DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [First embodiment] A first embodiment of the present invention will be described with reference to the drawings. 2 to 4, the wall 1 of the building shown in Fig. 1 comprises a skeleton 11, an inner wall 12 fixed to the indoor side of the skeleton 11 and made of, for example, gypsum board, and an outer wall 13 fixed to the outdoor side of the skeleton 11. The skeleton 11 comprises a plurality of vertical members (pillars) 111 arranged at equal intervals in the left-right direction.

[0010] Three insulating panels 2, each having a width dimension longer than the interval between a pair of vertical members 111 adjacent to each other in the left-right direction and a height dimension equal to the height dimension of the wall body 1, are attached to the inner wall 12 of the wall body 1 so as to be lined up at equal intervals in the width direction. A gap S as an exposed portion formed between a pair of adjacent insulating panels 2 is provided so as to face a portion of the inner wall 12 that abuts against the vertical members 111. The insulating panel 2 includes a deformable insulating material 21 and a decorative panel 22 attached to one surface of the insulating material 21, and is attached to the inner wall 12 via double-sided tape (not shown) provided on the other surface of the insulating material 21.

[0011] Fixture connecting members 3 are fixed in the two gaps S, respectively, for connecting and fixing shelf boards B as fixtures to the wall body 1. The fixture connecting members 3 include a trim material 31 and a bracket 32.

[0012] The trim material 31 is an elongated member formed of, for example, aluminum in a substantially channel shape, with a cross-sectional shape that is equal in the length direction and a length that is equal to the height dimension of the gap S, and includes a groove forming portion 311, a pair of locking protrusions 312, and a pair of legs 313. The groove forming portion 311 forms a groove portion 314 that is recessed toward the inner wall 12 side (outside the room), and includes a rectangular plate-shaped bottom surface portion 315 and a pair of side surface portions 316 that extend from both ends of the short side direction of the bottom surface portion 315 in a direction perpendicular to the bottom surface portion 315. A pair of edge cover portions 317 that respectively protrude in directions away from each other are provided at the extending ends of each side surface portion 316. The locking protrusions 312 are provided so as to protrude from the bottom surface portion 315 side of the extending ends of each side surface portion 316 in a direction approaching each other. The legs 313 are provided so as to extend from both ends of the short side direction of the bottom surface portion 315 in a direction opposite to each side surface portion 316. The trim material 31 is fixed to the vertical member 111 by a plurality of body-side screws 33 that penetrate the bottom portion 315 and the inner wall 12, so that the legs 313 abut against the inner wall 12, each side portion 316 abuts against the small edge of each insulation panel 2, and each edge covering portion 317 covers the edge of each insulation panel 2.

[0013] The bracket 32 ​​is formed in a generally L-shape from aluminum, for example, and includes a body-side fixing part 321 and a fixture-side fixing part 322 perpendicular to the body-side fixing part 321. The width dimensions of the body-side fixing part 321 and the fixture-side fixing part 322 are shorter than the dimension between the tips of the pair of locking projections 312. The bracket 32 ​​is fixed to the vertical member 111 by a plurality of body-side screws 34 serving as body-side fixing devices that penetrate the bottom part 315 and the inner wall 12, so that the fixture-side fixing part 322 protrudes from the inner wall 12 to the room side with the body-side fixing part 321 positioned within the groove part 314. A shelf board B is fixed to the upper surface of the fixture-side fixing portion 322 of each bracket 32 ​​by a plurality of fixture-side screws 35.

[0014] A cover material 36 that covers the groove portion 314 is detachably attached to the upper and lower portions of the fixture-side fixing portion 322 of the trim material 31. The cover material 36 is, for example, a long member formed of the same material as the trim material 31 and having a cross-sectional shape equal in the length direction. The cover material 36 includes a rectangular plate-shaped cover body 361 whose width dimension is approximately equal to the dimension between the pair of side portions 316, and a pair of locking pieces 362 that extend from both ends of the short side direction of the cover body 361 in a direction perpendicular to the cover body 361. The cover material 36 is attached so that each locking piece 362 is locked to the locking protrusion 312 of the trim material 31, and the indoor surface of the cover body 361 is positioned approximately on the same plane as the indoor surface of the edge covering portion 317 of the trim material 31. The upper cover material 36 is provided from the upper end of the trim material 31 to a position above the upper surface of the fixture side fixing part 322, and the lower cover material 36 is provided from a position below the lower surface of the fixture side fixing part 322 to the lower end of the trim material 31.

[0015] Next, a method for insulating and renovating the wall 1 will be described. First, the three insulating panels 2 are attached to the inner wall 12 so as to form gaps S as exposed portions. By attaching the insulating panels 2 in this manner, it is not necessary to perform notching or drilling on the insulating panels 2 to form the exposed portions, which facilitates installation. Next, the parting materials 31 positioned in each gap S are fixed to the vertical members 111. By providing the parting materials 31 in this manner, it is possible to prevent the inner wall 12 from being exposed, and the design of the wall body 1 is improved. Thereafter, the bracket 32 ​​is fixed to the vertical member 111 with the frame-side fixing portion 321 positioned within the groove 314. Fixing the bracket 32 ​​in this manner prevents the frame-side fixing portion 321 and the frame-side screws 34 from protruding from the inner wall 12 toward the room side. Also, by adjusting the mounting height of the bracket 32, the shelf board B can be fixed at a desired height position. Finally, the cover material 36 is attached to the portion of the trim material 31 where the fixture-side fixing portion 322 does not protrude. By attaching the cover material 36 in this manner, the design of the wall body 1 is improved and the accumulation of dust and the like in the groove portion 314 can be suppressed. After the work based on the above-mentioned insulation renovation method has been completed, the shelf board B is fixed to the fixture-side fixing part 322 using the fixture-side screws 35.

[0016] According to the above-described heat-insulating structure of the wall 1 of the first embodiment, in the gap S exposing the inner wall 12, the fixture connecting member 3 is fixed to the vertical member 111 by the frame-side screw 34 penetrating the fixture connecting member 3 and the inner wall 12. In this way, the fixture connecting member 3 can be firmly fixed by fixing the fixture connecting member 3 to the vertical member 111 without penetrating the frame-side screw 34 into the insulation panel 2 including the deformable insulation material 21. Therefore, the fixing strength of the shelf board B fixed to the vertical member 111 via such a fixture connecting member 3 can be ensured. Furthermore, by attaching the insulation panel 2 to the inner wall 12, the insulation performance can be improved.

[0017] [Second embodiment] Next, a second embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the first embodiment are given the same reference numerals and names, and the description will be simplified or omitted. As shown in Fig. 6, the wall 1A of the building shown in Fig. 5 includes a skeleton 11, an inner wall 12, and an outer wall 13. The skeleton 11 includes a plurality of horizontal members (furring strips) 112 arranged at equal intervals in the vertical direction.

[0018] Three insulation panels 2, each having a height dimension longer than the distance between a pair of vertically adjacent horizontal members 112 and a width dimension equal to the width dimension of the wall body 1, are attached to the inner wall 12 of the wall body 1A so as to be lined up at equal intervals in the height direction. An upper gap S1 is formed as an exposed portion between the first insulation panel 2 and the second insulation panel 2 from the top, and a lower gap S2 is formed as an exposed portion between the second insulation panel 2 and the third insulation panel 2 from the top. The upper gap S1 and the lower gap S2 are provided so as to face the portion of the inner wall 12 that abuts against the horizontal members 112.

[0019] In the upper gap S1, a parting material 31 is fixed to the horizontal member 112 by a plurality of screws 37 penetrating the bottom surface portion 315 and the inner wall 12. A cover material 36 is removably attached to the parting material 31.

[0020] A fixture connecting member 4 for connecting and fixing the shelf board B to the wall body 1A is fixed in the center of the lower gap S2. The fixture connecting member 4 is a long member made of aluminum, for example, and has a uniform cross-sectional shape in the length direction. The fixture connecting member 4 has a rectangular plate-shaped connecting base 41. An upper side portion 42 extending in a direction perpendicular to the connecting base 41 is provided at one end of the short side of the connecting base 41. An intermediate plate portion 43 extending parallel to the upper side portion 42 is provided at the center of the short side of the connecting base 41. The extension dimension of the intermediate plate portion 43 is longer than the extension dimension of the upper side portion 42. At the extension tip of the upper side portion 42, an end edge cover portion 44 protruding in a direction away from the intermediate plate portion 43 and a fixture holding protrusion 45 protruding in a direction toward the intermediate plate portion 43 are provided. The dimension from the tip of the fixture holding protrusion 45 to the intermediate plate portion 43 is approximately equal to the thickness dimension of the shelf board B. An edge cover portion 46 that protrudes in a direction away from the upper side surface portion 42 is provided at a position on the intermediate plate portion 43 corresponding to the edge cover portion 44 .

[0021] The fixture connecting member 4 having the above-mentioned configuration has a parting portion 47, a fixture-side fixing portion 48, and a fixing piece 49 as functional components. The parting portion 47 is composed of a bottom surface portion 50 that connects the upper side surface portion 42 and the intermediate plate portion 43 in the connecting base portion 41, the upper side surface portion 42, a portion of the intermediate plate portion 43 that is closer to the base end than the edge covering portion 46, the edge covering portion 44, and the edge covering portion 46, and forms a groove portion 51 that is recessed toward the inner wall 12. The groove portion 51 has a height dimension that allows the end of the shelf board B to be inserted. The fixture-side fixing portion 48 is composed of a portion of the intermediate plate portion 43 that is closer to the tip end than the edge covering portion 46. The fixing piece 49 is composed of a portion of the intermediate plate portion 43 other than the bottom surface portion 50. The fixture connecting member 4 is fixed to the cross member 112 by the fixing piece 49 or bottom portion 50, and by a plurality of body-side screws 52 which penetrate the inner wall 12 and serve as body-side fixing devices, so that the connecting base 41 abuts the inner wall 12, the upper surface portion 42 and the portion constituting the parting portion 47 at the intermediate plate portion 43 abut the small edges of each insulation panel 2, the edge covering portions 44, 46 cover the edges of each insulation panel 2, and the fixing piece 49 is covered by the insulation panel 2. A shelf board B is fixed to the upper surface of a fixture-side fixing part 48 provided so as to protrude from the inner wall 12 toward the room side by a plurality of fixture-side screws 53.

[0022] On both the left and right sides of the fixture connecting member 4 in the lower gap S2, a pair of trim members 31 are fixed to the cross member 112 by a plurality of screws (not shown) that penetrate the bottom portion 315 and the inner wall 12. The left-right dimension of the right-side trim member 31 is equal to the dimension from the right end of the insulation panel 2 to the right end of the fixture connecting member 4, and the left-side dimension of the left-side trim member 31 is equal to the dimension from the left end of the insulation panel 2 to the left end of the fixture connecting member 4. A cover material 36 is removably attached to each trim member 31.

[0023] Next, a method for insulating and renovating the wall body 1A will be described. First, the first and second insulation panels 2 from the top are attached to the inner wall 12 so as to form an upper gap S1. Next, the trim material 31 located in the upper gap S1 is fixed to the horizontal member 112. Thereafter, the fixture connecting member 4 is fixed to the horizontal member 112 so as to abut against the lower edge of the second insulation panel 2 from the top. Next, the third insulation panel 2 from the top is attached to the inner wall 12 so as to form a lower gap S2. Then, a pair of trim materials 31 located on both the left and right sides of the fixture connecting member 4 in the lower gap S2 are fixed to the horizontal member 112. Finally, cover materials 36 are attached to each trim material 31. The work of attaching the covering material 36 to the trim material 31 in the upper gap S1 may be performed immediately after the work of fixing the trim material 31. Moreover, the work of fixing the trim materials 31 on both the left and right sides of the fixture connecting member 4 may be performed immediately after or immediately before the work of fixing the fixture connecting member 4. After the work based on the insulation renovation method described above has been completed, shelf board B is fixed to fixture-side fixing part 48. When fixing shelf board B, first, the end of shelf board B is inserted into groove part 51. In this state, shelf board B is placed on fixture-side fixing part 48 and held by fixture-holding protrusion 45 and intermediate plate part 43. This prevents shelf board B from falling even if hands are released from shelf board B. Finally, shelf board B is fixed to fixture-side fixing part 48 using fixture-side screws 53.

[0024] According to the thermal insulation structure of the wall body 1A of the second embodiment as described above, in the lower gap S2, the fixture connecting member 4 is fixed to the horizontal member 112 by the frame-side screws 52 that penetrate the fixture connecting member 4 and the inner wall 12. Therefore, similar to the first embodiment, the fixing strength of the shelf board B fixed to the horizontal member 112 via the fixture connecting member 4 can be ensured and the thermal insulation performance can be improved. In addition, since the fixture connecting member 4 functions as a trim portion 47 and a fixture side fixing portion 48, the number of parts can be reduced compared to the configuration of the first embodiment which uses the trim material 31 and the bracket 32, making construction easier.

[0025] [Third embodiment] Next, a third embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the second embodiment are given the same reference numerals and names, and the description will be simplified or omitted. As shown in Fig. 8 and Fig. 9, the wall 1B of the building shown in Fig. 7 includes a skeleton 11B having an opening 10B, an inner wall 12, and an outer wall 13. The skeleton 11B includes an opening frame 113B composed of two vertical members 111B and two horizontal members 112B. Spacers 114B are attached to the opposing surfaces of the opening frame 113B. The opening frame 113B and the spacer 114B form an opening 10B. An outer window 6 and a frame 7 are attached to the opening 10B.

[0026] The exterior window 6 comprises an exterior window frame 61 and a pair of shoji screens 62 supported by the exterior window frame 61. The exterior window frame 61 is constructed by framing an upper frame, a lower frame, and left and right vertical frames, each of which is made of an aluminum extrusion, and is screwed to the spacer 114B and the opening frame 113B at different positions. The pair of shoji screens 62 are constructed by assembling an upper frame, a lower frame, left and right vertical frames, and a single-pane glass panel (face material), each of which is made of an aluminum extrusion. The exterior window 6 is a sliding window in which the pair of shoji screens 62 are supported inside the exterior window frame 61 in a left-right sliding manner so that they can be opened and closed. The frame 7 comprises an upper frame material 71, a lower frame material 72 and left and right vertical frame materials 73, and is screwed to the outer window frame 61 so as to protrude from the inner wall 12 toward the inside of the room.

[0027] One upper insulation panel 2B1, one lower insulation panel 2B2, and two middle insulation panels 2B3 are attached to the inner wall 12 of the wall body 1B. The upper insulation panel 2B1 has a height dimension longer than the dimension from the upper end of the wall body 1B to the upper horizontal member 112B, and a width dimension equal to the width dimension of the wall body 1B. The lower insulation panel 2B2 has a height dimension longer than the dimension from the lower end of the wall body 1B to the lower horizontal member 112B, and a width dimension equal to the width dimension of the wall body 1B. The height dimension of each middle insulation panel 2B3 is shorter than the interval between the vertically adjacent vertical members 111B, and a width dimension longer than the dimension from the side end of the wall body 1B to the horizontal member 112B. Each middle insulation panel 2B3 is attached so that a gap is formed between each vertical frame member 73. The upper insulation panel 2B1 is attached to the upper frame material 71 or each of the middle insulation panels 2B3 so that an upper gap S11 is formed as an exposed portion between the upper frame material 71 or each of the middle insulation panels 2B3. The lower insulation panel 2B2 is attached to the lower frame material 72 or each of the middle insulation panels 2B3 so that a lower gap S12 is formed as an exposed portion between the lower frame material 72 or each of the middle insulation panels 2B3. Each of the insulation panels 2B1, 2B2, and 2B3 includes a deformable insulation material 21 and a decorative panel 22 attached to one side of the insulation material 21, and is attached to the inner wall 12 via a double-sided tape (not shown) provided on the other side of the insulation material 21.

[0028] The fixture connecting member 4 is fixed in the center of the upper gap S11 with the intermediate plate portion 43 positioned above the upper side surface portion 42. The fixture connecting member 4 is fixed in the center of the lower gap S12 with the upper side surface portion 42 positioned above the intermediate plate portion 43. Each fixture connecting member 4 is fixed to the cross member 112B by a fixing piece 49 or a bottom surface portion 50, and by a plurality of frame-side screws 52 that penetrate the inner wall 12, as in the second embodiment. A shelf board B as a plate-shaped member is fixed to the underside of the fixture side fixing part 48 of the fixture connecting member 4 in the upper gap S11 and to the upper surface of the fixture side fixing part 48 of the fixture connecting member 4 in the lower gap S12 by a plurality of fixture side screws 53.

[0029] As in the second embodiment, on both the left and right sides of the fixture connecting member 4 in the upper gap S11 and the lower gap S12, a pair of trim members 31 are fixed to the cross members 112 by a plurality of screws (not shown) that penetrate the bottom surface portion 315 and the inner wall 12. A cover material 36 is removably attached to each trim member 31.

[0030] Between the upper and lower shelf boards B, an inner window 8 whose width dimension is shorter than that of each shelf board B is attached so as to be positioned at the center in the width direction of each shelf board B. The inner window 8 comprises an inner window frame 81 fixed to the upper and lower shelf boards B, and a pair of shoji screens 82 supported by the inner window frame 81. The inner window frame 81 has an upper frame 83, a lower frame 84, and left and right vertical frames 85, and the pair of shoji screens 82 are each constructed by assembling an upper frame, a lower frame, left and right vertical frames, and a single-pane glass panel (surface material). The upper frame 83 has a pair of upper rail portions 831 that fit into grooves at the upper ends of the pair of shoji screens 82. The lower frame 84 has a pair of lower rail portions 841 that fit into grooves at the lower ends of the pair of shoji screens 82. The upper frame 83 and the lower frame 84 are screwed to the upper and lower shelf boards B, respectively, and the left and right vertical frames 85 are screwed to the left and right vertical frame materials 73, respectively, with their outer peripheries abutting the small edges of the respective middle insulation panels 2B3. The inner window 8, like the outer window 6, is a sliding window (plastic window) in which a pair of shoji screens 82 are supported inside an inner window frame 81 so that they can be slid open and closed in a left-right sliding manner.

[0031] Next, a method for insulating and renovating the wall body 1B will be described. First, the insulation panels 2B1, 2B2, 2B3 are attached to the inner wall 12 of the wall body 1B in which the exterior window 6 and the frame 7 are provided, so as to form an upper gap S11 and a lower gap S12. Next, the upper fixture connecting member 4 is fixed to the horizontal member 112 so as to abut against the lower edge of the upper insulation panel 2B1, and the lower fixture connecting member 4 is fixed to the horizontal member 112 so as to abut against the upper edge of the lower insulation panel 2B2. Then, a pair of trim members 31 positioned on both the left and right sides of the fixture connecting member 4 in the upper gap S11 and the lower gap S12 are fixed to the horizontal member 112. Finally, a cover member 36 is attached to each trim member 31. After the work based on the insulation renovation method described above, each shelf board B is fixed to each fixture-side fixing part 48 in the same manner as in the second embodiment. Next, each shelf board B is fixed to each fixture-side fixing part 48 using the fixture-side screws 53. Then, the inner window 8 is screwed to each shelf board B and each vertical frame material 73 of the frame 7. The spaces on the top surface of the upper shelf board B to which the inner window 8 is fixed and on the underside of the lower shelf board B where the inner window 8 is not located in this way can be used as space for placing various items.

[0032] According to the heat-insulating structure of the wall 1B of the third embodiment as described above, like the second embodiment, the fixing strength of each shelf board B fixed to the horizontal member 112 via the fixture connecting member 4 can be ensured, and the fixing strength of the inner window 8 fixed to each shelf board B can also be ensured, while improving the heat-insulating performance. Furthermore, even if the protruding dimension of the frame 7 from the inner wall 12 is short, the inner window 8 can be firmly attached.

[0033] [Variations] In the first embodiment, multiple insulation panels with notches or holes that function as exposure portions may be attached to the entire inner wall 12 so that they are in contact with each other, or a single insulation panel with notches or holes may be attached and a fixture connecting member 3 may be attached to the notch or hole, and a similar configuration may be applied to the second and third embodiments. In the first embodiment, the parting material 31 may be formed in a rod shape without the groove portion 314, and the bracket 32 ​​may be fixed to the indoor surface of the rod-shaped portion, in which case the cover material 36 will not be necessary. In the second and third embodiments, the portion corresponding to the parting portion 47 in the fixture connecting member 4 may be formed into a rod shape without a groove portion 51, and the shelf board B may be fixed so that the end face of the shelf board B abuts against the indoor side surface of the rod-shaped portion.

[0034] In the first to third embodiments, the cover material 36 does not need to be attached to the parting material 31 . In the second and third embodiments, a fixture connecting member 4 is attached to the center of each gap S2, S11, S12 and a trim material 31 is attached to both the left and right sides, but it is also possible to attach a fixture connecting member 4 of the same width as each gap S2, S11, S12 without attaching the trim material 31, and cut out the portion of the fixture connecting member 4 that corresponds to the fixture side fixing part 48 that is not in contact with the shelf board B, and attach a cover material 36 to the cut-out part. Although the frame-side screws 33, 34, and 52 have been exemplified as frame-side fixing devices of the present invention, nails may also be used. Although a shelf board B and an interior window 8 have been given as examples of fixtures that can be fixed to a wall by the fixture connecting member of the present invention, the present invention is not limited to these and may also include storage shelves for various items such as books and tableware, chests of drawers, air conditioners, televisions, etc.

[0035] [Summary of the invention] The insulating structure of a wall of the present invention is characterized in that an inner wall is fixed to a main body, an insulating panel is attached to the inner wall so as to provide an exposed portion that exposes the inner wall, and a fixture connecting member for connecting and fixing a fixture to the wall body is fixed to the exposed portion by the fixture connecting member and a main body side fixing device that penetrates the inner wall. According to the present invention, since the fixture on the building structure side does not penetrate the insulation panel, the fixture connecting member can be firmly fixed to the building structure. Therefore, the fixing strength of the fixture fixed via such a fixture connecting member can be ensured. Furthermore, by attaching the insulation panel to the inner wall, the insulation performance can be improved.

[0036] In the wall insulation structure of the present invention, it is preferable that the exposed portion is a gap formed between a pair of the insulation panels.
