A flooring element is used in a raised floor having removable flooring panels and a supporting structure and having a load bearing surface. The flooring element includes a roll of flexible sheet material mounted on the flooring element. The flooring element may include a flooring stringer or an insert. After removal of an overlying flooring panel to reveal an opening to a sub-floor void, the roll of flexible sheet material may be extended from the roll and affixed to an attachment means at an opposite side of the opening so as to substantially cover the opening and provide a warning of a removed panel.

A double-floor member includes at least one first guide rail (24) that is fixed to an upper surface and at least one first connecting member (27) that is movable in the longitudinal direction of the first guide rail (24) and is engaged with the first guide rail (24) so as not to be separated upward from the first guide rail (24).

Disclosed is a supporting system for tiles to obtain floorings raised with respect to a reference ground. The supporting system includes a grid having at least three sides defining the perimeter of the grid and a supporting surface on which the tile can rest. At least one first seat is formed within the perimeter of the grid and at least one second seat is formed along the perimeter of the grid in correspondence of an arched recess. The supporting system includes at least one sustaining element resting on the ground and including at least one protruding body inserted in the first or second seat.

A modular floor system including webbing formed by a plurality of interconnected web sections. The web sections include attachment portions that are aligned in the grid layout. The support members are attachable to attachment sections of the web sections so that attached support members are properly aligned and positioned with respect to one another along the grid layout. The modular floor system includes tiles positioned upon and secured to the support members to be supported above the ground surface by the support members. A utility space is defined by and disposed between the ground surface and the supported tiles. Utility cables can be routed through the utility space.

A portable support platform may include a plurality of elongate segments arranged substantially parallel and adjacent to one another. The segments may be configured for spanning a space between two support points to support a user. The platform may also include a tying portion configured for flexibly securing the plurality of segments together. The platform may be arranged in a substantially flat open position for supporting a user and a substantially rolled up closed position for convenient transport and storage.

Installable temporary modular floor configured to be arranged on a surface to be protected so as to temporarily cover/face said surface. The floor comprises at least two panels, which are arranged side by side in adjacent positions, substantially coplanar to each other. The panels are provided on the relative sides with at least one recess that defines, with a corresponding recess made in one side of an adjacent panel, a seat. The floor also comprises at least one connecting plate, which is configured to be engaged in the seat to make the joint coupling of said panels.

A flooring element is provided for a raised floor including removable flooring panels and a supporting structure with a load bearing surface. The flooring element includes a warning element operable for moving between an inactive position in which the warning element is substantially concealed by the surface and an active position in which the warning element projects beyond the surface to form a visual hazard warning indicator. The flooring element may be for example a flooring panel, a stringer, a pedestal, an insert for a pedestal or an insert for inserting between a sub-floor void and a flooring panel.

An apparatus for destroying pathogens includes a platform and an LED matrix panel. The platform has a portion configured to permit passage of ultraviolet light therethrough. The LED matrix panel is disposed below the portion of the platform and includes a grid and a plurality of discreetly-controlled, ultraviolet light LEDs (UV LEDs). The grid defines a plurality of cells. Each UV LED is associated with one cell such that the cells direct the ultraviolet light emitted by the UV LEDs upwardly through the portion of the platform to sanitize an object supported on the portion of the platform.

The invention provides a raised access flooring arrangement comprising floor tiles mounted at different heights to create recessed spaces within which lighting elements may be mounted. The floor tiles are supported by a plurality of pedestal elements, each adapted for supporting tiles at the different heights.
