The cable anchorage is achieved using standard button type wedge anchors used in the prestressed concrete industry. The cables used are ½”φ ASTM A416 Grade 270 seven wire, low relaxation, strand. This type of cable is commonly used in prestressed and post tensioned concrete construction.

FAQs - The Industry That Makes Supply Chains Work

Research has shown that a wedge anchor may be placed 3.0 bolt diameters (center-to-center) away from an empty hole without reducing the pullout-capacity of the anchor. If the empty hole is filled with dry-pack mortar a wedge anchor may be installed within 1.5 bolt diameters (center-to-center) of the hole.

US8925279B2 - Anchoring, splicing and tensioning …

Anchoring devices and systems are disclosed for use with elongated reinforcement members such as FRP, SRP, metallic bars, or cables. Such devices and systems impart a compressive stress into a static structure having the elongated reinforcement member running there through or there along. An anchoring system can include an anchor block that includes a front end surface for contacting the ...
