Spine girder bridge rear-mounted cantilever rib plate wet joint structure free of formwork dismounting
The invention provides a spine girder bridge after-loading cantilever rib plate wet joint structure free of formwork removal, which is suitable for a composite-section spine girder bridge with prefabricated sections, and an after-loading cantilever is a prefabricated concrete member assembled by the sections and follows the construction time sequence that a core longitudinal beam is erected step by step after being constructed; according to the post-assembled prefabricated cantilever member, an integrated prefabricated formwork is arranged at the wet joint position of the root of a rib plate;and in the prefabricated template, a wet joint of the rear-mounted cantilever rib plate is arranged between the rear-mounted cantilever rib plate and the core longitudinal beam. According to the structure, reliable connection and convenient construction of the rear-mounted cantilever arm section and the core longitudinal beam of the composite cross-section spine beam can be ensured, the technicalbottleneck of transportation and construction of large-size section beams is broken through, the design and construction key technology of section prefabricated assembled concrete bridges is improved,and development of the section beam prefabricated assembling technology is promoted.
本发明提供了一种免拆模板的脊骨梁桥后装挑臂肋板湿接缝构造，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；所述后装的预制挑臂构件，在肋板根部湿接缝位置布置有一体化的预制模板；所述预制模板内、后装挑臂肋板与核心纵梁间设置后装挑臂肋板湿接缝。本发明可确保复合截面脊骨梁的后装挑臂节段与核心纵梁连接可靠、施工便捷，突破大尺寸节段梁运输、施工的技术瓶颈，提升节段预制拼装混凝土桥梁的设计和施工关键技术，推动节段梁预制拼装技术的发展。
