Description

本開示は、改装建具に関する。 This disclosure relates to refurbished building materials.

従来、建物躯体の開口部をリフォーム等で改装する方法として開口部に新たな建具を設置するカバー工法が採用されている。カバー工法において、建物躯体の開口部に設けられる既設枠と、既設枠の内周側に配置される新設枠と、既設枠と新設枠との間に配置されるアタッチメントと、を備える改装建具が知られている。 Conventionally, a covering method has been adopted for renovating openings in a building frame by installing new fixtures in the opening. In the covering method, a renovating fixture is known that includes an existing frame that is installed in the opening of the building frame, a new frame that is placed on the inner periphery of the existing frame, and an attachment that is placed between the existing frame and the new frame.

ところで、改装建具ではないが一般的な建具において、室外側に面格子(室外側構造物)が設けられる建具が知られている(例えば、特許文献1参照)。特許文献1に記載の建具において、面格子の横方向の両端部を固定するブラケットは、建物躯体に固定されている。 Incidentally, although not a remodeled fixture, a common fixture is known that has a grille (exterior structure) on the exterior side (see, for example, Patent Document 1). In the fixture described in Patent Document 1, brackets that secure both lateral ends of the grille are fixed to the building frame.

改装建具において、室外側に面格子を配置する場合に、特許文献1に記載の建具のように、面格子の横方向の両端部を建物躯体に固定する構造が一般的に採用されている。 When placing a grille on the exterior side of a renovated fixture, a structure in which both horizontal ends of the grille are fixed to the building frame, as in the fixture described in Patent Document 1, is generally used.

The main body side mounting bracket 73 has a main body side mounting plate 731 fixed to the mounting surface of the attachment vertical frame 43 side (room side X2) at the outer end in the left-right direction of the structure main body 71 with a screw 731a, a prospective direction extension plate 732 extending from the outer end in the left-right direction of the main body side mounting plate 731 to the attachment vertical frame 43 side in the prospective direction (room side X2), a prospective direction extension plate 733 extending inward in the left-right direction from the end of the prospective direction extension plate 732 on the attachment vertical frame 43 side (room side X2), and a mounting bracket side inclined plate 734 extending at an angle from the inner end in the left-right direction of the prospective direction extension plate 733 to the structure main body 71 side (room side X1).

枠側ブラケット74は、室内外方向に延びて形成され、室外側X1が、本体側取付金具73に固定されるとともに、室内側X2が、アタッチメント縦枠43のアタッチメント縦枠カバー部53に固定される。 The frame side bracket 74 is formed to extend in the indoor/outdoor direction, with the outdoor side X1 fixed to the main body side mounting bracket 73 and the indoor side X2 fixed to the attachment vertical frame cover part 53 of the attachment vertical frame 43.

枠側ブラケット74は、本体側取付金具73の取付金具側傾斜板734の室内側X2の傾斜面に沿って配置されネジ741aにより取付金具側傾斜板734に固定されるブラケット側傾斜板741と、ブラケット側傾斜板741の構造物本体71側の端部から室内側X2に屈曲して突出する傾斜突出片742と、ブラケット側傾斜板741のアタッチメント縦枠43側(室内側X2)の端部から左右方向の外側に延びるとともに本体側取付金具73の見付方向延出板733の室内側X2の面に沿って配置される見付方向延出板743と、見付方向延出板743の左右方向の外側の端部からアタッチメント縦枠43側(室内側X2)に延びる見込方向延在板744と、見込方向延在板744のアタッチメント縦枠43側(室内側X2)の端部から左右方向の内側に突出するフック状部745と、見込方向延在板744の室内外方向の途中の一部が切断されて左右方向の内側に倒されて屈曲して見付方向に延びる2つの屈曲板部746と、を有する。 The frame side bracket 74 is made up of a bracket side inclined plate 741 arranged along the inclined surface on the indoor side X2 of the mounting bracket side inclined plate 734 of the main body side mounting bracket 73 and fixed to the mounting bracket side inclined plate 734 with a screw 741a, an inclined protruding piece 742 that protrudes from the end of the bracket side inclined plate 741 on the structure main body 71 side and bends to the indoor side X2, and an inclined protruding piece 742 that extends outward in the left and right direction from the end of the bracket side inclined plate 741 on the attachment vertical frame 43 side (indoor side X2) and is fixed to the front side extension plate 733 of the main body side mounting bracket 73. It has a front-direction extending plate 743 arranged along the surface on the indoor side X2, a front-direction extending plate 744 extending from the outer left-right end of the front-direction extending plate 743 toward the vertical attachment frame 43 side (indoor side X2), a hook-shaped portion 745 protruding inward in the left-right direction from the end of the front-direction extending plate 744 on the vertical attachment frame 43 side (indoor side X2), and two bent plate portions 746 in which a portion of the front-direction extending plate 744 in the middle in the indoor/outdoor direction is cut off and tilted inward in the left-right direction, bending and extending in the front direction.

フック状部745は、枠側ブラケット74の室内側X2の端部に形成される。フック状部745は、見込方向延在板744の室内側X2の端部から左右方向の内側に屈曲して所定長さ延びる内側延在板7451と、内側延在板7451の左右方向の内側から室外側X1に屈曲して室外側X1に突出する突出板7452と、を有する。 The hook-shaped portion 745 is formed on the end of the frame-side bracket 74 on the indoor side X2. The hook-shaped portion 745 has an inner extension plate 7451 that bends inward in the left-right direction from the end of the indoor side X2 of the projection direction extension plate 744 and extends a predetermined length, and a protruding plate 7452 that bends from the inside of the left-right direction of the inner extension plate 7451 to the outdoor side X1 and protrudes to the outdoor side X1.

2つの屈曲板部746は、図5に示すように、見込方向延在板744の平面板状の部分の一部が室内側X2が開放するU字状に切断されて左右方向の内側に屈曲するように倒されることで、見込方向延在板744の室内外方向の途中から、左右方向の内側に突出して形成される。2つの屈曲板部746は、図4に示すように、フック状部745の室外側X1にフック状部745に対向して配置される。見込方向延在板744における2つの屈曲板部746が屈曲されて開放された部分には、2つの開口部744aが形成されている。 As shown in FIG. 5, the two bent plate sections 746 are formed by cutting a part of the flat plate-like portion of the projection direction extension plate 744 into a U-shape that opens on the indoor side X2 and tilting it so that it bends inward in the left-right direction from halfway in the indoor/outdoor direction of the projection direction extension plate 744. The two bent plate sections 746 are arranged opposite the hook-shaped portion 745 on the outdoor side X1 of the hook-shaped portion 745 as shown in FIG. Two openings 744a are formed in the part of the projection direction extension plate 744 where the two bent plate sections 746 are bent and opened.

枠側取付コ字状部材75は、左右方向の外側に向けて開放するコ字状部751と、コ字状部751の室内側X2の左右方向の外側において室内側X2に突出する屈曲突出部752と、を有する。コ字状部751は、室外側X1において見付方向に延びる室外側見付方向延在板部7511と、室外側見付方向延在板部7511の左右方向の内側の端部から室内外方向に延びる左右方向内側見込方向延在板部7512と、左右方向内側見込方向延在板部7512の室内側X2の端部から左右方向の外側に延びると共に室外側見付方向延在板部7511に平行に配置される室内側見付方向延在板部7513と、を有する。屈曲突出部752は、コ字状部751の室内側見付方向延在板部7513の左右方向の外側の端部から室内側X2に突出する。 The frame-side mounting U-shaped member 75 has a U-shaped portion 751 that opens outward in the left-right direction, and a bent protruding portion 752 that protrudes toward the indoor side X2 on the outside of the indoor side X2 of the U-shaped portion 751 in the left-right direction. The U-shaped portion 751 has an outdoor side facing direction extending plate portion 7511 that extends in the facing direction on the outdoor side X1, an indoor side facing direction extending plate portion 7512 that extends in the indoor-outdoor direction from the inner left-right end of the outdoor side facing direction extending plate portion 7511, and an indoor side facing direction extending plate portion 7513 that extends outward in the left-right direction from the indoor side X2 end of the indoor side facing direction extending plate portion 7512 and is arranged parallel to the outdoor side facing direction extending plate portion 7511. The bent protrusion 752 protrudes from the outer left and right ends of the interior facing direction extending plate portion 7513 of the U-shaped portion 751 toward the interior side X2.

枠側取付コ字状部材75は、コ字状部751の開放された部分の内部に枠側ブラケット74の2つの屈曲板部746が配置された状態で、枠側ブラケット74に取り付けられる。枠側取付コ字状部材75のコ字状部751の室外側見付方向延在板部7511と枠側ブラケット74の屈曲板部746とには、ネジ76が、室外側X1から室内側X2に向けて貫通して配置される。ネジ76の先端がコ字状部751の室内側見付方向延在板部7513の室外側X1の面に当接して配置された状態で、ネジ76をドライバー(図示せず)で回転させることで、枠側取付コ字状部材75は、室内外方向に移動する。 The frame-side mounting U-shaped member 75 is attached to the frame-side bracket 74 with the two bent plate portions 746 of the frame-side bracket 74 positioned inside the open portion of the U-shaped portion 751. A screw 76 is disposed penetrating the outdoor facing direction extending plate portion 7511 of the U-shaped portion 751 of the frame-side mounting U-shaped member 75 and the bent plate portion 746 of the frame-side bracket 74 from the outdoor side X1 toward the indoor side X2. With the tip of the screw 76 disposed in contact with the outdoor side X1 surface of the indoor side facing direction extending plate portion 7513 of the U-shaped portion 751, the screw 76 is rotated with a screwdriver (not shown) to move the frame-side mounting U-shaped member 75 in the indoor/outdoor direction.

コ字状部751の室内側見付方向延在板部7513の室内側X2の面とフック状部745の突出板7452の室外側X1の先端の端面との間に、構造物取付突出部535の見付方向延在部5351を配置した状態で、ネジ76をドライバー(図示せず)で回転させて枠側取付コ字状部材75を室内外方向に移動させる。これにより、コ字状部751の室内側見付方向延在板部7513の室内側X2の面とフック状部745の突出板7452の室外側X1の先端の端面との間に、構造物取付突出部535の見付方向延在部5351を挟み込んで、支持部72の枠側ブラケット74に、アタッチメント縦枠カバー部53の構造物取付突出部535の見付方向延在部5351を固定する。 With the view direction extension portion 5351 of the structure mounting protrusion 535 placed between the indoor side X2 surface of the indoor side view direction extension plate portion 7513 of the U-shaped portion 751 and the end face of the outdoor side X1 tip of the protruding plate 7452 of the hook-shaped portion 745, the screw 76 is rotated with a screwdriver (not shown) to move the frame side mounting U-shaped member 75 in the indoor/outdoor direction. As a result, the view direction extension portion 5351 of the structure mounting protrusion 535 is sandwiched between the indoor side X2 surface of the indoor side view direction extension plate portion 7513 of the U-shaped portion 751 and the end face of the outdoor side X1 tip of the protruding plate 7452 of the hook-shaped portion 745, and the view direction extension portion 5351 of the structure mounting protrusion 535 of the attachment vertical frame cover portion 53 is fixed to the frame side bracket 74 of the support portion 72.

これにより、枠側ブラケット74及び枠側取付コ字状部材75は、構造物取付突出部535を室内外方向に挟み込んで、室内外方向の移動を規制した状態で、構造物取付突出部535を固定する。枠側ブラケット74及び枠側取付コ字状部材75は、アタッチメント縦枠カバー部53の構造物取付突出部535を室内外方向に挟み込んで固定する固定部分70を構成する。 As a result, the frame side bracket 74 and the frame side mounting U-shaped member 75 clamp the structure mounting protrusion 535 in the indoor/outdoor direction, and fix the structure mounting protrusion 535 in a state where movement in the indoor/outdoor direction is restricted. The frame side bracket 74 and the frame side mounting U-shaped member 75 form the fixing part 70 that clamps and fixes the structure mounting protrusion 535 of the attachment vertical frame cover part 53 in the indoor/outdoor direction.

また、この状態においては、アタッチメント縦枠カバー部53の構造物取付突出部535の室内側突出片5352は、左右方向(見付方向)において、枠側取付コ字状部材75の屈曲突出部752とフック状部745の突出板7452との間に挟まれた位置に配置される。これにより、アタッチメント縦枠カバー部53の構造物取付突出部535の左右方向(見付方向)の移動が規制される。枠側取付コ字状部材75の屈曲突出部752及びフック状部745の突出板7452は、室内側突出片5352の左右方向(見付方向)の移動を規制する見付方向移動規制部を構成する。 In this state, the indoor protruding piece 5352 of the structure mounting protrusion 535 of the attachment vertical frame cover part 53 is positioned in a position sandwiched between the bent protruding part 752 of the frame side mounting U-shaped member 75 and the protruding plate 7452 of the hook-shaped part 745 in the left-right direction (visible direction). This restricts the left-right (visible direction) movement of the structure mounting protrusion 535 of the attachment vertical frame cover part 53. The bent protruding part 752 of the frame side mounting U-shaped member 75 and the protruding plate 7452 of the hook-shaped part 745 constitute a visible direction movement restriction part that restricts the left-right (visible direction) movement of the indoor protruding piece 5352.

次に、室外側構造物7をアタッチメント縦枠43のアタッチメント縦枠カバー部53に取り付ける手順について説明する。 Next, we will explain the procedure for attaching the exterior structure 7 to the attachment vertical frame cover portion 53 of the attachment vertical frame 43.

まず、室外側構造物7側において、構造物本体71の左右方向の端部に、支持部72の本体側取付金具73を固定する。 First, on the outdoor structure 7 side, the body side mounting brackets 73 of the support part 72 are fixed to the left and right ends of the structure body 71.

また、アタッチメント縦枠43のアタッチメント縦枠カバー部53側において、支持部72の枠側ブラケット74及び枠側取付コ字状部材75の間にアタッチメント縦枠43のアタッチメント縦枠カバー部53の構造物取付突出部535を配置した状態で、ネジ76を締め込むことで、枠側ブラケット74及び枠側取付コ字状部材75に、アタッチメント縦枠カバー部53の構造物取付突出部535を固定する。 In addition, with the structure mounting protrusion 535 of the attachment vertical frame cover part 53 of the attachment vertical frame 43 positioned between the frame side bracket 74 and the frame side U-shaped mounting member 75 of the support part 72 on the attachment vertical frame cover part 53 side of the attachment vertical frame 43, the structure mounting protrusion 535 of the attachment vertical frame cover part 53 is fixed to the frame side bracket 74 and the frame side U-shaped mounting member 75 by tightening the screw 76.

これにより、支持部72の枠側ブラケット74及び枠側取付コ字状部材75により、アタッチメント縦枠43のアタッチメント縦枠カバー部53の構造物取付突出部535を挟み込んで室内外方向の移動を規制した状態で固定できる。 As a result, the frame side bracket 74 and the frame side U-shaped mounting member 75 of the support part 72 clamp the structure mounting protrusion 535 of the vertical attachment frame cover part 53 of the vertical attachment frame 43, and fix it in a state where movement in the indoor and outdoor directions is restricted.

ネジ76を締め込んで固定する場合において、ネジ76を、アタッチメント縦枠43のアタッチメント縦枠カバー部53の構造物取付突出部535に対して、室外側X1から垂直に締め込んで固定する。枠側ブラケット74の見付方向延出板743には、ネジ76を締め込んで固定する際にドライバー(図示せず)が貫通する見込方向貫通穴743aが形成されている。 When tightening the screw 76 to fix the structure, the screw 76 is tightened vertically from the outside X1 into the structure mounting protrusion 535 of the attachment vertical frame cover part 53 of the attachment vertical frame 43. The front-facing extension plate 743 of the frame side bracket 74 has a front-facing through hole 743a through which a screwdriver (not shown) passes when tightening the screw 76 to fix the structure.

そして、構造物本体71の左右方向の端部に固定した本体側取付金具73と、枠側ブラケット74及び枠側取付コ字状部材75によりアタッチメント縦枠カバー部53の構造物取付突出部535を固定した状態の枠側ブラケット74とを、ネジ741aにより固定する。このようにして、室外側構造物7をアタッチメント縦枠43のアタッチメント縦枠カバー部53に取り付けることができる。 Then, the body side mounting brackets 73 fixed to the left and right ends of the structure body 71 and the frame side brackets 74, which have the structure mounting protrusions 535 of the attachment vertical frame cover part 53 fixed by the frame side brackets 74 and the frame side mounting U-shaped members 75, are fixed with screws 741a. In this way, the outdoor structure 7 can be attached to the attachment vertical frame cover part 53 of the attachment vertical frame 43.

本実施形態によれば、以下の効果が奏される。本実施形態の改装建具1は、建物躯体100の開口部11に設けられる既設枠2と、既設枠2の内周側に配置される新設枠3と、既設枠2及び新設枠3の間に配置されるアタッチメント4と、を備え、新設枠3の室外側X1に配置される室外側構造物7を備え、室外側構造物7は、構造物本体71と、構造物本体71の見付方向の端部に設けられアタッチメント縦枠43に取り付けられる支持部72と、を有し、アタッチメント縦枠43は、左右方向の外側に突出する構造物取付突出部535を有し、支持部72は、構造物取付突出部535を固定する固定部分70(枠側ブラケット74及び枠側取付コ字状部材75)を有する。これにより、構造物取付突出部535を、ネジ76により、支持部72の固定部分70(枠側ブラケット74及び枠側取付コ字状部材75)に容易に固定できる。よって、室外側X1に室外側構造物7が設けられる改装建具1において、室外側構造物7を建物躯体100に固定せずに容易に設置できる。 According to this embodiment, the following effects are achieved. The renovated fixture 1 of this embodiment includes an existing frame 2 provided in an opening 11 of a building structure 100, a new frame 3 arranged on the inner periphery of the existing frame 2, and an attachment 4 arranged between the existing frame 2 and the new frame 3. The fixture 1 also includes an exterior structure 7 arranged on the exterior side X1 of the new frame 3. The exterior structure 7 includes a structure body 71 and a support portion 72 provided at the end of the structure body 71 in the view direction and attached to the attachment vertical frame 43. The attachment vertical frame 43 has a structure mounting protrusion 535 that protrudes outward in the left-right direction, and the support portion 72 has a fixing portion 70 (frame side bracket 74 and frame side mounting U-shaped member 75) that fixes the structure mounting protrusion 535. This allows the structure mounting protrusion 535 to be easily fixed to the fixed portion 70 of the support part 72 (frame side bracket 74 and frame side mounting U-shaped member 75) with the screw 76. Therefore, in a remodeled fitting 1 in which an outdoor structure 7 is provided on the outdoor side X1, the outdoor structure 7 can be easily installed without being fixed to the building frame 100.

また、本実施形態においては、固定部分70(枠側ブラケット74及び枠側取付コ字状部材75)は、構造物取付突出部535を室内外方向に挟み込んで構造物取付突出部535を固定する。これにより、構造物取付突出部535を固定部分70(枠側ブラケット74及び枠側取付コ字状部材75)により室内外方向に挟み込んで、強固に固定できる。 In addition, in this embodiment, the fixing portion 70 (frame side bracket 74 and frame side U-shaped mounting member 75) clamps the structure mounting protrusion 535 in the indoor/outdoor direction to fix the structure mounting protrusion 535. As a result, the structure mounting protrusion 535 can be clamped in the indoor/outdoor direction by the fixing portion 70 (frame side bracket 74 and frame side U-shaped mounting member 75) and firmly fixed.

また、本実施形態においては、構造物取付突出部535は、見付方向に延びる見付方向延在部5351と、見付方向延在部5351の左右方向の外側の端部から室内側X2に突出する室内側突出片5352と、を有し、固定部分70は、室内側突出片5352の左右向の移動を規制する見付方向移動規制部(枠側取付コ字状部材75の屈曲突出部752、フック状部745の突出板7452)を有する。これにより、室内側突出片5352の左右向の移動を規制した状態で、構造物取付突出部535を、支持部72の固定部分70(枠側ブラケット74及び枠側取付コ字状部材75)に固定できる。 In this embodiment, the structure mounting protrusion 535 has a front-direction extending portion 5351 that extends in the front direction, and an interior protruding piece 5352 that protrudes from the outer end of the front-direction extending portion 5351 in the left-right direction toward the interior side X2, and the fixed portion 70 has a front-direction movement restricting portion (the bent protruding portion 752 of the frame-side mounting U-shaped member 75 and the protruding plate 7452 of the hook-shaped portion 745) that restricts the left-right movement of the interior protruding piece 5352. This allows the structure mounting protrusion 535 to be fixed to the fixed portion 70 of the support portion 72 (the frame-side bracket 74 and the frame-side mounting U-shaped member 75) while restricting the left-right movement of the interior protruding piece 5352.

また、本実施形態においては、アタッチメント縦枠43は、アタッチメント縦枠43の室外側X1に配置され新設縦枠33の室外側X1の少なくとも一部を覆うアタッチメント縦枠カバー部53を有し、構造物取付突出部535は、アタッチメント縦枠カバー部53の室外側X1において左右方向の外側に設けられる。これにより、アタッチメント縦枠カバー部53の室外側X1において左右方向の外側に設けられた構造物取付突出部535において、支持部72の固定部分70(枠側ブラケット74及び枠側取付コ字状部材75)に容易に固定できる。 In addition, in this embodiment, the attachment vertical frame 43 has an attachment vertical frame cover part 53 that is disposed on the outdoor side X1 of the attachment vertical frame 43 and covers at least a part of the outdoor side X1 of the newly installed vertical frame 33, and the structure mounting protrusion 535 is provided on the outside in the left-right direction on the outdoor side X1 of the attachment vertical frame cover part 53. This allows the structure mounting protrusion 535 provided on the outside in the left-right direction on the outdoor side X1 of the attachment vertical frame cover part 53 to be easily fixed to the fixing part 70 (frame side bracket 74 and frame side mounting U-shaped member 75) of the support part 72.

次に、図6により、第2実施形態の室外側構造物7Aの取付構造について説明する。第2実施形態において、上述の第1実施形態と同様の構成については、同一の符号を付して、その説明を省略する。 Next, the mounting structure of the outdoor structure 7A of the second embodiment will be described with reference to FIG. 6. In the second embodiment, the same components as those in the first embodiment described above are given the same reference numerals and their description will be omitted.

図6に示すように、第2実施形態の左右のアタッチメント縦枠43のアタッチメント縦枠カバー部53Aには、構造物取付突出部535A(外側突出部)が設けられる。構造物取付突出部535Aは、L字カバー部534の見付方向延在板534bの左右方向の外側の端部から左右方向の外側に延長するように延出して見付方向に延びる見付方向延在部5351を有する。第2実施形態の構造物取付突出部535Aは、第1実施形態の構造物取付突出部535と比べて、第1実施形態の構造物取付突出部535が室内側突出片5352を有しているのに対して、第1実施形態の室内側突出片5352を有していない。 As shown in FIG. 6, the vertical attachment frame cover portion 53A of the left and right vertical attachment frames 43 in the second embodiment is provided with a structure mounting protrusion 535A (outer protrusion). The structure mounting protrusion 535A has a facing direction extending portion 5351 that extends outward in the facing direction from the outer left-right end of the facing direction extending plate 534b of the L-shaped cover portion 534. Compared to the structure mounting protrusion 535 of the first embodiment, the structure mounting protrusion 535A of the second embodiment does not have the indoor side protrusion piece 5352 of the first embodiment, whereas the structure mounting protrusion 535 of the first embodiment has the indoor side protrusion piece 5352.

また、第2実施形態の支持部72Aは、本体側取付金具73と、枠側ブラケット74と、枠側取付コ字状部材75Aと、を有する。第2実施形態の本体側取付金具73及び枠側ブラケット74の構成は、上述の第1実施形態と同様である。第2実施形態の枠側取付コ字状部材75Aは、第1実施形態の枠側取付コ字状部材75と比べて、第1実施形態の枠側取付コ字状部材75が屈曲突出部752(見付方向移動規制部)を有しているのに対して、屈曲突出部752(見付方向移動規制部)を有していない。 The support portion 72A of the second embodiment has a main body side mounting bracket 73, a frame side bracket 74, and a frame side U-shaped mounting member 75A. The configurations of the main body side mounting bracket 73 and the frame side bracket 74 of the second embodiment are the same as those of the first embodiment. Compared to the frame side U-shaped mounting member 75 of the first embodiment, the frame side U-shaped mounting member 75A of the second embodiment does not have a bent protruding portion 752 (a portion restricting movement in the facing direction), whereas the frame side U-shaped mounting member 75 of the first embodiment has a bent protruding portion 752 (a portion restricting movement in the facing direction).

第2実施形態においても、第1実施形態と同様に、構造物取付突出部535Aにおいて、支持部72の固定部分70A(枠側ブラケット74及び枠側取付コ字状部材75A)に容易に固定できる。また、第2実施形態においても、第1実施形態と同様に、固定部分70A(枠側ブラケット74及び枠側取付コ字状部材75A)は、構造物取付突出部535を室内外方向に挟み込んで、室内外方向の移動を規制した状態で、構造物取付突出部535を固定する。これにより、構造物取付突出部535を固定部分70A(枠側ブラケット74及び枠側取付コ字状部材75A)により室内外方向に挟み込んで、強固に固定できる。 In the second embodiment, as in the first embodiment, the structure mounting protrusion 535A can be easily fixed to the fixed portion 70A (frame side bracket 74 and frame side mounting U-shaped member 75A) of the support portion 72. Also, in the second embodiment, as in the first embodiment, the fixed portion 70A (frame side bracket 74 and frame side mounting U-shaped member 75A) clamps the structure mounting protrusion 535 in the indoor/outdoor direction and fixes the structure mounting protrusion 535 in a state where movement in the indoor/outdoor direction is restricted. As a result, the structure mounting protrusion 535 can be clamped in the indoor/outdoor direction by the fixed portion 70A (frame side bracket 74 and frame side mounting U-shaped member 75A) and firmly fixed.
