The platform comprises, over at least one of its faces, opposite the face of an adjacent platform, with the interposition between the two opposing faces of a gap corresponding to the small clearance necessary for the independent movements of the two neighbouring platforms, a fillet 6, 7 running over the length of the said face and interacting with mechanical moving 16, 17 and guiding 18, 19, 22, 23 means, it being possible to move the fillet between an active position in which it comes to occupy the said gap, being brought into contact with the structure of the neighbouring platform, and a withdrawn position in which the fillet is then retracted inside the overall structure of the platform. <IMAGE> |
