Abstract
Prestressing force plastic -coated steel strand wires, including core wire, a plurality of periphery steel wire and outer plastic -coated layer, core wire crowded package outward has a rubber layer, and the periphery steel wire closely strands in rubber layer periphery, and with rubber layer extrusion form concave to core wire interior concave part and the convex outer convex part of core wire orientation deviates from, interior concave part tightly supports in periphery steel wire periphery, in the space that outer convex part stretched into two tangent periphery steel wires and enclose on the rubber layer. This prestressing force plastic -coated steel strand wires strands the in -process, and under periphery steel wire and core wire's combined action, the rubber layer takes place the deformation and to effectively packing in between the periphery steel wire and the clearance between periphery steel wire and the core wire, promotes the inside closely degree of steel strand wires, has guaranteed loaded homogeneity of follow -up prestressing force and slackness ability, strengthens and improved this prestressing force plastic -coated steel strand wires's prestressing force performance, the emergence of phenomenon such as infiltration can also be avoided simultaneously in the steel wire clearance, the probability that steel strand wires probably take place the corruption has further been reduced.
Description
Technical field
This utility model belongs to steel strand wires technical field, particularly to a kind of prestressing force plastic-coated steel twisted line.
Background technology
Prestress wire itself does not have antiseptic property, is easily corroded in use, thus to using this steel strand wires
Construction quality cause to have a strong impact on.In order to improve the antiseptic power of steel strand wires, technical staff have developed and various steel strand wires entered
The antiseptic methods of row, plastic-coated method is the more ripe method of one of which.But plastic-coated steel twisted line yet suffers from one
Fixed problem, such as steel strand wires internal structure defective tightness, uniformity and relaxation property that the follow-up prestressing force of impact loads, and
Affect the service life of steel strand wires eventually, and easily therefore lead to the phenomenon such as infiltration in steel wire gap in use, and then affect whole
Body antiseptic property.
Utility model content
In order to solve the above problems, this utility model aims to provide a kind of internal tightness well, can eliminate because of inside
Structure defective tightness and give the dysgenic prestressing force plastic-coated steel twisted line that steel strand wires service life and antiseptic property are brought.
The technical scheme of this prestressing force plastic-coated steel twisted line is realized in：
Described prestressing force plastic-coated steel twisted line, including core wire, stranded some peripheries steel wire in core wire periphery, applies
It is overlying on the outer coating layer outside mutually stranded some peripheries steel wire, outside core wire, be extruded with rubber layer, periphery steel wire closing lay
In rubber layer periphery, and rubber layer extruding formation is concaved towards the inner fovea part of core wire and deviates from the outer of core wire direction protrusion
Protuberance；
Inner fovea part is closely against periphery steel wire periphery, and male part stretches into what two tangent periphery steel wires and rubber layer were surrounded
In space.
Further, described core wire periphery is coated with internal plastic coating layer, is extruded with rubber layer outside internal plastic coating layer.
Further, described periphery steel wire periphery is all also coated with strengthening coating layer.
Further, described periphery steel wire diameter is less than core wire diameter.
Further, described internal plastic coating layer is made up of polytetrafluoroethylmaterial material.
Further, described outer coating layer is made up of polytetrafluoroethylmaterial material.
Further, described reinforcement coating layer is made up of polytetrafluoroethylmaterial material.
This prestressing force plastic-coated steel twisted line in order to solve because itself rigidity is former thus result in stranded when periphery steel wire between and
Cannot be in close contact between periphery steel wire and core wire, there is either large or small gap, extrude outside core wire
The good rubber layer of one layer of elastic performance, in stranding process, under the collective effect of periphery steel wire and core wire, rubber layer is sent out
Change shape, and the gap between the steel wire of periphery and between periphery steel wire and core wire is effectively filled, so that steel
Twisted wire internal tightness is greatly improved it is ensured that the uniformity of follow-up prestressing force loading and relaxation property, strengthens and improves
The prestressing force performance of this prestressing force plastic-coated steel twisted line；The lifting of steel strand wires internal tightness can also avoid steel wire gap simultaneously
The generation of the phenomenons such as interior infiltration, further reduces steel strand wires it may happen that the probability of corrosion, thus it is overall to be conducive to being lifted it
Antiseptic property.
