Abstract
Abstract An object retention form liner is described for use in holding and transferring objects, such as thin bricks to the finished surface of concrete structures. The form liner is produced by strategically positioning a plurality of bricks in a face-up position in a flat, shallow mold. Recesses sized to fit the bricks can be provided in the surface of the mold with a sealing ridge provided between each of the recesses. The bricks are positioned in the recesses and a liquid elastomeric material is poured into the mold to cover the bricks. Reinforcing fiberglass mesh can be embedded in the elastomeric material to provide additional tensile strength to the liner. Upon setting, the liner and retained bricks are removed from the mold and the liner can be stored, shipped or used in concrete construction. The liners are attached to the inside surface of concrete forms and the bricks are held rigidly in place while the concrete is poured and sets. Upon removal of the form and liner, the bricks remain permanently embedded in the surface of the concrete structure providing an improved aesthetic appearance. Through the gasketing effect that is obtained by embedding the outer surface of the bricks in the elastomeric material, the necessity for cleaning or repairing the surface in the finished wall is eliminated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A method of making an object retention form liner for use in embedding objects having a face surface which is to be exposed in the finished surface of a concrete structure, the method including the steps of: a) positioning a shallow tray on a horizontal support surface, the inside dimensions of said tray corresponding to the finished outside dimensions of said form liner; b) placing objects in said tray in a spaced array which is desired for the finished surface of the concrete structure, said objects being positioned in a face upward configuration in said tray; c) pouring a liquid elastomeric material into said tray to a depth which covers said objects; d) curing said elastomeric material to form a form liner containing said objects; and e) removing said form liner from said tray with said objects firmly retained in said liner for use in construction of a concrete structure.
Claim 2
Independent Claim
150 words
A method of making an object retention form liner for use in embedding objects having a face surface which is to be exposed in the finished surface of a concrete structure, the method including the steps of: a) positioning a shallow tray on a horizontal support surface, the inside dimensions of said tray corresponding to the finished outside dimensions of said form liner; b) placing objects in said tray in a spaced array which is desired for the finished surface of the concrete structure, said objects being positioned in a face upward configuration in said tray; c) pouring a liquid elastomeric material into said tray to a depth which covers said objects; d) curing said elastomeric material to form a form liner containing said objects; and e) removing said form liner from said tray with said objects firmly retained in said liner for use in construction of a concrete structure.
Claim 3
Dependent Claim
47 words
A method of making an object retention form liner as described in claim 1 which further includes a step of embedding a tensional member in the elastomeric material while it is still in a liquid state to stabilize the liner and aid the retention of said objects.
Claim 4
Dependent Claim
33 words
A method of making an object retention form liner as described in claim 2 wherein said tensional member is a woven mesh material that is submerged in the surface of said elastomeric material.
Claim 5
Dependent Claim
90 words
A method of making an object retention form liner as described in claim 1 which further includes a step of positioning a template in said tray prior to placing said objects, said template having a plurality of recesses sized to closely fit said objects and ridges formed between each of said recesses, said ridges being formed to produce a seal in the poured elastomeric material between said objects so as to provide a gasket effect around each object to prevent concrete from migrating to the face surface of said objects.
Claim 6
Dependent Claim
23 words
A method of making an object retention form liner as described in claim 1 wherein the elastomeric material is a pourable polyurethane elastomer.
Claim 7
Dependent Claim
33 words
A method of making an object retention form liner as described in claim 1 wherein the elastomeric material fills the tray to a depth within the range of 1-4 mm above the objects.
Claim 8
Dependent Claim
54 words
A method of making an object retention form liner as described in claim 4 wherein the ridges of the template are formed to produce a convex lip along the space in the liner between the objects to produce a concave grout line between the objects embedded in the finished surface of the concrete structure.
Claim 9
Dependent Claim
37 words
A method of making an object retention form liner as described in claim 1 wherein the placed objects are thin bricks having one or more undercut grooves on the surface opposite the face surface of the brick.
