  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  The outer wall structure of a building of the first invention is an outer wall structure of a building in which a wall opening is provided in an outer wall portion including an outer wall panel, and the outer wall panel includes an outer wall surface material and the outer wall structure. An outer wall base attached to an indoor side surface of the wall material, and the wall opening is provided with an opening frame extending along the wall opening. The frame material along the opening extends along the outer peripheral surface of the opening frame, and the frame material along the opening is fixed to the opening frame in a state of extending along the longitudinal direction of the frame material along the opening. A frame main body, and a deflection restricting portion protruding from the frame main body toward the opening frame and extending along a longitudinal direction of the frame main body.

  According to the first invention, in the frame material along the opening, even if a load from the opening frame is applied, the bending restriction portion prevents the frame body from bending in the direction in which the opening frame and the frame material along the opening are aligned. Can be suppressed. For example, in the case where the frame material along the opening is a stud extending in the vertical direction, the deflection regulating portion can suppress the stud from being bent in the wall width direction. Moreover, when the frame material along the opening is a runner extending in the left-right direction, it is possible to suppress the runner from being bent in the wall height direction by the bending restricting portion. Moreover, since the deflection restricting portion protrudes toward the opening frame, it is possible to fix the opening frame to both the frame body and the deflection restricting portion. As a result, the fixing strength of the opening frame to the frame material along the opening is increased. Can be increased. Therefore, in the outer wall portion having the wall opening, the opening frame provided in the wall opening can be favorably supported by the outer wall base.

In the runner protruding portion 71, each of the protruding plate portion 71 a and the connecting plate portion 71 b has the same length dimension as the runner protruding portion 71. In the runner protrusion 71, the connecting plate 71b corresponds to an orthogonal plate that is orthogonal to the protrusion 71a.

  In the intermediate runners 21 </ b> C and 21 </ b> D, the height dimension of the runner protrusion 71 is smaller than the height dimension of the runner body 73 in the wall height direction. Further, when the upper intermediate runner 21C and the lower intermediate runner 21D are compared, the height dimension (for example, 32.5 mm) of the runner protrusion 71 of the lower intermediate runner 21D is higher than the height of the runner protrusion 71 of the upper intermediate runner 21C. It is larger than the size (for example, 22 mm).

  In the intermediate runners 21 </ b> C and 21 </ b> D, the thickness dimension (for example, 37.5 mm) of the runner protrusion 71 is larger than ½ of the thickness dimension (73 mm) of the runner body 73 in the wall thickness direction.

  In the wall thickness direction, the thickness dimension of the runner protrusion 71 is made smaller than the thickness dimension of the runner body 73, and thereby, between the runner body 73 and the upper frame portion 41 b or the lower frame portion 41 c in the wall thickness direction. In this case, there are an installation area where the runner projection 71 is installed and a non-installation area where the runner projection 71 is not installed.

  The runner protrusion 71 is disposed at a position closer to the interior of the runner body 73 in the wall thickness direction. In this case, between the runner main body 73 and the sash frame 41, the installation area in which the runner protrusion 71 is installed is arranged indoors more than the non-installation area in which the runner protrusion 71 is not installed. The installation area and the non-installation area are aligned in the wall thickness direction. Here, the runner body 73 and the runner protrusion 71 have the same indoor side surface.

  In the intermediate runners 21C and 21D, the runner main body 73 corresponds to a frame main body, and the pair of flanges 73b of the runner main body 73 corresponds to a pair of opposed plate portions. Further, the configuration in which the indoor projecting plate portion 71a of the runner projecting portion 71 projects from the indoor flange 73b of the runner main body 73 toward the sash frame 41 is such that the runner projecting portion 71 is a pair of opposing frames. It protrudes from one opposing board part among board parts toward an opening frame.

  As shown in FIGS. 3, 4, and 7, the connecting frame body 53 of the sash frame 41 is fixed to the runner main bodies 73 of the intermediate runners 21 </ b> C and 21 </ b> D. The connecting frame 53 is fixed with screws 75 in a state where the indoor side surface of the connecting frame 53 is overlapped with the runner body 73 on the outdoor side surface. The screws 75 penetrate the connecting frame 53 from the outdoor side and are attached to the flange 73b on the outdoor side of the runner body 73. The position where the screw 75 is attached is a joint between the sash frame 41 and the outer wall surface material 17, and the screw 75 is covered from the outdoor side by a sealing material filled in the joint.

  The intermediate runners 21 </ b> C and 21 </ b> D support the main frame 51 of the sash frame 41. In the upper frame portion 41 b of the sash frame 41, the main frame body 51 is fixed to the upper intermediate runner 21 </ b> C with screws 76. In this case, the screw 76 penetrates the main frame 51 from below and is attached to the connecting plate portion 71b of the runner protrusion 71, whereby the upper intermediate runner 21C supports the main frame 51 from above. ing. Further, the screw 76 fixes the protruding member 56 to the main frame 51 in the upper frame portion 41b. In this case, the protruding member 56 is disposed on the opposite side of the runner protruding portion 71 across the main frame 51, and the screw 76 penetrates not only the main frame 51 but also the protruding member 56.

  In the lower frame portion 41c of the sash frame 41, the main frame body 51 is fixed in a state of being placed on the lower intermediate runner 21D, whereby the lower intermediate runner 21D moves the main frame body 51 from below. I support it. Further, in the lower frame portion 41 c, the protruding member 56 is attached in a state where it is engaged with the main frame body 51.

  For the intermediate runners 21C and 21D, the main frame fixing portion 51a of the main frame 51 is disposed on the outdoor side of the runner protruding portion 71, and the main frame fixing portion 51a and the runner protruding portion 71 are aligned in the wall thickness direction. It is out. In this case, the main frame fixing portion 51a and the connecting frame 53 enter the non-installation area where the runner protrusion 71 is not installed from the window 12 side in the area between the runner main body 73 and the main frame 51. It is in a state. In other words, the runner protrusion 71 enters the non-installation area where the connection frame 53 is not installed from the indoor side in the area opposite to the window 12 with the main frame 51 interposed therebetween. Yes. In this case, the outdoor side surface of the runner protrusion 71 and the indoor side surface of the main frame fixing portion 51a are overlapped.

  The intermediate runners 21 </ b> C and 21 </ b> D are stretched over a pair of side studs 22 </ b> B arranged with the window portion 12 interposed therebetween, and are supported by the side studs 22 </ b> B. As described above, the short stud 22A is fixed in a state where it enters the grooves of the intermediate runners 21C and 21D, but the side stud 22B extends upward and downward beyond the intermediate runners 21C and 21D. The intermediate runners 21C and 21D are fixed to the intermediate portion of the side stud 22B in the wall height direction.

  Here, a connection structure between the side stud 22B and the intermediate runners 21C and 21D will be described. Here, the connection structure of the upper intermediate runner 21C to the side stud 22B and the connection structure of the lower intermediate runner 21D are the same except that the upper and lower sides are reversed. The connection structure with the lower intermediate runner 21D will be described, and the description of the connection structure between the side stud 22B and the upper intermediate runner 21C will be omitted.

  As shown in FIGS. 5A and 5B, the lower intermediate runner 21 </ b> D is formed with a recessed portion 78 having a recessed end surface, and the side stud 22 </ b> B enters the recessed portion 78. In the runner main body 73, the web 73a is notched by the recess 78, while neither of the pair of flanges 73b is notched. In the wall thickness direction (the direction in which the pair of flanges 73b are arranged), the width dimension of the recess 78 is the same as the distance between the pair of flanges 73b, and in the portion of the runner body 73 where the recess 78 is provided, There is no web 73a between the flanges 73b. In this case, the portions of the pair of flanges 73b that protrude from the web 73a toward the side stud 22B are opposed to each other with the concave portion 78 (side stud 22B) interposed therebetween, and the side stud 22B is a pair of flanges 73b. It is in the state where it was pinched from the indoor outside.

  In the wall thickness direction, the thickness dimension of the side stud 22 </ b> B is the same as the distance between the pair of flanges 73 b of the runner body 73. In this case, the outdoor surface and the indoor surface of the side stud 22B overlap with the inner surface of each flange 73b, and the flange 73b is fixed to the side stud 22B by welding or the like in the overlapping portion.

  In the wall width direction (longitudinal direction of the lower intermediate runner 21D), the recess dimension of the recess 78 is smaller than the width dimension of the side stud 22B (the sum of the width dimension of the stud main body 63 and the width dimension of the protruding member 64). Thus, it is larger than the width dimension of the protruding member 64. In this case, the pair of flanges 73b of the lower intermediate runner 21D does not protrude to the opposite side of the side stud 22B, while the boundary between the stud body 63 and the protruding member 64 in the side stud 22B extends in the wall width direction. Straddling. In this case, the flange 73b overlaps both the stud body 63 and the protruding member 64, and is fixed to both the stud body 63 and the protruding member 64 by welding or the like.

  In the runner protruding portion 71, a portion that overlaps with the web 73a of the runner main body 73 (outside protruding plate portion 71a and connecting plate portion 71b), and a portion that is aligned in the wall width direction (indoor side) The protruding plate portion 71a) is cut away by the recess 78. That is, the entire front end side is cut away from the portion overlapping the recess 78 in the vertical direction.

  In the plan view, the recess 78 has a rectangular shape. In the wall thickness direction, the thickness dimension of the protruding member 64 of the side stud 22B is smaller than the thickness dimension of the runner protruding portion 71 of the lower intermediate runner 21D. In this case, the end surface of the connecting plate portion 71b of the end surface of the runner protrusion 71 overlaps the outer surface of the flange 64b of the protrusion member 64, and the runner protrusion 71 is welded to the protrusion member 64 in the overlapping portion. It is fixed by etc.

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

  Since the side stud 22B is formed by two members, ie, the stud main body 63 and the protruding member 64, only the protruding member 64 can be replaced in accordance with the type and shape of the sash frame 41. For example, when the width dimension or height dimension of the sash frame 41 is changed due to a design change or the like, the separation distance between the sash frame 41 and the stud main body 63 increases or decreases. By using the projecting member 64, the sash frame 41 can be supported by the projecting member 64 without changing the entire side stud 22B to a dedicated product. Incidentally, the portion of the sash frame 41 arranged on the outdoor side of the stud main body 63 is the stud main body in the wall thickness direction even if the separation distance in the wall width direction between the outer peripheral surface of the sash frame 41 and the stud main body 63 is slightly changed. If there is a portion that overlaps 63, that portion can be fixed to the stud body 63.

  In addition, since the stud body 63 can support the load that the side stud 22B should bear on the outer wall base 18, it is necessary to greatly change the structure of the outer wall base 18 even if the protruding member 64 is changed. Absent.

  As described above, in the outer wall portion 11 having the window portion 12, the sash frame 41 provided on the window portion 12 can be suitably supported by the outer wall base 18.

  In the wall thickness direction, the thickness of the protruding member 64 is smaller than that of the stud body 63, so that the protruding member 64 can be installed in accordance with the recessed portion of the outer peripheral surface of the sash frame 41. In this case, the recessed portion can be effectively used as an installation space for the protruding member 64 without making it a dead space. In this case, the entire portion of the outer peripheral surface of the sash frame 41 facing the side stud 22B in the wall thickness direction can be supported by the stud body 63 and the protruding member 64. Thereby, the fixed intensity | strength of the sash frame 41 with respect to the side stud 22B can be raised.

  Since the protruding member 64 of the side stud 22B is disposed on the indoor side of the connecting frame 53 of the sash frame 41 in the wall thickness direction, the protruding member 64 can be covered from the outdoor side by the sash frame 41. Thereby, it can suppress that the external appearance of the outer wall part 11 from the outdoor side is impaired by the protrusion member 64. FIG.

  In the wall thickness direction, the projecting member 64 is arranged on the outer peripheral surface of the sash frame 41 in accordance with the irregularities of the outer peripheral surfaces of the main frame 51, the connecting frame 53, and the finishing frame 52. All of the main frame 51, the connecting frame 53, and the finishing frame 52 can be fixed to the member 64 and the stud main body 63. For this reason, it can suppress that the fixed intensity | strength of the sash frame 41 with respect to the side stud 22B falls by presence of the connection frame 53. FIG.

  Since the protruding member 64 extends in the vertical direction along the stud main body 63 in the side stud 22B, the stud main body 63 can be prevented from being bent in the wall thickness direction or the wall width direction. This increases the strength of the side stud 22B. In addition, since the protruding member 64 is fixed to each of the upper runner 21 </ b> A and the lower runner 21 </ b> B together with the stud main body 63, the synthesis of the side stud 22 </ b> B can be enhanced by the protruding member 64. For this reason, the load applied to the side stud 22 </ b> B from the sash frame 41 or the like can be suitably supported by both the stud main body 63 and the protruding member 64.

  In the configuration in which the intermediate runners 21C and 21D are fixed to the side studs 22B by welding in the outer wall base 18, the welding may cause warpage (deflection) of the side studs 22B. On the other hand, in the side stud 22 </ b> B, the protruding member 64 can suppress the deflection of the stud body 63. And since the protrusion member 64 is being fixed to both the upper runner 21A and the lower runner 21B, the bending suppression effect of the stud main body 63 by the protrusion member 64 is heightened.

  At the connecting portion between the side stud 22B and the intermediate runners 21C, 21D, the side stud 22B is in a state where it enters the recess 78 of the intermediate runners 21C, 21D, so a part of the intermediate runners 21C, 21D (runner body) The intermediate runners 21 </ b> C and 21 </ b> D can be fixed to the side studs 22 </ b> B with the flange 73 b) 73 superimposed on the side studs 22 </ b> B in the wall thickness direction. Thereby, the connection strength of the intermediate runners 21C and 21D and the side studs 22B can be increased. In addition, in this case, it is not necessary to use a dedicated fixing member that is attached so as to straddle the boundary between the intermediate runners 21C and 21D and the side stud 22B in the wall width direction, so that the cost burden can be reduced.

  In the protruding member 64 of the side stud 22B, one of the pair of flanges 64b is fixed to the stud main body 63 and the other is fixed to the sash frame 41. Therefore, the stud main body 63 holds the sash frame 41 in an appropriate state. Can be supported. Moreover, since the stud main body 63 and the protruding member 64 are each formed of a general-purpose member called a grooved steel, the cost burden can be reduced. In addition, since the projecting member 64 is fixed to the lip 63 c of the stud body 63, the projecting member 64 is fixed to the outer surface of the flange 63 b of the stud body 63. It is possible to avoid fixing the finishing frame 52 and the wall heat insulating portion 38 and the like.

  In the intermediate runners 21 </ b> C and 21 </ b> D, the runner protrusion 71 is provided on the sash frame 41 side of the runner main body 73, so that the runner main body 73 is arranged in the wall height direction even when a load from the sash frame 41 is applied. Bending can be regulated by a runner protrusion 71 as a deflection regulating portion. Similarly, in the side stud 22B, since the stud protrusion 61 is provided on the sash frame 41 side of the stud body 63, even if a load from the sash frame 41 is applied, the stud body 63 in the wall width direction. Can be regulated by the stud protrusion 61 as a deflection regulating portion. Moreover, in addition to the runner main body 73 and the stud main body 63, the runner protrusion 71 and the stud protrusion 61 support the sash frame 41. Therefore, the fixing strength of the sash frame 41 with respect to the intermediate runners 21C and 21D and the side stud 22B. Can be increased. Therefore, in the outer wall part 11 having the window part 12, the sash frame 41 provided on the window part 12 can be suitably supported by the outer wall base 18.

  In the intermediate runners 21C and 21D, the runner main body 73 has a flange 73b extending in the wall height direction. Therefore, the runner main body 73 extends in the wall height direction by the flange 73b in addition to the runner protrusion 71. Deterrence against bending can be demonstrated. Moreover, since the runner protrusion 71 extends in the vertical direction from one of the pair of flanges 73b of the runner body 73, the runner protrusion 71 and the flange 73b individually have the bending restraining force added together. Can be demonstrated together. Thereby, it can suppress more reliably that intermediate runner 21C, 21D bends in a wall height direction.

  In the runner protruding portion 71, the intermediate runners 21C and 21D can be prevented from being bent in the wall thickness direction by the connecting plate portion 71b extending in the wall thickness direction. Therefore, the runner protrusion 71 can exert a deterring force against the deflection of the intermediate runners 21C and 21D in two directions. Moreover, since the runner projection 71 is formed in a rectangular cross section by the pair of projection plates 71a and the connecting plate 71b, the deflection suppressing force can be more effectively exhibited in two directions.

  Since the intermediate runners 21 </ b> C and 21 </ b> D are each formed by one member having a shape in which the runner protrusion 71 protrudes from the runner body 73, for example, the runner body 73 and the runner protrusion 71 are formed by separate members. Unlike the configuration, since it is not necessary to assemble the intermediate runners 21C and 21D, the work load at the construction site or factory can be reduced.

  In the side stud 22B, since the stud body 63 has a flange 63b extending in the wall width direction, the stud body in the wall width direction is also formed by the flange 63b in addition to the stud protrusion 61 (protruding member 64). It is possible to exert a deterrent against the bending of 63. Moreover, since the web 64a of the projecting member 64 extends in the wall width direction from one of the pair of flanges 63b of the stud body 63, the deflection suppressing force that the projecting member 64 and the flange 63b individually have added together. It can be brought out in a state. Thereby, it can suppress more reliably that the side stud 22B bends in a wall width direction.

  In the stud protrusion 61, the side stud 22B can be prevented from being bent in the wall thickness direction by the flange 64b extending in the wall thickness direction. Therefore, the stud protrusion 61 can exert a deterring force against the deflection of the side stud 22B in two directions.

  In the side stud 22 </ b> B, the projecting member 64 serves as a fixing target for the sash frame 41 and also serves as a reinforcing means for the stud main body 63. Therefore, the fixing target for the sash frame 41 and the reinforcing means for the stud main body 63. Compared with the case where these are separately added to the side stud 22B, the configuration of the side stud 22B can be simplified. The same applies to the intermediate runners 21 </ b> C and 21 </ b> D. The runner protrusion 71 is a fixing target of the sash frame 41 and also serves as a reinforcing means for the runner body 73. The configuration of the intermediate runners 21C and 21D can be simplified as compared with the case where the object and the reinforcing means of the runner body 73 are separately added to the intermediate runners 21C and 21D.

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

  (1) Although the protruding member 64 is fixed to the lip 63c of the stud main body 63 in the side stud 22B in the above embodiment, the protruding member 64 may be fixed to the flange 63b of the stud main body 63. For example, as shown in FIG. 8 (a), the stud main body 63 is formed in a U-shaped cross section by a lightweight grooved steel without a lip, and the protruding member 64 is a light angle steel (lightweight) having an L-shaped cross section. An angle material is used. The protruding member 64 has a first plate portion 81a and a second plate portion 81b that are orthogonal to each other, and one stud extends in the wall width direction and the other plate extends in the wall thickness direction. It is attached to the main body 63. Here, the first plate portion 81a extends in the wall width direction and the second plate portion 81b extends in the wall thickness direction.

  In the protruding member 64, the first plate portion 81 a is fixed to the flange 63 b on the indoor side of the stud body 63. In this case, with the outdoor side surface of the first plate portion 81a overlapped with the indoor side surface of the flange 63b, the overlapped portion is fixed by welding or the like. In the protruding member 64, the second plate portion 81b is disposed at a position spaced from the stud main body 63 toward the window portion 12, and the main frame body 51 of the sash frame 41 is screwed to the second plate portion 81b. It is fixed by.

  In the first plate portion 81a, the portion fixed to the stud main body 63 corresponds to the first fixed portion, and the portion extending in the wall width direction between the stud main body 63 and the second plate portion 81b is the extension portion. It corresponds to. Further, the second plate portion 81 b corresponds to a second fixing portion fixed to the sash frame 41. Further, the first plate portion 81a corresponds to a protruding plate portion protruding toward the sash frame 41, and the second plate portion 81b corresponds to an orthogonal plate portion orthogonal to the protruding plate portion.

  Therefore, even in the configuration in which the protruding member 64 is formed of light angle steel instead of lightweight grooved steel, in the stud protruding portion 61 formed by the protruding member 64, the side stud 22B has a wall width as in the above embodiment. The first plate portion 81a can suppress bending in the direction, and the second plate portion 81b can suppress the side stud 22B from bending in the wall thickness direction.

  Incidentally, in the side stud 22B, the width dimension (for example, 40 mm) of the flange 63b of the stud body 63 is larger than the width dimension (for example, 30 mm) of the first plate portion 81a of the protruding member 64 in the wall width direction. The width dimension (for example, 20 mm) in which the first plate portion 81a protrudes from the flange 63b of the stud body 63 is ½ of the width dimension of the flange 63b. In the protruding member 64, the extension dimension (for example, 30 mm) of the first plate part 81a from the second plate part 81b is the extension dimension (for example, 15 mm) of the second plate part 81b from the first plate part 81a. It has become twice.

  In the configuration in which the protruding member 64 is attached to the outer surface of the flange 63b of the stud body 63, the stud body 63 may be formed of a lightweight grooved steel with a lip having a lip 63c. In the configuration in which the stud main body 63 does not have the lip 63 c, the first plate portion 81 a of the protruding member 64 may be attached to the inner side surface instead of the outer side surface of the flange 63 b of the stud main body 63.

  (2) In the above embodiment, the stud protrusion 61 is formed by the protrusion member 64 in the side stud 22B, but the stud protrusion 61 is similar to the runner protrusion 71 in that part of the stud body 63 is a window. It may be formed by projecting toward the portion 12. For example, as shown in FIG. 8B, the side stud 22 </ b> B is configured by one steel material 82. In this configuration, the steel material 82 includes a web 82a, a pair of flanges 82b facing each other with the web 82a interposed therebetween, and a lip 82c extending from the tip of the flange 82b toward the groove opening side. .

  In the steel material 82, the extension dimension from the web 82a of the pair of flanges 82b is different, and the extension dimension of the indoor flange 82b is larger than that of the outdoor flange 82b. In the steel material 82, in the wall width direction, the portion on the opposite side of the sash frame 41 including the outdoor-side lip 82c (the right-side portion in FIG. 8B) forms the stud body 63, and the outdoor-side lip 82c is formed. A portion protruding from the lip 82c toward the sash frame 41 (the left portion in FIG. 8A) forms a stud protrusion 61.

  In the side stud 22B formed of the steel material 82, a portion of the indoor flange 82b that protrudes to the window 12 side from the outdoor lip 82c corresponds to the protruding plate portion, and the indoor lip 82c protrudes. It corresponds to an orthogonal plate portion orthogonal to the plate portion.

  Therefore, even in the configuration in which the side stud 22B is formed by one steel material 82 instead of two members, the side stud 22B bends in the wall width direction in the stud protrusion 61 as in the above embodiment. Can be suppressed by the indoor-side flange 82b, and the side-side stud 22B can be suppressed from bending in the wall thickness direction by the indoor-side lip 82c.

  (3) In the above embodiment, the stud main body 63 of the side stud 22B is provided with the groove portion facing the window portion 12, but the stud main body 63 is similar to the runner main body 73 of the intermediate runners 21C and 21D. The groove portion may be provided facing the side opposite to the window portion 12. For example, the outer surface of the web 63 a of the stud main body 63 is opposed to the outer peripheral surface of the main frame 51 of the sash frame 41, and the protruding member 64 is attached to the outer surface of the web 63 a of the stud main body 63. . Even in this configuration, the protruding member 64 forms the stud protruding portion 61 protruding from the stud main body 63 toward the window portion 12 side.

  (4) In the above embodiment, in the side stud 22B, the protruding member 64 is formed of channel steel. However, the protruding member 64 includes a first fixed portion fixed to the stud body 63, and a first fixed portion. If it has the extension part extended toward the window part 12 and the 2nd fixing | fixed part extended from the extension part and being fixed to the sash frame 41, the board | plate material extended in a wall width direction, or with a lip It may be formed of a channel steel, a rectangular cylindrical steel material, or the like.

In the protruding member 84, a lip is provided on the indoor flange, and no lip is provided on the outdoor flange. In this case, the outer surface of the lip is overlapped with the outer surface of the web 73a of the runner main body 73, and the contact area between the projecting member 84 and the runner main body 73 is larger than when the lip is not provided on the flange. It has become. For this reason, if the contact part of the protrusion member 84 and the runner main body 73 is connected by welding etc., the fixed strength of the protrusion member 84 with respect to the runner main body 73 can be raised.

  Further, in the intermediate runners 21 </ b> C and 21 </ b> D in which the runner protruding portion 71 is formed by the protruding member 84, the indoor flange of the protruding member 84 may be attached to the indoor side surface of the runner main body 73. For example, as shown in FIG. 11A, in the projecting member 84 of the lower intermediate runner 21D, the indoor flange has a larger projecting dimension from the web than the outdoor flange, and the indoor flange is The runner body 73 extends downward from the upper surface of the runner body 73, and the outdoor side surface of the flange overlaps the indoor side surface of the flange 73 b of the runner body 73. Even in this case, the projecting plate portion 71 a of the runner projecting portion 71 is formed by the flange of the projecting member 84, and the indoor projecting plate portion 71 a extends from the indoor side flange 73 b of the runner body 73 toward the window portion 12. Will be.

  Furthermore, in the connection part of the side stud 22B and the intermediate runners 21C and 21D, the runner protrusion 71 may overlap the intermediate runners 21C and 21D in the wall thickness direction. For example, as shown in FIG. 11 (b), in the lower intermediate runner 21D, the recess 78 is not formed in all the notches of the runner protrusion 71 in the wall thickness direction, but on the side studs 22B in the runner protrusion 71.
