Patent number: 8186906Abstract: A screed machine is formed with a forwardly positioned screed assembly including a wedge portion and pivoted wing members. The frame is supported on two rollers spaced behind the screed assembly, which is mounted on a mast for vertical movement in conjunction with a laser receiver that provides a signal from a laser level indicating the final desired grade of the stone base. The machine can be turned at a corner by extension of a jack stand to elevate the machine for rotation about the axis defined by the centrally located jack stand so that the screed machine can be redirected into a different direction without disturbing the final grade of the stone base. The screed machine is manually moved along the stone base by an operator pulling on the handle pivotally connected to the frame. A sight line provides a monitor for the lateral orientation of the screed assembly.Type: GrantFiled: June 4, 2010Date of Patent: May 29, 2012Assignee: SWA Holding Company, Inc.Inventor: Melvin M. Zimmerman

Patent number: 7980843Abstract: A concrete dispensing apparatus is used in a manufacturing process for producing pre-cast concrete structures, which are conventionally used to form a foundation for a residential or commercial building. The dispensing apparatus includes a hopper that funnels to a discharge opening extending along the entire transverse length of the dispensing apparatus. A plurality of individually controlled gates cover the entire discharge opening for selectively controlling the length and location of the discharge opening through which concrete is dispensed. The dispensing apparatus also includes a finishing mechanism including a vibratory screed and a rotational finishing roller. The form can be moved relative to the dispensing apparatus or vice versa. A form vibrator induces a vibratory motion into the form to remove air from the dispensed concrete mixture.Type: GrantFiled: August 22, 2006Date of Patent: July 19, 2011Assignee: SWA Holding Company, Inc.Inventors: Melvin M. Zimmerman, Carl S. Martin, Matthew S. Hildebrand

Patent number: 7736048Abstract: A segmented auger mechanism is mounted in the hopper of a concrete dispensing apparatus used to distribute a hydrated concrete mixture into a horizontally disposed form to manufacture pre-cast concrete structures, such as concrete wall panels used to form a foundation for a residential or commercial building. The auger mechanism is formed of connected segments that can be individually and independently removed from the concrete structure for service and repair. The auger is rotatably supported by a pair of end bearings supported on the opposing end walls of the hopper of the dispensing apparatus, and by at least one interior bearing rotatably supporting a jack shaft having opposing half-round connecting portions for attachment to a corresponding connecting portion on the auger shaft. Removal of a segment of the auger mechanism facilitates the removal of the entire auger mechanism to minimize the down time of the concrete dispensing apparatus.Type: GrantFiled: August 22, 2006Date of Patent: June 15, 2010Assignee: SWA Holding Company, Inc.Inventors: Melvin M. Zimmerman, Carl S. Martin, Matthew S. Hildebrand

Patent number: 7530203Abstract: A pre-cast concrete wall system that incorporates a truss ledge for positioning a building floor system at a below-grade location. The truss ledge is defined by a vertical wall formed as a continuation of the exterior wall of the wall panel extending from the footer beam to the upper bond beam and projecting vertically above the upper bond beam to provide a support surface for the building floor members. A floor truss system can be supported on the upper bond beam with the truss ledge forming a concrete below-grade surface externally of the floor trusses. Galvanized steel stud facings incorporating fold-up reinforcing bar supports are used on the interior surface of the vertical wall beams. Insulated access holes are formed through the vertical beams for the passage of wiring and plumbing behind the wall finish to be fastened to the stud facings.Type: GrantFiled: November 5, 2004Date of Patent: May 12, 2009Assignee: SWA Holding Company, Inc.Inventors: Robert W. Hare, Melvin M. Zimmerman

Patent number: 6494004Abstract: The disclosure is for a method and apparatus for constructing a concrete wall with a single pouring of concrete. The mold for the pouring of the wall is formed essentially of plastic foam insulation which remains attached to the finished wall to serve as thermal insulation. The wall structure is therefore self jigging and requires no elaborate mold structure or any time or labor to remove the finished wall from the mold.Type: GrantFiled: April 30, 2001Date of Patent: December 17, 2002Assignee: SWA Holding Company, Inc.Inventor: Melvin M. Zimmerman

Patent number: 5656194Abstract: The apparatus is an assembly jig for constructing prefabricated concrete wall sections. Two parallel elongated "L" cross section members, each with an outer vertical wall, are connected to a base structure with pivots, and several separated sections of inner vertical walls are attached by pivots at the edge of the base of each "L" to form parallel channel molds with spaces in the inner walls to receive prefabricated concrete studs. The wall is constructed by placing concrete studs and insulation sheets between the channels, and pouring concrete into the channel molds and over the studs and insulation sheets. The "L" members are pivoted down to release the hardened concrete beam which has been formed within each mold and thereby facilitate removal of the finished wall section from the assembly jig.Type: GrantFiled: June 14, 1995Date of Patent: August 12, 1997Assignee: Superior Walls of America, Ltd.Inventor: Melvin M. Zimmerman

Patent number: 5055252Abstract: A method of constructing a wall by casting concrete within a horizontal frame which surrounds "U" shaped stud forms, which will determine vertical studs, and support members, which will determine top and bottom horizontal members. Before filling the frame with concrete the spaces between the stud forms and the support members are filled with insulating panels which are supported on the edges of the stud molds. Also before pouring the concrete, reinforcing rods may be placed in the stud molds and support members, and the reinforcing rods connected together to form an integrated reinforcing structure.Type: GrantFiled: April 23, 1990Date of Patent: October 8, 1991Assignee: Superior Walls of America, Ltd.Inventor: Melvin M. Zimmerman

Patent number: 4934121Abstract: A prefabricated concrete wall structure with an integrated, interconnected reinforcing structure within its various structural members. Each vertical stud and horizontal beam is formed with at least one reinforcing rod within it, and each reinforcing rod is connected to the reinforcing rods in abutting members. The wall section attachment fixture is also connected to the reinforcing rod in the structural member in which it is housed so that the integration of reinforcement is continued from section to section as the attachment fixtures are bolted together.Type: GrantFiled: January 12, 1989Date of Patent: June 19, 1990Assignee: Superior Walls of America, Ltd.Inventor: Melvin M. Zimmerman

Patent number: 4751803Abstract: A new method of construction for concrete wall structures. Precast concrete studs with fasteners protruding from one edge are used to build the framework of the walls while oriented in a horizontal plane, rigid sheet insulation is attached to the outside of the concrete studs, and wire mesh is laid upon the sheet insulation. Concrete is then poured onto the insulation, the wire and the protruding fasteners to form a continuous waterproof outer surface. New top and bottom beams which are bonded to the concrete studs are formed at the same time as the outer concrete surface. After setting of the concrete, the wall is one integral concrete structure which may be transported to a construction site for erection.Type: GrantFiled: April 21, 1986Date of Patent: June 21, 1988Assignee: Superior Walls of America, Ltd.Inventor: Melvin M. Zimmerman
