Backbone beam bridge rear-mounted cantilever rib plate mixed connection structure with bearing function
The invention provides a backbone beam bridge rear-mounted cantilever rib plate mixed type connecting structure with a bearing function. The backbone beam bridge rear-mounted cantilever rib plate mixed type connecting structure is suitable for a composite-section backbone beam bridge with prefabricated sections. A rear-mounted cantilever arm is a prefabricated concrete member assembled by sections, and follows the construction time sequence that the core longitudinal beam is erected step by step after being constructed; prefabricated supports are arranged on the lower edges of the roots of thecantilever rib plates and connected with the supports of the core longitudinal beams in a matched and dry mode; the cantilever rib plate is provided with a vertical post-mounted cantilever rib platewet joint above the prefabricated support, and the vertical post-mounted cantilever rib plate wet joint is in wet joint with the core longitudinal beam; the prefabricated support and the rear-mountedcantilever rib plate wet joint are combined to form novel mixed connection. The reasonable rib plate transverse mixing type connecting structure can ensure reliable connection and convenient construction, reduces the risk of aloft work, and is suitable for various bridges with complex sections and ultrahigh gradual change and curve sections.
本发明提供了一种带承托的脊骨梁桥后装挑臂肋板混合式连接构造，适用于节段预制的复合截面脊骨梁桥；所述后装挑臂为节段拼装的预制混凝土构件，遵循核心纵梁完工后再逐步架设的施工时序；所述挑臂肋板在根部下缘设置有预制承托，与核心纵梁的承托匹配干接；所述挑臂肋板在预制承托以上设置有竖向的后装挑臂肋板湿接缝与核心纵梁湿接；所述预制承托与后装挑臂肋板湿接缝组合形成一种新型的混合式连接。本发明合理的肋板横向混合式连接构造，可确保连接可靠、施工便捷，减小高空作业风险，适用于各类复杂断面、超高渐变及曲线段桥梁。
