Steel-UHPFRC high-performance combined bridge deck slab structure and construction method thereof
The invention discloses a steel-UHPFRC high-performance combined bridge deck structure which comprises a pavement layer, a UHPFRC structural layer, a high-toughness epoxy resin adhesive layer and a steel bridge deck. The UHPFRC structure layer and the steel top plate are bonded through a high-toughness epoxy resin adhesive layer; two-sided fillet welds are arranged at the joints of the U-shaped longitudinal ribs and the top plate, and novel holes are formed in the crossed parts of the longitudinal ribs and the transverse partition plates. The construction method comprises the steps that the prefabricated UHPFRC structure layer is manufactured in a blocking mode, the steel bridge deck is manufactured, the prefabricated UHPFRC structure layer and the steel bridge deck are bonded, and bridge deck pavement is conducted. The method has the advantages of being reliable in connection, easy and convenient to construct, convenient to maintain in the later period and the like, the anti-fatigue strength of a combined bridge deck structural system can be remarkably improved, and fatigue cracking of the steel bridge deck and damage to bridge deck pavement are prevented.
本发明公开了一种钢‑UHPFRC高性能组合桥面板结构，包括铺装层、UHPFRC结构层、高韧性环氧树脂胶粘层、钢桥面板；所述UHPFRC结构层和钢顶板由高韧性环氧树脂胶粘层粘结；本发明在U形纵肋与顶板的连接处设置双面角焊缝，并在纵肋与横隔板交叉部位设置新型开孔。本发明施工方法的步骤包括：预制超高性能纤维增强混凝土结构层分块制作、钢桥面板制作、粘结所述预制UHPFRC结构层和所述钢桥面板、进行桥面铺装。本发明具有连接可靠、施工简便、后期维修保养便捷等优点，能显著提高组合桥面板结构体系的抗疲劳强度，防止钢桥面板疲劳开裂和桥面铺装损坏。
