Stay Cable System

Structural technologies is the exclusive designer and manufacturer of vsl post tensioning and construction systems in the united states.

Stay cable system.

The ssi 2000 c is a compact stay cable range with significantly reduced stay pipe diameters applying the same corrosion protection system as the standard ssi 2000. Stay cable systems dyna grip stay cable system. Vsl systems have a well earned reputation for their quality reliability and durability. The freyssinet hd stay cable can be adapted to provide better anti corrosion performance in aggressive environments by replacing the freyssinet monostrand with the cohestrand system.

Freyssinet h1000 stay cable is a parallel strand system for use in light structures applications include stay cables and angers for footbridges arch bridges suspended roofs and other cable structures. H1000 stay cable system. The h1000 range includes five cable for 1 4 7 12 and 19 strands. A ring nut is threaded onto the anchor block to transmit the cable force into the structure via the bearing plate.

First cable stayed bridges in the 60 s and 70 s of the last century new systems were introduced into the market considering new materials and increasing requirements on modern infrastructures the application of dsi s stay cable system for the odawara blueway bridge japan in 1994 which is known as the first extradosed. The system provides for a multilayer corrosion protection which guarantees a long service life. A leader in stay cable technology vsl brings you the experience of over. A cradle system carries the strands within the stays from the bridge deck to bridge deck as a continuous element eliminating anchorages in the pylons.

This particular invention has opened up the way to new applications in cable staying notably with the use of deviation saddles and the installation of turnkey. Stay cable system ssi 2000 stay cable system. Dyna grip stay cable systems if strands need to be guided through the pylon structure and a transfer of forces by friction is required dywidag offers a saddle in which the strands are guided from one side of the pylon to the other. Each epoxy coated steel strand is carried inside the cradle in a one inch 2 54 cm steel tube.

Where even lower wind drag is required the ssi 2000 d offers the most compact strand cable section in the market by eliminating the sheathing of the strands and providing equivalent.
