Cantilevered and textured concrete form

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.

1 . An apparatus for forming concrete, the apparatus comprising:
 an inner wall form retaining at least a portion of the concrete;   an outer wall form at least partially adjacent to the inner wall form, the inner wall form and the outer wall form together frame a cantilevered shape for receiving the concrete;   a liner at least partially disposed within the cantilevered shape and supported by at least one of the inner wall form and the outer wall form, the liner comprising a generally horizontal foot in combination with a generally vertical riser, the liner having a pattern in at least a portion of a concrete face for texturing the concrete.   
   
   
       2 . The apparatus for forming concrete of  claim 1 , further comprising at least one fastener securing the liner to the inner wall form. 
   
   
       3 . The apparatus for forming concrete of  claim 1 , wherein the inner wall form and the outer wall form comprise at least one of the group consisting of wood, dimensional lumber, aluminum, steel and foam. 
   
   
       4 . The apparatus for forming concrete of  claim 1 , wherein the liner comprises at least one of the group consisting of polyurethane, polystyrene and neoprene rubber. 
   
   
       5 . The apparatus for forming concrete of  claim 1 , wherein the liner has a generally L-shape cross section with the pattern disposed on the riser opposite the outer wall form. 
   
   
       6 . The apparatus for forming concrete of  claim 1 , wherein a width of the liner is about 1 cm to about 15 cm. 
   
   
       7 . The apparatus for forming concrete of  claim 1 , wherein a height of the liner is about 1 cm to about 20 cm. 
   
   
       8 . The apparatus for forming concrete of  claim 1 , wherein the texture of the pattern is selected from the group consisting of hewn rock, brick, tile, stone, wood and combinations thereof. 
   
   
       9 . The apparatus for forming concrete of  claim 1 , wherein the apparatus forms an edge selected from the group consisting of straight, curved and combinations thereof. 
   
   
       10 . The apparatus for forming concrete of  claim 1 , further comprising at least one stake anchoring at least a portion of the apparatus during concrete forming. 
   
   
       11 . A cantilevered masonry form comprising:
 a generally L-shape liner textured on at least a portion of a forming surface;   a support member backing the L-shape liner; and   a fastener attaching the L-shape liner to the support member.   
   
   
       12 . The masonry form of  claim 11 , wherein:
 the liner has a generally vertical element and a generally horizontal element;   the generally vertical element has a thickness of about 0.5 cm to about 2.0 cm; and   the generally horizontal element has a thickness of about 0.25 cm to about 1.5 cm.   
   
   
       13 . A method of forming a concrete edge comprising:
 aligning an inner wall form with an outer wall form so that a cantilevered shape results for forming the concrete;   framing a perimeter for receiving at least a portion of the concrete with an inner wall form in combination with an outer wall form;   providing a liner having a generally horizontal foot and a generally vertical riser;   supporting the foot of the liner on the inner wall form;   supporting the riser of the liner against the outer wall form;   pouring concrete into the cantilevered shape;   allowing the concrete to cure; and   removing the outer wall form, the inner wall form and the liner from the concrete.   
   
   
       14 . The method of forming a concrete edge of  claim 13 , further comprising:
 mixing cement, aggregate, and water to form the concrete; and   adding a colorant to the concrete.   
   
   
       15 . The method of forming a concrete edge of  claim 13 , wherein the concrete edge forms at least one of group consisting of stairs, curbs, patios, retaining walls, hot tubs and swimming pools. 
   
   
       16 . The method of forming a concrete edge of  claim 13 , wherein the framing a perimeter includes at least one curve. 
   
   
       17 . The method of forming a concrete edge of  claim 13 , further comprising:
 anchoring at least one of the inner wall form and the outer wall form with a stake.   
   
   
       18 . The method of forming a concrete edge of  claim 13 , further comprising:
 framing a second perimeter and forming a tiered structure.   
   
   
       19 . The method of forming a concrete edge of  claim 13 , further comprising:
 leveling the concrete with a top of the outer wall form.   
   
   
       20 . The method of forming a concrete edge of  claim 13 , further comprising:
 adding reinforcement within the framed perimeter.
