Abstract
A building construction system uses a mold set up at a construction site so that the external part of the mold is spaced clear of the internal part. Building elements including those which are functional in the construction operation are arranged around the internal mold part. Such functional elements include connecting rod anchorages around the lower region of the mold, and the like. The external mold part is moved into position near the internal mold part, and the mold is filled to form a casting. A lifting frame is arranged over the mold and adjustably connected to the connecting rods. Then the external mold part is moved away to release the casting, and the frame is lifted to raise the casting up over the mold for movement to a building site near the construction site. To facilitate release of the casting from the internal mold part, the internal mold portion is formed of outward facing walls that are supported so they are braced against inward motion from a lowermost position and are permitted to move inwardly as the walls are raised from the lowermost position. This affords clearance between the internal mold parts and the casting as the casting is lifted. The mold also has corner release means and the system may include release elements affixed to the building during casting.
