Rapidly-constructed steel-concrete composite beam concrete bridge deck slab and hoisting system thereof
The invention discloses a rapidly-constructed steel-concrete composite beam concrete bridge deck slab which comprises a middle plate and cantilever slabs arranged on the two sides in the transverse direction of a bridge, and the middle plate and the cantilever slabs are connected through corresponding connecting cross beams to form a prefabricated integral structure. The longitudinal length of theconnecting cross beam is 30%-35% of the longitudinal length of the middle plate and the longitudinal length of the cantilever plate. And shear grooves are formed between the two longitudinal sides ofthe connecting cross beams and the corresponding middle plates and between the two longitudinal sides of the connecting cross beams and the corresponding cantilever plates correspondingly, and reliable connection between the concrete bridge deck slab and the top of the steel beam is achieved through a plurality of shear connecting pieces arranged in the shear grooves. The invention further discloses a rapidly-constructed steel-concrete composite beam concrete bridge deck slab hoisting system. The requirement for arranging a large number of shear connectors is met, and the problems that due totransverse partitioning, the integrity of the bridge deck slab is poor, and the installation workload of a cast-in-place construction formwork is large are solved.
本发明公开了一种快速施工的钢‑混组合梁混凝土桥面板，所述混凝土桥面板包括中间板和横桥向两侧设置的悬臂板，且所述中间板和所述悬臂板之间通过对应的联系横梁连接，为预制整体结构；所述联系横梁的纵向长度为所述中间板和所述悬臂板的纵向长度的30％‑35％，且所述联系横梁的纵向两侧分别与对应的所述中间板和所述悬臂板之间形成剪力槽，通过所述剪力槽中设置的若干剪力连接件，实现所述混凝土桥面板与所述钢梁顶部的可靠连接。本发明还公开了一种快速施工的钢‑混组合梁混凝土桥面板吊装系统。本发明既满足布置大量剪力连接件的需要，且避免了横向分块带来导致桥面板整体性差、现浇施工模板安装工作量大的问题。
