Description
Strand Anchorage
This invention relates to an anchorage for anchoring a tension member comprising one or more strands made up of elongate elements which may be wires of metallic material or rods of non-metallic or composite material.
A relatively recent innovation in the design of cable stays for stayed structures is the utilisation of cable stays which are composed of bundles of seven-wire prestressing strands. These seven-wire strands are traditionally used for prestressing concrete and other applications where high strength tension members are required. Each strand consists of six cold-drawn high carbon steel wires twisted around a slightly larger straight centre wire (kin wire). Heat treatment can confer good creep-resistance on the product. A more compact variant of the product "Dyform" (Trade Mark) strand (Patent GB 1 012 310), is made by drawing 2 seven-wire strand through a die under controlled conditions of tension and temperature.This prestressing strand is typically 15.2 mm in diameter but is available in a range of sizes. It can be produced cheaply through advanced production techniques and has high tensile strength (typically 1820 MPa), thus resulting in significant weight and cost savings.
Several anchorage systems have been developed for this type of cable stay. The salient feature of these systems is an anchor plate against which the individual strands are locked with external wedge grips. The grips take up considerable space and result in an anchorage which is bulky in relation to the number of strands in the cable. Moreover, the wedge grips have internal serrated profiles which cause indentation leading to premature failure under fatigue loading.
What is desired is a technique of anchoring prestressing strand bundles which obviates the aforementioned limitations of existing anchorage systems, in particular guaranteeing high integrity under both static (dead) and dynamic (live) loads.
The present invention provides an anchorage anchoring a tension member comprising a strand having an outer layer of elongate elements arranged around a central axis, the anchorage comprising an anchor member having a through-hole which receives a rear end portion of the strand, the through-hole having a forwardly tapering circumferential surface and the outer layer of elongate elements being splayed out rearwardly in the through-hole so as to lie along its tapering surface, wedging means being arranged between the said elongate elements in the said end portion of the strand so as to maintain them in their splayed position when the strand is under tension.
Preferred and optional features are set forth in claims 2 et seq.
The invention will be described further, by way of example, with reference to the accompanying drawings, in which:

Figure 8 is a diagrammatic cross-sectional view of an anchor plate for use in the anchorage of Figure 5.
The invention will be explained by reference to an anchorage designed for a single seven-wire strand 1. Although the invention concerns primarily steel strands, it is applicable to other metallic strands and to composite strands in which the wires or rods are circular or non-circular profiles reinforced with high strength fibres in a resin matrix.
Referring to Figure 1, the anchorage consists of a short splayed length L2 of strand 1, wedged in an anchor plate 5. The rear end portion of the strand is splayed by driving a wedging device 7, comprising six conical dowels 10, between the king wire 8 and the six outer wires 9 (Figs. 2a,b). When the strand 1 is loaded, the splayed end is wedged into a tapered hole 4 in the anchor plate 5. A typical dowel shape is shown in Figure 3. The geometry of the dowels 10 and tapered hole 4 are chosen to ensure that, during loading, initial contact takes place at the rear edge portion 11 of the hole 4 (Fig. 2b) to assist locking of the dowels 10. To prevent indentation of the strand, the rear edge portion 11 is relieved with a round fillet as shown at L in
Figure 2b. The front edge may also be rounded.
Alternatively, the splaying can be effected with a wedging device 7 comprising one or more grooved collets (Figure 4) instead of six individual dowels. The collet 12 has arcuate grooves 15 accommodating the respective outer wires 9, with tapering ridges defined between the grooves, and a central bore 14 accommodating the king wire 8. Longitudinal slits 13 allow limited compression of the collet 12 as it is driven into the hole 4.
A socket 2 is filled with a resin compound 3 to the level of the anchor plate 5 so that a length L1 (four or five times L2) of
2 the strand 1 (Figure 1) is potted. The potting compound 3 may be of the polyester, polyurethane or epoxy type. It is advantageous after the potting compound has cured, to introduce an epoxy resin 6 of thin consistency to improve the bond between the dowels 11 or collet(s) 12 and the strand 1, to fill up any voids between the resin cone formed by the potting compound 3 and the anchor plate 5 and any space not occupied by the splayed strand end in the tapered hole 4.
On loading the strand 1, two mutually interactive gripping mechanism are operative in the anchorage.
1) gripping of the short splayed length L2 of strand in the anchor plate 5. This provides most of the initial grip.
2) a wedging action of the resin cone 3 on the unsplayed length L1 of strand. This wedging action is augmented by virtue of the pressure applied by the anchor plate 5, which is in close contact with the cone. The small clearance between the anchor plate 5 and the socket bore permits the anchor plate 5 to maintain this intimate contact.
The conjoint action of the two gripping mechanism described above is a salient feature of the anchorage. Gripping mechanism (2) plays an important role in the satisfactory performance of the anchorage when the strand-anchorage assembly is subjected to live (fatigue) load.
Figure 5 and 6 show an anchorage for a prestressing strand bundle 16 comprising, in this particular instance, nineteen seven-wire strands 1 of the type shown in Figures 1 and 2a. The anchorage comprises, by way of example an externally screw-threaded socket 17 in which the structural load is transmitted through an adjustable nut 18 having a bearing surface 19, although any other design of socket could be used incorporating a truncated conical cavity 21. A sectional view of the bundle 16 (Figure 7) shows that the nineteen strands 1 are assembled substantially in close-packed hexagonal arrangement, which gives the most compact assembly in terms of steel area. In the truncated conical cavity 21 of the socket 17, the individual strands 1 are fanned (brushed) out to engage tapered holes 4 in the anchor plate 20. The tapered holes 4 are arranged (Figure 6) to preserve, in the fan, the hexagonal format of the bundle 16.
With the exception of the central tapered hole for the centre strand, the outer eighteen (six plus twelve) tapered holes are inclined to match the respective inclination of the strands in the fan. Referring to Figure 8, the axes of the tapered holes for the layer of six and twelve strands are, respectively, inclined at an angle 81 and 02 (82 > 81) Thus continuity of the fan is maintained in the anchor plate. Also, because bulky wedge grips are not used to secure the strand in the anchor plate, the tapered holes in the anchor plate can be densely packed, thus resulting in a compact arrangement.
The ends of the nineteen strands 1 are splayed by inserting wedging devices 7, which are either conical dowels or grooved collets, as described in the anchorage for a single strand. The conical cavity 21 below the anchor plate 20 is filled with a thermosetting resin compound 3. Epoxy resin 6 is introduced to provide intimate contact between the anchor plate 23 and the resin cone formed by the compound 3 and further insurance of wedging action in the anchor plate. The wedging action in the anchor plate 20 is sufficient to break the bundle statically.
However, the additional wedging action generated in the resin cone 3 ensures an anchorage which resists fatigue damage under dynamic loading.
This anchorage is applicable to prestressing strand bundles comprising any suitable number of strands (e.g. 7, 19, 37, 61, 91, 127). It can equally be extended to cover composite seven-rod prestressing strands in which the rods are circular profiles reinforced with high strength fibres in a resin matrix.
The resin matrix can be of the thermosetting or thermoplastic type.
