Abstract
Abstract In a self-supporting concrete form of foamed polymeric material, a one piece transverse connecting member is provided which mechanically holds fastening members inserted into the form providing mechanical support for finish material such as furring strips, paneling, etc. The connecting member is formed from one piece of sheet material, preferably cold rolled steel, and comprises a central connecting web portion extending between and embedded in sidewall members of the form and first and second imperforate flat attachment flange portions extending perpendicularly from the web portion and embedded near the outer surfaces of the sidewall members for supportably receiving fastening members penetrating the sidewall members. The web portion of the connecting member comprises an array of relatively large openings to permit the flow of concrete through the form units and to provide a high strength web of metal. The connecting members may be arranged in each form unit with one connecting member midway between the longitudinal center and each end of the form unit so that, when the form units are laid up in courses in a staggered array, the connecting members of form units in succeeding courses are aligned.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
176 words
In a self-supporting form of polymeric material comprising first and second sidewall members extending in length on either side of a cavity disposed to receive flowable construction material, the combination comprising: a one piece transverse connecting member of sheet material extending between and embedded in said first and second sidewall members and comprising: a central, connecting web portion extending between said first and second sidewall members and serving to define said cavity therebetween, and having therein a plurality of openings for permitting flow therethrough of said flowable construction material; and attachment flange means integral with said central, connecting web portion, extending transversely relative to the central, connecting web portion, embedded in at least one of said sidewall members, and located relatively closely adjacent an outer side surface of one of said sidewall members in a predetermined relationship to said length of the sidewall members for enabling location thereof and fixed mechanical attachment of building materials thereto, said attachment flange means forming a substantially imperforate continuous planar surface for supportably receiving fastening members penetrating a sidewall member.
Claim 2
Dependent Claim
176 words
In a self-supporting form of polymeric material comprising first and second sidewall members extending in length on either side of a cavity disposed to receive flowable construction material, the combination comprising: a one piece transverse connecting member of sheet material extending between and embedded in said first and second sidewall members and comprising: a central, connecting web portion extending between said first and second sidewall members and serving to define said cavity therebetween, and having therein a plurality of openings for permitting flow therethrough of said flowable construction material; and attachment flange means integral with said central, connecting web portion, extending transversely relative to the central, connecting web portion, embedded in at least one of said sidewall members, and located relatively closely adjacent an outer side surface of one of said sidewall members in a predetermined relationship to said length of the sidewall members for enabling location thereof and fixed mechanical attachment of building materials thereto, said attachment flange means forming a substantially imperforate continuous planar surface for supportably receiving fastening members penetrating a sidewall member.
Claim 3
Dependent Claim
90 words
The connecting member of claim 1, wherein said attachment flange means comprises: a first attachment flange portion extending at an angle from said central connecting web portion, embedded in said first sidewall member and forming a substantially imperforate continuous planar surface for supportably receiving fastening members penetrating the first sidewall member; a second attachment flange portion extending at an angle from said central connecting web portion, embedded in said second sidewall member and forming a substantially imperforate continuous planar surface for supportably receiving fastening members penetrating the second sidewall member.
Claim 4
Dependent Claim
12 words
The connecting member of claim 1 wherein said sheet material is steel.
Claim 5
Dependent Claim
38 words
The connecting member of claim 1 wherein said plurality of openings are constructed in regularly spaced rows and columns defining between them a web of sheet material having an area less than the combined area of the openings.
Claim 6
Dependent Claim
22 words
The connecting member of claim 4, wherein said openings are arcuate and are offset from each other in adjacent rows and columns.
Claim 7
Dependent Claim
23 words
The connecting member of claim 2, wherein said first attachment flange portion and said second attachment flange portion are in opposing parallel relationship.
Claim 8
Dependent Claim
33 words
The connecting member of claim 2, wherein said web portion, said first attachment flange portion, and said second attachment flange portion are substantially in the form of rectangles coextensive with said web portion.
Claim 9
Dependent Claim
29 words
The connecting member of claim 2, wherein said first attachment flange portion and said second attachment flange portion extend at substantially right angles from said central connecting web portion.
Claim 10
Dependent Claim
26 words
The form of claim 1, wherein said transverse connecting member is embedded in the form midway between a longitudinal center and an end of the form.
Claim 11
Dependent Claim
44 words
The form of claim 1, wherein said transverse connecting member is embedded in the first and second sidewall members in combination with a second similar transverse connecting member, each connecting member being embedded midway between a longitudinal center and an end of the form.
Claim 12
Dependent Claim
161 words
In a self-supporting form of polymeric material comprising first and second sidewall members extending in length on either side of a cavity disposed to receive flowable construction material, the combination comprising: a first one piece transverse connecting member of sheet material extending between and embedded in said first and second sidewalls, having a perforate central web portion having top and bottom edges and a pair of substantially imperforate attachment flanges on either side of said central web portion extending continuously between said top and bottom edges and located relatively closely adjacent outer side surfaces of the sidewall members; and a second one piece transverse connecting member, substantially identical to said first one piece connecting member and embedded in said first and second sidewalls a predetermined distance from the first one piece transverse connecting member so that, in a staggered array of a plurality of said self-supporting forms, said first and second one piece transverse connecting members are aligned between succeeding courses.
Claim 13
Dependent Claim
161 words
In a self-supporting form of polymeric material comprising first and second sidewall members extending in length on either side of a cavity disposed to receive flowable construction material, the combination comprising: a first one piece transverse connecting member of sheet material extending between and embedded in said first and second sidewalls, having a perforate central web portion having top and bottom edges and a pair of substantially imperforate attachment flanges on either side of said central web portion extending continuously between said top and bottom edges and located relatively closely adjacent outer side surfaces of the sidewall members; and a second one piece transverse connecting member, substantially identical to said first one piece connecting member and embedded in said first and second sidewalls a predetermined distance from the first one piece transverse connecting member so that, in a staggered array of a plurality of said self-supporting forms, said first and second one piece transverse connecting members are aligned between succeeding courses.
