Prefabricated transverse prestress bridge deck slab and bridge
The invention discloses a prefabricated transverse prestress bridge deck slab and a bridge, the prefabricated transverse prestress bridge deck slab comprises a prefabricated reinforced concrete slab,the prefabricated reinforced concrete slab comprises a concrete slab body, a transverse reinforcing steel bar assembly, a longitudinal reinforcing steel bar assembly and a transverse prestress steel strand assembly; the transverse steel bar assembly and the longitudinal steel bar assembly are distributed in a crossed mode to form a reinforcing steel bar net in the concrete slab body. The transverse prestress steel strand assembly is arranged in a staggered single-end tensioning mode. Transverse prestress steel strands are tensioned in a staggered single-end tensioning mode, so that the stressdifference between the two ends caused by single-end tensioning is reduced, and the anti-cracking capacity of the prefabricated reinforced concrete slab can be remarkably improved.
本发明公开了一种预制装配式横向预应力桥面板及桥梁，预制装配式横向预应力桥面板，包括：预制钢筋混凝土板，预制钢筋混凝土板包括混凝土板体、横向钢筋组件、纵向钢筋组件和横向预应力钢绞线组件；横向钢筋组件和纵向钢筋组件交叉分布，在混凝土板体内形成加强钢筋网；横向预应力钢绞线组件采用交错单端张拉方式设置。横向预应力钢绞线采用交错单端张拉的方式进行张拉，以降低单端张拉引起的两端应力差，可以显著提高预制钢筋混凝土板的抗裂能力。
