However, in the shoji used for the fittings described above, the building material base portion is arranged up to the very vicinity of the interior side of the room. For this reason, the outdoor temperature is transmitted to the very vicinity of the indoor space by the base of the building material, and there is still room for improvement in terms of heat insulation.

On the other hand, fittings made entirely of resin are also provided. Such fittings are advantageous in terms of heat insulation compared to the fittings described in Patent Document 1. However, in terms of weather resistance, resin is inferior to metal, so surface deterioration such as discoloration and cracking may occur early. In addition, considering the coefficient of thermal expansion of resin, resin is larger than that of metal, so if the temperature rises due to direct sunlight irradiation, there is a possibility that the building material for the stile will be deformed.

The projection dimension of the complementary frame surface member support portion 13b is substantially equal to the projection dimension of the complementary frame support piece portion 12c provided on the upper frame outer component portion 12A.

As shown in FIG. 6(a), the common complementary frame-constituting portion 13A has only the above-described common configuration. On the other hand, as shown in FIG. 6B, the upper complementary frame-constituting portion 13B has a restricting piece portion 13d in addition to the above-described common construction. The restricting piece portion 13d protrudes inwardly from the edge portion on the outside of the room on the inner peripheral surface of the auxiliary frame base portion 13a. Between the regulating piece 13d and the complementary frame surface member supporting portion 13b, a gap is secured that is wide enough to accommodate the complementary frame supporting piece 12c of the upper frame outer component portion 12A. The projecting dimension of the restricting piece portion 13d is substantially equal to the projecting dimension of the auxiliary frame surface material support portion 13b.

The common complementary frame-constituting portion 13A and the upper complementary frame-constituting portion 13B described above are formed in a rectangular shape by connecting the ends thereof. By press-fitting the periphery of the insect screen 4 together with the pressing rubber 4a into each of the supplementary frame component parts 13A and 13B connected in a rectangular shape, the auxiliary frame component parts 5 for insect control can be obtained. will be constructed. The complementary frame-constituting portion 13 connected in a rectangular shape is configured so that the rectangular cylindrical portion formed by the inner peripheral cover plate portion 12a4 can be inserted when the end portions of the frame outer-constituting portion 12 are connected to each other. dimensions are set.

In order to configure the frame body 1 with the frame inner component 11, the frame outer component 12, and the auxiliary frame component 13 configured as described above, the frame abutting portions are prepared in advance as shown in FIG. 7(a). A connecting auxiliary piece 16 is attached to 11b. The connecting auxiliary piece 16 is made of resin, similarly to the frame inner component 11, and has a prospective attachment piece portion 16a, an additional attachment piece portion 16b, and an inclined surface portion 16c. The prospective mounting piece portion 16a has a flat plate shape extending along the prospective direction. The attachment piece portion 16b has a flat plate shape extending in the attachment direction from the edge of the attachment piece portion 16a on the exterior side toward the inner peripheral side. The inclined surface portion 16c is gradually inclined toward the interior side from the inner peripheral edge portion of the mounting piece portion 16b toward the inner periphery. The angle of inclination of the inclined surface portion 16c with respect to the attachment piece portion 16b is substantially the same as the angle of inclination of the inclined extension portion 12d1 with respect to the cover plate portion 12a1 provided on the frame outer component portion 12. As shown in FIG. The connecting auxiliary piece 16 is attached to the frame inner forming portion 11 by screwing a screw 16d into the inner peripheral surface of the frame abutment portion 11b via the prospective attachment piece portion 16a. At this time, the attachment position is set so that the attachment piece portion 16b protrudes to the outdoor side from the attachment surface 11m, which is the outdoor side of the frame inner component portion 11. As shown in FIG. The projection dimension of the finding attachment piece 16b from the frame inner component 11 is substantially equal to the projection dimension of the positioning rib 12a7 provided on the frame outer component 12. As shown in FIG. Although not shown in the drawing, the auxiliary connection piece 16 may be provided continuously over the entire length of the frame contact portion 11b, or may be provided at a plurality of locations on the frame contact portion 11b. good.

After that, as shown in FIG. 4, 45° inclined joint surfaces 11X are formed at both ends of the frame inner constituent portion 11, and the ends of the frame inner constituent portion 11 are connected to each other via the inclined joint surfaces 11X. Connect by welding. From this state, after mounting the corresponding frame outer forming portions 12 to the respective frame inner forming portions 11, the ends of the frame outer forming portions 12 are connected to each other. More specifically, the upper frame outer forming portion 12A is arranged between the upper end portions of the left and right vertical frame outer forming portions 12C, and the lower frame outer forming portion 12B is arranged between the lower end portions of the left and right vertical frame outer forming portions 12C. The end portions of the frame outer constituent portion 12 are connected by screwing screws into the screw holes 12b of the vertical frame outer constituent portion 12C through the outwardly extending portions of the vertical frame outer constituent portion 12C. become.

As shown in FIG. 1, when attaching the lower frame outer forming portion 12B to the frame inner forming portion 11, the outer waterproofing is carried out in advance along the positioning rib 12a7 on the inner peripheral side of the lower frame outer forming portion 12B. A material (water stop material) 17 is arranged, and an inner water stop material (water stop material) 18 is arranged on the outer peripheral cover plate portion 12a5.

When the frame outer component 12 is attached to the frame inner component 11, the outer peripheral cover plate portion 12a5 is in contact with the engaging protrusion 11d, and the engaging piece 12a8 is in contact with the indoor side of the engaging protrusion 11d. The positioning ribs 12a7 of the attachment cover plate portion 12a1 are in contact with the attachment surface 11m of the frame inner component portion 11, which is the outdoor side. That is, the engaging protrusion 11d of the frame inner component 11 is fitted between the positioning rib 12a7 and the engaging piece 12a8. In addition, the inclined extension portion 12d1 of the frame outer component portion 12 is in contact with the inclined surface portion 16c. Therefore, when the connecting screw 19 is screwed into the fitting cover plate portion 12a1 from the indoor side via the mounting piece portion 16b in this state, the frame inner component portion 11 and the frame outer component portion 12 are connected to each other. As a result, between the lower frame outer component portion 12B and the frame inner component portion 11 described above, the outer water stop material 17 is positioned between the cover plate portion 12a1 and the outer surface 11m of the frame inner component portion 11 on the outdoor side. and is interposed in a pressed state. Furthermore, since the inclined extension portion 12d1 and the inclined surface portion 16c are pressed against each other by the screwing of the connecting screw 19, the frame inner component portion 11 moves toward the outer peripheral side relative to the frame outer component portion 12 due to the inclination. . As a result, the frame seal member 15 arranged on the engaging projection 11d is pressed against the outer peripheral cover plate portion 12a5, and the inner water stop material 18 arranged on the outer peripheral cover plate portion 12a5 is pushed outside the frame inner component portion 11. It is pressed against the peripheral surface 11f.

With respect to the frame outer component 12 and the frame inner component 11 which are connected to each other on all four sides, if the inner peripheral cover plate portion 12a4 is covered with the insect-proof auxiliary surface material 5, the insect-proof auxiliary surface material 5 is attached to the frame outer component. The frame 1 in a state of being supported by 12 is constructed. In this frame 1, the opening is covered with the insect screen 4, preventing foreign matter from entering the room through the opening. As is clear from FIG. 3, the auxiliary insect-proof surface material 5 is disposed between the restricting piece 13d provided in the upper supplementary frame-constituting portion 13B and the supplementary frame surface material supporting portion 13b of the upper frame outer constituting portion 12A. Since the complementary frame support piece portion 12c is arranged, it does not fall out of the frame outer component portion 12 inadvertently. In order to attach the frame 1 to the frame B, the frame support projection 12e and the auxiliary frame support projection 12f of the lower frame outer component 12B are brought into contact with the frame B, and the frame support 11c of the frame inner component 11 is attached. is brought into contact with the frame B, and from this state, the screws S are screwed into the frame B through the frame mounting plate portions 12a6 provided on the four peripheral frame outer component portions 12. As shown in FIG.

Here, as shown in FIGS. Between the frame building material 10 and the frame building material 20, the secondary sealing member 23 of the frame main body 21 abuts on the facing surface 11k of the frame inner forming portion 11, which is the interior side, and the primary sealing member 14 contacts the frame. It is set so as to abut against a facing surface 21k on the outdoor side of the main body 21. As shown in FIG. Therefore, if the shoji 2 is supported by the frame 1 so as to be openable and closable while maintaining this state, when the shoji 2 is closed with respect to the frame 1, the primary sealing member 14 and the secondary sealing member are formed on the four circumferences. 23 are interposed between the frame 1 and the shoji 2 at the same time, so that fittings ensuring desired airtightness and water stoppage can be configured.

In addition, with respect to the frame building material 20 that constitutes the shoji 2, both the frame body 21 and the rim 22 are molded from resin, and with respect to the frame building material 10 that constitutes the frame body 1, the inside of the frame is molded from resin. The constituent part 11 occupies a region beyond the shoji 2 to a part on the outdoor side. In addition, the outer peripheral cover plate portion 12a5 of the frame outer component portion 12 made of metal terminates on the outdoor side in the perspective direction from the glass plate 3a1, which is arranged on the furthest outdoor side of the panel 3 of the shoji 2. Therefore, according to this fitting, the range affected by the temperature on the outdoor side is limited to the portion arranged on the outdoor side of the shoji 2, which is advantageous in terms of heat insulation. As a result, for example, even when the outdoor temperature is low, dew condensation is less likely to occur on the portions of the frame 1 and the shoji 2 that are exposed to the indoor side.

Moreover, in this fitting, the position of the inner peripheral cover plate portion 12a4, which is the innermost peripheral side of the frame outer forming portion 12, is the expected surface (inner peripheral side) of the face material support portion 21b on all four circumferences. It is set so as to match the prospective direction with respect to the position of 21m. For this reason, the face material supporting portion 21b located on the outdoor side of the frame body 21 of the shoji 2 relative to the face material 3 is difficult to be visually recognized from the outdoor side along the viewing direction. In other words, when the fittings are viewed from the outdoor side, all visible parts are made of metal. Therefore, according to this fitting, it is possible to prevent direct sunlight from irradiating the face material supporting portion 21b of the frame body 21, and problems such as surface deterioration and thermal deformation are less likely to occur, which is advantageous in terms of weather resistance. Become.

By the way, from the above-mentioned viewpoint of heat insulation, since the dimension along the projection direction of the frame inner component 11 is configured to be larger than that of the frame outer component 12, the mutual joint portion is located on the outdoor side. , there is a concern that outdoor water, such as rainwater, may enter between each other. However, in this fitting, between the frame inner component 11 and the frame outer component 12, the outer water stop material 17, the frame seal member 15, and the inner water stop material 18 are arranged from the outdoor side. be. Therefore, there is no possibility that outdoor water will enter the room through the joint between the frame inner component 11 and the frame outer component 12 .

In the fittings described above, since the ends of the frame outer component 12 having the frame mounting plate portion 12a6 that is attached to the frame B are connected by flat joints, the frame outer component 12 is , the cross-sectional shapes of adjacent ones do not have to match. As a result, for example, even if the shape of the skeleton B and the position in the prospective direction are different between the portion where the horizontal frame is attached and the portion where the vertical frame is attached, the shapes of the respective frame outer constituent portions 12 can be matched. can be installed, which is advantageous in terms of versatility.

In addition, the position of the inner peripheral cover plate portion 12a4, which is the inner peripheral side of the frame outer forming portion 12, does not need to match the position of the projection surface 21m, which is the inner peripheral side of the face material support portion 21b. You may comprise so that it may become an inner peripheral side over the projection surface 21m used as the inner peripheral side of the face material support part 21b.

(Modification)
In order to more reliably prevent problems caused by direct irradiation of sunlight, it is possible to configure as in the modified examples shown in FIGS. That is, in the first modification shown in FIG. 8, the portion extending from the projection surface 21m that is the inner peripheral side of the face material support portion (outer base portion) 21b of the frame inner component portion 11 to the outside surface that is the outdoor side. A metal coating M is applied.

In the modification 2 shown in FIG. 9, as the supplemental frame-constituting portion 13, when the shoji 2 is closed, the prospective extension plate portion facing the prospective surface 21m that is the inner peripheral side of the face material support portion (outer base portion) 21b 13e is applied.

In Modification 3 shown in FIG. 10, as the face material supporting portion (outer base) 21b of the shoji 2, a face material sealing member 24 is attached to the part on the inside of the room. As the face material sealing member 24, a member having a cover portion 24a that covers the projection surface 21m on the inner peripheral side of the face material supporting portion 21b is applied. In modifications 1 to 3, the same reference numerals are assigned to the same configurations as in the first embodiment.

According to these modifications, in addition to the configuration of Embodiment 1, a member is provided to actively cover the projection surface 21m that is the inner peripheral side of the face material support portion 21b. It is possible to prevent direct irradiation of the face material supporting portion 21b even with sunlight irradiated from an oblique direction, and it is possible to more reliably solve the problems of surface deterioration and thermal deformation.

Further, in Modified Example 3, a metal reinforcement is provided to extend to the indoor side of the frame inner constituent portion 11 with respect to the outer peripheral cover plate portion (peripheral cover portion) 12a5' of the lower frame outer constituent portion 12B. A cover plate portion 12a9 is added. Therefore, in the fittings of Modification 3, it is possible to improve the rigidity of the lower horizontal frame. Moreover, the outer peripheral cover plate portion 12a5' and the reinforcing cover plate portion 12a9 are thermally insulated by the heat insulating material 12a10 interposed therebetween. That is, in the fittings of the modified example, the metal outer peripheral cover plate portion 12a5 continuous from the outdoor side extends further to the indoor side than the glass plate 3a1 arranged on the furthest outdoor side in the face material 3 of the shoji 2 in the projection direction. never exist. As a result, compared to the first embodiment, there is no possibility that the heat insulating property will be impaired.

(Embodiment 2)
In the first embodiment and modified examples 1 to 3 described above, the outer frame component 12 covers the face member support portion 21b, which is the outer base portion of the frame main body 21. However, the present invention does not necessarily Without being limited to this, for example, it is also possible to configure such that the outer base portion of the frame main body is covered by the supplemental frame-constituting portion, as in Embodiment 2 shown in FIGS. 11 and 12 .

Only the construction of the body 1 is different. Hereinafter, configurations different from those of the first embodiment will be described in detail, and configurations similar to those of the first embodiment will be assigned the same reference numerals, and detailed descriptions thereof will be omitted. Also, the vertical frame is basically the same as the frame building material 10 that serves as the lower horizontal frame, so illustration is omitted.

The frame building material 10 constituting the frame body 1 includes a frame inner component 11 made of resin, a frame outer component 12 made of metal such as aluminum alloy, and an auxiliary frame component 13 made of metal such as aluminum alloy.

The difference from the first embodiment is that it has two positioning ribs 12a7 and a hook piece 12k. The two positioning ribs 12a7 are provided at positions corresponding to the facing surface 11q, which is the exterior side of the frame contact portion 11b. The hook piece portion 12k extends toward the interior of the room from a portion of the cover plate portion 12a1 corresponding to the outer peripheral edge of the engaging plate portion 11p provided on the frame inner component portion 11, and then bends toward the inner peripheral side. It is what I did. The inner edge portion of the hook piece portion 12k is inclined toward the inner peripheral side so as to be gradually separated from the cover plate portion 12a1. The difference between the upper frame outer forming portion 12A and the lower frame outer forming portion 12B is the shape of the inner peripheral cover plate portion 12a4 and the dimension of the outer extension portion 12a3 along the outer direction.

As shown in FIG. 12(b), the inner peripheral cover plate portion 12a4 of the lower frame outer forming portion 12B extends only along the projected direction from the projected extension portion. The outer extension portion 12a3 of the lower frame outer component portion 12B becomes the inner peripheral side of the frame contact portion 11b when the engaging protrusion 11d of the frame inner component portion 11 is brought into contact with the outer peripheral cover plate portion 12a5. The dimensions are set so that a gap is secured between the projection surface and the inner peripheral cover plate portion 12a4 so that a holding piece portion of the complementary frame-constituting portion 13, which will be described later, can be held therebetween.

On the other hand, as shown in FIG. 12(c), the inner peripheral cover plate portion 12a4 of the upper frame outer component portion 12A is connected to the extension edge portion extending along the projection direction from the projection extension portion. It has a piece 12m. The auxiliary frame connecting piece portion 12m extends in the viewing direction from the inner peripheral cover plate portion 12a4 toward the outer peripheral side. The outer extending portion 12a3 of the upper frame outer forming portion 12A is configured to have a dimension larger than that of the lower frame outer forming portion 12B. The dimensions are set so that a gap can be secured between the projected surface, which is the inner peripheral side of the frame contact portion 11b, and the complementary frame connecting piece portion 12m when the frame contact portion 11b is brought into contact with the frame contact portion 11b.

The complementary frame-constituting portion 13 of the frame building material 10 has the same cross-sectional shape on all four circumferences, and has a complementary frame base portion 13a and a complementary frame surface material support portion (edge on the inner peripheral side) 13b. . The auxiliary frame base 13a has a rectangular hollow shape and has a support leg 13f on a portion on the outside of the room. The supporting leg portion 13f extends in the viewing direction toward the outer peripheral side, and has a clamping piece portion 13g on the extending edge portion. The holding piece portion 13g is bent substantially at a right angle from the support leg portion 13f toward the outdoor side. The extending dimension of the supporting leg portion 13f is set larger than the extending dimension of the reinforcing frame connecting piece portion 12m. The complementary frame surface material supporting portion 13b is the same as that provided in the first embodiment.

The above-described complementary frame-constituting portion 13 is formed in a rectangular shape by connecting the ends thereof. By press-fitting the periphery of the insect screen 4 together with the pressing rubber 4a into each of the supplementary frame member supporting portions 13b connected in the rectangular shape, the insect-proof auxiliary member 5 is constructed. will be The complementary frame-constituting portion 13 connected in a rectangular shape is connected to the inner peripheral cover plate when the end portions of the frame outer-constituting portion 12 are connected to the rectangular cylindrical portion formed by the respective holding pieces 13g. The dimensions are set so that the rectangular cylindrical portion formed by the portion 12a4 can be inserted. In other words, the insect-proof auxiliary surface member 5 is attached to the frame outer forming portion 12 in a state in which the auxiliary frame base portion 13a and the supporting leg portion 13f protrude inward from the inner peripheral cover plate portion 12a4.

In order to configure the frame body 1 with the frame inner component 11, the frame outer component 12, and the complementary frame component 13 configured as described above, both ends of the frame inner component 11 are formed as in the first embodiment. , and the ends of the frame inner component 11 are joined by welding through the inclined joint surfaces. From this state, after mounting the corresponding frame outer forming portions 12 to the respective frame inner forming portions 11, the ends of the frame outer forming portions 12 are connected to each other.

When the frame outer component 12 is attached to the frame inner component 11, the outer water stop material 17 is arranged in advance on the outer peripheral side of the hook piece 12k of the lower frame outer component 12B. , the inner water stop material 18 is disposed on the outer peripheral cover plate portion 12a5. When the hook piece portion 12k and the engaging plate portion 11p are engaged with each other from this state, the positioning rib 12a7 comes into contact with the outside surface of the frame contact portion 11b, which is the exterior side, and the engaging piece portion 12a8 is engaged. It is kept in contact with the end surface of the protrusion 11d facing the room. In this state, movement of the frame outer component 12 and the frame inner component 11 in directions away from each other is blocked, and the outer water stop material 17 is located between the cover plate portion 12a1 and the frame inner component. 11 is interposed in a state of being pressed between the facing surface 11m on the outdoor side of 11. Thereafter, by screwing the connection screw 19 into the fitting cover plate portion 12a1 from the indoor side through the frame abutting portion 11b, the state in which the frame inner forming portion 11 and the frame outer forming portion 12 are connected to each other is maintained. be.

With respect to the frame outer component 12 and the frame inner component 11 which are connected to each other on all four sides, the inner peripheral cover plate portion 12a4 is covered with the insect-proof auxiliary surface material 5, and the inner peripheral cover plate portion 12a4 is covered with the support leg portion 13f from the indoor side to the upper frame outer side. By screwing the screw 30 into the auxiliary frame connecting piece portion 12m of the structural portion 12A, the frame 1 in which the insect-proof auxiliary surface member 5 is supported by the frame outer structural portion 12 is constructed. In this frame 1, the opening is covered with the insect screen 4, preventing foreign matter from entering the room through the opening. In order to attach the frame 1 to the frame B, the frame support projection 12e and the auxiliary frame support projection 12f of the lower frame outer component 12B are brought into contact with the frame B, and the frame support 11c of the frame inner component 11 is attached. is brought into contact with the frame B, and from this state, the screws S are screwed into the frame B through the frame mounting plate portions 12a6 provided on the four peripheral frame outer component portions 12. As shown in FIG.

Here, the dimension along the length of the frame inner forming portion 11 constituting the frame 1 and the dimension along the length of the frame body 21 constituting the shoji 2 are the same as the frame building material 10 and the frame building material 20 around the four circumferences. In between, the secondary seal member 23 of the frame body 21 abuts on the interior facing surface 11k of the frame inner component 11, and the primary seal member 14 contacts the interior exterior surface 21k of the frame body 21. is set to abut on the Therefore, if the shoji 2 is supported by the frame 1 so as to be openable and closable while maintaining this state, when the shoji 2 is closed with respect to the frame 1, the primary sealing member 14 and the secondary sealing member are formed on the four circumferences. 23 are interposed between the frame 1 and the shoji 2 at the same time, so that desired airtightness and water stoppage can be ensured.

In addition, with respect to the frame building material 20 that constitutes the shoji 2, both the frame body 21 and the rim 22 are molded from resin, and with respect to the frame building material 10 that constitutes the frame body 1, the inside of the frame is molded from resin. The constituent part 11 occupies a region beyond the shoji 2 to a part on the outdoor side. In addition, the outer peripheral cover plate portion 12a5 of the frame outer component portion 12 made of metal terminates on the outdoor side in the perspective direction from the glass plate 3a1, which is arranged on the furthest outdoor side of the panel 3 of the shoji 2. Therefore, according to this fitting, the range affected by the temperature on the outdoor side is limited to the portion arranged on the outdoor side of the shoji 2, which is advantageous in terms of heat insulation. As a result, for example, even when the outdoor temperature is low, dew condensation is less likely to occur on the portions of the frame 1 and the shoji 2 that are exposed to the indoor side.

Moreover, in this fitting, the position of the supplementary frame surface material support portion 13b of the supplementary frame structure portion 13, which is the innermost peripheral side of the frame outer structure portion 12, is located inside the surface material support portion (outer base portion) 21b on all four sides. It is set so as to be on the inner peripheral side of the position of the prospective surface (edge portion on the inner peripheral side) 21m on the peripheral side. For this reason, the face material supporting portion 21b positioned on the outdoor side of the frame body 21 of the shoji 2 relative to the face material 3 becomes difficult to be visually recognized from the outdoor side along the viewing direction. Therefore, according to this fitting, it is possible to prevent direct sunlight from irradiating the face material supporting portion 21b of the frame body 21, and problems such as surface deterioration and thermal deformation are less likely to occur, which is advantageous in terms of weather resistance. Become.

Furthermore, between the frame inner component 11 and the frame outer component 12, an outer water stop material 17, a frame seal member 15, and an inner water stop material 18 are arranged from the outdoor side. Therefore, there is no possibility that outdoor water will enter the room through the joint between the frame inner component 11 and the frame outer component 12 .

In addition, in the first embodiment, the modified example, and the second embodiment described above, the inward-opening window is exemplified, but the present invention is not limited to this. As long as the shoji 2 does not protrude toward the outdoor side, it can also be applied to other fittings. Also, although the frame inner component 11 and the frame main body 21 are formed of resin, they can also be made of wood. Furthermore, as the frame inner constituent portion 11, the end portions are connected (welded) as an example, but if the frame outer constituent portion 12 is connected, the end portions of the frame inner constituent portion 11 can be connected (welded). are not necessarily connected.

Further, in Embodiment 1, Modified Example and Embodiment 2 described above, the connection screw 19 connecting between the frame inner component 11 and the frame outer component 12 is screwed only from the inside of the room. In addition, the frame inner component 11 can be removed from the indoor side without removing the frame outer component 12, making it possible to easily perform work such as fitting replacement or repair. However, the invention is not necessarily limited to this. Further, although the auxiliary frame-constituting part 13 is illustrated as holding the insect screen 4, it is not necessarily limited to this, and for example, other auxiliary surface materials such as a lattice and a screen may be held. .

According to this invention, since the frame main body made of resin has the outer base portion located on the outdoor side of the face material, it is possible to prevent the outdoor temperature from being conducted to the vicinity of the indoor space. It is advantageous in terms of heat insulation. In addition, since the outer base is covered with the frame outer component formed of metal, it is difficult to visually recognize the outer base from the outdoor side along the projection direction, so that the sunlight is not directly irradiated. It is also advantageous in terms of weather resistance.

Further, according to the present invention, in the fittings described above, the ends of the frame outer component are connected by flat joints, and the frame building material is provided with an attachment portion for attachment to the frame at the frame outer component. It is characterized by having
According to the present invention, it is not necessary for the cross-sectional shapes of adjacent ones to be the same as the frame-outer forming part whose ends are connected to each other by flat splicing.
