Abstract
Abstract A wall form arrangement of the type used in forming composition walls, such as concrete walls, which includes a pair of vertically stacked wall forms. Each wall form has horizontally extending angle iron walers on its outer side. The stacked wall forms are reinforced by a vertically extending channel positioned against the outer side of the forms and having downwardly facing hooks thereon engaging the angle iron walers and drawing the channel against the walers. A hook at the lower end of the channel is adapted to be drawn upwardly to interengage the bottom waler on the lower wall form to secure the two wall forms in rigidly clamped vertically aligned relation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
A wall forming arrangement comprising in combination, a pair of wall forms stacked vertically edgewise one upon the other, said stacked wall forms having coplanar inner and outer faces and having on the outer faces thereof a plurality of horizontally extending reinforcing walers, said walers being spaced apart vertically at regular intervals on said stacked walls, a vertical stiffener comprising a rigid member extending vertically against the outer faces of said stacked panels and having a plurality of vertically spaced hooks fixedly mounted thereon, all of said hooks facing toward one end of the rigid member and interengaged with the horizontally extending walers, an additional hook adjacent said one end of the rigid member and movably mounted thereon, said additional hook facing toward the opposite end of said rigid member and engaging a horizontally extending waler on one of said wall forms and means for drawing said movable hook and said fixed hooks relatively toward one another to apply a vertical clamping force to the wall sections while the outer faces thereof are retained in coplanar relation by said rigid member.
Claim 2
Dependent Claim
181 words
A wall forming arrangement comprising in combination, a pair of wall forms stacked vertically edgewise one upon the other, said stacked wall forms having coplanar inner and outer faces and having on the outer faces thereof a plurality of horizontally extending reinforcing walers, said walers being spaced apart vertically at regular intervals on said stacked walls, a vertical stiffener comprising a rigid member extending vertically against the outer faces of said stacked panels and having a plurality of vertically spaced hooks fixedly mounted thereon, all of said hooks facing toward one end of the rigid member and interengaged with the horizontally extending walers, an additional hook adjacent said one end of the rigid member and movably mounted thereon, said additional hook facing toward the opposite end of said rigid member and engaging a horizontally extending waler on one of said wall forms and means for drawing said movable hook and said fixed hooks relatively toward one another to apply a vertical clamping force to the wall sections while the outer faces thereof are retained in coplanar relation by said rigid member.
Claim 3
Dependent Claim
40 words
The combination called for in claim 1 wherein said walers comprise at least in part the outer surfaces of said wall forms and said hooks are adapted to draw the rigid member toward the outer faces of the wall forms.
Claim 4
Dependent Claim
38 words
The combination called for in claim 1 wherein said walers each include vertically extending flange portions which are substantially coplanar with the outer faces of the wall forms and with which said movable and fixed hooks are engaged.
Claim 5
Dependent Claim
88 words
The combination called for in claim 3 wherein said movable hook is slidably mounted on said rigid member for movement lengthwise thereof whereby said rigid member is adapted to be positioned against the outer faces of said wall forms and shifted vertically in the direction of said one end to interengage the fixed hooks thereon with the vertical flange portions of the walers and thereafter said movable hook is adapted to be shifted vertically in the opposite direction to interengage with the vertical flange portion of another waler.
Claim 6
Dependent Claim
55 words
The combination called for in claim 4 wherein said rigid member comprises a channel-shaped section having a generally flat wall connecting a pair of parallel sidewalls of the channel, said flat wall being adapted to be positioned against the outer face of the wall forms and said hooks projecting inwardly from said generally flat wall.
Claim 7
Dependent Claim
27 words
The combination called for in claim 5 wherein the hooks on the rigid member are secured to the laterally outer faces of the sidewalls of the channel.
Claim 8
Dependent Claim
26 words
The combination called for in claim 5 wherein said movable hook comprises a portion of a bracket slideably arranged within said one end of the channel.
Claim 9
Dependent Claim
69 words
The combination called for in claim 7 wherein said bracket includes a generally horizontally extending anchor plate, a screw extending through said anchor plate, a second plate on said channel spaced from said one end theReof and through which said screw is adapted to extend and a nut on the second anchor plate for enabling the movable hook to be drawn toward the other hooks by tightening said screw.
