Abstract
The present invention relates to a form for molding building components, such as columns, having a desired size, shape, and surface features from solidifying building materials such as concrete. The form is sculpted from a plastic material such as polystyrene or urethane. The cylinder is hollowed so that the interior of the resulting form has the size, shape, and surface features of the desired building component.
Claims9
A form for casting a building component of desired size, shape and surface features from castable material comprising:
- a plastic material having an open interior volume of the desired size, shape and surface features, the interior volume being defined by the plastic material extending from an exterior surface to an interior surface defining the interior volume, directly against which the castable material is disposed without an intervening layer, the exterior surface receiving supporting means for maintaining the form in a desired position;
- supporting means for maintaining the form in the desired position, which comprises a plurality of supporting members, and the exterior surface of the plastic material includes a corresponding plurality of channels receiving the supporting members;
- at least one tightenable band surrounding the exterior surface of the plastic material and the supporting members;
- means for tightening the tightenable band;
- and
- retaining pads disposed between the tightenable band and the supporting members.
