- 10 b is a floor opening side joist
- 10 c is a joist support
- 10 d is a stopper.
- SH method In the building by this steel house method (called SH method), there is no vertical frame material 2 in the openings 8 such as the entrances 8a and 8b. There is no vertical support column to support the vertical load, and the area of the opening 8 is weak in strength. For this reason, it is necessary to reinforce the upper part of the opening 8, and a lintel 15 is provided on the opening 8.
- the upper frame material 3 and the lintel frame material 17 are provided above and below the lintel 15 of the window 8b (opening 8).
- the lintel vertical frame material 1 9 is provided between the material 1 7 and the upper frame material 1 8 of the opening, and both ends of the lintel 1 5 are attached to the lintel support 2 0 via the lintel support 2 1.

- the four sides of the opening 8, that is, the frame material on each side of the rectangle and the frame material located outside of it move laterally, and the left and right lintels located on both sides of the opening 8. Pull-out force and compressive force act on the vertical frame member 2 2 for mounting.
- each wall functions as a resistance wall.
- loose joints were used so that the behavior of the vertical wall 26 and waist wall 2 7 due to horizontal forces such as earthquakes did not affect the side wall 28 and the outer wall. It is said that.
- the behavior of the vertical wall 26 and the waist wall 2 7 and the mutual behavior of the side wall 28 are shown in Fig. 4 (a) and Fig. 5 (a). The force is not transmitted to the vertical wall 2 6 and the waist wall 2 7, so the side wall 2 8 swings independently of the vertical wall 2 6 and the waist wall 2 7 (the problem of this will be described later). .
- Fig. 4 (a) conventionally, when the vertical wall 26 and the waist wall 2 7 and the side wall 28 (horizontal wall) 8 move horizontally due to an earthquake or the like, the vertical wall 2 6 and the waist wall 2 Assuming that the behavior of 7 does not adversely affect the side wall 2 8 (wall), the space between the hanging wall 2 6 and the side wall 2 8 and the space between the waist wall 2 7 and the side wall 2 8 are loose. In this case, the behavior of the vertical wall 26 and the waist wall 2 7 and the mutual behavior of the side wall 28 are as shown in Fig. 5 (a).
- the shear force transmission mechanism is structurally cut by the opening 8 and the vertical walls 2 6 and the waist walls 2 7 on both sides thereof. 28 is less resistant to roll and more horizontal deformation.

- the downward force (pull-out force) and the upward force (compression force) increase.
- the downward force is the sum of the downward arrows of the dotted ellipse (ii) in Fig. 5 (a). Therefore, if this downward force is large, the downward force (pull-out force) also increases. .
- it is necessary to increase the size of the vertical frame material to which the ⁇ 1> side wall 28 (anti-wall) is attached, and 2> hold down hardware to attach the vertical frame material to the foundation, etc. It is necessary to increase the strength by making the anchors for fixing the ⁇ 3> fall-down hardware to the concrete foundation thicker and longer. Pulling like this
- the large pull-out force and compression force increase the size of hole-down hardware, anchors and vertical frames.
- the root of the problem lies in loosely joining the vertical wall 2 6 and the waist wall 2 7 and the side wall 2 8, and the vertical wall 2 6 and the waist wall 2 7 do not function as resistance walls, Unless this problem is solved, the above problem cannot be solved.
- the vertical wall 2 6 and the waist wall 2 7 arranged above and below the opening are made to function as a resistance wall.
- the behavior of the side wall 2 8 is suppressed as much as possible by joining the vertical wall 26, the waist wall 2 7 and the side wall 2 8 to each other so that shearing force can be transmitted.

このスチールハウス工法 ( S H工法という) による建物において 、 出入口 8 a、 8 bなどの開口部 8には縦枠材 2が存在しないこと から、 この開口部 8においては、 屋根等の上階からの鉛直荷重を支 える縦方向の支持柱がなく、 開口部 8の部位は強度的に弱くなる。 このため、 開口部 8の上部を補強する必要があり、 開口部 8の上に まぐさ 1 5を設ける。 In the building by this steel house method (called SH method), there is no vertical frame material 2 in the openings 8 such as the entrances 8a and 8b. There is no vertical support column to support the vertical load, and the area of the opening 8 is weak in strength. For this reason, it is necessary to reinforce the upper part of the opening 8, and a lintel 15 is provided on the opening 8.
図 2 ( a ) 、 図 2 ( b ) に示すよ うに、 窓 8 b (開口部 8 ) のま ぐさ 1 5の上下に上枠材 3 とまぐさ枠材 1 7が設けられ、 まぐさ枠 材 1 7 と開口部上枠材 1 8の間にまぐさ部縦枠材 1 9が設けられ、 まぐさ 1 5の両端が、 まぐさ受け 2 0にまぐさ受け金物 2 1を介し て取付けられ、 まぐさ受け 2 0は、 まぐさ受け取付け用縦枠材 2 2 に固着されている。 まぐさ受け取付け用縦枠材 2 2の下端と上端は 、 下枠材 1 と上枠材 3にドリルねじ 2 3で固着されている。 図 2に おいて、 開口部下枠材 2 4は、 下端を下枠材 1 に固着した開口下部 縦枠材 2 5の上端で支持されている。 2 4 aは受け部材である。 As shown in Fig. 2 (a) and Fig. 2 (b), the upper frame material 3 and the lintel frame material 17 are provided above and below the lintel 15 of the window 8b (opening 8). The lintel vertical frame material 1 9 is provided between the material 1 7 and the upper frame material 1 8 of the opening, and both ends of the lintel 1 5 are attached to the lintel support 2 0 via the lintel support 2 1. The lintel support 20 is fixed to the vertical frame member 2 2 for mounting the lintel support. The lower and upper ends of the vertical frame member 2 2 for attaching the lintel support are fixed to the lower frame member 1 and the upper frame member 3 with drill screws 23. In FIG. 2, the opening lower frame member 24 is supported by the upper end of the opening lower frame member 25 having the lower end fixed to the lower frame member 1. 2 4 a is a receiving member.
図 3に示すよ うに、 開口部下枠材 2 4 とその上方に配置の各枠材 には、 構造用面材が ドリルねじ 2 3で固着されて垂壁 2 6を構成し ている。 また、 開口部下枠材 2 4 とその下方に配置の各枠材には構 造用面材が ドリルねじ 2 3で固着されて腰壁 2 7 を構成している。 As shown in FIG. 3, a structural face material is fixed to each of the opening lower frame member 24 and each frame member disposed above it with a drill screw 23 to form a vertical wall 26. Further, a structural wall material is fixed to the lower frame material 2 4 of the opening and each frame material arranged below it by a drill screw 23 to constitute a waist wall 2 7.
さ らに、 まぐさ受け取付け用縦枠材 2 2 とその両外側の枠材 (縦 枠材 2 a ) には、 構造用面材が ドリルねじ 2 3で固着されて側面壁
2 8を構成している。 In addition, the structural frame material is fixed to the side wall by the drill screw 23 on the vertical frame material 2 2 for attaching the lintel support and the frame materials on both outer sides (vertical frame material 2 a). Consists of 2-8.
前記のよ うに開口部 8の上下左右の 4辺には、 各辺側に配置の枠 材を介して垂壁 2 6 と腰壁 2 7 と側面壁 2 8が配置されることで当 該開口部 8が構成されているが、 この開口部 8内には枠材 (支持柱 ) が存在しないことから、 当該開口部 8の周辺は地震等によ り水平 力が作用したとき強度が不足して変形しやすく、 このとき開口部 8 の 4辺、 つまり矩形の各辺の枠材とその外側に位置する枠材が横移 動して、 開口部 8の両側に位置する、 左右のまぐさ受け取付け用縦 枠材 2 2には引抜力と圧縮力が作用する。 As described above, the vertical wall 2 6, the waist wall 2 7, and the side wall 2 8 are arranged on the four sides of the opening 8 on the upper, lower, left, and right sides through the frame members arranged on the respective sides. Although there is no frame material (support pillar) in the opening 8, the area around the opening 8 lacks strength when a horizontal force is applied due to an earthquake or the like. At this time, the four sides of the opening 8, that is, the frame material on each side of the rectangle and the frame material located outside of it move laterally, and the left and right lintels located on both sides of the opening 8. Pull-out force and compressive force act on the vertical frame member 2 2 for mounting.
この場合、 開口部 8の周辺に取付けられる構造用面材からなる垂 壁 2 6及び腰壁 2 7 と側面壁 2 8が相互に剛結合されていれば、 各 壁が耐カ壁と して機能し、 開口部周辺の枠材の水平力移動を制止す る機能を有するはずである。 しかし、 従来はそれとは反対に、 地震 等の水平力による垂壁 2 6及び腰壁 2 7の挙動が側面壁 2 8および その外側の耐カ壁に影響を及ぼさないように、 相互間が緩い接合と されている。 このときの垂壁 2 6及び腰壁 2 7の挙動と、 側面壁 2 8の相互の挙動は図 4 ( a ) 、 図 5 ( a ) のよ うになり、 側面壁 2 8の揺動に伴うせん断力は垂壁 2 6及び腰壁 2 7に伝達されず、 し たがって、 側面壁 2 8は垂壁 2 6及び腰壁 2 7 とは別に単独で揺動 する (これの問題点については後述する) 。 In this case, if the hanging wall 2 6 and the waist wall 2 7 and the side wall 2 8 made of a structural surface material attached around the opening 8 are rigidly connected to each other, each wall functions as a resistance wall. However, it should have a function to restrain the horizontal force movement of the frame material around the opening. However, in the past, on the contrary, loose joints were used so that the behavior of the vertical wall 26 and waist wall 2 7 due to horizontal forces such as earthquakes did not affect the side wall 28 and the outer wall. It is said that. The behavior of the vertical wall 26 and the waist wall 2 7 and the mutual behavior of the side wall 28 are shown in Fig. 4 (a) and Fig. 5 (a). The force is not transmitted to the vertical wall 2 6 and the waist wall 2 7, so the side wall 2 8 swings independently of the vertical wall 2 6 and the waist wall 2 7 (the problem of this will be described later). .
その他の従来技術 ( 1 ) と して、 特開 2 0 0 0 — 2 3 4 4 0 6号 公報の 「壁構造及び面材貼設方法」 がある。 この従来技術 ( 1 ) は 、 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方法 である。 従来技術 ( 2 ) と して、 特開 2 0 0 1 — 1 6 4 6 4 5号公 報の 「木造住宅の計算方法及びこれを利用して建築された木造住宅 」 がある。 この従来技術 ( 2 ) は、 腰壁と垂壁の計算のみの開示で ある。 従来技術 ( 3 ) と して、 特開 2 0 0 2— 3 8 6 3 0号公報の
「木造住宅」 がある。 この従来技術 ( 3 ) は、 在来木造の構造体に 合板を貼り、 腰壁と垂壁の耐カを見込むよ うにしているが、 本発明 のような骨組 (枠材) の接合構造を開示しておらず、 本発明の課題 である、 腰壁と垂壁に耐カ壁として作用させるための構成に適用で きない。 As another prior art (1), there is a “wall structure and face material pasting method” disclosed in Japanese Patent Application Laid-Open No. 2 00 0-2 3 4 4 0 6. This prior art (1) is a method of shifting the joint portion of the face material of the side wall (sleeve wall) from the position of the plywood of the vertical wall. As a prior art (2), there is a “calculation method of a wooden house and a wooden house built by using this method” disclosed in Japanese Patent Application Laid-Open No. 20 0 1 — 1 6 4 6 4 5. This prior art (2) discloses only the calculation of the waist wall and the vertical wall. As prior art (3), Japanese Patent Laid-Open No. There is a “wooden house”. In this prior art (3), a plywood is attached to a conventional wooden structure so as to allow for resistance against the waist wall and the vertical wall, but the frame (frame material) joint structure as in the present invention is used. It is not disclosed, and cannot be applied to the configuration for causing the waist wall and the vertical wall to act as a resistance wall, which is the subject of the present invention.
図 4 ( a ) に示すよ うに、 従来は、 地震等によ り垂壁 2 6及び腰 壁 2 7 と側面壁 2 8 (耐カ壁) が水平移動するとき、 垂壁 2 6及び 腰壁 2 7の挙動が側面壁 2 8 (耐カ壁) に悪影響を及ぼさないこと を前提にしており、 垂壁 2 6 と側面壁 2 8の間、 腰壁 2 7 と側面壁 2 8の間は緩い接合構造であり、 この場合、 垂壁 2 6及び腰壁 2 7 の挙動と側面壁 2 8の相互の挙動は、 前述の図 5 ( a ) のよ うにな つた。 As shown in Fig. 4 (a), conventionally, when the vertical wall 26 and the waist wall 2 7 and the side wall 28 (horizontal wall) 8 move horizontally due to an earthquake or the like, the vertical wall 2 6 and the waist wall 2 Assuming that the behavior of 7 does not adversely affect the side wall 2 8 (wall), the space between the hanging wall 2 6 and the side wall 2 8 and the space between the waist wall 2 7 and the side wall 2 8 are loose. In this case, the behavior of the vertical wall 26 and the waist wall 2 7 and the mutual behavior of the side wall 28 are as shown in Fig. 5 (a).
すなわち、 開口部両側の側面壁 2 8の相互間は、 せん断力伝達機 構的には、 開口部 8 とその上下の垂壁 2 6 と腰壁 2 7で切断されて おり、 したがって、 両側面壁 2 8は横揺れに対しての抵抗が小さく なり、 水平変形が大きくなる。 さらに、 図 5 ( a ) の矢印のように 下向きの力 (引抜き力) 、 上向きの力 (圧縮力) 、 右向きの力、 左 向きの力が交互に循環的に作用し、 左右の揺れが大きいほど下向き の力 (引抜き力) 、 上向きの力 (圧縮力) が大きくなる。 That is, between the side walls 2 8 on both sides of the opening, the shear force transmission mechanism is structurally cut by the opening 8 and the vertical walls 2 6 and the waist walls 2 7 on both sides thereof. 28 is less resistant to roll and more horizontal deformation. In addition, as shown by the arrows in Fig. 5 (a), downward force (pull-out force), upward force (compression force), rightward force, and leftward force act alternately and cyclically, resulting in large left and right shaking. The downward force (pull-out force) and the upward force (compression force) increase.
特に、 下向きの力 (引抜き力) は、 図 5 ( a ) の点線楕円 ( ii ) の下向きの矢印の合計であるので、 この下向きの力が大きければ、 下向きの力 (引抜き力) も大きくなる。 この引抜き力に抵抗するた め < 1 >側面壁2 8 (耐カ壁) を取付ける縦枠材を大型化する必要 があると共に、 く 2 >縦枠材を基礎等に取付けるためのホールダウ ン金物も堅牢にするため大型化する必要があり、 さらに、 < 3 >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も太 くかつ長くするなどによ り強度を高める必要がある。 このよ うに引
抜力と圧縮力が大であるこ とにより、 ホールダウン金物、 アンカー 、 縦枠が大型化する。 In particular, the downward force (pull-out force) is the sum of the downward arrows of the dotted ellipse (ii) in Fig. 5 (a). Therefore, if this downward force is large, the downward force (pull-out force) also increases. . In order to resist this pulling force, it is necessary to increase the size of the vertical frame material to which the <1> side wall 28 (anti-wall) is attached, and 2> hold down hardware to attach the vertical frame material to the foundation, etc. It is necessary to increase the strength by making the anchors for fixing the <3> fall-down hardware to the concrete foundation thicker and longer. Pulling like this The large pull-out force and compression force increase the size of hole-down hardware, anchors and vertical frames.
前記問題の根本は垂壁 2 6及び腰壁 2 7 と側面壁 2 8を緩く接合 していることにあり、 垂壁 2 6及び腰壁 2 7は耐カ壁と しては機能 しておらず、 この問題を解決しない限り前記の問題は解決できない The root of the problem lies in loosely joining the vertical wall 2 6 and the waist wall 2 7 and the side wall 2 8, and the vertical wall 2 6 and the waist wall 2 7 do not function as resistance walls, Unless this problem is solved, the above problem cannot be solved.
発明の開示 Disclosure of the invention
前記の問題を解決するためには、 開口部の上下に配置の垂壁 2 6 及び腰壁 2 7を耐カ壁として機能させる。 つま り、 垂壁 2 6及び腰 壁 2 7 と側面壁 2 8を相互にせん断力伝達可能に接合することで側 面壁 2 8の挙動を極力押さえ込むことである。 これは従来の垂壁 2 6及び腰壁 2 7 と両側面壁との緩い結合構造とは逆の発想であり、 本発明者は、 このよ うに従来殆ど作用しなかった垂壁 2 6及び腰壁 2 7をせん断パネルと して有効に利用することで、 前記側面壁 2 8 の水平変形を抑えることができ、 さ らに、 前記側面壁 2 8に作用す る引抜き力と圧縮力を抑えることができる との知見を得た。 In order to solve the above-described problem, the vertical wall 2 6 and the waist wall 2 7 arranged above and below the opening are made to function as a resistance wall. In other words, the behavior of the side wall 2 8 is suppressed as much as possible by joining the vertical wall 26, the waist wall 2 7 and the side wall 2 8 to each other so that shearing force can be transmitted. This is the opposite concept to the conventional loosely coupled structure of the vertical wall 26 and the waist wall 2 7 and both side walls. By effectively using as a shear panel, horizontal deformation of the side wall 28 can be suppressed, and furthermore, pulling force and compression force acting on the side wall 28 can be suppressed. And gained knowledge.

Each wall is constructed by fixing structural face materials with drill screws to a thin lightweight steel frame. More specifically, in the vertical wall 26, the structural face material is fixed to the upper frame material 3, the opening upper frame material 18 and the lintel vertical frame material 19 with a drill screw. On the waist wall 2 7, the structural face material is fixed to the lower frame material 1, the opening lower frame material 2 4, and the opening lower vertical frame material 25 with a drill screw.

The specific structure of the connecting hardware 29 may be arbitrary. For example, as shown in FIGS. 7 and 8, the reinforcement is made of a thin lightweight steel having the same cross section as the upper and lower frame members 1 8 and 2 4 of the opening. You may comprise for frame material 29a. In addition, the reinforcement frame 29a is composed of L-shaped steel with a predetermined length penetrating the lintel support mounting frame 2 2 to the left and right. The connecting steel materials 33 may be combined (details will be described later with reference to FIG. 9, FIG. 10 (a) and FIG. 10 (b)).
側面壁 2 8では、 構造用面材 7 を、 上枠材 3、 下枠材 1 と、 まぐ さ受け取付け用縦枠材 2 2 と、 これの外方に平行に立ち上がる縦枠 材 2 aに ドリルねじ 2 3で固着することに加えて、 接続金物 2 9に も ドリルねじ 2 3によ り固着する。 したがって、 上枠材 3、 下枠材 1 と、 開口部上枠材 1 8 と開口部下枠材 2 4に構造用面材が ドリル ねじ 2 3で固着された垂壁 2 6 と腰壁 2 7 と側面壁 2 8 とが接続金 物 2 9 を介して、 せん断力伝達可能に強固に結合されることになる 図 6 ( a ) 、 図 6 ( b ) 、 図 7、 図 8に示す構成の開口壁の補強 構造において、 地震などによ り水平力が作用した場合の各壁が変位 する態様は図 4 ( b ) に示されている。 同図において、 開口部 8の 4辺に位置し、 矩形を形成する垂壁 2 6 と腰壁 2 7 と両側面壁 2 8 が、 下辺 3 0を固定部と してその上部が左右に水平移動する とき、 垂壁 2 6 と両側面壁 2 8および腰壁 2 7 と両側面壁 2 8は上下の各 接続金物 2 9を介して堅固に接合されているから、 相互間に従来の ような開き (図 4 ( a ) および図 5 ( a ) に示す) が生じない。 つ まり、 垂壁 2 6及び腰壁 2 7 と両側面壁 2 8が相互にせん断力を伝 達し合うもので、 このとき垂壁 2 6及び腰壁 2 7が、 せん断パネル として水平力に抵抗するよ う有効に機能し、 両側面壁 2 8の揺動を 低減するのに寄与する。 したがって、 側面壁 2 8の剛性が大幅に向 上する。 On the side wall 2 8, the structural face material 7 is changed into the upper frame material 3, the lower frame material 1, the vertical frame material 2 2 for attaching the lintel support, and the vertical frame material 2 a that rises in parallel to the outside of this. In addition to being secured with the drill screw 2 3, it is also secured to the connection hardware 2 9 with the drill screw 2 3. Therefore, the upper frame material 3, the lower frame material 1, the opening upper frame material 1 8 and the opening lower frame material 2 4 and the vertical wall 2 6 and the waist wall 2 7 in which the structural face material is secured to the opening screw frame 2 3 And the side wall 2 8 are firmly connected to each other through the connecting metal 2 9 so that shearing force can be transmitted. The configurations shown in FIGS. 6 (a), 6 (b), 7 and 8 are used. Figure 4 (b) shows how each wall is displaced when a horizontal force is applied due to an earthquake in the reinforcement structure of the opening wall. In this figure, the hanging wall 2 6, waist wall 2 7, and both side walls 2 8, which are located on the four sides of the opening 8, form a rectangle, and the upper part horizontally moves horizontally with the lower side 30 as the fixed part. When the vertical wall 2 6 and the side wall wall 2 8 and the waist wall 2 7 and the side wall wall 2 8 are firmly joined to each other through the upper and lower connecting hardware 2 9, the conventional opening ( Fig. 4 (a) and Fig. 5 (a)) do not occur. In other words, the vertical wall 2 6 and the waist wall 2 7 and the side walls 2 8 transmit shearing force to each other. At this time, the vertical wall 2 6 and the waist wall 2 7 resist the horizontal force as a shear panel. It functions effectively and contributes to reducing the swing of both side walls 28. Therefore, the rigidity of the side wall 28 is greatly improved.
図 5 ( b ) でさ らに説明する と、 下辺 3 0を固定部としてその上 部が左右に水平移動するとき、 垂壁 2 6 と両側面壁 2 8および、 腰 壁 2 7 と両側面壁 2 8に矢印方向の力が流れる。 つま り、 垂壁 2 6 と両側面壁 2 8および、 腰壁 2 7 と両側面壁 2 8は接続金物 2 9で
堅牢に結合されていることで、 開口周辺の矩形の壁面で力の伝達が 変化し、 4つの隅部 3 1では矢印の力の流れとなる。 また、 垂壁 2 6の下端縁の延長線 ( i ) と腰壁 2 7の上端縁の延長線 ( i ) で挟 まれる範囲の両側面壁 2 8に矢印の力が流れる。 さらに、 垂壁 2 6 と腰壁 2 7の面内でも矢印の力が流れる。 In Fig. 5 (b), when the lower side 30 is fixed and the upper part moves horizontally from side to side, the hanging wall 2 6 and both side walls 2 8 and the waist wall 2 7 and both side walls 2 The force in the direction of the arrow flows through 8. In other words, the hanging wall 2 6 and the side walls 2 8 and the waist wall 2 7 and the side walls 2 8 Due to the solid connection, the transmission of force changes on the rectangular wall around the opening, and the force flows as indicated by the arrows at the four corners 31. Further, the force of the arrow flows through the side wall 28 in the range sandwiched between the extension line (i) of the lower end edge of the vertical wall 26 and the extension line (i) of the upper end edge of the waist wall 27. Furthermore, the force of the arrow also flows in the plane of the hanging wall 2 6 and the waist wall 2 7.
このよ うに垂壁 2 6 と腰壁 2 7 と両側面壁 2 8 とが、 相互に堅牢 に結合されていることで、 矩形壁面が一体に形成される結果、 下辺 3 0を固定部として上部が水平移動する とき、 矩形の枠では図 5 ( b ) のよ うに 8つに区画された領域で力は矢印の方向に流れ、 しか も隣り合う領域では力の方向が逆方向になつていることで、 相互に 打ち消し合い、 又は弱め合うので、 力が増幅されて次の区画部へ伝 達されることがない。 図 5 ( b ) において、 引抜力は点線の楕円 ( ϋ ) の内の矢印の合計であるが、 側面壁 2 8でみた場合、 図 5 ( b ) と ( a ) の矢印を比較して分るように、 本発明のほうが力の方向 が弱められていて、 下辺 3 0に下向きの矢印で示す引き抜き力が弱 く、 これに伴って、 下辺 3 0に上向きの矢印で示す圧縮力も小さ く なることが分る。 In this way, the vertical wall 2 6, the waist wall 2 7, and the side walls 2 8 are firmly connected to each other, so that the rectangular wall surface is integrally formed. When moving horizontally, in the rectangular frame, the force flows in the direction of the arrow in the area divided into eight as shown in Fig. 5 (b), and in the adjacent area, the direction of the force is in the opposite direction. Because they cancel each other or weaken each other, the force is not amplified and transmitted to the next compartment. In Fig. 5 (b), the pull-out force is the sum of the arrows within the dotted ellipse (ϋ), but when viewed from the side wall 28, the arrows in Fig. 5 (b) and (a) are compared. As shown, the direction of the force is weakened in the present invention, and the pulling force indicated by the downward arrow on the lower side 30 is weak, and accordingly, the compressive force indicated by the upward arrow on the lower side 30 is also small. I know that
本発明によると、 上向きの力 (圧縮力) と下向きの力 (引抜き力 ) が共に小さいので、 まぐさ受け取付け用縦枠材 2 2 と縦枠材 2 a を小型化できる。 また、 まぐさ受け取付け用縦枠材 2 2.と縦枠材 2 aを基礎等に取付けるためのホールダウン金物も強度は小さくてよ いので小型化できる。 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も強度は小さくてよいので小型化でき る。 According to the present invention, since the upward force (compression force) and the downward force (pull-out force) are both small, the vertical frame member 2 2 and the vertical frame member 2 a for attaching the lintel support can be reduced in size. In addition, the hole-down hardware for attaching the vertical frame material 2 2. and the vertical frame material 2a to the foundation or the like can be reduced in size because the strength can be small. Furthermore, the anchor for fixing the hole-down hardware to the concrete foundation can also be reduced in size because it can be low in strength.
