Fabricated steel-concrete composite beam section adopting R-UHPC transverse rapid connection and construction method of fabricated steel-concrete composite beam section
The invention belongs to the technical field of steel-concrete bridges, and particularly relates to a fabricated steel-concrete composite beam section adopting R-UHPC transverse rapid connection and a construction method of the fabricated steel-concrete composite beam section. The invention provides an assembly type steel-concrete composite beam section adopting R-UHPC transverse rapid connection, which structurally comprises a steel-concrete section, a concrete section, an embedded steel bar, a UHPC cast-in-place block, a combined connecting plate unit and a transverse bridge direction prestressed steel strand, so that the transverse bridge direction of the steel-concrete composite beam section is upward, and the transverse bridge direction of the steel-concrete composite beam section is upward; the UHPC cast-in-place blocks, the combined connecting plate units and the transverse-bridge-direction prestressed steel strands form an integral connecting mode with relatively high connecting strength, and the requirement of a large-span steel-concrete bridge for the structural strength of the steel-concrete composite beam section is met.
本发明属于钢混桥梁技术领域，尤其涉及一种采用R‑UHPC横向快速连接的装配式钢混结合梁段及其施工方法。本发明提供一种采用R‑UHPC横向快速连接的装配式钢混结合梁段，其结构组成包括：钢混段、混凝土段、预埋钢筋、UHPC现浇块、组合连接板单元，以及横桥向预应力钢绞线，使得：该钢混结合梁段的横桥向上，UHPC现浇块、组合连接板单元和横桥向预应力钢绞线组成一个连接强度相对较大的整体连接方式，满足大跨度钢混桥梁对钢混结合梁段的结构强度需求。
