Problems solved by technology

Limited by the processing method, the stainless steel protective tube cannot meet the thickness requirement of 1mm and above
Therefore, in the actual construction process of the bridge, it is easy to be knocked and collapsed by human beings. Over time, it not only loses its protective effect but also seriously affects the appearance of the bridge.

Abstract

The invention relates to a sheath for a bridge cable. The sheath comprises a hollow pipe body, wherein the pipe body is formed by a first arc-shaped plate piece and a second arc-shaped plate piece which are matched with each other; connection plates are respectively arranged at the long edges of the two sides of the first arc-shaped plate piece; the first arc-shaped plate piece is fixedly connected with the second arc-shaped plate piece through the two connection plates. The sheath is simple in structure and convenient to manufacture; the thickness of the sheath is increased from 0.5mm to 1mm or more; the pipe body consists of the two arc-shaped plate pieces which are matched with each other, so that the sheath is convenient to mount, and the possibility of collapse is low in a mounting process.

Description

technical field [0001] The invention belongs to the technical field of bridge cables, and in particular relates to a sheath for bridge cables. Background technique [0002] The cable is the lifeline of the bridge. How to effectively protect the safety of the cable during use, especially the protection of the cable near the bridge deck, is the focus of bridge designers. Generally, hot-extruded polyethylene is used for the outer layer of bridge cables to protect the cables, and the exposed polyethylene requires a sheath to be installed within a certain height range above the bridge deck at the beam end to prevent artificial damage and meet the bridge landscape requirements. [0003] At present, the above-mentioned sheath is mainly made of stainless steel protective tube, the wall thickness of which is 0.5mm, which is formed by bending, and the edge connection is buckled. Limited by the processing method, the stainless steel protective tube cannot meet the thickness requiremen...
