Prefabricated assembly type steel-UHPC light combined bridge deck slab structure and construction method
The invention relates to a prefabricated assembly type steel-UHPC light combined bridge deck slab structure and a construction method, and the prefabricated assembly type steel-UHPC light combined bridge deck slab structure comprises longitudinal steel main beams, a steel bridge deck slab, longitudinal stiffening ribs, transverse distribution steel bars, shearing force reinforcing keys, longitudinal steel connecting pieces, transverse steel connecting pieces and a bridge deck slab thin-layer concrete layer, a bridge deck slab thin-layer concrete layer is laid on the steel bridge deck slab, and the steel bridge deck slab and the bridge deck slab thin-layer concrete layer are connected in an anchoring mode through longitudinal stiffening ribs and transversely-distributed steel bars. The structure is simple, the mechanical property is good, reliable connection between the UHPC and the steel plate is guaranteed, the field operation amount is greatly reduced, construction is convenient and fast, meanwhile, the stiffening ribs can improve the flexural rigidity of the bridge deck slab, and the shearing force reinforcing keys can improve the anti-sliding capacity between the rigid slab and the UHPC slab and enhance the crack resistance and fatigue resistance.
本发明涉及一种预制装配式钢‑UHPC轻型组合桥面板结构及施工方法，包括纵向钢主梁、钢桥面板、纵向加劲肋、横向分布钢筋、剪力增强键、纵向钢连接件、横向钢连接件及桥面板薄层混凝土层，所述纵向钢主梁间隔布置焊接于所述钢桥面板下方，所述钢桥面板上方铺设桥面板薄层混凝土层，所述钢桥面板与桥面板薄层混凝土层之间通过纵向加劲肋和横向分布钢筋锚固连接。本发明结构简单且力学性能好，即保证了UHPC和钢板间的可靠连接，又大幅减少了现场作业量，施工便捷，同时加劲肋可提高桥面板抗弯刚度，剪力增强键可提高刚面板和UHPC面板间的抗滑移能力，增强抗裂和抗疲劳性能。
