Abstract: Apparatus for molding a concrete panel having:A. an articulated concrete-pouring mechanism with pivotally inter-connected horizontal tubes, each containing a motor-driven feed screw;B. a mold frame pivoted on a vertically-fixed, horizontal axis to be turned from an upright position, which it occupies while being filled with wet concrete, to an inverted position;C. a bottom plate and core assembly in the mold frame mounted for limited, vertically guided movement downward in the mold frame when it is turned over;D. and a vertically-displaceable platform below the mold frame for receiving the concrete filling from the mold cavity when the concrete is stripped from the mold due to its own weight and the weight of the bottom plate and core moving down in the inverted mold frame.

Abstract: In a building, reinforced concrete wall panels are bolted to each other and to the floor and roof to provide the outer shell of the building. At the bolt holes in these wall panels a rigid reinforcing rod framework, which is cast in the concrete panel, provides at least one pair of rods passing respectively on opposite sides of each bolt hole to reinforce the panel there. Certain of the wall panels have window openings for receiving standard size, aluminum frame windows. Others of the wall panels provide doorway openings for receiving standard width doors. Preferably, at each outside corner of the building a special corner wall panel is provided.
