[0019] A structural plywood 110 is attached to the outdoor side X1 of the building skeleton 100, and a plurality of furring strips 120 used to install the exterior wall materials 61, 63, 64 are attached to the outdoor side X1 surface of the structural plywood 110 on the outer periphery of the door frame 2. The furring strips 120 are formed in the shape of a plate having a predetermined width and a thickness in the projection direction, and extend in the horizontal or vertical direction.

[0020] The door frame 2 will now be described. As shown in Fig. 2, the upper frame 21 is fixed to the surface of the exterior side X1 of the building skeleton 100 on the opening 101 side of the structural plywood 110 arranged on the exterior side X1 of the building skeleton 100. The upper frame 21 includes an interior frame 211, an exterior frame 212, and bridge members 213a and 213b.

[0021] The indoor frame 211 is disposed on the indoor side X2 of the upper frame 21, and is formed in a U-shaped frame that opens upward in a vertical cross section. The indoor frame 211 is provided with an airtight material mounting portion 211a that extends inward from its inner peripheral surface in the viewing direction, and an airtight material 211b attached to the outdoor side X1 of the airtight material mounting portion 211a. This airtight material 211b supports the door body 3 without damaging it, and ensures the airtightness of the door body 3.

[0022] The outdoor frame 212 is arranged on the outdoor side X1 of the upper frame 21, and is arranged away from the indoor frame 211 on the outdoor side X1, and is connected to the indoor frame 211 by bridge members 213a and 213b.

[0023] The bridge members 213a and 213b are disposed between the indoor frame 211 and the outdoor frame 212, and connect the indoor frame 211 and the outdoor frame 212. The bridge members 213a and 213b are formed from a material with thermal insulation properties. The bridge members 213a and 213b connect the indoor frame 211 and the outdoor frame 212 while they are spaced apart from each other. This provides the upper frame 21 with an excellent thermal insulation structure (thermal insulation function). The bridge members 213a and 213b are made from a material with low thermal conductivity, such as resin or rubber.

[0024] The outdoor frame 212 has a hollow frame 2121 having a rectangular hollow portion 2121a extending in the projection direction in a vertical cross section, a protrusion 2122 protruding from the lower end of the outdoor side X1 end of the hollow frame 2121 toward the outdoor side X1, an L-shaped convex portion 2123 formed continuously with the upper part of the protrusion 2122 at the outdoor side X1 end of the hollow frame 2121 and protruding in an L shape toward the outdoor side X1, and an L-shaped piece 2124 formed at the upper end of the indoor side X2 end of the hollow frame 2121. The hollow portion 2121a extends in the left-right direction in which the upper frame 21 extends.

[0025] The indoor side X2 surface of the exterior building material 61 is arranged on the outdoor side X1 surface of the vertically extending plate portion 2121b that extends in the vertical direction at the upper side of the end portion on the outdoor side X1 of the hollow frame 2121. The vertically extending plate portion 2121b forms a backup portion that is arranged along the back surface of the indoor side X2 of the exterior building material 61.

[0026] The exterior wall material 61 is composed of, for example, a panel with tiles 61b attached to the exterior side X1 of a ceramic siding base material 61a. The ceramic siding base material 61a and the tiles 61b are fixed with adhesive 61c. The exterior wall material 61 is attached to the exterior side X1 of the furring strip 120 around the door frame 2.

The exterior wall material 61 is positioned to the side of the protrusion 2122 above the projection direction. The surface color of the exterior side X1 of the door main body 3 and the sub-door 4 and the surface color of the exterior wall material 61 are the same color or a color of the same color family.

[0027] The protrusion 2122 is formed on the visible surface of the outside side X1 of the upper frame 21 and protrudes toward the outside side X1. The protrusion 2122 is arranged laterally on the lower side of the exterior wall material 61. The protrusion 2122 is formed to protrude toward the outside side X1 from the lower end of the visible surface of the end of the outside side X1 of the hollow frame 2121, and protrudes in the projection direction to the position of the surface of the outside side X1 of the exterior wall material 61. The protrusion 2122 protrudes from the visible surface of the outside side X1 of the upper frame 21 toward the outside side X1 by a length in the projection direction that is the same as the thickness of the exterior wall material 61.

[0028] The protrusion 2122 has a protruding frame portion 2122a formed with a width in the vertical direction and protruding toward the outside X1 from the lower end of the end portion on the outside X1 side of the hollow frame 2121, and an airtight material arrangement frame 2122b protruding toward the outside X1 from the protruding frame portion 2122a with the same width as the protruding frame portion 2122a. The airtight material arrangement frame 2122b is formed in a C-shaped frame that opens downward. The airtight material 212a is arranged in the airtight material arrangement frame 2122b.

[0029] The protrusion 2122 is formed by integrally forming the protruding frame portion 2122a and the airtight material arrangement frame 2122b, has the same width in the vertical direction, and protrudes toward the outside X1 from the lower end of the outside X1 side end of the hollow frame 2121. The visible surface of the outside X1 side end of the protrusion 2122, which is also the visible surface 2122c of the outside X1 side end of the airtight material arrangement frame 2122b, is formed as a surface that has a width in the vertical direction and extends in the left-right direction when viewed from the front of the outside side X1, and is arranged so that it is exposed to the outside X1. The protrusion 2122 is arranged so that the visible surface 2122c, which is formed by the end face of the outside X1 side end of the frame portion of the airtight material arrangement frame 2122b of the protrusion 2122, is exposed to the outside X1.

[0030] The width H11 in the vertical direction (front direction) of the facing surface 2122c exposed to the outside X1 at the end of the protrusion 2122 on the outside side X1 is one-third or less of the width H12 in the vertical direction (front direction) at the end of the hollow frame 2121 on the outside side X1. In this embodiment, the width H11 in the front direction of the facing surface 2122c of the protrusion 2122 exposed to the outside side X1 is, for example, 1 to 3 mm.

[0031] In this embodiment, the surface of the door body 3, the surface of the visible surface 2122c of the end portion on the outside X1 side of the protrusion 2122, and the surface of the exterior building material 61 are arranged on approximately the same plane. In this embodiment, arranged on approximately the same plane not only includes a configuration in which the surface of the door body 3, the surface of the visible surface 2122c of the end portion on the outside X1 side of the protrusion 2122, and the surface of the exterior building material 61 are arranged on the same plane completely, but also a configuration in which the surface of the door body 3, the surface of the visible surface 2122c of the end portion on the outside X1 side of the protrusion 2122, and the surface of the exterior building material 61 are arranged on approximately a plane with a slight step that can be recognized as being on the same plane from the outside.

[0032] The L-shaped convex portion 2123 is formed continuously with the upper side of the end portion of the protrusion 2122 on the indoor side X2, and protrudes in an L shape above the outdoor side X1, spanning the upper part of the end portion of the protrusion 2122 on the indoor side X2 and the lower end portion of the vertically extending plate portion 2121b extending in the vertical direction at the end portion of the outdoor side X1 of the hollow frame 2121. The L-shaped convex portion 2123 has a horizontal plate portion 2123a (convex portion) extending a predetermined length toward the outdoor side X1 from the lower end portion of the vertically extending plate portion 2121b extending in the vertical direction at the end portion of the outdoor side X1 of the hollow frame 2121, and a vertical plate portion 2123b extending a predetermined length downward from the end portion of the horizontal plate portion 2123a on the outdoor side X1.

[0033] The vertical plate portion 2123b is arranged to cover the indoor side X2 portion of the gap between the protrusion portion 2122 of the upper frame 21 and the exterior wall material 61 in order to provide space for filling sealing material 631 between the protrusion portion 2122 of the upper frame 21 and the exterior wall material 61 when attaching the exterior wall material 61 to the outdoor side X1 of the building structure 100.

[0034] The horizontal plate portion 2123a is formed on the visible surface of the outdoor side X1 of the upper frame 21 closer to the outer periphery than the protrusion portion 2122, and protrudes toward the outdoor side X1. The horizontal plate portion 2123a is formed in a plate shape that protrudes toward the outdoor side X1 from the lower end of the vertically extending plate portion 2121b, from a position that is spaced upward (outer periphery) from the upper surface of the protrusion portion 2122 by the size of the gap between the protrusion portion 2122 and the exterior wall material 61.

[0035] The lower end of the exterior building material 61 is placed in contact with the horizontal plate portion 2123a. The horizontal plate portion 2123a regulates the position of the lower end (the end on the inner periphery) of the exterior building material 61 at a position spaced upward from the upper surface of the protrusion portion 2122 of the upper frame 21 by the size of the gap between the protrusion portion 2122 of the upper frame 21 and the exterior building material 61. The horizontal plate portion 2123a regulates the exterior building material 61 so that it does not move downward.

[0036] With the horizontal plate portion 2123a restricting the position of the lower end of the exterior wall material 61, the vertical plate portion 2123b is arranged to block the indoor side X2 portion of the gap between the protrusion portion 2122 of the upper frame 21 and the exterior wall material 61, so that a space that is open to the outdoor side X1 is formed between the outdoor side X1 surface of the vertical plate portion 2123b, the projected surface extending in the projected direction of the lower end of the exterior wall material 61, and the projected surface of the upper end of the protrusion portion 2122 of the upper frame 21.

Recesses 2320b, 2420b recessed toward the outdoor side X1 are formed on the indoor side X2 surface of the indoor hollow frames 2320, 2420.

[0048] The outdoor hollow frames 2321, 2421 are formed smaller than the indoor hollow frames 2320, 2420 in the left-right direction, and are arranged on the outdoor side X1 outside the indoor hollow frames 2320, 2420 in the left-right direction.

[0049] The outdoor hollow frames 2321, 2421 are formed smaller than the left-right size of the indoor hollow frames 2320, 2420 and are arranged on the outdoor side X1 outside the indoor hollow frames 2320, 2420 in the left-right direction, so that L-shaped recessed spaces 234, 244 are formed in the outdoor side X1 part on the inner periphery in the left-right direction. The L-shaped recessed spaces 234, 244 are formed in an L shape that opens toward the outdoor side X1 on the inner periphery in the left-right direction.

[0050] 3 , the L-shaped recessed space 234 (recess) formed on the hanging side of the door main body 3 is recessed from the outside X1 to the inside X2 at the inner circumferential end of the vertical frame 23 in the left-right direction by the end face 301 on the hanging side of the door main body 3 in the left-right direction, the door main body 3-side surface of the vertical frame 23 on the hanging side of the door main body 3, and the door main body 3-side surface of the protrusion 2322, and extends over the entire vertical direction of the door main body 3. The L-shaped recessed space 244 (recess) formed on the hanging side of the sub-door 4 is recessed from the outside X1 to the inside X2 at the inner circumferential end of the vertical frame 24 in the left-right direction by the end face 401 on the hanging side of the sub-door 4 in the left-right direction, the sub-door 4-side surface of the vertical frame 24 on the hanging side, and the sub-door 4-side surface of the protrusion 2422, and extends over the entire vertical direction of the sub-door 4.

[0051] The rotation axis portions of the hinges 31, 41 are disposed in the L-shaped recessed spaces 234, 244. The L-shaped recessed spaces 234, 244 are formed on the inner periphery of the protrusions 2322, 2422 on the inner periphery of the vertical frames 23, 24, and are recessed so that when the door main body 3 or the sub-door 4 rotates around the hinges 31, 41 as a rotation axis, the inner periphery of the vertical frames 23, 24 is open and the outside side X1 is open so as to avoid the left and right ends of the door main body 3 or the sub-door 4 rotatably supported on the hinges 31, 41.

[0052] The indoor X2 surfaces of the exterior wall materials 63, 63 are arranged on the outdoor X1 surfaces of the left-right extending plate portions 2321b, 2421b that extend in the left-right direction at the outdoor X1 side ends of the outdoor hollow frames 2321, 2421. The left-right extending plate portions 2321b, 2421b form backup portions that are arranged along the back surfaces of the indoor X2 sides of the exterior wall materials 63, 64.

[0053] The exterior wall materials 63, 64 are composed of panels in which tiles 63b, 64b are attached to the exterior side X1 of ceramic siding base materials 63a, 64a. The ceramic siding base materials 63a, 64a and the tiles 63b, 64b are fixed with adhesive 63c, 64c. The exterior wall materials 63, 64 are attached to the exterior side X1 of the furring strips 120 around the door frame 2. The exterior wall materials 63, 64 are formed in a plate shape extending outward in the left-right direction from the end of the outermost side of the door frame 2 on the outer periphery of the door frame 2, which is closest to the exterior side X1, with a gap left-right outward from the door frame 2. The exterior wall materials 63, 64 are arranged to the lateral sides of the outer periphery of the protrusions 2322, 2422 in the left-right direction (visual direction). The surface colors of the exterior side X1 of the door main body 3 and the sub-door 4 and the surface colors of the exterior wall materials 63, 64 are the same color or a color scheme of the same color.

[0054] The protrusions 2322, 2422 are formed on the facing surfaces of the outside X1 sides of the vertical frames 23, 24 and protrude toward the outside X1 side. The protrusions 2322, 2422 are arranged laterally on the inner periphery in the left-right direction (facing direction) of the exterior wall materials 63, 64. The protrusions 2322, 2422 are formed to protrude toward the outside X1 from the inner periphery end of the facing surface of the end of the outside X1 side in the left-right direction of the outdoor hollow frames 2321, 2421 (hollow frames), and protrude in the facing direction to the position of the surface of the outside X1 side of the exterior wall materials 63, 64. The protrusions 2322, 2422 protrude toward the outside X1 from the facing surfaces of the outside X1 sides of the vertical frames 23, 24 to a length in the facing direction that is the same as the thickness of the exterior wall materials 63, 64.

[0055] The protrusions 2322, 2422 are formed in the shape of a plate having a thickness in the left-right direction. Specifically, the protrusions 2322, 2422 are formed from a single planar flat plate having only the plate thickness in the left-right direction (view direction) without a hollow portion, and extend in the view direction and the up-down direction.

[0056] The visible surfaces 2322a, 2422a of the ends of the protrusions 2322, 2422 on the outside side X1 are formed as a surface that has a width equal to the thickness of the plate thickness of the plate portion in the left-right direction and extends in the up-down direction when viewed from the front of the outside side X1, and are arranged so as to be exposed on the outside side X1. The protrusions 2322, 2422 are arranged so that the visible surfaces 2322a, 2422a formed by the end faces of the ends of the plate portions on the outside side X1 are exposed on the outside side X1. Only the end faces of the outside side X1 of the plate thickness of the plate portions of the protrusions 2322, 2422 are exposed on the outside side X1.

[0057] The widths H31, H41 in the left-right direction (front view direction) of the facing surfaces 2322a, 2422a exposed to the outside X1 at the ends of the protrusions 2322, 2422 on the outside X1 side are one-third or less of the widths H32, H42 in the left-right direction (front view direction) at the ends of the outside X1 side of the outdoor hollow frames 2321, 2421. In this embodiment, the widths H31, H41 in the front view direction of the facing surfaces 2322a, 2422a exposed to the outside X1 of the protrusions 2322, 2422 are, for example, 1 to 3 mm.

[0058] In this embodiment, the surface of the door main body 3, the surface of the visible surface 2322a of the end of the protrusion 2322 on the outside X1 side, and the surface of the exterior wall material 63 are arranged on approximately the same plane. Also, the surface of the secondary door 4, the surface of the visible surface 2422a of the end of the protrusion 2422 on the outside X1 side, and the surface of the exterior wall material 64 are arranged on approximately the same plane. In this embodiment, arranged on approximately the same plane not only includes a configuration in which the surface of the door main body 3, the surface of the secondary door 4, the surfaces of the visible surfaces 2322a, 2422a of the end of the protrusions 2322, 2422 on the outside X1 side, and the surfaces of the exterior wall materials 63, 64 are arranged on the same plane completely, but also includes a configuration in which the surface of the door main body 3, the surface of the secondary door 4, the surfaces of the visible surfaces 2322a, 2422a of the end of the protrusions 2322, 2422 on the outside X1 side, and the surfaces of the exterior wall materials 63, 64 are arranged on approximately the same plane with a slight step that allows them to be recognized as being on the same plane from the outside.

[0059] The inner left-right ends of the left-right extending plate portions 2321b, 2421b extending in the left-right direction at the ends of the outside wall materials 63, 64 on the outside X1 side of the outdoor hollow frames 2321, 2421 are arranged to block the inside X2 part of the gap between the vertical frames 23, 24 and the exterior wall materials 63, 64 in order to provide space for filling sealing material 633, 634 between the vertical frames 23, 24 and the exterior wall materials 63, 64 when attaching the exterior wall materials 63, 64 to the outside X1 side of the building body 100.

[0060] The convex portions 2323, 2423 are formed on the visible surface of the outdoor side X1 of the vertical frames 23, 24 more outer circumferential than the protrusions 2322, 2422, and are formed in a plate shape protruding toward the outdoor side X1. The convex portions 2323, 2423 are formed in a plate shape protruding toward the outdoor side X1 from the inner circumferential end of the left-right extending plate portions 2321b, 2421b, at a position spaced apart from the outer circumferential surface of the protrusions 2322, 2422 in the left-right direction by the size of the gap between the protrusions 2322, 2422 and the exterior wall materials 63, 64.

[0061] The inner circumferential ends of the exterior wall materials 63, 64 in the left-right direction are positioned to abut against the protrusions 2323, 2423. The protrusions 2323, 2423 restrict the position of the inner circumferential ends of the exterior wall materials 63, 64 at positions spaced outward in the left-right direction from the outer circumferential faces of the protrusions 2322, 2422 of the vertical frames 23, 24 by the size of the gap between the protrusions 2322, 2422 of the vertical frames 23, 24 and the exterior wall materials 63, 64. The protrusions 2323, 2423 restrict the exterior wall materials 63, 64 from moving inward in the left-right direction.

[0062] With the convex portions 2323, 2423 restricting the positions of the inner peripheral ends in the left-right direction of the exterior wall materials 63, 64, the inner peripheral ends in the left-right direction of the left-right extending plate portions 2321b, 2421b extending in the left-right direction on the outside X1 of the outdoor hollow frames 2321, 2421 are arranged to block the indoor side X2 portion of the gap between the protrusions 2322, 2422 of the vertical frames 23, 24 and the outdoor wall materials 63, 64. As a result, a space that is open to the outside surface X1 is formed between the outside surface X1 surface of the inner circumferential end portion in the left-right direction of the left-right extending plate portion 2321b, 2421b that extends in the left-right direction on the outside surface X1 of the outdoor hollow frame 2321, 2421, the projected surface extending in the projected direction of the inner circumferential end portion in the left-right direction of the exterior wall material 63, 64, and the projected surface of the outer circumferential end portion in the left-right direction of the protrusion portion 2322, 2422 of the vertical frame 23, 24.

[0063] 3 and 4, backup materials 643, 644 are arranged on the indoor side X2 in the space formed between the outdoor side X1 surfaces of the inner circumferential ends in the horizontal direction of the horizontally extending plate portions 2321b, 2421b that extend in the horizontal direction and are formed at the outdoor side X1 ends of the outdoor hollow frames 2321, 2421, the visible surfaces extending in the visible direction of the inner circumferential ends in the horizontal direction of the exterior wall materials 63, 64, and the outer circumferential visible surfaces in the horizontal direction of the protrusions 2322, 2422 of the vertical frames 23, 24. The backup materials 643, 644 are separate members from the vertical frames 23, 24.

[0064] The backup materials 643, 644 are formed in the shape of plates that have a thickness in the left-right direction, a predetermined width in the projection direction, and extend in the up-down direction. In this embodiment, the backup materials 643, 644 are configured by setting blocks, and the vertical frames 23, 24 and the backup materials 643, 644 are fixed with double-sided tape or adhesive, or the exterior wall materials 63, 64 and the backup materials 643, 644 are fixed with double-sided tape or adhesive.

[0065] The backup materials 643, 644, together with the protrusions 2323, 2423, regulate the positions of the inner side ends (ends on the inner periphery) in the left-right direction of the exterior wall materials 63, 64. The backup materials 643, 644 regulate the exterior wall materials 63, 64 so that they do not move inward in the left-right direction.

[0066] The space formed between the outside X1 surface of the inner circumferential end of the left-right extending plate portion 2321b, 2421b extending in the left-right direction at the outside X1 end of the outdoor hollow frame 2321, 2421, the projected surface extending in the projected direction of the inner circumferential end of the exterior wall material 63, 64, and the projected surface of the outer circumferential end of the protrusion portion 2322, 2422 of the vertical frame 23, 24 is filled with sealing material 633, 634 that is arranged between the protrusion portion 2322, 2422 of the vertical frame 23, 24 and the exterior wall material 63, 64 on the outside X1 and fills the gap between the protrusion portion 2322, 2422 of the vertical frame 23, 24 and the exterior wall material 63, 64. As a result, the sealing materials 633, 634 are arranged between the protrusions 2322, 2422 of the vertical frames 23, 24 and the exterior wall materials 63, 63. In this embodiment, the color of the sealing materials 633, 634 is the same color as the color of the exterior wall materials 63, 64 or a color of the same color family.

[0067] The fitting 1 of the first embodiment described above provides the following advantages. The fitting 1 of this embodiment includes a door frame 2, a door body 3 and a sub-door 4 disposed within the door frame 2, and exterior wall materials 61, 63, and 64. The door frame 2 has protrusions 2122, 2322, and 2422 formed on the facing surface of the exterior side X1 of the door frame 2 and protruding toward the exterior side X1. The exterior wall materials 61, 63, and 64 are disposed to the sides of the protrusions 2122, 2322, and 2422 in the facing direction. By narrowing the width of the protrusions 2122, 2322, and 2422 in the facing direction, the fitting 1 has a streamlined appearance and can improve design. Furthermore, the simple configuration in which the exterior wall materials 61, 63, and 64 are disposed to the sides of the protrusions 2122, 2322, and 2422 in the facing direction improves installation workability. Therefore, the design can be improved while the construction can be improved with a simple configuration.

[0068] Furthermore, in this embodiment, the protrusions 2122, 2322, 2422 protrude from the exterior surface X1 of the door frame 2 (top frame 21, vertical frames 23, 24) toward the exterior side X1 by a length in the projection direction that is the same as the thickness of the exterior wall materials 61, 63, 64. As a result, the length in the projection direction of the protrusions 2122, 2322, 2422 is the same as the length in the projection direction that is the same as the thickness of the exterior wall materials 61, 63, 64, and therefore the exterior wall materials 61, 63, 64 can be easily arranged along the protrusions 2122, 2322, 2422 with the exterior wall materials 61, 63, 64 arranged to the side of the protrusions 2122, 2322, 2422 in the projection direction.

[0069] In this embodiment, the facing surfaces 2122c, 2322a, and 2422a of the ends of the protrusions 2122, 2322, and 2422 on the outside side X1 are exposed to the outside side X1. The facing widths H11, H31, and H41 of the facing surfaces of the protrusions 2122, 2322, and 2422 exposed to the outside side X1 are 1 to 3 mm. As a result, the facing surfaces 2122c, 2322a, and 2422a of the ends of the protrusions 2122, 2322, and 2422 on the outside side X1 are exposed to the outside side X1 with a narrow facing direction width. Therefore, compared to when the facing surface on the outside side X1 of the door frame 2 is exposed to the outside side X1 with a wide width, only the minimum necessary portion is exposed to the outside side X1, resulting in a sleeker appearance and improved design.

[0070] In the present embodiment, the protrusions 2322, 2422 are formed in a plate shape. As a result, only the visible surface of the plate thickness portion with a narrow width in the visible direction at the end of the protrusions 2322, 2422 on the outdoor side X1 is exposed to the outdoor side X1, thereby improving the design.

[0071] Furthermore, in this embodiment, the protrusions 2122, 2322, 2422 protrude toward the outside X1 from the facing surfaces of the outside X1 of the hollow frame 2121 and the outdoor hollow frames 2321, 2421. This allows the protrusions 2122, 2322, 2422 to protrude toward the outside X1 from the facing surfaces of the outside X1 of the hollow frame 2121 and the outdoor hollow frames 2321, 2421, which have hollow portions and have improved strength, and therefore the strength of the protrusions 2122, 2322, 2422 can be improved.

[0072] Furthermore, in the present embodiment, the widths H11, H31, H41 in the front direction of the facing surfaces of the protrusions 2122, 2322, 2422 exposed to the outside side X1 are one-third or less of the widths H12, H32, H42 in the front direction at the ends of the hollow frame 2121 and the outdoor hollow frame 2321, 2421 on the outside side X1. Thus, by making the widths H11, H31, H41 in the front direction of the facing surfaces of the protrusions 2122, 2322, 2422 smaller than the widths H12, H32, H42 in the front direction at the ends on the outside side X1, and thereby narrowing the widths in the front direction of the protrusions 2122, 2322, 2422, it is possible to achieve a sleek appearance from an external perspective and improve the design.

[0073] Furthermore, in this embodiment, hinges 31, 41 are provided that are disposed closer to the indoor side X2 than the outdoor side X1 surface of the exterior wall materials 61, 63, 64 and rotatably support the door main body 3 and the sub-door 4, and the vertical frames 23, 24 of the door frame 2 have recessed spaces 234, 244 that are formed on the inner peripheral side of the vertical frames 23, 24 on the inner peripheral side of the protrusions 2122, 2322, 2422 and are recessed so that the inner peripheral side of the vertical frames 23, 24 is open and the outdoor side X1 is open so as to avoid the left and right ends of the door main body 3 and the sub-door 4 that are rotated by the hinges 31, 41. Thus, by configuring the left and right ends of the door main body 3 and the sub-door 4 that are rotated by the hinges 31, 41 to avoid being exposed to the recessed spaces 234, 244, a structure in which the hinges 31, 41 are hidden by the door main body 3 and the sub-door 4 can be easily realized.

[0074] Furthermore, in this embodiment, the door frame 2 has horizontal plate portions 2123a and convex portions 2323, 2423 that are formed on the visible surface of the outdoor side X1 of the door frame 2 (top frame 21, vertical frames 23, 24) more outer than the protrusions 2122, 2322, 2422, protrude toward the outdoor side X1, and regulate the positions of the inner peripheral ends of the exterior wall materials 61, 63, 64. As a result, the horizontal plate portions 2123a and the convex portions 2323, 2423 can regulate the positions of the inner peripheral ends of the exterior wall materials 61, 63, 64, making it easier to attach the exterior wall materials 61, 63, 64 and improving workability.

[0075] Furthermore, in this embodiment, the surfaces of the door main body 3 and the sub-door 4, the visible surfaces of the ends of the protrusions 2122 on the outside X1 side, and the surface of the exterior wall material 61 are arranged on approximately the same plane. The surfaces of the door main body 3 and the sub-door 4, the visible surfaces of the ends of the protrusions 2322, 2422 on the outside X1 side, and the surfaces of the exterior wall materials 63, 63 are arranged on approximately the same plane. As a result, the surfaces of the door main body 3 and the sub-door 4, the visible surfaces of the ends of the protrusions 2122, 2322, 2422 on the outside X1 side, and the surfaces of the exterior wall materials 61, 63, 64 are arranged on approximately the same plane, thereby improving the design.

[0076] Furthermore, this embodiment includes sealing materials 631, 633, 634 that are arranged between the exterior wall materials 61, 63, 64 and the protrusions 2122, 2322, 2422. This makes it possible to improve the waterproofing performance between the exterior wall materials 61, 63, 64 and the protrusions 2122, 2322, 2422.

[0077] In this embodiment, the colors of the sealing materials 631, 633, and 634 are the same color or a color of the same family as the colors of the exterior wall materials 61, 63, and 64. This allows for improved design, as the colors of the sealing materials 631, 633, and 634 are the same color or a color of the same family as the colors of the exterior wall materials 61, 63, and 64.

[0078] In this embodiment, the surface color of the exterior side X1 of the door body 3 and the sub-door 4 is the same color or a color of the same family as the surface color of the exterior wall materials 61, 63, 64. This improves the design.

[0079] Next, a second embodiment will be described with reference to Fig. 5. The outer frame 242X of the vertical frame 24X of the second embodiment differs from the outer frame 242 of the vertical frame 24 of the first embodiment mainly in that it has an L-shaped adjustment frame portion 25 (position adjustment mechanism) that can adjust the position of the exterior wall material 64X in the projection direction. In the second embodiment, only the configuration of the outer frame 242X of the vertical frame 24X differs from the configuration of the outer frame 242 of the vertical frame 24 of the first embodiment shown in Fig. 4, and the other configurations are similar to those of the first embodiment. For the outer frame 242X of the vertical frame 24X of the second embodiment, the same components as those of the first embodiment are assigned the same reference numerals, and their description will be omitted.

[0080] 5, the vertical frame 24X of the second embodiment has an outdoor frame 242X. The outdoor frame 242X includes an indoor-side hollow frame 2420 having an indoor-side hollow portion 2420a, protrusions 2422X protruding toward the outdoor side X1 from a left-right midway portion of the surface of the indoor-side hollow frame 2420 on the outdoor side X1, and an L-shaped adjustment frame portion 25 (position adjustment mechanism). The indoor-side hollow frame 2420 and the protrusions 2422X are formed integrally, and the L-shaped adjustment frame portion 25 is formed separately from the indoor-side hollow frame 2420 and the protrusions 2422X.

[0081] The L-shaped adjustment frame portion 25 is configured to be able to adjust the position of the exterior wall material 64X in the projection direction, and therefore the position at which it supports the exterior wall material 64X can be adjusted to match the thickness of the exterior wall material 64X. The L-shaped adjustment frame portion 25 is formed in an L shape and has a mounting plate 251, a backup plate portion 252, and a restricting plate portion 253.

[0082] The mounting plate 251 is formed in a plate shape extending in the projection direction, and is fixed with screws 25a on the indoor side X2 to the projection surface of the outer peripheral end portion in the left-right direction of the indoor side hollow frame 2420, and is formed in a plate shape extending from the projection surface of the outer peripheral end portion in the left-right direction of the indoor side hollow frame 2420 to the outdoor side X1. The mounting plate 251 can be fixed with screws 25a to the projection surface of the outer peripheral end portion in the left-right direction of the indoor side hollow frame 2420 with its position in the projection direction adjusted.

[0083] The backup plate 252 is formed in a plate shape such that its inner left-right end extends inward in the left-right direction from the end on the outside side X1 of the mounting plate 251 to the position of the outer left-right surface of the protrusion 2422X. The exterior wall material 64X is placed on the outside side X1 surface of the backup plate 252. The backup plate 252 constitutes a backup part that is placed along the back surface of the inside side X2 of the exterior wall material 64X.

[0084] The restricting plate 253 is formed in a plate shape that protrudes toward the outside surface X1 from a portion of the backup plate 252 closer to the inner periphery in the left-right direction. The restricting plate 253 protrudes toward the outside surface X1 at a position away from the outer periphery in the left-right direction by a distance sufficient to form a gap between the exterior wall material 64X and the protruding portion 2422X, in order to place the sealing material 634 (see FIG. 5) in the gap on the outside surface X1 between the exterior wall material 64X and the protruding portion 2422X. The restricting plate 253 restricts the position of the end portion on the inner periphery in the left-right direction of the exterior wall material 64X.

[0085] When adjusting the position of the exterior wall material 64X in the prospective direction using the L-shaped adjustment frame part 25 configured as described above, the L-shaped adjustment frame part 25 is moved in the prospective direction to adjust the position in the prospective direction in accordance with the thickness of the exterior wall material 64X, and then the mounting plate 251 of the L-shaped adjustment frame part 25 is fixed with the screws 25a to the prospective surface of the end part on the outer periphery in the left-right direction of the indoor-side hollow frame 2420. For fixing with the screws 25a, for example, the screws 25a are configured as drill screws, and the screws 25a are inserted at the construction site to pass through the mounting plate 251 of the L-shaped adjustment frame part 25 and the prospective surface of the end part on the outer periphery in the left-right direction of the indoor-side hollow frame 2420 for fixing.

[0086] As described above, the second embodiment is provided with the L-shaped adjustment frame portion 25, and can accommodate the thickness of the exterior building material 64X by adjusting the position of the L-shaped adjustment frame portion 25 in the projection direction according to the thickness of the exterior building material 64X. This allows the exterior building material 64X to be easily attached with a simple configuration.

[0087] Next, a third embodiment will be described with reference to Figures 6 to 8. In the first embodiment, the upper frame 21 is provided with an L-shaped protrusion 2123, and the vertical frames 23, 24 are provided with protrusions 2323, 2423. In contrast, in the third embodiment, the upper frame 21A is not provided with an L-shaped protrusion 2123, and a backup material 641 is disposed between the upper frame 21A and the exterior wall material 61, and the vertical frames 23A, 24A are not provided with protrusions 2323, 2423, and backup materials 643, 644 are disposed between the vertical frames 23A, 24A and the exterior wall materials 63, 64. In the third embodiment, components similar to those in the first embodiment are denoted by the same reference numerals, and their description will be omitted.

[0088] As shown in Fig. 6, in the third embodiment, the upper frame 21A does not have the L-shaped protrusion 2123 of the upper frame 21 in Fig. 2 of the first embodiment. A backup material 641 is arranged in the indoor side X2 portion of the gap between the upper surface of the protrusion 2122 of the upper frame 21A and the lower end of the exterior wall material 61. The backup material 641 is a separate member from the upper frame 21A.

[0089] As shown in Figure 6, the backup material 641 is arranged on the indoor side X2 of the gap between the upper surface of the protrusion 2122 of the upper frame 21A and the lower end of the exterior building material 61, so as to form a gap between the protrusion 2122 of the upper frame 21A and the exterior building material 61. The backup material 641 is formed in a plate shape with a thickness in the vertical direction, a predetermined width in the projection direction, and extends in the horizontal direction. In this embodiment, the backup material 641 is made of a setting block, and the upper frame 21A and the backup material 641 are fixed together with double-sided tape or adhesive, or the exterior building material 61 and the backup material 641 are fixed together with double-sided tape or adhesive.

[0090] The backup material 641 regulates the position of the lower end (end on the inner periphery side) of the exterior wall material 61. The backup material 641 regulates the exterior wall material 61 so that it does not move downward.

[0091] With the position of the lower end of the exterior wall material 61 restricted by the backup material 641, the backup material 641 is arranged to block the indoor side X2 portion of the gap between the protrusion 2122 of the upper frame 21A and the exterior wall material 61, so that a space that is open to the outdoor side X1 is formed between the outdoor side X1 surface of the backup material 641, the projected surface extending in the projected direction of the lower end of the exterior wall material 61, and the upper surface of the protrusion 2122 of the upper frame 21A.

[0092] The space formed among the outside-surface X1 of the backup material 641, the projected surface extending in the projected direction of the lower end of the exterior wall material 61, and the upper surface of the protrusion 2122 of the upper frame 21A is filled with a sealant 631 that is disposed between the protrusion 2122 of the upper frame 21A and the exterior wall material 61 on the outside X1 and fills the gap between the protrusion 2122 of the upper frame 21A and the exterior wall material 61. In this embodiment, the color of the sealant 631 is the same color as the color of the exterior wall material 61 or a color of the same color family.

[0093] As shown in Figures 7 and 8, the vertical frames 23A, 24A of the third embodiment are not provided with the protruding portions 2323, 2423 of the vertical frames 23, 24 of the first embodiment shown in Figures 3 and 4. Backup materials 643, 644 are arranged in the indoor side X2 portion of the gap between the outer visible surfaces in the left-right direction of the protruding portions 2322, 2422 of the vertical frames 23A, 24A and the inner visible surfaces in the left-right direction of the exterior wall material 63. The backup materials 643, 644 are separate members from the vertical frames 23A, 24A.

[0094] As shown in Figures 7 and 8, the backup materials 643, 644 are arranged on the indoor side X2 of the gap between the outer left-right surfaces of the protrusions 2322, 2422 of the vertical frames 23A, 24A and the outer left-right surfaces of the exterior wall materials 63, 64, so as to form a gap between the protrusions 2322, 2422 of the vertical frames 23A, 24A and the exterior wall materials 63, 64. The backup materials 643, 644 are formed in the shape of plates with a thickness in the left-right direction, a predetermined width in the projection direction, and extend in the left-right direction. In this embodiment, the backup materials 643, 644 are formed from setting blocks, and the vertical frames 23A, 24A and the backup materials 643, 644 are fixed together with double-sided tape or adhesive, or the exterior wall materials 63, 64 and the backup materials 643, 644 are fixed together with double-sided tape or adhesive.

[0095] The backup materials 643, 644 regulate the positions of the inner side ends (ends on the inner periphery side) in the left-right direction of the exterior wall materials 63, 64. The backup materials 643, 644 regulate the exterior wall materials 63, 64 so that they do not move inward in the left-right direction.

[0096] The backup materials 643, 644 restrict the position of the inner left-right ends of the exterior wall materials 63, 64, and are arranged to block the indoor side X2 portion of the gap between the protrusions 2322, 2422 of the vertical frames 23A, 24A and the exterior wall materials 63, 64.As a result, a space that is open to the outdoor side X1 is formed between the outdoor side X1 surfaces of the backup materials 643, 644, the visible surfaces extending in the visible direction of the inner left-right ends of the exterior wall materials 63, 64, and the outer left-right visible surfaces of the protrusions 2322, 2422 of the vertical frames 23A, 24A.

[0097] The space formed between the outside-surface X1 surfaces of the backup materials 643, 644, the prospective surfaces extending in the prospective direction of the inner left-right ends of the exterior wall materials 63, 64, and the outer left-right prospective surfaces of the protrusions 2322, 2422 of the vertical frames 23A, 24A is filled with sealing materials 633, 634 that are arranged between the protrusions 2322, 2422 of the vertical frames 23A, 24A and the exterior wall materials 63, 64 on the outside X1 and fill the gaps between the protrusions 2322, 2422 of the vertical frames 23A, 24A and the exterior wall materials 63, 64. As a result, the sealing materials 633, 634 are arranged between the protrusions 2322, 2422 of the vertical frames 23A, 24A and the exterior wall materials 63, 64. In this embodiment, the color of the sealing materials 633, 634 is the same color as the color of the exterior wall materials 63, 64 or a color of the same color family.

[0098] The third embodiment configured as above can achieve the same effects as the first embodiment.

[0099] Next, a fourth embodiment will be described with reference to FIG. 9. The outdoor frame 242Y of the vertical frame 24Y of the fourth embodiment differs from the outdoor frame 242A of the vertical frame 24A shown in FIG. 8 of the third embodiment mainly in that it has an L-shaped adjustment frame portion 25Y (position adjustment mechanism) that can adjust the position of the exterior wall material 64Y in the projection direction. In the fourth embodiment, only the configuration of the outdoor frame 242Y of the vertical frame 24Y differs from the configuration of the outdoor frame 242A of the vertical frame 24A shown in FIG. 8 of the third embodiment, while the other configurations are similar to those of the third embodiment. Also, the L-shaped adjustment frame portion 25Y (position adjustment mechanism) of the fourth embodiment differs from the L-shaped adjustment frame portion 25 (position adjustment mechanism) of the second embodiment shown in FIG. 5 in that it does not have a restricting plate portion 253, whereas the L-shaped adjustment frame portion 25 shown in FIG. 5 of the second embodiment has a restricting plate portion 253. Regarding the outdoor frame 242Y of the vertical frame 24Y of the fourth embodiment, the same components as those in the second and third embodiments are denoted by the same reference numerals, and the description thereof will be omitted.

[0100] 9, the vertical frame 24Y of the fourth embodiment has an outdoor frame 242Y. The outdoor frame 242Y includes an indoor-side hollow frame 2420 having an indoor-side hollow portion 2420a, protrusions 2422Y protruding toward the outdoor side X1 from a left-right midpoint of the surface of the indoor-side hollow frame 2420 on the outdoor side X1, and an L-shaped adjustment frame portion 25Y (position adjustment mechanism). The indoor-side hollow frame 2420 and the protrusions 2422Y are formed integrally, and the L-shaped adjustment frame portion 25Y is formed separately from the indoor-side hollow frame 2420 and the protrusions 2422Y.

[0101] The L-shaped adjustment frame portion 25Y is configured to be adjustable in its position in the projection direction of the exterior wall material 64Y, making it possible to adjust the position at which it supports the exterior wall material 64Y to match the thickness of the exterior wall material 64Y. The L-shaped adjustment frame portion 25Y is formed in an L-shape and has an attachment plate 251 and a backup plate portion 252. The configurations of the attachment plate 251 and the backup plate portion 252 are the same as those of the third embodiment shown in Fig. 5, and therefore description thereof will be omitted.

[0102] As described above, the fourth embodiment is provided with the L-shaped adjustment frame portion 25Y, and similarly to the second embodiment, the position of the L-shaped adjustment frame portion 25Y in the projection direction can be adjusted according to the thickness of the exterior building material 64Y, thereby making it possible to easily attach the exterior building material 64Y with a simple configuration.

[0103] Next, a fifth embodiment will be described with reference to Figures 10 to 12. The fifth embodiment is an embodiment in which, in the configuration of the third embodiment, backup materials 641, 643, 644 are not provided, and backup fittings 651, 652, 653 (backup portions) are provided along the back surfaces of exterior wall materials 61, 63, 64. In the fifth embodiment, components similar to those in the third embodiment are denoted by the same reference numerals, and their description will be omitted.

[0104] As shown in FIG. 10, a backup metal fitting 651 (backup part) is provided on the rear surface of the exterior building material 61 on the indoor side X2.

[0105] The backup fitting 651 is disposed on the rear surface of the exterior building material 61, at the lower end of the exterior building material 61. The backup fitting 651 is made of metal, and is fixed to the outdoor side X1 surface of the vertically extending plate portion 2121b of the hollow frame 2121 of the outdoor frame 212A of the upper frame 21A.

[0106] The backup fittings 651 are arranged to block the indoor side X2 portion of the gap between the upper frame 21A and the exterior wall material 61 in order to provide space for filling the sealing material 631 between the upper frame 21A and the exterior wall material 61 when attaching the exterior wall material 61 to the outdoor side X1 of the building structure 100.

[0107] The backup metal fitting 651 has a mounting plate 651a (first portion) that is attached to the indoor side X2 surface of the exterior wall material 61, and a rising protrusion 651b (second portion) that is L-shaped in cross section and protrudes toward the outdoor side X1. The mounting plate 651a and the rising protrusion 651b are formed by folding back a single steel plate.

[0108] The mounting plate 651a is arranged on the back surface (the indoor side X2 surface) of the exterior wall material 61, and is formed like a plate that extends in the vertical direction and in the longitudinal direction of the upper frame 21A. The mounting plate 651a is arranged at the lower end of the exterior wall material 61 along the indoor side X2 surface of the exterior wall material 61, and is attached to the indoor side X2 surface of the exterior wall material 61. The mounting plate 651a is arranged between the exterior wall material 61 and the outdoor side X1 surface of the vertically extending plate portion 2121b of the hollow frame 2121 of the outdoor side frame 212 of the upper frame 21A.

[0109] The rising protrusion 651b is formed in an L-shaped frame shape that opens upward, and protrudes from the end of the mounting plate 651a on the upper frame 21A side in the vertical direction toward the outside room X1. The rising protrusion 651b is disposed at the end of the exterior wall material 61 on the upper frame 21A side, between the end of the exterior wall material 61 on the upper frame 21A side and the upper frame 21A. As a result, the rising protrusion 651b is provided so as to close the portion of the gap between the upper frame 21A and the exterior wall material 61 on the inside room X2.

[0110] By positioning the rising protrusion 651b between the exterior wall material 61 and the upper frame 21A at the end of the exterior wall material 61 on the upper frame 21A side, a space that is open to the outside surface X1 is formed between the outside surface X1 of the rising protrusion 651b, the visible surface extending in the visible direction of the lower end of the exterior wall material 61, and the visible surface of the upper end of the protrusion 2122 of the upper frame 21A.

[0111] The space formed between the outside X1 surface of the rising convex portion 651b, the projected surface extending in the projected direction of the lower end of the exterior wall material 61, and the projected surface of the upper end of the protrusion portion 2122 of the upper frame 21A is filled with sealing material 631 that is disposed between the upper frame 21A and the exterior wall material 61 and fills the gap between the upper frame 21A and the exterior wall material 61.

[0112] As shown in FIGS. 11 and 12, backup metal fittings 653, 654 (backup portions) are provided on the rear surfaces of the exterior wall materials 63, 64 on the indoor side X2.

[0113] The backup metal fittings 653, 654 are arranged on the rear surfaces of the exterior wall materials 63, 64 at the inner peripheral ends of the exterior wall materials 63, 64. The backup metal fittings 653, 654 are made of metal, and are fixed to the outdoor side X1 surfaces of the left-right extending plate portions 2321b, 2421b of the outdoor hollow frames 2321, 2421 (hollow frames) of the outdoor frames 232A, 242A of the vertical frames 23A, 24A.

[0114] The backup fittings 653, 654 are arranged to block the indoor side X2 portion of the gap between the vertical frames 23A, 24A and the exterior wall materials 63, 64 in order to provide space for filling sealing materials 633, 634 between the vertical frames 23A, 24A and the exterior wall materials 63, 64 when attaching the exterior wall materials 63, 64 to the outdoor side X1 of the building structure 100.

[0115] The backup fittings 653, 654 have mounting plates 653a, 654a (first portions) attached to the indoor side X2 surface of the exterior wall materials 63, 64, and rising protrusions 653b, 654b (second portions) that are L-shaped in cross section and protrude toward the outdoor side X1. The mounting plates 653a, 654a and the rising protrusions 653b, 654b are formed by folding back a single steel plate.

[0116] The mounting plates 653a, 654a are arranged on the back surfaces (the indoor-side X2 surfaces) of the exterior wall materials 63, 64, and are formed like plates extending in the left-right direction and in the longitudinal direction of the vertical frames 23A, 24A. The mounting plates 653a, 654a are arranged along the indoor-side X2 surfaces of the exterior wall materials 63, 64 at the inner left-right ends of the exterior wall materials 63, 64, and are attached to the indoor-side X2 surfaces of the exterior wall materials 63, 64. The mounting plates 653a, 654a are arranged between the exterior wall materials 63, 64 and the outdoor-side X1 surfaces of the left-right extending plate portions 2321b, 2421b of the outdoor hollow frames 2321, 2421 (hollow frames) of the outdoor frames 232A, 242A of the vertical frames 23A, 24A.

[0117] The rising protrusions 653b, 654b are formed in an L-shaped frame shape that opens outward in the left-right direction, and protrude from the left-right ends of the mounting plates 653a, 654a on the vertical frames 23A, 24A side toward the outside wall surface X1. The rising protrusions 653b, 654b are disposed at the ends of the exterior wall materials 63, 64 on the vertical frames 23A, 24A side, between the ends of the exterior wall materials 63, 64 on the vertical frames 23A, 24A side and the vertical frames 23A, 24A. As a result, the rising protrusions 653b, 654b are provided so as to close the portion of the gap between the vertical frames 23A, 24A and the exterior wall materials 63, 64 on the inside wall surface X2.

[0118] By arranging the rising protrusions 653b, 654b between the exterior wall materials 63, 64 and the vertical frames 23A, 24A at the ends of the exterior wall materials 63, 64 on the vertical frame 23A, 24A side, a space that is open to the outside surface X1 is formed between the outside surface X1 of the rising protrusions 653b, 654b, the visible surface extending in the visible direction of the inner circumferential end of the exterior wall materials 63, 64 in the left-right direction, and the visible surface on the outer circumferential side in the left-right direction of the protrusions 2322, 2422 of the vertical frames 23A, 24A.

[0119] The space formed between the outdoor X1 surface of the rising protrusions 653b, 654b, the projected surface extending in the projected direction of the inner circumferential end of the exterior wall materials 63, 64 in the left-right direction, and the projected surface on the outer circumferential side of the protrusions 2322, 2422 of the vertical frames 23A, 24A in the left-right direction is filled with sealing materials 633, 634 that are arranged between the vertical frames 23A, 24A and the exterior wall materials 63, 64 and fill the gap between the vertical frames 23A, 24A and the exterior wall materials 63, 64.

[0120] In this embodiment, backup metal fittings 651, 653, 654 are provided to be placed on the back surfaces of the exterior wall materials 61, 63, 64. As a result, by supporting the back surfaces of the exterior wall materials 61, 63, 64 with the backup metal fittings 651, 653, 654, the exterior wall materials 61, 63, 64 can be easily installed around the door frame 2 (upper frame 21A, vertical frames 23A, 24A).

[0121] Next, a sixth embodiment will be described with reference to Figs. 13 to 15. As shown in Fig. 13, a fitting 1A of the sixth embodiment is provided for an entrance, and as shown in Figs. 14 and 15, it is placed in an opening 101A formed in a building skeleton 100A. The fitting 1A comprises a door frame 7 and a door main body 8. The door main body 8 is placed within the door frame 7.

[0122] Adjacent to the fitting 1A, when viewed from the outside side X1, there are side structures 13A, 14A arranged adjacent to both sides of the fitting 1A in the left-right direction (horizontal direction). Exterior wall materials 93, 94 are arranged on the outside side X1 surfaces of the side structures 13A, 14A.

[0123] As shown in Figures 14 and 15, the door frame 7 is provided inside the opening 101A of the building skeleton 100A and is formed in a rectangular frame shape. The door frame 7 is framed in a rectangular shape by an upper frame (not shown), a lower frame (not shown), and left and right vertical frames 73, 74. A door main body 8 is arranged within the door frame 7 so that it can be opened and closed.

[0124] The door body 8 is formed in the shape of a rectangular plate. As shown in Figs. 13 and 14, the door body 8 is hung openably and closably on the outdoor side X1 (the front side in Fig. 13) via a hinge 81 provided on the vertical frame 73 side. As shown in Fig. 13, a handle 82 is attached to the door end side of the door body 8. As shown in Fig. 14, the hinge 81 rotatably supports the door body 8 on the hanging side of the door body 8.

[0125] As shown in Figures 14 and 15, opening 101A in building skeleton 100A is defined by an upper structure (not shown), a floor structure (not shown), and left and right side structures 13A, 14A. The side structures 13A, 14A include pillar members 131A, 141A. Structural plywood 110A is attached to the exterior side X1 of the pillar members 131A, 141A, and furring strips 120A for installing exterior wall materials 93, 94 are attached to the exterior side X1 surface of the structural plywood 110A on the outer periphery of the door frame 7.

[0126] The door frame 7 will now be described. In this embodiment, the configuration around the left and right vertical frames 73, 74 will be described. The main difference between the configuration around the left and right vertical frames 73, 74 is that an adjustment member 75 is arranged on the outer periphery of the protrusion 7422 of the vertical frame 74 arranged on the door edge side of the door body 8 (see FIG. 15), whereas no adjustment member is arranged on the outer periphery of the protrusion 7322 of the vertical frame 73 arranged on the hanging side of the door body 8 (see FIG. 14). In the following description of the left and right vertical frames 73, 74, common configurations will be described together, and different configurations will be described separately.

[0127] 14 and 15, the left and right vertical frames 73, 74 are fixed to the outer side X1 of the building skeleton 100A at the inner peripheral ends of the structural plywood 110A and the furring strips 120A. The vertical frames 73, 74 include inner frames 731, 741, outer frames 732, 742, and bridge members 733, 743 arranged between the inner frames 731, 741 and the outer frames 732, 742.

[0128] The indoor frame 731, 741 is disposed on the indoor side X2 of the vertical frames 73, 74 and has indoor hollow frames 7311, 7411 with rectangular hollow sections 7311a, 7411a in cross section. The indoor hollow frames 7311, 7411 extend in the vertical direction of the vertical frames 73, 74. The indoor frame 731, 741 is provided with vertical frame airtight material mounting sections 731a, 741a extending inward from the inner peripheral surface in the viewing direction, and airtight materials 731b, 741b attached to the outdoor side X1 of the vertical frame airtight material mounting sections 731a, 741a. The airtight materials 731b, 741b support the door body 8 without damaging it and ensure the airtightness of the door body 8.

[0129] The outdoor frames 732, 742 are arranged on the outdoor side X1 of the vertical frames 73, 74, and have outdoor hollow frames 7321, 7421 having rectangular hollow portions 7321a, 7421a extending in the forward direction when viewed in cross section, and protrusions 7322, 7422 protruding from the inner left-right ends of the outdoor hollow frames 7321, 7421 toward the outdoor side X1.

[0130] The outdoor hollow frames 7321, 7421 extend in the vertical direction of the vertical frames 73, 74. The outdoor frames 732, 742 are positioned away from the indoor frames 731, 741 on the outdoor side X1, and are connected to the indoor frames 731, 741 by bridge members 733, 743. The outdoor hollow frames 7321, 7421 of the outdoor frames 732, 742 are set to have a longer length in the projection direction (front-to-back direction in Figures 14 and 15) than the indoor hollow frames 7311, 7411 of the indoor frames 731, 741.

[0131] The protrusions 7322, 7422 are formed on the facing surfaces of the outside X1 sides of the vertical frames 73, 74 and protrude toward the outside X1 side. The protrusions 7322, 7422 are arranged laterally on the inner periphery in the left-right direction (facing direction) of the exterior wall materials 93, 94. The protrusions 7322, 7422 are formed to protrude toward the outside X1 from the inner periphery end of the facing surface of the end of the outside X1 side of the outdoor hollow frames 7321, 7421 (hollow frames) in the left-right direction, and protrude in the facing direction to the position of the surface of the outside X1 side of the exterior wall materials 93, 94. The protrusions 7322, 7422 protrude toward the outside X1 from the facing surfaces of the outside X1 sides of the vertical frames 73, 74 to a length in the facing direction that is the same as the thickness of the exterior wall materials 93, 94.

[0132] The protrusions 7322, 7422 are formed in the shape of a plate having a thickness in the left-right direction. Specifically, the protrusions 7322, 7422 are formed from a single flat, planar plate having only the thickness in the left-right direction (view direction) without a hollow portion, and extend in the view direction and the up-down direction.

[0133] When viewed from the front of the outside side X1, the visible surfaces 7322a, 7422a of the ends of the protrusions 7322, 7422 on the outside side X1 are formed as surfaces that have a width equal to the thickness of the plate thickness of the plate portion in the left-right direction and extend in the up-down direction, and are arranged so as to be exposed on the outside side X1. The protrusions 7322, 7422 are arranged so that the visible surfaces 7322a, 7422a formed by the end surfaces of the ends of the plate portions on the outside side X1 are exposed on the outside side X1. Only the end surfaces (visible surfaces 7322a, 7422a) of the outside side X1 of the plate thickness of the plate portions of the protrusions 7322, 7422 are exposed on the outside side X1.

[0134] The widths H731, H741 in the left-right direction (front direction) of the facing surfaces 7322a, 7422a exposed to the outside X1 at the ends of the protrusions 7322, 7422 on the outside side X1 are one-third or less of the widths H732, H742 in the left-right direction (front direction) at the ends of the outside side X1 of the outdoor hollow frames 7321, 7421. In this embodiment, the widths H731, H741 in the front direction of the facing surfaces 7322a, 7422a exposed to the outside side X1 of the protrusions 7322, 7422 are, for example, 1 to 3 mm.

[0135] As shown in Fig. 15, an adjustment member 75 is disposed on the outer periphery in the view direction of the protrusion 7422 of the vertical frame 74 of the vertical frames 73, 74. Note that, as shown in Fig. 14, no adjustment member is disposed on the outer periphery in the view direction of the protrusion 7322 of the vertical frame 73 of the vertical frames 73, 74.
