SEISMIC ISOLATION DEVICE DAMPER AND SEISMIC ISOLATION DEVICE
To provide a seismic isolation device damper that is capable of preventing excessive local deformation of an elastoplastic member constituting the damper, appropriately dispersing plastic deformation to absorb vibration energy throughout the entire damper, and being produced only through simple molding to avoid significant increase in a manufacturing cost.SOLUTION: A damper 1 is made of a rod-like or plate-like elastoplastic member and has a pair of straight parallel line sections 12 and a bent section 11 formed by bending the elastoplastic member to connect one end of each straight parallel line section. The bent section 11 includes a through hole 111 which penetrates the elastoplastic member in a thickness direction.SELECTED DRAWING: Figure 3
【課題】ダンパーを構成する弾塑性部材が局所的に過剰に変形することを防いで、振動エネルギーを吸収するための塑性変形をダンパー全体に適切に分散することができる免震装置用のダンパーを、製造コストの大幅な上昇を回避し得る簡易な成形加工のみによって提供する。【解決手段】棒状又は板状の弾塑性部材からなり、一対の平行な直線部１２と、弾塑性部材が折り曲げられていることによって各々の前記直線部の一方の端部間を結んでいる湾曲部１１によって構成されていて、湾曲部１１に弾塑性部材の厚み方向に貫通する貫通孔１１１が形成されている、ダンパー１とする。【選択図】図３
