EARTHQUAKE-PROOF JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide an earthquake-proof joint structure capable of effectively damping vibration with a simple structure.SOLUTION: In an earthquake-proof joint structure for burying vibration damping means 2 in a concrete structure by providing the vibration damping means in at least one of end parts of a rod-like connection member 1 for connecting a pair of adjacent concrete structures C, the vibration damping means comprises a slipping-out prevention part 4 moving together with the end parts of the connection member, a first rubber elastic deformation part 3 arranged on the inside of the slipping-out prevention part, a second rubber elastic deformation part 7 arranged on the outside, and a rubber cover part 5 for covering the slipping-out prevention part and the first and second elastic deformation parts. The cover part comprises a structure for covering the first elastic deformation part via a first space 6 for allowing deformation of the first elastic deformation part, covering the second elastic deformation part via a second space 8 for allowing deformation of the second elastic deformation part, and movably covering the slipping-out prevention part in the inside-outside direction.SELECTED DRAWING: Figure 5
【課題】簡易構造でありながら効果的に振動を減衰できる耐震継手構造を提供する。【解決手段】隣接する一対のコンクリート構造物Ｃを連結する棒状の連結部材１の端部の少なくとも一方に振動減衰手段２を設け、振動減衰手段をコンクリート構造物内に埋設する耐震継手構造において、振動減衰手段は連結部材の端部と共に移動する抜け止め部４と、抜け止め部の内側に配されたゴム製の第一弾性変形部３と、外側に配されたゴム製の第二弾性変形部７と、抜け止め部及び第一・第二弾性変形部をカバーするゴム製のカバー部５を備え、カバー部は第一弾性変形部を第一弾性変形部の変形を許容する第一空間６を介してカバーし、第二弾性変形部を第二弾性変形部の変形を許容する第二空間８を介してカバーすると共に、抜け止め部を内外方向に移動可能にカバーする構造を具備する。【選択図】図５
