Abstract
Abstract Method of producing a rod anchoring structure particularly for use in high tension insulators. It comprises an assembly of a rod in an anchoring fixing. The end of the rod is fitted with a surrounding double ended wedge element having a neck and flaring in both directions along the rod away from the neck. This wedge element is then jammed in the anchoring fixing, either by deforming a sleeve tightly around the wedge element or by winding a filament tightly around it.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
78 words
A method of producing a rod anchoring structure comprising the steps: molding onto the end of a rod a surrounding, double-ended wedge element having a neck from which flared ends of increasing cross-sectional area extend in both axial directions along the rod, and concentrically mounting to said wedge element an anchoring fitting with said anchoring fitting radially compressing said wedge element over said neck and said flared ends in the absence of an axial load on the rod.
Claim 2
Independent Claim
78 words
A method of producing a rod anchoring structure comprising the steps: molding onto the end of a rod a surrounding, double-ended wedge element having a neck from which flared ends of increasing cross-sectional area extend in both axial directions along the rod, and concentrically mounting to said wedge element an anchoring fitting with said anchoring fitting radially compressing said wedge element over said neck and said flared ends in the absence of an axial load on the rod.
Claim 3
Dependent Claim
54 words
A method according to claim 1, wherein said anchoring fitting has an initial shape of an open-ended tubular sleeve in which the wedge element-bearing of tht rod is received and said step of concentrically mounted said anchoring fitting to said wedge element comprises deforming said open-ended nozzle-shaped sleeve press tight against the wedge element.
Claim 4
Dependent Claim
29 words
A method according to claim 2, wherein said sleeve is formed of thin ductile metal and said deforming step comprises isostatic pressing of said sleeve onto said wedge element.
Claim 5
Dependent Claim
32 words
A method according to claim 2, wherein said sleeve is formed of thin ductile metal and said step of deforming said sleeve comprises magnetic crimping of said sleeve onto said wedge element.
Claim 6
Dependent Claim
38 words
A method according to claim 2, wherein said sleeve is formed of a high mechanical strength metal and said step of deforming said sleeve comprises cold working of said sleeve to press said sleeve onto said wedge element.
Claim 7
Dependent Claim
33 words
A method according to claim 2, wherein said sleeve is formed of a high mechanical strength metal and said step of deforming said tubular sleeve comprises forging said sleeve onto said wedge element.
Claim 8
Dependent Claim
25 words
A method according to claim 5, wherein the wedge element is covered with a layer of soft metal before having the sleeve pressed onto it.
Claim 9
Dependent Claim
31 words
A method according to claim 2, further comprising the step of strapping said sleeve at least in the vicinity of the neck after fitting of said sleeve to said wedge element.
Claim 10
Dependent Claim
44 words
A method according to claim 8, wherein said sleeve is made of metal and said step of strapping said sleeve in the vicinity of the neck comprises moulding an exterior sleeve of a metal of lower melting point than said sleeve to said sleve.
Claim 11
Dependent Claim
22 words
A method according to claim 8, wherein said step of strapping of said sleeve comprises winding a metal wire around said sleeve.
Claim 12
Dependent Claim
20 words
A method according to claim 1, wherein the anchoring fitting is formed by winding a filament around the wedge element.
Claim 13
Dependent Claim
13 words
A method according to claim 11, wherein the filament is a metal wire.
Claim 14
Dependent Claim
14 words
A method according to claim 11, wherein the filament is a resin-impregnated organic fibre.
Claim 15
Dependent Claim
47 words
A method according to claim 2, wherein said step of deforming said tubular sleeve into an open-shaped nozzle-shaped sleeve against the wedge element comprises initially deforming said fitting about the neck of the wedge element and subsequently deforming the remainder of said fitting against said flared ends.
Claim 16
Dependent Claim
27 words
A method according to claim 14, wherein said deformation of said fitting onto said wedge element is progressively away from said neck and towards either side thereof.
Claim 17
Dependent Claim
43 words
A method according to claim 2, further comprising the step of applying an axial force to the rod during deforming of said tubular sleeve to provide a degree of axial pre-tensioning between the two halves of the wedge element and the anchoring fitting.
Claim 18
Dependent Claim
65 words
A method according to claim 16, wherein the anchoring fitting is initially fitted tightly to the half of the wedge element which is nearest to the end of the rod, the rod is then subject to traction away from the fitted end and the other anchoring fitting is tightened around the other half of the wedge element while the rod is subject to the traction.
Claim 19
Dependent Claim
48 words
A method according to claim 2, wherein said rod is made of resin-agglomerated fibres, said wedge element is moulded of resin, and said step of moulding of said wedge element comprises the moulding of said wedge element of resin before the resin of the rod has completely polymerized.
