  • Patent number: 8677716
    Abstract: A framing member incorporates a series of web slots along a portion of the member that are expanded through the process of manufacture. The expansion of the web slots creates voids and metal web elements in the webbed portion of the member, which can be a stud. The voids created during the expansion process can become the voids for running wiring, plumbing and heating ducts. The web elements can be designed to minimize thermal transmission from the exterior to the interior of a wall including the member, as well as provide adequate structure properties required from the structural member. The expanded slots allow the part to enlarge without increasing the amount of raw material and therefore substantially reducing the cost to manufacture.

  • Patent number: 8176635
    Abstract: Methods and systems to manufacture lattice-based sandwich structures from monolithic material. Such methods and systems eliminate the bonding process which is conventionally used to join lattice based truss cores to facesheets to form sandwich structures. This bonded interface is a key mode of failure for sandwich structures which are subjected to shear or bending loads because the nodes transfer forces from the face sheets to the core members while the topology for a given core relative density dictates the load carrying capacity (assuming adequate node-bond strength exists). An aspect comprises a core and related structures that provide very low density, good crush resistance and high in-plane shear resistance. An aspect of the truss structures may include sandwich panel cores and lattice truss topology that may be designed to efficiently support panel bending loads while maintaining an open topology that facilitates multifunctional applications.

  • Patent number: 7669379
    Abstract: A metal truss system comprising a pair of chord members of generally U-shaped cross-sectional configuration is joined together by a web formed of a single continuous piece having a wave shape. The apexes of the web are adapted to be received in each chord. The legs of the chords have inwardly recessed portions to form a narrowed throat portion, which provides a stop against which the apex of the web abuts. The resulting positioning of the web apex presents a maximum surface area for welding the web to the chord member. This enables an optimum amount of welding, while minimizing the weakening of the metal being welded. The configuration of the chords and web permits rapid fabrication of the truss.

  • Publication number: 20090272051
    Abstract: The present invention relates to a system for constructing temporary prefabricated structures for the motion picture, television and stage play industries. The invention uses interchangeable panels with an array of connecting elements for constructing walls, roofs and floors. Because of this nature of interchangeability, flexibility in the use of our panels affords last minute changes in set design to accommodate desirable camera or actor movements. The materials used are substantially strong enough to withstand transportation, use in adverse weather conditions, and storage for reuse, and are recyclable when life expectancy is reached. The system does not require site preparation prior to assembling structures. Buildings can be erected on virtually any surface and over existing vegetation with out destruction. More particularly, the components used to erect the structure are easy to assemble and disassemble and do not require the use of any fasteners or tools or heavy construction equipment.

  • Patent number: 7159365
    Abstract: In a system for making walls, at least two pairs of connector plates are provided, each including receptacle for receiving an end of a structural member. At least one spacer plate is located between and rotatably coupled to successively positioned connector plates. To form a wall, a pair of connector plates is coupled via the retaining means, one to each of a pair of generally opposing ends defined by structural members. The connector plates are rotatably movable relative to the spacer plates thereby allowing the structural members to be oriented relative to one another so as to form a surface having desired contours.
