Abstract
Abstract This invention relates to a free-standing upwardly-convergent pouring form for poured concrete wall structures that includes a pair of upstanding form panels held in fixed spaced relation both top and bottom by a plurality of transverse tie members and an anchor member suspended from said form panels above the ground in position to receive wet concrete poured therebetween. The invention also contemplates the improved method of anchoring a free-standing upwardly-convergent concrete pouring form to the ground which comprises pouring a portion of the wet concrete onto the top of an anchor member suspended above ground level between the form panels so that the concrete resting atop said anchor member will overbalance the hydrostatic forces tending to lift the forms as they are filled.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
The free-standing form for poured concrete wall structures which comprises: a pair of upstanding panels cooperating with the support therefor to define an open-topped cavity adapted to receive and retain wet concrete, at least one of said panels having an inwardly-extending overhanging portion; upper and lower rows of transverse tie members arranged in longitudinally-spaced relation interconnecting the panels and adapted to maintain a fixed spaced relation therebetween, said lower row of tie members being spaced above the supporting surface upon which the panels rest; and, means defining an anchor member suspended from the panels into the cavity therebetween in position to receive a portion of the wet concrete poured into the open top thereof, said anchor member including a horizontally-disposed upwardly-facing surface of substantial width defining a supporting area adapted to carry a sufficient weight of concrete which when added to the weight of the pouring form assembly thus formed will counterbalance any lifting forces generated when said wet concrete presses upwardly against said overhanging portion.
Claim 2
Dependent Claim
166 words
The free-standing form for poured concrete wall structures which comprises: a pair of upstanding panels cooperating with the support therefor to define an open-topped cavity adapted to receive and retain wet concrete, at least one of said panels having an inwardly-extending overhanging portion; upper and lower rows of transverse tie members arranged in longitudinally-spaced relation interconnecting the panels and adapted to maintain a fixed spaced relation therebetween, said lower row of tie members being spaced above the supporting surface upon which the panels rest; and, means defining an anchor member suspended from the panels into the cavity therebetween in position to receive a portion of the wet concrete poured into the open top thereof, said anchor member including a horizontally-disposed upwardly-facing surface of substantial width defining a supporting area adapted to carry a sufficient weight of concrete which when added to the weight of the pouring form assembly thus formed will counterbalance any lifting forces generated when said wet concrete presses upwardly against said overhanging portion.
Claim 3
Dependent Claim
37 words
The free-standing concrete pouring form as set forth in claim 1 in which: the lower row of tie members provide the support for the anchor member that suspends the latter within the cavity between the form panels.
Claim 4
Dependent Claim
39 words
The free-standing concrete pouring form as set forth in claim 1 in which: the anchor member comprises an elongate relatively rigid sheet of a width substantially less than the horizontal distance separating the adjacent form wall surfaces alongside thereof.
Claim 5
Dependent Claim
34 words
The free-standing concrete pouring form as set forth in claim 3 in which: the anchor member is of a length greater than the longitudinal distance separating adjacent tie members in the bottom row thereof.
Claim 6
Dependent Claim
19 words
The free-standing concrete pouring form as set forth in claim 3 in which: the anchor member is transversely corrugated.
Claim 7
Dependent Claim
25 words
The free-standing concrete pouring form as set forth in claim 4 in which: the anchor member is of a length approximating that of the panels.
