Abstract
Abstract This application discloses forms of the type used to contain concrete or like plastic material during hardening. Cantilevertype forms are shown having vertical structural members which support the face of the form from the back and extend below the form to engage the face of a previously poured layer. The vertical members are secured to anchors set into the prior layer, and anchors penetrate the vertical members and the form to be set into the layer being poured. Replacement inserts are provided along the vertical members in the face of the form whereby the anchor devices may extend through the from at any position, then the inserts replaced for the next pour so that the form is not perforated.

Claim 5
Dependent Claim
69 words
A form for use in pouring concrete or the like, according to claim 3, wherein: the second anchor means for setting in the concrete or the like being poured is positioned vertically above the first anchor means which may be positioned above the lower edge of the panel, the first anchor means being positioned at an angle to penetrate the top surface of a previously poured layer of concrete.
Claim 6
Dependent Claim
42 words
A form for use in pouring concrete or the like, according to claim 1, wherein: the vertical structural members are positioned behind the transverse structural members, and both of said anchor means extend through the vertical structural members and are fastened thereto.
Claim 7
Dependent Claim
165 words
A form of the vertical cantilever type for use in containing plastic material for hardening thereof, comprising: panel means providing the face of the form, a plurality of transverse and vertical structural members composed of steel or the like extending along the back of said panel means, the panel being attached to said structural members, means adjacent the lower part of the panel for securing at least one of the vertical structural members to first anchor means extending into an area below the plastic material to be hardened, and a plurality of replaceable inserts positioned in the panel means generally aligned with a vertical structural member, the inserts being spaced between transverse structural members whereby the transverse structural members extend along the panel without interruption, the inserts being adapted to receive second anchor means penetrating therethrough for setting in the plastic material to be hardened, the inserts being comprised of wood or like expandable material which is easily bored for positioning of the anchor means.
Claim 8
Dependent Claim
165 words
A form of the vertical cantilever type for use in containing plastic material for hardening thereof, comprising: panel means providing the face of the form, a plurality of transverse and vertical structural members composed of steel or the like extending along the back of said panel means, the panel being attached to said structural members, means adjacent the lower part of the panel for securing at least one of the vertical structural members to first anchor means extending into an area below the plastic material to be hardened, and a plurality of replaceable inserts positioned in the panel means generally aligned with a vertical structural member, the inserts being spaced between transverse structural members whereby the transverse structural members extend along the panel without interruption, the inserts being adapted to receive second anchor means penetrating therethrough for setting in the plastic material to be hardened, the inserts being comprised of wood or like expandable material which is easily bored for positioning of the anchor means.
Claim 9
Dependent Claim
35 words
A form for use in containing plastic material or the like, according to claim 6, wherein: the inserts are positioned along a vertical structural member, the second anchor means extending through the vertical structural member.
Claim 10
Dependent Claim
38 words
