EARTHQUAKE-PROOF DAMPER
PROBLEM TO BE SOLVED: To suitably prevent buckling by increasing cross-sectional strength, without increasing weight, cost and a construction procedure.SOLUTION: An earthquake-proof damper 1 is a pipe structure for joining mutual flange parts 7 and 11, by mutually oppositely combining a pair of half-split units 20 formed by adhering a viscoelastic body 5 between half-split metal fittings 4 and 6, by alternately deviatively arranging a plurality of steel plates formed as a half-tubular half-split metal fitting in a lengthwise direction, and in the respective half-split units 20, among the viscoelastic body adhered to the inside half-split metal fitting 4 of an even number, an outside viscoelastic body 5A is extended to the inside metal fitting 14 side up to overlapping with the inside metal fitting 14 in a thickness direction.SELECTED DRAWING: Figure 3
【課題】重量やコスト、施工手順を増加させることなく断面強度を上げて座屈を好適に防止可能とする。【解決手段】制震ダンパー１は、半管状の半割金具とした複数枚の鋼板を、長手方向へ互い違いにずらして配置し、半割金具４，６の間に粘弾性体５を接着して形成される半割ユニット２０を、一対互いに対向させて組み合わせて、フランジ部７，１１同士を接合した管構造であって、各半割ユニット２０において、偶数番の中半割金具４に接着される粘弾性体のうち、外側の粘弾性体５Ａを、厚み方向で中金具１４とオーバーラップするまで中金具１４側へ延設した。【選択図】図３
