Foundation lifting assembly and method of use

Abstract

A lifting assembly for raising, supporting, and stabilizing a foundation or other weighted member. An anchoring bracket, which is mounted to a piling or pier that has been driven into the ground below the location where the foundation is to be poured, is attached to a jacking assembly. The jacking assembly includes a bottom plate which rests on the upper end of the vertical support column, a hydraulic jack which rests on the bottom plate, and a top plate which is supported by the hydraulic jack. Concrete which will form the foundation is poured into the foundation mold and around the anchoring bracket which rests in said mold. The concrete foundation is allowed to cure. Support rods which are secured to the anchoring bracket and bottom and top plates, transfers the upward force generated by the hydraulic lift, from said top plate to said anchoring bracket, thus lifting the foundation to which the anchoring bracket is integrally attached.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of and priority to a U.S. Provisional Patent Application No. ______ filed ______, the technical disclosure of which is hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates generally to an assembly and method for lifting supporting, and stabilizing structural building foundations and more particularly, to an assembly having an anchoring portion integrally attached to said foundation which is lifted, relative to a support column, by a jacking portion of said assembly such that said foundation is lifted off the ground.DESCRIPTION OF THE RELATED ART[0003]When the construction of a structure such as a house or other building is set to commence, particular attention must be paid to the stability of the ground upon which the structure will be built. The foundation of the structure must rest on stable, level ground in order to prevent damage to the foundation, and ver...

AI Technical Summary

Benefits of technology

[0007]Accordingly, there is provided herein, a lifting assembly (and method of use) that, in its preferred embodiments, is capable of raising, stabilizing, and supporting a structural foundation such that a portion of said assembly is integrally attached to said foundation.

[0009]In another aspect of the invention, each of a plurality of holes which have been formed on the upper support structure of the anchoring bracket, receive a threaded rod which is secured thereto by a nut on the underside of said upper support structure. A jacking assembly, comprising a bottom plate, top plate, and a hydraulic jack, is configured to lift the anchoring bracket. The bottom plate is removably mounted on the top end of the vertical support column, thus providing a stable support for the lifting means, which is positioned between the bottom plate and top plate. The support rods which are secured to the anchoring bracket, extend through holes formed in each of the top and bottom plates. Nuts are fastened to support rods on the upper part of each of the top and bottom plates.

Problems solved by technology

Fractures in a foundation can severely affect the structural integrity of the house or other building supported by said foundation, or at the very least, require the owner of such a structure to expend a substantial amount of money in order to remedy the problem.

A drawback of the assembly disclosed in the Rupiper patent is that while it is suitable for lifting a preexisting foundation, it is less suitable for use in construction of new structures as the pierhead is not integral to the foundation.
