Steel-concrete composite beam bridge floor continuous structure adopting annular joints
The invention belongs to the technical field of bridge engineering, and particularly relates to a steel-concrete composite beam bridge floor continuous structure adopting annular joints. According tothe invention, connecting steel plates are welded on end cross beam top plates on two sides after end cross beams are erected and shearing force nails are symmetrically distributed on the shear wall;the bridge floor continuous structure is characterized in that the bridge floor continuous structure further comprises longitudinal annular steel bars, annular connecting steel bars and bridge floor continuous notches, the annular connecting steel bars and the longitudinal annular steel bars extending out of the bridge floors on the two sides are correspondingly arranged in a ring, butt welding staggered joint connection is adopted, and UHPC ultrahigh-strength joint concrete is poured in the bridge floor continuous grooves; the steel-concrete composite beam bridge floor continuous structure with the annular joints is simple in structure, convenient to construct and high in reliability, and the continuous connection strength of a bridge floor can be enhanced.
本发明属于桥梁工程技术领域，具体涉及到一种采用环状接缝的钢‑混凝土组合梁桥面连续构造；所述桥面连续构造在端横梁架设后将连接钢板焊接在两侧端横梁顶板上，并在其上对称布设剪力钉，其特征在于：所述桥面连续构造还包括纵向环状钢筋、环状连接钢筋和桥面连续槽口，环状连接钢筋与两侧桥面板伸出的纵向环状钢筋对应成环布置，并采用对接焊错缝连接，所述桥面连续槽内浇筑有UHPC超高强接缝混凝土；可增强桥面连续连接强度且构造简单、便于施工、可靠性高的一种环状接缝的钢‑混凝土组合梁桥面连续构造。
