Prestressed concrete sectioned structure stress members coupling - involves anchoring wires in existing anchor plate with wedges already built in

摘要

The device is used esp. in sectional erection of prestressed concrete structures, such as bridges. the coupling device consists of a force-locked connection between two stress members by wedge-anchoring wires in a common anchor plate. Wires (6) from the member being anchored are anchored in the anchor plate (1) of the stressed member at the coupling joint, by wedges (2) already built in. Wedges may be held by spring elements (4) which press them against the wires This is easily effective, but reliable under repetitive dynamic stress.
