The panel body 1 disposed above the fixed window 2 is disposed with the protrusion 1 d provided on the lower side placed on the upper surface of the upper side 214 b of the reinforcing metal fitting 214 .
Between the upper frame 21 and the panel body 1, a backup material u11 is arranged between the lower side edge 214c of the auxiliary bracket 214 and the upper surface of the upper frame 21, and a sealing material s14 is filled between the lower side edge 214c of the auxiliary bracket 214 and the upper surface of the panel body 1 and the upper frame 21 on the outdoor side of the backup material u11.
A drainage path W3 is formed between the outer peripheral surface of the upper frame 21 and the mounting auxiliary material 213 and auxiliary metal fittings 214 to drain rainwater and the like that has infiltrated into the indoor side of the panel body 1.

(Connection between the bottom edge of the fixed window and the top edge of the panel body: cross section ee of Figure 1)
As shown in Figures 2 and 6, the bottom frame 22 of the fixed window 2 has a flange 22b attached to its inner periphery on the outside of the room to form a panel opening 22a, and the glass 25 etc. are held in place via an airtight material.

A mounting bracket 222 is attached to the lower position of the interior side surface of the lower frame 22, and the mounting bracket 222 fits into an angle member B fixed to a cross member A3 of the building structure.
The lower frame 22 has support bolts 223 on its outer circumferential surface (lower surface) and is supported on the upper surface of the cross member A3 via the support bolts 223.

The lower frame 22 has an attachment auxiliary member 224 having an approximately L-shaped cross section and a positioning member 225 fixed to its underside.
The positioning member 225 is a member with an approximately L-shaped cross section and is attached to the indoor side underside of the lower frame 22, and the part extending downward from the underside of the lower frame 22 abuts the indoor side end of the mounting auxiliary material 224 to position the mounting auxiliary material 224.

One side of the L-shape of the mounting support member 224 (the visible wall portion 224a) is fixed to the underside of the bottom frame 22 with a screw b21, and the other side of the L-shape (the visible wall portion 224b) is fixed to the exterior side of the horizontal member A3 with a screw b22, sealing the gap between the bottom frame 22 and the horizontal member A3.

The outside of the space between the mounting auxiliary material 224 and the underside of the lower frame 22 is filled with a sealing material s21 that seals the gap between them, and a sealing tape s22 is attached to the outside surface of the visible wall portion 224b of the mounting auxiliary material 224 to seal the space between it and the panel body 1.

The panel body 1, which is placed below the fixed window 2, is placed against the exterior side of the visible wall portion 224b of the mounting support material 224, sandwiching the sealing tape s22 between them, and is fixed to the horizontal member A3 by the fixing means b1.

A water drip member 226 is provided below the fixed window 2 so as to cover the upper end portion of the panel body 1 fixed to the horizontal member A3.
The drainage member 226 is made of the same metal material as the surface material 12 of the panel body 1, and has a fixing portion 226a fixed to the mounting auxiliary material 224, a top plate portion 226b that descends from the lower end of the fixing portion 226a toward the outside of the room, and an outside portion 226c that extends downward from the outside end of the top plate portion 226b.

The drainage member 226 is attached between the lower frame 22 and the upper end of the panel body 1 by having the fixing portion 226a fixed to the upper portion of the visible wall portion 224b of the mounting auxiliary material 224 with a screw b23.
The drainage member 226 attached to the mounting auxiliary material 224 has a top plate portion 226b covering the upper surface of the panel body 1 and an outdoor side portion 226c covering the outdoor side of the surface material 12 so as to fit into the mounting portion 1a of the panel body 1, and the outdoor side portion 226c of the drainage member 226 and the outdoor side of the surface material 12 are flush with each other.

(Connection between the vertical side of the fixed window and the vertical side of the panel body: cross section ff in Figure 1)
As shown in Figures 3 and 7, the vertical frame 23 of the fixed window 2 has a flange 23b attached to its inner periphery on the outside of the room to form a panel opening 23a, and the glass 25 etc. are held in place via an airtight material.
The vertical frame 23 is fixed by screws b31 to an angle member B whose inside end is fixed to a vertical member A2 of the building frame.

The vertical frame 23 has an attachment auxiliary material 232 fixed to its outer circumferential surface.
The mounting auxiliary material 232 has a projected wall portion 232a, a visible wall portion 232b extending at a right angle from one side of the projected wall portion 232a, a protrusion 232c extending in the anti-projected wall portion direction from the surface of the anti-projected edge side of the visible wall portion 232b, and an airtight material retaining portion 232d adjacent to the protrusion 232c and facing in the same direction as the protrusion 232c.

The mounting auxiliary material 232 is arranged between the vertical frame 23 and the vertical member A2 so that the protruding portion 232c protrudes to the outside of the room, the projecting wall portion 232a is fixed to the outer peripheral surface of the vertical frame 23 with screws b32, the projecting wall portion 232b is fixed to the outside surface of the vertical member A2 with screws b33, and the frame side airtight material s33 is held by the airtight material holding portion 232d.

The outdoor portion between the mounting auxiliary material 232 and the outer peripheral surface of the vertical frame 23 is filled with a sealing material s31 that creates an airtight seal between the two, and a sealing tape s32 that seals between the mounting auxiliary material 232 and the vertical member A2 is attached to the end of the visible wall portion 232b of the mounting auxiliary material 232.

The panel body 1 arranged adjacent to the fixed window 2 has its vertical side portion fixed to the vertical member A2 by a fixing means b1.
When the panel body 1 is fixed to the vertical member A2, the panel side airtight material s1 abuts against the protrusion 232c of the mounting auxiliary material 232, and the frame side airtight material s33 attached to the mounting auxiliary material 232 abuts against the outer periphery 12b of the surface material 12 of the panel body 1.

Back-up material u31 is placed between the surface material 12 of the panel body 1 fixed to the vertical member A2 and the vertical frame 23 of the fixed window 2, and sealing material s34 is filled in between. A drainage path W2 is formed between the outer periphery of the vertical frame 23 and the mounting auxiliary material 232 to drain rainwater and other water that has infiltrated into the interior of the panel body 1.

As shown in FIG. 12(b), the drainage path W2 formed between the outer periphery of the vertical frame 23 and the mounting support material 232 (and the drainage path formed between the vertical frames 23 of the fixed windows 2, 2 shown in FIG. 3) is filled with a sealant s below it, and a drainage part W4 is arranged to discharge water that has traveled down the drainage path W2 to the outside of the room.

(Connection of drainage route at upper corner of fixed window)
In the exterior wall of this embodiment, a drainage path W1 at the connection part where the panel bodies 1, 1 are adjacent to each other on the left and right, and a drainage path W2 at the connection part where the panel body 1 and the fixed window 2 are adjacent to each other on the left and right are formed side by side in an up and down manner at the upper corner of the fixed window 2.

In the case of an exterior wall where the connection parts of adjacent panel bodies 1, 1 are vertically continuous, the drainage path W1 between the panel bodies 1, 1 can be connected vertically relatively smoothly. However, in areas such as the upper corners of the fixed window 2 where the connection parts of adjacent panel bodies 1 and fixed window 2 are located below the connection parts of adjacent panel bodies 1, 1, the configurations of the drainage paths arranged above and below are different, so it is necessary to smoothly connect the upper drainage path W1 and the lower drainage path W2.

The following describes a configuration for smoothly connecting the upper drainage path W1 and the lower drainage path W2 in an upper corner of a fixed window 2 where a connection part between a panel body 1 and a fixed window 2 adjacent to each other is located below a connection part between adjacent panel bodies 1, 1 to the left and right.

Above the upper corners of the fixed window 2, the vertical sides of the left and right panel bodies 1, 1 of the exterior wall are supported by the vertical members A1 of the building frame (Fig. 4), and below the upper corners of the fixed window 2, the vertical sides of the panel body 1 and the vertical frame 23 of the fixed window 2 are supported by the vertical members A2, and the upper frame 21 of the fixed window 2 is supported by the horizontal members A3 (Figs. 5 and 6).

As shown in Figures 8 and 9, at the upper corner of the fixed window 2, the vertical member A1 supporting the panel bodies 1, 1 located above the upper corner, and the vertical member A2 supporting the panel body 1 and the fixed window 2 located below the upper corner are connected via a horizontal member A3.

Below the upper corner of the fixed window 2, the fixed window 2 which is aligned with the panel body 1 has an installation auxiliary material 213 attached to the upper surface of the upper frame 21 and an installation auxiliary material 232 attached to the outer peripheral surface of the vertical frame 23, and at the upper corner, the end face of the upper frame 21 is butted against the inner peripheral surface of the vertical frame 23 to connect them.
In addition, the vertical frame 23 has appropriate cutouts in portions that interfere with the abutment of the end face of the upper frame 21 when connecting the upper frame 21.

As shown in Figures 8, 9 and 11, the mounting auxiliary material 232 of the vertical frame 23 has a visible wall portion 232b and a protruding portion 232c that extend upward beyond the upper end of the vertical frame 23.
The mounting auxiliary material 232 of the vertical frame 23 has the airtight material holding portion 232d cut out at a height position approximately the same as the upper end of the vertical frame 23, and the frame side airtight material s33 is not held by the airtight material holding portion 232d in the portion above the upper end of the vertical frame 23.

The mounting support material 213 of the upper frame 21 is fixed to the upper frame 21 so that it protrudes outward beyond the left and right ends of the upper frame 21.

When the vertical frame 23 and the upper frame 21 are connected, as shown in Figures 8 and 11, the end face of the upper frame 21 is butted against the inner peripheral surface of the vertical frame 23, and the upwardly extended portion of the visible wall portion 232b of the mounting auxiliary material 232 of the vertical frame 23 and the visible wall portion 213b of the mounting auxiliary material 213 of the upper frame 21 are butted together so that they are flush with each other, and the fixed window 2 is fixed to the vertical member A2 and the horizontal member A3.

The vertical member A1 at the connection where the panel bodies 1, 1 are adjacent to each other on the left and right has a scrap board 52 and a U-shaped member 5 arranged on the exterior side. At the upper corner of the fixed window 2, the scrap board 52 reaches a position lower than the lower edge of the horizontal member A3 whose lower end is connected to the lower part of the vertical member A1, as shown in FIG. 8, and overlaps the upper part of the visible wall portion 213b of the mounting auxiliary member 213 of the upper frame 21 of the fixed window 2 and the visible wall portion 232b of the mounting auxiliary member 232 of the vertical frame 23.

As shown in FIG. 9, the scrap board 52 has a notch 52a formed from the lower edge upward to match the protruding portion 232c of the mounting auxiliary material 213 of the upper frame 21, preventing interference with the protruding portion 232c when overlapping the visible wall portion 232b of the mounting auxiliary material 232 of the vertical frame 23. The scrap board 52 is positioned so that it fits into the interior side of the upper end of the frame side airtight material s33 and is fixed to the vertical member A1.

As shown in Figure 11 (a), the waste board 52 fixed to the vertical member A1 has sealing material S51 applied to the lower end portion of the waste board 52, the joint portion between the waste board 52 and the protruding portion 232c of the mounting auxiliary material 232, and the joint portion between the waste board 52 and the upper frame 21.
The sealing material s51 is continuous with the sealing material s11 between the upper frame 21 and the mounting auxiliary material 213 and the sealing material s31 between the vertical frame 23 and the mounting auxiliary material 232, and is subjected to a sealing treatment in the lower part of the scrap board 52. Note that the sealing tape s3 provided on the scrap board 52 is preferably attached after the sealing treatment with the sealing material s51 has been performed.

The U-shaped member 5 is disposed on the outdoor side of a temporary frame 52 that has been sealed with a sealing material s51.
At the upper corner of the fixed window 2, as shown in Figure 8, the lower end of the U-shaped member 5 extends downward below the lower edge of the horizontal member A3 to a position where it overlaps with the mounting auxiliary member 232 of the vertical frame 23 and the mounting auxiliary member 213 of the upper frame 21.
The U-shaped member 5 is positioned so that the side wall portion 5b, 5b farthest from the fixed window 2 abuts the surface of the fixed window 2 side of the protrusion 232c of the mounting auxiliary material 232, and the bottom wall portion 5a extends into the indoor side of the frame side airtight material s33.

As shown in Figures 10 and 11, in the overlapping portion between the mounting auxiliary material 232 of the vertical frame 23 and the U-shaped member 5, a sealant s52 is applied to cover the edge of the frame-side airtight material s33 at the joint between the frame-side airtight material s33 and the U-shaped member 5, and the upper corners of the fixed window 2 are sealed.

As described above, as shown in Figures 8 and 11, the exterior wall is arranged so that the lower end of the U-shaped member 5 located above the upper corner of the FIX window 2 overlaps with the mounting auxiliary material 232 and frame side airtight material s33 of the vertical frame 23 of the FIX window 2, which are located below the upper corner of the FIX window 2, so that the drainage paths W1, W2 formed above and below are smoothly continuous.
In addition, by providing a gap between the lower end of the U-shaped member 5 and the upper surface of the upper frame 21, the outer wall allows the drainage path W3 on the upper surface of the upper frame 21 to be continuous with the drainage path W2 below.

-Effects of the exterior wall of this embodiment-
In the exterior wall of this embodiment, the mounting auxiliary material for attaching the window to the building structure is provided with a protrusion that abuts the panel-side airtight material provided on the panel body, and the mounting auxiliary material for attaching the window to the building structure is provided with a frame-side airtight material that abuts the surface material of the panel body.Therefore, airtightness can be achieved between the panel body and the fixed window without using a separate material for airtightness, making construction easy.

The panel body 1 adjacent to the fixed window 2 can achieve high airtightness by providing airtightness between the panel side airtight material s1 provided on the vertical side of the panel body 1 and the protruding portion 232c of the mounting auxiliary material 232 of the fixed window 2, and between the frame side airtight material s33 provided on the mounting auxiliary material 232 and the surface material 12 of the panel body 1, which are adjacent to each other.

In addition, the exterior wall of this embodiment overlaps the U-shaped member that forms the drainage path W1 between adjacent panel bodies on the left and right, and the mounting auxiliary material and frame side airtight material that form the drainage path W2 in the area where the panel body and the window are adjacent on the left and right.By using a separate member to connect the drainage paths, the connection from the drainage path W1 between adjacent panel bodies on the left and right to the drainage path W2 in the area where the panel body and the window are adjacent on the left and right can be smoothly established, and water such as rainwater that has entered the indoor side of the panel body can be reliably drained without complicating construction.
In addition, the drainage path W3 passing through the upper surface of the upper frame 21 of the fixed window 2 is continuous with the drainage path W2, so that water in the drainage path W3 can be drained smoothly.

In addition, by attaching the drainage member to the mounting aid used to attach the bottom frame of the fixed window, which is located above the panel body, to the building frame, the installation of the drainage member is made easier, and by using the same metal material for the drainage member as the surface material of the panel body, a natural appearance can be created without adding any complicated processes, and an exterior wall with excellent design can be provided.

-Other embodiments-
The window to be attached to the exterior wall is not limited to a continuous window consisting of two fixed windows, but may be a single fixed window or a casement window such as an outward opening window.
It goes without saying that the above-described embodiments do not limit the invention described in the claims, but are to be treated as examples.
