STOPPER AND STOPPER FITTING STRUCTURE
To concentrate damage on an expansion spacing part of a stopper by making at least part of an embedding part of the stopper be made of a double filled steel tube, to make it possible to suppress damage of concrete of a structure in which the embedding part of the stopper is embedded and easily and rapidly perform work of recovering the structure.SOLUTION: A stopper composed of a filled steel tube having a lower end that at least is to be embedded in a substructure and an upper end that at least is to be embedded in a superstructure placed on the substructure comprises: an expansion spacing part exposed to a gap between the substructure and the superstructure; and embedding parts to be embedded in the substructure and the superstructure, where at least part of the embedding parts is a double filled steel tube.SELECTED DRAWING: Figure 5
【課題】ストッパーの埋込部の少なくとも一部を二重充填鋼管にすることによって、損傷をストッパーの遊間部に集中させ、ストッパーの埋込部が埋込まれた構造物のコンクリートの損傷を抑制することができ、構造物の復旧作業を容易に、かつ、迅速に行うことができるようにする。【解決手段】下部工に少なくとも下端が埋込まれ、前記下部工の上に載置された上部工に少なくとも上端が埋込まれる充填鋼管から成るストッパーであって、前記下部工と上部工との間の空隙に露出する遊間部と、前記下部工及び上部工に埋込まれる埋込部とを備え、該埋込部の少なくとも一部が二重充填鋼管である。【選択図】図５
