Description

この発明は、構造物の骨組みに組み込まれ、地震等の際に振動エネルギーを吸収して振動を減衰させる座屈拘束ブレースに関する。   The present invention relates to a buckling-restrained brace that is incorporated in a framework of a structure and absorbs vibration energy and attenuates vibration in the event of an earthquake or the like.

この種の従来の座屈拘束ブレースでは、芯材の周囲に配置する拘束材を、鋼材とコンクリートの合成構造としているものが多い。拘束材に溝形鋼などの鋼材を用いたものも提案されているが（例えば、特許文献１，２）、これらは、いずれも他の鋼材・コンクリート合成構造の拘束材を用いた座屈拘束ブレースと同じく、芯材が拘束材で覆われている。
特開平１１−１５９０１０号公報 特開２００５−１９４７９４号公報 In this type of conventional buckling restraint brace, the restraint material arranged around the core is often a composite structure of steel and concrete. There are also proposals using steel materials such as channel steel as restraint materials (for example, Patent Documents 1 and 2), but these are buckling restraints using restraints of other steel materials and concrete composite structures. Like the brace, the core is covered with a restraining material.
Japanese Patent Laid-Open No. 11-159010 JP 2005-194794 A

従来の拘束材を鋼材とコンクリートの合成構造とした座屈拘束ブレースは、製作ならびに品質管理が難しい。
また、従来の座屈拘束ブレースは、いずれも芯材が拘束材で覆われていて、外部から芯材の状態を目視できない。そのため、製作時の品質管理が困難であるばかりか、地震を受けた後に芯材の状況を確認できない。そのため、座屈拘束ブレースの交換の要否を判断することが困難である。 It is difficult to manufacture and control the quality of buckling-restrained braces that are made of a composite structure of steel and concrete.
Moreover, as for the conventional buckling restraint brace, the core material is covered with the restraint material and the state of the core material cannot be visually observed from the outside. Therefore, quality control at the time of production is difficult, and the condition of the core material cannot be confirmed after the earthquake. For this reason, it is difficult to determine whether or not the buckling restraint brace needs to be replaced.

この発明の目的は、製作および品質管理が容易で、また地震を受けた後のブレース交換の要否の判断が可能な座屈拘束ブレースを提供することである。   An object of the present invention is to provide a buckling-restrained brace that is easy to manufacture and quality control and that can determine whether or not it is necessary to replace the brace after an earthquake.

この発明の座屈拘束ブレースは、芯材と、この芯材の両面に沿って配置された一対の拘束材とを有する座屈拘束ブレースにおいて、前記芯材が帯板状の鋼板からなり、前記一対の拘束材が溝形鋼であってウェブ部を芯材側に向けて配置され、前記芯材は長手方向に沿って延びるスリットを有し、前記両拘束材は前記ウェブ部における長手方向の複数箇所にボルト挿通孔が設けられ、両側の拘束材の複数箇所のボルト挿通孔と前記芯材のスリットとに渡ってそれぞれ貫通した複数のボルトにより、前記芯材と前記一対の拘束材とが一体に結合され、前記芯材と拘束材との重なり面に滑り材が介在し、前記芯材が前記一対の拘束材の間において外部に露出していることを特徴とする。
この構成によると、芯材とその両側の溝形鋼からなる拘束材とを、これら拘束材のボルト挿通孔と芯材のスリットとに渡って貫通したボルトによる乾式接合で一体に結合しているので、製作が容易で品質も安定したものとなる。また、溶接部がほとんどなく、外部から見えず、シンプルな外観とすることができる。また、拘束材に溝形鋼を用いたため、材料調達が容易で、コストも削減できる。
特に、芯材が一対の拘束材の間において外部に露出しているので、芯材を外部から目視できて、製作時の品質管理が容易であり、また地震後に芯材の状況を確認して、ブレース交換の要否を判断することができる。
また、芯材と拘束材との重なり面に滑り材を介在させたので、芯材の軸力が拘束材に伝播するのを防止でき、それだけ強度向上が可能となる。 The buckling restraint brace of the present invention is a buckling restraint brace having a core material and a pair of restraint materials arranged along both surfaces of the core material, wherein the core material is a strip-shaped steel plate, A pair of restraint materials is channel steel and is arranged with the web portion facing the core material side, the core material has a slit extending along the longitudinal direction, and both the restraint materials are arranged in the longitudinal direction of the web portion. Bolt insertion holes are provided at a plurality of locations, and the core member and the pair of restraint members are formed by a plurality of bolts penetrating through the bolt insertion holes at a plurality of locations on both sides and the slits of the core member. It is combined integrally, a sliding material is interposed on the overlapping surface of the core material and the restraint material, and the core material is exposed to the outside between the pair of restraint materials.
According to this configuration, the core material and the restraint material made of channel steel on both sides of the core material are integrally coupled by dry bonding using bolts that penetrate through the bolt insertion holes of the restraint material and the slits of the core material. Therefore, it is easy to manufacture and the quality is stable. Moreover, there is almost no welded part, and it cannot be seen from the outside, and a simple appearance can be achieved. In addition, since grooved steel is used as the restraining material, material procurement is easy and costs can be reduced.
In particular, since the core material is exposed to the outside between a pair of constraining materials, the core material can be visually observed from the outside, quality control at the time of production is easy, and the condition of the core material can be confirmed after an earthquake. The necessity of brace replacement can be determined.
Further, since the slip material is interposed on the overlapping surface of the core material and the restraint material, it is possible to prevent the axial force of the core material from propagating to the restraint material, and the strength can be improved accordingly.

この発明において、前記芯材のスリットが、芯材の長手方向に並んで複数設けられて隣合うスリット間に、芯材のスリット両側の部分を互いに繋ぐ繋ぎ部を有するものとしても良い。このように繋ぎ部を設けた場合、芯材の強軸方向の座屈を防止できる。   In the present invention, a plurality of slits of the core material may be provided side by side in the longitudinal direction of the core material, and between the adjacent slits, there may be a connecting portion that connects portions on both sides of the slit of the core material. When the connecting portion is provided in this way, the core material can be prevented from buckling in the strong axis direction.

この発明において、前記芯材の１箇所の繋ぎ部に、ずれ防止孔を有し、前記複数のボルトのうちの１本のボルトは、前記スリットに挿通させる代わりに、前記ずれ防止孔に挿通させるものとしても良い。このように、スリットの代わりにずれ防止孔を設けてボルトを挿通させた場合、芯材に対する拘束材の位置関係を一定に保持して、拘束材による芯材に対する変形抑制作用を安定化させることができる。   In this invention, it has a slip prevention hole in one connecting part of the core material, and one bolt of the plurality of bolts is inserted into the slip prevention hole instead of being inserted into the slit. It is good as a thing. In this way, when a bolt is inserted with a slip prevention hole provided in place of the slit, the positional relationship of the restraint material with respect to the core material is kept constant, and the deformation suppressing effect on the core material by the restraint material is stabilized. Can do.

Further, as shown in FIG. 1C, a sliding material 10 is interposed on the overlapping surface of the core material 2 and the restraining material 3. The sliding material 10 is made of a plate member made of rubber or synthetic resin, or a viscoelastic member such as asphalt. The sliding material 10 is a member that facilitates relative sliding between the core material 2 and the restraining material 3. Even if the sliding material 10 facilitates the relative sliding due to deformation of the sliding material 10, the frictional resistance of the contact surface is also reduced. The relative sliding may be facilitated by reducing the amount.

芯材２の両端部２Ａは、図１（Ａ），（Ｂ）のように連結プレート１１を介して、構造物側の継手部材に連結される。同図の場合、構造物側の継手部材は前記芯材２の両端部２Ａと同じＨ形の断面形状であり、この継手部材の上下のフランジ部（図示せず）の表裏面と芯材端部２Ａの上下のフランジ部２ａの表裏面とに沿わせた各連結プレート１１をボルト１２で前記各フランジ部に締結すると共に、前記継手部材のウェブ部（図示せず）の両面と芯材端部２Ａのウェブ部２ｂの両面とに沿わせた各連結プレート１１をボルト１２で前記各ウェブ部に締結することにより、これらの連結プレート１１を介して座屈拘束ブレース１が構造物側の継手部材に連結される。ボルト１２による前記連結プレート１１の締結には、芯材端部２Ａのボルト挿通孔７（図２）が使用される。   Both end portions 2A of the core material 2 are connected to a joint member on the structure side via a connection plate 11 as shown in FIGS. 1 (A) and 1 (B). In the case of the figure, the joint member on the structure side has the same H-shaped cross section as the two end portions 2A of the core member 2, and the front and back surfaces of the upper and lower flange portions (not shown) of the core member and the core member ends. The connection plates 11 along the front and back surfaces of the upper and lower flange portions 2a of the portion 2A are fastened to the flange portions with bolts 12, and both surfaces of the web portion (not shown) of the joint member and the core end By fastening the connecting plates 11 along the both surfaces of the web portion 2b of the portion 2A to the web portions with bolts 12, the buckling-restraining brace 1 is connected to the structure side joint via the connecting plates 11.
