The present invention provides a prefabricated floor panel system used in stay in place formwork for pouring concrete floors. The prefabricated floor panel system includes a top and has walls depending downwardly at an upper lateral edge of the wall from each outermost lateral edge of the top, a lower lateral edge of each wall having a ledge extending outwardly away from the top. A first ledge of one prefabricated floor panel system is capable of overlying another ledge of an adjacent prefabricated floor panel system to allow for the one prefabricated floor panel system to be joined to the adjacent prefabricated floor panel system to form a channel. The first ledge of the prefabricated floor panel system is provided with a reinforcing bar spaced away from the wall and the first ledge of the prefabricated floor panel system, the reinforcing bar being supported by a plurality of a reinforcing bar chairs spaced along the length of the prefabricated panel system, the reinforcing bar chairs being attached to the first ledge or wall such that there are no significant interfering structures projecting from a lower surface of the first ledge. The other ledge of the prefabricated floor panel system is free of interfering structures above the ledge to allow the first ledge of one prefabricated floor panel system to overlie the other ledge of an adjacent prefabricated floor panel system to allow for the one prefabricated floor panel system to be joined to the adjacent prefabricated floor panel system to form a channel.

The present invention relates to metal framed wall components with self-locking connections having overlapping connections be metal framing components by using: lip notches, lip-flange notches, web flange notches, notched tabs extensions, hooked tongue connecting receiver slot holes of adjacent metal component, hook tongue with receiver slot holes & wall plate, flange notches, hook tongue with bent tongue at receiver slot hole, hole projections having notches for flange or lip notches, lip flange notches at projection notches, longitudinal ends of flanges or lips and hook fingers overlap hole edge along with an adjacent flamed component having a hook tongue extending into receiver slot hole, web flange receiver slot hole overlapping adjacent metal component with the web flange receiver slot holes connecting the support member hole bottom, side or top edges and by interchanging the metal framing components at the longitudinal ends all two adjacent metal wall components to interlock together. In addition some of the same metal components are installed with the flanges extending upward from the bottom edge or downward into the bottom edge. The metal framed members can be the full width of support or between only the side edges of the hole opening or installed in various widths to connect together. The wall components spanning between support members connected by holes from support members, hooked receivers, hooked tongues, hook finger ends from the wall components.

A building information modeling (BIM)-based modular housing built with thin-wall channel steel can include columns and transverse beams adopt inward-flanging C-section steel or combined square steel arranged by oppositely buckling symmetric inward-flanging C-section steel. The columns and transverse beams are connected to each other together by base connectors, butting connectors, or crossed connectors. The joint is provided with webs, and can be used as a standard connector due to high strength, thereby realizing an internal-external nesting effect. A positioning groove arranged outside the joint and the inward-flanging C-section steel can be nested together in a concavo-convex manner, and then pressed and fastened by a fastening steel strip, thereby realizing effects of fastening and slippage prevention.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

A method of manufacturing a metal stud from a sheet of cold rolled steel includes the steps of: forming a central spine along a longitudinal centre of the sheet; forcing material outwardly from the central spine to form a thin central zone having a reduced thickness; forming embossments in at least the thin central zone; and forming the sheet into a generally C-shaped member. A stud made from a sheet of cold rolled steel includes a web and a pair of flanges. The web has an elongate central spine, a thin central zone and embossments extending outwardly from the elongate central spine. The pair of flanges extend generally orthogonally from the web. A stud system includes at least two studs and a bridging member extending between adjacent studs.

A strut channel support system including a first brace, a second brace, and a fastening mechanism connects at least two channel struts in a multi-orientable fashion. The first brace and the second brace both possess a U-shaped channel, a base, a fastener-engagement point, and a strut-engagement point. The base is terminally connected to the U-shaped channel, the fastener-engagement point is centrally integrated into the base, and the strut-attachment feature is integrated into the U-shaped channel. This permits the base to retain the rear portion of a strut channel. The U-shaped channel perimetrically braces the lateral sides of the strut channel. The first brace and the second brace attach to each other via the fastener-engagement point. The fastener-engagement point of the first brace and the fastener-engagement point of the second brace are mechanically coupled to each other. This enables a user to adjust the orientation between at least two strut channels.

A connector for a structural column includes a male element of a first column segment. The male element includes a male outer surface and a plurality of first fastener apertures. The connector also includes a female element of a second column segment. The female element includes a female inner surface and a plurality of second fastener apertures. At least one of the female element and the male element is swaged such that the female inner surface of the female element is sized to receive the male outer surface of the male element such that each of the first fastener apertures aligns with a corresponding one of the second fastener apertures. The connector further includes a plurality of fasteners configured to be received in the aligned pairs of first and second fastener apertures

The invention relates to a profile for arranging a component for a drywall construction, in particular a profile for a preferably ceiling-side fastening of a drywall, preferably a profile for a drywall comprising a panelled stud frame. Furthermore, the invention relates to a construction element set and to a drywall having such a profile. The invention provides a profile of the aforementioned generic type that can accommodate a possible relative movement of components of a drywall construction in an improved manner. This object is achieved according to the invention in that the profile has, in its cross section, substantially a U shape which comprises a web and two adjoining flanges, wherein the flanges are each designed to be resilient to the same degree and/or in the same manner in the direction which is substantially orthogonal to the web surface.

A fastener system is disclosed for use in securing an object to a channel beam such as UNISTRUT-type channel beam. The fastener system includes a spring nut installed in the channel beam and a spring nut clip removably secured to the spring nut. The spring nut clip inhibits rotation of the spring nut, particularly when a fastener is being removed from the spring nut.
