A floor panel is provided including a floor chassis, an acoustic-mat layer and a gypsum concrete layer. The floor panel may be prefabricated and quickly installed on the job site thereby cutting construction time and costs.

The present invention is a modular structural building method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

A steel wall stud has a rear wall, two parallel side walls, each side wall having a front end wall that projects away from interior cavity formed by the rear and side walls.

A modular truss joint is a web plate with at least three connectors. Each connection includes a web integrally formed as a portion of the web plate of a certain length. Each connection is positioned at a connector angle with respect to the other connectors. The connections have continuous flanges on a periphery of the modular truss joint. Each flange is oriented transversely to the web. The connectors form a modular structure by each connecting to at least one wide flange body to form a moment resisting connection such that the modular truss joint resists flexure of the modular structure.

In an example, a structural frame is described. The structural frame includes a hub and a plurality of truss members. The hub includes a plurality of hub slots around a perimeter of the hub. The plurality of truss members are configured to couple with the hub and each other. Each truss member is a monolithic structure including: (i) a body extending from a first end of the truss member to a second end of the truss member, (ii) a truss fastener at the first end and configured to couple with a respective one of the plurality of the hub slots of the hub, (iii) a truss slot at the second end and configured to couple to the truss fastener of another one of the plurality of truss members, and (iv) one or more retainers extending along the body between the first end and the second end.

A deck framing system includes a ledger that has a joist support wall, a web wall extending perpendicularly from the joist support wall, and an overhang wall extending perpendicularly from the web wall and disposed parallel to the joist support wall. Each of a plurality of joist support brackets is configured to be coupled to the web wall of the ledger and includes at least one ledger attachment wing and a joist support portion that includes a pair of opposed lateral walls and a bracket web wall. Each of a plurality of joists includes at least one lateral wall and a deck support wall that extend from the at least one lateral wall. The at least one lateral wall is configured to be secured to one of the opposed lateral walls of the joist support portion.

The present invention is a modular structural building system and method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

A first post has a lower portion at a first floor of a multistory building and an upper portion at a second floor, and a second post has a lower portion at the second floor and an upper portion at a third floor or building-top structure. A post connection includes a horizontal cap plate and a vertical sleeve extending upward from the cap plate and having a bore with an inner dimension. The cap plate attaches to and covers the first post upper portion to prevent water intrusion into the first post. The second post lower portion has an outer dimension that is slightly less than the connection sleeve inner dimension so that the second post lower portion is slidingly received in the connection sleeve bore in an overlapping, telescopic arrangement. A retainer may be installed for engaging and supporting the second post on the connection.

An apparatus for connecting collar components to an elongate member is disclosed. The apparatus includes a frame structure having a central opening that is configured to receive an elongate member and that includes at least a first gripping station and a second gripping station. Each gripping station includes a reference surface and a clamp device that is configured to force a collar component against the reference surface. The first and second gripping stations are configured to control relative spatial location of a first collar component held by the first gripping station relative to a second collar component gripped by the second gripping station, prior to connecting the first and second collar components to the elongate member.

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.
