Prefabricated bridge deck slab and assembly type composite beam comprising prefabricated bridge deck slab
The invention discloses a prefabricated bridge deck slab and an assembly type composite beam comprising the prefabricated bridge deck slab, and relates to the field of bridge engineering. The prefabricated bridge deck slab comprises a prefabricated bridge deck slab body, a concave-convex shear groove with a downward opening is formed in the bottom of the haunching position of the prefabricated bridge deck slab body, the two longitudinal ends of the concave-convex shear groove are open, and the concave-convex shear groove is provided with a full-length grouting hole and a full-length grouting hole in the thickness direction of concrete; the fabricated composite beam comprises a prefabricated bridge deck slab, the bottom of the prefabricated bridge deck slab is fixedly connected with a steel beam, and an upper flange of the steel beam is located at the concave-convex shear groove. According to the method, weakening of the cross section caused by hole opening of the prefabricated bridge deck is avoided, it is guaranteed that position conflicts between steel bars and welding studs cannot occur when the bridge deck is installed, and therefore the construction quality is improved, and the construction speed is increased.
本发明公开一种预制桥面板及包含该预制桥面板的装配式组合梁，涉及桥梁工程领域；该预制桥面板包括预制桥面板本体，所述预制桥面板本体加腋处的底部设置有开口向下的凹凸剪力槽，所述凹凸剪力槽纵向两端开口，且所述凹凸剪力槽沿混凝土厚度方向开设有通长的灌浆孔和冒浆孔；该装配式组合梁包括预制桥面板，所述预制桥面板底部固定连接有钢梁，所述钢梁的上翼缘位于所述凹凸剪力槽处；本发明避免了预制桥面板开孔对于截面的削弱，确保安装桥面板时不会出现钢筋与焊钉的位置冲突，从而提高了施工的质量和速度。
