The present invention discloses a three-dimensional lightweight steel framing system formed by bi-directional continuous double beams. The three-dimensional lightweight steel framing system comprises beams, purlins, columns, wall bodies, floor slabs and lateral resistant mechanism comprises of diagonal support or bracing, wherein the beams are continuous double beams, and the continuous double beams are formed by combination of identical or different continuous single beams, and the continuous single beams are respectively arranged at the both sides of the columns, and the single beams are kept continuous at the junctions with the columns. The three-dimensional lightweight steel framing system simplifies the production of the lightweight steel member, and simplifies the on-site assembly by using bolts and nuts.

A joint connection structure of a building framework includes a column assembly including a column and a pair of gusset plates connected to the column on opposite sides of the column and extending laterally outward from the column. A beam assembly includes a beam having upper and lower flanges and an end portion received between the gusset plates. The beam assembly is bolted to the column assembly. A channel is attached to one of the column and beam to facilitate connection of the beam assembly to the column assembly. The channel defines an elongate slot for attaching the channel to said one of the column and beam.

Disclosed herein is an apparatus for a building frame designed to create a building, in accordance with some embodiments. Accordingly, the apparatus may include a plurality of base plates. Further, the apparatus may include a plurality of top plates. Further, the apparatus may include a plurality of studs. Further, each stud of the plurality of studs may include an elongated stud body having an upper stud end and a lower stud end. Further, the apparatus may include a plurality of rafters. Further, each rafter of the plurality of rafters may include a first slab body. Further, the each rafter may include a first cuboidal body. Further, the apparatus may include a plurality of braces corresponding to a plurality of brace lengths.

A balcony includes a balcony assembly and a structural post and outrigger system. The structural posts provide structural support for buildings and include the outriggers that extend substantially perpendicularly from the structural posts to a location where the balcony assembly will be installed. The outriggers include a tube or beam and an end plate on an end of the beam distal from the structural post. The balcony assembly includes at least one long beam, a platform, and a locking mechanism on an end of the long beam. The locking mechanism includes a channel for receiving and securing the end plate of the outrigger. The balcony assembly is secured to the outrigger using fasteners.

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.

A fabricated self-resilient energy-dissipation double-steel-plate slotted shear wall structure includes steel columns, H-shaped steel beams and a shear wall assembly. The shear wall assembly includes left and right groups of slotted wall plates and is connected with flanges of the H-shaped steel beams through angle steel. Connecting ring plate assemblies are fixed to upper and lower ends of each steel column and each comprise an outer ring plate, an inner ring plate and a short side plate. A long side plate is fixedly arranged on each steel column tube and is connected with one slotted wall plate through a plurality of self-locking hasps. A plurality of pre-stressed steel strands are arranged on two sides of each long side plate.

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.

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.

A balcony includes a balcony assembly and a structural post and outrigger system. The structural posts provide structural support for buildings and include the outriggers that extend substantially perpendicularly from the structural posts to a location where the balcony assembly will be installed. The outriggers include a tube or beam and an end plate on an end of the beam distal from the structural post. The balcony assembly includes at least one long beam, a platform, and a locking mechanism on an end of the long beam. The locking mechanism includes a channel for receiving and securing the end plate of the outrigger. The balcony assembly is secured to the outrigger using fasteners.
