The present invention relates to a facility comprising: a fixed frame fixedly installed on an outer wall of a veranda or a balcony of a high-rise building; a foldable evacuation box which can be unfolded in the form of a rectangular parallelepiped having an open top side and has and evacuation door on a side thereof; a fall prevention and evacuation means which can be structurally changed to an emergency stairway for fire evacuation; an evacuation box locking means which allows the foldable evacuation box to be unfolded in a rectangular parallelepiped form; a locking means which holds and fixes the fall prevention and evacuation means to the fixed frame; and an entry prevention door which prevents an evacuee from entering inside a veranda or a balcony from the foldable evacuation box through the fixed frame.

An adjustable deck shelf assembly has repositionable components to enable the assembly to be secured to variably dimensioned and assembled deck railings. A shelf is secured to a hinged shelf support board with a removable locking shaft in a mechanical interference fit to permit removal and storage of the shelf and assembly. Hinged truss shelf supports secured to support legs can be deployed to support the shelf and retracted for storage. An adjustable deck shelf/seat assembly incorporates variable-height outriggers attached to truss shelf supports and a variable-height shelf support board to enable the assembly to be arranged as a shelf or as a seat.

A deck apparatus for assembly with a pair of opposing brace frames interconnected by a pair opposing connector bases and a deck board top frame having a plurality of deck boards disposed thereon, the connector bases having opposing posts for being received in openings in a lower end of the opposing brace frames ends and the deck board top frame having posts for being received in an upper end of the opposing brace frames, and optionally attaching a stairs riser having a plurality of spaced-apart treads or a ramp riser for extending from a deck surface at a height to a vertically lower support surface.

An accessory holder for securing an accessory (such as a light strip) on a structure comprises a rail and a cap. The rail comprises a planar portion and two surfaces extending from the planar portion. The cap comprises an attachment portion and a cover. The accessory is held within a compartment defined by the planar portion, the two surfaces, and the cover. The attachment portion attaches the cap to the rail by engaging with ridges located on the interior faces of the surfaces.

A modular platform system utilizing a number of components including a platform. The platform is configured so that each of the components may interchangeably connect to any side of the platform. The components include, for example, handrails and stairways, as well as other platforms. The platform and most of the components are formed from single, continuous pieces of metal.
