Description

この発明は、建築物の外壁等として用いられる面材・ブレース併用耐力壁に関する。     The present invention relates to a bearing material / brace combined bearing wall used as an outer wall of a building.

低層建築物の耐力壁では、耐力要素として引張り型耐力ブレースを用いることが多い。例えば、柱・梁接合部はピン接合とし、地震等による水平力に対しては、柱間に配置される外壁パネルにおいて、引張り力のみ負担するブレースで負担する構造形式(パネル併用軸組構造)である。
引張り型耐力ブレースは、比較的軽量な鋼材を用いて安価に生産できる特長を持つ一方、荷重・変形履歴(復元力特性)は、「スリップ型」の特性を示す。スリップ型の欠点としては、次の点が挙げられる。
・大地震の際、ブレースが塑性化して伸びた後、地震による揺れ戻しの力が作用したとき、伸びた分だけブレースが水平力に全く抵抗しない。
・そのため、揺れ戻し時には、建物が逆方向の水平力に対してブレースで抵抗するまで、何の抵抗力も持たないままで水平に動くことになり、ブレースが抵抗し出すときに衝撃を生じる。このことは、住人が建物に対する不安や不満を持つ一要因となり得る。
In a load bearing wall of a low-rise building, a tensile load-bearing brace is often used as a load bearing element. For example, the column / beam joint is a pin joint, and for horizontal forces due to earthquakes, etc., the outer wall panel placed between the columns is supported by a brace that bears only the tensile force (panel combined frame structure) It is.
Tensile type strength braces have the advantage that they can be produced at low cost using relatively light steel materials, while the load / deformation history (restoring force characteristics) exhibits “slip type” characteristics. The following points can be cited as slip-type defects.
・ In the event of a large earthquake, after the brace is plasticized and stretched, when the trembling force of the earthquake acts, the brace does not resist the horizontal force at all.
-Therefore, when swinging back, the building will move horizontally without any resistance until the building resists against the horizontal force in the opposite direction, causing an impact when the brace begins to resist. This can be a factor for residents to have anxiety and dissatisfaction with the building.

図11は、スリップ型の挙動履歴を示す代表的な例であり、ピン接合の縦フレーム材101、横フレーム材102の間に引張り力のみを示すブレース103を入れた耐力壁100である。前記縦フレーム材101および横フレーム材102は、例えば、それぞれ柱、梁である。水平荷重Pによる押しの時はブレース103が抵抗するが、引き戻し時にブレース103が何の抵抗もしない。図12に完全スリップ型履歴の耐力壁における、繰り返荷重作用時の変形−荷重グラフを示す。変形δを戻す向きに力を掛けたとき、ブレースが力を負担しないので、滑るように変形(スリップ)する。   FIG. 11 is a typical example showing a slip-type behavior history, and is a load bearing wall 100 in which a brace 103 showing only a tensile force is inserted between a pin-joint vertical frame material 101 and a horizontal frame material 102. The vertical frame material 101 and the horizontal frame material 102 are, for example, columns and beams, respectively. The brace 103 resists when pushed by the horizontal load P, but the brace 103 does not resist anything when pulled back. FIG. 12 shows a deformation-load graph in the case of repeated load action in the load-bearing wall of a complete slip type hysteresis. When a force is applied in a direction to return the deformation δ, the brace does not bear the force, so that it deforms (slips) to slide.

これらの問題を解決する為には、「紡錘型」の履歴を持つラーメン架構が一般的には有効である。ただし、ラーメン架構は、柱・梁を剛接合とするために、厚肉の柱を用いる必要があるので、コストや鋼材量の面では不利となる。圧縮ブレースを用いた耐力壁も紡錘型となるが、圧縮ブレースは一般的に断面寸法が大きくなり、コスト面で不利となる。   In order to solve these problems, a frame structure having a “spindle type” history is generally effective. However, the ramen frame is disadvantageous in terms of cost and the amount of steel because it requires the use of thick-walled columns in order to make the columns and beams rigidly connected. The bearing wall using the compression brace is also a spindle type, but the compression brace generally has a large cross-sectional dimension, which is disadvantageous in terms of cost.

図13は、紡錘型の挙動履歴を示す代表的な例を示す。同図は、圧縮ブレース103A入りの耐力壁100Aである。この例では、引き戻すときにもブレース103Aが水平力に抵抗する。図14は完全紡錘型履歴の耐力壁の繰り返荷重作用時の変形−荷重グラフである。スリップ型に比べ、引き戻しときにもブレース103Aが抵抗するので、より多くのエネルギーを吸収することができる(グラフで囲まれた面積がエネルギー吸収量を示し、この面積が大きい)。   FIG. 13 shows a typical example showing a spindle-type behavior history. This figure shows a load bearing wall 100A containing a compression brace 103A. In this example, the brace 103A resists the horizontal force when it is pulled back. FIG. 14 is a deformation-load graph at the time of repeated load action of a load-bearing wall of a complete spindle type hysteresis. Compared to the slip type, the brace 103A resists even when pulled back, so that more energy can be absorbed (the area surrounded by the graph indicates the amount of energy absorption, and this area is large).

このように、引張り型耐力ブレースは、スリップ型の挙動となってエネルギー吸収力が少なく、揺れ戻し時に衝撃が生じ、またラーメン架構や圧縮ブレース使用の架構は、鋼材使用量やコスト面で不利となる。そのため、鋼材量が少なくて済み、かつ紡錘型の履歴を示す架構の開発が必要となる。   In this way, the tensile-type load-bearing brace has a slip-type behavior and has a low energy absorption capacity, and an impact occurs when swinging back. Become. Therefore, it is necessary to develop a frame that requires a small amount of steel and shows a spindle-type history.

紡錘型履歴を示し、軽量鉄骨等の安価な材料を用いた耐力壁としては、耐力要素に波形鋼板を用いたメンブレン型耐力壁がある(例えば、特許文献1)。
メンブレン型耐力壁は、一例を示すと、図15のように、壁面を複数(4分割または6分割)に区画し、各区画層に折板104を用いている。地震時に、水平力に対しては折板104がエネルギーを吸収する機構となっている。同耐力壁は、実験により適切な条件下では紡錘型に近い挙動を示すことが確認されている。
As a load bearing wall that shows a spindle type history and uses an inexpensive material such as a lightweight steel frame, there is a membrane type load bearing wall that uses a corrugated steel plate as a load bearing element (for example, Patent Document 1).
As an example, the membrane-type bearing wall divides the wall surface into a plurality (four or six) as shown in FIG. 15, and uses a folded plate 104 for each partition layer. In the event of an earthquake, the folded plate 104 has a mechanism for absorbing energy against horizontal force. It has been confirmed by experiments that the bearing wall behaves like a spindle type under appropriate conditions.

特開2010−090650号公報JP 2010-090650 A

耐力要素に折板を用いたメンブレン型耐力壁は、鋼材量が少なくて済み、紡錘型の履歴を示すという点で優れるが、次の課題がある。
・耐力壁の全面に折板104を張るため、設備開口用等の孔を得ることができない。孔を開けることで耐力性能低下が予測される。耐力壁に設備開口用の孔を設けないようにするには、建物のプランが制約される。建築物建築計画においては、やむなくその耐力壁位置に開口部(給・排気用貫通口、採光用開口等)を設けなくてはならないこともある。
・切り欠かれた設備開口部分を、施工現場において同様な折板を増し張りする補強方法が先行技術として提案されているが、その施工の手間、品質保持、施工管理上等の現場省略施工の観点から、採用するには難がある。
・仮に折板104に設備開口用の孔を開けて補強したとしても、その部分の剛性評価方法が確立されていない。
A membrane-type load-bearing wall using a folded plate as a load-bearing element is excellent in that it requires a small amount of steel and exhibits a spindle-type history, but has the following problems.
-Since the folded plate 104 is stretched over the entire surface of the load-bearing wall, holes for opening the equipment cannot be obtained. It is predicted that the yield strength will be lowered by opening the hole. In order not to provide a hole for opening the equipment in the bearing wall, the plan of the building is restricted. In a building construction plan, it may be necessary to provide openings (supply / exhaust through-holes, daylighting openings, etc.) at the bearing wall positions.
・ Reinforcing methods have been proposed in the construction site to reinforce the same folded plate at the construction site where the notched opening of the equipment has been cut. From the point of view, there are difficulties to adopt.
Even if a hole for opening an equipment is formed in the folded plate 104 and reinforced, the rigidity evaluation method for that portion has not been established.

そこで、本出願人は、図16に示すように、メンブレン型耐力壁において、設備開口を設ける部分については、折板を用いるのではなく、ブレース105を耐力要素して組み込んだ構成を提案した(例えば、特願2013−038631号)。しかし、次の点で今一つ満足することができない。
すなわち、ブレース105で構成される区画層と折板104で構成される区画層の剛性が異なるため、縦フレーム材に曲げ応力が発生してしまう。具体的には、図17(A)のように地震が来て水平力Pがかかったときに、同図(B)のように耐力壁の各区画層の剛性が同じであると、各区画層の変形が同じとなり、縦フレーム材101に曲げが入らない。しかし、同図(C)のように、折板104を用いた区画層に対してブレース105を用いた区画層の剛性が高くて曲がり難いと、折板104を用いた区画層とブレース105を用いた区画層との間の部分106で縦フレーム材101に曲げ応力が発生してしまう。
この場合、縦フレーム材101に地震時の負荷(曲げ)応力を考慮した構造計算が必要であり、構造計算が煩雑となる。このため、煩雑な構造計算を必要とせずに、鉛直方向の荷重(圧縮、引張り)のみを受けるようにしたい。この為には、折板104を用いた区画層とブレース105を用いた区画層の剛性(単位変形量当たりの力の大きさ)を合わせる必要がある。
Therefore, as shown in FIG. 16, the applicant of the present invention has proposed a configuration in which a brace 105 is incorporated as a load-bearing element, instead of using a folded plate, for a portion where a facility opening is provided in a membrane-type load-bearing wall ( For example, Japanese Patent Application No. 2013-038631). However, I cannot be satisfied with the following points.
That is, since the partition layer composed of the brace 105 and the partition layer composed of the folded plate 104 have different rigidity, bending stress is generated in the vertical frame member. Specifically, when an earthquake occurs and a horizontal force P is applied as shown in FIG. 17 (A), each partition layer of the bearing wall has the same rigidity as shown in FIG. The deformation of the layers is the same, and the vertical frame member 101 is not bent. However, as shown in FIG. 5C, if the partition layer using the brace 105 is rigid and difficult to bend with respect to the partition layer using the folded plate 104, the partition layer using the folded plate 104 and the brace 105 are separated. Bending stress is generated in the vertical frame member 101 at the portion 106 between the used partition layers.
In this case, the vertical frame member 101 needs to have a structural calculation in consideration of the load (bending) stress at the time of the earthquake, and the structural calculation becomes complicated. For this reason, it is desired to receive only the load in the vertical direction (compression, tension) without requiring complicated structural calculations. For this purpose, it is necessary to match the rigidity (magnitude of force per unit deformation amount) of the partition layer using the folded plate 104 and the partition layer using the brace 105.

この発明の目的は、エネルギー吸収性能に優れながら、鋼材使用量が少なくて済み、また性能低下や施工上の不利を生じることなく開口部分を設けることができ、かつ異なる種類の耐力要素を用いることにより生じる縦フレーム材の腰折れ状の性状を簡易に防止することができる面材・ブレース併用耐力壁を提供することである。   The object of the present invention is to use a different type of load-bearing element, with excellent energy-absorbing performance, and with a small amount of steel material used, and with the ability to provide openings without causing performance degradation or construction disadvantages. It is intended to provide a bearing material / brace combined bearing wall that can easily prevent the folded shape of the vertical frame material caused by the above.

この発明の面材・ブレース併用耐力壁は、左右の縦フレーム材と、これら左右の縦フレーム材の上端間および下端間にそれぞれ接合された上下の横フレーム材と、前記左右の縦フレーム材間に接合された中桟となる横フレーム材とを備え、前記中桟となる横フレーム材を境界として上下に並ぶ複数の区画層に区画され、各区画層に耐力要素が設けられた耐力壁であって、
一部の区画層に設けられた前記耐力要素がこの区画層を覆う面材であり、他の一部の区画層に設けられた前記耐力要素が斜材であり、かつ互いに傾斜方向が異なり一端が互いに近づくように2本設けられ、前記斜材用いられた区画層に、この区画層の変形を吸収するデバイス設けられ、
このデバイスは、前記2本の斜材の互いに近づき側の端部を接合した接合部材を前記横フレーム材と接合する束材により構成され、前記斜材が設けられた区画層は、前記デバイが存在することで、前記面材が設けられた区画層と同様の剛性であることを特徴とする。
The bearing material / brace combined bearing wall according to the present invention includes left and right vertical frame members, upper and lower horizontal frame members joined between upper and lower ends of the left and right vertical frame members, and the left and right vertical frame members. A load-bearing wall which is divided into a plurality of partition layers arranged vertically with the horizontal frame material serving as the middle rail as a boundary, and a load-bearing element is provided in each partition layer. There,
The load-bearing elements provided in some of the partition layers are face materials covering the partition layer, and the load-bearing elements provided in the other part of the partition layers are diagonal materials, and the inclination directions are different from each other. There is provided two closer together, the partition layer slant member is used, the device for absorbing the deformation of the partition layer is provided,
This device, a joining member joined ends of the closer side to each other of the two diagonal members are constituted by bundles member joined with said transverse frame members, the partition layer diagonal member is provided, wherein the device Is present, and has the same rigidity as the partition layer provided with the face material .

この構成の面材・ブレース併用耐力壁によると、上下に並ぶ複数の区画層に分け、一部の区画層の耐力要素を面材としたため、その区画層において、紡錘型に近い履歴を示しエネルギー吸収性能に優れた構成となる。他の一部の区画層における耐力要素は斜材としたため、その区画層に、耐力の低下や施工上の不利を伴うことなく、設備用や採光用等の開口部を設けることができる。斜材を用いた区画層は、そのままでは面材を用いた区画層に比べて剛性が高くなるが、この区画層の変形を吸収するデバイスを設けたため、面材を用いた区画層と同様の剛性となるように調整できる。そのため、耐力要素して面材を用いる区画層と斜材を用いる区画層を併用しながら、異なる種類の耐力要素を用いることにより生じる縦フレーム材の腰折れ状の性状を防止することができる。
また、自身が変形するデバイスによって前記区画層の変形を吸収するため、このデバイスの寸法や形状により、剛性の調整が容易に行える。
According to the bearing wall with brace and brace with this structure, it is divided into a plurality of partition layers lined up and down, and the load bearing elements of some partition layers are used as face materials. The structure has excellent absorption performance. Since the load bearing elements in the other part of the partition layers are diagonal materials, the partition layers can be provided with openings for facilities, daylighting, and the like without lowering the yield strength and disadvantages in construction. The partition layer using diagonal materials is more rigid than the partition layer using face materials as it is, but since a device that absorbs deformation of this partition layer is provided, it is the same as the partition layer using surface materials. Can be adjusted to be rigid. For this reason, it is possible to prevent the waist frame-like properties of the vertical frame material that are generated by using different types of load bearing elements while using both the partition layer using the face material as the load bearing element and the partition layer using the diagonal material.
Further, since the deformation of the partition layer is absorbed by the device that deforms itself, the rigidity can be easily adjusted by the size and shape of the device.

具体的には、前記デバイスが、前記2本の斜材の互いに近づき側の端部を接合した接合部を前記横フレーム材と接合する束材からなるため、水平力に対し、エネルギー吸収は、前記束材の軸方向の曲げ剛性によって行われ、またこの束材を接合した前記横フレーム材の全体の曲げ変形によっても行われる。前記斜材を有する前記区画層の全体の剛性調整は、前記デバイスにおける前記束材の長さ、断面変更、および/または前記横フレーム材の断面変更により行われる。   Specifically, since the device is composed of a bundle material that joins the lateral frame material to the joined portion obtained by joining the end portions of the two diagonal materials close to each other, energy absorption with respect to a horizontal force is: This is performed by the bending rigidity in the axial direction of the bundle material, and also by the entire bending deformation of the horizontal frame material to which the bundle material is joined. The overall rigidity of the partition layer having the diagonal member is adjusted by changing the length of the bundle member in the device, changing the cross section, and / or changing the cross section of the horizontal frame member.

なお、この面材・ブレース併用耐力壁は、壁パネルとして構成されたものであっても、また現場組立されたものであっても良い。壁パネルとして構成されたものである場合、前記縦フレーム材および横フレーム材は、それぞれ建築物の柱,梁となるものであっても、柱,梁とは別に設けられる壁パネル内のフレーム材であっても良い。前記耐力要素とする面材には、波型形鋼板や、スキンパネル、耐力合板等が使用できる。   The bearing material / brace combined bearing wall may be configured as a wall panel or may be assembled on site. When configured as a wall panel, the frame material in the wall panel provided separately from the column and beam, even if the vertical frame material and the horizontal frame material are respectively a column and beam of a building. It may be. A corrugated steel plate, a skin panel, a load bearing plywood, or the like can be used as the face material as the load bearing element.

この発明において、前記束材は角パイプを縦に配置した形状であっても良い。この構成の場合、角パイプを切断して前記束材が構成でき、前記デバイスの製造が簡単である。 In the present invention, the bundle member may have a shape in which square pipes are arranged vertically. In the case of this configuration, the bundle can be formed by cutting a square pipe, and the device is easily manufactured.

この発明において、前記斜材を設けた区画層を、この耐力壁パネルの上端または下端に有し、前記デバイスが、前記上端または下端の横フレーム材に接合され、この上端または下端の横フレーム材と、この耐力壁を設置する建物躯体の梁との間に、前記横フレーム材が変形する寸法以上の隙間を有する構成であっても良い。
この面材・ブレース併用耐力壁が耐力壁パネルとして構成される場合など、この耐力壁パネルの上端または下端の横フレーム材と、建物躯体の梁が例えば上下に近接して設置されることがある。このとき、耐力壁パネルの上端または下端の横フレーム材が変形したときに建物躯体の梁と干渉すると、前記横フレーム材の変形が妨げられ、結果的に剛性が上がってしまうが、前記横フレーム材が変形する寸法以上の隙間を設けることで、変形が妨げられることが防止され、区画層の適切な剛性が保持される。
In the present invention, the diagonal layer is provided with a partition layer at an upper end or a lower end of the load-bearing wall panel, and the device is joined to the upper or lower horizontal frame member. And the structure which has the clearance gap more than the dimension which the said horizontal frame material deform | transforms between the beam of the building frame which installs this bearing wall.
When this bearing material / brace bearing wall is configured as a bearing wall panel, the frame material at the top or bottom of this bearing wall panel and the beam of the building frame may be installed close to each other, for example. . At this time, when the horizontal frame material at the upper end or the lower end of the load-bearing wall panel is deformed, if it interferes with the beam of the building frame, the deformation of the horizontal frame material is hindered, resulting in increased rigidity. By providing a gap larger than the dimension that the material deforms, the deformation is prevented from being hindered, and the appropriate rigidity of the partition layer is maintained.

この発明の面材・ブレース併用耐力壁は、左右の縦フレーム材と、これら左右の縦フレーム材の上端間および下端間にそれぞれ接合された上下の横フレーム材と、前記左右の縦フレーム材間に接合された中桟となる横フレーム材とを備え、前記中桟となる横フレーム材を境界として上下に並ぶ複数の区画層に区画され、各区画層に耐力要素が設けられた耐力壁であって、一部の区画層に設けられた前記耐力要素がこの区画層を覆う面材であり、他の一部の区画層に設けられた前記耐力要素が斜材であり、かつ互いに傾斜方向が異なり一端が互いに近づくように2本設けられ、前記斜材用いられた区画層に、この区画層の変形を吸収するデバイス設けられ

前記耐力要素となる面材7が波板であると、面内せん断力が負荷された場合に、その波形の山部が稜線方向と交差する方向に歪むことにより、前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える。そのため、紡錘型により一層近い履歴を示す。
前記波板の他に、図5に示すように平坦な板材を用いても良い。この場合、例えば前記面材7として、スキンパネルや耐力合板を使用しても良い。
When the face material 7 serving as the load bearing element is a corrugated sheet, when an in-plane shear force is applied, the ridges of the corrugation are distorted in a direction intersecting the ridge line direction. Stable energy absorption without slip property. Therefore, a history closer to the spindle type is shown.
In addition to the corrugated sheet, a flat sheet material may be used as shown in FIG. In this case, for example, a skin panel or a load-bearing plywood may be used as the face material 7.

図1において、斜材8は、角パイプまたはその他の形鋼からなり、個々の区画層bに互いに逆方向に傾斜しかつ互いに一端が近づくように2本設けられている。図1の例では、上端の区画層bの2本の斜材8は、上端が互いの近づき側端とされて、上端の横フレーム材4に前記デバイス9Dを介して接合されている。2本の斜材8の下端は互いの広がり側端とされ、中桟となる横フレーム材6に接合されている。下端の区画層bの2本の斜材8は、下端が互いの近づき側端とされて、下端の横フレーム材5に前記デバイス9Dを介して接合されている。これら2本の斜材8の上端は互いの広がり側端とされ、中桟となる横フレーム材6に接合されている。なお、各区画層bにおいて、2本の斜材8の広がり側端は、縦フレーム材3に接合しても良い。   In FIG. 1, the diagonal member 8 is made of a square pipe or other shape steel, and is provided on each partition layer b so as to incline in opposite directions to each other and to approach one end. In the example of FIG. 1, the two diagonal members 8 of the partition layer b at the upper end are joined to the upper lateral frame member 4 via the device 9 </ b> D, with the upper ends thereof being close to each other. The lower ends of the two diagonal members 8 are the spreading side ends of the two diagonal members 8 and are joined to the horizontal frame member 6 serving as an intermediate rail. The two diagonal members 8 of the partition layer b at the lower end are joined to the horizontal frame member 5 at the lower end via the device 9D, with the lower ends thereof being close to each other. The upper ends of these two diagonal members 8 are the spreading side ends of the two diagonal members 8 and are joined to the horizontal frame member 6 serving as an intermediate rail. In each partition layer b, the spread side ends of the two diagonal members 8 may be joined to the vertical frame member 3.

前記デバイス9Dは、図8,図9に示すように、2本の斜材8,8の互いに近づき側の端部を接合した接合部を前記横フレーム材4(5,6)と接合する束材26により構成される。具体的には、このデバイス9Dは、束材26とこの束材26の下面に溶接した接合部材27とでなり、前記束材26は角パイプを縦に配置した構成とされている。接合部材27は、束材26と同様な角パイプを横に配置して構成される。2本の斜材8,8は、その上端面を前記接合部材27の下面に突き合わせて溶接により前記接合部材27に接合されている。   As shown in FIGS. 8 and 9, the device 9D is a bundle that joins a joined portion obtained by joining the end portions of the two diagonal members 8 and 8 close to each other to the lateral frame member 4 (5, 6). The material 26 is used. Specifically, the device 9D includes a bundle member 26 and a joining member 27 welded to the lower surface of the bundle member 26, and the bundle member 26 has a configuration in which square pipes are arranged vertically. The joining member 27 is configured by horizontally arranging square pipes similar to the bundle material 26. The two diagonal members 8, 8 are joined to the joining member 27 by welding with their upper end faces butted against the lower surface of the joining member 27.

図4は、2枚の面材・ブレース併用耐力壁1,1の隣接部付近の拡大水平断面を、外装材等を施した外壁パネルとして構成した状態で示す。枠体2の屋外側には合板からなる下地材41および空気層42を介して外装面材43が張られ、枠体2内の前記波板からなる面材7を張った箇所にはこの面材7の両面にグラスウール等の断熱材44,45が充填されている。枠体2の屋内側には内装面材46が張られる。2枚の面材・ブレース併用耐力壁1,1の隣合う縦フレーム材3の屋外側および屋内側には、グラスウールボード等からなる柱部断熱面材47が張られている。   FIG. 4 shows an enlarged horizontal cross section in the vicinity of an adjacent portion of the two bearing members and bracing bearing walls 1, 1 in a state of being configured as an outer wall panel provided with an exterior material or the like. An exterior surface material 43 is stretched on the outdoor side of the frame body 2 through a base material 41 made of plywood and an air layer 42, and this surface is placed on the surface of the frame body 2 where the surface material 7 made of the corrugated sheet is stretched. Both surfaces of the material 7 are filled with heat insulating materials 44 and 45 such as glass wool. An interior surface material 46 is stretched on the indoor side of the frame body 2. A column heat insulating surface material 47 made of glass wool board or the like is stretched on the outdoor side and the indoor side of the vertical frame material 3 adjacent to the two face materials / brace combined bearing walls 1 and 1.

この構成の面材・ブレース併用耐力壁1によると、上下に並ぶ複数の区画層a,bに分け、一部の区画層aの耐力要素を面材7としたため、その区画層aにおいて、紡錘型に近い履歴を示しエネルギー吸収性能に優れた構成となる。他の一部の区画層bにおける耐力要素は斜材8としたため、その区画層bに、耐力の低下や施工上の不利を伴うことなく、設備用や採光用等の開口部(図示せず)を設けることができる。斜材8を用いた区画層bは、そのままでは面材7を用いた区画層aに比べて剛性が高くなるが、この区画層bの変形を吸収するデバイス9Dを設けたため、面材7を用いた区画層aと同様の剛性となるように容易に調整できる。そのため、耐力要素して面材7を用いる区画層aと斜材8を用いる区画層bを併用しながら、異なる種類の耐力要素を用いることにより生じる縦フレーム材3の腰折れ状の性状を防止することができる。変形を吸収するデバイス9Dを用いるため、このデバイス9Dによって区画層bの剛性調整ができ、各横フレーム材4〜6や斜材8の強度を変えて構造設計で区画層a,bの剛性の調整を行う場合と異なり、煩雑な構造計算を行うことなく、簡単に剛性が調整できる。
このように、紡錘型に近い履歴を示しエネルギー吸収性能に優れながら、鋼材使用量が少なくて済み、また性能低下や施工上の不利を生じることなく開口部分を設けることができ、かつ異なる種類の耐力要素を用いることにより生じる縦フレーム材3の腰折れ状の性状を簡易に防止することができる。
According to the bearing material / brace combined bearing wall 1 having this configuration, the partitioning layer a is divided into a plurality of partition layers a and b arranged in the vertical direction, and the bearing element of some partitioning layers a is used as the surface member 7. It shows a history close to that of a mold and has an excellent energy absorption performance. Since the load bearing element in the other part of the partition layer b is the diagonal member 8, the partition layer b is not provided with an opening for facilities or lighting (not shown) without lowering the yield strength or disadvantages in construction. ) Can be provided. The partition layer b using the diagonal material 8 is more rigid than the partition layer a using the face material 7 as it is, but since the device 9D that absorbs the deformation of the partition layer b is provided, It can be easily adjusted to have the same rigidity as the partition layer a used. Therefore, while using the partition layer a using the face material 7 as the load bearing element and the partition layer b using the diagonal member 8, the waist frame-like properties of the vertical frame member 3 caused by using different types of load bearing elements are prevented. be able to. Since the device 9D that absorbs deformation is used, the rigidity of the partition layer b can be adjusted by the device 9D, and the rigidity of the partition layers a and b can be changed by structural design by changing the strength of the horizontal frame members 4 to 6 and the diagonal member 8. Unlike the case of adjustment, the rigidity can be easily adjusted without performing complicated structural calculations.
In this way, while showing a history close to that of a spindle type and excellent in energy absorption performance, the amount of steel used can be reduced, an opening can be provided without causing performance degradation and construction disadvantages, and different types of It is possible to easily prevent the waist frame of the vertical frame member 3 caused by using the strength element.

前記デバイス9Dは、上記のように束材26で構成されるため、具体的には次の作用が得られる。水平力に対し、エネルギー吸収はデバイス9Dの束材26の曲げモーメントM1による曲げ変形により主に行われ、また横フレーム材4(5,6)の曲げモーメントM2による曲げ変形によっても行われる。斜材8を設けた区画層bの全体の曲げ剛性は、デバイス9Dの束材26の長さ、断面、の変更、および/または横フレーム材4(5,6)の断面の変更により行う。   Since the device 9D is composed of the bundle material 26 as described above, specifically, the following action is obtained. For the horizontal force, energy absorption is mainly performed by bending deformation due to the bending moment M1 of the bundle member 26 of the device 9D, and also by bending deformation due to the bending moment M2 of the lateral frame member 4 (5, 6). The total bending rigidity of the partition layer b provided with the diagonal member 8 is performed by changing the length and cross section of the bundle member 26 of the device 9D and / or changing the cross section of the lateral frame member 4 (5, 6).

この束材26を有するデバイス9Dを設けた場合の各利点を纏め直して次に示す。
・耐力壁1の区画層bごとの剛性調製を容易に行うことができる。
・水平力エネルギーの吸収を行うことができる。
・耐力壁1内の波形鋼板等からなる面材7による区画層aと斜材8の区画層bの剛性を同じにすることにより、部分的な剛性低下を防ぐことができる。
・耐力壁1の両端部の縦フレーム材3が腰折れの性状とならず、耐力壁1の両端の縦フレーム材3に曲げモーメントが伝達されることを防ぐことができる。
The advantages obtained when the device 9D having the bundle 26 is provided will be summarized below.
-Stiffness adjustment for every division layer b of the bearing wall 1 can be performed easily.
-Absorbs horizontal force energy.
-By making the rigidity of the partition layer a by the face material 7 made of corrugated steel plate or the like in the bearing wall 1 and the partition layer b of the diagonal member 8 the same, a partial decrease in rigidity can be prevented.
The vertical frame member 3 at both ends of the load bearing wall 1 does not have a folding property, and it is possible to prevent a bending moment from being transmitted to the vertical frame member 3 at both ends of the load bearing wall 1.

これら図8,図9の例において、斜材8を設けた区画層bが耐力壁1の最上層または最下層に配置される場合は、デバイス9Dが接合された耐力壁1の上端または下端に位置する横フレーム材4,5と、この耐力壁1を設置する建物躯体の梁30(図8)との間に、前記横フレーム材4,5が変形する寸法以上の隙間dを設けることが必要である。
横フレーム材4,5が変形したときに建物躯体の梁30と干渉すると、前記横フレーム材4,5の変形が妨げられ、結果的に剛性が上がってしまうが、前記横フレーム材4,5が変形する寸法以上の隙間を設けることで、変形が妨げられることが回避され、区画層4bの適切な剛性が保持される。
In the examples of FIGS. 8 and 9, when the partition layer b provided with the diagonal member 8 is disposed on the uppermost layer or the lowermost layer of the load bearing wall 1, the upper end or the lower end of the load bearing wall 1 to which the device 9D is joined Between the horizontal frame members 4 and 5 that are positioned and the beam 30 (FIG. 8) of the building frame in which the load-bearing wall 1 is installed, a gap d that is larger than the dimension by which the horizontal frame members 4 and 5 are deformed is provided. is necessary.
If the horizontal frame members 4 and 5 are deformed and interfere with the beams 30 of the building frame, the deformation of the horizontal frame members 4 and 5 is hindered, resulting in increased rigidity. By providing a gap larger than the dimension that deforms, it is avoided that the deformation is prevented, and the appropriate rigidity of the partition layer 4b is maintained.

図10は、耐力要素として面材7を設けた区画層aと、斜材8を設けた区画層bとの配置、およびデバイス9Dの配置の各例を示している。いずれも、区画層a,bの数は合計で4つとし、面材7を設けた区画層aと斜材8を設けた区画層bとは2箇所ずつとしている。図8(A)は、図1の実施形態の例である。
図8(B)の例は、斜材8を設けた区画層bを中央側の2箇所とし、これらの区画層bでは、いずれも2本の斜材8は上端側が交点側となり、交点の付近にデバイス9Dを配置している。
図8(C)の例は、同図(B)の例と同じく、斜材8を設けた区画層bを中央側の2箇所としているが、中央側2箇所の区画層bにおいて、斜材8の傾斜方向が互いに逆であり、上側の区画層bの斜材8と下側の区画層の斜材8とが一直線上に位置してX形を成すように配置されている。デバイス9Dは、4本の斜材8の交点に配置している。この場合、デバイス9Dは、各区画層b毎に別々に設けるが、一つで2つの区画層bの変形を吸収する構成としても良い。
FIG. 10 shows examples of the arrangement of the partition layer a provided with the face material 7 as the load bearing element, the partition layer b provided with the diagonal material 8, and the arrangement of the device 9D. In any case, the total number of the partition layers a and b is four, and the partition layer a provided with the face material 7 and the partition layer b provided with the diagonal material 8 are provided in two places. FIG. 8A is an example of the embodiment of FIG.
In the example of FIG. 8B, the partition layer b provided with the diagonal material 8 has two locations on the center side, and in these partition layers b, the two diagonal materials 8 both have the upper end side at the intersection side, A device 9D is arranged in the vicinity.
8C, as in the example of FIG. 8B, the partition layer b provided with the diagonal material 8 is set at two locations on the central side. However, in the two partition layers b on the central side, the diagonal material is used. The diagonal directions 8 are opposite to each other, and the diagonal member 8 of the upper partition layer b and the diagonal member 8 of the lower partition layer are arranged in a straight line so as to form an X shape. The device 9D is disposed at the intersection of the four diagonal members 8. In this case, the device 9D is provided separately for each partition layer b, but may be configured to absorb the deformation of the two partition layers b.

図10の例ではいずれも、区画層a,bの合計を4つとしたが、区画層a,bの合計は、例えば3つとしても、また5つとしても良い。また、耐力要素として面材7を設けた区画層aの個数と、斜材8を設けた区画層bの個数は互いに異なっていても良い。例えば、全ての区画層の個数が4つであり、斜材8を設けた区画層bを1箇所として、残り3つを面材7を有する区画層aとしても良い。   In the example of FIG. 10, the total of the partition layers a and b is four, but the total of the partition layers a and b may be three or five, for example. Further, the number of partition layers a provided with the face material 7 as a load bearing element and the number of partition layers b provided with the diagonal material 8 may be different from each other. For example, the number of all the partition layers may be four, the partition layer b provided with the diagonal material 8 may be one place, and the remaining three may be partition layers a having the face material 7.

ただし、一般的な低層の建築物に適用する場合であって、斜材8を区画層bに2本逆傾斜に設ける場合、区画層a,bの合計は4つ以下とすることが好ましい。これは、接合部の隅肉溶接部で有効に応力負担する為に、斜材8の水平面に対する傾斜角度を60°以上とするためである。例えば、面材・ブレース併用耐力壁1の高さが、建築物の1つ階高の高さ(例えば.2700mm程度)、幅が1モジュール(800〜1000mm)である場合、区画層a,bの合計数を7つ以上にすると、斜材8の上記傾斜角度が60°以下となる。   However, when it is applied to a general low-rise building and two diagonal members 8 are provided on the partition layer b in a reverse inclination, the total of the partition layers a and b is preferably four or less. This is because the inclination angle of the diagonal member 8 with respect to the horizontal plane is set to 60 ° or more in order to effectively bear the stress at the fillet weld of the joint. For example, when the height of the bearing material / brace bearing wall 1 is the height of the first floor of the building (for example, about 2700 mm) and the width is 1 module (800 to 1000 mm), the partition layers a and b If the total number is 7 or more, the inclination angle of the diagonal member 8 is 60 ° or less.
