BRIDGE FALL PREVENTION BLOCK
To provide a bridge fall prevention block capable of preventing the fall of an upper structure supported by a lower structure by being locked to a part of the upper structure without increasing the number of installations or enlarging the size.SOLUTION: A bridge fall prevention block 10, which is attached to a bridge abutment 2 and prevents an upper structure 3 from falling off by locking a locking beam 31 supported on an abutment 2, has a fixing part 11 that is fixed along the upper part of an abutment front surface 21 of the bridge abutment 2, an extension part 12 extending from the fixing part 11 in a bridge axial direction L and a locking projection part 13 projecting from the extension part 12 toward the upper structure 3 and locked to the upper structure 3, and formed in a hook shape; and the fixing part 11, the extension part 12 and the locking projection part 13 are integrally constituted by high-strength fiber reinforced mortar and curved steel reinforced fiber mixed in the high-strength fiber reinforced mortar.SELECTED DRAWING: Figure 2
【課題】設置数を増加したり、大型化することなく、上部構造物の一部に係止して、下部構造物に支承された上部構造物の脱落を防止できる落橋防止ブロックを提供することを目的とする。【解決手段】橋台２に取付けられ、橋台２に支承された係止ビーム３１に係止して、上部構造３の脱落を防止する落橋防止ブロック１０を、橋台２における橋台前面２１の上方に沿って固定される固定部１１と、固定部１１から、橋軸方向Ｌに延出された延出部１２と、延出部１２から上部構造３に向かって突出し、上部構造３に係止する係止突出部１３とを有するとともに、鉤型形状に形成し、固定部１１、延出部１２、及び係止突出部１３が、高強度繊維補強モルタル及び高強度繊維補強モルタルに混入された湾曲鋼補強繊維により一体的に構成した。【選択図】図２
