Novel connecting structure for new and old bridge joint of bridge with flange plate and construction method
The invention discloses a new and old bridge joint novel connecting structure of a bridge with a flange plate and a construction method. The new and old bridge joint novel connecting structure comprises a plurality of corrugated steel plates and a plurality of prefabricated bridge deck slabs, each corrugated steel plate comprises a corrugated section and fixing plates at the two ends of the corrugated section, and the corrugated sections are vertically arranged; the fixing plates at the two ends of the corrugated section are fixed to a flange plate of a new bridge and a flange plate of an old bridge respectively, the multiple corrugated steel plates are distributed along a joint between the new bridge and the old bridge, and the prefabricated bridge deck is placed above the corrugated steel plates and clamped between the new bridge deck and the old bridge deck. The corrugated steel plate has flexibility in the horizontal transverse direction, and certain transverse deformation stretching and retracting can be achieved. When the new bridge shrinks and creeps, the transverse deformation difference of the new bridge and the old bridge caused by the shrinkage and creeps can be dissipated through the transverse flexibility of the corrugated steel plate, so that the additional internal force in the direction can be greatly reduced, and the influence caused by the transverse deformation difference (caused by the shrinkage and creeps) of the new bridge and the old bridge is effectively relieved.
本发明公开一种带翼缘板桥梁的新旧桥接缝新型连接结构及施工方法，包括多个波形钢板和多个预制桥面板，所述波形钢板包括波形段和波形段两端的固定板，波形段呈竖向设置，波形段两端的固定板分别固定至新桥的翼缘板和旧桥的翼缘板上，多个波形钢板沿新桥和旧桥之间的接缝分布，预制桥面板放置于波形钢板上方，且夹持于新桥面板和旧桥面板之间。波形钢板在水平横向具有柔性，可实现一定的横向变形伸缩。当新桥发生收缩徐变时，其导致的新旧桥横向变形差可通过波形钢板的横向伸缩性进行耗散，由此可大幅减少该方向上的附加内力，从而有效缓解新旧桥横向变形差(收缩徐变所致)带来的影响。
