EARTHQUAKE PROOF DESORPTION PREVENTION JOINT
PROBLEM TO BE SOLVED: To provide a desorption prevention joint capable of resisting against a thrust force at a normal time and achieving an earthquake proof performance at the time of occurrence of earthquakes.SOLUTION: This invention relates to an earthquake desorption prevention joint in which an insertion part 37 comprises an earthquake desorption resisting part 42 having stopper metal fittings 41, 41...movably fitted into a plurality of respective earthquake proof desorption resisting stopper fitting parts 40, 40 faced in a radial direction in a desired peripheral pitch at the outer peripheral part of the extremity end in an inserting direction, and a thrust resisting part 45 arranged at a distance on the near side in an inserting direction of the earthquake desorption resisting part 42, having stopper metal fittings 44 movably fitted into a plurality of respective thrust resisting stopper fitting parts 43, 43... faced in a radial direction at a desired peripheral pitch. The stopper metal fittings 44, 44...of the thrust resisting part 45 are engaged with a pull-out prevention convex part 39.SELECTED DRAWING: Figure 3
【課題】通常時にはスラスト力に対抗でき、地震動発生時には耐震性能を発揮できる離脱防止継手の提供。【解決手段】差し込み部３７には、差し込み方向先端側の外周部に所望の周方向ピッチで半径方向に向けた複数の耐震離脱抵抗用ストッパー嵌合部４０，４０...にそれぞれストッパー金具４１，４１...を移動可能に嵌合させてなる耐震離脱抵抗部４２と、耐震離脱抵抗部４２の差し込み方向手前側に距離を置いて配置され、所望の周方向ピッチで半径方向に向けた複数のスラスト抵抗用ストッパー嵌合部４３，４３...にそれぞれストッパー金具４４を移動可能に嵌合させてなるスラスト抵抗部４５とを備え、スラスト抵抗部４５のストッパー金具４４，４４...を抜け出し防止凸部３９と係合させている耐震離脱防止継手。【選択図】図３
