Abstract
Abstract Wall panels are formed with horizontal edge faces. An edge portion integral with the panel projects from one of these edge faces. Another edge portion is recessed into the opposite edge face and is shaped to fit the projecting edge portion of another panel. A groove extends into each projecting and recessed edge portion to form a pair of grooves facing one another between the edge portions of successive panels. Sealing material, substantially filling the pair of grooves, completes the wall structures.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
203 words
Wall structure comprising a plurality of generally planar wall panels, each panel having a pair of edge faces opposite and parallel to one another and a pair of vertical edges, at least one vertical edge of a respective panel being spaced from the vertical edge of a successive panel; an edge portion integral with the panel and projecting from one of said edge faces, generally in the plane of the panel; another edge portion recessed into the opposite edge face and fitting the projecting edge portion of a successive panel; a relatively narrow groove extending into each of said edge portions intermediate the lateral sides thereof, the grooves in the edge portions of successive panels facing one another, at least some of said panels having recesses in side surface portions thereof between said edge faces and adapted to permit the insertion of scaffold means during the erection of the wall structure; sealing material in the facing grooves; and vertical concrete pillar structures each located in the space bounded by the respective vertical edges of successive panels, including relatively thin concrete plates spanning said space and constituting inner surface portions of the wall structure, said plates being both thinner and narrower than said panels.
Claim 2
Dependent Claim
203 words
Wall structure comprising a plurality of generally planar wall panels, each panel having a pair of edge faces opposite and parallel to one another and a pair of vertical edges, at least one vertical edge of a respective panel being spaced from the vertical edge of a successive panel; an edge portion integral with the panel and projecting from one of said edge faces, generally in the plane of the panel; another edge portion recessed into the opposite edge face and fitting the projecting edge portion of a successive panel; a relatively narrow groove extending into each of said edge portions intermediate the lateral sides thereof, the grooves in the edge portions of successive panels facing one another, at least some of said panels having recesses in side surface portions thereof between said edge faces and adapted to permit the insertion of scaffold means during the erection of the wall structure; sealing material in the facing grooves; and vertical concrete pillar structures each located in the space bounded by the respective vertical edges of successive panels, including relatively thin concrete plates spanning said space and constituting inner surface portions of the wall structure, said plates being both thinner and narrower than said panels.
Claim 3
Dependent Claim
14 words
Wall structure as defined in claim 1, wherein said panels substantially consist of concrete.
Claim 4
Dependent Claim
15 words
Wall structure as defined in claim 2, wherein said sealing material substantially consists of concrete.
Claim 5
Dependent Claim
14 words
Wall structure as defined in claim 1, wherein said edge faces are arranged horizontally.
Claim 6
Dependent Claim
26 words
Wall structure as defined in claim 4, wherein said edge faces with said edge portions projecting therefrom are arranged as upper edge faces of each panel.
Claim 7
Dependent Claim
22 words
Wall structure as defined in claim 4, wherein said edge portions and grooves are centered between the side surfaces of each panel.
Claim 8
Dependent Claim
47 words
Wall structure as defined in claim 6, also including metallic rod means cast into each panel, said rod means extending into said facing grooves and back therefrom into the panel, to provide handle means for holding and transporting the panel during the construction of the wall structure.
Claim 9
Dependent Claim
30 words
Wall structure as defined in claim 1, wherein each of said panels has at least one elongated aperture extending through the same, parallel to said edge faces and spaced therefrom.
Claim 10
Dependent Claim
27 words
Wall structure as defined in claim 8, wherein said aperture consists of two frusto-conical recesses, each extending from a vertical edge of the panel into the panel.
Claim 11
Dependent Claim
47 words
Wall structure as defined in claim 1, particularly for a silo, wherein said plates are arranged to provide inner surface portions of the silo, at least some of said additional panels having recesses in surface portions thereof to allow insertion of steps for access to the silo.
