That is, the sash frame 3 of the present embodiment is a composite sash frame made of a combination of resin and metal.

  In the case of a composite sash frame containing resin, the resin portion (the heat insulating portions 11b and 12b in the present embodiment) is arranged on the indoor side of the composite sash frame. That is, in the case of a composite sash frame, the frame 91 is in the vicinity of the resin portion of the sash frame. When the frame 91 is fixed to the sash frame, the fixing strength may be insufficient in the resin portion of the sash frame. In addition, a thermal bridge is likely to be formed in the metal portion of the sash frame (main body portions 11a and 12a in this embodiment). Therefore, as in this embodiment, by fixing the frame 91 to the frame structure 100 via the support member 50, the formation of the thermal bridge is suppressed, and the heat insulating performance of the sash frame including resin at least partially is achieved. The frame 91 can be firmly fixed to the frame structure 100 via the support member 50 while maintaining.

  More specifically, the main body portions 11a and 12a of the sash frame 3 of the present embodiment are formed of aluminum, and the heat insulating portions 11b and 12b of the sash frame 3 of the present embodiment are formed of vinyl chloride. The frame structure 100 is made of steel. That is, the frame structure 100 as the interposition member X of the present embodiment has a lower thermal conductivity than the main body portions 11a and 12a of the sash frame 3, and a higher thermal conductivity than the heat insulating portions 11b and 12b of the sash frame 3. . As shown in FIG. 4, the support member 50 according to the present embodiment is partially separated from the sash frame 3 to the indoor side through the interposition member X having a lower thermal conductivity than the body portion 12 a of the sash frame 3. It is said. In the present embodiment, the plate-like projecting portion 52 of the support member 50 is separated from the main body portion 12a of the sash frame 3 to the indoor side by the frame structure 100 as the interposed member X. In this state, the support member 50 of the present embodiment is fixed to the frame structure 100 as the interposition member X by fastening members 8e such as screws and screws.

  More specifically, the frame structure 100 of the present embodiment includes a frame inner surface 101 positioned on the indoor side of the sash frame inner surface 12a1 on the indoor side of the sash frame 3 below the frame 91 in the vertical direction. The support member 50 is fixed to the frame inner surface 101. The sash frame inner surface 12a1 of the present embodiment is a surface on the indoor side of the main body 12a of the sash frame 3. Further, the frame inner surface 101 of the present embodiment is a surface on the indoor side of the first vertical plate portion 31 of the horizontal frame portion 5.

  That is, the support member 50 of the present embodiment is configured such that the plate-like projecting portion 52 of the support member 50 and the first vertical plate portion 31 of the horizontal frame portion 5 of the frame structure 100 are fastened by the fastening member 8e. It is fixed to the structure 100.

  As described above, the support member 50 is fixed to the frame inner surface 101 located on the indoor side further than the sash frame inner surface 12 a 1, so that the support member 50 is brought closer to the position directly below the frame 91. Since it can fix, the bending moment loaded with respect to the plate-shaped support part 51 of the supporting member 50 can be made small. Therefore, the member cross section of the support member 50 can be reduced. Thereby, the heat transfer through the support member 50 can be further suppressed.

  Furthermore, the support member 50 of the present embodiment includes a fixing portion 52a that is fixed to the frame structure 100 as the interposition member X. More specifically, the fixing portion 52a of the present embodiment is a portion in the vicinity of the insertion hole of the fastening member 8e provided in the plate-like protruding portion 52 of the support member 50. A plurality of the fixing portions 52a of the present embodiment are arranged apart from each other. The support member 50 is fixed to either the sash frame 3 or the interposition member X (in this embodiment, the frame structure 100 as the interposition member X) by the plurality of fixing portions 52a that are spaced apart in this way. For example, heat transfer between the sash frame 3 and the support member 50 can be further suppressed as compared with a configuration in which the entire region is fixed by welding or the like.

  In particular, it is preferable that the support member 50 be in contact with the sash frame 3 or the interposition member X only at the plurality of fixing portions 52a. If it does in this way, the contact area of the supporting member 50, the sash frame 3, and the interposition member X can be made smaller. As a result, heat transfer between the sash frame 3 and the support member 50 can be further suppressed.

  The sash frame 3 of this embodiment is a composite sash frame made of a combination of a resin and a metal, but is not limited to this configuration, and may be a resin sash frame having no metal portion.

  Further, as described above, in the horizontal sash frame portion 12 of the sash frame 3 of the present embodiment, the protruding plate portion 12c and the second vertical plate portion 33 of the horizontal frame portion 5 of the frame structure 100 are fastened by the fastening member 8d. As a result, the frame structure 100 is fixed. That is, the support member 50 and the sash frame 3 of the present embodiment are fixed at different positions on the horizontal frame portion 5 of the frame structure 100, and the metal main body portion 12 a of the sash frame 3 and the plate of the support member 50. The protrusions 52 are separated from each other in the indoor and outdoor directions. In other words, a gap is formed between the two. In this embodiment, the heat insulating material 9 is arrange | positioned in this space | gap.

  Further, the frame 91 of the present embodiment is supported from below by the interior material 1c and the base material 61 that fixes the interior material 1c, in addition to the support member 50, but is not limited to this configuration.

  FIG. 5 is a view of the support member 50, the horizontal frame portion 5, and the lower side portion 91 a of the frame 91 as viewed from the indoor side. As shown in FIG. 5, it is preferable that a plurality of support members 50 are arranged apart from each other along the length direction of the frame 91. In FIG. 5, the length direction of the frame 91 is the extending direction of the horizontal frame portion 5 (the direction C perpendicular to the thickness direction A in the horizontal direction). In this way, by arranging a plurality of support members 50 spaced apart along the length direction of the frame 91, compared to a case where only one support member extending along the length direction of the frame 91 is used. Thus, the contact area with the horizontal frame portion 5 can be reduced. That is, heat transfer between the frame structure 100 as the interposition member X and the support member 50 can be further suppressed.
