Abstract
A lift bracket system for lifting a building structure such as a foundation and the like comprising a lift plate having a top surface and a bottom surface, the top surface for insertion under the building structure; a generally cylindrical housing affixed to the lift plate and extending perpendicularly from the top surface and the bottom surface of the lift plate, the housing defining a generally circular opening through the lift plate, the opening being disposed away from the center of the lift plate; and at least one gusset for supporting the lift plate, the gusset having a first end and a second end, the gusset disposed beneath the lift plate, wherein the first end of the gusset is attached to the bottom surface of the lift plate and the second end of the gusset is attached to the housing.
Claims9
A support system for a building structure such as a foundation comprising:
- a pier disposed in the ground below the building structure to be supported, the pier comprising a support pile extending up toward the building structure;
- at least one extension pier piece, the extension piece having a first end and a second end, the first end having a first pair of holes oriented normal to the surface of said extension piece, and a second pair of holes oriented normal to the surface of said extension piece, said first pair of holes being spaced apart longitudinally and orthogonally offset from said second set of holes and the second end having fixedly attached thereto a coupling, the coupling having two pairs of holes therethrough and being sized to receive a second pipe with generally mating holes, wherein the coupling is operably connected to the support pile;
- and a lift bracket operably connected to the extension piece.
An improved support system for lifting a building structure comprising a foundation pier having an extension piece and a lift bracket system engaged with the foundation pier, wherein the improvement comprises:
- a shaft having a first end and a second end, wherein said shaft is composed of metal and is prefilled with a non-metallic substance, leaving unfilled portions near the pair of holes to permit fasteners to be inserted therethrough;
- a coupler attached to the first end of the shaft and having at least one pair of holes for receiving a fastener;
- and
- the second end of the shaft having at least one pair of holes for receiving a fastener.
