Stay cable structure of multifunctional cable-stayed bridge

Abstract

The invention provides a stay cable structure of a multifunctional cable-stayed bridge, which comprises a bridge main body, a bridge tower body, a top cover, a first traction hole, a traction seat, a rotatable traction support rod structure, a connectable buffer adjusting frame structure, a tractable rotary adjusting frame structure, a liftable jacking auxiliary block structure, an auxiliary rope, an inserting pin shaft, a first fixing groove, a first rotating rod and a rotating block, and a deep groove ball bearing and a square-head nut. Through the arrangement of the connecting frame, the inclined T-shaped seat, the second rotating rod, the connecting hole, the connecting frame, the fixing hole and the inclined T-shaped frame, the cable-stayed adjustment work can be conveniently carried out in the using process through the threaded connection arrangement of the second rotating rod and the inclined T-shaped frame in the using process; and through arrangement of a connecting frame, a fixing hole, an inclined T-shaped frame, a sliding hole, a buffer spring and a second rotating rod, the inclined T-shaped frame can be conveniently pushed through the buffer spring in the using process, and buffering and tensioning work can be conveniently conducted in the cable-stayed process.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, in particular to a cable-stayed cable structure of a multifunctional cable-stayed bridge. Background technique [0002] Cable-stayed bridges are a commonly used structural form of long-span bridges, and the layout of their cable-stayed cables is mostly planar. Due to its mechanical and geometric characteristics, stay cables are extremely susceptible to significant vibrations due to wind, earthquake, traffic loads and other factors. [0003] But existing stay cable structure still exists in the process of carrying out inconvenient adjustment work, inconvenient in the process of using buffering and tensioning work and inconvenient to carry out rotation connection in the process of using and inconvenient in the process of using Problems with auxiliary installation during use. [0004] Therefore, it is very necessary to invent a cable-stayed structure of a multifunctional cable-stayed bri...
