Abstract

A modular cable clamp for a suspension bridge comprises an upper half cable clamp, a lower half cable clamp, a connecting plate and a double-thread screw. The upper half cable clamp and the lower half cable clamp are both of a semi-arc-shaped plate structure, the two sides of the upper half cable clamp and the two sides of the lower half cable clamp are fixedly connected through a plurality of double-thread screws, the bottom of the lower half cable clamp is fixedly connected with the top of the connecting plate, the connecting plate is of a flat plate structure, and a pin hole is formed in the bottom of the connecting plate. According to the design, the number of casting models can be reduced, the production cost of the cable clamp is effectively reduced, the casting difficulty of the cable clamp can be effectively reduced, the production cost of the cable clamp is reduced, and the production period is shortened.

Description

technical field [0001] The invention relates to a cable clamp for a suspension bridge, in particular to a modular cable clamp for a suspension bridge, and is particularly suitable for a pin-connected cable clamp for connecting a main cable and a suspension cable. Background technique [0002] At present, most long-span bridges adopt the structural form of suspension bridges. Suspension bridges refer to bridges with suspension cables as the main load-bearing structure. The main structures are: main cables, cable towers, anchorages, suspension cables, stiffening beams and bridge decks. The cable clamp is an important connection between the main cable of the suspension bridge and the suspension cable of the bridge deck. The cable clamp is a key stress-bearing part connecting the bridge deck and the main cable, and requires a reliable and stable connection. The current cable clamp includes an upper half cable clamp and a lower half cable clamp. The upper half cable clamp and th...
