Abstract: A form assembly is provided for forming a concrete structure during setting of the concrete. Included in the form assembly are a first barrier assembly having a first inner surface and a first outer surface; a second barrier assembly having a second inner surface, a second outer surface, an upper barrier, and a lower barrier. A channel is defined by the first and second inner surfaces of the first and second barrier assemblies for pouring the concrete into the channel. The second barrier assembly includes at least one height adjustment assembly being connected at one end to the upper barrier, and at an opposite end to the lower barrier such that the upper barrier vertically reciprocates along a vertical guide of the upper barrier relative to the lower barrier for adjusting an overall height of the form assembly using the at least one height adjustment assembly.

Abstract: A radius forming system has at least one flexible form member with a plurality of stake pockets. The stake pockets are each formed in a single piece having a first and second opening therethrough arranged to receive a fastening element and an intermediate portion having an enclosing shape defining a stake holder. The intermediate portion has at least one opening therethrough and a locking member is received in the opening arranged to engage a stake positioned in the stake holder. The form member has a plurality of vertically aligned pairs of openings spaced along the length of the form member. A plurality of fastening elements are received in the various openings in the form member and the stake pockets to hold the form member and stake pockets together.

Abstract: An overhead hanger unit for concrete forms, with a first hanger form having a first portion engagable with a first curb form and a second portion extending from the first portion, and a second hanger form having a first portion engagable with a second curb form and a second portion extending from the first portion. A pin may be carried on the second portion of the first hanger form and a slot may be formed in the second portion of the second hanger form, wherein the second portion of the second hanger form may be aligned with the second portion of the first hanger form and the pin engaged with the slot. A coupling device may be engagable with the pin to secure the first hanger form to the second hanger form at a selected position such that a distance from the first curb form to the second curb form may be adjusted by an amount substantially equal to a length of the slot.

Abstract: A form assembly for forming a concrete structure during drying of the concrete. The form assembly is formed of an elongated plastic form having a front wall for engaging the concrete and a rear wall. The front wall is spaced apart from the back wall to define a pocket for receiving at least one connecting member. The connecting member is secured in the pocket to project a distance beyond an end of the form. A slidable stake holder may also be provided to slide in a C-shaped pocket in the form. The stake holder has right and left flanges that abuttingly engage the rear wall and at least one preformed nail hole is provided in each of the right and left flanges.

Abstract: A flexible form assembly for forming concrete structures during setting of the concrete is provided. The flexible form assembly includes an elongated form having a front side for engaging the concrete and a rear side. The rear side includes a back wall disposed between two rearwardly extending top and bottom walls which, in turn, are connected to downwardly and upwardly protruding lips respectively to form a C-shaped pocket for receiving a stake holder. The stake holder includes right and left flanges that abuttingly engage the back wall and that fit between the top and bottom walls and that are partially disposed between the upper and lower lips and the back wall. The stake holder further comprises a pocket portion that is connected to and disposed between right and left flanges. The pocket portion extends outwardly to define an apex which provides a looped pocket for receiving a stake.

Abstract: A device for screeding and finishing concrete pavements having an elongate sectional framework, turnbuckles between framework sections to provide a crown or sag, a rotating shaft with eccentric weights driven by an internal combustion engine to impart vibration, hydraulic pumps and motors driving winches for self-propulsion of the device across the concrete. The screed bars are hollow rectangular members having two useable wearing surfaces. The screed bars may be rotated to bring their second wearing surfaces into contact with the concrete.
