Steel-concrete combined embedded thrust structure of cable-stayed bridge guyed cable hanging basket
The invention relates to the technical field of cable-stayed bridge construction, in particular to a steel-concrete combined embedded thrust structure of a cable-stayed bridge guyed cable hanging basket, and aims to solve the technical problem that an existing thrust structure of the cable-stayed bridge guyed cable hanging basket can cause adverse effects on clearance under a bridge and attractiveness of the bridge. The following technical scheme is adopted: the structure comprises a box girder and a hanging basket; the box girder is provided with a box girder bottom plate; the hanging basketis provided with a hanging basket bottom beam; a preformed hole is formed in the bottom plate of the box girder; a thrust block located on the edge of the preformed hole is arranged in the box girder;a shear block is fixed to the bottom beam of the hanging basket; the upper end of the shear block penetrates through the preformed hole to extend into the box girder; and the shear block abuts against the surface of the thrust block under the horizontal component action of a guy rope.
本发明涉及斜拉桥施工技术领域，具体是一种斜拉桥牵索挂篮钢混结合内嵌式止推结构，旨在解决现有斜拉桥牵索挂篮止推结构会对桥下净空和桥梁美观造成不良影响的技术问题。采用如下技术方案：包括箱梁和挂篮，箱梁设有箱梁底板，挂篮设有挂篮底梁，箱梁的底板设有预留孔，箱梁内设有位于预留孔边缘的止推块，挂篮的底梁上固定有剪力块，剪力块的上端穿过预留孔伸入箱梁内部，且在牵索的水平分力作用下，剪力块抵靠在止推块表面。
