特開２００６−２８３３７４号公報 Various damping panels have been provided in the past to give the building a damping function, but these damping panels require a large wall area for installation, and have a low resistance to wind and a load-bearing panel. There is a problem that does not function as.
JP 2006-283374 A

本発明は、上記のような問題点に鑑み、耐震性能と耐力性能の両方を効果的に発揮することができ、しかも、設置に大きな壁面積を必要としない制震耐震構造を提供することを課題とする。   In view of the above problems, the present invention provides a seismic and earthquake-resistant structure that can effectively exhibit both seismic performance and proof performance, and that does not require a large wall area for installation. Let it be an issue.

上記の課題は、間柱が隣接状態に配置され、一方の間柱の対向面部に縦長のスリットが設けられると共に、もう一方の間柱の対向面部に、前記スリット内に突出するプレート部が設けられ、
スリットの高さ寸法はプレート部の高さ寸法よりも大きく、前記もう一方の間柱には、プレート部の上下両側において、スリットを横断する制震耐震材が設けられ、各制震耐震材は、プレート部と当接して耐震性能を発揮すると共に、プレート部によって変形及び／又は破断して制震性能を発揮するようになされていることを特徴とする間柱制震耐震構造によって解決される（第１発明）。なお、隣接する各間柱の上下の端部は、上下の梁に対して、ピン接合されているとよい。 The above problem is that the studs are arranged adjacent to each other, a vertically long slit is provided on the facing surface portion of one of the studs, and a plate portion protruding into the slit is provided on the facing surface portion of the other stud.
The height dimension of the slit is larger than the height dimension of the plate part, and the other studs are provided with seismic control materials that cross the slits on both the upper and lower sides of the plate part. This is solved by the inter-column seismic seismic structure characterized in that it is in contact with the plate portion and exhibits seismic performance, and is deformed and / or broken by the plate portion to exhibit seismic performance. 1 invention). Note that the upper and lower ends of each adjacent stud are preferably pin-joined to the upper and lower beams.

この構造では、一方の間柱の対向面部に縦長のスリットが設けられると共に、もう一方の間柱の対向面部に、前記スリット内に突出するプレート部が設けられという構成において、前記もう一方の間柱に、プレート部の上下両側において、スリットを横断する制震耐震材が設けられ、プレート部が制震耐震材に当接することで耐震性能が発揮され、プレート部によって制震耐震材が変形及び／又は破断して制震性能が発揮されるようになされているので、耐震性能と制震性能を地震等の大きさに応じて効果的に発揮することができる。   In this structure, in the configuration in which the vertically long slit is provided in the facing surface portion of one of the intermediate pillars, and the plate portion protruding into the slit is provided in the opposing surface portion of the other intermediate pillar, Anti-seismic material that crosses the slit is provided on both the upper and lower sides of the plate part, and the plate part abuts against the anti-seismic anti-seismic material, and the anti-seismic performance is exhibited. Therefore, the seismic performance can be effectively exhibited according to the magnitude of the earthquake or the like.

しかも、隣接状態に配置した間柱間に、スリットとプレート部と制震耐震材とによる制震耐震機構を組み込んだ構成であるので、設置に大きな壁面積を必要としない。特に、一方の間柱のプレート部をもう一方の間柱のスリット内に突出させた構造であることにより、隣接する間柱の間隔寸法を小さくすることができて、設置のための壁面積を非常に小さなものにすることができる。   And since it is the structure which incorporated the seismic control mechanism by the slit, the plate part, and the seismic control material between the studs arrange | positioned adjacently, a big wall area is not required for installation. In particular, the structure in which the plate portion of one of the studs protrudes into the slit of the other stud, so that the distance between adjacent studs can be reduced, and the wall area for installation is very small. Can be a thing.

第１発明において、制震耐震材が低降伏点鋼からなる場合（第２発明）は、そのような耐震性能と制震性能を容易にしかも効果的に発揮させることができる。   In the first invention, when the seismic control material is made of low yield point steel (second invention), such seismic performance and seismic performance can be easily and effectively exhibited.

第１，２発明において、前記プレート部と上下の制震耐震材との間に隙間が設けられ、該隙間による震動を制震する一次制震機構が備えられているとよい（第３発明）。この場合は、低降伏点鋼に制震作用を行わせる地震よりも小さな地震に対して、一次制震機構が制震作用を行うので、そのような地震に対して効果的な制震性能を発揮することができる。   In the first and second inventions, a gap may be provided between the plate portion and the upper and lower seismic control materials, and a primary seismic control mechanism for controlling the vibration caused by the gap may be provided (third invention). . In this case, the primary seismic control mechanism performs seismic control for earthquakes smaller than those that cause low yield point steel to perform seismic control. It can be demonstrated.

第１〜第３発明において、前記制震耐震材がプレート部によって変形及び／又は破断し、プレート部がスリットの端部に当接することで二次的な耐震性能が発揮されるようになされているのもよい（第４発明）。この場合は、制震耐震材の変形及び／又は破断による二次的な制震作用との組み合わせで、プレート部がスリットの端部に当接して建物の倒壊を効果的に防ぐことができる。   In the first to third inventions, the seismic control material is deformed and / or broken by the plate portion, and the plate portion comes into contact with the end of the slit so that secondary seismic performance is exhibited. (4th invention). In this case, the plate portion can abut against the end portion of the slit and effectively prevent the building from collapsing in combination with the secondary seismic control action by deformation and / or fracture of the seismic control material.

また、上記の課題は、間柱が隣接状態に配置され、一方の間柱の対向面部に縦長のスリットが設けられると共に、もう一方の間柱の対向面部に、前記スリット内に突出するプレート部が設けられ、
スリットの高さ寸法はプレート部の高さ寸法よりも大きく、前記もう一方の間柱には、プレート部の上下両側において、スリットを横断する耐震材またはスリットの端部が設けられ、各耐震材又はスリットの端部は、プレート部と当接して耐震性能を発揮するようになされており、かつ、
前記プレート部と上下の耐震材との間に隙間が設けられ、該隙間による震動を制震する制震機構が備えられていることを特徴とする間柱制震耐震構造によって解決される。 In addition, the above problem is that the studs are arranged adjacent to each other, a vertically long slit is provided on the facing surface portion of one of the studs, and a plate portion protruding into the slit is provided on the facing surface portion of the other stud. ,
The height dimension of the slit is larger than the height dimension of the plate portion, and the other intermediate column is provided with an earthquake-resistant material or an end portion of the slit across the slit on both the upper and lower sides of the plate portion. The end of the slit is in contact with the plate and is designed to exhibit seismic performance, and
A space is provided between the plate portion and the upper and lower earthquake-resistant materials, and a space-damping seismic structure is provided that includes a seismic control mechanism that controls the vibration caused by the space.

この間柱制震耐震構造では、地震に対して制震機構が制震作用を行うので、そのような地震に対して効果的な制震性能を発揮することができ、それよりも大きな地震では、プレート部が耐震材又はスリットの端部に当接することで耐震性能が発揮されるので、耐震性能と制震性能を地震等の大きさに応じて効果的に発揮することができる。しかも、隣接状態に配置した間柱間に、スリットとプレート部とによる耐震機構を組み込んだ構成であるので、設置に大きな壁面積を必要としない。   In this inter-column seismic control structure, the seismic control mechanism performs seismic control against earthquakes, so that effective seismic performance can be demonstrated against such earthquakes. Since the plate portion abuts against the seismic material or the end of the slit, the seismic performance is exhibited, so that the seismic performance and the seismic performance can be effectively exhibited according to the magnitude of the earthquake or the like. And since it is the structure which incorporated the earthquake-resistant mechanism by a slit and a plate part between the studs arrange | positioned in an adjacent state, a big wall area is not required for installation.

本発明は、以上のとおりのものであるから、耐震性能と耐力性能の両方を効果的に発揮することができ、しかも、設置に大きな壁面積を必要としない。   Since the present invention is as described above, it is possible to effectively exhibit both seismic performance and proof performance, and a large wall area is not required for installation.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１及び図２に示す実施形態の間柱制震耐震構造において、１は間柱制震耐震構造体、２は階下の鋼製梁、３は階上の鋼製梁である。   In the embodiment shown in FIGS. 1 and 2, 1 is an inter-column vibration control structure, 2 is a steel beam on the lower level, and 3 is a steel beam on the lower level.

該間柱制震耐震構造体１は、上下の鋼製ベースプレート部４，４間に、角形鋼管材などの鋼材からなる間柱５，５が隣接状態に配置され、各間柱５，５の上下の端部が各ベースプレート部４，４にピン接合６されたもので、一方の間柱５の対向面部の高さ方向の中間部には縦長のスリット７が設けられ、もう一方の間柱５の対向面部には、スリット７内に突出する鋼製プレート部８が溶接などで取り付けられている。そして、スリット７の高さ寸法は、プレート部８の高さ寸法よりも大きく設定されていて、前記もう一方の間柱５には、プレート部８の上下両側において、スリット７を横断する、低降伏点鋼からなる制震耐震材９，９が取り付けられ、各制震耐震材９，９は、プレート部８と当接して耐震性能を発揮し、プレート部８によって変形及び／又は破断して制震性能を発揮するようになされている。   The inter-column seismic control structure 1 includes inter-columns 5 and 5 made of steel such as square steel pipes adjacent to each other between upper and lower steel base plate portions 4 and 4, and upper and lower ends of the inter-columns 5 and 5. The portion is pin-joined 6 to each of the base plate portions 4, 4, and a vertically long slit 7 is provided in the intermediate portion in the height direction of the facing surface portion of one of the intermediate pillars 5. The steel plate part 8 which protrudes in the slit 7 is attached by welding. The height dimension of the slit 7 is set larger than the height dimension of the plate portion 8, and the other intermediate pillar 5 has a low yield crossing the slit 7 on both the upper and lower sides of the plate portion 8. Anti-seismic seismic materials 9 and 9 made of point steel are attached, and each seismic anti-seismic material 9 and 9 abuts against the plate portion 8 and exhibits seismic performance. It is designed to exhibit seismic performance.

また、本実施形態では、制震耐震材９がプレート部８によって変形及び／又は破断し、プレート部８がスリット７の端部７ａ，７ａに当接することで、制震耐震材９による耐震制震作用が行われた後の二次的な耐震性能が発揮されるようになされている。   Further, in this embodiment, the vibration control material 9 is deformed and / or broken by the plate portion 8, and the plate portion 8 abuts against the end portions 7 a and 7 a of the slit 7. The secondary seismic performance after the seismic action is performed.

更に、本実施形態の間柱制震耐震構造体１では、プレート部８と上下の制震耐震材９，９との間に隙間１０，１０が設けられると共に、該隙間１０，１０による震動を制震する一次制震機構１１が設けられている。該一次制震機構１１は、上下のベースプレート部４，４と、隣接間柱５，５とをつなぐピン接合部６…のそれぞれに粘弾性体１１ａ…を組み込んて構成したもので、各ピン接合部６…が回転変位動作を行うと、各粘弾性体１１ａ…がねじれせん断変形をしてエネルギーを吸収し、制震耐震材９による制震作用が行われる前の一次的な制震作用を行うようにされている。   Furthermore, in the middle column damping earthquake-resistant structure 1 of the present embodiment, gaps 10 and 10 are provided between the plate portion 8 and the upper and lower damping earthquake-resistant materials 9 and 9, and vibration caused by the gaps 10 and 10 is controlled. A seismic primary damping mechanism 11 is provided.

Perform a rotational displacement operation, each viscoelastic body 11 a undergoes torsional shear deformation and absorbs energy, and performs a primary seismic control before the seismic control material 9 is controlled. Has been.

そして、間柱制震耐震構造は、上記の間柱制震耐震構造体１の下ベースプレート部４を階下の鋼製梁２に固着すると共に、上ベースプレート部４を階上の鋼製梁３に固着することにより形成される。   In the inter-column vibration control structure, the lower base plate portion 4 is fixed to the downstairs steel beam 2 and the upper base plate portion 4 is fixed to the upper steel beam 3. Is formed.

上記の間柱制震耐震構造では、中地震時には、図３に示すように、各ピン接合部６…が回転変位動作を行い、各粘弾性体１１ａ…がねじれせん断変形をしてエネルギーを吸収することで制震作用が行われる。   In the above-described columnar seismic control structure, during a middle earthquake, as shown in FIG. 3, each pin joint 6 performs a rotational displacement operation, and each viscoelastic body 11a ... twists and shears to absorb energy. Therefore, the vibration control effect is performed.

また、暴風や大地震時には、図４に示すように、プレート部８が制震耐震材９に当接し、制震耐震材９がそれに抵抗することで、耐震性能が発揮される。   Further, in the case of a storm or a large earthquake, as shown in FIG. 4, the plate portion 8 abuts against the vibration control material 9 and the vibration control material 9 resists it, thereby exhibiting the earthquake resistance.

そして、想定外の大地震時には、各粘弾性体１１ａ…がねじれせん断変形をしてエネルギーを吸収すると共に、プレート部８が制震耐震材９を変形及び／又は破断して制震性能が発揮され、プレート部８がスリット７の端部に当接することにより、建物の倒壊が阻止される。特に、制震耐震材９が変形及び／又は破断をしてエネルギーを吸収して抵抗し、また、各粘弾性体１１ａ…がねじれせん断変形をしてエネルギーを吸収した後、プレート部８がスリット７の端部に当接するようになされているので、建物の倒壊を効果的に防ぐことができる。   In the event of an unexpected large earthquake, each viscoelastic body 11a ... twists and shears to absorb energy, and the plate portion 8 deforms and / or breaks the vibration control material 9 to exhibit vibration control performance. Then, the plate portion 8 abuts against the end portion of the slit 7 to prevent the building from collapsing. In particular, after the seismic anti-seismic material 9 deforms and / or breaks and absorbs energy to resist, and each viscoelastic body 11a ... absorbs energy by twisting shear deformation, the plate portion 8 is slit. Since it is made to contact | abut to the edge part of 7, the collapse of a building can be prevented effectively.

このように、上記の間柱制震耐震構造によれば、耐震性能と制震性能を地震等の大きさに応じて効果的に発揮することができ、しかも、隣接状態に配置した間柱５，５間に、スリット７とプレート部８と制震耐震材９，９とによる制震耐震機構を組み込んだ構成であるので、設置に大きな壁面積を必要としない。   As described above, according to the above-described inter-column seismic control structure, the seismic performance and the seismic control performance can be effectively exhibited according to the magnitude of the earthquake and the like, and the inter-columns 5 and 5 arranged in the adjacent state are provided. Since it is the structure which incorporated the earthquake-proof earthquake-resistant mechanism by the slit 7, the plate part 8, and the vibration-proof earthquake-resistant material 9 and 9, in the middle, a big wall area is not required for installation.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、上記の実施形態では、建物への組込みを容易にするため、間柱制震耐震構造体１の上下のベースプレート部４，４を上下の梁２，３に固着状態に取り付けることで間柱制震耐震構造が構成されるようになされている場合を示したが、そのような上下のベースプレート部４，４によらずに、上下の梁２，３間に間柱５，５を組み込んで間柱制震耐震構造を構成するようにしてもよい。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, in order to facilitate incorporation into a building, the upper and lower base plate portions 4 and 4 of the inter-column vibration control structure 1 are attached to the upper and lower beams 2 and 3 in a fixed state so that the inter-column vibration control is achieved. Although the case where the seismic structure is constructed is shown, the studs 5 and 5 are incorporated between the upper and lower beams 2 and 3 without using the upper and lower base plate parts 4 and 4 so as to control the studs. You may make it comprise an earthquake-resistant structure.

また、上記の実施形態では、一次制震機構として、間柱５，５と梁２，３とのピン接合部６…に粘弾性体１１ａ…を組み込んだものを採用したが、隣り合う間柱間に解説した粘弾性体をせん断変形させることで一次的な制震が行われるようにしてもよいし、プレート部と上下の制震耐震材との間の隙間をなくすと共に、一次制震機構を省略した構造に構成されていてもよい。   Moreover, in said embodiment, although what integrated the viscoelastic body 11a ... into the pin junction part 6 ... of the pillars 5 and 5 and the beams 2 and 3 as a primary damping mechanism was employ | adopted, between adjacent studs. The viscoelastic body described may be subjected to shear deformation so that primary vibration control is performed, and the gap between the plate part and the upper and lower vibration control materials is eliminated, and the primary vibration control mechanism is omitted. It may be configured in such a structure.

It may be.

また、上記の実施形態において、制震耐震材９，９を耐震材で構成したり、制震耐震材９，９を省略した構造とするのもよい。それらの場合でも、地震に対して制震機構１１…が制震作用を行うので、そのような地震に対して効果的な制震性能を発揮することができ、それよりも大きな地震では、プレート部８が耐震材９に当接するかスリット７の端部７ａに当接することで耐震性能が発揮されるので、耐震性能と制震性能を地震等の大きさに応じて効果的に発揮することができる。   Moreover, in said embodiment, it is good also as a structure which comprised the seismic control material 9 and 9 with a seismic material, or abbreviate | omitted the seismic control material 9 and 9. Even in those cases, since the vibration control mechanism 11 performs the vibration control action against the earthquake, it is possible to exert effective vibration control performance against such an earthquake. Since the seismic performance is exhibited when the portion 8 abuts against the seismic material 9 or the end 7a of the slit 7, the seismic performance and the seismic performance are effectively exhibited according to the magnitude of the earthquake or the like.
