Described is a method and apparatus for constructing light-weight, modular structures using special openC beams as a top and a bottom frame. Each openC beam comprises a vertical web member, a horizontal top flange extending perpendicularly in a first direction from the vertical web member, a horizontal bottom flange extending perpendicularly in the first direction and substantially parallel with the horizontal top flange and a upper vertical tab extending substantially perpendicularly from a distal edge of the horizontal top flange away from the horizontal bottom flange. Vertical posts are installed in one or more cutouts in the horizontal top flange of each openC beam and a planar surface of each of the vertical posts rests against the horizontal top flange for added support.

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.

Disclosed herein is a steel thermal stud being capable to provide structural and non-load bearing characteristics. The steel thermal stud with more than one dual flange stud provides additional and separated penetration locations for mounting screws allowing multiple connection points on the screw. The Steel Thermal Stud with multiple stud walls for a fastener to penetrate to prevent the movement of the fastener in any direction, prevent deformation of the stud wall material, prevent fasteners from backing out by having additional contact with less potential movement, provide more pull-out strength, and more strip resistance of the fasteners during installation.

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.

The present anti-ballistic shelter is a reinforced unit 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 end and side wall of the unit is reinforced with wall studs that penetrate the unit's structural framework. Even though these wail studs are welded into place, penetration of the wall studs into the framework ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

A scaffold includes a U-profile beam having an outwardly-open U-profile in which a scaffold platform is releasably hooked by mounting hooks. The U-profile beam has a perpendicular wall delimiting the U-profile and a guiding and fastening groove delimited by inwardly-extending groove reach-behind protrusions delimiting a locking space for releasably locking a locking element reaching behind the protrusions. An anti-lift-out and support element has an anti-lift-out element extending over the hooks to prevent lifting out. A support element fixed to the anti-lift-out element extends perpendicularly from the anti-lift-out element to a support element end for supporting the support element on the wall. The anti-lift-out element has a through-opening designed so that the fastening element moves the locking element toward the fastening element longitudinal axis and perpendicularly to the groove through the through-opening. A method secures scaffold platform mounting hooks against lifting out from a U-profile beam using an anti-lift-out device.

One embodiment provides a pre fabricated kit for assembling a supporting framework comprising a plurality of customized beams or supports with a connection openings/hole patterns selected from a set of connection hole patterns and using a plurality of generic connectors which fit on the interior of the customized beams or supports.
