The present invention relates to metal framed wall components with self-locking fixed and sliding connections between support members and crossing connecting members without using fasteners to connect the two crossing metal framing members together. Different variations of the shapes of the connecting members as well as the location and shape of the notches, ledges, tabs and notched-tabs are used between the members at the holes, punch-outs or indentations all determine the self-locking connections.

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.

A prefabricated post assembly is proposed. The prefabricated post assembly includes a vertical post having at least one assembly surface and a horizontal post having an assembly module mounted at an end thereof to be coupled to the assembly surface, in which at least one upper insertion hole is formed at an upper portion of the assembly surface and at least one lower insertion hole is formed at a lower portion of the assembly surface.

In accordance with the present invention, an elevator core structure includes an elevator frame (120) separated from a main frame (110) and extending in a longitudinal direction of the main frame (110), and a guide frame (130) formed on an inner surface of the elevator frame (120). Here, the elevator frame (120) may be formed by stacking a plurality of frame segments (121), and a guide frame unit (131) forming the guide frame (130) may be mounted to one surface of each of the frame segments (121). The present invention exhibits an effect of early-constructing the elevator frame regardless of a construction schedule of a main frame of a building.

A bracket assembly comprising a first bracket member associated with a first side of a structural element, a second bracket member associated with an opposed second side of the structural element, and wherein the first bracket member, the second bracket member and the structural element are fastened to one another using one or more fastening assemblies.

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 deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall and an overhang wall extending perpendicularly from the web wall. First and second joist support brackets include a joist support portion and a pair of attachment wings, where each one of the pair of attachment wings contacting the web wall of the perimeter support member. First and second joists each include a deck support wall and a lower wall. The deck support walls of the first and second joists are disposed between the overhang wall and the joist support portions, and the lower walls are disposed between the joist support portions and the joist support wall.

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 building system and a method of making and assembling the building system. In particular, the present invention relates to a footing for a building structure, the footing comprises a plurality of precast concrete layers, each precast concrete layer comprising reinforcement bars and a plurality of apertures. The footing further comprises a base structure comprising a base plate and a plurality of alignment bars protruding from the base plate. The footing is configured such that when the plurality of precast concrete layers are positioned on top of one another, the plurality of alignment bars of the base structure extend through the respective apertures of each precast concrete layer. Furthermore, the present invention relates to a building structure having one or more building modules.

Adjacent concrete wall panels are connected at the vertical joint by a shear connector structure that includes a metal connector angle embedded in a corner portion of one of the panels, and one or more threaded nuts or studs are welded to a flange of the angle. A metal shear connector plate has a hole for each threaded nut or stud and elongated holes or slots for the other concrete panel. After the panels are erected and positioned, the connector plate is bolted to the studs and self-tapping concrete anchor screws are inserted into the slots and threaded into holes formed in the other panel. The studs are formed by machinery weld studs to form a bore with threads at the welded end of each stud.
