An example buckling restrained brace (“BRB”) includes a casing exhibiting a hollow cross-sectional shape defining an interior region. The BRB also includes a core and at least a portion of the core is disposed in the interior region of the casing. For example, the casing may exhibit a first length and the core may exhibit a second length that is greater than the first length such that a portion of the core extends from the casing. The core is separated from the casing by an minimum gap distance along at least a portion of the first length of the casing and a corresponding portion of the second length of the core.

A composite lattice beam. The composite lattice beam includes four or more longitudinals. The four or more longitudinals are parallel to one another, comprise the four corners of a rectangle and include a tow, where the tow includes a bundle of untwisted fibers. The composite lattice beam also includes one or more outer diagonals. The one or more outer diagonals vary in two dimensions and include a tow, where the tow includes a bundle of untwisted fibers. The composite lattice beam further includes one or more inner diagonals. The one or more inner diagonals vary in three dimensions and include a tow, where the tow includes a bundle of untwisted fibers. The composite lattice beam additionally includes one or more nodes. The nodes are each an interweaving of at least one of the four or more longitudinals, at least one of the one or more outer diagonals and at least one of the one or more inner diagonals.

The present invention is a support structure including elongate hollow cylinder and flat plates secured thereto. A first rigid flat plate is horizontally disposed in overlying relation to each hollow cylinder and a second rigid flat plate is horizontally disposed in underlying relation to each hollow cylinder. Stress-distributing strengthening members are circumferentially positioned about the hollow cylinder and secured to their associated rigid flat plates. A key may extend from a first end of each hollow cylinder and a mating socket may be formed in a second end of each hollow cylinder to facilitate end-to-end interconnection of a plurality of hollow cylinders.

An elongate structure for supporting heavy loads includes an elongate hollow cylinder having a longitudinal axis of symmetry. Stress-distributing strengthening members are circumferentially positioned about and secured to the hollow cylinder in parallel relation to the longitudinal axis of symmetry. A first flat plate is disposed in overlying relation to the hollow cylinder and to the first, upper pair of strengthening members and a second flat plate is disposed in underlying relation to the hollow cylinder and to the second, lower pair of strengthening members. The second flat plate is disposed in a horizontal plane in parallel and diametrically opposed relation to the first flat plate. A key extends from a first end of the hollow cylinder and a mating socket is formed in a second end of the hollow cylinder to facilitate end-to-end interconnection of a plurality of the hollow cylinders.
摘要:
Multifunctional modular mother-beam built in structural steel or similar light, sturdy material, with a “U” configuration and provided with holes along its entire length, either on the back side, on the flanks, or on the edges, by which said mother-beams connect to one another either through their back sides, their flanks, or their edges, at any angle. They are fastened with screws inserted into said holes, with no need for welding. The flanks and edges are bended to facilitate fitting and fastening of the mother-beams. Mother-beams may connect by overlapping their back sides, by joining their edges, by joining their flanks, by joining flanks with edges, edges or flanks with the back side, through direct or reversed connection. It can act as a beam, pillar, trussed beam or bar, being especially useful in the construction of large areas, such as pavilions or similar constructions.

A conduit clamp for securing a conduit component to channel framing includes first and second jaws each having opposite first and second end portions. The first end portions of the first and second jaws are configured for securement to one another, such that first and second jaws generally oppose one another and the second end portions of the first and second jaws are free from attachment to one another, to define a conduit receiving space between the first and second jaws. Each of the first and second jaws includes a coupling component at the second end portion thereof having a generally dovetail shape configured for reception in an external fitting groove of the channel framing to attach the conduit clamp to the channel framing.
摘要:
A framework system for buildings and other structures having a plurality of structural columns each having a wall structure of generally circular cross-sectional configuration defining an internal chamber and having a number of pairs of elongate external undercut grooves extending the length of the column and defining internal elongate grooves also extending the length of the column. Structural framework members extend between adjacent ones of the structural columns and define opposed ends. Gripper members are mounted to the ends of each of the structural framework members and each have a pair of spaced hook-like lateral retainer flanges disposed in retaining engagement within the elongate external undercut grooves. A structural member extends the length of the internal chamber and has radially oriented structural flanges each being received within one of the internal elongate grooves.
摘要:
A system and method of manufacture providing reinforced structurally functional load-bearing members, including but not limited to using thermoplastic materials, such as High Density Polyethylene (HDPE), reinforced such as with an aluminum alloy or carbon fiber core element. Among its possible uses, the present invention has application for provision of structural support members, such as an illustrative I-joist product having a vertical center member preferably comprising HDPE, and top and bottom flanges having structurally meaningful reinforcement. The center member and flanges preferably comprising HDPE provides a relatively hard, durable, substantially weather-resistant structure.
摘要:
A hollow section, in particular for a lattice tower, including a first section part and a second section part, wherein the cross-section of the hollow section is formed such that the first section part includes two legs and the second section part is arranged between the legs of the first section part such that, in order to form a closed hollow cross-section, one of the end edges of the second section part is connected to one of the legs and the other end edge of the second section part is connected to the other leg of the first section part such that a partial segment of the particular leg of the first section part projects beyond the connection site.
摘要:
A tube with an external channel of a complex geometry. The channel does not distort or collapse when the tube is bent 90 degrees with a 4-inch radius. Fabric may be inserted into and securely held in the external channel. The tube is suitable for constructing frames of fabric structures, such as dodgers and biminis for boats, tents, chairs, etc.
