[0002] Threaded steel bars for prestressed concrete are also called fine-rolled threaded steel bars. The steel bars can be connected by connectors with internal threads or anchored by nuts with threads at any cross-section. In the cast-in-place construction of bridge cantilevers, the hanging basket needs to be anchored to the cast beam section. Steel strands are generally designed in the web of the cantilever as vertical prestressed tendons, and the hanging basket needs to use fine-rolled threaded steel as an anchoring member.
