Abstract
The invention relates to an entire filling plastic coating steel strand that includes a core thread and plural side track. The feature is that it is coated a HDPE plastic anticorrosion insulation, and HDPE plastic anticorrosion layer is also filled in the clearance between core thread and side track. It has good anticorrosion capability, and has the same mechanical properties and utilization property as normal PC steel strand.
Description
Technical field:
The present invention relates to the member that a kind of prestress engineering is used, particularly do not have the integral-filled type plastic-coated steel twisted line that bonding worker method is used.Be widely used in and do not have bonding worker method construction anchor cable.
Background technology:
At present, as the steel strand of one of prestress engineering main member, particularly there are not the steel strand that bonding worker method is used, for improving its Corrosion Protection, general employing has the plain bar twisted wire of HDPE protective jacket, or sprays one deck or double layer of metal in the appearance of plain bar twisted wire, referring to Fig. 1, Fig. 2.Perhaps at the appearance spray epoxy of each root steel wire of plain bar twisted wire, referring to Fig. 3.Perhaps the patent No. as the applicant application is the patent shown in 03259753.3: spray epoxy in the appearance of plain bar twisted wire and gap thereof, and referring to Fig. 4.First three plants structure, has the gap between each steel wire of steel strand, and corrosive mediums such as water and air can enter these gaps from the end, thereby causes the steel strand can not be fully anticorrosion.The 4th kind of structure, the antiseptic property brilliance, but its cost is higher.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, providing a kind of neither influences the original mechanical performance of steel strand, and the lower integral-filled type plastic-coated steel twisted line of cost.
The object of the present invention is achieved like this: a kind of integral-filled type plastic-coated steel twisted line, comprise the steel strand that a heart yearn and Duo Gen side line constitute, it is characterized in that: around the outer rim of these steel strand, apply a HDPE plastics anticorrosive coat, and in the gap of heart yearn and each side line, also fill full the 2nd HDPE plastics anticorrosive coat.
Integral-filled type plastic-coated steel twisted line of the present invention at the steel strand surface coating grease that applies a HDPE plastics anticorrosive coat or the mixture of paraffin or grease and paraffin, applies the 3rd HDPE plastics anticorrosive coat again outside it.
Because adopt said structure, the present invention's integral-filled type plastic-coated steel twisted line has the following advantages:
1, has superior corrosion resistance, chemical resistance and water resistance;
2, solve common anticorrosive steel strand aqueous vapor and enter the problem that antiseptic power is reduced by the gap between each steel wire of forming steel strand;
3, mechanical performance is consistent with common PC steel strand.

The specific embodiment
Embodiment 1: integral-filled type plastic-coated steel twisted line
As shown in Figure 5, heart yearn 1 and Duo Gen side line 2 constitute steel strand, apply a HDPE plastics anticorrosive coat 3 around the outer rim of these steel strand, and this coating layer thickness is 0.8mm-1.2mm.And in the gap of heart yearn 1 and each side line 2, also fill full the 2nd HDPE plastics anticorrosive coat 4.
Embodiment 2: in fill out the integral-filled type plastic-coated steel twisted line of grease or paraffin
This kind strand structure is the mixture 5 that applies grease or paraffin or grease and paraffin at the steel strand surface of embodiment 1 described coating the one HDPE plastics anticorrosive coat 3 as shown in Figure 6, applies the 3rd HDPE plastics anticorrosive coat 6 again outside it.Grease and paraffin can be any mixing ratio.
Claims (3)
1. integral-filled type plastic-coated steel twisted line, comprise the steel strand that a heart yearn (1) and many side lines (2) constitute, it is characterized in that: around the outer rim of these steel strand, apply a HDPE plastics anticorrosive coat (3), and in the gap of heart yearn (1) and each side line (2), also fill full the 2nd HDPE plastics anticorrosive coat (4).
2. a kind of integral-filled type plastic-coated steel twisted line according to claim 1, it is characterized in that:, outside it, apply the 3rd HDPE plastics anticorrosive coat (6) again at the steel strand surface coating grease that applies a HDPE plastics anticorrosive coat (3) or the mixture (5) of paraffin or grease and paraffin.
3. a kind of integral-filled type plastic-coated steel twisted line according to claim 1 and 2 is characterized in that: HDPE plastics anticorrosive coat (a 3) thickness of described steel strand is 0.8mm-1.2mm.
