Abstract:
A structural frame unit for use in constructing a multi-unit building. The structural frame unit includes a plurality of connectors, beams, columns and cross bracings to define a load bearing, structurally stable three-dimensional structure. At least a subset of the components of a structurally stable three-dimensional structure define connectors configured to secure non-structural wall panels, utilities and exterior cladding relative to the structurally stable three-dimensional structure.
Abstract:
A nodal system (30) for a load-bearing structure(100), comprising connection sections (19,19′) of beams (10,10′), converging with each other towards a node (101) so as to form an interstitial space. The nodal system (30) also comprises a locking key (40) having an input configuration, wherein it is insertable in the interstitial space, and a locking configuration, rotated with respect to the input configuration, wherein it is suitable for making a mechanical connection between the connection sections (19,19′) of the beams (10,10′). The nodal system (30) also has retention means (18, 18′, 48, 108) for connecting the locking key (40) to, the connection sections (19,19′) of the beams (10,10′) so as to make them integral the one with the other.
Abstract:
A family of space frames formed from one or more parallel, planar layers, with each layer comprising a plurality of prismatic nodes arranged in a spaced, non-periodic or periodic, planar array and a plurality of struts coupling adjacent nodes together. Each node has top and bottom surfaces of the same configuration and p side surfaces interconnecting the top and bottom surfaces or any suitable shape derived from this configuration. P is any odd number greater than three or any even number greater than four. Adjacent layers are coupled via interconnecting struts that are perpendicular to each layer or tilted relative to each layer. Successive layers are the same or different. The space frames can also define, locate, and map out tiled surfaces or block-filled volumes.
Abstract:
A joint for joining structural members extending in at least two intersecting planes comprises a pair of outer spaced-apart annular plate members parallel to one of the intersecting planes and sandwiching structural members in that plane, a pair of spaced-apart inner plate members located within the outer plate members and parallel to another of the intersecting planes for sandwiching structural members in the another plane and attachment means for attaching the inner plate members and the outer plate members. The invention also extends to a structure incorporating the joint and modified forms of the joint are disclosed for use on the sides and corners of such a structure.
Abstract:
An automated assembly, maintenance, and repair system for the construction of a large space structure. The space structure comprises a plurality of trusses and truss junctions that in turn are made up of a plurality of individual struts and nodes. The truss assemblies are progressively built by an assembler trolley as the trolley crawls along the constructed truss. The trolley comprises a forward crawler and a rear crawler joined by an articulated coupler. The crawlers are carried along the structure by belt transports incorporating grippers that engage the truss structure at the nodes. Manipulator arms for strut and node assembly are located on the forward crawler, and the majority of control, power, and communication systems are located in the rear crawler. Cargo canisters filled with component parts for constructing the space structure are carried by the forward crawler. The space structure configuration is determined by the arrangement of the individual struts and nodes during the assembly process.

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.
Abstract:
A structural framing system and apparatus for use in the fabrication of a structural framework of selected geometric configuration of cast material, for example, concrete or plastic. The method and apparatus of the present invention includes a generally hollow hub form defined by a generally continuous shell of selected geometric form to provide a locus for radiating and outwardly extending frame member forms, which communicate with the hub form where a suitable hardenable material is provided to fill the hub form and the frame member forms to provide a self-supporting structural framework of interconnected hubs and frame members, the frame members extending divergently outwardly from the hub members. Structural reinforcements such as reinforcing steel can be attached within the hub to extend divergently outwardly through the frame form members.
Abstract:
The present invention is concerned with a rigid assembly joint for connecting at least one longitudinal tubular element of a framework structure to at least one traverse tubular element of the said structure.More particularly the present invention deals with a rigid assembly joint of two tubular longitudinal elements and at least one traverse tubular element of a framework structure which consists substantially of metallic tubes of generally circular cross section, an assembly joint in which the two longitudinal tubular elements are joined in an abutting relationship, while the traverse tubular element forms an angle with at least one of the longitudinal tubular elements.
Abstract:
A roof or ceiling structure for buildings in the nature of a "space frame" or three-dimensional truss, including substantially planar panels and supporting struts and a method for producing the structure on-site. The panels serve a dual purpose as structural members interconnecting the struts and as surface elements for a roof or ceiling. Two panels spaced parallel to one another are interconnected by equiangular struts to form an array of tetrahedrons throughout the three-dimensional structural member. Each panel is made up from sheet material, and the seams between panels are accommodated by rotating each layer of panels relative to those adjacent to it so that the seams overlap abutting sheet surfaces in differing angular attitudes.
