In addition, the thickness dimension of each groove part of the runners 43-46 is made the same. That is, the thickness dimension of each groove part of the intermediate runners 45 and 46 is also larger than the thickness dimension D1 of the gap stud 47B. Moreover, the runners 43 to 46 have a web and a pair of flanges arranged so as to sandwich the web, and a separation distance (thickness dimension of the groove part) between the flanges becomes a thickness dimension of the groove part. Yes.

  The thickness dimension of the short stud 47A is substantially the same as the thickness dimension D2 of each groove portion of the runners 43 to 46. In the short stud 47A, both the outdoor side surface and the indoor side surface are overlapped with the inner side surface of each flange of the runners 43 to 46, and the short stud 47A is fixed to the runners 43 to 46 by welding or the like. Has been. The short stud 47A corresponds to a thickness stud.

  On the other hand, the gap stud 47B is disposed at a position where the indoor side surface thereof overlaps the inner side surface of the indoor side flange in the runners 43 and 44. 44 is fixed by welding or the like. In this case, the outdoor side surface of the gap stud 47B is separated from the outdoor side flange in the runners 43 and 44 toward the indoor side, and is not fixed to the outdoor side flange. Therefore, it is considered that the fixing strength of the gap stud 47B with respect to the runners 43 and 44 is lower than the configuration in which both the indoor side face and the outdoor side face of the gap stud 47B are fixed to the flanges of the runners 43 and 44. . As a result, there is a concern that the support strength of the window frame 52 by the gap stud 47B is lowered.

  Therefore, in the present embodiment, the gap stud 47 </ b> B is connected to the column 13 via the connecting member 61. Thereby, it is suppressed that the support strength of the window frame 52 by the gap | interval stud 47B falls. The connecting member 61 includes a stud side fixing portion 62 fixed to the gap stud 47 </ b> B and a column side fixing portion 63 fixed to the column 13. The stud side fixing portion 62 extends from the column side fixing portion 63 along the wall thickness direction, and is fixed to the gap stud 47B by the first screw 65 in a state where the stud side fixing portion 62 is overlapped on the side surface of the gap stud 47B on the column 13 side. ing. The column-side fixing portion 63 extends from the stud-side fixing portion 62 along the wall width direction, and is fixed to the column 13 with a second screw 66 in a state of being superimposed on the indoor side surface of the column 13. The gap stud 47B corresponds to the gap member.

  Here, a connection structure between the gap stud 47 </ b> B and the column 13 connected by the connection member 61 will be described with reference to FIGS. 2 and 4. 4A and 4B are diagrams showing the configuration of the connecting member 61. FIG. 4A is a perspective view of the connecting member 61, and FIG. 4B is an exploded perspective view of the connecting structure of the column 13 and the gap stud 47B.

  As shown in FIG. 4A, the connecting member 61 has a pair of plate portions orthogonal to each other, one of the plate portions being a stud side fixing portion 62 and the other being a column side fixing portion 63. It is said that. The connecting member 61 is formed of a steel material such as a short angle material. The column-side fixing portion 63 is provided with a screw hole 63a for the second screw 66. The screw hole 63 a is a long hole extending along the extending direction of the column side fixing portion 63 from the stud side fixing portion 62, and extends along the boundary portion between the column side fixing portion 63 and the stud side fixing portion 62. Are lined up. In this case, the screw hole 63a extends in the horizontal direction along the wall width direction.

  The stud side fixing portion 62 is provided with a screw hole 62a for the first screw 65. The screw holes 62 a are round holes, and a plurality of screw holes 62 a are arranged along the boundary portion between the column side fixing portion 63 and the stud side fixing portion 62.

  As shown in FIG. 4B, a plurality of connecting members 61 are arranged side by side at a predetermined interval in the vertical direction. In the connecting member 61, the second screw 66 is attached to the column 13 through the screw hole 63 a of the column side fixing portion 63, whereby the connecting member 61 is fixed to the column 13. The first screw 65 penetrates the gap stud 47B and is attached to the screw hole 62a of the stud side fixing portion 62, whereby the connecting member 61 is fixed to the gap stud 47B.

  The outer peripheral portion of the gap stud 47B includes a pair of side portions facing each other, and the first screw 65 passes through one of these side portions. On the other hand, a working opening 67 is provided at a position facing the penetrating portion of the first screw 65, and the first screw 65 is inserted into the hollow portion of the gap stud 47 </ b> B through the working opening 67, and the first A tool such as a driver for performing the screwing operation of the screw 65 is inserted into the hollow portion of the gap stud 47 </ b> B through the work opening 67.

  As shown in FIG. 2, the stud-side fixing portion 62 of the connecting member 61 enters between the column 13 and the gap stud 47B from the indoor side, and overlaps the side surface of the gap stud 47B. Here, in the wall width direction, the width dimension W1 (for example, 25 mm) of the gap stud 47B is set to be smaller than the separation distance W2 between the vertical frame portion 52a of the window frame 52 and the column 13. Thus, even if the width dimension of the gap stud 47B is not sized to match the distance between the vertical frame portion 52a and the column 13, the connection member 61 and the gap stud 47B are used by using the connection member 61. Thus, the vertical frame portion 52a is fixed to the column 13.

  The clearance distance between the gap stud 47B and the column 13 is larger than the thickness dimension of the stud side fixing portion 62, and the stud side fixing portion 62 is in a state of being overlapped with the side surface of the gap stud 47B. It is separated from the column 13 toward the gap stud 47B. The first screw 65 penetrates the screw hole 62a of the stud side fixing portion 62 and protrudes to the column 13 side. However, the protruding dimension is smaller than the separation distance between the stud side fixing portion 62 and the column 13. It is not attached to the pillar 13.

  The inner wall surface material 41 is separated from the pillar 13 in the wall thickness direction toward the indoor side, and the pillar side fixing portion 63 of the connecting member 61 is in the separated portion. In this case, the separation distance between the inner wall surface material 41 and the column 13 is smaller than the thickness dimension of the column side fixing portion 63, and the column side fixing portion 63 is separated from the inner wall surface material 41 to the outdoor side.

  The stud side fixing portion 62 of the connecting member 61 does not protrude to the outdoor side from the upper runner 43 and the lower runner 44 in the wall thickness direction. In the connecting member 61, the extension dimension of the stud side fixing part 62 from the column side fixing part 63 is made smaller than the thickness dimension of the gap stud 47B in the wall thickness direction. In this case, the connecting member 61 is disposed on the indoor side with respect to the wall heat insulating portion 48.

  The wall heat insulating part 48 includes a gap heat insulating part 48a that enters from the outdoor side between the column 13 and the vertical frame part 52a of the window frame 52, a column side heat insulating part 48b provided on the outdoor side of the column 13, and a column. It has a main heat insulating part 48c arranged on the opposite side to the gap heat insulating part 48a across the side heat insulating part 48b. These heat insulating portions 48a to 48c are all formed in a plate shape by a foam heat insulating material, and are arranged side by side along the wall width direction in a state where the side surfaces thereof are overlapped with each other. That is, the heat insulating portions 48a to 48c are in a continuous state. Further, in this case, the side surface of the gap heat insulating portion 48 a on the window portion 12 side overlaps the side surface of the column side protrusion 53 b (the mounting member 58) of the sash frame 51.

  The gap heat insulating portion 48a does not protrude indoors from the upper runner 43 and the lower runner 44, and is separated from the gap stud 47B to the outdoor side. In the gap heat insulating portion 48a, the side surface on the column side heat insulating portion 48b side is overlapped with the side surface of the column 13, and is also overlapped on the side surface of the vertical frame portion 52a, and between the column 13 and the vertical frame portion 52a. Insulates heat. Here, the stud-side fixing part 62 of the connecting member 61 is separated from the gap heat insulating part 48a to the indoor side. In this case, for example, unlike the configuration in which the stud-side fixing portion 62 enters between the column 13 and the gap heat insulating portion 48a, the heat insulating performance by the gap heat insulating portion 48a is not reduced by the stud side fixing portion 62.

  An operation procedure for fixing the gap stud 47B to the column 13 will be briefly described.

  First, the column side fixing portion 63 of the connecting member 61 is overlapped on the outdoor side surface of the column 13, and in this state, the second screw 66 is driven into the column 13 from the screw hole 63 a to fix the connecting member 61 to the column 13. Here, in the wall width direction, the installation positions of the window frame 52 and the gap stud 47B are determined in advance, and the fixing position of the connecting member 61 with respect to the column 13 is set so that the stud side fixing portion 62 contacts the side surface of the gap stud 47B. To decide.

  Then, the gap stud 47B is disposed at a position where it abuts against the side surface of the stud-side fixing portion 62, and the first screw 65 is driven toward the stud-side fixing portion 62 from the gap stud 47B side. Here, in the wall thickness direction, the installation position of the inner wall surface material 41 is determined in advance, and the gap stud 47B with respect to the connecting member 61 is placed so that the indoor side surface of the gap stud 47B abuts the outdoor side surface of the inner wall surface material 41. Determine the fixed position. In this case, since the screw hole 62a of the stud side fixing portion 62 extends along the wall thickness direction, the position adjustment of the gap stud 47B with respect to the stud side fixing portion 62 can be easily performed when the first screw 65 is driven. Can do.

  After fixing the gap stud 47B to the column 13 using the connecting member 61, the inner wall surface material 41 and the vertical frame portion 52a are fixed to the gap stud 47B with screws or the like.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the vertical frame portion 52a of the window frame 52 is fitted between the pair of protrusions 53a, 53b of the sash frame 51, the vertical frame portion 52a can be suitably held by the sash frame 51. Moreover, since the distance between the pair of projections 53a and 53b is adjusted by the mounting member 58 so that the vertical frame 52a fits between the pair of projections 53a and 53b, for example, the sash frame 51 and Even when the vertical frame portion 52a and the pair of protrusions 53a and 53b are not compatible with each other, such as when the window frame 52 is a general-purpose product or manufactured by different manufacturers, the vertical frame portion 52a The projections 53a and 53b can be fitted. Therefore, the vertical frame portion 52 a of the window frame 52 can be suitably held by the vertical frame portion 51 a of the sash frame 51.

  Since the gap heat insulating portion 48a is pushed between the mounting member 58 of the column side protruding portion 53b and the column 13, the gap heat insulating portion 48a is connected to the mounting member 58 and the column 13 of the column side protruding portion 53b. Since both are in contact with each other, even if a gap is secured between the window frame 52 and the pillar 13, the gap does not become a non-insulating region. Therefore, in the configuration in which the vertical frame portion 52a of the window frame 52 is held by the sash frame 51, it is possible to suppress the heat insulation performance of the outer wall portion 11 from being deteriorated.

  In the wall heat insulating part 48, since two heat insulating members such as the gap heat insulating part 48a and the column side heat insulating part 48b are arranged side by side in the wall width direction, one heat insulating member arranged on the outdoor side of the column 13 is the column side. Compared to the configuration entering between the protruding portion 53 b and the column 13, the gap heat insulating portion 48 a and the column side heat insulating portion 48 b are easily in close contact with the side surfaces of the column side protruding portion 53 b and the column 13. Therefore, the heat insulation performance of the outer wall part 11 by the wall heat insulation part 48 can be improved.

  There is a concern that the stability of the installation state of the window frame 52 will be insufficient if the window frame 52 is merely held by the pair of protrusions 53a and 53b of the sash frame 51. Since it is being fixed with respect to it, stability of the installation state of the window frame 52 can be improved. In addition, in the configuration in which the wall heat insulating portion 48 enters between the window frame 52 and the column 13, there is a concern that the window frame 52 cannot be fixed to the column 13. Since the gap stud 47B is provided between the column 13 and the column 13, the window frame 52 can be fixed to the column 13 in an appropriate state via the gap stud 47B.

  Since the gap stud 47B is disposed at the indoor position in the wall thickness direction due to the inner wall surface material 41 being attached, the gap stud 47B supports the indoor portion of the vertical frame portion 52a of the window frame 52. However, even in this case, the position of the outdoor frame side end of the vertical frame portion 52a is held by the pair of protrusions 53a and 53b of the sash frame 51, so that the installation state of the window frame 52 is stable. Can increase the sex.

  In the column-side projection 53b, the mounting member 58 is mounted on the projection 57, so that the separation distance between the window-side projection 53a and the mounting member 58 is the separation distance L2 between the window-side projection 53a and the projection 57. Since it is the same as the width dimension L1 of the vertical frame part 52a of the smaller window frame 52, the structure which the vertical frame part 52a fits between a pair of projection part 53a, 53b is realizable. That is, even when the separation distance L2 between the window-side protruding portion 53a and the convex portion 57 is larger than the width dimension L1 of the vertical frame portion 52a, the vertical frame portion 52a of the window frame 52 can be held by the sash frame 51.

  While the column-side protrusion 53b has the mounting member 58, the window-side protrusion 53a does not have the mounting member 58. Therefore, the mounting member 58 is moved from the window 12 side by the vertical frame portion 52a of the window frame 52. Can be obscured. Therefore, it can suppress that the design property of the window part 12 falls by the mounting member 58. FIG.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) A partition wall may be connected to the outer wall portion 11. For example, as shown in FIGS. 5 and 6, a partition wall 71 orthogonal to the outer wall portion 11 is connected to the outer wall portion 11. FIG. 5 is a cross-sectional view of a connecting portion between the outer wall portion 11 and the partition wall 71, and FIG. 6 is a perspective view of the outer wall portion 11 and the partition wall 71. In FIG. 6, the outer wall frame 35, the inner wall surface material 41, the window frame 52, the sash frame 51, and the partition wall surface material 72 are not shown. 5 is a cross-sectional view taken along the line BB in FIG.

  In this configuration, the partition wall 71 has a pair of partition wall materials 72 facing each other and a partition wall base 73 provided between the partition wall materials 72, and the outdoor side end surface is the outer wall portion 11. Connected to the indoor surface. In the connection portion between the partition wall 71 and the outer wall portion 11, a connection opening 75 is provided in the inner wall surface material 41 of the outer wall portion 11, and the inner wall base 42 of the outer wall portion 11 is connected via the connection opening 75. The partition wall base 73 is connected to the partition wall 71. Further, the outdoor side end surface of the partition wall surface material 72 of the partition wall 71 is overlapped with the indoor surface of the inner wall surface material 41 of the outer wall portion 11.

  The pillar 13 is included in the lattice pillar. The lattice pillar has a pair of pillars 13 arranged at a predetermined interval in the wall width direction, and a lattice 77 connecting the pillars 13. In the configuration in which the lattice 77 is provided inside the outer wall portion 11, the column-side heat insulating portion 48 b is provided not only on the outdoor side of the column 13 but also on the outdoor side of the lattice 77. Further, the inner wall base 42 is provided on the indoor side of the lattice 77, and the thickness dimension of the inner wall base 42 is smaller than the thickness dimension of the inner wall base 42 of the above-described embodiment. For example, the thickness dimension of the stud 47 provided on the indoor side of the lattice 77 is smaller than the thickness dimension of the gap stud 47B (for example, 25 mm).

  (2) In the above embodiment, in the column side protrusion 53b, the projection 57 is inserted into the recess 58a of the mounting member 58, so that the mounting member 58 covers the projection 57 from the indoor side. However, the mounting member 58 only needs to be mounted on the convex portion 57 in a state where at least a part of the mounting member 58 is disposed between the convex portion 57 of the window side protruding portion 53a and the column side protruding portion 53b. For example, the mounting member 58 is arranged side by side on the convex portion 57 in the wall width direction and fixed to the convex portion 57 in that state.

  (3) In the above-described embodiment, the window-side protrusion 53a does not have the mounting member 58, but the window-side protrusion 53a includes a protrusion extending from the vertical frame 51a of the sash frame 51 toward the indoor side, You may comprise including the attachment member with which the convex part was mounted | worn. In this case, the mounting member included in the window side protrusion 53a has a smaller distance between the window side protrusion 53a and the column side protrusion 53b than the distance between the protrusion of the window side protrusion 53a and the column side protrusion 53b. This corresponds to the adjusting unit. Therefore, at least one of the pair of protrusions 53a and 53b only needs to have a mounting member as an adjustment portion.

  (4) In the column-side protrusion 53b, the mounting member 58 extends in the vertical direction along the convex portion 57. However, a plurality of mounting members 58 may be provided side by side at predetermined intervals along the vertical direction. . In this case, in the vertical direction, the distance between the pair of protrusions 53a and 53b differs between the portion where the mounting member 58 is provided and the portion where the mounting member 58 is not provided, but the mounting member 58 is provided. In the portion, the position of the vertical frame portion 52a of the window frame 52 can be held by the pair of projecting portions 53a and 53b.

  (5) In the above embodiment, the width dimension L1 of the vertical frame portion 52a of the window frame 52 is smaller than the separation distance L2 between the convex portion 57 of the column side protrusion 53b and the window side protrusion 53a. The width dimension L1 of the frame part 52a may be made larger than the separation distance L2 between the convex part 57 and the window side projection part 53a. That is, L1> L2 may be used instead of L1 <L2. For example, as shown in FIG. 7, the mounting member 58 is not mounted on the convex portion 57 of the vertical frame main body 55a, the convex portion 57 is a column-side protruding portion 53b, and the width dimension L1 of the vertical frame portion 52a. Is larger than the separation distance L2 between the pair of protrusions 53a and 53b.

  The vertical frame portion 52a of the window frame 52 is formed with a concave portion 78 that is recessed toward the indoor side. In the vertical frame portion 52a, the concave portion 78 is arranged side by side along the wall width direction. The portion is a side-by-side portion 79. In addition to the outdoor side, the recessed part 78 is a notch part opened toward the opposite side (column 13 side) from the window part 12, and extends along the wall height direction. Between the pair of protrusions 53a and 53b of the sash frame 51, the side-by-side portion 79 of the window frame 52 enters from the indoor side, and the side-by-side portion 79 corresponds to the entering portion. The width dimension of the side-by-side portion 79 is the same as or slightly larger than the distance L2 between the pair of projecting portions 53a and 53b, and the side-by-side portion 79 is fitted between the pair of projecting portions 53a and 53b. It has become. In this case, the columnar protrusion 53 b is inserted into the recess 78 of the window frame 52.

  By forming the recessed portion 78 in the vertical frame portion 52a, even when the width dimension L1 of the vertical frame portion 52a is larger than the separation distance L2 between the pair of protrusions 53a and 53b, the vertical frame portion 52a of the window frame 52 The side-by-side portions 79 (outdoor end portions) can be fitted between the pair of protrusions 53a and 53b of the sash frame 51. That is, the configuration in which the vertical frame portion 52 a is held by the sash frame 51 can be realized by the recessed portion 78. Moreover, since the recessed portions 78 are disposed on the opposite side of the window portion 12 with the side-by-side portions 79 interposed therebetween, the recessed portions 78 are not exposed to the window portion 12 side. Thereby, it can suppress that the designability of the window part 12 falls by the dent part 78 of the window frame 52. FIG.

  Unlike the above-described embodiment, the side surface of the gap heat insulating portion 48a is overlapped with the side surface of the vertical frame portion 52a of the window frame 52. That is, the vertical frame portion 52a and the gap heat insulating portion 48a are in contact with each other. For this reason, even if the mounting member 58 does not enter between the vertical frame portion 52a and the gap heat insulating portion 48a, the heat insulating performance of the outer wall portion 11 is reduced at the boundary between the vertical frame portion 52a and the gap heat insulating portion 48a. That is suppressed. The recessed portion 78 is arranged on the outdoor side in the wall thickness direction from the indoor side end portion of the gap heat insulating portion 48 a, and the gap heat insulating portion 48 a does not enter the inside of the recessed portion 78.

  In addition, the clearance heat insulation part 48a may be provided in a state of entering the inside of the recess part 78. In particular, when the recessed portion 78 extends to the indoor side with respect to the gap heat insulating portion 48 a in the wall thickness direction, the gap heat insulating portion 48 a is preferably in contact with the inner peripheral surface of the recessed portion 78. Thereby, it can suppress that the heat insulation performance of the outer wall part 11 falls by the clearance gap between the side-by-side part 79 of the window frame 52, and the clearance heat insulation part 48a.

  Moreover, the dent part 78 does not need to be open | released toward the opposite side to the window part 12 in the wall width direction. For example, the side-by-side portions 79 may be arranged on both sides of the dent portion 78, and one of the side-by-side portions 79 may be an intrusion portion that enters between the pair of projecting portions 53a and 53b. By the way, it is preferable that the side-by-side portion 79 arranged on the window portion 12 side of the two side-by-side portions 79 enters between the pair of protrusions 53a and 53b. This is because the recessed part 78 is exposed to the window part 12 side rather than the covering member 55b (window side protrusion part 53a), and there is a concern that the design of the window part 12 may be deteriorated by the recessed part 78.

  The recess 78 may be a notch that is open toward the window 12 in the wall thickness direction. Even in this case, the side-by-side portion 79 of the window frame 52 can be fitted between the pair of protrusions 53a and 53b of the sash frame 51.

  Even when the concave portion 78 is formed in the vertical frame portion 52a of the window frame 52, the mounting member 58 may be mounted on the convex portion 57 of the column side protrusion 53b. That is, the mounting member 58 as an adjustment unit that reduces the separation distance L2 between the pair of protrusions 53a and 53b, and the adjustment unit that reduces the width dimension of the side-by-side portion 79 (entrance portion) of the window frame 52. Both the recess 78 may be provided.

  (6) In the above embodiment, the gap heat insulating portion 48a is separated from the vertical frame portion 52a of the window frame 52 in the wall width direction, but the vertical frame portion of the window frame 52 on the indoor side from the column side protrusion 53b. It may be in contact with 52a. In this case, it can suppress more reliably that the heat insulation performance of the outer wall part 11 falls between the clearance heat insulation part 48a and the vertical frame part 52a of the window frame 52. FIG.

  (7) In the above embodiment, the wall heat insulating portion 48 is formed by arranging the gap heat insulating portion 48a, the column side heat insulating portion 48b, and the main heat insulating portion 48c side by side. One heat insulating portion extending along the width direction may be installed in a state of being inserted between the column 13 and the window frame 52.

  (8) In the above embodiment, the gap stud 47B protrudes upward and downward from the window frame 52. However, the gap stud 47B does not protrude from the window frame 52 in at least one of the upper and lower sides. Good. For example, as shown in FIG. 8, the gap stud 47 </ b> B is configured not to protrude both above and below the window frame 52. In this configuration, the gap stud 47 </ b> B is provided between the upper intermediate runner 45 and the lower intermediate runner 46.

  Between the column 13 and the window frame 52, an upper connection runner 81 provided below the upper intermediate runner 45 and a lower connection runner 82 provided above the lower intermediate runner 46 are provided. Therefore, the gap stud 47B is in a state of being stretched over the connection runners 81 and 82. The upper connection runner 81 is fixed to the lower surface of the upper intermediate runner 45 with the groove facing downward, and the lower connection runner 82 is fixed to the upper surface of the lower intermediate runner 46 with the groove facing upward. Has been.

  The clearance stud 47B is fixed to the connection runners 81 and 82 by welding or the like in a state where the clearance stud 47B enters the groove portions of the connection runners 81 and 82, similarly to the configuration fixed to the upper runner 43 and the lower runner 44. Here, the connection runners 81 and 82 have a thickness dimension in the wall thickness direction smaller than the runners 43 to 46 in accordance with the thickness dimension of the gap stud 47B. In this case, in the connection runners 81 and 82, the side surface of the gap stud 47B is overlapped with both of the pair of flanges, and the overlapped portion is fixed by welding or the like. Thus, the gap stud 47B is firmly fixed to the intermediate runners 45 and 46 via the connection runners 81 and 82.

  Short studs 47A are installed above and below the gap studs 47B, and the short studs 47A and the gap studs 47B are arranged side by side.

  Further, the gap stud 47 </ b> B may protrude only upward or downward from the window frame 52. For example, when the gap stud 47 </ b> B protrudes above the window frame 52, the gap stud 47 </ b> B is preferably spanned between the upper runner 43 and the lower connection runner 82. In addition, when the gap stud 47 </ b> B protrudes below the window frame 52, the gap stud 47 </ b> B is preferably spanned between the lower runner 44 and the upper connection runner 81.

  (9) In the above embodiment, the gap stud 47 </ b> B, which is the object to be fixed to the inner wall surface material 41, is provided in the gap between the pillar 13 and the window frame 52. May be provided with a gap member that is not a target for fixing the inner wall surface material 41. That is, a gap member that does not constitute the inner wall base 42 may be provided. For example, a support bracket that is attached to the pillar 13 and supports the window frame 52 is provided in a gap between the pillar 13 and the window frame 52.
