Description
本発明は、構造部が被覆部に覆われた構造部材に外部取付部材を固定する固定構造に関する。 The present invention relates to a fixing structure for fixing an external attachment member to a structural member whose structural portion is covered by a covering portion.
柱材や梁材などの構造部材においては、例えば特許文献１のように、木材などの耐火性の低い構造部を石膏材などの耐火性の高い被覆部で被覆することにより耐火性が高められる。こうした構造部材に外装材などの外部取付部材が取り付けられる場合、その外部取付部材は固定部材を介して構造部材に固定される。固定部材は、構造部材に設けられたアンカーボルトにナットを螺合させることにより構造部材に固定される。 In structural members such as pillars and beams, fire resistance can be improved by covering structural parts with low fire resistance, such as wood, with covering parts with high fire resistance, such as gypsum, as in Patent Document 1, for example. When an external mounting member such as an exterior material is attached to such a structural member, the external mounting member is fixed to the structural member via a fixing member. The fixing member is fixed to the structural member by screwing a nut onto an anchor bolt provided on the structural member.
しかしながら、上述した固定部材においては、被覆部に押し付けられるような外力が作用したときに、その外力が被覆部に直接的に伝達される。このため、被覆部が壊れやすい場合に用いることができなかった。 However, when an external force is applied to the fixing member described above, the external force is directly transmitted to the covering. For this reason, it cannot be used when the covering is fragile.
上記課題を解決する固定構造は、構造部が被覆部で被覆された構造部材と、前記構造部材に外部取付部材を固定する固定部材と、を有する固定構造であって、前記被覆部は、第１平面と、前記第１平面に交差する第２平面と、前記第１平面と前記第２平面とが交差する交差端と、を有し、前記固定部材は、前記第１平面に対向する第１平面対向部と、前記第２平面に対向する第２平面対向部と、前記第１平面対向部と前記第２平面対向部とを接続して前記交差端で折れ曲がる折曲部と、前記外部取付部材が固定される固定部と、前記第１平面対向部および前記第２平面対向部の少なくとも一方を前記構造部に接続する接続部と、を有する。これにより、固定部材に作用する外力が構造部に伝達されるため、該外力が被覆部に伝達されにくくなる。 The fixing structure that solves the above problem includes a structural member whose structural portion is covered with a covering portion, and a fixing member that fixes an external attachment member to the structural member, the covering portion having a first plane, a second plane that intersects with the first plane, and an intersection end where the first plane and the second plane intersect, and the fixing member has a first plane facing portion that faces the first plane, a second plane facing portion that faces the second plane, a bending portion that connects the first plane facing portion and the second plane facing portion and bends at the intersection end, a fixing portion to which the external attachment member is fixed, and a connecting portion that connects at least one of the first plane facing portion and the second plane facing portion to the structural member. As a result, an external force acting on the fixing member is transmitted to the structural portion, and the external force is less likely to be transmitted to the covering portion.
上記構成の固定構造において、前記接続部は、前記第１平面対向部を前記構造部に接続する第１接続部と、前記第２平面対向部を前記構造部に接続する第２接続部と、を有することが好ましい。これにより、固定部材に作用する外力が各平面対向部において被覆部に伝達されにくくなる。 In the fixing structure having the above configuration, it is preferable that the connection portion has a first connection portion that connects the first plane facing portion to the structural portion, and a second connection portion that connects the second plane facing portion to the structural portion. This makes it difficult for an external force acting on the fixing member to be transmitted to the covering portion at each plane facing portion.
上記構成の固定構造において、前記第１接続部は、前記第１平面対向部の法線方向に前記被覆部を貫通して前記構造部に接続され、前記第１平面対向部を前記第１平面側から支持する第１圧縮用接続材と、前記第１平面対向部の法線方向に前記第１平面対向部および前記被覆部を貫通して前記構造部に接続され、前記第１平面対向部を基準とした前記第１平面の反対側から前記第１平面対向部を支持する第１引張用接続材と、を有することが好ましい。 In the fixing structure of the above configuration, it is preferable that the first connection portion has a first compression connection material that is connected to the structural part by penetrating the covering part in the normal direction of the first plane opposing part and supports the first plane opposing part from the first plane side, and a first tension connection material that is connected to the structural part by penetrating the first plane opposing part and the covering part in the normal direction of the first plane opposing part and supports the first plane opposing part from the opposite side of the first plane with respect to the first plane opposing part.
これにより、第１平面対向部を第１平面に押し付けようとする力を第１圧縮用接続材を介して構造部に伝達し、第１平面対向部を第１平面から引き離そうとする力を第１引張用接続材を介して構造部に伝達することができる。 This allows the force that presses the first plane facing portion against the first plane to be transmitted to the structural part via the first compression connecting member, and the force that pulls the first plane facing portion away from the first plane to be transmitted to the structural part via the first tension connecting member.
上記構成の固定構造において、前記第２接続部は、前記第２平面対向部の法線方向に前記被覆部を貫通して前記構造部に接続され、前記第２平面対向部を前記第２平面側から支持する第２圧縮用接続材と、前記第２平面対向部の法線方向に前記第２平面対向部および前記被覆部を貫通して前記構造部に接続され、前記第２平面対向部を基準とした前記第２平面の反対側から前記第２平面対向部を支持する第２引張用接続材と、を有することが好ましい。 In the fixing structure of the above configuration, it is preferable that the second connection portion has a second compression connection material that is connected to the structural part by penetrating the covering part in the normal direction of the second plane opposing part and supports the second plane opposing part from the second plane side, and a second tension connection material that is connected to the structural part by penetrating the second plane opposing part and the covering part in the normal direction of the second plane opposing part and supports the second plane opposing part from the opposite side of the second plane with respect to the second plane opposing part.
これにより、第２平面対向部を第２平面に押し付けようとする力を第２圧縮用接続材を介して構造部に伝達し、第２平面対向部を第２平面から引き離そうとする力を第２引張用接続材を介して構造部材に伝達することができる。 This allows the force pressing the second plane facing portion against the second plane to be transmitted to the structural member via the second compression connecting member, and the force pulling the second plane facing portion away from the second plane to be transmitted to the structural member via the second tension connecting member.
上記構成の固定構造において、前記第１平面が鉛直面であってもよい。これにより、鉛直方向に延びる平面を有する構造部材に対して外部取付部材を固定することができる。
上記構成の固定構造において、前記平面が水平面であってもよい。これにより、水平方向に延びる平面を有する構造部材に対して外部取付部材を固定することができる。
In the fixing structure having the above configuration, the first plane may be a vertical plane, whereby the external mounting member can be fixed to a structural member having a plane extending in the vertical direction.
In the fixing structure having the above configuration, the plane may be a horizontal plane, whereby the external mounting member can be fixed to a structural member having a plane extending in the horizontal direction.
上記構成の固定構造において、前記第１平面と前記第２平面とが直交していてもよい。これにより、四角柱状の構造部材に外部取付部材を固定することができる。 In the fixing structure of the above configuration, the first plane and the second plane may be perpendicular to each other. This allows the external attachment member to be fixed to the rectangular prism-shaped structural member.
図１～図７を参照して、固定構造の一実施形態について説明する。
図１に示すように、構造部材１０は、木材などの耐火性の低い構造部１１を石膏材などの耐火性の高い被覆部１２で覆うことにより耐火性が高められる。こうした構造部材１０に対しては、カーテンウォールなどの外装材といった外部取付部材１３が固定部材１５によって固定される。
An embodiment of the fixing structure will be described with reference to FIGS.
As shown in Fig. 1, the fire resistance of a structural member 10 is enhanced by covering a structural part 11 having low fire resistance such as wood with a covering part 12 having high fire resistance such as gypsum material. An external mounting member 13 such as an exterior material such as a curtain wall is fixed to the structural member 10 by a fixing member 15.
図２に示すように、被覆部１２は、第１平面１６、第２平面１７、および、交差端１８を有している。第１平面１６は、外部取付部材１３に臨むように配置される面であり、構造部材１０の側面を構成する水平面である。第２平面１７は、第１平面１６の端部で第１平面１６に直交する面であり、構造部材１０の背面を構成する鉛直面である。交差端１８は、第１平面１６と第２平面１７とが交差する部分であり、第１平面１６と第２平面１７とによって構成される角部である。固定部材１５は、構造部材１０の各所において被覆部１２の第１平面１６と第２平面１７とに対向するように配設される固定具１９を有している。 2, the covering portion 12 has a first plane 16, a second plane 17, and an intersecting end 18. The first plane 16 is a surface arranged to face the external mounting member 13, and is a horizontal surface constituting the side surface of the structural member 10. The second plane 17 is a surface perpendicular to the first plane 16 at the end of the first plane 16, and is a vertical surface constituting the back surface of the structural member 10. The intersecting end 18 is a portion where the first plane 16 and the second plane 17 intersect, and is a corner portion formed by the first plane 16 and the second plane 17. The fixing member 15 has a fixing device 19 arranged at each point of the structural member 10 so as to face the first plane 16 and the second plane 17 of the covering portion 12.
図３に示すように、固定具１９は、外部取付部材１３が固定される固定部２０のほか、第１平面対向部２１、第２平面対向部２２、および、折曲部２３を有している。
第１平面対向部２１は、平板状をなしており、構造部材１０に固定具１９が固定された状態において、被覆部１２の第１平面１６の一部に対向するように配設される。この第１平面対向部２１には、後述する第１引張用接続材３２が貫通する複数の第１貫通孔２４が形成されている。各第１貫通孔２４は、第１引張用接続材３２の頭部を収容可能な座繰り付きの孔である。
As shown in FIG. 3 , the fixture 19 has a fixing portion 20 to which the external mounting member 13 is fixed, as well as a first planar facing portion 21 , a second planar facing portion 22 , and a bent portion 23 .
The first plane facing portion 21 has a flat plate shape and is disposed so as to face a part of the first plane 16 of the covering portion 12 in a state in which the fastener 19 is fixed to the structural member 10. A plurality of first through holes 24 through which first tension connecting members 32 described below pass are formed in the first plane facing portion 21. Each of the first through holes 24 is a countersunk hole capable of accommodating the head of the first tension connecting member 32.
第２平面対向部２２は、第１平面対向部２１と同じ幅を有するとともに第１平面対向部２１よりも短い平板状をなしており、構造部材１０に固定具１９が固定された状態において、被覆部１２の第２平面１７の一部に対向するように配設される。この第２平面対向部２２には、後述する第２引張用接続材３４が貫通する複数の第２貫通孔２５が形成されている。各第２貫通孔２５は、第２引張用接続材３４の頭部を収容可能な座繰り付きの孔である。 The second plane facing portion 22 is a flat plate having the same width as the first plane facing portion 21 and shorter than the first plane facing portion 21, and is disposed so as to face a part of the second plane 17 of the covering portion 12 when the fastener 19 is fixed to the structural member 10. The second plane facing portion 22 has a plurality of second through holes 25 through which the second tension connecting members 34 described below pass. Each second through hole 25 is a countersunk hole capable of accommodating the head of the second tension connecting member 34.
折曲部２３は、被覆部１２の交差端１８の形状に倣うように折れ曲がっており、第１平面対向部２１の端部と第２平面対向部２２の端部とを接続している。以下では、第１平面対向部２１の端部および第２平面対向部２２の端部について、折曲部２３側の端部を基端部、折曲部２３の反対側の端部を先端部という。 The bent portion 23 is bent to follow the shape of the intersecting end 18 of the covering portion 12, and connects the end of the first plane opposing portion 21 with the end of the second plane opposing portion 22. Hereinafter, the end of the first plane opposing portion 21 and the end of the second plane opposing portion 22 on the side of the bent portion 23 will be referred to as the base end, and the end on the opposite side of the bent portion 23 will be referred to as the tip end.
固定部２０は、第１平面対向部２１の外表面２１ａに連結されている。固定部２０は、平板状をなしており、第１平面対向部２１の幅方向における中央部分から第１平面対向部２１の法線方向に沿って立設している。固定部２０は、第１平面対向部２１の法線方向において第１平面対向部２１に重なる第１固定部２７と、第２平面対向部２２の外表面２２ａよりも第１平面対向部２１の先端部の反対側へ突出する第２固定部２８と、を有している。第１平面対向部２１と固定部２０との連結部分２９の長さＬは、固定部２０の幅ｔよりも大きな値に設定される。 The fixing part 20 is connected to the outer surface 21a of the first plane opposing part 21. The fixing part 20 is flat and stands from the center of the first plane opposing part 21 in the width direction along the normal direction of the first plane opposing part 21. The fixing part 20 has a first fixing part 27 that overlaps the first plane opposing part 21 in the normal direction of the first plane opposing part 21, and a second fixing part 28 that protrudes beyond the outer surface 22a of the second plane opposing part 22 to the side opposite the tip of the first plane opposing part 21. The length L of the connecting part 29 between the first plane opposing part 21 and the fixing part 20 is set to a value greater than the width t of the fixing part 20.
（固定方法）
図４を参照して、構造部材１０に対する固定具１９の固定方法について説明する。
図４に示すように、固定部材１５は、固定具１９を構造部材１０に接続する接続部として、第１圧縮用接続材３１、第１引張用接続材３２、第２圧縮用接続材３３、および、第２引張用接続材３４を有している。
(Fixing method)
A method of fixing the fastener 19 to the structural member 10 will be described with reference to FIG.
As shown in FIG. 4 , the fixing member 15 has a first compression connecting member 31, a first tension connecting member 32, a second compression connecting member 33, and a second tension connecting member 34 as connection parts that connect the fixing device 19 to the structural member 10.
第１圧縮用接続材３１および第１引張用接続材３２は、固定具１９の第１平面対向部２１を構造部材１０の構造部１１に接続する第１接続部を構成する。第２圧縮用接続材３３および第２引張用接続材３４は、固定具１９の第２平面対向部２２を構造部材１０の構造部１１に接続する第２接続部を構成する。各接続材３１～３４は、例えば皿状の頭部を有しており、構造部材１０の構造部１１に対してねじ結合される。なお、各接続材３１～３４は、構造部１１の内部に配設される部分にねじ部を有していればよい。 The first compression connecting member 31 and the first tension connecting member 32 constitute a first connecting portion that connects the first planar opposing portion 21 of the fastener 19 to the structural portion 11 of the structural member 10. The second compression connecting member 33 and the second tension connecting member 34 constitute a second connecting portion that connects the second planar opposing portion 22 of the fastener 19 to the structural portion 11 of the structural member 10. Each connecting member 31-34 has, for example, a dish-shaped head, and is screwed to the structural portion 11 of the structural member 10. Note that each connecting member 31-34 only needs to have a threaded portion in the portion that is disposed inside the structural portion 11.
構造部材１０に対して固定具１９を固定する際には、まず、第１圧縮用接続材３１と第２圧縮用接続材３３とを構造部材１０の構造部１１に接続する。
第１圧縮用接続材３１は、被覆部１２の第１平面１６における所定の配置位置において、第１平面対向部２１の法線方向に沿うようにねじ込まれる。これにより、第１圧縮用接続材３１は、被覆部１２を貫通して構造部１１に接続される。第１圧縮用接続材３１の頭部と被覆部１２との間にはワッシャ３５が配設される。第１圧縮用接続材３１は、頭部と被覆部１２とによってワッシャ３６が挟持される位置までねじ込まれる。
When fixing the fastener 19 to the structural member 10 , first, the first compression connecting member 31 and the second compression connecting member 33 are connected to the structural portion 11 of the structural member 10 .
The first compression connecting material 31 is screwed in a predetermined position on the first plane 16 of the covering portion 12 along the normal direction of the first plane opposing portion 21. As a result, the first compression connecting material 31 penetrates the covering portion 12 and is connected to the structural portion 11. A washer 35 is disposed between the head of the first compression connecting material 31 and the covering portion 12. The first compression connecting material 31 is screwed in to a position where the washer 36 is sandwiched between the head and the covering portion 12.
第２圧縮用接続材３３は、被覆部１２の第２平面１７における所定の配置位置において、第２平面対向部２２の法線方向に沿うようにねじ込まれる。これにより、第２圧縮用接続材３３は、被覆部１２を貫通して構造部１１に接続される。第２圧縮用接続材３３の頭部と被覆部１２との間にはワッシャ３６が配設される。第２圧縮用接続材３３は、頭部と被覆部１２とによってワッシャ３６が挟持される位置までねじ込まれる。 The second compression connecting material 33 is screwed in a predetermined position on the second plane 17 of the covering portion 12 along the normal direction of the second plane opposing portion 22. As a result, the second compression connecting material 33 penetrates the covering portion 12 and is connected to the structural portion 11. A washer 36 is disposed between the head of the second compression connecting material 33 and the covering portion 12. The second compression connecting material 33 is screwed in to a position where the washer 36 is clamped between the head and the covering portion 12.
次に、固定具１９を所定位置に配置したうえで、第１引張用接続材３２と第２引張用接続材３４とを構造部材１０の構造部１１に接続する。
第１引張用接続材３２は、第１平面対向部２１に形成された第１貫通孔２４を通じて、第１平面対向部２１の法線方向に沿うように構造部材１０にねじ込まれる。第１引張用接続材３２は、第１貫通孔２４に設けられた座繰りに頭部が収容される位置までねじ込まれる。これにより、第１引張用接続材３２は、第１平面対向部２１および被覆部１２を貫通して構造部１１に接続される。第１引張用接続材３２は、被覆部１２から離間する方向への第１平面対向部２１の変位が抑えられるように、その頭部が、第１平面対向部２１を基準とした第１平面１６の反対側から第１平面対向部２１に係合している。
Next, with the fastener 19 placed in place, the first tension connector 32 and the second tension connector 34 are connected to the structural portion 11 of the structural member 10 .
The first tension connecting member 32 is screwed into the structural member 10 along the normal direction of the first plane opposing portion 21 through the first through hole 24 formed in the first plane opposing portion 21. The first tension connecting member 32 is screwed into a position where the head is accommodated in the counterbore provided in the first through hole 24. In this way, the first tension connecting member 32 is connected to the structural member 11 through the first plane opposing portion 21 and the covering portion 12. The head of the first tension connecting member 32 engages with the first plane opposing portion 21 from the opposite side of the first plane 16 based on the first plane opposing portion 21 so that the displacement of the first plane opposing portion 21 in the direction away from the covering portion 12 is suppressed.
第２引張用接続材３４は、第２平面対向部２２に形成された第２貫通孔２５を通じて、第２平面対向部２２の法線方向に沿うように構造部材１０にねじ込まれる。第２引張用接続材３４は、第２貫通孔２５に設けられた座繰りに頭部が収容される位置まで構造部材１０にねじ込まれる。これにより、第２引張用接続材３４は、第２平面対向部２２および被覆部１２を貫通して構造部１１に接続される。第２引張用接続材３４は、被覆部１２から離間する方向への第２平面対向部２２の変位が抑えられるように、その頭部が、第２平面対向部２２を基準とした第２平面１７の反対側から第２平面対向部２２に係合している。 The second tension connection member 34 is screwed into the structural member 10 along the normal direction of the second plane facing portion 22 through the second through hole 25 formed in the second plane facing portion 22. The second tension connection member 34 is screwed into the structural member 10 to a position where the head is accommodated in the counterbore provided in the second through hole 25. In this way, the second tension connection member 34 is connected to the structural member 11 through the second plane facing portion 22 and the covering portion 12. The head of the second tension connection member 34 engages with the second plane facing portion 22 from the opposite side of the second plane 17 based on the second plane facing portion 22 so that the displacement of the second plane facing portion 22 in the direction away from the covering portion 12 is suppressed.
このようにして構造部材１０に固定具１９が固定されると、固定具１９の第１平面対向部２１と被覆部１２の第１平面１６との間には、第１圧縮用接続材３１の頭部分の隙間３８が形成される。第１平面対向部２１は、被覆部１２側が第１圧縮用接続材３１によって支持され、被覆部１２の反対側が第１引張用接続材３２で支持される。また、固定具１９の第２平面対向部２２と被覆部１２の第２平面１７との間には、第２圧縮用接続材３３の頭部分の隙間３９が形成される。第２平面対向部２２は、被覆部１２側が第２圧縮用接続材３３によって支持され、被覆部１２の反対側が第２引張用接続材３４によって支持される。 When the fixing device 19 is fixed to the structural member 10 in this manner, a gap 38 for the head portion of the first compression connecting material 31 is formed between the first plane facing portion 21 of the fixing device 19 and the first plane 16 of the covering portion 12. The first plane facing portion 21 is supported on the covering portion 12 side by the first compression connecting material 31, and the opposite side of the covering portion 12 is supported by the first tension connecting material 32. In addition, a gap 39 for the head portion of the second compression connecting material 33 is formed between the second plane facing portion 22 of the fixing device 19 and the second plane 17 of the covering portion 12. The second plane facing portion 22 is supported on the covering portion 12 side by the second compression connecting material 33, and the opposite side of the covering portion 12 is supported by the second tension connecting material 34.
（各接続材の配置位置）
図５を参照して、第１圧縮用接続材３１および第１引張用接続材３２の配置位置の一例について説明する。図５においては、第１圧縮用接続材３１の配置位置を×印、第１引張用接続材３２の配置位置を○印にて示している。
(Position of each connecting member)
An example of the positions of the first compression connection material 31 and the first tension connection material 32 will be described with reference to Fig. 5. In Fig. 5, the position of the first compression connection material 31 is indicated by an x mark, and the position of the first tension connection material 32 is indicated by an o mark.
図５に示すように、第１圧縮用接続材３１および第１引張用接続材３２は、第１平面対向部２１の長さ方向に沿って並ぶように、また、幅方向に沿って並ぶように配置されている。 As shown in FIG. 5, the first compression connecting member 31 and the first tension connecting member 32 are arranged so as to be aligned along the length direction of the first planar opposing portion 21 and also along the width direction.
第１平面対向部２１の長さ方向における中央よりも折曲部２３側には、第１平面対向部２１の幅方向に沿って第１圧縮用接続材３１が並んで配置されている。具体的には、第１圧縮用接続材３１は、第１平面対向部２１の幅方向における中央と、その中央の両側と、に配置されている。中央に位置する第１圧縮用接続材３１は、第１平面対向部２１の法線方向において固定部２０に重なっている。中央の両側に位置する第１圧縮用接続材３１は、固定部２０の両側に配置されている。 The first compression connecting members 31 are arranged side by side along the width direction of the first plane opposing portion 21, closer to the bent portion 23 than the center in the length direction of the first plane opposing portion 21. Specifically, the first compression connecting members 31 are arranged at the center in the width direction of the first plane opposing portion 21 and on both sides of the center.

A second tensile force F22 that pulls the second plane opposing portion 22 away from the second plane 17 of the covering portion 12 along the normal direction of the second plane opposing portion 22
The sliding force is transmitted to the structural portion 11 of the structural member 10 via the first tension connecting member 32 at the first planar opposing portion 21 and via the second tension connecting member 34 at the second planar opposing portion 22 .
第１圧縮力Ｆ１１は、第１平面対向部２１においては第１圧縮用接続材３１を介して、第２平面対向部２２においては第２引張用接続材３４を介して、構造部材１０の構造部１１に伝達される。 The first compressive force F11 is transmitted to the structural part 11 of the structural member 10 via the first compression connecting member 31 at the first plane opposing part 21 and via the second tension connecting member 34 at the second plane opposing part 22.
第１引張力Ｆ１２は、第１平面対向部２１においては第１引張用接続材３２を介して、第２平面対向部２２においては第２引張用接続材３４を介して、構造部材１０の構造部１１に伝達される。 The first tensile force F12 is transmitted to the structural part 11 of the structural member 10 via the first tension connecting member 32 at the first plane opposing part 21 and via the second tension connecting member 34 at the second plane opposing part 22.
第２圧縮力Ｆ２１は、第１平面対向部２１においては第１引張用接続材３２を介して、第２平面対向部２２においては第２圧縮用接続材３３を介して、構造部材１０の構造部１１に伝達される。 The second compressive force F21 is transmitted to the structural part 11 of the structural member 10 via the first tension connecting member 32 at the first plane opposing part 21 and via the second compression connecting member 33 at the second plane opposing part 22.

本実施形態の効果について説明する。
（１）固定具１９に作用した外力を被覆部１２に伝達されにくくすることができる。
（２）第１圧縮用接続材３１の一部は、第１引張用接続材３２よりも折曲部２３に近い位置に配置されている。これにより、第１圧縮力Ｆ１１と第２引張力Ｆ２２とに基づくモーメントをその第１圧縮用接続材３１で効果的に受け止めることができる。
The effects of this embodiment will be described.
(1) An external force acting on the fixing device 19 can be made less likely to be transmitted to the covering portion 12 .
(2) A portion of the first compression connecting member 31 is disposed at a position closer to the bent portion 23 than the first tension connecting member 32. This allows the first compression connecting member 31 to effectively withstand the moment based on the first compressive force F11 and the second tension force F22.
（３）第１圧縮用接続材３１は、第１平面対向部２１の長さ方向における複数の位置に配置されている。これにより、第１圧縮力Ｆ１１と第２引張力Ｆ２２とに基づくモーメントを、より効果的に第１圧縮用接続材３１で受け止めることができる。 (3) The first compression connecting member 31 is arranged at multiple positions in the longitudinal direction of the first planar opposing portion 21. This allows the first compression connecting member 31 to more effectively receive the moment based on the first compressive force F11 and the second tensile force F22.
（４）第１圧縮用接続材３１の一部は、第１平面対向部２１の法線方向において固定部２０に重なる位置に配置されている。これにより、固定部２０から第１平面対向部２１に伝達された第１圧縮力Ｆ１１を効率よく構造部１１に伝達することができる。 (4) A portion of the first compression connecting member 31 is positioned so as to overlap the fixed portion 20 in the normal direction of the first plane opposing portion 21. This allows the first compression force F11 transmitted from the fixed portion 20 to the first plane opposing portion 21 to be efficiently transmitted to the structural portion 11.
（５）第１引張用接続材３２の一部は、第１圧縮用接続材３１よりも折曲部２３に遠い位置に配置されている。これにより、第１引張力Ｆ１２と第２圧縮力Ｆ２１とに基づくモーメントに起因した固定具１９の変位を効果的に抑えることができる。 (5) A portion of the first tension connecting member 32 is positioned farther from the bent portion 23 than the first compression connecting member 31. This effectively reduces the displacement of the fastener 19 caused by the moment based on the first tension force F12 and the second compression force F21.
（６）第１圧縮用接続材３１および第１引張用接続材３２は、第１平面対向部２１の幅方向における中央の両側に配置されている。これにより、幅方向における一方側を第１平面１６に押し付けるとともに他方側を第１平面１６から引き離すようなモーメントが第１平面対向部２１に作用したとしても、そのモーメントに基づく力を効率よく構造部１１に伝達することができる。 (6) The first compression connecting member 31 and the first tension connecting member 32 are arranged on both sides of the center in the width direction of the first plane opposing portion 21. As a result, even if a moment acts on the first plane opposing portion 21 such that one side in the width direction is pressed against the first plane 16 and the other side is pulled away from the first plane 16, the force based on the moment can be efficiently transmitted to the structural portion 11.
（７）第２圧縮用接続材３３は、第２引張用接続材３４よりも折曲部２３に近い位置に配置される。これにより、第１引張力Ｆ１２と第２圧縮力Ｆ２１とに基づくモーメントを第２圧縮用接続材３３で効果的に受け止めることができる。 (7) The second compression connecting member 33 is positioned closer to the bent portion 23 than the second tension connecting member 34. This allows the second compression connecting member 33 to effectively withstand the moment based on the first tension force F12 and the second compression force F21.
（８）第２引張用接続材３４は、第２圧縮用接続材３３よりも折曲部２３に遠い位置に配置される。これにより、第１圧縮力Ｆ１１と第２引張力Ｆ２２とに基づくモーメントに起因した固定具１９の変位を効果的に抑えることができる。 (8) The second tension connecting member 34 is positioned farther from the bent portion 23 than the second compression connecting member 33. This effectively reduces the displacement of the fastener 19 caused by the moment based on the first compression force F11 and the second tension force F22.
（９）第２圧縮用接続材３３および第２引張用接続材３４は、第２平面対向部２２の幅方向における中央の両側に配置される。これにより、幅方向における一方側を第２平面１７に押し付けるとともに他方側を第２平面１７から引き離すようなモーメントが第２平面対向部２２に作用したとしても、そのモーメントに基づく力を効率よく構造部１１に伝達することができる。 (9) The second compression connecting member 33 and the second tension connecting member 34 are arranged on both sides of the center in the width direction of the second plane opposing portion 22. As a result, even if a moment acts on the second plane opposing portion 22 such that one side in the width direction is pressed against the second plane 17 and the other side is pulled away from the second plane 17, the force based on the moment can be efficiently transmitted to the structural portion 11.
（１０）被覆部１２の第１平面１６と固定具１９の第１平面対向部２１との間には、第１圧縮用接続材３１によって隙間３８が形成されている。これにより、第１平面対向部２１から第１平面１６への直接的な力の伝達が回避される。 (10) A gap 38 is formed between the first plane 16 of the covering portion 12 and the first plane facing portion 21 of the fixing device 19 by the first compression connecting material 31. This prevents a direct force from being transmitted from the first plane facing portion 21 to the first plane 16.
（１１）被覆部１２の第２平面１７と固定具１９の第２平面対向部２２との間には、第２圧縮用接続材３３によって隙間３９が形成されている。これにより、第２平面対向部２２から第２平面１７への直接的な力の伝達が回避される。 (11) A gap 39 is formed between the second plane 17 of the covering portion 12 and the second plane facing portion 22 of the fixing device 19 by the second compression connecting material 33. This prevents direct force transmission from the second plane facing portion 22 to the second plane 17.
（１２）固定部２０は、第１固定部２７と第２固定部２８とを有している。これにより、固定部２０に対する外部取付部材１３の固定位置の自由度を向上させることができる。
（１３）連結部分２９の長さＬが固定部２０の幅ｔよりも大きな値に設定されている。これにより、第１平面対向部２１に対して固定部２０をより強固に連結することができる。
(12) The fixing portion 20 has the first fixing portion 27 and the second fixing portion 28. This improves the degree of freedom in the fixing position of the external mounting member 13 relative to the fixing portion 20.
(13) The length L of the connecting portion 29 is set to a value greater than the width t of the fixed portion 20. This makes it possible to connect the fixed portion 20 to the first plane facing portion 21 more firmly.
本実施形態は、以下のように変更して実施することができる。本実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。
・第１平面１６と第２平面１７とは、交差する面であればよく、互いに直交する面に限られない。

・第１圧縮用接続材３１は、第１引張用接続材３２よりも第１平面対向部２１の先端部側に位置していてもよい。
The first plane 16 is not limited to a horizontal plane, but may be a vertical plane. This allows the fastener 19 to be fixed to the structural member 10 having a vertical plane.
The first compression connecting member 31 may be located closer to the tip end of the first plane opposing portion 21 than the first tension connecting member 32 .
・第２圧縮用接続材３３は、第２引張用接続材３４よりも第２平面対向部２２の先端部側に位置していてもよい。

The fixing portion 20 may be provided on both the first plane facing portion 21 and the second plane facing portion 22 .
The external mounting member 13 is not limited to an exterior material such as a curtain wall, but may be a signboard, an air outlet unit of an air conditioning system, or the like.
・被覆部１２は、構造部１１を被覆しているものであればよく、石膏材などで形成される層や化粧板などで形成される層など、複数の層で構成されていてもよい。
・固定具１９の固定部２０は、図８に示すような形状であってもよい。なお、図８においては、上記実施形態と異なる部分について詳細に説明し、上記実施形態と同様の部分については同様の符号を付すことによりその詳細な説明は省略する。
The covering portion 12 may be any portion that covers the structural portion 11, and may be composed of multiple layers, such as a layer formed of a plaster material or the like and a layer formed of a decorative panel or the like.
The fixing portion 20 of the fixing device 19 may have a shape as shown in Fig. 8. In Fig. 8, parts that are different from the above embodiment will be described in detail, and parts that are the same as those in the above embodiment will be denoted by the same reference numerals and detailed description thereof will be omitted.
図８に示すように、固定部２０は、第１平面対向部２１に連結された一対の脚部４１と、一対の脚部４１に連結された頂面部４２と、を有している。
各脚部４１は、平板状をなしており、第１平面対向部２１の法線方向に沿って立設するように第１平面対向部２１の外表面２１ａに連結されている。一対の脚部４１は、第１平面対向部２１の幅方向において対向するように設けられている。頂面部４２は、平板状をなしており、一対の脚部４１の頂端部に連結されている。頂面部４２は、一対の脚部４１の間に位置する中間部分と、第１平面対向部２１の幅方向において一対の脚部４１から突出する突出部分とを有している。
As shown in FIG. 8 , the fixed portion 20 has a pair of legs 41 connected to the first flat surface opposing portion 21 , and a top surface portion 42 connected to the pair of legs 41 .
Each leg 41 has a flat plate shape and is connected to the outer surface 21a of the first plane opposing portion 21 so as to stand along the normal direction of the first plane opposing portion 21. The pair of legs 41 are provided to face each other in the width direction of the first plane opposing portion 21. The top surface portion 42 has a flat plate shape and is connected to the top ends of the pair of legs 41. The top surface portion 42 has an intermediate portion located between the pair of legs 41 and a protruding portion that protrudes from the pair of legs 41 in the width direction of the first plane opposing portion 21.
この固定部２０において、外部取付部材１３は、頂面部４２に固定される。外部取付部材１３は、中間部分に固定されてもよいし、突出部分に固定されてもよいし、中間部分および突出部分の双方に対して固定されていてもよい。また、第１圧縮用接続材３１は第１平面対向部２１の法線方向において各脚部４１に重なる位置に配置されることが好ましく、第１引張用接続材３２は一対の脚部４１の両側に配置されることが好ましい。 In this fixing portion 20, the external attachment member 13 is fixed to the top surface portion 42. The external attachment member 13 may be fixed to the middle portion, the protruding portion, or both the middle portion and the protruding portion. In addition, the first compression connecting member 31 is preferably positioned so as to overlap each leg portion 41 in the normal direction of the first flat surface opposing portion 21, and the first tension connecting member 32 is preferably positioned on both sides of the pair of legs 41.
こうした構成によれば、固定部２０そのものの機械的強度を高めることができるとともに、第１平面対向部２１に対し、より強固に固定部２０を連結することができる。また、頂面部４２に作用する外力は、一対の脚部４１によって分散されたうえで第１平面対向部２１に伝達される。このため、その外力に起因した接続材３１，３２の負荷、ひいては構造部１１における接続材３１，３２の結合部分の負荷を小さくすることができる。 This configuration increases the mechanical strength of the fixing portion 20 itself, and allows the fixing portion 20 to be more firmly connected to the first plane opposing portion 21. Furthermore, an external force acting on the top surface portion 42 is dispersed by the pair of legs 41 and then transmitted to the first plane opposing portion 21. This reduces the load on the connecting members 31, 32 caused by the external force, and ultimately the load on the joint portion of the connecting members 31, 32 in the structural portion 11.
・固定部２０は、第１平面対向部２１と外部取付部材１３との相対位置、固定部２０に作用する荷重などに応じて形状変更可能である。
例えば、図８に示す固定部２０は、脚部４１を介して第１平面対向部２１に頂面部４２が連結されていればよい。脚部４１は、１つであってもよいし、３つ以上であってもよい。また、脚部４１は、第１平面対向部２１の幅方向に連結部分２９が延在する構成であってもよい。頂面部４２は、第１平面対向部２１の法線方向から見たときに、全てが第１平面対向部２１に重なる形状であってもよいし、一部が第１平面対向部２１の外側に位置する形状であってもよい。
The shape of the fixing portion 20 can be changed depending on the relative position between the first plane opposing portion 21 and the external mounting member 13, the load acting on the fixing portion 20, and the like.
For example, the fixing portion 20 shown in Fig. 8 may have a top surface portion 42 connected to the first plane opposing portion 21 via a leg portion 41. The number of leg portions 41 may be one, or three or more. The leg portions 41 may also be configured such that a connecting portion 29 extends in the width direction of the first plane opposing portion 21. The top surface portion 42 may be shaped so that the entire top surface portion 42 overlaps the first plane opposing portion 21 when viewed from the normal direction of the first plane opposing portion 21, or may be shaped so that a portion of the top surface portion 42 is located outside the first plane opposing portion 21.
