Prefabricated bridge deck slab and composite beam hogging moment area structure
The invention relates to a prefabricated bridge deck slab and composite beam hogging moment area structure which comprises a bottom plate, a plurality of perforated plates are fixed to the top of the bottom plate, the perforated plates are distributed at intervals in the longitudinal bridge direction, the length direction of the perforated plates extends in the transverse bridge direction, a plurality of reserved holes are formed in the perforated plates at intervals in the transverse bridge direction, and the reserved holes are formed in the top of the bottom plate. First longitudinal steel bars are mounted in the preformed holes; the prefabricated concrete slab is arranged at the top of the bottom plate, a plurality of longitudinal prestressed tendons and a reinforcing mesh are embedded in the prefabricated concrete slab, and the longitudinal prestressed tendons are distributed at intervals in the transverse bridge direction. Traditional transverse prestressed tendons are replaced by the perforated plates, the thickness of the prefabricated bridge deck can be reduced, the tensile strength of the prefabricated bridge deck in the transverse bridge direction can be guaranteed through the perforated plates, only a small amount of wet connection operation is needed on site during follow-up composite beam construction, longitudinal and transverse prestressed tendons in a hogging moment area do not need to be tensioned, construction is simple, and the construction speed is high.
本申请涉及一种预制桥面板及组合梁负弯矩区结构，其包括：底板，所述底板的顶部固定有多个开孔板，多个所述开孔板沿纵桥向间隔分布，且所述开孔板的长度方向沿横桥向延伸设置，所述开孔板沿横桥向间隔开设有多个预留孔，所述预留孔内安装有第一纵向钢筋；预制混凝土板，所述预制混凝土板设置于所述底板的顶部，且所述预制混凝土板内埋设有多个纵向预应力筋和钢筋网，多个所述纵向预应力筋沿横桥向间隔分布。通过开孔板替代传统的横向预应力筋，可减薄预制桥面板的厚度，且开孔板可保证预制桥面板沿横桥向抗拉强度，在后续组合梁施工时，现场仅需少量湿接作业，无需张拉负弯矩区纵、横向预应力筋，施工简单，施工速度快。
