Abstract
Abstract Steel piers are fixed to concrete footings supported by the ground. These piers extend upward from the footings to support the girders of the frame of a house. The piers are adjustable in height so that they may be set to support the girders at proper distance above the ground. Each pier includes a top plate which is nailed to the supported girder. Each pier may be easily adjusted, if necessary, to compensate for subsequent heaving of the ground by readjusting the height of the pier. Selective locking of the adjusting mechanism against accidental retraction by vibration is provided without impeding extensibility under heaving stress.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
209 words
Apparatus for supporting a generally horizontally disposed girder above the ground, said girder having at least two juxtaposed substantially flat surfaces thereon, the apparatus comprising: a concrete footing supported by the ground and positioned below the girder; an upright post having a base contacting the concrete footing and a body extending upwardly from the base to the girder, said post body comprising a tubular member extending upwardly from the base, a shaft loosely slidable within the tubular member and extendable and retractable relative thereto, adjustment means operatively engaging said shaft and said tubular member for adjustably limiting the retraction of the shaft relative to the tubular member and a top plate fixed to the top of said shaft for engaging said girder, said adjustment means being adjustable to limit the retraction of the shaft when said plate engages said girder; said plate including a substantially flat planar portion directly engaging one of the flat surfaces of said girder and only one flange extending directly upwardly from said planar portion and substantially normal thereto directly engaging the other flat surface of said girder; means associated with said flange for fixing said flange to the other flat surface of said girder; and means for fixing the base to the concrete footing.
Claim 2
Dependent Claim
209 words
Apparatus for supporting a generally horizontally disposed girder above the ground, said girder having at least two juxtaposed substantially flat surfaces thereon, the apparatus comprising: a concrete footing supported by the ground and positioned below the girder; an upright post having a base contacting the concrete footing and a body extending upwardly from the base to the girder, said post body comprising a tubular member extending upwardly from the base, a shaft loosely slidable within the tubular member and extendable and retractable relative thereto, adjustment means operatively engaging said shaft and said tubular member for adjustably limiting the retraction of the shaft relative to the tubular member and a top plate fixed to the top of said shaft for engaging said girder, said adjustment means being adjustable to limit the retraction of the shaft when said plate engages said girder; said plate including a substantially flat planar portion directly engaging one of the flat surfaces of said girder and only one flange extending directly upwardly from said planar portion and substantially normal thereto directly engaging the other flat surface of said girder; means associated with said flange for fixing said flange to the other flat surface of said girder; and means for fixing the base to the concrete footing.
Claim 3
Dependent Claim
30 words
Apparatus according to claim 1 wherein the means for fixing the base to the concrete footing comprise a plurality of nails extending through the base and into the concrete footing.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 1 wherein the means for fixing the upwardly extending flange to the girder comprise a plurality of nails extending through the upwardly extending flange and into the girder.
Claim 5
Dependent Claim
105 words
Apparatus according to claim 3 wherein the girder comprises a pair of aligned girder portions abutting end to end, the flat portion and upwardly extending flange of the top plate seating against flat surfaces of each girder portion, wherein at least one of the plurality of nails extending through the upwardly extending flange extends into each girder portion, and whereiN are further included additional means for fixing the top plate to the girder comprising a plurality of nails extending through the flat portion and into the girder, at least one of the plurality of nails extending through the bottom portion extending into each girder portion.
Claim 6
Dependent Claim
76 words
Apparatus according to claim 4 wherein the shaft is threaded along its length, and wherein the adjustment means comprise a nut threadably engaged with the shaft, the nut contacting and bearing on the top of the tubular member to limit retraction of the shaft, and a clip which fits about the shaft immediately above the nut to limit the upward movement of the nut along the shaft under the force of the tubular member bearing thereon.
Claim 7
Independent Claim
251 words
A system for supporting a frame having a plurality of generally horizontally disposed girders above the ground, each of said girders having at least two juxtaposed substantially flat surfaces thereon, the system comprising: a plurality of concrete footings supported by the ground, each footing being positioned below a girder; a plurality of upright posts, each post having a base in contact with a concrete footing, a body extending upwardly from the base to the girder, each of said bodies comprising a tublar member extending upwardly from the base, a shaft loosely slidable within the tubular member and extendable and retractable relative thereto and adjustment means operatively engaging each of said shafts and said tubular members for adjustably limiting the retraction of the shafts relative to the tubular members and a top plate fixed to the top of each of said shafts for engaging said girders, each of said adjustment means being adjustable to limit the retraction of the shafts when said plates engage said girders; each of said plates including a substantially flat planar portion directly engaging one of the flat surfaces of each of said girders and only one flange extending directly upwardly from said planar portion and substantially normal thereto directly engaging the other flat surface of each of said girders; means associated with each of said flanges for fixing each of said flanges to the other flat surface of each of said girders; and means for fixing the bases of each of said posts to a concrete footing.
Claim 8
Independent Claim
251 words
A system for supporting a frame having a plurality of generally horizontally disposed girders above the ground, each of said girders having at least two juxtaposed substantially flat surfaces thereon, the system comprising: a plurality of concrete footings supported by the ground, each footing being positioned below a girder; a plurality of upright posts, each post having a base in contact with a concrete footing, a body extending upwardly from the base to the girder, each of said bodies comprising a tublar member extending upwardly from the base, a shaft loosely slidable within the tubular member and extendable and retractable relative thereto and adjustment means operatively engaging each of said shafts and said tubular members for adjustably limiting the retraction of the shafts relative to the tubular members and a top plate fixed to the top of each of said shafts for engaging said girders, each of said adjustment means being adjustable to limit the retraction of the shafts when said plates engage said girders; each of said plates including a substantially flat planar portion directly engaging one of the flat surfaces of each of said girders and only one flange extending directly upwardly from said planar portion and substantially normal thereto directly engaging the other flat surface of each of said girders; means associated with each of said flanges for fixing each of said flanges to the other flat surface of each of said girders; and means for fixing the bases of each of said posts to a concrete footing.
Claim 9
Dependent Claim
37 words
A system according to claim 6 wherein the means for fixing the base of each post to a concrete footing comprise a plurality of nails extending through the base of each post and into each concrete footing.
Claim 10
Dependent Claim
41 words
A system according to claim 6 wherein the means for fixing the upwardly extending flange of each top plate to a girder comprise a plurality of nails extending through the upwardly extending flange of each top plate and into a girder.
