Fabricated UHPC bridge deck slab structure and construction method thereof
The fabricated UHPC bridge deck slab structure comprises a plurality of prefabricated UHPC bridge deck slabs and steel beam diaphragm plates, cast-in-place UHPC joints are arranged between the adjacent prefabricated UHPC bridge deck slabs, longitudinal ribs are arranged at the bottoms of the UHPC bridge deck slabs, steel transverse ribs which correspond to the steel beam diaphragm plates and are fixedly connected with the steel beam diaphragm plates are fixedly connected below the longitudinal ribs, and the steel transverse ribs are fixedly connected with the steel beam diaphragm plates. End reinforcing steel bottom plates which are fixedly connected with each other are arranged below the longitudinal ribs at the ends of the adjacent prefabricated UHPC bridge deck slabs, shearing force connecting pieces are fixedly connected to the joints of the end reinforcing steel bottom plates, and roundabout steel bars and longitudinal straight bars which extend to the joints are embedded in the ends of the adjacent UHPC bridge deck slabs. The fabricated UHPC bridge deck slab structure has the advantages that construction is convenient, the tensile strength of the joints is high, and the bridge deck slab is not prone to cracking.
本发明公开了一种装配式UHPC桥面板结构及其施工方法，包括多块预制UHPC桥面板与钢梁横隔板，相邻预制UHPC桥面板之间设置有现浇UHPC接缝，UHPC桥面板底部设置有纵肋，纵肋下方固接有与钢梁横隔板对应并固接的钢横肋，相邻预制UHPC桥面板端部的纵肋下方设置有互相固接的端部加强钢底板，端部加强钢底板于接缝处固接有剪力连接件，相邻UHPC桥面板端部埋设有延伸至接缝的迂回钢筋与纵向直筋。本发明提出的装配式UHPC桥面板结构，具有施工便利、接缝处抗拉强度高、桥面板不易开裂的优点。
