Cast-in-place joint structure of UHPC beam plate with embedded reinforcing steel components and construction method thereof
The invention discloses a cast-in-place joint structure of a UHPC beam plate with embedded reinforcing steel components. The structure comprises a pair of adjacently-arranged prefabricated UHPC beam plates and a cast-in-place UHPC joint cast in place between the pair of prefabricated UHPC beam plates, wherein the bottom of each prefabricated UHPC beam plate is fixedly provided with an embedded reinforcing steel component extending to the cast-in-place UHPC joint, and the end parts of the adjacent embedded reinforcing steel components are fixedly connected; and the side wall of the end part ofthe prefabricated UHPC beam plate is provided with a latticed groove. The invention further provides a construction method of the cast-in-place joint structure of the UHPC beam plate with the embeddedreinforcing steel components. According to the invention, through the mutual synergistic effect of the latticed grooves and the embedded reinforced steel components, the latticed grooves and the embedded reinforced steel components are mutually matched, so that the problem of weak stress of the UHPC bridge deck wet joint connection can be effectively solved, the stress performance of the new andold UHPC interfaces is remarkably improved, the interfaces cannot crack under the action of service load, and the durability and the service performance of the structure are improved.
本发明公开了一种带预埋加强钢部件的UHPC梁板现浇接缝构造，包括一对相邻设置的预制UHPC梁板和现浇于一对所述预制UHPC梁板之间的现浇UHPC接缝，所述预制UHPC梁板底部固设有向现浇UHPC接缝处延伸的预埋加强钢部件，相邻所述预埋加强钢部件的端部固接；所述预制UHPC梁板端部的侧壁设有网格状凹槽。本发明还提供一种上述带预埋加强钢部件的UHPC梁板现浇接缝构造的施工方法。本发明通过网格状凹槽与预埋加强钢部件相互协同作用，二者相互配合，能有效解决UHPC桥面板湿接缝连接受力薄弱的问题，新旧UHPC界面受力性能得到显著提升，界面在使用荷载作用下不会开裂，提高结构的耐久性和使用性能。
