Spine girder bridge rear-mounted cantilever rib plate mixed connection structure with inclined struts
The invention provides a backbone beam bridge rear-mounted cantilever rib plate mixed type connecting structure with inclined struts. 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; 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; cantilever prefabricated inclined struts are arranged at the lower edges ofthe roots of the cantilever rib plates; the cantilever arm prefabricated inclined struts are in direct contact with the arc-shaped surface of the bottom edge of the outer side of the core longitudinal beam web to form hinge joint; the upper half part of the cantilever rib plate is provided with a vertical rear-mounted cantilever rib plate wet joint which is in wet joint with the core longitudinalbeam; and the cantilever prefabricated inclined strut and the rear-mounted cantilever rib plate wet joint are combined to form mixed connection. According to the structure, reliable connection between the rear-mounted cantilever arm section and the core longitudinal beam of the composite-section backbone beam can be ensured, construction is convenient, the design and construction key technology of a section prefabricated assembled concrete bridge can be improved, and development of the section beam prefabricated assembling technology is promoted.
本发明提供一种带斜撑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挑臂预制斜撑；所述挑臂预制斜撑与核心纵梁腹板外侧底缘的弧形面直接接触形成铰接；所述挑臂肋板，在上半部分设置有一道竖向的后装挑臂肋板湿接缝与核心纵梁湿接；所述挑臂预制斜撑与后装挑臂肋板湿接缝组合形成混合式连接。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，可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。
