Description

本発明は、既存建物の柱梁接合部に設置して建物を耐震補強するための既存建物用耐震補強装置に関するもので、特に中高層の多層階建物の耐震補強に適している。   The present invention relates to a seismic reinforcement device for an existing building that is installed at a column beam joint of an existing building and reinforced the building against earthquakes, and is particularly suitable for seismic reinforcement of middle- and high-rise multi-story buildings.

地震国である我が国おいては、過去の大地震による教訓をもとに、耐震に関する考え方が都度見直されている。そのような状況下において、旧耐震の設計による既存の建物の構造では、今後予想される大地震に対しては耐震性能が十分ではないという問題がある。   In Japan, an earthquake-prone country, the idea of earthquake resistance is reviewed each time based on lessons learned from past major earthquakes. Under such circumstances, the existing building structure based on the old seismic design has a problem that the seismic performance is not sufficient for a large earthquake expected in the future.

このようなことから、既存の建物については、建て替えによらずに耐震性能を大幅に向上させることができる耐震補強構造あるいは耐震補強方法が望まれており、種々の構造、方法が提案されている。   For these reasons, for existing buildings, there is a demand for an earthquake-resistant reinforcement structure or method that can greatly improve earthquake-resistance performance without rebuilding, and various structures and methods have been proposed. .

ところで、都会など地価が高価な地域では、ペンシルビルなど間口の狭い多層階のビルが多数建設されている。このようなペンシルビルはその形態から、桁行き方向は比較的耐震性が高いが、梁間方向の固有周期が長く、比較的長周期の地震動による横揺れが大きくなる傾向があるという問題がある。   By the way, in areas with high land prices such as urban areas, many multi-storey buildings with narrow frontage such as pencil buildings have been constructed. Due to the shape of such a pencil building, the girder direction has a relatively high earthquake resistance, but the natural period in the interbeam direction is long, and there is a problem that the roll due to a relatively long period of ground motion tends to increase.

また、ペンシルビルはもともと狭隘な敷地に建設されることが多いため、建物外部からの耐震補強が難しいといった問題もある。   Pencil buildings are often built on a narrow site, which makes it difficult to reinforce earthquake resistance from outside the building.

建物の制震に関する技術として、例えば特許文献1には、建物の柱梁架構を構成する構面内に,第一と第二の粘弾性ダンパーをハの字形または逆ハの字形となるように配置した複合制振架構が開示されている。   As a technique related to building vibration control, for example, Patent Document 1 discloses that the first and second viscoelastic dampers are formed in a C shape or an inverted C shape in the structural surface constituting the column beam structure of the building. An arranged composite damping frame is disclosed.

また、柱梁接合部に耐震要素を設ける技術として、例えば特許文献2には、木造家屋の柱と梁または梁どうしの接合部に、粘弾性ダンパーを組み込んだ方杖および火打を取り付けた構造が開示されている。   In addition, as a technique for providing an earthquake-resistant element at a joint between columns and beams, for example, Patent Document 2 discloses a structure in which a stick and a hammer that incorporate a viscoelastic damper are attached to a joint between a column and a beam or a beam of a wooden house. It is disclosed.

特許文献3には、建物の柱と梁との接合の形態をピン接合とし、それらの接合部に、層間変位による柱と梁との相対回転により作動するダンパーを介装した制震構造建物が開示されている。   Patent Document 3 discloses a vibration-damping structure building in which a form of a connection between a column and a beam of a building is a pin connection, and a damper that operates by a relative rotation between the column and the beam due to an interlayer displacement is interposed in the connection part. It is disclosed.

特許文献4には、可動支承及びダンパーが建物の架構内に配置され、上側の架構を下側の架構上に水平方向相対変位可能に支持する可動支承と、下側の架構と上側の架構の間に介在されたダンパーとを並列に備える制震構造が開示されている。   In Patent Document 4, a movable bearing and a damper are arranged in a building frame, and a movable bearing that supports the upper frame on the lower frame so as to be relatively displaceable in the horizontal direction, and a lower frame and an upper frame. A seismic control structure including a damper interposed in parallel is disclosed.

特許文献5には、鋼材からなる柱と大梁とを剛接合してなる柱梁接合部の近傍に、柱と大梁とに亘ってダンパー性能を有する方杖材を架設して補強された架構の補強構造が開示されている。   Patent Document 5 discloses a reinforced structure in which a brace member having a damper performance is erected between a column and a large beam in the vicinity of a column beam joint formed by rigidly connecting a column made of a steel material and a large beam. A reinforcing structure is disclosed.

また、特許文献6には、建物の柱・梁架構側と、建物に制震装置を取り付ける片持ちの制震装置用取付部材の自由端部側とに、制震装置と並設させて弾性部材を架設する構成において、これら制震装置と弾性部材を天井裏などに納める制震装置の取付構造が開示されている。   Further, Patent Document 6 discloses an elastic structure in which a seismic control device is juxtaposed on a column / beam frame side of a building and a free end portion of a cantilever mounting device for mounting a seismic control device on a building. In a configuration in which members are installed, a structure for mounting a vibration control device in which the vibration control device and an elastic member are stored in a ceiling or the like is disclosed.

特許文献1に記載される発明のように、壁内に上下階の梁または柱をつなぐダンパーを設置する方式は、既存の建物に適用する場合、ダンパーの設置のために大がかりな改修が必要となる。   As in the invention described in Patent Document 1, the method of installing a damper that connects a beam or a column on the upper and lower floors in a wall requires a major renovation for installing the damper when applied to an existing building. Become.

特許文献2および特許文献5に記載される発明の場合、ダンパーを方杖あるいは火打に設けることで制震装置としてはコンパクトな構造となっているが、これらの発明においてダンパーは減衰力を与えるのが主であり、また面外方向の力には効かないため、柱梁架構に対する補強効果は小さい。   In the case of the inventions described in Patent Document 2 and Patent Document 5, the damper is provided on the wand or firestroke to provide a compact structure as a vibration control device. However, in these inventions, the damper gives a damping force. However, the reinforcement effect on the column beam frame is small.

特許文献3および特許文献4に記載された発明の場合、既存の建物に後から組み込むことは実質的に不可能である。   In the case of the inventions described in Patent Document 3 and Patent Document 4, it is practically impossible to incorporate them into an existing building later.

特許文献6に記載された発明は、制震装置と弾性部材を天井裏などに納めることができたとしても、柱梁架構の壁内に上下階にわたる取付け部材が必要であり、コンパクトな装置とは言えない。   Even if the invention described in Patent Document 6 can accommodate the vibration control device and the elastic member in the back of the ceiling or the like, a mounting member extending up and down the floor is required in the wall of the column beam frame. I can't say that.

本発明は上述のような従来技術における課題の解決を図ったものであり、既存建物の柱梁接合部にコンパクトに取り付けることができ、かつ柱梁接合部に対する補強効果およびダンパーによる減衰効果を効果的に発揮することができる既存建物用耐震補強装置を提供することを目的としている。   The present invention is intended to solve the above-described problems in the prior art, and can be compactly attached to a beam-column joint of an existing building, and has a reinforcing effect on the beam-column joint and a damping effect by a damper. The purpose is to provide a seismic reinforcement device for existing buildings that can be used effectively.

本発明は、既存建物の柱梁接合部に設置して建物を耐震補強する既存建物用耐震補強装置であって、柱梁接合部の交差する2方向の梁に沿って延びる水平2方向の梁添接部材と、前記2方向の梁添接部材の交点から上方または下方に延びる柱添接部材と、前記2方向の梁添接部材の先端部間をつなぐ棒状の水平ダンパーと、それぞれ前記柱添接部材の先端部と前記2方向の梁添接部材の先端部間をつなぐ2本の棒状の斜めダンパーとが略三角錐形状の6辺を形成するように立体トラス状に連結されて前記柱梁接合部の地震時の振動に抵抗し、前記柱梁接合部の所定以上の振動に対しては前記水平ダンパーおよび前記斜めダンパーが振動エネルギーを吸収するように構成したことを特徴とするものである。   The present invention relates to a seismic reinforcement apparatus for an existing building which is installed at a beam-column joint of an existing building and reinforced the building against earthquakes, and is a horizontal bi-directional beam extending along two beams intersecting the beam-column joint An attachment member, a column attachment member extending upward or downward from an intersection of the two-direction beam attachment members, a bar-shaped horizontal damper connecting between the tip portions of the two-direction beam attachment members, and the columns The tip of the attachment member and the two rod-shaped diagonal dampers connecting between the two ends of the beam attachment member in the two directions are connected in a three-dimensional truss shape so as to form six sides of a substantially triangular pyramid shape. Resisting the vibration of the beam-column joint during an earthquake, the horizontal damper and the oblique damper absorb the vibration energy against the vibration of the column-beam joint more than a predetermined value. It is.

従来の方杖位置あるいは火打位置に個別に配置されるダンパーの場合、面外方向の力に対して不安定であるのに対し、本発明の耐震補強装置では2本の梁添接部材と1本の柱添接部材、および1本の水平ダンパーと2本の斜めダンパーが立体トラス状に配置されていることで、どの方向の力に対しても機能させることができ、柱梁接合部の剛性を高める補強要素としても耐震補強効果を発揮することができる。   In the case of the dampers individually arranged at the position of the conventional wand or fire, it is unstable with respect to the force in the out-of-plane direction, whereas the seismic reinforcement apparatus of the present invention has two beam attachment members and 1 Since the column attachment members, one horizontal damper and two diagonal dampers are arranged in a three-dimensional truss shape, it can function in any direction force. As a reinforcing element that increases rigidity, it is possible to exert an earthquake-proof reinforcing effect.

その上で、大きな地震動に対して水平ダンパーおよび斜めダンパーが水平方向および鉛直方向の振動だけでなく、建物のねじれに対しても機能し、大きな減衰効果を与えることができる。   In addition, the horizontal damper and the diagonal damper function not only in the horizontal and vertical vibrations but also in the torsion of the building against a large earthquake motion, and can provide a great damping effect.

本発明の耐震補強装置を構成する梁添接部材と柱添接部材としては棒状または板状の鋼材などを用いることができる。梁添接部材と柱添接部材を水平ダンパーおよび斜めダンパーとともに柱梁接合部の補強要素とするためには、補強に必要な強度、剛性を備えた部材とする必要がある。柱梁接合部への納まりを考慮して、棒状、板状、アングル状などの鋼材を用いることができる。   As the beam attaching member and the column attaching member constituting the seismic reinforcement apparatus of the present invention, a rod-like or plate-like steel material or the like can be used. In order to use the beam attachment member and the column attachment member together with the horizontal damper and the diagonal damper as a reinforcing element of the column beam joint portion, it is necessary to provide a member having strength and rigidity necessary for reinforcement. In consideration of accommodation in the beam-column joint, steel materials such as rods, plates, and angles can be used.

なお、実際の既存の建物では、柱の出隅部が交差する2方向の梁の側面に対し飛び出ているケースも多いが、その場合、柱添接部材の水平断面をL字状としたり、出隅部の両側に位置する2本の部材を抱き合わせた形の柱添接部材を用いるなどして、適用対象となる建物の柱梁接合部の形状に合わせて対処すればよい。   In addition, in actual existing buildings, there are many cases where the protruding corners of the pillars protrude to the side surfaces of the two beams that intersect, but in that case, the horizontal section of the column attachment member is L-shaped, What is necessary is just to cope with the shape of the column beam joint part of the building used as an application object, for example, using the column attachment member of the shape which entangled two members located in the both sides of a protruding corner part.

あるいは、柱の出隅部が飛び出している場合に、2方向の梁の側面に版状のスペーサーを介在させるなどして出隅部の飛び出しをなくした形で本発明の耐震補強装置を取り付けてもよい。   Alternatively, if the protruding corner of the column is protruding, attach the seismic reinforcement device of the present invention in such a way that the protruding corner is not protruded by interposing a plate-like spacer on the side of the beam in two directions. Also good.

また、本発明の耐震補強装置は、主として柱梁接合部の変形に抵抗しつつ、入力される地震動を減衰させるものであるため、柱や梁の中間部分のせん断に対しては鋼板巻立て工法、繊維シート巻立て工法などによる耐震補強を施したり、壁位置に別途耐震補強要素を組み込んだり、あるいは例えば建物頂部などに能動型あるいは受動型制震装置を設置するなど他の制震手段を併用すれば建物全体の耐震性をさらに高めることができる。   In addition, the seismic reinforcement device of the present invention mainly attenuates the input seismic motion while resisting deformation of the column-beam joint, so that the steel sheet winding method is used for shearing the intermediate portion of the column or beam. Use other seismic control means, such as by applying seismic reinforcement by fiber sheet winding method, installing seismic retrofit elements at the wall position, or installing active or passive seismic control devices at the top of the building, etc. This can further increase the earthquake resistance of the entire building.

また、梁添接部材と柱添接部材との接合部は接合状態において角度調整が可能な接合部とすれば、柱梁接合部に設置する際に、柱梁接合部が直角でない場合や柱梁接合部の微妙な歪みなどに対処させることができる。具体的にはボルトなどを利用したピン構造の締め付け部分での調整やボルト孔を長孔あるいはばか孔として調整する構造などが考えられる。   Also, if the joint between the beam attachment member and the column attachment member is a joint whose angle can be adjusted in the joined state, when it is installed at the column beam joint, the column beam joint may not be perpendicular or It can deal with subtle distortions in the beam joint. Specifically, adjustment at the tightening portion of the pin structure using a bolt or the like, or a structure in which the bolt hole is adjusted as a long hole or a fool hole can be considered.

水平ダンパーおよび斜めダンパーは、部材全体がダンパーである必要はなく、鋼材の中間にダンパーを組み込んだものでもよい。ダンパー自体は既存の摩擦ダンパー、軸力降伏履歴型鋼製ダンパー、棒状粘性ダンパーなどを利用することができる。   The horizontal damper and the oblique damper do not need to be a damper as a whole member, and may be one in which a damper is incorporated in the middle of the steel material. As the damper itself, an existing friction damper, an axial force yield hysteresis steel damper, a rod-like viscous damper, or the like can be used.

また、例えば中間にネジ式の長さ調整部材あるいはターンバックルなどを組み込むなどして長さ調整可能としておけば、設置に際して軸方向の力が作用しない状態で長さ調整が可能となる。   For example, if the length can be adjusted by incorporating a screw-type length adjusting member or a turnbuckle in the middle, the length can be adjusted without any axial force acting upon installation.

その他、梁添接部材、柱添接部材、水平ダンパー、斜めダンパーの端部形態によっては、接合部にボールジョイントその他立体トラス用の継手を利用することもできる。   In addition, depending on the end form of the beam attachment member, the column attachment member, the horizontal damper, and the oblique damper, a ball joint or other joint for a three-dimensional truss can be used as the joint.

本発明の既存建物用耐震補強装置を適用する建物の形態は特に限定されないが、中高層の多層階建物に適し、特にRCまたはSRC構造の既存のペンシルビルに適用した場合、設置が簡単であり、高い耐震効果が期待できる。   The form of the building to which the seismic reinforcement device for an existing building of the present invention is applied is not particularly limited, but it is suitable for a middle-to-high-rise multi-story building, particularly when applied to an existing pencil building with an RC or SRC structure, and installation is simple. High earthquake resistance can be expected.

本発明の耐震補強装置では2本の梁添接部材と1本の柱添接部材、および1本の水平ダンパーと2本の斜めダンパーが立体トラス状に配置されていることで、どの方向の力に対しても機能させることができ、柱梁接合部の剛性を高める補強要素としても補強効果を発揮することができる。   In the seismic reinforcement device of the present invention, two beam attachment members, one column attachment member, one horizontal damper and two oblique dampers are arranged in a three-dimensional truss shape, so It can be made to function with respect to force, and can also exert a reinforcing effect as a reinforcing element that increases the rigidity of the beam-column joint.

その上で、大きな地震動に対して水平ダンパーおよび斜めダンパーが水平方向および鉛直方向の振動だけでなく、建物のねじれに対しても機能し、大きな減衰効果を与えることができる。   In addition, the horizontal damper and the diagonal damper function not only in the horizontal and vertical vibrations but also in the torsion of the building against a large earthquake motion, and can provide a great damping effect.

装置の全体形状が略三角錐(四面体)形状の立体トラス状の形態であるため、それ自体が安定した構造となっており、既存建物の柱梁接合部の入隅部などにコンパクトに取り付けることができる。   Since the overall shape of the device is a three-dimensional truss-like shape with a substantially triangular pyramid shape, it itself has a stable structure and is compactly attached to the corners of the column beam joints of existing buildings. be able to.

以下、本発明の一実施形態を添付図面に基づいて説明する。
図1は本発明の耐震補強装置1を既存建物の柱梁接合部に取り付けた状態を斜め下方から見た図である。
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a view of a state in which the seismic reinforcement device 1 of the present invention is attached to a column beam joint of an existing building as viewed obliquely from below.

この耐震補強装置1は、2本の梁添接部材2と、1本の柱添接部材3と、1本の水平ダンパー4と、2本の斜めダンパー5の合計6本の棒状要素を略三角錐形状の6辺を形成するように立体トラス状に連結して構成されている。   This seismic reinforcement device 1 is composed of a total of six rod-like elements including two beam attachment members 2, one column attachment member 3, one horizontal damper 4, and two diagonal dampers 5. It is configured to be connected in a three-dimensional truss shape so as to form six sides of a triangular pyramid shape.

この例では、耐震補強装置1が、図に示すように既存の建物の柱11と交差する2方向の梁12の入隅部に設置され、柱添接部材3が柱11の出隅部分に取り付けられ、2本の梁添接部材2が交差する2方向の梁12の下部に取り付けられている。   In this example, as shown in the figure, the seismic reinforcement device 1 is installed at the entrance corner of the beam 12 in the two directions intersecting the pillar 11 of the existing building, and the column attachment member 3 is provided at the exit corner of the column 11. It is attached to the lower part of the two-way beam 12 where the two beam attachment members 2 intersect.

梁添接部材2および柱添接部材3は形鋼などの棒状の鋼材からなり、水平ダンパー4および斜めダンパー5には摩擦ダンパー、あるいは軸力降伏履歴型鋼製ダンパー、棒状粘性ダンパーなどが用いられる。このようなダンパーは既存の市販のものを用いることができるが、必要に応じて接合部の構造などを変更して用いることができる。   The beam attachment member 2 and the column attachment member 3 are made of a rod-shaped steel material such as a shape steel, and the horizontal damper 4 and the oblique damper 5 are friction dampers, axial-yield hysteresis steel dampers, rod-like viscous dampers, or the like. It is done. As such a damper, an existing commercially available damper can be used, but it can be used by changing the structure of the joint as required.

図2は耐震補強装置1の基本形態を原理図として示したもので、このような構成において、2本の梁添接部材2と1本の柱添接部材3、および1本の水平ダンパー4と2本の斜めダンパー5が立体トラス状に配置されていることで、どの方向の力に対しても機能させることができ、柱梁接合部の剛性を高める補強要素としても補強効果を発揮することができる。   FIG. 2 shows a basic form of the seismic reinforcement device 1 as a principle diagram. In such a configuration, two beam attaching members 2, one column attaching member 3, and one horizontal damper 4 are provided. And two diagonal dampers 5 are arranged in a three-dimensional truss shape, so that they can function in any direction and exert a reinforcing effect as a reinforcing element that increases the rigidity of the beam-column joint. be able to.

その上で、大きな地震動に対しては、水平ダンパー4および斜めダンパー5が水平方向および鉛直方向の振動だけでなく、建物のねじれに対しても機能し、大きな減衰効果を与えることができる。   In addition, for large earthquake motions, the horizontal damper 4 and the diagonal damper 5 function not only in the horizontal and vertical vibrations but also in the torsion of the building, and can provide a great damping effect.

本発明の耐震補強装置1は装置の全体形状が略三角錐形状の立体トラス状の形態であるため、それ自体が安定した構造となっており、既存建物の柱梁接合部の入隅部などにコンパクトに取り付けることができる。適用対象となる既存建物の構造によっては、装置全体または装置の一部を天井内に納めることもでき、またハンチ状の内装によって隠すこともできる。   The seismic reinforcement device 1 of the present invention is a three-dimensional truss-like shape in which the overall shape of the device is a substantially triangular pyramid shape. Can be mounted compactly. Depending on the structure of the existing building to be applied, the entire device or a part of the device can be stored in the ceiling, or can be hidden by a haunch-like interior.

図3は本発明の耐震補強装置1をペンシルビルに設置する場合の設置位置の例を示したものである。この例では既存建物Aの各階の柱梁接合部に取り付けているが、1階おき、あるいは複数階おきに設置したり、既存建物の上層階に多くなるように設置するなど、適用対象となる既存建物の耐力や振動特性に応じて配置計画を立てればよい。   FIG. 3 shows an example of an installation position when the seismic reinforcement device 1 of the present invention is installed in a pencil building. In this example, it is attached to the beam-column joint on each floor of the existing building A, but it is applicable to install every other floor, every other floor, or on the upper floor of the existing building. An arrangement plan may be made according to the strength and vibration characteristics of the existing building.

図4は本発明の耐震補強装置1の取付け形態に関する応用例を斜め上方から見た図である。この応用例は、図1の実施形態における耐震補強装置1の上部に、耐震補強装置1をもう1つ上下逆配置となるように取り付けたものである。このように配置することで、柱梁接合部の1箇所の入隅部に2つの耐震補強装置1を取り付けることができ、耐震効果を高めることができる。あるいは、1つの耐震補強装置と同程度の耐震効果をより小型の2つの耐震補強装置で付与することができる。   FIG. 4 is a view of an application example related to the mounting form of the seismic reinforcement device 1 of the present invention as viewed obliquely from above. In this application example, another seismic reinforcement device 1 is attached to the upper part of the seismic reinforcement device 1 in the embodiment of FIG. By arrange | positioning in this way, the two earthquake-resistant reinforcement apparatuses 1 can be attached to the one corner of a column beam junction part, and an earthquake-resistant effect can be heightened. Alternatively, the seismic effect equivalent to that of one seismic reinforcement device can be provided by two smaller seismic reinforcement devices.

図5は本発明の耐震補強装置1の他の取付け形態の例を示したものである。図1の例では梁添接部材2の取付け位置が柱梁接合部の梁12のほぼ下端位置であるのに対し、図5の例では梁添接部材2の取付け位置を柱梁接合部の梁12の梁成中間位置近傍としているため、耐震補強装置1ほぼ天井裏に納めることができる。   FIG. 5 shows an example of another attachment form of the seismic reinforcement apparatus 1 of the present invention. In the example of FIG. 1, the attachment position of the beam attachment member 2 is substantially the lower end position of the beam 12 at the beam-column joint, whereas in the example of FIG. Since it is in the vicinity of the beam forming intermediate position of the beam 12, the seismic reinforcement device 1 can be placed almost in the ceiling.

図6は本発明の耐震補強装置1のさらに他の取付け形態の例を示したものである。柱梁接合部との取り合いにおいて、梁添接部材2および柱添接部材3を安定的に固定し難しい場合などには、図6に示すように鋼板などからなるフランジ状固定金具7を設け、フランジ状固定金具7を介して梁添接部材2や柱添接部材3を柱11、梁12の表面に固定するようにしてもよい。   FIG. 6 shows another example of the mounting configuration of the seismic reinforcement apparatus 1 of the present invention. When it is difficult to stably fix the beam attachment member 2 and the column attachment member 3 in the connection with the beam-to-column connection portion, as shown in FIG.
