METHOD FOR REBUILDING BRIDGE
To provide an erection structure and erection method for composite panel bridges which excel in workability, enable rapid construction on site, and are structurally stable compared to conventional composite panel bridges.SOLUTION: A panel unit 1 comprises: a main girder 2 in the bridge axis direction; a bottom steel plate 3 fixed to an upper surface of the main girder 2; and a plurality of I-shaped steels 4 arranged at intervals in the bridge axis direction on an upper surface of the bottom steel plate 3. Floor slab concrete 5 is integrated on the upper surface of the bottom steel plate 3. A plurality of panel units 1 are installed between a leg base and a bridge pier or between bridge piers, and are arranged in parallel in the direction perpendicular to the bridge axis and connected. A part of an upper flange side protrudes as a protruding part 2a at an end of the main girder 2 of the panel unit 1. The protruding part 2a is placed on an upper surface of a horizontal girder 15. The protruding parts 2a of the main girder 2 of the panel unit 1 that are continuous in the bridge axis direction across the horizontal girder 15 are connected to each other by bolting via splice plates 21, 22.SELECTED DRAWING: Figure 11
【課題】従来の合成パネル橋梁に比べて、施工性に優れ、現場でのさらなる急速施工が可能となり、構造的にも安定した合成パネル橋梁の架設構造および架設方法を提供する。【解決手段】パネルユニット１は、橋軸方向の主桁２と、主桁２の上面に固定された底鋼板３と、底鋼板３の上面に橋軸方向に間隔をおいて配置された複数のＩ形鋼４とを構成要素とし、底鋼板３の上面に床版コンクリート５が一体化されている。パネルユニット１を脚台と橋脚または橋脚間に架設し、橋軸直角方向に複数並列配置して連結する。パネルユニット１の主桁２の端部は上フランジ側の一部が突出部２ａとして突出しており、この突出部２ａを横桁１５の上面に載置する。横桁１５を挟んで橋軸方向に連続するパネルユニット１の主桁２の突出部２ａどうしをスプライスプレート２１、２２を介してボルト接合により連結する。【選択図】図１１
