ABSTRACT:
An adjustable support bracket to be used in combination with a support pier or post to support a structure subject to weights or loads. A support pier is placed in proximity to a surface requiring support. At the end of the support pier, in proximity to the surface requiring support, a generally rigid flat surface is placed. On that flat surface are a plurality of support bolts generally perpendicular to the flat surface. The bolts are threaded and are provided with locking nuts. A matching second flat surface is placed above the first flat surface and between the first flat surface and the structure requiring support. A plurality of sleeves are on the second flat surface. The sleeves are sized and shaped for receipt of the support bolts on the first flat surface. The sleeves are slipped over the bolts on the first flat surface, leaving a space between the first and second flat surfaces. A jack or other lifting device is placed in this space and is used to push the second flat surface into contact with the structure requiring support. Once an appropriate level of support is achieved, locking nuts on the threaded support bolts are rotated into place against the sleeves on the second flat surface to provide support to the second flat surface for any weight placed on the second flat surface because of its proximity to the structure requiring support. The jack may then be removed and the support pier with the support bracket now bears the load generated by the structure requiring support.
