Combined-type cable holder with replaceable main cables

Abstract

A combined-type cable holder with replaceable main cables comprises 2n side cable holder bodies and a middle cable holder body. Each side cable holder body is a separated cable holder body which is provided with a groove, wherein connection steps at two sides of each side cable holder body are respectively provided with m circular holes for installation of high-strength bolts. Two sides of the middle cable holder body are respectively provided with n grooves. Two sides of each groove of the middle cable holder body are respectively provided with m threaded holes or circular holes for installation of the high-strength bolts. The lower portion of the middle cable holder body is a lug plate connected with a sling, wherein pin holes used for connection of the lug plate and the sling are formed in the lug plate. When the combined-type cable holder is used, the 2n side cable holder bodies are respectively connected with the middle cable holder body with the 2n grooves through high-strength bolt pairs to constitute the combined-type cable holder, a single main cable is separated into 2n small main cables distributed side by side for clamping, after a suspension bridge is built, the side cable holder bodies can be detached one by one, maintenance and replacement for the small main cables can be carried out, m is larger than or equal to 2 and smaller than or equal to 100, and n is larger than or equal to 2 and smaller than or equal to 50.

Description

technical field [0001] The invention relates to a main cable accessory suitable for a suspension bridge, in particular to a combined cable clamp that can replace the main cable. Background technique [0002] As the bridge with the largest span, the suspension bridge has developed rapidly in China, and the main cable as the lifeline of the suspension bridge has always been the main subject of research by engineers and technicians from all over the world; especially the research on the anti-corrosion of the main cable is particularly important; because if the cable system is corroded, The consequences are unimaginable; in order to ensure the safety of the bridge and the safety of the cable structure, the cables must be protected against corrosion. In view of the limitations of our understanding and the research on the main cable corrosion of the suspension bridge has not yet achieved satisfactory results, there are currently many Few bridge cables still rely on cable replaceme...

Problems solved by technology

[0002] As the bridge with the largest span, the suspension bridge has developed rapidly in my country, and the main cable as the lifeline of the suspension bridge has always been the main subject of research by engineers and technicians from all over the world; especially the research on the anti-corrosion of the main cable is particularly important; because if the cable system is corroded, The consequences are unimaginable; in order to ensure the safety of the bridge and the safety of the cable structure, the cables must be protected against corrosion. In view of the limitations of our understanding and the research on the main cable corrosion of the suspension bridge has not yet achieved satisfactory results, there are currently many Few bridge cables still rely on cable replacement to solve the problems of anti-corrosion and safety performance of bridge cables; in the structural system of suspension bridges, our company has developed a replaceable anchorage system and has successfully applied it in Wuhan Yangluo Yangtze River Bridge, etc.; therefore, to solve the problem of changing the main cable of the suspension bridge, it is necessary to have a cable clamp and a cable structure that can change the main cable; and the existing cable clamps such as Figure 18-19 As shown, it includes the upper cable clamp body 5 and the lower cable clamp body 6 with grooves, and the upper cable clamp body 5 and the lower cable clamp body 6 are connected by high-strength bolt pairs to form a large main cable 8 for clamping, so It is almost impossible to change the cable body

[0003] The applicant applied for a "replaceable cable clamp for the main cable" last year, but its structure is single, and the width of the transverse bridge is relatively large, which cannot meet the needs of various types of suspension bridges.
