Profile steel-UHPC combined bridge deck prefabricated slab and machining method and application thereof
The invention discloses a section steel-UHPC (Ultra High Performance Concrete) combined bridge deck precast slab as well as a processing method and application thereof. The bridge floor prefabricated slab comprises a plurality of section steel arranged in the longitudinal bridge direction and distributed at intervals in the transverse bridge direction, UHPC panels fixedly connected to the section steel and UHPC end formwork plates arranged on the two longitudinal end faces of the prefabricated bridge panel, and the UHPC end formwork plates are fixedly connected to the intervals between the adjacent section steel ends in the transverse bridge direction. The processing method and the application are carried out by using the profile steel-UHPC bridge floor prefabricated slab. The UHPC end formwork plates are arranged at the intervals of the ends of all the structural steel, the transverse connection of the structural steel-UHPC combined bridge deck prefabricated slab at the longitudinal ends is enhanced, and therefore the transverse bending resistance and crack resistance of the structural steel-UHPC combined bridge deck prefabricated slab during hoisting are improved.
本发明公开了一种型钢‑UHPC组合桥面预制板及加工方法和应用。桥面预制板包括多根纵桥向设置且沿横桥向间隔分布的型钢、固定连接在型钢上的UHPC面板和设置在预制桥面板两纵向端面的UHPC端部模壳板，所述UHPC端部模壳板横桥向固定连接在各相邻型钢端之间的间隔处。加工方法及应用用上述的型钢‑UHPC桥面预制板进行。本申请通过在各个型钢端部的间隔处设置有UHPC端部模壳板，增强型钢‑UHPC组合桥面预制板在纵向端部的横向联系，从而提高型钢‑UHPC组合桥面预制板在吊装时的横向抗弯以及抗裂的能力。
