Method for manufacturing waterproof cable holder

Abstract

The invention relates to a suspension bridge beam, in particular to a cable holder for a suspension bridge. In a method for manufacturing a waterproof cable holder, a left semi-cable holder and a right semi-cable holder and a high-strength bolt for clamping a cable strand are used, and the cable strand comprises a steel wire and a polyethylene sheath outside the steel wire; and the method for manufacturing the waterproof cable holder comprises the following steps of: 1, stripping certain length of polyethylene (PE) from the cable strand, uniformly coating one layer of wet putty on the surface of the naked steel wire, and filling the gap in the steel wire; 2, coating multiple passes of sealant on the inner side contacted with each semi-cable holder, and arranging the cable holders; 3, arranging seal rings at the two ends of the cable holders, coating sealant on the ports of an outlets, coating a layer of sealant on the periphery of the gap generated by closing the two cable holders, and sealing the whole cable holder comprising a bolt hole and a hole inner wall; and 4, fastening two semi-cable holders by using the high-strength bolt. Rainwater or moisture can be effectively prevented from entering the cable holder so as to protect the steel wire in the cable holder from being rusted, and prolong the service life of an inhaul cable.

Description

technical field [0001] The invention relates to a suspension bridge, in particular to a cable clamp for a suspension bridge. Background technique [0002] With the rapid development of our country's national economy, highway bridges and construction industries are being deployed on a large scale across the country as the infrastructure of municipal construction. In some small bridges and building structures, the interconnection between steel wire cables is completed by cable clips. As an integral part of the superstructure of the bridge, the cable clamp assembly is very important to the whole bridge. The weight of the bridge body and the load on the bridge surface are transferred to the main cable of the bridge by the sling clamps, and at the same time, all the clamps hold the main cable as a whole to enhance the ability of the main cable to withstand tension. However, due to the certain angle between the suspension cable and the suspension cable, the cable clamp must provi...

Problems solved by technology

However, due to the certain angle between the suspension cable and the suspension cable, the cable clamp must provide sufficient clamping force to resist the sliding component force caused by the suspension cable along the tangential direction of the suspension cable, which requires that the suspension cable must be stripped. The PE sheath makes the cable clamped on the surface of the steel wire, but this process causes the surface of the steel wire to be exposed to the air. Under the influence of rain and moisture, the steel wire will be corroded for a long time and the service life of the cable will be reduced.
