A modular show stage apparatus includes a foldable base, a front-left pole assembly, a front-right pole assembly, a rear-left pole assembly, a rear-right pole assembly, a plurality of cross poles, and set of curtains. The front-left pole assembly, the front-right pole assembly, the rear-left pole assembly, the rear-right pole assembly are perimetrically mounted to the foldable base. The plurality of cross bars is mounted to the pole assemblies and functions as the roofing structure for the modular show stage apparatus. The set of curtains is attached to the plurality of cross poles so that the rear side, the left side, and the right side of the modular show stage apparatus can be covered. The set of curtains also slidably positioned about the front side of the modular show stage apparatus so that the foldable stage can be open and closed for the audience.

A mobile entertainment stage which when deployed has a stage floor size of approximately twenty feet by sixteen feet, a gross trailer weight of seven-thousand pounds, an overall trailered height of six feet, eight inches, and a standard bumper hitch coupler allowing for a broader range of vehicles for towing. The stage front can be on either side of the stage. The trailered length of the invention is twenty-six feet but includes a break away or fold away hitch to decrease the overall length to approximately twenty-three feet. The length, width and height of the invention allows it to be stored in many garages

A modular platform system includes a plurality of tiles, legs, beams, and brackets. Peripheries of the tiles and top surfaces of the beams are configured so that the tiles can snap on to the beams, allowing for easy creation of a platform. The beams, legs, and brackets are all configured so that the beams and legs are easily connected together for platform system creation.

A spherical screen module unit includes a sector base including a sector carrier having an inner and outer arc edges; arc length of the outer arc edge is greater than that of the inner arc edge. An inner ramp frame is on the sector carrier and closer to the inner arc edge; an outer ramp frame is on the sector carrier and closer to the outer arc edge. When the spherical screen module unit is on a spherical screen assembling surface, minimum distance between the inner ramp frame upper surface and the spherical screen assembling surface is first height; maximum distance between the outer ramp frame upper surface and the spherical screen assembling surface is second height which is greater than the first height. A spherical screen structure including spherical screen module unit facilitates the module unit disassembly for repair, maintenance, or angle adjustment, and increases applicability in different environments.

A floor structure system may have a hub with a plate with an upper surface. A beam connector may be connected to the upper surface. At least one pin may extend from the upper surface. The pin may be adapted to connect with a rod or a cable extending generally transverse the pin direction. The rod or cable may have an aperture adapted to receive the at least one pin. The system may also have a beam attached to the beam connector.

A scaffold apparatus may have a saddle with a platform and two spaced apart parallel sides extending above the platform. The apparatus may also have a beam having a beam flange attached to an end portion of the beam. The apparatus may also have an upright connector with a bottom portion, where bottom portion may have an insert, and a plate attached to the bottom portion.
