Prefabricated bridge deck slab joint connecting structure and construction method thereof
The invention discloses a prefabricated bridge deck slab joint connection structure and a construction method thereof.The structure comprises two prefabricated bridge deck slabs with the end faces in butt joint, and a first round steel pipe and a second round steel pipe which are located on the same axis in the longitudinal direction are embedded in the end faces of the two prefabricated bridge deck slabs correspondingly; a deformed steel bar which stretches across the joint between the end faces of the bridge deck slab is arranged in the first round steel pipe and the second round steel pipe, the two ends of the deformed steel bar are anchored in the first round steel pipe and the second round steel pipe respectively, and cement mortar used for filling pipe cavities and wrapping the deformed steel bar is poured in the first round steel pipe and the second round steel pipe. According to the prefabricated bridge deck slab joint connecting structure and the construction method thereof, the overall stress performance and the anti-cracking performance are good; meanwhile, the joint connecting structure and the construction method thereof have the advantages of being high in assembly efficiency, convenient to prefabricate, easy to construct, low in manufacturing cost and high in assembly efficiency.
本发明公开了一种预制桥面板接缝连接构造及其施工方法，构造包括两个端面处对接的预制桥面板，两个所述预制桥面板端面处分别预埋有沿纵向位于同一轴线的第一圆钢管和第二圆钢管，所述第一圆钢管和第二圆钢管中设置有一条横跨桥面板端面间接缝且两端分别锚固于第一圆钢管和第二圆钢管内的螺纹钢棒，所述第一圆钢管和第二圆钢管中浇灌有填充管腔及包裹螺纹钢棒的水泥砂浆。本发明公开的预制桥面板接缝连接构造及其施工方法具有较好的整体受力性能与抗裂性能；同时该种接缝连构造及其施工方法具有较高的装配效率，且预制方便，施工简易，造价低廉，具有较高的装配效率。
