Description

Tensioning rod piece for high-strength traffic track Technical Field The utility model relates to the technical field of traffic tracks, in particular to a tensioning rod for a high-strength traffic track. Background With the acceleration of the urban process and the continuous development of high-speed railways, the construction scale of urban rail transit and high-speed railways is increasingly enlarged. In the track traffic construction, the application of structural components such as track slabs, sleepers, precast beams and the like is becoming wider and wider, the components need to stretch prestressed tendons in an internal steel reinforcement cage in the production process so as to improve the compression resistance, rigidity and durability of the structure, and the importance of stretch-draw bars as key components for realizing the stretch-draw of the prestressed tendons is becoming increasingly prominent. Most of the tensioning rod pieces used at present are difficult to prevent the tensioning rod from being broken, the strength of the tensioning rod is difficult to strengthen, the practicability of the tensioning rod piece is poor, the reinforcing ribs are difficult to install on the tensioning rod piece, and the installation firmness of the tensioning rod piece is poor. Disclosure of utility model The utility model aims to provide a tensioning rod for a high-strength traffic track, which aims to solve the problems in the prior art. In order to achieve the purpose, the tensioning rod for the high-strength traffic track comprises a tensioning rod body and a reinforcing rib body, wherein an anti-fracture reinforcing mechanism is arranged on the outer wall of the tensioning rod body, the anti-fracture reinforcing mechanism comprises a first nut, the first nut is arranged on the outer wall of the tensioning rod body, a supporting plate is arranged on the outer wall of the first nut, a rotating shaft is fixedly connected to the inner side of the supporting plate, a rotating rod is arranged on the outer wall of the rotating shaft, mounting frames are arranged on two sides of the rotating rod, threaded holes are formed in the mounting frames, and first bolts are arranged on the inner walls of the threaded holes.
