Abstract
Abstract A building-frame structure is assembled from prefabricated columns and girders or beams forming a horizontal grid, each of the columns being composed of two or more parallel uprights forming vertical channels therebetween to receive the webs of the beams. Profiled connectors, with ribs of the same width as the beams, can also be clamped between these uprights to secure the column to a wall consisting of one or more framed panels onto which the connector can be clipped.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A building-frame structure comprising vertical columns and horizontal beams spanning said columns at an elevated level, each column being formed with at least three outwardly open vertical channels radiating in different directions from the vicinity of a central axis and extending over the full height of the columns, said beams having webs of a height substantially less than that of the columns received in channels of the columns spanned thereby, and fastening means detachably securing said beams to said columns; the web of each beam being bounded by an upper flange and a lower flange and projecting endwise beyond said lower flange, the projecting end of the web occupying a top portion of a column channel with said upper flange overlying the top of the column.
Claim 2
Dependent Claim
126 words
A building-frame structure comprising vertical columns and horizontal beams spanning said columns at an elevated level, each column being formed with at least three outwardly open vertical channels radiating in different directions from the vicinity of a central axis and extending over the full height of the columns, said beams having webs of a height substantially less than that of the columns received in channels of the columns spanned thereby, and fastening means detachably securing said beams to said columns; the web of each beam being bounded by an upper flange and a lower flange and projecting endwise beyond said lower flange, the projecting end of the web occupying a top portion of a column channel with said upper flange overlying the top of the column.
Claim 3
Dependent Claim
23 words
A structure as defined in claim 2 wherein said uprights are profiles with pairs of outwardly extending ribs forming an additional channel therebetween.
Claim 4
Dependent Claim
29 words
A structure as defined in claim 3 wherein said profiles have cross-sections bent at an angle of 120*, said additional channel being centered on the bisector of said angle.
Claim 5
Dependent Claim
16 words
A structure as defined in claim 2 wherein said uprights are hollow posts of polygonal cross-section.
Claim 6
Dependent Claim
13 words
A structure as defined in claim 5 wherein said cross-section is substantIally square.
Claim 7
Dependent Claim
36 words
A structure as defined in claim 5 wherein confronting sides of adjoining posts are provided with bores for said fastening means and exposed sides of said posts are provided with holes giving access to said bores.
Claim 8
Dependent Claim
22 words
A structure as defined in claim 2 wherein said columns are provided with foot plates having upstanding flanges received in said channels.
Claim 9
Dependent Claim
32 words
A structure as defined in claim 1 wherein said upper flange has beveled corners facilitating insertion of an identical web at the same level into an adjoining channel of the same column.
