Multifunctional epoxy coating prestressed tendon production line

Abstract

The invention relates to a multifunctional epoxy coating prestressed tendon production line. The production line comprises a pay-off machine, a traction machine I, a cleaning tank set, an intermediate frequency heating furnace, a wire separating disc, an electrostatic spraying tank, a device A (namely a heat preservation tank or a semi-finished product cooling tank), a central wire tensioning mechanism, a cooling tank, a traction machine II, a rewinding-winding machine, a heat preservation tank, a semi-finished product cooling tank, a driving motor and a long transmission shaft, wherein the long transmission shaft is connected with the driving motor and is also connected with the wire separating disc and the central wire tensioning mechanism, respectively. The multifunctional epoxy coating prestressed tendon production line can be used for producing three prestressed tendon products including an epoxy coating filling type steel strand, a monofilament coating type epoxy steel strand and an epoxy coating steel wire, and the surfaces of the steel strand and the prestressed steel wire can be thoroughly cleaned; meanwhile, by virtue of the central wire tensioning mechanism, the problem that a production line cannot work for a long time because a central wire is lengthened is solved.

Description

technical field [0001] The invention relates to a prestressed tendon production line, in particular to a multifunctional epoxy-coated prestressed tendon production line capable of producing three kinds of prestressed tendon products. Background technique [0002] Steel strands and steel wires are indispensable prestressed materials for various construction projects. In various port terminals, sea-crossing bridges, airports, and highways, there will inevitably be some gaps or gaps in reinforced concrete. When corroded by salt water or rainwater, the prestressed material in the component will cause corrosion, and the volume of iron oxide produced by the corrosion will expand dozens of times, resulting in cracking of the concrete, peeling off of the protective layer of the prestressed material, and direct exposure of the prestressed material to In the atmosphere, water and corrosive media, the corrosion of prestressed materials often directly leads to the premature destruction ...

AI Technical Summary

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a multifunctional epoxy resin that can produce three types of prestressed tendon products: epoxy-coated filled steel strand, monofilament-coated epoxy steel strand, and epoxy-coated steel wire. Coated prestressed tendon production line, the pretreatment of the production line cleans the surface of steel strands and prestressed steel wires more thoroughly, and also solves the problem that the production line cannot work for a long time due to the length of the central wire
