18. The groove portion 15 is formed by attaching a decorative upper board 20 to the lower surface of the upper surface base board 19, attaching a first decorative side board 21 to the side base board 18 on the side away from the opening 5, and attaching a second decorative side board 22 to the side base board 18 on the opening 5 side. The decorative upper board 20, the first decorative side board 21, and the second decorative side board 22 are preferably formed of the same material and color as the ceiling material 11. For example, when the ceiling material 11 is made of uncolored wood, the decorative upper board 20, the first decorative side board 21, and the second decorative side board 22 are preferably also made of uncolored wood. The decorative top panel 20, the first decorative side panel 21, and the second decorative side panel 22 form the inner surface of the groove portion 15, and are hidden from the view from inside the room and are hardly visible, so they may be made of a material or have a color different from that of the ceiling material 11. The lower end of the first decorative side panel 21 of the groove portion 15 is arranged so as to be lower than the height of the lower surface of the frame 23 above the opening 5.

[0026] A cover body 24a is fixed to the lower end of the first decorative side panel 21 of the groove portion 15. The cover body 24a is flat and extends from the lower end of the first decorative side panel 21 downward from the groove portion 15 at the same gradient as the sloped ceiling 2. A parting portion 25 is formed at the base end of the cover body 24a so as to cover a part of the end surface and the lower surface of the ceiling material 11 forming the sloped ceiling 2. The cover body 24a is formed by stacking a plurality of plates, and the parting portion 25 of the cover body 24a is formed so that the upper side protrudes upward in the gradient direction and abuts against the upper surface of the ceiling material 11, playing the role of a board edging 10 that fixes the ceiling material 11 to the ceiling base plate 9 of the gypsum board at a distance. The lower end face of the parting portion 25 of the cover body 24a is butted against the end face of the ceiling material 11, and the lower part of the lower end face protrudes slightly upward in the gradient direction to form a groove, covering the end face and part of the lower face of the ceiling material 11. The tip of the cover body 24a extends horizontally so as to cover more than half of the lower opening 14 of the groove portion 15. As a result, when viewed from the indoor side, the inside of the groove portion 15 is hidden by the cover body 24a and cannot be seen, and it is visually recognized as if the opening 5 is installed directly from the tip of the cover body 24a.

[0027] The cover body 24a is preferably made of the same material and color as the ceiling material 11 that forms the sloped ceiling 2. Here, for example, if the ceiling material 11 is made of wood, the cover body 24a is preferably made of the same type of wood. Also, if the ceiling material 11 is uncolored, the cover body 24a is preferably uncolored, and if the ceiling material 11 is colored, the cover body 24a is preferably colored the same color. Note that the cover body 24a is not limited to this, and may be made of a different material or color as long as it appears integrated with the ceiling material 11 when viewed from the indoor side without impairing the color scheme or design.

[0028] The opening 5 formed in the outer wall 6 is formed by a plurality of shoji screens 29 each consisting of a rectangular frame 27 and a light-transmitting portion 28, a sash frame 30 that houses the shoji screens 29 so that they can be slid apart, and a frame 23 formed on the indoor side of the sash frame 30 and serving as a border material with the inner wall material. The sash frame 30 is, for example, a full-flat sash whose lower end is flush with the floor surface (not shown). The frame 23 is formed on the side edge and upper edge of the indoor side of the opening 5, and the lower edge of the opening 5 is directly connected to the sash frame 30 whose floor material is full flat (not shown). The sash frame 30 of the opening 5 is not limited to a full-flat sash whose lower end is flush with the floor surface, and may be, for example, a sash frame of a waist window whose lower end of the sash frame 30 is at waist height. When the sash frame 30 is at waist height, the frame 23 is formed not only on the side edges and upper edge on the indoor side of the opening 5, but also on the lower edge on the indoor side of the opening 5. The light-transmitting portion 28 of the shoji 29 is a glass plate, and the rectangular frame 27 is formed with the light-transmitting portion 28 supported by a glazing channel 31 within an aluminum frame.

[0029] As shown in FIG. 3, the light-transmitting portion 28 is disposed so that its upper end is higher than the tip of the cover body 24a. Specifically, the tip of the cover body 24a is lower than the upper end of the visible position of the glass plate forming the light-transmitting portion 28, i.e., the lower end of the glazing channel 31 supporting the upper end of the glass plate. The distance α between the lower end of the upper glazing channel 31 and the lowest position of the cover body 24a is, for example, 20 to 30 mm. However, this dimension is not limited to this. Therefore, when viewed from the indoor side, the frame 23 of the opening 5, the sash frame 30, and the rectangular frame 27 of the shoji screen 29 are difficult to see due to the cover body 24a, so that the light-transmitting portion 28 is visible just below the tip of the cover body 24a, and the outdoor is visible through the light-transmitting portion 28. This makes it possible to make the indoor space an open space with a wide view.

[0030] The eaves 3 formed on the exterior side of the exterior wall 6 are supported by rafters 13 that are erected on a ridge beam and eaves beams 12 (not shown) and protrude from the eaves beams 12 to the exterior side. Although not shown, sheathing boards, roofing materials, and roofing materials are arranged on the rafters 13 and are arranged continuously from the roof of the building. A rafter 33 is fixed below the rafters 13 via a purlin material 32, a fireproof surface material 34 is attached to the rafter 33, and a decorative eaves back material 35 that forms the eaves back 4 is arranged on the fireproof surface material 34 via a board eaves back 10. The fireproof surface material 34 and the decorative eaves back material 35 are parallel to the indoor sloped ceiling 2, and the end of the eaves back 4 on the exterior wall 6 side is arranged at a position higher than the lower end of the sloped ceiling 2.

[0031] A shutter box 36 is provided on the outdoor side of the exterior wall 6 above the opening 5. The shutter box 36 is formed so that a part of the upper surface has the same slope as the eaves 4, and is arranged so that the lower surface of the shutter box 36 is above the opening 5 without interfering with the rafters 13. The upper end of the fireproof surface material 34 abuts against the outdoor side of the shutter box 36, and the fireproof surface material 34 and the shutter box 36 form a fireproof line at the end of the eaves 4. As shown in FIG. 2, the shutter box 36 is interrupted at a position where the opening 5 is not provided, and the side edge of the fireproof surface material 34 abuts against the side of the shutter box 36 while abutting against the surface of the exterior wall 6, forming a fireproof line.

[0032] Second Embodiment Next, the building structure 1b of the second embodiment will be described with reference to FIG. 4. The same components as those of the building structure 1a of the first embodiment will be denoted by the same reference numerals and will not be described. The building structure 1b of the second embodiment has a sloped ceiling 2, an opening 5, and an eaves 3, as in the first embodiment. Along the outer wall 6 at the position where the opening 5 of the sloped ceiling 2 is formed, a box-shaped groove portion 15 having a lower opening 14 that opens downward is formed at the lower end of the sloped ceiling 2. The groove portion 15 has two curtain rails 38 inside. In this embodiment, the two curtain rails 38 are mounting portions that fix the upper end of the light shielding material. In this embodiment, the curtain 37 hung from the curtain rail 38 corresponds to the light shielding material in the present invention. In addition, when the groove portion 15 of this embodiment is to be fitted, the light shielding material is not limited to the curtain 37, and may be a roll screen or other light shielding material that can block external light and lines of sight from the outside. If the light shielding material is not a curtain 37, the attachment portion is not the curtain rail 38 but another member to which the upper end of the light shielding material can be fixed.

[0033] The groove portion 15 is formed by a pair of side base boards 18 made of gypsum board and an upper base board 19 connecting the upper ends of the pair of side base boards 18, forming a base groove, and a decorative upper board 20 is attached to the underside of the upper base board 19, a first decorative side board 21 is attached to the side base board 18 on the side facing away from the opening 5, and a second decorative side board 22 is attached to the side base board 18 on the opening 5 side. As in the first embodiment, the decorative upper board 20, first decorative side board 21, and second decorative side board 22 are preferably formed of the same material and color as the ceiling material 11.

[0034] A cover body 24b is fixed to the lower end of the first decorative side panel 21 of the groove portion 15. The cover body 24b in this embodiment is formed to protrude slightly downward from the lower end of the first decorative side panel 21 with the same gradient as the sloped ceiling 2. In order to avoid interference with the curtain 37 hung from the two curtain rails 38 in the groove portion 15, the protruding length of the cover body 24b is formed shorter than that of the first embodiment. The cover body 24b has a parting portion 25 formed so as to cover the end surface and part of the lower surface of the ceiling material 11 forming the sloped ceiling 2. The cover body 24b is preferably made of the same material and color as the ceiling material 11 forming the sloped ceiling 2. The lower end of the cover body 24b is formed lower than the lower surface of the upper frame 23 formed in the opening 5.

[0035] The eaves 3 and the shutter box 36 formed on the outdoor side of the exterior wall 6 have the same configuration as in the first embodiment, and therefore a description thereof will be omitted.

[0036] Third Embodiment Next, the building structure 1c of the third embodiment will be described with reference to FIG. 5 and FIG. 6. Note that the same components as those of the building structures 1a and 1b of the first and second embodiments are given the same reference numerals and will not be described. The building structure 1c of the third embodiment has a sloped ceiling 2, an opening 5, and an eaves 3, as in the first and second embodiments, and a box-shaped groove portion 15 having a lower opening 14 that opens downward is formed at the lower end of the sloped ceiling 2 along the outer wall 6 at the position where the opening 5 of the sloped ceiling 2 is formed. The groove portion 15 has two curtain rails 38 inside, as in the second embodiment. In this embodiment, the two curtain rails 38 are mounting parts that fix the upper end of the light shielding material. In this embodiment, the curtain 37 hung from the curtain rail 38 corresponds to the light shielding material in the present invention. Note that, when the groove portion 15 of this embodiment is to be fitted, the light shielding material is not limited to the curtain 37, and may be a roll screen or other light shielding material that can block external light and lines of sight from the outside. If the light shielding material is not a curtain 37, the attachment portion is not the curtain rail 38 but another member to which the upper end of the light shielding material can be fixed.

[0037] The sloped ceiling 2 is formed as follows. First, a joist support (not shown) is hung from the slope beams 7, and a steel joist 8 is fixed parallel to the slope of the sloped ceiling 2. Then, a ceiling base plate 9 made of two gypsum boards is attached to the steel joist 8. Then, decorative wallpaper 39 is attached to the underside of the ceiling base plate 9 to form the sloped ceiling 2.

[0038] The groove 15 is formed by a pair of side base plates 18 made of gypsum boards and an upper base plate 19 connecting the upper ends of the pair of side base plates 18. The same decorative wallpaper 39 as the sloped ceiling 2 is attached to the inner surfaces of the groove 15 of the side base plate 18 and the upper base plate 19 on the opening 5 side. A decorative side plate 40 is attached to the inner surface of the groove 15 of the side base plate 18 on the opposite side to the opening 5. The decorative side plate 40 has an end of the ceiling base plate 9 forming the sloped ceiling 2 inserted therein, and a groove-shaped parting portion 26 covering the end surface and part of the lower surface of the ceiling base plate 9 is formed. The decorative side plate 40 is preferably of a texture and color similar to the decorative wallpaper 39 forming the sloped ceiling 2.

[0039] The same decorative cloth 39 as that of the sloped ceiling 2 is attached to the inner surface of the side base plate 18 on the opening 5 side of the groove 15 and the upper surface base plate 19 of the groove 15, so that when the inside of the groove 15 is seen from the indoor side, the same decorative cloth 39 is attached to all positions that are easily visible, and the sloped ceiling 2 and the groove 15 are integrated. This prevents the groove 15 from emphasizing the boundary between the indoors and outdoors, and maintains the continuity between the indoors and outdoors. In addition, a decorative side panel 40 is attached to the inner surface of the groove 15 of the side base plate 18 on the opposite side of the opening 5, and a parting portion 26 that covers the end surface and part of the underside of the ceiling material 11 of the sloped ceiling 2 is formed on this decorative side panel 40, so that the position where the sloped ceiling 2 and the groove 15 butt together is an acute angle, but the parting portion 26 is formed without providing the decorative cloth 39, and the end of the decorative cloth 39 can be neatly fitted while suppressing the cutting of the decorative cloth 39.

[0040] As shown in FIG. 6, the lower end of the decorative side panel 40, which is the side panel on the opposite side of the opening 5 of the groove portion 15, is formed lower than the height of the lower surface of the frame 23 above the opening 5. The distance β between the frame 23 above the opening 5 and the lower end of the decorative side panel 40 is, for example, about 20 to 30 mm. However, this dimension is not limited to this. As a result, when viewed from the indoor side, the opening 5 appears to be located just below the lower end of the sloped ceiling 2, and the outdoor side can be seen through the opening 5, giving the impression that the sloped ceiling 2 and the outdoors are connected, making the view from the indoor side clearer.

[0041] The eaves 3 and the shutter box 36 formed on the outdoor side of the exterior wall 6 have the same configuration as in the first embodiment, and therefore a description thereof will be omitted.

[0042] It goes without saying that the embodiment of the present invention is not limited to the above-mentioned embodiment, and can be modified as appropriate without departing from the scope of the concept of the present invention. [Industrial Applicability]

[0043] The building structures 1a, 1b, and 1c according to the present invention are suitable as a residential building structure 1 that allows the view of the outdoors to be enjoyed from inside the building. [Explanation of symbols]
