Large cantilever steel plate-concrete composite structure and construction method thereof
The invention relates to a large cantilever steel plate-concrete composite structure and a construction method thereof, the large cantilever steel plate-concrete composite structure is used for controlling downwarping of a large cantilever of a bridge, and the large cantilever steel plate-concrete composite structure comprises a steel plate structure and a filled concrete structure; the steel plate structure comprises a bottom steel plate connected with a main beam of the bridge; the stiffening ribs are transversely arranged on the bottom steel plate side by side, and a concrete pouring space is formed between every two adjacent stiffening ribs; the through holes are formed in the stiffening rib web, and pouring concrete penetrates through the through holes to form a concrete tenon structure. Compared with the prior art, the method has the advantages that the rigidity of the bottom steel plate is improved and downwarping of the cantilever section is effectively controlled by arranging the mode that the transverse profile steel stiffening ribs are connected with the bottom steel plate.
本发明涉及一种大悬臂钢板‑混凝土组合结构及其施工方法，用于控制桥梁的大悬臂下挠，该大悬臂钢板‑混凝土组合结构包括钢板结构和填充的混凝土结构；所述钢板结构包括：与所述桥梁的主梁相连的底钢板；横向并排设置在所述底钢板上的若干加劲肋，相邻两个加劲肋之间形成混凝土的浇筑空间；设置在所述加劲肋腹板的若干通孔，浇筑混凝土穿过所述通孔形成混凝土榫结构。与现有技术相比，本发明具有通过设置横向型钢加劲肋与底钢板相连接的方式，以提高底钢板刚度，有效控制悬臂段下挠等优点。
