Spine beam bridge rear-mounted cantilever top plate wet joint structure free of formwork dismounting
The invention provides a spine girder bridge rear-mounted cantilever top plate wet joint structure free of formwork dismounting. The spine girder bridge rear-mounted cantilever top plate wet joint structure is suitable for a composite-section spine girder bridge with prefabricated sections. The 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; a rear-mounted cantilever top plate wet joint is arranged between the rear-mounted cantilevertop plate and the core longitudinal beam; and a prefabricated bottom die is arranged at the wet joint of the root of the top plate of the prefabricated after-loading cantilever member. According to the spine girder bridge rear-mounted cantilever top plate wet joint structure, reliable connection between the rear-mounted cantilever arm section and the core longitudinal beam of the composite-sectionbackbone beam can be ensured, the construction is convenient, the design and construction key technology of the section prefabricated assembled concrete bridge is improved, and development of the section beam prefabricated assembling technology is promoted.
本发明提供一种免拆模板的脊骨梁桥后装挑臂顶板湿接缝构造，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；所述后装挑臂顶板与核心纵梁间，设置有后装挑臂顶板湿接缝；所述预制的后装挑臂构件在顶板根部湿接缝位置布置有预制底模。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，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。
