In addition, the opening lower frame member 24 and each frame member arranged below it are structured. The face material is fixed with a drill screw 23 to constitute a waist wall 27. Further, a structural face material is fixed to the vertical frame member 22 for attaching the lintel support and the frame material (vertical frame material 2 a) on both outer sides thereof with a drill screw 23 to form a side wall 28.
ちなみに、 上記開口部 8内には支持柱が存在しないため、 かかる 開口部 8 を構成する開口部上枠材 18、 開口部下枠材 24及びまぐさ受 け取付け用縦枠材 22の 4辺は、 地震等により水平方向の応力が作用 した場合に、 それぞれ水平方向に変位することになる。 この水平方 向に変位する場合において、 垂壁 26、 腰壁 27及び側面壁 28が相互に 剛結合されている場合には、 各壁が耐カ壁として作用するところ、 開口部 8周辺の枠材の水平方向への変位は、 抑制されることになる しかしながら、 従来では、 垂壁 26、 腰壁 27及び側面壁 28間を互い に緩く結合することにより、 互いの壁同士で変位が及ばないように していた。 図 10、 図 11は、 かかる従来の垂壁 26、 腰壁 27及び側面壁 28にっき水平力が加わった場合の挙動を示している。 この図 10、 図 1 1に示すように、 負荷された水平力に対して側面壁 28が揺動するこ とになるが、 かかる側面壁 28は、 垂壁 26及び腰壁 27に対して緩く結 合されているため、 これらに対して水平力が伝達されることはなく なる。 換言すれば、 開口部 8周辺に負荷された水平力は、 ほぼ全て 側面壁 28で担い、 かかる側面壁 28の揺動を介して打ち消されること になる。  Incidentally, since there is no support column in the opening 8, the four sides of the opening upper frame member 18, the opening lower frame member 24, and the vertical frame member 22 for mounting the lintel are configured on the opening 8. When a horizontal stress is applied due to an earthquake, etc., each will be displaced horizontally. When the vertical wall 26, the waist wall 27, and the side wall 28 are rigidly connected to each other in this horizontal displacement, each wall acts as a resistance wall. However, in the past, the vertical wall 26, the waist wall 27, and the side wall 28 are loosely coupled to each other so that the displacement between the walls does not reach each other. It was like that. 10 and 11 show the behavior when a horizontal force is applied to the conventional hanging wall 26, waist wall 27, and side wall 28. FIG. As shown in FIGS. 10 and 11, the side wall 28 swings with respect to the applied horizontal force. The side wall 28 is loosely connected to the hanging wall 26 and the waist wall 27. As a result, no horizontal force is transmitted to them. In other words, almost all of the horizontal force applied to the periphery of the opening 8 is carried by the side wall 28 and is canceled through the swinging of the side wall 28.
なお、 従来においては、 さらに側面壁 （袖壁） の面材の目地部を 垂壁の合板の位置とずらす 「壁構造及び面材貼設方法」 が提案され ている （例えば、 特開 2000— 234406号公報参照。 ） 。 また、 「木造 住宅の計算方法及びこれを利用して建築木造住宅」 も提案されてい る （例えば、 特開 2001— 164645号公報参照。 ） 。 発明の開示 Conventionally, there has been proposed a “wall structure and a method of attaching a face material” in which the joint portion of the face material of the side wall (sleeve wall) is shifted from the position of the plywood of the hanging wall (for example, JP-A-2000-2000). (See publication No. 234406.) In addition, “a method for calculating a wooden house and a wooden house built using this method” has been proposed (see, for example, Japanese Patent Laid-Open No. 2001-164645). Disclosure of the invention
上述した図 10， 1 1に示す例において、 開口部 8両側に設けられた 側面壁 28は、 開口部 8 の上下に位置する垂壁 26並びに腰壁 27に対し て離間している状態にある。 このため各側面壁 28は、 地震等に基づ く水平方向の揺れに対して抵抗が小さくなる結果、 水平方向への変 形量が大きくなる。 さらに、 側面壁 28内においては、 図 1 1の矢印の ように下向きのべク トルで表される引抜き力、 上向きのべク トルで 表される圧縮力、 右向きの力、 左向きの力が交互かつ循環的に作用 する。  In the example shown in FIGS. 10 and 11 described above, the side walls 28 provided on both sides of the opening 8 are separated from the vertical wall 26 and the waist wall 27 positioned above and below the opening 8. . For this reason, each side wall 28 becomes less resistant to horizontal shaking caused by an earthquake or the like, and as a result, the amount of deformation in the horizontal direction becomes larger. In addition, in the side wall 28, the pulling force represented by the downward vector, the compressive force represented by the upward vector, the rightward force, and the leftward force are alternated as indicated by the arrows in FIG. And it works cyclically.
即ち、 これら各方向に作用する力は互いに作用、 反作用の関係に あり、 また相互に釣り合いがとれているため、 左右の揺れが大きい ほど引抜き力、 圧縮力が大きくなる。 特に、 引抜き力は、 図 1 1に示 す点線楕円 （口） におけるベク トル量の合計であるので、 この引抜 き力が大きくなるにつれて、 圧縮力も大.きくなる。 この引抜き力 （ 圧縮力） の増大に対抗するためには、 側面壁 28を取付ける縦枠材を 大型化する必要があるとともに、 縦枠材を基礎等に取付けるための ホールダウン金物をより堅牢にすべく、 これを大型化する必要があ り、 さらに、 ホールダウン金物をコンクリート基礎に固着するため のアンカーを太く構成することにより強度を高める必要がある。  In other words, the forces acting in these directions are in the relationship of action and reaction, and are balanced with each other. Therefore, the greater the left / right swing, the greater the pulling force and compression force. In particular, the pull-out force is the sum of the vector amounts in the dotted ellipse (mouth) shown in Fig. 11. Therefore, as the pull-out force increases, the compression force increases. To counter this increase in pulling force (compression force), it is necessary to increase the size of the vertical frame material to which the side wall 28 is attached, and to make the hole-down hardware for mounting the vertical frame material to the foundation more robust. Therefore, it is necessary to increase the size, and it is necessary to increase the strength by constructing a thick anchor for fixing the hole-down hardware to the concrete foundation.
しかしながら、 かかる引抜き力 （圧縮力） に対抗するためにホー ルダウン金物等をいきおい大きく した場合に、 開口部 8周辺の構造 自体の耐カを大きくすることができる反面、 スチールハウス全体か らみれば、 一部分のみに高強度の構造が設けられている状態となる 。 このため、 地震等に基づいて大きな水平力がスチールハウスに負 荷した場合に、 かかる高強度に補強された開口部周辺に応力が集中 し、 また他の構成部材に対しても大きな負荷が加わることになる。 かかる他の構成部材に関しても、 別途補強部材等で固定強化してい く と、 最終的にスチールハウス全体に亘つて補強部材を貼り巡らさ なければならなくなり、 製作コス トゃ労力の面において妥当性を欠 く原因ともなる。 However, when the hole-down hardware is greatly increased to counter this pulling force (compressive force), the resistance of the structure around the opening 8 itself can be increased, but from the perspective of the steel house as a whole. A high-strength structure is provided only in a part. For this reason, when a large horizontal force is loaded on a steel house due to an earthquake or the like, the stress concentrates around the opening reinforced with such high strength, and a large load is also applied to other components. It will be. These other structural members are also fixed and reinforced with separate reinforcing members. In the end, it will be necessary to apply reinforcement members throughout the entire steel house, and the production cost will be a cause of lack of validity in terms of labor.
図 12は、 開口部 8の両側に設けられる側面壁 28の剪断変形量に対 する剪断耐力の関係を示している。 この図 12に示すように、 開口部 8の上下に位置する垂壁 26並びに腰壁 27に対して、 側面壁 28を離間 させる構成とした場合には、 図中 pに示すように、 剪断変形量に応 じて徐々に剪断応力が徐々に大きくなつていく。 これに対して、 開 口部 8周辺の枠材にっきホールダウン金物等を用いて補強した場合 には、 図中 qに示すように初期剛性の向上を図ることができる一方 で、 破断応力が大きく増加してしまう。  FIG. 12 shows the relationship between the shear strength and the shear deformation amount of the side wall 28 provided on both sides of the opening 8. As shown in FIG. 12, when the side wall 28 is separated from the vertical wall 26 and the waist wall 27 positioned above and below the opening 8, as shown in FIG. The shear stress gradually increases according to the amount. On the other hand, when the frame material around the opening 8 is reinforced with a hole-down hardware, the initial rigidity can be improved as shown in q in the figure, while the breaking stress is large. It will increase.
このため、 開口部 8周辺の枠材にっき図中 rの挙動に示されるよ うに、 初期剛性を高水準に維持しつつ、 破断応力を低く抑えること によりスチールハウス中の応力集中を解消する必要性があった。 そこで本発明は、 上述した問題点に鑑みて案出されたものであり 、 その目的とするところは、 特に初期剛性を高水準に維持しつつ破 断応力を低く抑えることが可能な、 スチールハウスにおける開口壁 の構造を提供することにあり、 その構造は、 垂壁パネルと腰壁パネ ルとの間で挟持されるように側面壁を設け、 この側面壁が固着され る側面壁用枠体を構成する各横枠材に対して、 垂壁パネルの下端部 が固着される開口部上枠材並びに腰壁パネルの上端部が固着される 開口部下枠材を接続金物を介して固着させる。  For this reason, as shown by the behavior of r in the frame around the opening 8, it is necessary to eliminate stress concentration in the steel house by keeping the initial rigidity at a high level and keeping the breaking stress low. was there. Accordingly, the present invention has been devised in view of the above-described problems, and the object of the present invention is to provide a steel house that can keep the breaking strength low while maintaining the initial rigidity at a high level. The side wall is provided with a side wall so that the side wall is sandwiched between the vertical wall panel and the waist wall panel, and the side wall is fixed to the side wall frame. An opening upper frame member to which the lower end portion of the vertical wall panel is fixed and an opening lower frame member to which the upper end portion of the waist wall panel are fixed are fixed to the respective horizontal frame members constituting the through wall fittings.
即ち、 本発明を適用したスチールハウスにおける開口壁の構造は 、 垂壁パネルの下端部が固着される開口部上枠材並びに腰壁パネル の上端部が固着される開口部下枠材と、 これらの両側に立設される 縦枠材とで形成される開口部と、 各縦枠材の外側にそれぞれ配置さ れる外側縦枠材と、 縦枠材並びに外側縦枠材の上端部間及び下端部 間をそれぞれ架設するための横枠材とからなる 2つの側面壁用枠体 と、 側面壁用枠体に固着されてなる側面壁とを備え、 垂壁パネルは 、 水平方向に伸張されて側面壁の上部と一体化され、 腰壁パネルは 、 水平方向に伸張されて側面壁の下部と一体化され、 さらに側面壁 は、 一体化された垂壁パネル並びに腰壁パネルとの間で面材を互い に分割して構成されている。 図面の簡単な説明 That is, the structure of the opening wall in the steel house to which the present invention is applied includes the opening upper frame material to which the lower end portion of the hanging wall panel is fixed, and the opening lower frame material to which the upper end portion of the waist wall panel is fixed, and these Openings formed by vertical frame members erected on both sides, outer vertical frame members respectively arranged on the outer sides of the vertical frame members, and between the upper and lower ends of the vertical frame members and the outer vertical frame members Two side wall frames made up of horizontal frame members for erected between each other, and a side wall fixed to the side wall frame body, the hanging wall panel is extended horizontally It is integrated with the upper part of the wall, the waist wall panel is stretched horizontally and integrated with the lower part of the side wall, and the side wall is a surface material between the integrated vertical wall panel and the waist wall panel. Are divided into each other. Brief Description of Drawings

以下、 本発明を実施するための最良の形態として、 スチールハウ スにおける開口壁の補強構造について、 図面を参照しながら詳細に 説明する。  Hereinafter, as a best mode for carrying out the present invention, a reinforcing structure of an opening wall in a steel house will be described in detail with reference to the drawings.
本発明を適用した補強構造 50は、 図 1〜 3に示すように、 スチー ルハウスの出入口や窓等に代表される開口部 5 1を補強するための構 造である。 この補強構造 50の骨組みは、 図 1， 2に示すように、 下 枠材 52から複数の形枠材 53が所定の間隔をおいて立ち上げられてな り、 各形枠材 53の上端は開口部下枠材 54に固着されている。 また上 枠材 55からは複数の形枠材 56が所定の間隔をおいて立ち下げられて なり、 各形枠材 56の下端は開口部上枠材 57に固着されている。  A reinforcing structure 50 to which the present invention is applied is a structure for reinforcing an opening 51 typified by an entrance / exit of a steel house or a window as shown in FIGS. As shown in Figs. 1 and 2, the framework of this reinforcing structure 50 is composed of a plurality of frame members 53 that are raised from the lower frame member 52 at predetermined intervals. It is fixed to the opening lower frame member 54. A plurality of frame members 56 are lowered from the upper frame member 55 at a predetermined interval, and the lower ends of the frame members 56 are fixed to the upper opening frame member 57.
また、 開口部上枠材 57と開口部下枠材 54との間に形成される開口 部 5 1の両側に立設される縦枠材 58と、 各縦枠材 58の外側にそれぞれ 配置される外側縦枠材 59と、 縦枠材 58と外側縦枠材 59とを架設する ための横枠材 6 1と、 縦枠材 58と外側縦枠材 59とをそれぞれ架設する ための横枠材 62とからなる側面壁用枠体 64が両脇に形成されている さらに、 この補強構造 50は、 下枠材 52から上枠材 55にかけて断面 が長方形状の縦枠材 12 1が立ち上げられてなる。 また、 縦枠材 12 1と 外側縦枠材 59の間には、 中間縦枠材 13 1が下枠材 52から上枠材 55に かけて立ち上げられてなる。 なお、 外側縦枠材 59に関しても同様に 下枠材 52から上枠材 55にかけて立ち上げられるようにしてもよい。  Also, a vertical frame member 58 standing on both sides of the opening 51 formed between the opening upper frame member 57 and the opening lower frame member 54, and arranged outside each vertical frame member 58, respectively. Horizontal frame member 61 for installing the outer vertical frame member 59, the vertical frame member 58 and the outer vertical frame member 59, and the horizontal frame member for installing the vertical frame member 58 and the outer vertical frame member 59, respectively. Further, the side wall frame body 64 made of 62 is formed on both sides. Further, the reinforcing structure 50 has a vertical frame member 121 having a rectangular cross section from the lower frame member 52 to the upper frame member 55. It becomes. Further, between the vertical frame member 121 and the outer vertical frame member 59, an intermediate vertical frame member 131 is started up from the lower frame member 52 to the upper frame member 55. Similarly, the outer vertical frame member 59 may be started up from the lower frame member 52 to the upper frame member 55.
また開口部上枠材 57の両端には、 さらに側面上枠材 157が配設さ れ、 開口部下枠材 54の両端には、 さらに側面下枠材 154が配設され ている。 即ち、 この開口部上枠材 57と側面上枠材 157、 並びに開口 部下枠材 54と側面下枠材 1 54とは、 同一の高さにおいて互いに分割 された状態で配設されている。 また、 縦枠材 1 2 1には、 それぞれ開 口部上枠材 57と側面上枠材 1 57とを架設するための図示しないプレ 一ト、 或いは開口部下枠材 54と側面下枠材 1 54とを架設するための 図示しないプレートを揷通させるための図示しない切り欠きを設け るようにしてもよい。 Further, side upper frame members 157 are further disposed at both ends of the opening upper frame member 57, and side surface lower frame members 154 are further disposed at both ends of the opening lower frame member 54. That is, the opening upper frame member 57, the side upper frame member 157, and the opening The subordinate frame material 54 and the side surface lower frame material 1 54 are arranged in a state of being divided from each other at the same height. The vertical frame member 1 2 1 includes a plate (not shown) for laying the opening upper frame member 57 and the side upper frame member 57, respectively, or the opening lower frame member 54 and the side lower frame member 1 respectively. A notch (not shown) for passing a plate (not shown) for erection with 54 may be provided.
上枠材 5 5と開口部上枠材 57、 側面上枠材 1 57とには、 図 3に示す ような垂壁パネル 7 1が取付けられている。 また、 開口部下枠材 54、 側面下枠材 1 54と下枠材 52とには、 腰壁パネル 72が取付けられてい る。 即ち、 開口部上枠材 57には、 垂壁パネル 7 1の下端部が固着され 、 開口部下枠材 54には、 腰壁パネル 72の上端部が固着されている状 態となる。 なお、 垂壁パネル 7 1並びに腰壁パネル 72の両端は、 外側 縦枠材 59の形成位置付近まで延伸されていてもよい。  A vertical wall panel 71 as shown in FIG. 3 is attached to the upper frame member 5 5, the opening upper frame member 57, and the side upper frame member 1 57. Further, a waist wall panel 72 is attached to the opening lower frame member 54, the side lower frame member 1 54, and the lower frame member 52. That is, the lower end portion of the hanging wall panel 71 is fixed to the upper opening frame member 57, and the upper end portion of the waist wall panel 72 is fixed to the lower opening frame member 54. Note that both ends of the vertical wall panel 71 and the waist wall panel 72 may be extended to the vicinity of the position where the outer vertical frame member 59 is formed.
また、 側面壁用枠体 64には、 側面壁 73が取付けられている。 この 側面壁 73は、 図 3に示すように、 垂壁パネル 7 1と腰壁パネル 72との 間で挟持されるように側面壁用枠体 64に固着されている。  A side wall 73 is attached to the side wall frame 64. As shown in FIG. 3, the side wall 73 is fixed to the side wall frame 64 so as to be sandwiched between the vertical wall panel 71 and the waist wall panel 72.
各枠材は、 いずれも厚さ 1. 0匪〜 1. 6mm程度の薄鋼板を折り曲げ加 ェすることによりウェブとその両端にフランジを一体に連設させた 溝形鋼で構成されている。 下枠材 5 2は、 図 1 に示すようにウェブ 5 2 aと、 ウェブ 5 2 aの両側に設けられたフランジ 52 bで構成され、 か かる下枠材 52の内側に、 ウェブ 53 aとウェブの両側のフランジ 53 b と、 フランジ 53 b先端のリ ップ 53 cからなる形枠材 53が略鉛直方向 から差し込まれてなり、 その重合部には図示しないドリルねじを打 設することにより互いに接合されて構成される。 同様に開口部下枠 材 54は、 ウェブ 54 aと、 ウェブ 54 aの両側に設けられたフランジ 54 bで構成され、 かかる開口部下枠材 54の内側に、 形枠材 53が略鉛直 方向から差し込まれて構成される。 また、 側面下枠材 154と横枠材 62は、 断面が略 H型となるように 互いにウェブの背面同士が貼り合わされる。 そしてこの貼り合わさ れた側面下枠材 154と横枠材 62に対して、 例えばドリルねじ等の接 続金物 8 1を打設することにより互いに接合されることになる。 これ により、 垂壁パネル 71又は腰壁パネル 72の側壁部分が接続金物 8 1に より固着されることになる。 Each frame is made of channel steel with a web and flanges connected to both ends by bending a thin steel plate with a thickness of about 1.0 mm to 1.6 mm. As shown in FIG. 1, the lower frame member 52 is composed of a web 52a and flanges 52b provided on both sides of the web 52a. A frame 53 consisting of a flange 53 b on both sides of the web and a lip 53 c at the end of the flange 53 b is inserted from a substantially vertical direction, and a drill screw (not shown) is placed in the overlap portion. Constructed by joining together. Similarly, the opening lower frame member 54 includes a web 54 a and flanges 54 b provided on both sides of the web 54 a. Inside the opening lower frame member 54, the frame member 53 is inserted from a substantially vertical direction. Configured. Further, the back side of the web is bonded to each other so that the cross section of the side lower frame material 154 and the horizontal frame material 62 is substantially H-shaped. The side lower frame material 154 and the horizontal frame material 62 are bonded to each other by placing a connection metal 81 such as a drill screw. As a result, the side wall portion of the vertical wall panel 71 or the waist wall panel 72 is fixed by the connection hardware 81.
接続金物 8 1は、 ドリルねじに限定されるものではなく、 ポルトと ナッ ト等、 他のいかなる止め具で構成してもよい。 また、 この接続 金物 8 1を打設する代わりに、 溶接等他のいかなる接合手段を用いて も良い。  The connection hardware 8 1 is not limited to a drill screw, and may be composed of any other stopper such as a port and nut. Further, instead of placing the connection hardware 81, any other joining means such as welding may be used.
同様に、 ウェブ 157 aと、 ウェブ 157 aの両側に設けられたフラン ジ 157 bで構成される側面上枠材 157は、 ウェブ 6 1 aとフランジ 6 1 b からなる横枠材 61との間で、 断面が略 H型となるように互いに背面 同士を貼り合して構成される。 そしてこの貼り合わされた側面上枠 材 157と横枠材 6 1に対して、 接続金物 8 1を打設することにより互い に接合されてなる。  Similarly, the side upper frame material 157 composed of the web 157 a and the flange 157 b provided on both sides of the web 157 a is between the horizontal frame material 61 composed of the web 6 1 a and the flange 6 1 b. Thus, the back surfaces are bonded to each other so that the cross section is substantially H-shaped. The side-side upper frame member 157 and the horizontal frame member 61 are joined to each other by placing a connection hardware 81.
次に、 上述の如き補強構造 50を備えるスチールハウスにおいて、 水平力が負荷された場合の挙動について説明をする。  Next, the behavior when a horizontal force is applied in the steel house having the reinforcing structure 50 as described above will be described.
先ず、 スチールハウスに水平力が加わると、 かかる水平力は、 補 強構造 50へ伝達される結果、 補強構造 50全体が水平方向に変形する ことになる。 しかしながら、 本発明を適用した補強構造 50において は、 あくまで側面壁 73の長さは、 従来の開口部の補強構造と比較し て短いため、 側面壁 73の初期剛性そのものは大きくなる。 その結果 、 負荷された水平力が小さい場合には図 4に示すように側面壁 73そ のものの橈み量は小さくなる。 しかしながら、 補強構造 50における 強度的に弱い箇所は少なからずかかる水平力の影響を受けることに なり、 特にかかる側面壁 73が固着される横枠材 6 1 , 62のフランジ 6 1 a， 62 aに打設される接続金物 81は、 かかる水平力に基づいて水平 方向に弾性変形又は塑性変形することになる。 First, when a horizontal force is applied to the steel house, the horizontal force is transmitted to the reinforcing structure 50, so that the entire reinforcing structure 50 is deformed in the horizontal direction. However, in the reinforcing structure 50 to which the present invention is applied, since the length of the side wall 73 is shorter than that of the conventional opening structure, the initial rigidity of the side wall 73 itself is increased. As a result, when the applied horizontal force is small, the amount of stagnation of the side wall 73 is small as shown in FIG. However, the strength structure of the reinforcing structure 50 is not affected by the horizontal force, and the flanges 61, 62 of the horizontal frame members 61, 62 to which the side wall 73 is fixed. The connection hardware 81 placed on a and 62a is elastically or plastically deformed in the horizontal direction based on the horizontal force.
即ち、 従来と比較して、 この補強構造 50は、 側面壁の変形そのも のを抑えることができることから、 スチールハウスに対して僅かな 振動が加わった場合においても、 これを大幅に抑制することが可能 となる。  In other words, compared to the conventional case, this reinforcing structure 50 can suppress the deformation of the side wall itself, and therefore, even when a slight vibration is applied to the steel house, this is greatly suppressed. Is possible.
特に、 この補強構造 50においては、 垂壁パネル 71と、 腰壁パネル 72に対して接続金物 81を介して側面壁 73を連結させているため、 か かる補強構造 50に水平力が加わった場合においても、 垂壁パネルや 腰壁パネルがかかる水平力をある程度分担することができ、 側面壁 In particular, in this reinforcing structure 50, since the side wall 73 is connected to the vertical wall panel 71 and the waist wall panel 72 via the connection hardware 81, a horizontal force is applied to the reinforcing structure 50. The horizontal force applied to the vertical wall panel and the waist wall panel can be shared to some extent.
73の変形はより拘束されることになる。 即ち、 連結された垂壁パネ ル 7 1や腰壁パネル 72により、 側面壁 73に負荷される応力が小さくな るため、 かかる側面壁 73の断面をより小さく設計することも可能と なる。 The deformation of 73 is more restrained. That is, since the stress applied to the side wall 73 is reduced by the connected vertical wall panel 71 and the waist wall panel 72, the cross section of the side wall 73 can be designed to be smaller.
また、 この補強構造 50に対して地震等に基づいて大きな水平力が 加わった場合においても、 側面壁 73は、 初期剛性が高いことから、 図 5に示すように即座に破断することはない。 しかしながら、 補強 構造 50における強度的に弱い箇所がかかる水平力を担うところ、 側 面壁 73の面材が固着される横枠材 6 1， 62のフランジ 6 1 a， 62 aに打 設される ドリルねじ 23 (接続金物） は、 かかる水平力に基づいて変 形し、 最終的にはかかる ドリルねじ 23の接合部が破壊してしまう。 かかる ドリルねじ 23の破壌が、 補強構造 50全体の破壊応力を下げる 要因となる。  Further, even when a large horizontal force is applied to the reinforcing structure 50 based on an earthquake or the like, the side wall 73 does not break immediately as shown in FIG. However, a place where the strength of the reinforcing structure 50 is weak is responsible for the horizontal force, and the drill is placed on the flanges 6 1 a and 62 a of the horizontal frame members 61 and 62 to which the face material of the side wall 73 is fixed. The screw 23 (connecting hardware) is deformed based on the horizontal force, and eventually the joint portion of the drill screw 23 is destroyed. Such rupture of the drill screw 23 causes a reduction in the fracture stress of the entire reinforcing structure 50.
即ち、 この補強構造 50は、 地震等に基づく大きな水平力が加わつ た場合に、 最終的な破壌応力は従来技術と比較してもあまり向上す ることはなく、 スチールハウス全体からみても、 一部分のみに高強 度の構造が設けられている状態を回避することができる。 このため 、 地震等に基づいて大きな水平力がスチールハウスに負荷した場合 に、 開口部周辺の補強構造 50に応力が集中することがなくなり、 ま た他の構成部材に対しても大きな負荷が加わることもなくなる。 In other words, this reinforcing structure 50 does not significantly improve the final rupture stress compared to the prior art when a large horizontal force based on an earthquake or the like is applied. It is possible to avoid a state in which a high-strength structure is provided only in a part. For this reason When a large horizontal force is applied to the steel house due to an earthquake or the like, stress is not concentrated on the reinforcing structure 50 around the opening, and a large load is also applied to other components. Disappear.
図 6は、 開口部の両側に設けられる側面壁の剪断変形量に対する 剪断応力の関係を示している。 本発明を適用した補強構造 50の挙動 uは、 従来の挙動 t と比較して、 初期剛性を高水準に維持しつつ、 破断応力の向上を抑えることができるため、 スチールハウス中の局 所的な応力の集中を抑えることが可能となる。 また、 スチールハウ ス中において、 かかる応力集中に対抗するために他の各構成部材に 対して別途補強部材等を貼り巡らせる必要がなくなることから、 よ り製作コス トや労力の負担を軽減させることが可能となる。  Figure 6 shows the relationship between the shear stress and the shear deformation of the side wall provided on both sides of the opening. Compared with the conventional behavior t, the behavior u of the reinforcing structure 50 to which the present invention is applied can suppress the improvement in breaking stress while maintaining the initial rigidity at a high level. It is possible to suppress stress concentration. In addition, it is not necessary to attach a separate reinforcing member to each other component in order to counter this stress concentration in the steel house, thereby reducing the manufacturing cost and labor burden. Is possible.
なお、 上述した実施の形態においては、 あくまでスチールハウス の窓や出入り口を構成する開口部 51の補強構造 50を例に挙げて説明 したが、 かかる箇所に限定されるものではなく、 スチールハウスを 構成する如何なる開口部に対して適用してもよいことは勿論である  In the embodiment described above, the reinforcing structure 50 of the opening 51 that constitutes the window and entrance of the steel house has been described as an example. However, the present invention is not limited to such a place, and the steel house is configured. Of course, it may be applied to any opening.
