Description

波型鋼板使用の耐力壁Bearing wall using corrugated steel
　この発明は、鉄骨のフレーム材と耐力要素となる波型鋼板とでなる波型鋼板使用の耐力壁に関する。 The present invention relates to a load-bearing wall using a corrugated steel plate composed of a steel frame material and a corrugated steel plate as a load bearing element.
　鉄骨のパネルフレームに波型鋼板を取付け、繰り返し荷重の作用時に、スリップ性状の生じない安定したエネルギー吸収能力を得るようにしたものが知られている（例えば特許文献１，２）。 It is known that a corrugated steel plate is attached to a steel frame so as to obtain a stable energy absorption capability that does not cause slip properties when a repeated load is applied (for example, Patent Documents 1 and 2).
特開２０１０－９０６５０号公報JP 2010-90650 A 特開２０１０－１２６９６４号公報JP 2010-126964 A
　上記特許文献１，２等の従来の技術は、パネル幅の全幅に渡って１枚の波型鋼板を張っているが、スリップ性状のない安定したエネルギー吸収能力を示す範囲に限界がある。従来の全幅に渡る波型鋼板では、層間変位角が１／６６ rad程度で引っ張り挙動に移行し、スリップ性状を示し始める。そのため、パネル幅が限界幅を超えた場合は、必要とする層間変位角に対応できない。波型鋼板の波型の折り曲げ形状を変えることで、限界幅をある程度は増やすことができるが、これにも限りがあり、また特殊な折り曲げ形状の波型鋼板を使用するとコスト高となる。 Although the conventional techniques such as Patent Documents 1 and 2 have a single corrugated steel sheet extending over the entire width of the panel, there is a limit to the range in which stable energy absorption capability without slip properties is exhibited. In the conventional corrugated steel sheet over the entire width, when the interlaminar displacement angle is about 1/66 mm rad, it shifts to a tensile behavior and begins to show slip properties. Therefore, when the panel width exceeds the limit width, the required interlayer displacement angle cannot be handled. By changing the corrugated folding shape of the corrugated steel sheet, the limit width can be increased to some extent, but this is also limited, and the use of special corrugated corrugated steel sheets increases the cost.
　この発明の目的は、壁全体の幅寸法や高さ寸法が１枚の波型鋼板ではスリップ性状を示し始める限界幅を超えても、波型鋼板の折り曲げ形状を変えずに、スリップ性状のない安定したエネルギー吸収能力を確保することができる波型鋼板使用の耐力壁を提供することである。
　この発明の他の目的は、上記のように限界幅を超えても安定したエネルギー吸収能力を確保しながら、加工工数が少なくて済み、製造コストの増加を抑えることである。 The object of the present invention is to have no slip property without changing the bent shape of the corrugated steel sheet even when the width and height of the entire wall exceed the limit width where the corrugated steel sheet starts to exhibit slip property. The object of the present invention is to provide a load-bearing wall using corrugated steel sheets that can secure a stable energy absorption capacity.
Another object of the present invention is to reduce the number of processing steps and suppress an increase in manufacturing cost while ensuring a stable energy absorption capability even when exceeding the limit width as described above.
　この発明の波型鋼板使用の耐力壁は、左右のフレーム材と、これら左右のフレーム材の上端間および下端間に接合された上下のフレーム材と、前記左右のフレーム材および上下のフレーム材で囲まれる壁面区画に張られて耐力要素となる波型鋼板とを備えた耐力壁において、前記波型鋼板を、山部稜線方向と直交して設けられて荷重の伝達を遮断または低下させる荷重伝達分離部によって分け、この荷重伝達分離部に沿って前記壁面区画内に横方向または縦方向に延びる中桟を設け、前記波型鋼板を、波の谷部で前記中桟および前記フレーム材に固定したことを特徴とする。
　前記荷重伝達分離部は、この部分の両側の波型鋼板部分を相互に完全に分離するものであっても、また両側の波型鋼板部分が繋がってはいるが荷重の伝達を遮断または低下させるものであっても良い。また、前記各フレーム材は、独立した耐力壁パネルを構成するパネルフレーム材であっても、建物の柱や梁であっても良い。 The load-bearing walls using corrugated steel sheets according to the present invention include left and right frame members, upper and lower frame members joined between upper and lower ends of the left and right frame members, and the left and right frame members and the upper and lower frame members. In a load bearing wall provided with a corrugated steel sheet that is stretched around a wall section surrounded by the corrugated steel sheet and serves as a load bearing element, the corrugated steel sheet is provided perpendicular to the direction of the ridge line to interrupt or reduce load transmission. Divided by a separating portion, an intermediate beam extending in the horizontal direction or the vertical direction is provided in the wall surface section along the load transmission separating portion, and the corrugated steel plate is fixed to the intermediate beam and the frame material at a wave trough. It is characterized by that.
Even if the load transmission separating portion completely separates the corrugated steel plate portions on both sides of this portion from each other, the load corrugated steel plate portions on both sides are connected, but the load transmission is cut off or reduced. It may be a thing. Each frame material may be a panel frame material constituting an independent load-bearing wall panel, or a building column or beam.
　この構成によると、耐力壁に面内せん断力が負荷された場合に、波型鋼板の波の山部が稜線方向と略直交する方向に歪むことにより、上記面内せん断力に対してスリップ性状のない安定したエネルギー吸収が行われる。この安定したエネルギー吸収が行える波型鋼板の波山稜線方向の幅については限界があるが、この発明では、波型鋼板を山部稜線方向と直交する荷重伝達分離部によって分けており、その分けられた両側の波型鋼板部分は相互に荷重の伝達が遮断されまたは低下する。また、波型鋼板は、波の谷部で固定されることで、前記エネルギー吸収の機能を発揮するが、前記荷重伝達分離部が前記中桟および前記フレーム材に固定れることで、各波型鋼板部分毎に独立して前記山部の歪みによるエネルギー吸収作用が得られる。したがって、その分けられた両側の波型鋼板部分を限界幅以下に設定することで、耐力壁の全体幅が広くても、波型鋼板の折り曲げ形状を変えずに、必要とする層間変形角に対応することができる。
　このように、耐力壁の全体の幅寸法や高さ寸法が１枚の波型鋼板では前記限界幅を超える寸法である場合であっても、波型鋼板の折り曲げ形状を変えずに、スリップ性状のない安定したエネルギー吸収能力を確保することができる。 According to this configuration, when an in-plane shear force is applied to the bearing wall, the wave crest of the corrugated steel sheet is distorted in a direction substantially perpendicular to the ridge line direction, so that the slip property against the in-plane shear force. Stable energy absorption without any problem. Although there is a limit to the width of the corrugated steel sheet that can stably absorb energy, the corrugated steel sheet is divided by the load transmission separating portion orthogonal to the ridge ridge line direction. In addition, the transmission of the load between the corrugated steel plate portions on both sides is interrupted or reduced. In addition, the corrugated steel sheet exhibits the energy absorption function by being fixed at the wave troughs, but each corrugation is achieved by the load transmission separating part being fixed to the middle rail and the frame material. The energy absorption effect by the distortion of the peak portion can be obtained independently for each steel plate portion. Therefore, by setting the corrugated steel sheet portions on both sides that are separated to be less than the limit width, even if the total width of the load bearing wall is wide, the bending deformation of the corrugated steel sheet is not changed and the required interlayer deformation angle is achieved. Can respond.
In this way, even if the entire width dimension and height dimension of the bearing wall is a dimension that exceeds the limit width in one corrugated steel sheet, the slip property is maintained without changing the bent shape of the corrugated steel sheet. It is possible to secure a stable energy absorption capacity without any problems.
　この発明において、前記荷重伝達分離部は、前記波型鋼板の少なくとも山部に設けられたスリットであっても良い。
　前記波型鋼板を完全に分離された複数枚に分けた場合、波型鋼板をフレーム材に取付ける際に位置合わせが複雑になる。また、複数枚製造するため、同一面積当たりの工数が増え、製造コストが増加する。しかし、上記のように荷重伝達分離部をスリットとした場合、荷重伝達分離部で分離されていない１枚の大きな波型鋼板を使用できる。そのため、荷重伝達分離部の両側の波型鋼板部分を相互に位置合わせする工程が不要であり、位置合わせ工程の増加によるコトス増が解消できる。スリットの加工は必要であるが、前記位置合わせに比べて簡単な工程で済む。
　このようにスリットを設けることで、上記のように限界幅を超えても安定したエネルギー吸収能力を確保しながら、加工工数が少なくて済み、製造コストの増加を抑えることができる。 In the present invention, the load transmission separating portion may be a slit provided at least in the peak portion of the corrugated steel sheet.
When the corrugated steel sheet is divided into a plurality of completely separated sheets, the positioning becomes complicated when the corrugated steel sheet is attached to the frame material. In addition, since a plurality of sheets are manufactured, the number of steps per the same area increases and the manufacturing cost increases. However, when the load transmission separation part is a slit as described above, one large corrugated steel sheet that is not separated by the load transmission separation part can be used. Therefore, the process of aligning the corrugated steel sheet portions on both sides of the load transmission separation part with each other is unnecessary, and the increase in cost due to the increase in the alignment process can be eliminated. The slits need to be processed, but the steps are simpler than the alignment.
By providing the slits in this way, it is possible to reduce the number of processing steps and secure an increase in manufacturing cost while securing a stable energy absorption capability even when the limit width is exceeded as described above.
　この発明において、中桟として１本以上の横桟を設け、この横桟により前記壁面区画が上下に分割される分割区画毎に、前記波型鋼板として、互いに分割された複数の分割波型鋼板を設けても良い。
　この構成の場合、波型鋼板が上下に分割された複数の分割波型鋼板とされることで、上下幅の広い耐力壁であっても、上下幅の広い波型鋼板を使用することなく、耐力壁が製作できる。また、その各分割波型鋼板の山部稜線方向が上下方向である場合は、上下に分割された複数の分割波型鋼板とされることで、安定したエネルギー吸収機能についての限界幅に対応して波型鋼板が分割されることになり、上下幅の広い耐力壁の場合に、波型鋼板の折り曲げ形状を変えずに、スリップ性状のない安定したエネルギー吸収能力を確保することができる。 In this invention, one or more horizontal rails are provided as intermediate rails, and a plurality of divided corrugated steel sheets that are divided from each other as the corrugated steel sheets for each of the divided sections in which the wall surface sections are vertically divided by the horizontal rails. May be provided.
In the case of this configuration, the corrugated steel sheet is a plurality of divided corrugated steel sheets divided into upper and lower parts, even if the load bearing wall has a wide vertical width, without using a corrugated steel sheet with a wide vertical width, Bearing walls can be manufactured. In addition, when the ridge line direction of each of the split corrugated steel sheets is the vertical direction, it corresponds to the limit width for the stable energy absorption function by being divided into plural split corrugated steel sheets. Thus, the corrugated steel sheet is divided, and in the case of a load-bearing wall having a wide vertical width, it is possible to ensure a stable energy absorption capability without slip property without changing the bent shape of the corrugated steel sheet.
　この場合に、前記横桟の他に、前記中桟となる縦桟を設け、前記分割波型鋼板は山部稜線方向が横方向とされ、かつこの分割波型鋼板は前記縦桟に沿って前記荷重伝達分離部となるスリットを有するものとしても良い。
　波型鋼板におけるスリップ性状のない安定したエネルギー吸収が行われる限界幅は、山部稜線方向についての幅である。分割波型鋼板の横方向が山部稜線方向となる場合は、このように縦桟に沿って前記荷重伝達分離部となるスリットを有することで、横幅が広い耐力壁の場合にも、波型鋼板の折り曲げ形状を変えずに、スリップ性状のない安定したエネルギー吸収能力を確保することができる。 In this case, in addition to the horizontal beam, a vertical beam serving as the middle beam is provided, and the split corrugated steel sheet has a mountain ridge line direction as a horizontal direction, and the split corrugated steel sheet extends along the vertical rail. It is good also as what has a slit used as the above-mentioned load transmission separation part.
The limit width in which the stable energy absorption without slip property in the corrugated steel sheet is performed is the width in the ridge line direction. When the transverse direction of the split corrugated steel sheet is the ridge line direction, the corrugated corrugated steel plate has a slit that becomes the load transmission separation part along the vertical rail in this way, even in the case of a load bearing wall having a wide lateral width. A stable energy absorption capability without slip properties can be ensured without changing the bent shape of the steel sheet.
　波型鋼板に前記荷重伝達分離部としてスリットを設ける場合に、前記波型鋼板は波山の頂部および波山の底部が平坦部分となる断面矩形または台形の波形であり、前記スリットは、前記波谷の底部となる平坦部分を除く全範囲に渡って設け、前記スリットの幅を５mm以上としても良い。
　前記スリットを波谷の底部となる平坦部分を除く全範囲に渡って設けることで、スリットが長くなり、連続する部分が平坦な谷底部分だけとなって、スリットの両側の部分間での荷重の伝達がより生じ難くなる。そのため、スリットの両側の部分を相互に独立させてエネルギー吸収を行わせる機能が増大し、より安定してエネルギー吸収能力が確保できる。また、スリットの幅が５mm以上であると、変形時においてスリットで分離される山部間での干渉が無く、この点からも安定したエネルギー吸収能力を確保することができる。 When a slit is provided in the corrugated steel sheet as the load transmission separation part, the corrugated steel sheet has a rectangular or trapezoidal waveform in which the top of the corrugation and the bottom of the corrugation are flat parts, and the slit is the bottom of the corrugated valley The width of the slit may be 5 mm or more provided over the entire range excluding the flat portion.
By providing the slit over the entire range excluding the flat part that becomes the bottom of the wave valley, the slit becomes long, and the continuous part becomes only the flat bottom part, and the load is transmitted between the parts on both sides of the slit. Is less likely to occur. Therefore, the function of absorbing energy by making the portions on both sides of the slit independent from each other increases, and the energy absorption capability can be secured more stably. Further, when the slit width is 5 mm or more, there is no interference between the peaks separated by the slit at the time of deformation, and a stable energy absorbing ability can be ensured also from this point.

As shown in the front view of FIG. 1, the load-bearing wall 1 using the corrugated steel sheet includes upper and lower frame members 2, 2 and upper and lower frames joined between upper and lower ends of the left and right frame members 2, 2. A panel frame 1 composed of frame members 3 and 3 and a corrugated steel sheet 7 stretched on a wall section 6 (FIG. 2) surrounded by the left and right and upper and lower frame members 2, 2, 3 and 3 and serving as a strength element. Prepare. In FIG. 1, the corrugated cross-sectional shape of the corrugated steel sheet 7 and the dimensions of each member are shown together.
Here, the left and right frame members 2 and 2 are provided along the side surfaces of the pillars 11 separately from the left and right columns 11 and 11. , 2, the left and right frame members 2, 2 may be omitted.
　図２のように、前記左右のフレーム材２，２と上下のフレーム材３，３とで矩形のパネルフレーム１が構成される。このパネルフレーム１の壁面区画６内には、横方向に延びる中桟となる横桟４と縦方向に延びる中桟となる縦桟５とが設けられている。横桟４は、前記壁面区画６を上下に並ぶ複数（図示の例では４つ）の分割区画６Ａに等分するように上下に等間隔に複数（図示の例では３本）設けられる。縦桟５は、左右のフレーム材２，２の中間位置に１本設けられる。前記左右および上下のフレーム材２，３、横桟４および縦桟５は、いずれも角形鋼管，溝形鋼、その他の軽量形鋼等の鉄骨材からなる。また、これらフレーム材２，３、横桟４および縦桟５には、前記波型鋼板７を固定するための複数のボルト挿通孔（図示せず）がそれぞれ設けられている。 As shown in FIG. 2, a rectangular panel frame 1 is constituted by the left and right frame members 2, 2 and the upper and lower frame members 3, 3. In the wall surface section 6 of the panel frame 1, there are provided a horizontal beam 4 serving as a middle beam extending in the horizontal direction and a vertical beam 5 serving as a middle beam extending in the vertical direction. A plurality of (three in the illustrated example) horizontal bars 4 are provided at equal intervals in the vertical direction so as to equally divide the wall section 6 into a plurality of (four in the illustrated example) divided sections 6A arranged vertically. One vertical bar 5 is provided at an intermediate position between the left and right frame members 2 and 2. The left and right and upper and lower frame members 2 and 3, the horizontal beam 4 and the vertical beam 5 are all made of a steel frame material such as a square steel pipe, a grooved steel, and other lightweight steel. Further, a plurality of bolt insertion holes (not shown) for fixing the corrugated steel sheet 7 are provided in the frame members 2 and 3, the horizontal rail 4 and the vertical rail 5, respectively.
　波型鋼板７は、一方向に延びる山部７ａと谷部７ｂ（図４Ａ, 図４Ｂ）とが交互に並ぶ断面波形の鋼板であり、ここでは波山稜線方向が横方向に延びるように、すなわち波の山部７ａおよび谷部７ｂの延びる方向が横方向となるように前記壁面区画６に張られている。波型鋼板７の波形は、波山となる山部７ａの頂部および波谷となる谷部７ｂの底部が平坦部分となる断面矩形または台形である。 The corrugated steel sheet 7 is a corrugated steel sheet in which crests 7a and troughs 7b (FIG. 4A, FIG. 4B) extending in one direction are alternately arranged. Here, the corrugated ridge line direction extends in the lateral direction, that is, It is stretched on the wall surface section 6 so that the direction in which the wave crests 7a and troughs 7b extend is the horizontal direction. The waveform of the corrugated steel sheet 7 is a cross-sectional rectangle or trapezoid in which the top of the crest 7a that becomes the wave crest and the bottom of the trough 7b that becomes the wave trough are flat.
　１枚の耐力壁における波型鋼板７は、上下に並ぶ４枚の分割波型鋼板７Ａからなり、各分割波型鋼板７Ａは波の谷部７ｂに沿って互いに分割されている。各分割波型鋼板７Ａは、それぞれ別個に製造されたものであっても、また、互いに切断されたものであっても良い。各分割波型鋼板７Ａは、前記壁面区画６を前記横桟４で等分した各分割区画６Ａ（図２）にそれぞれ張られる。これら４枚の分割波型鋼板７Ａの横幅方向中間位置には、山部稜線方向と直交して荷重の伝達を低下させる荷重伝達分離部となるスリット８が設けられ、このスリット８により各分割波型鋼板７Ａは左右の波型鋼板部分７Ａａ，７Ａａに分けられる。 The corrugated steel sheet 7 in one bearing wall is composed of four split corrugated steel sheets 7A arranged one above the other, and the respective split corrugated steel sheets 7A are divided from one another along the wave troughs 7b. Each of the divided wave steel plates 7A may be manufactured separately or may be cut from each other. Each divided corrugated steel sheet 7A is stretched on each divided section 6A (FIG. 2) obtained by equally dividing the wall section 6 by the cross rail 4. A slit 8 serving as a load transmission separating portion that reduces the load transmission perpendicular to the ridge line direction is provided at an intermediate position in the width direction of the four divided wave steel plates 7A. The steel plate 7A is divided into left and right corrugated steel plate portions 7Aa and 7Aa.
　図３は、図１における分割波型鋼板７Ａの略１枚部分を拡大して示している。前記スリット８は、図３のIVＡを拡大した正面図とその断面図とを示す図４Ａ，図４Ｂのように、分割波型鋼板７Ａの波谷である谷部７ｂの底部となる平坦部分を除く全範囲に渡って、波の山である山部７ａに設けられる。この例では、スリット８の両端が、谷部７ｂの底部となる平坦部分の端まで延びている。このスリット８の幅ｄは、５mm以上とされている。縦方向に延びる中桟である前記縦桟５（図１～図３）は、前記スリット８に沿って設けられる。図３のように、各分割波型鋼板７Ａは、波の谷部７ｂで前記フレーム材２，３、横桟４および縦桟５にボルト１０（図４Ａ）を用いて固定されている。ボルト１０は、波の山部稜線方向と直交する方向に複数本並べて設けられる。 FIG. 3 shows an enlarged view of approximately one portion of the split wave steel plate 7A in FIG. The slit 8 excludes a flat portion serving as a bottom portion of a trough portion 7b which is a corrugated valley of the split wave steel plate 7A as shown in FIGS. 4A and 4B showing an enlarged front view and a cross-sectional view of the IVA in FIG. It is provided in the peak part 7a which is a peak of a wave over the whole range. In this example, both ends of the slit 8 extend to the end of the flat portion that becomes the bottom of the valley portion 7b. The width d of the slit 8 is 5 mm or more. The vertical beam 5 (FIGS. 1 to 3), which is a middle beam extending in the vertical direction, is provided along the slit 8. As shown in FIG. 3, each of the split corrugated steel plates 7A is fixed to the frame members 2 and 3, the horizontal rails 4 and the vertical rails 5 using bolts 10 (FIG. 4A) at wave troughs 7b. A plurality of bolts 10 are provided side by side in a direction orthogonal to the direction of the ridge line of the wave.
　この構成の波型鋼板使用の耐力壁によると、パネルフレーム１に波型鋼板７が張られているため、面内せん断力が負荷された場合に、波型鋼板７の波の山部が稜線方向と略直交する方向に歪むことにより、上記面内せん断力に対してスリップ性状のない安定したエネルギー吸収が行われる。この安定したエネルギー吸収が行える波型鋼板の波山稜線方向の幅については限界があるが、上下に並ぶ各分割波型鋼板７Ａを山部稜線方向と直交するスリット８によって分けており、その分けられた両側の波型鋼板部分７Ａａ，７Ａａは相互に荷重の伝達が遮断されまたは低下する。また、波型鋼板は、波の谷部で固定されることで、前記エネルギー吸収の機能を発揮するが、前記各波型鋼板部分７Ａａ，７Ａａにおける前記スリット８による荷重伝達分離部となる辺が前記中桟である縦桟５に固定され，他の各辺が横桟４および縦フレーム材２に固定されることで、各波型鋼板部分７Ａａ，７Ａａ毎に独立して前記山部の歪みによるエネルギー吸収作用が得られる。したがって、その分けられた両側の波型鋼板部分７Ａａ，７Ａａの横幅を限界幅以下に設定することで、耐力壁の全体幅が広くても、波型鋼板の折り曲げ形状を変えずに、必要とする層間変形角に対応することができる。この例では、パネル横幅７５０mmに対して、波型鋼板部分７Ａａ，７Ａａの横幅は、その半分の３７５mmに分割されており、この波型鋼板部分横幅の３７５mmが前記限界幅以下であれば、必要とする層間変形角に対応することができる。 According to the load-bearing wall using the corrugated steel sheet having this configuration, since the corrugated steel sheet 7 is stretched on the panel frame 1, when the in-plane shearing force is applied, the wave crest of the corrugated steel sheet 7 has a ridge line. By distorting in a direction substantially perpendicular to the direction, stable energy absorption without slip property is performed with respect to the in-plane shear force. Although there is a limit on the width of the corrugated steel sheet that can stably absorb energy, the divided corrugated steel sheets 7A that are lined up and down are divided by slits 8 that are perpendicular to the mountain ridge line direction. Further, the corrugated steel plate portions 7Aa and 7Aa on both sides are interrupted or reduced in transmission of load. Further, the corrugated steel sheet exhibits the energy absorption function by being fixed at the wave trough, but the corrugated steel sheet portions 7Aa and 7Aa have sides that serve as load transmission separating portions by the slits 8. It is fixed to the vertical beam 5 which is the middle beam, and the other sides are fixed to the horizontal beam 4 and the vertical frame member 2, so that the corrugated steel plate portions 7Aa and 7Aa can be independently deformed. The energy absorption effect by is obtained. Therefore, by setting the width of the corrugated steel sheet portions 7Aa and 7Aa on both sides to be less than the limit width, even if the entire width of the load bearing wall is wide, it is necessary without changing the bent shape of the corrugated steel sheet. It is possible to cope with the interlayer deformation angle. In this example, the width of the corrugated steel sheet portions 7Aa and 7Aa is divided into half of the width of 375 mm with respect to the panel width of 750 mm. If the corrugated steel sheet portion width of 375 mm is equal to or less than the limit width, it is necessary. It is possible to cope with the interlayer deformation angle.
　また、この実施形態ではスリット８によって荷重伝達分離部を構成しているため、次の利点が得られる。すなわち、波型鋼板を完全に分離された複数枚に分けた場合、波型鋼板をフレーム材に取付ける際に位置合わせが複雑になる。また、複数枚製造するため、同一面積当たりの工数が増え、製造コストが増加する。しかし、上記のように荷重伝達分離部をスリット８とした場合、荷重伝達分離部で分離されていない１枚の大きな波型鋼板を使用できる。ここでは、横幅方向については１枚の分割波型鋼板７Ａとしている。そのため、分割波型鋼板７Ａをさらに荷重伝達分離部で分割して２枚の独立した波型鋼板部分７Ａａ，７Ａａとする場合と異なり、荷重伝達分離部の両側の波型鋼板部分７Ａａ，７Ａａを相互に位置合わせする工程が不要であり、位置合わせ工程の増加によるコトス増が解消できる。スリット８の加工は必要であるが、前記位置合わせに比べて簡単な工程で済む。 Further, in this embodiment, since the load transmission separating portion is constituted by the slit 8, the following advantages can be obtained. That is, when the corrugated steel sheet is divided into a plurality of completely separated sheets, the positioning becomes complicated when the corrugated steel sheet is attached to the frame material. In addition, since a plurality of sheets are manufactured, the number of steps per the same area increases and the manufacturing cost increases. However, when the load transmission separation portion is the slit 8 as described above, one large corrugated steel sheet that is not separated by the load transmission separation portion can be used. Here, it is set as the one split-wave type steel plate 7A about a horizontal width direction. Therefore, unlike the case where the divided corrugated steel sheet 7A is further divided by the load transmission separating portion into two independent corrugated steel sheet portions 7Aa, 7Aa, the corrugated steel sheet portions 7Aa, 7Aa on both sides of the load transmitting separating portion are A process of aligning each other is not necessary, and an increase in cost due to an increase in the aligning process can be eliminated. Processing of the slit 8 is necessary, but a simple process is sufficient as compared with the alignment.
　前記分割波型鋼板７Ａは、波の山部７ａの頂部および谷部７ｂの底部が平坦部分となる断面矩形または台形の波形であるが、前記スリット８は、前記谷部７ｂの底部となる平坦部分を除く全範囲に渡って設けている。このように、スリット８を波の谷部７ｂの底部となる平坦部分を除く全範囲に渡って設けることで、スリット８が長くなり、スリット８の両側の部分間での荷重の伝達がより生じ難くなる。そのため、スリット８の両側の部分を相互に独立させてエネルギー吸収を行わせる機能が増大し、より安定してエネルギー吸収能力が確保できる。また、スリット８の幅は５mm以上としているが、５mm以上であると、変形時においてスリット８で分離される山部間での干渉が無く、この点からも安定したエネルギー吸収能力を確保することができる。 The split corrugated steel sheet 7A has a rectangular or trapezoidal waveform with the top of the wave crest 7a and the bottom of the trough 7b being flat, but the slit 8 is flat to be the bottom of the trough 7b. It is provided over the entire range excluding the part. Thus, by providing the slit 8 over the entire range excluding the flat portion that becomes the bottom of the wave trough portion 7b, the slit 8 becomes longer, and more load is transmitted between the portions on both sides of the slit 8. It becomes difficult. For this reason, the function of absorbing energy by making the portions on both sides of the slit 8 independent from each other increases, and the energy absorption capability can be secured more stably. Moreover, the width of the slit 8 is 5 mm or more, but if it is 5 mm or more, there is no interference between the peaks separated by the slit 8 at the time of deformation, and also from this point, a stable energy absorption capability is ensured. Can do.
　なお、波型鋼板７，分割波型鋼板７Ａの山部７ａにのみスリット８を設けるには、予め波型鋼板となる素材鋼板の所定の位置にスリット８を設け、その後そのスリット形成済み鋼板を折り曲げて波板形状にすれば良い。また、素材鋼板を波型鋼板７，分割波型鋼板７Ａに折り曲げ加工する方法としては、ベンダーによる曲げ加工や、金型によりプレス成形する方法、およびロール成形する方法がある。これらのいずれの方法も、山部７ａにのみスリット８を設けた波型鋼板７，分割波型鋼板７Ａの形成に対応できる。また、プレス成形による方法では、スリット８を設ける位置で素材鋼板を打ち抜く形状とした金型を用いれば、一度の加工でスリット８の形成と素材鋼板の折り曲げ加工を行うことができる。 In addition, in order to provide the slit 8 only in the peak portion 7a of the corrugated steel sheet 7 and the split corrugated steel sheet 7A, the slit 8 is previously provided at a predetermined position of the material steel sheet to be the corrugated steel sheet, and then the slit-formed steel sheet is It may be bent into a corrugated plate shape. In addition, as a method of bending the raw steel plate into the corrugated steel plate 7 and the split corrugated steel plate 7A, there are a bending process by a bender, a press molding process using a mold, and a roll molding process. Any of these methods can cope with the formation of the corrugated steel sheet 7 and the split corrugated steel sheet 7A provided with the slits 8 only in the peak portion 7a. Further, in the method by press forming, if a die having a shape in which the material steel plate is punched out at a position where the slit 8 is provided, the slit 8 can be formed and the material steel plate can be bent by a single process.
　また、この実施形態では、波型鋼板７を上下に並ぶ４枚の分割波型鋼板７Ａに分割しているが、このため、パネル高さ３０００mmに対して全上下幅に続く長い波型鋼板を用いることなく、４分割された上下幅７５０mmの波型鋼板を材料して用いれば良く、波型鋼板の入手や取扱性が容易であり、これによっても安価となる。すなわち、波型鋼板７の山部稜線方向が横方向である場合、安定したエネルギー吸収の観点からは、波型鋼板７を上下方向に複数枚に分割する必要はないが、１枚の長すぎる波型鋼板は却って取扱性や加工性が悪く、適度の長さに分割することで、取扱性，加工性，入手性が向上し、安価となる。 Further, in this embodiment, the corrugated steel sheet 7 is divided into four divided corrugated steel sheets 7A arranged vertically. For this reason, a long corrugated steel sheet that continues to the full vertical width with respect to the panel height of 3000 mm is provided. The corrugated steel sheet having a vertical width of 750 mm divided into four parts may be used without being used, and the corrugated steel sheet can be easily obtained and handled, thereby reducing the cost. That is, when the ridge line direction of the corrugated steel sheet 7 is a lateral direction, it is not necessary to divide the corrugated steel sheet 7 into a plurality of sheets in the vertical direction from the viewpoint of stable energy absorption, but one sheet is too long. On the other hand, corrugated steel sheets are poor in handleability and workability. By dividing into corrugated lengths, the handleability, workability, and availability are improved and the cost is reduced.
　このように、耐力壁の全体の幅寸法や高さ寸法が前記限界幅を超える寸法である場合であっても、波型鋼板の折り曲げ形状を変えずに、スリップ性状のない安定したエネルギー吸収能力を確保することができる。しかも、上記のように限界幅を超えても安定したエネルギー吸収能力を確保しながら、加工工数が少なくて済み、製造コストの増加を抑えることができる。 In this way, even if the overall width and height of the load bearing wall are larger than the limit width, the stable energy absorption capacity without slipping properties is maintained without changing the bent shape of the corrugated steel sheet. Can be secured. Moreover, even if the limit width is exceeded as described above, it is possible to reduce the number of processing steps while securing a stable energy absorption capability, and it is possible to suppress an increase in manufacturing cost.
　図５は、この発明の他の実施形態を示す。この波型鋼板使用の耐力壁では、図１～図４Ｂに示す実施形態において、各分割波型鋼板７Ａを左右に分ける荷重伝達分離部として、前記スリット８を設けた構成に変えて、荷重の伝達を遮断する分割部９が縦桟５に沿って設けられている。すなわち、左右の波型鋼板部分７ＡＡ，７ＡＡを分割部９で互いに完全に別個の板としている。なお、図５でも、波型鋼板７の断面形状と、各部材の寸法とが併せて示されている。その他の構成は図１～図４Ｂに示した実施形態の場合と同様である。 FIG. 5 shows another embodiment of the present invention. In the load bearing wall using the corrugated steel sheet, in the embodiment shown in FIGS. 1 to 4B, instead of the configuration in which the slit 8 is provided as a load transmission separating portion that divides each divided corrugated steel sheet 7A into left and right, A dividing portion 9 for interrupting transmission is provided along the vertical rail 5. That is, the left and right corrugated steel plate portions 7AA and 7AA are separated from each other by the dividing portion 9. FIG. 5 also shows the cross-sectional shape of the corrugated steel sheet 7 and the dimensions of each member. Other configurations are the same as those of the embodiment shown in FIGS. 1 to 4B.
　この実施形態の場合も、波型鋼板７の分割波型鋼板７Ａにおける分割部９で分割された左右の波型鋼板部分７ＡＡ，７ＡＡの幅を、安定したエネルギー吸収能力を確保するための限界幅以下に設定して、必要とする層間変形角に対応することができる。そのため、パネル幅の全体に渡る１枚の波型鋼板ないしは分割波型鋼板を張る場合に比べて、大変形に容易に追従できる。これにより、耐力壁の横幅寸法が安定したエネルギー吸収能力を確保するための波型鋼板の限界幅を超えても、波型鋼板の折り曲げ形状を考慮することなく、スリップ性状のない安定したエネルギー吸収能力を確保することができる。 Also in this embodiment, the width of the left and right corrugated steel sheet portions 7AA, 7AA divided by the dividing portion 9 in the split corrugated steel sheet 7A of the corrugated steel sheet 7 is the limit width for ensuring stable energy absorption capability. It can be set as follows to cope with the required interlayer deformation angle. Therefore, large deformation can be easily followed as compared with the case where one corrugated steel sheet or split corrugated steel sheet is stretched over the entire panel width. As a result, even if the width dimension of the bearing wall exceeds the limit width of the corrugated steel sheet to ensure stable energy absorption capacity, stable energy absorption without slipping properties is taken into consideration without considering the bent shape of the corrugated steel sheet. Capability can be secured.
　図６および図７は、この発明のさらに他の実施形態を示す。この波型鋼板使用の耐力壁では、図７のように、左右のフレーム材２，２と上下のフレーム材３，３とで構成される矩形のパネルフレーム１の壁面区画６内に、横方向に延びる中桟となる横桟４が、壁面区画６を上下に並ぶ複数（図示の例では６つ）の分割区画６Ｂに等分するように上下に等間隔に複数本（図示の例では５本）設けられる。縦桟は設けられない。 6 and 7 show still another embodiment of the present invention. In the load-bearing wall using the corrugated steel sheet, as shown in FIG. 7, the lateral wall is formed in the wall section 6 of the rectangular panel frame 1 composed of the left and right frame members 2 and 2 and the upper and lower frame members 3 and 3. A plurality of horizontal rails 4 that are middle rails extending in the vertical direction are equally spaced vertically (5 in the example shown in the figure) so as to equally divide the wall section 6 into a plurality of (six in the example shown in the figure) divided sections 6B. Book). There are no vertical bars.
　図６に正面図で示すように、波型鋼板７は、一方向に延びる山部７ａと谷部７ｂとが交互に並ぶ断面波形の鋼板であり、ここでは波の山部稜線方向が縦方向に向くように前記壁面区画６に張られている。波型鋼板７の波形は、図１～図４Ｂの実施形態の場合と同様に、波山となる山部７ａの頂部および波谷となる谷部７ｂの底部が平坦部分となる断面矩形または台形である。なお、図６でも、波型鋼板７の断面形状と、各部材の寸法とが併せて示されている。 As shown in the front view of FIG. 6, the corrugated steel sheet 7 is a corrugated steel sheet in which crests 7a and troughs 7b extending in one direction are alternately arranged. Here, the crest ridge line direction is the vertical direction. The wall surface section 6 is stretched so as to face. The waveform of the corrugated steel sheet 7 is a rectangular or trapezoidal cross section in which the top of the crest 7a serving as the wavy peak and the bottom of the trough 7b serving as the wave trough are flat portions, as in the embodiment of FIGS. 1 to 4B. . 6 also shows the cross-sectional shape of the corrugated steel sheet 7 and the dimensions of each member.
　この場合の波型鋼板７は、山部稜線方向と直交する横方向に設けられて荷重の伝達を遮断する荷重伝達分離部である分割部９によって、互いに分割された上下６枚の分割波型鋼板７Ｂの集合体として構成され、１枚ごとの分割波型鋼板７Ｂが、前記壁面区画６を前記横桟４で等分した各分割区画６Ｂにそれぞれ張られる。ここでは、荷重伝達分離部となるスリットは設けられていない。各分割波型鋼板７Ｂは、それらの波の谷部７ｂで前記フレーム材２，３および横桟４にボルト１０を用いて固定されている。その他の構成は図１～図４Ｂの実施形態の場合と同様である。 In this case, the corrugated steel sheet 7 is divided into six upper and lower divided corrugations divided by a dividing portion 9 which is provided in a lateral direction perpendicular to the ridge line direction and blocks load transmission. Each of the divided wave type steel plates 7B is configured as an aggregate of the steel plates 7B, and is stretched on each divided section 6B obtained by equally dividing the wall surface section 6 by the cross rails 4. Here, no slit serving as a load transmission separating portion is provided. Each of the split corrugated steel plates 7B is fixed to the frame members 2 and 3 and the cross rails 4 with bolts 10 at valley portions 7b of the waves. Other configurations are the same as those of the embodiment of FIGS. 1 to 4B.
　この実施形態では、波型鋼板７を山部稜線方向と直交する横方向の分割部９によって上下６枚の分割波型鋼板７Ｂに分割しているので、上下幅につき、安定したエネルギー吸収能力を確保するための限界幅を超えない分割波型鋼板７Ｂとできる。これにより、耐力壁の高さ幅が、１枚の波型鋼板では安定したエネルギー吸収能力を確保できる限界幅を超えても、波型鋼板の折り曲げ形状を考慮することなく、スリップ性状のない安定したエネルギー吸収能力を確保することができる。 In this embodiment, the corrugated steel sheet 7 is divided into six upper and lower divided corrugated steel sheets 7B by the laterally dividing section 9 orthogonal to the ridge line direction. It can be set as the division wave type steel plate 7B which does not exceed the limit width for ensuring. As a result, even if the height width of the load-bearing wall exceeds the limit width that can secure a stable energy absorption capacity with one corrugated steel sheet, it is stable without slip properties without considering the bent shape of the corrugated steel sheet. Energy absorption capability.
　図８～図９Ｂは、この発明のさらに他の実施形態を示す。この波型鋼板使用の耐力壁では、図６および図７の実施形態において、荷重の伝達を遮断する荷重伝達分離部となる上下に並ぶ５つの分割部９のうち、一つ置きとなる１段目，３段目、および５段目の分割部９を、図１～図４Ｂの実施形態における荷重の伝達を低下させる荷重伝達分離部となるスリット８に置き換えている。すなわち、図８に正面図で示すように、壁面区画６の全体に対応する１枚の波型鋼板７に対して、山部稜線方向と直交する分割部９とスリット８とを上下に交互に並べて設けている。これにより、波型鋼板７は、上下に並ぶ３枚の分割波型鋼板７Ｃに分割され、その各分割波型鋼板７Ｃは前記スリット８により上下の波型鋼板部分７Ｃａ，７Ｃａに分離されている。図９Ａ，図９Ｂは、それぞれ図８のIX部を拡大した正面図とその断面図とを示す。なお、図８でも、波型鋼板７の波型断面形状と、各部材の寸法とが併せて示されている。 8 to 9B show still another embodiment of the present invention. In the load-bearing wall using corrugated steel sheets, in the embodiment shown in FIGS. 6 and 7, one of the five divided parts 9 arranged in the vertical direction serving as a load transmission separating part that interrupts the transmission of the load is provided as one stage. The dividing parts 9 in the third, fifth, and fifth stages are replaced with slits 8 serving as load transmission separating parts that reduce load transmission in the embodiment of FIGS. 1 to 4B. That is, as shown in a front view in FIG. 8, with respect to one corrugated steel sheet 7 corresponding to the entire wall section 6, the divided portions 9 and the slits 8 perpendicular to the ridge line direction are alternately turned up and down. It is provided side by side. As a result, the corrugated steel sheet 7 is divided into three divided corrugated steel sheets 7C arranged vertically, and each of the split corrugated steel sheets 7C is separated into upper and lower corrugated steel sheet portions 7Ca and 7Ca by the slits 8. . 9A and 9B show an enlarged front view and a cross-sectional view of the portion IX in FIG. 8, respectively. FIG. 8 also shows the corrugated cross-sectional shape of the corrugated steel sheet 7 and the dimensions of each member.
　この実施形態では、波型鋼板７を、山部稜線方向と直交する横方向の分割部９によって上下３枚の分割波型鋼板７Ｃに分割し、さらに、各分割波型鋼板７Ｃでは、その上下方向の中間位置に山部稜線方向と直交する横方向に沿ってスリット８を設け、各分割波型鋼板７Ｃを上下の波型鋼板部分７Ｃａ，７Ｃａに分離している。そのため、スリット８または分割部９で分けられる上下幅が限界幅を超えない幅であれば、安定したエネルギー吸収能力を確保することができる。また、波型鋼板７が上下３枚の分割波型鋼板７Ｃに分割されているため、１枚の大きな波型鋼板７を張る場合に比べて、作業する分割波型鋼板７Ｃの上下幅で適度の大きさとなって取扱性が良い。 In this embodiment, the corrugated steel sheet 7 is divided into three upper and lower divided corrugated steel sheets 7C by a lateral dividing section 9 orthogonal to the mountain ridge line direction. A slit 8 is provided at a middle position in the direction along the lateral direction perpendicular to the ridge line direction, and each divided corrugated steel sheet 7C is separated into upper and lower corrugated steel sheet portions 7Ca and 7Ca. Therefore, if the vertical width divided by the slit 8 or the dividing portion 9 is a width that does not exceed the limit width, a stable energy absorption capability can be ensured. In addition, since the corrugated steel sheet 7 is divided into three upper and lower divided corrugated steel sheets 7C, the upper and lower widths of the split corrugated steel sheet 7C to be worked are moderate compared to the case where one large corrugated steel sheet 7 is stretched. Easy to handle.
　なお、上記各実施形態では、パネルフレーム１で囲まれる壁面区画６に、波の山部７ａが横方向または縦方向のいずれか１方向に延びる波型鋼板７（分割波型鋼板７Ａ，７Ｂ，７Ｃ）を張った構成のものを例示した。しかし、この発明は、このような構成例に限らず、例えばパネルフレーム１で囲まれる壁面区画６に、波の山部が横方向に延びる分割波型鋼板と縦方向に延びる分割波型鋼板とを複合させて張った構成の場合に適用しても、上記と同様の効果を奏することができる。 In each of the above embodiments, the corrugated steel plate 7 (divided corrugated steel plates 7A, 7B, 7C) is illustrated as an example. However, the present invention is not limited to such a configuration example. For example, in the wall surface section 6 surrounded by the panel frame 1, a split corrugated steel sheet in which a wave crest extends in the lateral direction and a split corrugated steel sheet in the longitudinal direction. Even if it is applied in the case of a configuration in which the two are combined and stretched, the same effect as described above can be obtained.
