High-strength modular floor

A curved connector for flexibly fastening coupled floor modules together, wherein the curved connector is formed from a single-piece body comprising a perimeter curved portion and a central curved portion;

• wherein, between the perimeter curved portion and the central curved portion there is at least one passage that has curved walls formed by the perimeter curved and central curved portions, an inlet end and a locking end, said locking end comprising a locking mechanism;
• wherein the at least one passage is configured to receive therein an upper curved surface coupled to a lower curved surface of coupled floor modules, so that the curved walls of the at least one passage flexibly restrain a relative movement between the coupled floor modules in three Cartesian axes, generating a flexible coupling between the coupled floor modules;
• wherein, to flexibly restrict said relative movement the curved connector locks the coupling between upper and lower curved surfaces by means of a rotation movement thereof through a curved connector slot that said upper and lower curved surfaces have, so that the at least one passage receives said coupled upper and lower curved surfaces, and the coupled upper and lower curved surfaces enter the at least one passage from the inlet end and slide through said at least one passage to the locking end, activating the locking mechanism in a flexible locking position of the curved connector;
• wherein, in the flexible locking position of the curved connector, the at least one passage comprises a locking space that allows relative sliding between the coupled upper and lower curved surfaces, locking the curved connector in the flexible locking position of the curved connector and flexibly fastening the coupled floor modules together.
