Abstract
Abstract A joint for constituting a node of three-dimensional spatial framed structures comprises a convex polyhedral base plate from which angularly spaced pairs of wings extend outwardly, each pair forming a gap in which the flattened end of a longitudinal element of the framed structure is adapted to be inserted. The wings are secured either to the solid angles of intersection between the faces of the base plate or along the center lines of the faces thereof. Holes are provided through the wings and faces, and also through the flattened ends of the elements, for bolting the joint to the elements and to diagonal elements to form superposed flat assemblies interconnected in turn by the diagonal elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
197 words
A joint for use in forming a three-dimensional framed structure of the type including plural superposed and parallelly spaced planar assemblies, each said planar assembly being formed of plural of the joints connected by planar longitudinal elements extending in the plane of the assembly, and diagonal longitudinal elements extending between and connecting the joints of adjacent of the planar assemblies, said joint comprising: a base member having a regular convex polyhedral-shaped surface formed by a plurality of faces which are inclined with respect to each other and which are joined at solid lines of intersection which converge at a vertex of said surface; a plurality of lugs integral with and extending outwardly from said surface of said base member, each said lug extending substantially in a plane containing an axis of said base member which extends through said vertex of said surface; said lugs including means for connection to planar longitudinal elements to join a plurality of the joints to form a planar assembly; and at least a portion of said faces of said surface of said base member including means for connection to diagonal longitudinal elements to join joints of and extend between adjacent planar assemblies.
Claim 2
Dependent Claim
197 words
A joint for use in forming a three-dimensional framed structure of the type including plural superposed and parallelly spaced planar assemblies, each said planar assembly being formed of plural of the joints connected by planar longitudinal elements extending in the plane of the assembly, and diagonal longitudinal elements extending between and connecting the joints of adjacent of the planar assemblies, said joint comprising: a base member having a regular convex polyhedral-shaped surface formed by a plurality of faces which are inclined with respect to each other and which are joined at solid lines of intersection which converge at a vertex of said surface; a plurality of lugs integral with and extending outwardly from said surface of said base member, each said lug extending substantially in a plane containing an axis of said base member which extends through said vertex of said surface; said lugs including means for connection to planar longitudinal elements to join a plurality of the joints to form a planar assembly; and at least a portion of said faces of said surface of said base member including means for connection to diagonal longitudinal elements to join joints of and extend between adjacent planar assemblies.
Claim 3
Dependent Claim
21 words
