AI Technical Summary

Technical Problem

In the construction of self-anchored suspension bridges, the main cable strands in the cable sleeve are not restricted by external forces and the cable is not tightened, resulting in a large gap ratio, making it difficult to install the upper half of the cable sleeve, which affects the construction progress.

Method used

A limiting device is designed, consisting of a limiting steel plate at the back end of the short cable sleeve, a limiting steel plate at the front end of the short cable sleeve, a lower half of the short cable sleeve and an upper half of the short cable sleeve. Through the precise positioning and fixing of these components, the correct position and tightness of the main cable strand is ensured.

Benefits of technology

The accurate positioning and installation of the main cable strand is achieved, the void ratio is reduced, the installation process of the upper half of the loose cable strap is simplified, and the construction efficiency is improved.

Abstract

The utility model discloses a limiting device for assisting in positioning a main cable strand at a splay sling, which consists of a splay sling rear end limiting steel plate, a splay sling front end limiting steel plate, a lower half splay sling and an upper half splay sling, the upper half splay sling covers the lower half splay sling, and the upper half splay sling and the lower half splay sling are fixed together by a screw. And the main cable strand is wrapped. Compared with the prior art, the auxiliary positioning device has the advantages that (1) the auxiliary positioning function of the main cable strand at the splay sling can be realized, and the problems that after the main cable strand is installed, the void ratio is large, and the upper half splay sling is difficult to install are solved; (2) the structure is simple, the processing and the installation are convenient, and the practicability is strong; and (3) the device can be suitable for the installation of main cable strands of most self-anchored suspension bridges adopting a splay cable sling structure, and is wide in application.
