40-86 BUILDING CONSTRUCTION Abstract of the Disclosure A concrete building is constructed by initi- ally forming a generally circular concrete pad. A spherical or slightly more than hemispherical plastic mold is then erected on the concrete pad with a central post extending axially out the central top of the mold. Barbed wire is then wrapped around the mold and wire mesh is subsequently wrapped around the mold on top of the barbed wire, with the barbed wire serving to space the reinforcing wire mesh away from the surface of the mold. Concrete is then applied to the outside of the mold starting at the bottom of the mold adjacent the concrete pad and moving helically up the surface of the mold while laying concrete around the mold in strips. The apparatus for applying the concrete includes a frame mounted on wheels and pivoted on the post extending out of the top of the mold and being curved to follow the exterior surface of the mold. Mounted on the frame is a hopper arrangement for feeding concrete against the mold and for automatically smoothing it into place on the outer surface of the mold with the barbed wire and the wire mesh concrete reinforcing being embedded in the two inch thick layer of concrete. A motor is provided for feeding the hopper and concrete dis- pensing and smoothing apparatus up the movable frame as the frame is rotated around the surface of the mold, to form the exterior of a concrete building.
