Abstract
A precast concrete column supports a building. In one exemplary embodiment, the precast concrete column includes a connector for securing a wooden column to the precast concrete column such that no portion of the connector extends beyond the cross-section of the wooden column. In an alternative embodiment, a jack screw extends from the distal end of the precast concrete column to provide height adjustment for the precast concrete column. In certain embodiments, an insert or tube is cast into the precast concrete column body to allow a fastener to traverse the precast concrete column body so that structural components of the building may be secured thereto.
Claims25
A foundation column for providing support to a structure, the column comprising:
- a concrete column body having a proximal cross-sectional extent defining a cross-sectional envelope;
- an upstanding arm secured to and extending from a proximal end of said concrete column body, said upstanding arm having a cross-sectional extent along its length that never extends beyond the cross-sectional envelope defined by the proximal cross-sectional extent of the concrete column body;
- a wood column having a distal end, a proximal end and a perimeter along a wood column length between the distal end and the proximal end of the wood column, said wood column including a slot defined by an opening formed through the distal end of the wood column and extending toward the proximal end of the wood column, said slot terminating short of said perimeter, whereby access to said slot is permitted only through the distal end of the wood column, said slot sized to receive said upstanding arm extending from said proximal end of said concrete column body, whereby, with said upstanding arm received in said slot, a fastener may be positioned to engage said wood column and said upstanding arm to secure said wood column to said concrete column body;
- and
- an embedded anchor receiver embedded in said proximal end of the concrete column body, said embedded anchor receiver presenting an exposed face from said concrete column body.

A foundation column for providing support to a structure, the column comprising:
- a precast concrete column body having a proximal end and a distal end, the distal end defining an opening providing access to an internal threaded bore extending from said opening in said distal end toward said proximal end;
- a base comprising a polygonal plate having an exposed side;
- and
- a threaded extension extending from said base and threadedly engaging said internal threaded bore in said precast concrete column body, whereby, with said base engaging a floor of an earthen hole and said threaded extension threadedly engaged in said internal threaded bore of said precast concrete column body, said exposed side of said base resists rotation so that said precast concrete column is rotatable to adjust the height of the precast concrete column body relative to the floor of the earthen hole, wherein said precast concrete column body includes a proximal end and a distal end, the proximal end of the precast concrete column body having an embedded anchor receiver embedded therein, said embedded anchor receiver presenting an exposed face facing outwardly from said precast concrete column body.

A foundation column for providing support to a structure, the column comprising:
- a precast concrete column body having a proximal end and a distal end, the distal end defining an opening providing access to an internal threaded bore extending from said opening in said distal end toward said proximal end;
- a base comprising a polygonal plate having an exposed side;
- and
- a threaded extension extending from said base and threadedly engaging said internal threaded bore in said precast concrete column body, whereby, with said base engaging a floor of an earthen hole and said threaded extension threadedly engaged in said internal threaded bore of said precast concrete column body, said exposed side of said base resists rotation so that said precast concrete column is rotatable to adjust the height of the precast concrete column body relative to the floor of the earthen hole, wherein said precast concrete column body includes a proximal end and a distal end, the proximal end of the precast concrete column body having a transverse anchor receiver extending transversely therethrough.
1 more element
A method of anchoring a structure in the earth, comprising:
- forming an earthen hole having a floor;
- positioning a foundation column in the earthen hole, the foundation column comprising:
- a precast concrete column body having a proximal end and a distal end, the distal end defining an opening, a tube defining an internal threaded bore aligned with said opening in said distal end of said precast concrete column body;
- a base comprising a polygonal plate having an exposed side;
- a threaded extension extending from said base and threadedly engaging said internal threaded bore in said precast concrete body;
- and
- a transverse anchor receiver extending transversely through the proximal and of said precast concrete column body;
- said step of positing the foundation column in the earthen hole comprises the step of engaging the base with the floor of the earthen hole;
- and
- rotating said precast concrete column body relative to the floor of the earthen hole after said step of engaging the base with the floor of the earthen hole to adjust the height of the precast concrete column body relative to the floor of the earthen hole.
