The present technology relates to beams having a cross section defining a plurality of channels and assemblies comprising the beams. The beams can be used to form a beam assembly that is installed inside the truck bed of a pick-up truck. A ladder loader and a solar panel assembly can be pivotably secured to the beam assembly along either the driver side wall or the passenger side wall of the truck bed.

A monolithic corner encapsulates one or more panels while maintaining structural integrity and maintain hygienic properties. The corner may securely receive one or more panels and provide flexibility to easily adjust the one or more panels. The corner may simplify installation and an ability to adjust connected panels without compromising safety, installation time, and sterility.

A metallic extruded profile has two parallel skins interconnected by a set of at least two webs running between extrusion edges of the profile and snap-fit features on joining edges permitting two instances of the profile to snap fit together along the joining edges, where a first web that is closest to snap-fit features of a first joining edge, is a curved web viewed from the extrusion edges. The curvature allows for both the curved web and skins to participate in snap-fit deformation, allowing for the deformation to be distributed over a large area, for a stiffer snap fit, and reduced plastic deformation.

A beam for formwork systems, with a transverse cross-section that is symmetrical with respect to an axis of symmetry and having, in succession:

a first portion with two C-shaped profiles, which are arranged mirror-symmetrically with respect to the axis of symmetry, with mutually opposite cores and cavities directed outward, connected by a plate for connection between two mirror-symmetrical wings thereof,

a connecting element, which extends along the direction of the axis of symmetry, between the plate for connection and a base,

a second portion with two protrusions which extend from the base and are provided with transverse end elements.

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 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 beam article for a vehicle includes a plurality of separate elongated metal sheets attached together to form generally planar walls of an elongated tubular structure. At least one of the plurality of separate elongated metal sheets has a shear wall that is disposed along a hollow interior of the elongated tubular structure and is attached at opposing walls of the elongated tubular structure. At least one of the plurality of separate elongated metal sheets comprises an edge that abuts a side surface of an adjacent one of the plurality of separate elongated metal sheets to define a non-radiused perpendicular weld corner along the elongated tubular structure.

The present invention is a support structure including elongate hollow cylinder and flat plates secured thereto. A first rigid flat plate is horizontally disposed in overlying relation to each hollow cylinder and a second rigid flat plate is horizontally disposed in underlying relation to each hollow cylinder. Stress-distributing strengthening members are circumferentially positioned about the hollow cylinder and secured to their associated rigid flat plates. A key may extend from a first end of each hollow cylinder and a mating socket may be formed in a second end of each hollow cylinder to facilitate end-to-end interconnection of a plurality of hollow cylinders.
