Abstract
This invention relates to an apparatus for forming a textured cantilevered concrete edge. The apparatus includes an inner wall form adjacent to a taller outer wall form resulting in a textured edge for receiving the concrete. A L-shape liner with a horizontal foot and a vertical riser is supported by the inner wall form and braced by the outer wall form. The liner includes a textured surface on the concrete-contacting face. Combinations of straight segments and curved segments frame a perimeter for the concrete pour. This invention also relates to the method of use of the apparatus for forming a textured cantilevered concrete edge.

- This invention relates to an apparatus and method for forming and texturing concrete.
- 2. Description of Related Art
- Known concrete forms cast steps, such as for use with buildings but lack aesthetic texturing. Other concrete casting techniques include stamping brick shapes into poured horizontal concrete for driveways.
- There is a need for a concrete edge forming apparatus that results in a fixed and rigid adherence and consistent relationship between casting members to form a textured edge.
- Accordingly, it is one object of this invention to provide an apparatus for forming a textured concrete edge. It is another object of this invention to provide an apparatus for texturing the edge of the concrete.
- These and other objects of this invention are met at least in part by an apparatus for forming a concrete edge including an inner wall form and an outer wall form at least partially adjacent to the inner wall form. The inner wall form and the outer wall form combine together as a support member and frame a cantilevered shape for receiving the concrete in straight and/or curved segments.
- The apparatus includes a liner supported by at least one of the inner wall form and the outer wall form with a generally horizontal foot in combination with a generally vertical riser. The liner has a pattern in at least a portion of a concrete-contacting face for texturing the concrete. One or more fasteners secure the liner to the inner wall form, and one or more stakes anchor the apparatus during concrete forming.
- The inner wall form and outer wall form may be constructed of wood, dimensional lumber, aluminum, steel and/or foam. The liner may be constructed of polyurethane, polystyrene and/or neoprene rubber. A width of the liner may be about 1 cm to about 15 cm and a height of the liner may be about 1 cm to about 20 cm. The thickness of the riser may be about 0.5 cm to about 2.0 cm and the thickness of the foot may be about 0.25 cm to about 1.5 cm. The texture pattern may include hewn rock, brick, tile, stone and/or wood.
- The invention also includes a method of forming a concrete edge including aligning an inner wall form with an outer wall form so that a textured surface results for forming the concrete, framing at least one perimeter which may include a curve for receiving at least a portion of the concrete with an inner wall form in combination with an outer wall form, adding reinforcement within the framed perimeter, and providing a liner having a generally horizontal foot and a generally vertical riser.
- The method further includes supporting the foot of the liner on the inner wall form, supporting the riser of the liner against the outer wall form, mixing cement, aggregate, and water to form the concrete and adding a colorant to the concrete, pouring the concrete into a resulting form, leveling the concrete with a top of the outer wall form, allowing the concrete to cure or dry and removing the outer wall form, the inner wall form and the liner from the concrete.
- The method may produce stairs, curbs, patios, retaining walls, hot tubs, tiered structures and/or swimming pools.

There is no limit as to the number of tiers possible, such as for a flight of steps. Desirably, concrete 12 may includereenforcement 80, such as any of the strengthening materials described above. -
Stairs 72 generally include a plurality of stair treads 80 andstair risers 84.Stair tread 80 or generally horizontal stepping surface may be any suitable dimension, such as a width of about 20 cm to about 30 cm, preferably about 23 cm to about 28 cm.Stair riser 84 or generally vertical gain may be any suitable dimension, such a height of about 15 cm to about 25 cm, preferably about 18 to about 20 cm. The rise and run ofstairs 72 can be any suitable dimension as if supported by an appropriate stringer with allowance for desired overhang 86. - One skilled in the art and guided by the teachings herein will appreciate that any desired holes, apertures, pipes, conduits, raceways and/or any other suitable feature may be included in
concrete 12, such as for electrical power supply to low voltage lighting on a patio or a water supply to a fountain in a koi pond. - This invention also includes a method of forming a concrete edge. The method may include the following steps without limitation of order, combination, omission and/or repetition.
- The method may include the step of aligning
inner wall form 70 withouter wall form 60 so thattextured edge 14 results for formingconcrete 12 and the step of framingperimeter 54 for receiving at least a portion of concrete 12 withinner wall form 70 in combination withouter wall form 60. Optionally, the method may include the step of framing may include at least one curve and/or framing one or moreadditional perimeters 54, such as fortiered structure 74. The method may include the step of anchoring at least one ofinner wall form 70 andouter wall form 60 withstake 48 and the step of providingliner 20 havingfoot 40 andriser 42. - The method may include the step of attaching
liner 20 withfastener 44 toinner wall form 70. The method also may include the step of addingreinforcement 80 within framedperimeter 54 and the step of mixing cement, aggregate, and water to form concrete 12 and optionally adding a colorant to concrete 12. The method may further include the step of pouringconcrete 12 into texturededge 14 and the step of removing one ormore stakes 48 while pouringconcrete 12 into atiered structure 74, such as once the first layer is filled and some material has been added to the second layer to holdapparatus 10 in place and on top of the first layer. The holes from thestakes 48 may be filled withadditional concrete 12. The method also may include the step of levelingconcrete 12 with a top ofouter wall form 60 and the step of allowing concrete 12 to cure, dry and/or become solid. Another step in the method may include removingouter wall form 60,inner wall form 70 andliner 20 fromconcrete 12. - The steps of the method can be used for forming stairs, curbs, patios, retaining walls, hot tubs, swimming pools and any other suitable applications.
- While in the foregoing specification this invention has been described in relation to certain preferred embodiments thereof, and many details have been set forth for purpose of illustration, it will be apparent to those skilled in the art that the invention is susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
