Abstract
A prefabricated building unit has a framed inner stud wall to which is joined an intermediate wall of insulation board and an exterior wall of concrete, the concrete being poured on the intermediate wall and over angled, protruding nails that fasten the intermediate wall to the stud wall. A plurality of the building units are combined to complete the walls of a structure, the method of joining being to weld together reinforcing bars extending from the concrete portion of each unit and then to pour a pilaster over the joined reinforcing bar. The exterior of the concrete wall is finished during prefabrication with exposed aggregate and exterior varnish.
Claims1
The method of constructing a prefabricated building unit for use with similar adjacent units, comprising:
- a. framing a stud wall against a flat horizontal surface,
- b. nailing a coating of intermediate wall on one side of said stud wall, allowing the nail heads to protrude a substantial distance from the intermediate wall,
- c. placing a frame for concrete on top of the intermediate wall,
- d. placing horizontal reinforcing bars in the frame with the ends of the bars extending through holes in the sides of the frame for joining units,
- e. pouring a concrete outer wall in the frame while the stud wall remains against the flat horizontal surface, the concrete holding the stud wall in a flat plane and preventing warpage of the studs,
- f. washing the concrete to produce an exposed aggregate finish, and
- g. raising the wall to vertical position for installation with said similar units at a building site.
