Tower girder fixed-connection mechanism, corresponding cable-stayed bridge and building method of cable-stayed bridge
The invention discloses a tower girder fixed-connection mechanism, a corresponding cable-stayed bridge and a building method of the cable-stayed bridge. The tower girder fixed-connection mechanism is used for fixedly connecting a cable tower with a girder in the cable-stayed bridge. The tower girder fixed-connection mechanism comprises a cushion block and a fastening bolt, wherein the cushion block is installed between the cable tower and the girder, and a gap between the cable tower and the girder is filled through the cushion block. The fastening bolt sequentially penetrates through the cable tower, the cushion block and the girder and can apply pretightening force on the cable tower, the cushion block and the girder, and therefore the fixed-connection structure is formed between the cable tower and the girder to restrain the degrees of freedom in all directions. The tower girder fixed-connection mechanism has the advantages of being simple in structure, definite in stressing, high in adaptability, easy to assemble and disassemble, low in cost and the like, the time limit can be effectively saved, the manufacturing cost is lowered, and the construction risk is controlled.
