A backbone rail for a roller coaster, comprising two rail pipes designed for vehicles to travel upon, and at least one, particularly main load-bearing backbone pipe not designed for vehicles to travel on, whose second moment of area is greater than the second moment of area of the rail pipes, wherein rail pipes and backbone pipe are connected to each other section-by-section by stiffening bulkheads, whereby at least one bulkhead has the following features: A transverse cross member, which extends in the orthogonal direction and connects the rail pipes with each other, and bulkhead plates, connecting at least one rail pipe with the backbone pipe, wherein at least one bulkhead plate is designed as a longitudinal bulkhead plate, whose main plane of extension extends perpendicular to the bulkhead plane, and which is attached to the backbone pipe in such a way that it runs tangentially into the backbone pipe. In addition, the invention relates to a roller coaster arrangement with such a backbone rail.

A support for a moveable office wall is disclosed, the support including but not limited to a plurality of support sections, wherein the plurality of support sections are connectable to form the support, wherein each of the plurality of support sections comprises an inner connecting surface for joining with another inner connecting surface of another support section.

A composite structural member for a building structure comprises a first elongate portion having a first end region and a second end region and a second elongate portion having a first end region and a second end region. The second end region of the first elongate portion is connected to the first end region of the second elongate portion so that the composite structural member provided thereby is substantially longer than either of the first and second elongate portions. The first elongate portion may comprise a first member suited for resisting high magnitude forces and the second elongate portion may be a second member, less well suited for resisting high forces but having lower cost per unit length. The composite structural member may be a rafter, especially a rafter of a portal frame.

A system for traversing an opening of a construction element the system including a elongated housing with two extendable elements configured to reside at least partially within the housing. The extendable elements may extend beyond the housing and may include flanges or ledges which may engage the ends of a construction element, which may be a wall, and thus allow the system to traverse the opening of a construction element, such as a window or door. The system may allow a user to easily manipulate the system to fit a plurality of openings and reuse the system a countless number of times.

A truss includes an upper angle assembly; the upper angle assembly including an upper gap positioned in the lower angle assembly; a lower angle assembly, the lower angle assembly including a lower gap positioned in the lower angle assembly; and at least one of: a web member; and a bridge web member. The at least one of the web member and the bridge web member is positioned within the gap of at least one of the upper angle assembly and the lower angle assembly.

A support column extends in a longitudinal dimension and includes a plurality of outer hollow longitudinal structures. Each longitudinal structure defines an interior passage extending along a length of the longitudinal structure. The support column includes a plurality of inner members. The plurality of outer hollow longitudinal structures are aligned end-to-end along a single axis. The interior passages of the plurality of outer hollow longitudinal structures cooperate to define an interior passage of the support column. The inner members are aligned end-to-end along the single axis within the interior passage of the support column so that opposed longitudinal ends of each of the inner members extend to respective longitudinal ends of each adjacent inner member. At least one end of at least one inner member is longitudinally offset from every longitudinal end of the plurality of outer hollow longitudinal structures.

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.

Supplemental support structure for a hot aisle/cold aisle forming apparatus having vertical supports and a grid of parallel and perpendicular rows of elongated grid members attached to and supported by the vertical supports is disclosed. The supplemental support structure may include vertical support caps attached to the hot aisle/cold aisle forming apparatus above the vertical supports and the grid of parallel and perpendicular rows of elongated grid members and a grid of elongated cross supports.
