CONSTRUCTION METHOD OF CABLE-STAYED BRIDGE
PROBLEM TO BE SOLVED: To provide a construction method of a cable-stayed bridge capable of installing a main digit between side span preceding the center span without building a plurality of intermediate piers at the side span even when the span length of the side span is large.SOLUTION: As illustrated in Figs. 3(A) and (B), an intermediate pier 7 is built, and a temporary support 21 is provided to the intermediate pier 7 between a main pier 5 and an end pier 6. Subsequently, a temporal diagonal member 22 is installed by extending from the intermediate pier 7 in both bridge axial directions between a PC digit 4A and the temporary support 21 by a cantilever extension method as illustrated in Figs. 3(C) and (D). Subsequently, a PC digit 4A is bridged across a side span SS while supporting the PC digit 4A with the temporal diagonal member 22 as illustrated in Figs. 3(E) and (F).SELECTED DRAWING: Figure 3
【課題】側径間の支間長が長くても、側径間に複数の中間橋脚を設けることなく、中央径間に先行して側径間に主桁を架設できる斜張橋の架設方法を提供する。【解決手段】図３（Ａ）（Ｂ）に示されるように、主橋脚５と端橋脚６との間に中間橋脚７を設けると共に中間橋脚７に仮支柱２１を設け、図３（Ｃ）、（Ｄ）に示されるように、中間橋脚７から橋軸方向の両方に片持ち張り出し工法により延伸したＰＣ桁４Ａと仮支柱２１との間に仮斜材２２を張り、図３（Ｅ）、（Ｆ）に示されるように、仮斜材２２にＰＣ桁４Ａを支持させながらＰＣ桁４Ａを側径間ＳＳに架け渡す。【選択図】図３
