An improved bridge cable structure and its hanging method

Abstract

The invention discloses an improved bridge inhaul cable structure. The improved bridge inhaul cable structure comprises a plurality of sets of stay cables, each stay cable set comprises two symmetric stay cables, a first damper is arranged between the two stay cables in the same set, each first damper comprises a first damper shell, an inner rubber layer is arranged in each first damper shell, two through holes allowing the two stay cables in each set to penetrate are formed in the corresponding inner rubber layer, locking clamps are arranged at the two ends of the damper shells, second dampers are arranged between the adjacent stay cable sets, any two stay cables in different sets are bound together through the second dampers, the second dampers comprise rubber sleeve rings, two elastic metal rings are arranged in each rubber sleeve ring in a cross mode, the two elastic metal rings in each rubber sleeve ring are welded together, the two ends of the stay cables are fixed through anchor point mechanisms, and telescopic adjusters are arranged on the stay cables respectively. The defects in the prior art can be overcome, the inhaul cable structure is simplified, and hanging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an improved bridge cable structure and a hanging method thereof. Background technique [0002] With the continuous development of bridge technology, cable-stayed bridges are widely used as one of the main types of long-span bridges, and their construction spans are increasing day by day. As a result, the capping force of the cable-stayed cable increases, and the difficulty of on-site construction and the investment in equipment continue to increase. Chinese invention patent CN 102444086 B discloses a bridge stay cable hanging system and a bridge stay cable hanging method. When hanging the cable, the traction force is small and the outer PE sheath of the stay cable is not easily damaged. However, such a cable structure uses a large number of cables, and the pulling and fixing force is not easy to adjust flexibly, resulting in a relatively complicated adjustment proces...

AI Technical Summary

Problems solved by technology

However, this kind of cable structure uses a large number of cables, and the pulling and fixing force is not easy to adjust flexibly, which makes the adjustment process of the cables more complicated when hanging.
