A landscape suspension bridge and the anchoring method of its decorative cables

Abstract

The invention discloses a landscape suspension bridge and an anchoring method for a decorative cable thereof. A main cable is arranged on a bridge tower through a cable saddle frame, the tail end of the main cable is anchored on an anchorage structure at a bridge abutment, the anchorage structure includes a bridge abutment cushion cap, an anchorage on the outer side above the cushion cap and a side wall on the inner side above the cushion cap, and the cushion cap, the anchorage and the side wall completed by integrally pouring; the upper end of the suspender is fixed to the main cable on a design position by a cable clamp, and the lower end of the suspender is anchored to a beam through a longitudinal beam; the beam is an I beam, one end of the beam is pre-buried in a pier bent cap, and the other end of the beam is welded to a steel plate and is connected with a longitudinal beam body through bolts; the longitudinal beam is composed of two pieces of box iron, and the suspender is located between the two box iron and fixed by an upper pad, a lower pad and bolts; and the longitudinal beam is poured together with the suspender in concrete at the bridge abutment and the bridge tower. The landscape suspension bridge and the anchoring method avoid fixing the suspender to a side beam flange plate, reduce the adverse effect on the structure and have certain landscape and economic advantages; and the operation and maintenance is simple, and people can use conveniently.

Description

Technical field [0001] The invention belongs to the field of bridge engineering, and specifically relates to a landscape suspension bridge and a method for anchoring decorative cables thereof. Background technique [0002] Since ancient times, iconic landscape buildings have occupied prominent spatial positions and will be more easily recognized and regarded as important things. With the development of social economy, people's spiritual enjoyment level is getting higher and higher, and urban landscape bridges can bring people a visual experience. The decorative suspension cables of the landscape suspension bridge do not participate in the stress of the main bridge structure. In the construction process, the main structure of the bridge is generally constructed first, and then the bridge tower is constructed. The main cable is erected on the bridge tower through the saddle on the bridge tower. The end of the cable is anchored on the anchor, and finally the construction of the boo...

AI Technical Summary

Problems solved by technology

[0003] In some landscape suspension bridges that have been built at present, the suspenders are fixed at the position of the flange plate of the side girder. The way the suspenders are fixed may have adverse effects on the beam body under the influence of various loads such as wind loads and vehicle loads, reducing the The safety and quality of the bridge; and the anchorage structure of the built bridge is relatively large, and the structural gravity of the abutment itself is not used to offset the tension of the main cable, resulting in complex construction, large engineering volume, and high cost.
