A truss hinge that includes a number of different labeled parts, where connections between the two different parts can constrain the truss to different angles.

Wall systems and buildings having such wall systems are disclosed. Such wall systems include parametric mullions each of which is constructed from a plurality of interconnecting components so that the wall systems may be disposed much closer to the building frame than conventional wall systems. Such wall systems may include panels disposed to form convex or concave facades. Such wall systems may also include decorative features superimposed over one or more panels or extending outward from the facade surface. The parametric mullions may be formed into trusses which may be used as part of a wall system or independently of such wall systems.

An apparatus for adjusting a haunch height and related systems and methods includes a support angle. The support angle includes first and second flanges, and a surface of the first flange includes a hole. The apparatus also includes a coil rod and a rotatable nut.

A resilient prestress-free steel structure includes the elastic centering beam and two pin-ended box column bases. The elastic centering beam includes two cantilever segment I-shaped steel beams, a middle segment I-shaped steel beam and buckling restrained high strength steel bars. The cantilever segment I-shaped steel beams are fixed to the two pin-ended box column bases, the middle segment I-shaped steel beam is connected between the two cantilever segment I-shaped steel beams, the buckling restrained high strength steel bars are symmetrically arranged. One end of each of the buckling restrained high strength steel bars is firmly connected with the web of each of the cantilever segment I-shaped steel beams, and the other end of each of the buckling restrained high strength steel bars is firmly connected with the web of the middle segment I-shaped steel beam. The resilient prestress-free steel structure is arranged in left and right symmetrical manner.

A multi-story building that includes a vertical support core and a plurality of floor plates is described, wherein fabrication of the building includes, in one embodiment, assembling each of the floor plates at or near ground level, and lifting each of the floor plates to a design level on the vertical support core. A system and device for securing one of the floor plates to the building includes employing a vertically-oriented lock-in bracket.

Modular shelter systems are described herein. In one aspect, the modular shelter system includes an endcap positioned at a first end of the modular shelter system. The endcap includes a first support arch; and an endcap frame. The modular shelter system also includes a second support arch positioned at a second end of the modular shelter system. The modular shelter system also includes at least one section assembly disposed between the first support arch and the second support arch. The section assembly includes a plurality of purlins oriented along a longitudinal axis of the modular shelter system.

A mounting clamp for coupling a mechanical component to a mounting bracket. The mounting clamp can include a set of clamp sections, including a first clamp section and a second clamp section, hingedly coupled and movable between an open configuration and a closed configuration. The first clamp section can have a first set of clasps and a first arcuate portion extending from a first base. The second clamp section can have a second set of clasps and a second arcuate portion extending from a second base. In the closed configuration the first and second sets of clasps extend in a first direction and define an attachment portion for attaching the mounting clamp to the mounting bracket and the first and second arcuate portions extend in a second direction, different from the first direction and define a retention portion for retaining the mechanical component therein.

A slide clip includes a first plate and a second plate coupled at a juncture. The first plate and the second plate form an angle at the juncture. The second plate has a first elongated slot, a second elongated slot, and a third elongated slot, each extending parallel with the juncture. The first elongated slot and the second elongated slot are each offset from the juncture a first distance. The third elongated slot is offset from the juncture a second distance that is greater than the first distance.

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.

A structural steel member connecting assembly includes a first connecting member and a second connecting member. The first connecting member is pivotally connected to a positioning portion of a first structural steel member and therefore can be swung. The second connecting member is pivotally connected to the first connecting member such that the two connecting members are rotatable with respect to each other. The second connecting member has a fixing portion coupled with a second structural steel member such that the longitudinal directions of the two structural steel members intersect. With the second connecting member rotatable with respect to the first connecting member, the installation angles of the two structural steel members can be easily changed in order to make a stable engineering structure. The structural steel member connecting assembly features convenience of, and flexibility in, use and has extensive applications.
