Abstract
The invention relates to a parallel un-bonded prestressed steel strand bundle with a ribbon sheath, which is characterized in that: n un-bonded steel strands (1) are arranged straightly, and then a plastic ribbon sheath (5) is manufactured outside the straightly arranged n un-bonded steel strands, wherein the n is more than or equal to 2 and less than or equal to 13. The parallel un-bonded prestressed steel strand bundle with the ribbon sheath can simplify the construction and improve the work efficiency and the construction quality, and has broader application occasions such as external cables, un-bonded internal cables, bridge inhaul cables and other large-span building structural inhaul cables compared with the prior art.
Description
(1) technical field
The present invention relates to the prestressing without bondn member that construction works such as a kind of road, bridge are used, can be widely used in rope, bridge cable and other long span building structure drag-line in external tendon, the no cohesive body.
(2) background technology
In the prestressing without bondn engineering, non-bending steel cable is the prestressed member of using always, its structure as shown in Figure 1, non-bending steel cable 1 can be plain bar twisted wire, zinc-plated or zinc-plated aluminum steel twisted wire, epoxy coating strand, steel strand outsourcing HDPE sheath 3, fill cosmoline fat 2 between non-bending steel cable 1 and the HDPE sheath, as Fig. 2.When the non-bending steel cable boundling uses, generally with the cloth or the band 4 of plastics or other material n root non-bending steel cable is manually wrapped up boundling at the construction field (site), the span commonly used of n is 2≤n≤19.Engineering discipline requires each root non-bending steel cable of boundling to want the keeping parallelism trend, and twisted wire reaches whole boundling each other and does not produce twisting, so when construction cloth muscle, must take a lot of supports, location measure in walking upwards of steel strand boundling, it is loaded down with trivial details to construct, difficulty is big, and the poor quality guarantees, particularly needs curve to move towards the occasion that requires in large-scale circular construction work and steel strand boundling cloth muscle.In addition, this prestress steel twist wire harness can not stackedly use.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of easy construction is provided, quality assurance can stackedly be used, and can be applicable to the parallel un-bonded prestressed steel strand bundle that banded sheath is arranged of multiple occasion.
For achieving the above object, technical scheme of the present invention is: a kind of parallel un-bonded prestressed steel strand bundle that banded sheath is arranged, it is characterized in that: n root non-bending steel cable is " one " word arrangement, make the banded cover of plastics again outside being the n root non-bending steel cable of " one " word arrangement, the span of described n is 2≤n≤13.
For making each root non-bending steel cable keeping parallelism further, do not produce twisting, can between each adjacent two non-bending steel cable, make the plastics link bar.
The banded cover of described plastics cross section can be rectangle, and its dual-side also can be arc.
Because adopt technique scheme, the present invention compared with prior art has the following advantages:
But 1 batch production is made, and builds Shaoshi worker site work amount, improves construction quality;
2, guarantee each root non-bending steel cable runs parallel, reduce the construction of support, location measure, can once connect up many, improve work efficiency;
3, have the parallel un-bonded prestressed steel strand bundle of banded sheath can be according to requirement of engineering, the stackable amalgamation of steel wire bundle be used;
4, has application scenario widely, as rope, bridge cable and other long span building structure drag-line in external tendon, the no cohesive body.

(5) specific embodiment
Embodiment 1:
Referring to Fig. 3, Fig. 3 has the cross-sectional structure schematic diagram of the parallel un-bonded prestressed steel strand bundle embodiment 1 of banded sheath for the present invention.As seen from Figure 3, the parallel un-bonded prestressed steel strand bundle that banded sheath is arranged, n root (n=4 in the present embodiment) non-bending steel cable 1 is " one " word arrangement, outside being the n root non-bending steel cable of " one " word arrangement, be manufactured with the banded cover 5 of the rectangular plastics of cross section again, thereby form a parallel un-bonded prestressed steel strand bundle that banded sheath is arranged.The span of described n is 2≤n≤13.
Embodiment 2:
As a kind of conversion of embodiment 1, the both sides of the banded cover 5 of described plastics are arc, make its cross section be oval shape, as Fig. 4.
Embodiment 3:
For making each root non-bending steel cable 1 keeping parallelism further, do not produce twisting, in the present embodiment, between each adjacent two non-bending steel cable, make plastics link bar 6, as Fig. 5.
Embodiment 4:
As a kind of conversion of embodiment 3, the both sides of the banded cover 5 of described plastics are arc, as Fig. 6.
Embodiment 5:
Can there be the stackable amalgamation of parallel un-bonded prestressed steel strand bundle of banded sheath to use, as Fig. 7 according to requirement of engineering.
Claims (4)
