Steel strand tie bar cable system with layered and separated wire supporting structure and mounting method of steel strand tie bar cable system

Abstract

The invention relates to a steel strand tie-rod cable system with a layered and separated-wire supporting structure and an installation method.The steel strand tie-rod cable system comprises a left anchoring point engineering structure object and a right anchoring point engineering structure object, anchorage devices are arranged on the anchoring point engineering structure objects, a steel strand cable body is installed between the left anchorage device and the right anchorage device in a penetrating mode, and each anchorage device comprises a plurality of conical anchoring holes; the steel strand cable body comprises a plurality of steel strands, the steel strands correspond to the conical anchoring holes in a one-to-one mode, anchoring clamping pieces are embedded in the conical anchoring holes in a wedged mode, the steel strands are fixed to an anchorage device through the anchoring clamping pieces, and a plurality of supporting frames are arranged on the steel strand cable body at intervals in the left-right direction. According to the invention, not only can the requirements of mounting, tensioning and replacing a single steel strand through a cable be met, but also the function of mechanical circulating cable penetration can be realized.

Description

technical field [0001] The invention relates to an external prestressed tie rod cable and an installation method of an arch bridge, in particular to a steel strand tie rod system and an installation method with a layered split wire support structure. Background technique [0002] Arch bridges, as a type of bridge spanning rivers, are widely used in the field of modern bridge construction. Tie-rod arch bridges with external prestressed tie rods can balance the horizontal thrust of the structure through cables, and have the advantages of beautiful appearance and strong spanning ability. [0003] The tie rod cables that use prestressed steel strands as the stressed tendons are often provided with wire splitting plates or wire splitting rings, so that each steel strand of the tie rod rope is parallel and independent of each other, so it has the ability to pass through a single cable, a single wire The advantages of lightweight construction of pulling and single replacement make ...

AI Technical Summary

Problems solved by technology

Especially when the tie rods are located inside the main girder box structure, it is very labor-intensive and man-hour;

[0005] 2. When the tie rods adopt large specifications, due to the large number of steel strands, the labor intensity of cable threading construction is high
