Cast-in-place concrete cantilever flange plate steel-concrete composite beam bridge deck and construction method
The invention relates to a cast-in-place concrete cantilever flange plate steel-concrete composite beam bridge deck and a construction method. The construction method comprises the following steps that an adjustable movable formwork is installed; mounting a bracket and a cantilever template; installing a side mold; adjusting the template; the cantilever end bridge deck and the framing section bridge deck on the same side are integrally poured; and constructing a middle-section bridge deck slab. The method has the beneficial effects that the steel mold serves as a part of a framing steel box main beam structure and also serves as a continuous disassembly-free bottom formwork for pouring a bridge floor, and bridge floor pouring construction is facilitated; the cantilever end bridge deck and the framing section bridge deck on the same side are integrally formed in a pouring mode, the quality problem caused by independent pouring of the cantilever end in a traditional technology is avoided, and the overall performance of the bridge deck is improved. The middle-section bridge deck slab is a reserved pouring section, finally pouring construction is conducted, the effect similar to a post-pouring belt can be formed, the middle-section bridge deck slab can be properly poured through micro-expansion concrete, the overall performance of the bridge deck slab structure is improved, the adjustable movable formwork is arranged on the reserved pouring section, the structure is reasonable, and space is saved.
本发明涉及一种现浇混凝土悬臂翼缘板钢混组合梁桥面及施工方法,包括以下步骤:安装可调移动模架;安装托架与悬臂模板;安装侧模;调节模板;同侧悬臂端桥面板与分幅段桥面板整体浇筑;施工中间段桥面板。本发明的有益效果是:钢模既作为分幅钢箱主梁结构的一部分,又作为浇筑桥面的连续免拆底模板,方便了桥面浇筑施工;同侧的悬臂端桥面板与分幅段桥面板为整体浇筑成型,避免了传统工艺中悬臂端单独浇筑引起的质量问题,提高了桥面板的整体性能;中间段桥面板为预留浇筑段,最后浇筑施工,可形成类似后浇带的作用,中间段桥面板可适当采用微膨胀混凝土浇筑,以利于桥面板结构整体性能,可调移动模架设于预留浇筑段,结构合理,节约了空间。
