Fabricated steel-concrete composite beam formwork-free construction bridge deck slab
The invention relates to the field of bridges, in particular to a fabricated steel-concrete composite beam formwork-free construction bridge deck slab. Comprising prefabricated steel-concrete composite beams, closed profiled steel sheets arranged at the tops of the prefabricated steel-concrete composite beams, prefabricated reinforced concrete bridge decks poured on the prefabricated steel-concrete composite beams, open profiled steel sheets arranged between the prefabricated steel-concrete composite beams and inter-beam reinforced concrete bridge decks poured on the open profiled steel sheets. A cantilever steel beam is arranged on the outer side of the prefabricated steel-concrete composite beam, a steel joist is arranged at the end of the cantilever steel beam in the longitudinal bridge direction, an open profiled steel sheet is arranged on the steel joist, a cantilever reinforced concrete bridge deck is poured on the open profiled steel sheet, and the steel-concrete composite beam bridge is formed. In the prefabricating and cast-in-place construction processes of the composite beam, formworks are not needed, construction is very convenient and rapid, a large amount of manpower and material resources can be saved, meanwhile, the stress characteristics of the bridge are fully considered, the structure is more reasonable, and wide practicability is achieved.
本发明涉及桥梁领域，具体涉及一种装配式钢混组合梁无模板施工桥面板；包括预制钢混组合梁，在预制钢混组合梁顶部设置闭口压型钢板，浇筑于预制钢混组合梁上的预制钢筋混凝土桥面板，设置于预制钢混组合梁之间的开口压型钢板以及浇筑在开口压型钢板上的梁间钢筋混凝土桥面板；预制钢混组合梁外侧设置悬臂钢梁，在悬臂钢梁端部沿纵桥向设置钢托梁，钢托梁上设置开口压型钢板，并在开口压型钢板上浇筑悬臂钢筋混凝土桥面板，形成钢混组合梁桥。本发明在组合梁预制及现浇施工过程中，均不需要模板，施工非常方便快捷，可节省大量人力物力，同时充分考虑了桥梁受力特点，结构更加合理，具有广泛的实用性。
