Auxiliary device for fixing bridge cable and using method thereof

Abstract

The invention discloses an auxiliary device for fixing a bridge cable and a using method thereof. The auxiliary device comprises a rotating assembly, a guiding structure and a foundation anchor, a guiding rod is installed on one side of the interior of the foundation anchor, the guiding structure is slidably installed on one side of the guiding rod, and the rotating assembly is slidably installed on the side, away from the guiding rod, of the guiding structure; a tensioning nut is mounted in the center of the interior of the rotating assembly through a fixing screw, and a cable is connected to the interior of the tensioning nut through a threaded structure. The guiding rod is installed to guide the rotating assembly to move, a constructor can pull and tension the inhaul cable through a threaded structure, the constructor can conveniently adjust and control the tensioning force of stretching in the later period, pulling and tensioning are completed under the same structure, repeated operation of a user is avoided, and the operation process is shortened. And through cooperative use of the guiding structure and the rotating assembly, a constructor can conveniently and rapidly connect the foundation anchor and the cable, and the workload of the constructor is reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an auxiliary device for fixing bridge cables and a method for using the same. Background technique [0002] At present, there are mainly two types of cable-stayed cable systems commonly used in cable-stayed bridges in China. One is a semi-parallel steel cable protected by hot-extruded high-density polyethylene (PE) and a steel cable-stayed cable with a cold-cast pier anchor system; the other is One is to use parallel steel strands with different protections, outer HDPE sheath tube, and steel strands composed of special clip anchor systems at both ends. The stay cables of the two systems have their own protection characteristics. Parallel steel strands A single steel strand tension clip group anchor system is adopted. The single steel strand adopts protective measures such as hot-dip galvanizing, coating with special anti-corrosion grease or paraffin, hot-extruded PE c...
