Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above prior art, since the board-shaped heat insulating material is sandwiched between the outer wall panel and the inner wall panel, it is difficult to arrange wiring or the like between the vertical remnants of the inner wall frame and the vertical rails of the outer wall frame.

[0005] In consideration of the above facts, an object of the present invention is to obtain a heat insulation structure of a building that can arrange wiring or the like between the vertical remnants of the inner wall frame and the vertical rails of the outer wall frame while ensuring the heat insulation performance of the building.

Means for Solving the Problems

[0006] The thermal insulation structure of a building according to the first embodiment includes: an interior wall material constituting the wall surface of the interior wall of the building; an interior wall frame arranged along the periphery of the interior wall material and configured in a rectangular frame shape including a first upper horizontal bar, a first lower horizontal bar, and a pair of first vertical bars, and fixed to the ceiling and floor; an exterior wall frame arranged on the exterior side of the interior wall frame at a predetermined distance from the interior wall frame and configured in a rectangular frame shape including a second upper horizontal bar, a second lower horizontal bar, and a pair of second vertical bars that overlap with the first vertical bars when viewed from the thickness direction of the interior wall material, and fixed to the ceiling and floor; a first thermal insulation section partially contained within the interior wall frame; a second thermal insulation section partially contained within the exterior wall frame and located on the exterior side of the first thermal insulation section; and a third thermal insulation section attached to the interior wall frame side of the vertical bars of the exterior wall frame and configured with a fibrous thermal insulation material wrapped inside.

[0007] In the first embodiment of the building's thermal insulation structure, the interior wall surface of the building is composed of interior wall material. The interior wall frame is configured in a rectangular frame shape, including a first upper horizontal bar, a first lower horizontal bar, and a pair of first vertical bars, each positioned along the periphery of the interior wall material. The interior wall frame is fixed to the ceiling and the floor.

[0008] Furthermore, an exterior wall frame is positioned on the exterior side of the interior wall frame. This exterior wall frame is constructed in a rectangular frame shape, including a second upper horizontal bar, a second lower horizontal bar, and a pair of second vertical bars that overlap with the first vertical bar when viewed from the thickness direction of the interior wall material. The exterior wall frame is fixed to the ceiling and floor.

[0009] Furthermore, this embodiment includes a first insulation section that is partially housed within the inner wall frame and a second insulation section that is partially housed within the outer wall frame and located on the outdoor side of the first insulation section, thereby suppressing heat transfer between the outdoor and indoor sides.

[0010] Incidentally, a configuration in which there is no insulation between the first vertical battens of the interior wall frame and the second vertical battens of the exterior wall frame is undesirable from the standpoint of ensuring the building's thermal insulation performance.

[0011] In this regard, for example, a configuration in which board-shaped insulation material is placed between the first and second vertical battens can be considered, but if such a configuration is adopted, it becomes difficult to place wiring, etc., between the first and second vertical battens.

[0012] In this embodiment, a third insulation section is attached to the inner wall frame side of the second vertical batten of the outer wall frame, and this third insulation section is constructed by packaging a fibrous insulation material.

[0013] Therefore, in this embodiment, the space between the first vertical beam and the second vertical beam can be filled with the third insulation section. Furthermore, when arranging wiring or the like between the first vertical beam and the second vertical beam, the third insulation section can be deformed to secure space for arranging the wiring or the like.

[0014] The thermal insulation structure of a building according to the second embodiment is configured such that, in the thermal insulation structure of a building according to the first embodiment, the interior wall frame includes an interior interior wall frame that constitutes the indoor side and an exterior interior wall frame that constitutes the outdoor side, and the first thermal insulation section includes an interior thermal insulation section that constitutes the indoor side of the first thermal insulation section and is mainly housed within the interior interior wall frame and is packaged with fibrous thermal insulation material, and an exterior thermal insulation section that constitutes the outdoor side of the first thermal insulation section and is mainly housed within the exterior interior wall frame and is packaged with fibrous thermal insulation material.

[0015] In the second embodiment of the building's thermal insulation structure, the interior wall frame comprises an interior wall frame that constitutes the indoor side and an exterior wall frame that constitutes the outdoor side. Furthermore, the first thermal insulation section comprises an interior thermal insulation section that constitutes its indoor side and is mainly housed within the interior wall frame and is constructed of fibrous thermal insulation material, and an exterior thermal insulation section that constitutes its outdoor side and is mainly housed within the exterior wall frame and is constructed of fibrous thermal insulation material.

[0016] Therefore, in this aspect, a heat insulation layer including an inner inner wall frame and an inner heat insulation part and a heat insulation layer including an outer inner wall frame and an outer heat insulation part are formed in a building, and the heat insulation performance of the building can be ensured. Further, by making the inner inner wall frame and the inner heat insulation part common with those used in, for example, a building having a single heat insulation layer, the efficiency of parts management can be improved.

[0017] In the heat insulation structure of a building according to the third aspect, in the heat insulation structure of the building according to the second aspect, the second heat insulation part is attached to the outdoor side surface of the outer inner wall frame.

[0018] In the heat insulation structure of a building according to the third aspect, the second heat insulation part is attached to the outdoor side surface of the outer inner wall frame, and the second heat insulation part and the third heat insulation part can be brought into close contact with each other to improve the heat insulation performance of the building.

Effect of the Invention

[0019] As described above, the heat insulation structure of a building according to the invention of the present application has an excellent effect that wiring or the like can be arranged between the vertical members of the inner wall frame and the vertical rails of the outer wall frame while ensuring the heat insulation performance of the building.

Mode for Carrying Out the Invention

[0021] Hereinafter, an example of a building to which the heat insulation structure of a building according to an embodiment of the present invention is applied will be described with reference to FIGS. 1 to 4.

[0022] First, the overall structure of the "building 10" according to the present embodiment will be described. As shown in FIG. 4, the building 10 according to the present embodiment is configured by installing a plurality of building units 12 on a foundation (not shown).

[0023] The body frame 14 that constitutes the body of the building unit 12 includes columns (not shown) erected at the four corners, a ceiling frame 16 that connects the upper ends of the columns, and a floor frame 18 that connects the lower ends of the columns, as partially shown in FIG. 1. The ceiling frame 16 is configured such that a ceiling girder 20 made of channel steel and a ceiling girder (not shown) shorter than the ceiling girder 20 are arranged in a rectangular frame shape, and a plurality of ceiling joists (not shown) are spanned between the ceiling girders 20 at a predetermined interval.

[0024] Also, the floor frame 18 has the same configuration as the ceiling frame 16. Specifically, the floor frame 18 is configured such that a floor girder 22 made of channel steel and a floor girder (not shown) shorter than the floor girder 22 are arranged in a rectangular frame shape, and a plurality of ceiling joists (not shown) are spanned between the floor girders 22 at a predetermined interval.

[0025] Then, a "ceiling 28" is formed including a ceiling base material 24 and a ceiling material 26 located on the lower side in the building height direction of the ceiling frame 16, and a "floor 34" is formed including a floor base material 30 and a floor material 32 located on the upper side in the building height direction of the floor frame 18.

[0026] To describe the structure of the ceiling 28 in more detail, a ceiling base material 24 made of board material is positioned in contact with the lower surface of the lower flange portion 20B of the ceiling main beam 20, which is positioned with its web portion 20A facing the outside. A predetermined number of rectangular flat ceiling materials 26 are laid on the lower surface 24A of the ceiling base material 24, with their outdoor ends spaced at a predetermined distance from the outdoor periphery of the lower surface 24A toward the inside of the building, along the longitudinal direction (girder direction) of the building unit 12. The finished surface of the ceiling material 26 is covered with ceiling cloth for ceiling finishing, which is not shown.

[0027] Meanwhile, in the floor 34, a floor subfloor 30 formed from rectangular cross-section timbers is positioned in contact with the upper surface of the upper flange portion 22B of the floor main beam 22, which is positioned with its web portion 22A facing the outside. On the upper surface 30A of the floor subfloor 30, a predetermined number of rectangular flat floor materials 32 are laid along the longitudinal direction of the building unit 12, with their outdoor ends spaced at a predetermined distance from the outdoor periphery of the upper surface 30A toward the inside of the building. A floor finishing material (not shown) is laid on the finished surface of the floor materials 32.

[0028] Furthermore, multiple exterior wall panels 36 are attached to the outdoor side of the ceiling beams 20 and floor beams 22, arranged in a row along the longitudinal direction of the building unit 12, and these exterior wall panels 36 constitute a part of the exterior wall 38 of the building 10.

[0029] This exterior wall panel 36 is composed of a rectangular frame-shaped "exterior wall frame 40" and a rectangular flat exterior wall material 48, and is arranged with its width direction aligned with the longitudinal direction of the building unit 12.

[0030] The exterior wall frame 40 is composed of a pair of second vertical bars 42 extending in the building height direction, a second upper horizontal bar 44 spanning between the upper ends of the vertical bars 42, and a second lower horizontal bar 46 spanning between the lower ends of the vertical bars 42. Specifically, the vertical bars 42 are made of channel steel, and their web portion 42A is positioned on the outside in the width direction of the exterior wall panel 36.

[0031] Furthermore, insulation material is attached to the indoor flange portion 42B of the vertical batten 42, as will be described later, and exterior wall material 48 is attached to the outdoor flange portion 42C of the vertical batten 42.

[0032] On the other hand, the upper horizontal bar 44 is made of channel steel, and its web portion 44A is positioned on the lower side in the building height direction. The exterior wall material 48 is attached to the outdoor flange portion 44B of the upper horizontal bar 44.

[0033] Furthermore, multiple weld nuts 56 are provided at various locations in the width direction of the exterior wall panel 36 on the outdoor side of the indoor flange portion 44C of the upper horizontal bar 44, and insertion holes (not shown) corresponding to the weld nuts 56 are formed in the web portion 20A of the ceiling beam 20. Then, the upper side of the exterior wall frame 40 in the building height direction is fixed to the ceiling beam 20 by screwing bolts 52 into the weld nuts 56 from the indoor side of the web portion 20A of the ceiling beam 20.

[0034] The lower horizontal bar 46 is composed of a web portion 46A that extends in the width direction of the exterior wall panel 36 and a flange portion 46B that extends downward in the building height direction from the outdoor peripheral edge of the web portion 46A, and the exterior wall material 48 is attached to the flange portion 46B.

[0035] Furthermore, a bracket 54 extending in the width direction of the exterior wall panel 36 is attached to the web portion 46A of the lower horizontal bar 46. This bracket 54 is composed of an upper wall portion 54A positioned along the lower surface of the web portion 46A and joined to the web portion 46A by a joint (not shown), such as welding, and a side wall portion 54B extending downward in the building height direction from the indoor peripheral edge of the upper wall portion 54A.

[0036] Furthermore, a weld nut 56 is provided on the outdoor side of the side wall portion 54B, and an insertion hole (not shown) corresponding to the weld nut 56 is formed in the web portion 22A of the floor beam 22. Then, a bolt 58 is screwed into the weld nut 56 from the indoor side of the web portion 22A of the floor beam 22, thereby fixing the lower side of the exterior wall frame 40 in the building height direction to the floor beam 22.

[0037] In this embodiment, the thermal insulation structure of the building according to this embodiment is applied primarily to the "interior wall 60" of the building unit 12. The thermal insulation structure of the building 10, which is the main part of this embodiment, will be described in detail below.

[0038] As shown in Figures 2 and 3, the interior wall 60 is composed of multiple interior wall panels 61 connected in the longitudinal direction of the building unit 12, and each interior wall panel 61 is composed of an "interior wall frame 62" that forms its skeleton and an "interior wall material 64" that forms the "wall surface 60A" on the indoor side of the interior wall 60.

[0039] The interior wall frame 62 comprises an "interior interior wall frame 66" that constitutes its indoor side and an "exterior interior wall frame 68" that constitutes its outdoor side. The interior interior wall frame 66 is constructed in a rectangular frame shape with the building height direction as its longitudinal direction, including a rectangular upper horizontal bar 70 made of wood and extending in the longitudinal direction of the building unit 12, a rectangular lower horizontal bar 72 made of wood and extending in the longitudinal direction of the building unit 12, and a pair of rectangular vertical bars 74 made of wood and extending in the building height direction. The upper horizontal bar 70 is positioned to fit between the upper ends 74A of the vertical bars 74, and both ends are fixed to the upper ends 74A by mounting members such as nails (not shown).

[0040] On the other hand, the lower horizontal bar 72 is positioned to fit between the lower ends 74B of the vertical bars 74, and both ends are fixed to the lower ends 74B by mounting members such as nails (not shown). The inner wall frame 66 may be configured such that the upper horizontal bar 70 is positioned above the upper end 74A of the vertical bars 74 in the building height direction, or the lower horizontal bar 72 is positioned below the lower end 74B of the vertical bars 74 in the building height direction. The lengths of the upper horizontal bar 70, lower horizontal bar 72, and vertical bars 74 in the thickness direction of the inner wall material 64 are set to approximately the same dimensions, and these lengths can be considered as the thickness of the inner wall frame 66.

[0041] Furthermore, an interior wall material 64, made of rectangular flat gypsum board, is attached to the interior wall frame 66 from the indoor side using mounting members such as nails (not shown). The upper horizontal rail 70 is positioned along the upper peripheral edge of the interior wall material 64 in the building height direction, and the lower horizontal rail 72 is positioned along the lower peripheral edge of the interior wall material 64 in the building height direction. In addition, the vertical rail 74 is positioned along the peripheral edge of the interior wall material 64 that extends in the building height direction. The interior wall material 64 is covered with interior wall cloth (not shown) for interior wall finishing.

[0042] On the other hand, the outer interior wall frame 68 is constructed in a rectangular frame shape that overlaps with the inner interior wall frame 66 when viewed from the thickness direction of the interior wall material 64. This includes a rectangular upper horizontal bar 76 made of wood and extending in the longitudinal direction of the building unit 12, a rectangular lower horizontal bar 78 made of wood and extending in the longitudinal direction of the building unit 12, and a pair of rectangular vertical bars 80 made of wood and extending in the height direction of the building. Furthermore, the upper horizontal bar 76 is positioned to fit between the upper ends 80A of the vertical bars 80, and both ends of the upper horizontal bar 76 are fixed to the upper ends 80A by mounting members such as nails (not shown).

[0043] On the other hand, the lower horizontal bar 78 is positioned to fit between the lower ends 80B of the vertical bars 80, and both ends are fixed to the lower ends 80B by mounting members such as nails (not shown). The outer interior wall frame 68 may be configured such that the upper horizontal bar 76 is positioned above the upper end 80A of the vertical bars 80 in the building height direction, or the lower horizontal bar 78 is positioned below the lower end 80B of the vertical bars 80 in the building height direction. The thickness of the interior wall material 64 of the upper horizontal bar 76, lower horizontal bar 78, and vertical bars 80 is set to approximately the same dimensions, and this length can be considered as the thickness of the outer interior wall frame 68. Furthermore, the thickness of the outer interior wall frame 68 is set to be about 3 to 4 times the thickness of the inner interior wall frame 66.

[0044] As shown in Figure 1, the upper horizontal bar 70 of the inner wall frame 66 is attached to the upper horizontal bar 76, and the lower horizontal bar 72 of the inner wall frame 66 is attached to the lower horizontal bar 78, respectively, by mounting members such as nails 82, so that the inner wall frame 66 and the outer wall frame 68 are integrated. Furthermore, in the following, in the inner wall frame 62, the assembly of the upper horizontal bar 70 and the upper horizontal bar 76 will be referred to as the first upper horizontal bar, the assembly of the lower horizontal bar 72 and the lower horizontal bar 78 will be referred to as the first lower horizontal bar, the assembly of the vertical bar 74 and the vertical bar 80 will be referred to as the first vertical bar, the "vertical bar 62C".

[0045] Furthermore, the outer interior wall frame 68 is supported by a wooden ceiling framing material 84 at the top of the upper horizontal batten 76, and by a wooden floor framing material 86 at the bottom of the lower horizontal batten 78.

[0046] More specifically, the ceiling framing material 84 is positioned on the indoor side of the ceiling framing material 24, at a predetermined distance from the ceiling framing material 24. This ceiling framing material 84 extends in the longitudinal direction of the building unit 12 and is formed from rectangular timbers. It is positioned along the upper surface of the ceiling material 26 in the building height direction and is attached to the ceiling material 26 by mounting members (not shown).

[0047] Then, mounting members such as nails 88 are driven into the ceiling 28 from the lower side of the upper horizontal bar 76 in the building height direction toward the ceiling framing material 84, thereby fixing the upper horizontal bar 76 to the ceiling 28.

[0048] On the other hand, the underfloor subflooring material 86 is positioned on the indoor side of the underfloor subflooring material 30, at a predetermined distance from the underfloor subflooring material 30. This underfloor subflooring material 86 extends in the longitudinal direction of the building unit 12 and is formed of rectangular cross-section timbers. It is positioned along the lower surface of the floor material 32 in the building height direction and is attached to the floor material 32 by mounting members (not shown).

[0049] Then, mounting members such as nails 89 are driven into the floor underlayment 86 from the upper side of the lower horizontal bar 78 in the building height direction, thereby fixing the lower horizontal bar 78 to the floor 34. In other words, the interior wall frame 62 is fixed to the ceiling 28 and the floor 34.

[0050] Furthermore, in this embodiment, as shown in Figure 3, an "insulating material 90" as an inner insulating section, an "insulating material 92" as an outer insulating section, an "insulating material 94" as a second insulating section, and an "insulating material 96" as a third insulating section are arranged between the outer wall material 48 and the inner wall material 64.

[0051] The insulation material 90 consists of glass wool 90A covered with a film material 90B. When viewed from the thickness direction of the interior wall material 64, it fits within the interior wall frame 66, and when viewed from the height direction of the building, it fills the interior wall frame 66, with a portion of it fitting within the exterior interior wall frame 68. The film material 90B of the insulation material 90 is fixed to the indoor side surface of the vertical battens 74 of the interior wall frame 66 by mounting members such as nails (not shown).

[0052] The insulation material 92 is composed of glass wool 92A covered with a film material 92B, and is located on the outdoor side of the insulation material 90, fits within the outer inner wall frame 68 when viewed from the thickness direction of the inner wall material 64, and is filled within the outer inner wall frame 68 when viewed from the height direction of the building. The film material 92B of the insulation material 92 is fixed to the outdoor side surface of the vertical battens 74 by mounting members such as nails (not shown). Furthermore, in the following, the assembly of insulation material 90 and insulation material 92 will be referred to as the "insulation section 98" as the first insulation section.

[0053] The insulation material 94 consists of glass wool 94A covered with a film material 94B. It is located on the outdoor side of the insulation material 92 and fits within the exterior wall frame 40 when viewed from the thickness direction of the interior wall material 64, and its main portion is located within the exterior wall frame 40 when viewed from the height direction of the building. The film material 94B of the insulation material 94 is fixed to the outdoor side surface of the vertical battens 80 of the outer interior wall frame 68 by mounting members such as nails (not shown).

[0054] The insulation material 96 is composed of glass wool 96A covered with a film material 96B, and is positioned along the indoor-side flange portion 42B of the vertical batten 42 of the adjacent exterior wall frame 40 when viewed from the thickness direction of the interior wall material 64. This insulation material 96 is joined to the indoor-side surface of the flange portion 42B by a joint (not shown) made of adhesive or the like, and is in a state of bulging inward from the flange portion 42B.

[0055] <Operation and Effects of This Embodiment> Next, the operation and effects of this embodiment will be described.

[0056] In this embodiment, as shown in Figure 1, the interior wall surface 60A of the building 10 is formed by the interior wall material 64. The interior wall frame 62 is configured in a rectangular frame shape, including an upper horizontal bar 62A, a lower horizontal bar 62B, and a pair of vertical bars 62C, which are arranged along the periphery of the interior wall material 64. The interior wall frame 62 is fixed to the ceiling 28 and the floor 34.

[0057] Furthermore, an exterior wall frame 40 is positioned on the exterior side of the interior wall frame 62. This exterior wall frame 40 is constructed in a rectangular frame shape, including an upper horizontal bar 44, a lower horizontal bar 46, and a pair of vertical bars 42 that overlap with the vertical bar 62C when viewed from the thickness direction of the interior wall material 64. The exterior wall frame 40 is fixed to the ceiling 28 and the floor 34.

[0058] Furthermore, in this embodiment, the insulation portion 98 is partially housed within the inner wall frame 62, and the insulation material 94 is partially housed within the outer wall frame 40 and located on the outdoor side of the insulation portion 98, thereby suppressing heat transfer between the outdoor and indoor sides.

[0059] Incidentally, a configuration in which there is no insulation between the vertical battens 62C of the interior wall frame 62 and the vertical battens 42 of the exterior wall frame 40 is undesirable from the standpoint of ensuring the thermal insulation performance of the building 10.

[0060] In this regard, for example, a configuration in which a board-shaped insulation material is placed between the vertical battens 62C and 42 can be considered, but if such a configuration is adopted, it becomes difficult to place wiring or the like between the vertical battens 62C and 42.

[0061] In this embodiment, as shown in Figure 3, an insulating material 96 is attached to the inner wall frame 62 side of the vertical battens 42 of the outer wall frame 40, and this insulating material 96 is made up of fibrous insulating material that has been packaged.

[0062] Therefore, in this embodiment, the space between the vertical battens 62C and 42 can be filled with the insulating material 96. Furthermore, when arranging wiring or the like between the vertical battens 62C and 42, the insulating material 96 can be deformed to secure space for arranging the wiring or the like.

[0063] Furthermore, in this embodiment, the inner wall frame 62 is composed of an inner inner wall frame 66 that constitutes the indoor side and an outer inner wall frame 68 that constitutes the outdoor side. In addition, the insulation section 98 is composed of an insulation material 90 that constitutes its indoor side and is mainly housed within the inner inner wall frame 66 and is made of fibrous insulation material that has been packaged, and an insulation material 92 that constitutes its outdoor side and is mainly housed within the outer inner wall frame 68 and is made of fibrous insulation material that has been packaged.

[0064] Therefore, in this embodiment, an insulating layer including an inner wall frame 66 and insulating material 90, and an insulating layer including an outer wall frame 68 and insulating material 92 are formed in the building 10, thereby ensuring the insulating performance of the building 10. Furthermore, by standardizing the inner wall frame 66 and insulating material 90 with those used in buildings with a single insulating layer, for example, the efficiency of parts management can be improved.

[0065] In addition, in this embodiment, the insulation material 94 is attached to the outdoor side surface of the outer inner wall frame 68, and the insulation material 94 and the insulation material 96 are brought into close contact, thereby improving the thermal insulation performance of the building 10.

[0066] As described above, in the thermal insulation structure of the building according to this embodiment, wiring and the like can be placed between the vertical battens 42 of the interior wall frame 62 and the vertical battens 42 of the exterior wall frame 40 while ensuring the thermal insulation performance of the building 10.

[0067] In the embodiment described above, the thicknesses of the insulation material 90, insulation material 92, and insulation material 94 in the thickness direction of the interior wall material 64 were set to be approximately the same, but this is not limited to this. For example, it is also possible to adopt a configuration in which the thickness of insulation material 92 is set to about twice the thickness without placing insulation material 94.
