[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. As shown in Figures 1 and 2, in a structure 10 around an entrance of a first embodiment, a fixture 1 is a remodeling fixture for remodeling in which a new door frame 3 is attached to an existing door frame 2 in a state where the existing door frame 2 is attached to an opening 101 (see Figure 2) of a building skeleton 100.

[0009] As shown in Fig. 1, the fixture 1 is a door such as an entrance door, and is fitted into an opening 101 (see Fig. 2) formed in a building skeleton 100. In this embodiment, the fixture 1 is a remodeled door, and comprises an existing door frame 2 (see Fig. 2), a new door frame 3, and a door body 4 as a door element. The new door frame 3 is attached to the inner periphery of the existing door frame 2.

[0010] The door body 4 is made of a rectangular plate material and is placed inside the new door frame 3. The door body 4 is attached so as to open and close the opening 101. The door body 4 is hung openably on the outside of the room (the front side in the drawing) via hinges 41. A handle 42 is attached to the leading edge of the door body 4.

[0011] As shown in FIG. 1, in a structure 10 around an entranceway, a wall 11 is arranged adjacent to a door frame 1. A floor 15 is arranged below the door frame 1. When viewed from the outside, the wall 11 has side wall portions 12 arranged adjacent to both sides of the door frame 1 in the left-right direction (horizontal direction), and an upper wall portion 13 arranged adjacent to the top of the door frame 1. An exterior wall material 6 is arranged on the exterior surface of the wall 11. As shown in FIG. 2, the exterior wall material 6 is attached to the exterior side of the wall 11 via multiple furring strips 541, 542, and 543. The exterior wall material 6 is composed of multiple panels made of, for example, metal siding and having a predetermined thickness. Panels made of metal siding are lighter than panels made of ceramic siding.

[0012] As shown in Fig. 3, the exterior wall material 6 is attached to the side wall portion 12 of the wall portion 11 by a mounting structure 50 for the exterior wall material 6. In the mounting structure 50 for the exterior wall material 6, the exterior wall material 6 is attached to a furring strip 543 attached to a mounting surface 531 of the base portion 53, with the lower end portion 61 of the exterior wall material 6 supported by a starter 55. In explaining the mounting structure 50 for the exterior wall material 6, when the side wall portion 12 of the wall portion 11 is viewed from the front on the outside side as shown in Figs. 1 and 2, the front-to-back direction that is the direction in which the fitting 1 is viewed is referred to as the depth direction, and in the depth direction, the left side in Fig. 3 and the left front side in Fig. 4 are referred to as the "front side," and the right side in Fig. 3 and the right rear side in Fig. 4 are referred to as the "rear side."

[0013] As shown in Fig. 3, the configuration of side wall portion 12 of wall portion 11 is such that structural plywood 110 is attached to the exterior side of building skeleton 100, and multiple existing furring strips 120 used to install existing door frame 2 are attached to the exterior side of structural plywood 110 around the outer periphery of existing door frame 2. Existing exterior wall materials 130 are then placed on the exterior side of the multiple existing furring strips 120, and during renovation, multiple furring strips 541, 542, 543 are fixed to the exterior side of existing exterior wall material 130, as shown in Fig. 2, and exterior wall material 6 is attached to the multiple furring strips 541, 542, 543.

[0014] As shown in FIG. 2, multiple furring strips 541, 542, 543 are attached to the exterior surface of the existing exterior wall material 130 on the outer periphery of the new door frame 3. The furring strip 541 is a horizontal furring strip formed in a plate shape that is wide in the vertical direction and thick in the depth direction and extends horizontally near the upper outer periphery of the new door frame 3. The pair of furring strips 542 are arranged on both left and right ends of the existing exterior wall material 130 on both sides of the new door frame 3, and are vertical furring strips formed in a plate shape that is wide in the horizontal direction and thick in the depth direction and extends vertically. The furring strips 543 are arranged in a row in the vertical direction between the pair of furring strips 542, and are horizontal furring strips formed in a plate shape that is wide in the vertical direction and thick in the depth direction and extends horizontally.

[0015] As shown in Figure 3, the mounting structure 50 for the exterior wall material 6 comprises a foundation portion 51, a base portion 52 arranged on top of the foundation portion 51, a substructure portion 53 including the base portion 52 and having a mounting surface 531 extending in the vertical direction, a furring strip 543 attached to the mounting surface 531 of the substructure portion 53, a starter 55 fixed to the furring strip 543, a spacer member 56 arranged between the starter 55 and the foundation portion 51 on the lower side of the starter 55, and an exterior wall material 6 attached to the furring strip 543 with its lower end positioned on the starter 55.

[0016] In this embodiment, the exterior wall material 6 is an exterior wall material used for renovation. In this embodiment, the exterior wall material 6 is attached so as to cover the outer surface of an existing exterior wall material 130 that has already been installed during renovation.

[0017] In this embodiment, as shown in Figure 3, the base portion 53 is configured to include a base portion 52, and is configured as a wall in which existing exterior wall material 130 is attached via existing furring strips 120 to structural plywood 110 provided on the surface of the building skeleton 100 including the base portion 52. Furring strips 543 are fixed to mounting surfaces 531 on the surface of the wall of the base portion 53 including the base portion 52. The existing exterior wall material 130 is positioned above the foundation portion 51. Below the existing exterior wall material 130, an existing flashing material 140 is attached to the outdoor surface of the structural plywood 110.

[0018] The existing water-repellent material 140 has a crank-shaped mounting plate 141 that extends in the vertical direction and is fixed to the structural plywood 110, an inclined plate 142 that extends a predetermined length from the lower end of the mounting plate 141 at a downward slope toward the outside of the room, and a downward extension plate 143 that extends a predetermined length downward from the outside end of the inclined plate 142.

[0019] The starter 55 is arranged on the lower end side of the existing exterior wall material 130. The starter 55 is arranged so as to cover the front portion of the foundation portion 51. The starter 55 is fixed to the furring strip 543 at a position where the exterior wall material 6 and the starter 55 cover more than 80% of the entire height of the foundation portion 51 from the upper end of the foundation portion 51 downward on the outer surface of the foundation portion 51. The starter 55 is fixed to the furring strip 543a arranged at the lowest of the multiple furring strips 543 at a position where the exterior wall material 6 and the starter 55 cover more than 80% of the outer surface of the foundation portion 51. Therefore, the exterior wall material 6 and the starter 55 cover more than 80% of the entire height of the foundation portion 51 from the upper end of the foundation portion 51 downward on the outer surface of the foundation portion 51.

[0020] As a result, the line of sight of a person standing in front of the fitting 1 or the wall portion 11 is positioned at a higher position, and therefore the entire outer surface of the foundation portion 51 in the vertical direction is covered by the exterior wall material 6 and cannot be seen from the line of sight of a person standing in front of the fitting 1 or the wall portion 11, making the foundation portion 51 less visible and improving the design. The exterior wall material 6 and the starter 55 may cover the entire outer surface of the foundation portion 51 in the vertical direction. The starter 55 may be fixed to the furring strip 543 at a position where the exterior wall material 6 and the starter 55 cover the entire outer surface of the foundation portion 51 in the vertical direction.

[0021] The starter 55 has a vertically extending portion 551 that extends in the vertical direction, and a support portion 552 that is provided at the lower end of the vertically extending portion 551 and that receives and supports the lower end of the exterior building material 6.

[0022] As shown in Figure 4, the vertical extension portion 551 is formed in a plate shape and is arranged in the left-right direction in an area spanning a part of the lower side of the furring strip 543a attached to the lower end of the existing exterior wall material 130 and the lower ends of a pair of furring strips 542, and its upper side is fixed to the lower side of the furring strip 543a attached to the lower end of the existing exterior wall material 130 by fastening member 551a, and its lower end extends to the vicinity of the lower end of the foundation portion 51.

[0023] The vertical extension portion 551 is disposed along the outdoor surface of a spacer member 56 attached to the outdoor surface of the foundation portion 51. The spacer member 56 is disposed below the starter 55, between the lower end of the vertical extension portion 551 of the starter 55 and the foundation portion 51. As the spacer member 56, for example, a spacer formed from a foam material or a spacer formed from a highly weather-resistant rubber-based material can be used.

[0024] The reason for providing the spacer member 56 will be explained. The lower side of the starter 55 is disposed in a position facing the base portion 51, and there is no member supporting the back surface of the lower side of the starter 55. Therefore, the spacer member 56 is disposed on the lower side of the starter 55, between the lower end of the vertically extending portion 551 of the starter 55 and the base portion 51. This makes it possible to prevent the lower side of the starter 55 from wobbling, and to prevent the lower side of the starter 55 from hitting the base portion 51.

[0025] As shown in Figures 4 and 5, the support portion 552 is formed at the lower end (lower part) of the starter 55. The support portion 552 accommodates and supports the lower end portion 61 of the exterior building material 6. The support portion 552 is formed in a frame shape that opens upward and extends in the left-right direction. The support portion 552 has a stepped bottom portion 553 with a two-step structure and a front standing plate 554.

[0026] The front standing plate 554 rises upward from the front end of the stepped bottom surface portion 553. The upper end of the front standing plate 554 is located higher than the upper step portion 553a of the stepped bottom surface portion 553. The upper end of the front standing plate 554 is formed with a folded portion 554a that is folded back toward the rear side.

[0027] The stepped bottom surface portion 553 has an upper step portion 553a disposed on the rear side, and a lower step portion 553c connected to the front end of the upper step portion 553a via a step 553b.

[0028] The upper step portion 553a is formed in the shape of a plate that has a thickness in the vertical direction, a width in the depth direction, and extends in the left-right direction. The width in the depth direction from the rear end of the upper step portion 553a to the front standing plate 554 is formed to be slightly larger than the thickness of the exterior building material 6. The lower end portion 61 of the exterior building material 6 is arranged on the upper surface of the upper step portion 553a. When the lower end portion 61 of the exterior building material 6 is arranged on the upper surface of the upper step portion 553a, it is arranged between the vertical extension portion 551 and the front standing plate 554 and is supported by the support portion 552. A step 553b is connected to the front end portion of the upper step portion 553a.

[0029] The step 553b extends downward a predetermined distance from the front end of the upper portion 553a. The step 553b is formed in a plate shape that has a thickness in the front-rear direction, a width in the up-down direction, and extends in the left-right direction. The lower end of the step 553b is connected to the lower portion 553c.

[0030] The lower portion 553c extends a predetermined length from the lower end of the step 553b toward the front. The lower portion 553c is formed in a plate shape that has a thickness in the up-down direction, a width in the depth direction, and extends in the left-right direction. The lower portion 553c is located lower than the upper portion 553a.

[0031] When the lower end 61 of the exterior building material 6 is arranged in the upper step 553a, the lower step 553c is arranged below the lower end of the exterior building material 6. When the lower end 61 of the exterior building material 6 is arranged in the upper step 553a, water such as rainwater that flows from above to below along the exterior building material 6 flows into the lower step 553c.

[0032] A drain hole 553d is formed in the lower portion 553c (lower plate). The drain hole 553d penetrates the plate portion of the lower portion 553c in the up-down direction. By providing the drain hole 553d in the lower portion 553c, water that flows into the lower portion 553c is discharged to the outside through the drain hole 553d.

[0033] The front end of the lower stage portion 553c is connected to the lower end of the front standing plate 554. The width of the lower stage portion 553c in the depth direction is smaller than the distance between the vertical extending portion 551 and the front standing plate 554.

[0034] When the lower end 61 of the exterior wall material 6 of the starter 55 is placed on the upper surface of the upper part 553a of the support part 552, the surface of the front standing plate 554 is exposed to the outside of the room, as shown in Figure 1. The surface of the front standing plate 554, which is the part of the starter 55 exposed to the outside of the room, has the same type of external design as either or both of the surface of the door body 4 of the fitting 1 and the surface of the exterior wall material 6.

[0035] As a result, the surface of the front standing plate 554 of the starter 55 and either or both of the surface of the door body 4 and the surface of the exterior wall material 6 of the fitting 1 are unified with the same type of exterior design, so the appearance seen from outside the room has the same texture or the same color tone. Therefore, a unified design can be realized.

[0036] In this embodiment, the "exterior design" refers to the appearance or design of the exterior. "Having the same type of exterior design" means, for example, when the overall design of the appearance is unified or when the texture of the appearance is very similar. For example, the surface of the front standing plate 554 of the starter 55 and either or both of the surface of the door body 4 and the surface of the exterior wall material 6 of the fitting 1 can be surface-treated, such as by wrapping, to have the same type of exterior design, or by attaching a wrapping sheet to the surface to have the same type of exterior design.

[0037] The mounting structure 50 for the exterior wall material 6 of this embodiment described above provides the following effects. The mounting structure 50 for the exterior wall material 6 of this embodiment includes a foundation portion 51, a base portion 52 arranged on top of the foundation portion 51, a substrate portion 53 including the base portion 52 and having a mounting surface 531 extending in the vertical direction, furring strips 543 attached to the mounting surface 531, starters 55 fixed to the furring strips 543, and an exterior wall material 6 attached to the furring strips 543 with its lower end positioned on the starter 55. The exterior wall material 6 and starter strips 55 cover more than 80% of the entire height of the foundation portion 51 on the outer surface of the foundation portion 51, from the upper end of the foundation portion 51 downward. This allows the exterior wall material 6 and starter strips 55 to cover more than 80% of the entire height of the foundation portion 51 on the outer surface of the foundation portion 51, from the upper end of the foundation portion 51 downward, making the outer surface of the foundation portion 51 less visible and improving design.

[0038] In this embodiment, the exterior wall material 6 is metal siding. Metal siding is a lightweight exterior wall material, so it is easy to handle, and the lightweight exterior wall material 6 made of metal siding can be easily supported by the starter 55.

[0039] Furthermore, in this embodiment, the surface of the front standing plate 554, which is the portion of the starter 55 exposed to the outside on the outdoor side, has the same type of exterior design as at least one or both of the surface of the door body 4 of the fitting 1 and the surface of the exterior wall material 6. As a result, the surface of the front standing plate 554 of the starter 55 and one or both of the surface of the door body 4 of the fitting 1 and the surface of the exterior wall material 6 are unified with the same type of exterior design, and therefore the appearance seen from the outdoor side has the same texture or the same color tone. Therefore, a unified design can be achieved.

[0040] In this embodiment, the starter 55 has a support portion 552 formed at the bottom, which is open upward and accommodates and supports the lower end portion 61 of the exterior building material 6. This allows the starter 55 to reliably support the lower end portion 61 of the exterior building material 6 with a simple configuration.

[0041] In this embodiment, the support portion 552 has an upper stage portion 553a on which the lower end portion 61 of the exterior building material 6 is disposed, and a lower stage portion 553c disposed below the lower end portion 61 of the exterior building material 6. As a result, water such as rainwater flowing from above to below along the exterior building material 6 flows into the lower stage portion 553c, and thus the water such as rainwater can be temporarily stored in the lower stage portion 553c.

[0042] In this embodiment, drainage holes 553d are formed in the lower portion 553c (lower surface plate) of the support portion 552. This allows water that has flowed into the lower portion 553c to be easily discharged to the outside through the drainage holes 553d.

[0043] Furthermore, in this embodiment, a spacer member 56 is provided that is arranged between the starter 55 and the base portion 51 on the lower side of the starter 55. By arranging the spacer member 56 on the lower side of the starter 55 between the lower end of the vertically extending portion 551 of the starter 55 and the base portion 51, it is possible to prevent the lower side of the starter 55 from wobbling and to prevent the lower side of the starter 55 from hitting the base portion 51.

[0044] Next, a second embodiment will be described with reference to Fig. 6. The mounting structure 50A for an exterior wall material 6A of the second embodiment differs mainly in that the furring strips 742 are fixed to the entrance floor 15 via L-shaped metal fittings 76, and in the configuration of the starter 75 and the exterior wall material 6A. In the description of the second embodiment, components similar to those of the first embodiment are given the same reference numerals, and their description will be omitted.

[0045] As shown in Figure 6, the mounting structure 50A for the exterior wall material 6A of the second embodiment comprises a foundation portion 71, a base portion 72 arranged on top of the foundation portion 71, a subfloor portion 73 including the base portion 72 and having a mounting surface 731 extending in the vertical direction, furring strips 741, 742 attached to the mounting surface 731 of the subfloor portion 73 and arranged side by side above and below, a starter 75 fixed to the furring strip 742 arranged below, and an exterior wall material 6A attached to the furring strips 741, 742 with its lower end positioned on the starter 75.

[0046] In this embodiment, the exterior wall material 6A is an exterior wall material used for renovation. In this embodiment, the exterior wall material 6A is attached so as to cover the outer surface of an existing exterior wall material 130 that has already been installed during renovation.

[0047] In this embodiment, as shown in Figure 6, the base portion 73 is composed of a wall that includes a base portion 72 and has existing exterior wall material 130 attached to the surface of the building structure 100 including the base portion 72 via existing furring strips 120.

[0048] The existing exterior wall material 130 is positioned above the foundation 71. An existing water flashing material 140A is attached to the outdoor surface of the base 72 below the existing exterior wall material 130. The existing water flashing material 140A was cut off midway because it was getting in the way during the renovation.

[0049] Upper furring strips 741 are fixed to mounting surface 731 on the surface of the wall of base portion 73, including sill portion 72. The upper furring strips 741 are fixed to mounting surface 731 of base portion 73 by fastening members 741a, such as screws, penetrating from the outdoor side of the upper furring strips 741 through the upper furring strips 741, the existing exterior wall material 130, and the existing furring strips 120 in that order, until the tips of the fastening members 741a, such as screws, reach the outdoor side of base portion 72.

[0050] The lower furring strip 742 is fixed to the floor 15 via an L-shaped metal fitting 76. The L-shaped metal fitting 76 has a vertical plate 761 that extends in the up-down direction, and a horizontal plate 762 that extends from the lower end of the vertical plate 761 toward the outside of the room. The vertical plate 761 is arranged along the back surface of the lower furring strip 742. The lower furring strip 742 is fixed to the vertical plate 761 with fastening members 742a such as two screws. The horizontal plate 762 is arranged along the upper surface of the floor 15, and is fixed to the floor 15 with fastening members 762a such as bolts.

[0051] The starter 75 is fixed to the exterior surface at the lower portion of the lower furring strip 742. The starter 75 is positioned so as to cover the front portion of the foundation 71. The starter 75 is fixed to the lower furring strip 742 at a position where the starter 75 and the exterior wall material 6A cover more than 80% of the entire height of the foundation 71 on the outer surface of the foundation 71, from the upper end of the foundation 71 downward. Therefore, the exterior wall material 6A and the starter 75 cover more than 80% of the entire height of the foundation 71 on the outer surface of the foundation 71, from the upper end of the foundation 71 downward.

[0052] As a result, the line of sight of a person standing in front of the fitting 1 or the wall portion 11 is positioned at a higher position, and therefore the entire outer surface of the starter 75 and the foundation portion 71 is covered in the vertical direction by the exterior wall material 6A and cannot be seen from the line of sight of a person standing in front of the fitting 1 or the wall portion 11, making the foundation portion 71 less visible and improving the design. The exterior wall material 6A and the starter 75 may cover the entire outer surface of the foundation portion 71 in the vertical direction. The starter 75 may be fixed to the lower furring strip 742 or the upper furring strip 741 in a position where the exterior wall material 6A and the starter 75 cover the entire outer surface of the foundation portion 71 in the vertical direction.

[0053] The starter 75 has a vertical extension portion 751 that extends in the vertical direction, a support portion 752 that is provided on the lower end side of the vertical extension portion 751 and supports the lower end portion of the exterior wall material 6A, and a drain portion 755 that is provided below the support portion 752.

[0054] As shown in Figure 6, the vertically extending portion 751 is formed in a plate shape, is arranged along the outdoor surface of the lower furring strip 742, and is fixed to the outdoor surface of the lower furring strip 742 with fastening members 751a. The support portion 752 is formed at the lower end (lower part) of the vertically extending portion 751 of the starter 75. The support portion 752 supports the lower end of the exterior building material 6A. The support portion 752 is formed in a frame shape that opens upward and extends in the left-right direction.

[0055] The support portion 752 has a protruding plate 753 that protrudes a predetermined length from the lower end of the vertically extending portion 751 toward the outside of the room, and a front standing plate 754 that rises upward from the outside end of the protruding plate 753. An opening 65 that is formed at the lower end of the exterior building material 6A and opens downward is arranged on the front standing plate 754. As a result, the opening 65 at the lower end of the exterior building material 6A is supported by the front standing plate 754 of the support portion 752, and the lower end of the exterior building material 6A is supported by the starter 75.

[0056] The drain portion 755 is formed in a crank shape and has a connecting plate 755a that extends downward from the lower end of the vertical extending portion 751, an inclined plate 755b that extends a predetermined length from the lower end of the connecting plate 755a to the outside of the room at a downward slope, and a downward extending plate 755c that extends a predetermined length downward from the outside end of the inclined plate 755b.

[0057] According to the mounting structure 50A for the exterior wall material 6A of the second embodiment described above, as in the first embodiment, the exterior wall material 6A and the starter 75 can cover more than 80% of the entire height of the foundation part 71 from the upper end of the foundation part 71 downward on the outer surface of the foundation part 71, making the outer surface of the foundation part 51 less visible and improving the design.

[0058] In this embodiment, the starter 75 has a support portion 752 formed at the bottom, which opens upward and supports the lower end of the exterior building material 6A. As a result, similar to the first embodiment, the starter 75 can reliably support the lower end of the exterior building material 6A with a simple configuration.

[0059] Next, a third embodiment will be described with reference to Fig. 7. While the mounting structure 50 for the exterior wall material 6 of the first embodiment is applied to renovations, the mounting structure 50B for the exterior wall material 6B of the third embodiment is applied to new constructions. In the description of the third embodiment, the same components as those of the first embodiment are given the same reference numerals, and their description will be omitted.

[0060] 7, the mounting structure 50B for an exterior wall material 6B of the third embodiment comprises a foundation portion 81, a base portion 82 arranged on top of the base portion 81, a substrate portion 83 including the base portion 82 and having a mounting surface 831 extending in the vertical direction, furring strips 84 attached to the mounting surface 831 of the substrate portion 83, a starter 85 fixed to the furring strips 84, a spacer member 86 arranged below the starter 85 between the starter 85 and the foundation portion 81, and an exterior wall material 6B attached to the furring strips 84 with its lower end positioned on the starter 85.

Therefore, the exterior wall material 6B and the starter 85 cover more than 80% of the entire height of the foundation portion 81 from the upper end of the foundation portion 81 downward on the outer surface of the foundation portion 81.

[0063] As a result, the line of sight of a person standing in front of the fitting 1 or the wall portion 11 is positioned at a higher position, and therefore the entire outer surface of the foundation portion 81 in the vertical direction is covered by the exterior wall material 6B and cannot be seen from the line of sight of a person standing in front of the fitting 1 or the wall portion 11, making the foundation portion 81 less visible and improving the design. The exterior wall material 6B and the starter 85 may cover the entire outer surface of the foundation portion 81 in the vertical direction. The starter 85 may be fixed to the furring strip 84 at a position where the exterior wall material 6B and the starter 85 cover the entire outer surface of the foundation portion 81 in the vertical direction.

[0064] The starter 85 has a vertically extending portion 851 that extends in the vertical direction, and a support portion 852 that is provided at the lower end of the vertically extending portion 851 and that receives and supports the lower end of the exterior building material 6B.

[0065] As shown in Figure 7, the vertical extension portion 851 is formed in a plate shape, and its upper side is fixed to the mounting surface 831 of the base portion 83, which is composed of the wall of the structural plywood 110, by a fastening member 851a, and its lower end extends to near the lower end of the foundation portion 81.

[0066] The vertically extending portion 851 is disposed along the outdoor surface of a spacer member 86 attached to the outdoor surface of the foundation portion 81. The spacer member 86 is disposed below the starter 85, between the lower end of the vertically extending portion 851 of the starter 85 and the foundation portion 81. As the spacer member 86, for example, a spacer formed from a foam material or a spacer formed from a highly weather-resistant rubber-based material can be used. The reason for providing the spacer member 86 is the same as the reason for providing the spacer member 56 in the first embodiment.

[0067] The configuration of the support portion 852 of the third embodiment is similar to the configuration of the support portion 552 of the first embodiment, and therefore the description of the first embodiment will be used and the description thereof will be omitted.

[0068] The mounting structure 50B for the exterior wall material 6B of the third embodiment described above can achieve the same effects as those of the first embodiment. Specifically, the mounting structure 50B for the exterior wall material 6B of the third embodiment can cover 80% or more of the entire height of the foundation part 81 from the upper end of the foundation part 81 downward on the outer surface of the foundation part 81 with the exterior wall material 6B and the starter 85, making the outer surface of the foundation part 81 less visible and improving the design.

[0069] In this embodiment, the starter 85 has a support portion 852 formed at the bottom, which is open upward and accommodates and supports the lower end portion 61 of the exterior building material 6B. As a result, similar to the first embodiment, the starter 85 can reliably support the lower end portion 61 of the exterior building material 6B with a simple configuration.

[0070] Next, a fourth embodiment will be described with reference to Fig. 8. The fourth embodiment differs from the second embodiment in that, whereas in the second embodiment shown in Fig. 6, furring strips 742 are fixed to the entrance floor 15 via L-shaped metal fittings 76, furring strips 743 are fixed to the foundation 71 of the building skeleton 100. In the description of the fourth embodiment, the same components as those in the second embodiment are given the same reference numerals, and their description will be omitted.
