A modular perimeter frame system is described for forming a perimeter frame used in the construction of floors, walls and roofs of buildings. The modular perimeter frame system has a first modular sub-frame having one or two blunt end portions, and a second modular sub-frame having one or two overhang end portions. The blunt and overhang end portions are so dimensioned and shaped as to facilitate a continuous abutting engagement between at least two surfaces which meet at a corner of the blunt end portion and at least two surfaces which meet at a corner of the overhang end portion.

A stiffener 50 for construction elements for providing resistance against deflection and cracking is disclosed comprising a U-shaped cross-section with a web 10 and two flanges 20a, 20b extending transversely from the web 10 and having ribs 30 rising parallel, perpendicular or diagonal from the flanges 20a, 20b. The stiffener 50 is configured to be fixed within the construction element. A drywall stud and a ceiling section provided with a plurality of stiffeners 50 of the present disclosure spaced at desired locations along their length is also disclosed. Such drywall studs and ceiling sections comprising stiffeners 50 of the present disclosure reduce deflection of drywall partition and suspended ceiling system, respectively by up to 50%.

The present invention relates to using interlocking spacer braces between support members to construct wood and metal framed walls, floors and building trusses. Spacer braces have indentations, extensions, fingers that interlock horizontally, vertically or diagonally between support members. The spacer braces can form diagonal and lateral wall bracing, diagonal and vertical chords within building truss with either horizontally or vertical orientations, beams, hold-downs and shear walls. The spacer braces can be installed between wood or metal framing members.

A reversible structural component for use as a portion of a vertical frame in a modular wall system includes an elongate body extending between a first end and a second end thereof, a plurality of countersunk through-holes extending through the structural component, and a plurality of threaded through-holes extending through the structural component. The countersunk through-holes and the threaded through-holes are disposed on the elongate body between the first end and the second end so that the countersunk through-holes of the structural component are aligned with the threaded through-holes of a separate identical structural component when back sides of the structural component and the separate identical structural component are brought together 180-degrees relative to one another during use.

A structural beam and deck assembly containing portions of beam members interconnected by a deck assembly. Beam members have horizontal top and bottom flange elements interconnected by one or more vertical web member. The top flange of the beam members is serrated such that a series of serrations protrude horizontally in at least one direction from a top of the one or more vertical web member or are cut-out from the flange of a rolled shape. Adjacent beam and deck assemblies are installed such that attachment of one portion of a beam member to another results in the completed cross section of the beam member. In one embodiment, the serrated top flange and at least a portion of the web member are intended to be encased by a horizontal concrete slab. The slab material is capable of encasing all exposed surfaces of and curing around each serration to transfer horizontal shear forces between the serrated top flange and the slab material such that the beam members and slab behave compositely.

A modular perimeter frame system is described for forming a perimeter frame used in the construction of floors, walls and roofs of buildings. The modular perimeter frame system has a first modular sub-frame having one or two blunt end portions, and a second modular sub-frame having one or two overhang end portions. The blunt and overhang end portions are so dimensioned and shaped as to facilitate a continuous abutting engagement between at least two surfaces which meet at a corner of the blunt end portion and at least two surfaces which meet at a corner of the overhang end portion.

A bracket is combined with a rail that is to be attached to an elongate structural element by the bracket. The bracket includes a body and a bolt. The body is configured for attachment to the elongate structural element. The body defines a shoulder from which the rail is attached so that the rail is connected to the element. The bolt is engaged with the rail and is movable to engage the body. The body has a threaded passage to engage the bolt to fix the rail to the body.

A kit comprising components of an erectable shed, wherein the erectable shed is made of metal, in comprises at least two door panels, each of which is at least thirty four inches in height, wherein the components can be packaged in a box having dimensions of no greater than 48 inches×20 inches×10 inches, and wherein the space perimetered by the wall panels and side panels when the erectable shed is erected is at least 6 feet long by 40 inches wide and wherein the height of the shed when erected is at least 6 feet.

A rotatable forkend connection system is provided that includes a shank and a forkend connector. The shank is fixedly coupled to a device member and extends within the device member along a longitudinal axis of the device member. The shank includes a protrusion extending from the shank in a direction perpendicular to the longitudinal axis of the device member. The forkend connector is rotatably coupled to the shank and has an axis of rotation coaxial with the longitudinal axis of the device member. The forkend connector includes a recess configured to receive the protrusion. The protrusion and the recess are configured to restrain the forkend connector from moving along the longitudinal axis of the device member.

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.
