Segmented pouring joint structure of steel-ultra-high performance concrete combined bridge deck slab and construction method of segmented pouring joint structure
The invention relates to a steel-ultra-high performance concrete combined bridge deck slab segmented pouring joint structure and a construction method thereof, and the steel-ultra-high performance concrete combined bridge deck slab segmented pouring joint structure comprises a steel bridge deck slab, an ultra-high performance concrete layer, a reinforcing mesh and a bridge deck pavement layer, the ultra-high-performance concrete layer comprises a first-pouring ultra-high-performance concrete layer and a second-pouring ultra-high-performance concrete layer, a joint is formed between the first-pouring ultra-high-performance concrete layer and the second-pouring ultra-high-performance concrete layer, and a reinforcing mesh and a steel fiber grid are sequentially laid at the joint and wrapped by the ultra-high-performance concrete layer. And a bridge deck pavement layer is paved above the ultra-high performance concrete layer. The fiber grids are laid at the joint interface of the ultrahigh concrete, the tensile strength and the crack resistance of the joint part are improved, and the sectional pouring joint structure of the steel-ultrahigh performance concrete combined bridge deck slab is convenient to take materials, simple in structure and convenient to construct and has good technical and economic benefits.
本发明涉及一种钢‑超高性能混凝土组合桥面板分段浇筑接缝构造及其施工方法，包括钢桥面板、超高性能混凝土层、钢筋网及桥面铺装层，钢桥面板的上方铺设超高性能混凝土层，超高性能混凝土层包括先浇筑超高性能混凝土层及后浇筑超高性能混凝土层，先浇筑超高性能混凝土层及后浇筑超高性能混凝土层之间形成接缝，接缝处依次铺设钢筋网及钢纤维网格，钢筋网及钢纤维网格被超高性能混凝土层包裹，超高性能混凝土层上方铺设桥面铺装层。本发明在超高混凝土接缝界面处铺设纤维网格，提高了接缝部位的抗拉强度和抗裂能力，该钢－超高性能混凝土组合桥面板分段浇筑接缝构造取材方便、构造简单、施工便捷，具有良好的技术经济效益。
