STEEL ROD STOPPER AND STEEL ROD STOPPER FITTING STRUCTURE
To provide a steel rod stopper and a steel rod stopper fitting structure that concentrate damage on an expansion spacing part of the steel rod stopper by fitting a rib to at least part of an embedding part of the steel rod stopper, to make it possible to suppress damage of concrete of a structure in which the embedding part of the steel rod stopper is embedded and easily and rapidly perform work of recovering the structure.SOLUTION: A steel rod stopper composed of a round steel bar 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 a rib is fitted to an outer peripheral surface of at least part of the embedding parts.SELECTED DRAWING: Figure 5
【課題】鋼棒ストッパーの埋込部の少なくとも一部にリブを取付けることによって、損傷を鋼棒ストッパーの遊間部に集中させ、鋼棒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鋼棒ストッパー及び鋼棒ストッパー取付構造を提供する。【解決手段】下部工に少なくとも下端が埋込まれ、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丸鋼棒から成る鋼棒ストッパーであって、下部工と上部工との間の空隙に露出する遊間部と、下部工及び上部工に埋込まれる埋込部とを備え、埋込部の少なくとも一部の外周面にリブが取付けられている。【選択図】図５
