Pulling-rope diverter for inclination of rope tower

Abstract

The invention discloses a pulling-rope diverter for inclination of a rope tower. The pulling-rope diverter comprises saddle bodies and rope-strand transition pipes connected by transition flanges, wherein wire distributing pipes arranged in the saddle bodies adopt raindrop-shaped wire distributing pipes; wire-distributing-pipe positioning plates are provided with raindrop-shaped holes; rope-strand guiding sections are arranged between the two ends of the saddle bodies and the transition flanges; each rope-strand guiding section consists of a saddle-body connecting flange, a wire-distributing-pipe transition plate, a guide pipe connecting flange, a guide pipe, a wire pipe, a wire pipe positioning plate and a guide pipe transition plate; the guide pipe is internally provided with the wire pipe positioned by the wire pipe positioning plate; one end of the wire pipe is respectively inserted into a pipe hole arranged on the wire distributing pipe transition plate; the pipe hole arranged on the wire-distributing-pipe transition plate corresponds to the raindrop-shaped hole arranged on the wire-distributing-pipe positioning plate; the wire-distributing-pipe transition plate is connected between the connecting flange and the guide pipe connecting flange; the other end of the wire pipe is inserted into the pipe hole arranged on the guide pipe transition plate at the end part of the guide pipe; and the guide pipe transition plate is arranged in the transition-section flange. The pulling-rope diverter disclosed by the invention has the advantage that the saddle bodies are anchored in the rope tower by adopting a manner of oblique intersection.

Description

technical field [0001] The invention relates to a cable diverter used for obliquely placing a cable tower, and belongs to the technical field of bridge engineering anchors. Background technique [0002] The cable tower is a tower-shaped structure supporting the main cable of a suspension bridge or a cable-stayed bridge. Most of the long-span cable-stayed bridges use concrete box-shaped cable towers to anchor the cables, and the cables are often anchored in a point-symmetrical way. Point symmetric anchor cables are the main ones. [0003] The internal tooth block method directly anchors the cable to the concrete tooth block on the inner wall of the tower with anchorage, and applies hoop prestress in the tower wall in the anchorage area. In the steel anchor box method, the stay cables are anchored to the steel anchor box connected to the tower wall through shear studs. The steel anchor beam method anchors the stay cable to the steel anchor beam placed at the corbel of the t...

Problems solved by technology

But this straddle-type saddle is owing to integral pouring molding, and saddle does not have extension section, so not only processing is difficult, and makes the straight section of saddle too long, can produce splitting force to tower wall, thereby Affect the safety of the cable tower; when this kind of saddle is buried deep in the cable tower, it will also increase the cost
