[0004] 1. The strength of the steel wire is low. At present, two grades of steel wire, 1770Mpa and 1670Mpa, are basically used. Compared with the 1860Mpa and 1960Mpa steel strand, the strength is lower. , thus increasing the weight of the cable body
[0005] 2. The anchorage structure with steel wire as the main material is relatively large, which not only makes the design of the bridge itself more difficult, but also causes disadvantages such as high design and manufacturing costs.
[0006] 3. Steel cables cannot meet the design requirements under high stress amplitude state
[0007] 4. The cable body of the cold cast anchor and the hot cast anchor is a parallel steel wire bundle. The steel wire and the anchor cup are heated and solidified by epoxy iron sand t...

Abstract
The invention discloses a composite strand tapered anchoring steel strand finished product cable, which comprises a cable body and two anchoring ends positioned on two ends of the cable body, wherein each anchoring end comprises an anchoring and clamping section and a sealing antiseptic section; each anchoring and clamping section comprises an end cover, a clamping piece, a wire splitting anchor plate, an anchor cup, an extension cylinder and a restriction ring; each wire splitting anchor plate is a cone with an external taper; the inner cavity of each anchor cup and the inner hole of each extension cylinder are both inner taper holes; each single steel strand of the steel strand finished product cable body is clamped on the wire splitting anchor plate by the camping piece; each wire splitting anchor plate is positioned in the inner taper hole of each anchor cup to be tightly cooperated with the inner taper hole of each anchor cup so as to form a positioning wedge-shaped anchoring structure; each extension cylinder is filled with epoxy iron sand to form a taper-shaped body which performs an auxiliary anchoring function on the steel strand finished product cable; and each sealing antiseptic section comprises a sealing cylinder, an O-shaped sealing ring and a gland. The finished cable has the advantages of high stress fatigue resistance, good shock resistance, reliable anchoring performance, compact anchorage structure and convenience in manufacture installation and anchorage change construction and is suitable for the bridge inhaul cable under the high-fatigue stress state.
Description
technical field [0001] The invention relates to a cable used in bridge construction and large-scale construction projects, especially a clip-type composite anchoring steel strand that can be used in cable-stayed cables, arch bridge suspenders, suspension bridges and cable net structures for special occasions. Finished cable and its manufacturing method. Background technique [0002] Since the reform and opening up, my country's architecture and bridge construction have developed rapidly, and many new bridges have continued to rise. Various arch bridge suspenders and suspension bridge suspenders have been widely designed and used on bridges, and the structural forms of suspenders are constantly being updated. . [0003] In recent years, the types of cables used in domestic bridges and large buildings mainly include: cold cast anchor wire cables, hot cast anchor wire cables, clip anchor steel strand cables and steel strand whole bundle extruded finished cables search. Among ...
