Abstract
Abstract A wall structure formed of pre-cast reinforced concrete building panels which are each supported and sealed along their bottom edge in a self-aligning groove or channel in a supporting structure and are interlocked and sealed with each other along their vertical butting edges. Bridging members extending along the top edge of the panels tie adjacent panels together. Integral stud members extend from the top edge for lifting and fastening purposes. Some of the panels may be furnished with window frames, door frames and electrical wiring and plumbing components that are integral therewith.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
146 words
A preformed structural wall including at least two modular sections disposed in edgewise butting relationship, each section having: a. a pre-cast reinforced concrete panel of generally rectangular shape with at least two integral reinforcing stud members extending upwardly from the top edge thereof; b. the vertical side edges of adjacent panels having mating surfaces forming an interlocking connection therebetween, and sealing means present in the connection for waterproffing the joint; c. the bottom edge of each panel being adapted to be seated in an elongated groove of a supporting member so as to align the panels, and sealing means present in the groove for waterproofing the joint and supporting the panel; d. an elongated bridging member that spans only two adjacent panels and is attached to both panels by means of the integral stud members, so as to be in abutment with an adjacent bridging member.
Claim 2
Dependent Claim
146 words
A preformed structural wall including at least two modular sections disposed in edgewise butting relationship, each section having: a. a pre-cast reinforced concrete panel of generally rectangular shape with at least two integral reinforcing stud members extending upwardly from the top edge thereof; b. the vertical side edges of adjacent panels having mating surfaces forming an interlocking connection therebetween, and sealing means present in the connection for waterproffing the joint; c. the bottom edge of each panel being adapted to be seated in an elongated groove of a supporting member so as to align the panels, and sealing means present in the groove for waterproofing the joint and supporting the panel; d. an elongated bridging member that spans only two adjacent panels and is attached to both panels by means of the integral stud members, so as to be in abutment with an adjacent bridging member.
Claim 3
Dependent Claim
35 words
The invention of claim 1 wherein each panel is furnished with a large U-shaped reinforcing rod which extends out of the top edge of the panel and terminates as the said two integral stud members.
Claim 4
Dependent Claim
42 words
The invention of claim 1 wherein the said elongated groove of a supporting member is formed by a channel beam, and the said bridging members are formed of inverted channel beams which fit down over the top edge of two adjacent panels.
Claim 5
Dependent Claim
16 words
The invention of claim 1 wherein the said mating surfaces are triangular tongue and V-groove members.
Claim 6
Dependent Claim
96 words
The invention of claim 1 wherein the said structural wall includes a corner formation with one of the beforementioned pre-cast panels and a special panel having a vertical mating surface along one side of one of its planar surfaces for engaging with the mating surface on the vertical side edge of the adjacent corner panel, and a corner bridging member of angular configuration assembled over the top edge of the two adjacent panels of the corner formation and engaging one of the integral stud members at each end of the bridging member for holding them together.
Claim 7
Dependent Claim
26 words
The invention of claim 5 wherein the said bridging members are formed of inverted channel beams which fit down over the top edge of the panels.
Claim 8
Dependent Claim
17 words
The invention of claim 5 wherein the said mating surfaces are triangular tongue and V groove members.
Claim 9
Dependent Claim
46 words
The invention of claim 5 wherein at least some of the said pre-cast panels are furnished with window frames and some with door frames, and some of the panels are furnished with electrical wiring components all of which are integral therewith before erection on the site.
Claim 10
Dependent Claim
113 words
The invention of claim 1, wherein the elongated groove of a supporting member is an absolutely level groove along a longitudinal plane formed in the concrete footing by the following steps: a. pouring a partial footing of concrete; b. installing vertically threaded rods into said partially poured footing; c. installing channel members over said threaded rods and in said partially set concrete of said partially poured footing; d. pouring the remainder of said footing around said channel member; e. leveling said channel member to an absolute level position in a horizontal plane by manipulation of nuts on said vertical threaded rods; and f. breaking off the vertical threaded rods level with said plane.
Claim 11
Dependent Claim
114 words
The process of forming a perfectly level and straight elongated groove in a continuous footing forming the support of pre-cast building members in a structural wall which includes the steps of: a. pouring a partial footing of concrete; b. installing vertical threaded rods in spaced relation in said concrete; c. installing channel members over said vertically threaded rods and into said partially set concrete footing; d. pouring the remainder of said footing around said channel member; e. leveling said channel member to a level position in a horizontal plane by manipulation of nuts on said vertically threaded rods; f. thereafter breaking off the vertical threaded rods level with the surface of said level plane.
Claim 12
Dependent Claim
114 words
The process of forming a perfectly level and straight elongated groove in a continuous footing forming the support of pre-cast building members in a structural wall which includes the steps of: a. pouring a partial footing of concrete; b. installing vertical threaded rods in spaced relation in said concrete; c. installing channel members over said vertically threaded rods and into said partially set concrete footing; d. pouring the remainder of said footing around said channel member; e. leveling said channel member to a level position in a horizontal plane by manipulation of nuts on said vertically threaded rods; f. thereafter breaking off the vertical threaded rods level with the surface of said level plane.
Claim 13
Dependent Claim
29 words
The invention of claims 9 or 10, the improvement which further comprises the step of removing said channel member before the poured concrete of said footing is absolutely set.
