CONNECTOR FOR WIDENING AND ANCHORAGE METHOD
To provide a connector for widening capable of being connected with an existing anchorage of an existing PC structure which does not include a connection structure with the connector in advance, and to provide an anchorage method.SOLUTION: A connector for widening is connected to an existing PC steel material of an existing PC structure and a widening PC steel material which is laid in a widening portion respectively, and for re-straining the existing PC steel material according to the straining of the widening PC steel material which is anchored and fixed at the widening portion. The connector for widening includes: a primary side connection unit that has a sleeve member for surrounding a wedge anchorage of the existing PC steel material exposed from the existing PC structure, and a wedge member inserted between the wedge anchorage and the sleeve member; a secondary side connection unit to which one end of the widening PC steel material is fixed; and a connection member for connecting the primary side connection unit and the secondary side connection unit.SELECTED DRAWING: Figure 3
【課題】予め接続具との接続構造を備えていない既設ＰＣ構造体の既設定着具と接続可能な拡幅用接続具及び定着方法を提供する。【解決手段】本発明は、既設ＰＣ構造体の既設ＰＣ鋼材と拡幅部分に敷設される拡幅ＰＣ鋼材とにそれぞれ接続し、拡幅部分において定着固定される拡幅ＰＣ鋼材の緊張に伴って既設ＰＣ鋼材を再緊張させるための拡幅用接続具である。拡幅用接続具は、既設ＰＣ構造体から露出した既設ＰＣ鋼材のくさび定着具を取り囲むスリーブ部材と、くさび定着具とスリーブ部材との間に挿入されるウェッジ部材とを有する１次側接続ユニットと、拡幅ＰＣ鋼材の一端が固定される２次側接続ユニットと、１次側接続ユニットと２次側接続ユニットとを連結する連結部材と、を有する。【選択図】図３
