<p>The floor (1) has a covering structure (2) vertically displaced by a motorization unit (3) from an emerged position to an immersed position, and inversely. The motorization unit is connected to the covering structure by chains. The structure has side rails (4) constituted of a plastic casing, where the casing receives a beam. The beam is made of concrete that is cast and reinforced with a metallic frame. The motorization unit has electromechanical motors distributed on the circumference of the structure to wind or unwind the chains.</p> |
