Flexible form assembly

A flexible form assembly for forming a concrete structure during drying of the concrete, the flexible form assembly comprising:

• an elongated form comprising a front side for engaging the concrete and a rear side, the rear side comprising a back wall disposed between rearwardly extending top and bottom walls, the top wall being connected to a downwardly protruding upper lip, the bottom wall being connected to an upwardly protruding lower lip,
• the upper and lower lips, the top and bottom walls and the back wall forming a C-shaped pocket for receiving a stake holder,
• the stake holder comprising right and left flanges that abuttingly engage the back wall, that fit between the top and bottom walls and that are partially disposed between the upper and lower lips and the back wall,
• the stakeholder further comprising a pocket portion that is connected to and disposed between the right and left flanges, the pocket portion extending outward rearwardly to define an apex which provides a looped pocket for receiving a stake,
• the left flange comprising a vertical leg that is connected to the pocket portion and a horizontal leg that extends parallel to the pocket portion and in a spaced apart relationship with the pocket portion,
• the right flange comprising a vertical leg that is connected to the pocket portion and a horizontal leg that extends parallel to the pocket portion and in a spaced apart relationship with the pocket portion,
• the horizontal leg of the right flange being disposed opposite the pocket portion from the horizontal leg of the left flange,
• the horizontal legs of the right and left flanges being biased towards the pocket portion as they frictionally engage the top and bottom walls of the rear side of the form.

A flexible form assembly for forming a concrete structure during drying of the concrete, the flexible form assembly comprising:

• top and bottom elongated forms,
• each elongated form comprising a front side for engaging the concrete and a rear side, the rear side of each form comprising a back wall disposed between rearwardly extending top and bottom walls, the top wall of each form being connected to a downwardly protruding lower lip, the bottom wall of each form being connected to an upwardly protruding lower lip,
• the upper and lower lips, the top and bottom walls and the back wall of each form forming a C-shaped pocket for receiving a portion of a stake holder,
• the top form being stacked on the bottom form so that the front side of the top form is disposed above and flush with respect to the front side of the bottom form,
• the stake holder comprising an upper portion for slidable connection to the C-shaped pocket of the top form and a lower portion for slidable connection to the C-shaped pocket of the bottom form,
• the upper and lower portions of the stakeholder each comprising right and left flanges that abuttingly engage the back wall of their respective form, that fit between the top and bottom walls of their respective form and that are partially disposed between the upper and lower lips and the back wall of their respective form,
• the upper and lower portions of the stakeholder each comprising a pocket portion that is connected to and disposed between its respective right and left flanges, each pocket portion extending outward rearwardly to define an apex which provides a looped pocket for receiving a stake,
• the pocket portion of upper portion of the stakeholder being in alignment with and connected to the pocket portion of the lower portion of the stakeholder,
• the front side of each form comprising a front wall that is spaced apart from its respective back wall, the front and back walls of each form defining a pocket for receiving at least one aluminum reinforcing tube.
