Abstract
Abstract A building skeleton, rising from a foundation, comprises columns of hexagonal profile with outwardly radiating vertical ribs extending from the corners of the hexagon, these columns being interconnected by beams detachably bolted to certain of their ribs. The foot of each column, anchored to the foundation by straps partly imbedded therein, abuts an end of a horizontal locating profile resting on the foundation which may also support a window pane, or wall paneling along with intermediate posts, in the space between two columns; the bottom plate of the profile terminates in an outwardly sloping shelf for the run-off precipitation. The beams at the top of the columns are in the form of C-channels disposed in back-to-back pairs, their flanges carrying a roof structure while the lower flanges of the inner beams support slabs of a false ceiling.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
A prefabricated building structure comprising: a plurality of spaced-apart columns rising from a foundation, said columns having a polygonal cross-section with vertical ribs radiating from the corners of the polygon; a set of beams interconnecting said columns at an elevated level, said beams being detachably joined to certain of said ribs; anchor means securing the foot of each column to said foundation; elongated locating members resting on said foundation between adjoining columns in abutting relationship with a rib of each column at the foot thereof; and a wall-supporting post rising from a locating member to the underside of an overlying beam, said post consisting of two spacedly nested upright channel members of relatively inverted U-shape having the intervening space filled with thermal insulation.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
A structure as defined in claim 1 wherein said members form downward-sloping shelves outside said wall means.
Claim 4
Dependent Claim
23 words
A structure as defined in claim 2 wherein said members are profiles of flattened tubular shape including bottom plates integral with said shelves.
Claim 5
Dependent Claim
40 words
A structure as defined in claim 3 wherein said members are cut away above said bottom plates, at angles corresponding to the inclination of abutting column ribs to their longitudinal dimensions, to form a contact edge for said abutting ribs.
Claim 6
Dependent Claim
32 words
A structure as defined in claim 4 wherein one of said channel members is provided along its back with a flat extension rising above said post into engagement with said overlying beam.
Claim 7
Dependent Claim
37 words
A structure as defined in claim 5 wherein said overlying beam is one of a pair of parallel beams bracketing a column rib coplanar with said extension, the latter terminating in a gap between said parallel beams.
Claim 8
Dependent Claim
27 words
A structure as defined in claim 6 wherein said anchor means comprises strap means partly imbedded in said foundation and extending into the space between adjoining ribs.
Claim 9
Dependent Claim
28 words
A structure as defined in claim 7 wherein said strap means comprises a pair of straps respectively attached to a pair of diametrically opposite ribs of the column.
Claim 10
Dependent Claim
30 words
A structure as defined in claim 7 wherein said anchor means further comprises a foot plate supporting the column, said strap means passing into the foundation alongside said foot plate.
Claim 11
Dependent Claim
114 words
A prefabricated building structure comprising: a plurality of spaced-apart columns rising from a foundation, said columns having a polygonal cross-section with vertical ribs radiating from the corners of the polygon, at least one of said columns being provided with a connector disposed in the space between two diverging ribs thereof, said connector having a first shank secured to one of said diverging ribs and a second shank bisecting said space; a set of beams interconnecting said columns at an elevated level, said beams being arranged in parallel pairs with closely spaced webs bracketing certain of said ribs; and a further beam pair having closely spaced webs secured to opposite sides of said second shank.
Claim 12
Dependent Claim
114 words

Claim 13
Dependent Claim
64 words
A structure as defined in claim 10 wherein one of said diverging ribs is bracketed by paired beams connected thereto, said paired beams having flanges on their webs with beveled extremities extending into the spaces between adjoining ribs, one of the beams of said further pair having a flange foreshortened to give clearance to the beveled flange extremity of one of said paired beams.
