Description
本開示は、建具が設けられる開口部における、支持金具、支持構造および建築物に関する。 This disclosure relates to support fittings, support structures, and buildings for openings where building fixtures are installed.
建築物は、ドア、扉、窓などの建具を有する。建具は、壁の開口部に設けられる。開口部は複数の部材によって構成される。開口部は上フレーム材を有する。上フレーム材は、結合部材によって上フレーム材の上方の梁と繋がる。結合部材は、上フレーム材を支持する。梁が撓んだ場合、結合部材を介して上フレーム材も撓む虞がある。特許文献１には、梁の撓みに起因して上フレーム材が撓むことを抑制するための支持構造が開示されている。同文献の支持構造は、胴差しと、まぐさと、胴差しとまぐさとを接続する建築金物と、によって構成される。建築金物は、胴差しとまぐさとの間の寸法変化に応じて上下寸法が変化するように構成される。 Buildings have fixtures such as doors, shutters, and windows. Fixtures are installed in openings in walls. Openings are made up of multiple components. The opening has an upper frame member. The upper frame member is connected to a beam above the upper frame member by a connecting member. The connecting member supports the upper frame member. If the beam bends, there is a risk that the upper frame member will also bend via the connecting member. Patent Document 1 discloses a support structure for preventing the upper frame member from bending due to the bending of the beam. The support structure in this document is made up of a girth, a lintel, and architectural hardware connecting the girth and lintel. The architectural hardware is configured so that its vertical dimensions change in response to dimensional changes between the girth and the lintel.
ところで、特許文献１の技術では、水平方向の力、または、横揺れに対して、支持構造が変形する虞がある。支持構造における上フレーム材が梁に対して横にずれると、建具の移動が妨げられる。このため、支持金具、支持構造および建築物に改善の余地がある。 However, with the technology described in Patent Document 1, there is a risk that the support structure will deform due to horizontal forces or lateral shaking. If the upper frame members of the support structure shift sideways relative to the beams, the movement of the fixtures will be hindered. For this reason, there is room for improvement in support fittings, support structures, and buildings.
（１）上記課題を解決する支持金具は、建具が設けられる開口部の上フレーム材と、前記上フレーム材の上方において延びる横架材との間に配置されて、かつ、前記上フレーム材と前記横架材とに繋がる支持金具であって、上下方向に弾性変形し、かつ、前記横架材の長手方向に沿う第１方向における剛性よりも、前記横架材の幅方向に沿う第２方向における剛性が大きいように構成される。この構成によれば、支持金具は上フレーム材と横架材との間に配置されて両部材に結合された状態で、支持金具は横架材の撓みに応じて変形するため、上フレーム材の変形を抑制できる。また、棒状の支持部材に比べて、横架材の幅方向における力に対して、横架材に対する上フレーム材のずれを抑制できる。横架材の幅方向における力の例としては、台風による風圧、地震に起因する振動、洪水による水圧、等が挙げられる。 (1) A support bracket that solves the above problem is positioned between an upper frame member of an opening where a fixture will be installed and a horizontal member extending above the upper frame member, and connects the upper frame member to the horizontal member. The support bracket is configured to elastically deform in the vertical direction and to have greater rigidity in a second direction along the width of the horizontal member than in a first direction along the longitudinal direction of the horizontal member. With this configuration, when the support bracket is positioned between the upper frame member and the horizontal member and connected to both members, the support bracket deforms in response to the deflection of the horizontal member, thereby suppressing deformation of the upper frame member. Furthermore, compared to rod-shaped support members, the support bracket can suppress displacement of the upper frame member relative to the horizontal member due to forces in the width direction of the horizontal member. Examples of forces in the width direction of the horizontal member include wind pressure from typhoons, vibrations caused by earthquakes, and water pressure from floods.
（２）上記（１）の支持金具において、前記横架材に固定される第１固定部と、前記上フレーム材に固定される第２固定部と、前記第１固定部と前記第２固定部とを繋ぐばね部と、を備え、前記ばね部は、上下方向に弾性変形し、かつ、前記第１方向における剛性よりも、前記第２方向における剛性が大きいように構成される。この構成によれば、支持金具は簡潔な構造であるため、製造し易い。 (2) The support bracket of (1) above includes a first fixed portion fixed to the cross member, a second fixed portion fixed to the upper frame member, and a spring portion connecting the first fixed portion and the second fixed portion, and the spring portion is configured to elastically deform in the vertical direction and to have greater rigidity in the second direction than in the first direction. With this configuration, the support bracket has a simple structure and is easy to manufacture.
（３）上記（２）の支持金具において、前記ばね部は、２個の板ばねを有し、前記支持金具が前記横架材と前記上フレーム材との間に配置される状態において、前記２個の板ばねは、前記第１方向に沿うように並べられる。この構成によれば、支持金具は、上フレーム材と横架材との間に配置されて両部材に結合された状態で、上フレーム材の支持強度を向上できる。 (3) In the support bracket described in (2) above, the spring portion has two leaf springs, and when the support bracket is positioned between the cross member and the upper frame member, the two leaf springs are aligned along the first direction. With this configuration, when the support bracket is positioned between the upper frame member and the cross member and connected to both members, it is possible to improve the support strength of the upper frame member.
（４）上記（３）の支持金具において、前記２個の板ばねは、前記２個の板ばねの間の間隔が上下方向の中間部で最も広がるように、互いに反対方向に、かつ、前記第１方向に突出するように湾曲する。この構成によれば、２個の板ばねの干渉を回避できる。 (4) In the support bracket described in (3) above, the two leaf springs are curved in opposite directions and protrude in the first direction so that the gap between the two leaf springs is widest at the center in the vertical direction. This configuration prevents interference between the two leaf springs.
（５）上記（２）の支持金具において、前記ばね部は、板ばねを有し、前記支持金具が前記横架材と前記上フレーム材との間に配置される状態において、前記板ばねは、前記板ばねの幅方向が前記第２方向に沿うように構成される。この構成によれば、支持金具が上フレーム材と横架材との間に配置されて両部材に結合された状態において、第２方向において横架材に対して上フレーム材のずれの発生を抑制できる。 (5) In the support bracket described in (2) above, the spring portion has a leaf spring, and when the support bracket is positioned between the cross member and the upper frame member, the leaf spring is configured so that its width direction is aligned with the second direction. With this configuration, when the support bracket is positioned between the upper frame member and the cross member and connected to both members, it is possible to prevent the upper frame member from shifting relative to the cross member in the second direction.
（６）上記（２）の支持金具において、前記ばね部は、複数のコイルばねによって構成され、前記支持金具が前記横架材と前記上フレーム材との間に配置される状態において、前記複数のコイルばねは、前記第２方向に沿って並べられる。この構成によれば、支持金具は簡潔な構造であるため、製造し易い。 (6) In the support bracket described in (2) above, the spring portion is composed of multiple coil springs, and when the support bracket is positioned between the cross member and the upper frame member, the multiple coil springs are aligned along the second direction. With this configuration, the support bracket has a simple structure and is therefore easy to manufacture.
（７）上記（２）～上記（６）のいずれか１つの支持金具において、前記第１固定部は、第１プレートと、前記横架材の第１ほぞ穴に挿通するものとして構成されて前記第１プレートから突出する第１ポールと、を備え、前記第２固定部は、第２プレートと、前記上フレーム材の第２ほぞ穴に挿通するものとして構成されて前記第２プレートから突出する第２ポールと、を備える。この構成によれば、支持金具を横架材および上フレーム材に固定し易い。 (7) In the support bracket of any one of (2) to (6) above, the first fixing portion comprises a first plate and a first pole configured to be inserted into a first mortise in the cross member and protruding from the first plate, and the second fixing portion comprises a second plate and a second pole configured to be inserted into a second mortise in the upper frame member and protruding from the second plate. This configuration makes it easy to fix the support bracket to the cross member and the upper frame member.
（８）上記課題を解決する支持構造は、建具が設けられる開口部の上フレーム材と、前記上フレーム材の上方において延びる横架材と、上記（１）～上記（７）のいずれか１つの支持金具とを備える。この構成によれば、支持金具が横架材の撓みに応じて変形するため上フレーム材の変形を抑制できる。また、横架材の幅方向における力に対して開口部の変形を抑制できる。 (8) A support structure that solves the above problem comprises an upper frame member for an opening in which a fixture is to be installed, a horizontal member extending above the upper frame member, and any one of the support fittings described in (1) to (7) above. With this configuration, the support fitting deforms in response to the deflection of the horizontal member, thereby suppressing deformation of the upper frame member. It also suppresses deformation of the opening due to a force applied in the width direction of the horizontal member.
（９）上記（８）の支持構造において、前記上フレーム材と前記横架材との間には、前記横架材の長手方向に沿って複数の支持部材が配置され、前記支持部材の少なくとも１つは、前記支持金具である。この構成によれば、支持金具は、開口部の変形を抑制できる。 (9) In the support structure described in (8) above, a plurality of support members are arranged between the upper frame member and the cross member along the longitudinal direction of the cross member, and at least one of the support members is the support bracket. With this configuration, the support bracket can suppress deformation of the opening.
（１０）上記課題を解決する建築物は、上記（９）の支持構造を備える。この構成によれば、建築物の開口部の変形を抑制できる。 (10) A building that solves the above problem is equipped with the support structure described in (9) above. This configuration can suppress deformation of the openings in the building.
本開示の支持金具、支持構造および建築物によれば、横架材の撓みに対して、かつ、水平方向の力または横揺れに対して、開口部の変形を抑制できる。 The support fittings, support structure, and building disclosed herein can suppress deformation of openings due to bending of cross members and horizontal forces or lateral shaking.

The cross member 7 is a member that constitutes the main body. The cross member 7 includes girder trusses 7A, beams, girders, and roof beams.
本実施形態では、開口部５は、横架材７としての胴差し７Ａの下に設けられる。開口部５には、掃き出し窓４Ａが設けられる。掃き出し窓４Ａは、サッシと、窓本体とを含む。掃き出し窓４Ａのサッシは開口部５に固定される。開口部５の上フレーム材６は、まぐさ６Ａとも呼ばれる。 In this embodiment, the opening 5 is provided below the girder 7A, which serves as the cross member 7. A sliding window 4A is provided in the opening 5. The sliding window 4A includes a sash and a window body. The sash of the sliding window 4A is fixed to the opening 5. The upper frame member 6 of the opening 5 is also called a lintel 6A.
本実施形態において、支持構造２は、掃き出し窓４Ａの上方に位置するまぐさ６Ａと、まぐさ６Ａの上方において延びる胴差し７Ａと、支持金具１とを備える。まぐさ６Ａと胴差し７Ａとの間には、胴差し７Ａの長手方向に沿って複数の支持部材１Ｘが配置される。 In this embodiment, the support structure 2 comprises a lintel 6A located above the French window 4A, a girth 7A extending above the lintel 6A, and a support bracket 1. Between the lintel 6A and the girth 7A, multiple support members 1X are arranged along the longitudinal direction of the girth 7A.

At least one of the support members 1X is a support bracket 1. In this embodiment, all of the multiple support members 1X are support brackets 1.
＜支持金具＞
図２および図３に示されるように、支持金具１は、開口部５のまぐさ６Ａと、まぐさ６Ａの上方において延びる胴差し７Ａとの間に配置される。支持金具１は、まぐさ６Ａと胴差し７Ａとに繋がる。本実施形態において、支持金具１は、胴差し７Ａに固定される第１固定部８と、まぐさ６Ａに固定される第２固定部９と、第１固定部８と第２固定部９とを繋ぐばね部１０と、を備える。
<Support bracket>
2 and 3, the support bracket 1 is disposed between the lintel 6A of the opening 5 and the girth 7A extending above the lintel 6A. The support bracket 1 is connected to the lintel 6A and the girth 7A. In this embodiment, the support bracket 1 includes a first fixed portion 8 fixed to the girth 7A, a second fixed portion 9 fixed to the lintel 6A, and a spring portion 10 connecting the first fixed portion 8 and the second fixed portion 9.
ばね部１０は、上下方向に弾性変形するように構成される。ばね部１０は、まぐさ６Ａと胴差し７Ａとの間の距離変化に応じて上下方向に弾性変形するように構成される。ばね部１０は、さらに、第１方向ＤＡにおける剛性よりも、第２方向ＤＢにおける剛性が大きいように構成される。なお、支持金具１の第１方向ＤＡおよび第２方向ＤＢは、支持金具１をまぐさ６Ａと胴差し７Ａとの間に配置した状態で、次のように定義される。第１方向ＤＡは、胴差し７Ａの長手方向に沿う方向である。第２方向ＤＢは、胴差し７Ａの幅方向に沿う方向である。本実施形態において、ばね部１０は、２個の板ばね１０Ａを有する。２個の板ばね１０Ａは底部で互いに結合する。２個の板ばね１０Ａのそれぞれは、１つの部材の部分として構成される。２個の板ばね１０Ａは、それぞれ別部材によって構成されてもよい。板ばね１０Ａの材料の例として、炭素鋼、ステンレス鋼、およびニッケル合金などが挙げられる。本実施形態の板ばね１０Ａは、ステンレス鋼によって構成される。 The spring portion 10 is configured to elastically deform in the vertical direction. The spring portion 10 is configured to elastically deform in the vertical direction in response to changes in the distance between the lintel 6A and the girth 7A. The spring portion 10 is further configured to have greater rigidity in the second direction DB than in the first direction DA. The first direction DA and second direction DB of the support bracket 1 are defined as follows when the support bracket 1 is positioned between the lintel 6A and the girth 7A: The first direction DA is the direction along the longitudinal direction of the girth 7A. The second direction DB is the direction along the width direction of the girth 7A. In this embodiment, the spring portion 10 has two leaf springs 10A. The two leaf springs 10A are connected to each other at their bottoms. Each of the two leaf springs 10A is configured as part of a single member. The two leaf springs 10A may also be configured as separate members. Examples of materials for the leaf spring 10A include carbon steel, stainless steel, and nickel alloy. In this embodiment, the leaf spring 10A is made of stainless steel.
２個の板ばね１０Ａは、支持金具１が胴差し７Ａとまぐさ６Ａとの間に配置される状態において、第１方向ＤＡに沿うように並べられる。また、板ばね１０Ａは、板ばね１０Ａの幅方向が第２方向ＤＢに沿うように構成される。また、２個の板ばね１０Ａは、２個の板ばね１０Ａの間の間隔が上下方向の中間部１１で最も広がるように、互いに反対方向に、かつ、第１方向ＤＡに突出するように湾曲する。 When the support bracket 1 is positioned between the girth 7A and the lintel 6A, the two leaf springs 10A are aligned along the first direction DA. The leaf springs 10A are configured so that their width direction is along the second direction DB. The two leaf springs 10A are curved in opposite directions and protrude in the first direction DA so that the gap between the two leaf springs 10A is widest at the middle portion 11 in the vertical direction.
図３および図４に示されるように、支持金具１の第１固定部８は、第１プレート１２と、第１プレート１２から突出する第１ポール１３と、を備える。第１ポール１３は、胴差し７Ａの第１ほぞ穴１４に挿通するものとして構成される。また、支持金具１の第２固定部９は、第２プレート１５と、第２プレート１５から突出する第２ポール１６と、を備える。第２ポール１６は、まぐさ６Ａの第２ほぞ穴１７に挿通するものとして構成される。 As shown in Figures 3 and 4, the first fixing portion 8 of the support bracket 1 includes a first plate 12 and a first pole 13 protruding from the first plate 12. The first pole 13 is configured to be inserted into a first mortise 14 of the girth 7A. The second fixing portion 9 of the support bracket 1 includes a second plate 15 and a second pole 16 protruding from the second plate 15. The second pole 16 is configured to be inserted into a second mortise 17 of the lintel 6A.
第１ポール１３は、第１ピン１８によって胴差し７Ａに固定される。本実施形態において、第１ピン１８はドリフトピンである。第１ポール１３には、第１ピン１８を通すための第１ピン孔１９が設けられる。第１ポール１３が第１ほぞ穴１４に挿通する状態において、胴差し７Ａが有する第１ピン挿入孔７Ｂは、第１ピン孔１９と繋がる。第１ピン１８は、第１ピン挿入孔７Ｂと第１ピン孔１９とに挿し込まれる。 The first pole 13 is fixed to the girth 7A by the first pin 18. In this embodiment, the first pin 18 is a drift pin. The first pole 13 has a first pin hole 19 for passing the first pin 18 through. When the first pole 13 is inserted into the first mortise 14, the first pin insertion hole 7B of the girth 7A connects with the first pin hole 19. The first pin 18 is inserted into the first pin insertion hole 7B and the first pin hole 19.
第２ポール１６は、第２ピン２０によってまぐさ６Ａに固定される。本実施形態において、第２ピン２０はドリフトピンである。第２ポール１６には、第２ピン２０を通すための第２ピン孔２１が設けられる。第２ポール１６が第２ほぞ穴１７に挿通する状態において、まぐさ６Ａが有する第２ピン挿入孔６Ｂは、第２ピン孔２１と繋がる。第２ピン２０は、第２ピン挿入孔６Ｂと第２ピン孔２１とに挿し込まれる。 The second pole 16 is fixed to the lintel 6A by a second pin 20. In this embodiment, the second pin 20 is a drift pin. The second pole 16 has a second pin hole 21 for passing the second pin 20 through. When the second pole 16 is inserted into the second mortise 17, the second pin insertion hole 6B of the lintel 6A connects with the second pin hole 21. The second pin 20 is inserted into the second pin insertion hole 6B and the second pin hole 21.
板ばね１０Ａは、板ばね１０Ａの剛性がまぐさ６Ａの剛性よりも小さくなるように構成される。具体的には、上下方向における圧縮に対する板ばね１０Ａの剛性は、まぐさ６Ａを上下方向に湾曲させる力に対する剛性よりも、小さい。これによって、まぐさ６Ａの湾曲を抑制できる。 The leaf spring 10A is configured so that its rigidity is less than that of the lintel 6A. Specifically, the rigidity of the leaf spring 10A against vertical compression is less than its rigidity against forces that cause the lintel 6A to bend in the vertical direction. This prevents the lintel 6A from bending.
板ばね１０Ａの板厚は、２ｍｍ以上１０ｍｍ以下である。支持金具１が胴差し７Ａとまぐさ６Ａとの間に配置される状態における板ばね１０Ａの上下方向の高さ（以下、板ばね１０Ａの設置高さ）は、１００ｍｍ以上５００ｍｍ以下である。第２方向ＤＢに沿う板ばね１０Ａの幅は、１２０ｍｍ以下である。 The thickness of the leaf spring 10A is 2 mm or more and 10 mm or less. The vertical height of the leaf spring 10A when the support bracket 1 is positioned between the girth 7A and the lintel 6A (hereinafter referred to as the installation height of the leaf spring 10A) is 100 mm or more and 500 mm or less. The width of the leaf spring 10A along the second direction DB is 120 mm or less.
板ばね１０Ａの弾性変形し易さは、板ばね１０Ａの材料および板ばね１０Ａの寸法を変更によって設定できる。板ばね１０Ａの構造は、支持金具１に求められる剛性に基づいて規定される。 The ease with which the leaf spring 10A elastically deforms can be adjusted by changing the material and dimensions of the leaf spring 10A. The structure of the leaf spring 10A is determined based on the rigidity required for the support bracket 1.
図５～図７を参照して、支持金具１を有する支持構造２について説明をする。図５および図６は、本実施形態の支持構造２と比較される比較対象の支持構造の正面図である。図７は、支持金具１が胴差し７Ａとまぐさ６Ａとの間に配置される状態の支持構造２の正面図である。図６および図７における胴差し７Ａの撓みは、撓みが見えやすいように強調されている。 The support structure 2 having the support bracket 1 will be described with reference to Figures 5 to 7. Figures 5 and 6 are front views of a comparative support structure that is compared to the support structure 2 of this embodiment. Figure 7 is a front view of the support structure 2 in which the support bracket 1 is positioned between the girth 7A and the lintel 6A. The deflection of the girth 7A in Figures 6 and 7 is emphasized to make the deflection easier to see.
図５および図６に示されるように、比較対象の支持構造では、胴差し７Ａとまぐさ６Ａとの間に支持部材１Ｙが配置されている。支持部材１Ｙは、束２２である。束２２は、短い柱であって、弾性を有していない。長期にわたって屋根の重みなどの荷重が加わり続けることに起因して、胴差し７Ａは撓む場合がある。この場合、胴差し７Ａの撓みに伴って、束２２を介して胴差し７Ａに繋がるまぐさ６Ａも撓む。まぐさ６Ａが撓むと開口部５が変形する。この結果、建具４（図１参照）の移動に支障が生じる。 As shown in Figures 5 and 6, in the comparative support structure, a support member 1Y is placed between the girth 7A and the lintel 6A. The support member 1Y is a beam 22. The beam 22 is a short pillar that is not elastic. The girth 7A may sag due to the continued application of loads such as the weight of the roof over a long period of time. In this case, as the girth 7A sags, the lintel 6A connected to the girth 7A via the beam 22 also sags. When the lintel 6A sags, the opening 5 deforms. As a result, the movement of the door and window fitting 4 (see Figure 1) is hindered.
胴差し７Ａの長手方向において、胴差し７Ａの撓みは、胴差し７Ａの端部よりも胴差し７Ａの中央部７Ｃの方が大きい。 In the longitudinal direction of the girth 7A, the deflection of the girth 7A is greater at the center 7C of the girth 7A than at the ends of the girth 7A.
図７に示されるように、本実施形態の支持構造２では、支持金具１は、胴差し７Ａとまぐさ６Ａとの間に配置される（図２参照）。支持金具１は、上下方向において、胴差し７Ａの撓み具合に応じて弾性変形する。具体的には、図７に示されるように、胴差し７Ａの端部の下方における支持金具１よりも、中央部７Ｃの下方における支持金具１の方が大きく変形する。 As shown in Figure 7, in the support structure 2 of this embodiment, the support bracket 1 is positioned between the girth 7A and the lintel 6A (see Figure 2). The support bracket 1 elastically deforms in the vertical direction depending on the degree of bending of the girth 7A. Specifically, as shown in Figure 7, the support bracket 1 below the center 7C of the girth 7A deforms more than the support bracket 1 below the ends.
本実施形態の作用を説明する。
支持金具１のばね部１０は、まぐさ６Ａと胴差し７Ａとの間の距離変化に応じて上下方向に弾性変形する。また、支持金具１のばね部１０は、第１方向ＤＡにおける剛性よりも、第２方向ＤＢにおける剛性が大きいように構成される。
The operation of this embodiment will be described.
The spring portion 10 of the support bracket 1 elastically deforms in the vertical direction in response to changes in the distance between the lintel 6A and the girth 7A. The spring portion 10 of the support bracket 1 is configured so that its rigidity in the second direction DB is greater than its rigidity in the first direction DA.
このため、支持金具１は、上下方向に弾性変形できる。これによって、支持金具１は、胴差し７Ａの幅方向に沿う力に対して開口部５の変形を抑制できる。また、建具４の開口部５は、上からの荷重だけでなく、開口部５を含む面に垂直な方向から力を受ける。例えば、建具４の開口部５には、台風の風圧の力が加わる。このとき、胴差し７Ａの幅方向に沿う力が支持金具１に加わる。支持金具１が、胴差し７Ａの幅方向に対して弱い場合、胴差し７Ａに対してまぐさ６Ａがずれることによって、開口部５が変形する虞がある。この点、上述のように、支持金具１のばね部１０は、第１方向ＤＡにおける剛性よりも、第２方向ＤＢにおける剛性が大きいように構成されている。このため、支持金具１は、胴差し７Ａの幅方向に沿う力、すなわち、第２方向ＤＢの力が加わる場合でも、胴差し７Ａからまぐさ６Ａがずれることを抑制できる。 This allows the support bracket 1 to elastically deform in the vertical direction. This allows the support bracket 1 to suppress deformation of the opening 5 due to a force acting along the width direction of the girth 7A. The opening 5 of the fitting 4 is subjected not only to loads from above, but also to forces perpendicular to the plane containing the opening 5. For example, the wind pressure of a typhoon acts on the opening 5 of the fitting 4. At this time, a force acting along the width direction of the girth 7A is applied to the support bracket 1. If the support bracket 1 is weak in the width direction of the girth 7A, the lintel 6A may shift relative to the girth 7A, potentially deforming the opening 5. In this regard, as described above, the spring portion 10 of the support bracket 1 is configured to have greater rigidity in the second direction DB than in the first direction DA. Therefore, the support bracket 1 can suppress displacement of the lintel 6A from the girth 7A even when a force acting along the width direction of the girth 7A, i.e., a force in the second direction DB, is applied.
また、支持金具１は次の作用を有する。長年の荷重によって胴差し７Ａは下に撓むことが知られている。このため、開口部５を有する外壁に設けられる胴差し７Ａについて、将来における胴差し７Ａの撓みによる撓み量が所定値に収まるように、胴差し７Ａの高さ寸法が規定される。または、開口部５を有する外壁に設けられる胴差し７Ａについて、胴差し７Ａの長手方向の長さが規定される。このように胴差し７Ａの高さ寸法が規定されるため、外壁の開口部５の上下方向の高さに設計上の限界がある。また、胴差し７Ａの長さが規定されるため、外壁の開口部５の幅方向の長さに限界がある。これに対して、本実施形態の支持構造２によれば、胴差し７Ａの湾曲が許容される。このため、胴差し７Ａの高さ寸法を小さくできる。または、胴差し７Ａの長手方向の長さを大きくできる。このようなことから、本実施形態の支持構造２によれば、開口部５の上下方向の高さを大きくできる。または、開口部５の幅方向の長さを大きくできる。 The support bracket 1 also has the following effect. It is known that girths 7A sag downward due to long-term load. For this reason, the height of girths 7A installed on an exterior wall having an opening 5 is specified so that the amount of sagging due to future sagging of the girths 7A remains within a predetermined value. Alternatively, the longitudinal length of girths 7A installed on an exterior wall having an opening 5 is specified. Because the height of girths 7A is specified in this way, there is a design limit to the vertical height of the opening 5 in the exterior wall. Furthermore, because the length of girths 7A is specified, there is a limit to the width of the opening 5 in the exterior wall. In contrast, the support structure 2 of this embodiment allows the girths 7A to bend. This allows the height of girths 7A to be reduced, or the longitudinal length of girths 7A to be increased. For these reasons, the support structure 2 of this embodiment allows the vertical height of the opening 5 to be increased, or the width of the opening 5 to be increased.
本実施形態の効果を説明する。
（１）支持金具１は、上下方向に弾性変形するように構成される。支持金具１は、胴差し７Ａの長手方向に沿う第１方向ＤＡにおける剛性よりも、胴差し７Ａの幅方向に沿う第２方向ＤＢにおける剛性が大きいように構成される。この構成によれば、支持金具１は、上下方向に弾性変形でき、かつ、第２方向ＤＢにおける剛性が大きいように構成される。この構成によれば、支持金具１はまぐさ６Ａと胴差し７Ａとの間に配置されて両部材に結合された状態で、支持金具１は胴差し７Ａの撓みに応じて変形するため、まぐさ６Ａの変形を抑制できる。また、棒状の支持部材に比べて、胴差し７Ａの幅方向における力に対して、胴差し７Ａに対するまぐさ６Ａのずれを抑制できる。胴差し７Ａの幅方向における力の例としては、台風による風圧、地震に起因する振動、洪水による水圧、等が挙げられる。
The effects of this embodiment will be described.
(1) The support bracket 1 is configured to elastically deform in the vertical direction. The support bracket 1 is configured so that its rigidity in the second direction DB, which is along the width direction of the girth 7A, is greater than its rigidity in the first direction DA, which is along the longitudinal direction of the girth 7A. With this configuration, the support bracket 1 can elastically deform in the vertical direction and is configured so that its rigidity in the second direction DB is greater. With this configuration, the support bracket 1 is positioned between the lintel 6A and the girth 7A and connected to both components, and the support bracket 1 deforms in response to the bending of the girth 7A, thereby suppressing deformation of the lintel 6A. Furthermore, compared to rod-shaped support members, it is possible to suppress displacement of the lintel 6A relative to the girth 7A in response to forces in the width direction of the girth 7A. Examples of forces in the width direction of the girth 7A include wind pressure from a typhoon, vibrations caused by an earthquake, and water pressure from a flood.
（２）支持金具１は、胴差し７Ａに固定される第１固定部８と、まぐさ６Ａに固定される第２固定部９と、第１固定部８と第２固定部９とを繋ぐばね部１０と、を備える。ばね部１０は、まぐさ６Ａと胴差し７Ａとの間の距離変化に応じて上下方向に弾性変形する。ばね部１０は、第１方向ＤＡにおける剛性よりも、第２方向ＤＢにおける剛性が大きいように構成される。この構成によれば、支持金具１は、ばね部１０を備える。このため、このように、支持金具１は、簡潔な構造であるため、製造し易い。 (2) The support bracket 1 comprises a first fixed portion 8 fixed to the girth 7A, a second fixed portion 9 fixed to the lintel 6A, and a spring portion 10 connecting the first fixed portion 8 and the second fixed portion 9. The spring portion 10 elastically deforms in the vertical direction in response to changes in the distance between the lintel 6A and the girth 7A. The spring portion 10 is configured to have greater rigidity in the second direction DB than in the first direction DA. With this configuration, the support bracket 1 comprises the spring portion 10. As such, the support bracket 1 has a simple structure and is easy to manufacture.
（３）支持金具１のばね部１０は、２個の板ばね１０Ａを有する。２個の板ばね１０Ａは、第１方向ＤＡに沿うように並べられる。この構成によれば、支持金具１は、まぐさ６Ａと胴差し７Ａとの間に配置されて両部材に結合された状態で、まぐさ６Ａの支持強度を向上できる。具体的には、ばね部１０が１個の板ばね１０Ａを有する場合に比べて、まぐさ６Ａが胴差し７Ａに強く結合されるため、まぐさ６Ａは、建具４の開閉において振動し難くなる。これによってまぐさ６Ａの劣化が抑制されるため、建具４の円滑な開閉を長期にわたって維持できる。 (3) The spring portion 10 of the support bracket 1 has two leaf springs 10A. The two leaf springs 10A are aligned along the first direction DA. With this configuration, the support bracket 1 is positioned between the lintel 6A and the girth 7A and connected to both components, improving the support strength of the lintel 6A. Specifically, compared to when the spring portion 10 has a single leaf spring 10A, the lintel 6A is more strongly connected to the girth 7A, making the lintel 6A less likely to vibrate when the door fixture 4 is opened or closed. This suppresses deterioration of the lintel 6A, allowing the door fixture 4 to open and close smoothly over a long period of time.
（４）２個の板ばね１０Ａは、２個の板ばね１０Ａの間の間隔が上下方向の中間部１１で最も広がるように、互いに反対方向に、かつ第１方向ＤＡに突出するように湾曲する。この構成によれば、２個の板ばね１０Ａは、互いに反対方向に、かつ、第１方向ＤＡに突出するように湾曲する。 (4) The two leaf springs 10A are curved in opposite directions and protrude in the first direction DA so that the gap between the two leaf springs 10A is widest at the middle portion 11 in the vertical direction. According to this configuration, the two leaf springs 10A are curved in opposite directions and protrude in the first direction DA.
仮に、２個の板ばね１０Ａが、２個の板ばね１０Ａの間の間隔が上下方向の中間部１１で最も狭くなるように、互いに反対方向に、かつ第１方向ＤＡに突出するように湾曲した場合、板ばね１０Ａが圧縮したときに、２個の板ばね１０Ａが干渉する虞がある。この点で、上記構成によれば、２個の板ばね１０Ａの干渉を回避できる。 If the two leaf springs 10A were curved in opposite directions and protruding in the first direction DA so that the gap between the two leaf springs 10A was narrowest at the vertical middle portion 11, there is a risk that the two leaf springs 10A would interfere with each other when compressed. In this regard, the above configuration makes it possible to avoid interference between the two leaf springs 10A.
（５）板ばね１０Ａは、支持金具１が胴差し７Ａとまぐさ６Ａとの間に配置される状態において、板ばね１０Ａの幅方向が第２方向ＤＢに沿うように構成される。この構成によれば、支持金具１がまぐさ６Ａと胴差し７Ａとの間に配置されて両部材に結合された状態において、第２方向ＤＢにおいて胴差し７Ａに対してまぐさ６Ａのずれの発生を抑制できる。 (5) The leaf spring 10A is configured so that the width direction of the leaf spring 10A aligns with the second direction DB when the support bracket 1 is positioned between the girth 7A and the lintel 6A. This configuration prevents the lintel 6A from shifting relative to the girth 7A in the second direction DB when the support bracket 1 is positioned between the lintel 6A and the girth 7A and connected to both components.
（６）第１固定部８は、第１プレート１２と、第１プレート１２から突出する第１ポール１３と、を備える。第１ポール１３は、胴差し７Ａの第１ほぞ穴１４に挿通するものとして構成される。第２固定部９は、第２プレート１５と、第２プレート１５から突出する第２ポール１６と、を備える。第２ポール１６は、まぐさ６Ａの第２ほぞ穴１７に挿通するものとして構成される。この構成によれば、支持金具１を胴差し７Ａおよびまぐさ６Ａに固定し易い。 (6) The first fixing part 8 comprises a first plate 12 and a first pole 13 protruding from the first plate 12. The first pole 13 is configured to be inserted into a first mortise 14 in the girth 7A. The second fixing part 9 comprises a second plate 15 and a second pole 16 protruding from the second plate 15. The second pole 16 is configured to be inserted into a second mortise 17 in the lintel 6A. This configuration makes it easy to fix the support bracket 1 to the girth 7A and the lintel 6A.
（７）支持構造２は、掃き出し窓４Ａが設けられる開口部５のまぐさ６Ａと、まぐさ６Ａの上方において延びる胴差し７Ａと、支持金具１とを備える。この構成によれば、支持金具１が胴差し７Ａの撓みに応じて変形するためまぐさ６Ａの変形を抑制できる。また、胴差し７Ａの幅方向における力に対して開口部５の変形を抑制できる。 (7) The support structure 2 comprises a lintel 6A for the opening 5 in which the sliding window 4A is provided, a girth 7A extending above the lintel 6A, and a support bracket 1. With this configuration, the support bracket 1 deforms in response to the bending of the girth 7A, thereby suppressing deformation of the lintel 6A. Furthermore, deformation of the opening 5 due to the force of the girth 7A in the width direction can be suppressed.
（８）建築物３において、まぐさ６Ａと胴差し７Ａとの間には、胴差し７Ａの長手方向に沿って複数の支持部材１Ｘが配置される。支持部材１Ｘの少なくとも１つは、支持金具１である。この構成によれば、支持金具１によって、開口部５の変形を抑制できる。 (8) In the building 3, multiple support members 1X are arranged between the lintel 6A and the girth 7A along the longitudinal direction of the girth 7A. At least one of the support members 1X is a support bracket 1. With this configuration, the support bracket 1 can suppress deformation of the opening 5.
本実施形態では、複数の支持部材１Ｘは全て支持金具１である。他の例では、まぐさ６Ａと胴差し７Ａとの間において、胴差し７Ａの撓み量が大きいところに支持金具１が配置される。そして、胴差し７Ａの撓み量がわずかであるところに、支持部材１Ｘとしての束が配置される。 In this embodiment, all of the multiple support members 1X are support brackets 1. In another example, the support brackets 1 are placed between the lintel 6A and the girth 7A, where the amount of deflection of the girth 7A is large. Then, the bundle of support members 1X is placed where the amount of deflection of the girth 7A is small.
（９）建築物３は、支持構造２を備える。この構成によれば、建築物３の開口部５の変形を抑制できる。 (9) The building 3 is equipped with a support structure 2. This configuration can suppress deformation of the opening 5 of the building 3.
＜変形例＞
上記実施形態は、支持金具１、支持構造２、および建築物３が取り得る形態の例示であり、その形態を制限することを意図していない。支持金具１、支持構造２、および建築物３は、上記実施形態に例示された形態とは異なる形態を取り得る。その一例は、実施形態の構成の一部を置換、変更、もしくは、省略した形態、または、実施形態に新たな構成を付加した形態である。以下に実施形態の変形例の一例を示す。
<Modification>
The above-described embodiment is an example of the possible forms of the support bracket 1, the support structure 2, and the building 3, and is not intended to limit the forms. The support bracket 1, the support structure 2, and the building 3 may take forms different from those illustrated in the above-described embodiment. Examples of such forms include forms in which part of the configuration of the embodiment is replaced, modified, or omitted, or forms in which a new configuration is added to the embodiment. An example of a modified embodiment is shown below.
・図８に示されるように、支持金具１のばね部１０は、複数のコイルばね１０Ｂによって構成される。支持金具１が胴差し７Ａとまぐさ６Ａとの間に配置される状態において、複数のコイルばね１０Ｂは、第２方向ＤＢに沿って並べられる。複数のコイルばね１０Ｂは、第１方向ＤＡに沿って並べられてもよい。また、複数のコイルばね１０Ｂは、複数の列を成してもよい。本変形例において、４個のコイルばね１０Ｂが、第１固定部８と第２固定部９とを繋ぐように配置されている。４個のコイルばね１０Ｂは、第２方向ＤＢに沿って２列に並んでいる。コイルばね１０Ｂは、支持金具１において、胴差し７Ａの長手方向に沿う第１方向ＤＡにおける剛性よりも、胴差し７Ａの幅方向に沿う第２方向ＤＢにおける剛性が大きくなるように構成される。例えば、複数のコイルばね１０Ｂは、第１方向ＤＡにおける剛性よりも、胴差し７Ａの幅方向に沿う第２方向ＤＢにおける剛性が大きくなるように、第１プレート１２に配置されてもよい。また、異なる材料によって、それぞれのコイルばね１０Ｂを形成してもよい。また、それぞれのコイルばね１０Ｂの寸法を変えてもよい。 - As shown in Figure 8, the spring portion 10 of the support bracket 1 is composed of multiple coil springs 10B. When the support bracket 1 is positioned between the girth 7A and the lintel 6A, the multiple coil springs 10B are arranged along the second direction DB. The multiple coil springs 10B may also be arranged along the first direction DA. The multiple coil springs 10B may also form multiple rows. In this modified example, four coil springs 10B are arranged to connect the first fixed portion 8 and the second fixed portion 9. The four coil springs 10B are arranged in two rows along the second direction DB. The coil springs 10B are configured so that the rigidity of the support bracket 1 in the second direction DB along the width direction of the girth 7A is greater than the rigidity in the first direction DA along the longitudinal direction of the girth 7A. For example, the multiple coil springs 10B may be arranged on the first plate 12 so that their rigidity in the second direction DB, which is along the width direction of the girth 7A, is greater than their rigidity in the first direction DA. Furthermore, each coil spring 10B may be made of a different material. Furthermore, the dimensions of each coil spring 10B may be different.
この構成によれば、支持金具１は、第２方向ＤＢに沿って並べられる複数のコイルばね１０Ｂを備える。支持金具１は簡潔な構造であるため、製造し易い。 With this configuration, the support bracket 1 includes multiple coil springs 10B arranged along the second direction DB. The support bracket 1 has a simple structure and is therefore easy to manufacture.
・本実施形態の支持構造２において、まぐさ６Ａに配置される支持金具１の板ばね１０Ａは、支持金具１の配置場所によって、異なる材料によって構成されてもよい。 - In the support structure 2 of this embodiment, the leaf spring 10A of the support bracket 1 placed on the lintel 6A may be made of different materials depending on the location of the support bracket 1.
・本実施形態の支持構造２において、まぐさ６Ａに配置される支持金具１の板ばね１０Ａは、支持金具１の配置場所によって、他の支持金具１と異なる寸法となるように構成されてもよい。 - In the support structure 2 of this embodiment, the leaf spring 10A of the support bracket 1 placed on the lintel 6A may be configured to have different dimensions from other support brackets 1 depending on the placement location of the support bracket 1.
・支持構造２において、支持金具１と係合する延長部材をさらに備えてもよい。延長部材は、支持金具１とまぐさ６Ａとの間に配置される。延長部材は、延長部材の長手方向に沿うように支持金具１の第１ポール１３を挿通させる孔を有してもよい。例えば、延長部材は束である。この束によって、支持金具１の長さを調整することができる。 - The support structure 2 may further include an extension member that engages with the support bracket 1. The extension member is positioned between the support bracket 1 and the lintel 6A. The extension member may have a hole through which the first pole 13 of the support bracket 1 is inserted along the longitudinal direction of the extension member. For example, the extension member may be a bundle. The length of the support bracket 1 can be adjusted by using this bundle.
・支持金具１は、支持金具１が配置される場所に応じて、上下方向における弾性が変わるように構成されてもよい。例えば、まぐさ６Ａの中央部７Ｃに配置される支持金具１は、まぐさ６Ａの端部に配置される支持金具１よりも板ばね１０Ａが圧縮変形し易いように構成されてもよい。 - The support bracket 1 may be configured so that its elasticity in the vertical direction changes depending on where the support bracket 1 is placed. For example, the support bracket 1 placed in the center portion 7C of the lintel 6A may be configured so that the leaf spring 10A is more susceptible to compressive deformation than the support bracket 1 placed at the end of the lintel 6A.
・本実施形態では、支持構造２に関する本技術は、掃き出し窓４Ａの開口部５のまぐさ６Ａに適用されているが、本技術は、他の建具の開口部５における上フレーム材６の支持構造にも適用できる。例えば、支持構造２は、玄関扉の開口部５の上フレーム材６における支持構造に適用できる。ビルドインガレージのシャッターの開口部５の上フレーム材６における支持構造にも適用できる。 - In this embodiment, the technology related to the support structure 2 is applied to the lintel 6A of the opening 5 of the French window 4A, but this technology can also be applied to the support structure of the upper frame member 6 of the opening 5 of other building materials. For example, the support structure 2 can be applied to the support structure of the upper frame member 6 of the opening 5 of a front door. It can also be applied to the support structure of the upper frame member 6 of the opening 5 of a built-in garage shutter.
