Description

[Technical field]

[0001] The present invention relates to a frame mounting structure for mounting a frame of a fitting to an opening frame of a building structure, and to a wall unit. [Background technology]

[0002] As shown in Patent Documents 1 and 2, when attaching a fitting frame to a building frame opening, the two are fixed with screws to ensure strength. For example, in the mounting structure described in Patent Document 1, as shown in Fig. 16, the gap between the building frame opening frame 500 and the fitting frame 502 is filled with spacers 504 and packing material 506, and further airtightness and waterproofness are ensured by attaching a waterproof sheet 508. In addition, the building frame opening frame 500 and the frame 502 are fixed with screws 510. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP2021-050504 Public Relations [Patent Document 2] JP 2019-65503 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, a considerable number of screws are required to ensure sufficient fixing strength between the frame of the opening in the building structure and the frame of the fitting, and the screw fixing work takes time. In addition, the airtight and waterproof structure is formed by spacers, packing materials, and waterproof sheets, and there are many parts, and there is a concern that gaps will occur between each component. Furthermore, if the waterproof sheet is attached by an inexperienced worker, it may wrinkle and cause discontinuities, which may reduce the airtightness and waterproofness.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a frame mounting structure and wall unit that reduces or eliminates the number of screws and other parts used for fixing when attaching a building frame to a structural opening frame, and that also provides sufficient airtightness and waterproofing. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the objective, the frame body mounting structure of the present invention is a frame body mounting structure for mounting a frame body of a fitting to a structural opening frame, and is characterized in that the indoor side boundary, which is the indoor side edge of the opposing surfaces between the structural opening frame and the frame body, is continuously sealed around all four sides with adhesive.

[0007] Furthermore, the frame body mounting structure of the present invention is a frame body mounting structure for mounting a frame body of a fitting to a structural opening frame, and is characterized in that at least one of the areas between the opposing surfaces of the structural opening frame and the frame body and the exterior boundary which is the exterior edge of the opposing surfaces is continuously sealed with adhesive between the upper frame of the frame body and the upper material of the structural opening frame, and between the vertical frame of the frame body and the vertical material of the structural opening frame.

[0008] Furthermore, the wall unit of the present invention is characterized in that the frame opening frame and the frame body are unitized by applying the described frame body mounting structure, and the wall unit is attached to the building structure via the frame opening frame. Effect of the Invention

[0009] According to the present invention, when attaching the frame of the fitting to the frame of the opening of the building frame, the boundary on the interior side is sealed and bonded / fixed continuously around the four sides by adhesive, or the opposing surfaces are bonded and fixed to each other, so that an appropriate fixing strength can be obtained. Therefore, the screws for fixing the frame of the opening of the building frame to the frame can be omitted or the number of screws can be reduced, and the fixing process can be shortened. In addition, the adhesive serves as both a fixing means and an airtight / waterproofing means, so that the number of screws can be reduced and spacers and packing materials used in the conventional technology can be omitted, and the number of parts can be reduced. Furthermore, by fixing the four sides continuously with adhesive, there are no discontinuous parts, and wrinkles like those of waterproof tape do not occur, so sufficient airtightness and waterproofness can be obtained. In addition, even if adhesive is provided only on the exterior side, sufficient airtightness and waterproof performance can be obtained depending on the conditions.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the frame mounting structure and wall unit according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these preferred embodiments.

[0012] Fig. 1 is a schematic front view of a wall unit 10 according to an embodiment of the present invention, as viewed from the indoor side. Fig. 2 is a vertical cross-sectional view of the wall unit 10. Fig. 3 is a horizontal cross-sectional view of the wall unit 10.

[0013] The wall unit 10 is handled as a single structure when attached to a building, and includes a fitting 14 and a structural opening frame 16. The fitting 14 and the structural opening frame 16 are joined by a mounting structure 12 which is an embodiment of the present invention. In other words, the wall unit 10 is a unit formed by applying the mounting structure 12 to the structural opening frame 16 and the frame body 18. The wall unit 10 is attached to the structural body of a building 50 (see FIG. 5) via the structural opening frame 16.

[0014] The fitting 14 is a shoji screen 20 supported inside a frame 18. The frame 18 is formed by framing an upper frame 22, a lower frame 24, and left and right vertical frames 26 on all four sides. The frame 18 is arranged on the inner periphery of the frame 16 of the frame body opening without any gaps. In other words, the frame 18 is sized to fit into the frame 16 of the frame body opening, and there is almost no gap between them. However, a narrow gap may be provided so that the frame 18 can be easily fitted into the frame 16 of the frame body opening, but the gap width is set to a level that can be filled with adhesives 60a and 60b described later. In other words, in this application, it is sufficient that there is no substantial gap between the frame 18 and the frame 16 of the frame body opening. Of course, the gap may be zero. It is sufficient that there is no substantial gap between the frame 18 and the frame 16 of the frame body opening, not over the entire visible surface, but only in a part of the visible direction. The structure between the frame body 18 and the frame opening frame 16 is not limited to a fitting structure as long as there is no substantial gap between them.

[0015] Frame materials having the same cross-sectional shape are used as the upper frame 22, the lower frame 24, and the left and right vertical frames 26. The frame materials constituting the upper frame 22, the lower frame 24, and the left and right vertical frames 26 are extruded shapes formed from metal such as aluminum alloy, or resin. When resin is used for these frame materials, metal reinforcing materials may be provided as appropriate.

[0016] In this application, the front direction refers to the indoor / outdoor direction of the fitting 14. The front surface refers to a surface that extends along the front direction. The front direction is a direction perpendicular to the front direction, and in the case of a vertical frame 26 that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction, and in the case of an upper frame 22 that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction. The front surface refers to a surface along the front direction. In each figure, the left-right direction is indicated by arrow X, the up-down direction by arrow Y, and the front direction by arrow Z, as appropriate.

[0017] The shoji screen 20 is made up of a rectangular panel 28 to which an upper frame 30, a lower frame 32, and left and right vertical frames 34 are attached on all four sides, and is configured to be large enough that all four facing surfaces facing the outside can simultaneously abut against the door stop of the frame 18. In this embodiment, a link mechanism 29 is provided between the vertical frames 34 and the vertical frame 26, and the shoji screen 20 forms a sliding window that opens toward the inside of the room.

[0018] In this embodiment, the upper frame 30, lower frame 32, and left and right vertical frames 34 that make up the shoji screen 20 are made of frame material having the same cross-sectional shape as the frame body 18. The face material 28 is, for example, composite glass. The inside of the frame body 18 in the fitting 14 is not limited to a sliding window type shoji screen 20, but may also be a sliding door type shoji screen, a door, or a revolving window. The gap between each frame of the shoji screen 20 and the frame body 18 is sealed with a plurality of sealants 33.

[0019] The structural opening frame 16 is a rectangular frame formed by providing a lintel (upper material) 36 and a window sill (lower material) 38 above and below between the left and right vertical members 35. The lintel 36 corresponds to the upper material of the structural opening frame 16, and the window sill 38 corresponds to the lower material of the structural opening frame 16.

[0020] In the frame 16, horizontal members 40 (see FIG. 1) are provided in the areas above the lintel 36 and below the window sill 38. The horizontal members 40 are provided between the vertical members 35 with gaps between the lintel 36 and the window sill 38. Heat insulating materials 42 are provided in the gaps between the lintel 36 and the horizontal members 40 and between the window sill 38 and the horizontal members 40. The lintel 36, window sill 38, vertical members 35, and horizontal members 40 are structural members, and are made of wood, for example. The surface member 44 is a flat member made of plywood, and is fixed to the exterior facing surfaces of the lintel 36, window sill 38, and upper and lower horizontal members 36, and to the exterior facing surfaces of the left and right vertical members 35. The surface material 44 in this embodiment forms the visible surface of the lintel 36, the window sill 38, and the vertical member 35, facing the outside of the room. An opening 44a is formed in the center of the surface material 44 to expose the fitting 14.

[0021] The visible surfaces of the lintel 36, window sill 38 and vertical member 35, i.e., the surface of the facing material 44, are on the same plane as the visible surfaces of the upper frame 22, lower frame 24 and vertical frame 26 of the frame body 18. The lintel 36, window sill 38 and vertical member 35 have larger dimensions in the visible direction than the upper frame 22, lower frame 24 and vertical frame 26, and protrude slightly into the room.

[0022] Next, we will explain the mounting structure 12 that mounts the frame 18 of the fitting 14 to the building frame opening frame 16. The mounting structure 12 includes an adhesive 60a on the indoor side, an adhesive 60b on the outdoor side, a waterproof sheet 62 on the outdoor side, and the like.

[0023] As described above, since there is no substantial gap between the frame 16 and the frame 18, the frame 16 and the frame 18 are substantially in contact with each other. In the present application, the interior edge of the opposing faces 80, 80 of the frame 16 and the frame 18 (when there are multiple pairs of opposing faces, the pair closest to the interior) is the interior boundary 66. In other words, the interior boundary 66 is the boundary of the parts of the frame 16 and the frame 18 that are exposed to the interior. Specifically, in this embodiment, the boundary between the inner peripheral face 36a of the lintel 36 and the interior facing face 22a of the upper frame 22, the boundary between the inner peripheral face 38a of the window sill 38 and the interior facing face 24a of the lower frame 24, and the boundary between the inner peripheral face 35a of the vertical member 35 and the interior facing face 26a of the vertical frame 26 form the interior boundary 66. The adhesive 60a is applied across the two surfaces that form the interior boundary 66, and the two surfaces are bonded together. The facing surfaces 80, 80 between the frame 16 and the frame 18 are the locations where the inner peripheral side facing surface of the frame 16 and the outer peripheral side facing surface of the frame 18 overlap along the facing direction. Since there is substantially no gap between the frame 16 and the frame 18, the facing surfaces 80, 80 between the frame 16 and the frame 18 are mutually covered. If there is no gap at all between the frame 16 and the frame 18, the facing surfaces 80, 80 between the frame 16 and the frame 18 are abutting surfaces.

[0024] The adhesive 60a on the indoor side seals the indoor side boundary 66 between the structural body opening frame 16 and the frame body 18 continuously around all four sides, fixing the structural body opening frame 16 to the frame body 18. Since the adhesive 60a fixes the structural body opening frame 16 to the frame body 18 continuously around all four sides without any gaps, airtightness and watertightness are guaranteed and the fixing strength is quite strong.

[0025] In this application, the outside edge of the facing surfaces 82, 82 (when there are multiple pairs of facing surfaces, the pair on the outermost side of the room is used. Here, a different reference number is used to distinguish them from the above-mentioned facing surfaces 80, 80) between the frame 16 for the opening of the structural body and the frame body 18 is the outside boundary 68. In other words, the outside boundary 68 is the boundary of the parts of the frame 16 for the opening of the structural body and the frame body 18 that are exposed to the outside of the room. The adhesive 60b on the outside of the room seals three of the four peripheries of the outside boundary 68 between the frame 16 for the opening of the structural body and the frame body 18, and fixes the frame 16 for the opening of the structural body and the frame body 18. Specifically, in this embodiment, the adhesive 60b seals the boundary between the outside facing surface 36b of the lintel 36 and the outside facing surface 22b of the upper frame 22, and the boundary between the outside facing surface 35b of the vertical member 35 and the outside facing surface 26b of the vertical frame 26. That is, the adhesive 60b is provided across the two surfaces that form the outdoor boundary 68, and the two surfaces are bonded together.

[0026] The adhesive 60b on the exterior side is continuously provided between the upper frame 22 of the frame body 18 and the lintel 36 of the frame body opening frame 16, and between the vertical frame 26 of the frame body 18 and the vertical member 35 of the frame body opening frame 16, in the exterior boundary 68. In this embodiment, the adhesive 60b is not provided between the lower frame 24 of the frame body 18 and the window sill 38 of the frame body opening frame 16. The adhesive 60b is provided on three sides between the frame body 18 and the frame body opening frame 16, which further improves airtightness, watertightness, and fixing strength. For example, hot melt type, two-liquid mixture type, moisture curing type, etc. can be applied as the adhesives 60a and 60b. The adhesive 60a on the interior side may be of a different type depending on the application location. Similarly, the adhesive 60b on the interior side may be of a different type depending on the application location.

[0027] Fig. 4 is an enlarged vertical cross-sectional view of the lower portion of the wall unit 10. As shown in Fig. 4, a waterproof sheet 62 is attached to the window sill 38 of the structural opening frame 16, covering the inner peripheral visible surface 38a and the outdoor visible surface 38b. A water cutout 65 is formed on the upper outdoor portion of the window sill 38. The waterproof sheet 62 is attached between the inner peripheral visible surface 38a and the outdoor visible surface 38b, via the inner peripheral visible surface 65a and the outdoor visible surface 65b of the water cutout 65. The waterproof sheet 62 is a thin film member that is waterproof and flexible.

[0028] The waterproof sheet 62 is not applied to the entire inner peripheral visible surface 38a, but only to the surface that is covered by the sill 24 and to an extent that it does not overlap with the adhesive 60a, and is not applied to the surface exposed to the interior. The adhesive 60a does not overlap with the waterproof sheet 62, reliably bonding the sill 24 and the window sill 38. The adhesive 60a and the waterproof sheet 62 may overlap by a small amount.

[0029] Rainwater that hits the surface material 28 of the shoji screen 20 will run down onto the window sill 38, but waterproofing is ensured by applying a waterproof sheet 62. In the mounting structure 12, the frame 16 and the frame body 18 are fixed to each other with adhesives 60a, 60b, and may be further fixed using a small number of screws as necessary. However, between the window sill 38, through which water may run down from above, and the lower frame 24, it is preferable not to install screws and not to drill screw holes in the waterproof sheet 62 to prevent water from entering through the screw holes.

[0030] Although no adhesive 60b is provided between the bottom frame 24 of the frame body 18 and the window sill 38 of the structural opening frame 16, the window sill 38 is waterproofed with a waterproof sheet 62 and has a water drain 65, so water rarely gets in between the bottom frame 24 and the window sill 38. Even if water does get in between the bottom frame 24 and the window sill 38, the adhesive 60a ensures waterproofing on the indoor side.

[0031] In addition, waterproof sheets 62 are attached to the three sides of the wall unit 10, the left and right sides and the top, which are fixed with the adhesive 60b, so as to cover the adhesive 60b, ensuring an additional layer of waterproofing. Depending on the design and construction conditions, the waterproof sheets 62 may be omitted from the areas that cover the adhesive 60b.

[0032] A recess 70 is formed in the lower frame 24 along the longitudinal direction. A support piece 72 is provided between the window sill 38 and the recess 70. The support piece 72 fits into the recess 70 and abuts against the outer peripheral visible surface of the lower frame 24, thereby supporting the fitting 14 from below. The recess 70 in the lower frame 24 is formed to allow for commonality with a frame body (see FIG. 16) in a conventional mounting structure. Therefore, if commonality with the conventional structure is not required, the recess 70 and support piece 72 may be omitted, and a large area may be secured for the outer peripheral visible surface of the lower frame 24 so that it comes into direct contact with the window sill 38.

[0033] FIG. 5 is a diagram for explaining a construction method for attaching the wall unit 10 to a building 50 to which the wall unit 10 is to be attached. To attach the wall unit 10 to a building 50 such as a house, as shown in FIG. 5, the wall unit 10 is placed between a frame 52 such as pillars and beams provided in the building 50, and fixed to the frame 52 via the horizontal members 40 and vertical members 35 of the frame opening frame 16. In such a construction method, the wall unit 10 may be manufactured in advance in a place with well-equipped facilities and environment such as a factory, and then transported to the construction site and attached to the frame 52. When the wall unit 10 is manufactured in a factory, the adhesives 60a and 60b may be applied along the indoor boundary 66 and the outdoor boundary 68 by automatically discharging the adhesives 60a and 60b from a nozzle provided on the hand of a robot, for example.

[0034] According to this construction method, even if the on-site worker does not have high skills, it is possible to accurately attach the wall unit 10 with high dimensional accuracy to the building, and it is possible to obtain high dimensional accuracy for the building provided with the wall unit 10. However, depending on the construction conditions, the work of attaching the frame 18 to the opening of the building frame 52 of the building 50 using adhesives 60a, 60b, etc. may be performed at the construction site. In this case, the fitting 14 does not need to be a unit with the frame 18 for the opening of the building frame.

[0035] According to the above-mentioned wall unit 10 and mounting structure 12, when mounting the frame body 18 of the fitting 14 to the frame of the opening 16 of the building frame, the frame body 18 is bonded and fixed by the adhesive 60a continuously around the four sides so as to close the interior boundary 66, and an appropriate fixing strength is obtained. Therefore, the screws for fixing can be omitted or the number of screws can be reduced, and the fixing process can be shortened. In the mounting structure 12, the adhesives 60a and 60b serve as both a fixing means and an airtight / waterproofing means, and the number of screws can be reduced, and the spacer 504 and the packing material 506 of the conventional technology (see FIG. 16) can be omitted, and the number of parts can be reduced. Conceptually, the adhesives 60a and 60b of the mounting structure 12 have the effect of consolidating the screws, spacers, and packing materials of the conventional technology.

[0036] More specifically, in the mounting structure 12, the adhesives 60a, 60b have airtight and waterproof properties, eliminating the need for packing materials. In addition, because packing materials are no longer necessary and because it is necessary to provide the adhesives 60a, 60b, there is almost no gap between the frame 16 for the opening in the main body and the frame 18. In addition, because there is almost no gap between the frame 16 for the opening in the main body and the frame 18, there is also no need for spacers for adjusting dimensions.

[0037] In addition, by fixing the four sides of the structure with adhesive 60a so as to close the interior boundary 66, there are no discontinuous parts and wrinkles, as occurs with waterproof tape, are not generated, so sufficient airtightness and waterproofing can be obtained. However, as described above, the mounting structure 12 may also use a waterproof sheet 62 on a part of the exterior side, etc.

[0038] In a wall unit 10 to which the mounting structure 12 is applied, when the fitting 14 is removed from the main body opening frame 16 for renovation or the like, the fitting 14 can be easily removed in the forward direction by cutting the adhesives 60a, 60b with a cutter or the like.

[0039] 6 is an enlarged vertical cross-sectional view of the upper part of the wall unit 10 to which the mounting structure 12A according to the first modification is applied. In this case, the wall unit 10 has a fin 22Aa protruding to the indoor side and a fin 22Ab protruding to the outer periphery side on the upper frame 22A constituting the frame body 18. The fin 22Aa is an extension of the wall 22Ac forming the outer periphery side visible surface of the upper frame 22A to the indoor side. The fin 22Ab is erected vertically from the wall 22Ac. The lintel 36 constituting the body opening frame 16 is almost in contact with the outer periphery side visible surfaces of the upper frame 22A and the fin 22Aa, and is almost in contact with the indoor side visible surface of the fin 22Ab.

[0040] In this case, the indoor boundary 66A is the boundary between the indoor end of the fin 22Aa and the inner peripheral visible surface of the lintel 36, and the indoor side adhesive 60a is provided in a dome-shaped cross-section so as to close the indoor boundary 66A. In addition, the outdoor boundary 68A in this case is the boundary between the outer peripheral end of the fin 22Ab and the outdoor peripheral visible surface 36b of the lintel 36, and the outdoor side adhesive 60b is provided in a dome-shaped cross-section so as to close the outdoor boundary 68A. Although the upper frame 22A has been used as an example, the same applies to the lower frame and vertical frames.

[0041] 7 is an enlarged vertical cross-sectional view of the upper part of the wall unit 10 to which the mounting structure 12B according to the second modification is applied. In this case, the wall unit 10 has a groove 74 formed along the interior boundary 66 in the lintel 36, which is a component of the frame 16 of the opening in the building frame, and the adhesive 60a on the interior side is filled in the groove 74. By providing such a groove 74, the contact area between the adhesive 60a and the lintel 36 increases, improving the fixing strength. It is preferable to provide such a groove 74 not only in the lintel 36, but also in the window sill 38 and the vertical member 35, and fill them with the adhesive 60a. Note that the groove 74 is basically provided over the entire length of each component of the frame 16 of the opening in the building frame, such as the lintel 36, but depending on the conditions, a suitable effect can be obtained by providing it at least partially.

[0042] Fig. 8 is a partially enlarged cross-sectional view of the vertical frame 26 and the vertical member 35 in the wall unit 10 to which the mounting structure 12C according to the third modification is applied. Fig. 9 is a partially enlarged schematic perspective view of the vertical frame 26 and the vertical member 35 in the wall unit 10 to which the mounting structure 12C is applied, as viewed from the room side. As shown in Figs. 8 and 9, in the mounting structure 12C, an auxiliary bracket 76 is provided across the room side boundary 66 in a part between the vertical member 35 constituting the body opening frame 16 and the vertical frame 26 constituting the frame body 18. The auxiliary bracket 76 is a slightly elongated plate material partly sandwiched between the inner peripheral side visible surface of the vertical member 35 and the outer peripheral side visible surface of the vertical frame 26.

[0043] The auxiliary bracket 76 is fixed to the interior exposed portion of the inner peripheral side concealed surface 35a of the vertical member 35 with a screw 78a, and is fixed to the outer peripheral side concealed surface 26c of the vertical frame 26 with a screw 78b. The adhesive 60a in this case is provided continuously along the interior boundary 66, but is provided across the surface of the auxiliary bracket 76 while maintaining continuity. In this way, the provision of the adhesive 60a maintains continuity, thereby maintaining good waterproofing and workability.

[0044] Since the vertical members 35 and vertical frames 26 are slightly longer than the horizontal members, if sufficient strength cannot be obtained with only the adhesive 60a, sufficient strength can be ensured by providing an appropriate number of auxiliary brackets 76. In addition, the auxiliary brackets 76 act to position the frame body 18 and the main body opening frame 16 before the adhesives 60a and 60b are applied, making it possible to stably and easily apply the adhesives 60a and 60b.

[0045] Fig. 10 is an enlarged vertical cross-sectional view of an upper portion of a wall unit to which a mounting structure 12D according to a fourth modified example is applied. Fig. 11 is an enlarged horizontal cross-sectional view of a portion of a wall unit to which a mounting structure 12D according to a fourth modified example is applied.

[0046] As shown in FIG. 10, in the mounting structure 12D, the adhesive 60a is provided across the inner peripheral side projection surface 36a of the lintel 36 and the room side facing surface 22a of the upper frame 22, and a part of the adhesive 60a penetrates between the facing surfaces 80, 80 of the lintel 36 and the upper frame 22. Also, as shown in FIG. 11, in the mounting structure 12D, the adhesive 60a is provided across the inner peripheral side projection surface 35a of the vertical member 35 and the room side facing surface 26a of the vertical frame 26, and a part of the adhesive 60a penetrates between the facing surfaces 80, 80 of the vertical member 35 and the vertical frame 26. In this way, when a part of the adhesive 60a penetrates between the facing surfaces 80, 80, the airtightness and waterproof performance are further improved. As described above, the gap between the facing surfaces 80, 80 may be substantially zero.

[0047] Fig. 12 is an enlarged vertical cross-sectional view of an upper portion of a wall unit to which a mounting structure 12E according to a fifth modified example is applied. Fig. 13 is an enlarged horizontal cross-sectional view of a portion of a wall unit to which a mounting structure 12E according to a fifth modified example is applied.

[0048] As shown in Fig. 12, in the mounting structure 12E, adhesive 60a is provided between the opposing surfaces 80, 80 of the lintel 36 and the upper frame 22 to bond both sides. In this case, adhesive 60a is not provided between the inner peripheral side facing surface 36a of the lintel 36 and the room side facing surface 22a of the upper frame 22. Also, as shown in Fig. 13, in the mounting structure 12E, adhesive 60a is provided between the opposing surfaces 80, 80 of the vertical member 35 and the vertical frame 26 to bond both sides. In this case, adhesive 60a is not provided between the inner peripheral side facing surface 35a of the vertical member 35 and the room side facing surface 26a of the vertical frame 26. Even when adhesive 60a is provided only between the opposing surfaces 80, 80 in this way, airtightness and waterproof performance can be obtained. In Figures 12 and 13, the adhesive 60a is provided so as to cover the entire surface of the opposing surfaces 80, 80, but as long as it is continuous around all four sides between the body opening frame 16 and the frame body 18, it may also be in a form in which only a portion of the space between the opposing surfaces 80, 80 is bonded.

[0049] According to the mounting structures 12, 12A to 12E described so far, with regard to the adhesive 60a on the indoor side, it is sufficient that at least one of the spaces between the opposing surfaces 80, 80 of the main body opening frame 16 and the frame body 18 and the indoor side boundary 66 is continuously sealed around all four sides by the adhesive 60a.

[0050] Fig. 14 is a vertical cross-sectional view of a wall unit to which a mounting structure 12F according to a sixth modified example is applied. Fig. 15 is a partially enlarged horizontal cross-sectional view of a wall unit to which a mounting structure 12F according to a sixth modified example is applied.

[0051] As shown in Figures 14 and 15, the mounting structure 12F corresponds to the adhesive 60b on the outdoor side, and no adhesive 60a is provided between the opposing surfaces 80, 80 or at the indoor boundary 66. In this case, an airtight material 84 such as a sponge is provided between the opposing surfaces 80, 80. The airtight material 84 is adhered to the opposing surfaces 80, 80, and has airtight and waterproof properties. The airtight material 84 is provided on all four sides between the building frame opening frame 16 and the frame body 18, and complements the effect of the adhesive 60a in each of the above embodiments.

[0052] In this way, the adhesive 60b on the outdoor side provides sufficient airtightness and waterproofness through a cooperative action with the airtight material 84, etc., even when there is no adhesive 60a on the indoor side. In the above explanation, an example was shown in which the adhesive 60b on the outdoor side is provided across the outdoor facing surface of the building frame 16 and the outdoor facing surface of the frame 18, covering the outdoor boundary 68, but the same effect can be obtained even if part or all of the adhesive 60b is provided between the opposing surfaces 82, 82. In other words, it is sufficient that the adhesive 60b is provided at least one of between the opposing surfaces 82, 82 of the building frame 16 and the frame 18 and in the location covering the outdoor boundary 68.

[0053] The mounting structure of the frame according to the present invention is a mounting structure of the frame for mounting the frame of the fitting to the frame of the opening of the building structure, characterized in that at least one of the four peripheries of the space between the opposing faces of the frame of the opening of the building structure and the frame and the interior boundary which is the interior side edge of the opposing faces is sealed with adhesive. This reduces or eliminates the number of screws and other parts required for fixing when mounting the frame of the fitting to the frame of the opening of the building structure, and further provides sufficient airtightness and waterproofness.

[0054] The mounting structure of the frame according to the present invention is characterized in that a groove is formed in the frame of the opening of the building body along at least a part of the boundary between the interior side and the building body, and the adhesive is filled in the groove. By providing such a groove, the contact area between the adhesive and the frame of the opening of the building body is increased, improving the fixing strength.

[0055] The mounting structure for the frame body according to the present invention is characterized in that an auxiliary bracket is provided between the frame body and the frame body, crossing the boundary between the interior of the room, and adhesive is provided across the surface of the auxiliary bracket. The auxiliary bracket further strengthens the fixing strength between the frame body and the frame body and also has a positioning effect relative to each other.

Even if adhesive is provided only on the outdoor side, sufficient airtightness and waterproof performance can be obtained depending on the conditions.

[0059] The mounting structure of the frame body according to the present invention is characterized in that a waterproof sheet is attached to the inner visible surface and the outdoor visible surface of the lower material constituting the structural opening frame.
