Steel strand finished cable

Abstract

The invention relates to a steel strand finished cable. The steel strand finished cable solves the problems that in the prior art, the end of a cable body is anchored on a site, so that the influenceof the site construction environment is large, and the anchoring quality cannot meet design ideal requirements. The steel strand finished cable comprises the cable body stranded through a plurality ofsteel strands and an anchoring structure connected to the end of the cable body; an extruding sleeve is fixed to the end of each steel strand, and the anchoring structure comprises an anchoring sleeve, a supporting plate arranged in the anchoring sleeve and bond materials, wherein the anchoring sleeve is filled with the bond materials; and the end of the extruding sleeve makes contact with the supporting plate, and the cable body and the anchoring sleeve are directly anchored in a factory and filled with the bond materials to form the finished cable. The cable body and the anchoring sleeve are directly anchored in the factory to form the finished cable, the finished cable can be directly used and mounted on the site, anchoring for the end of the cable body is not required, anchoring and anti-corrosion work can be completed in the factory, the anchoring quality is good, anti-corrosion performance is good, the site construction requirements are simplified, and the construction progressis accelerated.

Description

technical field [0001] The invention belongs to the field of engineering structure zippers, in particular to a steel strand finished cable. Background technique [0002] At present, bridges, stadiums and other buildings in my country are mostly supported by cables. The cables mainly include cold-cast anchor cables, hot-cast anchor cables and clip-type anchor cables. However, in large-scale building structures, steel structure cable-stayed bridges and arch bridges, due to structural constraints, it is required to use a cable guide with a smaller inner diameter. Traditional cold-cast anchor wire cables, hot-cast anchor wire cables and steel strand group anchor cables are difficult to meet this requirement due to the large size of the anchor head, and the cost is relatively high. [0003] The ends of the current cables are mostly fixed with clips or extrusion sleeves, but no matter what structure is used for the end fixation, the anchoring of the ends of the cable body is carr...

AI Technical Summary

Problems solved by technology

[0005] The invention solves the defect that the end of the cable body is anchored on site in the prior art, which is greatly affected by the construction environment on site, and the anchoring quality cannot meet the ideal design requirements. It provides a finished steel strand cable that can be directly installed in the factory. After the processing of the body and the anchoring end, the finished cable is formed and installed directly on the construction site, so as to ensure the quality of the anchoring end of the cable body

[0006] The present invention also solves the defects in the prior art that the outer surface of the end of the cable body is threaded for connection, which causes the length of the cable body to be limited, and the external thread increases the difficulty of anti-corrosion, and provides a steel strand finished cable, the end of the cable body The extrusion sleeve is used for connection without external thread processing, which reduces the difficulty of corrosion protection. The anchor sleeve is equipped with a support plate, which supports the extrusion sleeve to bear the axial force, and the anchor sleeve is filled with gripping material to increase the external axial force of the steel strand. resistance, thereby improving the anchoring effect of the overall anchoring end
