Joint structure of NC-UHPC hybrid rigid frame bridge, hybrid rigid frame bridge and construction method of hybrid rigid frame bridge
The invention discloses a joint structure of an NC-UHPC hybrid rigid frame bridge, the hybrid rigid frame bridge and a construction method of the hybrid rigid frame bridge. The hybrid rigid frame bridge comprises common concrete beam sections and ultra-high performance concrete beam sections, the ultra-high performance concrete beam sections are midspan beam sections, and the two ends of each ultra-high performance concrete beam section are connected with the corresponding common concrete beam section through the joint structure; the joint structure comprises a first connecting steel plate assembly, a second connecting steel plate assembly and a wet joint, and one end of the first connecting steel plate assembly is embedded in the end of a common concrete beam section and extends out of the end of the common concrete beam section; and one end of the second connecting steel plate assembly is embedded in the end of the ultra-high-performance concrete beam section and extends out of the end of the ultra-high-performance concrete beam section to be connected with the first connecting steel plate assembly. The hybrid rigid frame bridge solves the problems of midspan downwarping and web cracking of a common concrete large-span continuous rigid frame bridge, complex stress of a steel-concrete combined section of a common concrete-steel hybrid rigid frame bridge, and difficult maintenance of a steel box girder section.
本发明公开了一种NC‑UHPC混合刚构桥的接缝构造、混合刚构桥及其施工方法，混合刚构桥包括普通混凝土梁段和超高性能混凝土梁段，超高性能混凝土梁段为跨中梁段，超高性能混凝土梁段两端通过接缝构造分别与一普通混凝土梁段连接；接缝构造包括第一连接钢板组件、第二连接钢板组件和湿接缝，第一连接钢板组件一端预埋在普通混凝土梁段端部，并从普通混凝土梁段端部伸出；第二连接钢板组件一端预埋在超高性能混凝土梁段端部，并从超高性能混凝土梁段端部伸出与第一连接钢板组件连接。该混合刚构桥解决了普通混凝土大跨径连续刚构桥跨中下挠和腹板开裂问题以及普通混凝土‑钢混合刚构桥钢混结合段受力复杂、钢箱梁段养护难问题。
