ABSTRACT:
A bracket assembly rests upon a pier set adjacent to a foundation and a secondary component elevates the bracket assembly. The bracket provides adjustable engagement to limit rotation of the bracket with respect to an installed pier. The bracket assembly has an housing, a bearing member, load transfer plates, reinforcing means, and an adjusting bolt beneath the bearing member. The housing is either two parallel plates or a tube. In the plates embodiment, two slots receive either a pin, a gate alone, or a gate with a moveable plate. In the tube embodiment, the pier fits snugly within the tube. Further, the bracket permits locating tools over the piers to reduce induced bending moment at the junction of the pier and the bracket. The bracket assembly stabilizes and lifts piers.
