Abstract
The utility model relates to a smooth epoxy coating filled steel strand rope, which comprises a smooth epoxy coating filled steel strand bundle (7) and HDPE sheaths (4, 5) which are coated on the surface of the smooth epoxy coating filled steel strand bundle (7). The utility model is characterized in that the smooth epoxy coating filled steel strand bundle (7) is composed of epoxy materials (2) which are coated on the outer surfaces of the steel strands and smooth epoxy coating filled steel strands, wherein steel strands are formed by twisting a plurality of steel wires (1), and epoxy materials (3) are filled in the gaps among steel wires; the outer surface of the smooth epoxy coating filled steel strand bundle (7) is coated with one layer or two layers of HDPE sheaths. The utility model has good corrosion resistant performance, and strand ropes are not easy to generate rusting corrosion.
Description
Technical field:
The utility model relates to a kind of construction cable-stayed bridge or part cable-stayed bridge or other Suo Cheng unique construction smooth type epoxy coating filling section steel twisted wire strand.
Background technology:
So far, zinc-coated wire strand and galvanized strand wires strand are the main bearing member of cable-stayed bridge and part cable-stayed bridge.Because it exposes in atmosphere, and corrosion failure easily takes place throughout the year.For addressing this problem, in recent years, people have designed the technical scheme of squeezing attached plastic sheath at the outer surface of good galvanized steel tow of twisting or galvanized strand wires bundle, and are used.It is to improving antiseptic effect, prolonging strand and played certain effect service life.But because in a single day the plastics anticorrosive coat destroys, corrosive medium will infiltrate corrosion galvanized steel tow and galvanized strand wires bundle.And easily produce changing of the relative positions friction during owing to galvanized steel tow or galvanized strand wires Shu Shouli between single zinc-coated wire or the single galvanized strand wires; the protection zinc layer of zinc-coated wire or galvanized strand wires is destroyed easily; therefore its antiseptic property is relatively poor; corrosion and destruction easily takes place in the strand cable body, has reduced strand service life.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of good airproof performance, strand to be difficult for taking place the smooth type epoxy coating filling section steel twisted wire strand of corrosion.
The purpose of this utility model is achieved in that a kind of smooth type epoxy coating filling section steel twisted wire finished product strand, the HDPE sheath that comprises smooth type epoxy coating filled-type steel wire bundle and be coated on smooth type epoxy coating filled-type steel wire bundle surface is characterized in: the steel strand wires outer surface that described smooth type epoxy coating filled-type steel wire bundle is twisted into by many steel wires applies epoxy material, every gaps between steel wires all is made up of the smooth type epoxy coating filling section steel twisted wire that epoxy material is filled; Outer surface at smooth type epoxy coating filled-type steel wire bundle coats one deck or two-layer HDPE sheath.Like this, when steel wire bundle is stressed between the single smooth type epoxy coating filling section steel twisted wire as changing of the relative positions friction takes place, the surperficial epoxy coating of smooth type epoxy coating filling section steel twisted wire therefore can be not destroyed owing to adopting proprietary formula yet, and opposite epoxy coating can be alleviated changing of the relative positions friction; Just in case the HDPE sheath destroys, corrosive medium infiltrates and also can not impact smooth type epoxy coating filling section steel twisted wire.Therefore, the utility model Corrosion Protection is very good, and service life is long especially.
Description of drawings:
Fig. 1 is a smooth type epoxy coating filling section steel twisted wire cross-sectional structure schematic diagram
Fig. 2 is a cross-sectional structure schematic diagram of the present utility model.
The specific embodiment:
As Fig. 1, smooth 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.
As Fig. 2, the utility model is by center smooth type epoxy coating filled-type steel wire bundle 7 and the high-strength polyester fibers band overcoat 6 that is coated on center smooth type epoxy coating filled-type steel wire bundle 7 outer surfaces, outermost layer is two-layer HDPE overcoat, internal layer 5 is a black, and outer 4 colors can be decided as requested.
Specific operation process of the present utility model is: earlier steel wire 1 is twisted into steel strand wires; Again 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; With many smooth type epoxy coating filling section steel twisted wires and become a branch of, twisting limit, limit is wrapped with high-strength polyester fibers band overcoat 6 then; Outer surface at smooth type epoxy coating filled-type steel wire bundle 7 coats one deck or two-layer HDPE sheath 4,5 at last.
Claims (1)
1, a kind of smooth type epoxy coating filling section steel twisted wire finished product strand, the HDPE sheath (4,5) that comprises smooth type epoxy coating filled-type steel wire bundle (7) and be coated on smooth type epoxy coating filled-type steel wire bundle (7) surface is characterized in that: the steel strand wires outer surface that described smooth type epoxy coating filled-type steel wire bundle (7) is twisted into by many steel wires (1) applies epoxy material (2), every gaps between steel wires all has the smooth type epoxy coating filling section steel twisted wire of epoxy material (3) filling to form; Outer surface at smooth type epoxy coating filled-type steel wire bundle (7) coats one deck or two-layer HDPE sheath (4,5).
