Multifunctional cable saddle

Abstract

A multifunctional cable saddle comprises a saddle body. Two ends of the saddle body respectively face a mid span and an anchor and are provided with a mid span end and an anchoring end, a supporting section saddle groove corresponding to the mid span end and a diverging section saddle groove corresponding to the anchoring end are formed in the saddle body and are in smooth transition in an extending direction of a main cable, and the saddle body integrates a main cable saddle supporting function and a dispersive cable saddle diverging function. The multifunctional cable saddle integrates the main cable saddle supporting function and the dispersive cable saddle diverging function, and the diverging section saddle groove is matched with the corresponding anchoring end, so that diverging and steering of cable strands of the main cable by the diverging section saddle groove are enabled to correspond to position of the anchor, steering angle of the cable strands is mild while supportive of large-angle adjustment and clear in stress, stability and reliability of a suspension bridge built by using the saddle can be ensured, extending length of the main cable can be reduced reasonably and effectively, compact control on bridge type of the suspension bridge is facilitated, and the multifunctional cable saddle is especially suitable for being fixed and used on side towers or bank foundations of the suspension bridge.

Description

technical field [0001] The invention relates to a core force-bearing part formed by a suspension bridge, in particular to a multifunctional cable saddle. Background technique [0002] Suspension bridges have been widely recognized and built a lot at home and abroad because of their light structure, beautiful appearance, grand momentum, large spanning capacity, and few environmental constraints on the bridge position. [0003] Both the dynamic load and the static load of the suspension bridge are borne by its main cable, while the support and direction control of the main cable are realized through the cable saddle, that is, the main cable and the cable saddle are the core force-bearing components of the suspension bridge. Cable saddles are divided into main cable saddles and scattered cable saddles according to their different positions in the construction of suspension bridges; The cable is supported and turned in the vertical direction (that is, up and down); the loose ca...

AI Technical Summary

Problems solved by technology

However, the overall saddle formed by the saddle of the supporting section and the saddle of the diverging section on the saddle body of this technology is formed in an arched structure, and the supporting section and the diverging section are sequentially connected on both sides of the highest point of the saddle, similar to the traditional main cable saddle Compared with the traditional main cable saddle, only one end of the saddle groove is an arc-shaped conical structure that flares outward; it can be seen that this technology limits the divergence angle of the main cable strands of the divergent section on the saddle body, The distribution and structure of the anchorage structure must match the divergence angle of the composite cable saddle, the length of the anchor span of the suspension bridge and the layout and structure of the anchorage structure are limited, which is not conducive to the control and realization of the light and beautiful structure of the suspension bridge.
