Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in order to ensure sufficient fixing strength between the building opening frame and the fitting frame, a considerable number of screws are required, and the workability during screw fixing also deteriorates. Further, when the frame is fixed to the building opening frame with screws, an airtight and waterproof structure between the building opening frame and the frame needs to be separately formed by providing a spacer, a packing material, a waterproof sheet, etc., resulting in a large number of parts and reduced workability. Therefore, the applicant has developed a mounting structure that can achieve both fixing of the frame and an airtight and waterproof structure without using screws or packing materials by fixing the frame to the building opening frame using an adhesive that is continuous around the perimeter. When fixing the frame using such an adhesive, a new problem has been confirmed that the adhesive applied to the outdoor surface of the frame deteriorates due to ultraviolet rays, rainwater, etc.

[0005] The present invention aims to provide a frame mounting structure and a wall unit that can suppress the deterioration of the adhesive used to attach the frame of a building component to a structural opening frame. [Means for solving the problem]

[0006] The present invention relates to a frame mounting structure for attaching a door frame to a structural opening frame, characterized in that the frame is positioned on the inner circumference side of the structural opening frame, the outer edge of the frame is fixed to the structural opening frame with adhesive, and a cover material is attached to the outer surface of the structural opening frame, spanning both the outer surface of the structural opening frame and the outer surface of the frame to cover the adhesive.

[0007] The present invention relates to a wall unit comprising a structural opening frame and a joinery piece installed within the structural opening frame, wherein the frame body of the joinery piece is arranged on the inner circumference side of the structural opening frame, the exterior edge of the frame body is fixed to the structural opening frame with adhesive, and a cover material is attached to the exterior surface of the structural opening frame, spanning both the exterior surface of the structural opening frame and the exterior surface of the frame body to cover the adhesive. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a frame mounting structure and a wall unit that can suppress the deterioration of the adhesive used to attach the frame of a building component to the opening frame of a building structure. [Brief explanation of the drawing]

[Figure 6]This is a cross-sectional view of the vertical frame and vertical member portion of a wall unit using a modified vertical cover material. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is an interior view of a wall unit 10, which is an embodiment of the present invention, as seen from the interior side, and Figures 2 and 3 are a longitudinal section view and a transverse section view of the wall unit 10. The wall unit 10 illustrated here is treated as a single structure when installed in a building, and is equipped with a door 1 and a structural opening frame 5. In the following description, the left-right direction of the wall unit 10 is defined as the X-axis direction, the up-down direction of the wall unit 10 is defined as the Y-axis direction, and the depth direction (indoor / outdoor direction) of the wall unit 10 is defined as the Z-axis direction. The X, Y, and Z axis directions are orthogonal to each other.

[0011] As shown in Figure 1, the structural opening frame 5 comprises an upper member, a lintel 51, a lower member, a window sill 52, and left and right vertical members 53 and 54. The window 1 is an inward-opening window and comprises a window frame 2, which is the frame body, and a sash 3 that is arranged within the window frame 2 so as to be openable and closable by hinges 26. The window frame 2 is constructed by framing an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24 around the perimeter. The sash 3 comprises an upper frame 31, a lower frame 32, left and right vertical frames 33, 34, and a facing material 35 surrounded by these. Note that in Figures 2 to 6, hatching indicating cross-sections of the main structural members of the window frame 2 and sash 3 has been omitted for the sake of clarity in the drawings.

[0012] As shown in Figures 2 and 3, the upper frame 21, lower frame 22, and left and right vertical frames 23 and 24 of the window frame 2 are formed from frame materials having the same cross-sectional shape. These frame materials are made of extruded profiles of synthetic resin and have a cross-sectional shape corresponding to the window type, which is an inward-opening window. Furthermore, recesses are formed on the outer surface of each frame material, that is, the surface facing the building opening frame 5. Brackets 40, which are positioning components, are provided on the vertical frames 23 and 24. The brackets 40 are made of metal plates, and as shown in Figure 5, the outdoor side is bent along the visible surface of the vertical frames 23 and 24 and is screwed to the vertical frames 23 and 24 with screws 48, while the indoor side is bent outwards and is in contact with the indoor surface of the vertical members 53 and 54 and is screwed to them with screws 49. The brackets 40 position the vertical frames 23 and 24, i.e., the window frame 2, in the visible direction relative to the vertical members 53 and 54, i.e., the building opening frame 5, in the visible direction. In this embodiment, the outdoor visible surface of the window frame 2 and the outdoor visible surface of the building opening frame 5 are positioned to be approximately flush. Furthermore, as shown in Figure 2, a spacer 27 is attached to the recess on the outer surface of the lower frame 22. As a result, the load applied to the lower frame 22 is supported by the window sill 52 via the lower frame 22 and the spacer 27.

[0013] The shoji screen 3 is constructed by attaching an upper frame 31, a lower frame 32, and left and right vertical frames 33 and 34 to the four sides of a rectangular surface material 35. The upper frame 31, the lower frame 32, and the left and right vertical frames 33 and 34 are extruded profiles made of synthetic resin having the same cross-sectional shape. The surface material 35 is glass. The shoji screen 3 is an inward-opening window configured such that a hinge 26 is provided between the vertical frame 34 and the vertical frame 24 located on the left side when viewed from the interior, and the shoji screen 3 opens inward around the hinge axis running vertically. The vertical frame 33 located on the right side when viewed from the interior has a handle 36 on the visible surface facing the interior.

[0014] As shown in Figure 1, the structural opening frame 5 is constructed in a frame shape, comprising a lintel 51, a window sill 52, and left and right vertical members 53 and 54. The upper ends of the vertical members 53 and 54 extend upward from the lintel 51, and the lower ends of the vertical members 53 and 54 extend downward from the window sill 52. Horizontal members 55 and 56 are attached between the upper and lower ends of the vertical members 53 and 54, respectively. The lintel 51, window sill 52, left and right vertical members 53 and 54, and horizontal members 55 and 56 are made of, for example, wood. Between the horizontal member 55 on the upper end side and the lintel 51, and between the window sill 52 and the horizontal member 56 on the lower end side, as shown in FIG. 2, heat insulating materials 57 are respectively arranged. Further, a surface material 58 is attached to the outdoor surface of the building opening frame 5. Depending on the relationship between the height dimension of the wall surface unit 10 and the height dimension of the fitting 1, the building opening frame 5 may be configured without providing one or both of the horizontal members 55 and 56.

[0015] The lintel 51, the vertical members 53 and 54, and the horizontal members 55 and 56 are formed in a rectangular cross-sectional shape. On the other hand, the window sill 52 is formed in a shape with a stepped portion 521 formed on the outdoor side. That is, the window sill 52 has an upper surface on which the lower frame 22 is placed, a vertical surface provided downward from the outdoor end of the upper surface, and a horizontal surface provided toward the outdoor side from the lower end of the vertical surface. Thereby, a stepped portion 521 partitioned by the vertical surface and the horizontal surface is formed on the window sill 52. A waterproof sheet 59 is attached from the upper surface of the window sill 52 to the surface material 58 provided on the outdoor side of the window sill 52 via the vertical surface and the horizontal surface.

[0016] The upper frame 21, the vertical frames 23 and 24 of the window frame 2 arranged on the inner peripheral side of the building opening frame 5 are fixed to the lintel 51, the vertical members 53 and 54 with an adhesive 61 on the indoor side and an adhesive 62 on the outdoor side. Further, the lower frame 22 is fixed to the window sill 52 with an adhesive 61 on the indoor side. In order to smoothly arrange the window frame 2 in the opening of the building opening frame 5, the opening dimension of the building opening frame 5 is slightly larger than the dimension of the window frame 2. For this reason, when the lower frame 22 is placed on the upper surface of the window sill 52, a slight gap is generated between the upper frame 21 and the lintel 51, and between the vertical frames 23 and 24 and the vertical members 53 and 54. For this reason, as also shown in FIGS. 4 and 5, a part of the adhesives 61 and 62 is also filled in the gap portion.

[0017] The indoor adhesive 61 is provided across the indoor surfaces of the upper frame 21, the lower frame 22, and the vertical frames 23 and 24, and the inner peripheral surfaces of the sill 51, the window sill 52, and the vertical members 53 and 54. This adhesive 61 is provided continuously around the four sides over the entire lengths of the upper frame 21, the lower frame 22, and the vertical frames 23 and 24. Note that since the adhesive 61 is applied across two surfaces that are cross-arranged between the indoor surface of the window frame 2 and the inner peripheral surface of the opening of the building body opening frame 5, its cross-sectional shape is substantially triangular. Therefore, even in the portion where the thin plate-shaped bracket 40 is arranged, the adhesive 61 is continuously applied across the bracket 40. As described above, the indoor adhesive 61 is fixed by continuously closing the indoor-side gap between the building body opening frame 5 and the window frame 2 around the four sides, ensuring airtightness and watertightness, and enabling the window frame 2 to be firmly fixed.

[0018] The outdoor adhesive 62 is provided across the outdoor surfaces of the upper frame 21 and the vertical frames 23 and 24, and the outdoor surfaces of the sill 51 and the vertical members 53 and 54, and is not provided between the lower frame 22 and the window sill 52. That is, since the adhesive 61 is provided over the entire lengths of the upper frame 21 and the vertical frames 23 and 24 and is fixed by continuously closing the gaps on three sides excluding the lower frame 22 portion among the four sides, the airtightness and watertightness of these gap portions are further improved, and the fixing strength of the window frame 2 is also improved. outside

[0019] The adhesives 61 and 62 can be used as long as they can fix the window frame 2 to the building body opening frame 5. For example, various adhesives such as hot melt type, two-component mixed type, and moisture effect type can be used. The adhesive 61 and the adhesive 62 may be of the same type or different types. Also, different types of the adhesive 61 may be used depending on the application location, and similarly, different types of the adhesive 62 may be used depending on the application location.

[0020] As shown in FIGS. 2 and 3, an upper cover member 81, a water drainage member 82, and vertical cover members 83 and 84 are attached to the outdoor surface of the building body opening frame 5.

[0021] As shown in Figure 4, the upper cover material 81 is composed of a fixing piece 811 fixed to the surface material 58, a trim piece 812 extending outward from the fixing piece 811, and a covering piece 813 extending downward from the base end of the trim piece 812. Protruding pieces 8111 and 8112 are formed on the upper edge of the fixing piece 811 and at approximately the midpoint in the vertical direction, projecting toward the interior side, and the screws 819 for fixing the upper cover material 81 are positioned between the protruding pieces 8111 and 8112. The trim piece 812 comprises a horizontal surface portion 8121 continuous with the fixing piece 811, an inclined surface portion 8122 continuous with the horizontal surface portion 8121 and extending diagonally downward, and a vertical surface portion 8123 extending downward from the outdoor end of the inclined surface portion 8122. A screw hole 814 is formed on the lower surface of the trim piece 812. Screws (not shown) that connect the vertical cover members 83, 84 and the upper cover member 81 are screwed into this screw hole 814. The covering piece 813 is formed in a roughly L-shape in cross-section, with its lower end protruding towards the interior of the room. The fixing piece 811 and covering piece 813 of the upper cover material 81 are positioned across the exterior surface of the structural opening frame 5 and the exterior surface of the upper frame 21, and are located on the exterior side of the adhesive 62. Therefore, the upper cover material 81 is used as a cover material to prevent the adhesive 62 that fixes the upper frame 21 to the structural opening frame 5 from being exposed on the exterior side. In addition, since the trim piece 812 is positioned opposite the end surface of the exterior material 91, which will be described later, it is also used as a trim material to trim the exterior material 91.

[0022] As shown in Figure 2, the flashing material 82 is placed on the stepped portion 521 of the windowsill 52 with a waterproof sheet 59 sandwiched in between. The flashing material 82 is composed of an inclined piece portion 821 extending diagonally downward, a tip portion 822 extending downward from the outdoor end of the inclined piece portion 821, and a fixing piece portion 823 that is arranged along the surface material 58 and fixed to the surface material 58 and the windowsill 52 with screws 829. Two screw holes are formed on the underside of the inclined piece 821 of the flashing material 82. Screws (not shown) that connect the vertical cover materials 83 and 84 to the flashing material 82 are screwed into the screw holes on the exterior side. Screws (not shown) that secure the cover materials that close the openings at both ends of the hollow section of the flashing material 82 are screwed into the screw holes on the interior side. Furthermore, since a portion of the lower frame 22 is positioned above the stepped portion 521 of the window sill 52, the portion of the flashing material 82 positioned on the stepped portion 521 overlaps with the lower frame 22 in a plan view. Also, as shown in Figures 2 and 5, the outdoor end of the inclined piece 821 protrudes further outward than the vertical cover materials 83 and 84, and an end cap 85 is attached to close the end of this protruding portion.

[0023] Since the vertical cover members 83 and 84 have the same symmetrical cross-sectional shape, the structure will be explained using the vertical cover member 84 shown in Figure 5. The vertical cover material 84 comprises a fixing piece 841 fixed to the surface material 58, a trim piece 842 extending outward from the fixing piece 841, and a retaining piece 843 extending inward from the base end of the trim piece 842. Protruding pieces 8411 and 8412 are formed on the outer edge of the fixing piece 841 and at approximately the midpoint in the left-right direction, projecting toward the interior side, and the screws 849 that fix the vertical cover members 83 and 84 are positioned between the protruding pieces 8411 and 8412. The trim piece 842 is formed in a roughly L-shape in cross-section, with its outdoor-facing end protruding outwards. The retaining piece 843 has a retaining groove 8431 that holds the water-stopping member 86 which abuts against the outdoor surface of the vertical frames 23 and 24. The water-stopping member 86 is made of AT (Airtight) material. The fixing pieces 841 of the vertical cover members 83 and 84 are positioned across the exterior surface of the structural opening frame 5 and the exterior surface of the vertical frames 23 and 24, and are located on the exterior side of the adhesive 62. Therefore, the vertical cover members 83 and 84 function as cover materials that prevent the adhesive 62 that fixes the vertical frames 23 and 24 to the structural opening frame 5 from being exposed on the exterior side. In addition, since the trim piece 842 is positioned opposite the end surface of the exterior material 91, which will be described later, it can also be used as a trim material to trim the exterior material 91.

[0024] As shown in Figures 4 and 5, waterproof tapes 71, 72 and waterproof sheet 73 are applied to the exterior surface of the structural opening frame 5. The waterproof tape 71 has an adhesive surface on one side facing the surface material 58, and is applied from the surface material 58 to the surface of the adhesive 62. This prevents water from seeping in between the surface material 58 and the adhesive 62. The waterproof tape 72 has adhesive surfaces on both sides and is applied from the waterproof tape 71 to the surface of the upper cover material 81 and the vertical cover materials 83 and 84. The waterproof sheet 73 is applied from the surface material 58 to the surface of the waterproof tape 72. These waterproof tapes 72 and waterproof sheets 73 prevent water from seeping in between the upper cover material 81, the vertical cover materials 83 and 84 and the surface material 58.

[0025] As shown in Figures 2 and 3, exterior cladding 91 is attached to the exterior side of the structural opening frame 5 via vertical furring strips 92 and horizontal furring strips 93. The exterior cladding 91 is attached except for the opening portion partitioned by the upper cover material 81, flashing material 82, and vertical cover materials 83 and 84. Backup material 75 and sealing material 76 are placed between the exterior cladding 91 and the upper cover material 81 and vertical cover materials 83 and 84. Backup material 75 and sealing material 76 are also placed between the flashing material 82 and the lower surface of the lower frame 22. Interior finishing material 94 is attached to the interior side of the structural opening frame 5, except for the opening where the door 1 will be placed. In addition, a trim frame 95 is attached to all four sides of the inner surface of the opening of the structural opening frame 5 to define the interior finishing material 94.

[0026] [Assembly process for wall units] Next, we will explain the process of assembling the wall unit 10. At the factory where joinery 1 is manufactured, joinery 1 is assembled. Since this assembly method is the same as for general joinery 1, the explanation is omitted. In the assembly plant for the structural opening frame 5, the lintel 51, window sill 52, left and right vertical members 53, 54, and horizontal members 55, 56 are framed, the surface material 58 is attached, and the insulation material 57 is placed to assemble the structural opening frame 5.

[0027] Next, at the assembly plant for the wall unit 10, the joinery 1 is attached to the structural opening frame 5 to assemble the wall unit 10. The assembly of the wall unit 10 may be carried out at the same factory as the manufacturing plant for the joinery 1 and the assembly plant for the structural opening frame 5, or at a different factory. To construct a wall unit 10 by attaching the window frame 2 of the joinery 1 to the structural opening frame 5, the bracket 40 is fixed to the window frame 2 with screws 48, and the bracket 40 is fixed to the structural opening frame 5 with screws 49 to position the window frame 2. Then, the interior side of the window frame 2 is fixed to the structural opening frame 5 with adhesive 61, and the exterior side of the window frame 2 is further fixed to the structural opening frame 5 with adhesive 62. In addition, a waterproof sheet 59 is attached from the window sill 52 to the surface material 58. Although the dispensing of adhesives 61 and 62 can be done manually by an operator, since the wall unit 10 is assembled in the factory, it can be automated using robots or the like.

[0028] [On-site installation work for wall units] The wall unit 10 is completed by the assembly work described above. The method for transporting this wall unit 10 to the construction site and installing it on a building such as a house can be done in the same way as in Patent Documents 1 and 2, so a detailed explanation is omitted. After the wall unit 10 is installed in a house or the like, waterproof tape 71 is applied to the surface of the surface material 58 and adhesive 62, and then the upper cover material 81, flashing material 82, and vertical cover materials 83 and 84 are installed. At this time, the upper cover material 81, flashing material 82, and vertical cover materials 83 and 84 may be installed in a four-sided assembled state on the structural opening frame 5, or each component may be installed on the structural opening frame 5 individually. Furthermore, before installing the wall unit 10 in a house or the like, for example, during the assembly of the wall unit 10 at the factory, or after transporting the wall unit 10 to the construction site and before installing it in the house, the waterproof tape 71, upper cover material 81, flashing material 82, and vertical cover materials 83 and 84 may be attached to the wall unit 10. Furthermore, after applying waterproof tape 72 and waterproof sheet 73 to the surfaces of the upper cover material 81 and vertical cover materials 83 and 84, the vertical furring strips 92 and horizontal furring strips 93 are attached and the exterior material 91 is installed. Then, backup material 75 and sealing material 76 are placed to seal the gaps between the exterior material 91 and the upper cover material 81 and vertical cover materials 83 and 84, and between the lower frame 22 and the flashing material. Finally, interior material 94 and frame 95 are attached to the interior side of the wall unit 10 to finish it.

[0029] [Effects of the Embodiment] According to this embodiment, since the adhesive 62 on the exterior side is covered by the upper cover material 81 and the vertical cover materials 83 and 84, the adhesive 62 can be protected from ultraviolet rays and water, and the deterioration of the adhesive 62 can be suppressed. Furthermore, since the adhesive is covered by the upper cover material 81 and the vertical cover materials 83 and 84 and is not exposed to the outside, a decrease in design quality can also be prevented. The adhesive 61 on the interior side is applied along the interior edge of the window frame 2 and is further concealed by the frame 95, so it is not exposed to ultraviolet rays or rainwater, thus preventing deterioration and maintaining the aesthetic appeal. By bringing the water-stopping members 86 provided on the vertical cover materials 83 and 84 into contact with the exterior surfaces of the vertical frames 23 and 24, water can be prevented from seeping in between the vertical cover materials 83 and 84 and the vertical frames 23 and 24, thereby further suppressing the deterioration of the adhesive 62. The adhesive 62 is covered with waterproof tape 71, and the space between the upper cover material 81, vertical cover materials 83, 84 and the structural opening frame 5 is also covered with waterproof tape 72 and waterproof sheet 73. This prevents water from seeping in from the contact area between the upper cover material 81, vertical cover materials 83, 84 and the structural opening frame 5, and further suppresses the deterioration of the adhesive 62.

[0030] The upper cover material 81 has protruding pieces 8111 and 8112, and the vertical cover materials 83 and 84 have protruding pieces 8411 and 8412. Screws 819 and 849 are provided between these protruding pieces 8111, 8112 and protruding pieces 8411, 8412 to secure them. As a result, the adhesive 62 is not crushed by the upper cover material 81 or the vertical cover materials 83 and 84, and damage to the adhesive 62 is also prevented. The upper cover material 81 and the vertical cover materials 83 and 84 are equipped with trim pieces 812 and 842, and therefore also function as trim pieces to trim the edges of the exterior material 91. As a result, the number of parts can be reduced compared to the case where the cover material that covers the adhesive 62 and the trim piece for the exterior material 91 are provided separately, and the workability of the installation can also be improved. Since the inclined portion 821 of the flashing material 82 protrudes further outward than the vertical cover materials 83 and 84, water flowing on the upper surface of the inclined portion 821 can be discharged outside the vertical cover materials 83 and 84, and water flowing from the flashing material 82 into the space between the exterior material 91 and the structural opening frame 5, which are located below the flashing material 82, can be easily prevented.

[0031] The adhesive 61 that secures the interior side of the window frame 2 is applied continuously around all four sides of the window frame 2. In addition to securing the window frame 2, this adhesive 61 also provides airtight and waterproofing, eliminating the need for screws and gaskets used in conventional window frame 2 installations. As a result, the number of parts can be reduced by omitting or minimizing the use of screws and gaskets. Furthermore, compared to securing the window frame 2 with screws and attaching gaskets to ensure airtightness and waterproofing, applying adhesive 61 to secure the window frame 2 reduces working time, thereby improving the assembly efficiency of the wall unit 10. Since the adhesive 62 that secures the exterior side of the window frame 2 is continuously applied to three sides of the upper frame 21 and the vertical frames 23 and 24, the fixing strength of the window frame 2 can be further improved, and the airtightness and waterproofness of the upper frame 21 and the vertical frames 23 and 24 can be improved. Since the adhesives 61 and 62 are not only applied across the surfaces of the window frame 2 and the structural opening frame 5, but are also partially filled between the opposing surfaces of the window frame 2 and the structural opening frame 5, the fixing strength of the window frame 2 by the adhesives 61 and 62 can be further improved. Furthermore, since brackets 40 are provided that are fixed to the vertical frames 23 and 24 and the vertical members 53 and 54 with screws 48 and 49, the fixing strength of the window frame 2 can be further improved. In addition, by using brackets 40, the window frame 2 can be easily positioned relative to the structural opening frame 5 and adhesive 61 and 62 can be applied, which also improves work efficiency.

[0032] The height of the window frame 2 is slightly greater than the height of the opening of the structural opening frame 5, and the width of the window frame 2 in the left-right direction (X direction) is slightly greater than the width of the opening of the structural opening frame 5. Therefore, the window frame 2 can be easily placed inside the structural opening frame 5. Furthermore, when replacing the door 1 during renovations, the door 1 can be easily removed from the structural opening frame 5 in the depth direction by cutting the adhesives 61 and 62 with a cutter, thereby improving work efficiency during renovations.

[0033] [Differentiation] The present invention is not limited to the configurations described in the embodiments above, and any modifications that can achieve the objectives of the present invention are included in the present invention. For example, a vertical cover member 84B as shown in Figure 6 may be used. The vertical cover member 84B differs from vertical cover members 83 and 84 in that it has a retaining piece 843B that is bent into a roughly L-shape in cross-section, and a sponge water-stopping member 87 is placed in a retaining groove 8431B partitioned by this retaining piece 843B. However, the other structures are the same, so they are given the same reference numerals and their explanation is omitted. Although not shown in the figure, the vertical cover member that spans the vertical frame 23 and the vertical member 53 also has the same cross-sectional shape as the vertical cover member 84B, being symmetrical on both sides. Even when using this vertical cover material 84B, the deterioration of the adhesive 62 can be suppressed by covering it, and the water-stopping member 87 adheres tightly to the exterior surface of the vertical frames 23 and 24, preventing water from seeping in between the vertical cover material 84B and the vertical frames 23 and 24.

[0034] In the above embodiment, the upper cover material 81 and vertical cover materials 83 and 84 are equipped with trim pieces 812 and 842. However, depending on the arrangement of the exterior material 91, cover materials without trim pieces may be used as long as they can cover the adhesive 62.

[0035] The vertical cover materials 83, 84, and 84B are not limited to those equipped with water-stopping members 86 and 87, and may be cover materials without water-stopping members 86 and 87 and retaining pieces 843 and 843B. In this case, the waterproof tape 71 may be applied to the exterior surface of the vertical frames 23 and 24, so that the adhesive 62 is completely covered with the waterproof tape 71. The window frame 2 is not limited to those equipped with brackets 40. For example, if the window frame 2 can be positioned using a jig or the like when bonding it to the structural opening frame 5 with adhesives 61 and 62, then brackets 40 do not need to be provided.

[0036] The window frame 2 and shoji screen 3 of the joinery 1 are not limited to being made of synthetic resin, but may also be made of extruded metal profiles such as aluminum. The joinery 1 is not limited to inward-opening windows; various types of joinery can be used, such as fixed windows, outward-opening windows, and double-hung windows. In the case of a fixed window, the frame material that holds the glass is directly fixed to the structural opening frame 5, so the frame material becomes the frame itself.

[0037] In the above embodiment, the exterior side of the lower frame 22 and the window sill 52 are not fixed with adhesive 62, but the lower frame 22 and the window sill 52 may also be fixed with adhesive 62. For example, a stepped portion 521 can not be formed on the window sill 52, the upper surface of the surface material 58 can be placed at the same height as the upper surface of the window sill 52, and adhesive 62 can be applied across the surface material 58 and the exterior side of the lower frame 22 to fix them in place. In this case, a flashing material can be placed across the surface material 58, which is the exterior side of the building frame opening 5, and the exterior side of the lower frame 22, and this flashing material can be used as a cover material to cover the adhesive 62.

[0038] In the above embodiment, the work of attaching the window frame 2 to the structural opening frame 5 with adhesives 61 and 62 was performed at the factory, but it may also be performed at the construction site. For this reason, the structural opening frame 5 is not limited to a transportable unit, but may also be composed of columns, studs, and lintels and window sills attached to these columns, which are part of the house's structure. In other words, the joinery 1 may be transported to the construction site and directly attached to the opening in the house's structure. Furthermore, the present invention only requires the use of a cover material to suppress the deterioration of the adhesive 62 on the exterior side to which the window frame 2 is attached. Therefore, the adhesive 61 on the interior side is not essential.

[0039] [summary] The present invention relates to a frame mounting structure for attaching a door frame to a structural opening frame, characterized in that the frame is positioned on the inner circumference side of the structural opening frame, the outer edge of the frame is fixed to the structural opening frame with adhesive, and a cover material is attached to the outer surface of the structural opening frame, spanning both the outer surface of the structural opening frame and the outer surface of the frame to cover the adhesive. According to the present invention, since the adhesive used to attach the frame of the joinery to the structural opening frame is covered with a cover material, the adhesive can be protected from ultraviolet rays and water, thereby suppressing the deterioration of the adhesive. Furthermore, since the frame can be fixed to the structural opening frame with adhesive, the use of screws and gaskets can be reduced or omitted, improving the ease of installing the joinery.

[0040] In the frame mounting structure of the present invention, the cover material is characterized by having a water-stopping member that abuts against the outdoor surface of the frame. Since the water-stopping member provided on the cover material is in contact with the exterior surface of the frame, water seepage between the cover material and the frame can be prevented, and the deterioration of the adhesive can be further suppressed.

[0041] In the frame mounting structure of the present invention, an exterior material is arranged on the exterior side of the structural opening frame, and the cover material is characterized in that it has a trim piece facing the end surface of the exterior material. The cover material has a trim piece, so it also functions as a trim piece to finish off the edges of the exterior material. Therefore, the number of parts can be reduced compared to when the cover material that covers the adhesive and the trim piece for the exterior material are provided separately, and the workability of the installation can be improved.

[0042] In the frame mounting structure of the present invention, the frame opening is composed of an upper member, a lower member, and left and right vertical members, the frame is composed of an upper frame, a lower frame, and left and right vertical frames, the adhesive is continuously provided between the upper frame and the upper member, and between the vertical frames and the vertical members, the cover material comprises an upper cover material that covers the adhesive between the upper frame and the upper member, and a vertical cover material that covers the adhesive between the vertical frames and the vertical members, a flashing material is attached to the lower member, and the flashing material protrudes outward from the vertical cover material. Since adhesive is continuously applied between the upper frame and the upper member, and between the vertical frame and the vertical member, the watertightness and waterproofness of the upper frame and vertical frame portions can be improved, and the fixing strength of the frame can also be improved. Furthermore, by attaching a flashing material to the lower part of the structural opening frame and making this flashing material protrude further outward than the vertical cover material, water flowing over the top surface of the flashing material can be discharged outside the vertical cover material.

[0043] The present invention relates to a wall unit comprising a structural opening frame and a joinery piece installed within the structural opening frame, wherein the frame of the joinery piece is positioned on the inner circumference side of the structural opening frame, the exterior edge of the frame is fixed to the structural opening frame with adhesive, and a cover material is attached to the exterior surface of the structural opening frame, spanning both the exterior surface of the structural opening frame and the exterior surface of the frame to cover the adhesive. According to the present invention, similar to the mounting structure for the joinery, the adhesive used to attach the frame of the joinery to the structural opening frame is covered with a cover material, thereby protecting the adhesive from ultraviolet rays and water, and suppressing the deterioration of the adhesive. Furthermore, since the frame can be fixed to the structural opening frame with adhesive, the use of screws and gaskets can be reduced or omitted, improving the ease of installing the joinery.
