SUPPORT STRUCTURE FOR TEMPORARY PIER AND RENEWAL METHOD OF BRIDGE UPPER STRUCTURE
To provide a support structure for a temporary pier which satisfies earthquake-resistant performance against a level 2 earthquake motion and can be installed at a low cost with a small amount of steel used without increasing the size, and to provide a method for renewing a bridge upper structure using the support structure.SOLUTION: In a support structure of a temporary pier 1 constructed between two existing piers P2, P3 erected separately and obtained by combining a plurality of steel materials, a plurality of cross beams 4 and a plurality of girder materials 5 installed on the plurality of cross beams 4 are provided, and the cross beams 4 are bridged and joined between a pair of frame bodies 3 respectively surrounding peripheries of the two existing piers P2, P3.SELECTED DRAWING: Figure 1
【課題】レベル２地震動に対する耐震性能を満たし、大型化せずに鋼材使用量が少なく安価に設置可能な仮設橋脚の支持構造及びそれを用いた橋梁上部構造の更新方法を提供する。【解決手段】離間して立設された２つの既設橋脚Ｐ２，Ｐ３の間に構築される複数の鋼材が組み合わされた仮設橋脚１の支持構造において、複数の横梁４と、これらの複数の横梁４上に設置された複数の桁材５と、を備え、前記横梁４を、前記２つの既設橋脚Ｐ２，Ｐ３の周囲をそれぞれ取り囲む一対の枠体３間に架け渡して接合する。【選択図】図１
