Description
この発明は、斜材によって水平荷重に対する補強が行われた耐力壁に関する。 This invention relates to a shear wall reinforced against horizontal loads using diagonal members.
耐力壁として、斜材にターンバックルブレースを用いた構造やフラットバーを用いた構造が知られている。また、特許文献１には、斜材に角形鋼管を用いた耐力壁が開示されている。 Known shear walls include structures that use turnbuckle braces as diagonal members and structures that use flat bars. Patent Document 1 also discloses a shear wall that uses square steel pipes as diagonal members.
しかしながら、上記ターンバックルブレースを用いた耐力壁では、ブレースを緊張するターンバックルが必要なために割高になる。一方、上記フラットバーを用いた耐力壁では、ターンバックルを利用できないため、フラットバーを緊張することができない。このため、フラットバーに対して初期張力を導入できず、また、製造精度および施工精度に起因してフラットバーが撓むこともあり、耐力壁の初期剛性が低いという欠点もある。斜材が角形鋼管である構造でも同様の問題点がある。 However, shear walls using the above-mentioned turnbuckle braces are expensive because they require turnbuckles to tension the braces. On the other hand, shear walls using the above-mentioned flat bars cannot use turnbuckles, so the flat bars cannot be tensioned. This means that initial tension cannot be applied to the flat bars, and the flat bars can bend due to manufacturing and construction inaccuracies, resulting in low initial rigidity for the shear wall. Similar problems exist in structures where the diagonal members are square steel pipes.
この発明は、斜材がフラットバー等であってもその緊張が可能である耐力壁を提供することを目的とする。 The purpose of this invention is to provide a shear wall that can tension diagonal members even if they are flat bars, etc.
この発明の耐力壁は、斜材の両端に設けられた装着部が建物の躯体に固定された接続部材に連結される耐力壁であって、
上記斜材の一方側の装着部は、当該斜材の中心線方向に挿通孔を有しており、
上記一方側の装着部と上記接続部材とが上記中心線方向に離間しており、
上記一方側の装着部と上記接続部材のいずれか一方の側に設けられて上記挿通孔に通された雄螺子部と、他方の側の雌螺子部とが螺合しており、
上記雄螺子部と上記雌螺子部の上記螺合によるいずれか一方の移動によって上記一方側の装着部が上記接続部材側に引っ張られていることを特徴とする。
The shear wall of this invention is a shear wall in which the attachment parts provided at both ends of the diagonal members are connected to connecting members fixed to the skeleton of the building,
The mounting portion on one side of the diagonal member has an insertion hole in the center line direction of the diagonal member,
the mounting portion on one side and the connecting member are spaced apart in the center line direction,
a male screw portion provided on either the mounting portion on one side or the connecting member and passed through the insertion hole is screwed into a female screw portion on the other side,
The mounting portion on one side is pulled toward the connecting member by movement of either the male screw portion or the female screw portion due to the screw engagement.
上記の構成であれば、上記雄螺子部と上記雌螺子部の上記螺合によるいずれか一方の移動によって上記一方側の装着部が上記接続部材側に引っ張られるので、上記斜材としてフラットバーや角形鋼管等を用いる構造でも、このフラットバーを緊張することができる。 With the above configuration, the movement of either the male or female threaded portion due to the threaded engagement pulls the mounting portion on one side toward the connecting member, so even in structures that use flat bars or square steel pipes as the diagonal members, the flat bars can be tensioned.
上記一方側の装着部は、上記斜材の端面から離間して位置するプレート部を有しており、このプレート部に上記挿通孔を有してもよい。これによれば、上記雄螺子部或いは上記雌螺子部を、上記離間の箇所において上記一方側の装着部に設けることができる。 The mounting portion on one side may have a plate portion located away from the end face of the diagonal member, and this plate portion may have the insertion hole. In this way, the male screw portion or the female screw portion can be provided on the mounting portion on one side at the separated location.
上記一方側の反対側に位置する他方側の装着部は、上記接続部材に、当該耐力壁の壁面に直交する方向にねじ込まれたボルトによって固定されてもよい。これによれば、上記他方側の装着部については、上記ボルトのせん断耐力を用いた簡易な接続となり、耐力壁の現場製作の作業性が向上する。 The other mounting portion, located on the opposite side of the one side, may be fixed to the connecting member with a bolt threaded perpendicular to the wall surface of the bearing wall. This allows for a simple connection using the shear strength of the bolt, improving the workability of on-site construction of the bearing wall.
上記一方側の装着部が連結される接続部材が上記雌螺子部を備えており、上記一方側の装着部に設けられる上記雄螺子部である頭付きボルトが上記挿通孔に挿通されて上記雌螺子部に螺合されてもよい。 The connecting member to which the one mounting portion is connected may include the female thread portion, and the headed bolt, which is the male thread portion provided on the one mounting portion, may be inserted into the insertion hole and screwed into the female thread portion.
或いは、上記一方側の装着部が連結される接続部材が上記雄螺子部を備えており、上記一方側の装着部に設けられる上記雌螺子部であるナットが上記挿通孔に挿通された上記雄螺子部に螺合されてもよい。 Alternatively, the connecting member to which the one mounting portion is connected may include the male thread portion, and the nut, which is the female thread portion provided on the one mounting portion, may be threaded onto the male thread portion inserted into the insertion hole.
上記耐力壁において、上記一方側の装着部における上記斜材の中心線を中心とする回転が、当該装着部に備えられた係止部が上記接続部材に係止されることで阻止されてもよい。これによれば、上記雄螺子部と上記雌螺子部との螺合で上記斜材が緊張される際に当該斜材に捩じれが生じるのを防止できる。 In the above-mentioned bearing wall, rotation of the diagonal member around the center line of the mounting portion on one side may be prevented by engaging a locking portion provided on the mounting portion with the connecting member. This prevents twisting of the diagonal member when the diagonal member is tensioned by threading the male screw portion into the female screw portion.
上記係止部は、上記雄螺子部および上記雌螺子部よりも上記躯体としての柱の側に位置してもよい。これによれば、上記柱が位置していない側から上記雄螺子部等の配置や操作が行えるので、耐力壁製作の作業性が向上する。 The locking portion may be located closer to the column (the main body) than the male and female threads. This allows the male threads to be positioned and operated from the side where the column is not located, improving the workability of the shear wall construction.
本発明であれば、斜材としてフラットバー等を用いる構造でも、その緊張が可能であり、当該斜材において初期張力を導入することができ、また、製造精度および施工精度による斜材の撓みを解消して、耐力壁の初期剛性を高めることができるという効果を奏する。 The present invention makes it possible to tension structures that use flat bars or other diagonal members, allowing for the introduction of initial tension in the diagonal members. It also eliminates deflection of the diagonal members due to manufacturing and construction inaccuracies, thereby increasing the initial rigidity of the shear wall.
（実施形態１）
以下、この発明の一態様に係る実施形態を添付図面に基づいて説明する。
図１に示すように、この実施形態の耐力壁１は、斜材であるフラットバー２をクロス状に備えている。各フラットバー２の上端側に位置する板状の装着部２１は、建物の躯体である柱１００の上部側に位置する上側接続部材３に連結されている。同様に、各フラットバー２の下端側に位置する緊張用の装着部２２は、上記柱１００の下部側に位置する下側接続部材４に連結されている。また、耐力壁１は、このような内部構造の外面側に、桟木、合板、石こうボード等を備えている。
(Embodiment 1)
Hereinafter, an embodiment according to one aspect of the present invention will be described with reference to the accompanying drawings.
As shown in Figure 1, the bearing wall 1 of this embodiment is equipped with a cross of flat bars 2, which are diagonal members. Plate-shaped mounting portions 21 located on the upper ends of each flat bar 2 are connected to upper connecting members 3 located on the upper side of columns 100, which form the skeleton of the building. Similarly, tensioning mounting portions 22 located on the lower ends of each flat bar 2 are connected to lower connecting members 4 located on the lower side of the columns 100. The bearing wall 1 also includes battens, plywood, gypsum board, etc. on the outer surface of this internal structure.
上記フラットバー２の装着部２１には、当該耐力壁１の壁面に直交する方向に貫通孔が形成されており、上側接続部材３にも、当該耐力壁１の壁面に直交する方向に貫通孔が形成されている。上記貫通孔にボルト・ナット３１のボルトが挿通され、当該ボルトにナットが締め付けられることで、上記装着部２１が上側接続部材３に固定される。すなわち、上記フラットバー２の上部側は、上記ボルトのせん断耐力によって上側接続部材３に固定される。なお、上記ボルト・ナット３１のナットは上側接続部材３に溶接等により固定されていてもよい。 A through-hole is formed in the mounting portion 21 of the flat bar 2 in a direction perpendicular to the wall surface of the bearing wall 1, and a through-hole is also formed in the upper connecting member 3 in a direction perpendicular to the wall surface of the bearing wall 1. The bolts of the bolt/nut 31 are inserted into the through-holes and the nuts are tightened onto the bolts, thereby fixing the mounting portion 21 to the upper connecting member 3. In other words, the upper side of the flat bar 2 is fixed to the upper connecting member 3 by the shear strength of the bolts. The nuts of the bolt/nut 31 may also be fixed to the upper connecting member 3 by welding or other means.
一方、上記フラットバー２の上記緊張用の装着部２２は、例えば、図２にも示すように、当該フラットバー２の狭幅の側面に一端側が溶接等により固定されたフランジ２２ａと、これらフランジ２２ａの他端側に溶接等により固定されたエンドプレート部２２ｂとを備える。上記エンドプレート部２２ｂは、フラットバー２の小口（端面）から離間して位置しており、この離間の箇所において後述する雄螺子部５を設けることができる。また、上記エンドプレート部２２ｂには、上記フラットバー２の中心線方向に挿通孔２２ｃが形成されている。 On the other hand, as shown in Figure 2, the tensioning attachment portion 22 of the flat bar 2 comprises a flange 22a, one end of which is fixed to the narrow side of the flat bar 2 by welding or the like, and an end plate portion 22b, the other end of which is fixed to the flange 22a by welding or the like. The end plate portion 22b is located away from the small end (end face) of the flat bar 2, and a male thread portion 5 (described below) can be provided at this space. An insertion hole 22c, described below, is also formed in the end plate portion 22b in the centerline direction of the flat bar 2.
図３（Ａ）および図３（Ｂ）に示すように、下側接続部材４の取付板部４１は、隣り合う柱１００，１００の対向面側に溶接等により固定されている。上記取付板部４１には、耐力壁１の壁厚方向に離間して位置する２枚の支持板４２が溶接等によって固定されている。そして、上記２枚の支持板４２の上端部には、上記エンドプレート部２２ｂに対向する連結プレート部４３が溶接等によって固定されている。上記連結プレート部４３には、上記フラットバー２の中心線方向に雌螺子部４３ａが切られている。上記装着部２２のエンドプレート部２２ｂと下側接続部材４の連結プレート部４３とは、上記フラットバー２の中心線方向に、設計上、例えば１０ｍｍ程度離間する。 As shown in Figures 3(A) and 3(B), the mounting plate portion 41 of the lower connecting member 4 is fixed to the opposing surfaces of adjacent columns 100, 100 by welding or other means. Two support plates 42, spaced apart in the wall thickness direction of the bearing wall 1, are fixed to the mounting plate portion 41 by welding or other means. A connecting plate portion 43, facing the end plate portion 22b, is fixed to the upper ends of the two support plates 42 by welding or other means. A female thread portion 43a is threaded in the center line direction of the flat bar 2 in the connecting plate portion 43. The end plate portion 22b of the mounting portion 22 and the connecting plate portion 43 of the lower connecting member 4 are designed to be spaced apart, for example, by approximately 10 mm in the center line direction of the flat bar 2.
上記挿通孔２２ｃには、上記エンドプレート部２２ｂと上記フラットバー２の小口との上記離間の箇所から雄螺子部５が挿通される。この実施形態では、上記雄螺子部５として頭付きボルトが用いられる。すなわち、上記緊張用の装着部２２に設けられる雄螺子部５である頭付きボルトが、上記挿通孔２２ｃに挿通されて、下側接続部材４の雌螺子部４３ａに螺合される。また、上記挿通孔２２ｃから突き出た雄螺子部５の螺子部に対して、例えばスプリングワッシャーを介在させた状態で緩み止め用のナット６が螺合される。 A male screw 5 is inserted into the insertion hole 22c from the gap between the end plate portion 22b and the end of the flat bar 2. In this embodiment, a headed bolt is used as the male screw 5. That is, the headed bolt, which is the male screw 5 provided on the tensioning attachment portion 22, is inserted into the insertion hole 22c and threaded into the female screw portion 43a of the lower connecting member 4. Furthermore, a locking nut 6 is threaded onto the threaded portion of the male screw 5 protruding from the insertion hole 22c, with a spring washer, for example, interposed therebetween.
上記雄螺子部（頭付きボルト）５を、雌螺子部４３ａに螺合させてねじ込んでいくと、雄螺子部５の頭部が下側に移動し、上記エンドプレート部２２ｂが上記連結プレート部４３側に引き寄せられる。すなわち、上記フラットバー２の装着部２２は、雌螺子部４３ａと雄螺子部５との螺合によって、下側接続部材４に連結されるとともに、上記雄螺子部５のねじ込みによる頭部の位置変位によって、下側接続部材４側に引っ張られる。 When the male screw portion (headed bolt) 5 is threaded into the female screw portion 43a, the head of the male screw portion 5 moves downward, and the end plate portion 22b is pulled toward the connecting plate portion 43. In other words, the mounting portion 22 of the flat bar 2 is connected to the lower connecting member 4 by the threaded engagement between the female screw portion 43a and the male screw portion 5, and is pulled toward the lower connecting member 4 by the positional displacement of the head due to the threading of the male screw portion 5.
上記フラットバー２において所定の緊張を生じさせた状態でも、図３（Ｂ）に示されるように、上記装着部２２のエンドプレート部２２ｂと上記連結プレート部４３との離間状態は維持される。上記の所定の緊張を生じさせた状態で、上記ナット６が上記エンドプレート部２２ｂ側に締め付けられて、上記雄螺子部５が緩み止め固定される。 Even when the flat bar 2 is tensioned, the end plate portion 22b of the mounting portion 22 and the connecting plate portion 43 remain separated, as shown in Figure 3(B). With the tension applied, the nut 6 is tightened against the end plate portion 22b, preventing the male thread portion 5 from loosening.
上記の構成であれば、上記雌螺子部４３ａに螺合する上記雄螺子部５のねじ込みによる当該雄螺子部５の頭部の移動によって、上記一方側の装着部２２が下側接続部材４側に引っ張られるので、上記斜材としてフラットバー２を用いる構造でも、このフラットバー２を緊張することができる。そして、このフラットバー２を用いる構造であれば、２枚のフラットバー２の交差部分の厚さは２本の丸鋼ブレースの交差部分の厚さよりも薄くでき、また、上記接続部材３，４の上記柱１００の中心に対する偏心が小さくなる或いは無くせるため、丸鋼ブレースを用いる構成に比べて、耐力壁１を薄くすることが可能になる。 With the above configuration, the head of the male screw portion 5, which threads into the female screw portion 43a, moves, pulling the mounting portion 22 on one side toward the lower connecting member 4. This allows the flat bar 2 to be tensioned even in a structure that uses a flat bar 2 as the diagonal member. Furthermore, with a structure that uses this flat bar 2, the thickness of the intersection of the two flat bars 2 can be made thinner than the thickness of the intersection of the two round steel braces. Furthermore, since the eccentricity of the connecting members 3 and 4 relative to the center of the column 100 can be reduced or eliminated, the shear wall 1 can be made thinner than in a structure that uses round steel braces.
また、上記装着部２１は、上側接続部材３に上記ボルト・ナット３１によって固定されるので、この他方側の装着部２１については、上記ボルトのせん断耐力を用いた簡易な接続となり、耐力壁１の現場製作の作業性が向上する。 In addition, since the mounting portion 21 is fixed to the upper connecting member 3 with the bolt and nut 31, the other mounting portion 21 is simply connected using the shear strength of the bolt, improving the workability of on-site construction of the bearing wall 1.
なお、図３（Ａ）では、便宜上、部材の位置関係を示し易くするため、上記装着部２２を下側接続部材４から大きく離間させて示している。耐力壁１の作製においては、例えば、先に上記フラットバー２の他方側の装着部２１を上側接続部材３にボルト・ナット３１で接続する。この接続状態において、一方側の装着部２２は連結プレート部４３から離間して位置し、この離間の状態で装着部２２側に設けた雄螺子部（頭付きボルト）５を、雌螺子部４３ａに螺合させてねじ込む作業が行える。また、上記装着部２２と連結プレート部４３とが離間していると、上記フラットバー２の緊張のためだけでなく、耐力壁１の製造や施工誤差等による装着部２２と連結プレート部４３との位置関係の誤差を吸収できる利点もある。 In Figure 3(A), for convenience, the mounting portion 22 is shown spaced far away from the lower connecting member 4 to make it easier to show the relative positions of the components. When constructing the bearing wall 1, for example, the mounting portion 21 on the other side of the flat bar 2 is first connected to the upper connecting member 3 with a bolt and nut 31. In this connected state, the mounting portion 22 on one side is positioned spaced apart from the connecting plate 43, and in this spaced position, the male threaded portion (headed bolt) 5 provided on the mounting portion 22 can be threaded into the female threaded portion 43a. Furthermore, having the mounting portion 22 spaced apart from the connecting plate 43 not only contributes to tensioning the flat bar 2, but also has the advantage of absorbing errors in the positional relationship between the mounting portion 22 and the connecting plate 43 due to manufacturing or construction errors in the bearing wall 1.
（実施形態２）
次に、実施形態２について説明する。この実施形態２では、実施形態１と共通の構成要素には同一の符号を付記してその説明を省略する。この実施形態２の耐力壁１において、上記フラットバー２自体の構造は、実施形態１と同じである。
(Embodiment 2)
Next, a second embodiment will be described. In this second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and their description will be omitted. In the shear wall 1 of this second embodiment, the structure of the flat bar 2 itself is the same as that of the first embodiment.
この実施形態２の耐力壁１は、図４（Ａ）および図４（Ｂ）に示すように、下側接続部材４Ａを備えている。下側接続部材４Ａは、上記フラットバー２の中心線上に高ナット４４を備えている。この高ナット４４は、図５にも示すように、螺子孔中心を１枚の支持板４２の板厚の中心に位置させており、溶接等によって当該支持板４２に固定されている。そして、上記高ナット４４には、例えば、雄螺子部５Ａとして植え込みボルトが螺合されている。雄螺子部５Ａの上部は、上記フラットバー２の挿通孔２２ｃに下側から挿通されてエンドプレート部２２ｂの上側に突出する。上記エンドプレート部２２ｂと上記フラットバー２の小口との離間の箇所に入れられた皿ばね付きナットである雌螺子部７が雄螺子部５Ａに螺合される。 As shown in Figures 4(A) and 4(B), the bearing wall 1 of this second embodiment includes a lower connecting member 4A. The lower connecting member 4A includes a high nut 44 on the centerline of the flat bar 2. As also shown in Figure 5, the screw hole center of this high nut 44 is positioned at the center of the plate thickness of one support plate 42, and it is fixed to the support plate 42 by welding or the like. A stud bolt, for example, is threaded into the high nut 44 as a male thread 5A. The upper part of the male thread 5A is inserted from below into the insertion hole 22c of the flat bar 2 and protrudes above the end plate 22b. A female thread 7, which is a nut with a disc spring inserted in the space between the end plate 22b and the small end of the flat bar 2, is threaded into the male thread 5A.
上記フラットバー２の装着部２２は、上記のように、雌螺子部７と雄螺子部５Ａとの螺合によって、下側接続部材４Ａに連結される。そして、雌螺子部７のねじ込みによる当該雌螺子部７の位置変位によって、上記フラットバー２の装着部２２が下側接続部材４Ａ側に引っ張られる。上記フラットバー２の所定の緊張状態は、上記ナット６が上記エンドプレート部２２ｂ側に締め付けられて保持される。 As described above, the mounting portion 22 of the flat bar 2 is connected to the lower connecting member 4A by threading the female thread portion 7 into the male thread portion 5A. The mounting portion 22 of the flat bar 2 is pulled toward the lower connecting member 4A as the female thread portion 7 is displaced by screwing it in. The flat bar 2 is maintained in a predetermined tensioned state by tightening the nut 6 against the end plate portion 22b.
上記の構成であれば、上記雄螺子部５Ａに螺合する上記雌螺子部７のねじ込みによる当該雌螺子部７の移動によって、上記一方側の装着部２２が下側接続部材４側に引っ張られるので、上記斜材としてフラットバー２を用いる構造でも、このフラットバー２を緊張することができる。 With the above configuration, the female screw portion 7, which threads into the male screw portion 5A, moves, pulling the mounting portion 22 on one side toward the lower connecting member 4. Therefore, even in a structure that uses a flat bar 2 as the diagonal member, the flat bar 2 can be tensioned.
また、実施形態２の耐力壁１の現場施工においては、図４（Ａ）に示す状態からフラットバー２を下方に移動させ、上記装着部２２の挿通孔２２ｃに上記雄螺子部５Ａを差し込んで、上記フラットバー２を下側接続部材４Ａで仮受けすることができる。この仮受け状態で、上記フラットバー２の装着部２１を上側接続部材３にボルト・ナット３１で接続する操作が行えるので、耐力壁１の現場製作の施工性が向上する。なお、先に上記装着部２１を上側接続部材３に接続し、上記フラットバー２を撓ませて、上記雄螺子部５Ａを上記装着部２２の挿通孔２２ｃに差し込むことも可能である。 Furthermore, during on-site construction of the shear wall 1 of embodiment 2, the flat bar 2 can be moved downward from the state shown in Figure 4(A) and the male thread portion 5A inserted into the insertion hole 22c of the mounting portion 22, temporarily retaining the flat bar 2 with the lower connecting member 4A. In this temporarily retained state, the mounting portion 21 of the flat bar 2 can be connected to the upper connecting member 3 with bolts and nuts 31, improving the ease of on-site construction of the shear wall 1. It is also possible to first connect the mounting portion 21 to the upper connecting member 3, then bend the flat bar 2 and insert the male thread portion 5A into the insertion hole 22c of the mounting portion 22.
また、上記エンドプレート部２２ｂと上記フラットバー２の小口との離間の箇所に入れる雌螺子部７はナットであり、上記の頭付きボルトに比べて薄いので、上記の離間の箇所の離間距離は狭くてもよい。 Furthermore, the female screw portion 7 inserted into the gap between the end plate portion 22b and the end of the flat bar 2 is a nut, which is thinner than the headed bolt, so the gap distance can be narrow.
また、上記雄螺子部５Ａとしての植え込みボルトを高強度のボルトとし、上記雌螺子部７を高強度のナットとすることができる。このように高強度のボルト・ナットの組み合わせが可能であると、螺子潰れ等を防止できる。 Furthermore, the stud bolt serving as the male thread portion 5A can be a high-strength bolt, and the female thread portion 7 can be a high-strength nut. This combination of high-strength bolts and nuts can prevent thread stripping and other problems.
なお、上記の例では、下側接続部材４Ａに高ナット４４を取り付け、この高ナット４４に雄螺子部５Ａとして植え込みボルトを螺合したが、上記高ナット４４を設けずに、雄螺子部５Ａとして螺子を切った丸鋼等を下側接続部材４Ａに溶接してもよい。 In the above example, a high nut 44 is attached to the lower connecting member 4A, and the stud bolt is screwed into this high nut 44 as the male thread portion 5A. However, it is also possible to weld a threaded round steel bar or the like to the lower connecting member 4A as the male thread portion 5A without providing the high nut 44.
また、図６に示すように、上記装着部２２は、上記フラットバー２の中心線から離れた位置で、下側接続部材４に係止される係止部２２１を有してもよい。係止部２２１は、例えば、柱１００に近い側のフランジ２２ａの下部側をエンドプレート部２２ｂよりも下方に突出させた突出部と、この突出部の先端に位置し、図７に示すように、下側接続部材４Ａの支持板４２に係止されるスリット２２ｄとからなっている。このスリット２２ｄの幅は、下側接続部材４Ａの支持板４２の板厚よりも幾分広くされており、上記スリット２２ｄを支持板４２に嵌めることができる。すなわち、上記一方側の装着部２２における上記フラットバー２の中心線を中心とする回転が、当該装着部２２に備えられた係止部２２１が上側接続部材４に係止されることで阻止される。これにより、上記雄螺子部５Ａと上記雌螺子部７との螺合によって上記フラットバー２が緊張される際に当該フラットバー２に捩じれが生じるのを防止できる。 6, the mounting portion 22 may have a locking portion 221 that engages with the lower connecting member 4 at a position away from the center line of the flat bar 2. The locking portion 221 may, for example, consist of a protrusion extending downward from the end plate portion 22b on the lower side of the flange 22a closest to the column 100, and a slit 22d located at the tip of the protrusion and engaging with the support plate 42 of the lower connecting member 4A, as shown in FIG. 7. The width of the slit 22d is slightly wider than the thickness of the support plate 42 of the lower connecting member 4A, allowing the slit 22d to fit into the support plate 42. In other words, rotation of the mounting portion 22 on one side about the center line of the flat bar 2 is prevented by the locking portion 221 provided on the mounting portion 22 engaging with the upper connecting member 4. This prevents twisting of the flat bar 2 when the flat bar 2 is tensioned by the engagement of the male thread portion 5A and the female thread portion 7.
また、上記係止部２２１が上記雄螺子部５Ａおよび上記雌螺子部７よりも上記柱１００側に存在すると、上記柱１００が位置していない側から上記雄螺子部５Ａ、上記雌螺子部７、ナット６の配置や操作等が行えるので、耐力壁１の現場製作の施工性が向上する。 Furthermore, if the locking portion 221 is located closer to the column 100 than the male screw portion 5A and the female screw portion 7, the male screw portion 5A, the female screw portion 7, and the nut 6 can be positioned and operated from the side where the column 100 is not located, improving the ease of on-site construction of the shear wall 1.
上記スリット２２ｄの開口から奥端面までの長さ（高さ）は、上記フラットバー２において所定の緊張が得られた状態で、支持板４２の上端面との間に所定の隙間が形成される長さ（高さ）とされる。この隙間として所定の隙間が設計上規定されていて、現場施工において上記隙間範囲を管理すれば、上記フラットバー２の適切な緊張状態を得ることが容易になる。 The length (height) from the opening of the slit 22d to the rear end surface is set to a length (height) that will create a specified gap between the upper end surface of the support plate 42 and the flat bar 2 when the flat bar 2 is under a specified tension. This specified gap is specified by design, and by managing the gap range during on-site construction, it becomes easy to achieve the appropriate tension state for the flat bar 2.
なお、実施形態１の耐力壁１の装着部２２についても、下側接続部材４に係止される係止部２２１を備えることができる。この構成の場合は、例えば、下側接続部材４の連結プレート部４３の柱側の端面、或いは、取付板部４１の上端中央に、上記係止部２２１のスリット２２ｄが嵌る板状部が形成される。 The mounting portion 22 of the bearing wall 1 in embodiment 1 can also be provided with a locking portion 221 that locks to the lower connecting member 4. In this configuration, for example, a plate-like portion into which the slit 22d of the locking portion 221 fits is formed on the column-side end surface of the connecting plate portion 43 of the lower connecting member 4 or on the center of the upper end of the mounting plate portion 41.
また、斜材として、上記フラットバー２に代えて、図８に示すように、フラットバー本体部分を丸鋼２３とする構造のブレース２Ａを用いることができる。ブレース２Ａは、例えば、フランジ２２ａのブレース２Ａ側の端部に、螺子孔付きの接続プレート部２２ｆを備えており、上記螺子孔にブレース２Ａの端部の螺子部２３ａが螺合されている。そして、例えば、上記接続プレート部２２ｆを抜け出たブレース２Ａの端部にスプリングワッシャー等を介在させてナット６Ａが螺合されることで、ブレース２Ａが接続プレート部２２ｆに固定される。ブレース２Ａの他端には、例えば、フラットバー２の上側端と同様、溶接によって接続板が固定される。さらに、このようなブレース２Ａについても、上記係止部２２１を備えることができる。 In addition, instead of the flat bars 2 described above, braces 2A can be used as diagonal members, with the flat bar main body made of round steel bars 23, as shown in Figure 8. The brace 2A has a connecting plate portion 22f with a threaded hole at the end of the flange 22a facing the brace 2A, and the threaded portion 23a at the end of the brace 2A is threaded into the threaded hole. Then, for example, a nut 6A is threaded onto the end of the brace 2A extending past the connecting plate portion 22f, with a spring washer or the like interposed, thereby securing the brace 2A to the connecting plate portion 22f. A connecting plate is secured to the other end of the brace 2A by welding, for example, in the same way as the upper end of the flat bar 2. Furthermore, such braces 2A can also be provided with the locking portion 221 described above.
なお、中央側（交差部側）にフラットバー部が位置するように、当該フラットバー部の両端に丸鋼ブレースを備えた構造の斜材を用いることもできる。また、斜材として、角形鋼管を採用し、この角形鋼管の一方の端部に装着部２２を設け、この装着部２２を下側接続部材４に接続する構造等とすることもできる。また、角形鋼管の端部に挿通孔を有するプレートを溶接等により固定して当該プレートを装着部とし、上記角形鋼管の端側の側面を一部切り欠いて切欠き部を形成し、この切欠き部から雄螺子部５や雌螺子部７を上記挿通孔に通すようにしてもよい。 It is also possible to use diagonal members with round steel braces on both ends of the flat bar section so that the flat bar section is located in the center (at the intersection). Alternatively, square steel pipes can be used as diagonal members, with an attachment section 22 provided at one end of the square steel pipe and connected to the lower connecting member 4. Alternatively, a plate with a through hole can be fixed to the end of the square steel pipe by welding or other means to serve as the attachment section, and a notch can be formed by cutting out part of the side of the end of the square steel pipe, and the male screw section 5 and female screw section 7 can be passed through the through hole.
