Abstract
The utility model relates to a dull polish type epoxy coating filled steel strand which is characterized in that the outer surface of a steel strand with a smooth surface twisted by a plurality of steel wires (1) is coated with epoxy material (2); gaps among the steel wires are all fully filled with epoxy material (3); one layer of grit (4) is evenly inserted on the surface of the epoxy material (2) on the outer layer. The utility model has the advantages of good anti fatigue performance, corrosion prevention and good service stability and holding performance with concrete or water mixing slurry.
Description
Technical field:
The utility model relates to a kind of steel strand wires, specifically relates to a kind of frosted type epoxy coating filling section steel twisted wire.Be mainly used in the prestressed structure.
Background technology:
Before the utility model was made, general steel strand wires were to use steel wire many light faces or plating zinc on surface or coating epoxy resin twisted together.This steel strand wires are mainly used in the prestressed structure, owing to have certain clearance between each steel wire of these steel strand wires, and zinc layer and epoxy coating are too thin, therefore also have some defectives:
1. anti-fatigue performance is relatively poor: the steel wire of general steel strand wires very easily produces CONTACT WITH FRICTION with peripheral concrete or other metal.
2. Corrosion Protection is poor: therefore general plain bar twisted wire is very easy to be corroded by steam or corrosive deposit owing to do not protect; Galvanized strand wires is because the zinc layer is too thin, and because the steel wire of galvanized strand wires contacts with peripheral concrete or other metal friction, the zinc layer very easily comes off, so do not have long-term corrosion-resistant effect; General epoxy steel strand wires (using the many steel wire epoxy steel strand wires twisted together that apply epoxy resin), because epoxy coating is extremely thin, and epoxy coating discontinuous (pin holes that the surface is very many), can not continue to bring into play corrosion proof function.
3. stability in use is poor: the mutual changing of the relative positions can take place in the steel wire of general steel strand wires, influences the stability of using, and easily produces the fine motion fatigue under scrubbing between the steel wire.
With concrete or cement mortar bond (bonding) poor performance: general steel strand wires are used for the prestressing with bond structure, and are therefore very little with the frictional resistance of concrete or cement mortar because steel strand surface is smooth, very easily pull out from concrete.
The existence of above defective makes general steel strand wires can not satisfy the requirement of detail design.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of have remarkable anti-fatigue performance and antiseptic property, good stability in use and reliably and the frosted type epoxy coating filling section steel twisted wire that bonds (bonding) performance of concrete or cement mortar are provided.
The object of the present invention is achieved like this: a kind of frosted type epoxy coating filling section steel twisted wire, be by the many plain bar twisted wire surface-coated epoxy materials that steel wire is twisted together, every gaps between steel wires all has the epoxy material complete filling, and one deck sand grains in the uniform embedding of outer epoxy material surface.
Compare with existing steel strand wires, the utlity model has following advantage:
1. anti-fatigue performance brilliance: because frosted type epoxy coating filling section steel twisted wire skin applies with epoxy material, epoxy material has certain thickness, can prevent effectively that the steel wire of steel strand wires and peripheral concrete, cement mortar or other metal from producing CONTACT WITH FRICTION.
2. corrosion resistance brilliance: owing to yet all coated and filled by epoxy material between frosted type epoxy coating filled-type steel strand surface and the steel wire, can prevent that steam and corrosive medium from infiltrating, the protection steel strand wires are not corroded.
3. stability in use is good: owing to also filled by epoxy material between the frosted type epoxy coating filling section steel twisted wire steel wire, effectively prevented the sliding friction between the twisted wire steel wire, improved whole service life.
With concrete or cement mortar to bond (bonding) performance good: because one deck sand grains in the uniform embedding of the outer epoxy material surface of frosted type epoxy coating filling section steel twisted wire, increased the frictional resistance with concrete or cement mortar, can guarantee that frosted type epoxy coating filling section steel twisted wire and concrete or cement mortar bond together reliably.
Description of drawings:
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is a kind of frosted type epoxy coating filling section steel twisted wire.Be characterized in: the steel strand wires outer surface that is twisted into by many steel wires 1 applies epoxy material 2, and every gaps between steel wires all has epoxy material 3 complete filling, and one deck sand grains 4 in the uniform embedding of outer epoxy material surface.
Specific operation process of the present utility model is: earlier steel wire 1 is twisted into steel strand wires; Then steel strand wires are carried out the epoxy spraying, make steel strand surface and every gaps between steel wires all fill full epoxy material 2 and 3; Adhere to one deck sand grains 4 uniformly on outer epoxy material surface at last.
