A transverse limit cable clamp

By installing lateral limiting cable clamps on a single-span suspension bridge and adjusting the lateral spacing of the main cables, the problems of increasing the lateral width of the bridge and the difficulty of horizontal alignment design were solved, thus achieving bridge width compression and design simplification.

AI Technical Summary

Technical Problem

When a single-span suspension bridge adopts a central underpass and combined anchorage scheme, the main cable passing under the bridge deck increases the lateral width of the bridge and makes the design of the bridge's horizontal alignment more difficult.

Method used

Lateral limiting cable clamps are used to apply lateral constraints to the two main cables through the connection structure of the left and right cable clamps, thereby adjusting the lateral spacing of the main cables, reducing the bridge width and simplifying the horizontal alignment design.

Benefits of technology

It achieves the compression of the bridge's lateral width, reduces the difficulty of bridge planar alignment design, and has the advantages of simple construction, easy installation, and high constraint efficiency.

Abstract

This application relates to a lateral restraint cable clamp, which includes a left cable clamp, a right cable clamp, and a connecting structure connecting the left and right cable clamps, all installed on two main cables. The left cable clamp has a first ear plate, and the right cable clamp has a second ear plate. The connecting structure includes at least one pair of first splicing plates, with the first ear plate of the left cable clamp and the second ear plate of the right cable clamp clamped between the two first splicing plates. This invention provides a lateral restraint cable clamp that connects the left and right cable clamps installed on two main cables via a connecting structure where the first ear plate of the left cable clamp and the second ear plate of the right cable clamp are clamped between the two first splicing plates. This applies lateral restraint to the two main cables to adjust the lateral spacing between them in mid-air, thereby compressing the lateral width of the main cables passing under the bridge deck and reducing the adverse effects of the central underpass design on the main cable.
