Problems solved by technology

Second, stainless steel cables and bars are easily stretched (either elastically or permanently)
Third, it often happens that stainless steel cables and rods are not tensioned along a perfectly straight path, but must bend at some points
In addition, in the state where the tensile member is partially bent, the strength will be reduced

Embodiment Construction

[0044] Figure 1 shows an exploded view of a terminal fitting end 10 comprising a terminal fitting body 12, deflection means or expansion means such as a conical insert 14 and means 16 for securing the conical insert, such as a closed annular nut 16, The closed ring nut 16 has an external thread 18 and an internally threaded bore 20 . The threaded earhook portion 22 of the tensioner portion is sized and threaded to threadably engage the internal threads 20 of the closed ring nut. The conical insert 14 is preferably made of a strong rigid material such as stainless steel, aluminum, titanium and other high strength materials. The terminal fitting body 12 has a proximal end 24 through which an axial bore 26 passes. The intermediate portion 28 of the terminal fitting has a flared lumen 30 that flares outwardly from its proximal end 32 to its distal end 34 to form a truncated conical cavity. The terminal housing has a distal end 36 with connection means 38 , such as a female threa...

Abstract

A composite tension member. The composite tension member is assembled from a number of composite rods, each having two ends. A wedge plug is formed around the ends of the composite rods. The wedge plugs are inserted into termination fitting having a termination fitting body with an aperture at a proximal end for receipt of the bundle of composite rods and having an internal cavity that flares outwardly from a proximal end to a distal end to closely receive the wedge plug with the composite rods imbedded therein. A closeout nut is used to retain the wedge plug in the termination fitting body. The invention further provides method of manufacturing composite tension members.

Description

technical field [0001] The present invention relates to a composite tensile member and a method of making such a member, in particular to a composite tensile member comprising a plurality of parallel composite fiber strips which are wrapped in a central composite rope section Bundled, the strips are either cone flared to form a terminal joint and secured to the joint with adhesive and friction, or the strips are embedded in a wedge or truncated cone plug, the wedge A piece or cone plugs into a fitting that fits into the terminal. Background technique [0002] There are many aspects that require high-strength and light-weight tensile components, such as static cable components for sailboats, guy wires for industrial components, lifting ropes, mooring cables for offshore drilling platforms, and prestressed tendons for bridges, etc., just to name a few. some. [0003] In areas where handling is sensitive, such as competitive sailing, low-weight, low-section tensile components...
