Abstract
Description
本発明は、剛性板耐震壁、特に略同一形状の剛性板及び開口部が入れ替わりに現れるように構成した剛性板耐震壁、及び剛性板耐震壁付きのフレーム機構に関する。 The present invention relates to a rigid plate earthquake resistant wall, and more particularly to a rigid plate earthquake resistant wall configured such that a rigid plate having substantially the same shape and an opening appear alternately, and a frame mechanism with the rigid plate earthquake resistant wall.
例えば柱梁架構の内部空間に構築する耐震壁として、上記内部空間に、複数の縦材及び横材を交差箇所で相互に溶接してなる格子状の部材を取り付け、縦材及び横材で囲まれる各開口部の一部に剛性板材をボルト・ナットなどの固定具で締結し、残りの開口部を採光部としてなるものが知られている（特許文献１）。 For example, as a seismic wall built in the internal space of a column beam frame, a lattice-like member is attached to the internal space by welding a plurality of vertical members and cross members to each other at the intersection, and surrounded by vertical members and cross members. It is known that a rigid plate material is fastened to a part of each opening portion with a fixing tool such as a bolt and a nut, and the remaining opening portion is used as a daylighting portion (Patent Document 1).
また柱梁架構の内部空間に、垂直平面に沿って配置された複数の水平材と、これら水平材により支持された壁体とからなり、この壁体は、市松模様状に配置した複数の矩形の剛性板の各角部を相互に連結してなるものが知られている（特許文献２）。 In addition, a plurality of horizontal members arranged along a vertical plane and a wall supported by these horizontal members in the internal space of the column beam frame, and the wall body is a plurality of rectangles arranged in a checkered pattern. There is known one in which the corners of the rigid plate are connected to each other (Patent Document 2).
既存建物の耐震改修において、補強箇所、搬入経路および作業スペースの確保は当該建物の補強を実現する上で重要な要素である。耐震補強工法は単に力学的に耐震性能を向上させる技術としてあるべきではなく、上記の施工性にも重点を置かなければならない。
特許文献１のものでは、格子状部材を内部空間に搬入することに手間がかかる。
特許文献２の市松形の耐震補強工法はこうした施工性に配慮した工法であり、さまざまな条件の建物の耐震改修に適用される。しかしながら、本工法による鋼板壁の地震時水平耐力は四隅をボルトで固定された鋼板のせん断座屈破壊により決定するため、鋼板の強度を十分に発揮できていない。これは、鋼板の四隅部のみを固定しているためであり、せん断座屈耐力式の座屈係数が小さく見積もられるためである。この問題に対して、鋼板の板厚を増して座屈耐力の向上を図ると、壁体の重量が増し、施工性を著しく低下させてしまう。またボルト本数を増やす、溶接して鋼板を固定する等、これらの対処も施工性を損なうことにつながる。
In seismic retrofitting of existing buildings, securing reinforcement points, carrying-in routes, and work spaces are important factors for realizing the reinforcement of the buildings. The seismic retrofitting method should not be merely a technique for mechanically improving seismic performance, but the above workability must also be emphasized.
In the thing of patent document 1, it takes an effort to carry a lattice-shaped member in internal space.
The checkered seismic reinforcement method of Patent Document 2 is a method that takes such workability into consideration, and is applied to seismic repair of buildings under various conditions. However, the horizontal strength at the time of earthquake of the steel plate wall by this method is determined by the shear buckling failure of the steel plate with the four corners fixed with bolts, so that the strength of the steel plate cannot be fully exhibited. This is because only the four corners of the steel plate are fixed, and the buckling coefficient of the shear buckling strength formula is estimated to be small. In response to this problem, when the thickness of the steel plate is increased to improve the buckling strength, the weight of the wall body increases and the workability is significantly reduced. Moreover, these measures, such as increasing the number of bolts and fixing the steel plate by welding, also lead to the loss of workability.
本発明の目的は、施工性を損なうことなく剛性板耐震壁の補強効果を向上させることである。 The objective of this invention is improving the reinforcement effect of a rigid board earthquake-resistant wall, without impairing workability.

Regarding the description “combining the same shape and same size polygonal rigid plate in a certain pattern”, as the certain pattern, a rectangular rigid plate and a pattern in which openings appear alternately in two directions (see FIG. 1), a triangular rigid plate, and a pattern in which openings appear alternately in three directions (scale pattern shown in FIG. 13).
With regard to “same shape / same size”, a part of the shape of the original rigid plate may be cut off according to the outline of the frame portion at the end of the wall body and the portion to be joined to the frame portion described later. .
The “stiffening rib” can be formed in a loop shape (including a ring shape or a polygonal shape).
第２の手段は、第１の手段を有し、かつ
上記連接する角部同士に連なる、各剛性板の対応する辺部が平行になるように各剛性板を配置し、
補剛リブは、リング状又は多角形状であり、各剛性板の隣り合う角部の固定点を仮想線分で結んでなる多角形の内部領域を通過するように配置した。
The second means includes the first means, and the rigid plates are arranged so that the corresponding side portions of the rigid plates connected to the connecting corners are parallel to each other,
The stiffening rib has a ring shape or a polygonal shape, and is arranged so as to pass through a polygonal internal region formed by connecting fixed points of adjacent corners of each rigid plate with imaginary line segments.
本手段は、補剛リブ３０を、剛性板２２に対して直角な方向から見てリング状（図１参照）又は多角形状（図８参照）に形成することを提案している。図示の多角形は剛性板の輪郭に相似な多角形であるが、非相似な多角形であっても構わない。また補剛リブ３０は、各剛性板の隣り合う角部の固定点を仮想線分で結んでなる多角形の内部領域Ｉを通過するように配置している。これにより少なくとも内部領域Ｉに生ずる座屈変形をより効果的に防止できる。座屈変形を有効に示すために、補剛リブ３０は、内部領域Ｉ内のある程度の大きさ（図４に示す例では内部領域の大半）を占めるようにすることが効果的である。「リング状」又は「多角形状」とは、リング又は多角形の輪郭の一部を省略した欠失形状を含むものとする。 This means proposes that the stiffening rib 30 is formed in a ring shape (see FIG. 1) or a polygonal shape (see FIG. 8) when viewed from a direction perpendicular to the rigid plate 22. The illustrated polygon is a polygon similar to the contour of the rigid plate, but may be a non-similar polygon. Further, the stiffening ribs 30 are arranged so as to pass through a polygonal internal region I formed by connecting fixed points of adjacent corners of each rigid plate with imaginary line segments. Thereby, buckling deformation occurring at least in the inner region I can be more effectively prevented. In order to effectively show the buckling deformation, it is effective that the stiffening rib 30 occupies a certain size in the inner region I (most of the inner region in the example shown in FIG. 4). The “ring shape” or “polygon shape” includes a deletion shape in which a part of the outline of the ring or polygon is omitted.
第３の手段は、第２の手段を有し、かつ

The third means includes the second means, and the wall body is composed of a plurality of rectangular rigid plates arranged in a checkered pattern, and the stiffening rib is rigid within the internal region. It was formed so as to intersect two diagonal lines of the plate.
本手段は、図１に示すように市松模様に組み合わせた４角形の剛性板２２の２本の対角線と、補剛リブ３０とが、内部領域Ｉ内で交差するように形成している。これにより対角線近くに作用する外力に抵抗することができ、座屈変形を阻止する効果が高まる。 This means is formed so that two diagonal lines of a rectangular rigid plate 22 combined in a checkered pattern and a stiffening rib 30 intersect in the inner region I as shown in FIG. Thereby, it is possible to resist the external force acting near the diagonal, and the effect of preventing buckling deformation is enhanced.
第４の手段は、第１の手段から第３の手段のいずれかを有し、かつ
上記仮想平面に沿って平行に並設された複数の格子材を有する支持手段を具備し、
上記各格子材は、壁体と直交する方向からみて、少なくとも２枚の剛性板の連接する角部の組み合わせと重ね合わせるように配置され、

The fourth means includes any of the first means to the third means, and includes a support means having a plurality of lattice members arranged in parallel along the virtual plane,
Each of the lattice members is disposed so as to overlap with a combination of corner portions connected to at least two rigid plates when viewed from a direction orthogonal to the wall body,
The combination of the corners is fixed to the lattice material at the overlapping position.
本手段では、図３に示すように上記壁体２０を支持する格子材１６を含む支持手段１２を設けることを提案している。これにより壁体２０全体の強度を向上させることができる。 In this means, as shown in FIG. 3, it is proposed to provide a support means 12 including a lattice material 16 that supports the wall body 20. Thereby, the intensity | strength of the whole wall body 20 can be improved.
第５の手段は、第１の手段から第４の手段のいずれかを有し、かつ上記補剛リブは剛性板と直角な鋼管であり、当該剛性板に対して溶接している。 The fifth means includes any one of the first means to the fourth means, and the stiffening rib is a steel pipe perpendicular to the rigid plate, and is welded to the rigid plate.
本手段では、例えば図５に示す如く補剛リブ３０を剛性板２２と直角に付設した鋼管として形成することを提案している。補剛リブ３０は、既存の鋼板の一部を切り出すことで得られるものとすることができる。 In this means, for example, as shown in FIG. 5, it is proposed that the stiffening rib 30 is formed as a steel pipe attached to the rigid plate 22 at a right angle. The stiffening rib 30 can be obtained by cutting out a part of an existing steel plate.
第６の手段は、建造物のフレーム部に第１の手段から第５の手段のいずれかに記載の剛性板耐震壁を適用した剛性板耐震壁付きのフレーム機構であって、上記剛性板の一部はフレーム部に隣接しており、隣接箇所をフレーム部に固定している。 A sixth means is a frame mechanism with a rigid plate earthquake resistant wall in which the rigid plate earthquake resistant wall according to any one of the first means to the fifth means is applied to a frame portion of a building, A part is adjacent to the frame portion, and the adjacent portion is fixed to the frame portion.
本手段では、図１に示すフレーム部に隣接する剛性板を、フレーム部２に対して固設している。なお、好適な実施例として、図１５に示すように、フレーム部に隣接した剛性板には補剛リブを設けず、フレーム部に隣接していない剛性板にのみ補剛リブを設けるようにすることができる。これにより、フレーム部２から離れた座屈し易い剛性板２２を補剛するので、効果的に補剛作用を高めることができる。「剛性板をフレーム部に固設する」とは、後述の支持枠の如き介在物を途中に存して介在させて固設することを含む。また、介在物は、フレーム部２の内周辺の四辺に必ずしも設ける必要はなく、適宜な強度と剛性を有する部材であれば、少なくとも一辺はフレーム部２から離れた、その近傍に設ける機構であっても良い。 In this means, a rigid plate adjacent to the frame portion shown in FIG. 1 is fixed to the frame portion 2. As a preferred embodiment, as shown in FIG. 15, the rigid plate adjacent to the frame portion is not provided with the stiffening rib, and only the rigid plate not adjacent to the frame portion is provided with the stiffening rib. be able to. As a result, the rigid plate 22 that is easily buckled away from the frame portion 2 is stiffened, so that the stiffening action can be effectively enhanced. “Fixing the rigid plate to the frame portion” includes fixing by interposing an intervening material such as a support frame described later. In addition, the inclusions are not necessarily provided on the four sides on the inner periphery of the frame part 2, but if the member has an appropriate strength and rigidity, at least one side is a mechanism provided in the vicinity thereof away from the frame part 2. May be.
第１の手段に係る発明によれば、剛性板の補剛リブは、隣りの角部の固定点同士を結ぶ仮想線分の全部に近接し或いは交接するように形成したから、当該剛性板の座屈変形を効果的に防止することができる。これにより耐震壁を構成するために必要な固定具（ボルトなど）の個数数を削減することができ、比較的簡単に施工できる。また補剛リブで補強するから、所定の補剛効果を得るために要する剛性板の厚みを小とすることができる。
第２の手段に係る発明によれば、補剛リブは、各剛性板の連接する角部同士の固定点を仮想線分で結んでなる多角形に形成される内部領域を通過するから、座屈変形に対する抵抗力が向上する。
第３の手段に係る発明によれば、上記壁体は、市松模様に配置された複数の４角形の剛性板で構成したから、剛性板耐震壁を軽量化することができ、この剛性板の２本の対角線と交差するように補剛リブを形成したから、剛性板の座屈をより的確に防止できる。
第４の手段に係る発明によれば、隣接する剛性板の連接する角部の組み合わせを格子材に重ねて固定したから、剛性板耐震壁の強度が向上する。
第５の手段に係る発明によれば、補剛リブを剛性板と直角な鋼管であり、既成の鋼管から切り出して剛性板に溶接すればよいから、簡易に製作することができ、またボルトの使用本数を増やすことなく補剛性能を向上することができる。
第６の手段に係る発明によれば、建造物のフレーム部に剛性板耐震壁を適用したからフレーム部を簡易に補強することができる。
According to the invention relating to the first means, the stiffening ribs of the rigid plate are formed so as to be close to or intersecting with all of the imaginary line segment connecting the fixed points of the adjacent corners. Buckling deformation can be effectively prevented. As a result, the number of fixtures (bolts and the like) necessary for constructing the earthquake-resistant wall can be reduced, and construction can be performed relatively easily. Further, since the reinforcing ribs are used for reinforcement, the thickness of the rigid plate required for obtaining a predetermined stiffening effect can be reduced.
According to the second aspect of the invention, the stiffening rib passes through the internal region formed in a polygon formed by connecting the fixed points of the connecting corners of each rigid plate with imaginary line segments. Resistance to bending deformation is improved.
According to the invention relating to the third means, since the wall body is composed of a plurality of rectangular rigid plates arranged in a checkered pattern, the rigid plate earthquake-resistant wall can be reduced in weight. Since the stiffening rib is formed so as to intersect the two diagonal lines, buckling of the rigid plate can be prevented more accurately.
According to the fourth aspect of the invention, since the combination of corner portions of adjacent rigid plates connected to each other is fixed on the lattice material, the strength of the rigid plate earthquake resistant wall is improved.
According to the fifth aspect of the invention, the stiffening rib is a steel pipe perpendicular to the rigid plate, and it can be easily manufactured because it can be cut out from the existing steel pipe and welded to the rigid plate. It is possible to improve the supplementary rigidity ability without increasing the number used.
According to the invention relating to the sixth means, since the rigid plate earthquake resistant wall is applied to the frame portion of the building, the frame portion can be easily reinforced.
図１から図７は、本発明の第１の実施形態に係る剛性板耐震壁１０を示している。この剛性板耐震壁は、建造物のフレーム部２の内周面４内に設置されている。このフレーム部は、本実施形態では柱２ａ及び梁２ｂからなる柱梁構造としている。なお、図１中、６は梁２ｂとは異なる方向の梁、８は床スラブである。 1 to 7 show a rigid plate earthquake-resistant wall 10 according to the first embodiment of the present invention. This rigid plate earthquake resistant wall is installed in the inner peripheral surface 4 of the frame part 2 of the building. In this embodiment, the frame portion has a column beam structure including columns 2a and beams 2b. In FIG. 1, 6 is a beam in a direction different from that of the beam 2b, and 8 is a floor slab.
剛性板耐震壁１０は、本実施形態では、支持手段１２と壁体２０とで構成される。しかしながら、図７に示す如く、支持手段を省略しても構わない。 In this embodiment, the rigid plate earthquake-resistant wall 10 is composed of a support means 12 and a wall body 20. However, the support means may be omitted as shown in FIG.
上記支持手段１２は、上記壁体２０をフレーム部２内に支持するための手段であり、少なくともフレーム部２の内周面４の対向する２辺の間に架設する複数の格子材１６を具備する。 The support means 12 is a means for supporting the wall body 20 in the frame portion 2, and includes a plurality of lattice members 16 constructed at least between two opposing sides of the inner peripheral surface 4 of the frame portion 2. To do.
本実施形態の支持手段１２は、内周面４内に取り付けた支持枠１４を含み、この支持枠１４を介して格子材１６を設けている。しかしながらその構造は適宜変更することができ、フレーム部である柱又は梁に格子材１６を直接連結しても構わない。上記支持枠１４は、縦枠１４ａ及び横枠１４ｂで構成される。図示の縦枠及び横枠は断面Ｌ字型の鋼材で形成され、そのＬ字の一方板部（ウェブ）を接着剤Ｊでフレーム部２内面に接着するともに他方板部（フランジ部）に剛性板取付け用の取り付け孔１５を穿設している。 The support means 12 of this embodiment includes a support frame 14 attached in the inner peripheral surface 4, and a lattice material 16 is provided via the support frame 14. However, the structure can be changed as appropriate, and the lattice material 16 may be directly connected to the pillar or beam as the frame portion. The support frame 14 includes a vertical frame 14a and a horizontal frame 14b. The illustrated vertical frame and horizontal frame are formed of steel material having an L-shaped cross section, and one L-shaped plate (web) is bonded to the inner surface of the frame 2 with an adhesive J and the other plate (flange) is rigid. A mounting hole 15 for mounting the plate is formed.
上記支持枠１４はフレーム部２と後述の壁体の剛性板との間の介在物として壁体を支える機能を有する。もっとも当該介在物は、フレーム部２の内周辺の四辺に必ずしも設ける必要はなく、適宜な強度と剛性を有する部材であれば、少なくとも一辺はフレーム部２から離れた、その近傍に設ける機構であっても良い。例えば図１に示すフレーム部に隣接する剛性板のうち、右端部の剛性板の上下２枚分を省略した上で、省略後に生じた右側の端部に位置する格子材１６を支持枠１４に替えてフレーム部２に連結することでも好適に実施できる。 The support frame 14 has a function of supporting the wall body as an inclusion between the frame portion 2 and a rigid plate of the wall body described later. Of course, the inclusions are not necessarily provided on the four sides of the inner periphery of the frame part 2, but if the member has appropriate strength and rigidity, at least one side is a mechanism provided in the vicinity thereof away from the frame part 2. May be. For example, among the rigid plates adjacent to the frame portion shown in FIG. 1, the upper and lower two rigid plates at the right end portion are omitted, and the lattice material 16 positioned at the right end portion after the omission is attached to the support frame 14. It can implement suitably also by connecting to the frame part 2 instead.
複数の格子材１６は、本実施形態では一定の間隔を存して並設しているが、必要があれば間隔を変更しても構わない。格子材１６は、後述の四角形状の剛性板２２の２つの辺部Ｓの何れかの方向（図示例では垂直方向又は水平方向）に一致させ、開口部４０を遮ることのないように設置することが好適である。しかしながら、この構造に限定されるものではない。格子材１６の両端部１６ａは、支持枠１４の横枠１４ｂに対して適当な手段で固定する。固定手段としては、図示はしないが、溶接やボルト留めなどの従来公知の方法を用いればよい。格子材１６は、後述の剛性板２２を支持するためのものであり、図示例では、剛性板を固定するための複数の第１留め孔１８を好ましくは等間隔で設けている。 In the present embodiment, the plurality of lattice members 16 are arranged side by side with a constant interval, but the interval may be changed if necessary. The lattice material 16 is arranged so as to coincide with any direction (vertical direction or horizontal direction in the illustrated example) of two side portions S of a rectangular rigid plate 22 to be described later so as not to block the opening 40. Is preferred. However, it is not limited to this structure. Both end portions 16a of the lattice material 16 are fixed to the horizontal frame 14b of the support frame 14 by appropriate means. As the fixing means, although not shown, a conventionally known method such as welding or bolting may be used. The lattice material 16 is for supporting a rigid plate 22 which will be described later. In the illustrated example, a plurality of first retaining holes 18 for fixing the rigid plate are preferably provided at equal intervals.
壁体２０は、相互の間に開口部４０を存して開口部と相互に入れ替わるように配列された複数の剛性板２２と、剛性板２２に付設された補剛リブ３０とからなる。壁体２０の外周部に位置する剛性板部分は上記支持枠１４に対して固設する。これについては後述する。図示例の壁体２０は、４角形の剛性板２２に対して４角形の開口部４０が１対１の割合で出現する市松模様のパターンの構成としているが、剛性板の形は４角形でなくてもよく、また剛性板２２と開口部４０との比は１対１でなくても構わない。すなわち、同一形状かつ同一寸法の剛性板２２を組み合わせてこれら剛性板２２の間に剛性板と略同一又は略相似の開口部４０が一定のパターンで表れる構造であればよい。 The wall body 20 includes a plurality of rigid plates 22 arranged so as to be interchanged with each other with an opening 40 therebetween, and stiffening ribs 30 attached to the rigid plate 22. The rigid plate portion positioned on the outer peripheral portion of the wall body 20 is fixed to the support frame 14. This will be described later. The wall body 20 in the illustrated example has a checkered pattern configuration in which the rectangular openings 40 appear at a ratio of 1: 1 to the rectangular rigid plate 22, but the shape of the rigid plate is rectangular. The ratio between the rigid plate 22 and the opening 40 may not be 1: 1. That is, it is only necessary that the rigid plates 22 having the same shape and the same dimensions are combined and the openings 40 that are substantially the same as or substantially similar to the rigid plates appear between the rigid plates 22 in a certain pattern.
上記剛性板２２は、高強度の板材であり、剛性を有するとともに塑性変形可能な材料で形成することが多い。鋼板とすることが好適であるが、必ずしもこれに限定されるものではない。後述の補剛リブで座屈変形し易い箇所を効果的に補強するため、剛性板２２自体の厚さは小とすることができ、また補強リブ付きの剛性板全体の重量を従来のリブ無しの剛性板の重量より小とすることができる。 The rigid plate 22 is a high-strength plate material, and is often formed of a material having rigidity and plastic deformation. Although it is suitable to set it as a steel plate, it is not necessarily limited to this. In order to effectively reinforce a portion that is easily buckled and deformed by a stiffening rib, which will be described later, the thickness of the rigid plate 22 itself can be made small, and the weight of the entire rigid plate with the reinforcing rib can be reduced without the conventional rib. The weight of the rigid plate can be smaller.
上記剛性板２２は、角部Ａ及び辺部Ｓを有する多角形に形成される。本実施形態では剛性板２２を矩形としており、正方形を含む長方形以外に平行四辺形としてもよい。なお、壁体２０の外周部であってフレーム部２の内周面４に接する箇所においては、本来の壁体のパターン（図示例では市松模様）の剛性板２２の形状をフレーム部２の形状に対応して切除しても構わない。 The rigid plate 22 is formed in a polygon having a corner A and a side S. In the present embodiment, the rigid plate 22 is rectangular, and may be a parallelogram other than a rectangle including a square. It should be noted that the shape of the rigid plate 22 of the original wall pattern (checkered pattern in the illustrated example) is the shape of the frame portion 2 at the outer peripheral portion of the wall body 20 and in contact with the inner peripheral surface 4 of the frame portion 2. It may be excised correspondingly.
本実施形態においては、剛性板２２の角部Ａに第２留め孔２４を開口する。そして剛性板を前後２段に分けて配置し、図４に示すように、後段剛性板２２Ｂの角部Ａの上に前段剛性板２２Ｆの角部Ａを重ねて当接し、２つの角部の第２留め孔２４及び格子材１６の第１留め孔１８に固定具２８を挿通して、重ね合せた角部の組み合わせＡＣを格子材１６に固定する。そしてこの角部Ａの同士に連なる、２枚の剛性板２２の一方の辺部Ｓ同士（図１では上下方向に延びる辺部同士）及び他方の辺部同士（図１では水平方向に延びる辺部同士）がそれぞれ平行となるように設け、剛性板２２が一定のパターン（図示例では市松模様）で組み合わされるように構成する。壁体２０の外周部に位置する場所では、剛性板２２の角部Ａを支持枠１４に重ねて第２留め孔２４及び支持枠１４の取り付け孔１５に固定具２８を挿通させ、当該角部Ａを支持枠１４に固定している。また、壁体２０の外周部に位置する場所での固定にあたっては、格子材１６の両端部をフレーム部２の方向にそれぞれ延設し、剛性板２２の角部Ａを支持枠１４に重ねて第２留め孔２４、支持枠１４の取り付け孔１５、及び格子材１６の図示しない第１留め孔１８の順に重ねて固定具２８を挿通させ、当該角部Ａを支持枠１４に固定することも好適に実施できる。つまり、格子材１６の両端部１６ａを延設することで、格子材１６の支持枠１４に対する固定手段を兼ねることができる。 In the present embodiment, the second retaining holes 24 are opened at the corners A of the rigid plate 22. Then, the rigid plate is divided into two stages, front and rear, and as shown in FIG. 4, the corner A of the front rigid plate 22F is overlapped on and contacted with the corner A of the rear rigid plate 22B. A fixing tool 28 is inserted into the second fastening hole 24 and the first fastening hole 18 of the lattice material 16, and the combined corner combination AC is fixed to the lattice material 16. And one side S (two sides extending in the vertical direction in FIG. 1) and the other side (sides extending in the horizontal direction in FIG. 1) of the two rigid plates 22 connected to the corners A. And the rigid plates 22 are combined in a certain pattern (checkered pattern in the illustrated example). At a location located on the outer peripheral portion of the wall 20, the corner A of the rigid plate 22 is overlapped with the support frame 14, and the fixture 28 is inserted through the second retaining hole 24 and the attachment hole 15 of the support frame 14. A is fixed to the support frame 14. Further, when fixing at a position located on the outer peripheral portion of the wall body 20, both end portions of the lattice material 16 are extended in the direction of the frame portion 2, and the corner portion A of the rigid plate 22 is overlapped with the support frame 14. It is also possible to fix the corner A to the support frame 14 by inserting the fixture 28 in the order of the second fastening hole 24, the attachment hole 15 of the support frame 14, and the first fastening hole 18 (not shown) of the lattice material 16. It can be suitably implemented. That is, by extending both ends 16 a of the lattice material 16, the lattice material 16 can also serve as a fixing means for the support frame 14.
本実施形態では上述の固定具２８と第１留め孔１８と第２留め孔２４とで固定点Ｆを形成している。地震などの外力が作用するときには、対角方向の２つの固定点Ｆの間に引っ張り力又は圧縮力が作用する。 In the present embodiment, the fixing point F is formed by the above-described fixture 28, the first fastening hole 18, and the second fastening hole 24. When an external force such as an earthquake acts, a tensile force or a compressive force acts between the two fixed points F in the diagonal direction.
上記補剛リブ３０は、上記圧縮力による剛性板２２の座屈変形を防ぐために剛性板２２の表面（正面又は背面の何れも含む）に溶接などの手段で固設している。好適な図示例では、正面側の体裁を良くするために裏面側に設けているが、正面側に設けても構わない。 The stiffening rib 30 is fixed to the surface (including both front and back) of the rigid plate 22 by means such as welding in order to prevent buckling deformation of the rigid plate 22 due to the compressive force. In the preferred illustrated example, it is provided on the back side in order to improve the appearance on the front side, but it may be provided on the front side.
上記補剛リブ３０は、少なくとも剛性板２２の全ての辺部Ｓに対して等距離の場所を、好ましくは剛性板の図形中心よりも辺部Ｓの近くを通過するように形成されている。本実施形態では剛性板２２に対して垂直な方向から見て円形としている。しかしながらその構造は適宜変更することができ、例えば周方向の一部（剛性板の対角線と交差する箇所を除く）を省略した欠円形状としても構わない。 The stiffening ribs 30 are formed so as to pass at least equidistant locations with respect to all the side portions S of the rigid plate 22, preferably closer to the side portions S than the graphic center of the rigid plate. In this embodiment, it is circular when viewed from a direction perpendicular to the rigid plate 22. However, the structure can be changed as appropriate. For example, a part of the circumferential direction (except for a portion that intersects with the diagonal line of the rigid plate) may be omitted.
剛性板の座屈変形の原因となる外力は、主として図４に示す剛性板の内部領域Ｉ、すなわち隣り合う固定点Ｆ同士を仮想線分ＬＶで結ぶ多角形の内側の領域で作用する。従って補剛リブ３０は、少なくとも内部領域Ｉを通過するように設けることが好適である。しかしながら例えば補剛リブ３０を剛性板２２の図形中心Ｃの近傍にのみ設けても、座屈変形を防止できない。そこで補剛リブ３０は、剛性板２２の隣り合う固定点Ｆを結ぶ仮想線分ＬＶに近接するように形成する。このとき補剛リブ３０で囲まれる領域は内部領域の大半を占めている。この構成は変形することができ、上記補剛リブ３０が上記仮想線分と交接してもよい。 External force causes buckling of the rigid plate acts mainly internal region I of the rigid plate shown in FIG. 4, namely the fixed point F adjacent to each other in the region inside the polygon connecting the virtual line L V. Therefore, it is preferable that the stiffening rib 30 is provided so as to pass through at least the inner region I. However, even if the stiffening rib 30 is provided only near the figure center C of the rigid plate 22, buckling deformation cannot be prevented. Therefore stiffening rib 30 is formed so as to be closer to the virtual line L V connecting the fixed point F adjacent the rigid plate 22. At this time, the region surrounded by the stiffening rib 30 occupies most of the inner region. This configuration can be modified, and the stiffening rib 30 may intersect the imaginary line segment.
図示例では、上記補剛リブ３０は、既存の鋼管をリング状に切り出し、その端部の全部又は一部を剛性板２２に溶接してなる。図示例では、円形鋼管を切り出しているが、例えば図８に示すような角形鋼管を切り出してもよい。 In the illustrated example, the stiffening rib 30 is formed by cutting an existing steel pipe into a ring shape and welding all or part of its end to the rigid plate 22. In the illustrated example, a circular steel pipe is cut out, but for example, a square steel pipe as shown in FIG. 8 may be cut out.
図７は、本発明に係る剛性板耐震壁の原理を示すための図である。同図（Ａ）は、当該剛性板耐震壁の原理に関わる基本的構成を簡単に表現している。支持手段のうちの格子材は必ずしも必須の構成ではないので、省略している。支持手段の支持枠１４は同図に記載されているが、これも省略して剛性板耐震壁を柱梁構造に直接連結しても構わない。同図（Ｂ）は剛性板耐震壁を適用したフレーム部に地震力が作用した場合の様子を描いている。 上述の構成によれば、剛性板２２同士の角部を固定点で固定するとともに固定点同士を結ぶ仮想線分に近接又は交接する補剛リブ３０を付設したから、比較的薄い板材を用いて有効に座屈変形を防止することができる。すなわち、剛性板及び補剛リブの三次元的構造により単に一枚の剛性材の厚みを増加させるよりも効果的に補剛効果を得ることができるので、全体として耐震壁を軽量とすることができる。 FIG. 7 is a diagram for illustrating the principle of the rigid plate earthquake resistant wall according to the present invention. FIG. 5A simply represents a basic configuration related to the principle of the rigid plate shear wall. Since the lattice material of the support means is not necessarily an essential configuration, it is omitted. Although the support frame 14 of the support means is shown in the figure, this may be omitted and the rigid plate earthquake resistant wall may be directly connected to the column beam structure. FIG. 5B illustrates a state where a seismic force is applied to the frame portion to which the rigid plate shear wall is applied. According to the above-described configuration, since the corners of the rigid plates 22 are fixed at the fixed points and the stiffening ribs 30 that are close to or intersect with the imaginary line segment connecting the fixed points are attached, a relatively thin plate material is used. It is possible to effectively prevent buckling deformation. That is, the three-dimensional structure of the rigid plate and the stiffening rib can provide a stiffening effect more effectively than simply increasing the thickness of a single rigid member, so that the seismic wall as a whole can be reduced in weight. it can.
ここで参考例である図１７と比較して本願発明の作用を説明する。この参考例では、補剛リブを設けない剛性板の角部同士を重ね合わせて一個の固定具で連結して耐震壁を構成するものとしている。図１７は、当該方向を一枚の剛性板の対角線が通る位置で切断した形状を描いている。なお、格子材については作図を省略している。参考例では、補剛リブで補剛していない一枚の剛性板の一方の対角線方向に図１７に矢示する引っ張り力が作用し、他方の対角線の方向に圧縮力が作用すると、まず剛性板全体が大きく弯曲する。これにより各剛性板の角部同士を連結するボルトも傾き、そして角部Ａが反るように変形する。そうすると角部同士の摩擦力が低下する。これを避けるために従来例では、剛性板の角部の複数個所をボルト留めしていた。本願発明では、剛性板２２に補剛リブ３０を設けたから剛性板２２の弯曲を回避することができ、それによりボルトなどの固定具の個数を削減することができる。 Here, the operation of the present invention will be described in comparison with FIG. 17 as a reference example. In this reference example, corners of rigid plates not provided with stiffening ribs are overlapped and connected with a single fixture to form a seismic wall. FIG. 17 illustrates a shape obtained by cutting the direction at a position where a diagonal line of one rigid plate passes. Note that drawing of the lattice material is omitted. In the reference example, when a tensile force indicated by an arrow in FIG. 17 acts in one diagonal direction of one rigid plate not stiffened by a stiffening rib, and a compressive force acts in the other diagonal direction, the rigidity is first The whole board is greatly bent. As a result, the bolts connecting the corners of the rigid plates are also tilted and deformed so that the corners A are warped. If it does so, the frictional force of corner parts will fall. In order to avoid this, in the conventional example, a plurality of corners of the rigid plate are bolted. In the present invention, since the stiffening ribs 30 are provided on the rigid plate 22, bending of the rigid plate 22 can be avoided, whereby the number of fixtures such as bolts can be reduced.
以下本発明の他の実施形態について説明をする。これらの説明において、第１実施形態と同じ構成については解説を省略する。 Other embodiments of the present invention will be described below. In these descriptions, the description of the same configuration as that of the first embodiment is omitted.
図８から図１０は、本発明の第２実施形態に係る剛性板耐震壁を示している。本実施形態では、補剛リブ３０を、剛性板２２の輪郭と相似な多角形状（図示例では４角形）に形成している。そして補剛リブ３０は剛性板２２の外周端部に沿って当該端部からの距離が一定となるように配置されており、補剛リブ３０が有する４つの隅角部３４において第１実施形態に比べて剛性板２２の角部Ａにより接近するようにしている。これにより前述した剛性板２２の角部Ａにおける変形を有効に制限できる。 8 to 10 show a rigid plate earthquake resistant wall according to the second embodiment of the present invention. In the present embodiment, the stiffening rib 30 is formed in a polygonal shape (a quadrangle in the illustrated example) similar to the contour of the rigid plate 22. The stiffening rib 30 is arranged along the outer peripheral end portion of the rigid plate 22 so that the distance from the end portion is constant, and the four corner portions 34 of the stiffening rib 30 have the first embodiment. As compared with the above, the corner portion A of the rigid plate 22 is made closer. Thereby, the deformation | transformation in the corner | angular part A of the rigid board 22 mentioned above can be restrict | limited effectively.
図１１から図１２は、本発明の第３実施形態に係る剛性板耐震壁を示している。本実施形態では、補剛リブ３０を格子材１６と反対側（図示例では正面側）に設置したものである。格子材１６に邪魔されずに補剛リブ３０の大きさを設計することが可能である。例えば補剛リブ３０が剛性板２２の角部Ａの近傍を通過するように設け、当該角部Ａの好ましくない変形を抑制することができる。 11 to 12 show a rigid plate earthquake-resistant wall according to the third embodiment of the present invention. In the present embodiment, the stiffening ribs 30 are installed on the side opposite to the lattice material 16 (front side in the illustrated example). It is possible to design the size of the stiffening rib 30 without being obstructed by the lattice material 16. For example, the stiffening rib 30 can be provided so as to pass in the vicinity of the corner A of the rigid plate 22, and undesirable deformation of the corner A can be suppressed.
図１３から図１４は、本発明の第５実施形態に係る剛性板耐震壁を示している。この実施例では、剛性板２２を三角形状としている。隣接する３つの剛性板２２の角部Ａ同士を重ね合わせるとともに、この角部同士の組み合わせＡＣを貫通する一個の固定具２８で、当該角部同士に連なる対応する２つの辺部Ｓが平行となるように連結し、全体として規則正しい一定のパターンとなるように構成する。第１実施形態と同様に剛性板２２と開口部４０とが一対一の割合で出現するので、第１実施形態のものと同様に軽量の剛性板耐震壁１０を構成することができる。 13 to 14 show a rigid plate earthquake resistant wall according to the fifth embodiment of the present invention. In this embodiment, the rigid plate 22 has a triangular shape. The corners A of the three adjacent rigid plates 22 are overlapped with each other, and the two corresponding side portions S connected to the corners are parallel to each other with one fixture 28 penetrating the combination AC of the corners. It connects so that it may become, and it is comprised so that it may become a regular regular pattern as a whole. Since the rigid plate 22 and the opening 40 appear in a one-to-one ratio as in the first embodiment, the lightweight rigid plate earthquake-resistant wall 10 can be configured in the same manner as in the first embodiment.
剛性板２２の形状は、適宜変更することができ、図示例では正三角形状であるが、二等辺三角形状、直角三角形状でも構わない。図示例において、各剛性板２２は、基本的に同一形状・同一寸法であるが、フレーム部２の内周面４の輪郭に対応するように、壁体２０の外周部に位置する剛性板２２は、正三角形状の略半分に相当する直角三角形状としている。また当該剛性板については、補剛リブを設けることを省略している。 The shape of the rigid plate 22 can be changed as appropriate. In the illustrated example, the shape is an equilateral triangle, but it may be an isosceles triangle or a right triangle. In the illustrated example, the rigid plates 22 have basically the same shape and the same dimensions, but the rigid plates 22 positioned on the outer peripheral portion of the wall body 20 so as to correspond to the contour of the inner peripheral surface 4 of the frame portion 2. Is a right triangle shape corresponding to approximately half of the regular triangle shape. Further, the stiffening rib is omitted from the rigid plate.
図１４（Ａ）は、３枚の剛性板２２の角部Ａ同士を格子材１６に固定した箇所の構造を断面図で示している。すなわち、本実施形態では、同図に示す如く剛性板を前中後の３段に分けて配置し、後段剛性板２２Ｂの角部Ａ、中段剛性板２２Ｍの角部Ａ、及び前段剛性板２２Ｆの角部を順次重ねて、これら角部同士の組み合わせＡＣの第１留め孔１８と格子材１６の第２留め孔２４に固定具２８を挿通して固定している。格子材１６は、三角形状の剛性板２２の３つの辺部Ｓの何れかの方向（図示例では水平方向）に設置すればよい。 FIG. 14A shows a cross-sectional view of the structure of the portion where the corners A of the three rigid plates 22 are fixed to the lattice material 16. That is, in this embodiment, the rigid plates are arranged in three stages, the front, middle, and rear, as shown in the figure, the corner A of the rear rigid plate 22B, the corner A of the middle rigid plate 22M, and the front rigid plate 22F. These corners are sequentially stacked, and a fixture 28 is inserted and fixed to the first fastening hole 18 of the combination AC of these corners and the second fastening hole 24 of the lattice material 16. The lattice material 16 may be installed in any direction (horizontal direction in the illustrated example) of the three sides S of the triangular rigid plate 22.
図１４（Ｂ）は、１枚の剛性板２２の角部Ａを支持枠１４（図示例では上側の横枠）に固定した箇所の構造を示している。この場合、後段剛性板２２Ｂの角部Ａを支持枠１４に当接した状態において、前段剛性板２２Ｆの角部Ａと支持枠１４との間、中段剛性板２２Ｍの角部Ａと支持枠１４との間には間隔が生ずる。このため、後段剛性板２２Ｂの角部Ａは支持枠１４に直接連結するとともに、中段剛性板２２Ｍは、剛性板一枚分の厚さに相当するスペーサ３６を介して、前段剛性板２２Ｆは、剛性板二枚分の厚さに相当するスペーサ３６を介してそれぞれ支持枠１４に連結する。支持枠１４の縦枠１４ａと一枚の剛性板２２の角部Ａとの間にも必要により対応する厚さのスペーサを介在させて連結する。支持枠１４の下側の横枠においても、剛性板の角部と支持枠との間、或いは剛性板の角部同士の間に、必要によりスペーサを介在させて連結する。 FIG. 14B shows the structure of a portion where the corner portion A of one rigid plate 22 is fixed to the support frame 14 (the upper horizontal frame in the illustrated example). In this case, in a state where the corner portion A of the rear rigid plate 22B is in contact with the support frame 14, between the corner portion A of the front rigid plate 22F and the support frame 14, between the corner portion A of the middle rigid plate 22M and the support frame 14. There is a gap between the two. Therefore, the corner portion A of the rear rigid plate 22B is directly connected to the support frame 14, and the intermediate rigid plate 22M is connected to the front rigid plate 22F via the spacer 36 corresponding to the thickness of one rigid plate. Each of them is connected to the support frame 14 via a spacer 36 corresponding to the thickness of two rigid plates. The vertical frame 14a of the support frame 14 and the corner portion A of the single rigid plate 22 are also connected with a spacer having a corresponding thickness as necessary. The lower frame of the support frame 14 is also connected with a spacer between the corners of the rigid plate and the support frame, or between the corners of the rigid plate, if necessary.
図１５は、本発明の第５実施形態に係る剛性板耐震壁を示している。本実施形態では、剛性板２２のうちでフレーム部２と隣接するもの（換言すれば、フレーム部に対して連結されたもの）について補剛リブ３０の設置を省略している。フレーム部２から離れた剛性板２２ほどに好ましくない変形を生じ易いからである。これによって、より少ない材料で効率的に補剛効果を実現することができる。 FIG. 15 shows a rigid plate earthquake-resistant wall according to the fifth embodiment of the present invention. In the present embodiment, installation of the stiffening rib 30 is omitted for the rigid plate 22 adjacent to the frame portion 2 (in other words, connected to the frame portion). This is because deformation which is not as desirable as the rigid plate 22 that is separated from the frame portion 2 is likely to occur. Thereby, the stiffening effect can be efficiently realized with less material.
図１６は、本発明の第４実施形態に係る剛性板耐震壁を示している。本実施形態では、隣接する剛性板２２の角部Ａ同士を、重ね合わせずに近接させ、各角部Ａをそれぞれ格子材１６に対して固定したものである。固定する方法に関しては第１実施形態と同様に固定具２８で固定すればよい。 FIG. 16 shows a rigid plate earthquake resistant wall according to the fourth embodiment of the present invention. In the present embodiment, the corners A of the adjacent rigid plates 22 are brought close to each other without being overlapped, and each corner A is fixed to the lattice material 16. The fixing method may be fixed by the fixing tool 28 as in the first embodiment.
なお、本発明の実施形態は発明の理解に資するために記載されたものであり、本発明の技術的範囲がこれらの態様に限定されるものと理解すべきではない。 The embodiments of the present invention are described for the purpose of understanding the invention, and it should not be understood that the technical scope of the present invention is limited to these embodiments.
