STRUCTURAL VIBRATION DAMPER
PROBLEM TO BE SOLVED: To provide a structural vibration damper of which the structure is simplified and which can be manufactured with a dedicated metal molding and facilitates vulcanization adhesion and press-fitting to an elastic rubber, lead or tin cylindrical member.SOLUTION: The structural vibration damper comprises: a cylindrical member 2 which is fixed to one structure; and a rod member 3 which is fixed to the other structure and disposed so as to be relatively displaced between the rod member and the cylindrical member 2. The cylindrical member 2 consists of a plurality of unit cylindrical bodies 4. An outer peripheral part of a ring-shaped earthquake energy absorber 5 made of a ring-shaped elastoplastic rubber, lead or tin with which a hole for inserting the rod member 3 is formed is fixed on an inner wall for each unit cylindrical body 4. A hollow pipe into which the rod member 3 is inserted, for transferring the relative displacement to the earthquake energy absorber is disposed on an inner wall of the ring-shaped earthquake energy absorber 5. The cylindrical member 2 is formed by connecting the unit cylindrical bodies 4 by a connection ring 9 with which a male screw part is formed in an outer peripheral end of the unit cylindrical member 4 and a female screw part is formed in the unit cylindrical body 4. Earthquake energy is absorbed by relatively displacing the cylindrical member 2 and the rod member 3.SELECTED DRAWING: Figure 3
【課題】構造が簡単で、専用金型で製造が可能で、弾性ゴム、鉛又は錫の筒状部材への加硫接着、圧入が容易な構造物用制振ダンパーを提供することを目的とする。【解決手段】一方の構造体に固定される筒状部材２と、他方の構造体に固定され、筒状部材２との間で相対変位可能に配置されロッド部材３を備え、筒状部材２を複数の単位筒状体４で構成し、単位筒状体４毎に内壁にロッド部材３を挿通する穴を形成したリング状の弾塑性ゴム、鉛又は錫からなる地震エネルギー吸収材５の外周部を固定し、リング状の地震エネルギー吸収材５の内壁にロッド部材３が挿通され、相対変位を地震エネルギー吸収材に伝達する中空パイプを配置し、単位筒状体４の外周端部に雄ねじ部を形成し単位筒状体４に雌ねじ部を形成した連結リング９で連結して筒状部材２とし、筒状部材２とロッド部材３の相対変位で地震エネルギーを吸収することを特徴とする。【選択図】図３
