A demountable shelving unit with welded crossbar supports, open-channel upright supports, and channel support features. The welded crossbar supports and diagonal supports are slidably received within open-channel upright supports. Upper and lower crossbar supports include upright insertion blocks that are captured within the upright supports and horizontal connectors that extend through slots in the upright supports to connect two upright supports together to form an end unit. Shelf units are connected between two end units to create an assembled shelf. For a typical shelving unit, only eight bolts are needed to assemble each end unit and the shelf units attach to the end units with rivet-type quick disconnect fasteners that fit within teardrop shaped sockets in the upright supports. This results in a demountable shelf that can be assembled quickly and easily with only sixteen bolts per shelving unit.

A compact, temporary shelter that includes at least two vertical frame members aligned transversely over a base frame. Each frame member includes two opposite straight lower sections, two curved eave sections, two optional straight roof sections and a curved, central peak section. Adjacent frame members are interconnected by a plurality of purlins. The shelter includes an inner liner disposed over the inside surfaces of the frame members. The inner liner creates wall air spaces between two adjacent frame members and an upper attic and a lower living space that are partially isolated. When attached to an HVAC unit, air from the living space and flows and circulates into the wall air spaces between the frame members and into the attic. From the attic, air travels through a vent opening formed on an end cover to the outside environment. Located inside the shelter is a flexible air sock that connects at one end to the output port on the HVAC unit to evenly distribute the air into the living space. Because the frame member includes straight sidewalls and the inner lining forms a relatively high ceiling, greater storage and living space is created.
