Fabricated welding-free steel-concrete combined bridge deck structure
The invention discloses a fabricated welding-free steel-concrete combined bridge deck structure, which belongs to the technical field of bridge engineering, and comprises a steel top plate and a pavement layer above the steel top plate, and a corrugated steel support structure is arranged below the steel top plate; the pavement layer is formed by pouring ultra-high performance concrete, and the tail end of a connecting screw rod for connecting the steel top plate and the corrugated steel supporting structure extends into the pavement layer. The structure has the advantages of being large in structural rigidity, good in fatigue performance, high in construction efficiency, reliable in construction quality and replaceable in failure component, a traditional single U rib is replaced with the continuous corrugated steel plate, and the overall structural rigidity is improved; the adverse effect of weld defects on the structural fatigue performance is eliminated by adopting a bolting mode; the overall rigidity of the structure can be improved through the ultra-high performance concrete, and fatigue cracking of the steel bridge deck can be restrained; all the components can be prefabricated in advance and then assembled on site, the construction speed is higher, and the quality is easy to guarantee; fatigue failure components can also be directly dismounted and replaced, and the use safety of the bridge deck slab is guaranteed.
本发明公开了一种装配式免焊钢混组合桥面板结构，属于桥梁工程技术领域，包括钢顶板及其上方的铺装层，钢顶板下方设有波纹钢支撑结构；铺装层由超高性能混凝土浇筑而成，连接钢顶板与波纹钢支撑结构的连接螺杆末端延伸至铺装层内。本发明具有结构刚度大、疲劳性能好、施工效率高、施工质量可靠、失效构件可更换的优点，采用连续波形钢板取代传统单个U肋，提高结构整体刚度；采用栓接方式消除了焊缝缺陷对结构疲劳性能的不利影响；超高性能混凝土不仅可以提升结构的整体刚度，还可抑制钢桥面板的疲劳开裂；各个构件均可提前预制后现场拼装，施工速度更加高效，且质量易保证；疲劳失效构件也可直接进行拆除更换，保证桥面板的使用安全。
