Prefabricated bridge deck slab joint structure without embedded steel bars and construction method thereof
The invention discloses a prefabricated bridge deck slab joint structure without embedded steel bars and a construction method thereof, and particularly relates to the technical field of bridge engineering. The prefabricated bridge deck slab joint structure comprises two prefabricated bridge deck slabs, two embedded steel members, high-strength bolts, bent steel bars, transverse penetrating steel bars, post-pouring concrete and longitudinal steel bars; a plurality of mounting holes are formed in the two embedded steel members, the mounting holes are distributed in the upper parts and the lower parts of the embedded steel members, the two embedded steel members are fixedly connected through high-strength bolts, and the two ends of the longitudinal steel bars penetrate through the interior of the prefabricated bridge deck correspondingly. According to the scheme, the embedded steel bars in the prefabricated bridge deck slab are omitted, and the collision problem of the embedded steel bars during joint connection is avoided; welding is not needed, connection of the steel bars at the joints can be completed through binding, and the construction period is greatly shortened; dry joints and wet joints are effectively combined, the integrality is good, and the arrangement of the bent steel bars enables the force transmission path at the joints to be clearer.
本发明公开了一种取消预埋钢筋的预制桥面板接缝构造及其施工方法，具体涉及桥梁工程技术领域，包括两个预制桥面板、两个预埋钢构件、高强螺栓、弯折钢筋、横向贯穿钢筋、后浇混凝土和纵向钢筋，两个所述预埋钢构件的内部开设有若干个安装孔，所述安装孔分布于预埋钢构件的上下两部分，两个所述预埋钢构件之间通过高强螺栓固定连接，所述纵向钢筋的两端分别贯穿预制桥面板的内部。上述方案中，取消了预制桥面板中的预埋钢筋，避免了接缝连接时预埋钢筋的碰撞问题；无需焊接，通过绑扎即可完成接缝处钢筋的连接，大大缩短了施工周期；有效结合了干接缝与湿接缝，整体性较好，弯折钢筋的设置使接缝处传力路径更加明确。
