Abstract
This invention relates to a system and method for supporting a building and to a system and method for connecting sections, such as pilings, pipes, conduits, and the like, in an end-to-end, abutting, relationship to form pilings for the support system.
Claims46
A system for raising and supporting the foundation or slab of a building, the system comprising a lifting arm assembly for engaging the lower surface of the foundation or slab, the lifting arm assembly comprising a support sleeve, a piling section extending through the support sleeve, means for applying a load to the piling section to drive a portion of the piling section into the ground;
- and a connection assembly for connecting the piling section to an additional piling section in response to the portion of the piling section being driven into the ground, the connection assembly comprising a first connecting member secured in one of the piling sections, a second connecting member secured in the other piling section, and a third connecting member connecting the first and second connecting members, and therefore the piling sections in an abutting, end-to-end relationship wherein each of the piling sections are internally threaded and wherein the first and second connecting members have external threads that threadedly engage the internal threads of the corresponding piling sections to secure the first and second connecting members to their corresponding piling sections.
A method for raising and supporting the foundation or slab of a building, the system comprising engaging the lower surface of the foundation or slab with a lifting arm including a support sleeve, inserting a piling section into the support sleeve, applying a load to the piling section to drive the piling section into the ground, threadedly engaging a first connecting member with the piling section, threadedly engaging a second connecting member with another piling section, and connecting the first and second connecting members with a third connecting member to connect the piling sections in an abutting, end-to-end relationship.
A system for connecting two elongated, internally threaded, tubular sections in an abutting end-to-end relationship, the system comprising a first externally threaded connecting member in one of the tubular sections in threaded engagement therewith, a second externally threaded connecting member in the other tubular section in threaded engagement wherewith, and a third connecting member connecting the first and second connecting members, and therefore the tubular sections in an abutting, end-to-end relationship.
A method for connecting two elongated tubular sections in an abutting end-to-end relationship, comprising providing internal threads on the tubular sections, providing external threads on an exterior surface of a first and a second connecting member, threadedly engaging the first connecting member in one of the tubular sections, threadedly engaging the second connecting member in the other tubular section, and connecting the first and second connecting members with a third connecting member to connect the tubular sections in an abutting, end-to-end relationship.
A building foundation installation comprising:
- a first piling having a helix section formed at one end thereof for penetrating the ground;
- the other end portion of the piling being internally threaded;
- an externally threaded connecting member in threaded engagement with the internally threaded other end portion of the piling;
- a second piling for supporting a load and having an internally threaded end portion;
- an externally threaded connecting member in threaded engagement with the internally threaded end portion of the second piling;
- and
- a third connecting member connecting the first and second connecting members, and therefore the pilings, in an abutting, end-to-end relationship.
A system for raising and supporting the foundation or slab of a building, the system comprising:
- a lifting assembly comprising:
- means for engaging the foundation or slab;
- and
- a support sleeve connected to the engaging means;
- and
- a piling assembly extending through the support sleeve and comprising:
- a first piling section,
- a helix secured to the first piling section and adapted to penetrate the ground,
- a first internally threaded connecting member secured in the first piling section,
- a second piling section,
- a second internally threaded connecting member secured in the second piling section, and
- a third externally threaded connecting member connecting the first and second connecting members, and therefore the piling sections, in an abutting, end-to-end relationship;
- and
- a driving mechanism for driving the piling assembly, including the helix section, into the ground until a predetermined resistance is encountered.
