Zusammenfassung:The present invention relates to a shear key installed between the upper and lower structures of a bridge. More particularly, the present invention relates to a shear key for a bridge capable of measuring negative reaction force resistance and displacement. According to the present invention, the shear key for a bridge comprises: an upper plate (100) provided with an upper guide protrusion (110) including an extension part (112); a lower plate (200) provided below the upper plate (100) and fixed to a lower structure of the bridge; and a pair of lower guide protrusions (300) provided between the upper plate (100) and the lower plate (200) and including an upper member (330). A portion of the upper member (330) is located vertically above the expansion part (112) to resist negative reaction force. 본 발명은, 교량의 상부구조물과 하부구조물 사이에 설치되는 전단키에 있어서, 확장부(112)를 포함하는 상부가이드돌기(110)가 구비되는 상부판(100); 상기 상부판(100)의 하방에 구비되고, 교량 하부구조물에 고정되는 하부판(200); 상기 상부판(100)과 하부판(200) 사이에 구비되고, 상부부재(330)를 포함하는 한 쌍의 하부가이드돌기(300)를 포함하되, 상기 상부부재(330)의 일부가 상기 확장부(112)의 연직 상방에 위치하여, 부반력에 저항하는 것을 특징으로 하는 부반력저항 및 변위측정이 가능한 교량용 전단키에 관한 것이다.
