Abstract
Abstract Legs of modular components of building structures, in the form of hollow columns of rectangular cross-section, are anchored to a base by having their lower ends received in sockets rising from that base. Within each socket, which may be designed to accommodate one or more columns, two pyramidal spreaders with oppositely sloping surfaces are coaxially disposed above and below a median plane within each column end and are positively engaged, via dovetail couplings, with respective sets of wedgeshaped shoes contacting their outer surfaces; a turnbuckle-type leadscrew, passing axially through these spreaders, engages them with two oppositely threaded stem portions to move them toward or away from each other while the shoes are held by tension springs against an interposed annular spacer. Rotation of the turnbuckle in a predetermined direction thus moves the shoes apart and against the column walls upon which they bear via narrow ribs, thereby clamping the column in position within the socket.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
An anchorage for a leg of a building structure, said leg having a lower end in the form of a hollow prism with deformable walls, comprising: a mounting plate for supporting said leg; an upwardly open prismatic socket for said leg rising from said mounting plate and rigid therewith; turnbuckle means journaled in said mounting plate and extending vertically into said socket, said turnbuckle means having oppositely threaded upper and lower portions on a common stem; wedge-shaped upper and lower spreaders with inversely converging outer faces threadedly engaged by said upper and lower portions, respectively, for relative displacement by said turnbuckle means upon rotation of said stem; and upper and lower pressure members positively guided on oppositely sloping outer faces of said upper and lower spreaders, respectively, and received in said leg together with said spreaders and said oppositely threaded portions for radially outward camming against adjoining walls of said leg upon rotation of said stem in a predetermined sense, thereby firmly clamping said leg in said socket, said turnbuckle means being accessible from without for performing such rotation.
Claim 2
Dependent Claim
179 words
An anchorage for a leg of a building structure, said leg having a lower end in the form of a hollow prism with deformable walls, comprising: a mounting plate for supporting said leg; an upwardly open prismatic socket for said leg rising from said mounting plate and rigid therewith; turnbuckle means journaled in said mounting plate and extending vertically into said socket, said turnbuckle means having oppositely threaded upper and lower portions on a common stem; wedge-shaped upper and lower spreaders with inversely converging outer faces threadedly engaged by said upper and lower portions, respectively, for relative displacement by said turnbuckle means upon rotation of said stem; and upper and lower pressure members positively guided on oppositely sloping outer faces of said upper and lower spreaders, respectively, and received in said leg together with said spreaders and said oppositely threaded portions for radially outward camming against adjoining walls of said leg upon rotation of said stem in a predetermined sense, thereby firmly clamping said leg in said socket, said turnbuckle means being accessible from without for performing such rotation.
Claim 3
Dependent Claim
23 words
An anchorage as defined in claim 1 wherein said pressure members and said spreaders are provided with dovetailing formations along contacting surfaces thereof.
Claim 4
Dependent Claim
35 words
An anchorage as defined in claim 2 wherein said upper and lower spreaders converge toward a common midplane, further comprising biasing means tending to draw said pressure members toward said midplane along said contacting surfaces.
Claim 5
Dependent Claim
22 words
An anchorage as defined in claim 3, further comprising spacer means interposed between said pressure members in the region of said midplane.
Claim 6
Dependent Claim
29 words
An anchorage as defined in claim 2 wherein said pressure members are provided with narrow outer projections bearing on said adjoining walls upon an outward camming by said spreaders.
Claim 7
Dependent Claim
46 words
An anchorage as defined in claim 1 wherein said leg is a four-sided column, said turnbuckle means comprising a leaDscrew extending axially within said column, said spreaders having the shape of four-sided pyramids, said pressure members forming two four-member sets contacting respective faces of said pyramids.
Claim 8
Dependent Claim
60 words
An anchorage as defined in claim 1 wherein said leg consists of a plurality of closely juxtaposed four-sided columns, said turnbuckle means comprising a leadscrew extending axially within each column, said spreaders having the shape of a pair of four-sided pyramids on each leadscrew, said pressure members forming within each column two four-member sets contacting respective faces of said pyramids.
Claim 9
Dependent Claim
18 words
An anchorage as defined in claim 7, further comprising compressible means inserted between adjoining columns within said socket.
Claim 10
Dependent Claim
37 words
An anchorage as defined in claim 1, further comprising a supporting base for said mounting plate provided with an access opening, said turnbuckle means extending into said base for engagement by a tool via said access opening.
Claim 11
Dependent Claim
19 words
An anchorage as defined in claim 9 wherein said stem terminates in a polygonal head within said access opening.
