BRIDGE FALL PREVENTION STRUCTURE OF SKEW BRIDGE
PROBLEM TO BE SOLVED: To provide a bridge fall prevention structure of a skew bridge capable of preventing a bridge fall by rationally reinforcing a support part.SOLUTION: A bridge part 3 is respectively supported in obtuse angle parts 31 and 32 and an acute angle part by support parts 4, 4, etc., and the support parts 4, 4, etc. comprise a lower shoe 46 fixed to a bridge abutment 2 and an upper shoe 47 placed in an upper part of the lower shoe 46, relatively displaceable in the horizontal direction with the lower shoe 46 and fixing the bridge part 3, and comprise reinforcement parts 5 and 5 for reinforcing only the support parts 4 and 4 for supporting the obtuse angle parts 31 and 32, and the reinforcement parts 5 and 5 comprise a fixing part 54 fixed to the bridge abutment 2 adjacently to the support parts 4 and 4 for supporting the obtuse angle parts 31 and 32 and an abutting part 55 joined to an upper part of the fixing part 54 and capable of abutting on the upper shoe 47 of the support parts 4 and 4 for supporting the obtuse angle parts 31 and 32, and when external force for pressing the abutting part 55 from the upper shoe 47 becomes a predetermined value or more, a joining part 56 between the fixing part 54 and the abutting part 55 ruptures.SELECTED DRAWING: Figure 3
【課題】合理的に支承部を補強し、落橋を防止することができる斜橋の落橋防止構造を提供する。【解決手段】橋梁部３は、鈍角部３１，３２および鋭角部がそれぞれ支承部４，４…に支持されていて、支承部４，４…は、橋台２に固定される下沓４６と、下沓４６の上部に載置され下沓４６と水平方向に相対変位可能で橋梁部３が固定される上沓４７と、を有していて、鈍角部３１，３２を支持する支承部４，４のみを補強する補強部５，５を有し、補強部５，５は、鈍角部３１，３２を支持する支承部４，４と隣接して橋台２に固定される固定部５４と、固定部５４の上部に接合され鈍角部３１，３２を支持する支承部４，４の上沓４７が当接可能な当接部５５と、を有し、当接部５５が上沓４７から押圧される外力が所定の値以上となると、固定部５４と当接部５５との接合部５６が破断する。【選択図】図３
