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.

The present disclosure generally relates to an elongated section (101) for construction structures (300). The elongated section (101) comprises a plurality of sides (102), each side (102) comprising a first retaining channel (104) and a second retaining channel (105) adjacent a respective corner (106) of the elongated section (101), the first and second retaining channels (104,105) being a minor image of each other. Each retaining channel (104,105) is configured for engaging a respective retaining member (201) for supporting a structural panel (301) between the retaining members (201). Each retaining channel (104,105) comprises a channel slot (197) extending perpendicularly into the side (102), the channel slot (197) for engaging a first end (204) of the respective retaining member (201); and a channel end (198) opposite to the channel slot (197) for engaging a second end (206) of the respective retaining member (201).

A structural stud post assembly comprising a center receiver section having opposing receiver channels formed by side walls and angled flanges, and a pair of raceway inserts also defining a raceway channel for accepting wiring and equipment to be disposed in the raceway. The raceways can be installed in the receiver channels to accept and accommodate wiring and equipment. The center receiver comprises a thermal break at about a midpoint to prevent there from being a metal-to-metal thermally conductive pathway through the stud. The structural stud post may be used in the construction of modular building systems.

Disclosed is a terrace canopy, comprising a beam which a top side, a bottom side, an inner side and an outer side, and, in its cross-section, is provided with: a screen cavity and a U-shaped space at the bottom side of the beam which is located below the screen cavity and open at its bottom side. The U-shaped space is configured to hold a first profile and a second profile, different from the first profile, and is provided with: a first and a second connection means configured together to hold the first profile or the first connection means and a connection wall portion configured together to hold the second profile. By leaving the U-shaped space open at its bottom side and providing the connection means, it is possible to integrate other profiles into the beam.

A joist is disclosed. The joist includes a first leg portion, a second leg portion, and a central portion, wherein each of the first leg portion and the second leg portion define a first side, a second side, and a distal side, and one or more stiffeners defined within each of the first side, the second side, and the distal side of the first leg portion and the second leg portion.

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.

An energy dissipation device includes an inner tube, a core tube, an outer tube and a fixing member. The inner tube includes a first protruding structure. The core tube includes a second protruding structure, and the core tube is sleeved outside the inner tube. The outer tube is sleeved outside the core tube. The fixing member is connected to the inner tube, the core tube and the outer tube.
