Longitudinally-spliced steel-concrete mixed structure beam bridge
The invention discloses a longitudinally-spliced steel-concrete mixed structure beam bridge which comprises a steel box beam in a midspan area, a concrete beam in an end-span area and a steel-concrete connecting section used for connecting the steel box beam and the concrete beam, and the steel box beam and the concrete beam are fixedly connected through the steel-concrete connecting section. According to the longitudinally-spliced steel-concrete mixed structure beam bridge, the concrete beams are used in the end-spanning areas at the two ends of the bridge, the steel box beams are used in the midspan area needing to stretch across an expressway, the steel-concrete connecting sections are designed to connect the concrete beams and the steel box beams, the construction time of the midspan area is effectively shortened, and then traffic pressure is relieved; and the construction cost is reduced.
本发明公开了一种纵向拼接的钢砼混合结构梁桥,包括跨中区的钢箱梁、跨端区的混凝土梁和用于连接钢箱梁和混凝土梁的钢砼连接节段,所述钢箱梁和混凝土梁通过钢砼连接节段形成固定连接;本发明公开的纵向拼接的钢砼混合结构梁桥,桥的两端的跨端区使用混凝土梁,需要横跨高速公路的跨中区则使用钢箱梁,并设计钢砼连接节段来连接混凝土梁和钢箱梁,有效缩短了跨中区的施工时长,进而缓解了交通压力,降低了施工成本。
