ABSTRACT:
A portable concrete molding apparatus for forming concrete structures of a predetermined configuration, either on-site or at a central manufacturing facility. The apparatus includes a trailer having furnace plenum bounded by a pair of fixed walls. Each fixed wall cooperates with a movable wall for forming a mold therebetween. Each movable wall includes a concrete inlet for introducing concrete into the bottom portion of the mold. The fixed and movable walls include push-off valves for ensuring separation of a concrete structure from the mold walls, as the mold walls are separated.
