Provided is a modular construction kit adapted to construct a raised temporary platform, the modular construction kit comprising one or more floor elements (1), wherein the floor element (1) comprises a monocoque structure (6) forming a floor section (21) and a flange section (3), wherein the flange section (3) is adapted to strengthen the floor element (1) and is adapted to be attached to a further floor element (1), wherein the floor elements (1) are load bearing and cooperate together to bear the load of the platform so as to form a self-supporting floor, without the requirement for a supporting floor frame.

A curved staircase including a double helix form with no center support column includes a plurality of stair segments, wherein each of the stair segments is formed from a plurality of rods coupled to a plurality of connecting nodes. The plurality of rods are arranged in a skewed tetrahedral geometry, which causes the plurality of stair segments to form a helical structure when the plurality of stair segments are coupled together. The plurality of rods form a spine on an underside of the plurality of stair segments. A tread is coupled to each of the stair segments. In alternate embodiments, the curved staircase may be formed from sheet metal creased to form a plurality of linear support locations and connecting nodes.

A first staircase part structure includes a staircase with a substantially U-shape in plan view having a first staircase part extending in a straight line in plan view from a floor of a lower floor, an intermediate part extending in a direction orthogonal to the first staircase part from an end on an upper-floor-side of the first staircase part, and a second staircase part extending from an end opposite to the first staircase part of the intermediate part substantially parallel to the first staircase part and in a direction of a foot of the first staircase part, a study corner formed by extending a stair landing formed in the first staircase part into an open ceiling space formed between the first staircase part and the second staircase part, a storage space formed below the second staircase part, and a storage rack disposed between the study corner and the storage space.

A staircase kit, device, and method that uses precut, fixed-sized components capable of producing building code-compliant staircases that can accommodate foot or more differences in home story heights. The design uses fixed-length stringers and adjustable height risers. The angle between the stringers to the floor changes depending on the height of the adjustable height risers and story height. The angles of the steps, stringers and banisters/handrails are configured to adjust with respect to the other components with the aid of turnbuckles and movable joints or bolts, thus keeping the steps and landings level at different story heights. This enables homeowners, generally exempt from contractor license requirements, to use a prefabricated kit to build code-compliant stairways in their homes with little or no staircase cutting or part modification.

A stairway apparatus for use with an endoscope storage cabinet includes a slidable door to open or close the cabinet's interior compartment. The stairway apparatus includes a base member disposed on a ground and placed against the cabinet, the base member having a first step with a front face, a rear face opposite the front face, and a top face connecting the front and rear faces, the front face having a lip coupled thereto and positioned to remain flush with the top face of the first step. The front face of the first step contacts front edges of the cabinet. The lip extends into the interior compartment of the cabinet when open and contacts side walls of the cabinet, thereby preventing lateral movement of the base member.
