MAIN GIRDER CONTINUOUS RIGID CONNECTION METHOD
To provide a construction method capable of achieving both frictional connections between each girder end of a left span main girder and a right span main girder and a connection plate and reduction of the negative moment based on the dead load of each main girder, and rigidly connecting each main girder and a bridge pier.SOLUTION: In a main girder continuous rigid connection method, a connecting plate is temporarily fastened to simply support a left span main girder and a right span main girder before placing a bridge body concrete, and a connecting plate is permanently fastened to connect the left span main girder and the right span main girder after appropriately absorbing the slight upward displacement of the girder ends of the respective main girders by placing bridge body concrete, and since each main girder and the bridge pier are connected by the connecting strip member, both main girders can be rigidly connected to the bridge pier while preventing the generation of a negative bending moment, and the connected main girders can be rigidly connected to the bridge pier.SELECTED DRAWING: Figure 5
【課題】 左径間主桁及び右径間主桁の各桁端と連結板との摩擦接合と、各主桁の死荷重に基づく負のモーメントの減殺とを両立することができると共に、各主桁と橋脚とを剛結合することができる工法の提供。【解決手段】 本発明に係る主桁連続化剛結合工法は、橋体コンクリート打設前は、連結板を仮止めして左径間主桁及び右径間主桁を単純支持する一方、橋体コンクリート打設によって各主桁の桁端が僅かに上方に変位するのを適切に吸収した後に、連結板を本止めして左径間主桁及び右径間主桁を連結し、連結条材によって各主桁と橋脚とを連結するので、負の曲げモーメントの発生を防止しつつ強固に両主桁を連続化することができると共に、さらには該連続化した両主桁を橋脚と剛結合することができる。【選択図】 図５
