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.

A guard rail system is provided. The guard rail system includes posts and rails. The posts include a base, a body and a plurality of rail supports. In one embodiment, a stacking fin extends from the base for fitting into an opening defined in a top portion of a corresponding post that is in an upside down orientation to allow two posts to be stacked together. In another embodiment, body and rail supports are integrally formed from the same material. In another embodiment, openings are defined in the body to act as rail supports.

A support assembly for a screen enclosure includes a collar device having a sleeve section with a central passageway for receiving an upright post of the enclosure and permitting the sleeve section to be adjustably positioned and fastened to the post. At least one channel is attached exteriorly to the sleeve section for receiving and being secured to a respective structural beam such that the beam is supported by and extends transversely to the upright post. The structural beam includes wide front and back face sections interconnected by narrow top and bottom side sections. At least one of the face sections has a spline groove formed longitudinally therethrough for receiving a screen panel and complementary spline component to secure the screen panel to the structural beam.

A paver having a length and a width. The length of the paver is about 4 feet, and the width of the paver is about 2 feet. The paver weighs about 400 pounds, and has a railing post mounted adjacent a width edge. The paver may be a part of a system of railing and non-railing pavers.

A staircase is provided that includes a column and steps. Each step: is coupled to the column and extends outside of, and away from, the column; includes a tread surface; and can move longitudinally along the column. The staircase can transition to a plurality of states by an actuation system, including closed and open states. The closed state includes the steps positioned at the upper end with the tread surfaces of the plurality of steps oriented around the upper end and coplanar to a flooring surface of the upper floor. The opened state includes the steps positioned at varying distances longitudinally along the column from the upper end towards the lower end so as to form spiraling steps around the column between the upper and lower floors. The steps can move longitudinally along the column for positioning in the closed and opened states.

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.

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.

A guard rail system is provided. The guard rail system includes posts and rails. The posts include a base, a body and a plurality of rail supports. In one embodiment, a stacking fin extends from the base for fitting into an opening defined in a top portion of a corresponding post that is in an upside down orientation to allow two posts to be stacked together. In another embodiment, body and rail supports are integrally formed from the same material. In another embodiment, openings are defined in the body to act as rail supports.

A deck system according to an example of the present disclosure includes a deck post cap having opposing first and second sides, with the second side being attached to an end of a deck post, and the first side including an aperture. A light post is provided that includes opposing first and second ends. The first end of the light post is received into the aperture, and the second end of the light post includes a slot that extends across the second end in a direction transverse to a central longitudinal axis of the light post. The slot can be used to receive string lights.
