Modes for Carrying Out the Invention

[0017] Hereinafter, embodiments of the frame structure, sash frame mounting structure, and building according to the present invention will be described with reference to the drawings. In each figure, identical components are denoted by the same reference numerals.

[0018] Figure 1 is a front view showing a sash frame mounting structure 100 as one embodiment of the sash frame mounting structure according to the present invention. The sash frame mounting structure 100 comprises a sash frame 101, a frame structure 102 as one embodiment of the frame structure according to the present invention, and a structural frame 103 of a building 200. The sash frame 101 is installed in an opening formed in the exterior wall material of the exterior wall of the building 200. The sash frame 101 is arranged along the periphery end face of the opening. The sash frame 101 holds a facing material 105, such as an openable and closable door or a fixed panel. The frame structure 102 is configured to allow the sash frame 101 to be attached to the structural frame 103 of the building 200. The structural frame 103 of the building 200 includes, for example, the framework of the building 200, including columns and beams.

[0019] First, an overview of the building 200 in this embodiment will be described. The building 200 can be, for example, a two-story detached house with a steel frame. Such a building 200 comprises, for example, a foundation structure such as a reinforced concrete strip foundation supported by the ground, and a superstructure that has a frame made up of frame members such as column members and beam members and is supported by the foundation structure. The frame members that make up the frame can be pre-standardized members that are manufactured in a factory beforehand and then transported to the construction site for assembly. However, the building 200 may also be a wooden house constructed using so-called conventional construction methods. Furthermore, the building 200 is not limited to two stories, but may have one floor or three or more floors. Moreover, the building 200 is not limited to a detached house, but may also be, for example, an apartment building.

[0020] The superstructure of this embodiment comprises a frame composed of a plurality of columns and a plurality of beams erected between these columns, an outer wall arranged on the outer periphery of this frame, and a floor supported by the beams of the frame.

[0021] The exterior side of the exterior wall is composed of connected exterior wall panels. On the interior side of the exterior wall panels, insulation material and interior wall material that constitute the insulation layer are arranged.

[0022] For the exterior wall panels, for example, panels made of autoclaved light weight concrete (hereinafter referred to as "ALC," which stands for "autoclaved light weight concrete"), metal or ceramic siding, extruded cement boards, or wood-based panels can be used. By connecting these exterior wall panels around the outer perimeter of the frame, the outer shell layer of the exterior wall can be formed.

[0023] Furthermore, as insulation materials, in addition to panel-shaped insulation materials made of foamed resin-based materials such as phenolic foam, polystyrene foam, and urethane foam, fibrous insulation materials such as rock wool can also be used. By arranging this insulation material on the indoor side of the exterior wall panel, along the inner surface of the exterior wall panel, an insulation layer can be formed on the exterior wall. As interior wall material, for example, gypsum board can be used, and by connecting the interior wall material to the indoor side of the outer perimeter of the frame, an inner skin layer can be formed.

[0024] The floor includes floor slab material. The floor slab material is erected between the beams of the frame and is supported directly or indirectly by the beams. As floor slab material, for example, ALC panels can be used, but other materials such as folded plates, extruded cement boards, and wood panel materials may also be used. In addition to floor slab material, the floor may also include, for example, ceiling interior materials that form the ceiling surface of the floor below, which are attached directly or indirectly to the floor slab material, and floor interior materials such as flooring that form the floor surface of the floor above, which are laminated on the floor slab material.

[0025] Furthermore, the roof of building 200 may be a flat roof. While ALC panels may be used for the roof slab material constituting the flat roof, it is not limited to ALC panels. The roof slab material is also waterproofed by being covered with a waterproof sheet, for example, made of polyvinyl chloride resin. Additionally, the roof of building 200 is not limited to a flat roof; it may also be a pitched roof using roofing materials such as slate.

[0026] Next, we will explain the details of the sash frame mounting structure 100.

[0027] In the sash frame mounting structure 100 shown in Figure 1, the frame structure 102 to which the sash frame 101 is attached is attached to the structural frame 103 of the building 200. The frame structure 102 comprises a frame body 10 and a height adjustment member 20. The frame body 10 is configured to be attachable to the structural frame 103 so that its own weight is supported by the structural frame 103. The height adjustment member 20 is movably attached to the frame body 10 and is configured to adjust the height position of the frame body 10 relative to the structural frame 103.

[0028] More specifically, in this embodiment, the frame body 10 is attached to the upper beam 103b, which is part of the structural frame 103, while its own weight is supported by the lower beam 103a, which is part of the structural frame 103. As shown in Figure 1, the frame body 10 in this embodiment is attached to the upper beam 103b indirectly via mounting brackets 104, but the configuration is not limited to this. The frame body 10 may be attached to the upper beam 103b directly, for example, without using mounting brackets 104. The mounting brackets 104 may be fastened to the frame body 10 and the upper beam 103b, respectively, using fastening members such as bolts and screws.

[0029] In this embodiment, the lower beam 103a and upper beam 103b are H-shaped steel, but the cross-sectional shape of the lower beam 103a and upper beam 103b is not limited to the configuration of this embodiment.

[0030] Furthermore, although the frame body 10 shown in Figure 1 abuts against the lower beam 103a, which is part of the structural frame 103, and is directly supported vertically downward by the lower beam 103a, the configuration is not limited to this. The frame body 10 may not abut against the lower beam 103a, but may be indirectly supported vertically downward by the lower beam 103a, for example, via mounting brackets or the like.

[0031] Furthermore, although the frame body 10 of this embodiment is attached to the upper beam 103b as a structural frame 103, as described above, the configuration is not limited to this. The frame body 10 may be attached to a structural frame 103 other than the upper beam 103b. Also, although the frame body 10 of this embodiment is supported by the lower beam 103a as a structural frame 103, as described above, the configuration is not limited to this. The frame body 10 may be supported by a structural frame 103 other than the lower beam 103a.

[0032] Thus, the frame body 10 is configured to be attachable to the structural frame 103 of the building 200 while its own weight is supported by the structural frame 103.

[0033] The height adjustment element 20 is configured to adjust the vertical height position of the frame body 10 relative to the structural frame 103 according to the state of the structural frame 103. As will be described in detail later, the height adjustment element 20 in this embodiment is a height adjustment bolt 20a. The frame body 10 in this embodiment is provided with a nut portion 13 into which the height adjustment bolt 20a, which serves as the height adjustment element 20, can be screwed.

[0034] Here, the frame body 10 is configured to allow selection between a first support state and a second support state depending on the state of the structural frame 103. The "first support state" means a state in which the frame body 10 is supported by the structural frame 103 without the height adjustment body 20 adjusting its height relative to the structural frame 103. Figure 1 shows the frame body 10 in the first support state. The "second support state" means a state in which the frame body 10 is supported by the structural frame 103 via the height adjustment body 20 after the height adjustment body 20 has adjusted its height relative to the structural frame 103. Figure 2 shows a sash frame mounting structure 100 in which the frame body 10 is supported by the structural frame 103 in the second support state.

[0035] Figure 1 shows an example where the lower beam 103a and upper beam 103b, as structural members 103, extend parallel to each other horizontally at different vertical positions. In contrast, Figure 2 shows an example where the lower beam 103a and upper beam 103b, as structural members 103, do not extend parallel to each other horizontally at different vertical positions. More specifically, in Figure 2, the upper beam 103b extends horizontally, while the lower beam 103a extends in a direction inclined with respect to the horizontal. Note that in Figure 2, for the sake of explanation, the inclination angle of the lower beam 103a with respect to the horizontal is exaggerated. Thus, the state of the structural members 103 to which the frame structure 102 is attached may vary slightly even within the allowable range due to, for example, the dimensional tolerances of the members constituting the structural members 103, construction accuracy, etc. In such cases, the frame body 10 is configured to allow adjustment of its height relative to the structural frame 103 by the height adjustment member 20.

[0036] Specifically, the height adjustment member 20 of this embodiment is configured to allow adjustment of the height position of the frame body 10 relative to the lower beam 103a. More specifically, the height adjustment member 20 of this embodiment is configured to allow adjustment of the amount of vertical downward protrusion from the frame body 10. When the frame body 10 shown in Figure 1 is in the first support state, the height adjustment member 20 of this embodiment is in an unengaged state, not engaging with the lower beam 103a. In contrast, when the frame body 10 shown in Figure 2 is in the second support state, the height adjustment member 20 of this embodiment protrudes vertically downward from the aforementioned unengaged state and engages with the lower beam 103a, lifting the frame body 10 vertically upward from the lower beam 103a. By providing such a height adjustment member 20, the height position of the frame body 10 relative to the structural frame 103 can be adjusted. Therefore, in cases where the structural frame 103 cannot support the frame body 10 in the desired position, such as the lower beam 103a which is inclined horizontally as shown in Figure 2, the height adjustment member 20 can be used to adjust the height position of the frame body 10 relative to the structural frame 103. This absorbs variations in the structural frame 103, such as the inclination of the lower beam 103a in the horizontal direction as shown in Figure 2, and allows the frame body 10 to be attached to the structural frame 103 in the desired position. Conversely, as shown in Figure 1, if the structural frame 103 can support the frame body 10 in the desired position, the height adjustment member 20 does not need to be used.

[0037] As described above, the frame body 10 is configured to allow selection of two states depending on the state of the structural frame 103: a first support state in which the frame body 10 is supported by the structural frame 103 without its height being adjusted by the height adjustment body 20, and a second support state in which the frame body 10 is supported by the structural frame 103 via the height adjustment body 20 when its height is being adjusted by the height adjustment body 20. As a result, for example, as shown in Figure 1 with the lower beam 103a and upper beam 103b, when the state of the structural frame 103 is such that it can support the frame body 10 in a desired position, the frame body 10 is supported by the structural frame 103 without using the height adjustment body 20 (first support state). In contrast, if the structural frame 103 is in a state where it cannot support the frame body 10 in the desired position, such as the lower beam 103a inclined horizontally as shown in Figure 2, the frame body 10 can be set to the desired position using the height adjustment member 20, and its own weight is supported by the structural frame 103 via the height adjustment member 20 (second support state).

[0038] Furthermore, by using the height adjustment member 20 only when height adjustment of the frame body 10 relative to the structural frame 103 is necessary, the effort required for attaching the frame body 10 to the structural frame 103 can be reduced.

[0039] As shown in Figure 2, the mounting configuration of the frame body 10, whose height is adjusted by the height adjustment member 20, to the structural frame 103 is the same as in Figure 1. In other words, the frame body 10 of this embodiment is attached to the upper beam 103b, which is part of the structural frame 103, while its own weight is supported by the lower beam 103a, which is part of the structural frame 103, not only in the first support state shown in Figure 1, but also in the second support state shown in Figure 2. As shown in Figures 1 and 2, the frame body 10 of this embodiment is attached to the upper beam 103b indirectly via the mounting bracket 104, regardless of whether it is in the first or second support state, but the configuration is not limited to this. The frame body 10 may be configured to be attached directly to the upper beam 103b without using the mounting bracket 104, for example, regardless of whether it is in the first or second support state.

[0040] Furthermore, although the height adjustment body 20 shown in Figure 2 is in contact with the lower beam 103a as part of the structural frame 103, the configuration is not limited to this. The height adjustment body 20 may not be in contact with the lower beam 103a, but for example, it may be in contact with a mounting bracket fastened to the lower beam 103a by fastening members such as bolts and screws. In other words, the frame body 10 in the second support state only needs to be supported vertically downward by the lower beam 103a via the height adjustment body 20, and the height adjustment body 20 may be configured to be in contact with the lower beam 103a or not (see Figure 8).

[0041] Furthermore, although the frame body 10 of this embodiment is attached to the upper beam 103b as a structural frame 103 in both the first and second support states (see Figures 1 and 2), the configuration is not limited to this. The frame body 10 may be attached to a structural frame 103 other than the upper beam 103b. Also, as described above, even in the second support state, the frame body 10 of this embodiment is supported by the lower beam 103a as a structural frame 103, but the configuration is not limited to this. The weight of the frame body 10 may be supported by a structural frame 103 other than the lower beam 103a in both the first and second support states.

[0042] Further details of the sash frame mounting structure 100 of this embodiment will be described below with reference to Figures 1 to 3. Figure 3 shows the state in which the frame body 10 shown in Figure 2 is supported by the lower beam 103a shown in Figure 2 without the use of the height adjustment body 20. In other words, the frame body 10 of this embodiment is adjusted in height by the height adjustment body 20 from the state shown in Figure 3 to the desired position shown in Figure 2, and then attached to the upper beam 103b.

[0043] As shown in Figures 1 to 3, the frame body 10 of this embodiment is formed in a frame shape so as to follow the sash frame 101. More specifically, the frame body 10 of this embodiment comprises two horizontal frame sections 11 and two vertical frame sections 12.

[0044] The two horizontal frame sections 11 extend in a substantially horizontal direction when the frame body 10 is attached to the structural frame 103. The two horizontal frame sections 11 in this embodiment include an upper horizontal frame section 11a to which the upper frame 101a of the sash frame 101 is attached and which extends along the upper frame 101a, and a lower horizontal frame section 11b to which the lower frame 101b of the sash frame 101 is attached and which extends along the lower frame 101b.

[0045] In this embodiment, the frame body 10 is attached to the structural frame 103 by having the upper horizontal frame portion 11a attached to the upper beam 103b via mounting brackets 104. As shown in Figures 1 to 3, the upper horizontal frame portion 11a in this embodiment is configured to allow the attachment of multiple mounting brackets 104 at different positions in its extending direction. However, the attachment positions of the mounting brackets 104 and the number of mounting brackets 104 attached to the upper horizontal frame portion 11a are not particularly limited.

[0046] The two vertical frame sections 12 extend substantially vertically when the frame body 10 is attached to the structural frame 103. The two vertical frame sections 12 in this embodiment include a left vertical frame section 12a to which the left vertical frame 101c of the sash frame 101 is attached and which extends along the left vertical frame 101c, and a right vertical frame section 12b to which the right vertical frame 101d of the sash frame 101 is attached and which extends along the right vertical frame 101d. Here, "left vertical frame" means the vertical frame located on the left side of the sash frame 101 in a front view of the sash frame mounting structure 100 viewed from the outside towards the inside (hereinafter simply referred to as "front view"). Also, "right vertical frame" means the vertical frame located on the right side of the sash frame 101 in a front view of the sash frame mounting structure 100. Furthermore, the left vertical frame section 12a connects the left end, which is one end of the upper horizontal frame section 11a and the lower horizontal frame section 11b, in a front view of the sash frame mounting structure 100. The right vertical frame section 12b connects the right end, which is the other end of the upper horizontal frame section 11a and the lower horizontal frame section 11b, in a front view of the sash frame mounting structure 100.

[0047] Furthermore, the frame body 10 of this embodiment further includes a nut portion 13 into which a height adjustment bolt 20a, which serves as a height adjustment body 20, can be screwed. The nut portion 13 of this embodiment may be joined to the lower horizontal frame portion 11b by welding in a position where the central axis of the screw hole in which the female thread portion is formed faces vertically.

[0048] In this embodiment, the frame body 10 enters a first support state when the lower horizontal frame portion 11b is supported by the lower beam 103a, which is part of the structural frame 103, without the use of the height adjustment body 20 (see Figure 1). In contrast, in this embodiment, the frame body 10 enters a second support state when the lower horizontal frame portion 11b is supported by the lower beam 103a, which is part of the structural frame 103, via the height adjustment body 20 (see Figure 2). In this embodiment, the amount of vertical downward protrusion of the height adjustment bolt 20a from the lower horizontal frame portion 11b can be adjusted by changing the screwing state of the height adjustment bolt 20a and the nut portion 13. This allows the first and second support states to be selected according to the state of the structural frame 103.

[0049] As shown in Figures 1 to 3, in this embodiment, multiple height adjustment members 20 are attached to different positions (two in this embodiment) in the frame width direction A of the frame body 10. By attaching multiple height adjustment members 20 to different positions in the frame width direction A of the frame body 10 in this way, it is possible to adjust not only the height position of the entire frame body 10 relative to the structural frame 103, but also the inclination angle of the frame body 10 with respect to the horizontal direction in the in-plane direction of the frame surface of the sash frame 101 attached to the frame body 10 (the same direction as the in-plane direction of the outer wall to which the sash frame 101 is attached). For example, as shown in Figures 2 and 3, the height positions on both sides of the frame width direction A of the frame body 10 are adjusted separately by the two height adjustment members 20. As a result, even a rectangular frame-shaped frame body 10 supported by a lower beam 103a that is inclined with respect to the horizontal can be made to be in a position that is not inclined with respect to the horizontal direction (see Figure 2).

[0050] Next, we will describe a configuration in which multiple frame structures 102, as shown in Figures 1 to 3, are connected in the frame width direction A of the frame body 10. Figures 4 to 6 show a state in which three frame structures 102 are connected in the frame width direction A. Here, we will describe an example in which three frame structures 102 are connected, but the number of connected frame structures 102 is not particularly limited.

[0051] In Figure 4, each of the three frame structures 102 has its frame body 10 supported by the structural frame 103 in the first support state. More specifically, each frame body 10 shown in Figure 4 is supported by the lower beam 103a of the structural frame 103, without the use of height adjustment members 20. The configuration of the lower beam 103a and upper beam 103b shown in Figure 4 is the same as in Figure 1.

[0052] In Figure 5, each of the three frame structures 102 has its frame body 10 supported by the structural frame 103 in the second support state. More specifically, each frame body 10 shown in Figure 5 is supported by the lower beam 103a, which is part of the structural frame 103, via the height adjustment body 20. The configuration of the lower beam 103a and upper beam 103b shown in Figure 5 is the same as in Figure 2. Figure 6 shows the state in which each frame body 10 shown in Figure 5 is supported by the lower beam 103a shown in Figure 5 without the height adjustment body 20. In other words, the three frame bodies 10 of this embodiment are adjusted in height by the height adjustment body 20 from the state shown in Figure 6 to the desired position shown in Figure 5, and then attached to the upper beam 103b.

[0053] The three frame bodies 10 shown in Figure 6 may be sequentially adjusted in height and inclination angle using the height adjustment body 20, starting from the frame body 10 located at one end of the extending direction of the lower beam 103a and upper beam 103b, and moving toward the frame body 10 located at the other end.

[0054] Thus, according to the frame structure 102 of this embodiment, by providing a height adjustment body 20, even when multiple frame bodies 10 are connected in the frame width direction A, the height positions of the multiple frame bodies 10 can be easily aligned.

[0055] For example, to improve the aesthetic appearance, let's consider adopting an interior frame material that extends horizontally across multiple (three in this embodiment) connected frame bodies 10. In this case, if the height positions of the multiple connected frame bodies 10 do not coincide as shown in Figure 6, it may not be possible to install the aforementioned interior frame material so that it extends horizontally across the multiple frame bodies 10. On the other hand, if the height positions of the multiple frame bodies 10 coincide as shown in Figure 5, it becomes easier to install the aforementioned interior frame material so that it extends horizontally across the multiple frame bodies 10. The details of this will be described later (see Figure 7, etc.).

[0056] Next, with reference to Figures 7 and 8, a sash frame mounting structure 300, as a different embodiment from the sash frame mounting structure 100 described above, will be explained. Figure 7 is a horizontal cross-sectional view of the sash frame mounting structure 300. Figure 8 is a vertical cross-sectional view of the sash frame mounting structure 300. The sash frame mounting structure 300 shown in Figures 7 and 8 differs from the sash frame mounting structure 100 described above (see Figures 1 to 6) only in the configuration of the frame body 310; all other configurations are the same.

[0057] First, let's describe the outline of the exterior wall 50 shown in Figures 7 and 8. The exterior wall 50 comprises an exterior wall material 51, an insulating material 52 placed on the indoor side of the exterior wall material 51, and an interior wall material 53 placed on the indoor side of the insulating material 52. The exterior wall material 51 may be an exterior wall panel such as an ALC panel, as described above. The insulating material 52 may be a panel-shaped insulating material made of a foamed resin material such as phenolic foam, polystyrene foam, or urethane foam, as described above. The interior wall material 53 may include, for example, gypsum board.

[0058] As shown in Figures 7 and 8, an opening 51a is formed in the exterior wall material 51. The sash frame 101 is positioned along the periphery of this opening 51a.

[0059] As shown in Figures 7 and 8, the sash frame mounting structure 300 of this embodiment comprises a sash frame 101 and a frame structure 302 comprising the structural frame 103 of the building 200. The sash frame 101 and the structural frame 103 are the same as those of the sash frame mounting structure 100 described above, so their explanation is omitted here.

[0060] The frame structure 302 comprises a frame body 310 and a height adjustment member 20. The height adjustment member 20 is the same as that of the sash frame mounting structure 100 described above, so its description is omitted here.

[0061] The frame body 310 of this embodiment comprises two horizontal frame sections 311, two first vertical frame sections 312, a nut section 313, a leg member 314, and two second vertical frame sections 315.

[0062] As shown in Figure 8, the two horizontal frame sections 311 extend substantially horizontally when the frame body 310 is attached to the structural frame 103. The two horizontal frame sections 311 in this embodiment include an upper horizontal frame section 311a to which the upper frame 101a of the sash frame 101 is attached and which extends along the upper frame 101a, and a lower horizontal frame section 311b to which the lower frame 101b of the sash frame 101 is attached and which extends along the lower frame 101b.

[0063] The upper frame 101a of the sash frame 101 is fixed to the upper horizontal frame portion 311a using fastening members such as screws. As shown in Figure 8, in this embodiment, the upper frame 101a and the upper horizontal frame portion 311a are fixed to the indoor side of the sealing member 54 interposed between the upper frame 101a and the exterior wall material 51 by fastening members such as screws.

[0064] Furthermore, the lower frame 101b of the sash frame 101 is also fixed to the lower horizontal frame portion 311b using fastening members such as screws. As shown in Figure 8, the lower frame 101b and the lower horizontal frame portion 311b in this embodiment are fixed to the indoor side of the sealing member 54 interposed between the lower frame 101b and the exterior wall material 51 by fastening members such as screws.

[0065] As shown in Figure 8, the frame body 310 of this embodiment is attached to the structural frame 103 by having the upper horizontal frame portion 311a attached to the upper beam 103b via mounting brackets 104. The upper horizontal frame portion 311a of this embodiment is configured to allow the attachment of multiple mounting brackets 104 at different positions in its extending direction. However, the attachment positions of the mounting brackets 104 and the number of mounting brackets 104 attached to the upper horizontal frame portion 311a are not particularly limited.

[0066] As shown in Figures 7 and 8, the two first vertical frame sections 312 extend substantially vertically when the frame body 310 is attached to the structural frame 103. The two first vertical frame sections 312 in this embodiment include a first left vertical frame section 312a that extends along the left vertical frame 101c of the sash frame 101, and a first right vertical frame section 312b that extends along the right vertical frame 101d of the sash frame 101.

[0067] The first left vertical frame portion 312a connects the left end, which is one end of the upper horizontal frame portion 311a and the lower horizontal frame portion 311b, in a front view of the sash frame mounting structure 100. The first left vertical frame portion 312a is fixed to the upper horizontal frame portion 311a and the lower horizontal frame portion 311b by fastening members such as screws. However, the first left vertical frame portion 312a may also be joined to the upper horizontal frame portion 311a and the lower horizontal frame portion 311b by welding or the like.

[0068] The first right vertical frame portion 312b connects the right end, which is the other end of the upper horizontal frame portion 311a and the lower horizontal frame portion 311b, in a front view of the sash frame mounting structure 100. The first right vertical frame portion 312b is fixed to the upper horizontal frame portion 311a and the lower horizontal frame portion 311b by fastening members such as screws. However, the first right vertical frame portion 312b may be joined to the upper horizontal frame portion 311a and the lower horizontal frame portion 311b by welding or the like.

[0069] As shown in Figures 7 and 8, the nut portion 313 is configured so that a height adjustment bolt 20a, which serves as the height adjustment body 20, can be screwed into it. In this embodiment, the nut portion 313 is held by a leg member 314 which is fixed to the lower horizontal frame portion 311b by fastening members such as bolts and screws. In this embodiment, the nut portion 313 is joined to the leg member 314 by welding in a position where the central axis of the screw hole in which the female thread portion is formed faces vertically. In this embodiment, the leg member 314 is fixed to the lower horizontal frame portion 311b so as to protrude vertically downward from the lower horizontal frame portion 311b.

[0070] More specifically, the leg member 314 of this embodiment comprises a bottom plate portion 314a extending along the indoor side surface of the lower horizontal frame portion 311b, two side plate portions 314b rising inward from both sides of the frame width direction A of the bottom plate portion 314a, and a retaining plate portion 314c extending horizontally in connection with the bottom plate portion 314a and the two side plate portions 314b, to which a nut portion 313 is attached. A through hole is formed in the retaining plate portion 314c that penetrates vertically. The nut portion 313 is joined to the retaining plate portion 314c by welding, with the through hole in the retaining plate portion 314c communicating with the screw hole in which the female thread portion of the nut portion 313 is formed. However, the nut portion 313 may be fixed to the leg member 314 by fastening members such as screws. Furthermore, the nut portion 313 is not limited to being fixed to the leg member 314 by welding or fastening; for example, it may be a threaded hole formed in the leg member 314 itself.

[0071] As shown in Figure 7, the two second vertical frame sections 315 extend substantially vertically when the frame body 310 is attached to the structural frame 103. The two second vertical frame sections 315 in this embodiment include a second left vertical frame section 315a to which the left vertical frame 101c of the sash frame 101 is attached and which extends along the left vertical frame 101c, and a second right vertical frame section 315b to which the right vertical frame 101d of the sash frame 101 is attached and which extends along the right vertical frame 101d.

[0072] The left vertical frame 101c of the sash frame 101 is fixed to the second left vertical frame portion 315a using fastening members such as screws. As shown in Figure 7, in this embodiment, the left vertical frame 101c and the second left vertical frame portion 315a are fixed by fastening members such as screws on the indoor side of the sealing member 54 interposed between the left vertical frame 101c and the exterior wall material 51.

[0073] Furthermore, the right vertical frame 101d of the sash frame 101 is also fixed to the second right vertical frame portion 315b using fastening members such as screws. As shown in Figure 7, in this embodiment, the right vertical frame 101d and the second right vertical frame portion 315b are fixed to the indoor side of the sealing member 54 interposed between the right vertical frame 101d and the exterior wall material 51 by fastening members such as screws.

[0074] The upper and lower ends of the second left vertical frame section 315a are connected to the left end, which is one end of the upper horizontal frame section 311a and the lower horizontal frame section 311b, in a front view of the sash frame mounting structure 100. The second left vertical frame section 315a and the upper horizontal frame section 311a and the lower horizontal frame section 311b are fixed together by fastening members such as screws. However, the second left vertical frame section 315a and the upper horizontal frame section 311a and the lower horizontal frame section 311b may also be joined together by welding or the like.

[0075] The upper and lower ends of the second right vertical frame section 315b are connected to the right end, which is the other end of the upper horizontal frame section 311a and the lower horizontal frame section 311b, in a front view of the sash frame mounting structure 100. The second right vertical frame section 315b is fixed to the upper horizontal frame section 311a and the lower horizontal frame section 311b by fastening members such as screws. However, the second right vertical frame section 315b may be joined to the upper horizontal frame section 311a and the lower horizontal frame section 311b by welding or the like.

[0076] Thus, the second left vertical frame section 315a and the second right vertical frame section 315b are connected to the upper horizontal frame section 311a and the lower horizontal frame section 311b, similar to the first left vertical frame section 312a and the first right vertical frame section 312b. However, while the second left vertical frame section 315a and the second right vertical frame section 315b extend from the lower surface of the upper horizontal frame section 311a to the upper surface of the lower horizontal frame section 311b, the first left vertical frame section 312a and the first right vertical frame section 312b extend on the indoor side of the upper horizontal frame section 311a and the lower horizontal frame section 311b, from vertically above the upper horizontal frame section 311a to vertically below the lower horizontal frame section 311b. Furthermore, the first left vertical frame section 312a and the second left vertical frame section 315a are not directly connected, and as shown in Figure 7, they are spaced apart in the indoor-outdoor direction B, which is the thickness direction of the outer wall 50. In addition, the first right vertical frame section 312b and the second right vertical frame section 315b are also not directly connected, and as shown in Figure 7, they are spaced apart in the indoor-outdoor direction B.

[0077] The height adjustment bolt 20a, which serves as the height adjustment element 20, is configured to be screwed into the nut portion 313. The height adjustment bolt 20a can change its state between a state in which its tip is retracted above the lower end of the leg member 314 and a state in which its tip protrudes below the lower end of the leg member 314 by changing the state of screwing it into the nut portion 313.

[0078] In this embodiment, the frame body 310 enters a first support state when the lower end of the leg member 314 is supported by the lower beam 103a, which is part of the structural frame 103, without the need for a height adjustment body 20. In other words, in this first support state, the tip of the height adjustment bolt 20a, which is part of the height adjustment body 20, is retracted above the lower end of the leg member 314. Figure 8 shows the frame body 310 in the first support state.

[0079] In contrast, the frame body 310 of this embodiment is supported by the lower beam 103a, which is the structural frame 103, via the height adjustment body 20, thereby achieving a second support state. In other words, in this second support state, the tip of the height adjustment bolt 20a, which is the height adjustment body 20, protrudes below the lower end of the leg member 314.

[0080] Thus, in this embodiment, the amount of vertical downward protrusion of the height adjustment bolt 20a from the lower end of the leg member 314 can be adjusted by changing the screwed state of the height adjustment bolt 20a and the nut portion 313. This allows the first support state and the second support state described above to be selected according to the state of the structural frame 103. Furthermore, in conventional construction, skilled craftsmen measure the installation position and dimensions while installing the sash frames to ensure uniform height, but in this embodiment, the height of the sash frames can be made uniform without measuring dimensions, even by craftsmen who are not skilled.

[0081] Figure 7 shows two frame structures 302 connected in the frame width direction A. The frame body 310 of this embodiment is configured to allow two frame bodies 310 adjacent to each other in the frame width direction A, with their heights substantially aligned. More specifically, as shown in Figure 7, the frame body 310 of this embodiment is provided with a first vertical frame portion 312 extending vertically at the end in the frame width direction A. The first vertical frame portion 312 has a bolt insertion hole 340 that penetrates through the frame width direction A. Two frame bodies 310 adjacent to each other in the frame width direction A, with their heights substantially aligned, are configured to be connected using bolts 341 inserted through the bolt insertion holes 340 of the first vertical frame portion 312. In this way, it is easy to maintain a state in which the heights of multiple frame bodies 310 connected in the frame width direction A are aligned.

[0082] Furthermore, as shown in Figure 7, in the sash frame mounting structure 300 of this embodiment, for the purpose of improving the design, an interior frame material 342 is used that extends horizontally across multiple (two shown in Figure 7) connected frame bodies 310. In this embodiment, such an interior frame material 342 is provided, which is an upper interior frame material 342a connected to the indoor side of the upper frame 101a of the sash frame 101, and a lower interior frame material 342b connected to the indoor side of the lower frame 101b of the sash frame 101. As shown in Figure 7, the lower interior frame material 342b in this embodiment is not configured to be interrupted to match each frame body 310, but is configured to be a single continuous piece that spans multiple (two shown in Figure 7) connected frame bodies 310. Furthermore, in the lower interior frame material 342b, a notch 342b1 is formed at a position corresponding to the adjacent portion of two adjacent frame bodies 310, so as to avoid the first vertical frame portion 312 of the two adjacent frame bodies 310, and the interior cover member 343 which is arranged to cover the indoor side of the first vertical frame portion 312. Similarly, in the upper interior frame material 342a, a notch is formed at a position corresponding to the adjacent portion of two adjacent frame bodies 310.

[0083] If the height positions of the multiple connected frame bodies 310 do not coincide, it may not be possible to install the interior frame material 342 so that it extends horizontally across the multiple frame bodies 310. For example, the first vertical frame portion 312 of two adjacent frame bodies 310 and the interior cover member 343 may not be able to be placed in the notch portion 342b1 of the lower interior frame material 342b. In contrast, by ensuring that the height positions of the multiple frame bodies 310 coincide, it becomes easier to install the interior frame material 342 so that it extends horizontally across the multiple frame bodies 310.

[0084] The frame structure, sash frame mounting structure, and building according to the present invention are not limited to the specific configurations shown in the embodiments described above, and various modifications, changes, and combinations are possible as long as they do not depart from the scope of the claims.
