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
