BRIDGE FALL PREVENTION DEVICE
To provide an inexpensive bridge fall prevention device having readiness, no temperature dependency, etc., high impact absorption performance, easy maintenance and management, and simple structure.SOLUTION: A bridge fall prevention device S1 is provided with a first support member 10 to be attached to a bridge abutment P (lower structure), and a second support member 20 to be attached to a bridge girder G (upper structure) provided opposite to the first support member 10. The first support member 10 and the second support member 20 are rotatable to a PC steel bar 31 and are slidably and separably joined in the horizontal direction. An interposing plate 30 (interposing member) is provided between the first support member 10 and the second support member 20 in a state in which clamping force is imparted by the PC steel bar 31.SELECTED DRAWING: Figure 1
【課題】 即応性を備え、温度依存性等を有さず、撃吸収性能が高く、維持管理が容易であり、簡易な構造かつ安価な落橋防止装置を提供する。【解決手段】橋台Ｐ（下部構造）に取り付けるための第１支持部材１０と、第１支持部材１０に対向して設けられる、橋桁Ｇ（上部構造）に取り付けるための第２支持部材２０と、を有し、第１支持部材１０と第２支持部材２０は、ＰＣ鋼棒３１に対して回動自在であり、水平方向に、摺動可能かつ接離可能に接合されており、第１支持部材１０と第２支持部材２０との間に、介装板３０（介装部材）がＰＣ鋼棒３１により、挟着力を付与された状態で設けられている落橋防止装置Ｓ１とした。【選択図】 図１
