Patent number: 6532710Abstract: This invention is a building technique with multiple applications that addresses many known needs in a vast marketplace that far surpasses existing technology. Energy savings alone is an extremely important worldwide issue that has not been addressed by other building techniques today, as it should have been. Today, Americans are dependent upon the radical and unstable oil producing nations for our energy. This trend is unwise and extremely dangerous to the peace of our nation. Measures must be taken now to slow down the depletion of natural energy resources. This process is a cutting edge, innovative technological building system that produces the highest energy efficiency in addition to fire protection, termite protection, moisture protection, sound resistance and wind resistance possible at a cost comparable to wood, block or steel construction.Type: GrantFiled: February 2, 2001Date of Patent: March 18, 2003Inventor: Leonard R.

Patent number: 4312163Abstract: An improved reinforced structural member and method of fabricating the member. The structural member is a truss slab of a type embodying a lower concrete slab having reinforcement embedded therein; means providing a network of passages overlying the base slab; and an overlying concrete slab with reinforcement therein, including concrete columns extending between the overlying slab and the base slab. Additional reinforcing members or struts are provided connected between the reinforcing members in the lower slab and the reinforcing members in the upper slab. These members are of improved construction embodying a lower section and a separable upper section. The lower section extends to the height of the top surface of the lower slab permitting improvements in the method in that the lower slab can be poured without the reinforcing struts or members being in the way. The upper section of the reinforcing strut is then joined to the lower section, after which the upper slab is poured.Type: GrantFiled: August 27, 1979Date of Patent: January 26, 1982Assignee: Aircontrol Systems, Inc.Inventor: John C. Leemhuis

Patent number: 4259820Abstract: A heat-insulating, antisweat structural component for prefabricated residential houses, etc. comprises a set of H-shaped steel sheet piles each having opposed side plates coupled by a coupling plate and fittingly coupled to the other in a side-by-side relationship. In each H-shaped steel sheet pile, an engaging piece is formed at one edge and a fitting piece adapted to snugly fit the engaging piece is formed at the other edge of each of the side plates in such a manner that they are continuous along the respective edges, and fitting grooves are formed centrally on the opposed surfaces of the coupling plate to extend in an opposed relationship to each other and in parallel with the side plates.Type: GrantFiled: July 31, 1979Date of Patent: April 7, 1981Inventors: Takeichi Kita, Takuji Kita

Patent number: 4157638Abstract: A building structure and a method of constructing a wall utilizing the building structure, for the construction of concrete buildings in a simplified manner. Each building structure unit includes a pair of exterior panels of cardboard sandwiching an insulating foam panel, or sandwiching two foam panels which in turn sandwich another cardboard panel. The various panels are glued together, and tabs extend from the exterior panels along the bottom of the structure, and along one side of the structure. A number of the structures are stood in place so that they extend vertically, with the tab portions along their bottoms attached to the building base, and the structures all arranged side by side in interlocking engagement to provide a continuous self-supporting wall structure providing a horizontally impenetrable barrier.Type: GrantFiled: October 3, 1977Date of Patent: June 12, 1979Assignee: Thermo-Core Building Systems, Inc.Inventor: Alphonse Della-Donna

Patent number: 4149349Abstract: A prefabricated consumable assembly for forming a concrete wall structure includes a pair of spaced apart side plates interconnected on their ends by transverse tie members. A single or a pair of insulating panels is positioned within the side plates and structure is associated with each tie member which defines grooves for receiving and holding the side edges of the insulating panel or panels. The groove defining structure may be formed by a detachable clip mounted on the tie members or entirely or in part integral with the tie members. Mechanism is provided for interlocking assembled ones of the prefabricated assemblies to form a wall structure including an inside corner. The side plates may be arranged for bending to form corners.Type: GrantFiled: October 24, 1972Date of Patent: April 17, 1979Assignee: Arcadia Enterprises Corp.Inventors: Knut E. Nilsen, Homer C. Shirley

Patent number: 3999341Abstract: An architecturally finished concrete structure is a composite of a finished wallboard member, such as plasterboard, plywood, etc., to which is bonded a plurality of elongated hollow void creating devices, with said devices being embedded in a concrete structure that is adhered to said finished wallboard member. In the subject method, one side, or both sides, of the concrete form for casting-in-place the concrete structure is defined by a finished wallboard member to which is adhered a plurality of elongated hollow void creating devices. Concrete is poured in the space defined by the concrete form, and is cured so as to be in intimate contact with, and embed, the void creating devices, and the resulting concrete structure is architecturally finished by having one or both faces thereof formed of said wallboard member.Type: GrantFiled: September 29, 1975Date of Patent: December 28, 1976Inventor: Robert K. Stout

Patent number: 3982368Abstract: A wall, such as a load bearing wall, and method for forming same. The wall comprises a core member having a substantial void therein and reticulated sheets of reinforcing material positioned on both sides of the core and spaced therefrom. The wall is formed as by spraying cementitious material through and around the sheet material thus to produce a composite wall comprising first and second panels of reinforced cementitious material in spaced relation, having a hollow core therebetween, said panels being joined together as a unitary structural member.Type: GrantFiled: December 18, 1974Date of Patent: September 28, 1976Assignee: American Volkscastle International Inc.Inventor: Arthur Perrin
