ABSTRACT:
A universal multi-part form for casting concrete parapets and the like having front and rear surfaces and opposite side and end surfaces with the dimensions between end surfaces varying between parapets. The form comprises a stationary base and support means which has a horizontal upwardly exposed surface for forming a front parapet surface. A first or base end surface form member is mounted on the stationary base and has an upright inner surface shaped in accordance with the parapet base contour. Similar but opposite side surface form members are elongated and slidably mounted on the base with inner surfaces conforming to the desired side surfaces of the parapets. A second or top end surface form member is supported by the base and connected at opposite ends with the side members for adjustable movement therewith. Connections between the top form member and the side form members accommodate movement of the three members in unison with the top member parallel with the base form member or in angular relationship therewith for parapets with inclined top surfaces. Thus, parapets with varying end-to-end or top-to-bottom dimensions can be accommodated and parapets with inclined top surfaces can be cast as desired.
