Flange-to-Flange Connection of Precast Concrete Members

摘要

Flange-to-flange connectors and construction methods using such connectors are disclosed. The connector may include a first and second anchored plates secured to a first and second sets of anchoring bars. The connector may also include a first and second alignment plates configured to mate with the first and second anchored plates. The connector may further include at least one shim configured to be positioned between the first and second anchored plates. A bolt may be configured to secure the first and second alignment plates with the first and second anchored plates, respectively, and when the bolt is tightened, the bolt pulls the first and second alignment plates and the first and second anchored plates together to form a rigid connection, which may eliminate the need to form and cure concrete at job sites, allowing the time, cost, and construction complexity to be reduced significantly compared to conventional connection systems.
