Large-span suspension bridge GFRP rib prefabricated slab composite beam bridge deck system and construction method thereof
The invention discloses a large-span suspension bridge GFRP rib prefabricated slab composite beam bridge deck system, which comprises steel longitudinal beams, transverse tie beams, prefabricated bridge deck slabs and cast-in-place concrete joints, wherein the plurality of steel longitudinal beams are arranged in parallel at intervals, the two ends of the steel longitudinal beams are fixedly connected through the transverse tie beams, stud shear keys are arranged at the top ends of the steel longitudinal beams, the prefabricated bridge deck slab is erected above the two adjacent steel longitudinal beams, every two adjacent prefabricated bridge deck slabs are connected through the cast-in-place concrete joint, GFRP ribs are arranged in the prefabricated bridge deck slabs, the ends of the GFRP ribs protrude out of the prefabricated bridge deck slabs, and the reserved GFRP ribs at the ends of the prefabricated bridge deck slabs are embedded between the stud shear keys and connected with the GFRP ribs in the cast-in-place concrete joint in a binding and lap joint mode. According to the large-span suspension bridge GFRP rib prefabricated slab composite beam bridge deck system and the construction method thereof, cracks of the concrete slabs can be effectively reduced, and the durability problem of the bridge deck system due to the fact that cracked steel bars are exposed in a chlorine salt environment can be solved.
本发明公开了一种大跨悬索桥GFRP筋预制板组合梁桥面系，包括钢纵梁、横系梁、预制桥面板以及现浇混凝土接缝，多条钢纵梁平行间隔设置，多条钢纵梁的两端均通过横系梁固定连接，钢纵梁的顶端布置有栓钉剪力键，预制桥面板架设于相邻两钢纵梁上方，相邻两预制桥面板之间通过现浇混凝土接缝连接，预制桥面板内部设置有GFRP筋且GFRP筋的端部凸伸于预制桥面板外，预制桥面板板端预留GFRP筋嵌于栓钉剪力键之间且与现浇混凝土接缝中的GFRP筋绑扎搭接。本大跨悬索桥GFRP筋预制板组合梁桥面系及其施工方法，既能有效减少混凝土板裂缝产生，又能解决开裂后钢筋暴露在氯盐环境中的桥面系耐久性问题。
