         [0012]     The term “blockout”, as used in this specification includes any indentation formed into the exterior surface of a concrete tilt-up panel at the time it is poured.  
         [0013]     The term “chamfer” as used in this specification includes a beveled edge, a groove or fluting formed into the exterior surface of a concrete tilt-up panel at the time it is poured.  
         [0014]     The term “concrete” as used in this specification includes Portland Cement concrete and similar material(s).  
         [0015]     The term “concrete tilt-up panel”, as used in this specification, includes any concrete slab or panel that is created by pouring fluid concrete into forms set out upon a hardened concrete floor surface. After curing, the panel side-forms are removed from the panel sides and the resulting tilt-up panel is removed from the floor surface and utilized as a component of the interior or exterior walls in the construction of a concrete structure.  
         [0016]     The terms “edge form”, “side panel” and “panel form”, as used in this specification, include any solid material that is capable of being installed on top of a hardened concrete floor surface to serve as the edge or side of any form into which fluid concrete or other substance may be poured during the fabrication of a concrete tilt-up panel or similar item. For ease of reference, as used in this specification, the term “edge form” shall mean and include the terms “edge form”, “side form”, “panel form” and any other term designating a device suitable for such same or similar purpose.  
         [0017]     The term “expansion joint material” as used in this specification is any suitable material that may be utilized to fill a gap of typically from ½ inch to 1 inch, commonly referred to as “expansion joints”, which are fabricated, formed or cut into structural surfaces at pre-determined intervals to allow for the naturally occurring expansion and contraction of the component materials which occurs as a result of changing temperatures.  
         [0018]     The term “form-liner” or “form liner panel” as used in this specification includes any shaped material, including plastic, metal, compressed fiber, wood or rubber, that is attached to the inside of an upright poured-in-place concrete wall form to render a design, impression or shape within the exterior surface(s) of the completed poured-in-place concrete wall.  
         [0019]     The term “MDF” as used in this specification is a construction industry abbreviation for “Medium Density Fiberboard” and is a type of hardboard which is made from wood fibers glued under heat and pressure.  
         [0020]     The terms “reveal”, “reveal strip”, “feature strip”, “chamfer strip”, “detail strip”, “rustication strip” and “MDF strip”, as used in this specification, include any linear groove or indentation formed into the exterior surface of a concrete tilt-up panel at the time it is poured. For ease of reference, as used in this specification, the term “reveal strip” shall mean and include the terms “feature strip”, “blockout”, “chamfer strip”, “reveal strip”, “detail strip”, “rustication strip” and “MDF strip” and any other term designating a device suitable for such same or similar purpose.  
         [0021]     The term “reveal” or “reveal strip” as used in this specification also includes any linear shaped material, including plastic, metal, compressed fiber, wood or rubber, that is attached to the inside of an upright poured-in-place concrete wall form to render a design, impression or shape within the exterior surface(s) of the completed poured-in-place concrete wall.  
         [0022]     The term “reveal” as used in this specification also includes the finished linear impression or indented shape within the surface of a tilt-up wall panel.  
         [0023]     The terms “reveal strip form”, “feature strip form”, “chamfer strip form”, “detail strip form”, “rustication strip”, as used in this specification, includes any solid material, including wood, plastic, metal or the like, that is capable of being shaped or sized and affixed to the surface of a concrete floor or other flat surface within the confines of an edge form. When fluid concrete is poured into the tilt-up panel form and over said reveal strip form, an impression or indentation is created in the surface of the tilt-up panel facing the floor surface in the transposed shape of the reveal strip form. Upon curing, the concrete tilt-up panel is lifted off of the floor surface by mechanical means and the reveal strip form remains attached to the floor, leaving an indented “reveal strip” or “reveal” in the space previously occupied by the reveal strip form during the pour.  
         [0024]     The term “tilt-up structure” as used in this specification includes any structure constructed by means of utilizing poured concrete wall panels which have been formed on a horizontal surface and subsequently “tilted” or lifted into position to form the walls of said structure.  
         [0025]     In modern times it has become common practice in the building of tilt-up structures to begin construction by pouring a concrete floor slab. When the floor slab surface has cured, edge forms for the concrete tilt-up panels are laid out on top of the floor surface. Fluid concrete is thereafter poured into the edge forms. When the concrete tilt-up panels have fully cured, they are lifted off of the floor surface into place by mechanical means and bolted together along the perimeter of the floor surface to form the exterior walls of the structure. Concrete tilt-up panels may likewise be used to construct some or all of the interior walls of a concrete structure.  
         [0026]     To prevent a freshly-poured concrete tilt-up panel from adhering to the floor surfaces, a non-stick concrete releasing agent, commonly referred to as “bond-breaker”, is first applied to the floor surface before the pouring of the concrete tilt-up panel takes place.  
         [0027]     In the event that the design plans and specifications call for the installation of a reveal strip within or along a portion of the exterior surface of a concrete tilt-up panel, workers will typically install a reveal strip form inside the perimeter of the edge form prior to the concrete pour. The reveal strip form must be securely attached to the floor surface so as to prevent movement and leakage during the concrete pour.  
         [0028]     At the present time, two principal methods are utilized to secure the edge forms and/or reveal strip forms to the concrete floor surface during the fabrication of a concrete tilt-up panel:  
       Method 1  
       [0029]     An edge form and/or reveal strip form is located and marked on the surface of a concrete floor. Holes are drilled through the base surface of the edge form and/or reveal strip form into the concrete floor surface. The edge form and/or reveal strip form is temporarily removed from the floor surface and wooden or fiber pegs are inserted into the drilled holes in the concrete floor surface. The reveal strip form is then re-positioned in place and secured to the floor surface by means of nails or screws driven into the pegs, or driven directly into the holes. In a typical 40,000 square foot structure, more than 5,000 holes are drilled to secure the edge forms and reveal strip forms.  
         [0030]     Following the pouring and curing of the concrete tilt-up panels and their subsequent removal from the concrete floor surface, the edge form and/or reveal strip form is removed from the concrete floor and each hole in the surface of the concrete floor is patched with an epoxy sealant. Visible nail head indentations remaining in the surface of the tilt-up panel are filled or smoothed.  
         [0031]     Disadvantages of using this installation method include high labor costs to install and remove the forms and repair the concrete surfaces, extended completion times and permanent damage to the concrete floor surface resulting from the drilling and nailing process, including spalling of the floor surface adjacent to the drilled penetrations which may be further aggravated by heavy fork-lift traffic and sub-freezing weather conditions.  
       Method 2  
       [0032]     An edge form and/or reveal strip form is located and marked on the surface of a concrete floor slab. The edge form and/or reveal strip form is temporarily removed from the floor surface. A two-sided adhesive tape is applied to the base surface of the edge form and/or reveal strip form facing the concrete floor. Acetone and other solvents are required to remove the “bond-breaker” substance from the surface of the concrete floor over the areas where the edge form and/or reveal strip form is to be “taped” so that the adhesive material will stick. The edge form and/or reveal strip form with the two-sided adhesive tape affixed to it is then re-positioned upon the concrete floor surface, followed by the pouring of the fluid concrete into the space created by the edge form. Following the curing of the concrete tilt-up panel and its removal from the floor surface, glue residue from the tape adhesive must be removed from all concrete surfaces.  
         [0033]     Disadvantages of using this installation method include high material and labor costs, extended completion times and deposit of adhesive residues that may be non-removable on some surfaces, resulting in permanent appearance flaws in the finished tilt-up panel or concrete floor, including unwanted lines, especially in connection with the use of colored concrete sealers. Further, the adherence qualities of the two-sided tape is adversely affected by moisture and humidity. The use of two-sided-tape in attaching edge forms and/or reveal strip forms is limited to dry weather projects and is utilized most effectively only in the southern-tier states.  
         [0034]     Form-liner is used in the construction of poured-in-place upright concrete walls to render a design, impression or shape within the exterior surface(s) of the completed poured-in-place concrete wall. Present construction methods for affixing form-liner material to the inside wall of a pour-in-place concrete form is to utilize screws, nails or panel adhesives, such as silicon adhesives, “Liquid Nails”™, and other tube-dispensed adhesive products.  
         [0035]     Disadvantages of the nailing or screwing method include the need to have laborers working on both sides of the forms during the installation process; the unavoidable creation of holes in the forms; the unavoidable creation of nail-head impressions in the finished concrete surfaces which require patching; time-consuming and labor-intensive removal and clean-up; buckling and warping of the forms around the nail or screw-heads.  
         [0036]     Disadvantages of using tube-dispensed adhesive products to affix panel forms include time-consuming and labor-intensive removal and clean-up; sensitivity to moisture and humidity, resulting in failure of the adhesive and bulging; and sensitivity to chemicals in or upon the concrete forms resulting in failure of the adhesive and subsequent bulging, and messiness and difficulty in removing residue.  
         [0037]     Reveal strips (or “reveal”), are also used in the construction of poured-in-place upright concrete walls to render a linear design, impression or shape within the exterior surface(s) of the completed poured-in-place concrete wall. Present construction methods for affixing reveal strip material to the inside wall of a pour-in-place concrete form is to utilize screws, nails or panel adhesives, such as silicon adhesives, “Liquid Nails”™, and other tube-dispensed adhesive products.  
         [0038]     Disadvantages of the nailing or screwing method include the need to have laborers working on both sides of the forms during the installation process; the unavoidable creation of holes in the forms; the unavoidable creation of nail-head impressions in the finished concrete surfaces which require patching; time-consuming and labor-intensive removal and clean-up; buckling and warping of the reveal strips around the nail or screw-heads.  
         [0039]     Disadvantages of using tube-dispensed adhesive products to affix reveal strips include time-consuming and labor-intensive removal and clean-up; sensitivity to moisture and humidity, resulting in failure of the adhesive and bulging; and sensitivity to chemicals in or on the concrete forms resulting in failure of the adhesive and subsequent bulging; messiness and difficulty in removing residue.  
         [0040]     During construction of certain structures, such as bridges, buildings, roadways and other structures, gaps of typically from ½ inch to 1 inch, commonly referred to as “expansion joints”, are fabricated, formed or cut into structural surfaces at pre-determined intervals to allow for the naturally occurring expansion and contraction of the component materials which occurs as a result of changing temperatures. Whenever an expansion joint is called to be located between components of a structure or slab, it is necessary to fill in the gap with an expandable and contractible material (“expansion joint material”) that is capable of sealing the joint from penetrations of dirt, liquid, air and other elements.  
         [0041]     To install expansion joint material, it is customary practice in the construction industry to attach some type of expansion joint material such as asphalt impregnated board, fiber board, rubber expansion joint filler, self-expanding cork, foam, closed-cell neoprene or other material(s) to the material surface of the first completed edge with nails or other penetrating fastening devices and then locate, pour or position the corresponding edge of the second material surface tightly against the previously installed expansion joint material, thus forming a completed expansion joint.  
         [0042]     Disadvantages of using nails or other penetrating fastening devices to affix expansion joint material to the surface of a wall or slab edge include increased labor expense; work delay attributable to the time needed to nail the expansion joint material; where concrete is the material, spalling and other damage to the surface; and bowing or waving of the expansion joint material around nails or other fastening devices.  
         [0043]     During the construction of concrete floor slabs, “expansion joints”, are frequently saw-cut into freshly-poured concrete surfaces at pre-determined intervals to allow for the naturally occurring expansion and contraction of the concrete material which occurs as a result of changing temperatures.  
         [0044]     A common undesirable consequence of saw-cutting is that the cutting process produces spalling and ragged edges along the saw-cut edges of concrete surfaces.
