Abstract
Abstract A permanently-installed form-drain (10) including hollow, foraminous planks (12) and connectors (16,18) for joining two or more of the planks in a continuously arranged concrete barrier. The instant improvements include an adapter (20/21), which serves as a straight connector, grooved plank (19) with interlocking stake (13/14), integral connector-stake and adapter-stake device (16/14, 20/14) and a tri-functional, generally rigid bracket and bracket-stake (22 and 22/22x) element, used to space and restrain/constrain the planks and/or to hold (support) reinforcement bars.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
170 words
A hollow multi-elemental, permanently installed concrete form-drain comprising in combination: a plurality of hollow, essentially rectilinear and elongate planks, said planks being foraminous on one side thereof, nonforaminous on the other side, essentially continuous at a bottom thereof and having interior symmetry about a horizontal central plane; at least one preformed hollow, non-plank connecting element for joining two or more said planks in an end-to-end configuration, said connecting element possessing a cross-sectional symmetry and means for fitting said element to an end of one of said preformed hollow planks, connection of multiple planks with multiple connecting elements resulting in a continuous form having an inner peripheral structure and an outer peripheral structure of containment of concrete between the structures, said connection providing continuous drainage through and about the structures; and means for rigidly securing two or more said planks in parallel spaced-apart relationship to form an integral concrete foundation form so that the foraminous side of said planks face such that they provide inside and outside foundation peripheral drainage means.
Claim 2
Dependent Claim
170 words
A hollow multi-elemental, permanently installed concrete form-drain comprising in combination: a plurality of hollow, essentially rectilinear and elongate planks, said planks being foraminous on one side thereof, nonforaminous on the other side, essentially continuous at a bottom thereof and having interior symmetry about a horizontal central plane; at least one preformed hollow, non-plank connecting element for joining two or more said planks in an end-to-end configuration, said connecting element possessing a cross-sectional symmetry and means for fitting said element to an end of one of said preformed hollow planks, connection of multiple planks with multiple connecting elements resulting in a continuous form having an inner peripheral structure and an outer peripheral structure of containment of concrete between the structures, said connection providing continuous drainage through and about the structures; and means for rigidly securing two or more said planks in parallel spaced-apart relationship to form an integral concrete foundation form so that the foraminous side of said planks face such that they provide inside and outside foundation peripheral drainage means.
Claim 3
Dependent Claim
13 words
The form-drain of claim 1, wherein said means for fitting includes an adapter.
Claim 4
Dependent Claim
23 words
The form-drain of claim 2, wherein the adapter further comprises flange means at an end thereof adapted to slide into a plank end.
Claim 5
Dependent Claim
20 words
The form-drain of claim 3, wherein the adapter further comprises a collar means transversely disposed peripherally and approximately midway thereabout.
Claim 6
Dependent Claim
13 words
The form-drain of claim 4, wherein the collar means further includes a stake.
Claim 7
Dependent Claim
13 words
The form-drain of claim 1, wherein the connecting element includes an integral stake.
Claim 8
Dependent Claim
35 words
The form-drain of claim 1 further comprising an "L" shaped stake, and planks and/or connecting elements having a continuous longitudinal groove, at least on the top thereof, for accepting thereinto a portion of the stake.
Claim 9
Dependent Claim
20 words
The form-drain of claim 7, further characterized by a ledge means disposed between a head and tip of the stake.
Claim 10
Dependent Claim
199 words
A hollow multi-elemental, permanently installed concrete form-drain comprising in combination: a plurality of preformed hollow, essentially rectilinear and elongate planks, said planks being foraminous on one side thereof, nonforaminous on the other side, essentially continuous at a bottom thereof and having interior symmetry about a horizontal central plane; and at least one preformed hollow, non-plank connecting element for joining two or more planks in an end-to-end configuration, said connecting element possessing a cross-sectional symmetry for fitting said element to a plank end so that connection of multiple planks with multiple connecting elements results in a continuous form having an inner peripheral structure and an outer peripheral structure for containment of concrete between the structure while, concomitantly, said connection provides continuous drainage through and about the structures; and a bracket means having a castellated shape wherein said bracket means includes lateral portions possessing a hollow rectilinear shape to partially circumscribe and enclose a portion of a plank and to hold two said planks in essentially spaced-apart, parallel relationship on an earthen surface, a cross bar of said castellated shape being disposed relative to said lateral portions at a desired height above the surface to orient and support reinforcement bars thereon.
Claim 11
Dependent Claim
199 words
A hollow multi-elemental, permanently installed concrete form-drain comprising in combination: a plurality of preformed hollow, essentially rectilinear and elongate planks, said planks being foraminous on one side thereof, nonforaminous on the other side, essentially continuous at a bottom thereof and having interior symmetry about a horizontal central plane; and at least one preformed hollow, non-plank connecting element for joining two or more planks in an end-to-end configuration, said connecting element possessing a cross-sectional symmetry for fitting said element to a plank end so that connection of multiple planks with multiple connecting elements results in a continuous form having an inner peripheral structure and an outer peripheral structure for containment of concrete between the structure while, concomitantly, said connection provides continuous drainage through and about the structures; and a bracket means having a castellated shape wherein said bracket means includes lateral portions possessing a hollow rectilinear shape to partially circumscribe and enclose a portion of a plank and to hold two said planks in essentially spaced-apart, parallel relationship on an earthen surface, a cross bar of said castellated shape being disposed relative to said lateral portions at a desired height above the surface to orient and support reinforcement bars thereon.
Claim 12
Dependent Claim
21 words
The form drain of claim 9, wherein the bracket includes at least one outside lateral portion extended to effect a stake.
Claim 13
Dependent Claim
85 words
Means for securing two planks of a concrete form in rigid, spaced-apart relationship comprising a bracket with a castellated shape the two lateral portions thereof each possessing a continuous rectilinear geometric shape which partially circumscribes and encloses a portion of a plank so as to hold a plank pair in essentially spaced-apart, parallel relationship on the ground, a cross bar of said castellated shape being disposed relative to said lateral portions at a desired height above the surface to orient and support reinforcement bars thereon.
Claim 14
Dependent Claim
85 words
Means for securing two planks of a concrete form in rigid, spaced-apart relationship comprising a bracket with a castellated shape the two lateral portions thereof each possessing a continuous rectilinear geometric shape which partially circumscribes and encloses a portion of a plank so as to hold a plank pair in essentially spaced-apart, parallel relationship on the ground, a cross bar of said castellated shape being disposed relative to said lateral portions at a desired height above the surface to orient and support reinforcement bars thereon.
Claim 15
Dependent Claim
23 words
The means for securing of claim 11, wherein the bracket further includes at least one outside lateral portion extended to effect a stake.
