Abstract
Abstract A concrete column form clamp and method. The clamp includes a plurality of frame members adapted to have form panels secured thereto, each of said frame members comprising a plurality of frame sections, and a plurality of elongated rod members, each of said rod members having hingedly mounted thereon adjacent frame sections of each of said frame members and extending between all of said frame members whereby corresponding sections of said frame members are ganged for articulated movement and said form clamp may be handled as a unit. The form clamp includes spacer means for maintaining adjacent frame members in spaced relationship to one another. Locking means is provided whereby the frame members may be selectively locked into a substantially rigid polygonal configuration.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
95 words
A form clamp for concrete column molds comprising, in combination: a plurality of frame members adapted to have form panels secured thereto, each of said frame members comprising a plurality of frame sections; and a plurality of elongated rod members, each of said rod members having hingedly mounted thereon adjacent frame sections of each of said frame members and extending between all of said frame members whereby corresponding sections of said plurality of frame members are ganged for articulated movement about said elongated rod members and said form clamp may be handled as a unit.
Claim 2
Dependent Claim
95 words
A form clamp for concrete column molds comprising, in combination: a plurality of frame members adapted to have form panels secured thereto, each of said frame members comprising a plurality of frame sections; and a plurality of elongated rod members, each of said rod members having hingedly mounted thereon adjacent frame sections of each of said frame members and extending between all of said frame members whereby corresponding sections of said plurality of frame members are ganged for articulated movement about said elongated rod members and said form clamp may be handled as a unit.
Claim 3
Dependent Claim
35 words
The form clamp according to claim 1 additionally comprising spacer means disposed on at least one of said rod members between adjacent frame members to maintain said frame members in spaced relationship to one another.
Claim 4
Dependent Claim
47 words
The form clamp according to claim 2 wherein said spacer means comprises a plurality of tubular members slidably disposed about at least one of said rods, at least one of said tubular members being in endwise abutting engagement with said frame members to maintain said spaced relationship.
Claim 5
Dependent Claim
20 words
The form clamp according to claim 3 additionally comprising bracket means connected to at least one of said tubular members.
Claim 6
Dependent Claim
21 words
The form clamp according to claim 3 additionally comprising outrigger support means attached to at least one of said tubular members.
Claim 7
Dependent Claim
22 words
The form clamp according to claim 1 additionally comprising means for selectively locking said frame members into a substantially rigid polygonal configuration.
Claim 8
Dependent Claim
64 words
The form clamp according to claim 6 wherein said frame members each comprise four frame sections, the sections of each frame member adapted to be locked into a rectangular configuration by said locking means, said sections each having formed therein a plurality of spaced throughbores through which said elongated rod members are Adapted to selectively project thereby varying the size of the rectangular configuration.
Claim 9
Dependent Claim
71 words
The form clamp according to claim 7 wherein said elongated rod members are disposed at three corners of said rectangular configuration, said locking means being disposed at the fourth corner whereby the sections of each frame member may be pivoted about said elongated rod members upon unlocking of said locking means at said fourth corner to lie along a substantially flat plane thereby facilitating attachment or detachment of said form panels.
Claim 10
Dependent Claim
48 words
The form clamp according to claim 6 wherein at least some of said sections of each frame member have a plurality of spaced throughbores formed therein through which said elongated rod members are adapted to selectively project whereby the rectilinear configuration of said frame members may be varied.
Claim 11
Dependent Claim
35 words
The form clamp according to claim 9 additionally comprising spacer means disposed on at least one of said rod members between adjacent frame members to maintain said frame members in spaced relationship to one another.
Claim 12
Dependent Claim
61 words
The form clamp according to claim 10 wherein said spacer means comprises tubular members disposed about at least one of said elongated rod members between said frame members, said tubular members having an external diameter greater than the diameter of each of said spaced throughbores whereby said tubular means is in endwise abutment with said frame members adjacent to said throughbores.
Claim 13
Dependent Claim
35 words
The form clamp according to claim 6 additionally comprising secondary locking means for releasably locking said frame members in a second substantially rigid polygonal configuration to facilitate the transport thereof from one location to another.
