Abstract: The apparatus may include moveable partitions that may be positioned in a side-by-side arrangement. The partitions may be moveable with respect to each other to facilitate installation of liners and reinforcing material and the removal of the concrete structures from the apparatus after the concrete has hardened. Cavities may be defined between the partitions for receiving concrete to form panels for use in barriers, walls and other structures. Removable liners may be temporarily secured to the partitions in a manner that does not comprise the integrity of the liners. Further, the liners may be secured to the partitions utilizing a combination of mechanical and magnetic coupling. The liners may also include a molded portion for forming surface treatments in the panels. Removable bulkheads placed into the cavities allow the dimensions of the cavities to be variable to thereby permit the formation of panels of different dimensions using the same partitions.

Abstract: The apparatus may include a cavity for forming pre-cast concrete structures, such as concrete columns. The cavity may be defined by a base member and two opposing side members. The two opposing side members may be pivotally interconnected to the base member such that the two opposing side members are moveable between a ready-to-use position and a release position. Projection members may be placed into the cavity to form slots in columns formed in the cavity. The slots are adapted to receive the terminal ends of concrete panels. Bulkheads may be removably installed into the cavity to vary a dimension of the concrete columns formed therein.
