Main cable saddle of suspension bridge

Abstract

The invention provides a main cable saddle of a suspension bridge, which belongs to the technical field of bridges. The main cable saddle comprises a bottom plate, a saddle body and a locking assembly; a sliding groove is formed in a first plate surface of the bottom plate, a plurality of mounting grooves are formed in a second plate surface of the bottom plate, a plurality of pre-buried mountingholes and a plurality of grouting holes are formed in each mounting groove, pre-buried rods are inserted into the pre-buried mounting holes, and the bottoms of the pre-buried rods are used for being inserted into the tower top of the suspension bridge; the saddle body is movably installed in the sliding groove. The locking assembly comprises a plurality of locking bases, the locking bases are symmetrically arranged on the two opposite sides of the saddle body in the moving direction of the saddle body respectively, the side face, facing the saddle body, of each locking base and the saddle bodyare detachably installed together, and the bottom face, facing the bottom plate, of each locking base and the first plate face of the bottom plate are detachably installed together. The bottom plateis arranged to replace existing structures such as an upper bearing plate, a lower bearing plate and a grid reaction frame, the number of parts of the main cable saddle is greatly reduced, the manufacturing cost is reduced, and the manufacturing period is shortened.

Description

technical field [0001] The disclosure belongs to the technical field of bridges, in particular to a main cable saddle of a suspension bridge. Background technique [0002] Long-span bridges mostly adopt the structural form of suspension bridges. Suspension bridges generally include main cable saddles and scattered cable saddles. The main cable saddle is an important component of the main cable support in the suspension bridge. The main cable saddle is used to place the main cable and is generally located on the top of the main tower. superior. [0003] In the related technology, the main cable saddle includes a saddle body and a base, wherein the base generally includes components such as a lower bearing plate, an upper bearing plate, a mounting plate, a tie rod, a stopper, a grid and a reaction frame, embedded steel bars, and embedded brackets. . The saddle body and the upper bearing plate are assembled together through positioning pins, the bottom of the upper bearing pl...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned main cable saddle structure, the base includes many parts, and the external dimensions of the parts are large, and the structure of each part is complicated, so that the main cable saddle has a long manufacturing cycle, high manufacturing cost, and cumbersome installation.
