[0009] [Structure of this embodiment] Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 to 3, the sliding window 1 as a building fixture according to this embodiment is installed in an opening in the building structure to separate the exterior and interior sides, and comprises a window frame 2 (frame body) and an exterior sash 3 (sash) and an interior sash 4 (sash) arranged within the window frame 2. The exterior sash 3 and interior sash 4 are slidable from side to side and are arranged to slide across from each other, with the exterior sash 3 located on the exterior side and the interior sash 4 located on the interior side. Furthermore, the upper frame 31 and lower frame 32 of the exterior sash 3, which will be described later, are each provided with sash stoppers 5 as functional components that limit the sliding range of the exterior sash 3 and interior sash 4, respectively, and the vertical frames 33 and 43 of the exterior sash 3 and interior sash 4, which will be described later, are provided with opening and closing operation components 7 and 8 as functional components that slide the exterior sash 3 and interior sash 4. In the following description, the left-right direction of the sliding window 1 is defined as the X-axis, the up-down direction of the sliding window 1 is defined as the Y-axis, and the depth direction (indoor-outdoor direction) of the sliding window 1 is defined as the Z-axis. The X, Y, and Z axes are mutually orthogonal.

[0010] The window frame 2 is constructed by framing an upper frame 21 and a lower frame 22 along the X-axis direction, and left and right vertical frames 23 along the Y-axis direction. Each frame member 21, 22, 23 is a frame and includes a metal member 24 as an exterior member located on the exterior side and a resin member 25 as an interior member located on the interior side. In this embodiment, the metal member 24 is formed from an aluminum extruded profile, and the resin member 25 is formed from a resin extruded profile. The metal member 24 is constructed to be stronger than the resin member 25, and the resin member 25 has higher thermal insulation properties than the metal member 24.

[0011] The outer sliding door 3 is constructed by assembling an upper frame 31, a lower frame 32, left and right vertical frames 33 and 34, and a facing material 36. The vertical frame 33 constitutes the door edge vertical frame, and the vertical frame 34 constitutes the outer meeting vertical frame. The upper frame 31 and lower frame 32 along the X-axis and the left and right vertical frames 33 and 34 along the Y-axis constitute a frame body 35 assembled on all four sides. A facing material 36 made of glass panels or the like is arranged inside the frame body 35. The interior sliding door 4 is constructed by assembling an upper frame 41, a lower frame 42, left and right vertical frames 43 and 44, and a facing material 46. The vertical frame 43 constitutes the door edge vertical frame, and the vertical frame 44 constitutes the interior meeting vertical frame. The upper frame 41 and lower frame 42 along the X-axis and the left and right vertical frames 43 and 44 along the Y-axis constitute a frame body 45 assembled on all four sides. A facing material 46 made of glass panels or the like is placed inside the frame body 45. Each frame member 31, 41, 32, 42, 33, 43, 34, 44 is a frame and comprises a metal member 11 positioned on the exterior side and a resin member 15 positioned on the interior side. In this embodiment, the metal member 11 is formed from an aluminum extruded profile and constitutes the portion facing the exterior space partitioned by the sliding window 1. The resin member 15 is formed from a resin extruded profile and constitutes the portion facing the interior space partitioned by the sliding window 1. The metal member 11 is constructed to be stronger than the resin member 15, and the resin member 15 has higher thermal insulation properties than the metal member 11.

[0012] The metal member 11 has a hollow frame-shaped metal main body portion 111 and an opening-forming portion 112 formed on the inner circumference side of the metal main body portion 111. The opening-forming portion 112 is composed of a projection portion 113 along the Z-axis direction and an outdoor portion 114 and an indoor portion 115 extending inward in a plane along the X and Y axes. The metal main body portion 111 of the upper frame 31 is provided with a screw hole 117A that forms a space 12A (see Figure 5(A)) between it and the projection portion 113 constituting the opening-forming portion 112, in which the outdoor edge of the first fixing portion 91, described later, is positioned. The metal main body portion 111 of the lower frame 32 is provided with a screw hole 117B that forms a space 12B (see Figure 5(B)) between it and the resin member 15, in which the outdoor edge of the first fixing portion 91 is positioned. The exterior piece 114 and interior piece 115 of the upper frame 31, 41 and the lower frame 32, 42 are aligned along the Y-axis, while the exterior piece 114 and interior piece 115 of the left and right vertical frame 33, 34, 43, 44 are aligned along the X-axis. This opening forming portion 112 forms an opening 112A that holds the peripheral edges of the facing material 36, 46. In addition, an extended piece 116 extending outward is formed in the continuous portion of the projection piece 113 and the interior piece 115, and this extended piece 116 has a notch 116A that is cut out so that the first fixing portion 91, which will be described later, can be inserted.

[0013] The resin members 15 in the upper frames 31, 41, lower frames 32, 42, and vertical frames 33, 43, 44 are formed in a hollow shape, covering at least the opening forming portion 112 from the interior side. In this resin member 15, a hollow rectangular interior facing portion 151 is provided in the portion facing the opening forming portion 112 in the Z-axis direction. The interior facing portion 151 is formed by continuously extending the inner and outer ends of the interior and exterior facing pieces 152, 153. The interior facing pieces 152, 153 of the upper frame 31 and lower frame 32 of the outer sash 3 have notches 152A, 153A into which the fixing members 9A, 9B, described later, can be inserted from the interior side in the Z-axis direction. The interior side notch 152A is covered from the interior side by the sash stopper 5. The resin member 15 in the vertical frame 34 that constitutes the outer call frame is composed of a resin cover material that covers the metal member 11 at a position facing the indoor space in the closed state of the sliding window 1.

[0014] As shown in FIGS. 1, 4, 6, and 7, the shoji stopper 5 is arranged along the indoor finding surface 15A of the resin member 15 of the upper frame 31 and the lower frame 32 of the outer shoji 3, and has a base portion 51 that covers the notch portion 152A from the indoor side, and a stopper portion 52 having an abutting portion 52A that is attached to the base portion 51 and abuts against the vertical frame 44 that constitutes the inner call of the inner shoji 4 (other shoji) in the X-axis direction on the inner side in the X-axis direction. The base portion 51 is fixed to a second fixing portion 95 described later via a screw 62 described later as a fixing tool. The base portion 51 extends along the X-axis direction (longitudinal direction) of the upper frame 31 and the lower frame 32 and is configured to be thick in the Z-axis direction. The stopper portion 52 is provided with the abutting portion 52A at an inner position in the X-axis direction. The abutting portion 52A extends in the Z-axis direction and is configured to be thick in the X-axis direction of the upper frame 31 and the lower frame 32. Therefore, while the strength of the base portion 51 in the X-axis direction fixed to the second fixing portion 95 can be improved, the strength of the abutting portion 52A in the Z-axis direction against which the vertical frame 44 of the inner shoji 4 abuts can be improved. Also, by forming the base portion 51 thick, the risk of cracking or the like due to the base portion 51 being bitten into the screw 62 by the force applied when the shoji stopper 5 receives the vertical frame 44 of the inner shoji 4 can be reduced. Note that FIG. 4(A) is a developed perspective view showing the upper frame 31 and the shoji stopper 5, FIG. 4(B) is a developed perspective view showing the lower frame 32 and the shoji stopper 5, FIG. 5(A) is a longitudinal sectional view showing the upper frame 31 and the shoji stopper 5 developed, and FIG. 5(B) is a longitudinal sectional view showing the lower frame 32 and the shoji stopper 5 developed.

[0015] Here, a fixing member 9A is fixed to the upper frame 31, and as shown in (B) of FIG. 5, a fixing member 9B is fixed to the lower frame 32. Further, a shoji stopper 5 is fixed to the fixing members 9A and 9B. The fixing members 9A and 9B are made of metal, and for example, they may be made of steel, stainless steel, or aluminum, as long as they are materials and configurations that can exhibit sufficient strength to firmly fix the shoji stopper 5.

[0016] As shown in (A) of FIG. 8, the fixing member 9A has a first fixing portion 91 along the Z-axis direction and a second fixing portion 95 along the Y-axis direction as the finding direction of the upper frame 31 and the lower frame 32. The first fixing portion 91 and the second fixing portion 95 are each formed in a flat plate shape, and the fixing member 9A composed of the first fixing portion 91 and the second fixing portion 95 is configured in a substantially L-shaped cross-section. The first fixing portion 91 has a protruding portion 92 protruding on one side in the X-axis direction (the longitudinal direction of the upper frame 31), and in this embodiment, protruding inward in the X-axis direction (inside the longitudinal direction of the upper frame 31). The protruding portion 92 protrudes inward in the X-axis direction from the second fixing portion 95. Further, three fixing holes 911, 912, and 913 are formed in the first fixing portion 91. The hole 911 is disposed at a position covering the main body portion of the first fixing portion 91 and the portion of the protruding portion 92. The hole 913 is disposed at the outer portion of the first fixing portion 91 in the X-axis direction. In the first fixing portion 91, the hole 912 is disposed at a portion between the holes 911 and 913. The holes 911, 912, and 913 are screwed to the expected piece portion 113 constituting the opening forming portion 112 by screws 61A, 61B, and 61C. The screw 61A is a first fixture, the screw 61B is a second fixture, and the screw 61C is a third fixture, and these are arranged side by side in the X-axis direction. The screws 61A, 61B, and 61C may be water-stop screws having a seal portion formed on the seating surface. Further, a pressing piece portion 914 bent downward from the outer edge portion of the first fixing portion 91 in the X-axis direction is formed in the first fixing portion 91, and the pressing piece portion 914 is disposed at a position where the second fixing portion 95 can be pressed from the first fixing portion 91 side. The second fixing portion 95 is bent downward from the first fixing portion 91, is smaller than the notch 152A, and is configured to be positioned within the notch 152A. The second fixing portion 95 also has two fixing holes 951 and 952 that face each other in the X-axis direction. The holes 951 and 952 are screwed to the shoji stopper 5 by screws 62 (fixing devices).

[0017] As shown in Figure 8(B), the fixing member 9B is configured in substantially the same way as the fixing member 9A. Therefore, the components of the fixing member 9B are denoted by the same reference numerals as those of the fixing member 9A, and their detailed descriptions are omitted. In the fixing member 9B, the second fixing portion 95 is bent upward relative to the first fixing portion 91, and the retaining piece portion 914 of the first fixing portion 91 is also bent upward.

[0018] As shown in Figure 10(A), on the lower frame 32 side, the first fixing portion 91 is fixed to the lower frame 32 from the inside of the opening of the opening forming portion 112 by a screw 61A, which is a first fixing device positioned outward in the X-axis direction, and a screw 61B, which is a second fixing device positioned inward in the X-axis direction. Here, the lower frame 32 has the aforementioned screw hole 117B, which is an outdoor-facing portion that faces the outdoor side of the screws 61A, 61B and the screw 61C, which is a third fixing device, and is positioned to be able to abut against the screw 61A, and the aforementioned contact piece portion 116B, which is an indoor-facing portion that faces the indoor side of the screws 61A, 61B, and 61C, and is positioned to be able to abut against the screw 61B. Therefore, when the shoji stopper 5 receives the inner shoji 4 that abuts against the contact portion 52A, a rotational moment toward the outside is generated on the screw 61A side and a rotational moment toward the inside is generated on the screw 61B side. However, since screw 61A abuts against the screw hole 117B and screw 61B abuts against the contact piece portion 116B, screws 61A and 61B can be received, and at least the risk of the screw 61A and the first screw 61B being pulled out can be reduced. Furthermore, the shoji stopper 5 is fixed to the second fixing portion 95 by a screw 62 as a fixing device, and between screws 61A and 61B, there is a screw 61C as a third fixing device that fixes screw 61A to the lower frame 32 from the opening 112A side of the opening forming portion 112. Screw 61C is located closer to screw 61B than screw 61A in the X-axis direction, and is positioned opposite the inner screw 62 in the Z-axis direction in the X-axis direction. By positioning screw 61C closer to screw 61B in this manner, the fixing strength of screw 61B can be reinforced. Furthermore, by positioning screw 61C opposite screw 62 in the Z-axis direction, screws 61C and 62 can be placed on the same line extending in the Z-axis direction, thereby suppressing the rotation of the sliding door stopper 5 due to the rotational moment and reducing the risk of screws 61A, 61B, and 61C being pulled out due to such rotation.

[0019] [Securing the shoji screen stopper 5 to the upper frame 31] The aforementioned shoji stopper 5 is fixed to the upper frame 31 in the following manner. First, as shown in Figure 9(B), the fixing member 9A is inserted into the notches 152A, 153A, and 116A from the indoor side. At this time, the fixing member 9A is rotated in the R direction so that the protruding portion 92 does not catch on the periphery of the notches 152A, 153A, and 116A. In the inserted state with the fixing member 9A inserted into the upper frame 31, as shown in Figure 6, the first fixing part 91 is positioned on the outside of the opening relative to the visible piece 113 of the opening forming part 112, the outdoor edge of the first fixing part 91 is positioned in the space 12A and sandwiched between the visible piece 113 and the screw hole 117A, the protruding part 92 is positioned opposite the extended piece 116 of the metal member 11 from the outdoor side in the Z-axis direction (see Figure 9(A)), the indoor surface of the second fixing part 95 is positioned along the indoor visible surface 15A of the resin member 15, and the outdoor surface of the base 51 of the sash stopper 5 is positioned flush with the indoor visible surface 15A. Figure 9(A) shows the upper frame 31 and the fixing member 9A from the opening 112A side of the upper frame 31, and Figure 9(B) shows the assembly of the fixing member 9A to the upper frame 31 from the opening 112A side of the upper frame 31. Next, as shown in Figures 6 and 9(A), screws 61A, 61B, and 61C are passed through the projection piece 113 of the opening forming part 112 from the opening 112A side (downward side) and screwed into the holes 911, 912, and 913 of the first fixing part 91, thereby fixing the first fixing part 91 along the projection piece 113. Finally, as shown in Figure 6, the base 51 of the shoji stopper 5 is fixed to the second fixing part 95 with a screw 62. This fixing fixes the shoji stopper 5 to a predetermined position on the upper frame 31 via the fixing member 9A. In this fixed state, the notch 152A is covered from the interior side by the shoji stopper 5, and the first fixing part 91 and the second fixing part 95 are positioned to cover a portion of the visible piece 113 and the interior piece 115 of the opening forming part 112. In this way, the sliding window 1 has a fixing structure for the sash stopper 5 to the upper frame 31. The shoji screen stopper 5 may also be fixed to the second fixing part 95 first.

[0020] [Securing the shoji screen stopper 5 to the lower frame 32] The aforementioned shoji stopper 5 is fixed to the lower frame 32 in the following manner. First, as shown in Figure 10(B), the fixing member 9B is inserted into the notches 152A, 153A, and 116A from the indoor side. At this time, the fixing member 9B is rotated in the R direction so that the protruding portion 92 does not catch on the periphery of the notches 152A, 153A, and 116A. In the inserted state with the fixing member 9B inserted into the lower frame 32, as shown in Figure 7, the first fixing part 91 is positioned on the outside of the opening relative to the visible piece 113 of the opening forming part 112, the outdoor edge of the first fixing part 91 is positioned in space 12B and sandwiched between the visible piece 113 and the screw hole 117B, the protruding part 92 is positioned opposite the extended piece 116 of the metal member 11 from the outdoor side in the Z-axis direction (see Figure 10(A)), the indoor surface of the second fixing part 95 is positioned along the indoor visible surface 15A of the resin member 15, and the outdoor surface of the base 51 of the sash stopper 5 is positioned flush with the indoor visible surface 15A. The extended piece 116 of the lower frame 32 has a contact piece 116B that extends in the Z-axis direction toward the outdoor side. Figure 10(A) shows the lower frame 32 and the fixing member 9B from the opening 112A side of the lower frame 32, and Figure 10(B) shows the assembly of the fixing member 9B to the lower frame 32 from the opening 112A side of the lower frame 32. Next, as shown in Figures 7 and 10(A), screws 61A, 61B, and 61C are passed through the projection piece 113 of the opening forming part 112 from the opening 112A side (upper side) and screwed into the holes 911, 912, and 913 of the first fixing part 91, thereby fixing the first fixing part 91 along the projection piece 113. Finally, the shoji stopper 5 is fixed to the second fixing part 95 with screws 62. This fixing fixes the shoji stopper 5 to a predetermined position on the lower frame 32 via the fixing member 9B. In this fixed state, the notch 152A is covered from the interior side by the shoji stopper 5, and the first fixing part 91 and the second fixing part 95 are positioned to cover a portion of the visible piece 113 and the interior piece 115 of the opening forming part 112. In this way, the sliding window 1 has a fixing structure for the sash stopper 5 to the lower frame 32. The shoji screen stopper 5 may also be fixed to the second fixing part 95 first.

[0021] With the sliding window 1 described above, for example, it is not necessary to form a substantially C-shaped engaging portion in the metal member 11 on the upper frame 31 and lower frame 32 in order to fix the fixing members 9A and 9B to the upper frame 31 and lower frame 32, thereby improving condensation prevention by reducing the amount of metal parts. Since the second fixing portion 95 is positioned along the interior-facing surface 15A of the resin member 15, the shoji stopper 5 fixed to the second fixing portion 95 can be easily positioned flush with the interior-facing surface 15A, thereby improving the appearance and design. Since there is no need to place spacers or the like between the shoji stopper 5 and the fixing members 9A and 9B to adjust the expected position of the shoji stopper 5, the number of such spacers and other parts can be reduced. By fixing the first fixing part 91 from the opening 112A side formed by the opening forming part 112, the fixing members 9A and 9B are fixed to the metal member 11, eliminating the need to use an insertion jig or the like for fixing, thereby improving the workability of fixing. Even when the metal member 11 and the resin member 15 are combined, the fixing members 9A and 9B can be inserted through the notch 152A, etc., and the fixing work for securing the shoji stopper 5 can be performed. Furthermore, as described above, since the fixing work can be performed, the positioning of the fixing members 9A and 9B can be easily performed compared to, for example, when the fixing work for the shoji stopper 5 is performed with the metal member 11 and the resin member 15 separated. Since the shoji stopper 5 can be directly fixed to the fixing members 9A and 9B without going through the visible portion of the resin member 15, there is no risk of screws 62 or other fasteners digging into the visible portion of the resin member 15 due to repeated sliding movements of the outer shoji 3 and inner shoji 4, and the shape of the upper frame 31 and lower frame 32 can be maintained appropriately. Even if force is applied to the shoji screen stopper 5 to limit the sliding range of the outer shoji screen 3 or inner shoji screen 4 in the X-axis direction, the protruding portion 92 can engage with the extended piece 116 of the metal member 11, thereby improving the fixing strength of the shoji screen stopper 5. Since the pressing piece 914 of the first fixing part 91 is positioned to press the second fixing part 95 from the outside, even if the aforementioned force is applied to the shoji stopper 5, the predetermined fixed state of the shoji stopper 5 can be firmly maintained. Since the fixing members 9A and 9B have a first fixing portion 91 and a second fixing portion 95 and are formed in a substantially L-shape in cross-section, the first fixing portion 91 can be easily positioned along the visible piece portion 113 of the opening forming portion 112, and the second fixing portion 95 can be easily positioned along the interior facing surface 15A of the resin member 15. Before placing the peripheral edge of the facing material 36 into the opening 112A, the fixing members 9A and 9B can be easily secured with screws 61A, 61B, and 61C, thereby improving workability.

[0022] [Differentiation] In the above embodiment, the first fixing portion 91 has a protrusion 92, but it is not limited to this, and the configuration of the protrusion 92 may be omitted if the shoji stopper 5 can be fixed with sufficient strength even without the protrusion 92. In the above embodiment, the first fixing part 91 is arranged along the Z-axis direction, and the second fixing part 95 is formed along the visible direction (Y-axis direction in the case of the upper frame 31 and lower frame 32). However, the embodiment is not limited to this, and the first fixing part 91 and the second fixing part 95 may be arranged at an inclination with respect to the Z-axis direction and the visible direction. In the above embodiment, if higher strength is required for the fixing members 9A and 9B, the mutual separation of the first fixing part 91 and the second fixing part 95 can be suppressed by welding a separate part, such as a rib, to both the first fixing part 91 and the second fixing part 95, thereby further improving the strength of the fixing members 9A and 9B. In the above embodiment, the fixing members 9A and 9B are provided with a retaining piece 914, but the invention is not limited to this, and if sufficient strength can be achieved without the retaining piece 914, the configuration of the retaining piece 914 may be omitted. In the above embodiment, the fixing members 9A and 9B are fixed to the upper frame 31 and lower frame 32 with three screws 61A, 61B, and 61C, but the invention is not limited to this, and they may be fixed to the upper frame 31 and lower frame 32 with one or four or more screws. In the above embodiment, the base 51 and contact portion 52A of the shoji stopper 5 are made thick, but the invention is not limited to this, and if the shoji stopper 5 has sufficient strength, the base 51 and contact portion 52A may be made of normal thickness instead of thick. In the above embodiment, the exterior members are made of metal members 11 and 24, and the interior members are made of resin members 15 and 25. However, the embodiment is not limited to this, and the exterior members may be made of other materials as long as they are made of a material that has higher strength than the interior members, and the interior members may be made of other materials as long as they have higher thermal insulation properties than the exterior members. For example, the exterior members may be made of steel instead of aluminum, and the interior members may be made of wood instead of resin. In the above embodiment, the shoji stopper 5 is provided on both the upper frame 31 and the lower frame 32. However, the invention is not limited to this, and the shoji stopper 5 may be provided on only one of the upper frame 31 or the lower frame 32, as long as the sliding movement of the outer shoji 3 or inner shoji 4 can be restricted to a limited range. Furthermore, the shoji stopper 5 may be fixed to a metal member 24 such as the vertical frame 23 of the window frame 2 via a fixing member configured in substantially the same manner as the fixing members 9A and 9B. The opening and closing operation parts 7 and 8 in the above embodiment may be fixed to the vertical frames 33 and 43 using the aforementioned fixing members 9A and 9B. In this case, the second fixing part 95 is positioned to extend toward the meeting side relative to the first fixing part 91, and notches for inserting the fixing members 9A and 9B are appropriately formed in the metal member 11 and resin member 15 of the vertical frames 33 and 43. Furthermore, the configuration of the opening and closing operation parts 7 and 8 may be omitted. In the above embodiment, a finger-pinch prevention stopper (not shown) that prevents collision with the vertical frame 23, such as the vertical stile 44 (internal meeting stile), may be attached to the window frame 2 as a functional component. In this case, the finger-pinch prevention stopper may be fixed using fixing members 9A and 9B. In the above embodiment, a sliding window 1 was described as the joinery, but other sliding windows such as single-hung windows may also be used as joinery.

[0023] [Summary of the invention] (1) The joinery of the present invention comprises a frame and a sliding screen disposed within the frame, wherein the sliding screen comprises a frame and a facing material disposed within the frame, the frame and the frame each comprises a frame, at least one of the frames of the frame and the frame comprises an exterior member disposed on the exterior side of the frame and an interior member disposed on the interior side of the frame, the exterior member is constructed to be stronger than the interior member and the interior member is front The exterior member is constructed to have higher thermal insulation properties than the exterior member, the exterior member forms an opening-forming portion for holding the surface material, and in one of the frames, a functional component arranged on the interior surface of the interior member is fixed to the exterior member via a fixing member, the fixing member comprising a first fixing portion fixed to the exterior member and a second fixing portion fixed to the functional component, the first fixing portion being fixed at a position outside the opening relative to the opening-forming portion, and the second fixing portion being arranged along the interior surface of the interior member. According to the building fittings of the present invention, since the first fixing portion of the fixing member is fixed to the opening forming portion of the exterior member at a position outside the opening, it is not necessary to form a substantially C-shaped engaging portion in the exterior member for holding back plates and the like that which fix functional components, and the portion of the frame that is made up of exterior members can be reduced, thereby improving condensation prevention. Furthermore, since the second fixing portion is positioned along the interior-facing surface of the interior component, functional components fixed to the second fixing portion can be easily positioned along the interior-facing surface, thereby improving the appearance and design. Furthermore, since there is no need to place spacers or the like between the functional component and the fixing member to adjust the expected position of the functional component, the number of such spacers and other parts can be reduced. In addition, for example, when forming an engagement portion with a roughly C-shaped cross-section along the longitudinal direction of the exterior member and inserting a backing plate into this engagement portion in the longitudinal direction, it becomes necessary to use a jig for inserting the backing plate. However, with the building fittings of the present invention, it is not necessary to use the aforementioned insertion jig when fixing the fixing member to the exterior member, thus improving the workability of fixing. (2) The joinery of the present invention may include a metal member as the exterior member and a resin member as the interior member. With this configuration, it is possible to construct a building component, such as a typical metal-resin composite window, which is made by combining metal parts and resin parts, and which can exhibit the effects and advantages of the present invention described above. (3) In the building fittings of the present invention, the interior member may have a notch formed therein in which the fixing member is placed. With this configuration, even when the exterior and interior components are combined, the fixing member can be inserted through the notch, allowing for the fixing of functional components. Furthermore, as mentioned above, since the fixing work can be performed, the positioning of the fixing member can be easily done compared to, for example, when fixing functional components with the exterior and interior components separated. Furthermore, since the functional components can be directly fixed to the fixing member without going through the visible portion of the interior member, there is no risk of the fasteners used to fix the functional components to the fixing member digging into the visible portion of the interior member based on the force applied to the functional components, and the shape of the frame can be maintained appropriately. (4) In the building fitting of the present invention, the fixing member may have a protruding portion that faces the exterior member in the depth direction. This configuration allows for improved fixing strength of functional components by the fixing members. (5) In the joinery of the present invention, the opening forming portion is configured to have a depth portion along the depth direction and an exterior portion and an interior portion along the face direction perpendicular to the depth direction, the first fixing portion may be arranged along the depth direction, and the second fixing portion may be arranged along the face direction. With this configuration, the first fixing part can be easily positioned along the visible portion of the opening forming part, and the second fixing part can be easily positioned along the interior facing surface of the interior member, making it easy to position and fix the fixing members. (6) In the joinery of the present invention, the first fixing portion may be fixed from the inside of the opening of the opening forming portion by a fixing device. With this configuration, the fixing member can be easily secured with a fixing device before placing the facing material in the opening formed in the opening-forming section, thereby improving workability. (7) In the joinery of the present invention, the frame body comprises an upper frame, a lower frame, and left and right vertical frames as the frame, and the functional component may consist of a shoji stopper fixed to at least one of the upper frame and the lower frame via the fixing member. With this configuration, the shoji screen stopper can be fixed in place as described above. (8) In the joinery of the present invention, at least one of the upper frame and the lower frame is at least the lower frame, the shoji stopper has a contact portion on the inside in the longitudinal direction of the lower frame against which the other shoji will abut, the first fixing portion is fixed to the lower frame from the inside of the opening of the opening forming portion by a first fixing device arranged on the outside in the longitudinal direction of the lower frame and a second fixing device arranged on the inside in the longitudinal direction of the lower frame, the lower frame may have an outdoor facing portion that faces the outdoor side of the first fixing device and is arranged to abut against the first fixing device, and an indoor facing portion that faces the indoor side of the second fixing device and is arranged to abut against the second fixing device. With this configuration, when the shoji stopper receives another shoji screen that is in contact with the contact point, a rotational moment toward the outside is generated on the first fixing device side and a rotational moment toward the inside is generated on the second fixing device side. However, since the first fixing device comes into contact with the opposite part on the outside and the second fixing device comes into contact with the opposite part on the inside, the first and second fixing devices can be received, thereby reducing the risk of the first and second fixing devices being pulled out. (9) In the joinery of the present invention, the shoji stopper is fixed to the second fixing part by a fastener, and between the first fastener and the second fastener, there is further a third fastener that fixes the first fixing part to the lower frame from the opening side of the opening forming part, and the third fastener may be positioned closer to the second fastener than the first fastener and in a position opposite to the fastener in the depth direction. With this configuration, by positioning the third fastener closer to the second fastener, the fixing strength of the second fastener can be reinforced. Furthermore, by positioning the third fastener opposite the first fastener in the depth direction, the third fastener and the first fastener can be positioned on the same line extending in the depth direction, thereby suppressing the rotation of the shoji stopper due to the rotational moment and reducing the risk of the first, second, and third fasteners being pulled out due to such rotation. (10) In the joinery of the present invention, the shoji stopper has a base that is fixed to the second fixing part and a stopper part that has a contact part that contacts another shoji, the base part may extend along the longitudinal direction of at least one of the upper frame and the lower frame and be thickened in the depth direction, and the contact part may extend in the depth direction and be thickened in the longitudinal direction of at least one of the upper frame and the lower frame. With this configuration, the strength of the base fixed to the second fixing part in the longitudinal direction can be improved, while the strength of the contact part that abuts against other shoji screens in the depth direction can be improved. Furthermore, by forming the base with a thicker wall, the risk of cracking or other damage caused by the base biting into the fastener due to the force applied when the shoji stopper receives another shoji screen can be reduced. (11) In the joinery of the present invention, the frame body comprises an upper frame, a lower frame, and left and right vertical frames as the frame, and the functional component may consist of an opening and closing operation component fixed to one of the left and right vertical frames via the fixing member. With this configuration, the opening and closing mechanism can be fixed in place as described above. [Explanation of Symbols]
