The invention provides an externally-wrapped UHPC steel-concrete superposed monorail beam which comprises an UHPC steel-concrete structure and a steel box beam structure connected to the lower portion of the UHPC steel-concrete structure, the UHPC steel-concrete structure comprises a steel shell and externally-wrapped UHPC wrapping the steel shell and extending out of the two sides of the lower portion of the steel shell to form a walking panel, and shear key connecting grooves are formed in the bottom of the walking panel; a shear key is arranged on the top of the steel box girder structure, and in the assembled state, the shear key is matched with the shear key connecting groove. According to the externally-wrapped UHPC steel-concrete superposed monorail beam, the shear keys are arranged at the top of the steel box beam structure, and the shear key connecting grooves are formed in the bottom of the walking panel, so that the UHPC steel-concrete structure can be connected with the steel box beam structure, and the externally-wrapped UHPC steel-concrete superposed monorail beam has the advantages of being fast in construction and reasonable in structural stress. In addition, the UHPC steel-concrete structure is externally wrapped with UHPC to form a concrete bridge deck, and the functions of train walking and guiding can be achieved.
本发明提供了一种外包UHPC钢‑混叠合单轨梁，包括UHPC钢‑混结构以及连接到UHPC钢‑混结构下方的钢箱梁结构，其中，UHPC钢‑混结构包括钢壳和包覆钢壳、并在钢壳下方两侧伸出而形成行走面板的外包UHPC，行走面板的底部设置有剪力键连接槽；钢箱梁结构的顶部设置有剪力键，在组装好的状态下，剪力键与剪力键连接槽配合。该实施方式通过本发明的一种外包UHPC钢‑混叠合单轨梁，通过在钢箱梁结构顶部设置剪力键，在行走面板底部设置剪力键连接槽，使得UHPC钢‑混结构能够与钢箱梁结构相连接，具有施工快、结构受力合理的特点。此外，UHPC钢‑混结构通过外包UHPC，形成混凝土桥面板，可以满足列车行走和导向的功能。
