Fabricated prestressed corrugated web steel box-concrete combined simply supported beam
The invention relates to the field of bridges, in particular to a fabricated prestressed corrugated web steel box-concrete combined simply supported beam. The simply supported beam is prepared by the following steps: prefabricating and machining single corrugated web steel box-concrete composite beams with prestress, wherein the prefabricated corrugated web steel box-concrete composite beams are connected through K-shaped supporting steel cross beams, and prefabricated reinforced concrete top plates are connected through cast-in-place reinforced concrete plates; casting reinforced concrete side wing plates in place on the outer sides of the corrugated web steel box-concrete combined beams, and arranging beam end cantilever steel beams below the beam end cast-in-place reinforced concrete side wing plates so as to form the fabricated prestressed corrugated web steel box-concrete combined simply supported beam. According to the fabricated prestressed corrugated web steel box-concrete combined simply supported beam, the stress characteristic of the corrugated steel web is fully utilized, and the combined simply supported beam is light in self weight, easy to machine and manufacture, high in bridge construction speed, convenient to apply in a large scale and wide in practicability.
本发明涉及桥梁领域，具体涉及到一种装配式预应力波形腹板钢箱‑混凝土组合简支梁；包括：预制加工设置有预应力的单片波形腹板钢箱‑混凝土组合梁，预制波形腹板钢箱‑混凝土组合梁之间由K型支撑钢横梁连接，预制钢筋混凝土顶板由现浇钢筋混凝土板连接，在波形腹板钢箱‑混凝土组合梁外侧现浇钢筋混凝土边翼板，并在梁端现浇钢筋混凝土边翼板下面设置梁端悬臂钢梁，形成装配式预应力波形腹板钢箱‑混凝土组合简支梁。本发明装配式预应力波形腹板钢箱‑混凝土组合简支梁，充分利用了波形钢腹板的受力特性，自重轻，易于加工制造，施工质量容易保证，桥梁施工速度快，便于大量应用，具有较广泛的实用性。
