BRIDGE GIRDER SUPPORTING STOPPER AND BRIDGE GIRDER SUPPORTING STRUCTURE INCLUDING THE SAME
PROBLEM TO BE SOLVED: To provide a bridge girder supporting stopper that includes at least a concrete molded body, prevents a horizontal movement of a bridge girder at a time of earthquake, and allows replacement readily after the earthquake, etc.SOLUTION: A bridge girder supporting stopper 3 is arranged to extend in a vertical direction for restricting a horizontal movement of a bridge girder 2 relative to a bridge pier 1 (or a bridge abutment), and includes: an end anchored either on the bridge pier 1 or the bridge girder 2; and the other end fitted on the bridge girder 2 when the end is anchored on the bridge pier 1 or on the bridge pier 1 when the end is anchored on the bridge girder 2, so as to allow the horizontal movement within a specified design range and restrict the movement if an upper limit of the specified range is exceeded. The bridge girder supporting stopper 3 includes a concrete molded body containing a short fiber and having bending strength of 8 N/mmor greater, and a reinforcing member (a reinforcing bar, for example) for reinforcing the concrete molded body.SELECTED DRAWING: Figure 1
【課題】少なくともコンクリート成形体を含む橋桁支持用ストッパーであって、地震の発生時に、橋桁の水平移動を防止することができ、かつ、地震の発生後などにおいて容易に交換が可能な橋桁支持用ストッパーを提供する。【解決手段】橋脚１（もしくは橋台）に対する橋桁２の水平移動を制限するために、橋脚１と橋桁２のいずれかに一端を固着させるとともに、設計上定めた特定の範囲内で水平移動可能でありかつこの特定の範囲の上限を超えると移動が制限されるように、固着の対象が橋脚１である場合には、橋桁２に、固着の対象が橋桁２である場合には、橋脚１に、他端を取り付けて、鉛直方向に延びるように配設して用いるための橋桁支持用ストッパー３。橋桁支持用ストッパー３は、短繊維を含みかつ曲げ強度が８Ｎ／ｍｍ２以上のコンクリート成形体、および、このコンクリート成形体を補強するための補強部材（例えば、補強筋）を含む。【選択図】図１
