A flooring system combines a dimensionally stabilized sub-floor laminate with a dimensionally stabilized tile laminate, the sub-floor laminate and the tile laminate being held together by magnetic attraction. In one embodiment one or other of the laminates is magnetic, and the other has a ferromagnetic engagement sheet. In another embodiment, a magnetic intermediate sheet is placed between ferromagnetic strata of the two laminates. The tile laminate may include ceramic tiles, which may be glass or porcelain. Those tiles are substantially rigid. They have flat ground edges to provide abutting matching fit with adjacent tiles. On assembly, neither mortar nor grouting is employed. The sub-floor has pre-defined mounting hardware accommodations that permit the fasteners not to interfere with the flatness and fit-up of the laminates.

Provided are a box frame and an LED display. The box frame comprises a frame border for installing an LED module, the frame border comprises a plurality of connecting seats and a plurality of frames, each connecting seat connects two adjacent frames, the connecting seat and the frame are alternately connected to form a closed structure; and the frame comprises an inner plate, an outer plate, a partition, a first reinforcing structure and a second reinforcing structure, the inner plate and the outer plate are arranged at intervals, the partition is connected between the inner plate and the outer plate, so as to divide space between the inner plate and the outer plate into a first groove and a second groove, the first reinforcing structure is arranged in the first groove and the second reinforcing structure is arranged in the second groove.

A mechanism for supporting and positioning a glass floor unit relative to a base utilizing a support positioned to contact the glass floor unit. An adjuster interacts with a receiver fixed to the base. The adjuster includes a contact element which moves the support and exerts a force against the glass floor unit in an upward direction.

A skylight assembly, having framing members that define an interior space and rafters that span the interior space between framing members, the framing members having an upper support surface for supporting panes of glass, each pane having at least one structural glass panel and a thermal panel. A structural thermal break connected to each framing member provides a lower support surface. The structural glass panels are fully supported by the upper support surface. The thermal panel is supported by the lower support surface, and is sealed to the upper support surface by a spacer, forming an insulating glass unit therewith. The full support of the structural glass, independent of the support of the thermal panel, allows the skylight to be thermally insulated and walkable.

A glass anchoring system, for securing a pair of adjacent panels of structural glass to a mid support beam and creating a walkable glass. Each panel has a fastening edge and has an upper pane, a middle pane, and a lower pane. The middle pane has a cutout along the fastening edge. A pair of blocks fit within the cutouts and are laminated within the panels. When the panels are positioned upon the mid support beam, the blocks face each other across a gap between the adjacent panels. A connecting bar extends across the gap and into both of the blocks. A bolt extends in the gap, downwardly through the connecting bar, and tightens against the connecting bar as it secures to the mid support beam.

An image display apparatus includes: a transparent board that transmits visible light; a screen that is provided on one surface of the transparent board; a projector that projects an image toward the screen from the other surface side of the transparent board; and a support unit that supports the transparent board from the other surface side. The projector is disposed outside of the space that is enclosed by the transparent board and the support unit.
