This vertical resin cover material 347 partially covers the window sill 62 of the wall panel 10 that constitutes part of the building skeleton 1 from the indoor side.

[0023] The trim members 11, 12, 13 and the flashing member 14 are made of metal, aluminum in this embodiment, and are framed on all four sides. The trim member 11 and the flashing member 14 are aligned along the X-axis direction, and the trim members 12, 13 are aligned along the Y-axis direction. The trim member 11 is fastened to the upper frame 32 with screws 92 (fixing devices), the trim members 12, 13 are fastened to the left and right vertical frames 34 with screws 92, respectively, and the flashing member 14 is attached by engaging with the lower frame 33. The trim members 11, 12, 13 and the flashing member 14 separate the exterior wall material 8 at a position on the outdoor side of the inward-opening window 3.

[0024] The trim material 11 is disposed on the exterior side of the upper frame 32 in the Z-axis direction. The trim material 11 has a pair of upper and lower recessed pieces 111, 112, an exterior recessed piece 113 and an interior recessed piece 114 that connect the recessed pieces 111, 112, an intermediate piece 115 that is disposed between the exterior recessed piece 113 and the interior recessed piece 114 in the Z-axis direction and that connects to the recessed pieces 111, 112, and a fixed piece 116 that protrudes upward from the connecting portion of the upper recessed piece 111 and the interior recessed piece 114. The projection piece 111 is aligned along the Z-axis direction, and the portion outside the room beyond the position of the intermediate piece 115 is slightly inclined downward as it approaches the outside of the room. The projection piece 112 is formed along the Z-axis direction, and has an opening 117 formed along the X-axis direction at a position between the exterior projection piece 113 and the intermediate piece 115. The portion of the projection piece 112 that defines the opening 117 between the exterior projection piece 113 and the intermediate piece 115 is configured as a pair of hanging pieces 112A onto which a back plate 94, which will be described later, is hung. In addition, the projection piece 112 has a screw hole forming portion 112B formed between the intermediate piece 115 and the interior projection piece 114, onto which the trim members 12, 13 are screwed. The projection piece 111, the exterior projection piece 113, the intermediate piece 115, and the pair of hook pieces 112A form a dovetail groove 118 along the X-axis direction. The aforementioned hook pieces 112A are arranged on both edges of the opening 117 of the dovetail groove 118. The exterior projection piece 113 is formed with a protrusion 113A that protrudes toward the interior of the room, forming a recess between it and the hook piece 112A.

The fixing position of the fixing piece 116 relative to the upper exterior appearance surface 313 is located above the positions of the sealant 41 and the backup material 42. Therefore, even if the sealant 41 and the backup material 42 deteriorate over time and water such as rainwater seeps in, the water will not reach the fixing position located above the positions of the sealant 41 and the backup material 42, thereby improving watertightness.

[0025] The left and right trim members 12, 13 are formed from common extrusions and are arranged in opposite directions, so the following will explain in detail the structure of trim member 12, and the structure of trim member 13 will be appropriately designated with the same symbols as those used for trim member 12, and a detailed explanation of this structure will be omitted. The trim material 12 is disposed on the outdoor side of the vertical frame 34 in the Z-axis direction. The trim material 12 has a pair of left and right indentation pieces 121, 122 along the Z-axis direction, an outdoor indentation piece 123 and an indoor indentation piece 124 that connect the indentation pieces 121, 122, an intermediate piece 125 that is disposed between the outdoor indentation piece 123 and the indoor indentation piece 124 and connects to the indentation pieces 121, 122, and a fixed piece 126 that protrudes toward the inner periphery from the connecting portion of the outer periphery indentation piece 121 and the indoor indentation piece 124. The visible piece 122 has an opening 127 formed along the X-axis direction at a position between the exterior visible piece 123 and the intermediate piece 125. The portion of the visible piece 122 that defines the opening 127 between the exterior visible piece 123 and the intermediate piece 125 is configured as a pair of hanging pieces 122A on which a back plate 94 (described later) is hung. The recessed piece 121, the exterior recessed piece 123, the intermediate piece 125, and the pair of hook pieces 122A form a dovetail groove 128 along the Y-axis direction. The aforementioned hook pieces 122A are arranged on both edges of the opening 127 of the dovetail groove 128. The exterior recessed piece 123 is formed with a protrusion 123A (protrusion) that protrudes toward the outside of the room, forming a recess between the exterior recessed piece 123 and the hook piece 122A. In addition, the portion of the intermediate piece 115 on the recessed piece 122 side forms a recess that is recessed toward the inside of the room. Additionally, the front pieces 121 and 122, the intermediate piece 125, and the interior front piece 124 form a hollow portion 129 along the X-axis direction. The hollow portion 129 is disposed adjacent to the dovetail groove portion 128 on the interior side. The fixing piece 126 of this parting material 12 is fixed to the vertical exterior facing surface 343 of the vertical frame 34 with a screw 92, and the indoor end of the facing piece 122 abuts against the vertical exterior facing surface 343.

[0026] A bracket 15 is fixed to the above-mentioned trim 11 by a bolt 93 (fixing device) and a back plate 94, and brackets 16 and 17 are fixed to the above-mentioned trims 12 and 13 by bolts 93 and back plates 94, respectively. As shown in Fig. 6(A), the bracket 15 has a one-sided visible portion 151 and a one-sided recessed portion 152 and is formed with an L-shaped cross section. The visible portion 151 has two holes 151A through which screws 91 for fixing the mounting bracket 541 of the roll curtain unit 50 are inserted. The recessed portion 152 has one hole 152A through which a bolt 93 for fixing to the parting material 11 is inserted. The hole 152A is provided in the recessed portion 152 at a position closer to the visible portion 151 side. This bracket 15 is used as shown in Figure 4. The recessed portion 152 is arranged along the Z-axis direction, and the visible portion 151 is arranged rising upward along the Y-axis direction from the outdoor end of the recessed portion 152. A bolt 93 is inserted into the hole 152A of the recessed portion 152, and this bolt 93 is threadedly fastened to the back plate 94 that is arranged in the dovetail groove portion 118 and hung on the hanging piece portion 112A, thereby attaching the bracket 15 to the parting material 11. The recessed portion 152 is formed to extend toward the interior of the room beyond its fixed position relative to the parting material 11, and this extended portion (part of the bracket 15) is arranged along the recessed piece portion 112 of the parting material 11 and is arranged in a position adjacent to the hollow portion 119 in the Y-axis direction, thereby increasing the attachment strength of the bracket 15 to the parting material 11. The sighting portion 151 is disposed at a position that protrudes toward the outside of the room relative to the parting material 11 in the Z-axis direction, and is fixed to a mounting bracket 541 in the main body box portion 54 of the roll curtain unit 50 with a screw 91. This sighting portion 151 is configured as a fixing portion to which the roll curtain unit 50 is fixed.

[0027] Brackets 16 and 17 have the same configuration and are arranged in opposite left-right directions as shown in FIG. 3. Therefore, the configuration of bracket 16 will be described in detail below, and the configuration of bracket 17 will be appropriately designated with the same reference numerals as those of bracket 16, and detailed description thereof will be omitted. As shown in Figure 6 (B), the bracket 16 has a piece-shaped visible portion 161, a piece-shaped recessed portion 162 continuous with one end of the visible portion 161, and a piece-shaped abutting portion 163 continuous with the other end of the visible portion 161. The visible portion 161 has two holes 161A formed therein through which screws 91 for fixing the hanging member 55 are inserted. The recessed portion 162 has three holes 162A formed therein through which bolts 93 used for fixing to the parting material 12 are inserted. The abutting portion 163 extends from the visible portion 161 in a bent manner and is formed shorter than the recessed portion 162. This bracket 16 is used as shown in Fig. 5. The projection portion 162 is arranged along the Z-axis direction, the sight portion 161 is arranged extending in the X-axis direction from the outdoor end of the projection portion 162 toward the outer periphery, and the abutment portion 163 is arranged along the Z-axis direction from the sight portion 161 toward the indoor side and is located at a position closer to the outer periphery than the projection portion 162. A bolt 93 is inserted into the hole 162A of the recessed portion 162, and this bolt 93 is disposed in the dovetail groove portion 128 and screwed into the back plate 94 that is hung on the hanging piece portion 122A, thereby attaching the bracket 16 to the parting material 12. The recessed portion 161 is disposed in a position that protrudes toward the exterior of the room relative to the parting material 12 in the Z-axis direction, and the hanging member 55 of the roller curtain unit 50 is fixed thereto with a screw 91. This recessed portion 161 is configured as a fixing portion to which the roller curtain unit 50 is fixed. The indoor end of the abutting portion 163 abuts against the exterior recessed piece portion 123 of the parting material 12, increasing the attachment strength of the bracket 16 to the parting material 12.

[0028] In the wall panel 10 of this embodiment, an external component mounting structure 100 is configured in which an external component, a roll curtain unit 50, is attached to the trim members 11, 12, and 13 via the aforementioned brackets 15, 16, and 17 at a position protruding outside the room beyond the trim members 11, 12, and 13. According to the mounting structure 100 for external components, by attaching the trim members 11, 12, 13 to the window frame 31, even if rainwater seeps into the mounting portion, it can be drained through the window frame 31, so that the number of locations requiring waterproofing treatment can be reduced, and the effort required for waterproofing can be reduced, compared to, for example, when attaching the trim members 11, 12, 13 to the building skeleton 1. Since the sighting portions 151, 161, which are the fixing portions of the brackets 15, 16, 17, are positioned in positions that protrude further toward the outside than the trim members 11, 12, 13, the main body box portion 54 of the roller curtain unit 50 can be positioned in a less noticeable position when viewed from the inside to the outside through the opening 5 in the building skeleton 1, and the view can be maintained even when the roller curtain unit 50 is mounted. Since the roll curtain unit 50 is fixed to the sight portions 151, 161 of the brackets 15, 16, 17 mentioned above, there is no need for the vertical dimensions (height dimensions) and horizontal dimensions (width dimensions) of the roll curtain unit 50 to fit within the dimensions of the space partitioned by the trim materials 11, 12, 13, eliminating dimensional restrictions on the roll curtain unit 50, and by increasing the dimensions of the roll curtain unit 50, the area covered around the opening 5 in the building structure 1 can be increased. Furthermore, by placing the back plate 94 in the dovetail groove portions 118, 128 and hanging it on the hanging pieces 112A, 122A, and then fixing the brackets 15, 16, 17 to which the roll curtain unit 50 is fixed to this back plate 94 with screws 91, the roll curtain unit 50 can be easily attached to the parting materials 11, 12, 13. By forming hollow portions 119, 129 in the parting materials 11, 12, 13, the strength of the parting materials 11, 12, 13 themselves can be improved, and the attachment strength of the roll curtain unit 50 attached via the brackets 15, 16, 17 to the back plate 94 placed in the dovetail groove portions 118, 128 can also be improved. Furthermore, even if a rotational moment occurs in the brackets 15, 16, 17 to which the roll curtain unit 50 is fixed to the sighting portions 151, 161 at a position protruding outside the room beyond the parting materials 11, 12, 13, a portion of the brackets 15, 16, 17 adjacent to the aforementioned hollow portions 119, 129 is supported by the parting materials 11, 12, 13, thereby improving the mounting strength of the roll curtain unit 50.

[0029] [Variations] In the above embodiment, the brackets 15, 16, and 17 are fixed to the parting strips 11, 12, and 13 using the bolts 93 and the back plate 94, but this is not limited to this. For example, if the brackets 15, 16, and 17 can be fixed with sufficient mounting strength without using the back plate 94, the back plate 94, the dovetail grooves 118 and 128, and the openings 117 and 127 may be omitted. In the above embodiment, the parting materials 11, 12, 13 are formed with the hollow portions 119, 129, but this is not limited to this. For example, if the parting materials 11, 12, 13 can be configured with sufficient strength without forming the hollow portions 119, 129, the hollow portions 119, 129 may be omitted. In the above embodiment, the part of bracket 15 that extends to a position on the indoor side of the fixing position to parting material 11 is not fixed to parting material 11 at a position adjacent to hollow portion 119, but may be fixed at that position by a fixing device. In this case, the attachment strength of bracket 15 to parting material 11 can be further improved. In the above embodiment, a portion of the projection portion 152 of the bracket 15 extends to a position inside the room that is further inside the room than the fixed position relative to the trim material 11, and this portion is positioned adjacent to the trim material 11 in the Z-axis direction, but this is not limited to this. As long as the mounting strength of the bracket 15 to the trim material 11 is sufficient, it may be positioned at a position away from the position adjacent to the hollow portion 119 in the Z-axis direction, and the portion of the bracket 15 that extends to a position inside the room that is further inside the room than the fixed position relative to the trim material 11 may be formed shorter. In the above embodiment, the upper frame 32 has a recess 316, but the recess 316 may be omitted. Even in this case, the fixing position where the fixing piece 116 of the parting material 11 is fixed to the upper exterior appearance surface 313 of the upper frame 32 is located above the positions of the sealing material 41 and the backup material 42 between the exterior wall material 8 and the parting material 11. Therefore, even if water such as rainwater seeps into the room due to deterioration of the sealing material 41 and the backup material 42 over time, the water can be prevented from seeping into the room from the fixing position of the parting material 11 and the upper frame 32, which is located higher than the sealing material 41 and the backup material 42. In the above embodiment, the fixing positions of the parting material 11 and the upper frame 32 are disposed above the positions of the sealing material 41 and the backup material 42, but this is not limited to this. For example, in cases where a sufficient waterproofing treatment has been applied to the fixing positions, where there is no need to consider deterioration of the sealing material 41 and the backup material 42 over a predetermined period of time, or where the fixing structure of the parting material 11 and the upper frame 32 is configured to prevent water penetration, the fixing positions of the parting material 11 and the upper frame 32 may be disposed at a height equivalent to or lower than the positions of the sealing material 41 and the backup material 42. In the above embodiment, bracket 15 is formed with an L-shaped cross section having a sighting portion 151 and a projection portion 152, and bracket 16 (17) is formed with a sighting portion 161, a projection portion 162 and an abutment portion 163, but these shapes are not limited to these as long as external parts such as a roll curtain unit 50 can be placed in a predetermined position and attached to the trim materials 11, 12, 13. In the above embodiment, the roll curtain unit 50, which is one type of sunshade unit, has been described as an external planar component, but other components such as a louver unit, a surface grille unit, and a shutter unit may also be used.

[0030] Fig. 7 shows, as a first modified example, a wall panel 10B equipped with a plurality of rotatable louver blades 71 as external components of a louver unit 70 arranged in a row above and below a frame body 72, instead of the above-mentioned roller curtain unit 50. Fig. 7(A) is a vertical cross-sectional view, and Fig. 7(B) is a horizontal cross-sectional view. In this case, the louver unit 70 is not attached to the trim 11 via the bracket 15, and the frame body 72 of the louver unit 70 is attached to the trim 12, 13 via brackets 16B, 17B instead of brackets 16, 17. Brackets 16B, 17B are formed identically and are arranged in opposite left-right directions. These brackets 16B, 17B have a visible portion 161 and a recessed portion 162 and are formed with an L-shaped cross section. The visible portion 161 is continuous with the outdoor end of the recessed portion 162 and extends inward in the X-axis direction. The recessed portion 162 of brackets 16B, 17B is bolted to the parting materials 12, 13, similar to the recessed portion 162 of bracket 16 described above. Furthermore, the visible portion 161 is bolted to the frame body 72 using bolts 93 and a back plate 94. The louver unit 70 attached to the parting members 12, 13 in this manner is disposed at a position that protrudes further toward the exterior side than the parting members 12, 13.

[0031] Figure 8 shows, as a second modified example, a wall panel 10C that includes a surface grille 80 as an external component instead of the above-mentioned roll curtain unit 50. Figure 8(A) is a vertical cross-sectional view, and Figure 8(B) is a horizontal cross-sectional view. In this case, the grille 80 is not attached to the trim 11 via bracket 15, but is attached to the trim 12, 13 via brackets 16B, 17B instead of brackets 16, 17. The configuration and arrangement of brackets 16B, 17B are the same as those described above in the first modified example. The recessed portions 162 of brackets 16B, 17B are bolted to the trim 12, 13, similar to the recessed portion 162 of bracket 16 described above in this embodiment. In addition, the recessed portion 161 is bolted to the grille 80 using bolts 93 and a back plate 94.

[0032] [Summary of the invention] (1) The mounting structure for an external part of the present invention is a mounting structure for an external part in which an external part is mounted to a trim material that is positioned further outside the room than a frame body that is installed in an opening in a building's main body, and is characterized in that the trim material is attached to the frame body, and a bracket having a fixing portion to which the external part is fixed is attached to the trim material, and the fixing portion is positioned in a position that protrudes further outside the room than the trim material. According to the mounting structure for external components of the present invention, by attaching the trim material to the frame body, even if rainwater infiltrates the mounting portion, it can be drained through the frame body. Therefore, compared to when the trim material is attached to the building frame, the number of places where water-stopping treatment is required can be reduced, thereby reducing the effort required for the water-stopping treatment. Furthermore, since the fixing part of the bracket is positioned at a position that protrudes further to the outside of the room than the trim, the main box part of the external component can be positioned in a position that is less noticeable when looking from the inside to the outside through an opening in the building frame, and visibility can be maintained even when external components are installed. Furthermore, because the external component is fixed to the fixing portion of the bracket, there is no need for the vertical (height) or horizontal (width) dimensions of the external component to fit within the dimensions of the space partitioned by the parting material, eliminating dimensional restrictions on the external component. In particular, if the external component is a sunshade unit or louver unit, increasing the dimensions of these units can increase the area covered around the opening in the building frame. (2) In the mounting structure for an external component of the present invention, the parting strip may have dovetail grooves on which hook pieces for hanging the backing plate are disposed on both edges of the opening. With this configuration, the back plate is placed in the dovetail groove portion and hung on the hook portion, and the bracket to which the external component is fixed is fixed to this back plate with a fastener such as a screw, thereby making it possible to easily attach the external component to the parting material. (3) In the mounting structure for an external component of the present invention, the parting member may have a hollow portion disposed adjacent to the dovetail groove portion on the indoor side. With this configuration, the formation of the hollow portion described above not only improves the strength of the parting material itself, but also improves the mounting strength of external components attached via brackets to the back plate placed in the dovetail groove portion. (4) In the mounting structure for an external component of the present invention, the bracket may be formed to extend toward the interior of the vehicle beyond the fixed position relative to the trim, and a portion of the bracket may be positioned adjacent to the hollow portion. With this configuration, even if a rotational moment occurs in the bracket to which the external part is fixed to the fixing part at a position protruding outside the room beyond the trim, the part of the bracket adjacent to the hollow part mentioned above is supported by the trim, thereby improving the mounting strength of the external part. (5) In the mounting structure for an external component of the present invention, a portion of the bracket may be fixed to the parting member by a fastener at a position adjacent to the hollow portion. According to this configuration, by fixing a part of the bracket to the parting material with a fixing tool at a position adjacent to the hollow portion, the mounting strength of the external component can be further improved. (6) In the mounting structure for external components of the present invention, the frame body comprises a metal frame material on the outdoor side that is placed in the opening, and a frame material having a resin cover material on the indoor side that is connected to the metal frame material and covers a part of the building body, and the trim material may be fixed to the outdoor visible surface portion of the metal frame material. With this configuration, the trim can be easily fixed to the exterior visible surface of the metal frame material, and since the trim is fixed to the metal frame material, external parts can be firmly attached to the frame body via the bracket and trim material. (7) In the mounting structure for external components of the present invention, an exterior wall material is provided on the outdoor side of the building structure, the frame body has an upper frame as the frame material, a sealing material is provided between the exterior wall material and the trim material, the trim material has a fixing piece portion that protrudes upward and is fixed to the outdoor visible surface portion, and the fixing position of the fixing piece portion relative to the outdoor visible surface portion may be positioned above the position of the sealing material. With this configuration, the fixing position between the fixing piece of the trim material and the exterior visible surface of the upper frame is positioned above the position of the sealing material, so even if the sealing material deteriorates over time and becomes more susceptible to the infiltration of water such as rainwater, the risk of water infiltrating into the interior of the room beyond the exterior visible surface of the upper frame can be reduced. (8) In the mounting structure for external components of the present invention, the frame body has an upper frame as the frame material, and the upper frame forms a recess in the metal frame material that opens upward and has a portion defined as the exterior visible surface, and the connection position between the metal frame material and the resin cover material may be located on the interior side of the recess. With this configuration, even if water such as rainwater gets into the recess, it can be drained through the frame body, and furthermore, since the connection position between the metal frame material and the resin cover material is located on the indoor side rather than the recess, the risk of water leaking into the indoor side from the connection part between the metal frame material and the resin cover material is reduced. (9) The wall panel of the present invention is a wall panel having a panel body that constitutes the wall portion of a building structure and an opening frame that forms an opening in which a frame body is installed, characterized in that a trim material is placed at a position outside the frame body, and the above-mentioned mounting structure for external parts of the present invention is configured to attach external parts to the trim material. According to the wall panel of the present invention, a wall panel can be configured that can achieve the same effects as those of the present invention described above. [Explanation of symbols]
