Abstract
The utility model relates to a renewable steel strand used as a prestressed member for constructional engineering such as roads, bridges and the like. The renewable steel strand comprises a steel strand body (1). The renewable steel strand is characterized in that an HDPE (High-Density Polyethylene) tube (3) with the thickness t is arranged outside the steel strand body (1); a lubricant (2) is filled between the steel strand body (1) and the HDPE tube (3); and the value of the thickness t of the HDPE tube (3) ranges from 2mm to 5mm. The renewable steel strand has a renewable function and a multilayer corrosion resistance effect, so that the anticorrosion resistance of the steel strand is improved.
Description
Technical field
The utility model relates to the prestressed member that the construction works such as a kind of road, bridge are used, and particularly relates to a kind of steel strand that can substitute function that have.
Background technology
As the steel strand of one of prestress engineering main member, at present the steel strand that several classes have anti-corrosion function have appearred, as zinc-plated or zinc/aluminum-plated steel twisted wire, epoxy coating strand and plastic-coated steel twisted line, and the steel strand that extrude again PE outside aforementioned steel strand.Steel strand are extremely crucial prestressed members, though aforementioned a few class anticorrosive steel strand possesses certain antiseptic property, but at applying working condition under abominable or important application occasion, for guaranteeing safety, when having arrived certain service life, need to carry out the withdrawing steel strand of taking a sample to check to steel strand and whether damage or change, but the structure of aforementioned a few class steel strand is substituted structure and function without this.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of steel strand that can substitute function and have the multiple-anticorrosion function that have are provided.
The purpose of this utility model is achieved in that a kind of shaped steel twisted wire of substituting, comprise the steel strand body, it is characterized in that: this externally is manufactured with the HDPE pipe that thickness is t at described steel strand, and fill lubricator between described steel strand body and HDPE pipe, the span of described HDPE tube thickness t is 2 mm≤t≤5mm.
Described steel strand body can be plain bar twisted wire body, zinc-plated or zinc/aluminum-plated steel twisted wire body, epoxy coating strand body or plastic-coated steel twisted line body.
The utility model can be substituted the shaped steel twisted wire, and described steel strand body also can be the steel strand body of above-mentioned steel strand outsides bag PE sheath, and described lubricator is filled between PE sheath and HDPE pipe.
The lubricator of described filling can adopt anti-corrosion grease or wax.
Owing to adopting technique scheme, the utility model compared with prior art has the following advantages:
1, increase the protection number of plies, thereby strengthened antiseptic property;
2, during use, can go out steel strand by withdrawing from high density polyethylene pipe, be convenient to check whether the steel strand of drag-line inside damage;
3, can realize not removing high density polyethylene pipe and the purpose of substituting steel strand.
Description of drawings
Fig. 1 is that the utility model can be substituted shaped steel twisted wire embodiment 1 cross-sectional structure schematic diagram.
Fig. 2 is that the utility model can be substituted shaped steel twisted wire embodiment 2 cross-sectional structure schematic diagrames.

The specific embodiment
Embodiment 1:
Referring to Fig. 1, Fig. 1 is that the utility model can be substituted shaped steel twisted wire embodiment 1 cross-sectional structure schematic diagram.As seen from Figure 1, the utility model can be substituted the shaped steel twisted wire, comprise steel strand body 1, being manufactured with thickness outside described steel strand body 1 is the HDPE(high density polyethylene (HDPE) of t) pipe 3, and fill lubricator 2 between described steel strand body 1 and HDPE pipe 3, the span of described HDPE pipe 3 thickness t is 2 mm≤t≤5mm.Steel strand body 1 can slide in HDPE manages 3 when pull.
Described steel strand body can be plain bar twisted wire body, zinc-plated or zinc/aluminum-plated steel twisted wire body, epoxy coating strand body or plastic-coated steel twisted line body.Also can be the steel strand body of above-mentioned steel strand body outsourcing PE sheath 4.
The lubricator of described filling can adopt anti-corrosion grease or wax.
Embodiment 2: referring to Fig. 2, Fig. 2 is that the utility model can be substituted shaped steel twisted wire embodiment 2 cross-sectional structure schematic diagrames.As seen from Figure 2, embodiment 2 is with the difference of embodiment 1, extrudes the steel strand body of PE sheath 4 outside steel strand body 1 has adopted.Described lubricator 2 is filled between described PE sheath 4 and HDPE pipe 3.Steel strand body with PE sheath 4 can slide in HDPE manages 3.
Claims (5)
1. can substitute the shaped steel twisted wire for one kind, comprise steel strand body (1), it is characterized in that: being manufactured with thickness outside described steel strand body (1) is the HDPE pipe (3) of t, and fill lubricator (2) between described steel strand body (1) and HDPE pipe (3), the span of described HDPE pipe (3) thickness t is 2 mm≤t≤5mm.
2. a kind of shaped steel twisted wire of substituting according to claim 1, is characterized in that: the lubricator of described filling (2) employing anti-corrosion grease or wax.
3. a kind of shaped steel twisted wire of substituting according to claim 1 and 2 is characterized in that: the outer PE sheath (4) that extrudes of described steel strand body (1), described lubricator (2) is filled in PE sheath (4) and manages between (3) with HDPE.
4. a kind of shaped steel twisted wire of substituting according to claim 1 and 2 is characterized in that: described steel strand body (1) is plain bar twisted wire body, zinc-plated or zinc/aluminum-plated steel twisted wire body, epoxy coating strand body or plastic-coated steel twisted line body.
5. a kind of shaped steel twisted wire of substituting according to claim 4 is characterized in that: described steel strand body (1) is the steel strand body at plain bar twisted wire body, zinc-plated or zinc/aluminum-plated steel twisted wire body, epoxy coating strand body or plastic-coated steel twisted line body outsourcing PE sheath (4).
