The present invention relates to a composite beam in which a fabricated truss is embedded in the concrete, and more particularly, it relates to a composite beam in which the fabricated truss acts as a truss beam which endures the concrete weight and the construction load in the liquid phase before the curing of the concrete and acts as a main structural member together with the concrete after the curing of the concrete.

In a joint structure of steel beam structure, a bracket is coupled and fixed to the lateral side of a large beam or a pillar and a steel beam is coupled to the bracket such that the steel beam is coupled to the lateral side of the large beam or the pillar. One end of the bracket is coupled to the lateral side of the large beam or the pillar, and the other end is inclined such that the lower part thereof forms an acute angle, wherein a first attachment plate is coupled to the inclined end part of the bracket such that a fixed length thereof protrudes from the upper end of the bracket. The lower part of one end of the steel beam is inclined at an obtuse angle so as to correspond to the other inclined end of the bracket.

The modular anti-ballistic shelter system includes two end units and, optionally, additional middle units for a wider structure. End and middle units may also stack atop each other for multi-story structures. Each unit is configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each exterior wall of each end unit and each middle unit is reinforced with wall studs that penetrate the unit's structural framework of beams and frames. Even though these wall studs are welded into place, penetration of the wall studs into the beams and frames ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

The disclosed technology provides a seismic yielding connector. The seismic yielding connector includes a U-shaped plate configured to connect a side stud of a panel to another component of a panel and a yielding plate located between the U-shaped plate and the side stud of the panel. A high-strength bolt connects the U-shaped plate, the yielding plate, and the side stud of the panel to a structural column. A bushing is located between the U-shaped plate and the structural column.

A splice having a main body and one or more protrusions extending from the main body. The one or more protrusions can be operable to interfere with a rail when the main body is installed into an opening of the rail. The one or more protrusions may be operable to cut into a coating of the rail and form an electrical connection between the rail and the main body.

The present invention provides a cross beam of a canopy, which addresses the problem that existing cross beams cannot simultaneously ensure convenience of assembly and guarantee stability in use. The present cross beam of a canopy comprises a plurality of hollow elongated beams, an inner side surface of each of the beams has at least one protruding and elongated protrusion along a length direction of the beams, each of the protrusions is provided with an mounting hole or a mounting groove penetrating along the length direction of the beams, at least one long rod is inserted into the mounting holes or the mounting grooves to connect all the beams in series, and two ends of the long rod protrude out of the beams and are detachably connected with a locking fastener respectively. The present invention ensures convenience of installation and guarantees the assembled cross beam has good stability.

A connection node assembly for use in connecting an upper prefabricated building module to a lower module. Hollow vertical edge supports of the building modules have top and bottom connection parts. A connecting bolt can be passed through the top part of an upper vertical support in the upper building module and seated within the bottom part of that vertical support with the shank extending downward. The shank engages a threaded aperture in a connecting nut secured within the top part of a corresponding lower vertical support in the lower building module. Diaphragm plates sandwiched between the upper and lower vertical supports are used to tie horizontally placed modules together.

An H-beam joint structure for joining ends of H-beam steel materials adjacent to each other. The steel materials have a flange and a web. The joint structure includes: a transmission plate arranged parallel to a front surface of the web on at least one side of the web of the H-beam and the steel material, and welded to a back surface of the flange; and a coupling plate provided in close contact with the transmission plate to connect the H-beam and the steel material. A web of the H-beam, the web of the steel material and the transmission plate are bolted via the coupling plate. As a result, there is provided an H-beam joint structure which has a joining strength equivalent to a conventional joint structure for an H-beam, and also which can easily be constructed to have less parts and make front surfaces of the flanges flat.

The present invention relates to a truss that allows the formation of an arc when connected with other trusses and that creates an optimal angle that generates a lower calculation effort in the structure.

The present invention also relates to an arched structure comprising a plurality of such trusses and to a shed comprising a plurality of arched structures.

Structural truss panels include first, second, third, and fourth horizontal elongated members and first and second vertical elongated members fastened to the first, second, third, and fourth horizontal elongated members. The first and fourth horizontal elongated members form respectively a top and a bottom of the structural truss panel. The first and second vertical elongated members forming respective sides of the structural truss panel. The structural truss panel further includes and an angled webbing fastened between the first and second vertical elongated members and the first and second horizontal elongated members thereby creating an integrated web truss within the structural truss panel. The structural truss panel includes first, second, and third brace members forming a V-braced truss panel.
