Multi-purpose transport and flooring structures, and associated methods of manufacture

Interlocking tile covering, comprising:

• a first monolithic structure having:
• a first surface,
• a second surface opposite the first surface and offset from the first surface in a horizontal plane parallel to the first and second surfaces,
• the first surface including a first lip located at two adjacent sides of the first structure with a first plurality of shaped protrusions, and
• the second surface including a second lip located at two other adjacent sides of the first structure and forming a first plurality of shaped apertures matching in number and shape with the first plurality of protrusions;
• and
• a first recess formed in the second lip and forming a first hole for receiving a first fastener to secure the first monolithic structure to a supporting structure;
• and
• a second monolithic structure having:
• a third surface,
• a fourth surface opposite the third surface and offset from the third surface in a horizontal plane parallel to the first and second surfaces,
• the third surface including a third lip located at two adjacent sides of the second structure with a second plurality of shaped protrusions, and
• the fourth surface including a fourth lip located at two other adjacent sides of the second structure and forming a second plurality of shaped apertures matching in number and shape with the second plurality of protrusions;
• and
• a second recess formed in the fourth lip and forming a second hole for receiving a second fastener to secure the second monolithic structure to the supporting structure;
• wherein each of the second plurality of protrusions mates with a corresponding one of the first plurality of shaped apertures.

An interlocking tile, comprising:

• a monolithic structure having:
• a first surface,
• a second surface offset and opposite the first,
• the first surface including a first lip located at two adjacent sides of the structure with a plurality of shaped protrusions, and
• the second surface including a second lip located at two other adjacent sides of the structure and forming a plurality of shaped apertures matching in number and shape with the plurality of protrusions;
• and
• a recess formed in the second lip and forming a hole for receiving a fastener to secure the monolithic structure to a supporting structure;
• the recess shaped and sized to receive a washer plate forming at least one washer plate hole aligned with the hole of the recess, for strengthening the tile when secured by the fastener.
