EARTHQUAKE STRENGTHENING DEVICE FOR EXISTING BUILDING
To provide an earthquake strengthening device for an existing building which can be compactly installed in a column-beam connection portion of an existing building and which can effectively exhibit strengthening effect to a column-beam connection portion and attenuation effect to a damper.SOLUTION: Beam splice members 2 in horizontal two directions extending along crossing beams 12 in two directions of a column-beam connection portion; a column splice member 3 extending upwardly or downwardly from an intersection of the beam splice members 2 in two directions; a rod shaped horizontal damper 4 connecting tip portions of the beam splice members 2 in two directions; and two rod shaped diagonal dampers 5 connecting tip portions of the column splice member 3 with tip portions of the beam splice members 2 in two directions are connected in a three-dimensional truss shape so as to form six sides of a substantially trigonal pyramid shape. The three-dimensional truss shape resists vibration of the column-beam connection portion in an earthquake. Against vibration larger than a prescribed scale of the column-beam connection portion, the horizontal damper 4 and the diagonal dampers 5 absorb vibration energy.SELECTED DRAWING: Figure 1
【課題】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。【解決手段】柱梁接合部の交差する２方向の梁１２に沿って延びる水平２方向の梁添接部材２と、これら２方向の梁添接部材２の交点から上方または下方に延びる柱添接部材３と、２方向の梁添接部材２の先端部間をつなぐ棒状の水平ダンパー４と、柱添接部材３の先端部と２方向の梁添接部材２の先端部間をつなぐ２本の棒状の斜めダンパー５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いる。立体トラス形状によって柱梁接合部の地震時の振動に抵抗し、柱梁接合部の所定以上の振動に対しては水平ダンパー４および斜めダンパー５が振動エネルギーを吸収する。【選択図】図１
