A panel (20) having opposite surfaces (22, 24), and including sheets (42, 43) and elongated cores or voids (40). The cores/voids extend parallel along a first direction (X), are arranged mutually adjacent in a second direction (Y), and include an outermost core/void (40a) along a panel edge (26). Each sheet includes a medial portion (44, 45) between two adjacent cores/voids, a first lateral portion (46, 47) folded away from the medial portion over one adjacent core/void, and towards the second direction along the first surface, and a second lateral portion (48, 49) folded away from the medial portion over another adjacent core/void, and towards a negative second direction (−Y) along the second surface. The sheets include an enveloping sheet (43), the first lateral portion (47) thereof extending into a folded lateral region (50, 52) that at the panel edge is folded around the outermost core/void, and extends in the negative second direction back towards the second surface.

A composite construction element or panel system for use in construction of multi-storey structures, either as a prefabricated panelized system or as a modular system. The composite construction element comprises two mass timber subpanels joined at a distance to form a hollow core, through which various building services (e.g. HVAC or electrical systems) and/or insulation may be integrated. When used as a modular system, after assembly, the two subpanels become one structural entity of increased structural capacity while providing a hollow core to provide/deliver desired building services.

A lightweight, interlocking, freestanding, reconfigurable, all-weather wall system for use in law enforcement, emergency services, and military training. The wall system may comprise a plurality of wall panels and a plurality of panel interlocking connectors capable of temporarily connecting two or more wall panels. The modular wall system may be capable of being assembled and disassembled without the use of tools.

A truss includes a plurality of truss members, each truss member formed from a unitary folded blank of sheet metal to create a main panel, and proximal and distal flanges and a horizontal panel each extending perpendicularly from the main panel, the proximal flange of a first truss member is connected to the distal flange of a second truss member to form a truss. In one embodiment employing trusses formed of folded sheet metal, a plurality of interconnected truss modules, each truss module including a plurality of truss members, forms a plurality of oppositely extending horizontal flanges that collectively present the top and bottom surfaces of a cantilevered canopy.
