Modular ultra-high performance concrete prefabricated assembled beam suitable for different spans
The invention belongs to the technical field of bridge engineering, and discloses a modular ultra-high performance concrete prefabricated assembled beam suitable for different spans. The prefabricatedassembled beam is formed by splicing side support units located at the two ends of the prefabricated assembled beam and at least one standard unit located between the two side support units. First steering devices are arranged at the bottoms of webs at the spliced positions of the standard units and the side support units and used for allowing high-strength prestressed reinforcements to penetratethrough. The other end of the side support unit is pre-embedded with a prestressed steel beam pipeline for the high-strength prestressed reinforcements to extend out on the web, and the outlet end ofeach prestressed steel beam pipeline is provided with an anchoring device for anchoring the high-strength prestressed reinforcements; the number of the high-strength prestressed reinforcements penetrating through the prefabricated main beam units is determined according to the structural strength of the prefabricated assembled beam. The prefabricated main beam units are convenient to prefabricateand transport in factories, the side support units, the standard units and the middle support units can be freely selected to be matched and combined according to the span of the bridge, the number of the high-strength prestressed reinforcements can be changed, and modular configuration of the bridge is achieved.
本发明属于桥梁工程技术领域，公开一种适应不同跨径的模数式超高性能混凝土预制拼装梁，其包括位于预制拼装梁两端的边支座单元和位于两个边支座单元之间的至少一个标准单元拼接而成，标准单元和边支座单元在相互拼接处的腹板底部处均设有第一转向装置供高强预应力钢筋穿过，边支座单元另一端在腹板上预埋有供高强预应力钢筋伸出的预应力钢束管道，预应力钢束管道出口端设有锚固装置对高强预应力钢筋进行锚固；贯穿各预制主梁单元的高强预应力钢筋数量根据预制拼装梁结构强度确定。本发明的预制主梁单元便于工厂预制和运输，可根据桥梁跨度自由选择边支座单元、标准单元、中支座单元搭配组合，变换高强预应力钢筋数量即可，实现桥梁的模数式配置。
